Subjective well-being
The current study sought to analyze relationships between workaholism, authenticity, and subjective well-being. According to previous research, workaholism is negatively related to subjective well-being, while authenticity is positively related to it. However, no prior research has explored the potential relationship between workaholism and authenticity. A survey containing three self-report measures of the study variables was provided to a sample of faculty and staff members at a large Southeastern university. Findings supported previous research on subjective well-being correlates and revealed a significant relationship between workaholism and authenticity. Additionally, a partial mediating effect of authenticity on the workaholism and subjective well-being relationship was found. Implications related to the study findings and avenues for future research were also explored. Â

Visual Search Strategies of Elite Baseball Players During a Baseball Hitting Task
Harris, Nate
Murray, Nicholas P
Kinesiology
interceptive timing
Baseball batting is a cognitively demanding interceptive timing task that requires precision and power. Due to the quick duration of an at-bat, anticipatory visual cues and predictive eye movements are needed to have an accurate final fixation while initiating bat swing. Previous research has demonstrated expert hitters have superior dynamic visual acuity and superior visual search strategies. However, little research has examined the eye movement patterns and visual search strategies in an interceptive task. The purpose of this study was to examine the eye movement pattern differences in baseball players of varying skill levels and to observe changes in eye movements due to hit quality and pitch type. Sixteen participants with varying baseball playing experience were recruited (eight elite, eight sub-elite players) to perform a baseball hitting task. During the hitting task, participant's eye movements and fixation points were recorded using mobile eye tracking equipment. There were no significant differences in the time points of anticipatory eye shifts between the elite and sub-elite group. There was a significant negative correlation between the time point of the first anticipatory saccadic eye movement and hit quality [r(12) = -.547; p = .043] and a significant positive correlation [r(12) = .651, p < .05] for the average time lapse between the first saccadic eye movement and the last captured frame in the known conditions for all participants. Overall, the results demonstrated the role visual search strategies in interceptive tasks.

Training programs
School psychologists are trained in various models of problem solving and interviewing, however the interpersonal skills that play an integral role in consultation are not uniformly taught to trainees. The primary objective of this study was to examine the added value of an interpersonal skills training program on key outcomes of analogue consultation. Nine school psychology graduate students served as consultant participants, and participated in either an interpersonal skills training or control training. The online interpersonal skills training program was based on characteristics of effective consultants and strategies for building healthy relationships. All consultants completed a problem solving training based on stages of behavioral consultation. Thirty undergraduate students served as consultee participants, and worked with consultants in a problem solving activity about difficulties faced by college students.   The first dependent variable, treatment acceptability, measured consultee views of both a treatment proposed by consultants and of the consultants themselves. The second dependent variable, perceived consultant effectiveness, measured consultee views of the consultant's interpersonal and problem solving skills. The third dependent variable, follow through, measured how many steps of a follow-up activity consultees completed. The fourth dependent variable, treatment implementation, measured if consultees did or did not implement an intervention suggested by the consultant. A higher proportion of consultees in the experimental group reported implementing the intervention suggested by the consultant than those in the control group. Regression analyses found that experience of the consultee accounted for the most significant proportion of variance in the perceived consultant effectiveness variable. Higher levels of consultee experience were associated with lower ratings of perceived consultant effectiveness. A combination of consultee gender, consultee and consultant preexisting social skills, and consultee and consultant experience covariates impacted whether or not consultees implemented interventions suggested by consultants. These results indicate that a variety of factors influence key consultation outcomes. Study findings can be used to inform future research that examines how school psychology programs approach interpersonal skills training and provide information toward the creation of an explicit interpersonal skills training program in order to enhance the effectiveness of school-based consultation. Â

Darth Bane trilogy--Themes, motives
Darth Bane: The Monomyth's Dark Liberator is an original thesis based on Joseph Campbell's theory of the monomyth and Drew Karpyshyn's Darth Bane Trilogy. Campbell's theory of the monomyth has most commonly been called the hero's journey. For many years, the archetypal hero has been thought to be the only character that met the requirements of Campbell's theory. However, through Karpyshyn's trilogy of novels about the Sith Lord, Darth Bane, Bane illustrates what the epitome of an antihero is and also that he can make the monomyth his own. The antihero is one of the most fascinating character types in literature, and through Bane's complicated journey as an antihero, he proves that he embodies all of the qualifications set down by Campbell's theory and experiences a monomythic adventure. Â

Disaster Cycles
Storm-related flooding is one of the greatest disaster risks facing communities in eastern North Carolina. After flood events, communities of limited means may be incapable of pushing for reconstruction agendas that increase their disaster resilience. Recovery efforts driven by the agendas of outside agencies can perpetuate the pre-disaster status quo and result in a state of continued disaster vulnerability, highlighting the need for recoveries focused on the needs and viewpoints of the afflicted communities. Recently, the town of Windsor, NC has dealt with four floods reaching the 500-year flood stage. Data from participant observation and in-depth interviews with 16 stakeholders in Windsor are used to explore issues inhibiting long-term recovery. Specifically, I argue that part of the failure is due to a political power structure that favors assistance to regions with greater economic growth at the expense of economically vulnerable populations. Second, I show how repeated disaster trauma and disruptions to the recovery cycle have led many residents to distrust external agencies, misidentify the factors and risks for repeated flooding, and doubt the ability of the community to recover. I hypothesize that this attitudinal cluster is another key factor that mitigates against long-term recovery by inhibiting community building mechanisms. The goal of the research is to propose a more inclusive and holistic recovery model that addresses community viewpoints, actively seeks to create mutually beneficial relationships between residents and external agencies during recovery efforts, and views disaster recovery as a single step in a system that promotes community health and reduces vulnerability.

THE VARIATION IN STRENGTH DECREMENT OF LOWER EXTREMITY MUSCLE GROUPS AND BIOMECHANICAL PLASTICITY IN OLDER ADULTS
Moulder, Ashley
DeVita, Paul, 1955-
Kinesiology
Biomechanical Plasticity
Aging
Gait
Age-associated biomechanical plasticity (BP) has been established as the distal to proximal shift of joint mechanical output in old adults while walking. The cause of BP is still unknown, but changes in muscle strength of the lower extremities due to age are thought to be one of the underlying causes of BP. Old adults who had overall weaker lower extremities have been shown to have increased BP while walking on level and incline surfaces, however individual muscle groups have not yet been evaluated. We hypothesize that one causal factor of BP with age is that hip extensor muscles are more similar in strength in young and old adults than are ankle plantarflexor muscles, thus enabling old adults to walk with larger mechanical contributions from hip muscles as compensation for reduced contributions from ankle muscles. The purposes of the study were 1) compare muscle strengths of hip extensors and ankle plantarflexors between young and old adults, 2) verify BP in old adults by comparing hip and ankle joint torques and powers between age groups in level and incline walking & 3) examine the relationship between the relative strength in hip vs ankle muscles and the magnitude of BP in old adults during these gaits. 14 young (20yrs) and 22 old (76yrs) adults performed maximal isometric and isokinetic standing hip extension (20° of hip flexion) and seated ankle plantarflexion (15° of dorsiflexion). Age-based comparisons of muscle strength were made with 2X3 factor repeated measures ANOVAs, p<0.05. The same participants performed incline and level walking while ground reaction forces and 3D kinematics were obtained data. Walking joint torques and powers were calculated with inverse dynamics and were assessed using peak hip-to-ankle ratios with larger ratios indicating a larger shift of mechanical output to the hip. 2X2 factor repeated measures ANOVAs (p<0.05) for level and incline conditions were used to compare the torque and power ratios between age groups, with significant differences indicating BP. Pearson's correlations (p<0.05) were used to examine the relationship between walking power/torque ratios and the ratio of hip to ankle muscle strength in old adults. Old adults' hip extensor and ankle plantarflexor muscles were significantly weaker than young by 20% and 39%, (p<0.05). Old adults displayed a significant increase in hip/ankle ratios for both torque and power during level and incline conditions, indicating that the old adults exhibited BP (p<0.05). However, the correlations between ratios of hip and ankle isometric strength and hip/ankle peak torque and power were not significant for either level or incline walking. These findings suggest that there is a variation in strength decrement of individual lower extremities muscle groups due to age which may partially cause BP with age. However, we were unable to identify a relationship between the hip/ankle muscle strength ratio and BP, indicating the possibility of multiple factors contributing to BP.

Understanding Fatigue in Pediatric Sickle Cell Disease

Fatigue is a problematic symptom for adults with SCD and other pediatric populations, but less is known about the experience of fatigue for youth with SCD. The present study described the experience of fatigue in children and adolescents with SCD, and examined the combined and unique influences of anemia, sleep quality, and pain on fatigue in this population. Ninety youth with SCD (aged 8 - 17 years) and their guardians were recruited at their outpatient pediatric SCD clinic appointments. They completed interviews and questionnaires concerning the youth's experiences of fatigue, including fatigue frequency, duration, severity, level of interference with daily activities, and how it presents (e.g., general fatigue, sleep/wake fatigue, or cognitive fatigue). They also reported on the youth's pain episodes in the past year (pain frequency, duration, severity), and behavioral sleep quality. Their medical chart were reviewed to determine level of anemia (hemoglobin level) at their clinic visit. The majority (75%) of youths' guardians reported that their youth experienced fatigue in the last month, and that the experience was primarily episodic, occurring an average of 7 times per month, and lasting almost 10 hours on average. Adolescents experienced longer fatigue episodes and worse cognitive fatigue than children. Findings also indicated that poor sleep quality and pain contributed to fatigue experience. Also, sleep quality moderated the relationship between pain and fatigue, such that having poorer sleep quality worsened the effect of pain on fatigue presentation. Findings underlie the importance of fatigue as a common and multidimensional symptom of pediatric SCD that functions in relation to other disease symptoms. Clinically, these findings suggest the need for consistent screenings for fatigue symptoms and sleep problems in youth with SCD, as well as interventions targeting poor sleep and pain to address issues of fatigue in youth with SCD.

Community intervention to deter illegal parking in spaces reserved for the physically disabled.
Cope, John G.
Allred, Linda J.
Handicapped parking
Driving behavior
Illegal use of reserved parking spaces represents a major obstacle to the independence and mobility of people with physical disabilities. Using an ABACACA reversal design, the daily rates of illegal parking in four reserved spaces were examined across three types of sign displays: (a) a vertical sign alone or in combination with (b) a message sign that announced the possibility of public surveillance or (c) a message dispenser device that announced community involvement and dispensed politely worded reminder notes. The average rate of illegal parking dropped from 51.3% during the initial vertical sign phase to 37.3% under the message sign condition, followed by an increase to 50.4% when the message was removed. Illegal parking decreased to 24.5% when the message dispensers were first used (followed by an increase to 57.0% when they were removed) and to 23.7% when the message dispenser condition was repeated. Illegal parking in the final vertical sign condition failed to return to previous levels (M = 37.3%). Originally published Journal of Applied Behavior Analysis, Vol. 24, No. 4, Winter 1991

History
Artifacts
Conservation
North Carolina
The CSS Neuse was a Confederate Ironclad stationed in Kinston, North Carolina. Today, it is one of a few surviving commissioned Confederate Ironclads, and is forgotten by many due to its lack of significant military history. While the ship does not have an extensive military background, its recent history is interesting and complex. This research is a multidisciplinary analysis of the ship's excavation, conservation, and display. The Neuse is a testament to the importance of cooperation between archaeologist, conservators, and museum professionals. During its original excavation, the ship sustained damage that affected the future conservation of the wooden hull. Also, since conservation was in its infancy during the time of the excavation, treatments were experimental. This research seeks to understand the full history and condition of the ship and associated artifacts in order to effectively preserve and display them for the future. Chemical analysis was employed to determine effectiveness of past treatments as well as levels of degradation, and recommendations were included regarding future conservation treatments. The Neuse is an important piece of North Carolina material culture, and an understanding of effective conservation is essential to the life and future display of the ship. Â

Social skills training
Children who exhibit problematic levels of disruptive behavior frequently also present with social skills deficits and poor social relationships. The degree to which children establish and maintain interpersonal relationships is known to predict critical psychological outcomes in adulthood. Thus, social skills training (SST) is a frequently used treatment approach to teach or improve prosocial skills as appropriate replacement behaviors for inappropriate disruptive classroom behavior. However, many skills learned in SST often do not generalize to non-training settings (e.g., classroom) without actively programming for setting generalization. The goal of this study was to evaluate individual generalization procedures implemented by teachers directly in the classroom. The present study used an alternating treatments design to compare social skills training (SST) alone with three teacher-facilitated behavioral strategies to promote generalization. These included: 1) brief direct instruction of social skills with a visual prompt (i.e., positively-stated social skills rules visibly posted in the classroom), 2) verbal prompts, and 3) contingent reinforcement for the demonstration of social skills. Appropriate reinforcers were chosen from results on a preference assessment and teacher interviews.   Four second-grade male students, referred for excessive disruptive behavior and poor social relationships, participated in this study. Students were pulled from their classrooms twice weekly to receive SST throughout the study. Students received each generalization component in a rapidly alternating fashion and treatment conditions were counterbalanced among participants. Following the alternating treatments phase, generalization procedures were removed in a withdrawal phase (while SST was ongoing) and the most effective procedure was then re-implemented to verify that behavior change was a function of the treatment condition. Effectiveness of each treatment was determined by visual analysis and standardized mean difference effect sizes using data from direct observations of classroom disruptive behavior. Pre- and posttest ratings of students' conduct problems and social skills were assessed via teacher ratings. Finally, acceptability of each treatment was evaluated by teachers using the Intervention Rating Profile-15 (IRP-15).  Contingent reinforcement resulted in the largest decrease in disruptive behavior (d = 3.92) for all participants. Verbal prompting was somewhat effective (d = 1.38), but visual prompting (d = 0.25) had limited effectiveness. Additionally, SST alone was ineffective in producing a behavior change that generalized to the classroom (d = 0.04). As a result of the entire treatment package, conduct problems on the SESBI-R decreased slightly and social skills increased slightly on the SSiS. Teachers rated each procedure as acceptable, with contingent reinforcement most acceptable. Limitations include limited external validity and some variability in baseline conditions. This study demonstrates the importance of implementing similar reinforcement contingencies in the non-training environment. Â

THE FOUNDATION OF MUSIC
Castillo, Jean
Frank, Elliot
Music
Music, Classical Guitar, Foundation
Music is a powerful tool that can be heard all over the world. It is used as a means of expressing emotions, overcoming obstacles, and establishing an identity as an individual and as a culture. I plan to create a program that includes music from different areas of the world along with music that was written over a range of a few hundred years. This program will be unique and with the pieces I select I will demonstrate to the audience how although all the pieces are different they share a very common foundation. This presentation will be beneficial primarily to people who are not expert in the field of music. These people will learn that although music may come from different places and even different times they all share a common foundation or sets of rules.

Vernacular in Curves: The Mythologizing of the Great Lakes Whaleback
Lengieza, Joseph Thaddeus
Rodgers, Bradley A
History
The "whaleback" type of bulk commodity freighter, indigenous to the Great Lakes of North America at the end of the nineteenth century, has engendered much notice for its novel appearance; however, this appearance masks the essential vernacularity of the vessel. Comparative disposition analysis reveals that whalebacks experienced longevity comparable to contemporary Great Lakes freighter of similar construction material and size, implying that popular narrative overstates whaleback abnormality. Market and social forces which contributed to the rise and fall of the whaleback type are explored.

World War II
The Battle of the Atlantic was the longest, largest, and most complex military action of the Second World War. The battle involved Allied, Axis, and neutral nations, resulting in both military and civilian casualties. At various times throughout the battle certain areas became centers of activity. One such focal point occurred off Cape Hatteras, North Carolina, between January and July of 1942. During this time, several oceanographic, geographic, bathymetric, meteorological, and strategic factors converged and turned the waters off North Carolina's Outer Banks into a battlefield.  Using a particular convoy battle, the U-boat attack on Allied convoy KS-520 (15 July 1942) as a case study, this thesis seeks to adapt terrestrial battlefield survey techniques to analyze a naval engagement. Drawing from the dominant theoretical and methodological framework utilized by the United States Department of the Interior's American Battlefield Protection Program, the present study seeks to supplement this framework with the broader application of military science. It is hoped this modification will facilitate greater exploration of anthropological questions in addition to generating an adapted naval battlefield analysis technique capable of conducting similar anthropological inquiry of other Battle of the Atlantic engagements. Â

PSYDEKICK: REDUCING THE STIGMA OF MENTAL HEALTH ON ECU’S CAMPUS THROUGH THE CREATION OF A PEER EDUCATION PROGRAM
Clopper, Amy

Counseling Center
Mental health issues have become a growing concern among all colleges and universities within the nation. There is a lack of education and resources on these topics, which fuels the growing issue of mental health illnesses among college students. According to a survey administered by the University of North Carolina at Greensboro, 75% of their students were unaware of the university’s counseling services and 92% claimed to be uneducated on mental health prevention (Catanzarite & Robinson, 2013). Psydekick was created on ECU’s campus to provide students with valuable information on ways to cope with the six mental illnesses seen primarily among ECU students: anxiety, depression, stress management, suicide prevention, eating disorders, and substance abuse. As an acting partner with the Counseling Center, the focus of this organization was on the advocacy and peer education of mental health on campus. Through extensive research on the topic of peer education, it was found that the “social learning theory� supported that peers learn best from one another within a specific social context and results in more behavior change (Catanzarite & Robinson, 2013). Psydekick would function as a source of outreach to educate students on different ways to cope with these prevalent mental health issues while attending ECU. When individuals are given accurate information, they can successfully empower and encourage positive behavior change among their peers (Catanzarite & Robinson, 2013). Members in the organization planned to complete national peer education training through a program called BACCHUS to become certified as peer educators, as well as complete training provided by the Counseling Center on the six special topics of mental health. Throughout this process, Psydekick was successful in providing information and research on the importance peer education holds in the area of mental health, which has further led to a professionalized peer education program being formed in direct connection to the Counseling Center.

Novice Teachers’ Preparedness Towards Successfully Interacting with Culturally Diverse Student Populations
Young, Tremaine Ronnell
Chambers, Crystal Renée
Educational Leadership
Culturally Responsive Classroom Management
Teacher effectiveness is the most influential factor to student achievement. Systems of public education in the United States have traditionally centered on White, middle class norms, as suggested by the founding arguments of Critical Race Theory. However, in the past decade, national population trends show an increase in minority populations, particularly in the southeastern United States. This trend has resulted in a cultural mismatch between teachers who are not trained in strategies that are responsive to the needs of a diverse student population. Novice teachers in a rural school district in eastern North Carolina participated in a study to examine the degree to which they were prepared to successfully interact with their culturally diverse student populations through the lens of culturally relevant classroom management (CRCM), based on their training at either predominately White or Black postsecondary institutions. The study found that teachers trained at PWIs, although well-intentioned, enter the classroom far less prepared than their HBCU-trained counterparts due primarily to a lack of exposure to culturally diverse experiences both personally and within their teacher education programs. This inadequate preparation manifests itself through increased frustration and a disproportionate reporting of disciplinary incidents toward African American students. To address the training gap between PWI- and HBCU-trained teachers, the findings of this study suggests taking candidate dispositions toward diversity into account in the teacher selection process, providing ongoing, community-based diversity training, and professional coaching models to support the unique needs of novice teachers and their diverse student populations.

BUILDING A GLOBAL PERSPECTIVE AT HOME: A STUDY OF THE ACQUISITION OF A GLOBAL PERSPECTIVE BY STUDENTS OF GLOBAL UNDERSTANDING

virtual exchange
global perspective inventory
Universities around the United States use international mobility, such as recruitment of international students and faculty and study abroad of domestic students, as methods of achieving internationalization goals. However, only 15.5% of U.S. students have a study abroad opportunity during their academic careers. As universities strive to reach internationalization goals, methods of internationalization that do not rely on physical mobility of students need to be researched to ascertain whether goals are being met while students remain on campus. Classes that utilize Web 2.0 technologies allow students to communicate internationally with students at partner institutions globally. This research is using the Global Perspective Inventory (GPI), a measurement of global perspective acquisition, on students who enroll in GU at ECU. There are n=211 usable data points in the secondary data collected by the GU program. These data were analyzed using paired t-tests, and two-way mixed ANOVAs. Results indicate that students' scores improved significantly on the overall GPI and the following subscales: knowledge, personal identity, personal affect, and social interaction. Exploratory analyses indicate that specific demographics, such as gender, race, and interest level in study abroad, significantly interact with students' scores on specific subscales of the GPI. Therefore, virtual exchange is a measurable addition for campuses to consider for comprehensive internationalization.

The Influence of Depression on Medication Adherence Among Cancer Survivors
Anthony, Scarlett L.
Carraway, Marissa
Psychology
Depression, adherence, cancer survivors
Cancer survivorship is defined as “any person living with, through, and beyond cancer� which encompasses over 15.5 million Americans. Although rates of survivorship have increased, cancer survivor adherence rates are still not optimal. Adherence in cancer survivors includes engaging in a healthy lifestyle, attending regular surveillance appointments, and adhering to prescribed medications. Previous research has identified many factors that impact adherence in cancer survivors in cultural, biological, social, and psychological domains. Within the psychological domain, depression has been shown by previous research to impact adherence rates within many populations. The purpose of the present study is to examine the impact of depression on adherence rates among cancer survivors. Specifically, the current study will compare self-reported medication adherence rates of those who screen positively for depression with medication adherence rates of those who screen negatively for depression. Furthermore, the relationship between social support and adherence will also be examined in order to determine whether depression mediates the relationship between social support and medication adherence. Adult cancer survivors will be recruited through a family medicine outpatient center and pediatric oncology late-effects clinic. Participants will complete the Adherence to Refills and Medications Scale (ARMS) to assess medication adherence and the Patient Health Questionnaire - 2 (PHQ-2) to screen for depression. Demographic variables will also be analyzed individually to describe the study population. Descriptive statistics will be used to define the rates of adherence and depression. A t-test will be used to compare adherence rates of those who screen positive for depression versus those who do not. A linear regression will be used to determine if depression mediates the relationship between social support and medication adherence. Results of this study will support a larger study to build a biopsychosocial-spiritual model for predicting adherence among cancer survivors. Determining whether depression influences medication adherence or mediates the relationship between social support and medication adherence among cancer survivors will help providers to better identify patients in need of intervention and provide earlier intervention to prevent future decreased adherence and promote improved well-being for cancer survivors.

A Mortuary Analysis of the Structure 7 Cemetery at Town Creek, a Mississippian Site in the Piedmont of North Carolina

Town Creek is a prehistoric Native American site in central North Carolina. The Mississippian period occupation, from about A.D. 1150-1350, saw the most intensive use of the site. The community transformed from a residential village during the first half of the occupation to a necropolis later on. The cemeteries were created within the original public and domestic structures, the largest of which is Structure 7, the focus of this thesis. According to historic accounts of Southeastern Indian groups, communities were comprised of ranked clans made up of multiple kin groups that maintained separate household spaces. Through visual analysis and the spatial analysis of the distribution of burial attributes that include burial depth, age, sex, grave goods, body positioning and body orientation, I identify five spatially discrete groups within the Structure 7 cemetery. I argue that these five groups represent smaller social groups within the clan. The first group is a Central Square cluster that includes key members from the smaller social groups in the cemetery. There burials were arranged in a square, a formation repeated throughout Southeastern Indian ideology and site architecture. A small, Central cluster enclosed by the Central Square cluster, is consistent with ritual activity, as the interred are all children without any grave goods or other distinguishing attributes. A cluster in the northern part of the cemetery is made up entirely of adult males and children. This Northern cluster is interpreted as a politically-based grouping, as adult males most often held positions of political power in historic native groups. The children interred are likely kin or youth in line for positions of significant social status. Alternatively, they could represent ritual offerings associated with the interments of the adult males. Adult males, adult females, and children were found in the Southeastern and Southwestern clusters, which led to their interpretation as kin groups. Each of these groups was distinguishable through the distribution of specific artifact types and body positioning. The presence of all five of these groups contributed to the 50 person burial population in Structure 7, making it the largest cemetery at Town Creek. Its large size indicates that those interred in the Structure 7 cemetery were part of the largest and /or longest lasting group in the Town Creek community. Should other clans at Town Creek have had similar organization, the burial attribute patterning identified through this analysis may assist in the interpretation of other cemeteries at the site. Â

Reducing Effects of Sensory Disorders with Innovative Technologies

Sensory Processing Disorders affect 5-16% of school aged children. In addition, 40% of children with ADHD also share the Sensory Processing Disorder. Furthermore, sensory deficits are prominent in the learning environment and hinders many students from reaching their full potential.
SENSE-ational began as an Honors 2000 team at East Carolina University with the goal of helping reduce distractions in the classroom for students with sensory processing issues. Our original idea was to design, create, and manufacture kits that were to be distributed into those very classrooms. Due to COVID-19, and the lack of children in the classroom, we were unable to implement these kits. We needed to pivot in our attempt to help children who were struggling with online learning. We produced “DIY� YouTube videos of how to make sensory items. We now have a handful of quality, engaging, and useful videos on our YouTube channel, as well as our very own logo and a plan to move forward with our brand. We are utilizing the 3D printers in the Innovation and Design Lab at ECU to create and test our prototypes. In the future, we plan to donate all of our new designs to community schools here in Pitt County, so that our work throughout this project can have an impact on the children of Greenville, North Carolina. This will hopefully improve access to sensory items, and increase focus and learning for the kids of this community. In addition, we hope it will serve as a way for teachers and parents to view the benefits of sensory items in everyday school environments.

Cognitive impairment (e.g., dementia) presents challenges for individuals, their families, and healthcare professionals alike. It disproportionately impacts minoritized communities and often goes unassessed or undiagnosed, leaving missed opportunities for treatment and the use of supportive services for family caregivers. The primary care setting presents a unique opportunity to care for older adults living with cognitive impairment, who present with complex care needs that may benefit from a family-centered approach. An in-depth systemic review revealed that family-centered care and family engagement yields promising results including improved health outcomes, quality care, the patient experience, and caregiver satisfaction. Furthermore, it promotes and advances the core values of medical family therapy: agency and communion. An original quantitative study surveying 45 PCPs was conducted to better understand the influence of family engagement, race, and gender on primary care providers' (PCPs) diagnostic management and decision-making practices with older adults exhibiting cognitive impairment. Utilizing a vignette-based methodology, results revealed three main findings: (a) family engagement provides an opportunity for more efficient and accurate identification and diagnostic process for cognitive impairment, (b) family engagement allows for a clearer picture of patient symptoms and may present opportunities for PCPs to refer to specialists for diagnosis and treatment earlier, and (c) family engagement provides an opportunity to reduce health inequities by reducing variations in PCP perceptions of symptoms influenced by implicit bias. Recommendations for clinical care, training, and policies in primary care settings are provided using CJ Peek's Three World View. This dissertation further advances the knowledge of family-centered primary care, and influence of provider bias, when designing systems of care for older adults with cognitive impairment and their families.

Background: Cardiovascular and pulmonary rehabilitation (CVPR) is an underutilized resource that can aid in recovery from cardiovascular events and improve health related quality of life in pulmonary patients. Illness perception, which refers to how a patient views and understands their disease state, appears to have a role in the attendance and completion of CVPR. The current study investigated the relationship between illness perception and attendance and completion of CVPR, 6-minute walk test (6MWT) performance, and experience of depression and/or anxiety.
Methods: The present study used a longitudinal design that followed CVPR patients who were taking part in an intervention study which aimed to increase engagement in values-based health behavior change over 5-weeks. Participants completed baseline and follow-up measures of illness perception, depression, and anxiety, along with ecological momentary assessment (EMA) of illness perception on days which they were scheduled to attend CVPR. Demographic data and 6MWT scores were derived from the CVPR registry database.
Results: Results suggested that illness perception was not a significant predictor of CVPR absence (p=0.532) or completion (p=0.502) in this sample. Illness perception was associated with baseline 6MWT performance (p=0.004) and baseline 6MWT performance was associated (p=0.006) with more threatening follow-up illness perception for participants that completed the study. The relationship between baseline illness perception and discharge 6MWT was also evaluated for participants that completed CVPR, however, the relationship was not statistically significant (p=0.141). Finally, illness perception was significantly positively associated with baseline experience of both depressive (p<0.001) and anxious symptoms (p<0.001).
Conclusion: Results from this study suggested that there is a significant association between illness perception and both 6MWT and affective state, but not between illness perception and attendance and completion of the CVPR program. The study was novel in that it was conducted in a rural southeastern United States sample and in that it included a sample with heterogeneous disease states. Further research is needed to evaluate possible interventions addressing illness perception and to further investigate the relationship between illness perception and 6MWT performance.

Factors Associated with Choosing Social Work as a Major and Timely Graduation
Nelson, Allison
White, Kevin
Social Work
Social Work, Undergraduate, Education
A student’s major is a serious decision that has the potential to impact them for a lifetime. It is not a decision entered into lightly, taking into account many factors that will have a significant effect on their future successes. It is advantageous for faculty members and administrators to be interested in how students make these decisions, as the students are the key to the success of not only individual degree programs, but institutions at large. Ethically and strategically, those in authority should be addressing the factors related to retention of students from the moment they begin their freshman year. A deeper understanding of how students select their major could lead to better strategies on the part of advisors, departments, and whole institutions (Morgan, Jackson, Reeves, & Reece, 2017). For social work, assessing the mindset of prospective students could lead to better recruitment to strengthen and diversify the field (Bowie & Nashwan, 2018). Unfortunately, these factors are rarely studied in the realm of social work education, despite the clear benefits of doing so.

Social Support
The purpose of this study was to examine whether perceived social support was associated with self-efficacy for health promoting behaviors, and whether self-efficacy for health promoting behaviors predicts academic success for college students. Gender differences in perceived social support were also examined. Participants were undergraduate students at a large public university in the Southeast enrolled in an introductory psychology course. Data collection was completed through the use of a demographic form, the Interpersonal Support Evaluation List-College Version (Cohen, Mermelstein, Kamarck, & Hoberman, 1985), The Self-Reported Abilities for Health Practices Scale (Becker, Stuifbergen, Oh, & Hall, 1993), and the acquisition of participants' college GPA from official university records.   Perceived social support was found to have a significant positive association with self-efficacy for health promoting behaviors. Significant positive associations accounting for at least 10% of the variance in the dependent variable were found between the total score of perceived social support and the mean composite score of self-efficacy for health promoting behaviors, perceived belonging support and self-efficacy for exercise, perceived appraisal support and self-efficacy for psychological well-being, and perceived appraisal support and self-efficacy for responsible health practices. Gender differences in perceived social support were also found with females reporting greater perceived social support. Females reported greater perceived appraisal, tangible, belonging, and self-esteem support. No relationship was found in this study between self-efficacy for health promoting behaviors and academic success.   The results from this study may be useful to college students looking to improve their health and for health professionals working to promote health in the college student population. Choosing a social support intervention is likely to increase self-efficacy for health promoting behaviors, which have been linked to their actual implementation (Von Ah, Ebert, Ngamvitroj, Park, & Duck-Hee, 2004). Â

EXAMINING THE RELATIONSHIPS BETWEEN SHOULDER AND ELBOW SOFT-TISSUE PROPERTIES, THROWING MECHANICS, AND RANGE OF MOTION IN ADULT BASEBALL PITCHERS
Curran, Christopher J.
Domire, Zachary
Overhead throwing places extremely high loads on soft-tissue structures of the shoulder and elbow, causing pitchers to be injured at an alarming rate. Most researchers believe soft-tissue injuries in pitchers are acute manifestations of chronic microtrauma as a result of repetitive near-maximal loading. While specific mechanical factors and range of motion deficits have been reported as predictors of future injury risk in pitchers, it is unknown how the properties of the tissues themselves are changing in relation to these factors. The primary purposes of this research were to examine the structural and material properties of critical soft-tissue structures in the arms of adult baseball pitchers and to evaluate relationships between those properties and previously identified mechanical and range of motion injury risk factors. The reliability of a novel shearwave ultrasound elastography imaging protocol was developed and tested for inter- and intra-rater reliability and found to be reliable for 10/11 tissue properties. After the completion of protocol design, 26 healthy and currently competitive baseball pitchers participated in bilateral imaging, bilateral range of motion evaluations, and full-body 3D motion capture of the pitching motion. Significant bilateral differences were found in 7 out of the 11 tissue properties examined, displaying the effect pitching on the throwing arm. Pitchers with elevated shoulder kinetics during the pitching motion displayed decreased material stiffness of shoulder tendons, specifically the supraspinatus, infraspinatus, and biceps brachii long head. There were not any relationships between elevated elbow kinetic variables and the properties of the medial elbow or UCL. Pitchers with GIRD and TRM were found to have significantly stiffer supraspinatus muscle than pitchers without GIRD or TRM deficits and a significant interaction was found between Arm and GIRD for supraspinatus tendon stiffness. Additionally, interactions between Arm and TRM and Arm and shoulder flexion deficit were found for UCL stiffness. This research expands the field's understanding of the specific tissue changes occurring in pitchers with previously described injury risk factors. This research provides biological evidence strengthening the argument that soft-tissue shoulder injuries in baseball pitchers result from chronic microtrauma produced by repetitive exposure to extreme loads during the baseball pitching motion.

Archaeological Survey of Historic Bath : Locating the Early Eighteenth-Century Colonial Settlements in North Carolina's First Town
Flood, Lindsay N.
Ewen, Charles R., 1956-
Anthropology

Colonial North Carolina
Historical archaeology
Historic Bath was the first town to be incorporated in North Carolina. Following its incorporation on March 8, 1705, many individuals purchased property in the town, including a number of prominent figures who were influential in North Carolina's early history. Based on historical records, it is thought that much of the ownership in the early days of Bath was speculative, and not all of the property owners in the early eighteenth century resided in the town. The goal of the large-scale archaeological survey presented in this thesis was to determine which lots were occupied in the early eighteenth century. This research employed a `presence/absence' type of analysis, using temporally-diagnostic ceramics as an indicator of early eighteenth-century occupation. The survey revealed evidence for early eighteenth-century activity throughout the town, indicating widespread occupation in the early colonial period of Historic Bath. Results have been separated by their respective lot and their priority for further archeological research. Additional archaeological investigations can provide a more comprehensive picture of everyday life in Historic Bath and the roles of the individual inhabitants within the social structure of the town and the colony as a whole. Â

Local and Regional Aspects of Habitat Quality Jointly Affect the Biodiversity of Ephemeral Ponds

Biology, Ecology
The biodiversity of local communities is likely affected by both local habitat quality and by the quality of the landscape surrounding the locality. In pond environments, habitat quality may be affected by the kind of leaf litter present because leaf species differ in the kind of habitat structure they provide and the rate at which they release nutrients into the water. Landscape quality could affect diversity as well; some landscapes provide a richer pool of potential colonists. In addition, the plant community surrounding ponds could alter the influence of habitat selection: animals may prefer to colonize ponds that have litter which matches that kind of litter typically produced by plants in the surrounding landscape (e.g. if organisms are adapted to the litter types in the habitats where they occur). We conducted a split-plot randomized block experiment to examine how both landscape and local scale properties, and their interaction, affect biodiversity within temporary pond communities in eastern NC. We manipulated both the kind of landscape in which artificial ponds were located (open-canopy grassland, pine forest, and hardwood forest) and the leaf species (sedge, pine, or maple) present in artificial ponds. Ponds were open to colonization by amphibians and aquatic insects during the summer of 2010. We surveyed organisms in the ponds on a monthly basis and did a complete census of each pond at summer's end.   The kind of plant community (landscape) had consistent, strong effects on biodiversity throughout the experiment: ponds in open-canopy landscapes supported more species and different kinds of species than ponds in forested systems. Litter type affected biodiversity in the monthly catch-and-release samples, with more species in sedge treatments than pine treatments. We also found evidence from the monthly samples to suggest biodiversity was enhanced to a greater extent in open canopy ponds when litter from open canopy environments was present but that biodiversity in closed canopy environments was affected less by the kind of litter present. Our results highlight the importance of the terrestrial matrix surrounding ponds on biodiversity within the ponds, and it could aid conservation efforts aimed at maintaining the unique biodiversity of temporary ponds. Â

Characterizing the role of the Early Gene at 23 (E23) in Drosophila Melanogaster Oogenesis

Drosophila melanogaster (fruit fly) females undergo oogenesis to create oocytes from undifferentiated stem cells in the ovary. Similar to estrogen in humans, the steroid hormone ecdysone in fruit flies has a known role in facilitating oogenesis. The ecdysone signaling pathway is highly studied as it can help us draw parallels between Drosophila and human reproductive processes. After ecdysone binds to an ecdysone receptor (EcR), EcR activates transcription of many genes, such as E74, E75, and E78. These early genes code for proteins that are essential for Drosophila tissue repair, development, and reproduction. One of the early genes, the Early Gene at 23 (E23), is thought to be a target of ecdysone signaling, but little is known about its function.
Because E23 is expressed in multiple cell types and highly expressed in Drosophila ovaries, we hypothesize that E23 plays a role in Drosophila viability, reproduction, and oogenesis. To determine the role of E23 in Drosophila viability and reproduction, flies harboring transposable element insertions in the E23 locus were analyzed for potential mutant phenotypes. Our experiments using these lines suggested that E23 is not needed for viability or fertility. We also tested whether E23 affects oogenesis in more subtle ways, using high-resolution confocal microscopy, but results indicate that it does not affect early oogenesis or adult stem cell numbers. Although E23 does not play a role in Drosophila oogenesis, it may have other important functions within the fly.

Factors influencing community collaboration in public health initiatives in developing countries: A systemized review

Nursing
community collaboration

developing country
Safe drinking water is a basic necessity that remains out of reach for many people living in developing countries. Rural regions of Latin America are the least likely to have access to clean drinking water resulting in high morbidity and mortality (UNICEF, 2014). The World Health Organization (2015) urges community collaboration to address issues related to unsafe drinking water. For the past 12 years ECU College of Nursing has been working with community partners in Guatemala to address safe drinking water. Yet, it is unclear what factors contribute to the effectiveness and sustainability of community collaboration in public health initiatives, such as safe drinking water.
A systemized review of the literature was conducted to ascertain the current state of the science of community collaboration in public health initiatives in developing counties. Five databases were searched: PubMed, CINAHL, Embase, Sociological Abstracts, and SocINDEX. A total of 552 citations were retrieved and after deduplication, 524 citations remained. Three research team members independently reviewed the titles of articles. After exclusion criteria were applied to titles and abstracts, 77 articles were identified for the full-text screening. After the application of inclusion and exclusion criteria, 24 full text articles were included in the final review. The nine principles of community-based participatory research were used to rank level of community collaboration in the studies. Few studies (n = 3) had a high level of community collaboration, while most studies (n = 21) had a low to moderate level. High level community collaboration included empowering pre-existing leaders and strengthening pre-existing community networks. This review suggests ways to increase community collaboration in public health initiatives in developing countries and demonstrates a need for further research to determine effectiveness and sustainability through community collaboration in research.

A Synthesis of the Prehistoric Archaeological Investigations of Lake Phelps, Washington County, North Carolina
Pierce, Greg
Boudreaux, Edmond A., III, 1971-
Anthropology
Anthropology
Archaeology
During the mid-1980s, visitors and staff at Pettigrew State Park in Washington County, North Carolina discovered a series of prehistoric dugout canoes and associated artifacts in and around Lake Phelps. Beginning in 1985, archaeological investigations were undertaken at Lake Phelps to locate and identify prehistoric canoes. They also conducted a series of surveys aimed at collecting and identifying prehistoric artifacts. The work in these areas led to the discovery of 23 canoes, 19 of which have been radiocarbon dated, and the recovery of 5829 prehistoric artifacts. After these initial investigations, few archaeological investigations have been undertaken at Lake Phelps. Over the next 25 years the lake was only revisited five times, and all of this work focused primarily on the canoes.   This changed in 2007 when low lake levels again led to the discovery of a significant amount of cultural material. This caused a renewed interest in the prehistory of Lake Phelps, and it was the catalyst for this thesis project. At the request of the North Carolina Department of Parks and Recreation, I conducted a research project focused on the prehistoric occupation of Lake Phelps. This project had four main objectives. The first was to locate and integrate all of the previous research from the lake. These documents were held by a variety of agencies, many of which were unaware of the existence of outside documents. With the data from the Lake Phelps archaeological investigations spread about in this manner, it prevented an accurate and inclusive evaluation of the work done at Lake Phelps. The consolidation of these data in this thesis allows for a complete and detailed evaluation of the prehistoric occupation of the lake. This thesis also presents materials collected during fieldwork designed to fill in gaps in the data. This fieldwork consisted of a survey of portions of site 31WH12. This survey completed the controlled collection of the entire site that was begun in the 1980s. The material from the survey was analyzed and integrated with that of the previous work. All of the data from Lake Phelps are used to define spatial and temporal patterns in the prehistoric occupation of Lake Phelps. These patterns are used to generate a culture history for Lake Phelps. The final step of the project uses this model to generate a context for future work on the lake.  The results of the re-examination of the Lake Phelps data reveal a prehistoric occupation that began in the Late Paleoindian and lasted until the Late Woodland period, with the lake being abandoned before Europeans reached the region in the Eighteenth century. Archaeological investigations also show reveal four distinct areas of prehistoric occupation on the northern and western shores of Lake Phelps. An examination of the artifacts and canoes found in these occupational areas shows that they were used differentially throughout time, in many cases reflecting the larger regional settlement pattern trends seen across the rest of the North Carolina coastal plain. Â

Developmental Patterns of Cleistogamy and Chasmogamy in Triodanis perfoliata
Bernetski, Elizabeth
Goodwillie, Carol
Biology
Cleistogamy
Chasmogamy
Some plants exhibit mixed mating, in which individual plants utilize both cross and self-fertilization. Dimorphic cleistogamy is one form of mixed mating. In plants that display dimorphic cleistogamy, both chasmogamous (CH) and cleistogamous (CL) flowers may occur on the same individual. CH flowers are typical open flowers that are predominantly cross-fertilized. CL flowers are closed, lack petals, and are obligate self-fertilizing. Benefits of cross-fertilizing CH flowers are that the resulting offspring may have a high level of fitness; however, they have a high energetic cost, and the flowers rely on pollinators. In CL flowers, the ability to self-fertilize may benefit plants in that reproduction can occur without the need to find a separate mating partner. However, self-fertilization generates populations that have little genetic variation and results in higher levels of inbreeding depression. Although the fitness advantages of both flower types have been hypothesized, the factors that maintain this mixed strategy have not been fully explained. Triodanis perfoliata is a local annual plant that exhibits dimorphic cleistogamy. Observing the patterns of CH and CL flowers in Triodanis perfoliata may provide clarity to how a mixed mating strategy can be maintained. In a growth room study, individual flowers were observed to compare rates of development of the two flower types. Individual plants were observed weekly to determine the spatial and temporal development of CH and CL flowers throughout the lifespan of a plant. By sequentially numbering the nodes on the main spike of the plants, the type and developmental stage of each flower at the individual node was observed. Characterizing the spatial and temporal patterns of development of CH and CL flowers in Triodanis perfoliata may provide insight to the adaptive value of dimorphic cleistogamy.

Currently, there are many legacy enterprise software applications in active deployment that are outdated. These large legacy applications are rapidly becoming less practical for both the organizations they service, and for the organizations responsible for servicing them. Due to this problem, organizations utilizing legacy enterprise software applications are looking for feasible methods for overhauling them. This thesis establishes a process model for refining the initial concept associated with overhauling legacy enterprise software applications, and examines a case study of that process as applied to a real-world legacy software system. Â

Tobacco smoking is a worldwide epidemic that is responsible for diseases and death rates that surpass those attributed to a combination of other causes (e.g. cancer, HIV, accidents). A major mediator of tobacco-smoke related negative consequences is nicotine. Nicotine is an addictive poison that entraps users in a vicious cycle of constant drug seeking and reinforcement. Despite the public health policies and laws enforced to decrease the habitual smoking, it is still prevalent, especially among adolescents. According to WHO, 40% of children and up to 60% of teenagers are passively and actively exposed to tobacco smoke. Early life stages are more vulnerable and sensitive to environmental and life experienced stresses. At that stage, stresses can have enduring effects that not only persist until adulthood, but are also inherited to the subsequent generations. With respect to nicotine, a wealth of studies have investigated the dose and time-dependent effects of this chemical on multiple systems including cell lines and model organisms. However, the transgenerational effect of nicotine exposed during post-embryonic stages has not been reported. On the molecular level, an increasing number of popular findings that show the involvements of certain microRNAs in physiological processes have expanded to include response to nicotine. Nevertheless, a systematic profiling of microRNA expression levels is yet to be determined. In our study, we employed C. elegans as our model to investigate the transgenerational effect of nicotine exposure limited to the post-embryonic larval stages of the parent F0 generation. Two concentrations (20[mu]M and 20mM) were chosen based on previous studies. We investigated the effect of nicotine on the behavior of L4 C. elegans (N2) across three generations (F0, F1, and F2). Here we report that nicotine altered the sinusoidal locomotion, body bends, and forward and backward speeds across three generations. Such represented an enduring and heritable addiction initiated by parental post-embryonic nicotine exposure. In addition our qRT-PCR results showed that direct nicotine exposure throughout the larval stages (30 hours), altered the systematic miRNA expression profiles in L4 C. elegans in a dose-dependent manner. Through target prediction analyses coupled with background research, fos-1 was predicted to be a key mediator of the addiction-like behavior in C. elegans larvae. Conclusively, our results offer novel insights on the sensitivity of early developmental stages to nicotine exposure. The behavioral transgenerational effect as well as the parental altered miRNA profiles will set the basis for future miRNA transgenerational analyses coupled with target and pathway validation. With this in mind, the need for suitable reference genes for normalization and reliable interpretations is necessary. We dedicated our last objective to identify reference gene candidates to serve this purpose. Based on results from five statistical approaches (geNorm, NormFinder, BestKeeper, dCt method, and RefFinder), we report that the expression levels of tba-1 and cdc-42 were the most stable among all of sixteen compiled genes. Taken together, our work is preliminary for a new research direction concerned with nicotine that would help support public health policies and awareness campaigns to further stress on the risks and dangers of tobacco addiction.

EXPLORING EMPATHY AND SOCIAL SELF-EFFICACY IN ADOLESCENTS WITH A SIBLING WITH AN AUTISM SPECTRUM DISORDER

Psychology
self-efficacy
This exploratory pilot study investigated levels of empathy, social-self efficacy, and psychological well-being in adolescents whose siblings have been diagnosed with an Autism Spectrum Disorder. The purpose of the study was to determine whether there is a difference in the amount of empathy and social self-efficacy adolescent siblings of children with an ASD (TD-ASD pairs) possess compared to adolescent siblings of typically developing children (TD-TD pairs). The researcher hypothesized that TD-ASD sibling pairs would have higher levels of empathy and social self-efficacy when compared to TD-TD sibling pairs. It was also hypothesized that the two sibling groups would have similar levels of overall psychological well-being. Adolescents completed self-report measures pertaining to the three dependent variables. Statistical analyses were used to make comparisons among the two groups. Results of MANOVA and independent t-tests suggest that TD-ASD and TD-TD sibling pairs have similar overall levels of empathy, social self-efficacy, and psychological well-being. Further investigation into these constructs is warranted to provide more conclusive findings regarding the relationship between having a sibling with an ASD and the effects it may have on empathy, social self-efficacy, and psychological well-being in typically-developing siblings.

Islam and the West : Problematizing a Discourse of Dualism
Lean, Nathan Chapman
Maher, Derek F.
International Studies
Religion, General
"Islam and the West," a dualistic phrase that gained sudden ascendancy following the events of September 11, 2001, is used variously to refer to the mutual relationship between Muslims and those living in a sometimes ill-defined region called "the West." The binary phrase in question serves to reify what are depicted as incommensurate and incompatible opposites in terms of politics, culture, religion, and otherwise. This thesis argues that the perceived division between Islam and "the West" arises within a discourse that presumes, configures, and reinforces a relationship of conflict between the two. Coming from different viewpoints, the individuals examined in this thesis end up deploying similar linguistic maneuvers that advance their own ideological beliefs, reinforce their self-identities, and represent their respective values as universal. As a result, each group views the other as threatening and necessarily oppositional. An analysis of key terms and phrases used by influential scholars, political and religious leaders, and the general public within "Western" and Muslim-majority societies will reveal the constructed nature of the division between Islam and "the West." Additionally, this thesis will examine the ways in which other discursive practices such as selective representation, reification, and the deployment of charged stereotypes influence policy makers who seek to establish global positions of power. By problematizing the language that both sides of this perceived dualism use to represent themselves and the other, it will be demonstrated that the perceived conflicting relationship between Islam and "the West" results, in part, from the linguistic practices that each side deploys. Â

Possible Effects Of Climate Change On Induced Defenses In Tadpoles

Life history
Global climates are changing and the rate of change is expected to increase in the next century. Researchers predict that temporary ponds will be affected, resulting in shorter average hydroperiods (the amount of time a pond holds water). Species that live in these ponds will face increased stress due to these environmental changes, which may affect the timing of yearly events and alter community composition. For example, important pond predators, such as dragonfly nymphs, may emerge from ponds in the autumn instead of overwintering in the pond.
Amphibians are important components of temporary pond systems, and their tadpoles can exhibit a great amount of plasticity in morphology and life history traits due to environmental change. For example, tadpoles can alter their morphology in response to specific predators. These induced defenses have been found to increase survival with predators but to decrease fitness in the absence of predators; thus, the defenses are costly. This phenotypic plasticity also has limits, in that some species have not been found to use them and other tadpole species are limited in the circumstances in which they can induce changes.
I measured the morphological and life history responses (survivorship, larval period, and mass at metamorphosis) of tadpoles to simultaneous changes in hydroperiod and predator composition. I used Cope's gray treefrog tadpoles, Hyla chrysoscelis, as prey in an experiment that crossed two hydroperiod length treatments (short, long) with four predator treatments (caged Anax dragonfly nymph presence/absence x caged Belostoma water bug presence/absence) to address two questions. First, do the two factors of hydroperiod and predator presence interact either synergistically or antagonistically? Secondly, do tadpole responses, or their costs, to each predator differ and do tadpoles respond to the more lethal predator (Anax) when both predators are present?
I did not see evidence of morphological induced defenses in Cope's gray treefrog tadpoles, nor did I observe effects of predator presence or shortened hydroperiod on tadpole developmental rate, size or survivorship. There was, however, an effect of hydroperiod on the within-tank variance in tadpole larval period and mass at metamorphosis. For both variables, longer hydroperiods significantly increased within-tank variance relative to shorter hydroperiods.
The lack of morphological changes in my experiment runs counter to my expectations, but highlights the fact that induced defenses are context-dependent. The concentration of predator cue present in the water, conspecific density, and abiotic stressors may all reduce tadpoles' ability to respond to predators. Thus, some tadpoles may not be able to perform well in conditions with shortened pond hydroperiods and changing community compositions.

The extreme environment of the Qinghai-Tibet Plateau (QTP) provides an ideal natural laboratory for studies on adaptive evolution. Few genome/transcriptome based studies have been conducted on how plants adapt to the environments of QTP compared to numerous studies on vertebrates. Crucihimalaya himalaica is a close relative of Arabidopsis with typical QTP distribution, and is hoped to be a new model system to study speciation and ecological adaptation in extreme environment. In this study, we de novo generated a transcriptome sequence of C. himalaica, with a total of 49,438 unigenes. Compared to five relatives, 10,487 orthogroups were shared by all six species, and 4,286 orthogroups contain putative single copy gene. Further analysis identified 487 extremely significantly positively selected genes (PSGs) in C. himalaica transcriptome. Theses PSGs were enriched in functions related to specific adaptation traits, such as response to radiation, DNA repair, nitrogen metabolism, and stabilization of membrane. These functions are responsible for the adaptation of C. himalaica to the high radiation, soil depletion and low temperature environments on QTP. Our findings indicate that C. himalaica has evolved complex strategies for adapting to the extreme environments on QTP and provide novel insights into genetic mechanisms of highland adaptation in plants.

Information distribution
Emerging Hispanic communities in the U.S. have experienced barriers in health care access and health literacy. A program evaluation was conducted at a health department in eastern North Carolina to assess the preferred method of receiving health information by a sub-set of Hispanic adults. Evaluation data included an assessment tool completed by Hispanic adults receiving care at the local health department (LHD), key informant interviews, and 7 weeks of participant-observation at the LHD. The top three preferences for ages 18-35 were nurses (76%), doctors (76%), and family/friends/neighbors (70%). The top three preferences for ages 35 and older were family/friends/neighbors (65%), doctors (57%), and television (57%). The three preferences for the whole sample were doctors (68%), family/friends/neighbors (68%), and nurses (65%). The findings indicate a difference of preferences between the younger and older populations. Based on the results, a possible method to consider for distributing health information for the older adult Hispanic population may be to implement a CHW program, whereas methods to consider for distributing health information to the younger adult population may be through television, Internet, or radio.

Influence of Pre-pregnancy and During Pregnancy Exercise On Infant Heart Outcomes
Langford, Benjamin
May, Linda E.
Kinesiology
Maternal exercise during pregnancy is quickly becoming a new norm that has been shown to have benefits for fetal and infant development. Most studies examining the influence of exercise during pregnancy on infant outcomes have utilized women that were previously active and the exercise was self-reported. We do not know if similar changes in infant HR and HRV occur from an exercise intervention in women that were sedentary prior to pregnancy. This study will address this gap. The purpose of this study is to determine if exercise during pregnancy is the main influence of one-month-old infant heart rate (HR) and HR variability (HRV), regardless of physical activity habits before pregnancy. We hypothesized that exercise during pregnancy is the most significant predictor of lower infant heart rate and increased heart rate variability, regardless of exercise prior to pregnancy. Participants performed a minimum of 150 minutes of moderate intensity aerobic activity (40-59% heart rate reserve [HRR]) through three 50 minute sessions per week starting at 16 weeks gestational age (GA) through birth. Controls were received no exercise intervention. Participants completed an activity questionnaire to determine activity level prior to pregnancy. Heart rate (HR) and heart rate variability (HRV) were recorded in infants one-month after birth. Measures of HRV included for analysis were SDNN, RMSSD, Total Power, VLF, LF, HF, and LF:HF ratio, which are representative of improved sympathetic, parasympathetic, and overall autonomic development. Participants were analyzed using t-tests between active and inactive women before pregnancy, active and inactive women during pregnancy as well as using multiple ANOVAs between 4 groups: Active: Active (AA), Active: Inactive (AI), Inactive: Active (IA), and Inactive: Inactive (II). Statistical analyses also included correlations and multiple regression analyses. Participants (n=21) were similar in age, body mass index (BMI), and parity. There were 15 male and 6 female infants born. Infants of participants who were active during pregnancy had significantly lower average HR, and higher measures of SDNN and RMSSD (p=.02; p=.01, p=.02), respectively. Infants of participants whose mothers were inactive before pregnancy and active during pregnancy (IA) had lowest average heart rate of the four groups. Based on the updated exercise guidelines adopted by the American College of Sports Medicine (ACSM) from the American Congress of Obstetrics and Gynecology (ACOG), the results of this present study suggest that 1) Increased physical activity levels in women during pregnancy is associated with lower infant heart rates and higher markers of heart rate variability in comparison to those who did not exercise during pregnancy. 2) Participating in exercise during pregnancy when previously inactive can potentially yield greater benefit than just activity before pregnancy. 3) Increasing physical activity during pregnancy is correlated with lower infant heart rates and higher measures of heart rate variability. Our results provide support to continue or to begin a moderate intensity aerobic exercise program in low-risk pregnancies. Further research is needed, but this supports the notion that exercise during pregnancy may be one of the earliest interventions to improve infant heart health and decrease risk of heart disease.

Molecular biology
MicroRNAs (miRNAs) are a newly discovered class of endogenous post-transcriptional gene regulators that are typically 20-22 nucleotides in length that do not code for proteins. MiRNAs regulate gene expression by either inhibiting protein translation, or by targeting messenger RNAs (mRNAs) for cleavage. MiRNAs are highly evolutionarily conserved and have been found in many plants such as corn, soybeans, rice, and Arabidopsis. Nicotiana tabacum, or cultivated tobacco, is an important economic, agricultural, and research crop that provided approximately $4.4 billion dollars to the United States economy in 2007. Although much genetic research has already been dedicated to tobacco, hardly any research regarding the role of miRNAs has been performed. In this project, the primary objective was to provide a functional analysis of miRNAs in Nicotiana tabacum. First, the expression profiles of miRNAs and their targets were generated for different organs through the use of quantitative real time PCR (qRT-PCR). It was found that all the miRNAs and targets that were tested were differentially expressed throughout different tissue types in tobacco. In particular, miR159 was found to be expressed the highest in all tissue types tested. Secondly, very few reference gene analyses have been performed in tobacco, therefore a reference gene analysis in tobacco was conducted. In this analysis, 12 housekeeping genes were tested for their effectiveness in serving as reference genes for gene expression analyses in tobacco. QRT-PCR was used to quantify the amount of expression of each candidate reference gene, and a new comprehensive reference gene analysis tool, RefFinder, was used to rank the candidate reference genes based on the stability of their expression. The housekeeping genes that show the least amount of variability in expression were deemed appropriate reference genes for use. Through the use of RefFinder, GAPDH (glyceraldehyde 3-phosphate dehydrogenase) and PP2A (protein phosphatase 2A) were identified as being the most relaible reference genes for use in tobacco gene expression studies. Finally, microRNAs have been identified that mediate stress responses in plants to abiotic factors, but there have been few studies conducted on the effects nanoparticles may have on tobacco growth, development, and microRNA expression. To study this, tobacco seedlings were exposed to varying concentrations of aluminum oxide nanoparticles and tested to see which miRNAs were significantly changed in expression. It was found that the growth and development of tobacco seedlings was significantly adversely affected by increasing concentrations of aluminum oxide nanoparticles. In addition, several miRNAs were identified that may play a significant role in mediating plant responses to nanoparticles stress due to the magnitude of up regulation in expression. Overall, by providing a functional analysis of miRNAs in tobacco, these results will further help scientists to understand how plants react to their environment and will allow the further use of miRNA-mediated biotechnology to further improve crop yield and quality.

This research study looks to determine the varying quality of election coverage in democratic nations. Articles from USA Today and The New York Times that covered the 2012 presidential election were used to study media quality in the United States, The Daily Telegraph and The Guardian provided coverage of the 2010 British election, and The National Post and The Globe and Mail were used to examine coverage of the 2011 Canadian election. The articles chosen from these newspapers provided election coverage from one month before the respective election days. A comprehensive list of terms and phrases denoting high or low quality media coverage was used to compare the quality of the newspapers from each nation. The findings of this research showed that Canada had the highest quality media while Great Britain had the lowest. All three countries had similar percentages for low quality terms.

This thesis examines the complex nature of the poetic genre of the dramatic monologue by providing multiple perspectives on the genre--namely, those of the literary critic and the creative writer. This thesis provides a selection of original dramatic monologues in various styles and featuring characters ranging from the prophet Jeremiah to a modern-day plastic surgeon, tied together by the theme of imaginatively filling in historical gaps and erasures with speakers in times of great political or cultural upheaval. Prefacing this collection of poems is a discussion of the genre of dramatic monologue, beginning with a general overview of the development and features of the genre, followed by a discussion of specific issues involved in writing this collection. Â

Development of Computational Tools and Resources for Cotton microRNA Analysis

MicroRNAs (miRNAs) are an extensive class of small regulatory RNAs which regulate gene expression at the posttranscriptional levels. miRNAs target genes for mRNA cleavage or translation inhibition based on the complementary between the mRNAs and its corresponding miRNAs, and these miRNA target genes control development timing, organ development and response to environmental stress; thus miRNAs have been shown to play important roles in almost all biological and metabolic processes. Upland cotton (Gossypium hirsutum L.), one of the most important fiber producing crops, is widely planted in the world. Upland cotton originated from the reunion of two ancestral cotton genomes (A and D genomes) approximately 1-2 Myr ago, owning a complicated genome of allotetraploid (AADD, 2n=4x=52), with a haploid genome size estimated to be around 2.5 Gb. To date, about 80 miRNAs have been subsequentially identified in cotton by computational prediction or small RNA sequencing, many of which were also shown to be expressed differentially during fiber development. However, although miRNA-related research has become one of the hottest research in biology in the past decade and thousands of miRNAs have been identified, miRNA-related research in cotton is far beyond other plant species. One of the major reason is because of limited computational tools and resources for cotton. In this dissertation project, we first developed a comprehensive computational tool named miRDeepFinder, which can be used for miRNA identification, target prediction and GO-/KEGG-based functional analysis for both model and non-model plant species. A case study with a small RNA sequencing data of Arabidopsis showed miRDeepFinder is an accurate and robust tool for plant miRNA analysis in deep sequencing, since 12 of 13 novel miRNAs in Arabidopsis identified by miRDeepFinder were further confirmed by qRT-PCR. miRDeepFinder also incorporated the popularly-used Cleaveland software package for analysis of degradome sequencing data. Although cotton genome is still not available, huge cotton ESTs could be a good data resource for identification of cotton miRNAs and their targets. To better utilize cotton ESTs for miRNA identification, we globally re-assembled all the cotton ESTs and developed it to a cotton EST database, in which cotton coding genes and miRNAs were deeply annotated using BLASTx, BLASTn, Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) resources. A total of 28,432 unique contigs were assembled from all 268,786 cotton ESTs currently available, belonging into 5,461 groups with a maximum cluster size of 196 members. Using these contigs, we also performed EST-based investigations of comparative transcriptome similarity between cotton and other plant species, sequence polymorphisms, expressed miRNAs and their targets, and SSR analysis. A total of 27,956 indel mutants and 149,616 single nucleotide polymorphisms (SNPs) were identified from consensus contigs. In a comparison with six model plant species, cotton ESTs show the highest overall similarity to grape. We also identified 151 and 4,214 EST-simple sequence repeats (SSRs) from contigs and raw ESTs respectively. Finally, all results were integrated to a comprehensive web-based cotton EST database (www.leonxie.com), in order to make these data widely available, and to facilitate access to EST-related genetic information. Subsequently, 3 cotton small RNA sequencing libraries treated by control, drought and salinity were sequenced. Based on miRDeepFinder, annotated cotton EST database, and cotton D genome of Gossypium raimondii, we identified 337 miRNAs with precursors in total, including 289 known miRNAs and 48 novel miRNAs. 155 of 337 miRNAs were found to be expressed differentially amongst the three treatments. Target prediction, GO-based functional classification, and KEGG-based functional enrichment uncovered many miRNAs and their stress-related targets might play roles in response to salinity and drought stresses. Using CitationRank-based literature mining, we sorted out the importance of genes related to stress of drought and salinity, respectively. It turned out NAC family, MYB family and MAPK family were ranked top under the context of drought and salinity, indicating their important roles for plant to combat stress of drought and salinity. To identify potential miRNAs and mRNA genes that significantly contribute to cotton fiber development, we constructed two libraries of 1-DPA (days post anthesis)-old leaf and ovule and sequenced them. A total of 128 pre-miRNAs, including 120 conserved and 8 novel pre-miRNAs were identified in cotton by miRDeepFinder. At least 40 miRNAs were either leaf or ovule-specific, whereas 62 miRNAs were shared in both leaf and ovule. Many transcription factors and other genes important for development of fiber were predicted to be miRNA targets. 22 predicted miRNA-target pairs were further validated by degradome sequencing analysis. In addition to miRNAs, we also identified 11 potential tasiRNAs-derived genes, many of which also might be involved in fiber development. miRNAs from cotton A and D genomes that reunioned together ~1-2 Myr ago might experience similar evolution pattern with coding genes. However, little is known about miRNA origin, expansion, loss, duplication, whether different derived miRNAs exchange with or affect each other, and how different genome-derived miRNAs and different genome-derived coding gene interact in cotton. To this, we systematically investigated miRNA expansion, expression pattern, miRNA targets amongst three cotton species Gossypium hirsutum (AADD), Gossypium arboreum (AA), Gossypium raimondii (DD). The origin of miRNAs and coding genes were the first to be categorized in upland cotton. Our results also showed that cotton-specific miRNAs might undergo remarkably expansion and some highly conserved miRNAs were likely to be lost despite most of conserved miRNAs were remained after genome polyploidization. The comparison of miRNA expression during seedling and fiber at 5 developmental stages revealed that different genome-derived miRNAs and miRNA*s displayed asymmetric expression pattern, implicating their diverse function in upland cotton phenotype. Upon all the identified miRNAs identified in upland cotton above, we also globally investigated miRNA modification features in cotton. Besides the observation of some similar modification features with other plant species in cotton, we also found many interesting modification forms, such as modification balance between 5' and 3' end miRNAs. Comparison of isomiR expression shows differential miRNA modification amongst the 6 developmental stages in terms of selective modification form, development-dependent modification, and differential expression abundance. In contrast to previous reports, cytodine is more frequently truncated and tailed from the two ends of isomiRs in cotton, implying existence of a complex cytodine balance in isomiRs. Together, we developed a comprehensive computational tool and data resource for cotton miRNA research, and used these tools to investigate miRNA roles in cotton fiber development and response to abiotic stress. Cotton miRNA evolution and modification were also studied. Thus, our tools, data resources and research findings would contribute us to deciphering miRNA regulatory function and evolution in cotton.

Targeting Psychological Flexibility in Youth to Enhance Health-Related Behaviors
Faulkner, Samuel A.
Golden, Jeannie
Psychology
Psychological Flexibility
Background: Adolescents are uniquely vulnerable to a wide range of psychological issues and often, concerns inadequately addressed. When addressed, mental health concerns are commonly handled in schools, which are uniquely positioned to prevent social and emotional difficulties. Universal, social and emotional learning curricula have demonstrated efficacy within a framework providing multi-tiered systems of support and represent promising methods for addressing youth mental health with a broad scope. Unfortunately, implementation of social emotional learning curricula presents multiple barriers to implementation and limited understanding of the processes of change, necessary procedures, relevant contextual variables, and differential impact of curricula on positive student functioning with high school students. Traditional models used to address mental health in adolescents often take a deficit-oriented approach. An emerging developmental model of behavior change incorporates principles of Acceptance and Commitment Therapy, Positive Psychology, Behaviorism, Relational Frame Theory, and Evolution Science to target functional classes of behavior and facilitate health-promoting behaviors in youth. Purpose: The present study is a preliminary investigation examining the feasibility, acceptability, efficacy, participant characteristics (e.g., trait mindfulness), and processes of change (e.g., psychological inflexibility) associated with a universal preventive intervention based on a process-oriented, developmental model of behavior change targeting health-promoting behaviors. Method: Students (n = 118) were recruited from 6 Health/PE classes in a rural, underserved high school. The participant sample consisted of 48% African-American/Black, 27% Hispanic/Latino, 22% Caucasian/White, and 3% American Indian/Native American. Almost all (i.e., 96%) of participants reported receiving free or reduced lunch. Participants were assigned to an enhanced Health/PE condition or a comparison condition. Participants in the enhanced Health/PE condition received 6 weeks of a universal preventive intervention targeting social and emotional learning skills, sleep, and physical activity. Results: The enhanced Health/PE curriculum was feasibly implemented with satisfaction from students and teachers. Participants in the enhanced curriculum did not exhibit significant changes in psychological inflexibility, sleep hygiene, or physical activity from baseline to post-intervention; however, changes in amount of time engaging in physical activity were present at one-year follow-up relative to the comparison condition. Trait mindfulness did not moderate the relationship between condition assignment and treatment outcomes. Psychological inflexibility did not mediate the relationship between condition assignment and health-related outcomes. Post-hoc analyses indicated no significant differences between pre- and post-test psychological inflexibility scores for students with clinically significant ratings. Due to a relatively small number of participants (n = 14) meeting the clinically significant cutoff on the AFQY-8 (total score of at least 15), post hoc analyses of these participants were conducted to determine potential differential impact from programming. Nine participants in the DNA-v-PE condition and four in the comparison condition exhibited clinically significant ratings of psychological inflexibility at baseline. Independent samples t-tests were conducted to compare pre- and post-scores of psychological inflexibility for both groups. Participant pre-test scores (M = 17.79, SD = 2.99) did not differ significantly from post-test scores (M = 13.15, SD = 8.55), t(25) = 1.91, p = .07, d = .73, 95% CI [-.05, 1.51). Pre and post scores were also compared within conditions. DNA-v-PE participants pre-test scores (M = 17.56, SD = .82) did not differ significantly from post-test scores (M = 14.44, SD = 9.29), t(16) = .97, p = .35, d = .46, 95% CI [-.49, 1.39]. Comparison condition participants pre-test scores (M = 18.2, SD = 1.83) did not differ significantly from post-test scores (M = 10.25, SD = 6.8), t(7) = 2.19, p = .07, d = 1.47, 95% CI [-.09, 2.94). Results indicate both conditions exhibited non-significant reductions in psychological inflexibility from baseline to post-intervention. Notably, although there were non-significant changes in scores for participants in the either condition, changes were associated with a large effect (i.e., Cohen's d > .8) in the comparison condition and a small to medium effect in the DNA-v-PE condition. Discussion: Findings were reviewed in the context of research and clinical implications of process-oriented, social and emotional learning curricula and the importance of evaluating contextual variables, and moderators and mediators of treatment. Practical implications of conducting universal preventive interventions in schools and limitations of the current study are discussed.

THE LIVED EXPERIENCES OF AFRICAN AMERICAN PUBLIC UNIVERSITY DEVELOPMENT ADMINISTRATORS
Prince, T. Greg
Siegel, David J., d1966-
Educational Leadership
University Development
Diversity
African Americans
This study explores the lived career experiences of African American university development administrators who work at public higher education institutions. In a society that is growing increasingly ethnically diverse, among other ways, and where college graduates reflect this increased diversity, it is important that research is conducted concerning ethnic minorities and members of traditionally marginalized groups who serve within the profession of university development.
The purpose of this research was to explore career experiences, with particular attention to recruitment, engagement, and retention factors, as well as participants’ perceptions of efficacy regarding these efforts. Five participants were selected for this study with the following characteristics: they all have served within the field of university development for 10 years or longer and have had more than one employer during their careers. Participants represented a range of ages (30s through 50s) and were diverse in terms of gender (three males, two females). Collectively, the five participants had experience working at predominantly White institutions, HBCUs, and predominantly Hispanic institutions.
This qualitative study utilized the narrative research tradition. Jerlando Jackson's ERA model was used as the theoretical framework and provided a guide to inquiry. Interviews with selected participants led to six emerging themes: (1) the pipeline into the profession; (2) on-boarding and investment; (3) respect leads to loyalty; (4) achieving an all-important balance; (5) career challenges related to personal demographics; (6) personal considerations and relational/family issues.
Recommendations for future research included performing research with other ethnic groups, with multi-racial participants, with other traditionally marginalized groups, and with Whites who work at non-predominantly White institutions. The potential benefit of structured entry-level opportunities (ex: internships; graduate assistantships targeting underrepresented groups in certain areas such as marketing and sales, journalism and public relations), as well as opportunities for those who “self-select� and work in development offices as undergraduate students could prove beneficial. The administrator would benefit in terms of recruiting and the academy would benefit by potentially expanding current academic offerings where there is a documented need, thus effectively bridging the gap between practitioners and academics.

The Boys & Girls Club services children ages 6 to 18 with programs and activities that emphasize development strategies (BGCA, n.d.). It provides role models, a safe environment, and constructive activities that focus on overall health. The club depends heavily on community engagement in the form of donors, partnerships, and volunteers (BGCA, n.d.). Our local club provided programs focusing on financial responsibility, leadership, and mental health, but lacked development of physical health practices. Kids Run the World comprised various activities to promote physical health in adolescents. This program is led by college level volunteers that worked with elementary and middle school-aged children to show them fun and safe ways to exercise. Before implementation of the program, research was completed to understand the dynamics of the local Boys & Girls Club. This research included how to be an effective role model and successes of similar programs. This is when “Kid Run the World� was established and put into action. After volunteering at the Boys & Girls Club throughout the duration of our project, we have observed increased physical activity levels and overall morale when group members and athletes are there leading activities. This was successful because of consistent attendance and positive interactions with the children. We learned we needed to have a youthful perspective and engage the kids with exercises they found familiar. Despite COVID-19, our group continues to make efforts to engage youth through our organization on campus, Kids Run the World. The Boys & Girls Club has many underserved children, and this has provided our group with a unique platform that has benefited both us and the children through increased physical activity levels and community involvement.

Genetic regulation of maize floral development - insights from the transcriptome and translatome
Yang, Hailong
Thompson, Beth
Biology
Ables, Elizabeth
Keiper, Brett
Anderson, Eric
Horn, Patrick
Maize
Flower development
Transcriptome
Translatome
Flowers are produced by floral meristems, groups of stem cells that give rise to floral organs. In grasses, including the major cereal crops, flowers (florets) are contained in spikelets, which contain one to many florets, depending on the species. Floral development in plants is regulated by gene expression. Understanding gene expression regulation in maize floral development is critical to regulate floret fertility in other grasses and potentially useful to engineer more productive cereal crops.
In this work, I focus on gene expression regulation at transcriptome and translatome level to gain insights into floral development. To transcriptionally gain insight into the functional differences between florets with different fates, I examined gene expression in upper and lower floral meristems in maize ear using laser capture microdissection coupled with RNA sequencing. Differentially expressed genes were involved in hormone regulation, cell wall, sugar and energy homeostasis. Furthermore, cell wall modifications and sugar accumulation differed between the upper and lower florets. Finally, a novel boundary domain between upper and lower florets was identified, which might be important for floral meristem activity. A model is proposed, in which growth is suppressed in the lower floret by limiting sugar availability and upregulating genes involved in growth repression.
To gain insight into microRNA regulation in maize floral development, I examined the translatome of a maize microRNA biogenesis mutant and normal siblings using ribosome profiling and RNA sequencing. My results indicated microRNAs in maize regulate both mRNA decay and translation repression. Importantly, translation repression by microRNAs is broad but magnitude is small in maize. Furthermore, translation is broadly affected beyond direct microRNA targets when microRNAs are perturbed. Thus, translation regulation is likely a critical regulator gene expression during floral development.

Skin Carotenoid Levels
Preschool Aged Children
Head Start
Veggie Meter®
Objective: Examine differences in skin carotenoid levels (SCL) based on time, age, sex, and race of preschool-aged children (PSAC) enrolled in Head Start (HS) in North Carolina (NC). Design: Data were collected using surveys from participating families. PSAC's SCL were measured 3 times over a 6-month period. Setting: 3 HS centers in NC Participants: 112 children aged 3-5 years old, enrolled in HS Main Outcome Measure(s): Differences in SCL assessed using the Veggie Meter[registered] based on time, sex, race, and age Analysis: Analysis of Variance (ANOVA) with a Greenhouse-Geisser correction to assess SCL at Time 1 between sex, race, and age (n=112). Repeated measures ANOVA to assess SCL over time (n=45) using Bonferroni correction(b). Results: On average, children were 4 years old, African American (81.3%), male (57%) and mean SCL 266 (SD 82.9). SCL were significantly different over time (p[less-than].001). Significant differences were observed between ages (p=.01) and sex (p=.01), but not between race. Conclusions and Implications: The Veggie Meter[registered] is a promising tool to assess fruit and vegetable intake but needs to be validated in PSAC as has in adults. Sex, age, and race are potential confounders which should be assessed in future studies using the Veggie Meter[registered].

FORT BRANCH, HAMILTON COUNTY, NORTH CAROLINA: RESEARCH DESIGN AND SITE MANAGEMENT PLAN
Heinrich, Keith T.
Ewen, Charles R., 1956-
Anthropology
The purpose of this thesis is to produce a research design and a site management
plan for Fort Branch, a National Register-listed Confederate earthwork on Rainbow Bend
in Martin County, North Carolina. The thesis discusses the history of Fort Branch,
starting with a history of the Civil War in eastern North Carolina, to provide a context for
the fort’s construction. A specific history of the fort discusses the defenses of Rainbow
Bend and their eventual evolution into what is now Fort Branch. The research design
uses the historical and archaeological background to formulate site-specific
archaeological questions and uses case studies of Civil War archaeology to ensure that
research at Fort Branch is placed within the context of Civil War archaeology. Previous
archaeology, the archaeology of fort construction, an archaeological survey of the site,
the archaeology of skirmishes, the archaeology of encampment, landscape studies, and
the historic cemetery are discussed in this thesis. This research is important because it
will provide the Fort Branch Battlefield Commission with ways to better interpret the
battlefield, enhance its mission of preservation and restoration, and provide ways that the
site can be protected for future generations.

Exposure Control and Process Safety Of Monomers in Selected Plastics and Rubber Industries
Kearney, Kevin M.
rubber, plastics, monomers, exposure control
A review of the literature of monomers was conducted that incorporates polymer science and contemporary toxicology and epidemiology studies associated with their exposures. This review, supplemented with a history of monomer exposure control technologies and protocols, helped establish the basis for a questionnaire created to ascertain and examine best practices in process safety. This questionnaire, in the form of interviews, open discussions, and detailed entries, was employed to identify common themes applicable for consensus guidelines in the chemical industry. Environmental Health and Safety (EHS) professionals, including safety engineers and industrial hygienists, were recruited from a range of chemical companies that use monomers to produce plastics and rubbers. Among the observations by these professionals was the recognition of professional discipline as a key motivator of EHS best practices, especially during routine evaluation and implementation of safety programs. Another main observation was the importance of advancing worker and contactor training, in tandem with the retention of highly qualified workers. Results of this study suggested that progress in EHS may be inhibited by redundancies in safety programs, challenges in achieving zero incident targets, and requirements for third-party stewardship programs. Additionally, the commercial availability and support of state-of-the-art engineering controls and cooperation of experts within professional and trade associations were found to be major drivers in process safety. It is therefore crucial that regulatory directives and standards concerning polymer production are reevaluated, updated, and repurposed to provide flexibility in achieving compliance and risk prioritization.

Solvent-Controlled Switch of Selectivity between sp[superscript]2 and s[superscript]p3 C-H Bond Activation by Platinum (II)
Garner, Alexander William
Huo, Shouquan
Chemistry
Chemistry
Cyclometalation reactions have been studied intensely for the past few decades, especially those containing palladium. The factors that control the process of the C-H bond activation, however, are not yet completely understood. C-H bonds are ever-present in organic molecules, but the vast majority of them cannot be exploited for chemical reactions due to their inert and stable nature. Early attempts to activate these bonds led to very complicated mixtures of products, and therefore not an acceptable means of C-H activation due to poor selectivity. Controlling the selectivity of a reaction is one of the most important issues surrounding synthetic chemistry. It is generally recognized that aromatic C-H bonds are more likely to undergo activation by platinum complexes. However, recently it has been illustrated that there is a delicate balance between sp[superscript]2 and sp[superscript]3 C-H bond activation in a platinum (II) complex system.       In this study, the solvent-controlled switch of selectivity between sp[superscript]2 and sp[superscript]3 C-H bond activation in platinum (II) complex systems will be discussed. Ligands L1 through L3 were designed and synthesized to test the selectivity of cycloplatination of a reaction with potassium tetrachloroplatinate (II) in two different solvents, acetonitrile and glacial acetic acid. It was found that in each of the solvents used, a different isomer was produced from the complexation reaction. Reactions of L1 through L3 with potassium tetrachloroplatinate (II) in acetonitrile produced the sp[superscript]2 substituted isomer (1B-3B), while the same reaction performed in glacial acetic acid formed the sp[superscript]3 substituted isomer (1A-3A). It was determined through mechanistic studies that the sp[superscript]2 substituted isomer is a kinetically controlled product, while the sp[superscript]3 substituted isomer is a thermodynamically controlled product. Also, it was found that the ratio of products depends on time, where as more time goes by the thermodynamically stable product begins to predominate.   Other issues examined in this study were the side reactions that occurred during the complexation of ligands L2 and L3. These side products were due to C-C bond cleavage in L2 and C-N bond cleavage in L3. These side products were characterized and studied in their own right. Â

The Contour of Developmental Music: Analog of the Plot Diagram
Bellardini, Nick
Taggart, Mark
Music
Musical narrative
classical music
jazz music
In my studies in music, I have always found the programmatic aspect to be powerful. Within my music, I always strive for a programmatic aspect, tying in motifs to stage stories or recall past events. Overall, the driving force of music provides, in many cases, an analog for a plot contour commonly found in stories. In this recital, two pieces stylistically do not lend themselves to plot contours, while the capstone Classical pieces both demonstrate a climax through development, using recurring themes. While music is not necessarily definitive in its programmatic capabilities, the final work is intentionally defined by its narrative. The wordless styles of music carry followable patterns that in essence describe characters. With repetition in music, these abstract “characters� go through syntactic developments akin to a story.

Just keep clicking Till You Find It: Building a Library Digital Collection Interface with Browsing in Mind
Gueguen, Gretchen
Digital libraries
Interface design
This session will explore how East Carolina University's Joyner Library developed an interface to their digitized special collections to facilitate user browsing. The library's digital collections contain thousands of items digitized from hundreds of collections – in some cases only one or two items are digitized from a collection. This hodge-podge approach is a result of the library's image management practices which attempt to store materials digitized on a daily basis (for patron requests, preservation concerns, publication or exhibits, etc.) into the publicly available digital repository.
As the repository was being developed, the staff of Joyner Library decided that the traditional approach to presenting digitized special collections materials as a sort of online "exhibit" where materials are selected to illustrate a theme or to systematically convert an entire collection to the digital format would not work. Instead, the staff experimented with different ways to enhance user browsing through materials. They looked to the world of commercial websites, next generation catalog interfaces, and social networking sites to develop a suite of navigation tools that enhance serendipitous discovery using their own home-grown solutions that are built on top of an SQL database and an XML database. The final collection interface includes: broad thematic "collections", "tag cloud"-style navigation, and a faceted-browsing refinement tool, all developed from cataloguer-created subject headings; hyperlinked terms in item records to facilitate broadening searches; links back and forth between collection finding aids and other digital resources at the library; user commenting and tagging of resources to begin to integrate emerging folksonomies.
The session will describe the technologies and techniques used to develop these tools, examine some of the benefits and drawbacks to this approach, and discuss user feedback collected through usability testing, website statistics, and reference interaction.

Language is the vehicle through which we express ourselves and interact with the people and places around us. Language shapes our identity within the varied communities in which we belong. Translanguaging is a concept that recognizes the importance of all languages and breaks down the political, social, and linguistic barriers to expression and learning through language. In this dissertation, working with a team of co-practitioner researchers at a school in Chiang Mai, Thailand, we reflected on our language experiences and our roles as educators in addressing how to best support multilingual learners in Kindergarten and Grade 1. I explored how the collaborative relationship of elementary school teachers can promote the development of multiple languages and negotiate the external pressures that impact language in schools.Two findings include: (1) Instructional assistants play a pivotal role in empowering multilingual language learners by creating safe spaces for learning that empowered students; and (2) Teachers and instructional assistants use emergent translanguaging practices that inform the school policy on language use. As co-teachers in multilingual language learning who used components of emergent translanguaging practices, the teachers recognized the value of leveraging each student’s languages for learning. They designed and implemented instructional plans to respond to students’ linguistic needs (GarcÃa, 2009).
The implications of this study include empowering multilingual learners to fully access the curriculum by providing them with opportunities to use their known languages for learning. Additionally, instructional assistants, who are often overlooked as classroom assets, can provide important instructional and linguistic expertise to multilingual learners by understanding the
needs of multilingual learners and integrating language and instruction.

Skeletal muscles undergoing atrophy have decreased [ATP], PGC-1[alpha] expression, and mitochondrial content. This combination of findings is unexpected because decreased [ATP] is often associated with greater [AMP] and subsequent activation of AMPK, a known inducer of PGC-1[alpha] activity and mitochondrial biogenesis. A possible explanation is increased enzyme activity of AMP Deaminase 3 (AMP [rightwards arrow] IMP + NH3), which is highly overexpressed in atrophic muscles and functions to prevent increases in [AMP]. We tested the hypothesis that AMPD3 overexpression would significantly attenuate DNP (mitochondria uncoupler) induced phosphorylation of AMPK(Thr172) and PGC-1[alpha] promotor activity through regulation of intracellular energetics (ATP, ADP, AMP). Methods: Myotubes were transduced with adenoviruses encoding AMPD3 or GFP (control) and then treated for 1 h with 0.6mM 2,4 dinitrophenol (DNP). Nucleotides, amino acids, and proteins were extracted immediately after DNP treatment and measured by UPLC and Western Blot. To confirm DNP was not toxic, myotubes were washed, and samples were collected 1 h later for nucleotides and amino acids. To determine the effect of AMPD3 overexpression on PGC-1[alpha] promotor activity we transfected myoblasts with a 2kb PGC-1[alpha] promotor-luciferase reporter plasmid. After 5 days of AMPD3 or GFP overexpression and a 4-day 100[mu]M DNP treatment, we measured luciferase activity. We also stained myotubes for mitochondria using a green fluorescent dye (MitoTracker green FM) and quantified the percentage of pixels positive for florescence. Results: DNP treatment resulted in a 40% decline in [ATP], and increased [ADP] (1.4-fold), [AMP] (13.8-fold), AMP:ATP ratio (24-fold), and [IMP] (from undetectable) (p<0.001). DNP treatment also significantly increased phosphorylated AMPK(Thr172) (6.1-fold), and phosphorylation of downstream AMPK targets, ACC (Ser79, 4.8-fold) and ULK1 (Ser555, 2-fold) (p<0.001). Aspartic acid levels increased 7.1-fold (p<0.001), suggesting decreased activity of the purine nucleotide cycle (IMP + aspartic acid [rightwards arrow][rightwards arrow] AMP). As expected, myotubes that were overexpressing AMPD3 had significantly attenuated increases in [ADP] (1.1-fold), [AMP] (5.3-fold), and the AMP:ATP ratio (9.6-fold) (p<0.001), and this was reflected by significantly less phosphorylated AMPK(Thr172) (p<0.05). No changes were measured in aspartic acid or phosphorylation of ACC(Ser79) and ULK1(Ser555) between myotubes overexpressing AMPD3 versus GFP. After a 1 h recovery [AMP], AMP:ATP ratio, and [aspartic acid] were no different than vehicle treated, demonstrating recovery of energetics and cell viability. Long-term treatment with DNP significantly increased PGC-1[alpha] promotor activity (1.4-fold, p<0.001) compared to vehicle groups, while 5 days of AMPD3 overexpression significantly decreased PGC-1[alpha] promotor activity (1.3-fold, p<0.005) compared to GFP. Long-term DNP treatment increased the percentage of pixels positive for green florescence (p<0.05), however, myotubes overexpressing AMPD3 had significantly less than controls (p<0.01). Conclusions: Since activation of AMPK and PGC-1[alpha] are critical for increasing mitochondrial biogenesis, our results suggest that overexpression of AMPD3, such as occurs during muscle atrophy, is an important contributor to reductions in mitochondrial content.

DOSIMETRIC STUDY OF BETA-MINUS EMITTER PRASEODYMIUM-142 : APPLICATIONS IN MICROSPHERE BRACHYTHERAPY FOR HEPATOCELLULAR CARCINOMA AND BRACHYTHERAPY FOR OCULAR SQUAMOUS CELL CARCINOMA

A dosimetric study of the beta-minus emitter Praseodymium-142 (¹�²Pr) was performed and two main innovative applications of this source in brachytherapy are proposed: microsphere brachytherapy and eye plaque brachytherapy. ¹�²Pr (96.3% beta and 3.7% gamma) has recently gained increased attention among beta sources for therapy. Its inherent physical and dosimetric characteristics may be suitable for several brachytherapy applications. This relatively short halflife (19.12 h) allows this source to deliver high dose rates to the target. Penetration of the beta component of ¹�²Pr radiation in tissue is limited to a few millimeters, therefore limiting dose deposition to the treated site. The large neutron activation cross-section of the parent isotope (11.40 barn including that of a meta-stable state) allows the activation of this nuclide in a low neutron fluence reactor, making its production easily available for both research and therapy purposes. From simulations and measurement of the doses, exposure rates due to the 3.7% gamma component showed to be clinically small for the patients' healthy organs and tissues as well as to medical staff and general public. Furthermore, it was studied whether its gamma component could be effective in performing pre-treatment quality assurance (QA) and dosimetry, as well as post-treatment biodistribution imaging and dose distributions of permanently implanted ¹�²Pr brachytherapy sources. Two main novel applications of ¹�²Pr beta emitters are studied in this work: (i) ¹�²Pr glass microspheres, as a possible choice of radionuclide for microsphere brachytherapy of nonresectable hepatocellular carcinoma (HCC) and metastasis of the liver, and (ii) ¹�²Pr glass rods for brachytherapy of ocular squamous cell carcinoma (OSCC), based on a novel design for eye brachytherapy -- also developed in this work. In order to simulate the dosimetric characteristics of ¹�²Pr, MCNPX2.6 Monte Carlo code and BRAIN-DOSE Dose Point Kernel code were used to determine the dose distributions of ¹�²Pr for different source distributions. Dosimetric properties of the currently used nuclide in microsphere brachytherapy, Yttrium-90 (��Y), was also studied and compared to ¹�²Pr. A more realistic biodistribution model of microspheres within a single HCCs blood vessel was studied. In addition, the biological effective dose (BED) for different tumor doubling times (DT) for HCC was determined using the linear quadratic (LQ) model for both nuclides. Dose distributions for ¹�²Pr, ��Y and Rhenium-188 were simulated within the eyeball and compared for application in eye brachytherapy. Measurements of dose distribution using GAFCHROMIC® EBT2 film were performed with ¹�²Pr glass microspheres and ¹�²Pr glass rods. Monte Carlo simulation validation with experimental measurements in phantom of the dose distribution due to ¹�²Pr glass microspheres and ¹�²Pr glass rods were performed. ¹�²Pr showed to be a possible choice of radionuclide for HCC microsphere brachytherapy and OSCC brachytherapy, delivering a high biological effective dose, and opening possibilities for post treatment imaging and biodistribution assessment.

The NIH Mandate One Year On: How Are Libraries Responding?
Thomas, William Joseph
National Institutes of Health
NIH mandate
Open access
Public access policy
About one year ago, the landmark National Institutes of Health Public Access Policy began requiring authors who receive NIH funding to deposit final versions of their accepted manuscripts to NIH’s PubMed Central database. These papers would then become freely available to the public no later than 12 months after publication. How are academic libraries responding? Results of a survey will be complemented by interviews with selected librarians to provide insights into who’s doing what, and how successful these libraries feel they have been.

Listening to the most important voice in teacher education: The voice of the teacher candidate
Steadman, Sharilyn
Lys, Diana B
The conversation surrounding the current state of public education in America has become increasingly
negative and harsh. The focus of that criticism is often directed at funding issues, charter schools,
vouchers, graduation rates, political agendas...and teachers themselves. Understandably, in an effort to
address concerns about the quality of teachers, notably new graduates, colleges of education are
implementing new programs, new forms of assessment, new forms of student teaching internships, and
other reforms. In their attempts to improve teacher quality, however, teacher educators can learn much
about the impact of their efforts by listening to the voices of those most closely affected by those changes:
their teacher candidates. This study examines what one university learned when they asked for and
listened to their new graduates feedback.
