Using screen video capture software to aide and inform cognitive interviewing
(2012-01-19)
Web-based surveys are a salient tool in the repertoire of social and behavioral scientists. The increase in web-based surveys is understandable considering the distinct advantages offered, including: (a) lower costs and ...
The cyclic-di-GMP signaling pathway in the Lyme disease spirochete, Borrelia burgdorferi
(2014-05-01)
In nature, the Lyme disease spirochete Borrelia burgdorferi cycles between the unrelated environments of the Ixodes tick vector and mammalian host. In order to survive transmission between hosts, B. burgdorferi must be ...
Pivotal Role of Adenosine Neurotransmission in Restless Legs Syndrome
(2018-01-08)
The symptomatology of Restless Legs Syndrome (RLS) includes periodic leg movements during sleep (PLMS), dysesthesias, and hyperarousal. Alterations in the dopaminergic system, a presynaptic hyperdopaminergic state, seem ...
The professionalism disconnect: Do entering residents identify yet participate in unprofessional behaviors?
(2014-03-27)
Background
Professionalism has been an important tenet of medical education, yet defining it is a challenge. Perceptions of professional behavior may vary by individual, medical specialty, demographic group and institution. ...
The home environment and childhood obesity in low-income households: Indirect effects via sleep duration and screen time
(2014-11-09)
Background: Childhood obesity disproportionally affects children from low-income households. With the aim of informing interventions, this study examined pathways through which the physical and social home environment may ...
Using the stable carbon and nitrogen isotope compositions of vervet monkeys (Chlorocebus pygerythrus) to examine questions in ethnoprimatology
(2014-07-10)
This study seeks to understand how humans impact the dietary patterns of eight free-ranging vervet monkey (Chlorocebus pygerythrus) groups in South Africa using stable isotope analysis. Vervets are omnivores that exploit ...
The potential role of magnetic resonance spectroscopy in image-guided radiotherapy
(2014-05-04)
Magnetic resonance spectroscopy (MRS) is a non-invasive technique to detect metabolites within the normal and tumoral tissues. The ability of MRS to diagnose areas of high metabolic activity linked to tumor cell proliferation ...
The evolution of land plants: A perspective from horizontal gene transfer
(2014-12-04)
Recent studies suggest that horizontal gene transfer (HGT) played a significant role in the evolution of eukaryotic lineages. We here review the mechanisms of HGT in plants and the importance of HGT in land plant evolution. ...
Using geometry to select one dimensional exponential families that are monotone likelihood ratio in the sample space, are weakly unimodal and can be parametrized by a measure of central tendency
(2014-07-18)
One dimensional exponential families on finite sample spaces are studied using the geometry of the simplex Δn°-1 and that of a transformation Vn-1 of its interior. This transformation is the natural parameter space ...
