(2011-12-01)Department: PsychologyThis dissertation takes a detailed look at two seemingly well-established procedures in Monte Carlo research. Part I closely examines the 3rd and 5th order polynomial transforms and the g-and-h distribution, all designed ...
-
(2016-09-22)Department: Biomedical EngineeringMagnetization transfer (MT) imaging has emerged as a viable alternative to conventional structural MRI indices. It has been shown to be remarkably sensitive to changes in myelin associated with pathologies such as multiple ...
-
(Vanderbilt University, 2024-04-12)Prosocial behavior is defined as any voluntary social behavior performed to benefit others. While many studies have found that prosocial behavior protects against depressive symptoms and negative emotions, few have ...
-
(Vanderbilt University, 2024)Dispositional accommodative efficacy (DAE) is the general belief in one’s ability to adjust to an unwanted or unchangeable situation. Previous research has shown that this efficacy has a strong, positive relationship to ...
-
(2023-03-14)Department: Chemical & Physical BiologyMicrotubules and actin filaments coordinate to remodel the cytoskeleton to facilitate proper cell migration. The coordination between microtubules and actin filaments are regulated by 1) chemical signals and 2) physical ...
-
(2018-07-06)Department: Earth and Environmental SciencesUngulates regulate important processes within their ecosystems, however their impact on nitrogen cycling remains unclear, and likely ecosystem and soil-specific. Much of the work examining the relationship has been in ...
-
(2014-07-16)Department: PharmacologySynaptic transmission is characterized by exocytotic events which mediate the release of chemical transmitters to facilitate neuronal communication. Inhibitory presynaptic GPCRs act as feedback regulators limiting transmitter ...
-
(2020-05-19)Department: NeuroscienceExcitatory signaling mediated by N-methyl-d-aspartate receptors (NMDARs) has been shown to regulate mood disorders. However, current treatments targeting NMDAR subtypes have shown limited success in treating patients, ...
-
(2023-11-16)Department: Cell & Developmental BiologyActin-based protrusions are found on the surface of all eukaryotic cells, where they support diverse biological activities essential for life. Models of protrusion growth hypothesize that actin filament assembly provides ...
-
(2017-05-26)Department: PharmacologyObsessive-compulsive disorder (OCD) is a chronic, disabling condition with inadequate treatment options that leave most patients with substantial residual symptoms. Structural, neurochemical, and behavioral findings point ...
-
(2007-12-06)Department: Biological SciencesIn most eukaryotes, telomere length is maintained by telomerase, a ribonucleoprotein that adds TG-rich telomeric repeats de novo to chromosome ends. Telomeric binding proteins (for example, Rap1p) affect telomere length ...
-
(2013-12-09)Department: Cell and Developmental BiologyDuring liver development, precise signaling is required to direct cell fate decisions and architectural establishment. It is hypothesized that the same signaling pathways are important in directing liver regeneration. To ...
-
(Royal Society Open Science, 2019-10)The influential triple-code model of number representation proposed that there are three distinct brain regions for three different numerical representations: verbal words, visual digits and abstract magnitudes. It was ...
-
(2009-01-15)Department: Biomedical EngineeringDiffusion tensor imaging (DTI) is a magnetic resonance imaging (MRI) technique that provides information about the organization and structural integrity of tissue. It has become an increasingly popular tool for investigation ...
-
(2010-12-07)Department: Human GeneticsNeither genome size nor gene number is indicative of organism complexity. Complex regulation of genes within a genome likely contributes to organism complexity. Coordinate regulation of genes through shared cis regulatory ...
-
(2007-04-04)Department: Molecular Physiology and BiophysicsTFIID is a multi-subunit protein complex that regulates activation of gene transcription. The coactivator model proposes that a given transcription factor activates transcription of its target gene by recruiting TFIID to ...
-
(2014-11-26)Department: Biomedical EngineeringIn this study, parameters for the clinical application of optical neural stimulation were developed. Two pulsed diode lasers, with wavelengths centered at 1875 nm and 1450 nm respectively, were used to elicit compound motor ...
-
(2022-05-12)Purpose: The long-term goal of this line of inquiry is to develop an ecologically valid and efficient measure of speech sound accuracy in connected speech that is suitable for use in clinical practice for children aged ...
-
(Vanderbilt University. Peabody College, 2016-04)This project is a one‐year investigation of the nature of academic supports afforded to limited English proficient students in the Jefferson County Public Schools district in Louisville, KY. Surveys, interviews, observations, ...
-
(2019-04-09)Department: Biomedical EngineeringPreterm birth (PTB) is the leading cause of death for children under 5, affecting 1 in 10 children in the United States. Premature infants are at a higher risk for infections and developmental issues. During pregnancy the ...
