C-Jun N-Terminal Kinase Signaling Guides The Migration Of Interneurons During Cortical Development, Abigail K. Myers Jan 2017

C-Jun N-Terminal Kinase Signaling Guides The Migration Of Interneurons During Cortical Development, Abigail K. Myers

Graduate Theses, Dissertations, and Problem Reports (ETD)

The cerebral cortex, responsible for higher order functions, is a layered structure that relies on the precise wiring of two main types of neurons, excitatory neurons and inhibitory interneurons. In order to maintain a critical balance of excitation and inhibition in the cortex, a smaller, yet very diverse, population of cortical interneurons provides inhibition to a much larger cohort of excitatory neurons. This makes interneurons a vulnerable population where the slightest perturbations to their location and wiring with excitatory neurons can contribute to the acquisition of neurological disorders like autism, schizophrenia and epilepsy.;During development, cortical interneurons migrate tangentially from the …

Inhibiting The Cannabinoid Catabolic Enzyme Magl To Potentiate The Anti-Arthritic Properties Of The Synthetic Glucocorticoid Dexamethasone, Sara R. Nass

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rheumatoid arthritis (RA, Table 1) is the most common type of inflammatory arthritis, and is characterized by swelling, inflammation, pain, and destruction of the synovial joints (i.e., knees, elbows, wrists, hips, and fingers). Glucocorticoid receptor agonists are a type of steroid hormone and are among the most common treatments for inflammatory arthritis because of their powerful anti-inflammatory effects. However, harmful side effects are associated with these glucocorticoids (GCs), including increasing patients' vulnerability to infections. Cannabinoids (i.e., cannabis-like signaling molecules) exert anti-inflammatory and analgesic effects with limited side effects compared to traditional immunosuppressants making them excellent targets for the development of …

Narrow Representation? The Impact Of Implicitly And Explicitly Racial Issues On Opinion And Representation, Franchesca V. Nestor Jan 2017

Narrow Representation? The Impact Of Implicitly And Explicitly Racial Issues On Opinion And Representation, Franchesca V. Nestor

Graduate Theses, Dissertations, and Problem Reports (ETD)

My dissertation combines knowledge from the opinion, racial and ethnic politics, and representation literatures to examine Black and Latino opinion and representation on racially salient issues. I theorize that representation of Blacks and Latinos is a "narrow" representation, much more in line with Black and Latino opinion on issues that are explicitly, rather than implicitly, racial. To test this theory, I build upon the literature by considering intersectional identity and multiple methods of representation. In Chapter 2, I examine two questions: when do income and racial group differences occur on racially salient issues, and if splits occur between respondents of …

The Influence Of Police Profanity On Public Perception Of Excessive Force, Christina Patton Jan 2017

The Influence Of Police Profanity On Public Perception Of Excessive Force, Christina Patton

Graduate Theses, Dissertations, and Problem Reports (ETD)

Previous research has examined elements of police performance impacting community policing and police-citizen relationships, but no study has considered the impact of police use of profanity during arrest on public rating of force. Police profanity may negatively bias police-citizen interactions, and this bias could shape later interactions with community members, decrease the quality of police-community relations, or even result in public outcry over excessive use of force (White, Cox, & Baseheart, 1994). Further, profanity increases recipient physiological arousal in some settings (LaPointe, 2006) and aggressive behavior, which may exacerbate risk to the officer during an arrest and lead to more …

"Here There Is No Plague": The Ideology And Phenomenology Of Aids In Gay Literature, Michael Alan Buso Jan 2017

"Here There Is No Plague": The Ideology And Phenomenology Of Aids In Gay Literature, Michael Alan Buso

Graduate Theses, Dissertations, and Problem Reports (ETD)

This project considers the social movements, historical memory, and politics of health to trace the way the literature of the AIDS epidemic both documents and discloses the lived experiences of a community struggling in the midst of an epidemic. It focuses on the literature of AIDS, analyzing the underlying ideologies of AIDS and articulating a phenomenology of AIDS that goes beyond the feminist or queer ones already considered in current scholarship. I argue that the literature of AIDS reflects various ideological fantasies about AIDS that, depending on political preconceptions and ontologies of identity, must, out of necessity, exclude certain ideas …

Reimagining The Ssmint Software Package, Kelly Cecil Jan 2017

Reimagining The Ssmint Software Package, Kelly Cecil

Graduate Theses, Dissertations, and Problem Reports (ETD)

We examine two proposed indexing algorithms taking advantage of the new SSMinT libraries. The two algorithms primarily differ in their selection of documents for learning. The batch indexing method selects some random number of documents for learning. The iterative indexing method uses a single randomly selected document to discover semantic signatures, which are then used to find additional related documents. The batch indexing method discovers one to three semantic signatures per document, resulting in poor clustering performance as evaluated by human cross-validation of clusters using the Adjusted Rand Index. The iterative indexing method discovers more semantic signatures per document, resulting …

The Analysis Of The Fatty Acid Content Of Fingerprint Residues Using Gas Chromatographymass Spectrometry, Ashley R. Cochran Jan 2017

The Analysis Of The Fatty Acid Content Of Fingerprint Residues Using Gas Chromatographymass Spectrometry, Ashley R. Cochran

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the recurring issues in the practice of forensic science is human subjectivity, especially within the field of fingerprint examination. Smudged fingerprints at crime scenes that contain little to no ridge detail often cause problems for examiners who, in turn, are unable to make identifications or exclusions in the absence of DNA markers. In recent years, researchers have explored the chemical composition of fingerprint residues to either provide an alternative means for including or excluding potential donors, or to provide investigative leads. Research into the chemical composition of fingerprints has shown that it may be possible to determine sex, …
