The Combined Neuropharmacology And Toxicology Of Major 'Bath Salts' Constituents Mdpv, Mephedrone, And Methylone, Serena Allen

Electronic Theses and Dissertations

The synthetic cathinones, 3,4- methylenedioxypyrovalerone (MDPV), 4-methylmethcathinone (mephedrone), and 3,4- methylenedioxymethcathinone (methylone), gained worldwide notoriety as the psychoactive components of ‘bath salts;’ a marketing term used to circumvent federal drug laws and permit their legal sale. Previous studies have shown that these drugs share pharmacological characteristics with cocaine and the amphetamines, however, descriptions of their neurotoxic properties are limited. Moreover, while forensic analysis has revealed that the most frequently abused bath salts ‘brands’ contain binary and ternary mixtures of MDPV, mephedrone, and methylone, the majority of preclinical research has focused on explicating the individual effects of these drugs. Therefore, the …

Factors Influencing Millennials’ Perception Of And Attitudes Toward Therapy, Kaylee Jackson

Electronic Theses and Dissertations

The millennial generation (those born after 1985) appears to be seeking mental health services (MHS) less frequently than older generations. Additionally, this generation is reportedly more narcissistic and entitled than older generations and have maladaptive helicopter parents. One explanation for millennials’ underutilization of MHS would be to attribute this to their narcissism, entitlement, and helicopter parents. The purpose of this study was to investigate whether differences exist between millennials and non-millennials regarding their levels of narcissism, entitlement, experiences of helicopter parenting, and attitudes towards therapy. Additionally, the study predicted that increased levels of narcissism, entitlement, and helicopter parenting would be …

You Are What You Wear: Clothing And American Authors Of The Early 20th Century, Alyssa Quinn Johnson

Electronic Theses and Dissertations

Though clothes are often said to “make the man,” they are not frequently said to build a character. This thesis explores the ways in which clothing was a performative tool for those who wore it during the 1920s in America as well as for authors who wrote about this world in which they lived. This study’s theoretical framework is inspired by Judith Butler’s concept of the performative; it is also influenced by historical research into the clothing of the 1920s. Primary texts explored include F. Scott Fitzgerald’s The Great Gatsby and Tender Is the Night, Nella Larsen’s Quicksand, and …

Tidal Creek And Substrate Effects On Oyster Reef Associated Fish And Decapod Condition And Density, Thomas S. Funk

Electronic Theses and Dissertations

Oyster reefs are essential fish habitat and a worldwide loss of reefs has the potential to negatively affect reef-associated nekton populations. Along the 100 km Myrtle Beach, SC shoreline, oyster reefs ostensibly have disappeared within swash tidal creeks, which are anthropogenically altered estuarine systems that drain into the coastal ocean directly over shoreline beaches. To address oyster reef losses, a series of shell bag reefs were constructed within multiple swash tidal creeks. Reefs also were constructed in tidal creeks associated with estuaries directly connected to the ocean by an inlet. The purpose of this study was to compare nekton usage …

The Empathy Mitigation: Empathy And Its Impact On Pain Perception And Altruistic Motivation, Amanda Daly

Electronic Theses and Dissertations

Empathy and its impact on pain perception has been studied narrowly with the focus being on participants receiving empathy during a pain procedure. This study reversed the focus and ran a standard cold pressor test (CPT) in the context of an empathy frame structured to elicit an empathic response for others from participants. It was hypothesized that the group receiving the empathic frame would have longer CPT times due to alterations in pain perception from empathy activation and these subjects’ self-reported state-trait empathy level would positively correlate with the increased times. 85 subjects participated with a control group of 43 …

Interplay Of Molecular And Nanoscale Behaviors In Biological Soft Matter, Nicholas Ciaffone

Electronic Theses and Dissertations

The complexity of biological soft matter at the sub-micrometer level is fundamentally correlated to the functionalities at the larger scale. Reflecting the level of heterogeneities in the properties of systems remains challenging when probing small scales, due to the mismatch between the area surveyed with the tools offering nanoscale resolution, such as atomic force microscopy (AFM), and the scale of natural variations inherent to biology. Hence, to understand the physiological and mechanical alterations that occur within a single cell relative to a cell population, a multiscale approach is necessary. In this work we show that it is possible to observe …

Development Of Low Frequency Electron Paramagnetic Resonance Methods And Instrumentation For Biological Applications, Laura A. Buchanan

Electronic Theses and Dissertations

EPR is a powerful biophysical tool that can be used to measure tumor physiology. With the addition of magnetic field gradients, the spectral properties of paramagnetic species can be mapped. To facilitate EPR imaging, methods and instrumentation at frequencies between 250 MHz and 1 GHz were developed.

At low spin concentrations, the rapid scan background signal is often many times larger than the EPR signal of interest. To help remove the background contribution, a data acquisition procedure that takes advantage of a cross-loop resonator and bipolar power supplies was developed at 250 MHz. In this procedure, two scans are collected. …

Crafting Local Food Narratives With Immigrant Voices: Participatory Ethnography Among Somali Bantu Farmers In West Denver, Raymond Alexander Pang

Electronic Theses and Dissertations

In 2013, a non-profit, Re:Vision, established the Ubuntu Farm to work with the local Somali Bantu refugee population. It was supposed to improve access to fresh produce, offer educational opportunities, skill training and more. Early on in 2014, it became clear Re:Vision was not delivering on its promises, and by 2015 the farm had ceased to exist. Using participant observation, interviews with farm participants and staff and a review of publicly accessible financial documents, I argue that Re:Vision maintained a conflict of mission, which contributed to their farms' failings, despite their ability to grow plenty of vegetables. From there, I …

Restive Subjects: Russian Protest, 2007–2013, Carey C. Neill

Electronic Theses and Dissertations

This dissertation develops and evaluates a structural theory of protest onset, applied to the Russian case. Russian stability has become a pressing international political concern, as Putin has annexed the Crimea, fomented one war, in Ukraine, and become a major player in another, in Syria. In December 2011, thousands of Russians gathered in Moscow, Saint Petersburg, and other cities for the largest set of protests since the fall of the USSR. Waves of protest have reappeared sporadically since. Each time, events create islands of dissent, spread widely, but unevenly, throughout the country - in a picture reminiscent of the pre-collapse …

An Exploratory Study Of Session Limited Models Of Therapy Outcomes In An Employee Assistance Program, Ivy C. Donaldson

Electronic Theses and Dissertations

Employee Assistance Programs (EAPs) have grown increasingly popular over recent years. The prevalence of organizations utilizing and investing in EAP services for their employees has grown; however, companies that purchase EAPs are not well-informed as to which session-models are most effective for various diagnoses. The current study is the first to explore treatment outcomes of session-limited models (measured by Therapist Perception of Change, TPC) for diagnoses (anxiety and depression) in an EAP delivery system. Outcomes were measured by TPC ratings including: a) Regressed, b) remained at Baseline, c) Improved, and d) issue was Resolved. Analyses (Chi-Square and =t-test) were used …

Discourses Of Deception: (Re)Examining America's War On Drugs, Benjamin Steven Boyce

Electronic Theses and Dissertations

America's war on drugs is a failed experiment that has caused more damage than it will ever prevent. From its original design to its contemporary manifestations, the war on drugs is a conflict that remains firmly rooted in white supremacy. In contemporary Western societies, the rhetoric of both political leaders and mass-mediated narratives becomes the raw material of subjective reality. Since the war on drugs began nearly a century ago, the spectacle of mass media has been consistently utilized by white political elites as a vehicle of misinformation - as a well-oiled machine for spreading the false social narrative that …

Binocular Rivalry Of Emotional Expressions, Daniel Stephen Lumian

Electronic Theses and Dissertations

A central debate in defining emotional space is whether emotions are organized categorically (e.g., fear, happy, disgust) or continuously (i.e., along the independent dimensions of valence and arousal). Emotional facial expressions are one tool often leveraged in trying to define emotional space. Faces are rich sources of social and emotional information. Faces, like emotions, can be organized in either categorical (e.g., happy, sad) or continuous (e.g., open-closed) ways. Therefore, understanding the relatedness of emotional facial expressions to each other may shed light on the underlying structure of emotions. Binocular rivalry (BR) is a tool which can be leveraged to measure …

Higher Education Student Debt & Tuition Costs, K. Harrison Maloy Jr

Electronic Theses and Dissertations

U.S. higher education tuition costs have risen at nearly double the rate of inflation over the past forty years. In 2012, student loan delinquency rose to 12% and surpassed credit card delinquency rates as the top category of consumer debt delinquency. Meanwhile, recently enacted federal policies advocate for increased higher education accessibility, affordability and attainability, but simultaneously promote educational institutions to increase spending with funds fueled by student debt. The growth of $136.8 billion in student loan delinquency has triggered decreasing participation in non-student debt markets by people with student loan debt. Fortunately, Americans continue to enroll in colleges at …

Fashion and lifestyle blogs serves as a new cultural space, where bloggers are viewed as influencers and set cultural, societal standards of an ideal womanhood. Female bloggers' various forms of labor - specifically, communicative, relational, and affective - establish a blogger's role in social and economic life and reiterate the significance of consumerism as a hallmark of femininity. Fashion and lifestyle bloggers are typically women, whose labor sustains the fashion and lifestyle blogging ecosystem. This occurs through consistent, branded communication; cultivating connections and relationships with followers and fellow bloggers; and transference of affect across digital divides, in real time, through …

Leadership Practices In Similar Schools With Varying Primary Grade Reading Outcomes: A Comparative Multiple-Case Study, Jacqueline M. Cuthill

Electronic Theses and Dissertations

Students who are below grade level before they leave third grade are less likely to graduate. A large number of schools are failing to increase student achievement in reading, especially for students of color and those who are economically disadvantaged. Leadership can influence student achievement; however, literature lacks specifics about leadership practices that could help school leaders improve student outcomes. This multiple-case study explores the leadership practices in three similar elementary schools with varying primary grade reading outcomes and contributes details about the leadership functions of Setting Direction, Developing People and Redesigning the Organization (Leithwood, Seashore, Anderson, & Wahlstrom, 2004). …

A Multi-State Comparison Of Nasp Domains Of Practice And School Psychologist Evaluation Rubrics, Courtney E. Hutchinson

Electronic Theses and Dissertations

This research study compares rubrics used to evaluate school psychologists to the National Association of School Psychologists (NASP) 10 Domains of Practice. Using a content analysis of state evaluation rubrics, the researcher determined the extent to which various state evaluation rubrics align with the NASP domains and selected terminology from the NASP domains. Results indicate a need for a comprehensive and NASP-endorsed rubric, to be used by certified and experienced school psychologists for evaluation purposes. This research study will inform efforts at school psychology training programs, local and state education agencies, the United States Department of Education, and the NASP.

Tau Aggregation, Conformational Selection, And Inhibition, Michael R. Holden

Electronic Theses and Dissertations

Tau fibrils are a pathological hallmark of over 20 neurodegenerative disorders, including Alzheimer's disease. There currently is no cure for these diseases and treatments are limited. Once Tau fibrils form in the brain, they propagate down neuronal networks, and this spreading is linked to disease progression. Studying the behavior and structure of Tau monomer and Tau aggregates therefore may give insight into methods by which the spread of Tau fibrils can be inhibited. The structures of the Tau fibrils from different diseases are thought to vary, partially giving rise to the different disease phenotypes. Tau natively binds to microtubules by …

Tides Of Cooperation: The Ebb And Flow Of Regional Cooperation In Latin America, Amaleia E. Kolovos

Electronic Theses and Dissertations

Regional organizations have developed into important global actors as they negotiate inter-regional trade agreements, regulate economic policies, and develop international security communities. States have much to gain from such regional cooperation efforts particularly in emerging regions such as Latin America. Such gains can include increased trade and economic relations, enhanced security, attracting external investment, and increasing bargaining power at the international level. With such gains to be had, one might expect states in these regions to regularly cooperate in order to achieve their common interests. However, this is clearly not always the case. Latin America has struggled for decades with …

The Whiteness Project Of Gentrification: The Battle Over Los Angeles' Eastside, Jaime Guzmán

Electronic Theses and Dissertations

For many years, the city of Los Angeles has declared war on communities of color. In the past decade, former communities of color like Echo Park, Silver Lake, and Highland Park have all been converted into predominantly white, affluent neighborhoods. In essence, working-class people of colors' neighborhoods are being uplifted in order to welcome a much more affluent population to town. The newest target of Los Angeles' gentrification for the past couple of years has been the greater Eastside. In this project I present my critical intervention of gentrification as a whiteness project. This critical intervention argues that gentrification …
