Spatial Ecology, Genetic Diversity And Population Structure Of Armenian Vipers, Montivipera Raddei, In Two Different Landscapes, Jeffery Alan Ettling

Dissertations

In an effort to gain a better understanding of the impact that human-modified landscapes are having on snake populations I studied the spatial ecology, gene diversity and population structure of the Armenian Viper, Montivipera raddei in two different landscapes in Armenia. We first examined the spatial ecology and habitat use of Armenian Vipers in a human-modified landscape with a combination of agricultural fields and overgrazed native steppe habitat. While there were no differences in movement rates for either sex through croplands compared to steppe, we did find that males had larger home ranges during the spring if it included cropland. …

The Soldier And The Cigarette: 1918-1986, Joel Richard Bius

Dissertations

The military-industrial complex has been the topic of intense conversation among historians since President Dwight Eisenhower first gave the phrase life in January 1961. The term typically conjures up images of massive weapons procurement programs, but it also ironically involved one of the world’s most highly-engineered consumer products, the manufactured cigarette. “The Soldier and the Cigarette: 1918–1986” describes the unique, often comfortable, yet sometimes controversial relationships among the military, the cigarette industry, and tobaccoland politicians. The dissertation argues that the federal government’s first cigarette warning in 1964 changed a relationship between soldiers and cigarettes that the Army had fostered for …

Perceptions Of Incivility In Nursing Education: A Survey Of Associate And Baccalaureate Program Nursing Students, Kim Elaine Young Vickous

Dissertations

This study explored differences of nursing students’ perceptions of student and faculty incivility, measured using the Incivility in Nursing Education survey, across semesters and between Associate and Baccalaureate of Science nursing students. A sample of 262 Associate and Baccalaureate of Science nursing program students enrolled in second, third, and fourth semesters from a state university located in the mid-south participated in the study. Descriptive statistics, Analysis of Variance, and Independent t-tests were conducted to examine the research questions. These questions explored what student and faculty behaviors were perceived as uncivil and most frequently occurring (disruptive and threatening) uncivil behavior in …

Shakespeare And Boyhood: Early Modern Representations And Contemporary Appropriations, Marvin Tyler Sasser

Dissertations

This dissertation demonstrates that Shakespearean boyhood, both in early modern plays and contemporary reimaginings for young readers, critiques patriarchal and hegemonic ideals through the rhetoric and behavior of boy characters. Although critics have called Shakespeare’s boy characters indistinguishable, I find that they provide Shakespeare a unique resource to offer persuasive skepticism about heroic conventions, education, and political instability. This project begins by examining the lexical network of boy in order to chart its uses in early modern England. The subsequent three chapters establish how Shakespeare uses boys to comment on a range of ideal manhoods, such as the chivalrous …

The Knowledge Weapon: Ways Of Knowing, Annette Christine Boehm

Dissertations

This collection of poems explores the language of knowledge and instruction. While it can provide a sense of security, what we are given as ‘knowledge’ is frequently unreliable or even misleading, and used much like a weapon.

An Evaluation Of The Attitudes, Beliefs, And Mental Health Literacy Of Young African American College Graduates, Marshae Antoinette Mcneal

Dissertations

The aim of this study was to examine the relationships between the attitudes, beliefs, and mental health literacy of young college-educated African Americans as compared to their Caucasian counterparts. Previous research indicates these two populations differ when receiving services for mental illness. The goal of this study was to see if this difference is due to their mental health literacy level, attitudes toward seeking help, as well as their attitudes and beliefs toward mental illness. A quantitative analysis was conducted using elements of the MacArthur Mental Health Module and the Attitudes toward Seeking Professional Psychological Help Scale-Short Form (ATSPPHS-SF) to …

Capturing Critical Whiteness: Portraits Of White Antiracist Professors, Melanie Jane Stivers

Through the thick description of setting and context, white privilege is named as the researcher's experience and that of each of the participants. The researcher examines ways in which each participant strives to disrupt racism. Using a lens of critical theory applied through critical pedagogy and critical whiteness philosophies, the researcher highlights the following themes as they emerge: education, exposure, empathy, and engagement. This study contributes to the literature by providing examples of white professors challenging racism …

Race, Socialization, And Civility: Interrogating The Communicative Construction Of The White Habitus, Charles Kyle Rudick

Dissertations

The purpose of this dissertation project was to understand how institutions of higher education, through both punishments and rewards, ensure that dominant cultural codes are "taught" to students of color in ways that normalize whiteness ideologies. I wanted to understand racism in higher education through the lens of socialization to show the ways in which institutional members (un)intentionally conflate dominant cultural codes with the "correct" or "normal" way to think, act, or speak. Furthermore, I was interested in the ways that students of color take up, defer, resist, adapt, mix, subvert, and/or accommodate the institutional practices that (re)produce racial power …

Preferences For Evidence-Based Depression Treatments: An Emphasis On Patient-Focused Care, Lauren A. Frye

Dissertations

Research indicates most depressed patients in the general U.S. adult population seek depression treatment in primary care settings where the prevailing method of treatment is antidepressant medication. Although primary care physicians regard this approach as a preferable first line method of depression treatment, studies indicate many patients do not. Several studies have found depressed patients in these settings prefer psychotherapy or counseling over anti-depressant medication. Many advocate patient preferences should be integral to the treatment decision making process. There is a demonstrated propensity towards psychotherapy or counseling over antidepressant medication among depression patients. However, it is unclear which psychological depression …

An Evaluation Of The Primary Care Providers’ Perspective Of The Effects Of Moderate Alcohol Consumption On Health, Gisele Tchamba

Dissertations

The complexity of health benefits of moderate alcohol consumption (MAC) is well documented. From the World Health Organization recent report, impact of harm from alcohol consumption was 3.3 million deaths or 5.9 percent of all global deaths (WHO, 2014).

Yet, the benefits of MAC for better health and longer life expectancy compared with abstinence are advocated in numerous studies (Nova, Baccan, Zapatera and Marcos, 2012). However, the nature of alcohol, its role on human sufferings has generated disagreements in the scientific community. Analysis of the results of early studies advocating better health for moderate drinkers, reveal discrepancies regarding the influence …

Musical Portrayals Of Death In Mussorgsky’S Songs And Dances Of Death, Graham Michael Anduri

Dissertations

Musorgsky’s Songs and Dances of Death presents a set of unique portrayals of death in art song literature. Aside from the obvious challenge of the Russian language and Cyrillic alphabet which are unfamiliar to most Western performers, the unique musical style, historical context, and complex psychological implications of Songs and Dances of Death require a good deal of study before one can fully grasp the profundity and importance of this cycle.

Musorgsky’s views on music and life, the Zeitgeist in which these songs were composed, a historical analysis of the medieval Dance of Death tradition and its influence on the …

Innovative Governance And Natural Resource Management In Kenya: Procedural And Substantive Outcomes Of Civil Society Participation, Jane Omudho Okwako

Dissertations

Kenya’s environmental sector is embracing co-management to address major threats to wildlife. In the past two decades, the Municipal-Community-Private Sector Partnership (MCPP) model evolved to address the threats. This dissertation seeks to explain variations in partnership outcomes. It evaluates whether the model as introduced empowers communities to be conservation stewards.

This study hypothesized the impact of five variables. These are decentralization of power, elite support, capacity of community organizations, partnership formalization, and resources expended. The findings confirm that three variables are indispensable and two minimally influence empowerment. More decentralized management structures are enabling and supportive of empowerment. However, empowerment is …

Perceived Attributes And Factors Influencing Instructors’ Using E-Textbooks In Higher Education, Sirui Wang

Dissertations

As digital content, e-Textbooks display text on the screen, integrate multimedia within textual components, and allow reading on portable devices; which make learning highly interactive, flexible, and immediately accessible, increase students’ engagements in learning, and make learning content portable, transferrable, and searchable. Those advanced features did not bring prosperity in using e-Textbooks in education. The adoption of using e-Textbooks in higher education is still far from its confirmation stage. The purpose of this study was to examine the relationship between the perceived attributes of using e-Textbooks by instructors and their actual use of e-Textbooks in higher educational settings, to discuss …

Moving College Students To A Better Understanding Of Substrate Specificity Of Enzymes Through Utilizing Multimedia Pre-Training And An Interactive Enzyme Model, Mounir R. Saleh

Dissertations

Scientists’ progress in understanding enzyme specificity uncovered a complex natural phenomenon. However, not all of the currently available biology textbooks seem to be up to date on this progress. Students’ understanding of how enzymes work is a core requirement in biochemistry and biology tertiary education. Nevertheless, current pre-college science education does not provide students with enough biochemical background to enable them to understand complex material such as this. To bridge this gap, a multimedia pre-training presentation was prepared to fuel the learner’s prior knowledge with discrete facts necessary to understand the presented concept. This treatment is also known to manage …

Secure And Reliable Routing Protocol For Transmission Data In Wireless Sensor Mesh Networks, Nooh Adel Bany Muhammad

Dissertations

Abstract

Sensor nodes collect data from the physical world then exchange it until it reaches the intended destination. This information can be sensitive, such as battlefield surveillance. Therefore, providing secure and continuous data transmissions among sensor nodes in wireless network environments is crucial. Wireless sensor networks (WSN) have limited resources, limited computation capabilities, and the exchange of data through the air and deployment in accessible areas makes the energy, security, and routing major concerns in WSN. In this research we are looking at security issues for the above reasons. WSN is susceptible to malicious activities such as hacking and physical …

A Phenomenological Study Of Health Professionals’ Perceptions Of Good And Bad Pediatric Hospital Deaths, Self-Care Needs And Lingering Distress, Carmen Nichole Spalding

Dissertations

The death of a child is devastating. Although death is a part of every life, a child dying seems out of order in current times and in the context of Western Healthcare. Health professionals (HP) caring for dying children frequently report suffering. In the past four decades, HP have been concerned with providing a “good death” for patients at the end-of-life (EOL). While studies have shown what a good death includes in elderly patients in various settings, few studies have examined what constitutes a good death for pediatric patients within the hospital setting. No studies were found examining healthcare workers …

Proteomic Analyses Of Snake Venoms With An Examination Of The Biological Roles And Anti-Cancer Effects Of Venom Disintegrins, Anthony J. Saviola

Dissertations

For decades, snakes and snake venoms have been utilized in numerous

aspects of biological and biomedical research. Behaviorally, snakes have been

examined for their extraordinary chemosensory capabilities, providing a detailed

understanding of their foraging ecology and predatory responses. The presence of

a highly complex vomeronasal organ has enabled snakes to not only respond to,

but also discriminate between a high-range of heterospecific, conspecific,

predatory, and prey-derived chemical odors.

Snake venom has allowed for a transition in predatory behaviors, and this

often complex mixture of proteins and peptides has provided researchers with an

ever growing catalog of natural compounds that may …

Predicting Multi-Trophic Consequences Of An Emerging Disease, Adam D. Chupp

Dissertations

There are numerous examples of how exotic insect pests and pathogens have altered the dominance of native tree species and the ecological processes and function related to those species. While targeted species may persist in a functionally altered state via vegetative sprouting, the widespread decimation of a species can have dramatic direct and indirect consequences for organisms in multiple trophic levels. Devastation due to alien insect herbivores poses the greatest threat to native insect larvae that specialize on the impacted host species. The loss of pollinators whose larvae feed on impacted species and provide services for native plants may also …

On Moral Imagination And Indigenous Wisdom: How Leaders Approach Moral-Ethical Tension In Post-Modern Bali, Alan James Yu

Dissertations

Moral imagination can be defined as an act or process that involves the consideration of a moral-ethical tension and the generation of a novel and appropriate course of action that accommodates the situation. The purpose of this study was to understand how, if at all, might Balinese leaders demonstrate moral imagination using their sociocultural values. The following supporting research questions frame this study: (a) What sociocultural values inform the process by which Balinese leaders approach moral-ethical tension? (b) What specific interventions are part of Balinese leaders’ process in achieving their stated vision? (c) How, if at all, might the …

Psychoneuroimmunology And Chronic Pain, Sarah E. Giron

Dissertations

There is increasing evidence linking chronic pain to altered levels of central nervous system (CNS) inflammation and increased levels of perceived pain, anxiety, depression and sleep disturbance. However the inflammatory molecules responsible for physiologic and psychological components of chronic pain still warrant identification and exploration. Using central inflammation as a paramount factor in the creation and maintenance of chronic pain, this study aimed to investigate and describe the physical and psychological aspects of chronic pain associated with CNS inflammation.

Using a cross-sectional correlational design, cerebrospinal fluid (CSF) inflammatory cytokine patterns present in 8 chronic pain participants were compared to inflammatory …

Multi-Level Adjustments In Singing Behavior By A Migratory Songbird In Response To Urbanization, Jacob Job

Dissertations

The spread of high-amplitude anthropogenic noise across natural landscapes is a serious issue for vocally communicating animals. Noise disrupts communication, which has implications for individual fitness and population persistence. In response, animals adjust their vocal signals with increasing noise. As the increase in noise has occurred on a relatively short time scale, evolutionary responses are likely not the primary cause of adjustments. Instead, short-term behavioral adjustments may drive population differences; however, such adjustments are currently not well understood. Moreover, noise is only one characteristic of urbanized landscapes and whether other characteristics, such as highly reverberant surfaces interact with noise to …

Comparative Phylogeography And Demographic Histories Of West Indian Birds, Maria Wilhelmina Barbosa De Oliveira Pil

Dissertations

My dissertation investigates the demographic history of multiple island populations of several Caribbean bird species through an assessment of contemporary genetic diversity, while inferring relationships between the comparative demography of individual island populations and characteristics of the islands and species. The sizes and distributions of populations vary over time, and episodes of expansion and contraction create characteristic patterns of genetic variation within and among populations. Consequently, contemporary patterns of genetic diversity open a window onto demographic and phylogeographic history. The strength of the study lies in the scale and comprehensiveness of the analysis, encompassing most of the West Indian islands …

Transient Cardiovascular Hemodynamics In A Patient-Specific Arterial System, Jr Rodward Hewlin

Dissertations

The ultimate goal of the present study is to aid in the development of tools to assist in the treatment of cardiovascular disease. Gaining an understanding of hemodynamic parameters for medical implants allow clinicians to have some patient-specific proposals for intervention planning. In the present study a full cardiovascular experimental phantom and digital phantom (CFD model) was fabricated to study: (1) the effects of local hemodynamics on global hemodynamics, (2) the effects of transition from bed-rest to upright position, and (3) transport of dye (drug delivery) in the arterial system. Computational three dimensional (3-D) models (designs A, B, and C) …

Mechanisms Underlying Control Of Anti-Microbial Immunity By Acetylcholinesterase Inhibition, Ray M. Esam Al-Barazie

Dissertations

Inflammation is a crucial defense mechanism that protects the body from the devastating effects of invading pathogens. However, an unrestrained inflammatory reaction may result in systemic manifestations with dire consequences to the host. The extent of activation of the inflammatory response is tightly regulated through immunological and neural pathways. Previously, we demonstrated that cholinergic stimulation confers enhanced protection in experimental animals orally infected with a lethal dose of Salmonella typhymurium. In this study, we investigated the mechanism by which this enhanced protection takes place. We showed that cholinergic stimulation enhanced host survival following oral-route infection, which correlated with significantly reduced …
