Modeling Place Vulnerability of HIV/AIDS in Texas

Description: This study provides a measurable model of the concept of place vulnerability for HIV/AIDS that incorporates both community and structural level effects using data provided at the ZIP code level from the Texas Department of State Health Services. Sociological literature on the effects of place on health has been growing but falls short of providing an operational definition of the effects of place on health. This dissertation looks to the literature in medical/health geography to supplement so… more

Modeling Transition Metal Chemistry for Catalytic Functionalization of Molecules

Description: The diversity of transition metal complexes allows for a wide range of chemical processes to be mediated by the metal, from catalysis to surface chemistry. Investigations into the structure and electronic configuration of transition metal complexes allow for tuning of desired species by modifications to the ligands and/or metals to achieve more efficient thermodynamics and kinetics for the process of interest. Transition metals, often used in catalysts for a number of important processes, requi… more

Molecular Basis of Plant Defense Against Aphids: Role of the Arabidopsis Thaliana PAD4 and MPL1 Genes

Description: Myzus persicae (Sülzer), commonly known as green peach aphid (GPA), utilizes its slender stylet to penetrate the plant tissues intercellularly and consume copious amounts of photoassimilates present in the phloem sap causing extensive damage to host plants. The compatible interaction between GPA and Arabidopsis thaliana enabled us to characterize plant response to aphid infestation. Upon GPA infestation, Arabidopsis PAD4 (PHYTOALEXIN DEFICIENT4) gene modulates premature leaf senescence, which i… more

Mycielski-Regular Measures

Description: Let μ be a Radon probability measure on M, the d-dimensional Real Euclidean space (where d is a positive integer), and f a measurable function. Let P be the space of sequences whose coordinates are elements in M. Then, for any point x in M, define a function ƒn on M and P that looks at the first n terms of an element of P and evaluates f at the first of those n terms that minimizes the distance to x in M. The measures for which such sequences converge in measure to f for almost every sequence a… more

Mythic Archaeologies: The Impact of Visual Culture on the Art and Identity of Four Hopi Artists

Description: This qualitative critical ethnography examines how visual culture impacted the identity and art of four Hopi artists. Sources of data included a personal journal, artists’ interviews, group discussion, art work interpretations, and historical research of Hopi art, visual culture, and issues of native identity. In particular, my analysis focused on issues of power / knowledge relationships, identity construction, and the artist as co-constructor of culture through personal narratives. Implicatio… more

NNS Use of Adverbs in Academic Writing

Description: Recent studies have begun to redefine the idea of accuracy in second language acquisition to include not only grammatical correctness, but also native-like selection. This is an exploratory study aimed at identifying areas of nonnative-like selection of adverbs, such as sentence position, semantic category preferences, frequency of use and breadth of word choice. Using corpus-linguistic methods it compares the writing of nonnative English speakers at an intermediate and advanced level to both… more

Novice Generalist and Content teachers’ Perceptions of Contextual Factors Affecting Personal Teaching Efficacy

Description: New teachers begin the school year with optimism and enthusiasm, but their excitement quickly wanes as they encounter the realities of the everyday life of a teacher. When they do not experience the successes they predicted, many begin to doubt their capabilities, which results in a lowered sense of teaching efficacy. This descriptive study was designed to identify the contextual factors novice teachers perceive as influences on personal teaching efficacy and to examine the relationships betwee… more

Photophysics and Photochemistry of Copper(I) Phosphine and Collidine Complexes: An Experimental/Theoretical Investigation

Description: Copper(I) complexes have been studied through both experimental and computational means in the presented work. Overall, the work focuses on photophysical and photochemical properties of copper(I) complexes. Photophysical and photochemical properties are found to be dependent on the geometries of the copper(I) complexes. One of the geometric properties that are important for both photochemical and photophysical properties is coordination number. Coordination numbers have been observed to be … more

Posttraumatic Growth: Behavioral, Cognitive, and Demographic Predictors

Description: Recent trauma research argues trauma results in distinct positive and negative consequences, however; many trauma variables positively correlate with both outcomes. This study examined posttraumatic growth (PTG) and post-traumatic stress disorder (PTSD) symptoms as positive and negative trauma outcomes. Behavioral, cognitive, and demographic correlates and predictors were assessed to help clarify differences between the two outcomes. While several behavioral factors were common to both PTG and … more

Prison Productions: Textiles and Other Military Supplies from State Penitentiaries in the Trans-Mississippi Theater during the American Civil War

Description: This thesis examines the state penitentiaries of Louisiana, Arkansas, and Texas that became sources of wartime supplies during the Civil War. A shortage of industry in the southwest forced the Confederacy to use all manufactories efficiently. Penitentiary workshops and textile mills supplied a variety of cloth, wood, and iron products, but have received minimal attention in studies of logistics. Penitentiary textile mills became the largest domestic supplier of cloth to Confederate quartermaste… more

Psychopathy and Antisocial Personality Disorder: Gender Differences in Empathy and Alexithymia

Description: Traditional conceptualizations of psychopathy highlight the importance of affective features of the syndrome in perpetuating social deviance. However, little research has directly investigated the callousness that psychopathic offenders display toward society and their victims. The current study investigated the roles of empathy and alexithymia in psychopathy among male and female incarcerated offenders, particularly in distinguishing psychopathy from antisocial personality disorder. Gender dif… more

PTSD Symptoms and Dominant Emotional Response to a Traumatic Event: An Examination of DSM-IV Criterion A2

Description: To qualify for a diagnosis of posttraumatic stress disorder the DSM-IV requires that individuals report dominant emotions of fear, helplessness, and horror during the trauma. Despite this stipulation, traumatic events can elicit a myriad of emotions other than fear such as anger, guilt or shame, sadness, and numbing. The present study examined which emotional reactions to a stressful event in a college student sample are associated with the highest levels of PTSD symptoms. Results suggest mixed… more

A Randomized Clinical trial of Cognitive-Behavioral Therapy for Insomnia in a College Student Population

Description: Nearly 10% of college students experience chronic insomnia. Cognitive-behavioral therapy for insomnia (CBTi) is an empirically validated multi-component treatment that has been demonstrated to produce reliable and durable benefits in the general adult population. However, there have been no studies examining the effectiveness of multi-component CBTi in a college student population, even though many studies have examined the efficacy of single treatment modalities. These young adults are differe… more

Re-Envisioning an Eighteenth-Century Artifact: A Postmodern Reading of Tristram Shandy

Description: The interjection of a new and dynamically different reading of Lawrence Sterne’s Tristram Shandy is imperative, if scholars want to clearly see many of the hidden facets of the novel that have gone unexamined because of out-dated scholarship. Ian Watt’s assumption that Sterne “would probably have been the supreme figure among eighteenth-century novelists” (291) if he had not tried to be so odd, and the conclusion that he draws, that “Tristram Shandy is not so much a novel as a parody of a novel… more
