Identifying Mechanisms Of Host Plant Specialization In Aphis Craccivora And Its Bacterial Symbionts, Thorsten Hansen

Theses and Dissertations--Entomology

Many insects form close relationships with microbial symbionts. Insect symbionts can provide novel phenotypes to their hosts, including influencing dietary breadth. In the polyphagous cowpea aphid, Aphis craccivora, the facultative symbiont Arsenophonus improves aphid performance on one host plant (locust), but decreases performance on other plants. The goal of my thesis was to investigate the mechanism by which Arsenophonus facilitates use of locust. First, I assembled an Aphis craccivora-Arsenophonus-Buchnera reference transcriptome to conduct RNAseq analysis, comparing gene expression in aphids feeding on locust and fava, with and without Arsenophonus infection. Overall, few transcripts were differentially …

Exploring Factors Facilitating Sexual Self-Disclosure For Women, Caitlin Marie Grasson

Theses and Dissertations--Family Sciences

Sexual Self-Disclosure is an important part of a relationship, however, often times, women do not feel it is appropriate to engage in. Specifically, many women do not disclose their sexual preferences, or what acts they do or do not find satisfying, with their partner. This lack of sexual self-disclosure keeps women from being able to have their own sexual needs met. This phenomenological study aimed to understand the factors that facilitate sexual self-disclosure for women in relationships. The participants (n=8) were women between the age of 24-30 who were in a committed sexual relationship for more than three months, but …

Internal Medicine Faculty Publications

Background. Central nervous system (CNS) histoplasmosis is a life-threatening condition and represents a diagnostic and therapeutic challenge. Isolation of Histoplasma capsulatum from cerebrospinal fluid (CSF) or brain tissue is diagnostic; however, culture is insensitive and slow growth may result in significant treatment delay. We performed a retrospective multicenter study to evaluate the sensitivity and specificity of a new anti-Histoplasma antibody enzyme immunoassay (EIA) for the detection of IgG and IgM antibody in the CSF for diagnosis of CNS histoplasmosis, the primary objective of the study. The secondary objective was to determine the effect of improvements in the Histoplasma galactomannan …

Bi-Objective Optimization Of Kidney Exchanges, Siyao Xu

Theses and Dissertations--Computer Science

Matching people to their preferences is an algorithmic topic with real world applications. One such application is the kidney exchange. The best "cure" for patients whose kidneys are failing is to replace it with a healthy one. Unfortunately, biological factors (e.g., blood type) constrain the number of possible replacements. Kidney exchanges seek to alleviate some of this pressure by allowing donors to give their kidney to a patient besides the one they most care about and in turn the donor for that patient gives her kidney to the patient that this first donor most cares about. Roth et al.~first discussed …

Leveraging Overhead Imagery For Localization, Mapping, And Understanding, Scott Workman

Theses and Dissertations--Computer Science

Ground-level and overhead images provide complementary viewpoints of the world. This thesis proposes methods which leverage dense overhead imagery, in addition to sparsely distributed ground-level imagery, to advance traditional computer vision problems, such as ground-level image localization and fine-grained urban mapping. Our work focuses on three primary research areas: learning a joint feature representation between ground-level and overhead imagery to enable direct comparison for the task of image geolocalization, incorporating unlabeled overhead images by inferring labels from nearby ground-level images to improve image-driven mapping, and fusing ground-level imagery with overhead imagery to enhance understanding. The ultimate contribution of this thesis …

Surface And Structural Modification Of Carbon Electrodes For Electroanalysis And Electrochemical Conversion, Yan Zhang

Theses and Dissertations--Chemistry

Electrocatalysis is key to both sensitive electrochemical sensing and efficient electrochemical energy conversion. Despite high catalytic activity, traditional metal catalysts have poor stability, low selectivity, and high cost. Metal-free, carbon-based materials are emerging as alternatives to metal-based catalysts because of their attractive features including natural abundance, environmental friendliness, high electrical conductivity, and large surface area. Altering surface functionalities and heteroatom doping are effective ways to promote catalytic performance of carbon-based catalysts. The first chapter of this dissertation focuses on developing electrode modification methods for electrochemical sensing of biomolecules. After electrochemical pretreatment, glassy carbon demonstrates impressive figures-of-merit in detecting small, redox-active …

Mechanisms And Potential Therapy On Disrupted Blood Pressure Circadian Rhythm In Diabetes, Tianfei Hou

Theses and Dissertations--Pharmacology and Nutritional Sciences

Arterial blood pressure (BP) undergoes a 24-hour oscillation that peaks in the active day and reaches a nadir at night during sleep in humans. Reduced nocturnal BP fall (also known as non-dipper) is the most common disruption of BP circadian rhythm and is associated with increased risk of untoward cardiovascular events and target organ injury. Up to 75% of diabetic patients are non-dippers. However, the mechanisms underlying diabetes associated non-dipping BP are largely unknown. To address this important question, we generated a novel diabetic db/db-mPer2^Luc mouse model (db/db-mPer2^Luc) that allows quantitatively measuring of mPER2 protein oscillation …

The purpose of this study was to examine national survey data from across the United States for respondents from two-year community colleges. Historically little empirical evidence exists in the literature about this population of students who identity as sexual minorities. The study begins with a historical overview of the LGBTQ rights movement. This provides a baseline for why studies including this invisible minority group are important and especially timely for two-year college campuses. Literature is barrowed from four-year college and university studies. Data were analyzed using the Rasch Partial Credit model. This analysis included testing for data-fit to the model, …

An Examination Of Relations Among Fear, Guilt, Self-Compassion, And Multicultural Attitudes In White Adults, Whitney W. Black

Theses and Dissertations--Educational, School, and Counseling Psychology

Structural racism is often perpetuated by well-intentioned White individuals who passively accept or are unaware of its existence. However, when their perceptions and understanding of the world are challenged through learning about structural racism, White people may experience emotions such as fear, and guilt, which seem to serve either a debilitating or a motivating role in multicultural attitude development. Self-compassion, which is the ability to process distressing emotions without resorting to avoidance of the emotional experience, may help White individuals work through strong negative affect that accompanies an awareness of structural racism and ultimately aid in the development of multicultural …

The Cinematic College Professor: Conceptions And Representations, John C. Fitch Iii

Theses and Dissertations--Educational Policy Studies and Evaluation

Depictions of college professors in American films are common, and while a number of studies have investigated various aspects of college life in motion pictures, few have focused exclusively on the cinematic professoriate. In addition to being an indelible part of history, cinematic depictions of college professors are part of the national discourse on the role and function of the faculty and university. An investigation of how college professors have been represented in American films, and how these representations are read and created by real-life college professors and filmmakers may provide a deeper understanding of the relationship between popular culture …
