Exploring Male Counselors’ Experiences With Vulnerability In The Counseling Relationship, Hannah Edith Davis Kreider

Dissertations

While existing literature clearly indicates that the relationship between counselor and client is important and crucial for therapeutic progress (e.g., Norcross & Wampold, 2011), little research has been done on the experiences of counselors within the therapeutic relationship. Vulnerability has been noted as an important component of growth-fostering relationships (e.g., Jordan, 2008), however research is lacking on how counselors experience vulnerability with their clients. Within the field of counseling, men are underrepresented (Michel, Hall, Hays, & Runyan, 2013) and little research exists exploring their unique experiences as counselors. Additionally, due to gender role socialization, men are likely to struggle with …

School Policy And Practice To Tackle A Public Health Problem: Sudden Cardiac Arrest, Leigh Lynn Mcgown-Kauffman

Dissertations

Sudden cardiac arrest (SCA) is a leading cause of death in the United States. While the medical research has exhaustively documented that immediate response directly impacts survival rates in SCA and that schools could be the best catalyst for creating change by bystanders, there is little to no educational research addressing school policy or practices in regards to cardiac emergencies in schools. The purpose of this dissertation was to identify and describe characteristics of the Colorado schools that offer cardiopulmonary resuscitation (CPR) training and onsite automated external defibrillators (AED). Two research questions were answered, Of respondents, what are the characteristics …

A second set of interviews were conducted to collect information about the participants’ strategies for engaging Indonesian immigrants in physical activity. Seven purposefully selected participants were the respondents in these interviews. Data were analyzed using a three …

All Families Are Unique: Experiences Of Lesbian-Parented Families, Rachel Tova Gall

Dissertations

This study explored the experiences of families with lesbian mothers and elementary school-aged children residing in metropolitan areas of the United States. This phenomenology aimed to transcend comparative and binary research to include the voices of sexual minorities and children. Eight whole-family interviews were conducted in alignment with the study’s systemic-constructivist approach. A number of themes emerged from the data that were generally consistent with prior research. Mothers were intentional about the communities in which they surrounded themselves, the process of having children, and having discussions with children about potential discrimination. Participants saw themselves as advocates and were typically out …

Trying Times: Disability, Activism, And Education In Samoa, 1970-1980, Juliann Anesi

Dissertations - ALL

In the 1970s and 1980s, Samoan women organizers established Aoga Fiamalamalama and Loto Taumafai, which were educational institutions in Samoa, an island in the Pacific. Establishing these schools for students with intellectual and physical disabilities, excluded from attending formal schools based on the misconception that they were "uneducable". In this project, I seek to understand how parent advocates, allies, teachers, women organizers, women with disabilities, and former students of these schools understood disability, illness, inclusive education, and community organizing. Through interviews and analysis of archival documents, stories, cultural myths, legends related to people with disabilities, pamphlets, and newspaper media, I …

The Legends Of Bigfoot: Or How I Regained My Manhood, Blaine Mccarty

Master of Arts in American Studies Capstones

Masculinity is a culturally defined identity that exists with no single way to express it. However, the cultural politics police masculinity to appear natural and non-changing, but masculinity changes over history influenced by events and the culture from which it gets its definition. Because of this twofold influence on the identity, there is a constant struggle of the appropriate ways to express masculinity in its attempt to normalize itself by defining what is and is not masculine. This work examines how Bigfoot, the hairy fabled monster, embodies conversations about masculinity during a shift in the masculine identity in a constantly …

Preventing Thymus Involution In K5.Cyclin D1 Transgenic Mice Sustains The Naïve T Cell Compartment With Age, Michelle L. Bolner

Dissertations and Theses (Open Access)

The thymus maintains T cell receptor (TCR) repertoire diversity through perpetual release of self-MHC restricted naive T cells. However, thymus involution during the aging process reduces naïve T cell output, leading to defective immune responsiveness to newly encountered antigens. We have found that early thymus involution precipitates the age-associated shift favoring memory T cell dominancy in young control mice. Furthermore, we have shown that age-related thymus involution is prevented in mice expressing a keratin 5 promoter-driven Cyclin D1 (K5.D1) transgene in thymic epithelial cells (TECs). Thymopoiesis occurs normally in K5.D1 transgenic thymi and sustains T cell output to prevent the …

Investigation Of Quatitative Image Features From Pretreatment Ct And Fdg-Pet Scans In Stage Iii Nsclc Patients Undergoing Defintive Radiation Therapy, David Fried

Dissertations and Theses (Open Access)

The purpose of this work was to determine if quantitative image features (QIFs) extracted from computed tomography (CT) and flourodeoxyglucose (FDG) positron emission tomography (PET) could provide prognostic information to improve outcome models. Our goal for this work was to determine if it may one day be feasible to incorporate QIFs into personalized cancer care. QIFs were used to quantitatively characterize patient disease as seen on imaging. A leave-one-out cross-validation procedure was used to assess the prognostic ability of QIFs extracted from CT and PET in addition to conventional prognostic factors (CPFs). QIFs were found to improve model fit for …

As these topics are well-documented in many sources, this Paper serves as …

Lethal And Legal? The Ethics Of Drone Strikes, Shima D. Keene Dr.

Books, Monographs & Collaborative Studies

While supporters claim that drone warfare is not only legal but ethical and wise, others have suggested that drones are prohibited weapons under International Humanitarian Law (IHL) because they cause, or have the effect of causing, indiscriminate killings of civilians, such as those in the vicinity of a targeted person. The main legal justification made by the Barack Obama Administration for the use of armed drones is self-defense. However, there is ambiguity as to whether this argument can justify a number of recent attacks by the United States. In order to determine the legality of armed drone strikes, other factors …

Validating Side Scan Sonar As A Fish Survey Tool, Michael A. Bollinger

Theses and Dissertations

Hydroacoustic methods can be used to answer a variety of questions regarding fish populations and behavior. In this study, side scan sonar methodology was developed to quantify abundance and biomass and compared to established visual observation methods on SCUBA over artificial reef structures in the western Gulf of Mexico. Side scan sonar methods were equivalent to SCUBA surveys for measuring fish abundance over the same reef areas, however, abundances were significantly higher when the larger area sampled by side scan was utilized. Side scan sonar methods were also more time efficient than SCUBA, ROV and long line fishing methods (66.7%, …

Molecular Modeling And Mutational Mapping Of The Gpr119 Binding Site, Shane M. Askar

Theses and Dissertations

GPR119 receptor’s biological role in regulating glucose homeostasis has been studied extensively. Results in the scientific literature indicate that, when activated, GPR119 releases insulin in a glucose dependent manner. Currently the 3D structure of GPR119 has not been resolved.

The goal of this research is to use a combination of homology modeling and ligand docking studies to predict the binding mode of GPR119 ligands. Amino acids implicated to have direct interactions with docked ligands will further be assessed experimentally for their roll in binding and activation of GPR119. Our results indicate that residues W2656.48 and R813.28 are likely to be …

Decomposition And Nitrogen Dynamics Of Turtle Grass (Thalassia Testudinum) In A Subtropical Estuarine System, Monica Delgado

Theses and Dissertations

Seagrass beds are pivotal in the functioning of coastal ecosystems in terms of productivity, organic matter turnover and nutrient cycling. Aiming to document decay and nitrogen (N) dynamics of turtle grass (Thalassia testudinum) in a subtropical estuarine system, decomposition patterns of leaves and rhizomes were characterized and compared. Nitrogen usage during decomposition of tissues, and of live tissues and epiphytes growing on live leaves, was also quantified and compared. Stable isotope ratios allowed tracing N within the seagrass bed, following N incorporation into seagrass tissues from the surrounding media (water, sediment). Leaves had a higher N content and decomposed at …

Activation Of Microglia In The Rotenone Lymnaea Stagnalis Model Of Parkinson's Disease, Xiomara Galvan

Theses and Dissertations

Parkinson’s disease (PD) is the most common irreversible neurodegenerative movement disorder affecting approximately ten million people worldwide. In the central nervous system (CNS), PD is known by the selective loss of Dopamine (DA) cells of the substantia nigra pars compacta. Although the disease has been very widely studied, the underlying mechanisms are not yet understood. Several hypotheses have arisen as result of injury of the mitochondria, some experiments include microglia activation, microtubule damage, and reactive oxidative species, which all result in the death of DA cells. The theory of microglia activation upon inflammation was explored in this study. Using the …

A Handcrafted Multi-Branch Nerve Scaffold For In Vivo Peripheral Nerve Regeneration, Ridwan Fayaz Hossain

Theses and Dissertations

Arm and leg peripheral nerve injuries contribute largely to functional disability. These injuries seldom affect a single-line nerve; rather the injury goes beyond and disrupts the nerve tissue across multiple nerve paths. Here we investigate handcrafted PDMS based multi-branch nerve guidance conduit, which addresses this crucial branching from the sciatic nerve to aid with the regeneration to their appropriate distal targets. The design concept of the developed multiple branch nerve scaffolds is not specific for the sciatic nerve but can be modified for general use of all peripheral nerves and additional applications. Microchannels are also fabricated into a device in …

This study examined the delivery of information and services offered to grandparents who had become the primary caregivers of pre-k through third grade students to determine if the information and services were effective in decreasing chronic early absence as defined by Chang and Romero (2008). This mixed-method, multi-case study focused on the perceived needs of custodial grandparents and examined if the school system was meeting their needs through delivery of information and services. The researcher sought participation from 5 custodial grandparents who had grandchildren in pre-k, kindergarten, first, second, or third grades in a Northeast Tennessee school system and whose …

Influence Of Lactobacillus Rhamnosus Isolated From “Amabere Amaruranu” Cultured Milk On Adipogenesis, Justin E. Kotala

Electronic Theses and Dissertations

This study was performed to test the in vitro effects of a Lactobacillus rhamnosus isolate from “amabere amaruranu”, a traditional Kenyan cultured milk, on 3T3-L1 and Caco-2 cell lines. Cultures of fully mature 3T3-L1 adipocytes were treated with bacterial isolate cell extract (CE), filtered spent broth (FSB) from overnight bacterial culture, or with a PBS control. Expression levels of PPAR³1 and 2, C/EBP±, and ATGL proteins in 3T3-L1 cells were upregulated by FSB treatment. CE treatment did not affect protein expression levels. Expression of MTTP and SREBP-1c proteins in Caco-2 cells showed no change with either treatment. Optical density measurements …

The Lawrentian Woman: Monsters In The Margins Of 20th-Century British Literature, Dusty A. Brice

Electronic Theses and Dissertations

Despite his own conservative values, D.H. Lawrence writes sexually liberated female characters. The most subversive female characters in Lawrence’s oeuvre are the Brangwens of The Rainbow. The Brangwens are prototypical models of a form of femininity that connects women to Nature while distancing them from society; his women are cast as monsters, but are strengthened from their link with Nature. They represent what I am calling the Lawrentian-Woman.

The Lawrentian-Woman has proven influential for contemporary British authors. I examine the Lawrentian-Woman’s adoption by later writers and her evolution from modernist frame to postmodern appropriation. First, I look at the …

Painting With Turbulence, Chuqiao Wang

All Theses

Inspired by a study that identified a strong similarity between Vincent van Gogh's and Jackson Pollock's painting techniques, this thesis explores the interplay between science and art, specifically the unpredictable behaviors in turbulent flows and aesthetic concepts in painting. It utilizes data from a GPU-based air flow simulation, and presents a framework for artists to visualize the chaotic property changes in turbulent flows and create paintings with turbulence data. While the creation of individual brushstrokes is procedural and driven by simulation, artists are able to exercise their aesthetic judgments at various stages during a painting creation. A short animation demonstrates …

It is now widely accepted that focused efforts are needed for identifying the list of physicochemical descriptors of ENM before they can be …

Distillation Time As Tool For Improved Antimalarial Activity And Differential Oil Composition Of Cumin Seed Oil, Valtcho D. Zheljazkov, Archana Gawde, Charles L. Cantrell, Tess Astatkie, Vicki Schlegel

Department of Food Science and Technology: Faculty Publications

A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations were tested in this study: 5, 7.5, 15, 30, 60, 120, 240, 360, 480, and 600 min. Oil yields increased with an increase in the DT. Maximum oil yield (content, 2.3 g/100 seed), was achieved at 480 min; longer DT did not increase oil yields. The concentrations of the …

The Human Gut Mycobiome: Pitfalls And Potentials — A Mycologist's Perspective, Mallory J. Suhr, Heather E. Hallen-Adams

Department of Food Science and Technology: Faculty Publications

We have entered the Age of the Microbiome, with new studies appearing constantly and whole journals devoted to the human microbiome. While bacteria outnumber other gut microbes by orders of magnitude, eukaryotes are consistently found in the human gut, and are represented primarily by the fungi. Compiling 36 studies spanning from 1917 to 2015, we found at least 267 distinct fungal taxa have been reported from the human gut, and seemingly every new study includes one or more fungi not previously described from this niche. This diversity, while impressive, is illusory. If we examine gut fungi, we will quickly observe …

Background Differences In Baseline And Stimulated Mmp Levels Influence Abdominal Aortic Aneurysm Susceptibility, Matthew A. Dale, Melissa K. Suh, Shijia Zhao, Trevor Meisinger, Linxia Gu, Vicki J. Swier, Devendra K. Agrawal, Timothy Greiner, Jeffrey S. Carson, B. Timothy Baxter, Wanfen Xiong

Department of Mechanical and Materials Engineering: Faculty Publications

Objective: Evidence has demonstrated profound influence of genetic background on cardiovascular phenotypes. Murine models in Marfan syndrome (MFS) have shown that genetic background-related variations affect thoracic aortic aneurysm formation, rupture, and lifespan of mice. MFS mice with C57Bl/6 genetic background are less susceptible to aneurysm formation compared to the 129/SvEv genetic background. In this study, we hypothesize that susceptibility to abdominal aortic aneurysm (AAA) will be increased in 129/SvEv mice versus C57Bl/6 mice. We tested this hypothesis by assessing differences in aneurysm size, tissue properties, immune response, and MMP expression.

Methods: Mice of C57Bl/6 or 129/SvEv background underwent AAA induction …

The Neurobiology Of Circadian Rhythms, Patricia J. Sollars, Gary E. Pickard

School of Veterinary and Biomedical Sciences: Faculty Publications

Daily rhythms in nature, such as the opening and closing of flowers or our patterns of sleep and wakefulness and their association with the perpetual alteration of night and day, were recognized in antiquity although their origins were not questioned until the eighteenth century. The French Astronomer Jean-Jacques d’Ortous de Mairan conducted an investigation into whether the leaves of the Mimosa plant opened in response to light.¹ While de Mairan’s experiments were the first to question the origin of such daily rhythms, Augustin Pyramus de Candolle is credited with the first suggestion that they arose through an internal timekeeping …

A Synthetic Porcine Reproductive And Respiratory Syndrome Virus Strain Confers Unprecedented Levels Of Heterologous Protection, Hiep Vu, Fangrui Ma, William W. Laegreid, Asit K. Pattnaik, David Steffen, Alan R. Doster, Fernando Osorio

School of Veterinary and Biomedical Sciences: Faculty Publications

Current vaccines do not provide sufficient levels of protection against divergent porcine reproductive and respiratory syndrome virus (PRRSV) strains circulating in the field, mainly due to the substantial variation of the viral genome. We describe here a novel approach to generate a PRRSV vaccine candidate that could confer unprecedented levels of heterologous protection against divergent PRRSV isolates. By using a set of 59 nonredundant, full-genome sequences of type 2 PRRSVs, a consensus genome (designated PRRSV-CON) was generated by aligning these 59 PRRSV full-genome sequences, followed by selecting the most common nucleotide found at each position of the alignment. Next, the …
