The Effects Of Stressors And Stress Hormones On Behavior, Physiology, And Disease Susceptibility In Terrestrial Salamanders, Christopher Fonner

Electronic Theses and Dissertations

Amphibians are exposed to numerous environmental stressors, which may contribute to population declines being experienced by amphibians worldwide. Upon exposure to stressors, animals will release the glucocorticoid hormone, corticosterone (CORT), which typically mediates physiological and behavioral responses for resisting or coping with the stressor. Additionally, amphibians are at risk from a chytrid fungal pathogen, Batrachochytrium dendrobatidis (Bd). After Bd infection, amphibians may develop the potentially fatal disease chytridiomycosis. To better understand how CORT mediates responses to different stressors, and possible immunosuppressive effects of CORT on Bd susceptibility, I performed several experiments. First, I tested the predation stress hypothesis in terrestrial …

Organizational Ethics For Sponsorship And Governance In Catholic Healthcare, Alex Garvey

Electronic Theses and Dissertations

Catholic healthcare in the U.S. is distinctive in its organizational structure insofar as it typically has Sponsorship as well as Governance oversight, reflecting the Catholic social tradition and organizational ethics to engage both patient care and the public good. Sponsorship deals with the mission and identity of Catholic organizations to ensure that they implement the Catholic social tradition. Governance deals with organizational ethics to ensure that the organization's values (reflecting its mission and identity) influence all aspects of the institution. Because these are intricately connected, the dissertation deals with them in an integrated manner, hence the combined focus upon Sponsorship …

An Interactional Analysis Of Adult Cognitive Assessment, William Hasek

Electronic Theses and Dissertations

Psychological tests often include a standardized protocol, which gives specific instructions to clinicians on how the tests are to be administered. This protocol is intended to minimize variation across test administrations, allowing the test to yield reliable and valid measurements. Clinicians are advised to adhere to the test protocol as closely as possible, though departures from protocol are often necessary, as many assessments require clinicians to clarify instructions, modulate client anxiety, and intervene to maintain the client's motivation. Protocols provide little guidance on how clinicians are to make these departures. The clinical literature on assessment contains some advice on when …

This study examined one particular technology, the Online Social Network (OSN), using Edmodo in light of how it is perceived as an instructional platform. Additionally, whether the OSN supports …

Predictors Of Harmful Sexual Behaviors In A Normative Population, Matthew A. Poinsett

Master's Theses and Doctoral Dissertations

In order to identify important predictors of high-risk and aggressive sexual behavior, this study examined the relationships between problematic sexual behavior, aberrant sexual experiences, family environment, parental monitoring, delinquency, and peer relatedness. Participants were 344 college students who completed the Comprehensive Sexual Experience Survey (CSES), an online questionnaire. High-risk behaviors, including possible victimization, were predicted by aberrant sexual experiences, family environment, delinquency, and parental monitoring. Regression analyses indicated that aggressive sexual behavior was associated with aberrant sexual experiences and delinquency. Examination of data across genders indicated significant differences between them, including men’s earlier initiation of masturbation and pornography use, higher …

Moral Courage: A Requirement For Ethical Decision Making In Nursing Home Leadership, Shelley Kobuck

Electronic Theses and Dissertations

Moral courage will no longer be an option for Nursing Home Administrators (NHA) to lead ethically with the projections for the future needs of healthcare services and the governmental involvement in containing the costs of care in the United States. The estimated increase in the 65 year and older population over the next 40 years and the accompanying impacts necessitate that healthcare will need to make significant changes from the care and services that currently exist. This growth in population of older adults will also be coupled with increased disability and declining resources. Due to these trends, persons in leadership …

Beyond Biology: Bases For A Child-Centered And Functional Account Of Parenthood, Jacob Kohlhaas

Electronic Theses and Dissertations

This dissertation argues that the presently influential Catholic theological account of parenthood is indebted to an essentialist theory of gender and the system of sexual ethical reasoning it produces. In consideration of the family, Catholicism tends to favor the differentiated gender roles of the father as the primary financial provider and the mother as the primary caregiver. Though such thinking is often justified as natural or traditional, it relies heavily upon a post-Victorian social context. This gender complementarity is often accompanied by an idealization of the autonomous biological-nuclear family. This family is autonomous in granting parents alone direct responsibility for …

Sin And The Story Of Salvation: The Theology Of Atonement In Light Of Biblical Narrative Theology, Mark Ortwein

Electronic Theses and Dissertations

Contemporary atonement theology offers three general conceptions of the cross: objective, subjective, and dramatic, which corresponds to Gustaf Aulén's classic tripartite typology. Although these different views are important since they contribute to a rich soteriology, when addressing the topic of atonement, or reconciliation proper, the objective type, promoted in satisfaction and penal substitution theories, are by comparison more compatible with Scripture when considering its larger narrative structure. This compatibility is attributable to the seriousness with which they construe the problem of sin that alienates humanity from God and places them in a predicament from which they are unable to extricate …

The Lived Experiences Of International Counselor Education Students During Their Field-Based Clinical Supervision In The United States Of The Lived Experiences Of International Counselor Education Students During Their Field-Based Clinical Supervision In The United States Of America, Abeer Rasheed

Electronic Theses and Dissertations

Supervision is an essential principle of the counseling field and a distinct intervention (Bernard & Goodyear, 2009). The primary goal of supervision is to provide counselor-in-training professionals with knowledge, support, and useful feedback; at the same time, it assures that attention is paid to the welfare of clients. Mandatory clinical supervision is a significant resource for counselors-in-training, and receiving supervision is considered essential to the professional development of master's-level students. Such is certainly the case for international students pursuing a master's degree in professional counseling. In the counseling field, however, the cultural differences that most often cause role ambiguity also …

A Constructive Account Of Children's Moral Agency Drawing On Thomas Aquinas's Theory Of Emotions, Ann Vinski

Electronic Theses and Dissertations

This dissertation makes the case that children are moral agents engaged with the morality of their communities without being morally accountable as adults. Contemporary Christian theological anthropology holds that children are fully human and in the image of God, and that they are already encountering good and evil in the world. Childhood is viewed as an essential part of human life and as something that perdures throughout a person's existence. Through their emotions, children are able to engage with, make meaning of, and respond to their surroundings, and these early emotional experiences help to shape each person for the whole …

Macrophage Cox-2 As A Target For Imaging And Therapy Of Inflammatory Diseases Using Theranostic Nanoemulsions, Sravan Kumar Patel

Electronic Theses and Dissertations

Personalized medicine can be an approach to address the unsatisfactory treatment outcomes in inflammatory conditions such as cancer, arthritis, and cardiovascular diseases. A common feature of chronic diseases is the infiltration of pro-inflammatory macrophages at the disease loci. Infiltrating macrophages have been previously utilized for disease diagnosis. These features suggest that macrophages can be broadly applicable targets for simultaneous therapy and diagnosis. Cyclooxygenase-2 (COX-2), an enzyme involved in the biosynthesis of a lipid inflammatory mediator, prostaglandin E2 (PGE2), is over expressed in macrophages infiltrating the pathological site. Inhibition of PGE2 leads to reduced inflammation, pain and macrophage infiltration. To utilize …

Communicating Through Cork: Marcel Proust's Performative Call To Philosophy Of Communication, David Deiuliis

Electronic Theses and Dissertations

Philosophy of communication replaces modernity's metanarrative of progress with postmodernity's many works in progress. The metanarrative of postmodernity is fragmentation, the lack of a metanarrative. In postmodernity, progress sputters and stalls, then starts on new paths. Philosophy of communication responds to fragmentation by converging the fragments of philosophy and communication. In his life and work, Marcel Proust (1871-1922) embodied the duality of philosophy of communication. Proust recognized the false grandeur behind the gold gilding of the Belle Epoque in nineteenth-century France, and reframed progress as a series of fits and starts, where the self follows false scents in a search …

Topographical Differences In Stress Vulnerability In Experimental Parkinson's Disease, Jessica M. Posimo

Electronic Theses and Dissertations

Parkinson's disease is characterized by the progressive spread of protein misfolding stress, or proteotoxicity, across the brain. During this protracted process, the allocortex of the temporal lobe develops protein inclusions before the neocortex in the frontal and parietal lobes. In the present study we tested the hypothesis that the staged appearance of proteotoxicity in allocortex followed by neocortex is the result of intrinsic vulnerability differences. We microdissected the neocortex and multiple subregions of the allocortex from rat brains and plated the primary neo- and allocortical neurons for parallel in vitro studies. Cells were then exposed to a number of Parkinson's …

From Their Own Voices: The Lived Experiences Of African Americans Exposed To Jim Crow, Janelle R. Carter

Electronic Theses and Dissertations

Researchers have become increasingly interested in the impact of racism on African Americans; however, because interactions involving racism are highly subjective, it can be difficult to assert the presence of trauma in a social science context. Thus, whereas literature regarding the effects of racism is abundant, few studies have explored the effects of being exposed to the laws of the "Jim Crow" era. This study sought to illuminate the lived experiences of African Americans who were exposed to the racial caste system known as Jim Crow. This inquiry looked at transgenerational trauma, exploring exposure to decades of legal discrimination, while …

Shear Wave Splitting Analysis Beneath Tien Shan: Geodynamic Implications Of Complex Anisotropy, Solomon Gerra Cherie

Doctoral Dissertations

"In spite of numerous studies, the mechanisms for the crustal shortening, mountain formation and associated tectonism leading to complex or simply seismic anisotropy formation beneath the Tien Shan Orogenic Belt is still debated. The most popular hypotheses suggested for the existence of seismic anisotropy are small-scale mantle convection, regional scale resistive basal shear and APM induced asthenospheric flow. Here, we used shear-wave splitting (SWS) measurements with good azimuthal coverage to provide additional constraints on the various models proposed by previous studies. One of the most effective approaches utilized to constrain convective mantle flow patterns is the splitting of P-to-S converted …

Reliability-Based Optimization Design Of Geosynthetic Reinforced Embankment Slopes, Michelle (Mingyan) Deng

Doctoral Dissertations

"This study examines the optimization design of geosynthetic reinforced embankment slopes (GRES) considering both economic benefits and technical safety requirements. In engineering design, cost is always a big concern. To minimize the cost, engineers tend to seek an optimal combination of design parameters among the considered alternatives while ensuring the optimal solution is safe. Reliability-based optimization (RBO) is such a technique that provides engineers the optimal design with the minimum cost while all technical design requirements are satisfied. The research goal of this study is to implement a mathematical formulation algorithm of the RBO technique in GRES design. To achieve …

Characterization Of Investment Shell Thermal Properties, Mingzhi Xu

Doctoral Dissertations

Thermal properties of investment casting shells have a great influence on the solidification of metal and thus control the properties of the cast product. Computational simulation requires accurate thermal properties to better represent the real process. Due to the porosity and meta-stable materials used in the investment shells, it is difficult to determine the real time thermal properties as a function of components and thermal processing history. Previous studies measured the thermal properties using a variety of methods, but very few results can be directly used in simulations due to lack of accuracy.

This research developed a new methodology that …

Effects Of N-Acetylcysteine Amide In Preventing/Treating Cataracts, Sri Krishna Yasaswi Maddirala

Doctoral Dissertations

"Cataract, the opacification of an eye lens, is a common pathological abnormality of the lens accounting for approximately 50% of all blindness. The only effective treatment currently available for a cataract is the surgical removal of the affected lens and replacement with an artificial lens for the restoration of vision. Although, cataract surgery is considered to be a very successful procedure in terms of visual outcome, the cost of surgery, need for trained personnel and surgeons, and postsurgical complications, limit the worldwide availability and accessibility of this procedure. Hence, alternative preventive and treatment procedures are worthy of investigation. The lens …

Analytical And Numerical Studies Of Photo-Injected Charge Transport In Molecularly-Doped Polymers, Amrita Roy Chowdhury

Doctoral Dissertations

"The mobility of photo-injected charge carriers in molecularly-doped polymers (MDPs) exhibits a commonly observed, and nearly universal Poole-Frenkel field dependence, µ ~ exp [square root (ß₀E)], that has been shown to arise from the correlated Gaussian energy distribution of transport sites encountered by charges undergoing hopping transport through the material. Analytical and numerical studies of photo-injected charge transport in these materials are presented here with an attempt to understand how specific features of the various models developed to describe these systems depend on the microscopic parameters that define them. Specifically, previously published time-of-flight mobility data for the molecularly …
