Biological Distance In Middle And Late Archaic Populations Of The Mid-South United States, Meadow Lea Campbell

Dissertations

This dissertation used osteometrics to assess the level of congruence between biological distance and long-distance material exchange in three Middle and Late Archaic groups living in the mid-South United States. Dental and cranial data support greater biological affinity between groups in southern Illinois (represented by individuals from the Black Earth site) and central Tennessee (individuals from Eva and surrounding sites) while groups in the Green River region of western Kentucky (Shell Mound Archaic) were somewhat more removed or perhaps more isolated. Females were more biologically variable than males for the majority of metrics used. This finding is suggestive of a …

Naturally Striated Muscle: Examining The Ideographic Crystallization Of, Dustin L. Briggs

Dissertations

In U.S. America and much of the Western world, natural is a venerated symbolic placeholder for any number of assumed virtues and ideals. Present conflicts have brought forward questions about what natural (which I argue functions as an ideograph) should mean in contexts that seem to call for a formal, enforceable definition. In this study, I use the vocabulary of Deleuze and Guattari (1987) and the context of bodybuilding to work towards a theory of how ambiguous ideographs become "striated" or “crystallized.” Within this discussion I present instances where natural has been employed as a vehicle to cause harm, and …

Rubrics As A Tool For Reaching Explicitly Evaluative Conclusions: Implications For Evaluation Theory, Training, And Practice, Krystin S. R. Martens

Dissertations

Evaluation is the systematic determination of merit, worth, or significance. A core professional evaluator competency is to provide transparent and explicit evaluative conclusions. Yet, “understanding the reasoning process to establish evaluative conclusions drawn in practice has to be the field’s greatest unmet challenge” (Fournier, 1995, p. 1). This three-article dissertation studies rubrics as a tool that can assist in meeting the stated challenge when used by program evaluators to reach explicitly evaluative conclusions.

Study 1 provides an account of the history and etymology of the term rubric and provides an analysis of peer-reviewed program evaluation literature, specific to the extent …

A Study On Sanguinarine As An Antileukemic Agent- Involvement Of Reactive Oxygen Species-Ceramide-Akt Apoptotic Signaling Pathway, Anees Rahman Cheratta

Dissertations

Dysregulation of apoptosis is a prime hallmark of leukemia. Therefore, drugs which restore the sensitivity of leukemic cells to apoptotic stimuli are promising candidates in the treatment of leukemia. The main objective of this dissertation was to examine the antileukemic effect of sanguinarine, in vitro, and to further examine the signaling mechanisms that may be involved. This study demonstrates that in human leukemic cells, sanguinarine activates a caspase-dependent apoptotic cell death pathway that is characterized by reactive oxygen species-dependent ceramide generation, and subsequent inhibition of Akt signaling pathway. In addition, sanguinarine also induces reactive oxygen species-dependent glutathione depletion and …

The Amino Terminal Region Of Cardiac Myosin Binding Protein-C Is Necessary For Cardiac Function, Thomas Lawrence Lynch

Dissertations

Cardiac myosin binding protein-C (cMyBP-C) is a thick filament-associated protein that has been suggested to regulate cardiac contraction via its amino terminal (N’) region. Following ischemic injury to the heart, cMyBP-C is cleaved into a predominant N’ fragment consisting of domains C0 through C1 and the first 17 residues of the M-domain that is referred to as C0-C1f. However, the necessity of the N’-C0-C1f region of cMyBP-C in regulating cardiac function in vivo has not been elucidated. I hypothesized that the N’-C0-C1f region of cMyBP-C is critical for normal cardiac function in vivo. To test this hypothesis, transgenic (TG) mice …

Mechanism By Which Commensal Bacteria Limit Inflammation, Mallory Paynich

Dissertations

Trillions of bacteria live within the gastrointestinal tract and are critical for maintaining intestinal homeostasis; however, the mechanisms utilized by specific bacterial molecules to contribute to homeostasis are not well understood. We utilize a mouse model in which a single oral dose of the probiotic, Bacillus subtilis, protects mice from acute colitis induced by the enteric pathogen Citrobacter rodentium. Our goal is to elucidate the mechanism by which B. subtilis prevents inflammation.

We identified exopolysaccharides (EPS) to be the active molecule of B. subtilis, and a single dose of EPS protects mice from disease. EPS binds F4/80+CD11b+ peritoneal macrophages, and …

Kant, The Natural Law, And The Question Of Normativity In Catholic Ethics, John Robert Crowley-Buck

Dissertations

This dissertation explores the question of normativity in 21st century Catholic ethical reflection. While, today, the natural law tradition frames and founds the normative question in Catholic ethics in terms of the imago Dei, this project explores the moral philosophy of Immanuel Kant and the challenge it presents to the natural law's claim to normativity. Specifically, this dissertation argues that in Kant's ethics, the normative question is answered in terms of the dignity of humanity, rather than the imago Dei, and that the dignity of humanity is a more relevant, shareable, and normative grounding for ethical reflection. To this end, …

The Relation Of Exposure To Community Violence To Self- Efficacy Based On Neighborhood, Family, And School Effects In A Community Sample Of Latino-American Youth, Arie Zakaryan

Dissertations

Latino youth and families are a burgeoning population in the United States, and many of whom live in neighborhoods exposed to community violence. Multiple contexts should be assessed identifying developmental assets youth use to adjust positively when exposed to violence. This study examines how different environmental contexts, i.e., home, school, neighborhood and acculturation, influence the relationship between exposure to community violence and self-efficacy for Latino youth. The current study uses an archival dataset of a larger longitudinal study (Project on Human Development in Chicago Neighborhoods). A confirmatory factor analysis …

The Impact Of Social Class Connectedness, School Belongingness, And Family Cohesion On Lower Class-Identified College Students, Kristen Eileen Adams

Dissertations

This study is one of the first to examine acculturative and enculturative factors as they relate to social class. Much of the extant literature surrounding acculturation and enculturation looks primarily at cultural factors such as race/ethnicity and/or immigration status. Due to the fact that social class is such a salient cultural identity in most individuals' lives and has a bearing on how one views and evaluates themselves in relation to others of differing social classes (Fouad & Brown, 2000), the purpose of this study was to examine the effects of social class connectedness on subjective wellbeing (including positive and negative …

School Nurse Perceptions And Decisions About Children Self-Carrying Inhalers In School, Lisa Anne Dominguez Jaurigue

Oxidative Stress In Avian Embyros, Toshi Tsunekage

Dissertations

Oxidative stress has been implicated in mediating trade-offs in the evolution of life histories. Oxidative stress results from an imbalance in the production of free radicals and an organism’s antioxidant defenses. Higher metabolic rates associated with more rapid growth and shorter development periods may increase oxidative stress and accumulated cellular damage in embryonic tissues. In my dissertation I explored oxidative stress and antioxidant defenses in avian embryos. I measured levels of oxidative stress in tissues of different stage embryos of Japanese quail (Coturnix japonica), and tested if patterns of lipid peroxidation could be explained by changes in the developing embryo’s …

Effects Of Resistance Exercise Training On Doxorubicin-Induced Cardiotoxicity, Keith B. Pfannenstiel

Dissertations

In recent decades cancer survivorship has steadily increased; however, the adverse side effects associated with chemotherapy treatment can diminish a patient’s overall quality of life. One of the most effective and widely used chemotherapeutic agents is doxorubicin (DOX). Though highly effective, its use is limited by a dose-dependent cardiotoxicity. While it is known that exercise preconditioning with endurance training models provide a cardioprotective effect to DOX treatment, little focus has been placed on the effects of a resistance training (RT) model on DOX-induced cardiac dysfunction. The purpose of the study was to determine the effects of a 12-week RT model …

Effects Of Exercise Training And Doxorubicin On Myogenic Regulatory Factors, Colin Joseph Quinn

Dissertations

Doxorubicin (DOX) is a widely used anthracycline antibiotic used to treat a number of hematological and solid tumor cancers. Dosage; however, is limited due to its toxic effects in healthy tissues. Negative consequences include myotoxicity in skeletal muscle, which may limit mobility and activities of daily living. The capacity for skeletal muscular regeneration relies heavily of the activity of myogenic regulatory factor (MRF) proteins. In vitro experiments with DOX depress expression of MRFs but in vivo treatment may elicit different responses. Endurance exercise has been shown to elevate MRF expression, and may preserve MRFs following in vivo DOX-treatment. Purpose: To …

The Transformative Experiences Of Female Educators As A Catalyst For Social Change In The World, April D. Jordan

Dissertations

As social justice issues become known, one may be moved to act in the hopes of alleviating the conditions that burden marginalized and oppressed people. What is sometimes missing from the discourse when discussing oppressive issues is the role women play in counteracting such subjugation. Also essential, yet missing from the research, are studies that underscore the importance of educators fostering social action change outside of and apart from institutions of learning and curriculum planning. This qualitative study examined the lives of six, nontraditional, female educator intellectuals whose perceptions of self (identity) and the world were transformed by engaging in …

Hospital Practices Related To Breastfeeding In Mississippi: A Socio-Ecological Approach, Amir Alakaam

Dissertations

Mississippi continues to have one of the lowest rates and the weakest support in respect to breastfeeding in the nation (Centers for Disease Control and Prevention, 2014a). Hospital practices supporting breastfeeding such as the Ten Steps to Successful Breastfeeding (TSSB) can dramatically increase breastfeeding rates and duration (Rosenberg, Stull, Adler, Kasehagen, & Crivelli-Kovach, 2008). The aim of this study was to explore breastfeeding practices in Mississippi hospitals based on two levels of the Socio-Ecological Model: the organizational level (phase I) examined the hospital practices based on the level of implementation of the TSSB; the individual level (phase II) examined knowledge …

Effects Of Resistance Training And Creatine Monohydrate On Doxorubicin-Induced Muscle Dysfunction, Eric Christopher Bredahl

Dissertations

Doxorubicin (DOX) is a powerful chemotherapy agent that is associated with a number of deleterious side effects, including skeletal muscle dysfunction. The exact mechanisms behind the observed skeletal muscle dysfunction have yet to be fully understood. Nonetheless, the observed myotoxicity is believed to be the result of an increased oxidative stress. Resistance training (RT) has been shown to preserve skeletal muscle function in DOX treated muscles. Conversely, creatine (Cr) has been shown to improve skeletal muscle function. Yet, there has been no investigation into the effect of combined RT and Cr on DOX-induced muscle dysfunction. Thus, the possibility exists that …
