The Impact Of Adherence To Traditional Masculine Gender Role Norms On Anger And Depression, Matthew Charles Genuchi

Electronic Theses and Dissertations

Large scale studies of the incidence and prevalence of psychological disorders have consistently shown that women meet full DSM-IV criteria for major depressive disorder at twice the rate of men (Kessler et al., 1994; Kessler et al., 2003; NCS-R, 2007; Robins & Reiger, 1991). Some have proposed (Cochran & Rabinowitz, 2000; Kilmartin, 2005; Pollack, 1998) that the current DSM-IV diagnostic criteria do not adequately reflect the depressive symptoms of some men. Men tend to use more externalizing defenses and distracting coping styles to manage negative affect, and anger is hypothesized as an externalizing symptom of a masculine variation of major …

Electrohydrodynamic Atomization For Improved Macromolecular Drug Delivery, Michelle Zeles-Hahn

Electronic Theses and Dissertations

With advances in drug research, the use of biological therapeutics is becoming a reality. Unfortunately, methods for processing and delivering these fragile macromolecules often limit their therapeutic potential. For this dissertation, we explore the aerosolization of macromolecules by way of electrohydrodynamic atomization (EHDA) and how this method can be used to process and deliver therapeutics. EHDA employs a high voltage to break a column of liquid into drops. It was unknown if or how the residual charge left of the resulting droplets would affect lung cells. An in vitro experiment was conducted to spray aerosolized DNA, by way of EHDA, …

Investigating Instructors' Conceptions Of Evolution Through The Development Of The Classroom Test Of Evolutionary Reasoning, Patricia Eileen Palko

Electronic Theses and Dissertations

In order to assess the evolutionary understanding of high school biology teachers, an instrument entitled the Classroom Test of Evolutionary Reasoning (CTER) was developed. Content, response process, relations to another variable (the Conceptual Inventory of Natural Selection, or CINS), and internal structure evidence were compiled. The second version of the CTER was found to have adequate reliability and validity estimates to allow it to continue to be used as a measurement tool for an understanding of evolution. When assessing a sample of teachers (n = 724), the mean score was 6.35 out of a possible 13 points. The sample was …

A Pastoral Theology Of Congregational Care And Leadership: Nurturing Emergence, Carol P. Jeunnette

Electronic Theses and Dissertations

As with all bodies, congregational bodies experience challenges to their health, well-being, and ability to function as they desire. Problems in faith communities range from severe, intractable conflict to lethargy and decline, with far-ranging effects. The practice of offering pastoral care to individuals experiencing difficulties is rooted deeply in the Judeo-Christian tradition. There is, however, no explicit tradition of pastoral care for corporate congregational bodies experiencing difficulties. This dissertation draws on Bowen Family Systems Theory and its application by Edwin Friedman to congregations and leadership, in conjunction with aspects of process theology, to develop a pastoral theology of congregational care …

Neuronal Calcium Regulation And Cellular Stress In A Malignant Hyperthermia Disease Model, Jason Santiago

Electronic Theses and Dissertations

Calcium ions (Ca2+) are essential signaling molecules and must be carefully regulated to preserve specificity in function. One indispensible Ca2+ signaling protein is the ryanodine receptor (RyR) calcium release channel. RyR1 is essential for muscle contraction, and RyR1mutations can lead to severe muscle disorders such as malignant hyperthermia (MH). Recently, a mouse model of human MH (Y522S-RyR1) has been developed. In skeletal muscle, Y522S-RyR1 exhibits an increased sensitivity to activation resulting in Ca2+ leak, mitochondrial disorganization, and cellular stress. Although RyR1 expression is limited in the brain, the cerebellum may be particularly vulnerable to this disease because RyR1 is highly …

Constructing A Neuroscientific Pastoral Theology Of Fear And Hope, Jason C. Whitehead

Electronic Theses and Dissertations

Contemporary therapeutic circles utilize the concept of anxiety to describe a variety of disorders. Emotional reductionism is a detriment to the therapeutic community and the persons seeking its help. This dissertation proposes that attention to the emotion of fear clarifies our categorization of particular disorders and challenges emotional reductionism. I propose that the emotion of fear, through its theological relationship to hope, is useful in therapeutic practice for persons who experience trauma and PTSD.

I explore the differences between fear and anxiety by deconstructing anxiety. Through this process, I develop four categories which help the emotion of fear stand independent …

Male-To-Female Transsexual Individuals' Experience Of Clinical Relationships: A Phenomological Study, Karen M. Scarpella

Electronic Theses and Dissertations

This phenomenological study was designed to gain insight into male-to-female transsexual clients' experience of clinical relationships. Transsexual clients who enter into a clinical relationship have an experience that is unique due to their transsexual status in society. Their circumstances warrant attention in research due to the following factors: 1) the nature of being transsexual 2) the gate-keeping requirements necessary for transition 3) their experience in society as a vulnerable and oppressed population, and, 4) the importance of understanding the transsexual individuals' experience of clinical relationships from the perspective of transsexual clients themselves. Twelve transsexual women were interviewed using semi-structured format …

Electronic Theses and Dissertations

The purpose of this dissertation was to examine the effects of altered item order on attitude measures for both computerized adaptive and conventional survey formats. Based on items modified from a dissertation/thesis completion survey (Green & Kluever, 1997) with three scales, three survey versions were generated with items ordered by difficulty as hard-to-easy (H-E), easy-to-hard (E-H), and five medium trait level items presented first followed by randomly ordered items (M-R) for conventional survey format. Significant differences in item difficulty and item discrimination were found for two of the three scales. Differences in scale reliability were detected for the procrastination and …

Targeted Lipidomics: Analytical Strategies For Fatty Amides, Kristin Marie Kroniser

Electronic Theses and Dissertations

There are many significant compounds whose resting levels in biological systems are at nanomolar concentrations or below. In order to more effectively study these compounds work is being done to develop a completely automated system on a microchip. Several steps will be taken to start setting up this system because, at these low concentrations, detection is problematic for many current methods of analysis. First, develop a high performance liquid chromatography with mass spectrometry detection (HPLC/MS) method using atmospheric pressure chemical ionization (APCI) to detect primary fatty acid amides (PFAMs), one of the lipid classes of interest. Additives such as formic …

Aza-Bix(Oxazoline) Copper Complexes Immobilized Onto Self-Assembled Monolayers Supports: Surface Environment, Recycling, And Versatility Study, Christy Paluti

Electronic Theses and Dissertations

The design, effectiveness and versatility of the self-assembled monolayer-immobilized aza-bis(oxazoline) catalysts was explored here. The first part of this dissertation focuses on the immobilization of aza-bis(oxazoline) ligand with three different C2 groups onto self-assembled monolayer support material. In the homogeneous phase, the more steric bulk present at the C2 position of the catalytic system, the greater the selectivity. In the heterogeneous systems, those with the least amount of steric bulk had the greatest increase in selectivity compared to their respective homogeneous phase. The supports not only allowed for selectivity enhancements not observed in the homogeneous phase, but also demonstrated the …

Social Capital Influences In Women At Risk For Poor Pregnancy Outcomes, Jennifer James-Mesloh

Electronic Theses and Dissertations

Poor pregnancy outcomes such as prematurity, low birth weight and infant mortality are societal indicators of a nation’s health status. These indicators have remained at exceptionally high rates in the United States despite the levels of resources and technology. In the quest to understand that discrepancy, among the ranges of theories and models for explaining poor pregnancy outcomes an emerging concept is coming to attention: social capital. In order to test whether maternal social capital has an impact on pregnancy outcome, women in a Healthy Start program were surveyed over a 13-month period to assess their social capital levels and …

The Influence Of Sexual Selection On Behavioral And Physiological Mechanisms Underlying Reproductive Success In Male Cape Ground Squirrels (Xerus Inauris), Mary Beth Manjerovic

Electronic Theses and Dissertations

Sexual selection is considered a powerful evolutionary force responsible for the enormous diversity found in reproductive morphology, physiology, and behavior. I addressed questions related to selection in the Cape ground squirrel (Xerus inauris), a species characterized as highly social and promiscuous. These attributes often are responsible for variance in male reproductive success and as such, sexual selection theory predicts increased opportunity for sexual selection. I confirm that the predominant mechanism underlying genital evolution and competition for paternity in X. inauris is sperm competition. I find evidence that investment in sperm competition is costly and may reflect immunocompetence. I quantify reproductive …

"In My Heart I Had A Feeling Of Doing It": A Case Study Of The Lost Boys Of Sudan And Christianity, Kathryn Snyder

Electronic Theses and Dissertations

While members of the southern Sudanese Dinka tribe converted to Christianity in large numbers in the early 1990s, the Lost Boys, a largely Dinka group of young men who were separated from their families during the Sudanese civil war in the late 1980s, had a distinct conversion experience in refugees camps. Using first-person interviews and participant observation with a group of Lost Boys resettled in Denver, and historical and ethnographic data, this research seeks to explain why the Lost Boys converted to Christianity and the role that it played in their identity in refugee camps in Ethiopia and Kenya, and …

Mechanistic Importance Of Redox Potentials And Conformational Flexibility In Electron-Transferring Flavoproteins, Michael Anthony Swanson

Electronic Theses and Dissertations

The mitochondrial matrix flavoproteins electron transfer flavoprotein (ETF) and electron transfer flavoprotein-ubiquinone oxidoreductase (ETF-QO) are responsible for linking fatty acid β-oxidation with the main mitochondrial respiratory chain. Electrons derived from flavoprotein dehydrogenases are transferred sequentially through ETF and ETF-QO to ubiquinone and then into the respiratory chain via complex III. In this study, the effects of changes in ETF-QO redox potentials on its activity and the conformational flexibility of ETF were investigated.

ETF-QO contains one [4Fe-4S]^2+,1+ and one flavin adenine dinucleotide (FAD). In the porcine protein, threonine 367 is hydrogen bonded to N1 and O2 of the flavin ring …

Predictive Modeling Of Sulfide Removal In Tray Aerators, Jumoke O. Faborode

Electronic Theses and Dissertations

Hydrogen sulfide is commonly found in many Florida potable groundwater supplies. Removing sulfur species, particularly hydrogen sulfide is important because if left untreated, sulfide can impact finished water quality, corrosivity, create undesirable taste and odor, and oxidize to form visible turbidity and color. This document presents the results of a study designed to investigate the removal efficiencies of a variety of tray aerators in Central Florida in order to develop a predictive mathematical model that could be used to determine tray effectiveness for sulfide removal. A literature review was performed that indicated there was limited information regarding the removal of …

Results indicated …

Prehistoric Sandals Of The Southern High Plains: Indicators Of Cultural Affinity And Change, Allison N. Rexroth

Electronic Theses and Dissertations

Perishable artifacts, such as basketry, cordage, and sandals are rare cultural materials due to the environments in which they are preserved and their inherent non-durability. Where recovered, researchers have used them to study expressed identity and trace population movements over time and space. On this premise, previously un-described sandal assemblages from Trinchera Cave, Colorado and the Kenton Caves, Oklahoma/New Mexico were age dated, analyzed, and compared to other known sandal collections throughout North America, including Franktown Cave, Colorado. The study of the rare perishables from all three caves/rockshelters on the Southern High Plains have provided a unique opportunity for the …

Exploration Of The Meaning Of Depression Among Psychologists: A Quantitative And Qualitative Approach, Akira Murata

Electronic Theses and Dissertations

While depression is considered the most common mental illness regardless of age, gender, ethnicity, and socioeconomic status, compared to research on the general population, depression among psychologists has received little attention. However, as they are one of the major mental health care professionals, psychologists' mental health could greatly affect their clients' mental health, which raises competency and ethical concerns regarding their work as clinicians. In order to learn more about depression in this group, questionnaires were mailed to 800 randomly selected psychologists in the state of Colorado to examine the prevalence of depression among psychologists, how they dealt with their …
