Do State Regulatory Institutions Matter: Using Network Theory To Explore Linkages Between Air Policy Boards And Pollution Outcomes, Debra Jacobs Jun 2009

Do State Regulatory Institutions Matter: Using Network Theory To Explore Linkages Between Air Policy Boards And Pollution Outcomes, Debra Jacobs

Theses and Dissertations

The purpose of this study is to test an adapted model of network theory against state air pollution control institutions. Air pollution control presents a regulatory problem that has interstate, intrastate and multiple federal dimensions. It is one of extreme complexity and uncertainty, from both a regulatory and scientific perspective. The changing political environment federally has enabled states to redefine their roles in the regulatory process (Adler, 1997; Krane, 2007). Drawing from network theory in intergovernmental policy processes my research tests three key factors in explaining state air pollution levels: tenure in office of the air policy administrator, the use …

Expressive Writing With University Students With Disabilities, Geraldine Lotze Jun 2009

Expressive Writing With University Students With Disabilities, Geraldine Lotze

Theses and Dissertations

Research suggests college students with high incidence disabilities experience more distress than their peers without disabilities as they adapt to college. The expressive writing paradigm developed by Pennebaker and Beall (1986) effectively reduced distress in college students and other nonclinical samples when participants wrote about emotions they experienced surrounding an upsetting event. Previous research on expressive writing has not addressed the effectiveness of the paradigm with students with disabilities. A randomized control trial study examined changes in distress and daily hassles for participants with disabilities who engaged in expressive writing compared to a control condition in which participants wrote about …

“Design And Synthesis Of Molecular Probes For The Study Of 5-Ht2a And H1 Receptors”, Jitesh Shah May 2009

“Design And Synthesis Of Molecular Probes For The Study Of 5-Ht2a And H1 Receptors”, Jitesh Shah

Theses and Dissertations

The serotonin (5-HT) receptors, with seven subtypes and at least fifteen distinct members, mediate a wide range of physiological functions both in the central nervous system and in the periphery. All members of the 5-HT family except the 5-HT3 subtype belong to the family of aminergic G protein-coupled receptors (GPCRs). Over the years, various molecules have been reported which act selectively at 5-HT2 receptors. However, there are no ligands that exhibit complete selectivity for one subpopulation of 5-HT2 receptors. Insight into how drugs bind to 5-HT2 receptors could contribute significantly to the development of subtype-selective agents with enhanced therapeutic effects. …

Development Of Ppar-Γ Receptor Agonists As Therapeutic Agents For Diabetes, Ashwini Goswami May 2009

Development Of Ppar-Γ Receptor Agonists As Therapeutic Agents For Diabetes, Ashwini Goswami

Theses and Dissertations

The peroxisome proliferator-activated receptors (PPARs) are the transcriptional regulators of glucose, lipids and cholesterol metabolisms. It has been established that PPAR-γ is the receptor for thiazolidinediones (TZDs) class of type II anti-diabetic drugs. These compounds act as agonists of PPAR-γ. They may delay the development of type II diabetes in individuals at high risk of developing the condition, and have been shown to have potentially beneficial effects on cardiovascular risk factors. PPAR-γ receptor activation by TZDs improves insulin sensitivity by promoting fatty acid uptake into adipose tissue, increasing production of adiponectin (responsible for glucose regulation and fatty acid metabolism) and …

Does Mindfulness Reduce Negativity Bias? A Potential Mechanism For Reduced Emotional Distress, Laura Kiken May 2009

Does Mindfulness Reduce Negativity Bias? A Potential Mechanism For Reduced Emotional Distress, Laura Kiken

Theses and Dissertations

The present research examined if mindfulness reduced negativity bias on measures of attitude formation and cognitive style, as a potential explanation for the beneficial effects of mindfulness on emotional disturbance. Two studies were conducted. Study One was correlational and found that trait mindfulness inversely correlated with measures of negative cognitive style, and that the latter partially mediated an inverse association between mindfulness and predisposition to depression and anxiety. Further, correlations between mindfulness and both positive attitude formation and optimism hinted at a potential positivity bias. Study Two extended these findings using a randomized experimental design comparing a mindfulness induction to …

Creative Insubordination, John Henry Blatter May 2009

Creative Insubordination, John Henry Blatter

Theses and Dissertations

In today’s lexicon a ‘Daily Constitutional’ usually refers to a daily walk. But in actuality, a ‘Daily Constitutional’ is something that one does on a daily basis that is beneficial to one’s constitution or healthful(1); and one’s constitution being the aggregate of a person’s physical and psychological characteristics(2). With this definition, the daily constitutional refers to any daily activity that improves a person’s physical or mental health. At various stages in my life I may have understood my constitutional to be any number of things and it was not until I came into my own did I truly discover my …

How Does Mothers' Depression Influence Adolescents' Aggression? The Role Of Parenting, Family Functioning, And Informant Discrepancy, Kelly Pugh May 2009

How Does Mothers' Depression Influence Adolescents' Aggression? The Role Of Parenting, Family Functioning, And Informant Discrepancy, Kelly Pugh

Theses and Dissertations

Previous research has found that maternal depression is predictive of adolescents’ aggression. The present study examined three mechanisms believed to account for this relation: parenting practices, family functioning, and informant discrepancy. The data for this study are from the Multisite Violence Prevention Project which collected data from a high-risk sample of sixth grade students, parents, and core teachers. A within-subjects analysis of variance examined the association between maternal depression and informant discrepancy. Structural equation modeling compared the relation between maternal depression and adolescents’ aggression as a function of parenting practices and family functioning. Results indicated that maternal depression was related …

Physical Activity, Physical Fitness And The Psychosocial Well-Being Of Obese Adolescents, Nichole Kelly May 2009

Physical Activity, Physical Fitness And The Psychosocial Well-Being Of Obese Adolescents, Nichole Kelly

Theses and Dissertations

Overweight and obesity are associated with an array of negative physical and psychosocial symptoms in adolescents. Numerous pediatric obesity interventions have emerged in an attempt to address this significant public health concern. However, few have focused on African American females, a particularly high risk group for negative health behaviors and associated complications. Moreover, research examining the psychosocial changes associated with increases in physical activity and fitness, although promising in elder and adult populations, is nearly nonexistent in adolescents. Thus, the current study addressed limitations in the research and examined the psychosocial outcomes of adolescent participants in T.E.E.N.S., a culturally sensitive, …

The Dismissive Actually, Alexander Egner May 2009

The Dismissive Actually, Alexander Egner

Theses and Dissertations

This project is about giving in to the impulse of ideas. My mind is a little messy and cluttered, swirling with bits of stimuli. The spark of an idea happens when the bits collide. I prefer not to initiate or control the process so much as keep it fed and active. Through graphic design, I bear witness to these ideas, giving them form as a series of visible, tangible objects. Viewed comprehensively, the work establishes an ongoing chronicle of my creative life and mind.

Determinants Of International Long-Distance Eldercare: Evidence From Ghanaian Immigrants In The United States, Stephen Kodwo May 2009

Determinants Of International Long-Distance Eldercare: Evidence From Ghanaian Immigrants In The United States, Stephen Kodwo

Theses and Dissertations

Studies of Ghanaians who have immigrated to the United States indicate that both economic and emotional support continue to be provided to non-migrant families in Ghana. However support to “family relatives” has been studied generally, without specifying age. Thus, relationships between immigrants and their elderly relatives, particularly those who may be frail and vulnerable, have not been the focus of previous research. In addition, it is necessary to examine the dynamics that shape attitudes towards elderly people, and which in turn influence eldercare patterns among Ghanaian immigrants. Based on the literature, the researcher identified four factors relevant to international long-distance …

Understanding Death Anxiety In Women With Gynecologic Cancer, Hana Kim May 2009

Understanding Death Anxiety In Women With Gynecologic Cancer, Hana Kim

Theses and Dissertations

For most of us, thoughts about our own mortality are largely unconscious, an invisible backdrop to our daily living. However, when forced to face a potentially life threatening event, these otherwise underlying thoughts about human transience rise to consciousness. Given the seemingly inherent link between receiving a cancer diagnosis and developing an increased awareness of one’s own mortality, the present study sought to address the following research question, “What are the experiences and processes by which women with gynecologic cancer construct meaning and manage death anxiety in the face of their cancer diagnosis?” Based on an interpretive grounded theory paradigm, …
