A link between posttraumatic stress disorder and health behaviors, such as exercise, alcohol, smoking, and caffeine has been suggested. However, it is unknown whether veterans with combat-related PTSD differ from combat veterans without PTSD and whether health behaviors change over the course of exposure therapy for PTSD or differ based on PTSD severity.

Show moreA link between posttraumatic stress disorder and health behaviors, such as exercise, alcohol, smoking, and caffeine has been suggested. However, it is unknown whether veterans with combat-related PTSD differ from combat veterans without PTSD and whether health behaviors change over the course of exposure therapy for PTSD or differ based on PTSD severity. This study examined the relationship between health behaviors and PTSD. More specifically, combat veterans with and without PTSD were compared across self-reported levels of alcohol use, smoking, exercise, and caffeine. Health behaviors of combat veterans with PTSD were compared before and after a 17-week treatment for PTSD. Results showed a significant number of participants decreased alcohol use at post-treatment by an average of eight drinks over 30 days, regardless of their PTSD severity level or amount of improvement in PTSD symptoms. No significant differences were found for other health behaviors.

Show moreCognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as a mediator between the relationship of moderate alcohol use and cardiovascular disease mortality, this study examined the potential mediating role of CRP between moderate alcohol use and cognitive performance in later life. Therefore, the primary goals of this thesis were to: (1) examine the relationship between moderate alcohol use and cognitive aging over time in a demographically representative, longitudinal survey of Americans over the age of 65, and (2) examine a potential biological mechanisms by which this putative relationship functions. The sample utilized for this study consisted of the ADAMS sample of the Health and Retirement Study (HRS), a longitudinal, cohort-style study on health, retirement, and aging conducted by the University of Michigan and supported by the National Institute of Aging. In order to assess the effect of moderate alcohol use as related to the rate of change in cognitive performance over time, a series of slope-intercept models were run. Logistic regressions and Kaplan-Meier survival analysis were used to examine predictors of dementia risk and time-to-diagnosis. Results indicated that moderate alcohol use was significantly associated with better baseline functioning across cognitive measures (p ?.05), but had no significant effect on rate of change over time. Next, structural equation models were employed to examine the effect of alcohol use on cognitive performance as mediated by CRP within each domain. Ultimately, results from this study did not support the hypothesized models. Following this, a logistic regression and survival analysis were conducted in order to assess the effect of moderate alcohol use on dementia diagnosis. Results of these analyses indicated that moderate users of alcohol develop dementia at lower rates, and later in life, than do abstinent older adults. Lastly, a structural equation model was run to evaluate the effect of alcohol use on dementia diagnosis as mediated by CRP. Primary findings did not support the hypothesized model. Overall, findings from this study suggest that moderate alcohol use is associated with better cognitive functioning among community-dwelling older adults, and these relative benefits appear to persist throughout later life. Moderate alcohol use may also be related to a slower rate and onset of dementia development. Future research should investigate alternate biological mechanisms relating moderate alcohol use and cognitive functioning in later life.

Set in the Deep South, this collection of poems thrives on lusty nights, hard love, and the twinge of memory. The voices within range from youthful to jaded as they speak across pages, flowing into one another to create a pain-body which ultimately seeks closure in relationships with objects, family, drugs, lovers, body parts, heroes, and setting. Tuned to the lyrical voices of poets Kim Addonizio, Lynn Emanuel, and Dorianne Laux, poems such as (")Learning Shapes,(") (")Things that Make Me Feel Cool,(") (")Can't Say Daddy, and (")Don't Miss Mississippi(") seek out what makes up a person as the collection continues to practice manipulation with language, tradition, and context in works like (")Pearl Necklaces(") and (")Golden Boy.(") Faithfully and sarcastically, these collected poems drive to the fuzzy edges of attachment and never come back.

Show moreFrailty is a well-established indicator of late-life decline and is accompanied by higher rates of comorbidity and disability. Meanwhile, an estimated 41% of adults over the age of 65 report consuming alcohol (-) an identified health risk and protective factor depending on dosage. Given that the demographic group of older Americans is projected to double by the year 2050, identification of frailty risk and protective factors is imperative. The goals of this thesis are to: (1) identify how varying levels of alcohol consumption relate to frailty, and (2) elucidate a possible mechanism that accounts for the relationship between alcohol consumption and frailty. A sample of stroke-free participants over the age of 65 was identified from the Health and Retirement Study. Study 1 utilized stepwise logistic regression models to identify predictors of prevalent frailty at baseline (2000), and of incident frailty 4, 8, and 12 years later. For both males and females, significant predictors of frailty at all years included age, depressive symptomatology, and medical burden score. In addition, BMI was a significant predictor of frailty for females at all years. With respect to alcohol use, results revealed that drinking 1-7 drinks per week had a protective effect for females at baseline (OR=0.50) and 12 years later (OR=0.75); however, no such protective effects were found for males. Given that extant research has identified CRP as a mediator between the relationship of moderate alcohol use and cardiovascular health benefits, Study 2 used a cross-sectional sample from the 2008 wave to examine the potential mediating role of CRP between moderate alcohol use and reduced frailty risk. Results from structural equation modeling support the hypothesized model that moderate alcohol is associated with less frailty, and that this relationship is partially mediated by CRP levels. Overall findings suggest that moderate alcohol use confers health benefits for females by reducing frailty risk and that CRP is one mechanism by which alcohol use may confer protective effects for frailty. These results provide a starting place in an effort to better understand the protective effects of moderate alcohol use and can assist in improving prevention and treatment efforts for older adults by preventing or prolonging the onset of age-related diseases. Future research should further examine the relationship between alcohol use and frailty and determine if CRP mediates the relationship between moderate alcohol use and other beneficial health outcomes.

Show moreAlthough social anxiety disorder is most often diagnosed during adolescence, few investigations have examined the clinical presentation of this disorder exclusively in adolescents. Prior studies have demonstrated that some clinical features of SAD in adolescents are unique relative to younger children with the condition. Furthermore, the extant literature on daily functional impairment in this population is limited. In this investigation, multiple areas of functioning were examined in adolescents with SAD (n = 16) and normal control adolescents (n = 14): specific social skills, subjective distress and physiological reactivity during one speech performance task and one social interaction task; alcohol use and expectancies; subjective and objective quality of sleep; and daily distressing social activities. No differences were observed in sleep actigraphy, self-reported sleep difficulties, alcohol use, or alcohol expectancies. Adolescents with SAD reported greater distress during both analogue tasks relative to NC adolescents. During the speech task, adolescents with SAD exhibited significantly greater speech latency (4.42 seconds vs. 1.75 seconds) and spoke significantly less (83.09 seconds vs. 167.75 seconds) than NC adolescents. Additionally, SAD participants manifested greater skin conductance during the speech task. During the social interaction, adolescents with SAD asked significantly fewer questions (2.20 vs. 7.07) and required significantly more confederate prompts (2.33 vs. 1.14) to stimulate interaction. Finally, adolescents with SAD reported more frequent anxiety-provoking situations in their daily lives and greater avoidance of these situations, including answering questions in class, assertive communication, and interacting with a group. The findings are discussed with respect to the current understanding of alcohol use, quality of sleep, and social functioning in adolescents with SAD.

Show moreWhat We Hide is a collection of memoir essays that explores the themes of mystery and deception in personal relationships, specifically within familial and romantic ones. Though the essays in the collection explore the decades from early in the narrator's childhood through her move to Florida for graduate school, the narrator's keen discernment of the world around her and her curiosity for what experiences shape a person's character remain constant. Many essays explore the extent of her father's alcoholism and the consequences of it, as well as the narrator's obsession over the possible sources of his addictions. Other essays examine the narrator's relationships with men beginning when she enters high school and question the extent to which her strained relationship with her father both excuses and/or explains the way she deceives and allows herself to be deceived in these relationships. What We Hide is endlessly implicating and looks for the accountability of these situations from all sources. The narrator delves into the sneakiness of her parents' courtship, the accusations that become commonplace during their divorce, the ways in which the narrator lies to family, friends, and boyfriends for her own selfish motives, and how each of these experiences shapes subsequent ones.What We Hide uses personal experience, emails, and newspaper articles to demonstrate the vulnerability, contradictions, and complications that are inherent in all of us as humans and how these weaknesses manifest themselves in the relationships with those we are closest with.

Show moreIreland is a country with a rich and unique cultural heritage. It is difficult to imagine that certain facets of Irish culture (e.g. Saint Patrick's Day, the Blarney Stone, or the Ring of Kerry) can ever be taken for granted since they are so widely recognized internationally. One common feature of Irish life that possibly warrants more scholarly attention is the public house or pub. Much has been written about pubs as quaint institutions in popular literature and fiction. Curiously, they remain largely overlooked as vital aspects of Irish culture by anthropologists and others in the social sciences. In many ways, socio-cultural research on pub life in Ireland is woefully under examined. In an effort to better evaluate the significance of traditional pub life to Irish culture, my thesis seeks to integrate and critically assess the existing socio-cultural literature on Irish pub life. Such work will not only help highlight both the commonalities and discrepancies within this area of study, it will more significantly identify those areas of Irish pub life that can benefit from further academic investigation. Two recent trips to Ireland in September 2004 and May 2006, allowed me to observe important aspects of pub life first hand. It became apparent from these encounters that, like the history of Ireland itself, local pubs have a rich historical foundation. Many of the pubs that I visited have been in existence or operational since the Middle Ages. Based on this longevity, one can reasonably argue that pubs in Ireland function largely as locales of social significance and cultural reproduction, not just centers of recreational drinking. Using my travel experience as a starting point for the critical analysis phase of this thesis project, I have developed three general research questions that I will explore to varying degrees in the context of this work. These are: (1) what are the origins of pubs in Ireland?; (2) what explicit and implicit functions do pubs serve in Irish communities?; and (3) what possible developments are likely to affect Irish pubs in the near and distant future?

Show moreThis study examined the effects of delay of gratification on academic success, substance abuse, and violent behavior. The participants in this study were chosen from an alternative learning school comprised of middle school students in Florida. The hypothesis for this study is as follows: Delay of gratification is negatively related to substance abuse and violent behavior, and positively related to academic achievement. The analysis of the data was conducted on the primary predictor variable (delay of gratification), alternate predictor variables (substance abuse and violent behavior) and the ultimate outcome variable (academic achievement) of this study. Initial statistical inquiry involved descriptive statistics (mean, standard deviation, kurtosis and skew) of the aforementioned variables, partial correlations (variable interrelationships), and the formulation of a multiple regression path analysis to investigate the particular paths individually within the proposed theoretical model (Wagner, 1993).

Show moreAdvertisements affect our daily lives and as technology and the practice of marketing has developed over the course of history, we have become exposed to greater amounts of product and service campaigns. The purpose of advertisements is to educate the consumer with the goal of ultimately selling the product, and many companies and organizations would not be able to survive without the use of advertisements. Ultimately, it is a necessity for a business to prosper in a competitive market, but there are possible side-effects for the consumer that are beyond the intentions to buy. The purpose of this thesis is to explore the effects advertisements play on the college student in particular. Different static/multi media advertisements have been shown to various college students ranging in gender and background to discover the comprehensive ramifications of specific promotions to study the moral and ethical impact that advertisements play on students' moral intent. An analysis and conclusion will be given, along with ideas for possible future studies. Recommendations will also be stated for marketers to be morally responsible for the advertisements they portray so the audience is not effected in a way that can lead to unwanted consequences. Ultimately, the results did not support the original hypotheses, leading to thought- provoking questions concerning our current marketing practices and the effectiveness of static and multimedia advertisements on college students. Future studies need to take place to reveal the accuracy of the study and to ultimately answer the question, "Are current advertisements influencing the audience at hand?"

Show moreThe use of heterogeneous catalysis is well established in chemical synthesis, energy, and environmental engineering applications. Supported Pt nanoparticles have been widely reported to act as catalysts in a vast number of chemical reactions. In this report, the performance of Pt/ZrO2 nanocatalyst for the decomposition of methanol, ethanol, 2-propanol, and 2-butanol is investigated. The potential of each alcohol for the production of H2 and other relevant products in the presence of a catalyst is studied. All the alcohols studied show some decomposition activity below 200°C which increased with increasing temperature. In all cases, high selectivity towards H2 formation is observed. With the exception of methanol, all alcohol conversion reactions lead to catalyst deactivation at high temperatures (T >250°C for 2-propanol and 2-butanol, T >325°C for ethanol) due to carbon poisoning. However, long-term catalyst deactivation can be avoided by optimizing reaction conditions such as operating temperature. In addition, the performance of Pt/γ-Al2O3 is evaluated in the oxidation of 2-propanol. Pt nanoclusters of similar size (~1 nm diameter) but different structure (shape) were found to display distinctively different catalytic properties. All the systems studied achieve high conversion (~ 90%) below 100°C. However, flatter particles display a lower reaction onset temperature, demonstrating superior catalytic performance. Acetone, CO2, and water are generated as products indicating that both partial and complete oxidation are taking place. A number of techniques including AFM, XPS, TEM, HAADF-TEM, XAFS as well as packed-bed reactor experiments were used for sample characterization and evaluation of catalytic performance.
