Precision Synthesis Of Functional Materials Via Raft Polymerization And Click-Type Chemical Reactions, Joel Diez Flores

Dissertations

The need to tailor polymeric architectures with specific physico-chemical properties via the simplest, cleanest, and most efficient synthetic route possible has become the ultimate goal in polymer synthesis. Recent progress in macromolecular science, such as the discoveries of controlled/“living” free radical polymerization (CRP) methods, has brought about synthetic capabilities to prepare (co)polymers with advanced topologies, predetermined molecular weights, narrow molecular weight distributions, and precisely located functional groups. In addition, the establishment of click chemistry has redefined the selected few highly efficient chemical reactions that become highly useful in post-polymerization modification strategies. Hence, the ability to make well-defined topologies afforded by …

Utility Of The Inventory Of Callous-Unemotional Traits In Adolescent Offenders And Non-Offenders: An Item Response Theory Analysis, Lisa Laurence Ansel

Dissertations

The current study utilized Item Response Theory (IRT) analyses to examine the item functioning of the Inventory of Callous-Unemotional Traits (ICU; Frick, 2003) in the assessment of psychopathy-linked traits in adolescents. Self-report psychopathy measures, such as the ICU, have become increasingly common for use with adolescents. However, questions remain regarding their reliability and utility for accurately assessing these traits (Poythress, Dembo, Wareham, & Greenbaum, 2006). IRT analyses offer unique methods of investigating test and item functioning in regards to the underlying trait an inventory purportedly assesses. The current study examined and compared the item functioning of the ICU for the …

An Electrophysiological Investigation Of The Cognitive Processes Underlying Provoked Aggression In Humans, Jennifer Renee Fanning

Dissertations

Recently, the event-related potential (ERP) technique has been applied to questions of social information processing. Several studies have examined standard and social information processing variables in aggressive individuals, but little is known about the neurophysiological processes that take place in real-time during an aggressive encounter. In this study, 48 men and women high and low in aggression history exchanged noise blasts of varying intensity with a (fictitious) opponent in a modified version of a well-validated laboratory-controlled behavioral measure of aggression, the Taylor Reaction-time Task (Taylor, 1967), while ERPs were simultaneously being recorded at scalp sites. Mixed model ANOVAs were used …

This biographical study focuses on three of his piano compositions: Second Sonata, Eclipse II, and Go-Hyang. Each work represents one of three distinct compositional periods: the first reflects the influence of Prokofiev and features characteristics of the neoclassicism; the second marks a turn to experimentalism, atonality, and serialism; and the final indicates the return to a more traditional style that makes use …

The Lived Experiences Of 3rd Generation And Beyond U.S.-Born Mexican Heritage College Students: A Qualitative Study, Richard Galvan Edd

Dissertations

The purpose of this study was to describe the psychosocial and identity challenges of 3rd generation and beyond U.S.-born (3GAB-USB) Mexican heritage college students. Alvarez (1973) has written about the psychosocial impact "hybridity" can have on a U.S.- born (USB) Mexican individual who incorporates two distinct cultures (American and Mexican) in order to succeed in U.S. society, and yet, few empirical data is available beyond the 1st and 2nd generation on USB Mexican college students. As an example, there is no mention in the literature of two distinct and different worldviews present between immigrant and 3GAB-USB Mexican college students, which …

Examining The Effect Of Changes In The Peer Group On Attitudes: A Longitudinal Study, Dena C. Carson

Dissertations

Peer interactions are an important part of adolescence and have been the focus of much research in both psychology and criminology. The relationship between peer behavior and a youth’s own behavior has been demonstrated multiple times in prior research. Little is known, however, about how peer behavior may affect individual attitudes. This is surprising given that many prevention programs, particularly skills building programs, focus on changing and shaping individual attitudes to change/prevent behavior. This dissertation partially addressed this gap by focusing on the relationship between peer behavior and individual attitudes. This dissertation accomplishes three main goals through the use of …

The Economy-Crime Relationship Revisited: The Significance Of Recent Macroeconomic Conditions And Social Policy Changes For Child Poverty And Youth Violence Trends, White Nicole

Dissertations

The relationship between economic deprivation and violent crime has been one of the most widely studied in the field of criminology, yet little is known about the impact of recent macroeconomic conditions and welfare reform policies on the poverty-youth violence relationship. Therefore, the current study utilizes data from the 1993-2004 National Crime Victimization Survey to assess the association between poverty and youth violent victimization trends variously disaggregated by race, ethnicity, and family structure, and the impact of welfare reform and macroeconomic conditions on this relationship. In addition, the potential impact of welfare reform on the individual-level relationship between poverty and …

Construct Validation Of Political Skill, Katie Thenhaus

Dissertations

Social effectiveness is critical to mastering social interactions and “office politics”, however there is ambiguity in defining these social effectiveness constructs, in particular, political skill. The purpose of the present study was to investigate the construct validity of political skill utilizing a partial multitrait multimethod approach. The participants were undergraduate students with substantial work experience. Discriminant validity was examined with measures of political skill, emotional intelligence, self-monitoring, and social skill. Convergent validity was assessed with independent interpersonal sensitivity and behavioral measures of political skill. The results indicated a lack of construct validity evidence for political skill, with significant overlap among …

The Role Of Amyloid-Beta Assembly State In Monocyte Maturation And Smooth Muscle Cell Degeneration, Nikkilina Renee Crouse

Dissertations

Alzheimer's Disease (AD) is a progressive, neurodegenerative disorder which is ranked as a leading cause of death among Americans. AD is characterized by the presence of intracellular neurofibrillary tangles and extracellular plaques made of amyloid ß (Aß). Together these pathologies lead to severe memory impairment in patients, but research has implicated the presence of the Aß deposits as likely causes for AD progression. Aß is produced through the proteolytic cleavage of the integral membrane amyloid precursor protein, which occurs through the action of beta- and gamma-secretases and produces 39-43 amino acid Aß peptides. In AD, the Aß plaques are comprised …

Crisis In Education: A Call To Act, Debra Walker Emery

Dissertations

The current education system in the United States is riddled with difficulties which include an increasing demand for qualified teachers and persistently high attrition rates. Teachers are prone to low job satisfaction, low self-efficacy, as well as increased stress and burnout. Although these problems are widely discussed in the literature, scant intervention research is available. Additionally, existing interventions miss two key elements that may be especially relevant to the challenges faced by educators: acceptance and values. The current study examined the efficacy of acceptance and commitment therapy (ACT) for reducing teacher burnout through a day-long professional development workshop. Thirty-five teachers …

Person-Organization Fit As A Barrier To Employee Creativity, Angela M. Farabee

Dissertations

The relationship between person-organization fit (PO fit) and creativity was investigated in this study. Based on the attraction-selection-attrition framework (Schneider, 1987), over time organizational members become more homogeneous (e.g., on cultural values) which may be less conducive for individual employee creativity. Person-organization fit, defined as congruence on the non-creativity values from the competing values model (Quinn, 1988), was hypothesized to negatively relate to creativity. This had partial support for internal processes value fit when considering individuals in a low creative culture, otherwise it was unsupported. It was also hypothesized and moderately supported that fit on creativity/innovation value would be positively …

Quality Of Life In Patients With Non-Cardiac Chest Pain: The Impact Of Psychiatric Disorder Severity, Fear Of Pain, And Pain Catastrophizing, Katherine Elizabeth Hadlandsmyth

Dissertations

Patients who present in medical settings with persistent chest pain in the absence of identifiable cardiac cause (Fleet & Beitman, 1997) may be diagnosed with non-cardiac chest pain (NCCP). NCCP is a common, costly condition that may result in impaired quality of life (e.g., Eslick et al. 2003; Wong et al., 2002). Theories of NCCP (Mayou, 1998; White & Raffa, 2004) suggest that patients who react to NCCP with fear and thoughts of catastrophic consequences may avoid activities that elicit cardiac sensations. The daily behavioral impact of avoiding cardiorespiratory cues may limit quality of life due to activity avoidance. The …

An Investigation Of Data Protection And Computer Security In Small Irish Medical Practices, Sean Mcgrath

Dissertations

Small medical practices store and process the health information of their patients in order to aid in providing care to them. Because of this a level of trust exists between the patients and the practice to ensure the sensitive medical data is kept private and secure. There was no formalised way to test if this trust was well deserved and what level of protection was applied to such sensitive health records. A security model that is applicable to small medical practices for the purpose of protecting and securing the personal health information they store was constructed and validated by a …

Maternal Posttraumatic Stress Disorder, Parenting, Family Functioning, And Child Outcome, Desiree Alana Sutherland

Dissertations

Although a good deal of research has been conducted examining the effects of parental psychopathology of various types (i.e. maternal and paternal depression and schizophrenia, paternal PTSD), very few studies have investigated the influence of maternal PTSD on mothers’ parenting and their children’s behavioral and psychological functioning. This paucity of research is in spite of the fact that women exhibit higher lifetime PTSD prevalence rates than men. The current study examined the influence of maternal PTSD and trauma on mothers’ parenting, family functioning, and children’s psychological well-being in a sample of 125 mothers and 34 mother-child dyads. Mothers provided self-report …

Does Scheduling Matter? An Analysis Of A New High School Academic Schedule Policy And Its Impact On Attendance, Discipline And Academic Achievement, Carletta Denise Washington

Dissertations

ABSTRACT The purpose of this exploratory study was to analyze a Missouri school district’s newly adopted academic schedule type policy. The school’s new traditional academic schedule type replaced its previous block academic schedule type, effective for the 2005–2006 school year. This study reviewed the effectiveness of the policy change by analyzing the impact of each of the high school’s academic schedule types, block and traditional, on the high school’s targeted areas of student concern: attendance, academic achievement, and discipline incidents over a period of ten academic terms, 2000–2001, 2001–2002, 2002–2003, 2003–2004, 2004–2005, 2005–2006, 2006–2007, 2007–2008, 2008–2009, and 2009–2010.

Interoceptive Fear And Pain Anxiety In Non-Cardiac Chest Pain: Is Fear Associated With Reduced Physical Activity?, Jennifer Marie Craft

Dissertations

Non-cardiac chest pain (NCCP) describes angina-like pain suffered by patients who lack a cardiac diagnosis (Fleet & Beitman, 1997). Despite a benign diagnosis, some NCCP patients continue to experience persistent pain, cardiac worry, impaired quality of life (Eifert, Hodson, Tracey, Seville, & Gunawardane, 1996), elevated rates of psychiatric disorders (Bass & Wade, 1984; White, et al., 2008), and negative health consequences (Eslick & Talley, 2008). Consistent with theory, research indicates that NCCP patients differentially fear cardiac sensations (Aikens, Zvolensky, & Eifert, 2001; White, Craft, & Gervino, 2010). It may be that NCCP patients avoid physical activity, which elicits feared cardiorespiratory …
