The Effect Of Exercise On Cardiac Function And Doxorubicin Accumulation In Left Ventricular Tissue Of Rats, Brock Thomas Jensen

Dissertations

Doxorubicin (DOX) is an anthracycline antibiotic that has cytotoxic actions. The therapeutic use of DOX to treat a wide array of cancers is limited by a dose-dependent cardiotoxicity. Although DOX is known to have several adverse side-effects, acute and chronic cardiotoxicity have received the most attention as both may eventually lead to heart failure. While exercise has been shown to protect against DOX cardiotoxicity, a clear and consistent mechanism to explain its cardioprotective effects is lacking. High performance liquid chromatography (HPLC) is a valuable instrument that can be used to evaluate cardiac DOX accumulation. We hypothesized that a reduction in …

Camouflage: The Experiences Of Low-Income Business College Students, Scarlett Ponton De Dutton

Dissertations

This qualitative study shares the complex stories of two low-income business students who attend a flagship, public university as out-of-state students with the purpose of understanding, describing, giving voice to, and discovering insight from their experiences. Throughout U.S. Higher Education history, there is a pattern of limited participation of students from the lowest income quartile, which leads to little being known about the experiences of students from low-income cultures of origin. This culminates in the lack of voice that low-income students have in higher education as they navigate an environment of class privilege such as the specific university in this …

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 …

Psychometric Evaluation Of The Valued Living Questionnaire: Comparing Distressed And Normative Samples, David D. Cotter

Dissertations

The Valued Living Questionnaire (VLQ; Wilson, 2002) was created to measure the extent to which an individual contacts his/her chosen values, an important construct in Acceptance and Commitment Therapy (ACT; Hayes, Strosahl, & Wilson, 1999). The goal of the current study was to contribute to the psychometric evaluation of the VLQ by replicating and extending the first study of the VLQ’s psychometric properties conducted by Wilson, Sandoz, Kitchens, & Roberts (2010). In the present study, the VLQ was administered to a normative collegian sample (n = 171, M age = 19.32) and a distressed sample of collegians who were participating …

The Evolution And Development Of Wing Form, Body Size And Flight In Large- And Small-Bodied Fruit Bats (Artibeus Jamaicensis And Carollia Perspiciillata), Jason B. Shaw

Dissertations

Differences in developmental patterns important to diversification are produced through heritable variation of the onset/offset and timing of juvenile growth. As the size and shape of an organism changes during ontogeny, morphological, and behavioral components must adjust to accommodate proper function. This study explored the ontogenetic pathways of two closely related Phyllostomids differing in flight ability, body size, life history strategies, and developmental state at birth. We hypothesized that Artibeus jamaicensis and Carollia perspicillata will show ontogenetic differences that account for the diversification of morphological, body size, and behavioral patterns. Comparisons between the two species‟ flight development, growth rates, and …

Dissolved And Colloidal Element Transport Through The Coastal Transition Zone, Moo Joon Shim

Dissertations

There are several factors (e.g., hurricanes, floodplain, and anthropogenic sources) that could modify trace element behavior through the coastal transition zone (CTZ). However, there is still a lack of information about these variables in affecting trace elements in the CTZ. For this study, water samples were collected in the Pearl River (PR), Bay of St. Louis (BSL), and the Mississippi River plume to study the effects of these factors on trace element.

A possible effect of Hurricane Katrina on water quality was examined in the East Pearl River (EPR). Hurricane Katrina could have resulted in increased inputs of organic matter …

Latent Growth Modeling Of A Nutrition And Physical Activity Intervention, Alicia Dea Sample

Dissertations

The health, economic, and social impacts of physical inactivity and unhealthy dietary patterns are quite significant and evidenced by the fact that only 3-4% of American adults follow all the dietary advice recommended by the Dietary Guidelines for Americans (DGA; Kohatsu, Robinson, & Torner, 2004), and specific subpopulations, including the rural South, are affected even more drastically (McCabe-Sellers et al., 2007). Furthermore, the majority of the people in the United States do not currently meet recommended amounts of physical activity (PA) and have not since the mid 1980s (U.S. Department of Health and Human Services [USDHHS], 2008). To address the …

A new paradigm for utilization of mobile agents in a modular architecture for scientific simulation is demonstrated through a case study involving Monte Carlo simulation of low energy electron interactions with molecular nitrogen gas. Design and development of Monte Carlo simulations for physical systems of moderate complexity can present a seemingly overwhelming endeavor. The researcher must possess or otherwise develop a thorough understanding the physical system, create mathematical and computational models of the physical system’s components, and forge a simulation utilizing those models. While there is no single route between a collection of physical concepts and a Monte Carlo simulation …

A Moderational Model Investigating Child Temperament, Executive Functioning, And Contextual Predictors Of Externalizing Behaviors In Preschoolers, Ferne Arlene Pinard

Dissertations

Child externalizing behavioral problems (e.g., ADHD symptoms and aggressive behaviors) often appear early in life, are relatively stable, and are associated with maladaptive outcomes in many domains of functioning. Research has shown that, for a subset of children who demonstrate these early behavioral patterns, the course is often more pervasive and persistent. Consequently, a better understanding of externalizing behavioral problems during the preschool period is essential. The current study examined whether biologically-based correlates (i.e., child temperament and executive functioning/neurocognitive attention; EF/Attention) would moderate the relation between the contextual correlates (i.e., socioeconomic status and parenting practices) and externalizing behaviors (i.e., ADHD …

Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, Felicia Culver Thadison

Dissertations

Explanations of chemical phenomena rely on understanding the behavior of submicroscopic particles. Because this level is “invisible,” it is described using symbols such as models, diagrams and equations. For this reason, students often view chemistry as a “difficult” subject. The laboratory offers a unique opportunity for the students to experience chemistry macroscopically as well as symbolically. The purpose of this investigation was to determine how chemistry lab students explained chemical phenomenon on the macroscopic, submicroscopic, and representational/symbolic level. The participants were undergraduate students enrolled in an introductory level general chemistry lab course. Students’ background information (gender, the number of previous …

Differential Reinforcement Of Alternative Behavior In Preschool Settings: Evaluation Of A Pre-Teaching Component, Matthew William Legray

Dissertations

This current study investigated the effectiveness of pre-teaching behavioral expectations prior to the implementation of a differential reinforcement of alternative behavior (DRA) intervention. The ultimate goal of the intervention was to decrease inappropriate behavior while simultaneously increasing appropriate behavior. Intervention that included pre-teaching with DRA was compared to the implementation of DRA in isolation using single case methodology, and intervention data suggest clear differences in beneficial outcomes for each student. The current study offers preliminary data on the utility of pre-teaching behavioral expectations to students prior to intervention. By actually teaching appropriate replacement a behavior prior to intervention, students are …

Does Psychopathy Predict Desirability In Speed Dating Situations? A Social Relations Analysis, Kathleen Tucker Payne

Dissertations

Psychopathy is a multifaceted construct that can lead to a number of consequences including many that could interfere with interpersonal relations and romantic attractions. The speed-dating paradigm allows researchers to study various aspects of interpersonal relations. The present study examined how the two-factor structure of psychopathy, as measured by the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996), may influence evaluations of initial romantic attraction during speed-dating events. Factor I, or “fearless dominance,” is characterized by the affective and interpersonal aspects of psychopathy, whereas factor II on the PPI represents “impulsive antisociality” and is characterized by the more antisocial features …

Further Validation Of The Larson Driver Stress Profile, Michael Paul Moore

Dissertations

Much of the literature on unsafe driving has focused on studying the role of single variables (e.g., driving anger, sensation seeking, etc.) and the degree to which they may increase one’s propensity to engage in aggressive or otherwise risky driving behavior. However, it is becoming increasingly clear that motor vehicle accidents and accident-related behavior are sufficiently complex as to require the use of multiple predictors. The current study examined the psychometric properties of the Driver Stress Profile (DSP; Larson, 1996), a brief self-report scale designed to assess four variables of interest in the driving literature. The DSP and measures of …

Circadian Rhythm And Vigorous Activity: Do They Make A Difference In Executive Function?, Janie Sue Ryland

Dissertations

PL 107-110, the No Child Left Behind Act of 2001, a federally mandated accountability system based on standards, attendance, and dropout rates has forced educational leaders to explore new avenues of student improvement. Research suggests that all three factors are impacted by scheduling preferences that are relative to time of day. The aim of this study was to extend evidence of executive function as it is impacted by time of day and diurnal preference when exposed to vigorous exercise conditions. Data were collected from a sample that included 100 sixth graders (60 females and 40 males) during the spring semester …
