Influence Of Maternal Thyroid Dysfunction On Infant Growth And Development, Ronee Elisha Wilson

USF Tampa Graduate Theses and Dissertations

Thyroid dysfunction is one of the most common endocrine disorders in women of childbearing age and the obstetric consequences of abnormal thyroid hormone levels during pregnancy have been established. Less understood is the implication of the presence of maternal thyroid autoantibodies on infant outcomes among women who are euthyroid during pregnancy. The objective of this study was two-fold: 1) to examine the influence of antenatal thyroperioxidase (TPO) status on fetal/infant brain and body growth measurements at delivery and 2) to explore the relationship of antenatal TPO status and maternal postpartum thyroid dysfunction (PPTD) on early infant growth and neurocognitive development. …

Stable Isotopes And Trace Elements In Tooth Enamel Bioapatite: Effects Of Diagenesis And Pretreatment On Primary Paleoecological Information, Jessica Norman Wilson

USF Tampa Graduate Theses and Dissertations

The geochemical analysis of bioapatite in vertebrate skeletal tissues is an important tool used to obtain ecological information from fossil animals. An important consideration when conducting stable isotope and trace element analyses is obtaining biogenic information that has been unaffected by diagenetic processes.

A two-step pretreatment procedure is commonly used remove diagenetically altered material by removing organic material, via an oxidation reaction with H2O2 or NaOCl, and secondary carbonate, via dissolution in dilute acetic acid, from bioapatite. While much work has been done to determine the efficacy of the pretreatment process, little research has been conducted to determine the potential …

Improving Implementation Of A Regional In-Line Chlorinator In Rural Panama Through Development Of A Regionally Appropriate Field Guide, Benjamin A. Yoakum

USF Tampa Graduate Theses and Dissertations

Access to safe drinking water has a direct effect on improving human health and their quality of life. One country still struggling with providing access to safe drinking water to all of its population is Panama. Panama's largest indigenous group, the Ngöbe people, is disproportionately affected by lack of access to safe drinking water. One way Panama's Ministry of Health (MINSA) is attempting to increase access to safe drinking water to the Ngöbe people is by disinfecting the water already captured by rural gravity fed water systems constructed within in the Ngöbe-Bugle reservation. This is accomplished using an in-line chlorinator …

Media And Usf Students' Perception Of Terrorism, Mamdoh Suleiman Al-Ameri

USF Tampa Graduate Theses and Dissertations

This study examined the influence of mass media on students' perceptions of terrorism by applying the situational theory of publics (Grunig & Hunt, 1984). Behavior is the consequence of perception of reality. But perception of reality is not always consistent with the reality itself. Because of the important role of the media in shaping perceptions, terrorist organizations rely on it to spread fear and advance their political goals beyond the people directly affected by their attacks. The media not only spreads the news of an attack, it contributes significantly to formulating and disseminating the message of terrorist organizations. This study …

A Comparative Study: How Educational And Healthcare Preparedness Affected Marketization Of The Chinese And Indian Economies, Cindy Arjoon

USF Tampa Graduate Theses and Dissertations

In this archival study, I explore reasons why India's economic takeoff into marketization in 1991 failed to meet the same success as China in 1979 when it made the same transition. I analyze the impact of education and healthcare on development and how investments in both sectors can yield significant returns privately and socially. The research in this paper seeks to answer the following question: Why was the Indian economy unable to meet the same success as China when developing a global, open market economy?

In order to answer this question, I begin by proving a solid relationship between education, …

Environmental Effects On The Biomechanics And Motor Physiology Of Elastically Powered Movements In Chameleons, Christopher Van Anderson

USF Tampa Graduate Theses and Dissertations

Environmental temperature exhibits profound effects on the activity and ecology of ectotherms through its impact on muscle contractile physiology. While the performance of locomotor behaviors powered by muscle contraction directly decreases by at least 33% over a 10°C drop in body temperature, chameleons are known to feed, presumably with high performance, at body temperatures where sympatric lizard species remain inactive. I propose that ballistic movements that are powered by the recoil of preloaded elastic and collagenous tissues are less thermally dependent than movements that rely on direct muscular power. Despite the reduced thermal sensitivity of the elastic-recoil powered movement, I …

A Comparative Perspective Of Black College Males On The Achievement Gap: Implications For School Counselors, Detra Bethell

USF Tampa Graduate Theses and Dissertations

The dominant discourse regarding Black males in America is that they are less academically successful than European American males and Black females. Similarly, Black males in the Bahamas are described as less successful than Black Bahamian females. School Counselors are in a unique position to alter the trajectory of success for Black males if they are knowledgeable of factors contributing to Black male academic success; have an awareness of the potential impact their unique roles can have; and develop and execute comprehensive, culturally responsive school counseling programs. While there is little research on the Achievement Gap in the Bahamas, much …

Synthesis And Investigations Of Type I And Ii Clathrates Of Group 14, Michael Blosser

USF Tampa Graduate Theses and Dissertations

Clathrates are a class of new materials that have an open-framework structure that allows guest atoms or molecules to be enclosed inside of their polyhedral framework. Varying the number, weight, and size of the guest species in a particular framework allows one to alter the physical properties of the clathrate. This relationship enables one to further the fundamental understanding of the physics and chemistry of the clathrate structure and use this knowledge to "tune" certain properties. This "tunability" of inorganic clathrates is of great interest as it allows one to optimize their physical properties; making them promising candidates for a …

Magnetism In Complex Oxides Probed By Magnetocaloric Effect And Transverse Susceptibility, Nicholas Steven Bingham

USF Tampa Graduate Theses and Dissertations

Magnetic oxides exhibit rich complexity in their fundamental physical properties determined by the intricate interplay between structural, electronic and magnetic degrees of freedom. The common themes that are often present in these systems are the phase coexistence, strong magnetostructural coupling, and possible spin frustration induced by lattice geometry. While a complete understanding of the ground state magnetic properties and cooperative phenomena in this class of compounds is key to manipulating their functionality for applications, it remains among the most challenging problems facing condensed-matter physics today. To address these outstanding issues, it is essential to employ experimental methods that allow for …

Effect Of Cement Chemistry And Properties On Activation Energy, Andre J. Bien-Aime

USF Tampa Graduate Theses and Dissertations

The objective of this work is to examine the effect of cement chemistry and physical properties on activation energy. Research efforts indicated that time dependent concrete properties such as strength, heat evolution, and thermal cracking are predictable through the concept of activation energy. Equivalent age concept, which uses the activation energy is key to such predictions. Furthermore, research has shown that Portland cement concrete properties are affected by particles size distribution, Blaine fineness, mineralogy and chemical composition. In this study, four Portland cements were used to evaluate different methods of activation energy determination based on strength and heat of hydration …

Factors Prospective Students Consider When Selecting An Mba Program, Lorie Plyler Briggs

USF Tampa Graduate Theses and Dissertations

This paper adds to existing literature regarding MBA selection processes and helps identify and better understand the needs that motivate consumers to pursue an MBA degree. Through a series of qualitative, one-on-one interviews with 17 brand-new MBA students or prospective students, this research found that while many people have "always wanted" to earn the advanced degree, most have toyed with the idea of a graduate business degree for many years. The most frequent reasons that people cite regarding their decision to seriously consider an MBA at a large southern university centers around four desires. These are, not surprisingly, the desire …

Nietzsche And Heidegger On The Cartesian Atomism Of Thought, Steven Burgess

USF Tampa Graduate Theses and Dissertations

My dissertation has two main parts. In the first half, I draw out an underlying presupposition of Descartes' philosophy: what I term "atomism of thought." Descartes employs a radical procedure of doubt in order to show that the first principle of his philosophy, the cogito, is an unshakeable foundation of knowledge. In the dialogue that follows his dissemination of the Meditations, Descartes reveals that a whole set of concepts and rational principles innate in our minds are never doubted. These fundamental units of thought are indivisible, distinct, and isolated, and enable the possibility of any rational demonstration. Atoms of …

Prediction Of The Performance Of A Flexible Footing On A Stone-Column Modified Subgrade, Justin Callahan

USF Tampa Graduate Theses and Dissertations

When foundations are designed on weak clay layers, it is a common practice to modify the subgrade by installing stone columns. Currently used methods for determining the level of ground modification, represented by the percentage of soil replaced (replacement ratio), assume a rigid foundation. These analytical methods provide the designer with the potential settlement reduction based on the compressibility parameters of the subgrade and the replacement ratio. The deficiencies of these methods are the assumption of rigidity of the foundation and the consideration of the settlement reduction as the only design criterion. Furthermore, they do not consider the effects that …

The Harm Of Influence: When Exposure To Homosexuality Elicits Anger And Punishment Tendencies, Timothy Andrew Caswell

USF Tampa Graduate Theses and Dissertations

In the current project, I examined the distinct elicitors and behavioral outcomes of anti-gay anger and anti-gay disgust. The CAD triad hypothesis (Rozin, Lower, Imada, & Haidt, 1999) suggests that anger and disgust are elicited by distinct moral violations and cognitive appraisals. A plethora of research has documented the strong link between disgust and sexual prejudice, but very little attention has been given to the role of anger in sexual prejudice. The biocultural framework of stigmatization (Neuberg, Smith, & Asher, 2000) suggests that people who counter-socialize against prevailing social norms are stigmatized by others. If homosexual sexual behavior does not …

Daily Recovery From Work: The Role Of Guilt, Eunae Cho

USF Tampa Graduate Theses and Dissertations

Acknowledging the critical role that occupational factors play in employee health, researchers have tried to understand ways to reduce the harmful effects of work on employee health. As the process by which individuals recharge resources that have been depleted, recovery has been recognized as important due to its potential to mitigate the negative effects of work on employee well-being. Although the recovery literature has continued to grow, many questions remain unanswered. The purpose of the present study was to expand our knowledge of recovery by examining situational (job characteristics) and individual (trait guilt) predictors of recovery and investigating psychological attributes …

A Study On Lane-Change Recognition Using Support Vector Machine, Weiping Deng

USF Tampa Graduate Theses and Dissertations

This research focuses primary on recognition of lane-change behaviors using support vector machines (SVMs). Previous research and statistical results show that the vast majority of motor vehicle accidents are caused by driver behavior and errors. Therefore, the interpretation and evaluation of driver behavior is important for road safety analysis and improvement. The main limit to understanding driver behavior is the data availability. In particular, a full-scale lane-change data set is difficult to collect in a real traffic environment because of the safety and cost issues. Considering the data demands of the recognition model development and the obstacles of field data …

Survivorship, Infertility And Parenthood: Experiencing Life After Cancer In Puerto Rico, Karen Elizabeth Dyer

USF Tampa Graduate Theses and Dissertations

While incidence rates are increasing for many cancers in Puerto Rico, mortality rates are declining (Torres-Cintron, et al. 2010), resulting in growing numbers of survivors and creating a situation in which long-term survivorship concerns are beginning to emerge as priorities. The importance of quality-of-life among survivors of cancer is increasingly being recognized among healthcare providers, although there remains a gap in knowledge of how young adult survivors cope with long-term treatment-related physical effects, such as infertility, and of the impact of cancer on survivors' social relationships and future goals.

Because understandings of "cancer survivorship," as well as of reproduction, vary …

The Efficacy Of Aggression Replacement Training With Female Juvenile Offenders In A Residential Commitment Program, Jody Anne Erickson

USF Tampa Graduate Theses and Dissertations

Female adolescents are increasingly being charged with crimes of violence, and the literature is lacking as to how best to reduce their aggressive tendencies. In the past, girls represented a small portion of all youths involved in criminal justice systems, and studies involving effective treatment options for them were rarely conducted.

Aggression Replacement Training® is a 10-week, evidence-based, group treatment intervention designed to advance moral reasoning, improve social skills, and manage angry feelings. Numerous outcome studies of Aggression Replacement Training® with both offending and non-offending male adolescents and with male and female adolescents together have yielded mixed results.
