Predicting Obesity From Four Eating Behaviors, Tovah Yanover

USF Tampa Graduate Theses and Dissertations

Obesity is a growing problem in the United States. Research into the causes, treatment, and prevention of obesity is vital. One past study examined four eating behaviors in relation to obesity: eating beyond satiety, snacking, night eating, and feeling hungry within three hours of eating. Only eating beyond satiety was associated with obesity. The present study examined these same eating behaviors while correcting some of the flaws of the previous study. Using a cross-sectional design, university undergraduates reported on the frequency of the above-named eating behaviors. Current weight and height were collected. Multiple regression analyses determined that eating beyond satiety …

"And So He Plays His Part:" Theatrical Prejudice And Role-Playing In As You Like It And King Lear, Erin Rutter

USF Tampa Graduate Theses and Dissertations

Although most critics affirm the importance of interior direction and role-playing in many of Shakespeares plays, there is a considerable disagreement concerning the result of this role playing: does it lead to positive growth or to degeneration? Moreover, this debate is often associated with the sixteenth-century controversy about the role of the theater in society. Some moralists insist that the theater can be an instrument for instilling virtue while others view the theater as sinful, debasing, and a catalyst to social breakdown. In this thesis, I will explore the antitheatrical prejudice in the early modern era and show how Shakespeare …

All industrial facilities within 11 broad categories of industry are responsible for self-identifying the need to comply with the Generic permit, and subsequently, implementing self-selected pollution prevention strategies. MS4 operators are required to identify and inspect “high risk” industrial and commercial facilities that may …

Exploring The Role Of Social Support In Heterosexual Women’S Use And Receipt Of Non-Lethal Intimate Partner Violence, Kathryn A. Branch

USF Tampa Graduate Theses and Dissertations

The concept of social support has been found to be a protective factor in women's intimate partner violence victimization. However, little is known about the relationship between women's social support and their intimate partner violence perpetration. Research evidence demonstrates that women's perpetration of violence is surprisingly frequent, particularly in women younger than age 30. This study investigated the role of social support in heterosexual women's use and receipt of non-lethal aggression against an intimate partner among 673 female college students. The implications of these findings for research and practice are discussed.

USF Tampa Graduate Theses and Dissertations

Varying theories have been presented about the relationship of emotional intelligence to transformational leadership. The present study examines the extent to which a self report measure of emotional intelligence, based upon an ability model, can predict each of the four components of transformational leadership. This study further considers the extent to which the quality of a leader-follower dyad's Leader-Member Exchange relationship can moderate the relationship between emotional intelligence and transformational leadership. Study results demonstrate that emotional intelligence is related to several components of transformational leadership, and that both the quality of the Leader-Member Exchange relationship and the tenure of the …

From Chapel To Chamber: Liturgy And Devotion In Lucantonio Giunta’S Missale Romanum, 1508, Lesley T. Stone

USF Tampa Graduate Theses and Dissertations

A missal is the liturgical book containing the prayers and readings for the celebration of the Mass. Originally designed in large folio format, the simultaneous arrival of the printing press amidst a shift in the celebration of Mass from a communal to a private sphere resulted in the proliferation of the small and more portable octavo-size missal. Missals traditionally contained minimal illustrations prior to printing, resulting in their strict classification as a liturgical object. This thesis questions the previous established boundaries which categorize medieval objects as related to a particular type of religious activity. In other words, missals have been …

The Early Ontogeny Of Feeding In Two Shark Species: Developmental Aspects Of Morphology, Behavior, And Performance, David C. Lowry

USF Tampa Graduate Theses and Dissertations

Early ontogeny is a time of rapid anatomical and behavioral development in most organisms. The degree of synchrony between form and function during this period, and the concomitant performance consequences, can strongly impact individual survival. Understanding the development of feeding during early ontogeny is important because nutrient acquisition universally influences organismal biology. A one-year, longitudinal feeding study was conducted for two elasmobranch species that were selected for their disparate morphology, behavior, and habitat: the whitespotted bambooshark Chiloscyllium plagiosum and the leopard shark Triakis semifasciata. To quantify changes in cranial morphology, external attributes of the feeding apparatus were measured weekly. …
