A dramatic decline in physical activity levels occurs from adolescence to young adulthood. Those who were sedentary as adolescents tend to maintain a sedentary lifestyle. Women are particularly vulnerable to the effects of a sedentary lifestyle because of the risk for cardiovascular disease. The purpose of this research was to test a theoretical model of exercise in adolescent and young adult women using the theory of unpleasant symptoms with social cognitive variables and then to test a revised model that was determined a priori. The central hypotheses were that the relationships as depicted in the proposed theoretical models would be …


Socio-Natural Landscapes In The Palmarejo Valley, Honduras, James R. Hawken Apr 2007

Socio-Natural Landscapes In The Palmarejo Valley, Honduras, James R. Hawken

USF Tampa Graduate Theses and Dissertations

Communities have traditionally been viewed as spatially bounded social units composed of multiple households whose inhabitants are integrated by shared resources and a common sense of identity. While investigating resources and identity is useful for archaeological study because of their material correlates, such views of community ultimately fail to acknowledge the dynamic interaction between cultural and environmental forces in shaping and shifting those arrangements over time. This study examines settlement, excavation, and geoarchaeological data from the Palmarejo Valley in northwestern Honduras with the aim of modeling the process of community formation at the intersection of social and natural landscapes in …

Good Girl, Bad Girl: The Role Of Abigail And Jessica In The Jew Of Malta And The Merchant Of Venice, Anna Beskin Mar 2007

Good Girl, Bad Girl: The Role Of Abigail And Jessica In The Jew Of Malta And The Merchant Of Venice, Anna Beskin

USF Tampa Graduate Theses and Dissertations

In The Jew of Malta and The Merchant of Venice, both Christopher Marlowe and William Shakespeare question anti-Semitism, Christian presumption, and socially constructed gender roles. Often compared, the two plays have obvious similarities: both plots center on rich, Jewish protagonists---Barabas in The Jew of Malta and Shylock in The Merchant of Venice---who are vilified and then destroyed by a merciless Gentile society. On the surface, the protagonists' daughters---Abigail in The Jew of Malta and Jessica in The Merchant of Venice---also share many similarities. Both are the young, beautiful daughters of rich and much maligned Jews; both love …

Modulation Of Adult Neural Plasticity By Proteolytic Catabolism Of Lecticans, Joanne Mayer Jan 2007

Modulation Of Adult Neural Plasticity By Proteolytic Catabolism Of Lecticans, Joanne Mayer

USF Tampa Graduate Theses and Dissertations

The extracellular environment of the central nervous system (CNS) through which neuritic processes must traverse during development or after injury is complex, and may vary from stabile conditions to a milieu favorable for neural plasticity and growth. The extracellular space in the CNS accounts for about 20% of brain volume and is composed of aggregating complexes of several different extracellular matrix (ECM) molecules. The ECM supports neural networks and acts as a barrier for neurite extention, depending on the type of molecules involved and the various signals they induce. One mechansim that may produce an environment favoring plasticity is the …

An Experimental Study Of Pro-Dieting And Anti-Dieting Psychoeducational Messages: Effects On Immediate And Short-Term Psychological Functioning And Weight Control Practices In College Women, Megan Roehrig Jan 2007

An Experimental Study Of Pro-Dieting And Anti-Dieting Psychoeducational Messages: Effects On Immediate And Short-Term Psychological Functioning And Weight Control Practices In College Women, Megan Roehrig

USF Tampa Graduate Theses and Dissertations

While dieting is relatively normative in our society, it is controversial within the fields of eating disorders and obesity. Dieting for weight loss has been touted by the obesity prevention field as a solution to the growing obesity epidemic, yet a body of research in the eating disorders field has also implicated it in the etiology and maintenance of eating pathology. Thus, a divergence in approaches toward dieting has emerged, with both prodieting and anti-dieting messages being recommended. Little is known, however, about the impact of these two types of messages on immediate and short-term psychological functioning and weight control …

Hot Flashes In Men With Prostate Cancer: Prevalence, Severity, And Psychosocial Correlates, Erin Winters May 2006

Hot Flashes In Men With Prostate Cancer: Prevalence, Severity, And Psychosocial Correlates, Erin Winters

USF Tampa Graduate Theses and Dissertations

The present study evaluated the prevalence, severity, and psychosocial correlates of hot flashes in men receiving androgen deprivation therapy for prostate cancer. Seventy-two men completed a detailed packet of questionnaires prior to the initiation of treatment and again three-months later. Results indicated that the extent to which hot flashes interfered with patients' daily functioning significantly contributed to changes in depressive symptoms. Changes in fatigue were found to mediate the relationship between hot-flash related interference and depressive symptomatology, suggesting that increases in fatigue were responsible for the concurrent increases in symptoms of depression. The coping strategy of catastrophizing moderated the relationship …
