Aggression And Its Consequences In Nursing: A More Complete Story By Adding Its Social Context, Liu-Qin Yang

USF Tampa Graduate Theses and Dissertations

Using a 471-case nursing sample, the current study examined the direct and indirect relationships between workplace aggression (including physical and psychological) against nurses and their health and safety consequences. Specifically, physical and psychological aggression nurses experienced were related to their job dissatisfaction, turnover intention, physical symptoms, injuries and exposure to contagious disease directly and/or indirectly through their emotional strain (irritation, anxiety, and depression). In addition, my findings demonstrated that stronger violence prevention climate (i.e., good prevention practices/response and low pressure for unsafe practices) was related to less frequent violence and psychological aggression incidents nurses experienced. Also, my results indicated significant …

Developing Feminist Activist Pedagogy: A Case Study Approach In The Women's Studies Department At The University Of South Florida, Stacy Tessier

USF Tampa Graduate Theses and Dissertations

In this thesis, I examine the relationship between activism and the two introductory-level Women's Studies classes, Introduction to Women's Studies and Issues in Feminism, and the social justice mission of the Women's Studies department. These two classes are the pillars for the program and are often the first classes that draw students into the program. I propose that the Women's Studies department does promote social justice through the curriculum and there are ways that the department could do more to facilitate activism in the classroom and beyond the classroom.

The Women's Studies department at the University of South Florida is …

Risk Communication: An Analysis Of Message Source And Function In Hurricane Mitigation/Preparedness Communication, Andrew M. Gallo

USF Tampa Graduate Theses and Dissertations

In September 2008, the National Weather Service (NWS) predicted that Hurricane Ike would make landfall on Galveston Island as a strong category three storm. This led the NWS to release a statement of 'certain death' if people did not adhere to the emergency evacuation messages. Millions of people fled the Texas coast. Using Hazleton and Long's (1993) taxonomy of public relations strategies, experimental methods were conducted with various evacuation messages to test emergency communication. Grunig's (1997) situational theory of publics was used to determine strategy influence. Problem recognition, constraint recognition, and level of involvement were tested. In addition, tests were …

Beyond Academic Reputation: Factors That Influence The College Of First Choice For High Achieving Students, Holly J. Schoenherr

USF Tampa Graduate Theses and Dissertations

Studies that have investigated college choice factors for high-achieving students repeatedly cite academic reputation as one of the top indicators of choice but have not indicated why some high-achieving students choose to attend universities with a less prestigious reputation than the more highly prestigious options available to them. The purpose of this study was to examine whether differences exist between traditional-aged high achieving students who choose to attend higher-tiered universities and their peers who choose to attend lower-tiered universities.

Independent variables were selected based upon Hossler and Gallagher's (1987) three-stage model and previous research findings in the literature and grouped …

“I Stand For Sovereignty”: Reading Portia In Shakespeare’S The Merchant Of Venice, Deborah Van Pelt

USF Tampa Graduate Theses and Dissertations

Portia serves as a complex and often underestimated character in William Shakespeare's controversial comedy The Merchant of Venice. Using the critical methodologies of New Historicism and feminism, this thesis explores Portia's representation of Elizabeth Tudor, Queen of England from 1558 to 1603. Striking similarities exist between character and Queen, including physical description, suitors, marriage issues, and rhetoric. In addition, the tripartite marriage at the play's conclusion among Portia, Bassanio, and Antonio represents the relationship Elizabeth Tudor formed between her merchant class and her aristocracy. Shylock serves as a representation of a generic or perhaps Catholic threat to England during …

With this thesis, I will utilize both feminist and queer theory to highlight the gendered and bodily tactics used by the women of the 1970s/1980s Provisional Irish Republican Army. I will explore how women can both manipulate gender and use their bodies as a response to gender, ethnic, class, and colonial power relations and conflict discourses, the limitations of these approaches, and how these actions can work to reconfigure political movements, local cultures, and create a space for social change and a future beyond conflict which includes women. My methods will include a feminist content analysis of interviews, written records, …

Modulation Of Asic1a Function By Sigma-1 Receptors: Physiological And Pathophysiological Implications, Yelenis Herrera

USF Tampa Graduate Theses and Dissertations

Acid-sensing ion channels (ASIC) are a class of ligand gated plasma membrane ion channels that are activated by low extracellular pH. During ischemia, ASIC1a are activated and contribute to the demise of neurons. Pharmacological block of ASIC1a provides neuroprotection at delayed time points. However, no endogenous receptors have been implicated in the modulation of ASIC1a activity. The hypothesis presented is that sigma receptor activation inhibits ASIC1a function and ASIC1a-induced [Ca²?]i elevations during acidosis and ischemia, which may be a mechanism by which sigma ligands provide neuroprotection following stroke. This hypothesis is based on the following observations: First, sigma receptors regulate …

The Daily Show: Journalism’S Jester, Mark R. Mccarthy

USF Tampa Graduate Theses and Dissertations

The social meaning of television news has been under transformation since the successes of cable news in the final years of the previous century. In their attempts to preserve viewership and to remain relevant, traditional broadcast news outlets increasingly emulate the conventions of cable news. Instead of retaining audiences, the result has been declining news content and a continued loss of viewers. Amid these industry transformations, the concept of “journalist” continues to undergo change. This evolution of the news allows for a decidedly unique response to news programming in The Daily Show With Jon Stewart. Though advertised as a half-hour …

Correlates Of Body Depilation In Men, Michael Boroughs

USF Tampa Graduate Theses and Dissertations

Body depilation is a relatively new area of research inquiry. Although women in many industrialized cultures have engaged in body depilation for some time, this behavior has been documented only recently in men. While originally thought to be the practice of just a small percentage of men, recent studies suggest that more men engage in body depilation than had been previously hypothesized (Boroughs & Thompson, 2002; Boroughs, Cafri, & Thompson, 2005; Martins, Tiggemann, & Churchett, 2008; Tiggemann, Martins, & Churchett, 2008). Nevertheless, this area of research is understudied and the relationship between body depilation and men's overall body image is …

A Quasi Yagi Antenna With End Fired Radiation Over A Metal Ground, Sergio E. Melais

USF Tampa Graduate Theses and Dissertations

This dissertation presents a detailed investigation on the development of a quasi Yagi antenna with end fire radiation at 2.4 GHz (ISM band) over a metal reflector. Realization of an end fire radiator on top of a metal ground is very difficult because the reflected waves and image currents from the ground degrade the frequency bandwidth and steer the radiation pattern in the broadside direction. This destructive interference is reduced in this research through two quasi Yagi-ground configurations. The first arrangement utilizes a substrate of suitable thickness (7.5mm-0.19 ?g) to displace the ground away from the antenna. The second design …

Sympathy For The Devil: A Character Analysis Of Gibreel Farishta In Salman Rushdie’S The Satanic Verses, Catherine Mary Lafuente

USF Tampa Graduate Theses and Dissertations

Salman Rushdie's The Satanic Verses created a major controversy when published in 1988, much like the controversy that Nikos Kazantzakis's novel The Last Temptation of Christ caused in 1951. Kazantzakis's work upset many Christians due to the controversial characterization of Jesus, who in the novel engages in sexual activities and other behaviors that many Christians find offensive. The Satanic Verses caused a similar uproar in the Umma, or Muslim community, resulting in book burnings, death threats, and even a murder. Most of the controversy focused on some the problematic characterizations of the Prophet Muhammad and his wives, such as using …
