Exploring Instructional Strategies And Learning Goals In Undergraduate Leadership Education, Daniel Jenkins

USF Tampa Graduate Theses and Dissertations

Leadership education has been integral to the undergraduate curriculum since the early 1990's. Today, more than 1,000 colleges and universities in the United States offer undergraduate courses in leadership studies and many offer academic credit in the form of a bachelor's degree, academic minor, or certificate. Yet, little is known about those who teach leadership studies courses to undergraduates, the instructional strategies they employ, or the learning goals they set. The purpose of this study was to identify the instructional strategies that are most frequently used by instructors when they teach academic credit-bearing undergraduate leadership studies courses, identify signature pedagogies …

Biodegradation Of Bisphenol-A And 17b-Estradiol In Soil Mesocosms Under Alternating Aerobic/Anoxic/Anaerobic Conditions, Won-Seok Kim

USF Tampa Graduate Theses and Dissertations

Soil-aquifer treatment (SAT) has been proposed as a method for reusing treated municipal wastewater. SAT is characterized by alternating cycles of aerobic and anaerobic conditions in the subsurface, in response to alternating cycles of flooding and drainage of a surface impoundment. It is not yet known how these alternating redox conditions affect the removal of potentially harmful endocrine-disrupting compounds (EDCs) from treated effluent.

The overall objective of my doctoral research is to determine the fate of EDCs in alternating aerobic/anoxic/anaerobic conditions under simulated SAT conditions. To assess the fate of EDCs in simulated SAT conditions, I first had to develop …

Talking With Als Patients: An Exploratory Study Of Patient Attitudes Toward Mass Messages About Als, Kamden Kuhn

USF Tampa Graduate Theses and Dissertations

This study examines the attitudes and opinions of ALS patients toward mass messages about their condition. Six focus groups of ALS patient support groups viewed and responded to public relations messages, charity advertisements, and a news story. Results suggest that mass messages remind participants of the need for public ALS awareness. Participants also said they shared in the narratives and identify closely with the characters in the messages they viewed, and participants expressed concern with disease depictions. These concerns included a tension between positive and realistic portrayals, identification of message inaccuracies, and a desire for more specific disease information. The …

USF Tampa Graduate Theses and Dissertations

This study examines the coverage of women’s athletics at USF provided through photographic representations on the university’s Athletics Internet home web page during the 2009–2010 academic year. Findings from this census of five areas that comprise the USF Athletics Internet home web page revealed that, consistent with recent research on coverage of female athletes and women’s athletics on university web pages, women, compared to men, were underrepresented in the majority of the five areas of the home page analyzed. The difference in the number of overall total photographs of women and men was not that large—48% and 52%, respectively, not …

That Is Bad! This Is Good: Morality As Constructed By Viewers Of Television Reality Programs, Joseph Charles Losasso

USF Tampa Graduate Theses and Dissertations

Reality shows that feature people going about their presumed daily lives are not base entertainment. Internet message boards about reality programs are sites where moral work happens. Viewers write about the appearance and actions of show characters and construct moral lessons. Through naturally occurring data produced by fans of these shows, I find that viewers generally express a traditional heteronormative morality around class and gender through stating moral lessons, explaining what is wrong with the characters, or through ridicule and praise.

Role Of Cmc-Embedded Webquests In Enhancement Of Online Students' Knowledge And Understanding Of German Culture - A Case Study, Radhika Lothe

USF Tampa Graduate Theses and Dissertations

Existing approaches to teaching `culture' in the realm of Distance foreign language (FL) instruction and gaps within; under-researched Computer Assisted Language Learning (CALL) tool of webquests; and Mediation in Sociocultural Theory (SCT) have all led to the following case study. This study was guided by the constructs of `culture' in FL instruction, Sociocultural Theory, and literature in CALL and Computer-Mediated Communication (CMC).

This study examines how CMC-embedded webquests (asynchronous and synchronous CMC components built into webquests) developed online students' knowledge and understanding of German culture. Additionally, this study examines what mediating strategies (Lidz, 2002) were used by the online students …

The Return Of The 1950s Nuclear Family In Films Of The 1980s, Chris Steve Maltezos

USF Tampa Graduate Theses and Dissertations

In the 1980s the cinematic nuclear family flourished again after the self-explorative 1960s and turbulent 1970s. This thesis explores the portrayal of the idealized American family in film between the 1950s and 1980s. The 1955 film Rebel Without a Cause reflects the 1950s cinematic family model. My investigation includes the role of the father figure and the bonds in intergenerational relationships. During the early 1980s, films such Ordinary People and ET: The Extraterrestrial reflect the need to reevaluate the 1950s ideal nuclear family. My examination of these films continues to include the importance of the father figure and bonds between …

A Swmm-5 Model Of A Denitrifying Bioretention System To Estimate Nitrogen Removal From Stormwater Runoff, Michelle D. Masi

USF Tampa Graduate Theses and Dissertations

This research estimates nitrogen removal from stormwater runoff using a denitrifying bioretention system using the USEPA Storm Water Management Model Version 5 (SWMM-5). SWMM-5 has been used to help planners make better decisions since its development in 1971. A conventional bioretention system is a type of Low Impact Development (LID) technology, which designed without a media layer specifically for achieving nitrogen removal. More recently studies have showed that high TN removal efficiencies are possible when incorporating a denitrification media layer. These systems are known as denitrifying bioretention systems, or alternative bioretention systems. LID projects are currently being designed and developed …

Design And Analysis Of An Innovative Semi-Flexible Hybrid Personal-Body-Armor System, Daniel Jeffrey Miller

USF Tampa Graduate Theses and Dissertations

Current military-grade rifle body armor technology uses hard ballistic plates positioned on top of flexible materials, such as woven Kevlar® to stop projectiles and absorb the energy of the impact. However, absorbing the impact energy and stopping a rifle projectile comes at a cost to the wearer - mobility. In this thesis, a new concept for personal body armor is proposed - a semi-flexible hybrid body armor. This hybrid armor is comprised of two components that work as a system to effectively balance the flexibility offered by a soft fabric based armor with the protection level of hard plated armor. …

Cold War Playboys: Models Of Masculinity In The Literature Of Playboy, Taylor Joy Mitchell

USF Tampa Graduate Theses and Dissertations

"Cold War Playboys: Models of Masculinity in the Literature of Playboy" emphasizes the literary voices that emerged in response to the Cold War's redefinitions of space and sexuality and, thus, adds to the growing national discourse of Cold War literary and masculinity studies. I argue that the literature Playboy includes has always been a necessary feature to creating its masculinity model; however, that very literature often destabilizes the magazine's grand narrative because it presents readers with alternative models of masculinity. To make that argument, I presume five things: 1) masculinity, like femininity, is a construct; 2) the mid-century masculinity …

Translation And Adaptation Of The Center For Epidemiologic Studies-Depression (Ces-D) Scale Into Tigrigna Language For Tigrigna Speaking Eritrean Immigrants In The United States, Mulubrhan Fisseha Mogos

USF Tampa Graduate Theses and Dissertations

Depression is one of the oldest known mental health conditions. It is acknowledged to be a global health problem that affects people from any culture or ethnic group. The prevalence of depression widely varied across countries and cultures. The cross-cultural relevance of the concept of depression, its screening or diagnosis, and cultural equivalence of items used to measure symptoms of depression has been area of research interest. Differences in prevalence rates in depression have been suggested as being due to research artifacts, such as use of instrument developed for one culture to another culture. With the current trend of globalization …

Investigation Of The Optimal Dissolved Co2 Concentration And Ph Combination For The Growth Of Nitrifying Bacteria, Raymond Anthony Morris

USF Tampa Graduate Theses and Dissertations

Ammonium (NH₄⁺) is a biological nutrient that is transformed in a wastewater treatment plant (WWTP) in a process called activated sludge. This is accomplished in an aerobic environment using microorganisms and inorganic carbon that convert the ammonium to nitrate (NO₃^-). This process is termed nitrification. Removal of ammonium is necessary due to its oxygen demand and toxicity to the environment.

Nitrification is considered a slow process due to the slow growth rate of the nitrifying bacteria. Ammonia oxidizing bacteria (AOB) first covert the ammonium (NH₄⁺) to nitrite (NO₂^-) …

The Threat To Democracy In Brazil's Public Sphere, Daniel Nettuno

USF Tampa Graduate Theses and Dissertations

This thesis looks at the nature of violence with its endemic, and increasingly epidemic presence in Brazil. I analyze the structure of the justice system, police force, and the many governmental security programs in order to better explain why Brazil is so violent and its government has been unable to control this violence. Living under violent conditions, Brazil has become a society where the efficient functioning of the public sphere has been undermined. This public space, shared by citizens, is what many academics believe to be a critical component of a robust and functioning democracy. In Brazil, it is shown, …

Environmental Health In The Latin American And Caribbean Region: Use Of Water Storage Containers, Water Quality, And Community Perception, Erlande Omisca

USF Tampa Graduate Theses and Dissertations

Water quality and availability are important issues in many developing countries where portions of populations still lack access to potable water. Throughout the English-speaking Caribbean and parts of Latin America, households and businesses invest in water supply systems even when they are connected to and pay for water services from a private or state owned provider. Inconsistent supplies of water from the water companies have led many people to invest in storage tanks which, if operated correctly, can provide water throughout the day even when the supply from the main is low or zero. While these individual systems help to …

Catalytic Hydrodehalogenation And Hydrogenation Of Halogenated Aromatic Organic Contaminants For Application To Soil Remediation, Claire J. Osborn

USF Tampa Graduate Theses and Dissertations

The objective of this research was to aid in the development of a new method for removing and destroying soil contaminants. In particular, 1,2,4,5-tetrachlorobenzene (TeCB) was selected for this research. Hydrodehalogenation (HDH) was paired with hydrogenation for remedially destroying TeCB without generating a secondary waste stream in a single batch reactor. Palladium- and rhodium-catalyzed HDH and hydrogenation were applied in a batch reactor at room temperature and moderate hydrogen pressure. Cyclohexane was formed as an end product with benzene as an intermediate reactant.

An analytical method was developed to measure TeCB, benzene, and cyclohexane in a solution of water and …

Crystal Engineering Of Molecular And Ionic Cocrystals, Tien Teng Ong

USF Tampa Graduate Theses and Dissertations

Solubility enhancement of poorly-soluble active pharmaceutical ingredients (APIs) remains a scientific challenge and poses a practical issue in the pharmaceutical industry. The emergence of pharmaceutical cocrystals has contributed another dimension to the diversity of crystal forms available at the disposal of the pharmaceutical scientist. That pharmaceutical cocrystals are amenable to the design principles of crystal engineering means that the number of crystal forms offered by pharmaceutical cocrystals is potentially greater than the combined numbers of polymorphs, salts, solvates and hydrates for an API. The current spotlight and early-onset dissolution profile ("spring-and-parachute" effect) exhibited by certain pharmaceutical cocrystals draw attention to …

Sol-Gel Resorcinarene Sorbent For Capillary Microextraction Coupled To Gas Chromatography, Abdullah Awadh Alhendal

USF Tampa Graduate Theses and Dissertations

For the first time, octahydroxyl methylresorcinarene with four hexyl groups on the lower rim was utilized in the in-situ preparation of a silica-based sol-gel organicinorganic hybrid coating for sample preconcentration by capillary microextraction (CME). Tetraethoxysilane (TEOS) was chosen as a sol-gel precursor to create a crosslinked sol-gel network via acid-catalyzed hydrolytic polycondensation reactions. Sol-gel chemistry helped in the in situ preparation of resorcinarene-containing extraction phase in the form of a surface coating. It also provided an effective means to chemically bind the coating to the inner surface of fused silica capillary via condensation of the hydroxyl groups in the sol-gel …

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

USF Tampa Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil …

_Alien_ Thoughts: Spectatorial Pleasure And Mind Reading In Ridley Scott's Horror Film, Cecilia Madeline Bolich

USF Tampa Graduate Theses and Dissertations

Pleasure experienced in an unpleasant film genre, like horror, has prompted numerous discussions in film studies. Noted scholars like Carol J. Clover and Noël Carroll have rationalized spectatorial enjoyment of a genre that capitalizes on human anxieties and complicates cultural categories. Clover admits that horror initially satisfies sadistic tendencies in young male viewers but then pushes them to cross gender lines and identify with the strong female heroine who defeats the film's threat. Carroll provides a basic explanation, citing spectators' cognitive curiosity as the source of pleasure. Both scholars are right to consider emotional, psychological, and cognitive experiences felt by …

A Focus Group Study Of Baby Boomers' Processing And Interpretations Of Fear Appeals In Health Care Reform Political Advertising, Allyson Dawn Calandro

USF Tampa Graduate Theses and Dissertations

This qualitative research study describes the processing and interpretations of "Baby Boomers" in response to fear appeals from two health care reform political advertisements. Research suggests that scholars continue to disagree on the audience's interpretations of fear appeals, based on studies comparing different levels of fear, emotions, and interpretations by specific members of the population. However, little is known about how "Baby Boomers" interpret fear used in health care reform advertising. The method included six focus groups. Thematic analysis revealed five key themes: "Baby Boomers'" processing produced a range of emotions, they demand more facts, the fear expressed was fear …

Sexually Explicit, Socially Empowered: Sexual Liberation And Feminist Discourse In 1960s Playboy And Cosmopolitan, Lina Salete Chaves

USF Tampa Graduate Theses and Dissertations

In this thesis, I provide an analysis of 1960s American popular culture by examining Playboy, "The Playboy Philosophy," Cosmopolitan, and Sex and the Single Girl. These cultural artifacts furthered the feminist movement by challenging gender structures and sexuality. I discuss how these publications focused on the advancement of the individual through careerism, consumerism and sexuality. These publications assisted in challenging and breaking down various aspects of gender and sexual boundaries and assisted in reworking social limitations that kept women from advancing themselves outside of the pre-set gender roles of domesticity. Regardless of the traditional feminist critique of …

Analysis Of Ahr Expression And Stability In A Recombinant Yeast Model System, Sarah Elizabeth Cuccinello

USF Tampa Graduate Theses and Dissertations

The aryl hydrocarbon receptor (Ahr) and the aryl hydrocarbon receptor nuclear translocator (Arnt) are well characterized bHLH-PAS transcription factors shown to regulate expression of xenobiotic metabolism genes. Extensive study has shown that upon treatment with certain aromatic hydrocarbons, mammalian cells rapidly activate the Ahr signaling pathway in order to stimulate gene expression and attempt to metabolize the xenobiotic compounds. It has been shown that after DNA-binding, the Ahr but not the Arnt protein, is quickly eliminated from the nuclear compartment thereby attenuating the dose of gene regulation administered by the Ahr*Arnt transcription factor complex. Previous studies have implicated involvement of …

More Than "Modern Day Slavery": Stakeholder Perspectives And Policy On Human Trafficking In Florida, Nathaniel Dickey

USF Tampa Graduate Theses and Dissertations

In recent years, Florida has acquired a reputation as fertile ground for human trafficking. On the heels of state and federal anti-human trafficking legislation, a host of organizations have risen to provide a range of services. In this thesis, I discuss findings from 26 interviews conducted with law enforcement, service providers, legal representatives and trafficked persons to contextualize the variability in the way anti-trafficking work is conceptualized by stakeholders across the state. Additionally, I explore how conflicting organizational policies on the local, state, and federal levels impact stakeholder collaboration and complicate trafficked persons' attempts to navigate already complex processes of …
