The Effects Of Homophobia, Legislation, And Local Policies On Heterosexual Pupil Services Professionals' Likelihood Of Incorporating Gay Affirming Behaviors In Their Professional Work With Sexual Minority Youths In Public Schools, Lance Santoro Smith

USF Tampa Graduate Theses and Dissertations

Research suggests that non-judgmental, unbiased counseling (that includes an advocacy component) is effective in addressing the psycho-social needs of sexual minority youths--a population of students considered at-risk (Reynolds & Koski, 1994; Savin-Williams, 1994). The ability to provide such services is impeded if the clinician has not first come to terms with his or her own feelings and attitudes about homosexuality (Pederson, 1988). This study examined the attitudes and anticipated professional behaviors relevant to sexual minority youths of 309 pupil services professionals in the fields of school psychology, school social work, school nursing, and school counseling. Participants from two regions of …

Pediatric sleep problems are among the most common pediatric health issues faced by families today. Sleep problems can have a deleterious impact on children's academics, behaviors, social-emotional development, health, and/or safety. Once sleep problems are identified and treated, many of the associated negative impacts can be ameliorated. The purpose of the current study was to examine prevalence rates of symptoms of sleep disorders in young children, and the relationship between these symptoms and various behavior problems. One hundred and four children, ages 2 to 5 years, attending a pediatric health clinic served as the participants in this study. Data on …

Bathymetric Alterations Due To Urbanization And Their Effects On Residual Salinity, Flow Field And Transport Time For Tampa Bay, Florida, Amanda J. Linville

USF Tampa Graduate Theses and Dissertations

Growth and development over the past one hundred years has resulted in the construction of causeways and navigational channels in Tampa Bay. Urbanization has lead to bathymetric alterations of the bay, and thus has effectively changed the residual salinity, flow fields, and transport time in Tampa Bay. In this study a numerical ocean model of Tampa Bay was first used to simulate the circulation for 2001-2003 using present day bathymetry. Then, an identical simulation was performed using the bathymetry generated from 1879 depth soundings. The residual (30-day time average) circulation fields and salinity, along with transport times was intercompared for …

Ecological Art: Ruth Wallen And Cultural Activism, Susan Birchler

USF Tampa Graduate Theses and Dissertations

Twentieth century modernity has provoked multiple problems ranging from environmental degradation to human rights violations. Globally, diverse communities of people have organized to promote, not just reactive reforms, but a fundamental alteration of the foundational worldview underlying these issues. Radical activists committed their work to promoting an alternative ethos based on egalitarian, democratic, and ecologically-wise concepts. An array of methodologies emerged from these endeavors. More radical political groups focused on cultural tools to engage people in the construction of an alternative worldview. Radical activists utilized two forms of cultural politics: prefigurative politics, the physical presentation of an envisioned future and …

Structure-Function Studies Of Conserved Sequence Motifs Of Cytochrome B5 Reductase:, Louis J. Crowley

USF Tampa Graduate Theses and Dissertations

NADH:Cytochrome b₅ Reductase (cb₅r) catalyzes the two electron reduction of the iron center of the heme cofactor found within cytochrome b₅ (cb₅) utilizing reducing equivalents of the nicotinamide adenine dinucleotide (NADH) coenzyme. Cb₅r is characterized by two domains necessary for proper enzyme function: a flavin-binding domain and a pyridine nucleotide-binding domain. Within these domains are highly conserved "motifs" necessary for the proper binding and orientation of both the NADH coenzyme and the FAD cofactor.

To address the importance of these conserved motifs site-directed mutagenesis was utilized to generate a …

The Association Between Risk Taking And Personality, Gabriella Anic

USF Tampa Graduate Theses and Dissertations

The aim of this study was to examine the association between personality and risk taking in a sample of 461 older adults from the Charlotte County Healthy Aging Study (CCHAS). The personality factors of openness to experience, extraversion, neuroticism, agreeableness and conscientiousness were measured with the NEO Five Factor Inventory. Risk-taking was measured with an 8-item questionnaire and a single-item question that assessed subjects' participation in sensation seeking behaviors. Spearman correlation coefficients, hierarchical linear regression and hierarchical logistic regression were used to assess the association. As consistent with past research, high scores on openness to experience (beta = 0.16, P<.0001) and low scores on neuroticism (β = -0.14, P<.01) and agreeableness (β = -0.16, P<.01) were associated with the total score of the 8-item risk taking questionnaire. The single-item risk question was also associated with openness [OR = 1.09; 95% CI: 1.05-1.13], neuroticism [OR = 0.94; 95% CI: 0.90-0.97] and agreeableness [OR = 0.95; 95% CI: 0.92-0.99]. After stratifying by gender, only openness was still significantly associated with risk-taking. Interaction terms including gender and personality factors were added to the models to test if gender was an effect modifier. Although personality differences existed between men and women, none of the interaction terms were statistically significant.

Growth Factor-Mediated Telomerase Activity In Ovarian Cancer Cells, Yira Bermudez

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is the leading cause of gynecological cancer death in the United States. Even though no single genetic alteration can be attributed to all ovarian cancers, 90% of ovarian tumors express telomerase, a ribonucleoprotein that elongates telomeric (TTAGGG)n repeats de novo. In normal somatic cells, telomerase is absent. In cancer cells, the re-expression of telomerase allows senescence to be bypassed contributing to cellular immortalization, a key step for cellular transformation, making telomerase a potentially important target for therapeutic intervention.

Ovarian cancer cells secrete vascular endothelial growth factor (VEGF) and lysophosphatidic acid (LPA) that feedback through their receptors present …

Novel Polymer-Metal Nanocomposites For Applications In Detection And Sensing, Dayling L. Chaparro

USF Tampa Graduate Theses and Dissertations

Detection of trace elements such as organic contaminants, explosive residues, and metal ions is an intellectually challenging task in science and engineering. It is also a topic of increasing importance due to its impact on society and the environment. Designing molecularly imprinted materials is one of the most promising approaches to explore sensing and detection applications. “Stimuli-sensitive” polymer materials are ideal candidates for these imprinted sensors as they are able to respond to changes in their environment and can be tailored by cross-linking the polymer chains. The responses can be amplified and transduced into measurable signals due to macromolecular properties …

Shakespearean Spin-Offs: Mindless Entertainment Or Conversations With Critics, Amy Anderson

USF Tampa Graduate Theses and Dissertations

Literature is always in a state of evolution. Words change; the way writers write changes. Even actual literary works transform. William Shakespeare manipulated numerous classic works of literature to make extraordinary dramas for both his lifetime and eras since. Much as Shakespeare adapted literature to suit his purposes, writers today are constantly utilizing story lines introduced by the bard over four-hundred years ago in various modern-day mediums. Shakespeare wrote most of his works for the entertainment of the masses; Shakespeare's works are adapted today for both entertainment and academic endeavors. Certainly, a Klingon (Star Trek) version of arguably …

The Effects Of Invasive Cogongrass (Imperata Cylindrica) On The Threatened Gopher Tortoise (Gopherus Polyphemus), Katherine A. Basiotis

USF Tampa Graduate Theses and Dissertations

The gopher tortoise (Gopherus polyphemus) is critical to upland communities and considered a keystone species. A recent threat to gopher tortoise habitat is the invasive cogongrass (Imperata cylindrica), which spreads rapidly, eliminating native vegetation. This study consisted of three experiments to investigate the effects of the cogongrass on a population of gopher tortoises. A feeding experiment revealed that individuals readily ate native vegetation, but would not eat cogongrass. A tracking experiment showed that there was a significantly different mean angle of movement between individuals whose home ranges were outside cogongrass compared to those that overlapped cogongrass, …

Making Sense Of Complex System Failure: The Case Of 9/11, Sandra M. Cooper

USF Tampa Graduate Theses and Dissertations

The National Commission on Terrorist Attacks attributed the September 11 attacks on the U.S. homeland to the terrorists' exploitation of "deep institutional failings." These findings are similar to the conclusions of the Presidential Commission investigating the 1986 Challenger accident and the Columbia Accident Investigative Board (2003). Generally Commissions aim to provide the fullest possible account of events contributing to the catastrophe under investigation and to identify lessons learned, but avoid specifying responsibility and accountability. For this reason, various commission reports have been criticized for being abstract and shallow. These criticisms make a valid point. How commissions make sense of failures …

The Role Of Computer-Mediated Communication In Non-Native Speakers’ Acquisition Of Academic Literacy, Rui Cheng

USF Tampa Graduate Theses and Dissertations

Research shows that academic literacy is discipline specific. Students have to learning the ways of communication in order to gain access to the discourse community of the selected discipline through understanding and performing required genres and learning necessary disciplinary knowledge. Scaffolding is important in the process to help students internalize the disciplinary knowledge and improve students' performance on academic papers. Computer-mediated communication (CMC) provides good chances of scaffolding and mediation especially for non-native graduate students who may have lost many opportunities of class participation due to their limited language proficiency or other cultural issues.

In this dissertation, the researcher investigated …

An Unexplored Realm In The Heartland Of The Southern Gulf Olmec: Investigations At El Marquesillo, Veracruz, Mexico, Travis F. Doering

USF Tampa Graduate Theses and Dissertations

This dissertation examines El Marquesillo, a settlement in an archaeologically unexplored region of the Southern Gulf Lowlands of Veracruz, Mexico. Evidence suggests the site has been consistently occupied from the Early Formative period (c. 1500 BC) to the present. Thus, this investigation presents an opportunity to re-examine the sociopolitical continuum encompassing the Olmec cultural phenomenon (c. 1150-300 BC), the emergence of which has been used repeatedly as an example of incipient social complexity.

Theorists have portrayed the development of sociopolitical complexity as a mosaic process in which environmental, social, political, economic, ideological, and demographic variables act independently or in combination …

Internalized Racism As A Moderator For Stereotype Threat: Effects On Self-Handicapping, Performance, And Cardiovascular Responses In Black Individuals, Nicole Ellis Jagusztyn

USF Tampa Graduate Theses and Dissertations

The purpose of the present study was to explore the relationship between internalized racism, stereotype threat, self-handicapping, test performance, and cardiovascular responses in Black individuals. Stereotype threat, or apprehension about confirming a negative stereotype, has been shown to lead to self-handicapping, poor academic performance, as well as increased cardiovascular reactivity. Internalized racism, or the acceptance of negative stereotypes about one's group, is a factor that may moderate these relationships. One-hundred nine (84% female, 16% male) Black undergraduates participated in a laboratory study. Half of the participants were put in a stereotype-threatened condition and the other half were in a neutral …

Queer Identity? Discussing Identity And Appearance In An On-Line “Genderqueer” Community, Sharla N. Alegria

USF Tampa Graduate Theses and Dissertations

The relatively new field of Queer Theory creates ways of thinking about people living without binary gender, but does not provide for a research model with which to give context to the material struggles of such people. Through the use of Internet discussion groups, the current research project attempts to examine the challenges that people who identify with the concept "genderqueer" describe facing as they fashion selves in social interactions; a process which inevitably requires consumer goods that typically only allow for heteronormative binary gender. Findings suggest that there are similarities in how respondents came to identify with "genderqueer," but …

Archival data were retrieved by chart review for this study and was used to answer the following questions: 1) What is the prevalence of language disorders in children referred for a psychiatric evaluation? 2) Do behavioral symptoms vary among children with and without a language disorder? and 3) What is the initial area of concern identified by the parents of children with language and behavior disorders? …

Using Frequency Analysis To Determine Wetland Hydroperiod, Lisa D. Foster

USF Tampa Graduate Theses and Dissertations

Wetlands are nominally characterized by, vegetation, presence of saturated soils and/or period and depth of standing water (inundation). Wetland hydroperiod, traditionally defined by the period or duration of inundation, is considered to control the ecological function and resultant plant community. This study seeks to redefine "hydroperiod" to incorporate both surface and subsurface water-level fluctuations, to identify predominant hydroperiod of different wetland types, and to find the range of the water-level fluctuations during the predominant hydroperiod durations. The motivation being that wetland ecological condition is controlled not just by the period of inundation but also by the proximity and depth to …

Assessing The Health Of Coral Reef Ecosystems In The Florida Keys At Community, Individual, And Cellular Scales, Elizabeth Fisher

USF Tampa Graduate Theses and Dissertations

Coral reefs are threatened in Florida and worldwide. Successful resource management requires rapid identification of anthropogenic sources of stress before they affect the reef community. I tested a multi-scale approach for assessing reef condition at seven reefs within the Florida Keys National Marine Sanctuary and Biscayne National Park between 2001 and 2003. I examined multiple environmental parameters to identify potential sources of stress. I utilized the Atlantic and Gulf Rapid Reef Assessment Biotic Reef Index to assess benthic community structure and an indicator species of Foraminifera (Amphistegina gibbosa) to determine if environmental conditions were suitable for calcareous organisms …

Falling In Love As A Heuristic For Mate Choice Decisions, Monica D. Burke

USF Tampa Graduate Theses and Dissertations

Selecting a mate is one of the most important and complex decisions that we make in our lives. Research on human decision making has found that we often use simple rules of thumb or heuristics to facilitate complex decision-making tasks (e.g., Gigerenzer & Todd, 1999; Kahneman & Tversky, 1972, 1973; Tversky & Kahneman, 1974, 1983). Recent research has focused on the use of affect or emotion as heuristics that have a strong influence on a variety of decision making contexts (Damasio, 1994; Finucane, Peters, & Slovic, 2003; Loewenstein, Weber, Hsee, & Welch, 2001; Mellers, 2000). The emotion we most closely …
