These teachers are encouraged to serve as mentors to novice teachers and veteran teachers in candidacy for National Board Certification. This study identified and compared the career and psychosocial mentoring functions that NBC teacher mentors and non-NBC teacher mentors perceived they provided to their protégés at the elementary grade levels. National Board-certified protégés’ perceptions of having the functions provided were compared with those of their teacher mentors and with the protégés of non-NBC teacher mentors.

The research was conducted in a large urban …

The Sertoli Cell-Spermatid Junctional Complex: A Potential Avenue For Male Contraception, Katja Margrit Wolski

USF Tampa Graduate Theses and Dissertations

The Sertoli cell ectoplasmic specialization is a specialized domain of the calcium-dependent Sertoli-spermatid adherens junction. Structurally abnormal or absent Sertoli ectoplasmic specializations are associated with spermatid sloughing and subsequent oligospermia in conditions associated with reduced fertility potential, although the junctional strength between these cells is not known. Adjudin is a potential male contraceptive agent thought to interrupt testicular binding dynamics of adherens junctions, resulting in controlled spermatid sloughing.

It was hypothesized that the mechanism of action of Adjudin, pertinent to its putative contraceptive effect, is the disruption of the Sertoli cell-spermatid junction. This was tested in vitro using primary isolates …

The Relationship Between Sleep, Behavior, And Pre-Academic Skills In Pre-Kindergarteners, Rachel B. Witte

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine prevalence rates of several sleep disorders symptoms in young children, and the relationship between symptoms of pediatric sleep disorders and other childhood problems. Eighty-six children aged 3 to 5 years were studied through parent report and academic assessment. Children rated as high risk for having a sleep disorder displayed more externalizing and internalizing problems, less developed social skills, and lower scores on a measure of pre-academic skills, as compared to children whose sleep was rated in the normal range. It was found that 33% of children were at high risk for having …

Measuring Social Stressors In Organizations: The Development Of The Interpersonal Conflict In Organizations Scale (Icos), Valentina Bruk Lee

USF Tampa Graduate Theses and Dissertations

Interpersonal conflict in organizations has been recognized as a leading social stressor across occupations with detrimental effects on employee well-being and organizational outcomes. However, reliable and valid measures of conflict are scarce and even the most widely used scales are limited by weaknesses in construct definition. In order to address the need for an improved measurement tool, the 63-item Interpersonal Conflict in Organizations Scale (ICOS) was developed. The ICOS was based on a comprehensive conceptualization of conflict that defines the construct on the basis of three definitional components: disagreement, interference, and negative emotion (Barki & Hartwick, 2004). In addition, the …

Uncontrollable And Unpredictable Stress With A Reminder Experience Induces Long-Lasting Effects On Physiology And Behavior: A Novel Approach To Modeling Post-Traumatic Stress Disorder In Rats, Phillip R. Zoladz

USF Tampa Graduate Theses and Dissertations

People who endure horrific, life-threatening experiences are at risk for developing post-traumatic stress disorder (PTSD). However, only about 25% of all individuals who experience trauma develop PTSD. Recent research indicates that the presence of certain physiological conditions, such as reduced cortisol and parasympathetic inhibition, during trauma may increase one's susceptibility to developing PTSD. Thus, I attempted to develop a novel animal model of PTSD and test the hypothesis that reduced adrenal and parasympathetic activity during stress would exacerbate its long-term effects on behavior.

In Experiment One, adult male rats were exposed to two stress sessions, each involving one hour of …

Assessment Of Occupational Heat Strain, Margaret Wan

USF Tampa Graduate Theses and Dissertations

Assessment of heat strain considers an individual’s tolerance and indicates the risk and physiological cost of working in hot environments. This study evaluated the discrimination ability of metrics of heat strain. The null hypotheses were that (1) the metrics individually could not discriminate between acceptable and unacceptable heat strain, (2) there were no significant differences among these metrics, and (3) there were no significant differences in the applicability of the metrics due to clothing or heat stress level.

The experimental design was a case crossover. Clothing and heat stress level were potential confounders. Two clothing ensembles were work clothes and …

USF Tampa Graduate Theses and Dissertations

People in low socioeconomic status groups are at increased risk for diabetes mellitus, a group of diseases associated with high levels of blood glucose. High rates of depression have been found in people with diabetes. The study examined the relationship between stress, depression, and glycemic control in low-income type 2 diabetes patients. Participants were recruited at two community health centers that provide free medical care. The following hypotheses were examined: (1) experiencing stressful life events is positively correlated with blood glucose level; (2) negative stressful events have a greater association with glucose level than positive stressful events; (3) depression mediates …

A Mechanized Horseback Riding Simulator As An Aid To Physical Therapy, Jennifer Lott

USF Tampa Graduate Theses and Dissertations

Equine-assisted therapy is a nontraditional form of physical therapy that involves riding horses as a form of rehabilitation. Limited access to these riding programs justifies a need to develop a horseback riding simulator capable of simulating the gaits, bend, and collection of the horse. Research involving the development of horseback riding simulators is limited, but the available research does show promising results in the ability to aid in physical therapy.

A two-dimensional model and simulation was developed using MATLAB. Using the results from the simulation, a horseback riding simulator was designed, fabricated and tested. The physical simulator was capable of …

The Reaction To Economic Globalization In Latin America: A Case Study Of Argentina, Lisa A. Warner

USF Tampa Graduate Theses and Dissertations

Since Washington Consensus policies became predominant in the 1980s, two sides of the economic globalization debate have developed: advocates claim that trade liberalization, deregulation, privatization and reduced state spending increase growth and therefore reduce poverty, while critics claim that levels of poverty and income disparity have worsened at the same time that social welfare and education programs have suffered budget cuts. Over the past decade, as many Latin Americans have failed to see promised results to alleviate poverty stemming from the "lost decade" of the 1980s (and beyond), they have elected "leftist" presidents that campaigned on anti-economic globalization (or anti-neoliberal) …

Mining Medical Data In A Clinical Environment, Tim V. Ivanovskiy

USF Tampa Graduate Theses and Dissertations

The availability of new treatments for a disease depends on the success of clinical trials. In order for a clinical trial to be successful and approved, medical researchers must first recruit patients with a specific set of conditions in order to test the effectiveness of the proposed treatment. In the past, the accrual process was tedious and time-consuming. Since accruals rely heavily on the ability of physicians and their staff to be familiar with the protocol eligibility criteria, candidates tend to be missed. This can result and has resulted in unsuccessful trials.A recent project at the University of South Florida …

The Role Of Organizational Culture In The Delivery Of Humanitarian Assistance And Inter-Organizational Collaboration, Jamie Antoinette Wilke Corvin

USF Tampa Graduate Theses and Dissertations

The international community has seen a dramatic increase in the complexity of aid operations, with increasing numbers of donors participating in humanitarian aid endeavors. Therefore, it is essential to determine factors that contribute to successful aid delivery. In an effort to guide more effective and efficient aid operations, this study investigated organizational culture in three distinct types of humanitarian organizations: (a) the U.S. military, (b) the International Federation of the Red Cross, and (c) a sampling of local and indigenous non-governmental organizations. Being a relatively unexplored area, this study took an exploratory approach, utilizing qualitative methods to analyze humanitarian aid …

Use Of Box-Pcr Subtyping Of Escherichia Coli And Enterococcus Spp. To Determine The Source Of Microbial Contamination At A Florida Beach, Miriam J. Brownell

USF Tampa Graduate Theses and Dissertations

Siesta Key Beach, located on the Gulf Coast of Florida, is frequently mentioned among the top ten beaches in the US. In summer 2004, high levels of indicator bacteria caused health warnings to be posted, and a storm drainage system was implicated as a possible source of microbial contamination. A study was initiated to determine whether indicator bacteria that persisted in the stormwater system could contribute to high microbial loads in receiving waters. Two sampling events, one within 48 hours of a rain event and the other during dry conditions, were conducted. Water and sediment samples were taken at various …

Measuring Social Competence In Preschool-Aged Children Through The Examination Of Play Behaviors, Eun-Yeop Lee

USF Tampa Graduate Theses and Dissertations

For young children, a primary component of social competence is establishing effective interactions with peers during play. To inform the development of practices that promote this competency starting in early childhood, quality assessment measures are needed. These instruments must have the capacity to establish linkages between the home and school as well as utilizing multiple informants. A promising early childhood assessment measure is the Penn Interactive Peer Play Scale (PIPPS), which is a rating scale created with parent and teacher versions. Previous research has established its validity for preschoolers from among various populations.

The purpose of this study was to …

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 …

Understanding Eating Boundaries: A Study Of Vegetarian Identities, Susan Kremmel

USF Tampa Graduate Theses and Dissertations

My research uses participants' understandings to look at how people define and use the identities and categories of "vegetarian" and "meat-eater." My research examines what it means to be vegetarian, how ideals and moral hierarchies are understood, and how issues of identity importance, social support, and boundary work are components of vegetarian identity construction processes. My research highlights the unmarked character of the meat-eating identity and investigates the variations and complexities of eating behaviors and identities. Learning more about how both vegetarians and meat-eaters construct vegetarian identities contributes to our understanding of identities and how, despite ambiguities, people experience identities. …

An Investigation Into The Antifungal Activities Of N-Thiolated Beta- Lactams Against Selected Candida Species, Marci Culbreath

USF Tampa Graduate Theses and Dissertations

β-lactam antibiotics have long been a reliable course of treatment for bacterial infections. However, with recent increases in resistance and rising populations of immunocompromised patients new β-lactams have been synthesized and tested. The Turos laboratory has recently discovered novel β-lactams that have a mode of action distinct from penicillin and other β-lactam antibiotics as cell lysis is not observed. In the current investigations, these compounds are shown to also have antifungal properties. The rising incidence and prevalence of invasive fungal infections has become an increasing concern. The most common fungal pathogens involved in these infections are species in the genus …

Carbon dioxide is a natural refrigerant that has been considered for certain refrigeration and air conditioning applications. The coefficient of performance (COP) of carbon dioxide cycles is low compared to classical vapor compression cycles. The aim of this portion of the thesis is to present a thermodynamic analysis of carbon dioxide cycles in order to evaluate the potential performance of a refrigeration cycle using carbon dioxide. A thermodynamic model for the cycle is proposed which can simulate the operation of a carbon dioxide refrigeration cycle. This model takes into account the practical effects of the thermo-physical properties of carbon dioxide …

Impacts Of Rainfall Events On Wastewater Treamtent Processes, Erin K. Mcmahan

USF Tampa Graduate Theses and Dissertations

Current research is revealing that stormwater can carry pathogens and that this stormwater is entering wastewater treatment facilities. During periods of intense rainfall, not only can stormwater carry higher amounts of pathogens, but it also increases the flow rate to the wastewater treatment facility. In many instances, the flow rate exceeds the facilities' treatment capacity and can impact treatment performance. The purpose of this study was to identify whether wastewater treatment is impaired during periods of increased rainfall, and to compare current policies that address this issue. The study was conducted using a case study approach to analyze historical precipitation …

Predicting Delinquency In Adolescence And Young Adulthood: A Longitudinal Analysis Of Risk And Protective Factors, Amy E. Green

USF Tampa Graduate Theses and Dissertations

Longitudinal studies that track individuals from childhood into adulthood may be the best method to identify risk and protective factors for crime and delinquency. The primary goals of this study were to determine 1) the ability of risk factors identified by the end of elementary school to predict delinquency referrals, 2) the extent to which positive assets (promotive factors) add to the prediction of delinquency, and 3) potential interactions between these risk and promotive factors that moderate the relationship between risk and delinquency referrals. The final purpose was to identify gender and racial differences in these relationships. The current study …

Joyce...Beckett...Dedalus...Molloy: A Study In Abjection And Masochism, Patricia A. Mccabe-Remmell

USF Tampa Graduate Theses and Dissertations

Irish male identity in James Joyce's and Samuel Beckett's novels shows evidence of abjection. The oppressive natures of the Church and State in Ireland contribute to abjection in some Irish men. Furthermore, the state of abject being can lead to masochistic practices. According to Julia Kristeva, abjection translates into a ìconceptual spaceî that has its roots in the Freudian Oedipal complex. Kristeva, following Lacan, also points to the connection between abjection and language. Joyceís character Stephen Dedalus and Beckettís Molloy/Moran both utilize this conceptual space and language in the narrative provides clues to their abject states. Joyceís A Portrait of …

Before The Inca: Prehistoric Dietary Transitions In The Argentine Cuyo, Nicole Shelnut

USF Tampa Graduate Theses and Dissertations

A dietary reconstruction was performed in order to understand changing prehistoric subsistence patterns in the Central Andean geographical area of the Argentine Cuyo that includes the provinces of San Juan and Mendoza. Archaeologically, the Cuyo is also known as a boundary between Andean agriculturalists and the foragers of Patagonia. One hypothesis being tested is whether this area was one of the last South American cultural groups to convert to maize cultivation, probably around 2000 BP. The process of stable isotope analysis is used to reconstruct the diets of individuals, as it reveals the relative proportions of C3 and C4 plants …

Viva Wallace Tampa Latins, The Politics Of Americanization, And The Progressive Party Campaign Of 1948, Jared G. Toney

USF Tampa Graduate Theses and Dissertations

This research deals with the presidential election of 1948 and the questions it raises concerning issues of ethnic identity and the experiences of working-class migrants in the U.S. South. Central to the discussion is the unprecedented success of third-party challenger Henry Wallace and his Progressive campaign in the immigrant enclaves of Tampa, Florida. Stigmatized by controversial foreign and domestic programs which drew disabling connections between Wallace and the Communist Party, the Progressive Party campaign hardly got its proverbial feet off the ground before falling victim to virulent criticism and widespread opposition. Carrying just over two percent of the votes nationwide, …

The True Picture Of The Indian—As Jackson Viewed It: The Portrayal Of Alessandro As An Atypical Native American, Carrie. Olin

USF Tampa Graduate Theses and Dissertations

Helen Hunt Jackson wrote the sentimental novel,

Ramona, to call attention to social justice for Native Americans. This thesis presents a reconsideration and reevaluation of the novel, especially that of the Native American voice the novel presents, by recognizing the complexities of Native American literature and culture. Previous criticism of the novel focuses on the portrayal of Hispanics or the "real life" events, such as the shaping of Southern California, the "true" Ramona, or the life of Jackson. Since there is little critical debate of the text itself, this thesis initiates further exploration. An extensive review of the scholarship …

Breaking Down The Wall: An Examination Of Mental Health Service Utilization In African American And Caucasian Parents, Idia O. Binitie

USF Tampa Graduate Theses and Dissertations

This study investigated the influence of parents' gender, race, and psychopathology on barriers and attitudes to mental health utilization for themselves and for their children. It was hypothesized that mothers and Caucasian¹ parents would have more positive attitudes and would perceive fewer barriers to mental health services than fathers and African American² parents. A total of 194 African American and Caucasian parents were recruited from the community to participate in this study. Parents completed measures on barriers and attitudes toward treatment for themselves and their children, utilization of mental health services for themselves and their children, and their own current …

Chronic/Life Threatening Illnesses From The Perspective Of Latino Men, Melissa Sierra

USF Tampa Graduate Theses and Dissertations

Much of the research on illness focuses on how people, particularly white men, cope with chronic/life threatening illnesses often adopting a "sick role" identity. For Latinos this type of identity transformation is complex as there is no place for dependency and passivity in traditional depictions of Latino masculinity. Latino men take pride in their manhood. As a result, they have trouble accepting their illness and the sick role. They do not tend to take their illness seriously, nor are they comfortable admitting to others the seriousness of their illness. My research focuses on how Latino men renegotiate a sense of …

Gender Differences In Age Of Onset For Delinquency:Risk Factors And Consequences, Laura M. Gulledge

USF Tampa Graduate Theses and Dissertations

The age of onset of delinquency has long been viewed as a primary indicator for further delinquency and criminality. However, studies on the risk factors for onset, and future delinquency have focused predominantly on males. The purpose of this study was to explore gender differences and similarities in risk factors for onset and frequency of arrest. The data used in these analyses were from a longitudinal study, Pathways to Adulthood: A Three Generational Urban Study, 1960-1994. Sixty-six percent (N=1,758) of the eligible children completed the final survey. Of these children, only 515 were used in this particular study because they …
