Gender Stereotypes Of Citizenship Performance And Their Influence On Organizational Rewards, Lisa Wilkinson

USF Tampa Graduate Theses and Dissertations

Gender differences were investigated on ratings of citizenship performance (altruistic behaviors in the workplace). Self, peer, and supervisor ratings were collected on the three dimensions of citizenship performance (personal support, organizational support, and conscientious initiative) with scale type and gender as possible moderators of citizenship performance ratings.

Two hundred and twenty-four individuals performance ratings were collected, from different companies across the United States. The majority of these participants were white and female, and the largest industry sampled was the customer service industry. Participants were asked to complete a performance rating about themselves and have their peers and supervisor evaluate their …

Teaching Excellence: Perceptions Of Community College Students, Gary Robert Oesch

USF Tampa Graduate Theses and Dissertations

Numerous efforts to assess teaching excellence have been attempted, but systematic research has produced limited results at best. This study expanded upon recent studies focusing on how students' perceptions and attitudes can be used to identify the best course environments and the qualities of teaching excellence. This is especially critical considering that most previous empirical research has been conducted at the university level, while community colleges have been mostly overlooked. Thus, little is know about community college students' perceptions of teaching excellence. To assess their views of teaching excellence, a questionnaire was given to students from one community college to …

Discourse And Disconnect: Black Teachers And The Quest For National Board Certification, Paula J. Leftwich

USF Tampa Graduate Theses and Dissertations

Discourse and Disconnect: Black Teachers and the Quest for National Board Certification Paula J. Leftwich ABSTRACT Black teachers have been under-represented proportionate to their presence in the teaching population in both the application for and achievement of certification by the National Board for Professional Teaching Standards. This study sought to explore the possibility of a disconnect between the discourses of Black teachers and the discourses of the National Board Certification process. Further, it was designed to investigate the effectiveness of targeted mentoring strategies to increase the participation rate and achievement rate of Black teachers in this complex and lengthy process. …

The Early Ontogeny Of Feeding In Two Shark Species: Developmental Aspects Of Morphology, Behavior, And Performance, David C. Lowry

USF Tampa Graduate Theses and Dissertations

Early ontogeny is a time of rapid anatomical and behavioral development in most organisms. The degree of synchrony between form and function during this period, and the concomitant performance consequences, can strongly impact individual survival. Understanding the development of feeding during early ontogeny is important because nutrient acquisition universally influences organismal biology. A one-year, longitudinal feeding study was conducted for two elasmobranch species that were selected for their disparate morphology, behavior, and habitat: the whitespotted bambooshark Chiloscyllium plagiosum and the leopard shark Triakis semifasciata. To quantify changes in cranial morphology, external attributes of the feeding apparatus were measured weekly. …

An Empirical Examination Of Job Stress And Management Of Emotionally-Based Behavior: Frontline Social Service Personnel Perspective, Doreen Sams

USF Tampa Graduate Theses and Dissertations

Frontline service personnel (FSP) play an invaluable role in the marketing mix by directly influencing the customers perception of both the service organization as well as the service quality during the face-to-face delivery service encounter (Ashforth and Humphrey 1993). The purpose of this dissertation is to examine how sources of job stress for FSP such as perceived customer demands, role ambiguity, role conflict, role overload, and emotional labor and various mediators such as job autonomy, emotional intelligence, and emotion-focused coping directly and indirectly influence job stress and outcome variables such as attitudes, behaviors, physical consequences, emotional exhaustion, job performance, and …

Effects Of Long-Term Administration Of Caffeine In A Mouse Model For Alzheimer’S Disease, William Schleif

USF Tampa Graduate Theses and Dissertations

A recent epidemiological study suggested that higher caffeine intake reduces the risk of Alzheimer's disease (AD). Caffeine, a widely consumed stimulatory drug, is a non-selective adenosine receptor antagonist that has been shown to increase plasma adenosine levels in rodents. To determine any long-term protective effects of caffeine in a controlled longitudinal study, caffeine was added to the drinking water of APP_sw transgenic (Tg) mice between 4 and 9 1/2 months of age, with behavioral testing done during the last 6 weeks of treatment. The average daily intake of caffeine per mouse (1.5 mg) was the human equivalent of 5 …

Does Agreeableness Help A Team Perform A Problem Solving Task?, Frederick R. B Stilson

USF Tampa Graduate Theses and Dissertations

The relationship between mean team Agreeableness and team performance has not been shown definitively. The present study was performed looking at archival data from a study that assessed team performance from 62 two person teams using the DDD and involving two types of training and two types of information probes during the computer task. In addition, each of the participants took a personality test based on the IPIP with an emphasis on Agreeableness and its 6 facets. Using HLM analysis, it was determined that Agreeableness does not have a significant effect on team performance for a problem solving tasks (delta …

Molecular Subtyping And Antibiotic Resistance Analysis Of Salmonella Species, Aparna Tatavarthy

USF Tampa Graduate Theses and Dissertations

The genus Salmonella, comprised of 2400 serotypes, is one of the leading causes of foodborne illnesses in the US and has been used for the deliberate contamination of food. A rapid system for detection, isolation, typing and antibiotic susceptibility profiling is essential for diagnosis and source tracking in natural outbreaks or a bioterrorism event. Pure culture is essential for molecular typing and antibiotic resistance testing. The virulence and the resistance mechanisms of Salmonella are rapidly evolving and many are still unexplained. The first aim of the study was to rapidly detect and isolate Salmonella from intentionally contaminated food. The …

An Exploration Of The Lumbar Loads And Affective Responses To Lumbar Pain On Lower Limb Amputees Who Use A Prosthesis, Tracy Ann Perrotti

USF Tampa Graduate Theses and Dissertations

80% of the American population experiences back pain and it is the most common cause of limited activity in people of age 45 and under. Determining the reasons for back pain and developing new ways to treat it have been extensively researched over the past decade. However, very little research has been done on low back pain of amputees.

There are four million existing amputees living in America and 250,000 people become new amputees each year. 70% of this group is lower limb amputees and a large number use a prosthesis of some kind to aid in the functions of …

Automatic Attention To Aggression Cues And Alcohol Cues Using A Dichotic Listening Task And A Parafoveal Visual Task, Michelle Edington Levasseur

USF Tampa Graduate Theses and Dissertations

Ongoing investigations of drunken aggression tend to focus on 1) situational cues, and 2) individual variables such as personality traits. This study investigated the hypothesis that an undergraduates attention would be pulled toward a nonconscious presentation of aggression stimuli, especially in the presence of alcohol cues, and especially if he or she was high on trait anger [as measured using the State Trait Anger Expression Inventory (STAXI); Spielberger, 1988] and had high expectancies for behaving aggressively while drinking alcohol [as measured using the Expectancy Questionnaire for Alcohol and Aggression Lo Dose (EQAAL); Epps, Hunter, LeVasseur, Steinberg, and Hancock, unpublished manuscript]. …

Microfinance In Neoliberal Times: The Experience Of An Egyptian Ngo, Sarah A. Tobin

USF Tampa Graduate Theses and Dissertations

Development non-governmental organizations (NGOs) are under immense pressure to adhere to the programs and methods put forth by external donors, particularly if the NGOs rely on the funding to sustain their own organizations. Those external donors that represent neoliberal ideologies and enforce neoliberal practices, particularly in the area of microfinance, maintain a power that most recipient NGOs cannot evade. This becomes a difficult position for the NGOs to navigate as they try to accomplish good work in their communities. This research project is a study into the experience of one NGO, the Egyptian Development Organization (EDO), as it implemented microfinance …

Sexual Functioning In Breast Cancer Survivors, Heidi M. King

USF Tampa Graduate Theses and Dissertations

Breast cancer diagnosis and treatment has been suggested to effect sexual functioning. Little is known about how breast cancer patients compare to women without a history of cancer on measures of sexual functioning, as well as the psychological and physical factors may contribute to these difficulties. To address these issues, 71 breast cancer patients and 40 of their nominated friends were recruited and served as participants. All women received and returned via the mail measures on general background information, depression, fatigue, marital satisfaction, body image, vaginal symptoms, and sexual functioning. All the psychological and physical variables assessed correlated with a …

Monte Carlo Simulations As A Tool To Optimize Target Detection By Auv/Rov Laser Line Scanners, Martin Alejandro Montes

USF Tampa Graduate Theses and Dissertations

The widespread use of laser line scanners (LLS) aboard unmanned underwater vehicles in the last decade has opened a unique window to a series of ecological and military applications. Variability of underwater light fields and complexity of light contributions reaching the receiver pose a challenge for target detection of LLS under different environmental conditions. The interference of photons not originating at the target (e.g. water path, bottom) can often be minimized (e.g., time-gated systems) but not excluded. Radiative transfer models were developed to better discriminate noise components from signal contributions at the receiver for two continuous LLS: Real-time Ocean Bottom …

Stress And Cognitive Performance In Older Adults, Christopher B. Rosnick

USF Tampa Graduate Theses and Dissertations

The current dissertation sought to examine stress in three different, but overlapping, ways. The first study examined how self-reported negative life events, in the aggregate and individually, are associated with cognitive performance. The results suggested that there was no significant relationship between the aggregate measures of self-reported negative life events and cognitive performance. On the other hand, several individual negative life events were associated with cognitive functioning. The findings support previous research indicating that using estimates of individual stressors rather than aggregate measures of stressors increases the predictive validity of stress measurement.

The second study assessed the cross-sectional and longitudinal …

Zooplankton Of The West Florida Shelf: Relationships With Karenia Brevis Blooms, Kristen M. Lester

USF Tampa Graduate Theses and Dissertations

Blooms of the toxic dinoflagellate Karenia brevis are common on the West Florida Shelf (WFS), yet little is known of the relationships between zooplankton and K. brevis. A comprehensive analysis was undertaken to examine 1) perturbations in zooplankton community composition within K. brevis blooms 2) the contribution of zooplankton ammonium and phosphate excretion to K. brevis bloom nutrient requirements, and 3) the role of zooplankton grazing in K. brevis bloom termination. Prior to undertaking the first portion of the study, an examination of the perturbations in the normal zooplankton assemblage within K. brevis blooms, it was first necessary to …

Characterizing Sound Production In Nearshore Rockfishes (Sebastes Spp.), Bryan Nichols

USF Tampa Graduate Theses and Dissertations

Rockfishes of the genus Sebastes are trophically important in most nearshore environments of the west coast of North America, and support important commercial and recreational fisheries. Though the 72 northeast Pacific species have drumming muscles along their swim bladders, little is known about sound production in the genus. Sounds produced by nearshore rockfish were recorded using fixed hydrophones and underwater video in aquaria, and acoustical dataloggers in the field. Sounds were analyzed from six species: Sebastes nebulosus, S. atrovirens, S.carnatus, S. chrysomelas, S. caurinus, and S.maliger. These six species are closely related, mostly bottom …

Reliability Of Liquid Core Optical Waveguides For Sensitive Optical Absorption Measurements Of Trace Species In Water, Avishekh Pal

USF Tampa Graduate Theses and Dissertations

Long path optical waveguides can be used in optical absorption measurements to increase the optical path length and, thus, the overall absorption of a sample. Recently, 1m long coiled Liquid Waveguide Capillary Cells (LWCC) have been used by analytical spectroscopists to measure the absorption strength of weakly absorbing liquids. However, most of these measurements have used conventional light sources such as Xenon or Halogen lamps and not spectroscopic laser sources.

In this thesis study, we used a LWCC absorption waveguide and a laser light source to measure, for the first time to our knowledge, the optical transmission through several water …

The Compositional Style Of Francesco Geminiani: A Reflection Of Theory And Practice In His Music And Guida Armonica Treatise, Valerie R. Weber

USF Tampa Graduate Theses and Dissertations

Francesco Geminiani was highly regarded as a violinist, composer, and theorist during the late Baroque era. During his lifetime he was considered equalin status to the foremost composers of the day; however, relatively little information is available regarding his life and works today. This lack of information is largely a result of controversy among his peers regarding the merit of his work, specifically in reference to melodic style, structural consistency and harmonic practices. Critical views of such authors as Sir John Hawkins and Charles Burney have been reflected in later historical writings, considerably suppressing further interest in the composer.

The …

Expanding The Science Of Successful Aging: Older Adults Living In Continuing Care Retirement Communities (Ccrcs), Kathryn H. Petrossi

USF Tampa Graduate Theses and Dissertations

Rowe and Kahns theory of successful aging identifies three main components of aging successfully: reducing the risk of disease and disability, maintaining high cognitive and physical function, and engagement with life. While there is compelling evidence that suggests the legitimacy of this concept in the 50-75 year old community dwelling population, three areas of expansion are necessary: 1.) programmatic research; 2.) extending the existing research samples to include older samples and those living in continuing care retirement communities (CCRCs); and 3.) the integration of data collection and analysis to move beyond investigation of just one successful aging outcome to include …

Changes In The Perception And Sense Of Self Of Individuals With Aphasia: An Ethnographic Study, Erline Vieira Nakano

USF Tampa Graduate Theses and Dissertations

Little is known about the perceived changes in identity and sense of self in individuals with aphasia. Seminal research using qualitative methods and personal narratives has been conducted in England regarding the experience of living with aphasia (see for instance Parr, Byng, Gilpin & Ireland, 1999; Parr, Duchan & Pound, 2003; Byng, Pound & Hewitt, 2004), but the use of such methodologies is still emergent in the United States. In addition, despite the great achievements of the disabilities movement in countries such as the U.S. and the U.K., individuals with aphasia have remained largely at the margins due to the …

Tardigrade Evolution And Ecology, Phillip Brent Nichols

USF Tampa Graduate Theses and Dissertations

A character data set suitable for cladistic analysis of tardigrades at the family level was developed. The data matrix consisted of 50 morphological characters from 15 families of tardigrades and was analyzed by maximum parsimony. Kinorhynchs, loriciferans and gastrotrichs were used as outgroups. The results agree with the currently accepted hypothesis that Eutardigrada and Heterotardigrada are distinct monophyletic groups. Among the eutardigrades, Eoyhypsibiidae was found to be a sister group to Macrobiotidae + Hypsibiidae, while Milnesiidae was the basal eutardigrade family. The basal heterotardigrade family was found to be Oreellidae. Echiniscoideans grouped with some traditional Arthrotardigrada (Renaudarctidae, Coronarctidae + Batillipedidae) …

A Quantitative Assessment Of Public Relations Practitioners’ Perceptions Of Their Relationship With The Organization They Represent, Jill Boudreaux

USF Tampa Graduate Theses and Dissertations

This study attempts to identify how public relations practitioner roles and organizational decision-making style impact the relationship that is shared between the practitioner and the organization they represent. Based on Internet survey research methods, research findings indicated that organizational decision-making style was a minimal factor in influencing the relationship shared between the practitioner and the organization they represent. Practitioner role did, however, have a significant influence on the levels of trust, commitment, satisfaction and control mutuality between the practitioner and the organization they represent. Low response rates prevents confident generalization of the results of this study to the entire Public …

Sigma Receptors Modulation Of Voltage-Gated Ion Channels In Rat Autonomic Neurons, Hongling Zhang

USF Tampa Graduate Theses and Dissertations

Sigma receptors have been implicated in the regulation of the cardiovascular system. Some of the cardiovascular effects of sigma receptors may be through the modulation of autonomic neurons. Studies on the expression and cellular function of sigma receptors in autonomic neurons were conducted in neonatal rat intracardiac (ICG) and superior cervical ganglia (SCG).

Individual neurons from SCG and ICG were shown to express transcripts encoding the sigma-1 receptor. The effects of sigma receptors activation on high-voltage-activated Ca²⁺ channels was studied in isolated neurons of these ganglia. Bath application of sigma receptor agonists depressed peak calcium channel currents in a …

Preservice Teachers’ Belief Development While Learning To Teach Writing In An Elementary Writing Methods Course, Karen S. Kelley

USF Tampa Graduate Theses and Dissertations

My study examined the belief development of three preservice teachers as they learned to teach writing in a one-semester elementary writing methods course. I also sought to identify significant episodes that contributed to the preservice teachers’ belief development. Two questions guided my inquiry: How do preservice teachers’ beliefs about writing and the teaching of writing develop while enrolled in an elementary writing methods course? and What episodes do preservice teachers, who are enrolled in an elementary writing methods course, view as significant in helping them negotiate their beliefs about writing and writing instruction? I collected survey data, conducted a series …

Stimulation Of Nitrification By Carbon Dioxide In Lab-Scale Activated Sludge Reactors, Lina Posso-Blandon

USF Tampa Graduate Theses and Dissertations

Wastewater treatment plants (WWTPs) are required to remove ammonium (NH₄⁺) from wastewater due to its oxygen demand and toxicity to the aquatic organisms. Ammonium is removed in the activated sludge treatment system by nitrification and denitrification processes. Nitrification is the oxidation of NH₄⁺ to nitrate (NO₃^-) by autotrophic nitrifying bacteria which use carbon dioxide (CO₂) as a carbon source for growth. These bacteria grow slowly with low nitrification rates limiting WWTPs capacity. In this research it was hypothesized that supplying higher concentrations of CO₂ during aeration increases nitrification rates, …
