Relationship Of Waste Characteristics To The Formation Of Mineral Deposits In Leachate Collection Systems, Antonio J. Cardoso

USF Tampa Graduate Theses and Dissertations

Landfill leachate is generated as a result of reactions between water percolating through the landfill and wastes. Under normal conditions leachate is found at the bottom of landfills and from there, its movement can be controlled with collection systems to be treated, discharged, or recirculated. Landfill leachate collection systems are positioned above the liner and are designed to collect liquid under gravitational flow for the entire active, closure, and post-closure periods. Clogging of any portion of the system can lead to higher hydraulic heads and increase the potential for leakage through the liner.

To reduce the quantity of municipal solid …

Commensal Fecal Bacteria: Population Biology, Diversity, And Usefulness As Indicator Organisms In Reclaimed Water, Vasanta Lakshmi Chivukula

USF Tampa Graduate Theses and Dissertations

Water treatment facilities have been relying on indicator bacteria to assess the quality of water for decades. The purpose of this group of studies is to investigate the predictive capabilities of conventional and alternative indicators for pathogenic microorganisms in disinfection processes and treated wastewater effluents. In addition, the possibility that diversity of indicator bacteria, as well as overall bacterial diversity, correlate with fecal contamination in water bodies has been investigated. Indicator organisms (total coliforms, fecal coliforms, enterococci, C. perfringens, and coliphages) as well as pathogens (enteroviruses, Giardia, and Cryptosporidium) were enumerated from six wastewater treatment facilities at …

Sound Localization Abilities Of Two Florida Manatees, Trichechus Manatus Latirostris, Debborah E. Colbert

USF Tampa Graduate Theses and Dissertations

Florida manatees (Trichechus manatus latirostris) live in the shallow, often turbid inland and coastal waters of the southeastern United States. Since their vision is poor (Bauer et al., 2003), other senses probably guide orientation. Previous studies have found that manatees can hear over 40 kHz (Gerstein et al., 1999) and have the capacity for rapid auditory temporal processing (Mann et al., 2005). However, it is not known if manatees have the ability to localize underwater sounds.

Two Florida manatees were trained to identify underwater sound source locations using a four-choice discrimination paradigm. Three broad-band signals ( 0.2 - …

Promotoras Of The U.S.-Mexico Border: An Ethnographic Study Of Culture Brokerage, Agency, And Community Development, Ricardo B. Contreras

USF Tampa Graduate Theses and Dissertations

This study examines promotoras from the U.S.-Mexico border. Promotoras are women who live in colonias throughout the border area and who are employed by service provider and community development organizations to do health-related outreach and education with colonia residents. The role of promotoras can be seen from the perspective of culture brokerage; that is, they are mediators between local communities and external actors such as service providers and agencies of the government. As culture brokers, promotoras facilitate the relationship among the local communities, and the system of services and outside resources. The study proposes a conceptual framework through which programs …

Promoting And Preventing Alzheimer’S Disease In A Transgenic Mouse Model: Apolipoprotein E And Environmental Enrichment, David Antonio Costa

USF Tampa Graduate Theses and Dissertations

Besides age, inheritance of the apoE-ε4 allele is the main risk factor for late-onset AD. To determine the role of apoE in amyloid deposition, we studied mice expressing both mutant human amyloid ß-protein precursor (APP) and presenilin 1 (PS1) that were either normal or knocked-out for apoE. By 7 months, amorphous Aß deposition developed equally in both lines, indicating that Aß alone is sufficient for deposition to occur. In contrast, filamentous amyloid deposition was catalyzed at least 3000 fold by apoE. Electron micrographs further illustrate the filamentous nature of these plaques. These results and other, behavioral, data indicate that the …

The Outsider Within The Victorian Community: Nicholas Bulstrode In Middlemarch And Michael Henchard In The Mayor Of Casterbridge, Marian D. Conklin

USF Tampa Graduate Theses and Dissertations

Many have written about the theme of interconnection in George Eliot’s Middlemarch, where individual lives and fates are woven into the larger life of the community, but few have written about this theme in relation to The Mayor of Casterbridge, Thomas Hardy’s fictional and historical depiction of Dorchester and the larger area of Wessex. Hardy’s novel about “the life and death of a man of character,” is a complex and psychological characterization, but it also is representative of a particular province during a time of rapid change in community structure, just as Middlemarch is. I would like to …

Transformational Leadership, Leader-Member Exchange (Lmx), And Ocb: The Role Of Motives, Patrick W. Connell

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate the impact of employee motives regarding select leadership-OCB relationships. Based on previous research, it was hypothesized that the relationships observed between transformational leadership and various dimensions of OCB would be mediated by subordinate Organizational Concern. In contrast, the relationship between LMX-quality and subordinate Altruism was predicted to be either mediated or moderated by subordinate Prosocial Values.

Two hundred and one part-time and full-time employees (subordinates and supervisors) served as participants in this study, representing a total of 13 organizations in the Southeast United States. Results were based on a final sample of …

Antecedents And Consequences Of Emotional Dissonance: Understanding The Relationships Among Personality, Emotional Dissonance, Job Satisfaction, Intention To Quit And Job Performance, Laurie K. Diamond

USF Tampa Graduate Theses and Dissertations

The primary goal of this research was to explore the antecedents and consequences of emotional dissonance for debt collectors. The antecedents were personality factors (extraversion, anger, conscientiousness and agreeableness) and prosocial factors. The consequences of emotional dissonance were job satisfaction, intention to quit and job performance. A path model was developed to explain the relations among the studyís measures in a sample of 188 full-time debt collectors. The path analysis results failed to show strong relations between personality and emotional dissonance. However, strong relations were found between emotional dissonance, job satisfaction, intention to quit, and performance. Job satisfaction acted as …

USF Tampa Graduate Theses and Dissertations

This study investigates how hate crimes in general and anti-Arab hate crimes in particular were distributed across different regions of the United States during the 2001- 2002 period. The study explores how a historical event – the terrorist attacks against the U.S. on September 11, 2001 – and county population demographics affect the rates of hate crime against Arabs, Muslims or Middle Easterners. It was hypothesized that antiArab or anti-Muslim hate crimes displaced other forms of hate crime and were characterized by open acts of violence. According to the contact hypothesis, anti-Arab and anti-Muslim hate crimes would be more likely …

The Influence Of Stakeholder Groups On The Decision Making Process Regarding The Dead Zone Associated With The Mississippi River Discharge, Lisa M. Fairchild

USF Tampa Graduate Theses and Dissertations

The Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico represents the first national attempt to address this environmental issue. Hypoxia is the condition of low concentrations of dissolved oxygen in a body of water. This condition leads to a so-called “dead zone” and potentially threatens industries dependent on the living marine resources of this area. The potential impact of any policy or plan designed to combat hypoxia in the Northern Gulf of Mexico could have significant impacts on stakeholder groups, specifically the fishing industry in the Gulf of Mexico, and the agriculture and fertilizer …

Faculty Development Practices At Florida’S Public Community Colleges: Perceptions Of Academic Administrators, Faculty Development Practitioners, And Full-Time Faculty Members, Susan Sparling Finlay

USF Tampa Graduate Theses and Dissertations

Faculty development is a means by which institutions can assist faculty in addressing the challenges they face each day in the classroom. Certainly the importance of faculty development is never more evident than within community colleges where access is provided to all students through an open-door admission policy which often produces a more diverse student body creating numerous institutional challenges. Overtime, on many campuses, faculty development practices have come to play a prominent role in attending to these challenges.

Educational Outcomes For Children With Early-Onset Behavior Problems, Allison Gibson

USF Tampa Graduate Theses and Dissertations

Research has consistently shown a greater likelihood of negative outcomes later in life for children with early-onset behavior problems. Understanding the educational outcomes for these children is essential information that can help educators and families to provide targeted interventions in an effort to positively impact these at-risk children’s school experiences. The current study used archival data and a causal comparative research design to examine the educational outcomes (academic achievement, suspension rates, retention rates, and dropout rates/failure to complete high school) for children identified as at-risk for early-onset behavior problems in grades 1 through 3 for a cohort of children in …

Maximizing The Benefits Of Its Deployments Based On Idas Performance Measures And B/C Ratios, Cuthbert R. Gibson

USF Tampa Graduate Theses and Dissertations

Traditional transportation planning models are not very sensitive to many of the benefits derived from Intelligent Transportation Systems (ITS) technologies. With the recent availability of ITS Deployment Analysis System (IDAS), there is an opportunity to conduct detailed cost-benefit analyses of ITS Alternatives. IDAS is able to estimate the impacts, benefits, and costs resulting from the deployment of many ITS components. This is accomplished by comparing the average cost of deploying and integrating the appropriate technologies, to the estimated benefits experienced by the network. The ratio of average benefits to average costs is termed the B/C ratios. While the use of …

The Underdog Effect: Definition, Limitations, And Motivations. Why Do We Support Those At A Competitive Disadvantage?, Nadav Goldschmied

USF Tampa Graduate Theses and Dissertations

From politics to sports to business, people are quick to categorize those at a competitive disadvantage as ‘underdogs’. Moreover, there is ample anecdotal support that most people do not hesitate to align themselves with underdogs, a phenomenon called “the underdog effect”. A series of studies were conducted to examine the scope and limitations of the underdog effect. The first study explored the extent of the underdog effect and determined that resources play a crucial role in forming alliances with those whom we perceive to have the lower chance to succeed. A second series of experiments assessed whether participants, who demonstrated …

“Ethnographizing” Service-Learning: Creating Politically Engaged Anthropology, Wendy Ann Hathaway

USF Tampa Graduate Theses and Dissertations

Service-Learning is a popular teaching method that is increasingly being adopted by institutions of higher learning throughout the nation and is enthusiastically promoted as a progressive method for mediating the alleged decline in civic responsibility and ameliorating subsequent social ills. Servicelearning courses are also seen as an answer to growing student disinterest by connecting students to “real world” experiences while simultaneously providing much needed community support in the face of receding social services in this “Post-Welfare” moment (Goode and Maskovsky 2001a).

Anthropological insights, born out of a liberal humanistic tradition, can be employed to critically examine this popular educational and …

Fat Commentary And Fat Humor Presented In Visual Media: A Content Analysis, Susan Himes

USF Tampa Graduate Theses and Dissertations

In order to examine the phenomenon of fat messages presented through visual media, a content analysis was used to quantify and categorize fat-specific commentary. Fat commentary vignettes were identified using a targeted sampling procedure, and 135 scenes were excised from movies and TV shows. The material was coded by trained raters. Reliability indices were uniformly high for the seven categories (% agreement ranged from .90-.98; kappas ranged from .66-.94). Results indicated that fat commentary and fat humor is often verbal, directed toward another person, and is often presented directly in the presence of the overweight target. Results also indicated that …

“The Wil Of His Wif:” Discourse, Power, And Gender In Chaucer’S The Tale Of Melibee, Sara D. Jenkins

USF Tampa Graduate Theses and Dissertations

In the Tale of Melibee, Chaucer gives us an excellent illustration of a point French theorist Michel Foucault would make centuries later: That power is something that moves and shifts between people and within institutions, that it is not fixed nor permanent, that it is used as needed toward specific ends, and that it is enacted through the medium of discourse. In Melibee, Melibee’s wife Prudence achieves a place of authority and influence in her marriage via her use of discourse, and specifically by using a more “male” way of speaking. Chaucer is often considered feminist-friendly due to …

Systematic Study Of Amyloid Beta Peptide Conformations: Implications For Alzheimer’S Disease, Jeffy Pilar Jimenez

USF Tampa Graduate Theses and Dissertations

The amyloid beta peptide particularly the 40 and 42 amino acid residues are the responsible for plaque formation in Alzheimer's disease (AD) patients. Extra cellular plaque formation has been recognized after incessant investigations along with the formation of intracellular tau protein tangles as the hallmarks of AD. Furthermore, the plaque formation has been linked mostly as a cause of the disease and the tangles mostly as a consequence. Our investigation is focused on studying the formation of AD plaques. The amyloid beta (Aß) is a physiological peptide secreted from neurons under normal conditions, along with other soluble forms cleaved from …

Simulating The Electric Field Mediated Motion Of Ions And Molecules In Diverse Matrices, Joseph Hickey

USF Tampa Graduate Theses and Dissertations

Electroporation is a methodology for the introduction of drugs and genes into cells. This technique works by reducing the exclusionary nature of the cell membrane [125, 129, 186, 189]. Electroporation has successfully been used in electrochemotherapy and electrogenetherapy [57, 68, 86, 87, 110, 112, 131]. The two major components of electroporation are an induced transmembrane potential and the motion of the deliverable through a compromised cell membrane into the target cell [38, 55, 62, 114, 131]. These two components are both dependent on the electrophoretic motion of charged species in an applied electric field [45, 64, 75, 77, 177].

The Benefits Of Clear Speech At Normal Rates For Older Listeners With Normal Hearing, Athina Panagos Panagiotopoulos

USF Tampa Graduate Theses and Dissertations

Clear speech is a type of speaking style that improves speech intelligibility for many individuals. For example, one study showed a 17 percentage point increase in intelligibility over conversational speech for individuals with sensorineural hearing loss (Picheny et al., 1985). The clear speech benefit also extends to children with learning disabilities (Bradlow et al., 2003), non-native listeners (Bradlow & Bent, 2002), and other populations. Although clear speech is typically slower than conversational speech, it can be produced, naturally, at normal rates with training. For young listeners with normal hearing, clear speech at normal rates (clear/normal) is more intelligible than conversational …

Performativity And The Latina/O-White Hybrid Identity: Performing The Textual Self, Shane T. Moreman

USF Tampa Graduate Theses and Dissertations

This study is an exploration of Latina/o-White hybrid identity for constructions and negotiations of hybridity as performed in the lives of individuals and as rearticulated in discourse. These discourses are drawn from interviews with nine individuals, stories of my own life, and three published memoirs. Despite these different forms, all the selfidentified Latina/o-White hybrid individuals speak to the difficulty of imagining and enacting a hybrid identity within today’s discourse on race and ethnicity. This study articulates these difficulties as lived experience, theory, and performance come together to argue for and against hybridity as a model for contemporary identity. The project …

The Impact Of Privatization Of Primary Care Programs In Large County Health Departments In Florida, Arlesia Lynn Brock

USF Tampa Graduate Theses and Dissertations

Since the mid-1970s, top managers, politicians, and officials in both public and private institutions have promoted contracting-out services (privatization) as a means of increasing efficiency, flexibility, and quality. The privatization trend has occurred in many public sector organizations particularly in city services and prisons. Public health services are not immune to this trend. Today many county health departments have contracted the provision of public health services like womens health, primary care, and laboratory services. However, very few studies have analyzed the impact of these privatizations on cost, access, and health outcomes. Proponents favoring the private provision of these services argue …
