The Interplay Of Economic, Climatic And Cultural Change Investigated Through Isotopic Analyses Of Bone Tissue: The Case Of Sardinia 4000-1900 Bc, Luca Lai

USF Tampa Graduate Theses and Dissertations

With the broader aim of reconstructing long-term resource use and ecological history for better policy making in times of environmental change, this study is an attempt to decode the mutual effects of human subsistence practices, climate and socio-cultural organization in Sardinia between 4000 and 1900 BC. Was economy changing due to climate change? Was the environment changing due to economic practices? And how were economic practices and socio-cultural factors interacting? The answer is complex, and some convergence of complex systems theory, historical ecology and agency supports this. Diet, at the interface of all of these as fulfilling biological needs constrained …

The Influence Of Anxiety And Depression On Cognitive Functioning In Parkinson’S Disease, Lynn E. Oelke

USF Tampa Graduate Theses and Dissertations

Depression and anxiety are common psychiatric disturbances in Parkinson's disease (PD). Past studies have demonstrated a relationship between depression and cognitive decline in PD; however, the unique influence of anxiety has not been well studied. The objective of the present study was to differentiate the unique influences of depression and anxiety on cognitive functioning in PD. Sixty-eight cognitively intact PD patients with mild to moderate motor disease severity completed self-report questionnaires and neuropsychological tests. Two hierarchical regression analyses were conducted with executive functioning performance as the criterion variable, and two additional hierarchical regression analyses were conducted with memory performance as …

Analysis Of Glycerol 3-Phosphate Dehydrogenase And Sarco/Endoplasmic Reticulum Calcium Ion Channel Atpase For Use In Deep Metazoan Phylogenetics, Terry G. Campbell

USF Tampa Graduate Theses and Dissertations

Genetic sequence data have been widely used to analyze metazoan phylogenies for two decades, and numerous datasets have been generated for testing relationships at many different taxonomic levels. The rapid divergence of major metazoan body plans during the Cambrian explosion confounds the determination of phylogenetic relationships among metazoan phyla. Few molecular analyses at this level have used both multiple genes and broad taxonomic representation. Furthermore, most studies have relied exclusively on the small ribosomal subunit rRNA gene (SSU). Many of the other genes that have been examined have possessed substitution rates that are inappropriate for resolving the relationships among metazoan …

Representation And Learning For Sign Language Recognition, Sunita Nayak

USF Tampa Graduate Theses and Dissertations

While recognizing some kinds of human motion patterns requires detailed feature representation and tracking, many of them can be recognized using global features. The global configuration or structure of an object in a frame can be expressed as a probability density function constructed using relational attributes between low-level features, e.g. edge pixels that are extracted from the regions of interest. The probability density changes with motion, tracing a trajectory in the latent space of distributions, which we call the configuration space. These trajectories can then be used for recognition using standard techniques such as dynamic time warping. Can these frame-wise …

Re-Islamization In Higher Education From Above And Below: The University Of South Florida And Its Global Contexts, Terri K. Wonder

USF Tampa Graduate Theses and Dissertations

This study explores Islamism's interplay with higher education as the movement advances an agenda for worldwide reformation. Over an eighty-year period, Islamism has appropriated higher education institutions, professional associations, on- and off-campus organizations, and publications as a primary means to achieve its utopian objective of the Nizam Islami, or "Islamic Order." Findings show how the Muslim Brotherhood in Egypt developed a Weberian bureaucratic organizational and administrative structure to exert influence not only in Egypt but also the world. A Qutb-inspired "hijra" of Muslim Brothers in universities proved itself adroit at filling macro-and micro-level policy vacuums in Soviet-aligned post-colonial societies, marginalizing …

Transition Experiences Of Selected Emerging Adults With Emotional And Behavioral Difficulties In Higher Education, Kathleen M. Fowler

USF Tampa Graduate Theses and Dissertations

Transitioning into adulthood is an exciting and challenging time for emerging adults, and is even more difficult for young adults with emotional and behavioral difficulties (EBD). Even though the number of transition-aged individuals with EBD is significant, few studies have explored the experiences of this population engaged in educational activities, and there is limited information regarding the personal experiences of emerging adults with EBD. The purpose of the study is to acquire a better understanding of the experiences of young adults diagnosed with an EBD who are working toward their academic goals. Further, this study may give voice to individuals …

A Novel Biostable 3d Porous Collagen Scaffold For Implantable Biosensor, Young Min Ju

USF Tampa Graduate Theses and Dissertations

Diabetes is a chronic metabolic disorder whereby the body loses its ability to maintain normal glucose levels. Despite of development of implantable glucose sensors in long periods, none of the biosensors are capable of continuously monitoring glucose levels during long-term implantation reliably. Progressive loss of sensor function occurs due in part to biofouling and to the consequences of a foreign body response such as inflammation, fibrosis, and loss of vasculature.

In order to improve the function and lifetime of implantable glucose sensors, a new 3D porous and bio-stable collagen scaffold has been developed to improve the biocompatibility of implantable glucose …

The Effects Of A Structured Adherence Intervention To Haart On Adherence And Treatment Response Outcomes, Donald E. Kurtyka

USF Tampa Graduate Theses and Dissertations

Background: Adherence to antiretroviral (ARV) medications in excess of 90-95% is necessary for optimal response to suppress HIV replication and to maintain and/or restore immune function. A number of interventions have been shown to improve ARV adherence, but no research has been conducted which evaluates proactive monitoring of pharmacy refill adherence and subsequent intervention when inadequate adherence is identified.

Purpose: The purpose of this project was to compare treatment response, pharmacy refill adherence and self-reported medication adherence between two groups of patients: those participating in an AIDS Drug Assistance Program (ADAP) and those participating in a Medicaid-funded medication access program. …

Privacy In Database Designs: A Role Based Approach, Gary A. Poe

USF Tampa Graduate Theses and Dissertations

Privacy concerns have always been present in every society. The introduction of information technology information has enabled a reduction in the cost of gathering information, management of that information and the permitted that same information to become increasingly portable. Coupled with these reductions of cost has been an increase in the demand for information as well as the concern that privacy expectations be respected and enforced through security systems that safeguard access to private-type data. Security systems enforce privacy expectations. Unfortunately there is no consensus on a definition of privacy making the specification of security often over broad and resulting …

Parent-Child Interaction Therapy For Children Diagnosed With Reactive Attachment Disorder, Demetria Soulounias-Arriaga

USF Tampa Graduate Theses and Dissertations

Parent-Child Interaction Therapy is a probably efficacious, evidenced-based

treatment, which has been proven to decrease problem behaviors of children, as well as

improve parent-child interactions. The first phase is the Child-Directed Interaction (CDI),

which allows the child to lead the play session, while parents are taught to interact

without giving demands, asking questions, or providing criticism. According to the

DSM-IV-TR, Reactive Attachment Disorder is a rare diagnosis. Many attachment

therapists indicate that traditional approaches to treatment have not been demonstrated as

being effective with these children. This study will examine the CDI phase of Parent-

Child Interaction Therapy as a …

How Similar Are Personality Scales Of The “Same” Construct? A Meta-Analytic Investigation, Victoria L. Pace

USF Tampa Graduate Theses and Dissertations

In recent years, meta-analytic reviews have estimated validities for the use of personality scales in the prediction of job performance from an array of empirical studies. A variety of personality measures were used in the original studies, and procedures and decisions concerning the categorization of these measures into Big Five personality factors have differed among reviewers. An underlying assumption of meta-analysis is that the predictors across included studies are essentially the same, as is the criterion. If this is not the case, then problems arise for both theoretical reasons and practical applications. If predictors that are not highly correlated are …

Reforming Dance Pedagogy: A Feminist Perspective On The Art Of Performance And Dance Education, Jennifer Clement

USF Tampa Graduate Theses and Dissertations

Dancers, in their formal training, are deprived of many basic human experiences and are often not exposed to critical thinking. Expectations about what it means to dance and/or be a dancer shape the classroom environment, performances and both the body and mind of individuals engaged in this particular art form. A professional dancer is expected to plan her day around the dance classroom and this mentality is shared by aspiring professionals as well as dance educators. This structure, in tandem with the expectations for a female dancer to maintain a certain body type- almost always a thin flexible body, toned …

Patient care programs such as wellness, preventive care and specifically disease management programs, which target the chronically ill population, are designed to reduce healthcare costs and improve health, while promoting the efficient use of healthcare resources, and increasing productivity. The organizational form adopted by the health plan for these programs, i.e. in-sourced vs. outsourced is an important factor in the success of these programs and the extent to which the core objectives listed above are fulfilled.

Transaction cost economics aims to explain the working arrangement for an organization and to explain why sourcing decisions were made by considering alternate organizational …

The Validity Of Personality Trait Interactions For The Prediction Of Managerial Job Performance, Amy M. Taylor

USF Tampa Graduate Theses and Dissertations

Personality variables have been shown to be significant predictors of job performance (Barrick & Mount, 1991; Tett, Jackson, & Rothstein, 1991). Recent advances in methodology for analyzing personality-job performance relationships indicate that interactions among traits may yield incremental validity. Job types in which performance has been shown to relate to trait interactions include clerical jobs, jobs with high interpersonal components, and jobs in realistic and conventional contexts, (Witt, Burke, Barrick, & Mount, 2002; Burke & Witt, 2002; and Burke & Witt, 2004). This study examined the validity of trait interactions for the prediction of managerial job performance. Hypotheses included a …

"Under The Bloody Hatchet Of The Haitians": Thomas Jeffersonís Foreign Policy Concerning The Haitian Revolution, 1791-1806, Joseph A. Boyd

USF Tampa Graduate Theses and Dissertations

At first glance Thomas Jefferson's presidential actions concerning the Haitian Revolution seem to denote racially motivated decisions predicated upon fear. However, through a deeper analysis of primary documents, Jefferson's position appears more economically and politically ambitious. By 1791, the French colony of Saint Domingue held the title of the richest colony in the Caribbean and the world's leading producer of sugar. In addition, Saint Domingue consumed about sixteen percent of all of America's exports. Jefferson's personal opinions concerning revolution and trade on the island of Saint Domingue contradict the statements of his administration. Partisan politics manifested a stern voice within …

Effects Of Nutrients From The Water Column On The Growth Of Benthic Microalgae In Permeable Sediments, Brian P. Darrow

USF Tampa Graduate Theses and Dissertations

In some continental shelf sediments integrated benthic microalgal biomass is greater than the integrated phytoplankton biomass in the overlying water column. In addition, benthic microalgae may account for up to 10% of the primary production responsible for the coastal fishery yield of the eastern United States.

A three-dimensional model of the eastern Gulf of Mexico examines the effects of water-column nutrient sources on the growth of benthic microalgae. To parameterize the exchange of nutrients across the sediment/water interface in these permeable sediments, a non-local exchange submodel was constructed and tested within the framework of the model's grid.

Based on the …

Nanoelectronic device modeling integration in mixed signal systems is reported. The modeling results are compatible with standard hardware …

Examining Physicians’ Motivations To Volunteer: An Applied Visual Anthropological Approach, Jess Paul Ambiee

USF Tampa Graduate Theses and Dissertations

In the U.S., the number of persons who cannot afford health care continues to rise. Providing a "safety net" for such persons is becoming increasingly important. Medical professional volunteerism provides access to health care for people who have little or no access to health care otherwise.

At a not-for-profit free health clinic in Tampa, Florida, hundreds of physicians have volunteered their time in an attempt to reduce the health care gap in their community. The clinic sees thousands of persons who have very limited options in regards to their health care. This study investigates the reasons physicians volunteer and the …

Development Of A Scale To Measure Parenting In Hispanic Adolescents’ Families, Evelyn Marie Alvarez

USF Tampa Graduate Theses and Dissertations

The ultimate goal of this research was to provide a tool to adequately examine the relationship that parenting style has with Hispanic youths' academic and behavioral outcomes. A review of the literature reveals that the field is lacking an appropriate, culturally sensitive, paper-and-pencil measure of parenting of Hispanic adolescents with adolescents reporting on their parents' behavior. Current measures were not developed with Hispanic families in mind, but rather were evaluated for use with Hispanic populations after the development phase. Therefore, the current study sought to fill this gap in the research on parenting by constructing a measure of parenting that …

Corrosion Assessment Of Mechanically Formed Aluminized Steel, Mersedeh Akhoondan

USF Tampa Graduate Theses and Dissertations

Ribbed steel pipes made of Type 2 aluminized steel are commonly used for culvert pipes for highway drainage. Typically aluminized steel pipes have shown good durability and are expected to have long service life, e.g. 75 years; also, they are used in a wide variety of soil and water conditions. However, early corrosion of aluminized steel pipes has been recently observed in some inland locations. Initial observations showed severe corrosion in forms of pits, both along the ribs and at the nearby flat portions of the pipes. It is critical to determine the cause of early deterioration and establish methods …

Measuring Diversity Management Skill: Development And Validation Of A Situational Judgment Test, Andrew Biga

USF Tampa Graduate Theses and Dissertations

As a result of both demographic and social changes in the U.S., organizations have become much more diverse. Diversity presents unique challenges for management as it is linked to both positive and negative organizational performance outcomes (Mannix & Neale, 2005). Diversity, by itself, may not be sufficient to achieve competitive advantage. Effective diversity management becomes an important issue for organizations to consider. The current research uses Situational Judgment Test (SJT) methodology to develop an assessment measuring Diversity Management Skill. The development of a SJT involves a three-step process: Creation of critical incidents, generation of response options, and use of SME …

Reading Fluency Through Alternative Text: Rereading With An Interactive Sing-To-Read Program Embedded Within A Middle School Music Classroom, Marie Biggs

USF Tampa Graduate Theses and Dissertations

Singing exaggerates the language of reading. The students find their voices in the rhythm and bounce of language by using music as an alternative text. A concurrent mixed methods study was conducted to investigate the use of an interactive sing-to-read program Tune Into Reading (Electronic Learning Products, 2006) as an alternative text, embedded within a heterogeneous music classroom. Measured by the Qualitative Reading Inventory-4 (QRI-4) (Leslie & Caldwell, 2006), the fluency, word recognition, comprehension, and instructional reading level of the treatment students were compared to their counterparts who sang as part of the regular music program. Concurrently, this investigation also …
