The study was conducted over a four-month period from May-August of 2011, and it was divided into two stages. The first stage of the project consisted of volunteer participation with dengue fever surveillance brigades in the three communities with the highest incidence of dengue fever during the beginning of 2011. This initial stage employed participant observation as its research method. The second stage was conducted in a different community within Tegucigalpa. The primary research methods employed during the second stage of the …

Prospects For Political Reform In China, Jody Lee Tomlin

USF Tampa Graduate Theses and Dissertations

This study is intended to analyze levels of institutional confidence in China. The purpose is to measure the relationship between changing political and cultural values with modernization and levels of institutional criticism. To analyze institutional criticism modernization and political culture theories are used. Using these theories together offers explanatory power as to what political and cultural values may change and why changes in confidence in governance may occur. These theories include socioeconomic, traditional, and political values to measure institutional confidence in 1990 and 2007. The examination of traditional versus modernization values imply that individuals possessing these opposing values display different …

High Stakes Play: Early Childhood Special Educators' Perspectives Of Play In Pre-Kindergarten Classrooms, Joanne Scandling Manwaring

USF Tampa Graduate Theses and Dissertations

This study examined Early Childhood Special Educators' perceptions of play as a developmentally appropriate practice in special education prekindergarten classrooms in one southeastern school district. Through purposeful sampling, eight prekindergarten special educators were identified because they held multiple teaching certifications and some held National Board certification. The participants had many years of experience in pre-kindergarten special education, and were professional development trainers, teacher mentors and or leaders in the prekindergarten special education community. These eight accomplished pre-kindergarten special education teachers were interviewed using an informal, semi-structured format about their beliefs concerning play, how they implement it in their classrooms as …

Accuracy Of Educator Nominations In Identifying Students With Elevated Levels Of Anxiety And Depression, Jennifer Cunningham

USF Tampa Graduate Theses and Dissertations

Internalizing disorders, specifically depression and anxiety, affect up to 18% and 33% of youth, respectively (Costello, Egger, & Angold, 2005b). Schools have become a major provider of mental health services to children, primarily in attempts to overcome barriers to receiving community services (Farmer, Burns, Philip, Angold, & Costello, 2003). As such, it is important that schools have effective mechanisms in place to accurately identify students who may be in need of such services. The current study examined the accuracy of one such method, educator nominations (including from both teachers and school-based mental health professionals) in identifying students who self-report elevated …

The Role Of Male Partners In Childbirth Decision Making: A Qualitative Exploration With First-Time Parenting Couples, Sharon Dejoy

USF Tampa Graduate Theses and Dissertations

Fathers' attendance at childbirth is almost universal in the United States, but few researchers have addressed the role that males play in childbirth decision making. The number of technological interventions available to birthing women is increasing, as is the utilization of those interventions. The degree to which women choose or agree to these interventions plays a major role in individual and societal health outcomes. Therefore, health care policy makers and educators must find ways to help childbearing couples navigate the complex maze of decisions related to childbirth. However, policies and programs to increase shared decision making may not function as …

Social Landscapes Of Transegalitarian Societies: An Analysis Of The Chipped Stone Artifact Assemblage From The Crystal River Site (8ci1), Citrus County, Florida, Richard William Estabrook

USF Tampa Graduate Theses and Dissertations

The research undertaken in this dissertation was designed to explore how the institutionalized social inequalities in prehistoric Woodland society are reflected in the differences in the procurement, in the life history, and the final discard locations of the flaked chert stone tools from the Crystal River site (8CI1). The Woodland period (1000 BC to AD 1000) was a time of both stability and change in Native American society. Many of the core institutions such as subsistence, hunting and ceramic technology, and residence remained relatively constant while religious and political institutions underwent dramatic changes. This study focuses on how these social …

Quasi 3-Dimensional Electrical Resistivity Mapping Of Air-Filled Karst Conduits And Policy Implications, Charles W. Mccrackin

USF Tampa Graduate Theses and Dissertations

This study assesses the capability and practical applications of quasi 3-Dimensional (3D) electrical resistivity surveying (ER) for mapping air-filled karst conduits. Vadose zone caves within the Brooksville Ridge of West Central Florida are relatively similar in architecture, with N-S elongation, and do not consist of an interconnected network of conduits. A high resolution quasi-3D ER survey was performed over two mapped cave systems on the Brooksville Ridge. The resultant survey verified the general effectiveness of quasi-3D ER in locating the two known near-surface cave features. Several other locations in the survey show similar or stronger resistivity anomalies trending in a …

The Holistic Complementary Structure Of Western Bio-Medicine And Traditional Healing And Achieving Complete Health, Candace Gail Oubre

USF Tampa Graduate Theses and Dissertations

Achieving complete health requires a deep understanding of complementary cultural competency sensitivity between physician and patient. This may include but is not limited to access to preventative health care resources, access to health educational resources and access to cultural healing resources, for example, shamans, Ayurvedic physicians, and herbal healers. Advocates of cultural competency emphasize great importance on knowledge of the patients' cultural background; however, the transcendence of this knowledge can be explained further through complementary cultural competency sensitivity. This is when the cultures of the physician and patient complement each other in terms of understanding what is in the patients' …

Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske

USF Tampa Graduate Theses and Dissertations

The contextual cueing effect was initially thought to be the product of memory guiding attention to the target location. However, the steep search slopes obtained in contextual cueing indicate an absence of attentional guidance. We hypothesized that crowding could be obscuring the presence of attentional guidance and investigated this possibility in 2 experiments. Crowding was manipulated by varying the density of items in the local target region in a contextual cueing task. We observed a significant reduction in search slopes between the novel and repeated conditions when crowding was reduced. Enhancing crowding eliminated the contextual cueing effect. These findings suggest …

Emotional Reactivity And Regulation In Current And Remitted Depression: An Event Related Potential Study, Lauren M. Bylsma

USF Tampa Graduate Theses and Dissertations

Major Depressive Disorder (MDD) is thought to be characterized by emotion regulation deficits, including decreased use of adaptive strategies such as reappraisal, but little is known about the exact nature of these deficits and whether or not they are specific to the depressed mood state. The late positive potential (LPP) is a sustained positive deflection of the event-related potential (ERP) associated with responding to emotionally-valenced stimuli, and reappraisal strategies have been found to reduce LPP magnitude in response to emotional stimuli in healthy individuals, but this effect has not been examined in MDD. This study utilized ERPs to examine emotional …

Characterization Of The Serologic Responses To Plasmodium Vivax Dbpii Variants Among Inhabitants Of Pursat Province, Cambodia, Samantha Jones Barnes

USF Tampa Graduate Theses and Dissertations

The Plasmodium vivax Duffy Binding Protein (DBP) is the ligand in the major pathway for P. vivax invasion of human reticulocytes, making it an appealing vaccine candidate. Region II of DBP (DBP-RII) is the minimal portion of the ligand that mediates recognition of the Duffy Antigen Receptor for Chemokines (DARC receptor) on the reticulocyte surface and constitutes the primary vaccine target. Analysis of natural variation in the coding sequences of DBP-RII revealed signature evidence for selective pressure driving variation in the residues of the putative receptor-binding site. We hypothesize that anti-DBP immunity in P. vivax infections is strain-specific and hindered …

Determination Of Ibuprofen Isotherm Using Supercritical Fluid Chromatography, Loi Ho

USF Tampa Graduate Theses and Dissertations

Chromatography is widely used to determine physiochemical properties data including adsorption isotherm. In the separation of enantiomers through sorptive processes, supercritical fluids allow efficient and green alternatives to liquid solvent based systems. The isotherm information is vital in the development of operating policies and design of preparative chromatographic or moving bed separation schemes. Determination of sorption isotherms from experimental chromatographic elution data is automated and compared with different chromatogram model. Procedures were developed and validated for separation of R- and S- ibuprofen with supercritical 〖CO〗_2 and ethanol mixture as the mobile phase over a chiral stationary phase. The isotherms for …

Discovery Of A Functional Ecdysone Response Element In Brugia Malayi, Tracy Enright

USF Tampa Graduate Theses and Dissertations

The aim of this study was to determine whether functional ecdysone response elements (EcREs) exist within the genome of Brugia malayi, a parasitic nematode that causes lymphatic filariasis. The hypothesis that EcREs exist in B. malayi stemmed from previous demonstration of a functional ecdysone response system in B. malayi (Tzertzinis et al., 2010). Real-time PCR (qPCR) experiments were conducted to measure gene expression levels for twelve genes proximal to five putative EcREs in 20-OH ecdysone treated and untreated B. malayi embryos. Seven genes showed consistent upregulation with 20-OH ecdysone treatment. Each of the five putative EcREs had at least one …

A Retrospective And Prospective Comparison Of Hungarian Children Who Have One Or Two Episodes Of Depression, Vanessa Panaite

USF Tampa Graduate Theses and Dissertations

Early onset depression is associated with high recurrence rates later in life. Recurrent depressive episodes during childhood may be particularly problematic, if additional episodes have a scarring effect that hinders healthy development. Distinguishing between first onsets and recurrences has been useful in understanding adult depression. This distinction has seldom been examined in pediatric depression, in part because it is difficult to enroll adequate samples of children with recurrent depression. We conducted archival analyses of carefully-diagnosed pediatric probands with depression first onset between ages of 4 and 12. Probands who reported one depressive episode (N = 435) were compared with probands …

Aging With Independence And Interaction: An Assisted Living Community, Steven J. Flositz

USF Tampa Graduate Theses and Dissertations

As the U.S. population gets older, there is an increased need for senior housing. However, elderly housing is currently associated with dependence and isolation. There is a great disconnect from the retired community with its surrounding context. Senior housing and nursing homes are becoming more similar to miniature hospitals rather than a residential type. This negative view of nursing homes is becoming clear to the general population. In fact, most seniors fear the idea of living within an aging complex. Also, people generally avoid these places, even while visiting family. Florida is on the frontline for the effects of the …

An Observation Of Immunological Effect, A Diet Enhanced With Spirulina And Treatment With Fractalkine In Models Of Parkinson's Disease, Mibel M. Pabón

USF Tampa Graduate Theses and Dissertations

In my dissertation research we used use human wild type α-synuclein gene expression using an adeno-associated viral vector (AAV9) that induced a slowly progressive loss of dopamine (DA) neurons in the Substantia nigra (SN) as one of our animal model of Parkinson’s disease (PD). It is our hypothesis that neuroinflammation predisposes the brain to susceptibility to neurodegenerative diseases. Thus we examined the progression of a PD lesion and examined the manipulations of the immune system to understand further the inflammatory role when we administered exogenous soluble fractalkine.

The specific etiology of neurodegeneration in PD is unknown, but the inflammatory mechanisms …

Historical Archaeology Of The Pine Level Site (8de14), Desoto County, Florida, Jana Futch

USF Tampa Graduate Theses and Dissertations

In 1866 the seat of Manatee County was moved to Pine Level, a newly-formed town in the wilderness of south Florida. By the 1880s, it contained stores, boardinghouses, churches, and government buildings. In 1887, Pine Level became DeSoto County’s first seat. However, when it lost county seat status to Arcadia only 18 months later, in 1888, Pine Level rapidly declined in population and importance, and eventually died out. The investigations of the Pine Level site detailed in this thesis were carried out as a public archaeology project, involving the DeSoto County Historical Society, University of South Florida, and the Florida …

Evaluation Of Preference For Exergames Among Elementary Students, Christie Ann Cacioppo

USF Tampa Graduate Theses and Dissertations

Obesity in children is a nationwide problem. Physical activity is one way to help children stay fit and prevent obesity. Unfortunately, access to technology involving sedentary behavior is easier than ever. Fortunately, for this generation of students there is a way to combine physical activity and technology through exergaming. In order to encourage students to participate in exergaming, the students should be able to play games they prefer. The purpose of this study was to apply a paired choice preference assessment, rank order card sort, and social validity surveys to determine the preference order of six exergames for six elementary …

Fundamental Transversals On The Complexes Of Polyhedra, Joy D'Andrea

USF Tampa Graduate Theses and Dissertations

We present a formal description of `Face Fundamental Transversals' on the faces of the Complexes of polyhedra (meaning threedimensional polytopes). A Complex of a polyhedron is the collection of the vertex points of the polyhedron, line segment edges and polygonal faces of the polyhedron. We will prove that for the faces of any 3-dimensional complex of a polyhedron under face adjacency relations, that a `Face Fundamental Transversal' exists, and it is a union of the connected orbits of faces that are intersected exactly once. While exploring the problem of finding a face fundamental transversal, we have found a partial result …

"Take Another Look At 'Em": Passing Performances Of Gender In The Junior-Freshman Weddings Of Florida State College For Women, 1909-1925, Sarah Lynne Jünke

USF Tampa Graduate Theses and Dissertations

Junior-freshmen weddings were all-female mock weddings that were performed as annual traditions on college campuses throughout the U.S. in the early part of the twentieth-century. In the weddings, college women played both the men's and women's roles, and were joined as husband and wife by their college administration. This thesis focuses on the junior-freshman weddings of Florida State College for Women during the years 1909-1925 and argues that the weddings expressed the conflicted cultural contexts that college women in the Progressive Era confronted, but that, significantly, this expression was done through passing performances of gender. The women's choice of passing …

Female Teachers As Sexual Predators: A Qualitative Study Of Grades 7-12 In The State Of Florida's Public Schools, Jayme Lynn Joslyn

USF Tampa Graduate Theses and Dissertations

This study's purpose was to discover commonalities and differences among female predators and Florida female teachers who are perceived and reported to harass students sexually. When perceived and reported female sexual harasser and student safety was researched, a breath of studies did not occur. When current studies were reviewed, teacher sexual harassment continued to occur. In this qualitative study, ten Florida public school female teachers who were perceived and reported to sexually harass students were randomly selected. Findings indicted that further research is still needed on female teachers who are perceived and reported to sexually harass students. When researching the …

Utilizing Probabilistic Reinforcement To Enhance Participation In Parent Training, Errity Jones

USF Tampa Graduate Theses and Dissertations

Parental participation in parent training programs is necessary for success in behavioral parent training. Prior literature has demonstrated probabilistic reinforcement as an effective intervention for improving a wide variety of behaviors. In the present study, a probabilistic reinforcement program (i.e., lottery) was implemented in order to evaluate its efficacy as part of a behavioral parent training program. The behaviors targeted for increase included attendance, participation, homework completion, and performing role-plays or completing in-class assignments for two 10 week Tools for Positive Behavior Change courses. Participants earned lottery tickets for each of the dependent measures, and drawings took place at the …

Perseverative Cognition, Cognitive Load, And Distraction In Recovery From Stress, Alvin B. Jin

USF Tampa Graduate Theses and Dissertations

Perseverative cognition is the repetitive cognitive representation of a stressor, which includes the concepts of worry and rumination. These thoughts delay post-stress cardiovascular recovery, which may lead to an increased risk for cardiovascular disease. This may be due to the negative emotional content of perseverative cognition or because it involves cognitive effort. The aim of this study was to identify the unique influences of negative emotional content and cognitive effort during recovery. Participants (N = 120) were given a demanding task purportedly as a measure of intelligence and then given false negative feedback. Immediately following, participants engaged in one of …

Modeling Endogenous Treatment Eects With Heterogeneity: A Bayesian Nonparametric Approach, Xuequn Hu

USF Tampa Graduate Theses and Dissertations

This dissertation explores the estimation of endogenous treatment effects in the presence of heterogeneous responses. A Bayesian Nonparametric approach is taken to model the heterogeneity in treatment effects. Specifically, I adopt the Dirichlet Process Mixture (DPM) model to capture the heterogeneity and show that DPM often outperforms Finite Mixture Model (FMM) in providing more flexible function forms and thus better model fit. Rather than fixing the number of components in a mixture model, DPM allows the data and prior knowledge to determine the number of components in the data, thus providing an automatic mechanism for model selection.

Two DPM models …

Exploring Instructional Strategies And Learning Goals In Undergraduate Leadership Education, Daniel Jenkins

USF Tampa Graduate Theses and Dissertations

Leadership education has been integral to the undergraduate curriculum since the early 1990's. Today, more than 1,000 colleges and universities in the United States offer undergraduate courses in leadership studies and many offer academic credit in the form of a bachelor's degree, academic minor, or certificate. Yet, little is known about those who teach leadership studies courses to undergraduates, the instructional strategies they employ, or the learning goals they set. The purpose of this study was to identify the instructional strategies that are most frequently used by instructors when they teach academic credit-bearing undergraduate leadership studies courses, identify signature pedagogies …

Oxygen Diffusion Characterization Of Frp Composites Used In Concrete Repair And Rehabilitation, Chandra K. Khoe

USF Tampa Graduate Theses and Dissertations

Many independent studies have conclusively demonstrated that fiber reinforced polymers (FRP) slow down chloride-induced corrosion of steel in concrete. The mechanism for this slow down is not well understood but it has been hypothesized that FRP serves as a barrier to the ingress of chloride, moisture, and oxygen that sustain electrochemical corrosion of steel.

This dissertation presents results from an experimental study that determined the oxygen permeation rates of materials used in infrastructure repair. In the study, the oxygen permeation constants for epoxy, carbon and glass fiber laminates, concrete, epoxy-concrete and FRP-concrete systems were determined and a method developed to …

Biodegradation Of Bisphenol-A And 17b-Estradiol In Soil Mesocosms Under Alternating Aerobic/Anoxic/Anaerobic Conditions, Won-Seok Kim

USF Tampa Graduate Theses and Dissertations

Soil-aquifer treatment (SAT) has been proposed as a method for reusing treated municipal wastewater. SAT is characterized by alternating cycles of aerobic and anaerobic conditions in the subsurface, in response to alternating cycles of flooding and drainage of a surface impoundment. It is not yet known how these alternating redox conditions affect the removal of potentially harmful endocrine-disrupting compounds (EDCs) from treated effluent.

The overall objective of my doctoral research is to determine the fate of EDCs in alternating aerobic/anoxic/anaerobic conditions under simulated SAT conditions. To assess the fate of EDCs in simulated SAT conditions, I first had to develop …
