However, there is limited research addressing whether schools are an appropriate setting and the intended as well as unintended effects of sharing this information with parents. Furthermore, there is yet to be conclusive evidence that shows that BMI screening in the school setting is an effective way to improve student BMI status. Therefore, the purpose of this research study was to explore the effects of BMI Health Report Card Letters among 6th grade students and …

Latent Newspaper Functions During The Impact Phase Of Hurricane Katrina, Christina A. Brown

USF Tampa Graduate Theses and Dissertations

Media is used by audiences for more than its simple role as information provider. Audiences have been found to use news providers output in a multitude of ways. It has been found that some audience members have used such output as a way to gain social capital that aids in the generation of feelings of social cohesion with their community. This has been found to be especially true during the impact phase of a natural disaster, such as a hurricane (Perez-Lugo, 2004). Unfortunately what news providers specifically articulate that might have this latent use by audiences has not been studied …

Gender And Internal Migration In Wuhan, Hubei Province, China: Rural Hometowns, Factory Work, And Urban Experiences, Milena Urszula Janiec-Grygo

USF Tampa Graduate Theses and Dissertations

This thesis focuses on gender and scale as key aspects of the rural-to-urban migration process in China. Its specific aim is to connect economic and social reasons for rural women's migration towards urban factory work. Contemporary large-scale migration studies show inconsistencies and contradictions concerning reasons for migration, especially as it relates to gender. Thus, migration research often emphasizes the positive social changes experienced by women workers, in effect signaling that the most important needs of women migrants can be satisfied without economic gains. In contrast, the proposed study seeks to show that social and economic reasons intertwine within women's experiences …

Phonological awareness development was measured using the Dynamic Indicators of Basic Early Literacy Skills First Sound …

Leading Change In Schools: Leadership Practices For A District Supported School-Based Reform Model, Monica C. Verra

USF Tampa Graduate Theses and Dissertations

The reauthorization of the Individual with Disabilities Education Act of 2004 strongly encourages the use of a response-to-intervention (RtI) model to reduce the number of students identified as learning disabled, to increase student achievement, and to close learning gaps between subgroups of students. RtI is based on the systematic assessment of students' responses to high-quality research-based instruction and interventions. The implementation of a research-based school-specific intervention model, such as RtI, may result in significant change for schools and districts.

The purpose of this study was to describe perceptions of the level of change the implementation of RtI represents in a …

Mathematics Education: The Voice Of African American And White Adolescents, Sharondrea R. King

USF Tampa Graduate Theses and Dissertations

Several studies have provided evidence regarding factors that contribute to the mathematics achievement gap between African American and White students. Byrnes (2003) found that 45%-50% of the difference in White and African American students' performance in mathematics was associated with socioeconomic status, exposure to learning opportunities, and motivational aspects of math while 4.5% was explained by ethnicity. The goal in this mixed method study was to examine the mathematics attitude of African American (n = 22) and White (n = 10) high school students and to allow students to voice what practices and supports they perceived enabled them to learn …

Tracing Anthropogenic Wastes: Detection Of Fluorescent Optical Brighteners In A Gradient Of Natural Organic Matter Fluorescence, Laura Kellie Dixon

USF Tampa Graduate Theses and Dissertations

A dual wavelength method was developed for the field detection of optical brighteners

(OBs), fluorescent laundry additives used as indicators of anthropogenic wastes. The

method was quantitative for OBs under variable levels of fluorescent colored dissolved

organic matter (CDOM). Based on excitation at 300-400 nm and 440 and 550 nm

emission, the method assumed a constant ratio of fluorescence due to CDOM alone, even

if absolute amplitude varied. Concentrations of OBs were computed as the difference

between the observed 440 nm emission and the expected CDOM fluorescence at 440 nm,

as extrapolated from the 550 nm fluorescence and established CDOM …

Effects Of Expectancies And Coping On Pain-Induced Motivation To Smoke, Joseph W. Ditre

USF Tampa Graduate Theses and Dissertations

The prevalence of tobacco smoking among persons with recurrent pain is approximately twice that observed in the general population. Smoking has been associated with the development and exacerbation of several chronically painful conditions. Conversely, there is both experimental and cross-sectional evidence that pain is a potent motivator of smoking. A recent study provided the first evidence that laboratory-induced pain could elicit increased craving and produce shorter latencies to smoke (Ditre & Brandon, 2008). To further elucidate interrelations between pain and smoking, and to identify potential targets for intervention, the current study tested whether several constructs derived from social-cognitive theory influence …

The Influence Of Perceived Social Support From Parents, Classmates, And Teachers On Early Adolescents’ Mental Health, Tiffany N. White

USF Tampa Graduate Theses and Dissertations

The present study examined the relationships among perceived social support, mental health, and achievement in early adolescents, via analysis of an archival data set consisting of 390 middle school students. Specifically of interest was how various sources of social support (i.e., parent, classmate, and teacher) independently and uniquely predicted pathology (i.e., internalizing and externalizing symptoms) and wellness (i.e., life satisfaction) in youth. This study also examined the role of gender in the relationship between social support and mental health outcomes in order to delineate the specific types of support most salient to boys versus girls. Finally, this study explored the …

The Development Of A Human Polyomavirus Quantitative Pcr Assay To Assess Viral Persistence, Water Quality, And Human Health Risks, Shannon M. Mcquaig

USF Tampa Graduate Theses and Dissertations

Microbial water quality is generally assessed using fecal indictor organisms; however host-specific microbial source tracking (MST) methodologies can be employed to differentiate sources of fecal pollution. The central goal of this research was to develop and validate a QPCR assay for the quantification of two human-specific polyomaviruses (HPyVs) in environmental water samples. These viruses are prevalent worldwide and produce lifelong, asymptomatic viruria in immunocompetent individuals.

A Taqman® quantitative PCR (QPCR) assay based on the conserved T-antigen of two HPyVs (JCV and BKV) was developed and optimized (Chapter 2). HPyVs were detected in a high proportion of human-associated waste samples (e.g. …

Shaping The Dream: A Survey Of Post-World War Ii St. Petersburg, 1946-1963, Jon L. Wilson

USF Tampa Graduate Theses and Dissertations

St. Petersburg stood on the cusp of great change in 1946. Returning veterans sought jobs and housing, and St. Petersburg experienced its first major growth era since the real estate boom of the 1920s. The decade of the 1950s saw the city's population leap from 96,738 to 181,298, an 87 percent increase driven by boosters and national publicity about the city's leisurely ambience. Tract houses replaced remaining pockets of pasture and pine trees as subdivisions sprawled toward the city limits and beyond. On fertile truck-farming acreage called Goose Pond, developers built Central Plaza, a shopping center positioned to drain business …

Additive Latent Variable (Alv) Modeling: Assessing Variation In Intervention Impact In Randomized Field Trials, Peter Ayo Toyinbo

USF Tampa Graduate Theses and Dissertations

In order to personalize or tailor treatments to maximize impact among different

subgroups, there is need to model not only the main effects of intervention but also the variation

in intervention impact by baseline individual level risk characteristics. To this end a suitable

statistical model will allow researchers to answer a major research question: who benefits or is

harmed by this intervention program? Commonly in social and psychological research, the

baseline risk may be unobservable and have to be estimated from observed indicators that are

measured with errors; also it may have nonlinear relationship with the outcome. Most of the …

Sugar Ethanol In Florida: Economic, Agricultural, And Environmental Aspects, Joshua F. Berger

USF Tampa Graduate Theses and Dissertations

Ethanol production has been widely perceived as a solution to the global energy crisis, with the added benefit of reinvigorating declining agricultural economies. Moves towards dedicating crop production to ethanol however have raised a number of concerns related to its economic and environmental consequences. Missing from this debate is a consideration of the ways in which sugar can be used as a feedstock for ethanol, an issue that is especially pertinent within the state of Florida. The national commitment and scale of corn ethanol production in the U.S. has largely meant a lack of focus on other feedstocks which could …

Cultural Competence In Health Care: A Client-Based Perspective, Karon L. Phillips

USF Tampa Graduate Theses and Dissertations

In response to the presence of health disparities among a diverse population of older adults, creating culturally competent health care services has emerged as a possible method to help reduce and eventually eliminate inequalities in health care. However, little information exists concerning the effectiveness of cultural competence, and even less is known about how culturally competent clients perceive their providers to be. This dissertation examined a number of indicators related to cultural competence, including the predictors of client-provider racial/ethnic concordance, client perceptions of the interpersonal sensitivity of their health care providers, and the overall satisfaction with care reported by older …

Living With Sugar: Socioeconomic Status And Cultural Beliefs About Type 2 Diabetes Among Afro-Caribbean Women, Chrystal A.S Smith

USF Tampa Graduate Theses and Dissertations

In the U.S., individuals of Afro-Caribbean and Latino descent are two to three times more likely to develop type 2 diabetes than non-Hispanic whites. Caribbean and Latin America migrants, particularly minority women bear a disproportionate burden of type 2 diabetes and its risk factors. The purpose of this research is to investigate if Afro-Caribbean women share a cultural belief model about type 2 diabetes and how this belief model, along with structural barriers to health care, influence disease risk and management.

A sample of 40 women, primarily Jamaican and Trinidadian, 35 to 90 years of age previously diagnosed with type …

Evaluation Of A Self-Monitoring Program To Increase Treatment Integrity Of Behavior Intervention Plans, Lela E. Taylor

USF Tampa Graduate Theses and Dissertations

The growing number of school-aged children displaying challenging behavior has increased the need for effective interventions. School-based consultants (SBC) report using behavioral consultation to assist teachers in designing behavior intervention plans (BIP) that help students engage in appropriate behavior in the classroom. Research indicates that direct training methods increase teacher's implementation of the BIP. One commonly used direct training method, performance feedback (PF), is used to assess teachers' treatment integrity. Research also indicates that checklists (non-direct measures) are more cost efficient methods. The purpose of this paper was to evaluate a direct training method used to train teachers to self-monitor …

The addition of outpatient drugs to the Medicare programs reflects Congress’ recognition of the fundamental change in recent years in how medical care is delivered in the U.S. It recognizes the vital role of prescription drugs in the health care delivery system and the need to modernize Medicare to assure their availability to Medicare beneficiaries. The Medicare Prescription Drug Improvement and Modernization Act of 2003 (MMA) created the Medicare drug benefit and specified a standard plan. The law also enables …

Molecular Intervention In Mouse Models Of Amyotrophic Lateral Sclerosis And Alzheimer’S Disease – Neuropathology And Behavior, Steven Prescott Bennett

USF Tampa Graduate Theses and Dissertations

Neurodegeneration describes the progressive loss of structure and function of neurons, leading ultimately to cell and organism death. Although the initiating factors of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, Huntington’s, and Amyotrophic Lateral Sclerosis may be different, they share common pathophysiologies. Proteinopathies, as these diseases are now termed, are characterized by atypical deposits of proteins, often due to misfolding. Associated with these deposits are dysfunctional mitochondria, oxidative stress, disrupted axonal transport, inflammation, and apoptotic cell death. If this occurs in motor neurons, as in ALS, ataxia precedes death with little or no change in cognition. On the other hand, if …

An Exploratory Analysis Of The Ecological Validity Of A Performance-Based Assessment Of Attention, Eun- Yeop Lee

USF Tampa Graduate Theses and Dissertations

Executive functions impact everyday functioning. An individual’s ability to adapt

to and navigate their physical and social environments is largely determined by the ability

to organize oneself, to plan and to coordinate activities. Despite the wide variety of

cognitive tests that assess various aspects of executive function, there has been little work

to validate the use of these measures in predicting real world functioning (Sbordone,

Seyranian, & Ruff, 2000), particularly in children where characterization of executive

function is less specified. Evaluating the ecological validity of neuropsychological tests

has become an increasingly important topic over the past decade (Chaytor & Schmitter- …

Co-Transcriptional Splicing And Functional Role Of Pkcβ In Insulin-Sensitive L6 Skeletal Muscle Cells And 3t3-L1 Adipocytes, Eden Kleiman

USF Tampa Graduate Theses and Dissertations

PKC

βII is alternatively spliced during acute insulin stimulation in L6 skeletal

muscle cells. This PKC

βII isoform is critical in propagating GLUT4 translocation.

PKC

β protein and promoter dysfunction correlate with human insulin resistance. TZD

treatment ameliorates whole-body insulin-resistance. Its primary target is adipocyte

PPAR

γ, which it activates upon binding. This causes both altered circulating serum FFA

concentrations and adipokine secretion profile. How TZDs affect the intracellular

signaling of skeletal muscle cells is unknown. RT-PCR and Western blot analysis

showed that TZDs elevated PKC

βII by a process that involves co-transcriptional splicing.

PGC1

α overexpression most closely resembled …
