The Effects Of Learning-Styles Information On The Achievement Of Community College Developmental Math Students, Kevin A. Hoeffner

USF Tampa Graduate Theses and Dissertations

Four out of five Americans will require some postsecondary education. Therefore, a majority of population will return to a community college for retraining and personal growth (McCabe, 2003). Since the turn of this century, many studies have been conducted to examine the success and challenges of the relatively new community college system. One of the most significant challenges is the large percentage of the U.S. population requiring remedial coursework. Fifty-five percent of students entering Florida's postsecondary system require remediation. Of this large remedial population, only 51% will complete their preparatory classes. Students who do complete classes take an average of …

Impact Of Globalization On Socio-Economic And Political Development Of The Central Asian Countries, Karina Orozalieva

USF Tampa Graduate Theses and Dissertations

The main objective of this thesis is to understand the economic, social and political impacts of globalization on the Kyrgyzstan, Kazakhstan and Central Asian countries in general. The empirical studies based on panel data analyses and the case study on Kyrgyzstan demonstrate that the socio-economic effect of globalization on development of these countries is twofold. On the one hand benefits produced by globalization such as migration and remittances can be useful for economic development in the short run. They take a role of a "shock absorber" of the challenges that are associated with transition to a free market economy. On …

Answer Distortion On The Epworth Sleepiness Scale During The Commercial Driver Medical Examination, Keith E. Proctor

USF Tampa Graduate Theses and Dissertations

Commercial vehicle drivers are required to maintain Department Of Transportation medical certification which entails a Commercial Driver Medical Examination (CDME) and optimally leads to a two-year certification. The examination must be performed by a licensed "medical examiner" administered by a variety of health care providers including physicians, advanced registered nurse practitioners, physician assistants and doctors of chiropractic. Unfavorable findings in the examination can yield either a shortened medical certification period or denial of certification. Sleep disorders including sleep apnea are assessed by a single question located in the health history portion of the CDME form which is filled-out by the …

Lived Experience: Near-Fatal Adolescent Suicide Attempt, Phyllis Ann Dougherty

USF Tampa Graduate Theses and Dissertations

Adolescent suicide has become a national health crisis. Suicide now ranks as a leading cause of adolescent death in the U.S. In response to this, the National Strategy for Suicide Prevention (2001b) recommended the promotion and support of research into suicide and prevention, particularly high-risk groups such as adolescents. However, due to concerns for safety and liability, there have been few studies of highly suicidal individuals, specifically adolescents. Leading suicidologists have agreed that studying the qualities of the near-fatal suicide attempt can most resemble the completed suicide.

This case study explored the phenomenon of the near-fatal suicide attempt through the …

Low Documented Risk Cesarean Sections And Late-Preterm Births: The Florida Experience, Heather Breeze Clayton

USF Tampa Graduate Theses and Dissertations

There are increasing concerns about the excessive use of cesarean delivery in the United States, as cesarean deliveries have been associated with adverse maternal and infant health outcomes. Currently, the cesarean section (C/S) rate for Florida is the second highest in the nation. Furthermore, preliminary reports from the Florida Department of Health (FDOH) have implicated the increasing rate of cesarean delivery to an increase in the rate of late preterm births (PTB) in Florida (births at 34 to 36 weeks gestational age). Information on the impact of late PTB associated with cesarean delivery on the rate of maternal and infant …

Implicit Affect And Alcohol Outcome Expectancies, John M. Ray

USF Tampa Graduate Theses and Dissertations

Expectancy theory provides a useful framework within which to examine the link between cognitive representations of anticipated alcohol related outcomes and affective processes that ought to shape behavior at the level of implicit, or automatic, processing. The role of affect in alcohol expectancies is an important one as it reflects the approach-avoid contingency associated with reward learning presumed to underlie addictive processes. This study examined the relationship between affect and expectancy operation by using suboptimally presented alcohol related cues to prime affectively congruent evaluations of otherwise unrelated targets. Hypotheses predicted that drinkers who reported higher positive and arousing expectancies for …

A Study Of Selected Teachers‘ Perceptions Of Grade Retention In A Florida School District, Julius L. Wynn

USF Tampa Graduate Theses and Dissertations

This study examined and analyzed selected middle school teachers' perceptions of grade retention, and informed teachers about current and past research on grade retention. Through analysis of teacher interviews and using a Likert scale instrument, responses indicated that teachers continue to support and to use retention when students do not master required objectives for promotion. Because of the new Florida retention policy and the No Child Left Behind policy, it was critical to measure teachers' levels of understanding and perceptions of grade retention.

Their perceptions gave insight into their thoughts and beliefs about the practice. Survey responses of 326 teachers …

Bird Communities Of Isolated Cypress Wetlands Along An Urban Gradient In Hillsborough County, Florida, Nathaniel L. Goddard

USF Tampa Graduate Theses and Dissertations

Migratory bird communities are sensitive to landscape alteration. Urban development significantly impacts bird communities on breeding grounds, as well as en-route during migration. One current theory is that Neotropical migratory birds are not limited by breeding or wintering habitat constraints but by food and habitat availability along major migration routes. The eastern flyway is the route taken by neotropical land-birds through eastern North America that follows coastal areas denoted by intense urban development. Coastal areas funnel birds to major departure points along the northern coast of the Gulf of Mexico and the western coast of Florida.

Birds were monitored for …

Characterization Of Cannabinoid Receptor 2 Transcript Expression In B Cells, Tracy Sherwood

USF Tampa Graduate Theses and Dissertations

Cannabinoids and cannabinoid receptors have been shown to play important roles in immune regulation particularly as modulators of anti-inflammatory cytokines and antibody production. The predominant cannabinoid receptor involved in this immune regulation is cannabinoid receptor 2 (CB₂), which is robustly expressed in B cells. Utilizing a combination of bioinformatics, 5' RACE, real time RT-qPCR, and reporter assays, we showed that human B cells from peripheral blood mononuclear cells (PBMC) expressed one CB2 transcript while mouse B cells from spleen express three CB₂ transcripts. Alignment of the sequenced B cell RACE products to either the mouse or human …

School Psychologists Involvement And Perceived Preparedness In The Provision Of Suicide-Related Services: A Comparison Of Practitioners Serving Different School Levels, Jennifer M. Cunningham

USF Tampa Graduate Theses and Dissertations

While the manifestation of suicidal thoughts and/or behavior is more common among adolescents, children are capable of, and do experience, suicidal ideation as well as demonstrate suicidal behaviors. Suicide is the sixth leading cause of death among children aged 5-14 years (Center for Disease Control [CDC], 2008). However, children may not always be referred or brought to the attention of the school psychologist, as their threats may be considered immature and unfounded. The purpose of this study is to provide data that clarifies the need for the provision of suicide-related services for children in elementary school. An archival dataset of …

Manifestations Of Hidden Curriculum In A Community College Online Opticianry Program: An Ecological Approach, Barry Hubbard

USF Tampa Graduate Theses and Dissertations

Understanding the influential factors at work within an online learning environment is a growing area of interest. Hidden or implicit expectations, skill sets, knowledge, and social process can help or hinder student achievement, belief systems, and persistence. This qualitative study investigated how hidden curricular issues transpired in an online learning environment's institutional and organization systems using an ecological paradigm. A phenomenological approach rooted in a case study context was used to explore the experiences and perceptions of a group of students, faculty, and administrators involved with an online academic program (opticianry) at a community college. Interviews, non-participant observation, and a …

An Interpretive Policy Analysis Of Bullying Law And The Development Of Bullying Policy In A Central Florida School District, Scott D. Richman

USF Tampa Graduate Theses and Dissertations

Bullying has been an issue in schools and became a major concern for school leaders over the past two decades. Olweus (1993) defined three characteristics of bullying behavior: intent to harm another, repeated offenses, and a perceived or real power imbalance. This study examined the law's provisions concerning bullying in schools; specifically examining the Florida Jeffrey Johnston Stand Up for All Student Act (2008), and the required policy implemented in Hillsborough County Public Schools (HCPS). Discourse theory framed the study, as defined by Habermas (1996) and the derivative Interpretive Policy Analysis was used to analyze the district policy, as defined …

Exploring Colorectal Cancer Diagnosis Disclosure To First-Degree Relatives: An African American Family Case Series, Kamilah B. Thomas

USF Tampa Graduate Theses and Dissertations

Colorectal cancer (CRC) is the second leading cancer killer in the United States and the third most common cancer in African American men and women. Though the overall death rates have declined, this reduction in mortality is smaller for African Americans than for Whites. Factors that are protective against colorectal cancer include occupational or recreational physical activity, a diet high in fruits and vegetables, and colorectal cancer screening with removal of polyps (polypectomy) before they progress to cancer. Compliance with CRC screening recommendations requires people to know if a first-degree relative (parent, sibling, and child) or second-degree relative (aunt, uncle, …

Depositional Dynamics In Seagrass Systems Of Tampa Bay, Fl: Influence Of Hydrodynamic Regime And Vegetation Density On Ecosystem Function, Alison Cheryl Meyers

USF Tampa Graduate Theses and Dissertations

Many coastal ecosystems around the world are dominated by submerged aquatic vegetation (SAV) habitats. These SAV habitats are known to provide many highly valuable ecosystem services such as habitat for commercial important species and increased water clarity. Water flow is an environmental variable which can have measurable effects on the ecosystem services provided by SAV, but is often not considered in studies assessing these services. This dissertation sought to investigate the links between SAV, primarily seagrasses, and hydrodynamics, paying special attention to the effects on sediments and fauna. Three main areas are discussed: (1) the effects of SAV on flow, …

Surface-Bonded Sol-Gel Sorbents For On-Line Hyphenation Of Capillary Microextraction With High-Performance Liquid Chromatography, Scott S. Segro

USF Tampa Graduate Theses and Dissertations

High-performance liquid chromatography (HPLC) is the most widely used analysis technique. However, its sensitivity is limited. Sample preconcentration methods, such as fiber-based solid-phase microextraction (SPME) and in-tube SPME (capillary microextraction) offer improved detection limits. It is, however, difficult to couple fiber SPME on-line with HPLC due to the need for complicated desorption devices. Such coupling is further complicated due to the limited solvent stability of the extracting phase both in the fiber and in-tube formats of SPME. In this research, surface-bonded sol-gel sorbents were developed to provide the solvent stability required for effective on-line hyphenation of capillary microextraction (CME) with …

A Comparative Study Of The Plants Used For Medicinal Purposes By The Creek And Seminoles Tribes, Kimberly Hutton

USF Tampa Graduate Theses and Dissertations

Previous studies in Native American ethnobotany on the shared use of medicinal and cultural plants between communities fail to clearly reveal if these shared uses are part of changing culture or remain a stabilizing connection between old and new tribes. During the late 1700's to early 1800's, various factions of the Creek tribes of Georgia migrated into Florida, forming a new tribe called the Seminoles. This event provides the unique opportunity to study the changing cultural and medicinal uses of plants by a new tribe in a new geographic location, revealing if cultural purposes were passed from one group to …

Differentiation Of Labor-Related Activity By Means Of Musculoskeletal Markers, Annette Doying

USF Tampa Graduate Theses and Dissertations

This study tests whether musculoskeletal markers are attributable to occupational categories. It is hypothesized that individuals over the age of 30 years with a lifetime occupation as a laborer will demonstrate a significantly different pattern of activity markers from individuals in the white collar classifications. A sample of n=69 from the Maxwell Museum's Documented Skeletal Collection are investigated.

Upper and lower extremities were scored for MSM type (robusticity, stress lesions, and ossification exostoses) and severity (grades 0 - 3) following Hawkey and Merbs (1995) visual reference system. To evaluate methodological approaches to MSM scoring, ossification exostoses and stress lesions were …

Mercury In The Environment: Field Studies From Tampa, Bolivia, And Guyana, Joniqua A'Ja Howard

USF Tampa Graduate Theses and Dissertations

Tampa (US), Guyana (SA), and Bolivia (SA), are geographically, socially, economically, and politically unique which make them ideal sites to study issues of mercury and sustainability. Mercury’s innate ability to bioaccumulate and biomagnify in aquatic and terrestrial ecosystems poses a severe threat to both human and environmental health. The most vulnerable populations affected by mercury consumption include coastal communities, children, women of child-bearing age, the indigenous poor and persons with high environmental/occupational exposure factors. Communities in the regions of Florida, Bolivia, and Guyana whose diets are high in fish and are environmentally/occupationally exposed to mercury may be at a higher …

Technology scaling to the nanometer levels has paved the way to realize multi-dimensional applications in a single product by increasing the density of the electronic devices on integrated chips. This has naturally attracted a wide variety of industries like medicine, communication, automobile, defense and even house-hold appliance, to use high speed multi-functional computing machines. Apart from the advantages of these nano-domain computing devices, their usage in safety-centric applications like implantable biomedical chips and automobile safety has immensely increased the need for comprehensive error analysis to enhance their reliability. Moreover, these nano-electronic devices have increased propensity to transient errors due to …

Gatekeeping And Citizen Journalism: A Qualitative Examination Of Participatory Newsgathering, Amani Channel

USF Tampa Graduate Theses and Dissertations

For nearly sixty years, scholars have studied how information is selected, vetted, and shared by news organizations. The process, known as gatekeeping, is an enduring mass communications theory that describes the process by which news is gathered and filtered to audiences. It has been suggested, however, that in the wake of online communications the traditional function of media gatekeeping is changing.

The infusion of citizen-gathered media into news programming is resulting in what some call a paradigm shift. As mainstream news outlets adopt and encourage public participation, it is important that researchers have a greater understanding of the theoretical implications …

Passive Acoustic Studies Of Estuarine Fish Populations Of Southwest Florida, James Vincent Locascio

USF Tampa Graduate Theses and Dissertations

Recordings of fish sound production were made in Charlotte Harbor, Florida using Long Term Acoustic Recording Systems (LARS) programmed to record 10 seconds of sound every 10 minutes. Results demonstrated a strong circadian pattern in fish sound production that occurred within a few hours of dusk each evening. Sound production lasted on average 8.7 hrs each evening during the peak spawning season. LARS were deployed when Hurricane Charley crossed Charlotte Harbor in August, 2004. The hurricane did not inhibit nightly chorusing events of spawning fish. Rather, sound levels produced by spawning fish on the night of and 3 days after …

The Fanconi Anemia (Fa)/Brca Dna Damage Repair Pathway Is Regulated By Nf-Κb And Mediates Drug Resistance In Multiple Myeloma, Danielle N. Yarde

USF Tampa Graduate Theses and Dissertations

The Fanconi Anemia (FA)/BRCA DNA damage repair pathway plays a critical role in the cellular response to stress induced by DNA alkylating agents and greatly influences drug response in cancer treatment. We recently reported that FA/BRCA DNA damage repair pathway genes are overexpressed and causative for resistance in multiple myeloma (MM) cell lines selected for resistance to melphalan. We hypothesized that the FA/BRCA DNA damage repair pathway mediates response and resistance to chemotherapeutic agents used to treat multiple myeloma and other cancers, and targeting this pathway is vital to overcoming drug resistance. In this dissertation, we show that FA/BRCA pathway …

Predicting Fear Of Recurrence And Protective Health Behaviors Using Protection Motivation Theory, Heather L. Mcginty

USF Tampa Graduate Theses and Dissertations

Prior research suggests that fear of cancer recurrence is very common among cancer survivors. This study examined the extent to which Protection Motivation Theory variables of threat appraisal and coping appraisal accounted for differences in fear of recurrence and performance of health behaviors in cancer patients who recently completed treatment. It was hypothesized that greater fear of recurrence would be related to a combination of high threat appraisal and low coping appraisal. Also, it was hypothesized that higher rates of health behaviors would be related to higher threat appraisals for cancer recurrence and higher coping appraisals for reducing risk of …

Filtration Efficiency Of Surgical Masks, Erin Sanchez

USF Tampa Graduate Theses and Dissertations

Surgical masks are intended to be used to prevent transmission of disease from a health care worker to a patient. Often times, they are relied upon by health care workers for their own protection. In light of recent developments regarding preparation for health care worker response to global infectious diseases such as H1N1 Influenza, health care workers may experience a false sense of security when wearing surgical masks. The goal of this study was to evaluate the filtration efficiency of a double strap tie-on surgical mask. The manufacturer asserts a >95% efficiency with a 0.1 um challenge aerosol under FDA …

Principal Investigator And Department Administrator Perceptions Of Services Provided By Offices Of Research Administration At Research Universities, Kimberley W. Cole

USF Tampa Graduate Theses and Dissertations

The purpose of this research study was to determine what service attributes were perceived as important factors for a successful Office of Research Administration (ORA) to provide to principal investigators and department administrators. Initially established more than 50 years ago, The Office of Research Administration (ORA) has evolved into an integral component for the fiscal sustainability of many institutions of higher education. Existing performance metrics based on financial measures do not sufficiently capture the quality of the level of service demands placed on the ORA by the two internal user groups. The conceptual basis of the Balanced Scorecard modified for …

Priming Expectancies: Effects On Neurophysiological Indices Of Expectancy Violations And Drinking Behavior, Tyler Brumback

USF Tampa Graduate Theses and Dissertations

Investigations of the anticipated effects of alcohol indicate that cognitive frameworks are highly correlated with drinking and other variables associated with alcohol use, explaining up to 50% of the variance in drinking outcomes (Goldman, Darkes, & Del Boca, 1999; Goldman, 2002; Goldman et al., 2006; Goldman, Reich, & Darkes, 2006). Furthermore, alcohol expectancies appear to mediate the relationship between a variety of risk factors, such as sensation seeking, and alcohol outcomes (Darkes, Greenbaum, & Goldman, 2004). The current study examined the relationship of these cognitive networks with a physiological index of expectancy violation

Participants were presented with statements reflecting a …

Assessing The Effectiveness Of The Roaring Branch Bmp Retrofit Using Macroinvertebrate Bioassessment, James L. Banning

USF Tampa Graduate Theses and Dissertations

Using benthic macroinvertebrates to measure stream health has been widely used and accepted around the world. Macroinvertebrates are resident monitors of chronic impairment in a stream since they are relatively sessile and most commonly respond to disturbance by drift but can recolonize a restored stream reach very quickly. This study tested the effectiveness of macroinvertebrate metrics developed through the Rapid Bioassessment Protocol (RBP) to detect changes in stream integrity as the result of placement of a best management practice (BMP), installed on a tributary of Roaring Branch, located in Columbus, Georgia. The BMP was designed to attenuate flow to reduce …

Where Christ Dies Daily: Performances Of Faith At Orlando‘S Holy Land Experience, Sara B. Dykins Callahan

USF Tampa Graduate Theses and Dissertations

This manuscript focuses on performances of place and faith inside the Holy Land Experience (HLE), an edutainment complex nestled in the fantasy nexus of Orlando, Florida. A self-proclaimed living-history museum, the HLE includes animatronic Bible characters and musical dramas. The HLE enacts and embodies evangelical narratives of Christianity and Christian faith, and visitors to the park are asked to join the performances, blurring the distinctions between spectators and professional actors. I argue that visitors' performances of faith invest the space of the HLE with sacredness, while the location and design of the HLE infuses the space with elements of the …

Looking Good And Taking Care: Consumer Culture, Identity, And Poor, Minority, Urban Tweens, Elizabeth Edgecomb

USF Tampa Graduate Theses and Dissertations

Looking Good and Taking Care: Consumer Culture, Identity, and Poor, Minority, Urban Tweens is an ethnographic examination of how poor, minority, urban tweens (age 7-14) use consumer culture to create and perform their personal and social identities. Although portrayed in mass media as selfish and hedonistic, this work finds tweens creating profoundly social, giving, and caring identities and relationships through consumption. Their use of consumer culture is also a form of political resistance that subverts their place in the age, class, and race hierarchy. These tweens use “looking good” (attention to grooming, style, and behaving respectably), and not name brand …
