Supporting Speech-Language Pathologist Evidence-Based Practice Use: A Mixed-Methods Study In Skilled Nursing Facilities Within The Promoting Action On Research Implementation In Health Services Framework, Natalie Franko Douglas

USF Tampa Graduate Theses and Dissertations

As the management of dementia is a significant public health concern, efforts to increase access to effective treatments to a greater number of residents with dementia in skilled nursing facilities (SNFs) are warranted. The treatment addressed in this study, non-electronic external memory aids, is an evidence-based practice that has been found to increase positive communicative interactions and decrease negative behavioral problems of residents with dementia in SNFs.

Although use of memory aids is recommended, there are significant barriers such as lack of time and resources that inhibit the use of effective treatments in typical clinical settings. To address such barriers …

Relationship Between Dysphoric Moods, Risk-Taking Behaviors, And Toxoplasma Gondii Antibody Titers In Female Veterans, Allyson Radford Duffy

USF Tampa Graduate Theses and Dissertations

The number of female veterans is increasing daily. Previous research conducted on veterans has focused primarily on males or with small samples of females. Depression and suicidality are becoming increasingly evident in returning veterans. Toxoplasma gondii is an intracellular parasite that is common in the Middle East and has been reported to cause changes in personality and behavior.

The purpose of the current study was to examine relationships between T. gondii antibody titer and socioeconomic variables, dysphoric moods, and risk-taking behaviors in a sample of 70 female veterans. Blood samples were collected and analyzed for T. gondii antibody titer and …

Accidental Detention: A Threat To The Legitimacy Of Venezuelan Democracy, Mabel Gabriela Durán-Sánchez

USF Tampa Graduate Theses and Dissertations

The main argument of this thesis is that the penitentiary crisis in Venezuela is brought about an inept criminal justice system whose functioning (or lack thereof) further exacerbates overcrowding in penitentiary facilities as well as violates the most basic human rights. More elaborately, I argue that the unintentional (mis)use of pre-trial preventive detention, one of the consequences of the inept criminal justice system, further exacerbates the overcrowding in prisons and creates serious human rights implications. The purpose of this study is to establish a connection between the penitentiary crisis in Venezuela, with a focus on pre-trial preventive detention, and the …

Social Studies Teachers In An Evaluative Role: The Peer Evaluator Experience In The Accountability Era, Martha Barnes Ford

USF Tampa Graduate Theses and Dissertations

As the evaluation of teachers becomes prominent in the current climate of educational reform, the details of teacher evaluation systems become important. The goal of the research was to gain perspective about a little-studied group key in education reform efforts to improve teacher evaluation--the peer evaluator. Teachers serving as peer evaluators were interviewed to reveal their perceived lived experiences before undertaking the role, benefits and challenges they perceived during the role, and their perception of how the experience will impact their future as educators. Extensive profiles of three peer evaluators were crafted based on in-depth interviews. The themes revealed from …

Exploring The Motives, Perceptions And Constructed Identities Of The Facilitators For One Regional Council Of A Positive Youth Development Program: Girls On The Run, Ashley Ann Gallentine

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to explore the coaches' perceptions, motives and constructed identities by participating in a regional physical activity-based positive youth development program. There is growing evidence that suggests the success of positive youth development (PYD) programs depend on the environment that is created by caring adult mentors. These coaches are the delivery vehicles for these programs and play an essential role in the development of participating youth. As a result, the characteristics these coaches possess are critical to the success of the PYD implementation. Based on the application of anthropological methods and theory, this study seeks …

Unbearable Weight, Unbearable Witness: The (Im)Possibility Of Witnessing Eating Disorders In Cyberspace, Kristen Nicole Gay

USF Tampa Graduate Theses and Dissertations

This thesis argues that the recent erasure of digital pro-anorexia ("pro-ana") narratives by websites such as Tumblr, Pinterest, and Instagram represents an attempt to silence female self-starvers and reify the authority of medical associations to speak for female bodies. I draw parallels between these attempts and Gayatri Chakravorty Spivak's theory of epistemic violence, since the experiences of women are effectively discredited, through metaphors that render the thin body dangerous, to shore up professional medical authority. As an attempt to privilege the experiences of the self-starvers, I analyze one Tumblr blog with eating disorder content to listen to the letters users …

How Does A Principal Use Intention And Strategy In The Enactment Of Advocacy Leadership, Lisa Marie Grant

USF Tampa Graduate Theses and Dissertations

District and school leadership are essential to the success of our students and our schools. While extensive conceptual literature describes leadership characteristics, there are few empirical studies that address the daily reality of schools. In addition, additional research is needed describing how principals maneuver within the context of schools and school districts. This phenomenological study explored how one elementary school principal understands and enacts leadership and to what extent she employs intentional strategies to facilitate change. The purpose of the study was to offer a rich profile of one elementary school principal's practice to understand how a principal constructs meaning, …

Multiple Calibrations In Integrative Data Analysis: A Simulation Study And Application To Multidimensional Family Therapy, Kristin Wynn Hall

USF Tampa Graduate Theses and Dissertations

A recent advancement in statistical methodology, Integrative Data Analyses (IDA Curran & Hussong, 2009) has led researchers to employ a calibration technique as to not violate an independence assumption. This technique uses a randomly selected, simplified correlational structured subset, or calibration, of a whole data set in a preliminary stage of analysis. However, a single calibration estimator suffers from instability, low precision and loss of power. To overcome this limitation, a multiple calibration (MC; Greenbaum et al., 2013; Wang et al., 2013) approach has been developed to produce better estimators, while still removing a level of dependency in the data …

Circulating Ceramics In The Eighteenth Century Colonial Circum-Caribbean: Towards An Archaeological Model For Inter-Site Comparison, Daniel B. Hughes

USF Tampa Graduate Theses and Dissertations

In the Caribbean, the eighteenth century symbolized a period of shifting powers in the region. Spain abandoned control of many of the smaller islands in the Caribbean, which were quickly taken over and subsequently controlled by the three major European competitors: England, France, and the Netherlands. These islands would be traded as prizes during various European conflicts that would always spread into the region. Unfortunately, most of the archaeological work that has occurred within the Caribbean has tended to largely focus on the micro-scale analysis. While development of a macro-scale analysis to assist an understanding of the past in the …

An Acoustic-Based Microfluidic Platform For Active Separation And Mixing, Myeong Chan Jo

USF Tampa Graduate Theses and Dissertations

Particle separation is of great interest to many biological and biomedical applications. Flow-based methods have been used to sort particles and cells. However, the main challenge with flow based particle separation systems is the need for a sheath flow for successful operation. Existence of the sheath liquid dilutes the analyte, necessitates precise flow control between sample and sheath flow, requires a complicated design to create sheath flow and separation efficiency depends on the sheath liquid composition. In addition, current gold standard active separation techniques are only capable of separation based on particle size; hence, separation cannot be achieved for same-size …

Does The Use Of Personally Relevant Stimuli In Semantic Complexity Training Facilitate Improved Functional Communication Performance Compared To Non-Personally Relevant Stimulus Items Among Adults With Chronic Aphasia?, Stephanie Karidas

USF Tampa Graduate Theses and Dissertations

This study investigated the influence of semantic complexity treatment in individuals with fluent aphasia on discourse performance. Semantic treatment is an effective way to improve semantically based word retrieval problems in aphasia. Treatment focused on the semantic application of the Complexity Account of Treatment Efficacy (CATE) (Thompson, Shapiro, Kiran, & Sobecks, 2003) promotes training of complex items resulting in generalization to less complex, untrained items. In addition, research has shown that the personal relevance of treatment material can increase treatment efficacy. This study investigated the effect of semantic treatment of atypical personally relevant items among individuals with aphasia on discourse …

The Psychophysiology Of Novelty Processing: Do Brain Responses To Deviance Predict Recall, Recognition And Response Time?, Siri-Maria Kamp

USF Tampa Graduate Theses and Dissertations

Events that violate expectations are biologically significant and accordingly elicit various physiological responses. We investigated the functional relationship between three of these responses: the P300, the Novelty P3 and the pupil dilation response (PDR), with a particular focus on their co-variance with reaction time and measures of subsequent memory. In a modified Novelty P3 oddball paradigm, participants semantically categorized a sequence of stimuli including (1) words of a frequent category, (2) words of an infrequent category (14% of the trials) and (3) pictures of the frequent category (14% of the trials). The Novelty P3 oddball task was followed by a …

Exercise Barriers In Cancer Survivors: A Multi-Dimensional Approach, Morgan Lee

USF Tampa Graduate Theses and Dissertations

The population of cancer survivors is rapidly expanding, and promotion of health and quality of life for these individuals is a priority. Exercise confers numerous general and cancer–specific benefits, yet many cancer survivors are insufficiently active. Research on perceived exercise barriers in cancer survivors has been limited by methodological and conceptual problems. Recent research suggests barriers may be multi–dimensional, and different types of barriers may be salient depending on whether or not a person intends to engage in a given behavior. Global (i.e., abstract) barriers may be negatively associated with intention, while practical (i.e., concrete) barriers may be positively associated …

Physiological And Behavioral Mechanisms Of Range Expansion In The House Sparrow (Passer Domesticus), Andrea Lyn Liebl

USF Tampa Graduate Theses and Dissertations

Introduced species cause both considerable ecological and economic damage every year. However, not much is known about how certain species are able to establish and spread beyond the site of initial introduction, whereas others do not. Species undergoing range expansion following an introduction may prove to be a valuable resource to invasion biology, but may also be informative in light of species' responses to changing environments (i.e. global climate change). Here, I took advantage of an ongoing range expansion of an introduced vertebrate species. House sparrows (Passer domesticus) were introduced to Mombasa, Kenya in the 1950s and have subsequently expanded …

Interrogation Of Epor Fidelity In Myelodysplastic Syndrome Hematopoiesis And Stabilization By The Immunomodulatory Agent, Lenalidomide, Kathy Lynn Mcgraw

USF Tampa Graduate Theses and Dissertations

Myelodysplastic syndromes (MDS) include a spectrum of stem cell malignancies characterized by ineffective hematopoiesis and predisposition to acute myeloid leukemia (AML) transformation. Patients are predominantly older (greater than 60 years old), with progressive cytopenias resulting from ineffective and cytologically dysplastic hematopoiesis. MDS subtypes are classified by morphologic features and bone marrow blast percentage, as well as cytogenetic pattern, as is the case for deletion 5q MDS. Interstitial deletion of the long arm of chromosome 5, del(5q), is the most common chromosomal abnormality in patients with MDS, and the 5q- syndrome, represents a distinct subset of del(5q) MDS characterized by an …

Impacts Of U.S. Foreign Policy And Intervention On Guatemala: Mid-20th Century, Patricia M. Plantamura

USF Tampa Graduate Theses and Dissertations

International Relations theory includes realist concepts of sovereign nation-states interacting in an anarchic world as they rationally determine their own national interests based upon ever-changing competition for power. In this interplay for power, nation-states may affect each other politically, economically, ideologically or militarily. This thesis focuses on effects of U.S. foreign policy and U.S. intervention in Guatemala in the time period surrounding the Guatemalan Revolution (1944-1954), with its "liberation" in 1954, and then into the early 1960s as the Guatemalan state began to be militarized. In this thesis I will answer the following question:

How did the United States affect …

Cultivating Local: Building A Local Food System In Western North Carolina, Allison S. Perrett

USF Tampa Graduate Theses and Dissertations

This dissertation examines a movement in Western North Carolina to build a local food system, one grounded in the conditions and relationships of place. In 2000, Mountain Family Farms launched the Local Food Campaign to raise public awareness about the region's farms and farming heritage, to educate consumers about the benefits of buying food grown by local farms, and, ultimately, to build markets for locally grown food to sustain the region's farms. The campaign sparked a social movement and over a decade later local farms and locally grown food are a palpable feature of life in the mountains of Western …

The Effect Of Rate Change On The Relative Timing Of Speakers With Multiple Sclerosis, Brandlynn N. Reister

USF Tampa Graduate Theses and Dissertations

Relative timing ratios are a useful measure for determining the temporal regularities of speech. The timing intervals that make up these ratios are thought to be important when creating the motor plan for an utterance (Weismer & Fennell, 1985). In fact, these ratios have been shown to be remarkably stable, even when speakers deliberately increase their rate (Tuller & Kelso, 1984; Weismer & Fennell, 1985). The constancy of these ratios also has been demonstrated in speakers with known speech timing disturbances, like the dysarthrias associated with Parkinson's and Huntington's disease (Goberman & McMillan; Ludlow, Connor, & Bassich, 1987; Weismer & …

A Collective Case Study Of The Diagnosis Of Dissociative Disorders In Children, Jacqueline J. Reycraft

USF Tampa Graduate Theses and Dissertations

There is a paucity of research on the diagnosis of dissociative disorders in children. Most children are misdiagnosed with more common mental disorders with similar symptoms. Earlier recognition of dissociative disorders can save years of pain, suffering, and cost. This qualitative collective case study examined the process of diagnosing dissociation in two children under the ages of 12 at the beginning of treatment. A concurrent focus on the training and development of the therapist/researcher is included. Archival data including progress notes, psychotherapy notes, assessments, correspondence, legal documents, school records, and medical records were analyzed using within-case and cross-case analyses to …

Short And Long Term Volcano Instability Studies At Concepción Volcano, Nicaragua, Jose Armando Saballos

USF Tampa Graduate Theses and Dissertations

Concepción is the most active composite volcano in Nicaragua, and is located on Ometepe Island, within Lake Nicaragua. Moderate to small volcanic explosions with a volcanic explosivity index (VEI) of 1-2 have been characteristic of this volcano during the last four decades. Although its current activity is not violent, its volcanic deposits reveal stages of violent activity involving Plinian and sub-Plinian eruptions that deposited vast amounts of volcanic tephra in the Atlantic Ocean. These observations, together with the 31,000 people living on the island, make Concepción volcano an important target for volcanological research.

My research focuses on the investigation of …

The Elimination Of Blindness: An Ethnographic Exploration Of The Fight Against Trachoma In Niger, Kelley Cosby Sams

USF Tampa Graduate Theses and Dissertations

The goal of this study is to explore specialized and popular cultural models of trachoma, and the interaction between the trachoma elimination program and its target audience in one trachoma hyper-endemic intervention community. Eighty four million people worldwide, mainly children, are infected with active bacterial trachoma. For some, this will lead to painful and progressive corneal opacity and eventual blindness. The disease is most commonly spread by person-to-person contact or by flies, and affects very specific populations living in resource-poor areas such as rural Niger, which has one of the highest prevalence rates worldwide.

The World Health Organization formed an …

Aspect Ratio Effect On Melting And Solidification During Thermal Energy Storage, Prashanth Sridharan

USF Tampa Graduate Theses and Dissertations

The present work investigates, numerically, the process of melting and solidification in hollow vertical cylinders, filled with air and phase change material (PCM). The PCM used is sodium nitrate, which expands upon melting. Therefore, a void must be present within the cylinder, which is filled with air. The influence of cylinder shape on melting time is determined. The numerical model takes both conductive and convective heat transfer into account during the melting process. The Volume-of-Fluid (VOF) model is used to track the interface between the PCM and air as the PCM melts. Three dimensionless numbers represent the characteristics of the …

Harmful Algal Blooms Of The West Florida Shelf And Campeche Bank: Visualization And Quantification Using Remote Sensing Methods, Inia Mariel Soto Ramos

USF Tampa Graduate Theses and Dissertations

Harmful Algal Blooms (HABs) in the Gulf of Mexico (GOM) are natural phenomena that can have negative impacts on marine ecosystems on which human health and the economy of some Gulf States depends. Many of the HABs in the GOM are dominated by the toxic dinoflagellate Karenia brevis. Non-toxic phytoplankton taxa such as Scrippsiella sp. also form intense blooms off the Mexican coast that result in massive fish mortality and economic losses, particularly as they may lead to anoxia.

The main objectives of this dissertation were to (1) evaluate and improve the techniques developed for detection of Karenia spp. blooms …

Maximizing Citizenship With Minimal Representation: An Analysis Of Afro-Argentine Civil Society Organizing Strategies, Prisca Suarez

USF Tampa Graduate Theses and Dissertations

This thesis examines the organizing strategies and successes of Afro-Argentine civil society organizations (CSO) in Buenos Aires. I argue that despite low representation, Afro-Argentines have strategically designed their initiatives in ways that draw on national discourses of identity rights and nationalism; and, as well, have used cultural inclusion to influence state actors, creating agency and increasing visibility. Afro-Argentines are a highly understudied population due to the common belief that they do not exist in Argentina as a group. This thesis not only dispels that myth with a history of the long hidden importance of Afro-Argentines contributions to the formation of …

Two Essays On Investor Distraction, Erdem Ucar

USF Tampa Graduate Theses and Dissertations

In theory, all relevant information is incorporated in stock prices timely and completely and therefore prices respond related news quickly in efficient financial markets. In today's information age, technological advances provide investors with fast access to a vast number of information resources. One can argue that these advances can help market efficiency due to easy and quick access to relevant information. On the other hand, these technological advances not only facilitate availability of relevant information but also facilitate availability of all types of information--both relevant and irrelevant information signals. In essence, one can argue that there is (over)exposure to information …

Knowledge, Attitudes And Traditions Regarding Water Consumption And Sanitary Practices Of The Ngäbe-Buglé Indigenous Women In The Chiriquí Province In Panama, Natalia Vega

USF Tampa Graduate Theses and Dissertations

Background: In 2007, approximately 66.2% of the population of the Comarcas (indigenous reservations) in Panama had access to potable water. However, over 50% of this population lacked access to sanitation. As a result, the leading causes of death in the Comarca Ngäbe-Buglé are due to severe diarrhea and gastroenteritis of infectious origin. The present project assessed the need for an in-depth understanding of the Ngäbe-Buglé women and their communities regarding their knowledge, attitudes, beliefs and behaviors about water and sanitation. Methodology: In this cross-sectional exploratory study, a convenience sample of 52 women were interviewed, utilizing a questionnaire guided by the …

A Case Study Of Peer Review Practices Of Four Adolescent English Language Learners In Face-To-Face And Online Contexts, Oksana Vorobel

USF Tampa Graduate Theses and Dissertations

Peer review is a complex collaborative activity, which may engage English language learners in reading, writing, listening, and speaking and carry many potential benefits for their language learning (Hu, 2005). While many research studies focused on peer review practices of adult language learners in academic settings in the USA or abroad in language classes (Grami, 2010; Zhao, 2010), little attention was paid to adolescent L2 writers participating in peer review in face-to-face K-12 and online contexts. This multiple case study aimed at describing and explaining peer review practices of four adolescent ELLs in face-to-face and online contexts from the ecological …

The Influence Of Campus Culture On Mental Health Help-Seeking Intentions, Jason I. Chen

USF Tampa Graduate Theses and Dissertations

Mental health issues are widespread on college campuses. However, the majority of these individuals do not seek help. Prior research suggests many factors which may be related to mental health help-seeking including age, gender, and prior treatment experience. There has however been little work considering the context of the college campus on mental health help-seeking, specifically the influence of campus culture. Accounting for the context of mental health help-seeking may help to determine which social groups have the greatest influence on mental health treatment processes.

The purpose of this study was to explore the relationship between perceived peer, student body, …

Predictors Of The Incidence And Charges For Lumbar Spinal Fusion Surgery In Florida Hospitals During 2010, Anna Ialynychev

USF Tampa Graduate Theses and Dissertations

Over the past several decades rates of spine surgeries in the U.S. have increased dramatically. Spinal fusion surgery rates, in particular, have grown exponentially despite being one of the most costly, invasive, and controversial methods for treating patients suffering from back conditions. Furthermore, lumbar fusion surgeries continue to be performed at increasing rates despite a lack of scientific evidence and consensus that they are cost-effective and produce better clinical outcomes than less radical treatment of lower back pain. As a result, large amounts of healthcare dollars continue to be invested in these costly procedures which are potentially dangerous and have …
