“Black Americans And Hiv/Aids In Popular Media” Conforming To The Politics Of Respectability, Alisha Lynn Menzies

USF Tampa Graduate Theses and Dissertations

This dissertation examines narratives about racialized gender, sexuality, and class through media images of black Americans with HIV/AIDS. Through textual analysis of media sites featuring HIV/AIDS and blackness (The Announcement, Precious, and Marvelyn Brown’s website, www.marvelynbrown.com), this project analyzes how the politics of respectability—a set of precepts that govern how black men and women can present themselves in public spaces to align with white ideals of gender and sexuality—construct black people in media representations of HIV/AIDS. This work examines how respectability politics deployed in media representations of HIV/AIDS and black Americans reclaim notions of acceptable black sexuality …

Analyzing Spelling Errors By Linguistic Features Among Children With Learning Disabilities, Christine Johnson

USF Tampa Graduate Theses and Dissertations

In order to spell fluently and accurately, phonology, orthography, and morphology must be integrated and stored into long term memory (Berninger & Richards, in press; Berninger, Nagy, Tanimoto, Thompson, Abbott, 2015). Children with dysgraphia, dyslexia, and OWL-LD have specific deficits in linguistic processing that impede the cross-mapping of these linguistic elements. This study analyzes the frequency and nature of spelling errors produced by children with dysgraphia, dyslexia, and OWL-LD during an academic writing task in order to determine if known deficits in linguistic processing affect the type and severity of spelling errors made by these children.

The present study analyzed …

Work-Value Profile And Career Success, Chee Wee Koh

USF Tampa Graduate Theses and Dissertations

Work values, defined as the end states people desire and expect to realize through work, appear to play a role in career success, but the small number of past studies have reported conflicting results, some of which may be attributed to research methodology. Using a person-centered approach to model the conjoint effects of intrinsic and extrinsic work values, the present study inductively investigated the association between work-value profile and career success using a three-panel longitudinal dataset consisting of 905 lawyers from the After the Juris Doctorate (AJD) study. Latent profile analysis identified five work-value profiles: (i) Neither Intrinsic nor Extrinsic …

USF Tampa Graduate Theses and Dissertations

Lymphatic filariasis (LF) is an incapacitating disease caused by three filarial nematodes belonging to the family Onchocercidae, namely Brugia timori, Wuchereria bancrofti and Brugia timori. An estimated 90% of lymphatic filariasis cases globally are caused by Wuchereria bancrofti. To evaluate the success of the Global Program to eliminate Lymphatic Filariasis it is essential to monitor the frequency of larval infection in the mosquito vector. Molecular methods to detect Wuchereria bancrofti DNA in mosquitoes have been in existence since 1996. However these methods have not been widely adopted due to the high cost associated with them and the inability …

White Teachers’ Experiences Of Working With Black Students Within A Response To Intervention Framework: The Role Of Racialized Deficit Thinking, Sujay Sabnis

USF Tampa Graduate Theses and Dissertations

Response to Intervention (RTI) is a data-based decision-making framework of service delivery that has the potential to improve educational outcomes for all students. Preliminary data appear to bolster this claim. However, it is as yet unclear whether RTI will be able to close the gap in educational outcomes that exists between students of different racial groups. Drawing on theories such as culture of policy (Stein, 2004) and deficit thinking (Valencia, 2010), this study explored the experiences of six White elementary teachers using RTI while working with Black students receiving Tier 2 or Tier 3 instructional supports. Using theoretically driven constant-comparative …

Automated Device To Measure Slurry Properties In Drilled Shafts, Miles Patrick Mullins

USF Tampa Graduate Theses and Dissertations

Slurry is the fluid within a drilled excavation that is introduced when an excavation is deeper than the water table or where additional stability is needed for loose sandy dry soils. Although construction practices vary greatly throughout the country and the world, slurry levels should be maintained above the existing ground water level by a suitable margin. The most widely used slurry type is mineral slurry formed by mixing dry clay powder with water; either bentonite or attapulgite powder may be used (attapulgite being used in saline water conditions). Regardless of whether the slurry material is mineral, polymer or natural, …

Media Representations Of Abortion Politics In Florida: Feminist Geographic Analysis Of Newspaper Articles, 2011-2013, Jennifer Iceton

USF Tampa Graduate Theses and Dissertations

Feminist geographers argue that gendered bodies and power are deeply entwined (McDowell 1992; Rose 1993). However, few geographers have investigated how gender and power interact in relation to the politics of abortion access. This thesis seeks to fill this gap by conducting a feminist content analysis of six newspapers from Florida’s three largest metropolitan areas to determine how articles featuring abortion are framed. Analysis of the dataset concludes that the politicization of the abortion debate results in the erasure of women from the conversation, the identification of a pregnant women trope which homogenizes all women into one category, and Planned …

Photic Stress In Symbiont-Bearing Reef Organisms: Analyses Of Photosynthetic Performance, Natasha Mendez-Ferrer

USF Tampa Graduate Theses and Dissertations

Photo-oxidative stress is one of the key factors that can induce bleaching in reef organisms. With the decline of coral reefs and recurrent bleaching events, many studies have focused on understanding the mechanism behind this phenomenon. Two of the hypotheses that explain how the photosynthetic performance of the symbiont is affected and influences bleaching are: (1) disruption of the photosynthetic pathway by direct damage to the photosystem II (PSII), and (2) by inhibition of the Calvin-Benson cycle. In this dissertation I examine different aspects of photosynthetic performance in symbiont-bearing reef organisms and how this is influenced by symbiont loss and …

Cell Cycle Arrest By Tgfß1 Is Dependent On The Inhibition Of Cmg Helicase Assembly And Activation, Brook Samuel Nepon-Sixt

USF Tampa Graduate Theses and Dissertations

Tumorigenesis is a multifaceted set of events consisting of the deregulation of several cell-autonomous and tissue microenvironmental processes that ultimately leads to the acquisition of malignant disease. Transforming growth factor beta (TGFß) and its family members are regulatory cytokines that function to ensure proper organismal development and the maintenance of homeostasis by controlling cellular differentiation, proliferation, adhesion, and survival, as well as by modulating components of the cellular microenvironment and immune system. The pleiotropic control by TGFß of these cell intrinsic and extrinsic factors is intimately linked to the prevention of tumor formation, the specifics of which are dependent on …

This study examined the effects of four different home range estimation techniques on the proportions of habitats located therein. The study utilized a point dataset collected for twenty individual Florida Black Bears (Ursus americanus floridanus), occurring in five different areas throughout the state of Florida. Each dataset was used to create home ranges using the following techniques: (1) Minimum Convex Polygon, (2) Kernel Density Estimation, (3) Characteristic Hull Polygon, and (4) Time-Geographic Density Estimation, a new home range …

Static And Dynamic Spectral Acuity In Cochlear Implant Listeners For Simple And Speech-Like Stimuli, Benjamin Anderson Russell

USF Tampa Graduate Theses and Dissertations

For cochlear implant (CI) listeners, poorer than normal speech recognition abilities are typically attributed to degraded spectral acuity. However, estimates of spectral acuity have most often been obtained using simple (tonal) stimuli, presented directly to the implanted electrodes, rather than through the speech processor as occurs in everyday listening. Further, little is known about spectral acuity for dynamic stimuli, as compared to static stimuli, even though the perception of dynamic spectral cues is important for speech perception.

The primary goal of the current study was to examine spectral acuity in CI listeners, and a comparison group of normal hearing (NH) …

Effects Of A Novel Right Brain Intervention On Stuttering Frequency In Unfamiliar Speech Tasks, Chelsea Beatrice Stewart

USF Tampa Graduate Theses and Dissertations

Developmental stuttering persists in approximately 1% of the United States population. Stuttering has been shown to impact overall quality of life. The present study examines the effects of a Novel Right Brain Intervention on two female participants with persistent developmental stuttering. The aim of the study was to determine whether encouraging greater activation of the right hemisphere, specifically the pre-SMA, via complex left-handed movements, prior to speech production, would lead to a reduced stuttering frequency and severity in people who stutter (PWS). It was hypothesized that each participant would reduce stuttering symptoms and behaviors following the intervention due to the …

Relationship Between Teacher Characteristics And Accuracy In Identifying Middle School Students With Symptoms Of Anxiety And Depression, Elizabeth Storey

USF Tampa Graduate Theses and Dissertations

As a universal screening method, teacher nominations have been found to both miss and misidentify a substantial proportion of students with internalizing disorders such as anxiety and depression (Cunningham & Suldo, 2014; Gelley, 2014; Moor et al., 2007). Although some research has explored the accuracy of teacher nominations when used to identify students with anxiety and depression, no research examined the teacher characteristics that are potentially related to accuracy. The current study conducted a secondary analysis of an archival dataset (Gelley, 2014) to determine which characteristics of teachers (N= 19) are more closely related to accuracy in identifying …

Analysis Of Patterns In Handwritten Spelling Errors Among Students With Various Specific Learning Disabilities, Laura Ann Winkler

USF Tampa Graduate Theses and Dissertations

Students diagnosed with specific learning disabilities struggle with spelling accuracy, but they do so for different reasons. For instance, students with dysgraphia, dyslexia, and oral-written language learning disability (OWL-LD) have distinct areas of weakness in cognitive processing and unique difficulties with the linguistic features necessary for accurate spelling (Silliman & Berninger, 2011). This project considered the spelling errors made by such students to determine if their unique learning profiles lead to distinct misspelling patterns.

Academic summaries handwritten by 33 students diagnosed with dysgraphia (n=13), dyslexia (n=15), and OWL-LD (n=5) were analyzed for type/complexity and …

The Influence Of Motivational Salience On Attention Selection: An Erp Investigation, Constanza De Dios

USF Tampa Graduate Theses and Dissertations

The current study used event-related potentials (ERPs) to investigate how motivational salience in the form of expectation violation influences spatial attention. The medial frontal negativity (MFN) ERP indexes expected value, being negative to unexpected punishments and positive to unexpected rewards. The P1 and N1 ERPs index spatial attention, being larger to stimuli in attended locations. This design attached motivational value to locations by making one visual hemifield economically rewarding (greater probability of a rewarding outcome) and the other punishing (greater probability of a punishing outcome). Keypresses to a dot probe following a reward-signifying stimulus were awarded money if correct, and …

Effects Of A Novel Right Brain Intervention On Stuttering In Familiar And Structured Speech Tasks, Josalyn Elizabeth Perry

USF Tampa Graduate Theses and Dissertations

Over 3 million Americans are disfluent due to developmental stuttering. Current evidence-based treatments typically consist of a rigorous schedule of intensive therapy, followed by the need for maintenance of skills, placing high demands on self-monitoring of one’s speech at all times. Relapse after treatment is very common, at 84%. The demand for further research into treatment possibilities for stuttering is on the forefront. Previous research has connected neural activations in people who stutter (PWS) and people with chronic nonfluent aphasia. The aim of this study was to determine if a novel intervention, based on a treatment for anomia, would change …

Tongue Twisters Quantified: Ultrasound Analysis Of Speech Stability And Speech Errors, Karen Reddick

USF Tampa Graduate Theses and Dissertations

This thesis investigates errors on speech sounds (or phonemes) produced in laboratory speech stimuli designed to generate phonological onset errors. The present study adds to the literature on phonological speech errors with an instrumental analysis of tongue posture during speech error production and an investigation of the nature of speech errors as unintended variation in articulation.

This study utilized ultrasound instrumentation to visualize speech errors made on velar and alveolar stop consonants at the point of stop closure. Two types of errors were of interest, categorical errors and gradient errors. Categorical errors are those that are heard by the listener …

Oversampling Methods For Imbalanced Dataset Classification And Their Application To Gynecological Disorder Diagnosis, Iman Nekooeimehr

USF Tampa Graduate Theses and Dissertations

In many applications, the dataset for classification may be highly imbalanced where most of the instances in the training set may belong to some of the classes (majority classes), while only a few instances are from the other classes (minority classes). Conventional classifiers will strongly favor the majority class and ignore the minority instances. The imbalance problem can occur in both binary data classification and also in ordinal regression. Ordinal regression is a supervised approach for learning the ordinal relationship between classes. Extensive research has been performed for addressing imbalanced datasets for binary classification; however, current methods do not address …

Teaching Perspective Taking To Adults With Traumatic Brain Injury, Jacqueline Cohen

USF Tampa Graduate Theses and Dissertations

Approximately 1.7 million people sustain a traumatic brain injury each year in the United States. Perspective taking is a repertoire known to be severely affected following a traumatic brain injury. The ability to take the perspective of another greatly contributes to social interactions and involves a complex set of skills. A small number of studies have attempted to train perspective taking skills in populations lacking the ability, but none with individuals diagnosed with TBI. This study aimed to teach perspective taking skills to adults with TBI through established protocols which teach deictic relational frames. Three adult males with traumatic brain …

Evaluating Video Modeling To Teach Caregivers To Conduct Paired-Stimulus Preference Assessments, Cristina Diane Andersen

USF Tampa Graduate Theses and Dissertations

Stimulus preference assessments have been shown to identify stimuli that are likely to function as reinforcers for individuals with disabilities. It is important to identify these stimuli to increase the effectiveness of interventions. The ability to conduct a stimulus preference assessment is a skill that parents and caregivers should have. Research on training preference assessments is limited to staff, teachers, and students. The following study evaluated the effectiveness of video modeling to teach caregivers to conduct paired stimulus preference assessments. The results showed that video modeling was effective and that the results maintained during a one week follow up.

Enforcing Security Policies On Gpu Computing Through The Use Of Aspect-Oriented Programming Techniques, Bader Albassam

USF Tampa Graduate Theses and Dissertations

This thesis presents a new security policy enforcer designed for securing parallel computation on CUDA GPUs. We show how the very features that make a GPGPU desirable have already been utilized in existing exploits, fortifying the need for security protections on a GPGPU. An aspect weaver was designed for CUDA with the goal of utilizing aspect-oriented programming for security policy enforcement. Empirical testing verified the ability of our aspect weaver to enforce various policies. Furthermore, a performance analysis was performed to demonstrate that using this policy enforcer provides no significant performance impact over manual insertion of policy code. Finally, future …
