Nonword Processing In Bilingual Five Year Olds: Do Phonotactics Count?, Kyna Betancourt

USF Tampa Graduate Theses and Dissertations

Phonotactic processing is foundational to the word processing task in both monolingual and bilingual children (Li & Farkas, 2002; Pierrehumbert, 2001; Shook & Marian, 2013; Storkel & Morrisette, 2002). While the use of phonotactic information in word processing in monolingual children is relatively well documented, it is less well understood in bilingual children. The purpose of this study was to investigate how bilingual kindergartners process the phonotactic probabilities of their two languages. A set of nonwords was developed that manipulated the strength of phonotactic probability across both Spanish and English while also controlling the language environment of the experimental task …

Reading Assessment Practices Of Elementary General Education Teachers: A Descriptive Study, Sarah Mirlenbrink Bombly

USF Tampa Graduate Theses and Dissertations

In this descriptive study, I researched five elementary general education teachers' reading assessment practices as they worked within the context of IDEA (2004), NCLB (2002) and Response to Intervention (RTI). My own connection to the classroom and reading assessment practices brought me to this research. I presented my personal and professional connection through vignettes about my own classroom assessment practices. Relevant literature on both the context and culture of assessment were pertinent to this research.

I used a qualitative design, specifically, Colaizzi's (1978) method of phenomenological analysis. Data were three in-depth phenomenological interviews, relevant documents and artifacts, and use of …

Defining Semantic Space And Degree Of Association Using Brainwaves: An Erp Investigation Of Alcohol Expectancies, Ty Brumback

USF Tampa Graduate Theses and Dissertations

The current study investigated the cognitive organization of alcohol expectancies using event-related potentials (ERPs). Building on previous behavioral and ERP paradigms, the goal of the current study was to quantify the relationship among alcohol expectancies using ERP indices of salience, congruence, and cognitive distance. The ERP components being evaluated fit perfectly into the alcohol expectancy theory and research; however, implementing specific paradigms to reliably measure individual differences in alcohol expectancies using ERPs has proven to be more elusive than originally thought. This study utilized established cognitive modeling techniques coupled with ERP responses to linguistic stimuli. In essence, this study provides …

Effect Of Localized Corrosion Of Steel On Chloride-Induced Concrete Cover Cracking In Reinforced Concrete Structures, Ezeddin Rafaa Busba

USF Tampa Graduate Theses and Dissertations

Abstract: Concrete cover cracking due to reinforcement corrosion is widely accepted as a limit-state indicator in defining the end of functional service life for existing reinforced concrete (RC) structures undergoing corrosion. Many of the currently available durability prediction models are incapable of providing realistic estimates of remaining service lives of RC structures beyond the corrosion initiation point. Therefore, the need to incorporate the length of the corrosion propagation stage in a comprehensive durability prediction approach has recently received much research attention. Previous research focus however was mostly limited to the case of uniformly corroding reinforcement with only few studies addressing …

Application And Characterization Of Self-Assembled Monolayers In Hybrid Electronic Systems, Michael Enoch Celesin

USF Tampa Graduate Theses and Dissertations

In this study, we explore ultra-thin insulators of organic and inorganic composition and their potential role as high-speed rectifiers. Typical applications for these structures include IR sensing, chemical detection, high speed logic circuits, and MEMS enhancements. While there are many elements in the functional group required to create a rectifying antenna (rectenna), the primary thrust of this work is on the rectifier element itself.

To achieve these research goals, a very good understanding of quantum tunneling was required to model the underlying phenomenon of charge conduction. The development of a multi-variable optimization routine for tunneling prediction was required. MATLAB was …

Predictors Of Student Enrollment Patterns In High School Career Academies, E. Daniel Cox

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to describe participation patterns at the district level of students enrolled in career academies and determine whether participation in career academies is a function of demographic and/or prior learning experience and prior performance variables. Ex-post facto data was used to determine six-year enrollment trends. In addition, both binary logistic regression and multinomial logistic regression methods were employed to determine the extent demographic along with prior learning experience and prior performance variables could be used to predict participation within career academies. Trend data results indicated slight increases in the proportions of students of color (including …

Alliance And Mechanisms Of Medication Adherence In Pediatric Psychiatric Practice, Alessandro Stevens De Nadai

USF Tampa Graduate Theses and Dissertations

Psychiatric medications have been established as an efficacious treatment for pediatric psychopathology (Comer, Olfson, & Mojtabai, 2010), with approximately 3.9% of American children receiving psychotropic medication in a given year (Olfson, Marcus, Weissman, & Jensen, 2002). However, medication adherence for these conditions is suboptimal, with over 50% of children discontinuing treatment before the period recommended for full therapeutic benefit (e.g., Gau et al., 2006; Murray, de Vries, & Wong, 2004). This is highly problematic because pediatric psychopathology is associated with substantial functional impairment and reduced quality of life, as well as increased risk for suicidality (e.g., Bridge, Goldstein, & Brent, …

Distinguishing Processes That Induce Temporal Beach Profile Changes Using Principal Component Analysis: A Case Study At Long Key, West-Central Florida, Denise Marie Davis

USF Tampa Graduate Theses and Dissertations

The heavily developed Long Key is located in Pinellas County in west-central Florida. The structured Blind Pass at the north end of the barrier island interrupts the southward longshore sediment transport, resulting in severe and chronic beach erosion along the northern portion of the island. Frequent beach nourishments were conducted to mitigate the erosion. In this study, the performance of the most recent beach nourishment in 2010 is quantified through time-series beach profile surveys. Over the 34-month period, the nourished northern portion of the island, Upham Beach, lost up to 330 m3/m of sand, with a landward shoreline retreat of …

USF Tampa Graduate Theses and Dissertations

According to many, the legal industry is currently suffering from a professionalism problem. The following dissertation is a response to the question, "What can be done about incivility in the practice of law in Florida?" It begins by exploring the literature examining ethics and professionalism, specifically focusing on the role communication plays in the production and reification of patterns of meaning and action. After contextualizing the professionalism problem socio-culturally and historically, the dissertation next provides an overview of some relevant aspects of the Coordinated Management of Meaning (a theoretical communication framework employed to help make sense of the existing state …

Asbestos Exposure In The Research Laboratory, Ediberto D. Garcia

USF Tampa Graduate Theses and Dissertations

Introduction: Asbestos has been employed in a myriad of industrial applications for more than a century. Of the 181 Mt of asbestos produced worldwide, over 31 Mt was consumed in the U.S. The production and consumption of this mineral eventually was found to cause asbestosis, lung cancer and mesothelioma. While the brunt of the human exposure to asbestos occurred in insulation work, many more workers in other jobs were expose to asbestos fibers. Very little is known about the potential exposure to asbestos in research labs.

Goal: In order to investigate potential research lab work exposures, we simulated lab work …

Effects Of Speech Production Ability On A Measure Of Speech Perception Capacity In Young Children With Cochlear Implants And Their Articulation-Matched Peers, Victoria Beatriz Gonzalez

USF Tampa Graduate Theses and Dissertations

With reductions in the age criterion for cochlear implantation, the need for age-appropriate measures of speech perception skills has increased. One recently developed tool that shows great promise for the clinical assessment of auditory speech perception capacity in young children with cochlear implants is the On-Line Imitative Test of Speech-Pattern Contrast Perception (OlimSpac). The OlimSpac requires a child to imitate nonword utterances by providing a verbal response. The child's perceptual abilities are inferred from the child's productions through having a listener, who is masked to the stimulus select the utterance produced by the child in an eight-alternative force-choice task. Although …

An(Other) Rhetoric: Rhetoric, Ethics, And The Rhetorical Tradition, Kathleen Sandell Hardesty

USF Tampa Graduate Theses and Dissertations

Rhetoric as a discipline is still touched by the shadow of ancient Greece. Rhetoric was defined famously by Aristotle as the "available means of persuasion," codified into five canons in classical Rome, and has since been a central part of Western education to train speakers and writers to effectively move their audiences. However, particularly beginning in the mid-20th Century, the discipline's understanding of rhetoric as a means of persuasion (or even manipulation) passed down from our ancient roots began to shift to a sense of rhetoric as matters of ethics and a concern for the other. It begs the question: …

Static And Dynamic Components Of Droplet Friction, Peter Robert Griffiths

USF Tampa Graduate Theses and Dissertations

As digital microfluidics has continued to mature since its advent in the early 1980's, an increase in new and novel applications of this technology have been developed. However, even as this technology has become more common place, a consensus on the physics and force models of the motion of the contact line between the fluid, substrate, and ambient has not been reached. This uncertainty along with the dependence of the droplet geometry on the force to cause its motion has directed much of the research at specific geometries and droplet actuation methods.

The goal of this thesis is to help …

Human Intention Recognition Based Assisted Telerobotic Grasping Of Objects In An Unstructured Environment, Karan Hariharan Khokar

USF Tampa Graduate Theses and Dissertations

In this dissertation work, a methodology is proposed to enable a robot to identify an object to be grasped and its intended grasp configuration while a human is teleoperating a robot towards the desired object. Based on the detected object and grasp configuration, the human is assisted in the teleoperation task. The environment is unstructured and consists of a number of objects, each with various possible grasp configurations. The identification of the object and the grasp configuration is carried out in real time, by recognizing the intention of the human motion. Simultaneously, the human user is assisted to preshape over …

Understanding Transport Variability Of The Antarctic Circumpolar Current Using Ocean Bottom Pressure, Jessica Makowski

USF Tampa Graduate Theses and Dissertations

Previous studies have suggested that ocean bottom pressure (OBP) can be used to measure the transport variability of the Antarctic Circumpolar Current (ACC). The OBP observations from the Gravity Recovery and Climate Experiment (GRACE) are used to calculate transport along the choke point between Antarctica and Australia. Statistical analysis will be conducted to determine the uncertainty of the GRACE observations using a simulated data set.

There has been some evidence to suggest that Southern Hemisphere winds and the Southern Annular Mode (SAM) or the Antarctic Oscillation (AAO) play a significant role in accelerating/decelerating ACC transport, along with some contribution from …

Evaluating Habitat Vulnerability And Sustainability Of Urban Seagrass Resources To Sea Level Rise, Cynthia A. Meyer

USF Tampa Graduate Theses and Dissertations

The seagrass resource provides essential ecosystem functions for many marine species. This research evaluated the vulnerability and sustainability of the seagrass resource in an urbanized area to the effects of sea level rise. The assessment required analysis of information regarding the biogeography of the seagrass resource, and developing a method to model the spatial extent of the suitable habitat for seagrass, and applying the model to predict the implications of simulated sea level rise scenarios on the seagrass resource.

Examining the biogeography of the seagrass resource required the development of a seagrass monitoring and assessment field survey and a comprehensive …

Two Essays On Stock Repurchases-The Post Repurchase Announcement Drift: An Anomaly In Disguise? And Intra Industry Effects Of Ipos On Stock Repurchase Decisions, Thanh Thiet Nguyen

USF Tampa Graduate Theses and Dissertations

We reexamine the stock price drifts following open-market stock repurchase announcements by differentiating actual repurchases from repurchase announcements and by controlling for the repurchasing firms' earnings improvement in the announcement year relative to the prior year. Our results show that only firms that actually repurchase their shares exhibit a positive post-announcement drift. More importantly, we find that these repurchasing firms have the same post-announcement drift as their matching firms that have similar size and earnings performance but do not repurchase. Further analysis indicates that the post-repurchase announcement drift is not a distinct anomaly but the well-documented post-earnings announcement drift in …

Unusual Patterns Of Seismicity During Eruptive And Non-Eruptive Periods At The Persistently Restless Telica Volcano, Nicaragua, Melanie Rodgers

USF Tampa Graduate Theses and Dissertations

Telica Volcano, Nicaragua, is a persistently restless volcano with high rates of seismicity that can vary from less than ten events to over a thousand events per day. Low-frequency (LF) events dominate the seismic catalogue and seismicity rates at Telica show little clear correlation with periods of eruption. As such, traditional methods of forecasting of volcanic activity based on increases in seismicity and recognition of LF activity are not applicable. A single seismic station has been operating at Telica since 1993, and in 2010 we installed a broadband seismic and continuous GPS network (TESAND network) at Telica. In this study …

Development Of A Confirmatory Pcr Assay To Detect Onchocerca Volvulus In Pools Of Vector Black Flies, Alex Jeanne Talsma

USF Tampa Graduate Theses and Dissertations

Onchocerciasis, or river blindness, has historically represented one of the significant neglected tropical diseases on the planet in terms of socio-economic impact. The discovery that ivermectin was a safe and effective treatment for onchocerciasis, together with the decision of the manufacturer to donate the drug for the treatment of this disease became the basis for several large international programs to control and eventually eliminate the infection. These programs have managed to virtually eliminate transmission of the parasite causing Onchocerca volvulus from many foci in Africa and the Americas. Verifying that transmission has been halted requires sensitive and specific assays to …

One Dimensional Stochastic Coating Growth Kinetics Of Peg 3400 Onto Ammonium Nitrate In A Fluidized Bed, Brandon Smeltzer

USF Tampa Graduate Theses and Dissertations

Fluidized beds represent a cost effective, scalable technology invaluable to the chemical processing community as part of the global scheme of particle design. However, despite wide spread use and multiple approaches (empirical and mechanistic) to modeling a fluidized bed coating process, operations must be done at different scales due to changes within the balance of phenomenological forces (e.g. gravity, buoyancy, drag, surface tension, viscosity, kinetic energy).

Ammonium nitrate is synthetic compound that has multiple applications such as fertilizer, rocket fuel, and self-cooling applications. Ammonium nitrate has five temperature dependent crystal structures that are accompanied by a change in density. The …

Adolescent Literacy Practices And Positive Youth Development Through Fink's Taxonomy Of Significant Learning, Paula Taylor-Greathouse

USF Tampa Graduate Theses and Dissertations

The purpose of this study was not to disprove the effects of the current, common remedial literacy course design and the literacy practices within that help adolescent RLLs pass statewide assessment tests, but to describe the potential long-term impact of an innovative comprehensive approach to literacy (CAL) framed through an integrated course design model. In this study I sought to determine if the 2012 CAL design with a particular demographic of student produced "significant" or lasting learning as defined by Fink (2003). In other words, did the 2012 CAL design promote sustained or increased practices of literacy and PYD over …

Complete Genome Sequences And Phylogeny Of West Nile Virus Isolates From Southeastern United States, 2003-2012, Crystal Wedin

USF Tampa Graduate Theses and Dissertations

The study of the evolution and phylogeny of West Nile virus (WNV) has been an important area of research since the introduction of WNV in 1999. However, genome sequencing of isolates from the Southeastern part of the United States has been somewhat limited. To determine how WNV has evolved at a more localized level, ten isolates from Florida and Georgia from 2003-2012 were completely sequenced using Illumina's next-generation technology. In addition, a phylogenetic comparison of both the complete genome and select partial genomes was completed to ensure consistency among the results. This study further demonstrated the dominance of the North …

The Dynamics Of Alcohol Consumption In The Russian Federation: Implications Of Using Price Related Policies To Control Alcohol Use, Arseniy Pavlovich Yashkin

USF Tampa Graduate Theses and Dissertations

This dissertation models the dynamics of alcohol use in the Russian Federation with an emphasis on identifying policy implications most likely to be effective at controlling alcohol use. Utilizing data from The Russian Longitudinal Monitoring Survey, models of alcohol consumption are estimated using both myopic and rational specifications via ordinary least squares, fixed effects two stage least squares and, the focus of this study, two-step system generalized method of moments. Alcohol consumption is studied both as a composite good and as a distinct beverage category (wine, beer, and hard liquor). Furthermore, equations stratified by gender and rural status are included …

Improving Implementation Of A Regional In-Line Chlorinator In Rural Panama Through Development Of A Regionally Appropriate Field Guide, Benjamin A. Yoakum

USF Tampa Graduate Theses and Dissertations

Access to safe drinking water has a direct effect on improving human health and their quality of life. One country still struggling with providing access to safe drinking water to all of its population is Panama. Panama's largest indigenous group, the Ngöbe people, is disproportionately affected by lack of access to safe drinking water. One way Panama's Ministry of Health (MINSA) is attempting to increase access to safe drinking water to the Ngöbe people is by disinfecting the water already captured by rural gravity fed water systems constructed within in the Ngöbe-Bugle reservation. This is accomplished using an in-line chlorinator …

Environmental Effects On The Biomechanics And Motor Physiology Of Elastically Powered Movements In Chameleons, Christopher Van Anderson

USF Tampa Graduate Theses and Dissertations

Environmental temperature exhibits profound effects on the activity and ecology of ectotherms through its impact on muscle contractile physiology. While the performance of locomotor behaviors powered by muscle contraction directly decreases by at least 33% over a 10°C drop in body temperature, chameleons are known to feed, presumably with high performance, at body temperatures where sympatric lizard species remain inactive. I propose that ballistic movements that are powered by the recoil of preloaded elastic and collagenous tissues are less thermally dependent than movements that rely on direct muscular power. Despite the reduced thermal sensitivity of the elastic-recoil powered movement, I …

A Comparative Perspective Of Black College Males On The Achievement Gap: Implications For School Counselors, Detra Bethell

USF Tampa Graduate Theses and Dissertations

The dominant discourse regarding Black males in America is that they are less academically successful than European American males and Black females. Similarly, Black males in the Bahamas are described as less successful than Black Bahamian females. School Counselors are in a unique position to alter the trajectory of success for Black males if they are knowledgeable of factors contributing to Black male academic success; have an awareness of the potential impact their unique roles can have; and develop and execute comprehensive, culturally responsive school counseling programs. While there is little research on the Achievement Gap in the Bahamas, much …

Factors Prospective Students Consider When Selecting An Mba Program, Lorie Plyler Briggs

USF Tampa Graduate Theses and Dissertations

This paper adds to existing literature regarding MBA selection processes and helps identify and better understand the needs that motivate consumers to pursue an MBA degree. Through a series of qualitative, one-on-one interviews with 17 brand-new MBA students or prospective students, this research found that while many people have "always wanted" to earn the advanced degree, most have toyed with the idea of a graduate business degree for many years. The most frequent reasons that people cite regarding their decision to seriously consider an MBA at a large southern university centers around four desires. These are, not surprisingly, the desire …

Nietzsche And Heidegger On The Cartesian Atomism Of Thought, Steven Burgess

USF Tampa Graduate Theses and Dissertations

My dissertation has two main parts. In the first half, I draw out an underlying presupposition of Descartes' philosophy: what I term "atomism of thought." Descartes employs a radical procedure of doubt in order to show that the first principle of his philosophy, the cogito, is an unshakeable foundation of knowledge. In the dialogue that follows his dissemination of the Meditations, Descartes reveals that a whole set of concepts and rational principles innate in our minds are never doubted. These fundamental units of thought are indivisible, distinct, and isolated, and enable the possibility of any rational demonstration. Atoms of …

Prediction Of The Performance Of A Flexible Footing On A Stone-Column Modified Subgrade, Justin Callahan

USF Tampa Graduate Theses and Dissertations

When foundations are designed on weak clay layers, it is a common practice to modify the subgrade by installing stone columns. Currently used methods for determining the level of ground modification, represented by the percentage of soil replaced (replacement ratio), assume a rigid foundation. These analytical methods provide the designer with the potential settlement reduction based on the compressibility parameters of the subgrade and the replacement ratio. The deficiencies of these methods are the assumption of rigidity of the foundation and the consideration of the settlement reduction as the only design criterion. Furthermore, they do not consider the effects that …

The Harm Of Influence: When Exposure To Homosexuality Elicits Anger And Punishment Tendencies, Timothy Andrew Caswell

USF Tampa Graduate Theses and Dissertations

In the current project, I examined the distinct elicitors and behavioral outcomes of anti-gay anger and anti-gay disgust. The CAD triad hypothesis (Rozin, Lower, Imada, & Haidt, 1999) suggests that anger and disgust are elicited by distinct moral violations and cognitive appraisals. A plethora of research has documented the strong link between disgust and sexual prejudice, but very little attention has been given to the role of anger in sexual prejudice. The biocultural framework of stigmatization (Neuberg, Smith, & Asher, 2000) suggests that people who counter-socialize against prevailing social norms are stigmatized by others. If homosexual sexual behavior does not …
