The study took place in Hillsborough County, in residential areas that contain all of these habitat types. Five GPS devices, designed for wildlife tracking purposes, were used to collect the data needed for this study. GPS data was collected under the …

Increasing Parental Involvement In Early Childhood Education, Kendall Jeffries

USF Tampa Graduate Theses and Dissertations

Parental involvement during preschool has been linked with stronger pre-literacy skills, acquisition of mathematical skills, well-developed social skills, and positive attitudes toward school (Arnold, Zeljo, Doctoroff, & Ortiff, 2008; Powell, Son, File, & San Juan, 2010). Parents' active involvement in their children's learning is a recommended strategy in engaging families in children's education experiences (Henderson & Mapp, 2002). The purpose of the current study was to measure the impact of parents' active participation in a parent-directed early literacy intervention on parental home-based involvement, school-based involvement, and home-school conferencing among Head Start parents and their preschool-aged children.

Community As Metaphor: Dialectical Tensions Of A Racially Diverse Organization, Joseph Jacob Jenkins

USF Tampa Graduate Theses and Dissertations

In recent years, a sense of community has declined throughout the United States. Common Point Community Church has responded to this trend by prioritizing "community" as an organizational metaphor. The present study explores how this metaphor is co-constructed through the communication practices of current organizational leaders and members. I begin this process, first, by positioning the study within existing literature on institutional theory, institutional legitimacy, community, community of practice, social construction of race, sensemaking, organizational metaphor, tension-centered approach, and dialectic theory. Building upon more than three years of ethnographic field work, I then outline the study's context and methodology. Next, …

Being Present At Work And At Home: Can A Mindfulness-Based Intervention Reduce Work-Family Conflict?, Kaitlin M. Kiburz

USF Tampa Graduate Theses and Dissertations

Past research has found that work-family conflict is related to trait mindfulness, a unique disposition due to its amenability to change through training. This longitudinal study incorporated a mindfulness-based intervention including a mindfulness-based workshop and behavioral self-monitoring (BSM) in an attempt to reduce work-family conflict in employees. Trait mindfulness was correlated with work-family conflict across time. The intervention increased participants' trait mindfulness and decreased WIF, but did not reduce FIW. There was minimal support for the moderating roles of negative affect and perceived stress on the impact of the intervention. Overall the results provide support for the efficacy of mindfulness-based …

Development And Optimization Of Kinetic Target-Guided Synthesis Approaches Targeting Protein-Protein Interactions Of The Bcl-2 Family, Sameer Shamrao Kulkarni

USF Tampa Graduate Theses and Dissertations

Kinetic target-guided synthesis (TGS) and in situ click chemistry are among unconventional discovery strategies having the potential to streamline the development of protein-protein interaction modulators (PPIMs). In kinetic TGS and in situ click chemistry, the target is directly involved in the assembly of its own potent, bidentate ligand from a pool of reactive fragments. Herein, we report the use and validation of kinetic TGS based on the sulfo-click reaction between thio acids and sulfonyl azides as a screening and synthesis platform for the identification of high-quality PPIMs. Starting from a randomly designed library consisting of nine thio acids and nine …

Semantic Feature Distinctiveness And Frequency, Katherine Marie Lamb

USF Tampa Graduate Theses and Dissertations

Lexical access is the process in which basic components of meaning in language, the lexical entries (words) are activated. This activation is based on the organization and representational structure of the lexical entries. Semantic features of words, which are the prominent semantic characteristics of a word concept, provide important information because they mediate semantic access to words. An experiment was conducted to examine the importance of semantic feature distinctiveness and feature frequency in accessing the lexical representations of young and older adults in an off-line task using features of animals. The McRae, Cree, Seidenberg, and McNorgan (2005) feature norm corpus …

Wrecking Recreation Center Relationships: How Policy Affects Urban Youth In Tampa, Florida, Brett A. Mervis

USF Tampa Graduate Theses and Dissertations

This dissertation explores the impact of housing and recreation policy on Tampa's urban youth. Deconcentration policy suggests that public housing youth have improved life chances when relocated to mixed-income neighborhoods. In 2007, Tampa's Central Park Village (CPV) public housing complex was demolished and all families were relocated to new neighborhoods. Similarly, neoliberal policy advocates for the government's reduced role in poverty-alleviating mechanisms to include housing the poor and the funding of afterschool programs. To offset a smaller city budget due to state property tax rollbacks in the mid-2000's, Tampa Parks and Recreation instituted increased afterschool and youth sports participation fees. …

Academic Affairs Officers: An Application Of The American Association Of Community Colleges Competencies For Community College Leaders, Misty Renee Price

USF Tampa Graduate Theses and Dissertations

Over the last two decades, several studies have confirmed that there is a leadership crisis among the nation's community colleges. In response to this leadership crisis, the American Association of Community Colleges [AACC] commissioned the development of a leadership competency framework consisting of six leadership competency areas deemed "either `very' or `extremely' essential to the effective performance of community college leaders." Since the release of this framework, limited research has been conducted on the importance of and the preparation in the identified competencies. The majority of research that has been conducted has focused on the position of president, even though …

Responses To Chemical Exposure By Foraminifera: Distinguishing Dormancy From Mortality, Benjamin James Ross

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout in 2010 released an estimated 4.9 million barrels of crude oil into the Gulf of Mexico in the 83 days between the initial explosion and the capping of the well. Response included extensive use of Corexit© oil dispersant. Although South Florida was spared exposure by currents, this event highlights the need for effective bioassay organisms for coral reefs. Amphistegina spp. are benthic foraminifers that host diatom symbionts in a relationship similar to that of coral and their zooxanthellae. Amphistegina spp. occur abundantly in reef communities nearly worldwide, are easily collected and maintained in culture, and are …

The Rhetoric Of Evidence In Recent Documentary Film And Video, Steven W. Schoen

USF Tampa Graduate Theses and Dissertations

Documentary is a genre of film that portrays "real" events using depictions that connote the objectivity and facticity implied by the processes of photorealism. Many contemporary documentary theorists and critics observe a constitutive problem in this ethos: despite the apparent constructions and agendas of documentary filmmaking, the framing and assumption of documentary as a window on the world tend to naturalize its own constructions as "real." Critics who engage documentary trace the multitude of ways this problem plays out in particular films. These projects yield many important insights, but they most often approach documentary as a form of inherently deficient …

Cyberwar And International Law: An English School Perspective, Anthony F. Sinopoli

USF Tampa Graduate Theses and Dissertations

Cyberwar challenges future endeavors of state security. As technological capability has improved, and access to information has become more widespread the importance of the issue in today's ever-globalizing world grows each day. A primary objective is to evaluate the place of cyber-warfare against nation-states and any repercussions under an international law paradigm. Utilizing an English School perspective, emphasis will be applied to the argument that disruptive circumstances could come to fruition if international conventions are not created to bring consensus and order among nation-states on this subject. This study hypothesizes that a future application could be an agreement under international …

Dolphin Sound Production And Distribution On The West Florida Shelf, Peter Simard

USF Tampa Graduate Theses and Dissertations

This dissertation is an investigation of dolphin sound production and distribution off west central Florida. Although a wealth of information exists on the production of common sounds (whistles, echolocation) made by captive, trained dolphins, far less is known about free-ranging dolphin sound production and of unusual sounds. In addition, while inshore dolphin populations or communities are the subjects of research projects in many locations, dolphins in offshore waters are less commonly studied. The objectives of this dissertation were to contribute information on free-ranging dolphin sounds and continental shelf dolphin distribution.

While echolocation has been rigorously studied in captive, trained dolphins, …

Improvisational Music Performance: On-Stage Communication Of Power Relationships, David A. Steinweg

USF Tampa Graduate Theses and Dissertations

This project explores how musical improvisational processes come into being through interacting discursive power relationships that are embodied and enacted through performance. By utilizing the concepts of framing and performativity I am able to show how discursive power constitutes the performance of improvisational music. To exemplify this theory, the project presents a case study examining a Grateful Dead cover band named Uncle John's Band that performs at Skipper's Smokehouse in Tampa, FL. Using an ethnographic methodology, the project articulates the dominant discursive power relationships that constitute Uncle John's Band's improvisational performances. The dominant discursive power relationships revolve around the lived …

Two Essays On Corporate Governance, Yuwei Wang

USF Tampa Graduate Theses and Dissertations

This dissertation includes two related chapters that investigate corporate governance. In the first chapter, we examine the effectiveness of board monitoring on CEOs. It is widely believed that outsider boards are better monitors. In fact, regulations now require that the board of directors of publicly traded firms be composed of a majority of independent directors (or outsiders). However, this paper documents that an insider-dominated board can monitor the CEO just as well as an outsider board can when the firm's CEO is hired from outside. The results suggest that what matters is not so much as the structure of the …

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Finding ways to improve nutritional and physical activity components with today's adolescents is a significant problem. The obesity epidemic is over 10 years old and little research has been done on successful interventions that motivate today's students using the latest technology. A total of 140 middle school students and four physical education teachers participated in a 4-week study using a newly created application (AFIT app) for supplemental teaching in and out of the classroom. Combining a theoretical framework of Self-Determination and motivating strategies implored in today's mobile technology, significance was found using the PACE (2001) instrument in fruits and …

A Longitudinal Investigation Of Stress, Complete Mental Health, And Social Support Among High School Students, Ashley Chappel

USF Tampa Graduate Theses and Dissertations

Examinations of stress in relation to adolescent mental health have not often utilized a comprehensive definition of psychological functioning. Recent literature has found support for the importance of examining optimal psychological functioning as the presence of high life satisfaction in addition to low psychopathology (Antamarian, Huebner, Hills, & Valois, 2011; Suldo & Shaffer, 2008). Most research on stress has focused on either major stressful events or chronic environmental stressors; further research is needed on the psychological model of stress, which conceptualizes stress as involving both environmental events and one's cognitive appraisals of the stressor. The current longitudinal study determined how …

A Phenomenological Study Of Teaching Endangered Languages Online: Perspectives From Nahua And Mayan Educators., Dustin De Felice

The purpose of this thesis is to examine the crimes of a coal mining corporation, a corporation whose business decisions led to the worst coal mining disaster in forty years, along with the deaths of twenty-nine men. This thesis will utilize a case study format in order to illustrate the crimes committed by this corporation. Previous literature covering the history of …

Methods And Algorithms For Scalable Verification Of Asynchronous Designs, Haiqiong Yao

USF Tampa Graduate Theses and Dissertations

Concurrent systems are getting more complex with the advent of multi-core processors and the support of concurrent programs. However, errors of concurrent systems are too subtle to detect with the traditional testing and simulation. Model checking is an effective method to verify concurrent systems by exhaustively searching the complete state space exhibited by a system. However, the main challenge for model checking is state explosion, that is the state space of a concurrent system grows exponentially in the number of components of the system. The state space explosion problem prevents model checking from being applied to systems in realistic size. …

Exploring The Advance Care Planning Experiences Among Persons With Mild Cognitive Impairment: Individual And Spousal Perspectives, Catherine Parsons Emmett

USF Tampa Graduate Theses and Dissertations

Advance Care Planning has been advocated for over 20 years as a way in which individuals who are no longer able to speak for themselves, may still convey their preferences regarding a wide of array of decisions, including medical care. Advance care planning may not be initiated by individuals for many reasons, and even when initiated, may not be specific enough to help guide decision making. Recent advance care planning models have utilized disease specific information to help guide end of life health care decision-making. Persons diagnosed with mild cognitive impairment face an increased possibility of developing dementia at some …

Comparing Prompt Delay And Total Communication For Training Vocal Intraverbals In Children With Autism, Rosana Pesantez

USF Tampa Graduate Theses and Dissertations

Abstract

Verbal behavior encompasses a wide range of aspects in our everyday lives and in the activities of a society. Many verbal behavior interventions often include programs to teach answering questions, these responses are referred to as intraverbals. Previous research has demonstrated a higher rate of acquisition of verbal targets such as mands and tacts for children with a limited verbal repertoire when a presentation of both sign and vocal prompts occur simultaneously (Total Communication), in comparison to sign-alone or vocal-alone trainings. However, an important variable not often examined in the literature is the comparison of Total Communication (TC) and …

A Framing Analysis: The Nba's "One-And-Done"Rule, Daniel Ryan Beaulieu

USF Tampa Graduate Theses and Dissertations

In 2006, the NBA introduced the "one-and-done" rule that restricted high school graduates to enter directly into the NBA draft following high school. In turn, a high school prospect would essentially now have the option of playing professionally elsewhere (most likely overseas), enter the NBA's Developmental League, or play NCAA basketball. The rule has proved to be quite controversial, as it has had a great effect on both NBA and NCAA basketball, as well as the players. Various media outlets have been quite vocal not only about the rule itself, but the perceived effects it has had on both collegiate …

Aberrant Sialylation Alters Cardiac Electrical Signaling, Andrew Ednie

USF Tampa Graduate Theses and Dissertations

In the heart, electrical signaling is responsible for its rhythmicity and is necessary to initiate muscle contraction. The net electrical activity in a cardiac myocyte during a contraction cycle is observed as the action potential (AP), which describes a change in membrane potential as a function of time. In ventricular cardiac myocytes, voltage-gated sodium channels (Nav) and voltage-gated potassium channels (Kv) play antagonistic roles in shaping the AP with the former initiating membrane depolarization and the latter repolarizing it. Functional changes in the primary cardiac Nav isoform, Nav 1.5, or any one of the many Kv isoforms expressed in the …
