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 …

Furthermore, to develop differential equations that will characterize the behavior of the pancreatic cancer tumor size as a function of time. Having such differential equations, the mean solution of which once plotted will identify the rate of change of tumor size as a …

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. …

USF Tampa Graduate Theses and Dissertations

Abstract

This thesis investigates the use of socioscientific issues (SSI) in the high school science classroom as an introduction to argumentation and socioscientific reasoning, with the goal of improving students' scientific literacy (SL). Current research is reviewed that supports the likelihood of students developing a greater conceptual understanding of scientific theories as well as a deeper understanding of the nature of science (NOS), through participation in informal and formal forms of argumentation in the context of SSI. Significant gains in such understanding may improve a student's ability to recognize the rigor, legitimacy, and veracity of scientific claims and better discern …

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, …

Stochastic Hybrid Dynamic Systems: Modeling, Estimation And Simulation, Daniel Siu

USF Tampa Graduate Theses and Dissertations

Stochastic hybrid dynamic systems that incorporate both continuous and discrete dynamics have been an area of great interest over the recent years. In view of applications, stochastic hybrid dynamic systems have been employed to diverse fields of studies, such as communication networks, air traffic management, and insurance risk models. The aim of the present study is to investigate properties of some classes of stochastic hybrid dynamic systems.

The class of stochastic hybrid dynamic systems investigated has random jumps driven by a non-homogeneous Poisson process and deterministic jumps triggered by hitting the boundary. Its real-valued continuous dynamic between jumps is described …

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

USF Tampa Graduate Theses and Dissertations

Language and culture teaching has always been a complex and challenging task. For many educators, their teaching experiences are rooted in their earlier preparation, their classroom situations and their curriculum. In this study, indigenous educators recount their lived experiences with teaching their language and culture at a distance. These educators belong to either Nahua or Mayan speech communities where endangered languages are maintained. Using a transcendental phenomenological approach, my participants described and explained their perspectives and experiences with teaching, studying, and integrating technology. I focused the interviews, the reflective writing tasks and their artifact sharing on their experiences in an …

"Are We Supposed To Be The Guy On The Horse?" A Case Study On The Use Of Political Cartoons In The American History Classroom, James Manuel Duran

USF Tampa Graduate Theses and Dissertations

Recent reports on the media saturation experienced by the twenty-first century student have brought about an increased interest in focusing attention on the issue of visual literacy in today's schools. Concepts such as instructional personalization, where approaches to curriculum design and instruction are created to concentrate on the individual strengths of the learner, have been promoted by some as a path to improving overall student performance. Many believe that the content of the Social Studies classroom easily lends itself to a visually stimulating approach and as such is an ideal laboratory to test hypotheses on such an approach. This study …

The relative distribution of metaphors among categories is provided. Using an open coding process, emergent metaphor categories are identified. The qualitative findings describe metaphors and schemas that were potentially activated by particular metaphorical phrases in this context. Lastly, this …

A Fault-Tolerant Alternative To Lockstep Triple Modular Redundancy, Andrew Lockett Baldwin

Dissertations and Theses

Semiconductor manufacturing defects adversely affect yield and reliability. Manufacturers expend vast resources to reduce defects within their processes. As the minimum feature size get smaller, defects become increasingly difficult to prevent. Defects can change the behavior of a logic circuit resulting in a fault. Manufacturers and designers may improve yield, reliability, and profitability by using design techniques that make products robust even in the presence of faults. Triple modular redundancy (TMR) is a fault tolerant technique commonly used to mask faults using voting outcomes from three processing elements (PE). TMR is effective at masking errors as long as no more …

The Role Of Compliment Topics In Compliment Response, Hiroko Katsuta

Dissertations and Theses

This study examines the role of compliment topic by analyzing compliment responses by Japanese and American college students. Compliment responses can be seen as solutions for maintaining a balance between (1) a preference to avoid self-praise and (2) a preference to accept or agree with the compliment (Pomerantz 1978). Building on studies showing that response strategies can be influenced by compliment content and context, the study analyzed responses to compliments on ability, achievement, belongings, appearance, and personal characteristics by determining the subjects' choice of response strategy--categorized as acceptance, avoidance, or rejection--for each compliment topic. Compliment responses were elicited in a …

Climate Change Effects And Water Vulnerability In The Molalla Pudding River Basin, Oregon, Usa, Susan Amelia Wherry

Dissertations and Theses

Water management plans are typically developed using historical data records and historical return periods for extreme events, such as floods or droughts. Since these analyses of return periods typically assume a certain degree of stationarity (constant mean, standard deviation, distribution) in hydrologic variables, the potential future impacts of climate change are excluded. In developing water management plans, predicted changes to climate variables should be considered to evaluate the degree of non-stationarity that may exist in the future. In this way, regions most sensitive to climate change can be identified and managed appropriately. This study performed such a task by using …
