Using Self-Monitoring And Goal Setting To Increase Swimming In Adults, Sarah Rose Abraham

USF Tampa Graduate Theses and Dissertations

Many people in the United States do not engage in the recommended levels of physical activity. Self-management strategies, including self-monitoring and goal setting, are among the interventions that have been used to increase physical activity in adults. Visual feedback has also been incorporated into interventions to increase physical activity. Minimal research has focused on increasing swimming behavior. The current study investigated the effectiveness of self-management strategies to increase swimming activity in adults. An automated recording device (watch) was used to collect data on participants’ swimming behavior. The effect of self-monitoring in the form of a self-graphing intervention to increase swimming …

Are Customers Ready For Tablet-Based Menus? An Analysis Of The Innovation Characteristics That Influence The Intentions To Adopt Tablet-Based Menus, Nataly Suarez

USF Tampa Graduate Theses and Dissertations

Since the release of the new iPad in 2010, few studies have explored the idea of tablet- based menus in restaurants. Since this is a new topic in the hospitality industry, there has not been literature that explores how personal traits influence the adoption intention of tablet-based menus. This study aims to explain the impact of innovation characteristics and individual differences on customer intentions to adopt tablet-based menus in restaurants of different service levels. With a random sample of 430 participants collected via Amazon’s Mechanical Turk, a regression analysis and an ANOVA test were performed. The results confirmed that only …

Mechanical Properties Of Laser-Sintered-Nylon Diamond Lattices, Clayton Neff

USF Tampa Graduate Theses and Dissertations

Additive manufacturing offers a manufacturing technique to produce complex geometry prototypes at a rapid pace and low cost. These advantages advocate additive manufacturing for the design and production of cellular structures. Cellular structures are interesting because they contain a large amount of porosity (void space of air) to manifest a lightweight structure. Designs of cellular structures generate a periodic pattern; often of complex geometry, called a lattice.

There has been a significant amount of research to maximize specific stiffness of lattice structures but little to evaluate low-stiffness lattices. Low-stiffness structures benefit energy absorbance through bending of the lattice. This research …

The Us Response To Genocide In Rwanda: A Reassessment, Camara Silver

USF Tampa Graduate Theses and Dissertations

This thesis analyzes the US response to the 1994 Rwandan genocide. It argues that in 1994, the US was retooling its stance on humanitarian intervention because of the disastrous US-led Operation Gothic Serpent in Somalia in 1993. Therefore, the American response to the genocide in Rwanda became a casualty of Washington’s reassessment of its humanitarian intervention policy in the 1990s. The reason behind the US adoption of a more muscular humanitarian intervention policy was due in part to the end of the Cold War in 1991. Thus, the US was able to focus on other issues in international affairs, such …

Reconstructing Paleoenvironments Of The Plio-Pleistocene Tamiami Formation Of Florida With Benthic Foraminifera, Heather Bender

USF Tampa Graduate Theses and Dissertations

There is general agreement that a range of paleodepths and environments are represented in the individual shell units of the middle Pliocene to earliest Pleistocene Tamiami Formation of southwest Florida, but maximum depths remain poorly constrained. Here, benthic Foraminifera abundances are used as a paleoenvironmental proxy to compare the upper Tamiami from quarries in Sarasota, Florida to Recent modern coastal, bay, and reef habitats of Florida, the Grand Cayman Islands, and Puerto Rico, ranging in depth from 0 to 55 meters. I used: (1) ordination techniques, including detrended correspondence analysis (DCA) and cluster analysis, to compare upper Tamiami foraminiferal assemblages …

Development And Application Of Web-Based Open Source Drug Discovery Platforms, Yuri Pevzner

USF Tampa Graduate Theses and Dissertations

Computational modeling approaches have lately been earning their place as viable tools in drug discovery. Research efforts more often include computational component and the usage of the scientific software is commonplace at more stages of the drug discovery pipeline. However, as software takes on more responsibility and the computational methods grow more involved, the gap grows between research entities that have the means to maintain the necessary computational infrastructure and those that lack the technical expertise or financial means to obtain and include computational component in their scientific efforts. To fill this gap and to meet the need of many, …

Use Of Assessments In College Chemistry Courses: Examining Students' Prior Conceptual Knowledge, Chemistry Self-Efficacy, And Attitude, Sachel M. Villafañe-García

USF Tampa Graduate Theses and Dissertations

Students' retention in STEM-related careers is of great concern for educators and researchers, especially the retention of underrepresented groups such as females, Hispanics, and Blacks in these careers. Therefore it is important to study factors that could potentially influence students' decision to stay in STEM. The work described in this dissertation involved three research studies where assessments have been used in college chemistry courses to assess students' prior content knowledge, chemistry-self-efficacy, and attitude toward science. These three factors have been suggested to have an influence on students' performance in a course and could eventually be a retention factor.

The first …

An Evaluation Of The Utah First District Mental Health Court: Gauging The Efficacy Of Diverting Offenders Suffering With Serious Mental Illness, Stephen Guy Vangeem

USF Tampa Graduate Theses and Dissertations

The decision to establish a mental health court in Utah's First District was largely a political one prompted by the growing popularity of problem-solving courts throughout the country. Because this motivation was policy-driven and not needs-driven, the court was established without an ongoing data collection schedule. As a result, barring anecdotal evidence from program participants, the current impact of the court on two key goals-- reducing recidivism and increasing community-based treatment contact--is entirely unknown. The current study aims to provide a summative program evaluation of the first sixty-eight months of specialty court operation by (1) estimating basic demographic and clinical …

"It Takes Time To Shift Historical Paradigms": Changes In Structure, Governance, Perception, And Practice During A Decade Of Child Welfare Policy Reform In Florida, Amy Catherine Vargo

USF Tampa Graduate Theses and Dissertations

This dissertation explored changes in structure, governance, perception and practice within Florida's child welfare system over a ten-year period (2001-2011) inclusive of two concurrent, statewide reform efforts: the privatization of child welfare services and implementation of a Title IV-E Waiver Demonstration. Using an anthropological perspective and holistic approach, the child welfare system is presented as a type of meta-organizational culture inclusive of subsystems and subcultures which are all embedded in historical and socioeconomic context that involves alternations between child safety and family preservation approaches to care.

Guided by a grounded theory approach to qualitative data analysis, content analysis of child …

Teachers have been provided with a tremendous amount of technology related tools to educate their students. However, many of these technologically enhanced tools have little to no research supporting their claims to enhance learning.

This study focuses on one aspect of technology, the iBook, to complete homework relating to fractions, decimals, and percents in a sixth grade classroom. An iBook is a digital textbook that allows the user to interact with the …

Designing Together With The World Café: Inviting Community Ideas For An Idea Zone In A Science Center, William Travis Thompson

USF Tampa Graduate Theses and Dissertations

This dissertation brings attention to the communication processes taking place during design of an Idea Zone at a science center. It focuses on the conceptual phase of design, during which designers seek to integrate the ideas and needs of stakeholders into design processes through such frameworks as Participatory Design (PD). In bringing a focus on communication process to conceptual design frameworks such as PD, I explore the assumed roles behind participatory design processes and the contexts created through those processes during actual design work. As these Idea Zone design efforts took place in a museum and also within the context …

Teaching About Race In Introductory Anthropology Courses: An Ethnographic Study, Jennifer Gilroy Hunsecker

USF Tampa Graduate Theses and Dissertations

American anthropology has focused on issues related to race from the start of the discipline. From past work designed to categorize humans into phenotype-based categories to current work to undo those categorizations, many anthropologists consider race to be one of the most important topics for students to learn. In this dissertation, I use in-depth ethnographic case studies consisting of interviews, observations, and focus groups, to learn about the way in which anthropologists at four institutions of higher education teach the topic to students in their introductory, four-field general anthropology class. I found that anthropologists are committed to sharing anthropological perspectives …

Clinical And Criminal Justice Outcomes In The Jail Diversion And Trauma Recovery (Jdtr) Program, Daniel Harold Ringhoff

USF Tampa Graduate Theses and Dissertations

This mixed methods study evaluated clinical and criminal justice outcomes of the Florida Jail Diversion and Trauma Recovery (JDTR) program that utilized compensated veteran peer mentors. Quantitative results showed veteran participation in JDTR improved clinical outcomes, such as PTSD symptoms, function difficulty and depression scores, but not criminal justice outcomes such as re-arrest rates. Study limitations, however, prevent the drawing of conclusions regarding the potential effectiveness of veteran peer interventions improving criminal justice outcomes. Qualitative results showed participants overwhelmingly viewed their assigned veteran peer mentor as a "peer" and rated them as "very important" to their future success. Improvements in …

Examining Experiences Of Early Intervention Providers Serving Culturally Diverse Families: A Multiple Case Study Analysis, Wendy Lea Bradshaw

USF Tampa Graduate Theses and Dissertations

The cultural and linguistic diversity of the United States is growing rapidly and early intervention service providers are very likely to work with families whose cultures differ from their own. Service providers must consider the multiple cultural factors of families which contribute to family dynamics and the potential for miscommunication is high when the cultural frameworks of early intervention providers differ from those of the families they serve. Culturally responsive practices have been put forth in the theoretical literature as a way to increase successful communication and service provision but there is limited research investigating the beliefs, experiences, and practices …

Precalculus Students' Achievement When Learning Functions: Influences Of Opportunity To Learn And Technology From A University Of Chicago School Mathematics Project Study, Laura A. Hauser

USF Tampa Graduate Theses and Dissertations

The concept of function is one of the essential topics in the teaching and learning of secondary mathematics because of the central and unifying role it plays within secondary and college level mathematics. Organizations, such as the National Council of Teachers of Mathematics, suggest students should be able to make connections across multiple representations of mathematical functions by the time they complete high school. Despite the prominent role functions play in secondary mathematics curriculum, students continue to struggle with the complex notion of functions and especially have difficulty using the different representations that are inherent to functions (algebraic, graphical and …

The Impact Of Bus Rapid Transit Implementation On Residential Property Values: A Case Study In Reno, Nv, Steven Thomas Ulloa

USF Tampa Graduate Theses and Dissertations

Since literature that evaluates the impacts that Bus Rapid Transit (BRT) has on surrounding property values is limited, this research contributes to this research by investigating if proximity to a BRT station has an effect, either positive or negative, on residential housing values. Further, it investigates if the nature and extent of this effect varied during different stages of implementation of the BRT system and different housing market conditions. Fluctuations in sale prices were mitigated based on a six month moving median. Four hedonic price models were then used to evaluate the influence of independent variables on the dependent variable, …

Engaging-Up: Compromised Spaces And Potential Partners, Jennifer Necole Webb

USF Tampa Graduate Theses and Dissertations

The anthropology of public policy critically examines policy and its processes and the myriad ways in which power is exercised. To explore these power dynamics, anthropologists studying policy often study up, or study through a particular policy field. This entails the risky work of studying powerful people, whose ability to retaliate against the researcher and others create methodological and ethical dilemmas and contradictions, as well as potentially harmful consequences. Politicians, bureaucrats, employees of powerful non-profits, and, in the public-private neoliberal reality, even the head decision makers within corporations are all prospective research participants--an intimidating prospect for most anthropologists. In contrast, …

"I Want To Be The Sun": Tableau As An Embodied Representation Of Main Ideas In Science Information Texts, Margaret Branscombe

USF Tampa Graduate Theses and Dissertations

In this study I investigated the process drama convention of tableau to mediate for the representation of main ideas in science information texts. My pedagogical goal was to focus on the body as a tool for engaging with information texts and my rationale for this goal was the belief that the body is neglected in classroom learning. The task of creating caused the students to be active and to think of their own and other bodies as signifiers of meaning.

The methodology was based on a formative experiment that allowed for changes and modifications to be made in response to …

Using Acoustical Feedback To Improve Elementary School Student Behavior During Transitions, Lauren Danielle Altman

USF Tampa Graduate Theses and Dissertations

Behavior during transitions in classrooms is an area in need of additional supports in order for teachers to effectively manage classrooms. Extended transition durations, particularly transition periods between one activity and another are related to problem behavior among children in educational settings. This study evaluated the use of acoustical feedback aimed to improve transition behaviors of elementary school students, using a multiple-baseline design across participants. Teachers were trained to implement the acoustical feedback procedure. Data on teacher treatment fidelity, student transition behavior (transition duration and problem behavior), generalization probes, and social validity were collected to examine the feasibility and potential …

Creating A Professional Pathway For The Women Who Care For Our Children: An Anthropological Study Of An Early Childhood Workforce Development Policy, Melissa Kay Van Dyke

USF Tampa Graduate Theses and Dissertations

Historically, the early childhood workforce has been described as undereducated, poor, and disproportionately comprised of women of color. The EDUCATE workforce development policy was designed to advance the professional development of under-paid and under-valued child care workers. This study focuses on the history, intent, and impact of this policy at the intersection between the grantees, the State, the various organizational contexts, and the broader structural forces. More broadly, complex issues and challenges related to the early childhood workforce are surfaced. Finally, through a critical analysis of the findings, the hidden and dominating forces that maintain the current level of inequity …

Psychopathy And Perception Of Vulnerability, Barbara Joyce Dinkins

USF Tampa Graduate Theses and Dissertations

Prior research has shown that psychopathic traits correlate with ability to make more accurate assessments of vulnerability based on nonverbal cues (Wheeler, Book, & Costello, 2009; Book, Costello, & Camilleri, 2013). The current study aims to provide further support for this finding, examine effect of criminal experience, and determine if the finding generalizes to females and non-Caucasians. An online survey was conducted, where each participant was shown several videos of people walking alone down a hallway. After each video, they were asked to rate the vulnerability of the depicted person. Higher levels of psychopathic traits (measured by the Elemental Psychopathy …

Acquisition And Generalization Of Tacts Across Stimulus Modes In Children Diagnosed With Autism Spectrum Disorder, Luz Elena Correa Gómez

USF Tampa Graduate Theses and Dissertations

This study evaluated the speed of acquisition and level of generalization of tacts across three different stimulus modes: picture-flashcard, video clip, and 3D object. Three young children diagnosed with autism participated in this study. The acquisition of tacts was evaluated during Discrete Trial Training sessions (DTT). Two of the three participants learned the tacts more rapidly in the video clip condition in contrast with the picture condition. All three participants generalized the three tacts learned through a specific stimulus mode to the remaining stimulus modes. One week after the generalization test, all participants generalized to all novel 3D objects.

Interpretations Of Educational Experiences Of Women In Chitral, Pakistan, Rakshinda Shah

USF Tampa Graduate Theses and Dissertations

This feminist oral history project records, interprets, and analyzes the educational experiences of seven Ismaili college women in Chitral, Pakistan. Chitral is a part of the world where educating girls and women is not a priority. Yet in the scarce literature available one can observe an increase in the literacy rates, especially amongst the Ismaili Muslims in the North of Chitral District. This thesis introduces students' accounts of their personal educational journeys. I argue that the students' accounts exemplify third space feminism. They negotiate contradictions and social invisibility in their daily lives in quiet activism that shadows but changes the …

Low-Power And Robust Level-Shifter With Contention Mitigation For Memory And Standalone Applications, Kenneth M. Ramclam

USF Tampa Graduate Theses and Dissertations

The scaling down of transistor sizes has imposed significant challenges in today's technology. Memories such as eDRAM, are experiencing poor retention time because of challenges such as reference voltage variation, high transistor leakage, and low cell capacitance. It can be seen that we must consider not only the first order effects, but also the second order effects to ensure we keep up with current technology trends such as Moore's law. In this thesis we explore various circuit level techniques on level shifters in order to achieve better retention time. With our research, we have addressed important design challenges and propose …

On The Selection Of Just-In-Time Interventions, Luis Gabriel Jaimes

USF Tampa Graduate Theses and Dissertations

A deeper understanding of human physiology, combined with improvements in sensing technologies, is fulfilling the vision of affective computing, where applications monitor and react to changes in affect. Further, the proliferation of commodity mobile devices is extending these applications into the natural environment, where they become a pervasive part of our daily lives. This work examines one such pervasive affective computing application with significant implications for long-term health and quality of life adaptive just-in-time interventions (AJITIs). We discuss fundamental components needed to design AJITIs based for one kind of affective data, namely stress. Chronic stress has significant long-term behavioral and …

Using Awareness Training To Decrease Nervous Habits In Public Speaking, Claire Spieler

USF Tampa Graduate Theses and Dissertations

Research on components of habit reversal suggests that awareness training alone may be an effective and efficient intervention for reducing nervous habits. This study evaluated the effectiveness of awareness training for the reduction of three nervous habits that manifest in public speaking: filled pauses, tongue clicks, and inappropriate use of the word "like." Four university students delivered short speeches during baseline and assessment sessions. Awareness training consisted of response description and response detection. Awareness training resulted in meaningful reductions in target behaviors for all participants. Booster awareness training sessions were necessary for all participants to achieve further reductions in target …
