Sulk Localization And Topology Control In Large Scale Heterogeneous Wireless Sensor Networks, Rui Zhang
Sulk Localization And Topology Control In Large Scale Heterogeneous Wireless Sensor Networks, Rui Zhang
USF Tampa Graduate Theses and Dissertations
Wireless Sensor Networks (WSNs) continue to evolve as new applications emerge. In the recent past, WSNs were mostly single sink networks with a few number of homogeneous and static sensor nodes. Now, several applications require networks with multiple and moving sinks and targets as well as thousands of heterogeneous devices. However, the same constraints remain: sensor nodes continue to be very limited in resources, posing new challenges in the design of scalable and energy-efficient algorithms and communication protocols to support these new applications. This dissertation first addresses the problem of sink localization in large scale WSNs. A scalable and energy-efficient …
Community Context And Health Disparities Among Older Adults, Helen M. Zayac
Community Context And Health Disparities Among Older Adults, Helen M. Zayac
USF Tampa Graduate Theses and Dissertations
African Americans, Hispanics, and other minorities in the U.S. continue to face conditions of residential and educational segregation, lower socioeconomic status, and higher rates of mortality than whites. Better theory-based research that uses community and individual level factors to explain how health disparities are created and perpetuated is needed. The Community Context and Health Disparities Model, which extends the work of Schulz and Northridge (2004) with elements described by Williams and Collins (2001), is described. This framework identifies the pathways by which characteristics of the physical, built, social, economic, and healthcare environments impact health and are mediated by individual traits. …

Breaking The Typecast: Revising Roles For Coordinating Mixed Teams, Matthew T. Long
USF Tampa Graduate Theses and Dissertations
Heterogeneous multi-agent systems are currently used in a wide variety of situations, including search and rescue, military applications, and off-world exploration, however it is difficult to understand the actions of these systems or naturalistically assign these mixed teams to tasks. These agents, which may be human, robot or software, have different capabilities but will need to coordinate effectively with humans in order to operate. The first and largest contributing factor to this challenge is the processing, understanding and representing of elements of the natural world in a manner that can be utilized by artificial agents. A second contributing factor is …

Analysis Of Vtol Mav Use During Rescue And Recovery Operations Following Hurricane Katrina, Kevin S. Pratt
USF Tampa Graduate Theses and Dissertations
There can be little doubt that Hurricane Katrina will always be remembered for the damage and devastation it caused. But it also provided the first opportunity for MAVs to be used and evaluated during Search and Rescue (SAR) as well as recovery operations. Researchers from The Center for Robot-Assisted Search And Rescue (CRASAR) made two separate deployments to areas affected by Hurricane Katrina: one during initial SAR operations and a second deployment during recovery operations 90 days later. Using data and observations from both of these deployments, this work draws four key findings about semi-autonomous Miniature UAV (MAV) operations in …
Design And Evaluation Of New Search Paradigms And Power Management For Peer-To-Peer File Sharing, Graciela Perera
Design And Evaluation Of New Search Paradigms And Power Management For Peer-To-Peer File Sharing, Graciela Perera
USF Tampa Graduate Theses and Dissertations
Current estimates are that more than nine million PCs in the U.S. are part of peer-to-peer (P2P) file sharing overlay networks on the Internet. These P2P hosts generate about 20% of the traffic on the Internet and consume about 7.8 TWh/yr equal to $630 million per year. File search in a P2P network is based on a wasteful paradigm of broadcasting query messages. Reducing P2P overhead traffic to reduce bandwidth waste and enabling power management to reduce electricity usage are clearly of great interest. In this dissertation, two new search paradigms with reduced overhead traffic are investigated. The new Targeted …

Defining Service Quality In An Outpatient Clinic With Complex Constituency, Swati Verma
Defining Service Quality In An Outpatient Clinic With Complex Constituency, Swati Verma
USF Tampa Graduate Theses and Dissertations
The 2001 Institute of Medicine's (I.O.M.) landmark report, Crossing the Quality Chasm: A New Health System for the 21st Century observes that, "[though] medical science and technology have advanced at a rapid pace,...the health care delivery system has floundered in its ability to provide consistently high-quality care" (I.O.M. 2001). The report recommended six quality aims for a twenty-first century health care system; one of them being patient-centered care. It explains patient-centered care as "providing care that is respectful of and responsive to individual patient preferences, needs, and values and ensuring that patient values guide all clinical decisions" (I.O.M. 2001).

The Conditional Influence Of Criminological Constructs On Juvenile Delinquency: An Examination Of The Moderating Effects Of Self-Control, Angela Yarbrough
The Conditional Influence Of Criminological Constructs On Juvenile Delinquency: An Examination Of The Moderating Effects Of Self-Control, Angela Yarbrough
USF Tampa Graduate Theses and Dissertations
Self-control and various elements comprising this construct have received much credit over the years as it has been able to account for a large amount of variance in delinquency rates. Some research has suggested that individual difference factors (e.g., self-control) can overwhelm external factors (e.g., neighborhoods; see Loeber & Wikström, 2000). Others have found that social influences (e.g., employment; see Wright, et al, 2001) have more pronounced effects for those most at-risk. Because of the equivocal nature of the empirical findings, this study seeks to replicate and extend previous efforts. Specifically, the influence of constructs derived from social learning, control, …

The system described in this thesis will allow first responders to practice on the robots without …
Fabrication: Corporate And Governmental Crime In The Apparel Industry, Danielle Mcgurrin
Fabrication: Corporate And Governmental Crime In The Apparel Industry, Danielle Mcgurrin
USF Tampa Graduate Theses and Dissertations
The purpose of this dissertation is to examine both the gendered and racialized nature of workplace risk and compensation in the manufacturing industry of apparel. The author selects this industry because of its low-wage, labor intensive, and "deskilled" work, performed in often unsafe employment environments with minimal governmental regulations and limited unionization. The apparel industry is also characterized by its large percentage of racial and ethnic minorities, especially immigrant employees, that further disadvantage them in terms of communication barriers, threat of deportation, and the multiple and intersecting marginalizations associated with occupying a low-wage, minority and/or immigrant status. The gendered effects …
Barium Strontium Titanate Films For Tunable Microwave And Acoustic Wave Applications, Venkataramanan Gurumurthy
Barium Strontium Titanate Films For Tunable Microwave And Acoustic Wave Applications, Venkataramanan Gurumurthy
USF Tampa Graduate Theses and Dissertations
The composition-dependent Curie temperature and bias-dependant dielectric permittivity of Barium Strontium Titanate (BST) makes it very attractive for tunable application in the RF/Microwave regime. In this research work, the performance of BST varactors fabricated on the conventional Pt/Ti/SiO2/Si bottom electrode stack were compared with those fabricated using chemical vapor deposited Nanocrystalline Diamond (NCD) as the diffusion barrier layer instead of SiO2. The varactors fabricated on NCD films displayed much better symmetry in capacitance-voltage behavior and better overall quality factors than varactors fabricated on SiO2. The improvement in performance can be attributed to existence of stable interfaces in the devices fabricated …

Philosophy Of New Jazz: Reconstructing Adorno, Dustin Bradley Garlitz
Philosophy Of New Jazz: Reconstructing Adorno, Dustin Bradley Garlitz
USF Tampa Graduate Theses and Dissertations
Theodor W. Adorno, the towering twentieth century German intellectual figure and distinctive musical thinker, was legendary for being over-critical of jazz music. Through a consideration at his admiration for avant-garde chamber and symphonic music, I plan to develop a position that, surprisingly, points towards a theory of unacknowledged acceptance of jazz. The style of jazz that will be the newly constructed musical idiom of admiration for Adorno will be of the heterodox variety. My method of reconstruction will be to interrogate the inconsistencies in Adorno's critical musical writings, and negate such negations with factual evidence of affirmation found in the …

Do You See What I Mean? Measuring Consensus Of Agreement And Understanding Of A National Weather Service Informational Graphic, Lorna M. Geggis
USF Tampa Graduate Theses and Dissertations
Media use of hurricane graphics to apprise populations vulnerable to severe weather provides a persuasive demonstration of the importance and complexity of visual communication. Surprisingly little research, however, has explored how audiences interpret weather graphics. This study examined whether the general public and the National Weather Service share a common understanding of selected weather related terms and meaning of a NWS informational graphic. Using a coorientation model, general public responses to a questionnaire were compared to definitions prescribed by the NWS. Additionally, the public were asked questions to measure trust of the NWS as a credible and reliable source of …
The Appeal Of The Underdog: Definition Of The Construct And Implications For The Self, Nadav Goldschmied
The Appeal Of The Underdog: Definition Of The Construct And Implications For The Self, Nadav Goldschmied
USF Tampa Graduate Theses and Dissertations
From politics to sports to business, people are quick to categorize those at a considerable competitive disadvantage as "underdogs." Moreover, there is ample support that most unattached observers do not hesitate to align themselves with underdogs, a phenomenon termed "the underdog effect." While most dictionary definitions state that underdogs are "especially expected to lose," the present investigation argues that people often attribute optimistic qualities to underdogs and the exceeding of expectations. A series of studies was conducted to examine the lay-person definition of what an underdog means, as well as what motivations may play a role in the underdog effect. …
A Paradox Of Diversity: Billions Invested, But Women Still Leave, Rebekah S. Heppner
A Paradox Of Diversity: Billions Invested, But Women Still Leave, Rebekah S. Heppner
USF Tampa Graduate Theses and Dissertations
In 2005, women made up 46.4 percent of the United States labor force but only 1.6 percent of Fortune 500 CEOs (Catalyst 2006). Although gains have been made since the passage of the Civil Rights Act in 1964, there is clearly something stopping women from equal representation at the top. Since the late 1980s, businesses have spent billions of dollars on initiatives designed to assist them in dealing with the anticipated increase in the "diversity" of their workplaces (Lubove 1997; Stodghill II 1996; Johnston and Packer 1987). Is there potential for diversity initiatives to help women conquer the "glass ceiling?" …

The Gothic As Counter-Discourse: Mark Twain, Charles Chesnutt And Toni Morrison, Hyejin, Kim
The Gothic As Counter-Discourse: Mark Twain, Charles Chesnutt And Toni Morrison, Hyejin, Kim
USF Tampa Graduate Theses and Dissertations
Revisiting the American Gothic via Julia Kristeva's theory of "the abject" demonstrates how Gothic strategies expose the historical contradictions of race in works by Mark Twain, Charles W. Chesnutt, and Toni Morrison. As theorized by Kristeva in Powers of Horror, the archaic process in which the subject attempts to constitute itself as homogeneous by casting off or "abjecting" all that cannot be assimilated to the self-same necessarily opens the way to repeated returns of the abject(ed) and the "horror" it provokes. Because the Gothic enacts the return of the abject, it was itself abjected from the literary canon until recently. …
The “Dark Side” Of Ocb: Examining The Relationship Between Citizenship Behavior And Work-To-Family Conflict, Rebecca H. Klein
The “Dark Side” Of Ocb: Examining The Relationship Between Citizenship Behavior And Work-To-Family Conflict, Rebecca H. Klein
USF Tampa Graduate Theses and Dissertations
Research on organizational citizenship behaviors (OCB) has focused on the positive aspects of the construct, neglecting the possibility that individuals who engage in OCB may suffer negative consequences. Thus, the present study expands the literature by examining the possibility that OCB is also related to negative individual-level factors, such as work-to-family conflict (WIF). In a replication and extension of Bolino and Turnley's (2005) research, the present study offers an in-depth analysis of the relationship between OCB and WIF, examining two potential mediators (work time and role overload) and two potential moderators (gender and perceptions of OCB as discretionary). Two hundred …
Meaning Makers Make It: Ambivalence About Ambiguity In Academic Discourse, David Haldane Lee
Meaning Makers Make It: Ambivalence About Ambiguity In Academic Discourse, David Haldane Lee
USF Tampa Graduate Theses and Dissertations
This thesis is a broad survey of the uses of ambiguity in academic discourse. I note the uses of ambiguity in literary criticism, linking ambiguity with epistemic relativism. Then I pose the question, is the notion of "reframing" in psychotherapy analogous to the concept of "spin" in propaganda, advertising and public relations? In a consideration of theories that posit the social construction of reality, I examine articles by Judith Butler and Ian Hacking, noting the ambiguous reception of performativity and nominalism, respectively, within academia. In 1996 a physicist named Alan Sokal published an article which argued that reality is a …
