Help-Seeking And Utilization Patterns Among African American And Caucasian Mothers And Fathers: An Examination Of Parental Problem Recognition, Barriers, And Beliefs, Idia Binitie Thurston 2010 University of South Florida

Help-Seeking And Utilization Patterns Among African American And Caucasian Mothers And Fathers: An Examination Of Parental Problem Recognition, Barriers, And Beliefs, Idia Binitie Thurston

Graduate Theses and Dissertations

The underutilization of mental health services is a pervasive problem that persists despite efforts by researchers and interventionists to make treatment accessible. Several factors have been hypothesized to contribute to these underutilization rates including sociopolitical factors (financial and structural barriers), and cultural/familial factors (race, ethnicity, socioeconomic status, gender, age, marital status, attitudes, beliefs, and stigma). The current study set out to explore patterns of child mental health service utilization based on parents' perceptions. Guided by "The Youth Help-Seeking and Service Utilization Model," the relationship between parental problem recognition and willingness to seek formal and informal help as influenced by ...

Perceptions Of Career And Psychosocial Functions Between Mentor And Protégé Teachers, Allison A. Vanderbilt

Graduate Theses and Dissertations

The purpose of this study was to identify the career and psychosocial functions that mentor teachers and their protégé teachers believed occurred during the 2008-2009 mentoring relationship. This comparative survey study was conducted in a suburban middle-sized Florida school district. The target population for this study involved one group of matched mentor teachers and protégé teachers. Two survey instruments were used during this study, Mentoring Functions Scale for the Mentor and the Mentoring Functions Scale for the Protégé modified by Wilson (2006). This instrument was selected because it measures the career and psychosocial functions of the mentoring process. The survey ...


Perceiving Architecture: A Experiential Design Approach, Ashley Verbanic 2010 University of South Florida

Perceiving Architecture: A Experiential Design Approach, Ashley Verbanic

Graduate Theses and Dissertations

Perception of the physical environment is largely dependent on a range of criteria which are not always readily identifiable. Such a difficulty to identify how a person perceives an environment creates a situation in which architects and designers can easily neglect this idea of the individual user and their experience. Through the design of a preschool, this thesis focuses largely on understanding how children and other users perceive and interact with their environments. The design process employed synthesizes user based research and analysis of environmental cues such as light, sound, and smells and their effect on how we interpret a ...

Exploratory Analysis Of Maintenance In Behavioral Parent Training, Claudia Villari

Graduate Theses and Dissertations

A two-part study explored the maintenance effect of Behavioral Parent Training (BPT) featuring multi-component treatments by examining one year follow-up data from a larger study. Participants were ten parents of children (ages 3-5) with developmental disabilities and severe problem behaviors. Parents were also identified as having high levels of pessimism. BPT featuring multi-component treatments was provided in two conditions: Positive Behavior Support (PBS) and Positive Family Intervention (PFI). PBS included a standardized protocol to teach parents how to conduct a functional assessment, develop and implement a multi-component treatment, which includes the following strategies: prevention, teaching replacement skills, and managing consequences ...


The Accidental Practitioner: Principles Of Rational Emotive Behavior Therapy In The Works Of Kurt Vonnegut, Joseph J. Ward 2010 University of South Florida

The Accidental Practitioner: Principles Of Rational Emotive Behavior Therapy In The Works Of Kurt Vonnegut, Joseph J. Ward

Graduate Theses and Dissertations

Just as psychology and philosophy have influenced the field of literary studies, literature provides insight about the theories and practices of its sister disciplines. The purpose of this thesis is to demonstrate how literary works of Kurt Vonnegut illuminate principles of the influential branch of psychotherapy known as Rational Emotive Behavior Therapy (REBT). This thesis traces the similar philosophies and shared beliefs of Vonnegut and REBT's founder, Albert Ellis, and details how Ellis's REBT is illustrated in selected works of Vonnegut, specifically, Slaughterhouse-Five, Breakfast of Champions, Galapagos, and Timequake. The thesis concludes by suggesting that Vonnegut's works ...


Headline Hawai`I: Racial Aloha In Kama`Aina News, Cory J. Weaver 2010 University of South Florida

Headline Hawai`I: Racial Aloha In Kama`Aina News, Cory J. Weaver

Graduate Theses and Dissertations

The front page of Hawai`i's largest-circulated newspaper - The Honolulu Star-Bulletin - was reviewed for a three-month period: March 1, 2008 - June 1, 2008, to examine representations of race in a media market where Caucasian individuals are the minority. Analysis of the newspaper seeks to present a greater understanding of ethnic portrayals in island news and examines ethical implications that have/can arise from adopting journalistic values typical of "white news" or mainstream reporting practices in areas where the mainstream is, in fact, the minority.

First, members of the nano - carbon family are utilized for biosensing applications; in particular, carbon nanotubes as well as nitrogen - doped and boron - doped nanocrystalline diamond (NCD) films. These carbon - based materials possess several unique electrochemical properties over other conductive materials which make them suitable ...


Victimization Among Individuals With Low Self-Control: Effects On Fear Versus Perceived Risk Of Crime, Casey Williams 2010 University of South Florida

Victimization Among Individuals With Low Self-Control: Effects On Fear Versus Perceived Risk Of Crime, Casey Williams

Graduate Theses and Dissertations

Fear of crime is an issue that has long been a part of mainstream society through politics and media. However, research on the specific mechanisms of fear and the effects on behavior is sparse. After considering the victim-offender overlap consistently found within the literature, the present study was based on the theory posed within Schreck, Stewart, and Fisher (2006) in which those who are low in self-control may have altered perceptions of fear or risk of crime that might increase the likelihood that the individual will be in risky locations conducive to victimization. The current study also included a novel ...

Increasing Healthy Food Choices In Preschoolers Using Correspondence Training And Recruiting Natural Communities Of Reinforcement, Elyse D. Wiseman

Graduate Theses and Dissertations

Obesity is a contributing factor to many diseases. Unhealthy food choices are a behavior that can lead to obesity. Teaching children to make healthy food choices at an early age could lead to healthy food choices throughout a lifetime, which would mitigate potential for obesity. A number of different treatments have evaluated healthy food choices in children; however, many did not evaluate or show maintenance effects. The purpose of this study was to utilize correspondence training to acquire healthy food choices in preschoolers and to evaluate of natural communities of reinforcement as a maintenance procedure. Results showed that correspondence training ...

To What Extent Does A Social Compact Exist Between Higher Education And Society: A Study Of Two Minnesota Universities, Laurie Woodward

Graduate Theses and Dissertations

This dissertation explores the nature, applicability and usefulness of social contract theory, and the resulting compact between higher education and society as a way to understand the growth and development of higher education in the United States. The goal is accomplished with an in-depth look at two different universities in the state of Minnesota at four different periods or pivotal points in the history of higher education in the United States. The underlying assumption was that if there is a social compact between higher education and society, traces of its existence would be found in the historical evidence concerning the ...


Development Of Uhf Micromechanical Resonators And Arrays Based On Silicon-On-Insulator (Soi) Technology, Mingke Xiong 2010 University of South Florida

Development Of Uhf Micromechanical Resonators And Arrays Based On Silicon-On-Insulator (Soi) Technology, Mingke Xiong

Graduate Theses and Dissertations

A novel micromachining technology on SOI substrates is presented that is capable of producing on-chip high-Q resonators and resonator arrays equipped with high aspect-ratio (30:1) microstructures and nano-gap capacitive transducers filled with high-k dielectrics. The newly developed IC-compatible MEMS microfabrication process consists of merely three standard photolithography steps, which is much simpler than the other SOI-based resonator device technologies. In order to achieve the optimum performance and yield of the resonators and resonator arrays, this SOI-based fabrication process has been carefully designed and investigated step by step. For capacitively-transduced extensional mode (e.g., radial-contour and wine-glass mode) resonators, formation ...


Two Essays On Information Ambiguity And Informed Traders' Trade-Size Choice, Ziwei Xu 2010 University of South Florida

Two Essays On Information Ambiguity And Informed Traders' Trade-Size Choice, Ziwei Xu

Graduate Theses and Dissertations

Defining ambiguity as investor's uncertainty about the precision of the observed information, Chapter One constructs an empirical measure of ambiguity based on analysts' earnings forecast information, and finds that the market tends to react more negatively to highly ambiguous bad news, while it tends to be less responsive to highly ambiguous good news. This result supports the theoretical argument of Epstein and Schneider (2003, 2008) that ambiguity-averse investors take a worst-case assessment of the information precision, when they are uncertain about the information precision. In addition, Chapter One shows that returns on stocks exposed to highly ambiguous and intangible ...


The Fanconi Anemia (Fa/Brca Dna Damage Repair Pathway Is Reglated By Nf-[Kappa]B And Mediates Drug Resistance In Multiple Myeloma, Danielle N. Yarde 2010 University of South Florida

The Fanconi Anemia (Fa/Brca Dna Damage Repair Pathway Is Reglated By Nf-[Kappa]B And Mediates Drug Resistance In Multiple Myeloma, Danielle N. Yarde

Graduate Theses and Dissertations

The Fanconi Anemia (FA)/BRCA DNA damage repair pathway plays a critical role in the cellular response to stress induced by DNA alkylating agents and greatly influences drug response in cancer treatment. We recently reported that FA/BRCA DNA damage repair pathway genes are overexpressed and causative for resistance in multiple myeloma (MM) cell lines selected for resistance to melphalan. We hypothesized that the FA/BRCA DNA damage repair pathway mediates response and resistance to chemotherapeutic agents used to treat multiple myeloma and other cancers, and targeting this pathway is vital to overcoming drug resistance. In this dissertation, we show ...


On The Involvement Of The Low-Density Lipoprotein Receptor In The Pathogenesis And Progression Of Alzheimer's Disease, Jose Francisco Abisambra Socarras 2010 University of South Florida

On The Involvement Of The Low-Density Lipoprotein Receptor In The Pathogenesis And Progression Of Alzheimer's Disease, Jose Francisco Abisambra Socarras

Graduate Theses and Dissertations

Alzheimer's disease (AD) is the most prevalent form of age-associated dementia. Cholesterol dysregulation is linked with AD onset. Besides age, the most important risk factor associated with AD is the inheritance of the epsilon-4 allele of apolipoprotein E, a cholesterol transporter. In addition, while hypercholesterolemia has been shown to be an independent risk factor for AD, the nature of the cholesterol-AD link is still not clear. This gap in our understanding is partly due to a lack of knowledge about cholesterol metabolism in the central nervous system (CNS). The low-density lipoprotein receptor (LDLR) is the main receptor of apoE ...


Geos: A Service For The Management Of Geo-Social Information In A Distributed System, Paul Anderson 2010 University of South Florida

Geos: A Service For The Management Of Geo-Social Information In A Distributed System, Paul Anderson

Graduate Theses and Dissertations

Applications and services that take advantage of social data usually infer social relationships using information produced only within their own context, using a greatly simplified representation of users' social data. We propose to combine social information from multiple sources into a directed and weighted social multigraph in order to enable novel socially-aware applications and services. We present GeoS, a geo-social data management service which implements a representative set of social inferences and can run on a decentralized system. We demonstrate GeoS' potential for social applications on a collection of social data that combines collocation information and Facebook friendship declarations from ...


Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn 2010 University of South Florida

Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn

Graduate Theses and Dissertations

IT equipment has been estimated to be responsible for 2% of global CO2 emissions and data centers are responsible for 1.2% of U.S. energy consumption. With the large quantity of high quality digital content available on the Internet the energy demands and environmental impact of the data centers must be addressed. The use of peer-to-peer technologies, such as BitTorrent, to distribute legal content to consumers is actively being explored as a means of reducing both file download times and the energy consumption of data centers. This approach pushes the energy use out of the data centers and into ...


Founding Fathers: An Ethnic And Gender Study Of The Iliadic Aeneid, Rob Brannon 2010 University of South Florida

Founding Fathers: An Ethnic And Gender Study Of The Iliadic Aeneid, Rob Brannon

Graduate Theses and Dissertations

In a 2005 work, Yasmin Syed concluded that the Aeneid created for ancient readers an idea of Romanness that was inclusive for all and not founded along strict genetic lines. Under this hypothesis, the Aeneid offers a sort of blueprint for becoming Roman, one in which biological descent from Aeneas is unnecessary. Syed reached this conclusion by analyzing themes of ethnicity and gender, in particular the ethnic other represented by the epic's female characters. This was accomplished in the manner so often chosen by Vergil scholars-by limiting analysis to the first half of the epic. The work concludes with ...


Alien Encounters And The Alien/Human Dichotomy In Stanley Kubrick's 2001, A Space Odyssey And Andrei Tarkovsky's Solaris, Keith Cavedo 2010 University of South Florida

Alien Encounters And The Alien/Human Dichotomy In Stanley Kubrick's 2001, A Space Odyssey And Andrei Tarkovsky's Solaris, Keith Cavedo

Graduate Theses and Dissertations

The alien encounter has long been a defining and popular subject of science fiction cinema. However, Stanley Kubrick's 2001: A Space Odyssey (1968) and Andrei Tarkovsky's Solaris (1972) are interrogative, complex, and distinct artistic accomplishments that stand apart from and above the conventional science fiction film. 2001 and Solaris not only represent but complicate the alien/human dichotomy; in the end, they destabilize the dichotomy and even suggest a radical synthesis of the dichotomous elements. 2001 and Solaris further emphasize epistemological and specifically anthropocentric limitations when it comes to understanding the alien or attempting to make sense of ...


Residual Stress Analysis In 3c-Sic Thin Films By Substrate Curvature Method, Jose M. Carballo 2010 University of South Florida

Residual Stress Analysis In 3c-Sic Thin Films By Substrate Curvature Method, Jose M. Carballo

Graduate Theses and Dissertations

Development of thin films has allowed for important improvements in optical, electronic and electromechanical devices within micrometer length scales. In order to grow thin films, there exist a wide variety of deposition techniques, as each technique offers a unique set of advantages. The main challenge of thin film deposition is to reach smallest possible dimensions, while achieving mechanical stability during operating conditions (including extreme temperatures and external forces, complex film structures and device configurations). Silicon carbide (SiC) is attractive for its resistance to harsh environments, and the potential it offers to improve performance in several microelectronic, micro-electromechanical, and optoelectronic applications ...
