Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver Jan 2011

Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …


Catalytic Hydrodehalogenation And Hydrogenation Of Halogenated Aromatic Organic Contaminants For Application To Soil Remediation, Claire J. Osborn Jan 2011

Catalytic Hydrodehalogenation And Hydrogenation Of Halogenated Aromatic Organic Contaminants For Application To Soil Remediation, Claire J. Osborn

USF Tampa Graduate Theses and Dissertations

The objective of this research was to aid in the development of a new method for removing and destroying soil contaminants. In particular, 1,2,4,5-tetrachlorobenzene (TeCB) was selected for this research. Hydrodehalogenation (HDH) was paired with hydrogenation for remedially destroying TeCB without generating a secondary waste stream in a single batch reactor. Palladium- and rhodium-catalyzed HDH and hydrogenation were applied in a batch reactor at room temperature and moderate hydrogen pressure. Cyclohexane was formed as an end product with benzene as an intermediate reactant.

An analytical method was developed to measure TeCB, benzene, and cyclohexane in a solution of water and …

Perceptions On Collaborative Learning: A Case Study Of Female Community College Instructors, Marilyn Christine Armstrong Jan 2011

Perceptions On Collaborative Learning: A Case Study Of Female Community College Instructors, Marilyn Christine Armstrong

USF Tampa Graduate Theses and Dissertations

In the 1980s, academic assessments called for "the ability of individuals and groups to talk, listen judge, and act on issues of common interest" (Morse, 1989, p. 30). More recently, corporate research findings, Are They Ready to Work? Employers' Perspectives on the Basic Knowledge and Applied Skills of New Entrants to the 21st Century U.S. Workforce (The Conference Board, Inc., Partnership for 21st Century Skills, The Corporate Voices for Working Families, & Society for Human Resource Management, 2006), report the workplace is seeking college graduates with skill in collaboration (e.g. build diverse relationships, negotiate, manage conflict). While the interest in …


Giving Meaning To Grief: The Role Of Rituals And Stories In Coping With Sudden Family Loss, Julia Janelle Barnhill Jan 2011

Giving Meaning To Grief: The Role Of Rituals And Stories In Coping With Sudden Family Loss, Julia Janelle Barnhill

USF Tampa Graduate Theses and Dissertations

In this dissertation, I seek to better understand the sensemaking process among surviving family members after a tragic loss of a teenage or young adult child. Using social constructionism (Gergen, 1991) as a theoretical framework, I focused on how meanings of loss are constructed through the use of language and other symbols. I specifically looked at the role of family stories and rituals in making sense of the sudden loss as well as how a survivor's role as a sibling or parent may impact the grieving process. The participants in my research were all members of families in which a …


Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar Jan 2011

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

USF Tampa Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil …


The Portia Project: The Heiress Of Belmont On Stage And Screen, Ann Mccauley Basso Jan 2011

The Portia Project: The Heiress Of Belmont On Stage And Screen, Ann Mccauley Basso

USF Tampa Graduate Theses and Dissertations

Until now, there has not been a performance history of The Merchant of Venice that focuses on Portia, the main character of the play. Although she has the most lines, the most stage time, and represents the nexus of the action, Portia has often been hidden in Shylock's shadow, and this dissertation seeks to bring her into the spotlight. The Portia Project is a contribution to literary and theatrical history; its primary goal is to provide a tool for scholars and teachers. Moreover, because of Merchant's notoriously problematic nature, the play invites different perspectives. By presenting the diverse ways that …


Drug Courts Work, But How? Preliminary Development Of A Measure To Assess Drug Court Structure And Processes, Blake Barrett Jan 2011

Drug Courts Work, But How? Preliminary Development Of A Measure To Assess Drug Court Structure And Processes, Blake Barrett

USF Tampa Graduate Theses and Dissertations

The high prevalence of substance use disorders is well-documented among criminal offenders. Drug courts are specialty judicial programs designed to: 1) improve public safety outcomes; 2) reduce criminal recidivism and substance abuse among offenders with substance use disorders; and 3) better utilize scarce criminal justice and treatment resources. Drug courts operate through partnerships between the criminal justice, behavioral health and public health systems. Offenders participate in an intensive regimen of substance abuse treatment and case management while under close judicial supervision. Drug courts' effectiveness in reducing criminal recidivism and drug use has been documented through numerous primary studies as well …


The Role Of Discrete Emotions In Predicting Counterproductive Work Behavior, Jeremy Allen Bauer Jan 2011

The Role Of Discrete Emotions In Predicting Counterproductive Work Behavior, Jeremy Allen Bauer

USF Tampa Graduate Theses and Dissertations

The current study investigates how discrete negative emotions are related to specific facets of counterproductive work behaviors (CWB). The sample consisted of 241 employees who reported their frequency of experiencing negative emotions and their frequency of committing CWBs in the workplace. For 103 employees, supervisor reports of employee CWB were also obtained. The findings provide evidence that a wide range of negative emotions are related to most of the sub facets of CWB. There was also some evidence that supervisor reports differ systematically from employee reports of CWB. The theoretical, methodological, and organizational implications are discussed.


_Alien_ Thoughts: Spectatorial Pleasure And Mind Reading In Ridley Scott's Horror Film, Cecilia Madeline Bolich Jan 2011

_Alien_ Thoughts: Spectatorial Pleasure And Mind Reading In Ridley Scott's Horror Film, Cecilia Madeline Bolich

USF Tampa Graduate Theses and Dissertations

Pleasure experienced in an unpleasant film genre, like horror, has prompted numerous discussions in film studies. Noted scholars like Carol J. Clover and Noël Carroll have rationalized spectatorial enjoyment of a genre that capitalizes on human anxieties and complicates cultural categories. Clover admits that horror initially satisfies sadistic tendencies in young male viewers but then pushes them to cross gender lines and identify with the strong female heroine who defeats the film's threat. Carroll provides a basic explanation, citing spectators' cognitive curiosity as the source of pleasure. Both scholars are right to consider emotional, psychological, and cognitive experiences felt by …

Principals' Content Knowledge: Examining The Relationship Between Principals' Reading Knowledge And Leadership Actions From Principals' And Teachers' Perceptions, Angela Suzanne Butler Jan 2011

Principals' Content Knowledge: Examining The Relationship Between Principals' Reading Knowledge And Leadership Actions From Principals' And Teachers' Perceptions, Angela Suzanne Butler

USF Tampa Graduate Theses and Dissertations

Principals' leadership content knowledge in reading was investigated by examining the relationship between the perceived reading knowledge of principals and perceived leadership actions principals take to support reading instruction. Survey results from 78 principals and 1,876 teachers were analyzed. Results showed a positive, statistically significant correlation between principals' perceptions of their reading knowledge and principals' perceptions of the actions they take to support reading. A stronger positive, significant correlation between teachers' perceptions of their principal's reading knowledge and teachers' perceptions of their principal's actions was also demonstrated. These correlations substantiated studies that purported principals with more reading knowledge are more …


A Modeling Analysis Of Dissolved Carbon Dioxide Discharged From Howard F. Curren Advanced Wastewater Treatment Plant, Dustin Capps Jan 2011

A Modeling Analysis Of Dissolved Carbon Dioxide Discharged From Howard F. Curren Advanced Wastewater Treatment Plant, Dustin Capps

USF Tampa Graduate Theses and Dissertations

Currently, the US Environmental Protection Agency primarily regulates the discharge of dissolved nitrogen and phosphorous from wastewater treatment plants in the United States. A recent study has shown that the treated effluent of many plants contains concentrations of dissolved carbon dioxide well above the expected theoretical equilibrium concentration of 0.6 mg/L, indicating that carbon dioxide may have been overlooked as a possible pollutant in receiving waters. For this reason, it is necessary to examine the possible presence of a discharge plume containing high levels of dissolved CO2 downstream from the outfall of a major wastewater treatment plant in Tampa, Florida. …

Sexually Explicit, Socially Empowered: Sexual Liberation And Feminist Discourse In 1960s Playboy And Cosmopolitan, Lina Salete Chaves Jan 2011

Sexually Explicit, Socially Empowered: Sexual Liberation And Feminist Discourse In 1960s Playboy And Cosmopolitan, Lina Salete Chaves

USF Tampa Graduate Theses and Dissertations

In this thesis, I provide an analysis of 1960s American popular culture by examining Playboy, "The Playboy Philosophy," Cosmopolitan, and Sex and the Single Girl. These cultural artifacts furthered the feminist movement by challenging gender structures and sexuality. I discuss how these publications focused on the advancement of the individual through careerism, consumerism and sexuality. These publications assisted in challenging and breaking down various aspects of gender and sexual boundaries and assisted in reworking social limitations that kept women from advancing themselves outside of the pre-set gender roles of domesticity. Regardless of the traditional feminist critique of …


Geochemical Systematics Among Amphibolitic Rocks In The Central Blue Ridge Province Of Southwestern North Carolina, Nathan Collins Jan 2011

Geochemical Systematics Among Amphibolitic Rocks In The Central Blue Ridge Province Of Southwestern North Carolina, Nathan Collins

USF Tampa Graduate Theses and Dissertations

The Central Blue Ridge sub-province of the southern Appalachian Mountains preserves an unique and complex geologic history. The Cartoogechaye terrane is the westernmost terrane of the Central Blue Ridge sub-province, and is characterized by extensive olistostromal sequences, including mafic-ultramafic massifs, isolated mafic units, and block-in-matrix structures of varying scales. This study investigates the genetic and tectonic relationships, and regional chemical and metamorphic trends of the amphibolitic rocks entrained within units of the Cartoogechaye and nearby terranes, toward constraining the origins of these regional sequences, and examining the rationale for the current Blue Ridge terrane designations.

A distinct compositional variation exists …


Inhibition Of P53 Dna Binding Function By The Mdm2 Acidic Domain, Brittany Lynne Cross Jan 2011

Inhibition Of P53 Dna Binding Function By The Mdm2 Acidic Domain, Brittany Lynne Cross

USF Tampa Graduate Theses and Dissertations

MDM2 regulates p53 predominantly by promoting p53 ubiquitination. However, ubiquitination-independent mechanisms of MDM2 have also been implicated. Here we show that MDM2 inhibits p53 DNA binding activity in vitro and in vivo. MDM2 binding promotes p53 to adopt a mutant-like conformation, losing reactivity to antibody Pab1620, while exposing the Pab240 epitope. The acidic domain of MDM2 is required to induce p53 conformational change and inhibit p53 DNA binding. ARF binding to the MDM2 acidic domain restores p53 wild type conformation and rescues DNA binding activity. Furthermore, histone methyl transferase SUV39H1 binding to the MDM2 acidic domain also restores p53 wild …


Modeling Roadside Safety Hazards To Predict Annual Crash Cost To Encroaching Vehicles In Rural Road Networks, Isidro Delgado Jan 2011

Modeling Roadside Safety Hazards To Predict Annual Crash Cost To Encroaching Vehicles In Rural Road Networks, Isidro Delgado

USF Tampa Graduate Theses and Dissertations

Roadside crashes account for a large portion of total fatal crashes that occur annually in the United States. About 30% of those fatalities are the result of single vehicle run-off-road crashes. A large proportion of these fatal crashes occur in rural roads when vehicles depart from the travel lane and collide with trees or other roadside safety hazards. Many of these run-off-road accidents occur in local roads that carry traffic volumes between 1,000 and 20,000 vehicles per day. Many of these roads are part of the jurisdiction of county authorities faced with the dilemma of having too many "potentially dangerous" …


Development Of A Non-Invasive Electrode For Intradermal Electrically Mediated Dna Vaccination, Amy Lynn Donate Jan 2011

Development Of A Non-Invasive Electrode For Intradermal Electrically Mediated Dna Vaccination, Amy Lynn Donate

USF Tampa Graduate Theses and Dissertations

Current progress in the development of vaccines has decreased the incidence of fatal and non-fatal infections and increased longevity. However, new technologies need to be developed to combat an emerging generation of infectious diseases. DNA vaccination has been demonstrated to have great potential for use against a wide variety of diseases. Alone, this vaccine technology does not generate a significant immune response for vaccination, but combined with delivery by electroporation (EP), can enhance plasmid expression and immunity against the expressed antigen. Most EP systems, while effective, can be invasive and painful making them less desirable for use in vaccination. Our …


Apparent Total Evaporative Resistance Values From Human Trials Over A Range Of Metabolic And Heat Stress Levels, Matthew David Dooris Jan 2011

Apparent Total Evaporative Resistance Values From Human Trials Over A Range Of Metabolic And Heat Stress Levels, Matthew David Dooris

USF Tampa Graduate Theses and Dissertations

Failure to maintain thermal equilibrium can cause uncontrollable increases in body core temperature beyond critical upper limits. In selecting clothing, consideration must be given to the heat transfer properties of clothing that may restrict the cooling capacity of the human body under heat stress conditions, most importantly, apparent total evaporative resistance (Re,T,a). This study calculated and compared Re,T,a for five clothing ensembles under varying heat stress conditions, including three relative humidity (RH) levels and three stages of heat stress to determine if Re,T,a values varied or remained the same with …


The Tyranny Of Plot: Anzia Yezierska's Struggle To Free The Voices Of Her Community Through The Autobiographical Self, Kristie Kelly Dowling Jan 2011

The Tyranny Of Plot: Anzia Yezierska's Struggle To Free The Voices Of Her Community Through The Autobiographical Self, Kristie Kelly Dowling

USF Tampa Graduate Theses and Dissertations

This thesis explores the very different ways that both the novel and autobiography mediate individual and group identities by comparing Anzia Yezierska's novel Salome of the Tenements to her autobiography Red Ribbon on a White Horse. Yezierska's texts establish the inherent difference between the novel and autobiography in that her novels contribute to the dominant ideology by colluding with the capitalist narrative of individualism while her autobiography resists that very narrative. In calling forth the multiple voices of her community, her autobiography reveals, in a series of metatextual comments, the fictional nature of the self and autobiography. Comparing these …


Elections And Tensions And Constitutions! Oh, My! A Process-Oriented Analysis Of Bolivian Democratization From 1993 To 2009, Laurel Kristin Dwyer Jan 2011

Elections And Tensions And Constitutions! Oh, My! A Process-Oriented Analysis Of Bolivian Democratization From 1993 To 2009, Laurel Kristin Dwyer

USF Tampa Graduate Theses and Dissertations

Many Latin American countries which underwent democratic regime transformations within the last thirst years have seemingly stalled. Unable to meet the demands of their citizens, which grow increasingly restless and confrontational, they have become subjected to a series of economic and political crises. Contemporary democratic theorists are at a loss to explain why this region has failed to deepen over time. The purpose of this paper is threefold: it questions the analytic utility of contemporary liberal and representative models, it argues for the inclusion of an alternative process-oriented model provided by Charles Tilly (2007), and tests this model through a …

Evaluating The Use Of Task Clarification, Self-Monitoring And Performance Feedback, Jennifer Marie Rodriguez

USF Tampa Graduate Theses and Dissertations

The effects of self-monitoring, task clarification, and performance feedback on the performance of critical tasks by assembly group supervisors in a manufacturing company were examined. This intervention involved the training of a supervisor to use task clarification, self-monitoring, and performance feedback to improve the work performance of the participating group leaders. A multiple baseline across participants and tasks design was used to examine the effects of the intervention. Measures included: generalization of group leader performance to another work period, procedural fidelity for training the supervisor, intervention integrity of the supervisor's training of the group leaders, treatment acceptability, and social validity. …


Modularizing Crosscutting Concerns In Software, Nalin Saigal Jan 2011

Modularizing Crosscutting Concerns In Software, Nalin Saigal

USF Tampa Graduate Theses and Dissertations

Code modularization provides benefits throughout the software life cycle; however, the presence of crosscutting concerns (CCCs) in software hinders its complete modularization. Traditional modularization techniques work well under the assumption that code being modularized is functionally orthogonal to the rest of the code; as a result, software engineers try to separate code segments that are orthogonal in their functionality into distinct modules. However, in practice, software does not decompose neatly into modules with distinct, orthogonal functionality. In this thesis, we investigate the modularization of CCCs in software using two different techniques.

Firstly, we discuss IVCon, a GUI-based tool that provides …

Identification Of Patient Recovery Patterns After Cardiovascular Surgery Based On Laboratory Tests Results, Alcides Ricardo Santander Mercado

USF Tampa Graduate Theses and Dissertations

In this dissertation is proposed a methodology to identify patient's recovery patterns after cardiovascular surgery based on laboratory tests results. The main purpose is to enhance the understanding of the manifestations of postsurgical complications in patients who underwent cardiovascular surgery. The analysis of patients' recovery process is based on the relationship between plasma calcium, ionized calcium and platelet count over time.

Laboratory results from the James A. Haley Veterans' Hospital databases, related to patients admitted to the Surgical Intensive Care Unit (SICU) after cardiac surgery (coronary artery bypass, aortic value replacement and mitral valve replacement), are used. These databases contain …


The Effects Of Manipulating Conditioned Establishing Operations On The Acquisition Of Mands In Children With Autism Spectrum Disorders, Claudia Troconis Jan 2011

The Effects Of Manipulating Conditioned Establishing Operations On The Acquisition Of Mands In Children With Autism Spectrum Disorders, Claudia Troconis

USF Tampa Graduate Theses and Dissertations

In Verbal Behavior, Skinner (1957) suggested that each verbal operant has independent response functions, in which acquiring one does not automatically result in the other, unless transfer between the verbal operants is directly trained. Although several researchers have shown that mands and tacts are functionally independent, more recent research has demonstrated that mands may emerge following tact training. However, this research has not clarified the influence of establishing operations on the emergence of pure mands following tact training. Therefore, the present study investigated the effects of tact training on the acquisition of impure and pure mands in children with autism …


Atrial Fibrillation Signal Analysis, Raja Sarath Chandra Prasad Vaizurs Jan 2011

Atrial Fibrillation Signal Analysis, Raja Sarath Chandra Prasad Vaizurs

USF Tampa Graduate Theses and Dissertations

Atrial fibrillation (AF) is the most common type of cardiac arrhythmia encountered in clinical practice and is associated with an increased mortality and morbidity. Identification of the sources of AF has been a goal of researchers for over 20 years. Current treatment procedures such as Cardio version, Radio Frequency Ablation, and multiple drugs have reduced the incidence of AF. Nevertheless, the success rate of these treatments is only 35-40% of the AF patients as they have limited effect in maintaining the patient in normal sinus rhythm. The problem stems from the fact that there are no methods developed to analyze …


Robotic Hand Evaluation Based On Task Specific Kinematic Requirements, Carlos Rafael Neninger Jan 2011

Robotic Hand Evaluation Based On Task Specific Kinematic Requirements, Carlos Rafael Neninger

USF Tampa Graduate Theses and Dissertations

With the rise autonomous and robotic systems in field applications, the need for dexterous, highly adaptable end effectors has become a major research topic. Control mechanisms of robotics hands with a high number independent actuators is recognized as a complex, high dimensional problem, with exponentially complex algorithms. However, recent studies have shown that human hand motion possesses very high joint correlation which translates into a set of predefined postures, or synergies. The hand produces a motion using a complementing contribution of multiple joints, called synergies. The similarities place variables onto a common dimensional space, effectively reducing the number of independent …
