Helping Break The Cycle Of School Violence And Aggression: A Program Evaluation Of The Owning Up Curricula, Stephanie T. Mihalas

USF Tampa Graduate Theses and Dissertations

This study explored the effects of a gender-based violence prevention program called Owning Up on a group of middle school students in Tampa, Florida. The majority of participants were African-American at-risk youth who voluntarily participated in the intervention. This study is novel in that it is one of the first to empirically validate curricula that addresses an array of aggressive behaviors. A mixed methods design was used to gain insight into significant changes over time, as well as treatment integrity throughout the implementation. Findings from the study found females to be more aggressive than males on all forms of aggression …

A Heuristic Methodology For Locating Monitoring Stations To Detect Contamination Events In Potable Water Distribution Systems, James R. Chastain Jr.

USF Tampa Graduate Theses and Dissertations

The requirements to protect public water systems from intentional contamination have expanded in the years following September 11, 2001. The areal extent and non-linear nature of water demand and movement in the distribution system makes efficient location of sampling points difficult. This difficulty is compounded by the fact that contamination conceptually can occur at any point and at any time within the distribution system. Small to mid-sized water systems are especially at a disadvantage in addressing this issue due to limited resources available to them.

This paper proposes a heuristic methodology to identify strategic locations within the system that can …

A Multilevel Modeling Analysis Of The Geographic Variability Of Low Birth Weight Occurrence In Florida, Joseph William Green

USF Tampa Graduate Theses and Dissertations

The associations of neighborhood level socioeconomic deprivation and low birth weight were investigated among 1,030,443 singleton live births in the State of Florida between the years 1992 and 1997. Census data for per capita income, unemployment, percent of individuals living below the poverty line, vehicle ownership and educational attainment were used as neighborhood level indicators of socioeconomic status. Additionally, these variables were combined into a deprivation index to measure relative deprivation of neighborhoods across Florida. Birth data were linked to census block groups and tracts, which were used as proxies for low birth weight. Multilevel models were used to model …

The Generation Of A Digital Phantom For Testing Of Digitally Reconstructed Radiographs, Nicholas Andrew, Mason

USF Tampa Graduate Theses and Dissertations

The construction of phantoms for testing imaging parameters has been well documented in the literature. As computers have been introduced into the different areas of medicine, they have become more and more relied upon to replace conventional technologies. One specific example is that of plane film X-rays. Digitally Reconstructed Radiographs (DRR's) are computer generated images that are generated from a 3 D volume of data, such as CT or MRI axial scans, and can be used in place of conventional X rays. The computer can generate a DRR image for any position, orientation and magnification, and geometries not physically possible …

Relationship Advertising: Investigating The Strategic Appeal Of Intimacy (Disclosure) In Services Marketing, Andrea Diahann Gaye Scott

USF Tampa Graduate Theses and Dissertations

One approach to communicating and thereby building a close relationship with consumers is via advertising. In other words, if service providers can invoke feelings of connection and intimacy--where consumers feel understood, cared for, and validated--through advertising, a stronger bond and sense of loyalty is likely to follow. When intimacy is conceived as knowing and being known by another, which incorporates mutual and reciprocal (though not necessarily equal) liking and vulnerability, its application extends beyond romantic relationships to the current context of relationship and services marketing. This research provides empirical support for the use of intimacy as an appeal in services …

An Examination Of Peer-Related Risk And Protective Factors For Body Image Disturbance And Disordered Eating Among Adolescent Girls, Hemal M. Shroff

USF Tampa Graduate Theses and Dissertations

Research has documented the impact of peer influences on adolescents for health risk behaviors such as smoking and drinking alcohol. However, few studies have done an in-depth investigation of peer-related risk and protective factors affecting body dissatisfaction and disordered eating among adolescent girls. The study sample consisted of 344 adolescent girls from high schools in Pasco County, Florida. Participants completed questionnaires assessing the impact of peers on their weight and appearance attitudes, beliefs and behaviors. Participants also identified their close friends (using a coding system) and rated their own figures. Trained research assistants provided objective figure ratings for the participants. …

Utility Of Positive Peer Reporting To Improve Interactions Among Children In Foster Care, Jenny L. Van Horn

USF Tampa Graduate Theses and Dissertations

This study investigated the utility of positive peer reporting to improve placement outcomes in foster care settings. Rejected children are likely to exhibit disruptive behavior problems due to frequent negative interactions with their peers, augmenting an already unstable environment in foster care. Researchers have found positive peer reporting to be successful in increasing social status and positive interactions and reducing negative interactions. Utilizing a multiple baseline with reversal elements, this study examined the effects of positive peer reporting on the positive and negative interactions of socially rejected children in foster care settings. Results supported previous literature with the first participant's …

Effects Of Weight-Related Cues On Smoking Motivation, Elena Nicole Lopez

USF Tampa Graduate Theses and Dissertations

Smoking is now the leading cause of preventable death and disease in women. Understanding women's motivations to smoke is important in developing effective cessation and relapse prevention programs. Women, more so than men, appear to associate their smoking behavior to issues of weight. Although a general relationship between weight concerns and smoking has been found among women, a causal relationship had not been demonstrated. This study tested whether activation of negative body image cognitions would produce greater urges to smoke and whether the relationship would be moderated by trait body dissatisfaction and mediated by state body dissatisfaction.

A randomized 2 …

Moonlight In Miami: A Field Study Of Human-Robot Interaction In The Context Of An Urban Search And Rescue Disaster Response Training Exercise, Jennifer L. Burke

USF Tampa Graduate Theses and Dissertations

This study explores human-robot interaction during a 16-hour high-fidelity Urban Search and Rescue (USAR) disaster response drill with teleoperated robots. Situation awareness and team interaction were examined using communication analysis. Operators (n=5) sought assistance from team members to compensate for difficulties building or maintaining situation awareness. Operator-team member communication focused on relating what was seen through the robot's eye view with prior knowledge and planning search strategies. Results suggest operators need a new cognitive mental model to filter and comprehend data provided by the robot, and that robot-assisted search is a team task rather than an individual one. USAR technical …

Graphical Probabilistic Switching Model: Inference And Characterization For Power Dissipation In Vlsi Circuits, Shiva Shankar Ramani

USF Tampa Graduate Theses and Dissertations

Power dissipation in a VLSI circuit poses a serious challenge in present and future VLSI design. A switching model for the data dependent behavior of the transistors is essential to model dynamic, load-dependent active power and also leakage power in active mode - the two components of power in a VLSI circuit. A probabilistic Bayesian Network based switching model can explicitly model all spatio-temporal dependency relationships in a combinational circuit, resulting in zero-error estimates. However, the space-time requirements of exact estimation schemes, based on this model, increase with circuit complexity [5, 24]. This work explores a non-simulative, importance sampling based, …

Optimal Design Of An Accelerated Degradation Experiment With Reciprocal Weibull Degradation Rate, Indira Polavarapu

USF Tampa Graduate Theses and Dissertations

To meet increasing competition, get products to market in the shortest possible time, and satisfy heightened customer expectations, products must be made more robust and fewer failures must be observed in a short development period. In this circumstance, assessing product reliability based on degradation data at high stress levels becomes necessary. This assessment is accomplished through accelerated degradation tests (ADT). These tests involve over stress testing in which instead of life product performance is measured as it degrades over time. Due to the role these tests play in determining proper reliability estimates for the product, it is necessary to scientifically …

Affective Dispositions And Cognitive Skills In Critical Thinking: Implications For Measurement, Training, And Team Performance, Timothy John Willis

USF Tampa Graduate Theses and Dissertations

This study attempts to increase critical thinking among teams by making them cognizant of seven critical thinking dimensions. Forty three-person teams of undergraduates worked together on a complex decision-making task. Each team received training in and was asked to ensure their group exhibited the characteristics of cognitive skills, affective dispositions, both of these or neither. Critical thinking was assessed using self-report, behavioral observation rating, and expert outcome analysis. The findings suggest training in affective dispositions increases the exhibition of at least one dimensions of critical thinking. A behavioral measurement is presented and evaluated with respect to established critical thinking methods.

Peripheral Nerve Repair Using Biomaterial Nerve Guides Containing Guidance Channels, Oren D. Rosenthal

USF Tampa Graduate Theses and Dissertations

Traumatic injuries to peripheral nerves often leave gaps that cannot be repaired by direct suture methods. In such instances, repair with a tubular nerve guide, allows connection of the nerve ends, provides directional guidance, and concentrates endogenous trophic factors for regenerating axons. We hypothesized that collagen nerve guides containing longitudinally oriented channels would further improve the outcome of nerve repair by increasing the surface area available for cell migration. We restored the continuity of a 10mm peripheral nerve gap (rat sciatic nerve) by suturing the nerve stumps into a type I collagen nerve guide (1.5 mm ID), which contained longitudinal …

Multi-Robot Task Allocation Using Affect, Aaron Gage

USF Tampa Graduate Theses and Dissertations

Mobile robots are being used for an increasing array of tasks, from military reconnaissance to planetary exploration to urban search and rescue. As robots are deployed in increasingly complex domains, teams are called upon to perform tasks that exceed the capabilities of any particular robot. Thus, it becomes necessary for robots to cooperate, such that one robot can recruit another to jointly perform a task. Though techniques exist to allocate robots to tasks, either the communication overhead that these techniques require prevents them from scaling up to large teams, or assumptions are made that limit them to simple domains. This …

Technology And Teacher Training: The Systematic Design And Development Of A Framework For Integrating Technology Into Jamaica’S Teacher Training Programs, Carol N. Granston

USF Tampa Graduate Theses and Dissertations

Over the last five years, there has been an increased number of computers in schools and teachers' colleges in Jamaica. In addition, recently revised national policy documents have indicated the need to infuse technology into the curricula of all schools. Despite these investments in computers, however, there has been little corresponding development in training teachers to use computers and emerging technologies as teaching learning tools.

The purposes of the study were three-fold: (a) to describe the current state of technology integration in Jamaica's teacher training programs (b) assess the extent to which teachers' college faculty and pre-service teachers perceived themselves …

Intelligent Telerobotic Assistance For Enhancing Manipulation Capabilities Of Persons With Disabilities, Wentao Yu

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the development of a telemanipulation system using intelligent mapping from a haptic user interface to a remote manipulator to assist in maximizing the manipulation capabilities of persons with disabilities. This mapping, referred to as assistance function, is determined on the basis of environmental model or real-time sensory data to guide the motion of a telerobotic manipulator while performing a given task. Human input is enhanced rather than superseded by the computer. This is particularly useful when the user has restricted range of movements due to certain disabilities such as muscular dystrophy, a stroke, or any form of …

Design And Evaluation Of The Combined Input And Crossbar Queued (Cicq) Switch, Kenji Yoshigoe

USF Tampa Graduate Theses and Dissertations

Packet switches are used in the Internet to forward information between a sender and receiver and are the critical bottleneck in the Internet. Without faster packet switch designs, the Internet cannot continue to scale-up to higher data rates. Packet switches must be able to achieve high throughput and low delay. In addition, they must be stable for all traffic loads, must efficiently support variable length packets, and must be scalable to higher link data rates and greater numbers of ports. This dissertation investigates a new combined input and crossbar queued (CICQ) switch architecture.

Some unbalanced traffic loads result in instability …

Evaluation Of Digital Imaging Systems Used In Highway Applications, Alex Mraz

USF Tampa Graduate Theses and Dissertations

Manual pavement condition surveys are gradually replaced by more comprehensive automated surveys conducted by multi-function highway evaluation vehicles. Highway evaluation vehicles are generally equipped with laser profiling, land navigation, and imaging sub-systems. The imaging system consists of three cameras; forward-view and side-view digital area-scan cameras for capturing images of traffic signs and right-of-way safety features, and a pavement digital line-scan or area-scan camera for capturing images of the pavement surface. In addition to the 3-laser and accelerometer-based profiling system, these vehicles are also equipped with differential global positioning equipment (DGPS) and an inertial measurement unit (IMU) for cross-slope, curvature and …

Cord Blood Cell Therapy For Ischemic Stroke, Martina Vendrame

USF Tampa Graduate Theses and Dissertations

Infusion of the "mononuclear fraction" of human cord blood cells (HUCBC), which is composed of immature blood cells and hematopoietic progenitors, is known to reduce neurobehavioral deficits in rats subject to middle cerebral artery occlusion (MCAO). When MCAO rats are infused with 106 cells 24 hours after the induction of the stroke, their motor function improves. To extend these findings, we first examined the behavioral recovery of MCAO rats in the presence of increasing doses of HUCBC. The recovery in behavioral performance seen with measurements of spontaneous activity and motor deficits, depended on the amount of cells delivered, with 10 …

Behavioral And Morphological Consequences Of Rearing Florida Largemouth Bass With Non-Elusive Prey, Alpa Patel Wintzer

USF Tampa Graduate Theses and Dissertations

(1) Hatchery-reared Florida largemouth bass, Micropterus salmoides floridanus, feed on inert pellet food while their wild counterparts capture elusive prey. Differences in levels of prey elusivity often mandate the use of alternate methods of prey capture and are accompanied by a related phenotypic change.

(2) This study investigates (a) differences between the prey capture kinematics and strike modes of hatchery and wild juvenile Florida largemouth bass raised on pellets and live prey, and (b) whether elusivity-based variation in prey capture translates to a phenotypic and functional change during skull development.

(3) Analysis of high-speed videography demonstrates that wild bass capture …

An Application Of The Grundgestalt Concept To The First And Second Sonatas For Clarinet And Piano, Op. 120, No. 1 & No. 2, By Johannes Brahms, Devon Burts

USF Tampa Graduate Theses and Dissertations

A distinct feature of Brahms's compositional style is the cumulative development of melodic material that occurs throughout the composition. This motivic treatment appears in rhythmic and pitch fragments that are prolonged though various repetitions and newly derived figures related to earlier statements at the beginning of the composition. The compositional practices of Brahms as they relate to thematic unity reflect an earlier concept of the Grundgestalt, described in elements of nature by the 19th century philosopher, Johann Wolfgang von Goethe. The creative application of this concept by Brahms influenced the work of Arnold Schoenberg, who provided a more formal …

Radical Religious Groups And Government Policy: A Critical Evaluation, Tori Chambers Lockler

USF Tampa Graduate Theses and Dissertations

Religion, many times, is one of the phenomena that is misunderstood and often rejected due to apprehension. There is an expected "norm" within our culture for religion and those that fall outside that "norm" are typically criticized for their beliefs. Within Christianity there are a number of extremist groups that follow millennial doctrines and believe they are living in the end times. These organizations tend to view the government as oppressive, disrespectful, immoral and corrupt. Because of this when an incident occurs with one of these millennial groups and the government steps in to control the situation, the way it …

Multiple Hazards And Community Vulnerability In Hillsborough County, Florida, Keith Allen Albury

USF Tampa Graduate Theses and Dissertations

Hillsborough County, Florida is subject to a variety of natural and technological hazards, which have the potential to threaten both the population and the built environment. This research focuses on several natural hazards (coastal flooding, sink hole, and hurricane) and technological hazards (toxic transportation spills and toxic release from fixed storage facilities) and the population that is potentially exposed to these hazards. Social vulnerability for this population was determined using racial composition, gender, age and household rental/ownership status.

Both social vulnerability and exposure to hazardous conditions occur as a continuum across geographical space. The determination of who is exposed; the …

Physiological Responses Of Men During The Continuous Use Of A Portable Liquid Cooling Vest, Theresa J. Medina

USF Tampa Graduate Theses and Dissertations

Heat stress is a well documented hazard across industries. The combination of environmental conditions, work demands, and clothing contribute to heat strain. Left unchecked, heat strain causes changes in an individual's physiological state that can lead to serious and fatal conditions with little warning. Although engineering and administrative controls are the first choice to abate this hazard, they frequently are not feasible. In these cases, personal cooling is often employed. There are three main types of personal cooling: liquid, air, and passive. Each has its own advantages and disadvantages.

This study focuses on continuous cooling using a portable liquid cooling …

Governing Wayward Consumers: Self-Change And Recovery In Debtors Anonymous, Adam Morenberg

USF Tampa Graduate Theses and Dissertations

Previous research on self-change in support groups has focused on the ways individuals accomplish self-change in the "local cultures" of the support group settings. This ethnographic study of the 12-step self-help group Debtors Anonymous (DA) departs from that tradition by focusing on the ways that DA members achieve self-change by employing "recovery" strategies learned from the group in their everyday lives. DA members enter the group during financial crises, and often believe they cannot manage their own personal finances. By learning techniques of financial management taught by the group, DA members gradually gain "sobriety" and financial management skills. This analysis …

Women, Domestic Abuse, And Dreams: Analyzing Dreams To Uncover Hidden Traumas And Unacknowledged Strengths, Mindy Stokes

USF Tampa Graduate Theses and Dissertations

Domestic abuse is the number one cause of injury to women in the United States. Women and their children flee everyday to shelters to escape the abuse. Once inside the shelters, material resources are rendered so that the women can continue to lead lives outside the shelter and different therapies are employed so that the women can better understand the abuse and their options once leaving. A type of therapy used in other therapeutic forums, such as patients sexually abused as children, is dream analysis. This type of therapy has allowed formerly traumatized victims a safe space to uncover hidden …

The Importance Of Program-Delivered Differential Reinforcement In The Development Of Classical Music Auditory Discrimination, Gudmundur Torfi Heimisson

USF Tampa Graduate Theses and Dissertations

Posttest performances after two forms of Web-based tutorial instruction were compared. Both forms were designed to teach students to identify musical compositions that typify Renaissance, Baroque, Classical, Romantic, and 20th Century music. The first treatment condition was a series of Web pages with text and accompanying hyperlinks to musical selections matched to the text. In this condition, students read and listened at their own discretion -- without Web software program restrictions. The second treatment contained exactly the same text and musical selections, but students in this condition read the text in small portions while being required to fill in missing …

An Empirical Analysis Of The Role Of Mitigation In Capital Sentencing In North Carolina Before And After Mckoy V. North Carolina (1990), Janine Kremling

USF Tampa Graduate Theses and Dissertations

This study focuses on the influence of mitigating circumstances on the sentencing outcome before and after the McKoy (1990) decision. In McKoy (1990) the Supreme Court decided that the jurors did not have to find mitigating circumstances unanimously. Results are reported based on a sample of North Carolina first-degree murder cases where the state sought the death penalty. Logistic regression is used to determine the importance of mitigating circumstances as predictors of jury decision-making in North Carolina, controlling for the variety of other factors that influence that decision.

The descriptive statistics show that the average number of mitigating circumstances submitted …

“Symbolism Of Language: A Study In The Dialogue Of Power Between The Imperial Cult And The Synoptic Gospels”, Sharon Matlock-Marsh

USF Tampa Graduate Theses and Dissertations

Long before the writings of the New Testament gospels, where Jesus was being proclaimed as the Son of God, and Savior, the world existing under the influences of Hellenism resulting from the conquests by Alexander the Great in 323 BCE, had already been well acquaint

ed with and expected to hear certain symbolic language in determining titles for their divine ruler the emperor. Living within a cosmological framework, i.e., a sacred cosmos, the citizens of the empire accepted the emperor as the manifestation of divinity in the world. This belief existed for centuries prior to Christianity as a reality that …

Chemical And Biological Investigation Of The Antarctic Red Alga Delisea Pulchra, Santhisree Nandiraju

USF Tampa Graduate Theses and Dissertations

Our interest in the red alga Delisea pulchra (=D.fimbriata) (Greville) Montagne 1844 (Rhodophyceae, Bonnemaisoniales, Bonnemaisoniaceace) was stimulated by its activity in the biosssays done at Wyeth Pharmaceuticals. Halogenated compounds from D. pulchra interfere with Gram-negative bacterial signaling systems, affect the growth of Gram-positive bacteria, inhibit quorum sensing and swarming motility of marine bacteria (inhibit bacterial communication). They also inhibit surface colonization in marine bacteria and exhibit antifouling properties against barnacle larvae and macroalgal gametes.

Chemical investigation of D.pulchra collected near Palmer Station, Antarctica yielded three new dimeric halogenated furanones, pulchralide A-C (41-43), along with previously reported …
