Human Trafficking From Southern Mexico, Honduras, El Salvador, And Guatemala: Why These Victims Are Trafficked Into Modern Day Florida, Timothy Adam Golob

USF Tampa Graduate Theses and Dissertations

Florida is ranked as one of the United States' top three destination states for human trafficking; many of those victims originate from Mesoamerica--Southern Mexico, Guatemala, Honduras, and El Salvador. Human trafficking is a growing problem which hinders universal human rights for hundreds of new victims in Florida every year. Mesoamericans have a high risk of becoming victims due to the situations in their home countries. The issue of human trafficking has only recently gained the national and state attention of law makers and law enforcement officers.

This study uses several human trafficking cases to educate and exemplify why Mesoamerican victims …

Water Availability As The Driving Factor Of Growth And Physiological Function Of Co-Occurring Scrub Species In Central Florida, Tammy Foster

USF Tampa Graduate Theses and Dissertations

Florida scrub is a xeromorphic upland shrub community dominated by evergreen oaks that resprout after fire, occurring on moderately to excessively well-drained nutrient-poor sand. Scrub is home to several threatened and endangered animal species (e.g., Florida scrub-jay, gopher tortoise, and indigo snake) and rare and endemic plants. Urban development and agriculture has greatly reduced and fragmented scrub habitat, and because of this Florida scrub is considered one of the most endangered ecosystems in the United States. Climate change is a further threat to Florida scrub. Under a warmer and drier climate, scrub species will be exposed to more frequent and …

Statistical And Prognostic Modeling Of Clinical Outcomes With Complex Physiologic Data, Monica A. Puertas

USF Tampa Graduate Theses and Dissertations

Laboratory tests are a primary resource for diagnosing patient diseases. However, physicians often make decisions based on a single laboratory result and have a limited perspective of the role of commonly-measured parameters in enhancing the diagnostic process. By providing a dynamic patient profile, the diagnosis could be more accurate and timely, allowing physicians to anticipate changes in the recovery trajectory and intervene more effectively.

The assessment and monitoring of the circulatory system is essential for patients in intensive care units (ICU). One component of this system is the platelet count, which is used in assessing blood clotting. However, platelet counts …

Transcriptional Control Of Toxoplasma Development, Joshua Byran Radke

USF Tampa Graduate Theses and Dissertations

Toxoplasma gondii is an obligate intracellular protozoan parasite of animals and man. The asexual life cycle of Toxoplasma involves three very distinct, but tightly coordinated developmental stages. In nature, the sporozoite (contained within an oocyst) and bradyzoite (contained within a tissue cyst) initiate infection of the intermediate host, followed by rapid differentiation into the actively replicating tachyzoite. When countered by an effective host response, the tachyzoite differentiates back into the latent bradyzoite and this unique ability of Toxoplasma to interconvert between the replicating tachyzoite and the latent bradyzoite within a single host is the cause of life long infection. The …

Baseline Studies Of Selected Polybrominated Diphenyl Ethers In The Air Of The Nandamojo Watershed, Costa Rica, Mary Sophia Geesey

USF Tampa Graduate Theses and Dissertations

Polybrominated diphenyl ethers (PBDEs) have been used as flame retardants in a number of common household and commercial products around the world. PBDEs enter the environment in a variety of ways, such as through emissions, leaching from end-of-life electronics in landfills, and incineration. While many countries have phased out the manufacturing of penta-, octa-, and deca-PBDEs or have banned the manufacture and use of these congeners altogether, these persistent organic pollutants (POPs) continue to be detected in humans and the environment.

This study investigates spatial and temporal variations of selected PBDEs in the air of the Nandamojo watershed area in …

Promoting Generalization Of Skills Acquired Through Behavioral Skills Training With Embedded Visual Prompts, Andrea N. Perdomo

USF Tampa Graduate Theses and Dissertations

Studies on the "Tools" for Positive Behavior Change were originally conducted with people involved in the foster care system. Few studies have conducted the trainings in classroom environments to increase the positive interactions between teachers and their students. Numerous studies have demonstrated the usefulness of behavioral skills training in teaching a wide variety of behavioral skills; however, relatively few of them have shown generalization to their natural environment and maintenance of appropriate responding following the training. Methods of prompting following the initial trainings that have been utilized are often quite intrusive especially when it interrupts the flow of the participants' …

An Evaluation Of Group Contingency Interventions: The Role Of Teacher Preference, Christina Ennis

USF Tampa Graduate Theses and Dissertations

Disruptive behavior within classrooms is a major concern for teachers and parents. Positive Behavior Interventions and Supports (PBIS) provides a multi-tiered framework for schools to provide supports to students, which are matched to each student's needs. Whereas most students are successful with the school-wide supports provided to all students, approximately 20% of students are likely to require additional supports. Group contingencies have an established basis of support as effective Tier 2 interventions; however, these contingencies vary in a variety of dimensions that may influence their efficacy and acceptability. The purpose of this study was to evaluate the relative impact of …

Comparing Two Perspectives For Understanding Decisions From Description And Experience, Sandra S. Kauffman

USF Tampa Graduate Theses and Dissertations

When trying to make sense of uncertain situations, we might rely on summary information from a description, or information gathered from our personal experience. There are two approaches that both attempt to explain how we make risky decisions using descriptive or experiential information—the cognitive-based explanation from the description-experience gap, and the emotion-based explanation from the somatic marker hypothesis (SMH). This dissertation brings together these two approaches to better understand how we make risky decisions.

Four options were presented, with options differing in terms of advantageousness and riskiness. How easy or difficult it was to consciously comprehend the reward structure, or …

Accuracy Of Educators In Identifying Middle School Students With Elevated Levels Of Anxiety Or Depression, Cheryl Gelley

USF Tampa Graduate Theses and Dissertations

Schools need accurate and efficient ways to identify youth with mental health problems, in part to provide services to such students whose mental health concerns pose barriers to learning. The present study involved an investigation of the accuracy of one method--relying on educators (teachers, a team of school-based mental health professionals, and a school nurse) to identify early adolescents who self-report elevated levels of anxiety or depression. With respect to teachers as screening agents, the possible variability in rates of accurate identification as a function of number of teachers involved in the process (i.e., pooling nominations from multiple subject area …

Aeschynē In Aristotle's Conception Of Human Nature, Melissa Marie Coakley

USF Tampa Graduate Theses and Dissertations

This dissertation provides a thorough examination of the role of aeschynē (as distinct from aidōs) in Aristotle’s conception of human nature by illuminating the political and ethical implications of shame and shamelessness and the effect of these implications in his treatises. It is crucial, both to one’s own personhood and eudaimonia as well as to the existence of a just and balanced state, that aeschynē be understood and respected because of the self-evaluating ability that it maintains.

The aim of this work is to show that a recognition and appreciation of aeschynē as understood in Aristotle’s conception of human …

Exploration Of Mutations In Erythroid 5-Aminolevulinate Synthase That Lead To Increased Porphyrin Synthesis, Erica Jean Fratz

USF Tampa Graduate Theses and Dissertations

5-Aminolevulinate synthase (ALAS; EC 2.3.1.37) is a pyridoxal 5'-phosphate (PLP)-dependent enzyme that catalyzes the first committed step of heme biosynthesis in animals, the condensation of glycine and succinyl-CoA yielding 5-aminolevuliante (ALA), CoA, and CO2. Murine erythroid-specific ALAS (mALAS2) variants that cause high levels of PPIX accumulation provide a new means of targeted, and potentially enhanced, photosensitization. Transfection of HeLa cells with expression plasmids for mALAS2 variants, specifically for those with mutated mitochondrial presequences and a mutation in the active site loop, caused significant cellular accumulation of PPIX, particularly in the membrane. Light treatment of HeLa cells expressing mALAS2 variants revealed …

Acquisition Of A Social Problem Solving Method By Caregivers In The Foster Care System: Evaluation And Implications, Evan Ann Skelton

USF Tampa Graduate Theses and Dissertations

All youth are faced with many social issues and problems on a daily basis, and youth in foster care are often less equipped than their peers to make good decisions for themselves. The SODAS problem solving method is a component of the Transition to Independence Process (TIP) model and is intended for personnel to use with youth to help them make better decisions when faced with difficult situations. The SODAS method is designed to guide youth through a problem solving method for a current situation, and over time to acquire improved problem solving skills. Three caregivers at a group facility …

Communication Behavior Study Of Support In The Arts Using The Situational Theory Of Publics And The Theory Of Reasoned Action, Ashleigh Gallant

USF Tampa Graduate Theses and Dissertations

The Arts in the United States has been a thoroughly studied topic, largely trying to substantiate its value to society, resulting in a plethora of research that positively correlates the arts and a more healthy and successful society. Findings from various studies over the years have shown declines in arts support in the form of funding, advocacy, education, and participation (National Endowment for the Arts, 2009). Additional studies have suggested that millennials are redefining what participation means in the arts, and even the definition of the arts. The primary research question of this study is why are support for the …

The United States Prison System: A Comparative Analysis, Rachel O'Connor

USF Tampa Graduate Theses and Dissertations

Throughout history the penal system has been viewed as the paramount means of dealing with criminals, though its function has transformed throughout time. It has served as a pit for detaining suspected criminals, a home for the vagrant, an institution for the insane, a dreaded place of repute, quarters for cleansing and renewal, and an establishment of cataloged charges. The trials and transformations of history have developed and shaped the institution that we recognize today. Presently, the United States prison population far exceeds that of any other country in the world. The political climate, tough on crime policies, determinate sentencing, …

Reconceptualizing The Role Of Essentialism In Attitudes Toward Gays And Lesbians: The Intersection Of Gender And Sexual Orientation, Vanessa Hettinger

USF Tampa Graduate Theses and Dissertations

Social psychology researchers have become increasingly interested in the role of essentialist beliefs in predicting attitudes toward social groups. However, there is little agreement about what the term actually means, whether it means different things for different groups, what endorsement of essentialism (or its sub-components) means for attitudes, and how much this varies depending on the relevant social context. This underlying lack of clarity helps to explain some of the difficulty in understanding the relationships between essentialist beliefs about sexual orientation and attitudes toward gay men and lesbians. In the current project, I suggest a fundamental shift in the approach …

Motherhood Bound By State Supervision: An Exploratory Study Of The Experiences Of Mothers On Parole And Probation, Kaitlyn Robison

USF Tampa Graduate Theses and Dissertations

With an influx of women entering the incarcerated population comes an increase in the number of children who have a mother serving time. As these mothers are released from prison or jail they immediately enter into the parole or probation system. This research focuses on the experiences of these women within state supervision, but also on what it means to be a mother. Through thematic analysis of 8 in-depth interviews with women who are currently on or were recently released from probation or parole, this study explores how women manage the combined identity of "mother under state supervision."

Agriculture, Environmental Restoration And Ecosystem Services: Assessing The Costs Of Water Storage On Agricultural Lands In South Florida, Kayla Ouellette

USF Tampa Graduate Theses and Dissertations

A large part of the environmental restoration required by the Comprehensive Everglades Restoration Plan calls for more water-storage on lands south of Lake Okeechobee in order to restore the natural water flows of the Everglades watershed. The Everglades Agricultural Area (EAA) can be used for increased water storage in order to relieve coastal estuaries of excess water in the rainy season. This water storage can deliver additional ecosystem services of soil retention and reduced CO2 emissions that could compensate farmers for the cost of water storage by increasing long term farm profitability. The goals of this study were 1) to …

Testing The Feasibility Of Bioacoustic Localization In Urban Environments, Blaire O'Neal

USF Tampa Graduate Theses and Dissertations

Bioacoustics is a relatively new field of research focused on studying the acoustic signals of vocal animal species. The field has been a topic of interest for many years due its passive approach and avoidance of species-level limitations, such as tracking rare or nocturnal species. It has been used to locate birds in terrestrial environments; however, localization in urban environments remains unstudied. This research aims to fill the gap by attempting to estimate the location of 30 discrete calls in eight unique, urban environments. Sites represented two distinct traffic scenarios: moderate traffic and high traffic. Three system arrays of three …

"Die Mauer Im Kopf": Aesthetic Resistance Against West-German Take-Over, Arwen Puteri

USF Tampa Graduate Theses and Dissertations

Even 24 years after the Fall of the Berlin Wall, modern day Germans are still preoccupied with the contentious dynamics of the post-Wall unification process. Concern with geo-political fractiousness is deeply rooted in German history and the reason for Germany's desire to become a unified nation. The Fall of the Wall, and the subsequent rejection of socialism, was a chance to recover and unify what was perceived to be an "incomplete" nation. Yet, despite these actions, social unity between East and West Germans has never occurred and the Wall still persists as a metaphorical barrier in the minds of German …

[M3(Μ3-O)(O2cr)6] And Related Trigonal Prisms: Versatile Molecular Building Blocks For 2-Step Crystal Engineering Of Functional Metal-Organic Materials, Alexander Schoedel

USF Tampa Graduate Theses and Dissertations

Metal-organic materials (MOMs) assembled from metal-based building blocks and organic linkers have attracted much interest due to their large pore dimensions and their enormous structural diversity. In comparison to their inorganic counterparts (zeolites), these crystalline materials can be easily modified to tailor pore dimensions and functionality for specifically targeted properties.

The work presented herein encompasses the development of a synthetic 2-step process for the construction of novel families of MOMs or 'platforms' and allow us exquisite design and control over the resulting network topologies. Examples of cationic mesoporous structures were initially exploited, containing carboxylate based centers connected by metal-pyridine bonds. …

Multi Sensor System For Pedestrian Tracking And Activity Recognition In Indoor Environments, Juan Jose Marron Monteserin

USF Tampa Graduate Theses and Dissertations

The widespread use of mobile devices and the rise of Global Navigation Satellite Systems (GNSS) have allowed mobile tracking applications to become very popular and valuable in outdoor environments. However, tracking pedestrians in indoor environments with Global Positioning System (GPS)-based schemes is still very challenging given the lack of enough

signals to locate the user. Along with indoor tracking, the ability to recognize pedestrian behavior and activities can lead to considerable growth in location-based applications including

pervasive healthcare, leisure and guide services (such as, museum, airports, stores, etc.), and emergency services, among the most important ones.

This thesis presents a …
