The Portrayal Of Immigrants In Children's And Young Adults' American Trade Books During Two Peak United States Immigration Eras (1880-1930 And 1980-2010s), Rina Roula Bousalis

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Although immigrants are an integral part of the nation's founding and history, it is unclear how they have been historically portrayed in children's and young adults' American trade books, especially at the turn of the 20th century. This study offers a critical and comparative analysis focusing on the historical evolution, depiction of immigrants, and authors' perspectives of selected trade books written during two peak United States immigration eras (1880-1930 and 1980-2010s).

Utilizing a discourse analysis approach, this study examined how first-generation immigrants were portrayed in selected trade books and how various themes and representations may have affected students and …

Development Of A New Guidewire Torque Device, Erika Rigaud

USF Tampa Graduate Theses and Dissertations

Guidewires have been used in many operating rooms by vascular surgeons to assist them in positioning and maneuvering through a tortuous stenosis or lesion to a desired location, and to be used as a guide for the implantation of a catheter. Surgeons are tasked with having to insert a guidewire inside a small cavity, which requires a high level of skill and patience. The insertion of the guide wire is controlled by a torque device, which allows a surgeon to advance, rotate and grip the wet hydrophilic coating of the guidewire. Despite its many advantages, the torque device does, in …

Novel Models And Efficient Algorithms For Network-Based Optimization In Biomedical Applications, Seyed Javad Sajjadi

USF Tampa Graduate Theses and Dissertations

We introduce and study a novel graph optimization problem to search for multiple cliques with the maximum overall weight, to which we denote as the Maximum Weighted Multiple Clique Problem (MWMCP). This problem arises in research involving network-based data mining, specifically, in bioinformatics where complex diseases, such as various types of cancer and diabetes, are conjectured to be triggered and influenced by a combination of genetic and environmental factors. To integrate potential effects from interplays among underlying candidate factors, we propose a new network-based framework to identify effective biomarkers by searching for "groups" of synergistic risk factors with high predictive …

Individual And Partner Characteristics Associated With Genital Herpes Disclosure And The Relationship Between Disclosure Outcomes, Rejection, And Future Intentions To Disclose, Jaime L. Myers

USF Tampa Graduate Theses and Dissertations

Background: Genital herpes is one of the most common sexually transmitted infections in the United States. As genital herpes is incurable and contagious, individuals with genital herpes face the decision to disclose their status to potential sexual partners with each new relationship formed. Such disclosure places individuals with genital herpes in a position to face rejection, which is commonly reported as one of the most concerning aspects of having genital herpes. The present study seeks to further understand the nature of genital herpes disclosure by addressing two core aims: 1) to understand determinants of and reasons for disclosure and non-disclosure …

A Multi-Proxy Approach To Understanding Abrupt Climate Change And Laurentide Ice Sheet Melting History Based On Gulf Of Mexico Sediments, Clare Carlisle Williams

USF Tampa Graduate Theses and Dissertations

During the last deglaciation (ca. 24-10 ka thousand years ago (ka)), the North American Laurentide Ice Sheet (LIS) was a major source of meltwater to the Arctic Ocean, North Atlantic Ocean, and the Gulf of Mexico (GOM), and it is hypothesized that meltwater routing played an important role in regulating Late Quaternary millennial-scale climate variability, via its influence on Atlantic Meridional Overturning Circulation (AMOC). For example, the meltwater routing hypothesis predicts that a rerouting of meltwater from the GOM to the North Atlantic and/or Arctic Oceans resulted in a decrease of North Atlantic Deep Water (NADW) formation and subsequent cooling …

The Problems And Potentials In Haunted Maternal Horror Narratives, Sarah Laura Novak

USF Tampa Graduate Theses and Dissertations

This thesis will examine the representation of motherhood in horror cinema in order to discuss the problems and potentials of repeated domestic traditions. While maternal horror narratives impose gender roles based on heterosexual hegemonic biases, some of these films also examine the feminine experience and criticize the patriarchal institutional structures that affect domesticity and femininity. If we discuss these promising features, we can build on the implied trajectories, and engender more representation of marginalized experience in order to seek out new methods of cultural stabilization and unity. This proposal relies on Jacques Derrida's theory of hauntology, which addresses past and …

Biomaterial Testing Methodology For Long-Term In Vivo Applications: Silicon Carbide Corrosion Resistance, Biocompatibility And Hemocompatibility, Maysam Nezafati

USF Tampa Graduate Theses and Dissertations

Biomedical devices that function in-vivo offer a tremendous promise to improve the quality of life for many who suffer from disease and trauma. The most important consideration for these devices is that they interact with the physiological environment as designed without initiating a deleterious inflammatory response. ISO 10993 outlines the current international guideline for investigating the biocompatibility of such devices. Numerous groups report the use of ISO 10993 as the basis for their experimental evaluation of candidate materials for neuroprosthetics, as well as other biomedical devices, however most of these reports fail to completely comply with the standard. This leads …

USF Tampa Graduate Theses and Dissertations

Abstract

Faith-based school-family-community partnerships have been a federal mandate over the past decade, yet little has been written about the outcomes of these faith-based partnerships. A need exists to understand if the potential in these faith-based partnerships is indeed realized in positive outcomes for students and schools. The purpose of this study was to evaluate a faith-based school-family-community partnership, Just Love. Just Love is a faith-based school-family-community partnership between a large suburban church and a Title 1, urban elementary school, Charisma Elementary School (Charisma ES; pseudonym). It was implemented in what is considered a "failing school". Just Love's purpose was …

Evidence-Based Practice Attitudes, Knowledge And Perceptions Of Barriers Among Juvenile Justice Professionals, Esther Chao Mckee

USF Tampa Graduate Theses and Dissertations

This mixed methods study examined the attitudes, knowledge and perceptions of barriers toward Evidence-Based Practice (EBP) among Florida Juvenile Justice Service Professionals (JJSP). Previous research established individual factors such as age, gender, years of professional experience and educational attainment are related to attitudes and perceptions of barriers among social service and mental health professionals, but scant research has been conducted among juvenile justice providers (Aarons 2004, 2010; Rubin & Parrish, 2007, 2012; Jette et al., 2003). Most individual factors were found to have no significant effect on attitude and knowledge scores within this population with exception of gender and major …

Cancer And Infection, Kathleen Hope Plummer

USF Tampa Graduate Theses and Dissertations

E. coli is the most frequently isolated Gram negative pathogen from bacteremia in cancer patients and is repeatedly recovered from many other extraintestinal illnesses. These infections are commonly endogenous in nature and interfere with the treatment of cancer resulting in increased healthcare costs, morbidity, and mortality rates. Cancer and the treatments related to cancer cause alterations in the microbiome of the gut and other organs. Despite this point, there is a serious lack of knowledge about the genetic types of E. coli infecting cancer patients. This gap results in vague prevention strategies and limited treatment options for cancer patients. Multi …

The Development And Initial Validation Of An Instrument Measuring The Cognitive Domain Of Intercultural Maturity, Melanie Lynne Wicinski

USF Tampa Graduate Theses and Dissertations

Abstract

Through a two-phase process an instrument was created to measure the cognitive domain as proposed by King and Baxter Magolda in their Developmental Model of Intercultural Maturity (2005). The first phase involved expert panels who identified the competencies which exist in the cognitive domain, identified situations which might exist between individuals from different cultures, validated scenarios created from the identified situations, and created responses which corresponded to the three developmental levels (Initial, Intermediate, and Mature) defined in the Developmental Theory of Intercultural Maturity.

Within the second phase, the created instrument was administered to 371 individuals representing eight geocultural world …

Evolution And Equilibration Of Artificial Morphologic Perturbations In The Form Of Nearshore Berm Nourishments Along The Florida Gulf Coast, Katherine Emily Brutsché

USF Tampa Graduate Theses and Dissertations

Inlets and channels are dredged often to maintain navigation safety. It is beneficial to reintroduce the dredged material back into the littoral system, in the form of beach or nearshore nourishments. Nourishment in the nearshore is becoming an increasingly utilized method, particularly for dredged material that contains more fine sediment than the native beach. This research examines the morphologic evolution of two different nearshore nourishments. A nearshore berm was constructed at Fort Myers Beach, Florida using mixed-sized sediment dredged from a nearby channel. The nearshore berm was placed in water depths between 1.2 and 2.4 m with the berm crest …

Testing The Correlation Between Response Latency, Derivation, And Complexity, Jeffrey Ryan Oliver

USF Tampa Graduate Theses and Dissertations

This study investigates the constructs of Derivation and Complexity and how they relate to latency. Derivation and Complexity are theoretical constructs that have been posited as two of the main factors in differences in latency to responding in implicit measures such as the Implicit Relational Assessment Procedure (IRAP) and the Implicit Association Task (IAT). This study trained participants to relate two groups of novel stimuli in a linear fashion and then tested their latency to responding to derived relations (relations based on previously trained relations, but not directly trained themselves). The study then analyzed participant's latency to responding after dividing …

Analysis was performed using Microsoft Excel with Solver and Matrix.xla add-ins and automated with VBA code. Major movements and time intervals between movements were calculated by locating the area of maximum pressure on each hemi-buttock for …

Can The Usa National Weather Service Heat Index Substitute For Wet Bulb Globe Temperature For Heat Stress Exposure Assessment?, Ivory Iheanacho

USF Tampa Graduate Theses and Dissertations

Heat stress occurs when the body cannot adequately cool itself due to the combined contributions of metabolic heat, environmental factors and clothing. Heat stress found in the workplace puts employees at risk of developing heat-related illnesses, disorders and could be fatal. The wet bulb globe temperature (WBGT) index is the current method used to assess environmental contributions to heat stress in an occupational setting. The purpose of this thesis was to explore whether the National Weather Service's Heat Index (HI) could substitute for the WBGT Index during occupational heat stress exposure assessment. The possibility of using the HI for heat …

The Relationship Of Affective Domains And Cognitive Performance In Paramedic Students, Katie J. Lyman

USF Tampa Graduate Theses and Dissertations

No universal approach for application procedures has been established for paramedic curriculum programs. The field of pre-hospital, Emergency Medical Services (EMS) has evolved quickly from its inception to present date. The educational components of EMS are still in their infancy and lack evidence-based protocols (Drees, 2006). Predicting success in an allied health program typically concentrates on some type of academic instrument. The use of personality inventories has been underexplored; however, literature reveals they may be more reliable in determining academic and employment success compared with other non-cognitive tools (Groves, Gordon, & Ryan, 2007; Marrin et al., 2004; McManus & Richards, …

Negative Reinforcement In Infant Care Simulation: Alternative Caregiver Responses To Prevent Child Abuse, Miriam Tye

USF Tampa Graduate Theses and Dissertations

This study was conducted to replicate and extend previous research on infant caregiver behavior by demonstrating negative reinforcement of infant caregiver behavior in response to crying and teaching appropriate care responses under conditions of inconsolable crying. A computerized infant simulator was used to create a laboratory simulation of infant caregiving. In Study 1, participants were exposed to negative reinforcement conditions and an extinction condition. In the negative reinforcement condition, participants engaged in caregiving responses to escape from the cry. In the extinction condition, the cry was inescapable and two of three participants stopped engaging in the previously reinforced caregiving response. …

Analysis Of Critical Behavior In Magnetic Materials, Dustin David Belyea

USF Tampa Graduate Theses and Dissertations

This work contains a broad study of a variety of magnetic materials undergoing second order phase transitions. In general this leads to an overall increase in information and analytical methods to further the field of magnetocalorics. Specifically, critical aspects of magnetocaloric materials were compared within systems in relation to structure, stoichiometry, magnetic minority phases and magnetic contaminants. Detailed analyses were developed to quantify techniques which were in the past used mainly in a qualitative way, leading to a more complete understanding of how critical phenomena impacts the magnetocaloric response.

USF Tampa Graduate Theses and Dissertations

Abstract

This study focuses on the process of communication between government agencies and the public during crisis situations, and the development of an effective response strategy when a significant threat to public health and/or safety is believed to exist. My specific research interests are (1) the nature of the decision-making process that influences the communicative choices made during such events, and (2) how decision-makers make sense of an evolving, ambiguous, and unpredictable situation, in order to establish credibility with the public, determine the appropriate response strategy, and gain the public's trust in order to influence its behavior. This is a …

Characterization Of Waste Anesthetic Gas Exposures To Veterinary Workers In The Tampa Bay Area, Kyle Vogel

USF Tampa Graduate Theses and Dissertations

Veterinarians routinely conduct surgical operations on animals while veterinary technicians administer anesthetic gas to sedate the animal prior to an operation. One commonly used anesthetic agent in veterinary clinics is isoflurane. Veterinary workers have the potential to be exposed to this gas during surgical operations. The Occupational Safety and Health Administration (OSHA) does not have a specific Permissible Exposure Limit (PEL) for isoflurane, however The National Institutes for Health (NIH) does advise that workers should not be exposed to isoflurane in concentrations exceeding 2 parts per million (ppm) for an 8 hour Time Weighted Average (TWA).

Animal clinics vary in …

The Use Of Behavior Specific Praise And The Caught Being Good Game To Improve Class-Wide Behavior, Emily Rhodes

USF Tampa Graduate Theses and Dissertations

This study evaluated the relative contributions of behavior specific praise statements (BSPS) and the Caught Being Good Game (CBGG) on class-wide appropriate behaviors and examined teacher use of BSPS and corrective feedback. It also evaluated if changes in class-wide behaviors are maintained during follow-up and generalized to non-target academic periods. Data on teacher use of BSPS were also collected during follow-up and generalization probes to examine if the teachers continued to use BSPS during follow-up and generalize their use of BSPS to non-target academic periods. A multiple-baseline design across classrooms with an ABC sequence was used to evaluate the outcomes …

The Influence Of Individual Differences On Emotional Processing And Emotional Memory, Patricia Lynn Johnson

USF Tampa Graduate Theses and Dissertations

Emotional material is better remembered than neutral material and some suggest this is reflected in different Event Related potentials (ERPs) to affective stimuli by valence. Inconsistent results may be due to individual differences, specifically the behavioral inhibition/behavioral activation (BIS/BAS) motivational system. This study sought to examine the relationship between motivational systems, emotional memory, and psychophysiological response to emotional pictures. While using EEG recording, subjects were shown 150 affective pictures and given a recall and yes/no recognition task after a 20 and 30-minute delay, respectively. Overall, differences were found by valence, but not consistently based on individual trait. Controlling for arousal …

Insights Into The Epitaxial Relationships Between One-Dimensional Nanomaterials And Metal Catalyst Surfaces Using Density Functional Theory Calculations, Debosruti Dutta

USF Tampa Graduate Theses and Dissertations

This dissertation involves the study of epitaxial behavior of one-dimensional nanomaterials like single-walled carbon nanotubes and Indium Arsenide nanowires grown on metallic catalyst surfaces. It has been previously observed in our novel microplasma based CVD growth of SWCNTs on Ni-Fe bimetallic nanoparticles that changes in the metal catalyst composition was accompanied by variations in the average metal-metal bond lengths of the nanoparticle and that in turn, affected nanotube chirality distributions. In this dissertation, we have developed a very simplistic model of the metal catalyst in order to explain the nanotube growth of specific nanotube chiralities on various Ni-Fe catalyst surfaces. …

Development And Assessment Of Self-Explaining Skills In College Chemistry Instruction, Adrian Villalta-Cerdas

USF Tampa Graduate Theses and Dissertations

The prevalent trend in chemistry instruction relies on what has been described as the classroom game. In this model, students take a passive role and the instructor does all the explaining (thinking), and learning is trivialized to knowing the correct answers (memorizing) and being able to produce them when prompted (regurgitating). The generation of explanations is central to scientific and technological development. In the process of figuring out explanations, the generation of inferences relies on the application of skills associated with scientific behaviors (e.g., analytical reasoning and critical thinking). The process of explanation generation causes a deeper analysis and revision …

Novel Cell Cycle Proteins In Apicomplexan Parasites, Carrie Butler

USF Tampa Graduate Theses and Dissertations

Apicomplexans are responsible for major human diseases such as toxoplasmosis caused by Toxoplasma gondii (T. gondii) and the deadliest form of malaria caused by Plasmodium falciparum (P. falciparum). The genomes of these pathogens are now sequenced ushering in a new era of drug development. A major hurdle to exploiting this genome resource is that a large number of the encoded genes are "hypotheticals" and have yet to be characterized. Hypothetical proteins comprise roughly half of the predicted gene complement of T. gondii and P. falciparum and represent the largest class of uniquely functioning proteins in these parasites.

Following the idea …
