Was It Something They Said? Stand-Up Comedy And Progressive Social Change, David M. Jenkins

USF Tampa Graduate Theses and Dissertations

From our earliest origins in every civilization across the globe, comic performances have fulfilled an important social function. Yet stand-up comedy has not attracted the serious academic inquiry one might expect. This dissertation argues that in the absence of public intellectuals stand-up comics are important to how we talk about and negotiate complicated issues like gender and race. These comic texts are sites of cultural critique, public discourse, tools for articulation, a means of persuasion, and serve to galvanize communities.

This dissertation argues that stand-up comedy performances are a vital part of modern American intellectual and social life and are …

Equifinality And Multifinality In Psychopathology: Can Cognitive And Emotional Processes Differentiate Internalizing, Externalizing, And Co-Occurring Psychopathology, Brittany Jordan-Arthur

USF Tampa Graduate Theses and Dissertations

Despite our knowledge of environmental risk factors for psychopathology, the equifinality and multifinality observed in the extant literature reveals how little is known about the role of these risk factors in the development of psychopathology. The purpose of this study was to identify processes that differentiate internalizing, externalizing and co-occurring psychopathology. Specifically, emotion identification skill and cognitive appraisal style were examined as processes where individual differences may contribute to the development of mental illness. To date no study has been conducted to examine whether emotion identification and appraisal style may differentiate forms of internalizing, externalizing and co-occurring psychopathology and lack …

Structure-Function Analysis Of The Dna Damage Repair Complex Str In Saccharomyces Cerevisiae, Jessica Ashley Kennedy

USF Tampa Graduate Theses and Dissertations

The RecQ family of helicases has been termed the “Caretakers of the Genome,” and rightfully so. These proteins are highly conserved from bacteria to humans and have been implicated in functions from homologous recombinatorial repair to damage checkpoint response to telomere maintenance and more. Mutant genes of three of the human RecQ helicases lead to syndromes characterized by a high incidence of cancer, premature aging and early death. Despite their implications in several biological functions and importance to the integrity of the human genome and suppression of cancer, many aspects of the RecQ family structure and function remain unknown. To …

How You Categorize Influences How Helpful You Are: The Effect Of Categorization Mindset On Consumers’ Social Decisions, Hsiao-Ching Kuo

USF Tampa Graduate Theses and Dissertations

This dissertation demonstrates how categorization mindsets (introduced by Ulkumen et al., 2010) moderate the altruistic behavior of consumers in decisions that have consequences to others besides oneself. Categorization mindset refers to a way of thinking about options, and is induced by simple sorting or categorization tasks. Ulkumen et al. (2010) has shown that mindsets can be unidimensional (in terms of being focused on a single, salient dimension) or multidimensional (in that both salient and non-salient dimensions are processed). Across three experiments, this dissertation finds that a multidimensional mindset (compared to a unidimensional mindset) enhances the preference for other-oriented options among …

USF Tampa Graduate Theses and Dissertations

This dissertation is a compilation of research and theoretical papers based on the affordances of multimodal literacies for marginalized learners and for pre-service teachers’ developing conceptualizations of literacy. Through a transdisciplinary lens, the author considers complex issues presented in traditional, print-based learning environments that potentially marginalize learners in their developing abilities to become successful participants in the multiple literacies in the real world.

Three studies focus on pre-service teachers and their developing understanding of effective literacy-related classroom practices. Chapter Three explores potential affordances of a multimodal learning environment for pre-service teachers with self-identified reading difficulties. The phenomenological study highlights differing …

The Role Of Anxiety Sensitivity In The Relationship Between Posttraumatic Stress Symptoms And Negative Outcomes In Trauma-Exposed Adults, Brittany Belle Kugler

USF Tampa Graduate Theses and Dissertations

Background: The development of posttraumatic stress symptoms (PTS) following a traumatic event is related to significant functional impairment, diminished quality of life, and physical health issues. Yet it is not entirely clear why some traumatized individuals experience negative outcomes while others do not. The purpose of this study is to determine the role of several influential factors related to PTS severity and negative outcomes, such as diminished quality of life and physical health issues, following traumatic events. Method: One hundred and twenty-two trauma-exposed adults were recruited through the University of South Florida’s SONA system and through flyers on campus. Subjects …

Investigation Of Post-Translational Modifications In Staphylococcus Aureus, Christina Nadia Krute

USF Tampa Graduate Theses and Dissertations

The work presented herein details post-translational modifications (PTMs) in Staphylococcus aureus that are involved in mediating the stress response and normal cellular processes. The first PTM that was investigated is regulated intramembrane proteolysis (RIP) for the activation of the ECF sigma factor σS. We achieved this by analyzing the role of the site-1 protease, which we termed “putative regulator of sigmaS” (PrsS), as it is predicted to be the first enzyme in the RIP cascade, leading to the activation of σS. It was determined that the putative site-1 protease, prsS, mimics transcriptional profiles of sigS; with expression low in all …

System Threats And Gender Differences In Sexism And Gender Stereotypes, Sophie Lois Kuchynka

USF Tampa Graduate Theses and Dissertations

In the United States, women’s persistent gains in structural power may cause backlash among those motivated to preserve the status quo. The proposed study examines the conditions that prompt men and women to endorse sexism and promote gender stereotypes. System justification theory proposes that people are motivated to justify the socio-political system that governs them and threats to the stability of their system can increase individual’s motivated defenses. I expect men to show the strongest motivated defenses when the hierarchy is threatened or viewed as unstable, because to protect group-based interests men will reinforce the legitimacy of the system through …

Schreibersite: Synthesis, Characterization And Corrosion And Possible Implications For Origin Of Life, Nikita Latesha La Cruz

USF Tampa Graduate Theses and Dissertations

We present study of the synthesis and reactions of an analog of the meteoritic mineral schreibersite with formula (Fe,Ni)3P, believed to be a prebiotic source of reactive phosphorus that may have prompted the formation of phosphorylated biomolecules near the time of the origin of life (Pasek and Lauretta, 2005). The mineral was synthesized by mixing stoichiometric proportions of elemental iron, nickel and phosphorus and heating in a tube furnace at 820°C for approximately 235 hours under argon or under vacuum, a modification of the method of Skála and Drábek (2002). The mineral was characterized using X-ray diffractometry (XRD), X-ray photoelectron …

Experimental Reporting And Networks Of Political Information: Lorenzo Magalotti's Framing Of Courts And Nature, Bradley L'Herrou

USF Tampa Graduate Theses and Dissertations

This thesis explores changes in experimental reporting during the scientific revolution of the seventeenth century. In particular, I examine and compare some of the works of Count Lorenzo Magalotti, namely the Saggi di Naturali Esperienza or Essays on Natural Experiments and the Relazione d'Inghilterra. In 1667, as secretary of the Accademia del Cimento – the Tuscan experimental academy founded in 1657 – Magalotti (1637-1712) authored the Saggi, a collection of experimental reports. These reports included extensive written descriptions of experiments along with dozens of engravings depicting the instruments custom-made for the experiments. Magalotti also served as ambassador and agent of …

The Relationship Between Nurses' Emotional Intelligence And Patient Outcomes, Mary Kutash

USF Tampa Graduate Theses and Dissertations

Heart Failure readmissions (HFR) significantly contribute to all cause hospital readmissions rates. Current evidence on the effectiveness of interventions for reduction of HFR is inconclusive. Recent research suggests that nurses’ emotional intelligence (EI) may be associated with better patient outcomes.

The purpose of this study was to examine if nurses’ EI is significantly related to HFR and if that relationship is mediated through patient satisfaction with care. One hundred and thirty six Registered Nurses were recruited from 11 in-patient units at a large teaching hospital in the south eastern United States. Two surveys were mailed to eligible participants; the Bar-On …

Is There An Economic Case For Investing In Nursing Care – What Does The Literature Tell Us?, Diane E. Twigg, Helen Myers, Christine Duffield, Margaret Giles, Gemma Evans

Research outputs 2014 to 2021

Aim

To determine the cost effectiveness of increasing nurse staffing or changing the nursing skill mix in adult medical and/or surgical patients?

Background

Research has demonstrated that nurse staffing levels and skill mix are associated with patient outcomes in acute care settings. If increased nurse staffing levels or richer skill mix can be shown to be cost-effective hospitals may be more likely to consider these aspects when making staffing decisions.

Design

A systematic review of the literature on economic evaluations of nurse staffing and patient outcomes was conducted to see whether there is consensus that increasing nursing hours/skill mix is …

The Meaning Of Stories Without Meaning: A Post-Holocaust Experiment, Tori Chambers Lockler

USF Tampa Graduate Theses and Dissertations

Dissonance exists in efforts to communicate about suffering and despair. Showcasing common societal flawed reactions to despair begs for discourse to create a more communicatively healthy response. Attempting to communicate the suffering of others and feeling like I was failing at that goal led to my own suffering. Using writing as a method of personal healing created an intersection of personal narratives of suffering and victim’s narratives (which can arguable only allow for the co-opting of the story and narcissism). Grappling with the limits of writing to heal provided a lens to see the victim’s narratives in such a way …

A Planar Pseudo-Rigid-Body Model For Cantilevers Experiencing Combined Endpoint Forces And Uniformly Distributed Loads Acting In Parallel, Philip James Logan

USF Tampa Graduate Theses and Dissertations

This dissertation describes the development and effectiveness of a mathematical model used to predict the behavior of cantilever beams whose loading conditions include parallel combinations of evenly distributed loads and endpoint forces. The large deflection of cantilever beams has been widely studied. A number of models and mathematical techniques have been utilized in predicting the endpoint path coordinates and load-deflection relationships of such beams. The Pseudo-Rigid-Body Model (PRBM) is one such method which replaces the elastic beam with rigid links of a parameterized pivot location and torsional spring stiffness. In this paper, the PRBM method is extended to include cases …

Historical And Current Population Patterns Of The Staghorn Coral (_Acropora Cervicornis_) In Dry Tortugas National Park, Kaitlyn Lizza

USF Tampa Graduate Theses and Dissertations

Acropora cervicornis was once one of the dominant reef building corals of the Caribbean, Florida Keys, and Dry Tortugas (DRTO), but since the 1970’s populations have been decimated throughout their geographic range. Recently, a repopulation was documented through detailed benthic surveys conducted by the U.S. Geological Survey at three locations (Pulaski Shoal, East Key, and Loggerhead Key) within DRTO. Benthic surveys using the U.S Geological Survey’s Along-Track Reef Imaging System (ATRIS) revealed hundreds of previously undocumented colonies.

These discoveries have provided a unique data-set, allowing a comparison between the historical (1883, 1976) and contemporary distributions (2009, 2011) of A. cervicornis. …

Effects Of Solids Retention Time And Feeding Frequency On Performance And Pathogen Fate In Semi-Continuous Mesophilic Anaerobic Digesters, Nathan Daniel Manser

USF Tampa Graduate Theses and Dissertations

Anaerobic digestion is a biochemical process in which organic carbon is biodegraded in an oxygen free environment through a microbial consortium. Engineered biological systems used for resource recovery often utilize anaerobic digestion to treat anthropogenic organic wastes by reclaiming the carbon as energy (methane gas) and a soil amendment (biosolids). Small-scale, or household, semi-continuous anaerobic digesters have been used in developed and developing countries for many decades to produce biogas from human and livestock waste, which is used for heating, lighting, and cooking. This application has been shown to improve the quality of life of the user. Although there is …

Rapid Root Elongation By Phreatophyte Seedlings Does Not Imply Tolerance Of Water Table Decline, Caroline A. Canham, Raymond H. Froend, William D. Stock

Research outputs 2014 to 2021

Key message Despite high rates of root elongation during phreatophyte establishment once connection to groundwater has occurred and leaf area develops, seedlings demonstrate limited capacity for root elongation in response to groundwater decline.

Abstract In a water-limited environment, rapid root elongation immediately after germination can be critical for a plant to reach deeper water sources such as a water table to avoid water deficit stress. However, once plants have accessed a water table, their continued survival may depend on their ability to adapt their root distribution to changes in the depth to a water table. In glasshouse experiments using two …

Hclp46 Increases Smad3 Protein Stability Via Inhibiting Its Ubiquitin-Proteasomal Degradation, Yingying Xing, Qiaoyun Chu, Run Feng, Wei Wang, Lixin Liu, Zhongbing Lu

Research outputs 2014 to 2021

hCLP46 (human CAP10-like protein 46 kDa) was initially isolated and identified from human acute myeloid leukemia transformed from myelodysplastic syndrome (MDS-AML) CD34⁺ cells (Teng et al., 2006) and we demonstrated previously that hCLP46 is abnormally expressed in many hematopoietic malignancies (Wang et al., 2010). Studies fromits Drosophila homolog, Rumi, suggested that Notch is a potential target of hCLP46 (Acar et al., 2008). We also found that overexpression of hCLP46 enhances Notch activation and regulates cell proliferation in a cell type-dependent manner (Ma et al., 2011; Chu et al., 2013). However, hCLP46^−/− embryos show more severe phenotypes …

Research outputs 2014 to 2021

The increased connectivity to existing computer networks has exposed medical devices to cybersecurity vulnerabilities from which they were previously shielded. For the prevention of cybersecurity incidents, it is important to recognize the complexity of the operational environment as well as to catalog the technical vulnerabilities. Cybersecurity protection is not just a technical issue; it is a richer and more intricate problem to solve. A review of the factors that contribute to such a potentially insecure environment, together with the identification of the vulnerabilities, is important for understanding why these vulnerabilities persist and what the solution space should look like. This …

The Role Of Apoe-Ε4 And Beta Amyloid In The Differential Rate Of Recovery From Ect : A Review, T. A. Sutton, Hamid R. Sohrabi, Stephanie Rainey-Smith, S. M. Bird, M. Weinborn, Ralph Martins

Research outputs 2014 to 2021

Individual biological differences may contribute to the variability of outcomes, including cognitive effects, observed following electroconvulsive treatment (ECT). A narrative review of the research literature on carriage of the apolipoprotein E ε4 allele (APOE-ε4) and the protein biomarker beta amyloid (Aβ) with ECT cognitive outcome was undertaken. ECT induces repeated brain seizures and there is debate as to whether this causes brain injury and long-term cognitive disruption. The majority of ECT is administered to the elderly (over age 65 years) with drug-resistant depression. Depression in the elderly may be a symptom of the prodromal stage of Alzheimer’s disease …

The Nature Of Attachment Relationships And Grief Responses In Older Adults: An Attachment Path Model Of Grief, Yan Kho, Robert T. Kane, Lynn E. Priddis, Josephine Hudson

Research outputs 2014 to 2021

Background: Various researchers have theorized that bereaved adults who report non-secure attachment are at higher risk of pathological grief. Yet past findings on avoidant attachment representations and grief have yielded limited and contradictory outcomes. Little research has been conducted with older adults to identify the psychological processes that mediate between self-reported attachment representations and the patterns of grief.

Objective: To examine the impacts of avoidant attachment and anxious attachment dimensions on emotion and non-acceptance, in response to the loss of a conjugal partner, and the mediating effect of yearning thoughts.

Design: Men (N = 21) and women (N …

Failure Of Science, Death Of Nature, H.F. Recher

Research outputs 2014 to 2021

As a people, Australians have lost contact with the world of nature, Risking the collapse of civilization. One factor in the alienation of nature in Australia is the failure of the scientific community to take responsibility for the technology created by the knowledge generated from scientific research. Science has failed to protect Australia's flora and fauna. Scientists must communicate more widely with society, but need to be educated on how to communicate and on their ethical responsibilities to others and other species. Government needs to show leadership in environmental management and nature conservation, while conservationists need to 'invert the paradigm', …
