The Relationship Between Chronic Health Conditions And Health Literacy, Resiliency And Support/Self-Advocacy In Youth, Mercedes N. Cambric Sep 2017

The Relationship Between Chronic Health Conditions And Health Literacy, Resiliency And Support/Self-Advocacy In Youth, Mercedes N. Cambric

USF Tampa Graduate Theses and Dissertations

Over the past several decades the number of youth living with a chronic health condition has drastically increased. A chronic health condition can be defined as an illness that lasts three months or more that can be controlled but not cured (Centers for Disease Control and Prevention [CDC], 2010). Although there is existing literature on youth with chronic health conditions, there are very few studies that examine the levels of health literacy, resiliency and support/advocacy within this population. The current study is a secondary analysis that utilized data collected from the 37-item Youth Health Literacy and Resiliency Scale (HLRS-Y version) …


Role Of Viruses Within Metaorganisms: Ciona Intestinalis As A Model System, Brittany A. Leigh Sep 2017

Role Of Viruses Within Metaorganisms: Ciona Intestinalis As A Model System, Brittany A. Leigh

USF Tampa Graduate Theses and Dissertations

Marine animals live and thrive in a literal sea of microorganisms, yet are often able to maintain specific associations that are largely dictated by the environment, host immunity and microbial interactions. Animal-associated microbiomes include bacteria and viruses that vastly outnumber host cells, especially in the gut environment, and are considered to be integral parts of healthy, functioning animals that act as a metaorganism. However, the processes underlying the initial establishment of these microbial communities are not very well understood. This dissertation focuses on the establishment of a well-known developmental animal model, Ciona intestinalis (sea squirt), to study the establishment and …


Enhancing The Internet Of Things Architecture With Flow Semantics, Allen Ronald Deserranno Sep 2017

Enhancing The Internet Of Things Architecture With Flow Semantics, Allen Ronald Deserranno

USF Tampa Graduate Theses and Dissertations

Internet of Things (‘IoT’) systems are complex, asynchronous solutions often comprised of various software and hardware components developed in isolation of each other. These components function with different degrees of reliability and performance over an inherently unreliable network, the Internet. Many IoT systems are developed within silos that do not provide the ability to communicate or be interoperable with other systems and platforms. Literature exists on how these systems should be designed, how they should interoperate, and how they could be improved, but practice does not always consult literature.

The work brings together a proposed reference architecture for the IoT …

Lung Ct Radiomics: An Overview Of Using Images As Data, Samuel Hunt Hawkins Sep 2017

Lung Ct Radiomics: An Overview Of Using Images As Data, Samuel Hunt Hawkins

USF Tampa Graduate Theses and Dissertations

Lung cancer is the leading cause of cancer-related death in the United States and worldwide. Early detection of lung cancer can help improve patient outcomes, and survival prediction can inform plans of treatment. By extracting quantitative features from computed tomography scans of lung cancer, predictive models can be built that can achieve both early detection and survival prediction. To build these predictive models, first a detected lung nodule is segmented, then image features are extracted, and finally a model can be built utilizing image features to make predictions. These predictions can help radiologists improve cancer care.

Building predictive models based …


An Examination Of Innovation Idea Selection Factors In Large Organizations, Troy A. Montgomery Sep 2017

An Examination Of Innovation Idea Selection Factors In Large Organizations, Troy A. Montgomery

A review of the innovation literature reveals theoretical models and success factors that pertain to the front end of innovation. However these models and factors fail to offer insight into factors large organizations consider when specifically performing the activity of idea selection. To bridge this gap, a grounded theory method was used to extract knowledge on innovation idea selection from 28 senior executives and innovation directors from 10 different, large organizations (defined as annual revenues greater than $1 billion). Analysis of the interview data resulted in the identification of 5 systemic and 4 implementation factors that large organizations consider when …


Improvising Close Relationships: A Relational Perspective On Vulnerability, Nicholas Riggs Aug 2017

Improvising Close Relationships: A Relational Perspective On Vulnerability, Nicholas Riggs

USF Tampa Graduate Theses and Dissertations

In this dissertation, I study the way couples improvise relationships together. I define improvisation as a kind of performance that leads to an interpretive practice where people develop the meanings of their relationships as they perform. Participating in a performance ethnography, my romantic partner, myself, and three other couples reflect on the way we perform together on stage. Adapting the popular improv performance format “Armando” and utilizing post-performance focus groups, I observe how the couples strive to make meaning together and negotiate a joint-perspective about how they played. Ultimately, I argue that attending to the way a couple improvises their …


Examining How Video-Elicited Reflection Mediates Teacher Candidates’ Beliefs About English Language Learners: A Multiple Case Study, Monica M. Gonzalez Jul 2017

Examining How Video-Elicited Reflection Mediates Teacher Candidates’ Beliefs About English Language Learners: A Multiple Case Study, Monica M. Gonzalez

USF Tampa Graduate Theses and Dissertations

English Language Learners (ELLs) are students who speak a language other than English; they are the fastest growing student population in United States’ (US) public schools and will include over 17 million students by the year 2020 (NCES,2015). The dramatic increase in the ELL student population means that all mainstream classroom teachers will teach at least one ELL within their first year of graduating from a teacher preparation program. However, most US teachers hold misconceptions about ELLs and feel unprepared for ELL instruction (Coady, Harper, & de Jong, 2011). More empirical research is needed to inform teacher preparation programs on …

The Effects Of Loneliness On Consumers’ Digital Engagement With Social Media Ads, Yu Qin Jul 2017

The Effects Of Loneliness On Consumers’ Digital Engagement With Social Media Ads, Yu Qin

USF Tampa Graduate Theses and Dissertations

Social media has become an integral part of consumers’ lives and a popular platform for interactive marketing communication. In an age boasting of unprecedented digital connectivity, loneliness (defined as perceived social isolation) has, paradoxically, becoming widespread, affecting consumers’ preferences for products and brands in the marketplace. The present research extends the feelings-as-information theory and develops a conceptual framework in which loneliness modifies people’s cognitive processing style and induces concrete thinking in the context of evaluating social media messages. Using a mixed methods research approach, I first take a close look through the lens of a qualitative study at what it …

Modeling Of Dynamic Allostery In Proteins Enabled By Machine Learning, Mohsen Botlani-Esfahani Jul 2017

Modeling Of Dynamic Allostery In Proteins Enabled By Machine Learning, Mohsen Botlani-Esfahani

USF Tampa Graduate Theses and Dissertations

Regulation of protein activity is essential for normal cell functionality. Many proteins are regulated allosterically, that is, with spatial gaps between stimulation and active sites. Biological stimuli that regulate proteins allosterically include, for example, ions and small molecules, post-translational modifications, and intensive state-variables like temperature and pH. These effectors can not only switch activities on-and-off, but also fine-tune activities. Understanding the underpinnings of allostery, that is, how signals are propagated between distant sites, and how transmitted signals manifest themselves into regulation of protein activity, has been one of the central foci of biology for over 50 years. Today, the importance …


Agency-Wide Positive Behavioral Interventions And Supports For Residential Care, Rocky Dean Haynes Jr. Jul 2017

Agency-Wide Positive Behavioral Interventions And Supports For Residential Care, Rocky Dean Haynes Jr.

USF Tampa Graduate Theses and Dissertations

Residential care has evolved overtime from a system of supporting indigent children to care for those youth with mental health, behavioral, or medical disability diagnoses. Currently, in the United States there are 57k children involved in the child welfare system with approximately 14% residing in residential care. These systems have a long history of utilizing punishment-based, coercive techniques for managing problem behavior. Although these methods are thought to be further traumatizing for youth who have already been traumatized throughout their lives, the punishment-based techniques are ubiquitous throughout residential care. This study sought to evaluate the feasibility of adopting the School-Wide …

Viruses In Marine Animals: Discovery, Detection, And Characterizarion, Elizabeth Fahsbender

USF Tampa Graduate Theses and Dissertations

Diseases in marine animals are emerging at an increasing rate. Disease forecasting enabled by virus surveillance presents a proactive solution for managing emerging diseases. Broad viral surveys aid in disease forecasting by providing baseline data on viral diversity associated with various hosts, including many that are not associated with disease. However, these viruses can become pathogens due to expansion in host or geographic range, as well as when changing conditions shift the balance between commensal viruses and the host immune system. Therefore, it is extremely valuable to identify and characterize viruses present in many different hosts in a variety of …


The Structure Of Resilience: An Empirical Examination Of Resilience Factors, Matthew R. Grossman Jul 2017

The Structure Of Resilience: An Empirical Examination Of Resilience Factors, Matthew R. Grossman

USF Tampa Graduate Theses and Dissertations

Although most researchers agree that resilience is defined as the extent to which an individual bounces back and recovers from stress and adversity, the field has not yet settled on the underlying structure of the resilience construct; its lower-order factors remain in dispute and undefined. In this study, five of the most prominent resilience measures (i.e., Ego Resilience, Block & Kremen, 1996; The Resilience Scale, Wagnild & Young, 1993; The Connor-Davidson Resilience Scale, Connor & Davidson, 2003; The Resilience Scale for Adults, Friborg, Hjemdal, Rosenvinge, & Martinussen, 2003; The Brief Resilience Scale, Smith, Dalen, Wiggins, & Tooley, 2008) were administered …


A Phenomenological Approach To Clinical Empathy: Rethinking Empathy Within Its Intersubjective And Affective Contexts, Carter Hardy Jul 2017

A Phenomenological Approach To Clinical Empathy: Rethinking Empathy Within Its Intersubjective And Affective Contexts, Carter Hardy

USF Tampa Graduate Theses and Dissertations

This dissertation contributes to the philosophy of empathy and biomedical ethics by drawing on phenomenological approaches to empathy, intersubjectivity, and affectivity in order to contest the primacy of the intersubjective aspect of empathy at the cost of its affective aspect. Both aspects need to be explained in order for empathy to be accurately understood in philosophical works, as well as practically useful for patient care in biomedical ethics.

In the first chapter, I examine the current state of clinical empathy in medicine including professional opinions about empathy, the dominant definition being employed, and the problems that arise from this definition. …


S1p-Mediated Endothelial Barrier Enhancement: Role Of Rho Family Gtpases And Local Lamellipodia, Xun E. Zhang Jul 2017

S1p-Mediated Endothelial Barrier Enhancement: Role Of Rho Family Gtpases And Local Lamellipodia, Xun E. Zhang

USF Tampa Graduate Theses and Dissertations

The endothelial cells lining the inner surface of the tissue capillaries and post-capillary venules form a semi-permeable barrier between the blood circulation and interstitial compartments. The semi-permeable barrier in these vessels is the major site of blood-tissue exchange. A compromised endothelial barrier contributes to the pathological process such as edema, acute respiratory distress syndrome (ARDS) and tumor metastasis. Sphingosine-1-phosphate (S1P), an endogenous, bioactive lipid present in all cells, is a potential therapeutic agent that can restore compromised endothelial barrier function. On the other hand, S1P also has pleotropic effects and can either increase or decrease arterial tone and tissue perfusion …

Problematic Participation And Educational Dilemmas: Ethnography Of The Educational Experiences Of Black Male Youth In Hillsborough County, Florida, Deneia Y. Fairweather

USF Tampa Graduate Theses and Dissertations

In the social sciences, research on black male youth (BMY) experiences in traditional academic settings has been limited to their failure to achieve due to their perceived dysfunctional family structure, gender and ethnic identity, social class, and social structural constraints. Characterized by the anthropological investigation into youth cultural, Legitimate Peripheral Participation (LPP) framework, a theory of practice that includes an alternative framework of learning, and a mixed method approach with an emphasis on capturing the youth perspective through a PhotoVoice process, this research captures a dimension of BMY educational experiences by describing how exclusion from traditional academic settings is produced. …


Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano Jul 2017

Traumatic Brain Injury In Adolescence: The Relationship Between High School Exiting And Future Productivity, Jeffrey S. Garofano

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) is the leading cause of death and disability among children and adolescents. Brain injury survivors are often left with persistent impairments that have the potential to impede daily functioning, delay or prevent the attainment of developmental milestones, and subsequently limit future productivity in adulthood. A shared goal of both neurorehabilitation and the educational system is to prepare youth for a productive adulthood with both systems of care having substantial, yet independent, literature bases regarding factors associated with productivity (e.g., engagement in employment or post-secondary education). It is currently assumed that because type of high school exiting …

Psychosocial Mechanisms Of Outcome In Pediatric Psychiatry, Alessandro S. De Nadai Jul 2017

Psychosocial Mechanisms Of Outcome In Pediatric Psychiatry, Alessandro S. De Nadai

USF Tampa Graduate Theses and Dissertations

Nearly half of all youths experience a mental health disorder at some point during childhood (Merikangas et al., 2010). Pediatric psychopathology is associated with a substantial amount of impairment in the school, social, and home domains, and such symptoms can have adverse impacts on subsequent development (Beauchaine & Hinshaw, 2013; Patel, Flisher, Hetrick, & McGorry, 2007). Fortunately, a number of medications have demonstrated efficacy in treating a number of mental health conditions (Martin, Scahill, & Kratochvil, 2010). Despite these demonstrated effects, treatment response is often incomplete, and the mechanisms by which pharmacotherapy lead to behavior change are not well understood. …
