For the purposes of my study, I define this type of friendship as those who have known me for at least two years and with whom I communicate regularly. These are friends who tend to know a variety of personal details about me, ranging from superficial to private and trivial to essential. I use autoethnography to ground the study in my lived experience. By doing so, I present intimate accounts of my communication with others across my lifespan to function as background …

Deep Reinforcement Learning Based Optimization Techniques For Energy And Socioeconomic Systems, Salman Sadiq Shuvo

USF Tampa Graduate Theses and Dissertations

Optimization, which refers to making the best or most out of a system, is critical for an organization's strategic planning. Optimization theories and techniques aim to find the optimal solution that maximizes/minimizes the values of an objective function within a set of constraints. Deep Reinforcement Learning (DRL) is a popular Machine Learning technique for optimization and resource allocation tasks. Unlike the supervised ML that trains on labeled data, DRL techniques require a simulated environment to capture the stochasticity of real-world complex systems. This uncertainty in future transitions makes the planning authorities doubt real-world implementation success. Furthermore, the DRL methods have …

Academic Advisors' Perceptions Of Implicit Bias In Interactions With Students: An Exploratory Case Study, Bobby A. Brown

USF Tampa Graduate Theses and Dissertations

Academic advisors are crucial to the success of students who attend higher education institutions (e.g., Himes, 2014; Paul & Fitzpatrick, 2015; Smith, 2005). They guide students to complete their degrees in a timely progression and serve as a contact for students to help increase a sense of belonging on college campuses. Higher education literature presented evidence that suggested academic advisors demonstrate implicit bias while interacting with students they advise (e.g., Bahr, 2008; Grau & Zotos, 2016). Implicit bias may expose academic advisors to errors in judgment and decision making while assisting students. The purpose of this qualitative case study was …

I'Ll Make A Man Out Of You: Precarious Manhood Beliefs Among Heterosexual-Cisgender Men And Queer Men, Serena L. Wasilewski

USF Tampa Graduate Theses and Dissertations

Traditional masculine gender stereotypes often suggest that men should be strong, assertive, and athletic, and these stereotypes promote men’s dominance in society and gender inequality. Endorsement of masculine stereotypes may also contribute to heterosexual men being more prejudiced against queer men. Queer men experience unique difficulties in their quest to abide by social norms defining manhood. Research using the precarious manhood theory suggests that manhood is difficult to obtain and even more challenging to maintain. Given the emerging nature of precarious manhood studies, little is known about young men’s perceptions of the precarious nature of manhood and how this may …

Testimonios Of Civic Pedagogy: Developing Critical Literacy Skills Using Civics And Holocaust Studies, Tameka Parenti

USF Tampa Graduate Theses and Dissertations

Civics using Holocaust Studies offer a variety of pedagogical advantages. Regardless of the topic, Holocaust events can be used to build critical analytical skills and cultivate essential literacy skills about the social world. Further, the Holocaust can be used to introduce and grapple with the complex/abstract ideas of the civics content. Given the relationship that social studies has to critical literacy development, civics used in conjunction with Holocaust resources present teacher(s) (educators) with the opportunity to explore (theoretical) concepts foregrounding manifold relationships making up the social world.

This research aimed to examine how secondary students connect to the social world …

Frequency Domain Diffuse Optics Spectroscopies For Quantitative Measurement Of Tissue Optical Properties, Sadhu Moka

USF Tampa Graduate Theses and Dissertations

Tissue oxygen saturation, blood flow and blood volume are physiological bio-markers of tissue health. Diffuse Optical Spectroscopy(DOS) and Diffuse Correlation Spectroscopy (DCS) are two complementary approaches to measure tissue oxygen saturation and blood flow respectively. Quantitative Diffuse Optical Spectroscopy (DOS) uses multi-spectral intensities of near-infrared light that have been modulated at RF frequencies to estimate static tissue optical properties and hence concentrations of oxygenated and de-oxygenated hemoglobin. Diffuse Correlation Spectroscopy estimates tissue dynamics - i.e., blood flow, by measuring temporal intensity auto-correlation function of backscattered light diffusing through the tissue. Conventionally, DCS instruments use coherent light sources with constant intensity. …

Reducing Instrumentation Barriers Of Diffuse Correlation Spectroscopy For Low-Cost Deep Tissue Blood Flow Monitoring, Arindam Biswas

Make The Effort, Take The Time: A Qualitative Study Of Inclusive Managerial Interactions At A Canadian Energy Company, Gregory M. Kober

USF Tampa Graduate Theses and Dissertations

Workplace inclusion both maximizes the benefits of a diverse workforce and simultaneously reduces its negative consequences. However, a majority of the inclusion research takes an explicit or implicit management-focused perspective. This is problematic because management has more power than employees and executives are usually exemplars of the dominant organizational culture. In order to be more holistic, inclusion research should be much more deeply informed by a subordinate-centered understanding of workplace inclusiveness. Those with less power, those who are minoritized, and those who are marginalized have critical perspectives that must be brought to bear on the construct of workplace inclusivity.

This …

Information Dissemination And Perpetual Network, Harshit Srivastava

USF Tampa Graduate Theses and Dissertations

Social networks have attracted increasing attention from both physical and social scientists. Social networks are essential elements in societies, serving as channels for exchanging various benefits, such as innovation, information, and social support. Moreover, research in social networks helps explain macro-level social phenomena, such as social polarization and social contagion. An understanding of social networks has significant implications, such as improving social welfare and political participation. Modeling social network formation has typically employed game theory or agent-based modeling. These studies typically propose simple and tractable micro-level rules for link formation mechanisms and show that these rules have implications for known …

Stochastic Models For Resilience Assessment And Improvement, Weimar Ardila Rueda

USF Tampa Graduate Theses and Dissertations

Resilience refers to the ability of a system to absorb and mitigate the impact of potential disruptions and return to normal operational conditions. The above notion of resilience allows us to distinguish two stages in a system's post-disruption response, the absorptive dimension and the recovery dimension. The absorptive dimension is related to a system's robustness and capacity to mitigate initial loss posterior to a disruption. Meanwhile, the recovery dimension is the system's rapidity to return and reach an acceptable level of functionality after the disruption occurrence.

A social-physical (SP) system's post-disruption response is related to its resilience capacity so building …

Aldosterone Treatment Protects Connexin 30 And 43 Expression For Age-Related Hearing Loss, Jennifer A. Pineros Valencia

USF Tampa Graduate Theses and Dissertations

Age-related hearing loss (ARHL), also known as presbycusis, is the number one communication disorder affecting our aged population. Connexin proteins are essential for intercellular communication throughout the human body. Mutations in connexin genes have been linked to human syndromic and nonsyndromic deafness; thus, we hypothesize changes in connexin gene and protein expression with age may be involved in the development of ARHL. In our current study, connexin mRNA gene expression for CBA/CaJ mice at different age points were examined and correlations were analyzed between the changes in gene expression and functional hearing measures, such as ABRs and DPOAEs. Moreover, we …

Relationship Between Individual Characteristics And Received Social Support Among People With Serious Mental Illness, Samantha Dicorte

USF Tampa Graduate Theses and Dissertations

Past research on social support has mainly focused on perceived social support. Relatively less research has been done on received social support and how it can promote positive behavior outcomes. This study examines the importance of received social support, including background on social support, social support outcomes, and a theoretical foundation overview of the social stress model. In addition to a literature review, this study investigates the association between individual characteristics (i.e., diagnosis and substance abuse including alcohol, race/ethnicity, gender, age, and marital status) and different types of received social support (i.e., daily, mental health, and adherence support). Simple linear …

Reducing Screaming When Items/Toys Are Touched By Others, Talitha Vargas

USF Tampa Graduate Theses and Dissertations

Differential and positive reinforcement are non-intrusive interventions that have proven to be successful in decreasing problem behavior. This study aims to decrease the screaming behavior exhibited by a four-year-old male diagnosed with autism spectrum disorder (ASD) by using differential reinforcement without extinction alongside positive reinforcement in the form of edibles. The researcher hypothesized that the use of both interventions would be more effective than the use of one intervention. Using an AB experimental design, the intervention was successful in producing an 80% decrease from baseline screaming. Though successful, many limitations were presented throughout the study, affecting the consistency and replicability …
