Sentiment Analysis In Peer Review, Zachariah J. Beasley

USF Tampa Graduate Theses and Dissertations

Sentiment analysis, a widely popular subfield of natural language processing, has recently been used in the classroom to predict student attrition or to determine the mood of students, teacher strengths and weaknesses, or student perception of internship experience. These are all helpful indicators for the enhancement of students' academic experience but none improve the information gathered from or the reliability of peer review. This is particularly important in large courses with complex assignments (e.g., essays, software projects, and presentations) where scalable grading is requisite. In this dissertation, we apply sentiment analysis not on an assignment itself, but on the meaningful …

Discovery And Characterization Of Small Molecule Inhibitors Of Bromodomains, Md Rezaul Karim

USF Tampa Graduate Theses and Dissertations

The epigenetic “reader” modules bromodomains (BRDs) exert their diverse cellular functions through the recognition of acetylated lysines on histones and other proteins. Small molecule inhibitors of bromodomains have emerged as a promising therapeutic strategy to treat atherosclerotic cardiovascular diseases and cancers. Therefore, a large number of small molecule bromodomain inhibitors have been developed in the last decade, some of which are currently being assessed in the clinic. However, the success of bromodomain inhibitors is currently limited to the bromodomain and extra-terminal domain (BET) subfamily.

To address these, bromodomains outside the BET subfamily (non-BETs) such as TAF1, BRD7/9, TRIM28, and BRD8 …

While several of the study’s hypotheses …

A Dangerous New Era: Analyzing The Impact Of Cyber Technology On International Conflict, Kenneth Brown

USF Tampa Graduate Theses and Dissertations

This paper examines the causal relationship between cyber technology’s deep global integration and changes in how states struggle for power in the international system. Specifically, it argues that cyber technology has changed international conflict by providing external actors the ability to penetrate states’ grand strategy decision-making and implementation processes to an unprecedented degree and scope. As a result, the meaning of power has changed from a material-centric metric to one that is more nuanced and difficult to measure.

To explore this hypothesis, the study follows a three-step process. First, it examines the history of cyber technology, how it has become …

Ghostly Entanglements: Exposing Temporal Matter(Ing)S In Social Studies Education With (Re)Photography, Bretton A. Varga

USF Tampa Graduate Theses and Dissertations

Visual resources offer a variety of pedagogical advantages. Regardless of content, images can be leveraged to build critically analytical skills and used to cultivate dialogic literacies (i.e., articulations of thinking) about the social world. Further, images can be used to introduce and grapple with complex/abstract ideas. Given the relationship that social studies has to temporality (i.e., subjective engagements with the past, present, and future), visual resources also present teacher(s) (educators) with the opportunity to explore (theoretical) concepts foregrounding manifold relationships making up the social world (i.e., a world consisting of complex entanglements between non/human entities).

The purpose of this research …

Anorexia Nervosa And Bulimia Nervosa As Expressions Of Shame In A Post-Feminist, Emily Kearns

USF Tampa Graduate Theses and Dissertations

Anorexia nervosa and Bulimia nervosa are heavily gendered conditions affecting women to a far greater degree than men in a post-millennium Western setting. The psychologistic and medicalized approaches to studying and treating these disorders do not account for socio-cultural and epistemic preferences. This paper draws a connection between shame (as emotion and affect) and these gendered disorders. Further, this work analyzes neo-liberalism, post-feminism, and consumerism as predatory elements of Western culture especially affecting women.

Editing The Self Away: The Effects Of Photo Manipulation On Perceptions Of The Self, Roxanne N. Felig

USF Tampa Graduate Theses and Dissertations

The use of editing applications to manipulate photos of one’s self prior to sharing them on social media has skyrocketed over the past decade, particularly among women. However, there is little research examining the consequences of such behavior. In this research, we experimentally examined the consequences of editing a photo of one’s self on self-objectification and self-concept clarity in a sample of 231 women. A correlational Pilot Study provided preliminary evidence for a relationship between self-objectification, self-concept clarity, and photo manipulation, and my Thesis was conducted to further explore this relationship. We anticipated that when women were exposed to objectifying …

Social Exclusion Of Older Mossi Women Accused Of Witchcraft In Burkina Faso, West Africa, Clarisse Barbier

USF Tampa Graduate Theses and Dissertations

Among the most marginalized populations in the world, one group of women has been persistently ignored, silenced, and forgotten. In Burkina Faso, West Africa, older women in rural villages are often the target of witchcraft accusations; the consequences of these accusations are alarming because these women undergo violent attacks, face exclusion from their villages, and become the most vulnerable and marginalized segment of the Burkinabe population. Between August 2017 and November 2018, I conducted an ethnographic study of Burkinabe women accused of witchcraft living in two shelters in the capital city of Ouagadougou and examined women’s experiences of accusation, trauma, …

Exploring The Relationship Between Pre-Medical Student Motivation And Academic Performance: Strategies To Improve Student Success, Lauren Albaum

USF Tampa Graduate Theses and Dissertations

Colleges and universities are under increasing pressure to meet post-baccalaureate graduate and professional school outcomes, with the majority of students indicating their central reason for attending college is to “landing a better job” (Eagan et al., 2016). Thus, even as interest in medical school and veterinary medical school continues to rise (Eagan et al., 2016), thereby increasing the competition to obtain an acceptance, students and parents continue to hold an expectation that their undergraduate institution will adequately prepare them to successfully matriculate into medical school or veterinary medical school. Although a variety of factors influence acceptance to professional school, earning …

How The Use Of Learner-Generated Images And Authentic Materials Affects The Comprehension And Production Of Vivid Phrasal Idioms In L2 English Learners, Melissa Larsen-Walker

USF Tampa Graduate Theses and Dissertations

Vivid Phrasal Idioms (VP Idioms) are non-compositional, figurative phrases that have limited flexibility, such as “once in a blue moon.” Research suggests that facility with idioms is an integral part of communicative competence in an L2 (Liontas, 2017; Sinclair, 1992). Despite the fact that they are ubiquitous throughout informal, spoken language (Karlsson, 2013; Liu, 2008), and occur less frequently in other registers of usage, newscasters and politicians employ VP Idioms for communication in what Myers (1996) has called the presentational mode. They also appeari in academic discourse (Liontas, 2008). Nevertheless, research suggests that the English language learners in formal educational …

From Colonial Legacy To Difficult Heritage: Responding To And Remembering An Gorta Mór, Ireland’S Great Hunger, Katherine Elizabeth Shakour

USF Tampa Graduate Theses and Dissertations

This research has two main components: first, an exploration of how communities react to socio-natural disasters through time, and second, a discussion of how communities constructed the responses to tragedies as heritage over the long term. Disasters are often conceived as short-term, natural catastrophes, but, in reality, they are always social and natural phenomena and often impact communities for years or even decades. Employing archaeological, historical and ethnographic methods, this project examines local, regional, and national responses to social upheaval cause by prolonged food insecurity beginning with a potato blight in 1845 in Ireland. The 1845-1850 Famine was not just …

Investigation Of Navigation Systems For Size, Cost, And Mass Constrained Satellites, Omar Awad

USF Tampa Graduate Theses and Dissertations

The feasibility of using radically inexpensive micro-electromechanical system (MEMS) technology for navigation of a nanosatellite is investigated with a focus on attitude estimation. Typically, larger satellites are equipped with star cameras, sun sensors, or Earth horizon sensors for attitude estimation. These sensors can provide very accurate attitude measurements. A nanosatellite is highly size, power, and cost constrained and cannot readily accommodate these sensors. Our mission is to design, build, and operate a radically inexpensive nanosatellite system. While there is no consensus on what constitutes a "radically inexpensive" satellite, our goal is a maximum cost of $10,000 per unit. This precludes …
