Social Media And Perceptions Of Sexual Consent: Development And Psychometric Assessment Of Two Consent Measures, Kelley Rhoads

Graduate Theses and Dissertations

Background. Preliminary qualitative research suggests some college students believe sexual consent can be communicated and interpreted in Social settings, such as parties or bars, and in contexts lacking face-to-face interaction like text messages and Social media content. Previous sexual consent researchers have described perceptions of consent that occur in Social settings as “outside the bedroom” consent. The belief that sexual consent can be interpreted from Social media content or that accepting an alcoholic beverage from someone at a bar is indicative of sexual consent is problematic and warrants further study. Current validated consent scales are limited and do not assess …

Implications For The North American Lower Crustal 7.Xx Km/S Layer From An Exhumed Crustal Root, Western Canadian Shield, Calvin Everette Johnson

Graduate Theses and Dissertations

Studies of the Thorsby magnetic low, the southern extent of the 2,800 km-long Snowbird

Tectonic Zone (STZ) in Alberta, Canada, show pronounced lower crustal seismic reflectivity and preservation of a crustal root. These features may be correlative to the well-exposed central STZ, where two lower crustal tectonic events have been identified at 2.6-2.55 Ga and 1.92-1.89 Ga. High-resolution cross-sections of the central STZ reveal the late-stage interaction of Paleoproterozoic intracontinental thrust and strike-slip shear zones responsible for juxtaposing ca. >20,000 km2 of lower continental crust (0.9-1.5 GPa) with middle continental crust (0.5 GPa) (Mahan and Williams, 2005; Dumond et al., …

Investigation Of The Interaction Of Dimeric Ruthenium Complexes With Cytochrome B5, Christopher Dain Rupar

Graduate Theses and Dissertations

Photoreactive complexes to study the kinetics of electron transfer of proteins have been in use for a long time. It has always been speculated that complexes bind near the heme or the electron transfer reaction would not occur. But it is unkown exactly how the complex interacts with the protein. The structural, thermodynamic, and kinetic properties of rat liver microsomal cytochrome b5 were investigated when bound to ruthenium dimer complexes. Heteronuclear Single Quantum Coherence studies support a dynamic binding model of a dimer Ru complex bound near the protein’s heme involving residues H39, E44, G42, V61, G62, and H63. The …

Youth…Power…Egypt: The Development Of Youth As A Sociopolitical Concept And Force In Egypt, 1805-1923, Matthew Blair Parnell

Graduate Theses and Dissertations

This study focuses on youth as a symbol, metaphor, and subject involved in processes related to Egypt’s modernization, colonization, and liberation from the beginning of the nineteenth century through the 1919 Egyptian Revolution. It demonstrates that youth was not simply an unchanging stage of development between childhood and adulthood, but a construct reflecting the political, Social, and cultural interests of specific eras and perspectives. I critically analyze the local and global discourses on Egypt’s modernization, colonialism, and nationalist movement to understand how changing power relations within and outside the country affected conceptions of youth and youthfulness. Additionally, I suggest by …

The Cytotoxic And Antimicrobial Properties Of Pine Essential Oils: A Characterization And Comparison, Richard Sakul

Graduate Theses and Dissertations

In the forestry industry, the pine tree species are important because of their durable timber and fast growth. In Arkansas, trees such as the loblolly pine compose almost a third of the timberland, seven million acres. In addition to the lignocellulosic biomass, pine bark and needles potentially have industrial importance as a waste stream from which high value (e.g., pharmaceutical, cosmetics) chemicals could be extracted, which could potentially increase the profit margin of forestry operations. In this research, the possibility that pine needles harvested from industry processed pine tree residues could be used as an antibacterial or cytotoxic chemical agent …

Ciudad Letrada Y Poder En La Novela Del Caribe Hispánico Contemporáneo: La Noche Oscura Del Nino Avilés, Bachata Del Ángel Caído Y La Cazadora De Astros, Amilkar Ernesto Caballero

Graduate Theses and Dissertations

This dissertation analyzes Edgardo Rodríguez Julia’s La noche oscura del Niño Avilés, Pedro Antonio Valdez’s Bachata del ángel caído, and Zoé Valdes’s La cazadora de Astros from the perspective of the intersection between intellectuality and power. Its main thesis is that these three writers are “political” writers who postulate “possible worlds” to reconfigure the divisions of the Social world carried out by power vectors in their respective nations. These reconfigurations are based on “detour” strategies that attempt to deconstruct the canonical aesthetic forms and the discourses of truth established by those vectors. The first chapter analyzes the way the three …

Negotiating The Politics Of Representation In Iranian Women’S Cinema Before And After The Islamic Revolution, Alshaatha Sultan Al Sharji

Graduate Theses and Dissertations

From Mahvash, the Iranian entertainer who sang and danced coquettishly in numerous Iranian films that were produced before the Islamic revolution of 1979, to the skateboarding vampire girl who makes a feast out of abusive men in Ana Lily Amirpour’s A Girl Walks Home Alone at Night, the representation of Iranian women on screen has changed drastically. This comparative study focuses on the politics of representation of Iranian women in the cinema before and after the Islamic revolution, with the aim of deconstructing the readily-available notions of women’s oppression in Iran. It analyzes the works of female Iranian directors Forough …

Genetic Basis Of Biosynthesis And Cytotoxic Activity Of Medicago Truncatula Triterpene Saponins, Brynn Kathleen Lawrence

Graduate Theses and Dissertations

Saponins are a large family of specialized metabolites produced in many plants. They can have negative effects on a number of plant pests and are thought to play a role in plant defense. With current and possible future uses in industry and agriculture, saponins have also been shown to be hypocholesterolemic, hypoglycemic, immunostimulatory, antioxidative, anti-inflammatory, and cytotoxic. In spite of their usefulness, our understanding of the genetic basis for saponin biosynthesis is still incomplete. We generated recombinant populations with parents from genetically distinct accessions of Medicago truncatula, with either high or low accumulation and varying profiles of saponins. Primers for …

Preferred Leadership Communication Styles Across Cultures, Joy J. Cherfan

Graduate Theses and Dissertations

This thesis reports the results of a two-part study investigating preferred leadership communication styles across multiple cultural clusters. Utilizing a survey, part one identified the three most preferred leader communication styles (i.e., dominant, dramatic, contentious, attentive, animated, open, friendly, relaxed, impression leaving) in six cultural clusters. Using focus group data, the second part provides insight into subordinates’ perceptions of how these communication styles are enacted by leaders in each cluster. Guidelines on how to better communicate are offered to expatriates in hopes of helping them more successfully complete overseas tasks. Such guidelines are needed due to the high percentage of …

Characterization Of Histone Mutants Associated With Mitotic Defects In Saccharomyces Cerevisiae, Md Riajul Hossain

Graduate Theses and Dissertations

Nucleosomes, the basic unit and the building blocks of chromatin have an essential role in the tight packaging of DNA into higher order chromatin. Work from our lab and others have provided information on the contributions of different histone proteins and specific domains within the nucleosome made to create the centromeric chromatin structure required for normal chromosome segregation during mitosis. The DNA entry/exit site is a particular region of the nucleosome where histone H2A, H3 and H4 form critical interactions that appear to be essential for the association of Sgo1, a tension sensing protein that monitors kinetochore-microtubule attachment. In our …

Social Learning Remixed: Peer-Based Learning And Social Status In An Online Community Of Practice, Christopher Erin Mikkelson

Graduate Theses and Dissertations

People have engaged in peer-to-peer learning within communities of practice (CoPs) for centuries. Thanks to web 2.0 technology, people in the 21st century can now learn together and enact Social status even if they have never met face-to-face. Online communities of practice have since formed around a wide variety of activities, one of which is remixing. Remixing is defined as combining or editing existing materials to produce something new, but leaving each part recognizable as a separate entity. Remixing has recently been recognized as form of digital literacy because users must understand each component to make a good remix. Much …

Omni-Channel Supply Chain Management: Assessing The Impact Of Retail Service Operations In The Retail Supply Chain, Simone Theresa Peinkofer

Graduate Theses and Dissertations

The traditional retail environment, which is characterized by a clear division between brick-and-mortar and non-brick-and-mortar retail channels, has been recently disrupted by developments in e-commerce and mobile technologies. The result has been the emergence of omni-channel retailing. Within the reality of this new retail environment, it has been proposed that retailers should develop the necessary capabilities to fulfill consumer demand from anywhere – the store, the distribution center, or via drop-shipping from a supplier – which leads to the emergence of new operational complexities and challenges in the retail supply chain. In light of the growing popularity of these new …

Incorporating A New Class Of Uncertainty In Disaster Relief Logistics Planning, Emre Kirac

Graduate Theses and Dissertations

In recent years, there has been a growing interest among emergency managers in using Social data in disaster response planning. However, the trustworthiness and reliability of posted information are two of the most significant concerns, because much of the user-generated data is initially not verified. Therefore, a key tradeoff exists for emergency managers when considering whether to incorporate Social data in disaster planning efforts. By considering Social data, a larger number of needs can be identified in a shorter amount of time, potentially enabling a faster response and satisfying a class of demand that might not otherwise be discovered. However, …

Revision And Re-Writing As Adaptation: Using Adaptation Theory To Encourage Student Recognition Of Rhetorical Situations, Alicia Claire Troby

Graduate Theses and Dissertations

Many students don’t want to revise their writing, or do so in small, surface-level ways. This has been an issue many composition instructors have faced over the years, and there is a large body of scholarship about revision and the writing process by many in writing studies. From Nancy Sommers, Janet Emig, Donald Murray, and others, to more recent publications “post-process,” composition instructors and writing studies scholars are concerned about revision and the role it plays in students’ learning to write. As a strategy for teaching bigger-level revision, I implemented the use of adaptation theory (reading/watching and doing adaptation) as …

How Athlete Citizenship Behaviors Impact Fans' Perceptions Of Performance, Source Credibility, Image, And Fans' Future Behavior Intentions, Gregory Stine

Graduate Theses and Dissertations

The purpose of this study was to determine how knowledge of a professional athlete’s charitable involvement affects fans’ perceptions of the athlete’s performance, source credibility, and image, as well as fans’ future behavior intentions. Cultivation theory influenced the study, as it relates to how media portrayal of athletes affects fans’ perceptions. A perceived imbalance between (more) negative and (fewer) positive stories also influenced the study. The study is significant in that, given significant positive relationships between this knowledge of charitable involvement and these variables, athletes and teams could choose to promote players’ charitable initiatives more. This could potentially impact the …

Revisiting Social Isolation In America: An Egocentric Analysis Of "Feel Close To" Networks, Chao Liu

Graduate Theses and Dissertations

Evidences from interpersonal networks in which Americans discuss “important matters” (core discussion networks) suggest that Americans have become increasingly isolated. Using the national representative Science of Generosity Survey 2010, this paper revisits the issue of Social isolation. The survey asked respondents to name the people they felt close to in the last six months. On average, respondents mentioned 3.87 people they felt close to, a significant increase from the 1985 (2.94) and 2004 (2.08) core discussion networks. Education, income, and gender are significant explanatory variables for the “feel close to” networks. People with high education, those with high income, and …

The Effect Of Face-To-Face Versus Computer-Mediated Communication On Interpersonal Outcomes In Getting-Acquainted Situations, Nicole Rae Brandon

Graduate Theses and Dissertations

People use technology more today than ever before to self-disclose and form new relationships with others. Successful relationship development is often marked by the presence of positive interpersonal outcomes (i.e., closeness and liking). However, there is contention regarding whether computer-mediated communication (CMC) is as effective at developing positive interpersonal outcomes compared to face-to-face (FtF) communication. CMC is often considered subpar due to the lack of nonverbal cues that can be expressed. Two studies were designed to 1) compare the effect of FtF and CMC platform self-disclosures on closeness and liking in zero-acquaintance situations and 2) explore mediators that might explain …

"Everyone Has Thought About Killing Someone - One Way Or Another": Cannibalism And The Question Of Morality In Bryan Fuller's Hannibal, Kristi Michelle Pierse

Graduate Theses and Dissertations

Popular criticism insists that violence in the media perpetuates violence in the real world. This is an especially relevant argument today as we witness on a daily basis the violence that is occurring in the United States through mass shootings, police brutality, and countless other forms of aggressive actions. While studies do show a correlation between violent media and real-world violence, there is no absolute conclusion that proves such. My thesis addresses the moral lessons that can be learned through violence on television, particularly through the creative adaptation of Thomas Harris’ Hannibal Lecter series as reimagined by Bryan Fuller in …

Breast Is Best: A Case Study Of Bottom-Up Implementation, Britni Ayers

Graduate Theses and Dissertations

The institutional narrative surrounding breastfeeding is that breast is best. Research on infant feeding practices in the United States are abundant, especially among WIC recipients. Although WIC is championed as being a breastfeeding promotional venue, WIC recipients demonstrate lower breastfeeding rates than non-WIC recipients of similar economic standing suggesting the need for further research into the policies and breastfeeding promotional tools being implemented within WIC. Concurrently, research demonstrates that breastfeeding duration rates among WIC recipients can be prolonged with women’s interaction with a Breastfeeding Peer Counselors (BFPC). However, there has been little exploration into the experiences of BFPC or the …

Verbing History: A Textualist Approach To Gendered Politics In U.S. History Curriculum, Ginney Patricia Norton

Graduate Theses and Dissertations

Using three curricular interventions from World War II, I employ an alternative rhetorical history to understand how Social studies curriculum has become a space for the simultaneous deliberation of both national identity and gender politics. In working through the propaganda of Rosie the Riveter, the stories of the women of Oak Ridge, Tennessee, and the experiences of gay men and women in the military during the war, I suggest that Social studies curriculum normalizes and reifies gendered, racial, and queer citizenship in relationship to white, masculine, and heteronormative citizenship. It also utilizes epideictic rhetoric to rhetorically and historically construct problematic …

Leveling The Playing Field? A Content Analysis Of Espn.Com And Espnw.Com’S Online Coverage, Rachael Caldwell

Graduate Theses and Dissertations

The purpose of this exploratory study was to compare sports coverage provided by the male-centric website ESPN.com and its affiliated female-centric website ESPNW.com. The amount and type of coverage provided for female athletes was the primary focus of this study. Results suggest that ESPNW.com provides an outlet for increased coverage of women’s sports, but the type of coverage provided to female athletes is not equivalent to that of their male counterparts. These results supported findings in previous studies on mass media coverage of women’s sports, specifically coverage on the emerging field of Internet coverage.

Proposed Treatment Of Problematic Pornography Use: A Cognitive-Behavioral Approach, Jennifer Minarcik

Graduate Theses and Dissertations

As pornography use increases across the general population, mental health professionals are encountering more patients who present symptoms of sexual addictions and sexual compulsivity (Cooper et al., 2001). Never before have pornographic materials been so accessible to consumers. Viewing pornography is related to many negative consequences for the individual, including impairment of academic and professional functioning, subjective distress, and sexual compulsivity (Cooper et al., 1999a; Manning, 2006). Studies found pornography use by an individual typically leads to a decline in relationship and sexual satisfaction (Bridges, 2008a). Despite the growth in research related to problematic pornography use, to date there have …

Tableau Vivant [Living Picture], G J Christopher Drobnock

Graduate Theses and Dissertations

With an overwhelming concern for functionality, the design world and industrial production have moved far beyond the pure necessity of the handmade object. With the paper coffee cup, disposable utility is the primary goal; afterwards the service is performed and the thing is discarded. On the other hand, the clay object can be used and reused allowing a personal relationship to form between the user and the object, the maker and the user. My work is meant to reconnect us with the haptic; the tacit knowledge of the physical. I want the user to think of a place beyond the …

Fragmentality, Elena Volkova

Graduate Theses and Dissertations

Contemporary art is dedicated to the conversation between the past and the present, the established and the experimental; it becomes more and more trans-border, as life itself. Nowadays, people live in the world, where their beliefs, ideas, politics, and religion are constantly colliding. The more people expand boundaries and develop connections, the more complex and tangled our society becomes as a system.

FRAGmentality presents a set of mixed media pieces incorporating painting, weaving, embroidery and three-dimensional elements dedicated to these contradictions in the modern society. It deals with structures within Social relations and human nature.

Being a representative of a …
