From Feminist Activist To Abortion Barbie: A Rhetorical History Of Abortion Discourse From 2013-2016, Skye De Saint Felix

Graduate Theses and Dissertations

This thesis provides a rhetorical history of abortion discourse with an emphasis on the rhetorical moment from 2013-2016. To uncover the rhetorical strategies used to shape consensus on abortion, I highlight three major events—Senator Wendy Davis’s (D-Fort Worth) notorious 13-hour filibuster against Texas’s HB2, the conservative capture of Davis as Abortion Barbie, and the Supreme Court case, Whole Woman’s Health v. Hellerstedt (2016). Because of these key rhetorical moments, pro-choice and anti-choice publics cultivated a period of heightened tension that reinvigorated abortion debates. While pro-choice groups employed narrative to centralize women as rhetorical agents and open spaces to discuss abortion, …

Is It We Or They? The Effect Of Identity On Collaboration And Performance In Buyer-Supplier Relationships, Siqi Ma

Graduate Theses and Dissertations

In today’s scale-driven and technology-intensive global economy, collaboration becomes the supply chain’s core capability (Liker and Choi, 2004). A well-developed ability to create and sustain fruitful collaborations gives companies a significant competitive advantage (Kanter, 1994). Retailers are increasingly relying on their suppliers to reduce costs, improve quality, and develop new processes and products faster than their rivals’ vendors can. On the other hand, suppliers benefit from retailers that they are able to monitor store-level demand in real time in order to ensure the top-selling items are in-stock or the accuracy and timeliness of retailer’s demand forecast. Previous literature has shown …

Phylogenetic Diversity Of The Bacterial Communities In Craft Beer, Lindsey Rodhouse Aug 2017

Phylogenetic Diversity Of The Bacterial Communities In Craft Beer, Lindsey Rodhouse

Graduate Theses and Dissertations

The craft beer industry is increasing in popularity in the United States. The craft brewing process typically does not use a pasteurization step, therefore the boiling process is the primary critical control step. Any microorganisms introduced after boiling, or those that are not killed during boiling, are likely to participate in fermentation and persist in the final product. Previous culture-based studies have isolated bacteria and yeast from craft beers at specific time points, but little research has been done on the process as a whole. The objectives of this research are to (1) track bacteria development throughout the brewing process …

Products Of Circumstance: Eighteenth-Century Runaway Indentured Servant Advertisements In A Changing Atlantic World, Amanda Page Mcgee Aug 2017

Products Of Circumstance: Eighteenth-Century Runaway Indentured Servant Advertisements In A Changing Atlantic World, Amanda Page Mcgee

Graduate Theses and Dissertations

Although indentured servitude remained a viable source of labor in colonial America and eighteenth-century England, newspaper advertisements demonstrated the transformations of the perceptions associated with indentured servants in the midst of a changing Atlantic World. Not only were indentured servants perceived as a type of commodity in the rising consumerist culture of the eighteenth century; but, the perceptions of these individuals – reflected in runaway newspaper advertisements – changed depending upon the political, social, and economic circumstances in which they existed. The volatile nature of colonial life combined with the social, economic, and political implications of the changing Atlantic World, …

Modeling Ozark Caves With Structure-From-Motion Photogrammetry: An Assessment Of Stand-Alone Photogrammetry For 3-Dimensional Cave Survey, Joseph H. Jordan Aug 2017

Modeling Ozark Caves With Structure-From-Motion Photogrammetry: An Assessment Of Stand-Alone Photogrammetry For 3-Dimensional Cave Survey, Joseph H. Jordan

Graduate Theses and Dissertations

Nearly all aspects of karst science and management begin with a map. Yet despite this fact, cave survey is largely conducted in the same archaic way that is has been for years - with a compass, tape measure, and a sketchpad. Traditional cave survey can establish accurate survey lines quickly. However, passage walls, ledges, profiles, and cross-sections are time intensive and ultimately rely on the sketcher’s experience at interpretively hand drawing these features between survey stations.

This project endeavors to experiment with photogrammetry as a method of improving on traditional cave survey, while also avoiding some of the major pitfalls …

Operating System Identification By Ipv6 Communication Using Machine Learning Ensembles, Adrian Ordorica Aug 2017

Operating System Identification By Ipv6 Communication Using Machine Learning Ensembles, Adrian Ordorica

Graduate Theses and Dissertations

Operating system (OS) identification tools, sometimes called fingerprinting tools, are essential for the reconnaissance phase of penetration testing. While OS identification is traditionally performed by passive or active tools that use fingerprint databases, very little work has focused on using machine learning techniques. Moreover, significantly more work has focused on IPv4 than IPv6. We introduce a collaborative neural network ensemble that uses a unique voting system and a random forest ensemble to deliver accurate predictions. This approach uses IPv6 features as well as packet metadata features for OS identification. Our experiment shows that our approach is valid and we achieve …

Factors Contributing To The Success Of First-Generation College Students At A Research University, Mary Margaret Hui Aug 2017

Factors Contributing To The Success Of First-Generation College Students At A Research University, Mary Margaret Hui

Graduate Theses and Dissertations

First-generation college students are students whose parents do not have a college degree, and they face numerous barriers in college. Yet, several first-generation college students (FGCS) are successful and are on-track to graduate with a bachelor’s degree in four years. Their success is important because education is associated with increased income, quality of life, and social mobility, making educational attainment even more significant in Arkansas, which has both low educational attainment and high poverty. Little is known about what can be done to close the achievement gap. It is important to analyze what helped FGCS succeed so that higher education …


The Relationship Between Exposure To Specialized Staff In A Classroom Setting And Observable Behaviors Among Students With Special Needs, Rachel Marie Prisco Aug 2017

The Relationship Between Exposure To Specialized Staff In A Classroom Setting And Observable Behaviors Among Students With Special Needs, Rachel Marie Prisco

Graduate Theses and Dissertations

This study aims to identify differences in the later integration of children with mild to moderate special needs based on their exposure to specialized staff regardless of the type of preschool they attended. This is done by observing the behaviors exhibited by those students with special needs and the proportion of the student’s day in a traditional classroom. One of the most noted issues with students who have special needs is their lack of appropriate early intervention with specifically-trained staff. This may attribute to those students delay in social emotional skills, and cognitive skills. Transitions, specifically those from one classroom …


Uas As An Inventory Tool: A Photogrammetric Approach To Volume Estimation, Richard Kramer Rhodes Aug 2017

Uas As An Inventory Tool: A Photogrammetric Approach To Volume Estimation, Richard Kramer Rhodes

Graduate Theses and Dissertations

Unmanned aircraft systems (UAS), also referred to as unmanned aerial vehicles (UAV) or remotely piloted vehicles (RPV), are associated with unmanned aircraft either controlled by a pilot on the ground or pre-programmed with specific flight paths. Small UASs have seen a massive increase in public interest in recent years as hobbyist platforms; they are, however, a potentially powerful tool in remote sensing and geospatial applications. Due to the increased availability of low-cost UAS, this technology could soon revolutionize many industries, including those that require volumetric estimation. Traditionally volumetric inventories have been performed with tape measurements, and in some instances where …


Factors Used To Determine The Teaching Load For Chairs In Public Community Colleges, Mandel G. Samuels Aug 2017

Factors Used To Determine The Teaching Load For Chairs In Public Community Colleges, Mandel G. Samuels

Graduate Theses and Dissertations

As the complexities of the departmental chair continued to increase, so did the importance of having a process to use to fairly assign the teaching load for departmental chairs. In 1982 Carolyn Branch conducted a survey to identify the factors that were being used. She received input from the chief academic officers that a process, procedure or formula was needed (Branch, 1982). The factors identified in Branch’s research did not lead to the development of a process for chief academic officers to use.

There has been no published research on this topic since Branch’s research in 1982. Therefore, I decided …


The Impact Of Social Situations On College Students’ Perceptions Of Sexual Consent, Casey Jane Ward Aug 2017

The Impact Of Social Situations On College Students’ Perceptions Of Sexual Consent, Casey Jane Ward

Graduate Theses and Dissertations

The majority of research examining sexual consent among college students focuses on how young adults communicate sexual consent during interactions immediately preceding a sexual encounter. However, preliminary research suggests that college students perceive that individuals begin to communicate sexual consent within social settings (e.g., at a bar) and through nonsexual interactions (e.g., text messaging); this has been labeled “outside the bedroom” consent. In order to further explore “outside the bedroom” consent, college students (n= 789) were randomly assigned to read four of sixteen vignettes. Within each vignette, four variables were manipulated: gender of the initiator (male or female), the social …
