Essays On Networks And Gender Dynamics In Corporate Finance, Xiaonan Wei
Graduate Theses and Dissertations
In my dissertation, I explore the effect of networks and gender dynamics on corporate finance. In my first essay, I examine the effects of personal network on insider trading decisions. Using COVID-19 as a shock to test personal network effect, I find individuals were influenced by information about COVID-19 provided by the members of their personal networks. S&P 1500 insiders whose personal networks contained higher fractions of socially connected individuals from countries affected by early stages of COVID-19 were more likely to sell shares of their firms in the period preceding the U.S. stock market decline, and they are less …
The Impact Of Algorithmic Control And Algorithmic Management In Online Labor Platforms, Yaping Zhu
The Impact Of Algorithmic Control And Algorithmic Management In Online Labor Platforms, Yaping Zhu
Graduate Theses and Dissertations
Online labor platforms (OLPs) are transforming the way organizations operate and how people work. Platform work has been characterized as promoting autonomy and flexibility. Workers interact with a platform rather than human managers to accomplish tasks and they have the freedom to decide when, where, and how much to work. Yet, platform workers increasingly bemoan working conditions, revealing that the expected autonomy and flexibility benefits of platform work have not materialized. Current IS research sheds light on this phenomenon by explaining that platform organizations use algorithms to manage and control workers (i.e., algorithmic control). Yet, our understanding of how algorithmic …

News Media Coverage And Framing Of Human Trafficking In The United States, Chloe Junkerman
News Media Coverage And Framing Of Human Trafficking In The United States, Chloe Junkerman
Graduate Theses and Dissertations
This study examines what makes mainstream news media representations of human trafficking cases newsworthy, and how news media choose to frame sensationalized human trafficking stories. While there have been several notable studies examining news media framing of human trafficking as a social issue more generally, prior research has yet to empirically investigate how the news media cover specific human trafficking cases, thus overlooking what types of attributes make cases newsworthy. This is an important gap in research as the types of cases that get covered, or ignored, by news media, and how stories frame various aspects of these crimes, informs …
To Be Framed: Investigating The Influence Of American Media Frames On Gun Control, William C. Chamblee
To Be Framed: Investigating The Influence Of American Media Frames On Gun Control, William C. Chamblee
Graduate Theses and Dissertations
Gun control may be one of the most polarizing political issues facing America today. While there are many factors that contribute to gun control controversy, one may be how it is framed by news organizations. Research suggests that the emergence of partisan news media, differing levels of issue salience, and the public’s increased willingness to selectively expose could widen the gap between both Republicans and Democrats through their opinions on the issue of gun control, causing polarization. Using a survey, this study found that both Republicans and Democrats are likely to selectively expose to partisan media outlets and that a …

Diversity Equity And Inclusion Education: An Evaluation Of The Safe Zone Allies Program, Shannon E. Hart
Diversity Equity And Inclusion Education: An Evaluation Of The Safe Zone Allies Program, Shannon E. Hart
Graduate Theses and Dissertations
Diversity, Equity, and Inclusion gained unprecedented popularity from 2019 to 2022. The tide turned in 2023, and Anti-DEI legislation continues to gain momentum nationwide. This backlash may be warranted, as research demonstrates that DEI can backfire. DEI programs remain unregulated, understudied, and often paradoxically under-supported despite their potential to catalyze positive social change. Two studies were conducted to begin creating standardized, accessible, and evidence-based DEI best practices. Safe Zone Allies, a LGBTQIA+ specific DEI program was selected for program review because; (a) it was not developed hastily, (b) it was not siloed, and (c) the curriculum is evidence-based. The first …

Food Insecurity Among Women: The Data Gap And The Path Forward, Beth Dedman
Food Insecurity Among Women: The Data Gap And The Path Forward, Beth Dedman
Graduate Theses and Dissertations
Quantification frames the world in terms of hierarchies, reputation, and status, thereby making important indicators comparable, and subsequently stripping them of their context, history, and meaning. Numerical knowledge is essential, yet if it is not closely connected to more qualitative forms of knowledge, it leads to oversimplification, homogenization, and the neglect of the surrounding social structure. Feminist-based research is completely antithetical to this form of research, focusing on qualitative experiences, the effects of relationships of power, and adding the necessary context to the quantifiable information. As of yet, most research in the Northwest Arkansas region as it pertains to the …
Overpowered, Benjamin Pearey
Overpowered, Benjamin Pearey
Graduate Theses and Dissertations
Overpowered is a temporary installation of a tiled living room, modeled after my own living room in a rental apartment in Fayetteville, Arkansas. It takes its name from a kind of sci-fi electro-disco love song released in 2007 by Roísín Murphy, who breaks down romantic attraction into preprogrammed meanings, chemical needs and matching data - and her sense of losing control, succumbing to the overwhelming forces at play. My installation is borne from a similar feeling. It is a continuation of a navigation of daily life under the pressures of external forces exerted by the various systems that underpin society …
