The Effects Of Geography And Proximity On Board Of Directors: An Exponential Random Graphs Approach, Panagiotis Giannakis

Graduate Theses and Dissertations

This dissertation aims at exploring how physical proximity, among other geographical elements, affects the synthesis of boards of directors, the decisions executives make, and, in general, organizations. Drawing on the rich literature in economic geography, these studies focus on re-evaluating the effects of geography on board of directors in the contemporary context characterized by significant technological advancements which is expected to minimize the effects of distance.

The first paper evaluates the geographic proximity effects on the likelihood of board interlock ties creation, while controlling for endogenous network processes. Additionally, all proposed network specifications are simulated in order to assess the …

Extending The Boundaries Of Supply Chain Transparency: Supplier Monitoring Activity Disclosure, Consumer Evaluations, And Brand Equity, Yanji Duan

Graduate Theses and Dissertations

Socially responsible policy makers and consumers are pressuring firms to make their supply chains more transparent by disclosing information about their supplier monitoring activities (SMA). Yet, high monitoring costs and the complexity of supply chains pose challenges for firms to effectively monitor their extended supply chain, including both first-tier and lower-tier suppliers. In order to comprehensively evaluate the net benefit from SMA, it is therefore critical to consider potential effects on drivers of additional revenues that may accrue from the disclosure of SMA to consumers.

Prior research on SMA has examined the associated cost, risk, and supplier relational implications on …

Gender In Apocalyptic California: The Ecological Frontier, Marykate Eileen Messimer

Graduate Theses and Dissertations

Climate change is the consequence of ideologies that promote human reproduction and resource consumption by sacrificing human justice, nonhuman species, and the land. Both biology and queer ecologies resist this notion of human separation and supremacy by showing that no body is a singular, impermeable entity, that all beings are biologically and inexorably connected. My dissertation demonstrates that fiction writers use this knowledge to locate a utopian vision that can counteract the dystopian impotence of living within climate change. This argument is founded on novels written by women and set in California, a state that uniquely inhabits a utopian and …

Possible Schemes For A Single Photon Switch, Hemlin Swaran Rag

Graduate Theses and Dissertations

I consider the effectiveness of a single control photon to route a target photon using two processes: the first one uses the transient excitation of a two-level system and the second one which uses the permanent population transfer in a three-level Λ-system to route the target photon. In the absence of a single control photon and when the system has additional decay channels, I find ways to optimize the success probability of routing with an increasing number of photons in the control field.

Mothers Of Intention: Women In The Ku Klux Klan And Massive Resistance, 1954-1968, Michele R. Johnson

Graduate Theses and Dissertations

This dissertation examines women in the Massive Resistance movement and the Ku Klux Klan of the classic Civil Rights period, 1954-1968. Specifically, it illustrates the way in which these women used their assigned gender roles as women, and specifically as mothers, to further white supremacist goals. White women have been an integral part of white supremacy in the United States from the beginning, yet are rarely portrayed as such. White supremacist movements are most often viewed through a male lens and gender in white supremacy is most often focused on how white men perform gender within the movements. While that …

The Effects Of Hand Holding On Cancer Patients Level Of Anxiety: A Single-Case Study, West Loveland

Graduate Theses and Dissertations

The purpose of this dissertation was to explore how the anxiety levels of non-Hodgkin’s lymphoma patients receiving chemotherapy are affected while holding hands with a secure attachment. This study utilized three experimental single-case designs: participant one measured under a B-design, participant two measured under a B-A design, and participant three measured under an A-B design. Each participant’s anxiety was assessed during six chemotherapy treatments and one meeting with their primary oncologist to discuss the prognosis of their cancerous disease. Results visually indicate a greater effect on anxiety reduction during treatment when the intervention is utilized compared to only having a …

Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race

Graduate Theses and Dissertations

Confidence can be a strong predictor of accuracy if circumstances are ideal (Wixted & Wells, 2017), but ideal circumstances are not always present. As such it is important to understand ways to ameliorate potentially negative effects on eyewitness metacognition. Rapport building, though seen as an important element of police/witness interaction (Vallano et al., 2015), can lead to some potentially negative memory effects (Wright et al., 2015). Additionally steering, or the process of directing a witness toward a particular suspect, can increase false identifications. Recently the researcher has developed a paradigm meant to better calibrate confidence by reinstating the context of …

The Impact Of Mother And Adolescent Offspring Distress Reduction Training On Maternal Anxiety And Alcohol Related Behaviors Following Conflict, Sarah Ann Bilsky

Graduate Theses and Dissertations

Nearly half of people suffering from psychopathology meet criteria for more than one disorder. Scholars have focused on understanding factors that may simultaneously maintain multiple psychiatric problems. Elevated distress during interpersonal conflict is likely to maintain both alcohol use and anxiety psychopathology. Reducing distress elicited by normative mother-adolescent conflict holds particular promise. Conflict is common in families with problematic drinking and anxiety disorders and the affective impact of parent-offspring conflict is malleable. Distress reduction skills, such as cognitive reappraisal, are effective in reducing distress during conflict. The current study examined the unique and combined effects of training mothers and adolescents …

Collaborative Speculation And Overvaluation: Evidence From Social Media, Adam Barrett Booker

Graduate Theses and Dissertations

I use data from StockTwits and Twitter to provide evidence that investor attention on social media in the period before earnings is related to short-term overvaluation, consistent with bullish investors herding around common information. In the 2 to 60 days after earnings, returns for companies in the highest quintile of pre-earnings announcement investor attention are 4.2 percent lower than those of companies in the lowest quintile. I find evidence that the negative post-earnings drift result found in this study is related to investors waiting until after earnings are announced to enact costly arbitrage strategies. I further examine intra- and inter-network …

Fields And Consumer Groups: The Layered And Overlapping Roles Of Culture, Brandon James Mcalexander

Graduate Theses and Dissertations

The first essay investigates Bourdieu’s conceptualization of fields and its use in the marketing literature. It suggests that fields do not exist in isolation, but rather work together in a number of different possible configurations. Fields are reconceptualized as dominated, overlapped, unrelated, contrasted, and co-constituted, rather than completely distinct and opens a new theoretical space for interpretive researchers in marketing. The second essay is a descriptive ethnography of a local fab lab. The essay describes in rich detail the ways in which new skills are developed in a shared work environment, and contextualizes the findings using practice theory as a …

Polarization Properties Of Airy And Ince-Gaussian Laser Beams, Sean Michael Nomoto

Graduate Theses and Dissertations

The description of polarization states of laser light as linear, circular polarization within the paraxial scalar wave approximation is adequate for most applications. However, this description falls short when considering laser light as an electromagnetic wave satisfying Maxwell's equations. An electric field with a constant unit vector for direction of the field and a space dependent complex scalar amplitude in the paraxial wave approximation does not satisfy Maxwell equations which, in general, requires all three Cartesian components of electric and magnetic fields associated for a nonzero laser beam to be nonzero.

Physical observation of passing a linearly polarized laser through …

Choosing Information Systems As A Major: Factors That Influence Selection, Carole L. Shook

Graduate Theses and Dissertations

The purpose of this study was to examine student perceptions of factors affecting the decision to select information systems as an undergraduate major. Additionally, information systems students were compared to other business students to see if significant differences existed between groups. The four factors studied included: (a) personal interest in the major, (b) student competence, (c) value and utility, and (d) external influences of other people and academic experiences.

A convenience sample was used at a public university in the Southeastern region of the United States. Two hundred junior/senior students were selected as participants. One hundred of the students were …

Visualizing Ischemic Skin Flap Necrosis Through Phasor Analysis Of Autofluorescence Lifetime Images, Hallie Ramser Toomer

Graduate Theses and Dissertations

Necrotic skin flaps are difficult to predict and treat due to the lack of quantitative biomarkers. Label-free multiphoton microscopy is well suited for non-invasively monitoring skin metabolism through NAD(P)H and other intrinsic fluorophores, and offers immediate future directions for assessing necrosis in the clinic. The objective of this study was to assess whether phasor FLIM could be used to evaluate skin flap status and treatment efficacy in ex vivo skin sections. Phasor maps revealed differences in growth factor treatment and region, but changes in skin flap autofluorescence at 755nm excitation and 460nm emission were not just related to NAD(P)H. A …

Black Lives Matter: Understanding Social Media And The Changing Landscape Of Social Trust, Diana Carolina Cascante

Graduate Theses and Dissertations

This study aims to understand how social media is changing the landscape of social capital. Current research indicates a paradox between the growing use of mediated sources that are building social capital and low levels of social trust found in social media. People are skeptical of whether social media is trustworthy because there is no mechanism for fact-checking or verifying the information posted online. Since traces of social capital postulate social trust, it is needed to promote communal change. To understand this paradox, the Black Lives Matter movement is examined as an online platform that brings people together who have …

The Functional And Structural Analysis Of Drosophila Robo2 In Axon Guidance, Lafreda Janae Howard

Graduate Theses and Dissertations

In animals with complex nervous systems such as mammals and insects, signaling pathways are responsible for guiding axons to their appropriate synaptic targets. Importantly, when this process is not successful during the development of an organism, outcomes include catastrophes such as human neurological diseases and disorders. It is vital to determine the underlying causes of such diseases by understanding the development of the nervous system. There are many pathways that have been identified to play a role in this, however, we lack an understanding of how these pathways can promote such diverse outcomes in different populations of neurons. These pathways …

Effects Of Multivitamin-Mineral Supplementation On Mental Health Among Young Adults, Ya-Hsuan Chang

Graduate Theses and Dissertations

The percentage of young adults who had mental illnesses has increased from 2008 to 2015. However, few existing studies investigating the potential benefits of multivitamin-mineral (MVM) supplementation on mental health focused on young adults (18-24 years of age), whose eating behaviors are often unhealthy. The purpose of this study was to examine the effects of a MVM supplement on mental health in young adults. One hundred and thirty-three college students (Mage=20.59, SD=1.77; 80.15% female) participated in this randomized, double-blind, placebo-controlled trial. Participants consumed either a MVM supplement or a placebo for 30 days. The supplement contained B Vitamins, Vitamin C, …

Barriers Of African American Football Student-Athletes In Seeking Mental Health Services, Todd Andrew Wilkerson

Graduate Theses and Dissertations

Nearly half (48%) of collegiate football student-athletes are African American (NCAA, 2018). African American student-athletes face adversity at their respective institutions in the forms of racism and unfair treatment (Hill, Hall & Appleton, 2010). African American male student-athletes face educational stressors, campus stressors and athletic stressors. These stressors consist of academics, family, athletics and social relationships (Miller & Hoffman, 2009). Many African American student-athletes do not seek mental health treatment due to their status on campus (Watson, 2006). However, few studies have examined mental health and barriers for African American male student-athletes when seeking mental health services. As such, the …

"It Takes Less To Be A Man Nowadays": Exploring Persistence And Change In Masculinity Narratives Among College-Aged Men, Shelby Lynn Clark

Graduate Theses and Dissertations

Over the last several decades, a growing field of scholarship unpacks the concept of masculinity and its implications for gender and social hierarchy. Of particular interest are the ways in which hegemonic masculinity is perpetuated through the media and social discourse. The current study uses content analysis to highlight themes in the commodification of masculinity depicted in a series of Playboy Magazine’s “What Sort of Man Reads Playboy?” ads throughout the 1960s and 1970s. Conducting focus groups, I then use responses to these historical images and a contemporary equivalent to explore the persistence and evolution of portrayals of masculine ideals …

Characterization Of The Swine Gut Microbiome Dynamics, Culturomics And Probiotics, Xiaofan Wang

Graduate Theses and Dissertations

The gastrointestinal tract is a critical place where the immune system concentrates many of its protective functions. It exerts both physical and biochemical defenses against invading foodborne pathogens and other hazards. In pigs, the gut microbiota community assembled postnatal plays a very important role in the development of multiple physiologic aspects, such as development of the gastrointestinal tract, nutrient exchange, immune defense against foreign pathogens and growth performance. Microbiome-host communication changes with age. Despite recent advances in understanding the swine gut microbiome at different growth stages, a comprehensive longitudinal study of the lifelong dynamics of the swine gut microbiome is …

Consumer Preferences For Sustainable Rice Practices In Nigeria, Glory Esohe Okpiaifo

Graduate Theses and Dissertations

Improving the sustainability of rice production is important given its position as a global staple and its environmental footprint. The adoption of sustainable practices can generate positive externalities such as lower environmental pollution and improved working conditions for rice industry workers that could be capitalized via the design of consumer-based marketing strategies. The Sustainable Rice Platform (SRP) initiative aims at advancing the adoption of sustainable practices in rice production. We assess consumers’ perceptions of the SRP sustainability indicators using the Best-Worst Scaling approach to rank SRP sustainability attributes according to their preference shares and examine the effects of demographic characteristics …

Archive And Repertoire Of The Esala Perahera Performance In Sri Lanka, Hashintha Jayasinghe

Graduate Theses and Dissertations

This project examines the archive and the repertoire of the Esala Perahera in Sri Lanka and charts the ideological and cultural implications of the performance. The archival analysis begins with the interrogation of the historical chronicles and the recorded history of the performance in the Sinhala and English texts. Thereafter, travel literature and the dissemination of cultural knowledge on the Perahera are discussed. The study of the repertoire and the photographic archive explores key performances in the Esala Perahera in 2016 and 2017. Postcolonial theory, theories on cultural anthropology, and performance theory are used to analyze the archive and the …

New Sheriff In Town: Antecedents And Consequences Of Effective Lead Independent Directors, Dinesh Hasija

Graduate Theses and Dissertations

This paper examines a relatively new form of board leadership structure, the Lead Independent Director (LID), that has not received much attention in the corporate governance literature. This role was adopted in 2003 by most large US firms as a result of stock exchange mandates and pressure from institutional investors. From an agency theory perspective, this new form of leadership structure was designed to give additional control to independent directors, thus enhancing the monitoring function of the board. However, according to symbolic management theory, firms may adopt such a structure merely as a response to institutional pressures, thus making no …

Representations Of Domestic Workers In Modern Arabic Fiction, Samaher Aldhamen

Graduate Theses and Dissertations

In this study, I have examined the representations of domestic workers in a number of Arabic mid-century and contemporary novels, using feminism and intersectionality as my overarching framework. I employed several scholarships of feminism such as Marxist and postcolonial feminism to examine the discourse on working-class women. The initial assumption of this study is that there is a noticeable invisibility of domestic workers in Arabic novels. If these characters manage to find their way into a text, they are typically ahistorical figures whose subjectivity is not centered.

Among the Arabic novels I have examined, I found that the tradition of …

Poultry Labeling: Knowledge, Perceptions, And Preferences Among Adolescents, Eleni L. Parsons

Graduate Theses and Dissertations

The purpose of this study was to determine the knowledge, perceptions, and preferences of adolescents in regard to the labeling of poultry products. The theory of planned behavior (TPB) and Elaboration Likelihood Model (ELM) were used to display the relationship of perceptions, attitude, and behavior intentions. Quantitative data was collected in a descriptive research design. The population included youth, aged 14 – 18 years, involved in the Arkansas 4-H State O’Rama competition (N = 400). The sample (n = 80) ensured a 90% confidence interval of the population. Data was collected by administering paper surveys that addressed four product labels …

The Impact Of Bumpers College Of Agricultural, Food And Life Sciences International Programs On Student Motivation For Continuing College And Student Engagement In The Classroom, Olivia Caroline Caillouet

Graduate Theses and Dissertations

Colleges aim to increase student achievement, which has been linked to motivation and engagement, as well as increase global partnerships. There is also an increasing demand from students for international programs (IPs) that prepare them to be global citizens. This study aimed to compare student motivation for continuing college and student engagement in the classroom before and after an IP. Students who participated in a Bumpers College of Agricultural, Food, and Life Sciences IP between January 2018 and August 2018 were surveyed prior to, and two weeks and three months post-program participation (n = 24). The instrument had 51 Likert-scale …

On The Path To A Resilient Urban Food System In A Rural State: A Mixed-Method Needs Assessment Of Urban Producers And County Extension Agents In Arkansas, Catherine Elizabeth Dobbins

Graduate Theses and Dissertations

This project utilized a mixed-method needs assessment approach to urban agriculture in Arkansas, a predominately-rural state. Chapter II was a qualitative study, using semi-structured, in-depth interviews, that investigated the perceptions, needs, and experiences of Arkansas urban farmers and their interactions with the University of Arkansas Division of Agriculture Cooperative Extension Service (CES). Interviews were conducted with 16 urban farmers in Northwest and Central Arkansas. The interview data revealed individualized needs based on the size, years in operation, and mission of each urban farmer interviewed. General needs were determined, such as market pricing, co-ops, and access to appropriate equipment, but generally …

"I Like . . . Red Bone:" Colorism, Rappers, And Black College Sorority Women At A Predominantly White Institution, Whitney Frierson

Graduate Theses and Dissertations

In this thesis, I examine black college sorority women’s views about skin tone bias in hip-hop culture. I conduct interviews with 12 black undergraduate women in Black Greek Letter Sororities at a predominantly white institution. Prior research finds that rap music sends skin color messages to adolescent women through lyrical content and music videos. I build on this work by exploring how the experiences of being in college shape black college sorority women’s views on skin tone bias and hip-hop. I find that time in college has been an important life stage in which black sorority women gained an increased …

Emerging Adult Career Pathways: Understanding Aspirations And Switching, Tasmiah Amreen

Graduate Theses and Dissertations

Emerging adulthood is a stage of life characterized by a high degree of fluctuation in identity formation and future decision-making (Arnett 2015). During this life stage, emerging adults make decisions about their future career by assessing whether they want to continue with their current career pathway or whether they intend to switch. The present study investigates this process in terms of its overall prevalence – or how often emerging adults intend to switch career trajectories – and the correlates of it. Previous studies on career switching have focused largely on educational switches. This quantitative study operationalizes career pathway by using …

Applying Social Network Analysis To Identify How Chief Resilience Officers Promote Community Resilience Through Boundary Spanning, Interorganizational Collaboration, And Leadership, Kasey Couvillion Sisson

Graduate Theses and Dissertations

The purpose of this paper is to explore, in some depth, the functions of interorganizational collaboration (IOC) by analyzing the Chief Resilience Officer (CRO) role in 5 US cities. The CRO can act as a key network collaborator or boundary spanner – managing relationships, communication and strategic responses within and across organizations. This study researches the IOC and leadership functions of CROs operating in the social network of 100 Resilient Cities to better understand their boundary spanning roles. This study explores how CROs create and maintain IOC, characterizes their leadership functions and role, and examines the boundary spanning role as …

Remembering How To Listen: A Theoretical And Pedagogical Approach To Literacy, Adolescence, And Young Adult Literature, Stuart A. Morris

Graduate Theses and Dissertations

There is a substantial and growing body of critical theory on young adult literature (YAL), and there are a multitude of publications dealing with how secondary English/ELA teachers incorporate YAL in their classroom. From a curricular perspective, however, YAL is still most often considered inferior to canonical novels (i.e., “classics” or “great books”); thus, there has been no substantive or concerted movement to include YAL in secondary English/ELA at a curricular level, particularly in grades ten, eleven, and twelve. While the scholarship on YAL is extensive, discussion of YAL is most often devoted to pedagogy or literary theory, as if …
