A Multimodal Assessment Of Disgust In Response To Traumatic Event Reminders Among Adolescents, Teah-Marie R. Bynion

Graduate Theses and Dissertations

The majority of youth will report traumatic event exposure by the time they reach adulthood. Research suggests exposure to such events is linked to myriad negative outcomes. Not all traumatic events are alike, however; evidence suggests that, compared to non-interpersonal events, interpersonal events in which another person intentionally perpetrates harm are linked to elevations in the likelihood of negative outcomes, including posttraumatic stress disorder (PTSD). One reason for this discrepancy is that interpersonal traumatic events may elicit greater levels of disgust. However, this is a very under-developed research base, no study has examined this question among youth. The current study …

Characteristics Of High-Performing Women Resident Assistants At Private Liberal Arts Institutions, Grant C. Carlson

Graduate Theses and Dissertations

Resident Assistants (RA) are unique positions within a university. Undergraduate students are selected to enforce policy, complete administrative paperwork, and develop community in on-campus housing. Despite the critical role these students play in the advancement of university programs and retention, there is a gap in research regarding what contributes to the success of individuals in the position. Within the limited literature on RA performance and success, there is no current research relating to factors that are shared among the highest-performing women in the role.

The current study identified nine high-performing women RAs at three small liberal arts universities in the …

Paulo Coelho: Transnational Literature, Popular Culture, And Postmodernism, Anna Pavlova Murta

Graduate Theses and Dissertations

With over 350 million books sold worldwide in more than 80 languages, Paulo Coelho is an international literary phenomenon that moves “beyond culture of origin” (Damrosch 199) and inhabits the “world literary space” (Pascale 281). Would his novels, therefore, stand as materialization of Goethe’s humanist cosmopolitan vision upon the coinage of the term world literature? Many cultural scholars would argue to the contrary. This dissertation aims at exploring Coelho narratives and their popularity and controversial reception by contextualizing them within the contemporary scholarship on World Literature and within the global cultural economy.

An underlying assumption of this Cultural Studies approach …

The comparative subadult samples included the HK43 cemetery from Hierakonpolis (Egypt), the African American Cemetery from Cedar Grove (Arkansas), and the St. Martin’s Churchyard from …

Retaining Valued Human Capital: Investigating The Demand Side Of The Labor Market, Dorothea Roumpi

Graduate Theses and Dissertations

According to the Resource Based View, human capital resources are the key for sustainable competitive advantage. Human capital, however, is not an organizational possession and the voluntary turnover of valued human capital can erode an organization’s competitive advantage. In particular, subsequent losses in productivity and enabling rival firms to gain competitive advantage are only a few of the consequences of voluntary turnover.

The question of how organizations can influence turnover has triggered numerous conceptual and empirical papers. The majority of such endeavors focus on supply-side mobility constraints, exploring what organizations can do in order to minimize turnover intentions. On the …

The Influence Of Family Cohesion And Relationship Maintenance Strategies On Stress During Students’ Adjustment To College, Claire C. Strutzenberg

Graduate Theses and Dissertations

This study examined the effects of family cohesion and relationship maintenance behaviors on students’ experience of stress during the adjustment to college. One hundred and ninety-eight first-year college students completed measures assessing family cohesion; relationship maintenance behaviors expressed within their family systems; and academic, social, and personal-emotional stress. Results indicated that family cohesion is significantly and negatively related to students’ experiences of academic, social, and personal-emotional stress. Further, hierarchical regression and structural equation modeling provided insight to the additive influence of relationship maintenance behaviors on student stress. Analyses provided limited support for a mediation model, however, results demonstrated the importance …

Configuring Traditional Multi-Dock, Unit-Load Warehouses, Mahmut Tutam

Graduate Theses and Dissertations

The development of expected-distance formulas for multi-dock-door, unit-load warehouse configurations is the focus of the dissertation. From formulations derived, the width-to-depth ratios minimizing expected distances are obtained for rectangle-shaped, unit-load warehouse configurations. Partitioning the storage region in the warehouse into three classes, the performance of a multi-dock-door, unit-load warehouse is studied when storage regions can be either rectangle-shaped or contour-line-shaped. Our first contribution is the development of formulas for expected distance traveled in storing and retrieving unit loads in a rectangle-shaped warehouse having multiple dock doors along one warehouse wall and storage racks aligned perpendicular to that wall. Two formulations …

Mumbai Macbeth: Gender And Identity In Bollywood Adaptations, Rashmila Maiti

Graduate Theses and Dissertations

This project analyzes adaptation in the Hindi film industry and how the concepts of gender and identity have changed from the original text to the contemporary adaptation. The original texts include religious epics, Shakespeare’s plays, Bengali novels which were written pre-independence, and Hollywood films. This venture uses adaptation theory as well as postmodernist and postcolonial theories to examine how women and men are represented in the adaptations as well as how contemporary audience expectations help to create the identity of the characters in the films. Ultimately, this project hopes to fulfil the gap in scholarship on adaptations in Bollywood.

Social Interactions Occurring During An Introductory College Of Agriculture Course, Brittany Renea Leek

Graduate Theses and Dissertations

With the development of the internet, today’s students no longer are confined to the resources only found in their classrooms or public libraries and have been given the ability to gain access to virtually unlimited quantities of information on the topics or events they are discussing in their class rooms and with their peers. The use of technology for communication and education is rapidly changing, but the challenges of technology-driven learning opportunities rest on questions of access and use. There is a need to determine whether students use these methods (i.e., technology based) to more prevalently communicate today. The primary …

Long-Term Focus Of Attentional Biases, Garrett Pollert

Graduate Theses and Dissertations

Prior research regarding attentional biases, or patterns of visual attention, have focused on attention over the initial second when exposed to pictoral food stimuli. This manuscript reviews the literature regarding attentional biases in overweight/obese individuals over this timeframe for the two previously defined components of attentional bias (attentional orientation and attentional maintenance). A new component is proposed, called “attentional re-engagement,” defined as the pattern of attentional shifts towards target stimulus types over longer periods of time. Overweight/Obese and Normal-weighted participants were recruited and engaged in an Extended Dot Probe task, wherein attentional orientation, maintenance, and re-engagement were assessed using the …

Abandoning The Dream Of Omnipotence: On Autonomy And Self-Binding, Charlie Coil

Graduate Theses and Dissertations

I offer a prolegomenon to the philosophical study of a uniquely human activity—the self-binding act. This philosophical interest directly connects with the Enlightenment project of centralizing personal autonomy and individual freedom as primary values of personhood. Self-binding represents an easily referenced action that introduces a possible clash between autonomy and freedom on the one hand seen as in conflict with other ancient basic human values like self-control and avoiding akrasia. This dissertation investigates the inverted manner whereby an act of self-binding, which voluntarily and effectively limits a person’s options, can end up augmenting rather than interfering with personal autonomy. I …

This work is focused on applying network theory concepts in the field of literature to explore correlations between the mathematical properties of the social networks of plays and the plays’ dramatic genre, specifically how well social network metrics can identify genre without taking vocabulary into consideration. Almost no work has been done to study the ability of mathematical properties of network graphs to predict literary features. We generated character interaction networks of …

Effect Of Grain Sorghum Polyphenols On Fecal Fermentation, Danielle Marie Ashley

Graduate Theses and Dissertations

Obesity is an increasing epidemic which during 2015-2016 afflicted 39.8% of adults and 18.5% of youth in the United States. Not only can obesity affect quality of life, but it can lead to life-threatening diseases such as type 2 diabetes, heart disease, stroke, and some cancers. Animal and human research have demonstrated a pattern of gut microbiota perturbation in overweight and obesity, characterized by a reduction of beneficial bacterial species and increase in harmful species. Diet has been established as a contributing factor in gut ecology, and foods including fiber, resistant starch, and polyphenols have been found to both enhance …

Effects Of Serving Temperature On Sensory Perception And Acceptance Of Brewed Coffee, Matthew James Chapko

Graduate Theses and Dissertations

Coffee continues to be one of the most widely consumed beverages worldwide. How an individual perceives a cup of coffee is impacted by a plethora of factors including origin, growing climate, roasting level, and consumption habits. This thesis utilized both trained descriptive panelists and untrained consumer panelists to analyze how serving/consumption temperature modulates sensory perception of brewed coffee in regards to appearance, aroma, flavor, taste, and mouthfeel. Three varieties of coffee (Colombia, Ethiopia, and Kenya) were brewed and served to panelists at four temperatures: 70, 55, 40, and 25 °C. In one study (Study 1, Chapter 3), results from descriptive …

Modified Landscapes, Esther Nooner

Graduate Theses and Dissertations

Modified Landscapes is a body of work that reflects serious thought regarding Nature and its future. My personal experience and beliefs are at the core of why I believe this subject to be of great importance and why it will sustain many artists’ investigations for the time to come. The influences that informed this process are explored through experiences I had traveling, reading and exploring the photograph as a material object. The manipulation of the photograph is meant to question the beautiful, untouched scene and break the Romantic gaze that is historically tied to representations of Nature and insist upon …

Interpersonal And Ideological Kindness: A Biocultural Approach, Sally Averitt-Hubbard

Graduate Theses and Dissertations

In accordance with Richard Dawkins’ materialist “selfish gene” theory of human behavior, altruism is a subject matter that is treated conservatively by biologists, whose understanding of the human version of altruism tends toward mutualistic and sometimes reputation-based explanations of charity, kindness, and helping. Trivers (1971) first stated that non-kin altruism could evolve if altruistic behavior is balanced between partners over time, implicating a strictly mutualistic domain for kindness. But kindness herein is defined, beyond mere mutualism or reciprocity, as “the quality of being friendly, generous, and considerate.” Further, kindness tends to have an action-oriented dimension, as in Goetz et al.’s …

A Laboratory-Based Experimental Test Of Reasons For Living: Effects On Behavioral Approach Toward A Suicide-Related Stimulus, Sasha Micaella Rojas

Graduate Theses and Dissertations

There are few laboratory-based experiments that examine the effects of suicide-related risk or protective factors on suicide-related outcomes. Consistent with extant evidence-based theoretical models and treatments for suicidal behavior, it appears that increasing awareness of reasons for living may reduce risk for suicidal behavior. Thus, the current study represents an initial effort to experimentally examine the impact of bringing awareness to one’s most important reason for living on behavioral approach towards a suicide-related stimulus. Random assignment was used to assign an unselected undergraduate sample of 78 participants to complete either a script-driven imagery procedure specific to the most important reason …

Tapping The Voices Of Learners For Authentic Student Engagement, Bryan Bronn

Graduate Theses and Dissertations

The purpose of this study was to examine the problem of practice of the decline in student engagement from the perceptions of secondary school learners as they proceed throughout their educational experience. According to researchers, learners who are engaged—meaning those who are committed and connected in active relationships with teachers, other learners, the learning environment, learning interests and ideas, the curriculum, and learning goals, are more likely to enjoy and be in control of their own learning [student agency]. This study is significant because of its potential to provide new understandings of the problem of a decline in student engagement …
