Estranged Temporality: How Time Tells Stories In Science Fiction, Phillip H. Howells

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

According to Darko Suvin in his influential critical treatise, Metamorphoses of Science Fiction, estrangement in Science Fiction (SF) gives authors the ability to build worlds related to but distant from our own using specific metaphors. This dissertation takes up this term and applies it to the fulcrum of time in SF as a method of creating possible futures and imaginative pasts in order to illuminate the realities of the present. The realities of the present are congruent with the material circumstances of the past, and this can be seen in the kinds of SF worlds built by members of …

Influence Of The Work Environment On Workplace Learning Of Undergraduate Engineering Interns, Yashin Brijmohan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Internships are an impactful form of workplace learning that helps undergraduate engineering students acquire and enhance competencies to improve their employability. However, the nuances about what makes an internship successful are not well understood. Furthermore, learning during engineering internships has not been thoroughly researched. Previous literature has mostly focused on internship outcomes, and there is little discussion on how to improve internship experiences to achieve the expected outcomes. Thus, this qualitative study explored the workplace learning environment of internships and how engineering undergraduate students engaged with workplace learning. The study has produced a comprehensive framework that illustrates important factors in …

Risk Factors For Online And In-Person Stalking, Intrusive Harassment, And Violence Within A Community Sample, Elisha J. C. Chan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Stalking and intrusive harassment (SIH) and stalking violence are prevalent and serious public health concerns associated with significant physical, psychological, financial, and social consequences. The growing proliferation of technology and the internet has only exacerbated the problem as SIH behaviors can be easily perpetrated via electronic means. Given its prevalence and negative impact, it is imperative to investigate the risk factors for online and in-person SIH and stalking violence to better predict and mitigate its detrimental effects. The current study therefore aimed to 1) examine the descriptive characteristics associated with online and in-person SIH and stalking violence; and 2) identify …

No significant difference in the average heart rate of a cow (P > 0.05) was observed between the 30 min control and virtual fenced periods for both trial dates. Second, I examined the influence of topography on wildlife species richness and presence at GSL using wildlife camera …

My Ai Companion: An Examination Of The Removal Of Erotic Role Play From Replika Through User Discussion On Reddit, Chelsee M. Allen

Department of Sociology: Dissertations, Theses, and Student Research

The development of artificial intelligence (AI) software has expanded rapidly in recent years, and thus has emerged the importance of exploring human relationships with AI chatbots. Replika, an app which uses AI to mimic human conversation, removed a function called Erotic Role Play (ERP) that allowed for sexual conversation with users’ customizable chatbots in February of 2023. This exploratory qualitative study examines the aftermath of ERP’s removal through an analysis of user interactions on Reddit. Five overarching themes emerged through the analysis of top posts to a Replika-specific subreddit, encompassing topics around mental health, stigma, coping, sex work and gendered …

Exploring Gen Z’S Identity Formation And Its Influence On Consumption Of Pop Culture And Entertainment Merchandise, Melisa Annette Spilinek

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Fandoms have grown in size and influence, becoming a complex and dynamic cultural phenomenon that richly impacts the consumption of media and consumer behavior. The capitalistic United States with its diverse and media-savvy population, is a prime destination to study fan studies, particularly among young adults who are a crucial component of fandom influence.

Online communities provide avenues for Generation Z to connect with others who share similar struggles, challenges, and interests, highlighting the importance of digital platofrms on the evolution …

French Interwar Popular Romance And Ideals Of Femininity: A Literary And Historical Study Of Magali, Kelly Kamrath

Department of Modern Languages and Literatures: Dissertations, Theses, and Student Research

Against a background of political turmoil, economic crises, and cultural upsets from both within and abroad, France between the two World Wars was home to a flourishing romance novel industry. At first glance lighthearted love stories seem simple and frivolous in comparison to the canonical writings of the time, such as those of Simone de Beauvoir and Jean-Paul Sartre. However, this literature was far from art for art’s sake. The romance novels of interwar France, written half a century before the scholarship of romance fiction would truly begin, have yet to receive the attention they deserve. During the interwar period, …

Exploring The Associations Of Afterschool Science Participation And Friendships With Science Identities, Patricia Wonch Hill, Grace M. Kelly, Julia Mcquillan, Jorge Ledesma, Miranda Melson, G. Robin Gauthier

Worlds of Connections Resources

Building on previous research that demonstrates the association of youth experiences in afterschool science and higher science identities, this paper presents a network study of 421 middle school students that examines afterschool science participation, friendship ties, and science identities. Participation in afterschool science clubs is associated with higher science identity, but the mechanisms and order of causality are unclear. Youth form friendships inside and outside of school, and peers may influence participation in afterschool activities, as empirical research on friendships shows that they are associated with youth interests. These peer interactions also have the potential to shape identity development during …

Tsunami Exposure And Mental Health Consequences: Protective Role Of Cultural Coping Strategies, Thulitha Wickrama, Michael J. Merten, K. A.S. Wickrama, Amanda Terrell

Department of Child, Youth, and Family Studies: Faculty Publications

There is a knowledge gap regarding the link between disaster exposure and adolescent mental health problems in developing countries. This study examines the case of Sri Lanka to investigate (a) the immediate and long-term mental health impact of the 2004 tsunami disaster on adolescents and (b) the potential moderating effects of unique cultural and family practices that prevail in Sri Lanka.

Less Activity Means Improved Welfare? How Pair Housing Influences Pinyon Jay (Gymnorhinus Cyanocephalus) Behaviour, London M. Wolff, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their environment and indicate welfare concerns. Changes in the housing environment in particular may have critical influences on behaviour and welfare. Here, we measured behavioural changes in a captive pinyon jay (Gymnorhinus cyanocephalus) population (n = 10) associated with a shift from single to pair housing. Using automated video processing, we show that pair housing greatly reduced overall activity levels in these birds. The …

Neuropsychological Intra-Individual Variability In Traumatic Brain Injury: Clinical Utility, Classification, And Associations With Outcomes, Jeremy A. Feiger

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Traumatic brain injury (TBI) survivors experience a range of sequelae including neurobiological brain changes, cognitive impairment, psychological difficulties, and functional changes. Neuropsychological assessment after injury is used to characterize current strengths and weaknesses to inform prognosis and interventions. There is currently no reliable and consistent method of assessing and classifying injuries in the post-acute and chronic phases of moderate to severe TBI (msTBI) that is associated with long term psychosocial outcomes. This study aimed to combine the use of within-person variability on neuropsychological test batteries and in cognitive response latency, known as intra-individual variability (IIV), with a novel cognitive phenotyping …

A Mixed Method Examination Of Bipositivity As A Factor Protecting Cis, Trans, And Gender Expansive Plurisexual Women Against Harmful Sexual Violence Outcomes, Allison E. Cipriano

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Plurisexual women are more likely to experience sexual violence, post-traumatic stress (PTS), and alcohol use problems compared to women with single gender attraction. Disproportionately high rates of sexual violence may partially explain the prevalence of PTS and alcohol problems experienced by plurisexual women. Yet, research on sexual violence, PTS, and alcohol use problems have rarely specifically investigated these phenomena among plurisexual women. Researchers have identified a positive association between binegative experiences and risk of sexual violence among plurisexual women, suggesting that sexuality-based experiences may be connected to sexual violence victimization for this population. While identifying factors predicting risk of sexual …

The Mental Health Experience Of Transgender And Gender Diverse Colombians: Que La Diversidad No Cueste La Vida, María Natalia Acosta Canchila

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Experiences of TGD people in various countries reflect difficulties accessing mental health services and significant mental health needs. In Colombia, experiences in broader healthcare systems suggest various barriers to care that include experiences of discrimination. However, specific experiences in mental health services have not been thoroughly examined. The current study aimed to understand the experiences, perceptions, and needs of TGD people in Colombia in mental health systems. Qualitative data was collected via 40 semi-structured interviews with TGD people in Colombia, data was analyzed via reflexive thematic analysis. Findings suggests great mental health needs related to needing support in the process …

Harassment, Stalking, And Violence On Campus: An Examination Of Persistent Cases, Madeline M. Eyer

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Stalking, harassment, dating violence, physical assault, and sexual assault continue to occur at elevated frequencies on college campuses. Most subjects cease engagement in these behaviors within a short period; however, a subset of individuals will engage in these intrusive behaviors over an extended length of time. While persistence has been examined in the stalking literature, only one study has examined risk factors of persistence in a college sample, and no studies have examined persistence for adverse behaviors outside of stalking (i.e., harassment, dating violence, physical assault, and sexual assault). Given the risk for physical and psychological harm toward targets as …

Susaki

Department of Biochemistry: Faculty Publications

Despite widespread adoption of tissue clearing techniques in recent years, poor access to suitable light-sheet fluorescence microscopes remains a major obstacle for biomedical end-users. Here, we present descSPIM (desktopequipped SPIM for cleared specimens), a low-cost ($20,000–50,000), lowexpertise (one-day installation by a non-expert), yet practical do-it-yourself light-sheet microscope as a solution for this bottleneck. Even the most fundamental configuration of descSPIM enables multi-color imaging of whole mouse brains and a cancer cell line-derived xenograft tumor mass for the visualization of neurocircuitry, assessment of drug distribution, and pathological examination by false-colored hematoxylin and eosin staining in a threedimensional manner. Academically open-sourced (https://github.com/dbsbjuntendo/ …

Understanding The Experience Of Bullying Of Students With Disabilities: A Phenomenological Study, Miriam Patricia Brenda Crinion

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The purpose of the dissertation study was to increase understanding of the social experiences of students with disabilities. Students with disabilities are at increased risk of being involved in the bullying dynamic and experiencing greater social difficulties relative to their typically developing peers. Consequently, students with disabilities are more likely to report adverse mental health outcomes due to bullying involvement. The current literature suggests the effectiveness of traditional bullying intervention programming for students with disabilities is limited. Students with disabilities may also perceive traditional coping strategies to be inadequate and may have their own unique coping strategies to help them …

Early Intervention Within Orthodontics: The Sociological Aspects, Trenton Hammond

Honors Program: Senior Projects (Public)

Orthodontic treatment is one of the final phases of dental treatment. Its use is to provide aesthetics in some cases, yet the quality-of-life aspect that it can provide is greatly underestimated. Orthodontic care can provide proper function of teeth, improve facial structure, avoid tooth decay/loss, and improve gum health (AAO, 2024). Within this research the overarching goal is to understand the sociological aspects of families looking to start orthodontic care, what the reasons behind starting or not starting are, and providing information to the public about orthodontics that may be misunderstood or might push people away from searching for orthodontic …

Understanding Older People’S Voice Interactions With Smart Voice Assistants: A New Modified Rule-Based Natural Language Processing Model With Human Input, Zhengxu Yan, Victoria Dube, Judith Heselton, Kate Johnson, Changmin Yan, Valerie Jones, Julie Blaskewicz Boron, Marcia Shade

College of Journalism and Mass Communications: Faculty Publications

The COVID-19 pandemic has expedited the integration of Smart Voice Assistants (SVA) among older people. The qualitative data derived from user commands on SVA is pivotal for elucidating the engagement patterns of older individuals with such systems. However, the sheer volume of user-generated voice interaction data presents a formidable challenge for manual coding. Compounding this issue, age-related cognitive decline and alterations in speech patterns further complicate the interpretation of older users’ SVA voice interactions. Conventional dictionary-based textual analysis tools, which count word frequencies, are inadequate in capturing the evolving and communicative essence of these interactions that unfold over a series …

Health Prompts Affect Consideration Of Health But Not Intertemporal Preferences While Promoting Healthier Food Choices, Olivier Tuyizere, Christopher Gustafson, Devin J. Rose

Department of Agricultural Economics: Faculty Publications

Diet-related diseases impact populations across the globe. While intertemporal preferences—a fundamental preference for the distribution of benefits across time—have been used to explain low-quality food choices, the recent literature proposes another cause: inattention to the future implications (or opportunity costs) of the options faced. Food choices tend to become habitual to conserve cognitive resources, rather than carefully modeling future health impacts. Both low discount rates for future benefits and attention to future health impacts predict healthier decisions. While intertemporal preferences are stable, attention may provide an opportunity to intervene in the decision process to promote healthier decisions. In this study, …

Department of Psychology: Faculty Publications

Background Few measures have been validated to screen for eating disorders (ED) in youth with chronic pain. We conducted confirmatory (CFA) of two established factor structures of the Eating Attitudes Test-26 (EAT-26) in a sample of youth with chronic pain attending an intensive interdisciplinary pain treatment (IIPT) program and examined the validity of the best-fitting model in predicting ED diagnoses in this sample.

Methods Participants were 880 adolescents (M age = 16.1, SD = 2.1) consecutively admitted into an IIPT program who completed the EAT-26 upon admission. CFA was conducted and in the case of inadequate fit, EFA was …

Seeing Is Believing: Religious Views, Perceptions Of Pollution, And Environmental Attitudes, Katelynn (Sage) Shadoan

Department of Sociology: Dissertations, Theses, and Student Research

This study explores the intersection of religious beliefs, perceptions of pollution, and environmental attitudes among Americans. Drawing upon Lynn White's seminal argument regarding Christian theology and its implications for environmental stewardship, this research investigates the role of biblical literalism in shaping environmental attitudes, particularly among conservative Christians. Using nationally representative survey data and logistic regression models, the study examines how the perceptions of pollution moderate the effects of views of the Bible on environmental concern. The findings reveal that while perceived pollution exposure is strongly associated with environmental attitudes, it does not moderate the association between biblical literalism and environmental …
