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 …

Virtual Fencing In Livestock Management: Effects On Beef Cattle Stress And Enhancing Wildlife Conservation, Kaitlyn E. Dozler

School of Natural Resources: Dissertations, Theses, and Student Research

I examined the effects of virtual fencing on beef cattle stress and how implementing the technology can aid wildlife habitat conservation at the University of Nebraska Gudmundsen Sandhills laboratory (GSL) near Whitman, NE. First, I examined how virtual fencing influences acute heart rate changes in beef cattle fitted with the virtual fencing collars. 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 …

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 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–

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. This study used a random sample of 160 adolescents (ages 12–19) and their mothers who were exposed to the tsunami disaster while living in a southern Sri Lankan village and provided prospective data immediately after the disaster (2005) and …

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.

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 …

Mitigating Identity-Related Anxiety Through Humor And Immersive Storytelling With 360-Degree Video In Virtual Reality: A Study On Microaggressions’ Mental Health Effects, Changmin Yan, Alan Eno, Adam Wagler

College of Journalism and Mass Communications: Faculty Publications

Background: Microaggressions are subtle slights that can cause significant psychological distress among marginalized groups. Few studies have explored interventions that might mitigate these effects. Objective: This study aimed to investigate if and how humor-infused immersive storytelling via virtual reality (VR) could reduce identity-related psychological distress caused by microaggressions. Methods: Using a community-based participatory research approach, we developed a 7-min 360-degree VR film depicting scenarios of microaggressions across various identities. Fortysix college students participated in a controlled study where they were exposed to this immersive VR experience. We measured identity-related psychological anxiety, character identification, perceived humor, and perceived …

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 …

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.

Central to this effort is the discovery of nutrient profiles that can be targeted in nutritional interventions designed to promote brain health with respect to multimodal neuroimaging measures of brain structure, function, and metabolism. The present study therefore conducted one of the largest and most comprehensive nutrient biomarker studies examining multimodal neuroimaging measures of brain health within a sample of 100 older adults. To assess brain health, a comprehensive battery of well-established cognitive and brain imaging measures was administered, along with …

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 …

Eco-Anxiety Effects College Students, Alexa Edmundson

Department of Environmental Studies: Undergraduate Student Theses

A survey was conducted on the UNL student population to evaluate whether college students, 18-25 year olds who are currently attending an accredited post-secondary school, are experiencing eco-anxiety and if eco-anxiety affects their pro-environmental behaviors. Climate change is taking a toll not only physically on us but also mentally. The mental health of people, especially college students, is not often studied in relation to climate change, but if we are to understand how to create change in this issue then we need to be looking at the whole picture. The hypothesis is that if college students are experiencing eco-anxiety, then …

Charging Forward: A Comparative Analysis Of Facilitators To Electric Vehicle Adoption In Three U.S. States, Abigail Schroeder

Department of Environmental Studies: Undergraduate Student Theses

Electric vehicles (EVs) are a way to reduce greenhouse gas emissions from transportation, but low consumer adoption rates present a challenge. In order to understand what factors may facilitate EV adoption, a comparative analysis of three U.S. states was performed. These states have the highest rates of EV adoption in the country. Thus, studying them provided insights into what may make EV adoption successful. California, Hawaii, and Washington are the states with the highest EV adoption rates. Based on previous research, a list of 12 characteristics that may influence EV adoption was compiled and applied to each state, focusing on …

Educational Influences On Environmental Perception: A Semester Analysis Of The New Ecological Paradigm Scale In Undergraduates, Zoe Zingler

Department of Environmental Studies: Undergraduate Student Theses

This study evaluated the impact of a geography course, GEOG 181: Global Environmental Issues, at the University of Nebraska-Lincoln on students’ endorsement of the New Ecological Paradigm (NEP) using a pre-course and post-course NEP scale survey. Analyzing paired responses (n = 40) through t-tests and z-scores, only four of 15 statements had statistically significant shifts observed for the entire sample. However, a targeted analysis of students initially possessing lower endorsement of the NEP—early deniers—revealed significant paradigm shifts post-course. While women initially showed stronger NEP endorsement, men demonstrated notable changes following the course towards endorsement of the NEP. Academic majors, whether …

Paying To Reduce Disparity: Financially Incentivizing Workforce Diversity And Its Effects On Managers’ Promotion Decisions And Employees’ Effort, Bret S. Sheeley

College of Business: Dissertations, Theses, and Student Research

Disparities in employee representation persist in higher-level organizational positions despite recent attention to workforce diversity and its associated benefits. In response, companies have begun integrating diversity initiatives with varying degrees of specificity (hereafter, “initiative specificity”) into their managers’ compensation packages to increase underrepresented employees’ representation in higher-level organizational positions. This study uses an experiment to examine how offering managers financial incentives to accomplish diversity initiatives (hereafter, “diversity incentives”) and initiative specificity interact to influence managers’ promotion decisions and employees’ effort choices in a promotion setting.

The results suggest that as underrepresented employees’ pre-promotion efforts increase relative to overrepresented employees’ efforts, …
