A Routine Electroencephalography Monitoring System For Automated Sports-Related Concussion Detection, Amirsalar Mansouri, Patrick Ledwidge, Khalid Sayood, Dennis L. Molfese

Department of Electrical and Computer Engineering: Faculty Publications

Cases of concussions in the United States keep increasing and are now up to 2 million to 3 million incidents per year. Although concussions are recoverable and usually not life-threatening, the degree and rate of recovery may vary depending on age, severity of the injury, and past concussion history. A subsequent concussion before full recovery may lead to more-severe brain damage and poorer outcomes. Electroencephalography (EEG) recordings can identify brain dysfunctionality and abnormalities, such as after a concussion. Routine EEG monitoring can be a convenient method for reducing unreported injuries and preventing long-term damage, especially among groups with a greater …

Leveraging Collaboration And Peer Support To Initiate And Sustain A Faculty Development Program, Anneris Coria-Navia, Scott Moncrieff

To Improve the Academy: A Journal of Educational Development

In today’s impoverished higher education fiscal climate, especially considering the enormous financial implications to higher education of accommodating the changes required by the coronavirus pandemic, “nonessential” though highly important programs, such as centers for teaching and learning (CTLs), are very likely to be underfunded. In this study, we illustrate how underfunded programs can leverage peer collaboration and support to initiate productive, formal systems of assistance for faculty by describing a number of such programs developed by and/or coordinated by our CTL. Moreover, we propose that sustainable programs, especially at small liberal arts institutions, must include a strong component of peer …

Raw And Pure Education In The Society, Iwasan D. Kejawa

Department of Educational Administration: Dissertations, Theses, and Student Research

What does education mean to individuals in the world today? Education is a way one can attain or improve his or her ability to lead and survive in the society of ours. Without educational training of the mind, it may be impossible to realize the importance of adaptability of living in the environment. Without education, It may also be difficult to embellish the use of both the mental and physical attributes possessed by individual beings.

What really is education? Education is the training of the mind to perform desire functions or to perpetuate the modality of obtaining an end or …

Mental Health Incorporation In Nebraskan Recovery Plans Following The 2019 Midwestern Floods, Isabelle Murray

Department of Environmental Studies: Undergraduate Student Theses

In March 2019, Nebraska was hit with major floods that caused extensive damage throughout the state. Nebraskans spent the following months recovering from many aspects of the natural disaster. One aspect of emergency response and the act of recovery that is commonly overlooked is the mental health of individuals following the traumatic events. The purpose of this thesis is to evaluate the level of incorporation of mental health care and services in recovery plans following natural disasters. The qualitative analysis of recovery plans focused on Nebraska and the county-level response to the 2019 Midwestern floods. The objectives were to identify …

Designing A Mobile App And Online Directory To Increase The Visibility Of Environmental Organizations In A Community, Kayla Vondracek

Department of Environmental Studies: Undergraduate Student Theses

Concern for environmental degradation, natural resource depletion, and public health has long been a necessary part of a strongly developed and sophisticated society. Humans are primarily responsible for the depletion of the natural environment as it supplies the commodities required to ensure the long-term survival of civilizations. As cultures continue to evolve, so does the practice of land stewardship and protection of resources. With the necessary expansion of industry and housing needed to support a rising human population, the management of natural resources, pollution control, and the environment has become increasingly important to people worldwide. Bernstein and Szuster (2019) suggest …

Using The Theory Of Planned Behavior To Understand The Behavioral Use Of Single-Use Plastic Bags By Students At The University Of Nebraska–Lincoln, Josephine Stoessel

Department of Environmental Studies: Undergraduate Student Theses

Reduction in the use of single-use plastic bags is a necessary sustainability step as it will reduce pollution of air, soil, waterways, and ingestion by marine animals. The Theory of Planned Behavior is used in this study to determine which components are the influencing factors for why students at the University of Nebraska-Lincoln use single-use plastic bags. An understanding of these factors allows for suggestions and recommendations for actions that can be taken by the university to combat this environmental issue. EcoCoin is an incentive-based program created by Penn State, and is the focus of this study. The literature review …

Convolutional Neural Networks Can Decode Eye Movement Data: A Black Box Approach To Predicting Task From Eye Movements, Zachary J. Cole, Karl M. Kuntzelman, Michael D. Dodd, Matthew R. Johnson

Department of Psychology: Faculty Publications

Previous attempts to classify task from eye movement data have relied on model architectures designed to emulate theoretically defined cognitive processes and/or data that have been processed into aggregate (e.g., fixations, saccades) or statistical (e.g., fixation density) features. Black box convolutional neural networks (CNNs) are capable of identifying relevant features in raw and minimally processed data and images, but difficulty interpreting these model architectures has contributed to challenges in generalizing lab-trained CNNs to applied contexts. In the current study, a CNN classifier was used to classify task from two eye movement datasets (Exploratory and Confirmatory) in which participants searched, memorized, …

Social Connectedness And Negative Affect Uniquely Explain Individual Differences In Response To Emotional Ambiguity, Maital Neta, Rebecca L. Brock

Department of Psychology: Faculty Publications

Negativity bias is not only central to mood and anxiety disorders, but can powerfully impact our decision-making across domains (e.g., financial, medical, social). This project builds on previous work examining negativity bias using dual-valence ambiguity. Specifically, although some facial expressions have a relatively clear negative (angry) or positive valence (happy), surprised expressions are interpreted negatively by some and positively by others, providing insight into one’s valence bias. Here, we examine putative sources of variability that distinguish individuals with a more negative versus positive valence bias using structural equation modeling. Our model reveals that one’s propensity toward negativity (operationalized as temperamental …

Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice

Department of Psychology: Faculty Publications

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, …

Skills-Based Intervention To Enhance Collaborative Decision-Making: Systematic Adaptation And Open Trial Protocol For Veterans With Psychosis, Emily B.H> Treichler, Borsika A. Rabin, William D. Spaulding, Michael L. Thomas, Michelle P. Salyers, Eric L. Granholm, Amy N. Cohen, Gregory A. Light

Department of Psychology: Faculty Publications

Background: Collaborative decision-making is an innovative decision-making approach that assigns equal power and responsibility to patients and providers. Most veterans with serious mental illnesses like schizophrenia want a greater role in treatment decisions, but there are no interventions targeted for this population. A skills-based intervention is promising because it is well-aligned with the recovery model, uses similar mechanisms as other evidence-based interventions in this population, and generalizes across decisional contexts while empowering veterans to decide when to initiate collaborative decision-making. Collaborative Decision Skills Training (CDST) was developed in a civilian serious mental illness sample and may fill this gap …

Nontarget Emotional Stimuli Must Be Highly Conspicuous To Modulate The Attentional Blink, Lindsay A. Santacroce, Brandon J. Carlos, Nathan Petro, Benjamin J. Tamber-Rosenau

Department of Psychology: Faculty Publications

The attentional blink (AB) is often considered a top-down phenomenon because it is triggered by matching an initial target (T1) in a rapid serial visual presentation (RSVP) stream to a search template. However, the AB is modulated when targets are emotional, and is evoked when a task-irrelevant, emotional critical distractor (CDI) replaces T1. Neither manipulation fully captures the interplay between bottom-up and top-down attention in the AB: Valenced targets intrinsically conflate top-down and bottom-up attention. The CDI approach cannotmanipulate second target (T2) valence, which is critical because valenced T2s can “break through” the AB (in the target-manipulation approach). The present …

Social Integration And Domestic Violence Support In An Indigenous Community: Women’S Recommendations Of Formal Versus Informal Sources Of Support, G. Robin Gauthier, Sara C. Francisco, Bilal Khan, Kirk Dombrowski

Department of Sociology: Faculty Publications

Throughout North America, indigenous women experience higher rates of intimate partner violence and sexual violence than any other ethnic group, and so it is of particular importance to understand sources of support for Native American women. In this article, we use social network analysis to study the relationship between social integration and women’s access to domestic violence support by examining the recommendations they would give to another woman in need. We ask two main questions: First, are less integrated women more likely to make no recommendation at all when compared with more socially integrated women? Second, are less integrated women …

Practical Problems And Positive Experiences With Ecological Momentary Assessment: Reflections From People Who Use Drugs, Kelly Markowski, Jeffrey A. Smith, G. Robin Gauthier, Sela R. Harcey

Department of Sociology: Faculty Publications

Background: Ecological momentary assessment (EMA) is an increasingly popular and feasible form of data collection, but it can be intensive and intrusive. Especially for at-risk, vulnerable populations like people who use drugs (PWUD), poor experiences with EMA may exacerbate existing chronic struggles while decreasing response rates. However, little research queries participants’ experiences with EMA studies.

Objectives: We explore participants’ positive and negative experiences with EMA, identifying what they liked about the study, the problems they experienced, and suggested solutions to these problems.

Methods: Results come from semi-structured interviews from 26 PWUD (6 women; 20 men) in Nebraska …

Constructing Pornography Addiction’S Harms In Science, News Media, And Politics, Kelsy Burke, Alice Millermacphee

Department of Sociology: Faculty Publications

In order to describe pornography’s harms in the twenty-first century, an age of unprecedented access to Internet technology, some advocates—including activists, religious leaders, politicians, and scientists—use a medical/scientific framework to claim that pornography is biologically addictive. This article examines public discourse on “pornography addiction” to extend theories of sociology of science and sociology of sexualities about scientific knowledge and the biomedicalization of sex and sexuality. Using content analysis of over 600 documents, including scientific studies, newspaper articles, and state government resolutions, we show how references to pornography as addictive emerged in the twenty-first century and grew most substantially in the …

Litigating Child Sex Abuse In Domestic Relations Cases, Mike Mchenry

Court Review: Journal of the American Judges Association

IN RULING ON PARENTING TIME DISPUTES COURTS ARE SOMETIMES CALLED UPON TO MAKE FINDINGS REGARDING WHETHER A PARENT HAS ABUSED A CHILD, INCLUDING SEXUAL ABUSE.

Sometimes these abuse allegations are handled in criminal court, and if a conviction enters then the matter is considered resolved. However, if the accused parent is acquitted, or if the prosecuting authority feels the evidence is inadequate to justify a criminal prosecution, then the obligation to assess the allegation’s merits falls to the domestic relations court, where busy dockets and inexperienced practitioners can present a challenge for the judge.

The Effects Of Phosphocreatine Disodium Salts Plus Blueberry Extract Supplementation On Muscular Strength, Power, And Endurance, John Paul V. Anders, Tyler J. Neltner, Robert W. Smith, Joshua L. Keller, Terry J. Housh, F Joseph Daugherty, Michael S. Tempesta, Alekha K. Dash, Daniel J. Munt, Richard J. Schmidt, Glen O. Johnson

Department of Nutrition and Health Sciences: Faculty Publications

Background: Numerous studies have demonstrated the efficacy of creatine supplementation for improvements in exercise performance. Few studies, however, have examined the effects of phosphocreatine supplementation on exercise performance. Furthermore, while polyphenols have antioxidant and anti-inflammatory properties, little is known regarding the influence of polyphenol supplementation on muscular strength, power, and endurance. Thus, the purpose of the present study was to compare the effects of 28 days of supplementation with phosphocreatine disodium salts plus blueberry extract (PCDSB), creatine monohydrate (CM), and placebo on measures of muscular strength, power, and endurance.

Methods: Thirty-three men were randomly assigned to consume either PCDSB, CM, …

Test-Retest Reliability And Minimal Detectable Change Of The Computerized Dynamic Posturography Proprio For Adults With Chronic Traumatic Brain Injury, Guilherme Manna Cesar, Thad W. Buster, Judith M. Burnfield

Department of Mechanical and Materials Engineering: Faculty Publications

Purpose: Balance deficits after brain injury, including reactive recovery from unexpected perturbations, can persist well after rehabilitation is concluded. While traditional clinical assessments are practical, the anticipatory nature of the tasks may mask perceptible balance control. Computerized dynamic posturography can directly quantify capacity to respond to unexpected, external perturbations. This study examined the reliability of the computerized dynamic posturography assessment with the device PROPRIO® 4000 in adults with traumatic brain injury and created the minimal detectable change for its standardized test.

Methods: Ten adults (ages 21–55 years) with chronic (average 10 ± 6 years post-injury) severe (loss of consciousness 2–75 …

Making Nice Or Faking Nice? Exploring Supervisors’ Two-Faced Response To Their Past Abusive Behavior, Shawn T. Mcclean, Stephen H. Courtright, Junhyok Yim, Troy A. Smith

Department of Management: Faculty Publications

Although extant research has shown that abusive supervision is a destructive and immoral form of leader behavior, theory provides conflicting perspectives on how supervisors respond to their own abusive behavior. We therefore draw upon and integrate moral cleansing theory and impression management and construction theory to explore whether and when supervisors engage in genuine reparations or impression management following episodes of abusive behavior. Results taken from a 3-week, experience sampling study of supervisors suggest support for the impression management path; following episodes of abusive behavior, supervisors higher on symbolized moral identity become more concerned with their image, and thus engage …

Predicting College Students’ Future Intentions To Engage In Public-Sphere Water Conservation Behaviors, Austin Wise, Donald Johnson, George Wardlow, Kathi Jogan

Department of Earth and Atmospheric Sciences: Faculty Publications

The purpose of this study was to describe selected college students’ (N = 252) perceptions of and future intentions (FI) to engage in public-sphere water conservation behaviors, and to determine if FI could be predicted by a single or linear combination of student demographic characteristics and latent variables. A majority of respondents agreed a growing population will negatively affect water quantity (90.5%) and there is a need for water resource management (85.6%). A majority disagreed or strongly disagreed that they (53.4%), their family (57.1%), or their friends (67.5%) practiced water conservation, or that people in their hometowns were concerned about …

Identification Of Contributing Factors For Driver’S Perceptual Bias Of Aggressive Driving In China, Yongfeng Ma, Xin Gu, Ya'nan Yu, Aemal Khattak, Shuyan Chen, Kun Tang

Department of Civil and Environmental Engineering: Faculty Publications

Aggressive driving is common across the world. While most aggressive driving is conscious, some aggressive driving behavior may be unconscious on part of motor vehicle drivers. Perceptual bias of aggressive driving behavior is one of the main causes of traffic accidents. This paper focuses on identifying impact factors related to aggressive driving perceptual bias. Questionnaire data from 690 drivers, collected from a drivers’ retraining course administered by the Traffic Management Bureau in Nanjing, China, were used to collect drivers’ socioeconomic characteristics, personality traits, and external environment data. Actual penalty points were considered as an objective indicator and Gaussian mixture model …

Coping With Covid‑19: An Examination Of The Role Of (Non) Religiousness/(Non)Spirituality, Dena Abbott, Andrew S. Franks

Department of Educational Psychology: Faculty Publications

Psychological distress and coping strategies employed during collective trauma events may vary for theists and atheists, as well as others along the (non)religious spectrum. The present study explored these differences via data collected from a US-based sample during the COVID-19 pandemic. Statistical models suggested relationships between maladaptive coping and distress for all participants and potential differences in coping and, in turn, distress between participants high and low in institutional religiousness and individual spirituality. Additionally, all participants, though especially nonreligious participants, appeared less able to engage in adaptive emotion-focused coping strategies. Implications for future research are provided.

Providing Sexuality Training For Psychologists: The Role Of Predoctoral Internship Sites, Dena M. Abbott, Debra Mollen, Elyxcus J. Anaya, Theodore R. Burnes, Madeline M. Jones, Victoria A. Rukus

Department of Educational Psychology: Faculty Publications

Sexuality education positively impacts health service psychologists’ ability to address sexuality, a vital component of overall health and well-being. There is little information about the integration of sexuality into the applied, fieldwork components of psychologists’ training. We surveyed 139 representatives of APA-accredited doctoral internship programs to assess sexuality content during internship training. Participants completed a survey assessing content integration of 12 domains specific to human sexuality. The most endorsed training related to sexual orientation and gender identity, sexual behavior, sexual ethics, and sex therapy were infrequent in the internship training curriculum. Implications for research, practice, training, supervision, and advocacy are …

Psychotherapy With Nonreligious Clients: A Relational-Cultural Approach, Dena M. Abbott

Department of Educational Psychology: Faculty Publications

In extant literature related to the integration of religion/spirituality (R/S) in psychotherapy, nonreligious clients are often excluded or briefly mentioned. Further, few theoretical frameworks supporting recommendations for intervention with or for conceptualization of nonreligious clients’ unique experiences and presenting concerns are offered. The present article summarizes psychotherapy-relevant scholarship related to nonreligious people in the United States and offers recommendations for intervention using a Relational-Cultural Therapy approach. In addition to increasing awareness of systemic oppression, resilience, and potential clinical needs of nonreligious clients, the article proposes concrete strategies for addressing structural inequity that disadvantages nonreligious people through conceptualization of such experiences …

Temperamental Constellations And School Readiness: A Multivariate Approach, Andrew S. White, Kate M. Sirota, Scott R. Frohn, Sarah E. Swenson, Kathleen Moritz Rudasill

Department of Educational Psychology: Faculty Publications

This study uses canonical correlation analyses to explore the relationship between mul- tiple predictors of school readiness (i.e., academic readiness, social readiness, and teacher-child relationship) and multiple temperamental traits using data from the second wave (age 54 months, n = 1226) of the longitudinal Study of Early Child Care and Youth Development (SECCYD; NICHD ECCRN 1993). This longitudinal study collected data on a large cohort of children and their families from birth through age 15. For academic readiness, only one temperamental constellation emerged, representing the construct of effortful control (i.e., high attentional focusing, high inhibitory con- trol). For peer interactions, …

Risk Factors For Bullying Victimization In Children With Neurofibromatosis Type 1 (Nf1), Peter L. Stavinoha, Cody Solesbee, Susan M. Swearer Napolitano, Steven Svoboda, Laura J. Kless, Alice Ann Holland

Department of Educational Psychology: Faculty Publications

Neurofibromatosis type 1 (NF1) is an autosomal disorder associated with numerous physical stigmata. Children with NF1 are at known risk for attention-deficit/hyperactivity disorder (ADHD), academic struggles, and significant social difficulties and adverse social outcomes, including bullying victimization. The primary aim of this study was to identify risk factors associated with bullying victimization in children with NF1 to better inform clinicians regarding targets for prevention and clinical intervention. Children and a parent completed questionnaires assessing the bully victim status, and parents completed a measure of ADHD symptoms. Analyses were completed separately for parent-reported victimization of the child and the child’s self-report …

Quaring Sorority Life: Identity Negotiation Of Queer Women Of Color In Culturally-Based Sororities, Antonio Duran, Crystal E. Garcia

Department of Educational Administration: Faculty Publications

Using quare theory as a theoretical framework and critical narrative inquiry as a methodology, researchers centered the stories of 20 queer Women of Color affiliated with culturally based sororities. Participants spoke about how they perceived gendered and heterosexist norms in their sororities and how they negotiated their identities in these environments. Findings reveal that queer Women of Color made crucial decisions regarding their identity negotiation while in the process of joining their organizations. Moreover, some participants articulated how, once affiliated, they strategically minimized attention to their sexuality and gender, while others asserted these identities to disrupt hegemonic norms.
