Protective Factors Against Dating Violence Perpetration And Victimization, Meagan Kunitzer

Department of Sociology: Dissertations, Theses, and Student Research

Dating violence is a prominent problem among college students that can result in harmful physical and mental health outcomes. To date, much research has focused on risk factors, but less is known about protective factors that may decrease the likelihood of dating violence. As such, the current paper examines protective factors (e.g. religion, positive parental relationships) against perpetrating and/or experiencing dating violence and whether these protective factors operate similarly for both perpetration and victimization. Data were gathered in 2013-2014 at two large public universities using pencil and paper surveys (N = 1482). Bivariate results revealed that women have more protective …

Housework: Socialization Influences On Individual Performance, Couple Division Of Labor And Mental Health, Jaala Robinson

Department of Sociology: Dissertations, Theses, and Student Research

Despite the continued gender inequality in the division of housework, little research has considered how family housework socialization influences the amount of housework a person performs and their mental health. Socialization processes occur via the amount of housework performed in the home during childhood by each parent and the parents’ gender division of household labor. This analysis details three studies that explore the impact of socialization to housework. All three studies take advantage of intergenerational data from the Panel Study of Income Dynamics (PSID). The first study uses a social learning framework to test whether the amount of housework a …

Individual Differences In Social Responsiveness, Social Experiences, And Oxytocin System Genetic Variation In Depression Symptom Severity, Grace Sullivan

Department of Psychology: Dissertations, Theses, and Student Research

Social experiences including discrimination, low social support, and interpersonal conflict are reliable predictors of depression symptom severity (Costello, 1982; Monroe, Rohde, Seeley, & Lewinsohn, 1999; Phifer & Murrell, 1986). However, individual differences may buffer against or exacerbate risk (Pluess & Belsky, 2015). A more holistic and dimensional approach, in line with modern perspectives on mental health (Kircanski, LeMoult, Ordaz, & Gotlib, 2017), requires an investigation of individual differences that moderate associations of positive and negative social experiences with depression symptom severity. This dissertation assesses relative contributions of social experiences (low social support, discrimination, childhood trauma, and sexual objectification) to variation …

The Rise And Fall Of Wiñaymarka: Rethinking Cultural And Environmental Interactions In The Southern Basin Of Lake Titicaca, Maria C. Bruno, José M. Capriles, Christine A. Hastorf, Sherilyn C. Fritz, D. Marie Weide, Alejandra I. Domic, Paul A. Baker

Department of Earth and Atmospheric Sciences: Faculty Publications

Investigations of how past human societies managed during times of major climate change can inform our understanding of potential human responses to ongoing environmental change. In this study, we evaluate the impact of environmental variation on human communities over the last four millennia in the southern Lake Titicaca basin of the Andes, known as Lake Wiñaymarka. Refined paleoenvironmental reconstructions from new diatom-based reconstructions of lake level together with archaeological evidence of animal and plant resource use from sites on the Taraco Peninsula, Bolivia, reveal frequent climate and lake-level changes within major cultural phases. We posit that climate fluctuations alone do …

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 …

(Non)Religious Coping With A Natural Disaster In A Rural U.S. Community, Dena Abbott, Andrew Franks, Corey Cook, Caitlin Mercier

Department of Educational Psychology: Faculty Publications

Religious/spiritual (R/S) coping following natural disasters is associated with positive outcomes, leading to perceptions that the absence of R/S coping leads to negative outcomes among nonreligious individuals. However, little research explicitly explores the coping strategies of nonreligious individuals in response to natural disasters and traumatic events. The present study collected data from a sample of survivors of a natural disaster event (i.e., a tornado) to test the relationship between (non)religiosity/(non)spirituality, coping, psychological distress, and posttraumatic growth. Statistical models suggested that problem-focused coping facilitated posttraumatic growth and lower levels of psychological distress among people with lower levels of institutional religiousness and/or …

Mapping Collaborations And Partnerships In Sdg Research, Jane Payumo, Guangming He, Anusha Chintamani Manjunatha, Devin Higgins, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

Collaboration has become an essential paradigmin sustainable development research and in strategies for meeting the United Nations Sustainable Development Goals (SDGs). This study uses bibliometric methods and network analysis to examine research output and collaboration supporting the SDGs and explores means to detect and analyze research collaboration beyond the traditional definition of multiple, one-time co-authorship. We employed two additional lenses of collaboration: repeat collaboration and collaboration time point to quantify and visualize co-authorship data sourced from Microsoft Academic Graph. Our results show an increased collaboration rate over time at the author and institutional levels; however they also indicate that the …

Techniques And Forces And The Communicative Constitution Of Organization: A Deleuzian Approach To Organizational (In)Stability And Power, Jennifer J. Mease (Also Peeksmease)

Department of Communication Studies: Faculty Publications

This article introduces five principles of Deleuzian ontology and the conceptual framework of techniques and forces into emerging CCO scholarship addressing (dis)organization and power. By introducing Deleuzian concepts of (1) the virtual, (2) mutual (in)stability of meaning and materiality, (3) forces (and techniques), (4) communication, and (5) power, this essay builds a relational ontology that centers communication, speaks across existing theories of CCO, and offers a more detailed emphasis on power. In doing so, it enhances the explanatory power of CCO in general, as a set of theories useful for describing how organizational constitution and power play out in an …

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.

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 …

Agricultural And Food Security Impacts From The 2010 Russia Flash Drought, Eric D. Hunt, Francesco Femia, Caitlin Werrell, Jordan Christian, Jason A. Otkin, Jeff Basara, Martha Anderson, Tyler R. White, Christopher Hain, Robb Randall, Katie Mcgaughey

Department of Political Science: Faculty Publications

The flash drought and its associated heat wave that affected western Russia in the summer of 2010 had significant cascading agricultural and socioeconomic impacts. Drought indicators sensitive to soil moisture and evapotranspiration (ET) showed that the flash drought began in June 2010, then intensified rapidly and expanded to cover much of western Russia. By early July, almost all of the major wheat producing regions of Russia were experiencing extreme water stress to the winter and spring wheat crops. The timing of the onset of the flash drought was particularly devastating as the period of most rapid intensification overlapped with the …

Litigating Socio-Economic And Women’S Rights In Benin’S Constitutional Court, Alice J. Kang, Susanna D. Wing

Department of Political Science: Faculty Publications

Scholars debate the role of legal institutions in promoting human rights in Africa. Much of the discussion focuses on Anglophone countries and does not examine the gender of litigants. We propose a constitutionalism constrained perspective that argues that which and whose rights are adjudicated are shaped by the context of constitutional reform. Where reformists are primarily concerned with safeguarding civil and political rights, high courts may protect civil and political rights claims more often than socio-economic ones. Examining hundreds of human rights decisions issued by Benin’s Constitutional Court, we ask, which and whose rights does the court protect? We find …

Excluder: An R Package That Checks For Exclusion Criteria In Online Data, Jeffrey R. Stevens

Jeffrey Stevens Publications

Collecting survey data online can result in low-quality data. Survey participants may not complete the survey, may complete the survey too quickly or slowly, may not reside in the country they claim, or may use unacceptable screen types. Also, online surveys are plagued by automated bots attempting to complete the surveys while offering worthless data. Researchers collecting online data may want to check their data for these and other potential criteria to exclude problematic data entries. The excluder package uses three main function types to mark, check, and exclude data based on seven different exclusion criteria.

Improving Measurements Of Similarity Judgments With Machine-Learning Algorithms, Jeffrey R. Stevens, Alexis Polzkill Saltzman, Tanner Rasmussen, Leen-Kiat Soh

Jeffrey Stevens Publications

Intertemporal choices involve assessing options with different reward amounts available at different time delays. The similarity approach to intertemporal choice focuses on judging how similar amounts and delays are. Yet we do not fully understand the cognitive process of how these judgments are made. Here, we use machine-learning algorithms to predict similarity judgments to (1) investigate which algorithms best predict these judgments, (2) assess which predictors are most useful in predicting participants’ judgments, and (3) determine the minimum number of judgments required to accurately predict future judgments. We applied eight algorithms to similarity judgments for reward amount and time delay …

Exercise Shifts Hypothetical Food Choices Toward Greater Amounts And More Immediate Consumption, Karsten Koehler, Safiya E. Beckford, Elise Thayer, Alexandra R. Martin, Julie B. Boron, Jeffrey R. Stevens

Jeffrey Stevens Publications

Although exercise modulates appetite regulation and food intake, it remains poorly understood how exercise impacts decision-making about food. The purpose of the present study was to assess the impact of an acute exercise bout on hypothetical choices related to the amount and timing of food intake. Forty-one healthy participants (22.0 ± 2.6 years; 23.7 ± 2.5 kg/m 2 , 56% female) completed 45 min of aerobic exercise and a resting control condition in randomized order. Food amount preferences and intertemporal food preferences (preference for immediate vs. delayed consumption) were assessed using electronic questionnaires with visual food cues. Compared to rest, …

Lgbt Employment Nondiscrimination: Debating Sexuality And Citizenship, Kelsy Burke, Emily Kazyak, Alice Millermacphee

Department of Sociology: Faculty Publications

Introduction — Nebraska is 1 of 26 states that did not protect LGBT people from employment discrimination prior to Bostock vs. Clayton County. This article examines debates in Nebraska about LGBT employment nondiscrimination as a window into how citizenship is defined in relation to sexuality and gender identity.

Methods — We performed qualitative analyses on (1) the 2018 Nebraska Annual Social Indicators Survey of 902 respondents who shared their opinions on employment nondiscrimination legislation for LGBT individuals in close- and open-ended questions and (2) transcripts of the 2017 Nebraska state legislature debate of a bill that would have added …

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 …

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 …

“Pee In Peace” Or “Make Everyone Uncomfortable”: Public Perceptions Of Transgender Rights, Emily Kazyak, Kelsy Burke, Rosalind Kichler, Lora Mcgraw

Department of Sociology: Faculty Publications

We analyze a survey of Nebraskans as a case study to examine public opinion of transgender rights. Using a mixed methods design, we find an even divide among mostly cisgender survey respondents on whether transgender people should be able to use the restroom that aligns with their gender identity. Our findings mirror national data and show that identifying as female, being more liberal politically, and being less religious are associated with supporting this belief. Qualitative analysis of open-ended responses reveals that both supporters and opponents of transgender rights employ logics that implicate (1) the nature of transgender identities, (2) the …

Spatial Non‑Stationarity In Opioid Prescribing Rates: Evidence From Older Medicare Part D Beneficiaries, Seulki Kim, Carla Shoff, Tse-Chuan Yang

Department of Sociology: Faculty Publications

Previous research that examined spatial patterns of opioid prescribing rates and factors associated with them has mainly relied on a global modeling perspective, overlooking the potential spatial non-stationarity embedded in these associations. In this study, we investigate whether there are spatially non-stationary associations between opioid prescribing rates and key characteristics of older Medicare Part D beneficiaries and their prescribers using several data sources from the Centers for Medicare and Medicaid Services. All measures are aggregated to the ZIP code level, and a total sample size of 18,126 ZIP codes is included in the analyses. Our descriptive results from geographically weighted …

Molecular Identification Of Parasites In An Intestinal Coprolite From A Mummified Religious Dignitary Of The Piraino Mother Church Crypt, Sicily, Amanda Rollins, Krystiana Krupa, Georgia Millward, Dario Piombino-Mascali, Karl Reinhard, Frederika Kaestle

Karl Reinhard Publications

Intestinal contents were sampled from a spontaneously enhanced mummy from the Sepulcher of the Priests of the Piraino Mother Church in the Province of Messina, Sicily. This adult male mummy, Piraino 1, is an unidentified religious dignitary dating from the late-18th to mid-19th centuries. Immunological and molecular diagnostics were used to test for common and clinically significant parasites. A morphological diagnosis of Trichuris trichiura (whipworm) was confirmed genetically. A previously undetected Enterobius vermicularis (pinworm) infection was also identified genetically. These data indicate that the Piraino 1 individual was simultaneously infected with multiple intestinal parasite species indicative of poor hygiene. This …

Current Market Rates For Scholarly Publishing Services, Alexander Grossman, Björn Brembs

Copyright, Fair Use, Scholarly Communication, etc.

For decades, the supra-inflation increase of subscription prices for scholarly journals has concerned scholarly institutions. After years of fruitless efforts to solve this “serials crisis”, open access has been proposed as the latest potential solution. However, the prices for open access publishing are also high and are rising well beyond inflation. What has been missing from the public discussion so far is a quantitative approach to determine the actual costs of efficiently publishing a scholarly article using state-of-the-art technologies, such that informed decisions can be made as to appropriate price levels. Here we provide a granular, step-by-step calculation of the …

Censored Data Considerations And Analytical Approaches For Salivary Bioscience Data, Hedyeh Ahmadi, Douglas A. Granger, Katrina R. Hamilton, Clancy Blair, Jenna L. Riis

Department of Psychology: Faculty Publications

Left censoring in salivary bioscience data occurs when salivary analyte determinations fall below the lower limit of an assay’s measurement range. Conventional statistical approaches for addressing censored values (i.e., recoding as missing, substituting or extrapolating values) may introduce systematic bias. While specialized censored data statistical approaches (i.e., Maximum Likelihood Estimation, Regression on Ordered Statistics, Kaplan-Meier, and general Tobit regression) are available, these methods are rarely implemented in biobehavioral studies that examine salivary biomeasures, and their application to salivary data analysis may be hindered by their sensitivity to skewed data distributions, outliers, and sample size. This study compares descriptive statistics, correlation …

Probabilistic Mapping Of Human Functional Brain Networks Identifies Regions Of High Group Consensus, Ally Dworetsky, Benjamin A. Seitzman, Babatunde Adeyemo, Maital Neta, Rebecca S. Coalson, Steven E. Petersen, Caterina Gratton

Department of Psychology: Faculty Publications

Many recent developments surrounding the functional network organization of the human brain have focused on data that have been averaged across groups of individuals. While such group-level approaches have shed considerable light on the brain’s large-scale distributed systems, they conceal individual differences in network organization, which recent work has demonstrated to be common and widespread. This individual variability produces noise in group analyses, which may average together regions that are part of different functional systems across participants, limiting interpretability. However, cost and feasibility constraints may limit the possibility for individual-level mapping within studies. Here our goal was to leverage information …

Spring Break Or Heart Break? Extending Valence Bias To Emotional Words, Nicholas R. Harp, Catherine C. Brown, Maital Neta

Department of Psychology: Faculty Publications

Ambiguous stimuli are useful for assessing emotional bias. For example, surprised faces could convey a positive or negative meaning, and the degree to which an individual interprets these expressions as positive or negative represents their “valence bias.” Currently, the most well- wellvalidated ambiguous stimuli for assessing valence bias include nonverbal signals (faces and scenes), overlooking an inherent ambiguity in verbal signals. This study identified 32 words with dual-valence ambiguity (i.e., relatively high intersubject variability in valence ratings and relatively slow response times) and length-matched clearly valenced words (16 positive, 16 negative). Preregistered analyses demonstrated that the words-based valence bias correlated …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …

Factors Associated With Smoking In Low-Income Persons With And Without Chronic Illness, Monique T. Cano, David L. Pennington, Sara Reyes, Blanca S. Pineda, Jazmin Llamas, Vyjeyanthi S. Periyakoil, Ricardo F. Muñoz

Department of Psychology: Faculty Publications

INTRODUCTION Tobacco disparities persist among low-income smokers who seek care from safety-net clinics. Many of these patients suffer from chronic illnesses (CILs) that are associated with and exacerbated by smoking. The objective of the current study was to examine the differences between safety-net patients with and without CILs in terms of nicotine dependence and related factors (such as depression, anxiety) and self-efficacy regarding ability to abstain from smoking. METHODS Sixty-four low-income smokers who thought about or intended to quit smoking were recruited from the San Francisco Health Network (SFHN) and assessed for CILs, nicotine dependence, depression, anxiety, and smoking abstinence …

Reappraisal—But Not Suppression—Tendencies Determine Negativity Bias After Laboratory And Real‑World Stress Exposure, Candace M. Raio, Nicholas R. Harp, Catherine C. Brown, Maital Neta

Department of Psychology: Faculty Publications

Higher reactivity to stress exposure is associated with an increased tendency to appraise ambiguous stimuli as negative. However, it remains unknown whether tendencies to use emotion regulation strategies—such as cognitive reappraisal, which involves altering the meaning or relevance of affective stimuli—can shape individual differences regarding how stress affects perceptions of ambiguity. Here, we examined whether increased reappraisal use is one factor that can determine whether stress exposure induces increased negativity bias. In Study 1, healthy participants (n = 43) rated the valence of emotionally ambiguous (surprised) faces before and after an acute stress or control manipulation and reported reappraisal …

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, …

A New Tool For Equating Lexical Stimuli Across Experimental Conditions, Evan N. Lintz, Phui Cheng Lim, Matthew R. Johnson

Department of Psychology: Faculty Publications

In cognitive psychology and psycholinguistics, lexical characteristics can drive large effects, which can create confounds when word stimuli are intended to be unrelated to the effect of interest. Thus, it is critical to control for these potential confounds. As an alternative to randomly assigning word bank items to stimulus lists, we present LIBRA (Lexical Item Balancing & Resampling Algorithm), a MATLAB-based toolbox for quickly generating stimulus lists of user-determined length and number that can be closely equated on any number of lexical properties. The toolbox comprises two scripts: a genetic algorithm that performs the inter-list balancing, and a tool for …
