Hyperarousal And Beyond: New Insights To The Pathophysiology Of Insomnia Disorder Through Functional Neuroimaging Studies, Daniel Kay, Daniel J. Buysse

Faculty Publications

Neuroimaging studies have produced seemingly contradictory findings in regards to the pathophysiology of insomnia. Although most study results are interpreted from the perspective of a “hyperarousal” model, the aggregate findings from neuroimaging studies suggest a more complex model is needed. We provide a review of the major findings from neuroimaging studies, then discuss them in relation to a heuristic model of sleep-wake states that involves three major factors: wake drive, sleep drive, and level of conscious awareness. We propose that insomnia involves dysregulation in these factors, resulting in subtle dysregulation of sleep-wake states throughout the 24 h light/dark cycle.

Electrophysiological Endophenotypes And The Error-Related Negativity (Ern) In Autism Spectrum Disorder: A Family Study, Scott A. Baldwin, Ann Clawson, Mikle South, Michael J. Larson

Faculty Publications

We examined the error-related negativity (ERN) as an endophenotype of ASD by comparing the ERN in families of ASD probands to control families. We hypothesized that ASD probands and families would display reduced-amplitude ERN relative to controls. Participants included 148 individuals within 39 families consisting of a mother, father, sibling, and proband. Robust ANOVAs revealed non-significant differences in ERN amplitude and behavioral performance among ASD probands relative to control youth. In subsequent multiple regression analyses group and kinship (proband, sibling, mother, father) did not significantly predict ΔERN (error minus correct ERN) or behavioral performance. Results do not provide evidence for …

The Enforcement Of Moral Boundaries Promotes Cooperation And Prosocial Behavior In Groups, Brent Simpson, Rob Willer, Ashley Harrell

Faculty Publications

The threat of free-riding makes the marshalling of cooperation from group members a fundamental challenge of social life. Where classical social science theory saw the enforcement of moral boundaries as a critical way by which group members regulate one another’s self-interest and build cooperation, moral judgments have most often been studied as processes internal to individuals. Here we investigate how the interpersonal expression of positive and negative moral judgments encourages cooperation in groups and prosocial behavior between group members. In a laboratory experiment, groups whose members could make moral judgments achieved greater cooperation than groups with no capacity to sanction, …

Naturally-Occurring Changes In Social-Cognitive Factors Modify Change In Physical Activity During Early Adolescence, Rod K. Dishman, Marsha Dowda, Kerry L. Mciver, Ruth P. Saunders, Russell R. Pate

Faculty Publications

Purpose

To determine whether naturally-occurring changes in children’s motives and beliefs are associated with the steep decline in physical activity observed from childhood to early adolescence.

Methods

Latent growth modeling was applied in longitudinal tests of social-cognitive influences, and their interactions, on physical activity in a large cohort of boys and girls evaluated annually between 5th and 7th grades.

Results

Measurement equivalence of motives and beliefs was confirmed between boys and girls. After adjustment for gender and maturity differences, physical activity declined less in children who reported the least decreases in self-efficacy for overcoming barriers to activity and perceived parental …

Neighborhood Environment And Falls Among Community-Dwelling Older Adults, Emily Joy Nicklett, Matthew C. Lohman Ph.D., Matthew Lee Smith

Faculty Publications

Progressive Deterioration Of Thalamic Nuclei Relates To Cortical Network Decline In Schizophrenia, Derin J. Cobia, Matthew J. Smith, Ilse Salinas, Charlene Ng, Mohktar Gado, John G. Csernansky, Lei Wang

Faculty Publications

Thalamic abnormalities are considered part of the complex pathophysiology of schizophrenia, particularly the involvement of specific thalamic nuclei. The goals of this study were to: introduce a novel atlas-based parcellation scheme for defining various thalamic nuclei; compare their integrity in a schizophrenia sample against healthy individuals at baseline and follow-up time points, as well as rates of change over time; examine relationships between the nuclei and abnormalities in known connected cortical regions; and finally, to determine if schizophreniarelated thalamic nuclei changes relate to cognitive functioning and clinical symptoms. Subjects were from a larger longitudinal 2-year follow-up study, schizophrenia (n=20) and …

Strategic Silence: Withholding Certification Status As A Hypocrisy Avoidance Tactic, W. Chad Carlos, Ben William Lewis

Faculty Publications

We examine why organizations that obtain prominent certifications may at times elect not to publicize them. Drawing on the impression management literature, we argue and show that concerns about being perceived as hypocritical may cause organizations to strategically withhold their certification status. Using a longitudinal panel of corporations that were members of the Dow Jones Sustainability Index, a prominent environmental certification, we show that in the face of reputational threats, organizations are less likely to publicize their certification status when the threat appears to directly contradict the claims implied by the certification. Our findings suggest that the threat of hypocrisy …

Norms Of Valence And Arousal For 14,031 Spanish Words, Hans Stadthagen-Gonzalez, Constance Imbault, Miguel A. Pérez Sánchez, Marc Brysbaert

Faculty Publications

Most current models of research on emotion recognize valence (how pleasant a stimulus is) and arousal (the level of activation or intensity that a stimulus elicits) as important components in the classification of affective experiences (Barrett, 1998; Kuppens, Tuerlinckx, Russell, & Barrett, 2012). Here we present a set of norms for valence and arousal for a very large set of Spanish words, including items from a variety of frequencies, semantic categories, and parts of speech, including a subset of conjugated verbs. In this regard, we found that there were significant but very small differences between the ratings for conjugations of …

Commentary: "How Much Is That Player In The Window? The One With The Early Birthday?" Relative Age Influences The Value Of The Best Soccer Players, But Not The Best Businesspeople, Luca Fumarco, Benjamin G. Gibbs

Faculty Publications

Fuelled by Gladwell's (2008), researchers have expanded their gaze beyond sports for evidence of the Relative Age Effect: that something as arbitrary as the month you were born in has important consequence for later life success. In line with Furley et al. (2016), we agree that any RAE outside of sports deserves closer scrutiny, but unlike Furley et al., we argue that we should not expect to find evidence of RAE for labor market outcomes in the first place, because there is not sufficient evidence of uniform age cut-offs in school.

Tweeting #Justice: Audio-Visual Coverage Of Court Proceedings In A World Of Shifting Technology, Itay Ravid

Faculty Publications

The debate over whether to allow cameras into courtrooms refuses to fade away. In 2015 alone, U.S. federal courts completed a five-year experiment with cameras in courts, New Zealand published new guidelines for audio-visual coverage, and Scotland completely revised its former broadcast policy. These jurisdictions, and others around the globe, constantly struggle to design model practices that successfully balance freedom of the press, transparency, and public access to information, with rights to a fair trial and privacy. The constant need to rethink coverage policies can be attributed in large part to the advancement of technology, providing the media innovative tools …

Hair Measurements Of Cortisol, Dhea, And Dhea To Cortisol Ratio As Biomarkers Of Chronic Stress Among People Living With Hiv In China: Known-Group Validation, Shan Qiao Ph.D., Xiaoming Li, Samuele Zilioli, Zheng Chen, Huihua Deng, Juxian Pan, Weigui Guo

Faculty Publications

Background

Existing literature suggests that endocrine measures, including the steroid hormones of cortisol and Dehydroepiandrosterone (DHEA), as well as the DHEA to cortisol ratio in the human hair can be used as promising biomarkers of chronic stress among humans. However, data are limited regarding the validity of these measures as biomarkers of chronic stress among people living with HIV (PLWH), whose endocrine system or hypothalamic pituitary adrenal (HPA) axis may be affected by HIV infection and/or antiretroviral therapy (ART) medications.

Method

Using hair sample data and self-reported survey from 60 PLWH in China, we examined the validity of three endocrine …

Seventy-six subjects with MCI and 101 subjects with AD diagnosed by a multidisciplinary team were included. These two groups were also compared to a group of 177 healthy elderly control participants. Sex differences on the Rey Auditory Verbal Learning Test (RAVLT) (total and delayed recall) raw scores and Brief Visuospatial Memory TestRevised (BVMT-R) were demonstrated within …

Relational Aggression And Marital Quality: A Five-Year Longitudinal Study, Sarah M. Coyne, David A. Nelson, Jason S. Carroll, Nathan J. Smith, Chongming Yang, Hailey G. Holmgren, Chad Johnson

Faculty Publications

Relational aggression occurs in many different contexts, including in romantic relationships. The current study examined associations between two subtypes of relational aggression (love withdrawal and social sabotage) and marital quality over a 5-year time period. Participants consisted of 311 married couples who completed a number of questionnaires on relational aggression and relationship quality once a year over a 5-year period. Results revealed that relational aggression was highly stable over time and that women used more relational aggression than men. Men’s use of social sabotage and love withdrawal were bidirectionally related to both partners’ perceptions of poor marital quality over time. …

Addressing The Needs Of Transgender Military Veterans: Better Access And More Comprehensive Care, Michelle Dietert, Dianne Dentice, Zander Keig

Faculty Publications

Purpose: There is a gap in social science literature addressing issues of access and quality of care for transgender military veterans. Psychologists, medical doctors, and other health professionals are beginning to address some of the barriers present in the Department of Veterans Affairs (VA) system that affect veterans who are also transgender and intersex. Over a 7-year period, between 2006 and 2013, 2600 transgender veterans were served by the VA. Data from several surveys revealed that most transgender veterans perceive the Veterans Health Administration (VHA) to be less than accommodating for their special needs. The goal of this study …

Narrative Skills Predict Peer Adjustment Across Elementary School Years, Alice J. Davidson, Marsha D. Walton, Bhavna Kansal, Robert Cohen

Faculty Publications

The importance of peer adjustment in middle childhood coincides with developing social cognitive and discursive skills that include the ability to make personal narrative accounts. Authoring personal stories promotes attention to the sequence of events, the causal connections between events, the moral significance of what has happened, and the motives that drive human action: these skills may be critical for the establishment and maintenance of satisfying peer relationships during elementary school. The present study extended previous research by considering whether narrative skills in written stories about peer interactions predicted peer adjustment. As part of an ongoing longitudinal study, 92 children …

Working With Latinos In Rural Communities: “Nuts And Bolts”, Wilma Cordova, Aparecida De Fatima Cordeiro Dutra

Faculty Publications

Latinos currently compromise 16% of the entire U.S. population and 9.3% live in rural areas ((U.S. Census, 2010). These current percentages indicate that most social workers will work with this population at least once during their careers. Therefore, it is important that social workers develop skills and knowledge to work effectively with Latinos. Working with Latinos in our current sociopolitical climate poses many challenges for social workers working in rural areas. However, if social workers adhere to the guidelines and standards initially established by the profession and implement best practices many of their efforts will be successful. This chapter aims …

Entrepreneurship In Off-Label Drug Prescription: Just What The Doctor Ordered!, Raymond March

Faculty Publications

This paper finds that physicians and pharmaceutical companies working as entrepreneurial actors were able to better serve patients by finding effective alternative uses of three drugs. I examine off-label drug prescription within an entrepreneurial framework by examining the development processes of aspirin, Viagra, and minoxidil. In each case, the medical community reached research and treatment conclusions quicker than the FDA did. These examples provide counterevidence to the view that off-label prescription is reckless and requires additional governmental oversight due to a lack of sufficient testing
