Discriminant Construct Validity Of Impact™: A Companion Study, Arthur C. Maerlender, L. Flashman, A. Kessler, S. Kumbhani, R. Greenwald, Dartmouth College Toteson, T. Mcallister

Department of Psychology: Faculty Publications

In a previous analysis of ImPACT scores relative to traditional neuropsychological tests (NP) and experimental tasks (Maerlender et al., 2010) we demonstrated convergent construct validity for the primary ImPACT test-score composites. A complete analysis of discriminant validity was not undertaken at that time. Here, test scores from the 54 collegiate football and hockey players were re-analyzed to specifically address the discriminant validity of the ImPACT composite scores using a multiply operationalized correlation matrix of multitrait multi-method data. In the method used here, discriminant validity is determined by obtaining non-significant correlations between a target score when correlated with the average of …

Olanzapine Sensitization And Clozapine Tolerance: From Adolescence To Adulthood In The Conditioned Avoidance Response Model, Jing Qiao, Hong Li, Ming Li

Department of Psychology: Faculty Publications

Disruption of conditioned avoidance response (CAR) in rodents is one trademark feature of many antipsychotic drugs. In adult rats, repeated olanzapine (OLZ) treatment causes an enhanced disruption of avoidance response (sensitization), whereas repeated clozapine (CLZ) treatment causes a decreased disruption (tolerance). The present study addressed (1) whether OLZ sensitization and CLZ tolerance can be induced in adolescent rats, and (2) the extent to which OLZ sensitization and CLZ tolerance induced in adolescence persists into adulthood. Male adolescent Sprague–Dawley rats (approximate postnatal days (BP) 43–47) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10 or 20 …

Avoidance Disruptive Effect Of Clozapine And Olanzapine Is Potentiated By Increasing The Test Trials: Further Test Of The Motivational Salience Hypothesis, Min Feng, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

Antipsychotic drugs suppress animals’ ability to avoid an aversive stimulus in the conditioned avoidance response model (CAR). This behavioral effect is thought to reflect antipsychotic activity and is suggested to be mediated by a drug’s action in attenuating the motivational salience of a conditioned stimulus (CS). In the present study, we tested whether atypical antipsychotic drugs clozapine and olanzapine act through this behavioral mechanism by manipulating the number of avoidance test trials. We reasoned that more CS trials in the present of clozapine or olanzapine would afford the drug more opportunities to decrease the motivational salience of the CS, thus …

Interoceptive Conditioning In Rats: Effects Of Using A Single Training Dose Or A Set Of 5 Different Doses Of Nicotine, Steven T. Pittenger, Rick A. Bevins

Department of Psychology: Faculty Publications

Interoceptive conditioning contributes to the tenacity of nicotine dependence. Previous research investigating nicotine as an interoceptive stimulus has typically employed administration of a single training dose of nicotine over an extended time. This approach has allowed for careful study of the nicotine stimulus. In humans, the nicotine stimulus is unlikely to be fixed across learning episodes. Thus, from a translational perspective, systematic variation of nicotine dose in training might better approximate interoceptive conditioning in humans. Notably, training with a class or set of discrete exteroceptive stimuli (e.g., different pictures of cars) produces interesting behavioral differences relative to training with a …

On Consistency Of Self- And Proxy-Reported Regular Smoking Initiation Age, Julia N. Soulakova, Brianna C. Bright, Lisa J. Crockett

Department of Psychology: Faculty Publications

Early onset of smoking is associated with heavier tobacco consumption and longer smoking careers. Consequently, obtaining accurate estimates of early smoking is a priority. The purpose of this study was to examine the utility of proxy reports of the age of smoking initiation, and specifically to explore whether there are differences in the consistency of proxy-reported and self-reported smoking behaviors. Data came from the 2002–2003 Tobacco Use Supplement to the Current Population Survey, where the current smoking behaviors and smoking history of participants were reported by self-and proxy-respondents on two occasions, one year apart. Sequential multiple-testing methods were used to …

Adolescents Occupational And Educational Goals: A Test Of Reciprocal Relations, Sarah J. Beal, Lisa J. Crockett

Department of Psychology: Faculty Publications

During adolescence, young people’s future aspirations and expectations begin to crystallize, especially in the domains of education and occupation. Much of the research in this area has emphasized development within a particular domain (e.g., education) and relations between aspirations and expectations across domains remain largely unexplored, resulting in a lack of information on how goals develop in tandem and affect each other. It is also unclear whether these developmental processes differ by gender and socioeconomic status. We tested reciprocal effects between occupational and educational goals using a longitudinal sample of 636 adolescents (52% boys). Results from dynamic systems models indicated …

Perceptions Of Campus Climate By Sexual Minorities, Patricia A. Tetreault, Ryan Fette, Peter C. Meidlinger, Debra A. Hope

Department of Psychology: Faculty Publications

Previous research has indicated that students who identify as lesbian, gay, bisexual, or transgender (LGBT) often have negative experiences on university campuses due to their sexual orientation or gender identity. Direct and indirect experiences contribute to an overall perception of the campus climate. This study used an online survey to assess students’ perceptions of campus climate, their experiences confronting bias, support of family members and friends, and whether they had considered leaving campus. Multiple regression analysis indicated that perceptions of poorer campus climate were predicted by greater unfair treatment by instructors, more impact from anti-lesbian, gay, bisexual, transgender, or queer …

Will The Real Reasonable Person Please Stand Up? Using Psychology To Better Understand And Apply The Reasonable Person Standard, Ashley M. Votruba

Department of Psychology: Faculty Publications

This article will consist of four main parts. Part I will review the historical and current Reasonable Person Standard. More specifically, it will discuss a brief history of the common law negligence standard leading to the current commonly used Reasonable Person Standard, review the current American Law Institute ("ALI") language of the Reasonable Person Standard, and briefly outline the three most common legal theorist conceptualizations of the negligence standard in order to provide a review of the current understanding of the negligence standard. Part II will then examine the importance of the jury and the limited instruction they are provided …

Brain Mechanisms Underlying The Impact Of Attachment-Related Stress On Social Cognition, Tobias Nolte, Danielle Z. Bolling, Caitlin M. Hudac, Peter Fonagy, Linda Mayes, Kevin A. Pelphrey

Department of Psychology: Faculty Publications

Mentalizing, in particular the successful attribution of complex mental states to others, is crucial for navigating social interactions. This ability is highly influenced by external factors within one’s daily life, such as stress. We investigated the impact of stress on the brain basis of mentalization in adults. Using a novel modification of the Reading the Mind in the Eyes Test (RMET-R) we compared the differential effects of two personalized stress induction procedures: a general stress induction (GSI) and an attachment-related stress induction (ASI). Participants performed the RMET-R at baseline and after each of the two inductions. Baseline results replicated and …

Fathers, Divorce, And Child Custody, Matthew M. Stevenson, Sanford L. Braver, Ira M. Ellman, Ashley M. Votruba

Department of Psychology: Faculty Publications

A great many fathers will have their fathering eliminated, disrupted, or vastly changed because they become divorced from the child’s mother. In fact, between 40% and 50% of marriages end in divorce (Cherlin, 2010). Although the divorce rate (measured as divorces per 1,000 people) is high by the standards prior to the late 1960s, it has actually fallen more than 30% since its peak in 1980. The decline in divorce rates in recent years has, however, been concentrated among the college-educated portion of the population; divorce rates among the less well educated may have even increased (Cherlin, 2010). But for …

Candidate Genes And Voter Turnout: Further Evidence On The Role Of 5-Httlpr, Kristen Diane Deppe, Scott F. Stoltenberg, Kevin B. Smith, John R. Hibbing

Department of Political Science: Faculty Publications

Recently in this journal, Charney and English (2012) presented an extensive critique of candidate gene association studies using the widely noted Fowler and Dawes (2008) article on the relationship between self-reported voter turnout and both 5-HTT (serotonin transporter) and MAOA (monoamine oxidase A) as the driving example of their evaluation. Reanalysis of the Fowler and Dawes data by Charney and English, based on four critiques of candidate gene studies, led to the conclusion that neither polymorphism is related to variations in turnout.We add to this empirical debate by conducting an independent test using an original dataset containing 5-HTT data and …

From Mounds To Maps To Models: Visualizing Ancient Architecture Across Landscapes, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

Since the onset of settlement pattern studies in the 1950s, landscape mapping projects have become an archaeological mainstay. Remote sensing technologies such as lidar, photogrammetry, and SAR (Synthetic Aperture Radar) steadily reveal new archaeological sites. For landscape archaeology, the detection and mapping of small architectural complexes and households offers important data to contextualize larger (often already known) sites and perform regional analyses. However, because the majority of sites remain unexcavated, analysis is limited, and yet Geographic Information Systems (GIS) and 3D Visualization are expanding the possible uses for older and newly-acquired data on unexcavated mounds. This paper describes a GIS …

Sex Differences In Adult Cognitive Deficits After Adolescent Nicotine Exposure In Rats, Laura R.G. Pickens, James D. Rowan, Rick A. Bevins, Stephen B. Fountain

Department of Psychology: Faculty Publications

This study was designed to determine whether deficits in adult serial pattern learning caused by adolescent nicotine exposure persist as impairments in asymptotic performance, whether adolescent nicotine exposure differentially retards learning about pattern elements that are inconsistent with “perfect” pattern structure, and whether there are sex differences in rats’ response to adolescent nicotine exposure as assessed by a serial multiple choice task. The current study replicated the results of our initial report (Fountain, Rowan, Kelley, Willey, & Nolley, 2008) using this task by showing that adolescent nicotine exposure (1.0 mg/kg/day nicotine for 35 days) produced a specific cognitive impairment in …

Justice League? Depictions Of Justice In Children’S Superhero Cartoons, Lisa A. Kort-Butler

Department of Sociology: Faculty Publications

The literature argues that media depictions of criminal justice present messages that conform to and promote the dominant ideology about the crime problem and how to solve it. Research has focused on television news and adult programs, but little research has examined messages about justice present in children’s shows. To fill this gap, an ethnographic content analysis of children’s cartoons was conducted, using a sample of episodes from Batman: The Animated Series, Spider-Man, and Justice League Unlimited. Several themes emerged. First, the justice system is often depicted as ill equipped to handle serious crime. Second, story lines suggested that the …

The Relationship Between Victimization And Substance Use Among Homeless And Runaway Female Adolescents, Kimberly A. Tyler, Sarah Gervais, Meghan Davidson

Department of Sociology: Faculty Publications

Each year, thousands of female adolescents run away from home due to sexual abuse yet they continue to be victims of sexual assault once on the street. To date, few studies have examined how various forms of victimization are related to different types of substance use. The purpose of this paper is to investigate the relationship between street exposure, childhood abuse, and different forms of street victimization with alcohol and marijuana use among 137 homeless and runaway female adolescents. Results from path analysis revealed that child sexual abuse was positively linked to trading sex and sexual and physical victimization. Additionally, …

Out On The Land: Income, Subsistence Activities, And Food Sharing Networks In Nain, Labrador, Kirk Dombrowski, Emily Channell, Bilal Khan, Joshua Moses, Evan Misshula

Department of Sociology: Faculty Publications

In recent Inuit ethnography, a major concern has been how and to what extent contemporary Inuit participate in and depend on subsistence activities, particularly in the context of increasing wage employment and growing participation in the cash economy. This paper provides an analysis of these activities in the predominately Inuit community of Nain, Labrador. Using social network data and demographic information collected between January and June 2010, we examine the interconnections between subsistence activities—obtaining “country food” through activities such as hunting, fishing, and collecting—with access to the means of obtaining subsistence resources (such as snow mobiles, cabins, and boats), employment …

Theories Of Public Opinion, Patricia Moy, Brandon Bosch

Department of Sociology: Faculty Publications

While the issue of citizen competency has vexed scholars throughout history, the modern concepts of a mass public and mass media are relatively new. Beginning with the seminal works of Lippmann and Dewey, we chart the evolving theories of public opinion, from the "hypodermic needle" model of the early twentieth century to the more psychologically oriented approach to media effects of today. We argue that in addition to understanding how audiences process media content, theories of public opinion must account for how media content is constructed and disseminated, which is complicated by the ever-changing nature of our media landscape.

Structural Effects Of Network Sampling Coverage I: Nodes Missing At Random, Jeffrey A. Smith, James Moody

Department of Sociology: Faculty Publications

Network measures assume a census of a well-bounded population. This level of coverage is rarely achieved in practice, however, and we have only limited information on the robustness of network measures to incomplete coverage. This paper examines the effect of node-level missingness on 4 classes of network measures: centrality, centralization, topology and homophily across a diverse sample of 12 empirical networks. We use a Monte Carlo simulation process to generate data with known levels of missingness and compare the resulting network scores to their known starting values. As with past studies (Borgatti et al., 2006; Kossinets, 2006), we find that …

Conservation Compliance Under The House And Senate Versions Of The 2013 Farm Bill: A Role For Empathy Nudging?, Hans J. Czap, Natalia Czap, Gary D. Lynne, Mark E. Burbach

Cornhusker Economics

Current and past farming practices have led to significant environmental degradation in the form of soil erosion (sediments), as well as fertilizer and chemical related water pollution. The United States Department of Agriculture (USDA) has long tried to implement policies to temper such negative effects on the environment. The 2008 Farm Bill which currently guides agricultural and related environmental/conservation policy is being revised on this front. The United States Senate and the House of Representatives are each currently proposing a version of the 2013 Farm Bill to change the existing system, making it more efficient in achieving environmental (and other …

Achieving Integration In Mixed Methods Designs—Principles And Practices, Michael D. Fetters, Leslie A. Curry, John W. Creswell

Department of Educational Psychology: Faculty Publications

Mixed methods research offers powerful tools for investigating complex processes and systems in health and health care. This article describes integration principles and practices at three levels in mixed methods research and provides illustrative examples. Integration at the study design level occurs through three basic mixed method designs—exploratory sequential, explanatory sequential, and convergent—and through four advanced frameworks—multistage, intervention, case study, and participatory. Integration at the methods level occurs through four approaches. In connecting, one database links to the other through sampling. With building, one database informs the data collection approach of the other. When merging, the two databases are brought …

Assessing Connections Between Young Children’S Affinity For Nature And Their Experiences In Natural Outdoor Settings In Preschools, Camilla S. Rice, Julia C. Torquati

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

The purposes of this research were to: develop a reliable measure of children’s affinity for nature or “biophilia”; determine whether young children’s biophilia was related to the “green-ness” of the outdoor play area of the preschool they attend; examine whether demographic variables are associated with children’s biophilia; and determine whether demographic variables predict children’s enrollment in nature-oriented programs. We recruited children from ten early childhood education programs—six that had outdoor play spaces with many natural elements and four that had few or none of these elements. One hundred fourteen preschool-aged children completed an 11-item measure of biophilia that included preferences …

Beyond The Walls: Conceptualizing Natural Environments As “Third Educators”, Julia C. Torquati, Julie A. Ernst

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

This research examined preservice early childhood educators’ perceptions of outdoor settings and their intentions to use outdoor settings in their teaching practice. Students enrolled in an early childhood education program (n = 110) at a university in the Great Lakes region completed surveys that assessed perceptions of natural settings, intentions to use natural settings in future teaching, knowledge of the benefits of nature for children, and personal nature relatedness. Participants reported relatively high intentions to use natural settings in future teaching, as well as knowledge of the benefits of nature for children, but moderate levels of personal nature relatedness. Participants …

Spiritual Well-Being And Its Relationship To Resilience In Young People: A Mixed Methods Case Study, Lindsay Smith, Ruth Webber, Erica Defrain

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

Questions have arisen recently about the role of spiritual well-being in strengthening resilience of youth. To explore this association, this case study focused on the relationships and connectedness of young people who attend one religious organization as a means of enhancing their spiritual well-being. In line with the purposes of an instrumental case study, different sources of data (quantitative and qualitative) were collected on the phenomenon of interest—spiritual well-being. A theoretical purposive sample of 65 people participated in the study. A mixed methods research approach guided this case study, which incorporated both single- and multicase study techniques. Through an abductive …

Nebraska Students In Transition: The Evolution Of A Partnership, Toni Anaya, Charlene Maxey-Harris

University of Nebraska-Lincoln Libraries: Faculty Publications

Since 2010, the University of Nebraska-Lincoln (UNL) libraries have been collaborating with the Office of Admissions on an innovative program working with high school seniors through the Nebraska College Preparatory Academy (NCPA). Over the past 10 years, Nebraska has been affected by Nebraska's dramatic changes in racial and ethnic diversity. Despite a rapid rise in ethnic diversity over the past 10 years, the state was still 90 percent white at the time of the 2010 census. Over the past decade, UNL has been interested in actively recruiting students and faculty from ethnically diverse backgrounds. This initiative centers on recruitment strategies …

Gendered Narratives Of Innovation Through Competition: Lessons From Science And Technology Studies, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

Library and information science is a technologically intensive profession with a high percentage of women, unlike computer science and other male-dominated fields. On the occasion of the 2011 Association for Library and Information Science Education (ALISE) conference, this essay analyzes the theme “Competitiveness and Innovation” through a review of social psychology and science and technology studies literature. Both theme concepts have ramifications for library and information science (LIS) education. Librarianship and teaching are both professions that resist commodification because they rely on embodied labor and personal interaction. Competition, as a management or learning style, may not promote meaningful innovation in …

Connecting With Volunteers: Memorable Messages And Volunteer Identification, Sarah Steimel

Department of Communication Studies: Faculty Publications

Many of the 1.8 million registered nonprofit organizations in the United States rely on the services of volunteers to be able to connect with and meaningfully serve their communities. However, volunteers are less likely to receive formal socialization and training than paid employees. Thus, this study employs the concept of memorable messages as a way for exploring the ways in which messages received by volunteers from a variety of organizational sources may affect their volunteer identification with the nonprofit organization they serve. Three results emerged from the data, including: (a) sources of memorable messages in volunteer organizations; (b) types of …

The Experience And Expression Of Stepchildren’S Emotions At Critical Events In Stepfamily Life, Sandra Metts, Dawn O. Braithwaite, Paul Schrodt, Tiffany R. Wang, Amanda J. Holman, Audra K. Nuru, Jenna Stephenson Abetz

Department of Communication Studies: Faculty Publications

This study explored the experience and expression of emotions of adult stepchildren during four critical events in stepfamily life. During semistructured, in-depth interviews, 57 adult stepchildren shared stories about four critical events: the parental divorce, remarriage of one of the parents, an event in the stepfamily that generated feeling more like a family, and an event in the stepfamily that generated feeling less like a family. A total of 402 pages of single- spaced transcripts were coded for emotion, target, and expression of emotion resulting in positive and negative emotion categories and subcategories for all four critical events. Five research …
