Psychometric Assessment Of The Comprehensive Effects Of Alcohol Questionnaire: Comparing A Brief Version To The Original Full Scale, Lindsay S. Ham, Sherry H. Stewart, Peter J. Norton, Debra A. Hope
Department of Psychology: Faculty Publications
The current set of studies compared the psychometric properties of the original Comprehensive Effects of Alcohol Questionnaire (CEOA) to a 15-item version (B-CEOA) in a nonclinical undergraduate sample (N = 581), and attempted to replicate and extend the B-CEOA findings in an undergraduate sample referred to an alcohol intervention (N = 734). Psychometric assessment included construct validity, internal consistency, and concurrent validity, using both “positive” and “negative” expectancy items in all analyses. Results provided further support for the empirical validity of the original CEOA, and provided support for the use of the B-CEOA despite the reduction in the …
K-Means Clustering With Multiresolution Peak Detection, Guanshan Yu, Leen-Kiat Soh, Alan B. Bond
K-Means Clustering With Multiresolution Peak Detection, Guanshan Yu, Leen-Kiat Soh, Alan B. Bond
Avian Cognition Papers
Clustering is a practical data mining approach of pattern detection. Because of the sensitivity of initial conditions, k-means clustering often suffers from low clustering performance. We present a procedure to refine initial conditions of k-means clustering by analyzing density distributions of a data set before estimating the number of clusters k necessary for the data set, as well as the positions of the initial centroids of the clusters. We demonstrate that this approach indeed improves the accuracy and performance of k-means clustering measured by average intra to interclustering error ratio. This method is applied to the virtual ecology project to …

Wonderwise 4-H: Women in Science Learning Kits, recently included in the National 4-H Curriculum Collection and widely tested by 4-H leaders, have positively affected youths’ perspectives on science, scientists, and scientific work. Adult leaders who used the multimedia, inquiry-based Wonderwise 4-H kits completed a Web survey describing the impact of the kits on youth. It indicated that the kits increased youth’s interest and understanding of science, broadened their view of scientists, and opened their eyes to the possibility of science in their own futures. More information about Wonderwise 4-H and downloadable activities are available at wonderwise.unl.edu.

Wonderwise 4-H: Women in Science introduces youth to contemporary female scientists in their labs, out in the field, and with their families through nine interactive multimedia kits. Youth learn about the scientist’s occupation and participate in hands-on science activities similar to the actual work of a female scientist role model. Using role models was effective in improving youths’ attitudes about science through engaging activities and realistic videos. A web survey of 150 adult youth leaders showed Wonderwise 4-H brings “real science” into youths’ lives by (a) engaging them in actual scientific activities, (b) increasing their understanding of what science is, …
Gender Differences In Social Support For Socially Anxious Individuals, Lindsay Ham, Sarah A. Hayes, Debra A. Hope
Gender Differences In Social Support For Socially Anxious Individuals, Lindsay Ham, Sarah A. Hayes, Debra A. Hope
Department of Psychology: Faculty Publications
Given that social anxiety disorder is a common, chronic, debilitating disorder and socially anxious women appear to have different experiences related to social development and social support than men, it is essential that the gender differences in social anxiety and social support be understood. The present study examined perceived social support quantity and satisfaction in 23 women and 28 men seeking treatment for social anxiety disorder. Contrary to expectations, men and women did not differ on measures of social support. However, younger, unmarried women reported having smaller social support networks and less satisfaction with their social support networks than older, …
Identity As A Source Of Moral Motivation, Sam A. Hardy, Gustavo Carlo
Identity As A Source Of Moral Motivation, Sam A. Hardy, Gustavo Carlo
Department of Psychology: Faculty Publications
Theory and research regarding moral motivation has focused for decades on the roles of moral reasoning and, to some extent, moral emotion. Recently, however, several models of morality have positioned identity as an additional important source of moral motivation. An individual has a moral identity to the extent that he or she has constructed his or her sense of self around moral concerns (e.g., moral values). This paper reviews theory and research linking moral identity to moral behavior and commitment. Additionally, it suggests several key unanswered questions about moral identity and provides recommendations for future research.

A substantial number of children in foster care exhibit psychiatric difficulties. Recent epidemiologi-cal and historical trends in foster care, clinical findings about the adjustment of children in foster care, and adult outcomes are reviewed, followed by a description of current approaches to treatment and extant empirical support. Available interventions for these children can be categorized as either symptom-focused or systemic, with empirical support for specific methods ranging from scant to substantial. Even with treatment, behavioral and emotional problems often persist into adulthood, resulting in poor functional outcomes. We suggest that self-regulation may be an important mediat-ing factor in the appearance …
Incorporating Social Anxiety Into A Model Of College Student Problematic Drinking, Lindsay S. Ham, Debra A. Hope
Incorporating Social Anxiety Into A Model Of College Student Problematic Drinking, Lindsay S. Ham, Debra A. Hope
Department of Psychology: Faculty Publications
College problem drinking and social anxiety are significant public health concerns with highly negative consequences. College students are faced with a variety of novel social situations and situations encouraging alcohol consumption. The current study involved developing a path model of college problem drinking, including social anxiety, in 316 college students referred to an alcohol intervention due to a campus alcohol violation. Contrary to hypotheses, social anxiety generally had an inverse relationship with problem drinking. As expected, perceived drinking norms had important positive, direct effects on drinking variables. However, the results generally did not support the hypotheses regarding the mediating or …
