The Effects of Child Abuse and Exposure to Domestic Violence on Adolescent Internalizing and Externalizing Behavior Problems

This study examines the effects of child abuse and domestic violence exposure in childhood on adolescent internalizing and externalizing behaviors. Data for this analysis are from the Lehigh Longitudinal Study, a prospective study of 457 youth addressing outcomes of family violence and resilience in individuals and families. Results show that child abuse, domestic violence, and both in combination (i.e., dual exposure) increase a child’s risk for internalizing and externalizing outcomes in adolescence. When accounting for risk factors associated with additional stressors in the family and surrounding environment, only those children with dual exposure had an elevated risk of the tested outcomes compared to non-exposed youth. However, while there were some observable differences in the prediction of outcomes for children with dual exposure compared to those with single exposure (i.e., abuse only or exposure to domestic violence only), these difference were not statistically significant. Analyses showed that the effects of exposure for boys and girls are statistically comparable.     

Group-Based Dominance and Opposition to Equality Correspond to Different Psychological Motives

Social Dominance Orientation, one of the most popular individual differences measures in the study of generalized prejudice, can be understood as having two components: Opposition to Equality (OEQ) and support for Group-Based Dominance (GBD). We consider these components in terms of system justification theory and social identity theory. We find that each component best explains different kinds of political views, consistent with the theory that they arise from different motivations. OEQ reflects system justification motives. It better predicts attitudes towards redistributive social policy, political conservatism, and a lack of humanitarian compassion for the disadvantaged. GBD reflects social identity motives. It is more associated with hostility toward outgroups and concerns about intergroup competition. GBD and OEQ have different personality and demographic correlates, exhibit distinctive relations with explicit and implicit attitudinal preferences, and differentially predict a variety of policy attitudes. Use of GBD and OEQ as separate constructs enriches the understanding of prejudice, policy attitudes, and political ideology.     

Signature Profiling and Classification of Illicit Heroin by GC-MS Analysis of Acidic and Neutral Manufacturing Impurities

Abstract:  The illicit manufacture of heroin results in the formation of trace level acidic and neutral impurities. These impurities are detectable in illicit heroin and provide valuable information about the manufacturing process used. The isolation, derivatization, and semiquantitative analysis of neutral and acidic heroin manufacturing impurities by programmed temperature vaporizing injector-gas chromatography-mass spectrometry (PTV-GC-MS) is described. Trace acidic and neutral heroin impurities were isolated from basic fractions using liquid–liquid extraction. Extracted impurities were treated with N -Methyl- N -trimethylsilyltrifluoroacetamide followed by PTV-GC-MS analyses. Semiquantitative data were obtained using full scan mass spectrometry utilizing unique ions or ion combinations for 36 trace impurities found in crude and/or highly refined heroin samples. Minimum detection limits for acidic and neutral impurities were estimated to be at the 10⁻⁷ level relative to total morphine. Over 500 authentic heroin samples from South America, Mexico, Southwest Asia, and Southeast Asia were analyzed. Classification of illicit heroin based on the presence or absence and relative amounts of acidic and neutral impurities is presented.     

Patterns of family interaction and adolescent sex role concepts

This study examined the relationship between patterns of family interaction and adolescent development of sex role concepts. Sixty-six families of high school seniors completed a measure of daily family activities and a Plan Something Together Task, used to measure individuation in family communication. Adolescents' responses on the sex roles section of the Ego Identity Interview were coded to reflect Block's theory of the stages of development of sex role concepts. Results indicated gender differences in the development of sex role concepts as related to distinctive patterns of family communication and daily activity with the adolescents' mothers and fathers.This work was supported by grants from the National Institute of Child Health and Human Development (HD-29819 and HD-17983), the Hogg Foundation for Mental Health, and the University Research Institute and Institute of Human Development and Family Studies of the University of Texas at Austin.Received degree from the University of Texas at Austin.

The “Hired Gun” Effect: Assessing the Effect of Pay,Frequency of Testifying,and Credentials on the Perception of Expert Testimony

Three experiments addressed the proposition that jurors use short cuts in processing information when confronted with expert scientific testimony. The results of the first two studies demonstrated that experts who are highly paid for their testimony and who testify frequently are perceived as hired guns. They are neither liked nor believed. The results of the third experiment replicated the hired gun effect and showed that it is most likely to occur when the testimony is complex and cannot be easily processed. The results were discussed in terms of the theoretical differences between central and peripheral processing of persuasive messages in a legal context.     

Achievement motivation,socialization, and hypnotic susceptibility among youths from four Israeli subcultures

Based on London's theoretical model, results of a developmental study of Israeli children from four subcultures are reported. The impact of child-rearing practices on achievement motivation, hypnotic susceptibility, and brain wave patterns of subjects from Eastern European, Kurdish, Yemenite, and Moroccan backgrounds was tested and compared according to age level. Subjects were 15 children from each subcultural group. Five in each subcultural group were between 7 and 9 years old, five between 9 and 11, and five between 11 and 13. Instruments included a combined EEG-hypnotic scale, six measures of achievement and nAch, and the Winterbottom questionnaire. Subjects of European background, presumably with the highest nAch, had the lowest mean score in hypnotic susceptibility, while children of Moroccan descent, presumably the lowest achievement group, had the highest mean susceptibility score among the four subgroups as expected. It was also found, consistent with previous developmental studies of American children, that hypnotic susceptibility increases significantly with age regardless of subcultural grouping. While the four subgroups differed significantly in their school performance as expected, they did not differ in their need achievement scores. Findings in regard to EEG data are presently not reported because of technical difficulties encountered during recording. Implications for future research pertaining to methodological and theoretical issues involved in testing the model cross-culturally are discussed.This research was supported by the research committee of the Paul Baerwald School of Social Work of the Hebrew University of Jerusalem, Israel, and by National Institute of Mental Health Grant No. 53-4873-6748.Received B.A. from the Hebrew University of Jerusalem, M.S.W. from New York University, and doctorate and subsequent postdoctoral training from the University of California, Berkeley.
