Age segregation of adolescents in and out of school

In a naturalistic study of age segregation during adolescence, 403 adolescents making up 153 separate groups were observed in three high schools and seven out-of-school settings. Age segregation was extensive, especially in school, among older adolescents in same-sex groups of friends. More mixed-age association was observed out of school among younger adolescents who were in mixed-sex groups containing relatives. Adolescents were most often observed with friends who were other adolescents, next with adults, and least frequently observed with children. Parents, particularly fathers, were rarely present. It was suggested that age segregation during adolescence is the result of a lack of contact with relatives.Received his Ph.D. from Michigan State University in 1974.

Mixed-Sex Settings and the Perception of Competence

This study examines the association of self-perceptions with sixth to eighth graders' exposure to mixed-sex and dating contexts. It contrasts two hypotheses: the stress hypothesis, which suggests that the transition to romantic relationships will be associated with declines in self-esteem, especially for girls, and the leisure hypothesis, which suggests that movement into a desired role in an emotionally positive social context will be associated with positive emotions and higher self-esteem. Results indicate that adolescents experience mixed-sex settings positively, and that comfort with the other sex (for girls) and more time spent with the other sex (for boys) are predictive of more positive self-perceptions. Activity diary data suggest that these differences are due to differences in the emotional climate of same- and mixed-sex settings, rather than to the activities adolescents engage in with same- and mixed-sex groups. Dating boys who are less interested in dating experience lower self-esteem. Results are discussed in light of the transitional nature of mixed-sex relationships in early adolescence and the preparatory role played by same-sex friendships.     

AFTERWORD: CROSS-CULTURAL IMPLICATIONS OF JAPANESE HERITAGE LANGUAGE POLICIES AND PRACTICES

Scholars of regions where multiple languages are spoken have much to gain by considering heritage language education, individual identity, and state power through these ethnographic and historical cases that focus on Japan and the Japanese diaspora. The articles in this two-part collection offer insights into the interrelationships of linguistic hierarchies and political economy, the navigation of ethnic and racial subjectivities, and the ways children and adolescents claim belonging to various communities through their linguistic practices. The articles interrogate not only heritage but remembrance and the ways individuals may produce identity through language in everyday interactions and institutional settings.     

Managing incidental findings in human subjects research: analysis and recommendations.

No consensus yet exists on how to handle incidental findings (IFs) in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are findings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed.     

Das informell-kooperative Verwaltungshandeln im Umweltrecht

Zusammenfassung  Informelles Verwaltungshandeln geh?rt zum umweltrechtlichen Alltag. Die technische Entwicklung und die zunehmende Komplexit?t umweltrelevanter Sachverhalte veranlassen den Staat dazu, jenseits der hergebrachten Handlungsformen des ?ffentlichen Rechts in den wirtschaftlichen Bereich einzuwirken und das ursprünglich subordinative Staat-Bürger-Verh?ltnis in eine auf Konsens zielende Kooperation umzustrukturieren. Der vorliegende Beitrag befasst sich mit der noch nicht abschlie?end gekl?rten rechtlichen Bew?ltigung informeller staatlicher T?tigkeit. Der Schwerpunkt liegt dabei auf dem sog. normvollziehenden Verwaltungshandeln. Besondere Berücksichtigung findet die Teilformalisierung informeller Verhaltensweisen de lege lata und im Referentenentwurf zum UGB.     

Schiffe als Abfall?

Zusammenfassung In dem Beitrag geht es um die Frage, ob Seeschiffe in hiesigen H?fen, die demn?chst im Ausland abgewrackt werden sollen, unter das Ausfuhrverbot des Basler übereinkommens und der EG-Abfallverbringungsverordnung fallen. Diese Auffassung wird in Industriel?ndern aufgrund der oftmals hohen Kontamination alter Schiffe mit Giftstoffen und angesichts unzureichender Umweltund Arbeitsschutzbestimmungen in abwrackenden Entwicklungsl?ndern verschiedentlich vertreten. Die Autoren zeigen, dass das geltende Recht Auslaufverbote für solche Schiffe nicht zul?sst und weisen auf die Bemühungen der Internationalen Seeschifffahrts-Organisation um ein Schiffsrecyclingübereinkommen hin.     

Crimes committed by terrorist groups: Theory,research, and prevention

Statement of Purpose: A decline in state-sponsored terrorism has caused many terrorist organizations to resort to criminal activity as an alternative means of support. This study examines terrorists' involvement in a variety of crimes ranging from motor vehicle violations, immigration fraud, and manufacturing illegal firearms to counterfeiting, armed bank robbery, and smuggling weapons of mass destruction. Special attention is given to transnational organized crime. Crimes are analyzed through the routine activity perspective and social learning theory. These theories draw our attention to the opportunities to commit crime and the criminal skills necessary to turn opportunity into criminality. Through these lenses, the research appraises the “successes” and “failures” of terrorists' engagement in crime. Because “failures” can result from law enforcement efforts to (1) interrupt criminal skill development, and/or (2) remove criminal opportunities via technologies and transportation systems, the research represents a best practices approach to the study and control of terrorism.
