Identity and academic motivation are particularly at stake before the major transition to higher education. However, few studies have explored their changes and their longitudinal bidirectional links. To fill this gap, a three-wave study from the end of the 11th grade to the end of the 12th grade was conducted to explore changes in identity processes and academic motivation and to investigate how they might be interconnected over time. 599 adolescents (mean age 17.4; 59% girls) completed questionnaires containing measures about identity processes and three types of academic motivation: autonomous, controlled, and impersonal. Throughout the study span of one year, four identity processes increased: commitment making, identification with commitment, exploration in breadth and exploration in depth, while the process of ruminative exploration decreased. Simultaneously, late adolescents encountered an increase in impersonal motivation, more salient for boys. The results also revealed unidirectional links from motivation to identity processes, with no gender or age moderator effects: exploration in breadth and exploration in depth were positively predicted by autonomous motivation, ruminative exploration was positively predicted by autonomous, controlled, and impersonal motivation. In addition, impersonal motivation negatively predicted commitment making. On the other hand, identification with commitment positively predicted autonomous motivation. Practical implications are discussed.

Families struggling with a breakdown in communication, trying to control the behavior of an unruly child, or experiencing a crisis often look for outside help. Many families, particularly those without resources to pay for private support, turn to their local status offense system. Status offenders are young people charged with behavior unique to their status as juveniles such as running away, truancy, or disobedience. In 2007, Congress will begin to consider reauthorization of the Juvenile Justice Delinquency Prevention Act (JJDPA), the federal act related to status‐offender policy. By providing an overview of recent state status‐offense legislation and case law, this article identifies issues to be addressed by Congress in reauthorizing the JJDPA.  相似文献

Atypical entrance gunshot wounds may be produced by deflected or ricocheting bullets. One special type of atypical entrance wound involves abrasion of the skin at a site that is remote from the point of dermal penetration. These remote abrasions, termed "tumbling abrasions," are produced by bullets that tumble after impact with an intermediate target. Three cases of tumbling abrasions are presented.  相似文献

The behavior of Bangladeshi trade unions is characterized bypolitical activism and momentous strikes, called hartalsthere, have played a crucial part in most political changes inthis country. We offer a theoretical framework for discussingthis fact, and we test empirically its main prediction bybringing out the political cycle that characterizes theoccurrence of strikes in Bangladesh.  相似文献
