The role that parental authority patterns and social-cognitive identity styles may play in establishing identity commitments was investigated. The results indicated that family authority and identity style variables combined accounted for 50% of the variation in strength of identity commitment. As hypothesized, the relationship between parental authority and identity commitment was mediated by identity style. The findings are consistent with the view that family authority patterns may contribute to the way in which late adolescents negotiate the task of constructing a sense of identity. Alternative explanations of the findings are considered. 相似文献

This article analyses how federalism matters for the policy‐designing process and the resulting policies in the field of Assisted Reproductive Technology through the comparison of four countries, Switzerland, Germany, Belgium and Canada. It reconstructs from an actor‐centred perspective how federalism interacts with other country and policy‐field specific characteristics and empirically assesses how this interaction influenced the final policies. By focusing on Assisted Reproductive Technology, the article examines the potential influence of federalism on public policies beyond the standard discussion of the comparative political economy of federalism. 相似文献

This study investigated South African Afrikaans-, English-, and Xhosa-speaking secondary school adolescents' (N = 1217) perceptions of the relative importance of identity-related domains. For this purpose a structured questionnaire consisting of 14 domain-specific items was used. Most of the domains were regarded as very important or fairly important by a significant majority of participants. Four domains were regarded as very important by more than 70% of the total research group, namely, future career, moral values, family relationships, and religious matters. Political and sexual matters were regarded as of least importance. Intercultural differences were evident in most domains. Significant gender differences were also found. Relatively more females than males reported a high priority to domains such as future career, moral values, friendships with same sex peers, gender role, and community matters. The male participants regarded relationships with the opposite sex and sexual matters as more important than the females did. The findings of this study emphasize the importance of carefully considering the domains included in future research on identity formation, depending on variables such as socioeconomic and sociocultural characteristics of the specific research groups to be included in the investigation. 相似文献

This paper identifies spatial patterns of county-level presidential election outcomes from 1988 to 2000, and tests the retrospective (reward–punishment) and issue–priority models of voting behavior within the context of county-level geographical clusters. Based on our spatial analyses, we find that: the geographical concentration of the partisan vote has increased at both the global and regional scales. Globally, counties have become more likely to be clustered with similar counties in terms of their partisan support. Regionally, Democrats have increasingly received more votes from the East and the urban areas than Republican candidates while the opposite is true in the West and the rural areas. The regression analyses also support aspects of the issue–priority model of voting behavior, while the retrospective theory is confirmed only for 1996. 相似文献
