This study examined the nature and correlates of different patterns of perceived control in adolescents' relationships with their best friends. Participants included firstborn adolescents (M = 14.94 years), their younger siblings (M = 12.44 years) and both their mothers and fathers in 163 families as well as a best friend of each adolescent (M = 15 years). Data were collected from family members during home visits regarding adolescents' family relationships, friendships, and psychosocial adjustment; time use data were gathered during a series of 7 nightly phone interviews. Information was obtained from best friends during a brief phone interview. We developed a typology of 3 different patterns of perceived friendship control based on the combination of adolescents' and their best friends' ratings of relational control. Patterns of control in adolescents' friendships were associated with the distribution of control in both parents' marriages and adolescents' sibling relationships. Further analyses, designed to test developmental predictions, revealed connections between friendship control and other qualities of adolescents' friendships (i.e., intimacy, conflict, perspective-taking).  相似文献

The thaw of the Cold War ended the chess game between the superpowers and seemingly gave new momentum to the revival and spread of liberal democracy and its corollary, capitalism. Just as missionaries once offered Christianity to "save" colonised peoples, democracy has become the new gospel promising "salvation". Both donor and recipient countries appeal to democracy, hoping that it will reverse decades of misfortune. Donor nations and multilateral financial institutions preach democratic governance. "Born again democratic" national leaders in the South who are intent on clinging to power attend to their sermons. None appear to have a genuine faith in democracy. While some nations and NGOs do give altruistically, most use foreign aid as another means of pursuing their national interest. Democracy is an elastic concept. Indeed it seems, at least at this point, that the new gospel of democracy is but a convenient tool used by different players for they own selfish reasons.  相似文献

Virtually no one in the United States raised objections to the 1964 military takeover of the Brazilian civilian government. In the early 1970s, however, the Brazilian regime had become associated with torture and the arbitrary rule of law. By the end of that decade, compliance with human rights standards had developed into a yardstick for measuring U.S. foreign policy initiatives in Latin America. This paper argues that between 1969 and 1974, a small group of dedicated church activists, exiled Brazilians, and academics introduced the issue of human rights in Latin America into the U.S. national body politic. A network of concerned activists fashioned a systematic campaign to educate journalists, government officials, and the public about the abuses taking place under the generals' rule. Their activities helped isolate the military regime and laid the groundwork for a broader solidarity movement with Latin American popular struggles in the late 1970s and 1980s.  相似文献

Empathy, prosocial behavior, the number of friends, self-reported popularity, and various forms of interpersonal forgiveness were examined as predictors of peer victimization among 52 7th and 8th graders attending a private school. Popularity was the strongest individual predictor of teacher-reported victimization with high popularity associated with low victimization. Malestudents reported significantly higher rates of victimization than females, prompting the decision to examine correlates of self-reported victimization separately by gender. Interpersonal forgiveness scores were the strongest predictors of self-reported victimization; however, different forms of forgiveness were the greatest predictors of male and female self-reported victimization. Implications are discussed.  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

The current study used a person-oriented approach to examine the participation of adolescents in both constructive, organized activities as well as relaxed leisure activities. The goal of this research was to identify different profiles of involvement in activities and the relations to psychosocial indicators for these differing groups. Activity profiles were created using cluster analytic techniques for 918 adolescents' responses in 11 activity domains. The groups were found to be both statistically and substantively unique and consistent with findings from previous research. Further, the groups showed meaningful and consistent differences across a range of psychosocial indicators, including academic performance, problem behavior, and mental health. Results indicated that adolescents' activity involvement was related to their psychological and behavioral functioning and that the profiles of participation across activity settings provide a more holistic view of teens' choices than do single variable models.  相似文献

This paper focuses on parental maltreatment, a rarely documented phenomenon. We prospectively examine factors that can increase the risk of abusive behavior toward mothers. The purpose of this study is to examine the relationship between a stressful family situation, parental divorce, and verbal and physical aggression toward mothers. We use a large Canadian sample of adolescents who have been followed since kindergarten. At age 15, we assessed verbal and physical abuse toward mothers, as reported by both mothers and their adolescents. Multinomial logit modeling revealed that parental divorce was associated with a greater risk of physical aggression directed toward mothers by adolescents. Family environment and parental coping strategies partially mediated that relationship. Mothers who divorced, and remained divorced, were at greater risk of being assaulted by their adolescent children. A positive family environment, reflecting a better parent–child relationship, partially diminished this risk. However, support-seeking behavior on the part of mothers increased the risk of abuse, concurrent with tyrannical strategies often mobilized by abusive children.  相似文献
