For America's foes in Afghanistan and the Middle East, triumph on the battlefield is less important than winning the battle of perceptions. In response, the United States has turned to Strategic Communication and Public Diplomacy (SC-PD) to engage key audiences in ways that advance U.S. interests and to win the political-ideological contest for domestic and international legitimacy. But are these strategies effective? While winning hearts and minds is politically important, SC-PD—even at its best—is much less effective than other well-crafted and mutually supportive policies and strategies. Moreover, there are structural obstacles that greatly limit the effectiveness of SC-PD.  相似文献

The current study examined the process by which attachment to parents influences satisfaction with and ease in forming friendships at college. One hundred seventy-two female college freshmen completed a measure of parental attachment security the summer before their first semester of college (July 2006) and measures to assess satisfaction with and ease in forming close relationships at the end of their first semester (December 2006). Students ranged in age from 18 to 20 years (M = 18.09, SD = 0.33) and were diverse in their racial makeup (30% racial minority). Consistent with predictions derived from attachment theory, secure attachment to parents was positively associated with ease in forming friendships among racial minority and white participants and satisfaction with friendships among minority participants. Moreover, indirect effects of parental attachment security on relationship outcomes through social anxiety were significant for minority participants but not for white participants. Findings may be useful in the development of retention programs targeted at incoming university freshmen, particularly minority students.  相似文献

Research on the mechanisms by which interparental conflict (IPC) affects child depression suggests that both parenting and children’s conflict appraisals play important roles, but few studies have explored the role of general cognitive style or included both parenting and cognitions in the same design. Moreover, the effects of IPC on minority children are not well understood. In this longitudinal study, parenting was examined as a mediator of the relation between increasing IPC and change in depression. General cognitive style was included as a moderator. The combined influence of parenting and cognitions was also explored. A racially and ethnically diverse sample of 88 fifth and sixth graders from two urban schools reported their cognitive style, depressive symptoms, and perceptions of conflict and parenting at two time points separated by one year. Parental warmth/rejection mediated the relation between IPC and depression, and general cognitive style acted as a moderator. Parenting, cognitive style, and IPC did not significantly interact to predict change in depression over time. Findings indicate that both parenting and children’s general cognitive style play a role in understanding the impact of increasing IPC on children’s well-being.  相似文献

The political vocabulary of the Lebanese Islamist party and militia Hizbullah in relation to pluralism exhibits an important self-contradiction. In Lebanon, Hizbullah has adapted to a process of national integration after 15 years of civil war, and appears as much more positive towards pluralism now than in 1985, when it made itself known officially. However, the Palestinian resistance struggle constitutes an ever more important part of the party's political and religious identity, and in this area the party relies on a vocabulary of absolute and religiously motivated conflict. Hizbullah has made the Palestine Question into a religious absolute at the same time as it connects this question to the issue of national unity in Lebanon, questioning the patriotic credibility of every Lebanese who disagrees with it on this issue. Consequently, a conflict-oriented vocabulary ‘colonizes’ Hizbullah's more tolerant and pluralist vocabulary within Lebanon, thus hindering a further development of pluralist attitudes.  相似文献

The transition to high school has been identified as a potentially difficult time in adolescents’ lives. Reductions in both academic and social functioning often accompany this transition. While these effects have been documented in urban youth, the move to high school has not been extensively studied in rural minority youth. Toward that end, the academic grades and substance use in ninth grade of 447 (184 male and 263 female) African-American adolescents from two rural counties in a state in the deep South were examined in relation to configurations of adaptation from sixth through eighth grade. Results indicate that individual with consistently positive patterns across middle school had higher grades and lower rates of substance use compared to individuals with persistent difficulties or those that transitioned to problem behavior. Many individuals who improved in their patterns of adaptation had relatively high grades, but also rather high rates of substance use in the ninth grade. David B.
