The policy movement is unified by a common interest in the improvement of policy decisions through scientific inquiry. The movement is differentiated, however, because this common interest is highly ambiguous and subject to interpretation from different perspectives. This paper applies a policy sciences perspective to the movement's disappointments over the last few decades, and in particular, the failure to realize earlier aspirations for rational, objective analysis on the more important and controversial policy issues. The paper offers a definition and diagnosis of the underlying problem, and suggests what can be done about it as a matter of individual and collective choice.  相似文献

The association of pubertal maturation with internalizing and externalizing symptoms was examined with a sample of 867 African-American 10 – 12-year-old children. Children reported their pubertal development status and timing using a self-report questionnaire, and symptoms were assessed through diagnostic interviews with the children and their primary caregivers. Pubertal status and timing were significantly associated with children's reports of the internalizing symptoms of social anxiety disorder, generalized anxiety disorder, and major depression and with the externalizing symptoms of oppositional defiant disorder, attention deficit disorder, and conduct disorder. Pubertal development also was associated with caregivers’ reports of children's externalizing symptoms. The pubertal transition was associated with internalizing and externalizing symptoms in both boys and girls.Xiaojia Ge is Professor at the University of California, Davis.

This paper studies extremist behaviour, and its connection to authoritarianism. I divide extremists into two groups, leaders, who demand extremist acts such as assassinations, suicide terror or other forms of political violence from followers, who supply them. I assume that both the leaders of extremist groups and their followers are rational. The paper looks at three examples: Communism, Nationalism and Islamic Fundamentalism. I show that leaders with extreme ideologies also tend to adopt violent methods when there is an indivisibility between the intermediate goal of the group and its ultimate goal. Turning to followers, the most important innovation of the paper is a simple model which explains how it is possible for a person to rationally commit suicide to further the goals of a group. The most important policy implications of the paper are, firstly, that one should look at the goals of extremist group in order to understand their actions. If one can un-bundle the goal or make the indivisible divisible, then there may be ways to provide these goals in a way which satisfies some of the potential supporters of the group and thus dries up support for the grander ambitions of the leaders of extremist groups. Secondly, the provision of programs which foster social cohesion tends to dry up an important motive for extremist activity: the desire for solidarity. Thirdly, policy towards terrorists should combine the use of “carrot” and “stick”. Finally, I argue that authoritarian regimes rather than democracies or totalitarian regimes are the most likely sources of suicide terror. So democracy is indeed part of the solution to the problem of suicide terrorism.  相似文献

Abramson and Inglehart find a significant trend toward postmaterialist values in Western Europe, which they argue is largely driven by the gradual processes of generational replacement. Clarke, Dutt, and Rapkin argue that this trend is a methodological artifact of the wording of Inglehart's four-item measure of materialist/ postmaterialist values. They claim that because this battery does not include a question about unemployment, in periods of high unemployment respondents tend to choose postmaterialist goals. The long-term trend toward postmaterialism in Western Europe, they argue, results from rising levels of unemployment during the past two decades. Abramson and Inglehart point out that increases in inflation have a short-term impact on decreasing postmaterialism, but maintain that the positive relationship between unemployment and postmaterialism is spurious. As this analysis shows, Clarke, Dutt, and Rapkin find a positive relationship between unemployment and postmaterialism by building a model that has little theoretical justification and that is not robust to changes in specification. As this analysis demonstrates, unemployment is actually linked with support for materialist goals, and the trend toward post-materialism is robust in the face of alternative time frames, models, and specifications. The weight of the evidence demonstrates that the long-term trend toward postmaterialism in Western Europe is driven by generational replacement.  相似文献

The purpose of this study was to examine differences in empathy between offender and nonoffender youth. Seventy-six male and 33 female juvenile offenders between the ages of 12 and 18 years and 33 male and 33 female nonoffenders between the ages of 15 and 19 years comprised the samples for this study. Measures of empathy, altruism, and social support were administered to all participants and then the participants were analyzed for status group differences. Only 1 dimension of empathy, emotional tone, was found to be significantly different based on group status. Gender differences were found for both status groups for another dimension of empathy, personal distress. Among offender and nonoffender youth, females yielded higher scores in personal distress than did males. Emotional tone and family structure were found to be the most predictive variables of offender status. Findings were discussed based on previous research and implications for interventions were addressed.Evaluation and Special Programs  相似文献

This study explores regionalism in the appointment and decisionmakingpatterns of federal district judges. We begin with an examinationof the general appointment strategies of Ronald Reagan, JimmyCarter, and other recent presidents. The role of local constraintsin this process is emphasized. Next, the behavior of federaldistrict judges appointed by recent presidents is analyzed bycomparing levels of support for civil rights and civil libertiesclaims in cases decided during the 1977–1985 period. TheReagan appointees' support scores are compared with those ofjudges appointed by Carter and other recent Democratic and Republicanpresidents. Comparisons are made in the nation as a whole andalso across circuits and states. Our findings indicate thatthe Reagan appointees are less supportive of civil rights andliberties claims than judges named to the bench by Carter orother recent Democratic and Republican presidents.  相似文献
