Developed on the premise that how we conceive of ‘policy’ and ‘successful policy’ guides policy sciences' research and evaluation, this paper responds to the conceptual questions of “what is a policy?” and “when is a policy successful?” Formal or logical conditions are established to distinguish ‘policy’ from related concepts. The notion ‘relevant public’ is introduced to distinguish public policies from private policies and to identify fairly-declared policies. Further, conditions are developed that can be used as logical tests for three types of policy success: implementation success, instrumental success and success in normative justification.  相似文献

The central question of this article is why indigenous social movements formed electorally viable political parties in Latin America in the 1990s. This development represents a new phenomenon in Latin America, where ethnic parties have been both rare and unpopular among voters. Institutional reforms in six South American countries are examined to see if the creation and success of these parties can be correlated with changes in electoral systems, political party registration requirements, or the administrative structure of the state. The study concludes that institutional change is likely to be a necessary but not sufficient condition for the emergence and electoral viability of ethnic parties.  相似文献

Research shows protective factors that mitigate risks for juvenile delinquency can also support the community reentry of incarcerated youths and deter future offending. Family engagement, educational attainment, and secure employment are widely accepted as important protective factors to prevent problematic behavior. Studies suggest these same protective factors are crucial for incarcerated youths and should be an integral part of reentry planning to improve post-release outcomes. Nevertheless, limited research exists on the association between these factors and the value of family involvement in reentry planning for incarcerated youths. This study addresses this gap by examining how increased family contact affects the likelihood of instituting education and employment reentry plans among youths in custody. Data were obtained from the Survey of Youth in Residential Placement (SYRP) that provides information on juvenile offenders in confinement. The SYRP is the first nationally representative cross-sectional survey to gather information directly from youths 10–20 years old in custody (N=7,073). Analyses were conducted using a sequence of regression models to test the relationship between the frequency of family contact and whether a youth had a plan for education or employment upon release. Results reflect that youths with increased family contact were one and a half times more likely to have both educational and employment reentry plans in place relative to youths with no family contact. Findings inform practice and policy to advocate for family involvement with youth in confinement, and further suggest that family plays a decisive role in preparing incarcerated youths for success upon release.  相似文献

Youth violence in America has grown to insurmountable levels. Homicide is now the third leading cause of death for youth ages 5–14, the second leading cause of death for those ages 15–24 and the number one cause of death among black males ages 15–34. With increased levels of violence and senseless killings across the nation, there is a need to explore behavioral and environmental causes of high risk behavior and various types of interventions to decrease antisocial behavior. Violence prevention should be approached comprehensively from a myriad of approaches and levels of prevention and intervention that should infiltrate individuals, homes, schools, communities and systems.

Numerous types of theories are being designed, implemented and evaluated to decrease and prevent unhealthy behaviors. While there is a need to continue to refine intervention and containment strategies, a preventative approach to addressing root causes of antisocial behaviors needs to be considered as we comprehensively look at interventions for violence prevention. The purpose of this article is to add to the body of research a theory, the Priority/ Consequence model, which depicts interrelated dynamic behavioral and societal variables that can influence, positively or negatively, attitudes, values and beliefs that establish prioritized behaviors that produce consequences.  相似文献

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

In this study, the most salient worries of Dutch adolescents are examined and the most often reported symptoms are ranked. The relationship between worrying and health is explored using structural modeling as are the frequently found gender differences in these areas. Worrying is postulated as an indicator of psychosocial well-being along with affectivity, ease of parental communications, tiredness, and loneliness. Health, or physiological status, is indicated by reported symptoms, frequency of doctors visits, aspirin consumption, and a global health measure. Four hundred and sixteen high-school students (211 girls and 205 boys) fitted in a questionnaire during school hours. The structure of the bet fitting model was the same for boys and girls, indicating that gender differences are a question of degree, and not of different structural relationships. Psychosocial well-being explained 77% of the variance in physiological status. The implications of the findings for health education are discussed.  相似文献
