The study of comparative government is in a state of relatively limited development. Questions are still being raised about the specificity of the subject matter and of the methodology; the enthusiasm with which comparative political scientists went into grand models in the 1960s and early 1970s has been followed by a degree of scepticism This scepticism is not justified It was imprudent to move so quickly towards grand models, while what was critical for the development of comparative government was and continues to be twofold First, there has to be a substantial improvement in our knowledge of political life all over the world: this has begun to occur, but empirical studies must be pursued more systematically and in a true comparative manner Second, the major theoretical thrust has to relate to the understanding of structures, which arc the key elements in the life of political systems; this means in particular that we have to understand systematically and dynamically such questions as institutionalization, integration, legitimacy, as well as the relationship between values and structures. If this were to occur, as it can and if empirical studies develop at a rapid pace in parallel, there is no reason to be despondent about the future of comparative government. 相似文献

In this study, we focused on the academic attainment of African American adolescents as they made the transition from pregnancy or recent delivery to 2 years postpartum. We examined the duration, characteristics, and effects of relationships that endured over 2 years postpartum, and the role of adolescents' mentor versus maternal support. Compared to participants who did not identify mentors at either time point, participants whose mentor relationships endured over the course of the 2-year study were more likely to have remained in school or graduated. Subsequent analyses revealed that long-term mentor relationships were characterized by weekly and, in many instances, daily interactions. Additionally, participants in long-term mentor relationships reported deriving more emotional support from their mentors than from their mothers, were more satisfied with mentor support, and indicated that this support was more important to them than maternal support. 相似文献

Environmental policy encouraging hazardous waste reduction began in 1976 with an Environmental Protection Agency statement promoting source reduction as the preferred method of hazardous waste management. In 1984, Congress included a policy statement supporting waste reduction in the Hazardous and Solid Waste Amendments (HSWA). However, the cornerstone of HSWA was the land disposal restrictions (LDRs)—a command and control policy prohibiting land disposal of untreated hazardous waste. Consideration of the hazardous waste generation decision in the aggregate would suggest that the price effect resulting from the LDR program and increased hazardous waste management prices in general would lead to source reduction. Although at the firm level there may be interdicting factors, statistical analysis of generation data for Tennessee support this hypothesis. Both the institution of the LDRs and waste management prices have significant negative effects on the level of generation. The analysis, however, reveals the existence of large industry and firm effects, indicating that the response to public policy may exhibit significant variance, especially at the individual generator level. 相似文献
