Negative physical and verbal interactions occurring between early adolescents and their closest-spaced sibling were examined. Two hundred forty-four junior high school students provided information concerning their experiences as victims and perpetrators of aggressive and agonistic behaviors. Results confirm earlier studies' findings that siblings engage in numerous hostile interactions and that females and males perform these behaviors to an almost equal extent. Participants' self-reports suggest that parents may underestimate sibling use of physical force to resolve conflicts. Findings indicate there is further need to examine sibling interactions in order to better understand family functioning and family violence.  相似文献

Conclusion The issue of justice in intergenerational exchange has been studied with a focus on what is owed the elderly. Conceptual matters have been emphasized. The analysis has concerned two levels: the macrolevel on which a social contract might be achieved between representatives of generation-based interest groups, and a microlevel on which members of families and family-based networks have to find a proper balance between elder care and their other wants and obligations. The paper was written with the situation in Sweden in mind, but I believe that the analytical arguments have a wider generality.  相似文献

This article considers the way in which the Federal Court of Australia has adapted to the native title jurisdiction. Here we see how common law approaches to law and procedure challenge, and are challenged by, the culture of indigenous peoples and customary law. It conveys the risk of cultural violence in a balancing of legal and cultural norms and shows how access to justice debates reach beyond debates about funding and advice into more fundamental issues about legal process and the nature of substantive law. The Court's approach to facilitating access to justice goes deeper than essential procedural changes. Its approach suggests a cultural change within the Court.  相似文献

The withdrawl of Federal funds in a number of social service programs and state and local government budgets calls for an upsurge in volunteerism. Since August 1978, a Technical Volunteer Service (TVS) has been doing just that at one of the nation’s largest Federal laboratories. As measured by service to the community, acceptance by laboratory management, and satisfaction for the volunteers, this program has been an outstanding success. The time is ripe to transfer this program to other Federal laboratories, universities and industry. This paper describes the program and offers practical suggestions for its transfer to other organizations.  相似文献

Agricultural marketing orders, put into operation with the initiative and approval of affected producers, are a form of supervised self-regulation. The 47 orders in effect variously authorize quantity controls, quality controls, and market support activities for fruits, vegetables, and specialty crops. Administered by producer committees under the supervision of the Agricultural Marketing Service, for most of their history they produced l i t t l e controversy. In recent years they have been attacked as anticompetitive. The impact of orders on prices, however, seems limited at best. Orderly marketing has largely replaced concern for "parity prices" as the goal of marketing orders.  相似文献

Anderson reviews the notion of the “captured” regulatory agency and summarizes four theories for how it occurs. The author then uses the example of the newly formed Texas Public Utility Commission to demonstrate none of the four apply; that the regulators became “enraptured” with the interests of the industry rather than “captured” by them.  相似文献

The Dasht‐e‐Kawir in central Iran is a catchment, which includes saline, swampy areas and sandy land.

The system of water supply in the margins of the Dasht‐e‐Kawir is limited by the amount of underground water which can be extracted by qanats and wells.

Six kinds of qanats and two kinds of shallow wells have been recognized in the region.

A qanat is usually produced in six stages, of which measurement of the gradient is the most crucial for its successful construction. Thus, the construction of thirty qanats in the margin of Dasht‐e‐Kawir has been studied to determine the logical relationship between (a) the gradient, (b) the depth of main well, (c) the length and (d) the discharge of the qanat.  相似文献
