Generativity, defined as concern for future generations, is theorized to become a priority in midlife, preceded by a stage in which intimacy is the central issue. Recent research, however, has found evidence of generativity even in adolescence. This longitudinal study explored the associations between caregiving in friendships, closely related to intimacy, and early generative concern in a young adolescent sample. Given the importance of close friendships in adolescence, it was hypothesized that responsive caregiving in early adolescent friendships would predict later generative concern. Approximately 140 adolescents (56 % female, aged 14 at Time 1) completed questionnaires regarding generative concern and responsive caregiving with friends yearly across 2 years. Structural equation modeling revealed that caregiving predicted generative concern 1 year later but generative concern did not predict later caregiving. These results suggest that caregiving in close friendships plays an important role in the development of adolescents’ motivation to contribute to future generations. 相似文献

This article investigates the life and works of Hortense Powdermaker (1896-1970). In contradistinction to the intellectual climate of her times, Powdermaker's intellectual trajectory can be characterised as eclectic, dynamic and forward thinking. Spanning nearly four decades, Powdermaker's academic career was dedicated to developing a distinct ‘anthropological vision’. Yet, although she conducted studies of culture and society that transcended structures of orthodoxy and charted alternative theoretical and methodological terrain, in turn establishing herself as a pioneer of contemporary anthropological thought, Powdermaker's work has failed to gain incorporation into wider disciplinary research agendas. Set within a sociology-of-intellectuals framework, it is argued that Powdermaker occupies a peripheral position in the history of anthropology – a position which does not adequately reflect the significance of her work – and that Powdermaker's greatest intellectual contribution was her innovative epistemology and sophisticated ‘anthropological vision’. Nonetheless, as a result of the powerful traditions and orthodox schools of thought which reigned supreme in mid-century anthropology and sociology, she was unable to exert any enduring influence on British or American social thought. 相似文献

We investigate how aspects of "civil service" systems of personnel management interact with bureaucratic discretion to create expert bureaucracies populated by policy-motivated agents. We construct a dynamic model in which bureaucrats may invest in (relationship-specific) policy expertise and may or may not be interested in policy choices per se. The legislature makes sequentially rational grants of discretion, which serve as incentives for expertise investment and continued service only for policy-motivated bureaucrats. Bureaucratic policy preferences and the legislature's agency problem vis-à-vis bureaucracies develop endogenously in the model. Bureaucratic expertise can be supported in equilibrium only at a cost of its politicization; "neutral competence" is inconsistent with strategic incentives of bureaucrats. We identify several conditions that support the development of an expert bureaucracy in equilibrium, including security of job tenure and control over policy issues for policy-motivated bureaucrats. 相似文献

President Clinton's veto of the 1995 reconciliation bill, the largest and most ambitious such legislation ever passed by Congress, was the first time a reconciliation bill was ever rejected by a president. It was also the first reconciliation bill in two decades to include a tax reduction rather than a tax increase. The fate of this bill, and its scope and contents, suggest the need to assess the evolution of reconciliation within the congressional budget process. In the early 1980s, Congress altered budget reconciliation procedures, putting in place a powerful new capability for deficit reduction. Reconciliation became the primary means within the budget process of restraining entitlement spending and increasing taxes as part of congressional efforts to reduce the deficit. Gramm-Rudman-Hollings magnified certain problems Congress encountered in using reconciliation to control entitlements, producing increased pressure to cut discretionary spending. While the Budget Enforcement Act of 1990 included new authority to use reconciliation to restrain entitlements, congressional spending priorities combined with the Peace Dividend to maintain the relative sanctuary entitlement programs have enjoyed. The limits of reconciliation as a deficit reduction tool, both in terms of increasing revenues and curtailing entitlements, are detailed. The inherent procedural advantages accorded to entitlements are contrasted with the treatment of discretionary programs, explaining in part the widening gulf between these two categories of spending. Congress has attempted, without success, to find alternatives to reconciliation. The failure of the seven-year, deficit-eliminating reconciliation bill of 1995 may indicate that certain Limits on the use of reconciliation may have been reached. 相似文献

The immediate effect of the Budget Enforcement Act (BEA) of 1990 was to cancel a pending $110 billion sequester and to change the Gramm-Rudman-Hollings deficit targets. These and other changes allowed Congress and the administration to escape responsibility for increases in the deficit if discretionary spending was kept within the caps and no new entitlement programs or revenue enhancements were added. This assumption and others relating to the empowerment of the Appropriations Committees and the new authority of the OMB are explored in this article. 相似文献

Mandibular ramus height as an indicator of human infant age 总被引:1,自引:0,他引:1
Norris SP 《Journal of forensic sciences》2002,47(1):8-11
There were two goals to be achieved from the analysis of 53 skeletonized infants from the Southwest Collection at the National Museum of Natural History. The first objective was to determine whether this infant sample could be aged based on a mandibular measurement. The second was to determine which dimension of the mandible, if any, most accurately predicts infant age within a six-month range. Seven osteometric measurements were applied to each mandible. Statistical analysis determined that the individuals in the Smithsonian's Southwest Collection that were under two-years-old could be accurately aged to within six months. Out of these seven measurements the most accurate age-at-death estimates were generated based on the maximum height of the mandibular ramus. This finding can potentially aid investigators in determining the age-at-death of infants. 相似文献
