This research assessed whether there is an impact of race-ethnicity on depressed mood among adolescents, independent of socioeconomic status, whether gender differences in depressed mood are apparent within all race-ethnicity subgroups, and whether pubertal development influences depressed mood in a similar manner within gender and race-ethnicity subgroups. A three-stage, area probability sampling frame was utilized to select adolescents, ages 12–17 years, for an in-person interview. Depressed mood was assessed by the Children's Depression Inventory. Compared to Whites, African Americans, or Asian Americans, Latinos reported more symptoms of depressed mood, a finding that was independent of socioeconomic status. Advancing puberty was associated with depressed mood only among females, but the timing of pubertal changes, relative to ones peers, was related to depressed mood among both males and females, and among Latinos.  相似文献

Bonding in parent, peer, and school domains were compared in a general sample of children and a sample of children of methadone-treated parents. Bivariate comparisons revealed that children of methadone-treated parents had lower SES, and were significantly more likely to smoke cigarettes but not more likely to drink alcohol. Several measures of attachment were significantly different between the two samples across parent, peer, and school domains. Multivariate analyses indicated that the children of methadone-treated parents were more likely to smoke, even after accounting for the effects of demographic and attachment variables. For drinking, sample membership was not found to be significant. Attachment to school decreased the odds of both smoking and drinking in both samples. Peer attachment had no effect on the odds of smoking initiation; however,loyalty to best friend did predict increased odds of drinking initiation.  相似文献

This paper re‐examines the Lardy—Donnithorne debate in the provincial context of Guangdong. The study period is from 1949 to 1992. In the first place, the adequacy of provincial capital investment is evaluated against its population and national income shares. Secondly, it examines the capital construction investment from the administrative perspective with capital construction projects classified into central, ministry‐supported and local projects. Thirdly, it looks at the relationship from the financial perspective through a breakdown of capital construction investment by sources of investment funds, that is, state appropriation, domestic loans, foreign investment and self‐raised funds and others. Fourthly, the central‐local relationship is scrutinized through the fiscal relationship between the central and Guangdong governments. Lastly, extra‐budgetary funds data, whenever available, are also analyzed. The paper finds that the centripetal and centrifugal forces in Guangdong have always been in dynamic and precarious balance both before and after the Open Policy.  相似文献

Budget redirection in Georgia state government represents a change from the expectation of continuous budget growth to an expectation that budget expansion will be accompanied by compensating budget reductions through an ongoing process of priority assessment. Its essential features are: the requirement that state agencies identify a minimum of 5 percent of their current year's budget which becomes the primary means for funding new programs and services in the coming fiscal year; and a limit, based upon revenue projections, on the amount an agency may request above the current year's budget. Like budget reforms in any era, it emanated from a combination of fiscal, managerial, and political objectives.  相似文献

Goal-Based Learning and the Future of Performance Management   总被引:1,自引:0,他引:1  
All levels of government have begun to pursue results-based reforms, which assume that managers will use performance information to make better decisions. However, reforms have neglected the insights of a large and relevant literature on organizational learning. This article revisits this literature, treating results-based reform as an organizational learning mechanism and a deliberate structural effort to induce learning. From an organizational learning perspective, most results-based reforms target narrow process improvement (single-loop learning) rather than a broad understanding of policy choices and effectiveness (double-loop learning), even though the latter is more critical for long-term organizational success. Case evidence from state governments illustrates single- and double-loop learning and the importance of two frequently neglected aspects of organizational learning: learning forums—routines where performance information is deliberately examined—and the role of organizational culture in enabling or limiting learning.  相似文献

Abstract

Can reinstatement of encoding context aid eyewitness identification? Two experiments are reported in which participants were asked to identify, from both a Blank and a Filled lineup, a target seen 1-week (Experiment 1) or 3-months (Experiment 2) earlier in a staged live interaction. Identifications were made following either a no context reinstatement (NCR), a CI-type reinstate context (CI-CR), a mental and physical (M&PCR) context reinstatement or a multiple reinstatement of context (Multi-CR) manipulation. In Experiment 1 in the Blank lineup condition, correct rejection (CR) and false identification (FID) rates did not differ between the four context manipulation conditions. However, within the different conditions only Multi-CR showed a significant difference between CR and FID. In the Filled lineup condition, neither correct identification (CID), FID, nor non-identification (NID) rates differed between context conditions. Within the four context conditions only Multi-CR produced significantly more CID than FID. However, the difference between CID and NID in this condition did not differ reliably. In Experiment 2, with the Blank lineup, while the rate of CR did not differ between the three context conditions, the rate of FID did, with Multi-CR producing reliably fewer than the other two conditions. In the Filled lineup condition, no differences between the three conditions for NID or FID were observed but a difference did appear for CID, with CI-CR producing the greatest number of hits. These variable results are discussed in terms of the need to consider other factors in explaining supposed context effects on recognition.  相似文献

Two separate frameworks have existed for the analysis of social predicaments in which businesses play a role: issues management and stakeholder management. In this paper, we argue that the chasm dividing these two literatures is artificial, and potentially obstructive to the advancement of our knowledge of the position of business in contemporary societies. The position we take in the present paper is that all social predicaments have an issues side as well as a stakeholder side and that a dual focus on both issues and stakeholders is therefore essential to understanding the evolution of these predicaments and crucial to managerial dealings with these issues. We present an integrative co-evolutionary framework, explaining the dynamics between issues and stakeholders in all consecutive stages of a predicament's evolution. The framework proposes a new way of thinking about issues and stakeholders, as such facilitates a deeper understanding of how the social environment of business is constituted, and offers new insights for the practical management of issues and stakeholders.  相似文献

In a companion paper to “Environmentalism in the USSR: The Opposition to the River Diversion Projects,” two geographers survey the current status of water transfer research after cancellation of the European and Siberian diversion projects and offer a different perspective on the debates leading to that cancellation. Implications of a demand-side approach to Centra! Asian water management problems are then assessed in light of (a) contradictory objectives of expanding irrigated hectarage and mitigating environmental deterioration in the Aral basin and (b) the problematic nature of projected water savings and costs involved in their realization.
