Self-esteem and psychological symptoms were assessed in a sample of 1082 Chinese adolescents who responded to the Chinese versions of Coopersmith's Self-Esteem Inventory and the General Health Questionnaire. Three dimensions of self-esteem, interpreted as Family Acceptance/Rejection, Self-Depreciation, and Peer Affirmation/Disaffirmation, were found to relate substantially to general psychological symptoms and particularly to specific symptoms of anxiety, social dysfunction, and depression as reported by these adolescents. The implications of the relative importance of appraisal from internal feedback as sources of self-esteem as opposed to the external feedback from family and peers were discussed in relation to self-esteem enhancement in adolescents.Received his Ph.D. from the University of Western Ontario in 1978.

Abstract. Estimates of voting by occupational class are provided for each of 22 regions in the UK for every general election since 1964. These are analysed, using a log-linear modelling strategy, to identify the changing degree of class dealignment and spatial polarisation within the British electorate over the period. The growing regional variability is consistent with expectations regarding the increasing volume of economic voting and the pattern of uneven development in the country: the north-south and urban-rural divides have both widened. 相似文献

Philip G. Joyce 《Public Budgeting & Finance》1993,13(4):3-17
The political system, the popular press, and the public have recently been concerned about measuring government performance. This concern for measuring performance should imply a concern for measuring it correctly. With this in mind, the Congressional Budget Office (CBO) recently conducted an analysis of the use of performance measures in the budget process. The study attempts to review the issues raised by performance budgeting in the context of past and current efforts to link performance measures and budgeting. This article focuses on two portions of that study: The status of the current federal performance measurement efforts and specific observations designed to inject a note of caution into the current debate about performance measurement and budgeting. 相似文献

In this paper a new economic approach to standardization has been presented. Standardization has been regarded as a problem ofgradual choice. An individual chooses to apply more or less standards within a hierarchy of standards. With this decomposition of standards, the problem of strategic market power becomes less important than in the traditional models of standardization. It becomes possible to analyze the problems of network externalities within a framework of non-strategic behavior and to apply the tools of the traditional theory of externalities and public goods. While decentralized action may lead to too little standardization, committees may overcome this deficiency to some extent, but bureaucracies are likely to lead to overstandardization. In the empirical section of the paper it has been shown that our approach can be applied to the standard-setting process in languages, railroads, and telecommunications. In all three cases the tendency of bureaucracies to generate more standardization than committees has been corroborated.The authors are indebted for helpful comments to the participants of the Berlin Seminar on Political Economy and of the colloquium Algemene Economie, Rijksuniversiteit Groningen, and to A.

This paper presents evidence that voter participation does not depend on the probability that one vote is decisive. An extensive summary of the empirical participation literature is provided which shows that most but not all studies have found that turnout in an electoral district is higher when the race is closer. Individual-level vote regressions for the 1979 and 1980 Canadian national elections are estimated using objective measures of closeness (as opposed to self-reported measures). The main finding is that a citizen is no more likely to vote in a close election than in a lands-lide election. District-level turnout regressions for the same elections are also estimated, and a significant relation between closeness and turnout is observed. This suggests that aggregation bias may generate a spurious closeness-turnout relation in district-level regressions. 相似文献

The progressivity and equity of both state and federal individual income taxes, as well as the combined system of both taxes, are examined before and after the federal Tax Reform Act of 1986 using a variety of measures applied to federal Statistics of Income individual income tax data; state taxes are calculated using TAXSIM. Our findings are as follows: First, in both 1985 and 1987, state personal income taxes were generally less progressive and more horizontally equitable than the federal system. Second, in moving from 1985 to 1987, state personal income tax systems generally displayed decreased progressivity and horizontal inequity. The combination of the two systems displayed generally lower progressivity and horizontal equity scores when we compare 1987 to 1985. Last, the after-tax income distribution became more unequal when we compared 1987 to 1985. 相似文献
