Based on findings from the 1970s, research literature on senior government executives emphasized a growing integration of politics and administration. This integration was reflected in what we called the "Image IV" bureaucrat wherein political role traits combined with those of traditional bureaucratic ones. Although this was by no means a dominant trend, we were led to speculate that traditional divisions between political and bureaucratic roles were eroding. Data gathered from the 1980s and 1990s, however, lead us to infer that divisions between political and bureaucratic roles have reasserted themselves and that integration between them is being diminished rather than strengthened. We conclude that this may be because in an era of governmental austerity the demand for executive policy entrepreneurs has slackened while the political needs have shifted to those of managerial control over an inertial or even contracting state.  相似文献

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.

The relationship of residential setting (living with parents vs. living away from home while attending college) and gender with late adolescents' perceptions of their relationships with parents was examined. Four hundred four undergraduates students (mean age=20 years, 4 months) from two midwestern universities completed surveys. Two hundred four subjects lived with their parents and commuted to school, and 200 lived away at college. Controlling for student's age, parents' education, and financial and family considerations as factors in the choice of a college, living away was associated with greater independence, support, and mutual respect between parents and adolescents. In contrast, students who lived at home felt parents underestimated their maturity, and reported more conflict and avoidance in their relationships with parents. Regardless of residential setting, women reported more mutuality and support in their relationships with parents than men. The results suggest the importance of considering contextual issues during the transition to adulthood.This research was supported by a Campus Grant to the first author from the University of Michigan-Dearborn.Received Ph.D. in developmental psychology from the University of Michigan.

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

Abstract: This paper compares and contrasts the application of competitive tendering policies in the public and private sectors. It is based on information derived from a large-scale survey of public and private sector organisations in New South Wales. Analysis of the survey responses suggests a common approach to the basic elements of the tendering (market-testing) process. However, there are also some important differences, the most striking of which is that public sector organisations advertise more frequently and generally review more tenders. Despite this, there appears to be little difference in the degree of effective competition achieved between the two sectors. More generally, while nearly all organisations surveyed collect information that is relevant to performance evaluation, it does not appear to be systematic or rigorous enough to secure contract compliance.  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

One hundred ninety-four hospitalized adolescents were administered the Adolescent Depressive Experiences Questionnaire (DEQ-A). The DEQ-A factors (dependency, self-criticism) correlated well with independent measures of depression, hopelessness, self-esteem, and suicide risk. After controlling for depression, self-criticism and dependency showed differential associations with hopelessness, violence potential, and impulsivity. A subgroup of 84 inpatients identified as either highly self-critical or highly dependent based on the DEQ-A was also compared for differences in personality and symptomatic behavior. Self-critical and dependent patients exhibited equally high levels of depression, hopelessness, suicidality, and low self-esteem. Few differences were observed in personality or symptomatic behavior between the two groups. These findings, while extending previous research that relied on community samples of young adults, provide only mixed support for a distinction between these two categories of depression.  相似文献
