This paper explores how administrative organization practices mediate the impact of equal employment opportunity policy. Extra organizational variables are discussed as factors influencing the significance of organizational action. Organizational action in EEO may be rooted in a theory of change which views people as the critical variables or in a theory of change which views organizational structures or processes as critical. Intervention strategies flowing from each assumption are catalogued and special issues raised in exploring the impact of alternative strategies are discussed. 相似文献

ABSTRACT. Intervention analysis is used to assess the impact of the October 1987 stock market crash upon employment in the securities industry in New York City. The results indicate that the crash has led to a gradual, but permanent reduction of approximately 25,000 jobs in this industry through July 1990. Using a dynamic location quotient methodology to measure basic employment, an estimate of a partial-adjustment economic base multiplier suggests that total New York City employment is likely to decline by over 100,000 as a result of the crash and subsequent adjustments in the securities industry. 相似文献

Basically, we have attempted to show the following in the course of setting out the algebra of regression analysis of selected regional employment multiplier models: (1) When the basic features of the model are shaped by the assumption of an unlagged response of local employment to changes in export employment, the least squares estimates of the multipliers are highly sensitive to the export coefficients vector A, given the sample observation matrix X. In a completely disaggregated model such as Equation (21), the multipliers are solely determined by the export coefficients and thus are entirely independent of sample observations. However, this independence does not hold in the case of a partially disaggregated model. The identity relation is also destroyed when a lag relationship is introduced into a completely disaggregated model. (2) A simple lag model produces results bascially different from those obtained by an unlagged model if the overall differences between current and lagged observations are significant. (3) Given a matrix of sample observations on employment, it is possible to estimate the upper limits of a least-squares aggregate multiplier and its variance simply from knowledge of the export coefficients (4) The export coefficients vector has also an important bearing upon the correlation coefficient. The correlation is unity if and only if the export coefficients vector is proportional to the local employment coefficients vector, while it is zero if and only if the export coefficients vector is a vector all of whose elements are one. Also, the correlation coefficient is equal to one when a completely disaggregated model is used. There is finally the question of what these results mean in terms of the formulation of a multiplier model. First of all, in view of the crucial importance of the export coefficients and the difficulties of estimating them, most of the existing models do not seem to offer promising results. Furthermore, all the models examined here have made some simplifying assumption with respect to the constancy of the export coefficients. It remains highly uncertain whether these coefficients are reasonably stable over time. Of course, it would be theoretically more acceptable to relax the assumption of the invariance of export coefficients and to obtain such coefficients at different points of time for each industry. However, this would be accomplished only at the cost of increased difficulties of estimating larger numbers of export coefficients. In addition, there is some doubt as to the validity of the assumption that export employment is proportional to export sales. Since a lag relationship is important not only in terms of attempts to formulate multiplier models more realistically, but also in terms of its significant effect on the multiplier values obtained, the nature and the form of a lagged response and its estimation problems need to be investigated in depth. Finally, problems of least squares bias and efficiency, inference, and prediction which may arise in the context of various models presented here remain to be investigated. A detailed analysis of such problems must be the subject of further investigation. 相似文献

The application of phosphorus analysis to archaeological contexts can be considerably improved through ultrasonic extraction and the statistical evaluation of results through an analysis of variance. Such tools make the archaeological application of phosphorus analysis faster as well as more economical and coherent. This paper describes the features of these tools and provides a practical case: the Late Neolithic—Early Copper phase of the site ‘Polideportivo’in Martos, southern Spain. 相似文献

The article reports research on informed opinion as to linkage between Bakke and the discretionary use of race in private employment practice. Of particular concern is the legal parallel between the 1964 Civil Rights Act, Title 6 as applied in Bakke and Title 7 as it relates to Kaiser Aluminum v. Weber and to other employment cases. The principal research entailed Q-methodology, a technique allowing respondents to produce and present a structured attitude (mind set) with regard to an issue or controversy. Focus of the study was upon 1) respondent values or norms as to race in employment; 2) opinions as to the impact of Bakke upon race in employment; and 3) perceptions of Bakke as portent of things to come. Responses were made in the Fall of 1978. Respondents were from groups indicating interest in Bakke, together with university teachers in relevant fields. Factor analysis of responses revealed three principal attitudes. One attitude (Factor I) strongly affirms race-conscious affirmative action, including quotas, sharply condemned the Supreme Court for abrogating (in Bakke) its responsibility for protecting minority rights, and saw Bakke as a portent of unwelcome things. Factor II condemns any consideration of race in programs of admission or employment, predicted some beneficial legacy of Bakke, but was most critical of its deference to racial considerations. Factor III is pragmatic and was supportive of the Supreme Court Bakke decision, from which it projected beneficial consequences. Factor III accepts the discretionary use of race while rejecting quotas. Survey research conducted by others reveals that a public majority holds opinions most congruent with Factor III. In the employment area specifically, a majority rejects quotas but endorses minority training programs. The 1979 Weber decision gives a limited sanction to voluntary quotas, but does not exceed the range of tolerance set by a public permissive in this particular policy area. 相似文献

Innovation in judicial administration has proceeded slowly for many reasons. The attitudes of judges not-inclined by training toward management, the tradition of Judicial independence, and the separation of powers are examined as contributing factors inhibiting judicial modernization. Federal Judicial reform has defended historically upon the leadership of a Chief Justine of the United State? willing to use the office to dramatize and promote the issues. The most recent period of dramatic change in judicial administration, from 1969-1981, is reviewed with a focus upon the strategies for change employed by Chief Justice Warren E, Burger. 相似文献

会展经济是市场经济的产物,大力发展会展经济,对推动社会经济起着巨大的作用.会展与现代经济的密切关联决定了会展人才的培养要适应会展市场对人才的需求.因此,培养会展市场需要的高素质人才是高等院校教育工作者亟待解决的问题.课程结构体系是实现人才培养目标、提高人才培养质量的核心所在.而国内高等院校会展课程设置缺乏体系,造成泛而杂、全而乱等问题,影响了人才培养目标的实现.本文对美国乔治·华盛顿大学会展管理专业和英国利兹城市大学会展专业的课程体系进行了细致的分析,旨在为新办会展经济与管理专业院校的课程体系及人才培养提供可借鉴的发展思路. 相似文献

Summary. This study examines the provenance of rock types used in the construction of Middle Neolithic passage grave stones on the islands of Guernsey and Jersey, focusing on the social dimensions of stone selection. The use of stones in passage grave construction includes both local and non-local rock types, which at some sites are organized in distinctive patterns. It is argued that the choice of stones was bound by concepts of identity, and that the communities which gathered to build these monuments may have used specific rock types to represent their community and their local mythologies. The relationship between identity and stone selection is supported both by analogy and by research into the role of landmarks in the development of local landscapes and ideology. The success of megalith provenance studies on Guernsey and Jersey suggests considerable potential for future research in other geologically diverse regions. 相似文献
