Demographic Foundations of Political Empowerment in Multiminority Cities   总被引:2,自引:0,他引:2  
As U.S. cities accommodate increasing ethnic and racial diversity, political choices may unify or divide their local populations. Those choices pull communities toward two different modes of pluralism: traditional “melting pot” assimilation or a complex mosaic of racial and ethnic assertiveness. Central to this issue is equity and empowerment, which may be accentuated by minority populations’ size, structure, and spatial concentration. We examine two potential modes of local empowerment: “dominance,” whereby each group is the majority of voters in single election districts (reinforcing separative tendencies), and “influence,” whereby a group gains “influential minority” status in several districts (reinforcing unifying tendencies).  相似文献

This paper describes a representative, sectionalized, computer assisted strategic planning system, as developed and used by the authors. It suggests that the future direction of such programmes—with several already in use—is toward the development of approaches which combine simulation and linear programming to simultaneously address long and short-term objectives.  相似文献

Population projection techniques are used to project the size and age structure of the academic labor force. Age specific coverage data from Teachers Insurance and Annuity Association are used to proxy academic employment. Hiring, quit, retirement and death rates are calculated for 1981 and 1982. Projections of the future academic labor force are made holding these rates constant. The results show the importance of these entry and exit rates and also indicate how these rates can fluctuate from year to year.Estimates of the future demand for teachers are used to determine a target rate of growth of the academic labor force. Alternative personnel policies are incorporated into the projections. This analysis indicates that the personnel policies chosen to meet the desired labor force size have substantially different effects on the age structure of the labor force.The authors wish to acknowledge the cooperation of the Teachers Insurance and Annuity Association in providing the data used in this study and specifically Francis King for his assistance and encouragement. Helpful comments on this paper were provided by John Dutton, Ronald Schrimper, Jack Wilson, and Bryan Boulier.  相似文献
