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

This article explores the theoretical and empirical issues in unit root nonstationarity for multiproduct acreage response systems. A wheat/barley acreage response system for the praire provinces region of Canada is estimated and the existence of a unit root cannot be rejected empirically. It is shown that while the estimates of this system are very similar whether or not a unit root is assumed, the effects of a one-shot policy shock in the two alternative models are very different. 相似文献

Based on attachment theory and research, Family Attachment Narrative Therapy is introduced as a new family therapy modality developed to heal the experience of early childhood maltreatment. Unresolved childhood trauma has been correlated with impaired and delayed cognitive, behavioral and emotional functioning. Gentle, soothing, nonprovocative and nonintrusive narratives told by parents provide an alternative restorative experience designed to shift and change the child's destructive internal working model. The result is improved functioning and the ability to accept nurturing and care in relationships that offer love and safety. A representative case example is used to illustrate theory, practice and outcome. Pre- and posttherapy assessment supports the claim of improved functioning. 相似文献
