The need for improved long-run projections of prison populations has increased in recent years because of record-high numbers of inmates and severe overcrowding in state and federal prisons, and because of the growing importance of changing demographic factors in influencing corrections populations. A model is developed for projecting: general population demographics; demographic- and offense-specific arrest rates, imprisonment probabilities, and times served; and then the size and composition of prison populations. Model parameters are estimated for Pennsylvania and are shown to be sensitive to demographic factors, particularly age and race. Projections of future arrests, prison commitments, and prison population are developed for Pennsylvania using projections of demographic changes in the state's population. Arrests are expected to peak in 1980, prison commitments are expected to peak in 1985, and prison populations are expected to peak in 1990, with the subsequent declines reflecting the maturation of the postwar baby boom children out of the highly crime-prone ages and, somewhat later, out of the highly prison-prone ages. 相似文献

This rejoinder to Professor Cohen's Comment is intended to elaborate on approaches we utilized in our original paper. Some of our specification was necessitated by data availability (e.g., the specification of the sanction process). We attempt to clarify our approach in regard to the intervention process. We provide an explanation of the modeling that could underly a test of the hypothesis that the control effect is a product of the arrest process—a test that we had regarded as informative but peripheral to our main points. As noted, a significant part of that test utilizes the full range of control variables available to us. Finally, we enumerate what we felt to be the main points of our paper—points we are afraid might otherwise be lost in this discussion of methodology. 相似文献

Abstract The literature on urban sprawl confuses causes, consequences, and conditions. This article presents a conceptual definition of sprawl based on eight distinct dimensions of land use patterns: density, continuity, concentration, clustering, centrality, nuclearity mixed uses, and proximity. Sprawl is defined as a condition of land use that is represented by low values on one or more of these dimensions. Each dimension is operationally defined and tested in 13 urbanized areas. Results for six dimensions are reported for each area, and an initial comparison of the extent of sprawl in the 13 areas is provided. The test confirms the utility of the approach and suggests that a clearer conceptual and operational definition can facilitate research on the causes and consequences of sprawl. 相似文献

This article evaluates the Vaso de Leche (VL) feeding programme in Peru in order to illustrate an evaluation methodology based on targeting criteria for a decentralised transfer programme. We find that the degree of overall targeting of poor individuals attributable to the central government's choice of districts is greater than that attributable to choice of participants within districts made by the municipalities and the mothers' committees. However, when we use a version of a targeting efficiency measure first introduced by Galasso and Ravallion [2003] which we modify to be defined on the values of allocations, the opposite is the case. The community-based decision makers appear to be targeting the poor in terms of the values of the transfers. 相似文献
