Although municipal jails consume a significant amount of resources and the number of inmates housed in such facilities exploded in the 1990s, the literature on forecasting jail populations is sparse. Jail administrators have available discussions on jail crowding and its causes, but do not have ready access to applications of forecasting techniques or practical demonstrations of a jail inmate population forecast. This article argues that the underlying reason for this deficiency is the inherent unpredictability of local long-term correctional population levels. The driving forces behind correctional bed need render local jail population forecasts empirically valid only for a brief time frame. These inherent difficulties include the volatile nature of jail populations and their greater sensitivity when compared with prison populations to local conditions; the gap between the data needed for local correctional population forecasting and what is realistically available to forecasters; the lack of reliable lead variables for long-term local correctional population forecasts; the clash of the mathematics of forecasting and the substantive issues involved in the interpretation of forecast models; and the significant political and policy impacts of forecasts on local criminal justice systems and subsequent correctional population trends.The differences between the accuracy of short-term versus long-term jail bed need forecasts means that forecasting local correctional bed need is empirically valid for, at best, one to two years. As the temporal cast is extended, longer-term forecasts quickly become error prone. Except for unique situations where jails exist in highly stable local political, social, and criminal justice environments, long-term forecasts of two years or greater are fatally flawed and have little empirical accuracy. Long-term forecasts of local jail bed needs are useful, though, as policy catalysts to encourage policymakers to consider possible long-term impacts of current decisions, but forecasts should be thought of and presented as one possible future scenario rather than a likely reality. Utilizing a demonstration of a local jail forecast based upon two common empirical forecasting approaches, ARIMA and autoregression, this article presents a case study of the inherent difficulties in the long-term forecasting of local jail bed need.  相似文献

In this article, the statistical technique for setting up the consensus of perceived crime seriousness in previous studies is critically reviewed. The conventional method, when applied to a data set of crime seriousness, is found to have exaggerated the consensus because, by using a more appropriate model, which assumes perfect agreement in crime severity between subgroups, the consensus is reduced unanimously. By breaking down the population by gender, age, and educational level, sociodemographic differentials in crime seriousness are set up. The disparity is then further examined in details by paired comparisons between a target crime with fourteen other crimes. The three factors are all found to be important in affecting perceived crime seriousness. This conclusion is different from that of previous studies. The scaling method is found to be responsible for the difference. As the Thurstone method used in this study is more responsive and can produce more discriminating results, it is recommended for future research in crime severity. Finally, the implications of the findings on some important issues, like the appropriateness of legal penalty and the construction of a crime index, are discussed.  相似文献

The article investigates the relationship between cultural similarities and differences on the part of the representatives of contending states and mediators, and outcomes of mediation efforts in militarized disputes. A distinction is made between social culture, defined primarily in terms of religious identity, and political culture, defined according to the state's political system. Analysis of 752 mediation attempts in militarized disputes occurring between 1945 and 1995 yields support for the hypothesis that mediation is more likely to succeed when the parties are from similar social cultures. The results, however, suggest that the relationship is more complex than that suggested by a simple categorization of states based on Huntington's "clash of civilizations" thesis. We also find that mediation is more likely to succeed when the parties share democratic political cultures, a finding that is consistent with the cultural/normative explanation for the democratic peace.  相似文献

Latent fingerprint deposits on thermal paper have been visualized noninvasively at visible wavelengths when illuminated with a UV‐A light source (peak 365 nm). A higher intensity UV source (250 W/m2 at 0.38 m) gave superior fingerprint visibility when compared with a 60 W/m2 (at 0.4 m) source. Removing the visible (blue) component of the light source emission did not adversely affect the visibility of the fingerprint. Sample fingerprints from 100 donors, when examined 24 h after deposition, produced identifiable fingerprints from nearly 34% of fingerprint deposits. A mechanism for the observed visibility is proposed based on low emission of visible wavelengths from areas of thermal paper coincident with the fingerprint deposit, when illuminated with UV. This is likely due to a weak color change in the thermal paper dye arising from protonated amino acid components of the sweat. This effect was not observed on nonthermal paper.  相似文献

Latent fingerprint deposits on thermal paper sourced from the U.S., China, the U.K., and Australia have been visualized by heating. U.S. and Chinese sourced paper produced two distinct types of fingerprint development. In one type (type 1), the paper dye colors where the deposit is present (as previously reported) and in the other type (type 2) the ‘inverse’ of this gives paper coloring only in areas not coincident with the deposit. Both development types gave identifiable fingerprints, the majority fading within 24 h of heating. Fingerprint development from U.K. and Australian sourced paper was exclusively type 1 and resistant to fading. Temperatures for fingerprint visualization were higher for U.S. paper (64–71°C) and Chinese paper (75–95°C) than for U.K. and Australian sourced paper (43–50°C). Particularly for Chinese sourced paper, these temperatures were within a few degrees of the normal paper color temperature. A mechanism for type 2 fingerprint development is proposed.  相似文献

Political marketing advances by engaging with new and advanced concepts from both of its parent disciplines. One of the most recent fields of brand research—the study of the human brand—is taken into the political marketing arena in this essay. Human branding is an emergent topic in mainstream marketing. The value as a brand of a person who is well-known and subject to explicit marketing communications efforts is being investigated in many fields. The concept has clear prima facie value in political marketing, where the role of a political leader as part of the political marketing offer has been recognized extensively. Politics is also a unique context given the relationship between leaders and parties, each of which has some unique brand associations. The process of exploring the application of human branding in politics also provides a context in which some of the interactions among party and leader, human brand, and organizational brand can be explored and further developed. Among the conclusions are that political party leaders require brand authenticity as an advocate of the party policy platform and brand authority to command the organization and deliver on the policies being advocated. Implications for party and campaign management are outlined.  相似文献
