This study examined the growth in the number of female officers in supervisory and command positions (i.e., sergeant to bureau chief) in the New York City Police Department (NYPD) from 2000 to 2013. Time and annual percent changes in the number of male officers, the number of male officers in supervisory and command positions, and the number of female officers served as predictors. An ordinary least squares regression analysis failed to produce statistically significant results for the growth in the number of female officers in supervisory and command positions. The regression analysis also produced statistically nonsignificant results for changes in the level of disparity among male and female officers in supervisory and command positions. Over the past 13 years, female officers have made little progress in advancing to supervisory and command positions in the NYPD.  相似文献

In forensic DNA profiling use is made of the well-known technique of PCR. When the amount of DNA is high, generally unambiguous profiles can be obtained, but for low copy number DNA stochastic effects can play a major role. In order to shed light on these stochastic effects, we present a simple model for the amplification process. According to the model, three possible things can happen to an individual single DNA strand in each complete cycle: successful amplification, no amplification, or amplification with the introduction of stutter. The model is developed in mathematical terms using a recursive approach: given the numbers of chains at a given cycle, the numbers in the next can be described using a multinomial probability distribution. A full set of recursive relations is derived for the expectations and (co)variances of the number of amplicon chains with no, 1 or 2 stutters. The exact mathematical solutions of this set are given, revealing the development of the expectations and (co)variances as function of the cycle number. The equations reveal that the expected number of amplicon chains without stutter grows exponentially with the cycle number, but for the chains with stutter the relation is more complex. The relative standard deviation on the numbers of chains (coefficient of variation) is inversely proportional to the square root of the expected number of DNA strands entering the amplification. As such, for high copy number DNA the stochastic effects can be ignored, but they play an important role at low concentrations. For the allelic peak, the coefficient of variation rapidly stabilizes after a few cycles, but for the chains with stutter the decrease is more slowly. Further, the ratio of the expected intensity of the stutter peak over that of the allelic peak increases linearly with the number of cycles. Stochastic models, like the one developed in the current paper, can be important in further developing interpretation rules in a Bayesian context.  相似文献

Analysis of statistical data on forensic chemical studies carried out in the Perm Regional Bureau of Forensic Medical Expert Evaluations in 1997-2000 indicates an increased number of expert evaluations with positive results. The specific share of expert evaluations with positive results for Perm was 66.6% of the total number of evaluations. The absolute number of the detected agents in combinations with other agents increased more than 2-fold over the studied period. The number of detected agents increased 1.8 times, the rate of detection of narcotics increased sharply (6.5 times).  相似文献

Chapter 2 of the European Sourcebook attempts to show the differences as well as the common features of the prosecution services of the Council of Europe Member States. In order to do so the following five categories of statistics were collected: the total number of cases the prosecuting authority recorded as having been dealt with within a particular year; the number of cases brought before a court; the number of cases dropped; the number of cases dropped conditionally; the number of cases ended by the imposition of a sanction. The prosecution statistics of the European countries studied vary because of differences in the input structures. They are also affected by variations in output structures. These are determined by the powers that the prosecution authorities themselves possess. These variations between the prosecution systems within Europe cause significant differences in the resulting statistics and must be borne in mind when analysing the European Sourcebook data.  相似文献

Changes in the law, government regulations, socioeconomic changes, increased consumerism, the public's level of awareness—all these and other factors influence the population's demand over time for lawyers'services. This article analyzes the changes over time in the two elements that determine the demand for lawyers: the number of legal problems encountered by the population and the rate of use of lawyers in solving these problems. After showing that sequential occurrences of legal problems are not independent of each other and are age dependent, the author develops a mathematical model that explains the variability in the present number of problems encountered by different age groups. The number of problems is found to result from a relatively mild accumulation with age of legal problems, coupled with a strong increase in the number of problems from generation to generation. The analysis of individual legal problems reveals a variety of patterns from problem to problem in both the level of occurrence and the rate of use of lawyers for such problems. The author concludes that the combined effect of occurrence and utilization will operate toward a continuing increase in the demand for lawyers'services at least for the very near future.  相似文献

There is an increasing number of juveniles coming into the justice system with a variety of mental health and substance abuse concerns. While the actual number of youths with mental health disorders in the juvenile justice system has been difficult to determine, it is estimated to be substantially higher than it is for youths in the general population. In addition, researchers have estimated that a high number of these juveniles experience co‐morbid mental health disorders. The purpose of this study was to examine the number of youths who present symptoms of a mental health disorder at intake into a juvenile detention center in the Midwest. Two hundred‐four youths were assessed with the Massachusetts Youth Screening Instrument‐Second Version (MAYSI‐2; Grisso & Barnum, 2000), a mental health screening instrument. At least 68% of the youths identified symptoms of a mental health disorder at intake. Given the significant number of youths who identified symptoms of a mental health disorder at intake into detention, the need to provide mental health services for juvenile detainees should not be ignored.  相似文献

On 9 May 1987, a Soviet-made IL-62M Polish airliner, LOT Flight 5055, crashed, exploded, and burned, killing the crew and 183 passengers. A forensic science team from the Armed Forces Institute of Pathology, comprised of 6 dental officers, 3 forensic pathologists, and 3 medical photographers, worked in concert with the Polish forensic science team. The small number of antemortem records and the extreme fragmentation of the remains presented a new scenario for computer use. Typically, the Computer-Assisted Postmortem Identification (CAPMI) software is used to compare remains against an antemortem database. Results are listed by the number of tooth-to-tooth matches based on restorative or other characteristics or both. The Polish disaster confounded this approach to some degree, however, and suggested a reconsideration of the theory on which the sort is made, that is, that the cases with maximum number of matches to preexisting dental records would be the most likely identification (ID) match. A hypothesis was constructed that, if searches were accomplished for fragments with a minimum number of mismatches, the correct matches would appear higher in the rank order. Six antemortem records (that had all dental information) were sorted against one hundred and twelve postmortem fragmented records. The resulting report was reordered so that records were listed by minimum number of mismatches. There was significant improvement in rank placement for all of the records. Thus it was accepted that in the situation of highly fragmented remains a different sorting based on the number of mismatches is indicated. Programming changes to make this option available have been implemented in the new version of CAPMI.  相似文献

New directions for anti-theft policy: Reductions in stolen goods buyers   总被引:1,自引:0,他引:1  
This study explores the possibility of reducing theft in the United States through reductions in the number of persons who purchase stolen goods. Theft is conceptualized as a market-oriented offense that can be influenced by changes in consumers' willingness to make blackmarket purchases. Based upon several conservative assumptions about the number and the cost of thefts and the number of purchasers of stolen property in the United States, estimates of reductions in the former through reductions in the latter are calculated. Following these estimates, the issue of how best to accomplish a reduction in the number of persons buying stolen goods is addressed through analysis of data pertaining to individuals' decisions to buy stolen property. Key predictors of purchasing behavior are then reviewed for potential contributions to the inhibition of that behavior. In the final analysis, only one predictor, moral belief, appears to possess practical policy implications.  相似文献

This paper re-examines some of the current theoretical models and paradigms of criminal justice in England and Wales based on an analysis of national arrest statistics between 1981 and 1997. The data show that there has been a large increase in the number of arrests in the period but the number of people prosecuted has declined. An increasing number of people are being arrested and released without any further action. The principal argument is that there has been a radical shift in power away from the formal open and public system of justice towards a more informal closed system. The paper concludes that while these trends lend support to a number of theoretical perspectives on the criminal justice process, particularly Choongh's social disciplinary model, the radical transformation which has taken place in the form of criminal justice can only be understood within the broader politics and economic structures of modern Britain.  相似文献

This article examines types of tax registers that provide a picture of families in the Aegean Islands during the Ottoman occupation. Numerical data from the islands of Andros, Myconos, Syros, Serifos, and Patmos are emphasized. Accounts by travelers and Roman Catholic priests and other documentation of that time are also examined. The article attempts to verify the reliability of data from the registers regarding family size, number of households, the possibility of household sharing by more than one family, and number of household heads. Records of personal taxes (ispence, or poll tax) indicate that the families on the islands during the 17th and 18th centuries had only a few members. Exact data cannot be derived because the communities attempted to redistribute taxes according to their own needs rather than following official Ottoman orders. Similar indirect information is derived from another kind of register that recorded the transfer of taxpayers' properties. The number of houses for some islands seems to have steadily increased although the number of family shares did not. This phenomenon may be linked to the status of ownership of immovable property, the horizontal property that was applied, and the nonexistence of cohabitation of extended families. Another issue concerns the number of widows in the tax registers. This large number does not correspond to the family status of these women but rather to tax practices exercised by the communities and participation of these women in the economic and social life of the islands.  相似文献

The incidence of drug and chemical related deaths was studied over a six-year period in the State of Maryland. Deaths were classified into the following categories: alcohol, carbon monoxide (CO), single drugs, multiple drugs, and narcotism. The last three categories were further subdivided as to the specific drugs or chemicals involved. Over the six-year period the number of alcohol and CO deaths remained steady, the number of barbiturate and propoxyphene deaths declined, while the number of tricyclic antidepressant drug deaths increased.  相似文献

The number of forensic autopsies in cases with violent and spontaneous deaths increases from 1984 to 1996 by 11.1 and 25.8%, respectively. The rate of increase in the incidence of violent deaths outstripped 1.6 times the total mortality values. This resulted in an essential increase in the work loading of experts, with an increase in the number of complex expert evaluations. The system of registration of violent deaths is imperfect: it does not provide accurate data on the number of murders and suicides, which are overrated at regional statistical departments in comparison with the records of legal organs, while the values recorded at statistical departments are notably underrated in comparison with forensic medical records. The authors offer amendments and revisions for the current form of medical certificate of death and the order of its filling, granting, and storage.  相似文献

A comprehensive list of innovations in the semiconductor industry during 1970 to 1980 was derived. The patterns of innovation across eight organizations showed consistency between the stages of initiation, adoption and implementation. Smaller organizations compared to large implemented a lower percentage of the innovations they initiated. The value of organization net sales and the dollar amount of the R&D budget, but not the number of organization of R&D personnel were significantly related to the number of innovations.  相似文献

How does government composition affect government spending in Africa’s democracies? Many scholars have examined the political, institutional, and ideological determinants of government spending, finding that government attributes can affect government spending levels. However, many of these studies have focused on OECD countries, largely overlooking the link between government spending and government composition in African democracies. I examine support for two existing theories about the characteristics of governments that can lead to increases in spending levels: the number of parties in government and the number of ministers. I assess empirical evidence for these theories using original data on government composition in 19 African countries from 1990 to 2015 and data on government spending from the World Bank. I find that a coalition at the time the budget is passed is associated with increased spending, but the number of cabinet ministers does not appear to systematically affect levels of government spending.  相似文献

2016 coroner's crematorial inquests of the Bonn Institute of Legal Medicine over a 3 years' period were evaluated and the statements in the death certificates were compared to those ones of the Statistical Country Office of Northrhine-Westphalia. No significant differences were found with respect to age, gender and reason of death. However, the number of insufficiently classified deaths with respect to the reason of death were overrepresented especially in cases of older women, while the number of unnatural deaths was generally underrepresented. According to legal medical criteria 2 1/4 per cent of the deaths were falsely classified as natural. Only in 2 cases an autopsy was accomplished. Other author's statements on the validity of death certificates were confirmed.  相似文献

目的探讨即早基因c-jun和胶质纤维酸性蛋白(GFAP)在弥漫性脑损伤(DBI)中的表达规律。方法采用Marmarou方法制作大鼠DBI模型,将65只SD大鼠随机分为DBI组及对照组。用免疫组织化学技术(SABC)及图像分析方法观察大鼠DBI后15min、30min、1h、3h、6h、12h、24h、2d、3d、4d、6d脑组织内c-jun和GFAP表达规律,所得数据经SPSS10.0统计软件处理。结果对照组大鼠脑组织内未见c-jun阳性表达,可见少量GFAP表达。DBI15min即可在脑组织内观察到c-jun表达,而GFAP蛋白的表达则在DBI后6h增加。随着损伤经过时问的延长,c-jun与GFAP阳性细胞数及阳性表达范围逐渐扩大,c-jun表达在DBI后6h达高峰(P〈0.01),其后逐渐下降,伤后2d减退;GFAP阳性产物则在伤后4d左右达高峰(P〈0.01),其后呈下降的趋势。结论应用免疫组织化学方法检测c-jun与GFAP可作为诊断DBI的参考指标,二者在不同时段内表达所呈现出的时序性规律对损伤时间的推测也具有实际应用价值。  相似文献
