Explaining the Extraordinary Decline in Chicago’s Homicide Arrest Rates, 1965 to 1994 and Beyond: Trends in Case Mix Versus Standards for Arrest 芝加哥杀人案逮捕率异常下降的原因,1965 年至 1994 年及其后:案件组合趋势与逮捕标准

Chicago’s homicide arrest rate dropped from 91% in 1965 to 57% in 1994 and dropped still lower in recent years. This pattern mirrors the trend in the national homicide clearance rate. A plausible explanation for this great decline is the trend in homicide case mix, which arguably has made it intrinsically more difficult to solve homicide cases. Our analysis describes the change in case mix for the period 1965 to 2020 and analyzes the effect on the arrest rate for the first 30 years of this period, all by use of a unique homicide case microdata set. We document the large changes in case mix: for example, the percentage of all homicides in which a male victim was shot outdoors increased from 18% (1965) to 69% (2020). But the change in case mix does not account for Chicago’s great decline during the earlier decades, as we demonstrate by use of a novel arrest rate index. In fact, the arrest rates in each of the categories defined by location, sex, and weapon type exhibited similar declines through 1994. (Subsequent years of arrest data are unavailable for now.) Our preferred explanation for the great decline is that the operational standard for making an arrest increased during this period. That interpretation is well supported by evidence explaining the corresponding national trend, though direct evidence is lacking for Chicago. This interpretation challenges the use of the arrest rate as a police performance indicator and offers a positive interpretation of the great decline.
芝加哥的凶杀案逮捕率从 1965 年的 91% 降至 1994 年的 57%,近年来下降幅度更大。这一模式反映了全国凶杀案破案率的趋势。对这一大幅下降的一个合理解释是凶杀案的案件组合趋势,这可以说从本质上增加了破获凶杀案的难度。我们的分析描述了 1965 年至 2020 年期间案件组合的变化,并分析了这一时期前 30 年对逮捕率的影响,所有这些都是通过使用独特的杀人案件微观数据集来实现的。我们记录了案件组合的巨大变化:例如,在所有凶杀案中,男性受害者在户外遭到枪击的比例从 18%(1965 年)上升到 69%(2020 年)。但是,案件组合的变化并不能解释芝加哥在前几十年的大幅下降,我们通过使用新的逮捕率指数证明了这一点。事实上,在 1994 年之前,按地点、性别和武器类型划分的各类逮捕率都呈现出类似的下降趋势。(我们更倾向于将逮捕率大幅下降的原因解释为在此期间逮捕的操作标准提高了。尽管缺乏芝加哥的直接证据,但解释全国相应趋势的证据很好地支持了这一解释。这种解释对将逮捕率作为警察绩效指标的做法提出了质疑,并为大幅下降提供了积极的解释。

Over the past two decades, the study of terrorism has been increasingly integrated into mainstream criminology. Like other types of criminal behavior, terrorism can be divided into etiology (an emphasis on “breaking laws”) and criminal justice (an emphasis on “making laws” and “reacting toward the breaking of laws”). Moreover, like the study of crime, the study of terrorism is inherently multidisciplinary. Nevertheless, terrorism differs from more common forms of crime in fundamental ways: Terrorist perpetrators, unlike common criminals, rarely see themselves as criminal, often seek rather than eschew publicity, and often have broader political goals. Despite similarities and differences, we could identify little prior research that has directly compared the determinants of terrorism and more ordinary types of crime. In this article, we create large cross-national datasets on homicides and terrorist attacks and then compare the effects of a set of common economic, political, and social variables on each. We find a good deal of similarity in the determinants of the two types of violence. Both homicide and terrorism are more common in countries with high GDP, high percent urban, high ethnic fractionalization, and in countries moving toward democratization. Both homicide and terrorism are low in countries experiencing high globalization. Although homicides are more common in countries experiencing high levels of inequality and poverty, neither of these two variables is significantly associated with terrorist attacks. We discuss the implications of the findings for theory, policy, and future research.
在过去的二十年里,对恐怖主义的研究越来越多地融入主流犯罪学。与其他类型的犯罪行为一样,恐怖主义可分为病因(强调“违法”)和刑事司法(强调“制定法律”和“对违法行为作出反应”)。此外,与犯罪研究一样,恐怖主义研究本质上是多学科的。然而,恐怖主义在根本上与更常见的犯罪形式不同:与普通罪犯不同,恐怖主义罪犯很少将自己视为罪犯,经常寻求而不是回避公众宣传,而且往往有更广泛的政治目标。尽管有相似之处和差异,但我们几乎没有发现以前的研究直接比较了恐怖主义和更普通类型犯罪的决定因素。在这篇文章中,我们创建了关于凶杀案和恐怖袭击的大型跨国数据集,然后比较了一组常见的经济、政治和社会变量对每种情况的影响。我们发现这两种暴力的决定因素有很大的相似性。凶杀和恐怖主义在GDP高、城市比例高、种族分化程度高的国家以及走向民主化的国家更为常见。在高度全球化的国家中,凶杀和恐怖主义都很低。尽管凶杀案在经历高度不平等和贫困的国家更为常见,但这两个变量都与恐怖袭击无关。我们讨论了这些发现对理论、政策和未来研究的启示。

The COVID-19 Pandemic, Prison Downsizing, and Crime Trends 新冠肺炎疫情、监狱规模缩小和犯罪趋势

California has fundamentally reformed its criminal justice system. Since 2011, the state passed several reforms which reduced its massive prison population. Importantly, this decarceration has not harmed public safety as research finds these measures had no impact on violent crime and only marginal impacts on property crime statewide. The COVID-19 pandemic furthered the state’s trend in decarceration, as California reduced prison and jail populations to slow the spread of the virus. In fact, in terms of month-to-month proportionate changes in the state correctional population, California’s efforts to reduce overcrowding as a means to limit the spread of COVID-19 reduced the correctional population more severely and abruptly than any of the state’s decarceration reforms. Although research suggests the criminal justice reforms did not threaten public safety, there is reason to suspect COVID-mitigation releases did. How are COVID-19 jail downsizing measures and crime trends related in California, if at all? We address this question in the current study. We employ a synthetic control group design to estimate the impact of jail decarceration intended to mitigate COVID-19 spread on crime in California’s 58 counties. Adapting the traditional method to account for the “fuzzy-ness” of the intervention, we utilize natural variation among counties to isolate decarceration’s impact on crime from various other shocks affecting California as a whole. Findings do not suggest a consistent relationship between COVID-19 jail decarceration and violent or property crime at the county level.
加州已经从根本上改革了其刑事司法系统。自2011年以来,该州通过了几项改革,减少了庞大的监狱人口。重要的是,这种分离并没有损害公共安全,因为研究发现,这些措施对全州范围内的暴力犯罪没有影响,对财产犯罪的影响也很小。COVID-19大流行进一步推动了该州的去隔离趋势,因为加州减少了监狱和监狱人口,以减缓病毒的传播。事实上,就州惩教人口的逐月比例变化而言,加利福尼亚州为减少过度拥挤而做出的努力,作为限制COVID-19传播的一种手段,比该州的任何解除监禁改革都更严重、更突然地减少了惩教人口。尽管研究表明,刑事司法改革并未威胁到公共安全,但有理由怀疑缓解covid - 19的释放确实威胁到了公共安全。如果有的话,加州的监狱缩减措施和犯罪趋势是如何相关的?我们在当前的研究中解决了这个问题。我们采用综合对照组设计来估计旨在减轻COVID-19在加州58个县传播的监狱隔离对犯罪的影响。采用传统方法来解释干预的“模糊性”,我们利用县之间的自然变化,将脱碳对犯罪的影响与影响整个加州的各种其他冲击分离开来。调查结果并未表明,COVID-19监狱减刑与县一级的暴力或财产犯罪之间存在一致的关系。

Victims’ willingness to report crime and their opinions about the police are important indicators of police performance, police legitimacy, and trust in the justice system. This study examines two decades of trends in police notification and victims’ perceptions of the police in the United States and major metropolitan areas since 2000, using data from the National Crime Victimization Survey (NCVS). In contrast to previous studies indicating an increase in police notification in the 1980s and 1990s, the present study shows a progressive decline in police notification observed in the last two decades, especially since 2010. Furthermore, there has been a marked increase in victims’ mistrust of police responsiveness since the mid-2000s. Using multivariable regression models that control for potential changes in the characteristics of crime and survey methodology, we find that the victims’ rising distrust of the police is widespread in many metropolitan areas, in all racial/ethnic and socioeconomic groups, and especially so for victims of theft, burglary, and simple assault. In the discussion, we suggest that the changing policing strategies and the evolving economic, political, and social environments of the 21st century may help explain the trends identified by this research. Understanding victim reporting trends and victims’ opinions of the police may affect data and policy and help the justice system to better serve victims and enhance public safety.
受害者举报犯罪的意愿及其对警察的看法是衡量警察表现、警察合法性和对司法系统信任的重要指标。这项研究利用国家犯罪受害者调查(NCVS)的数据,调查了自2000年以来美国和主要大都市地区20年来警察通知和受害者对警察的看法的趋势。与之前的研究表明,在20世纪80年代和90年代,警察通知有所增加相比,本研究显示,在过去20年中,特别是自2010年以来,警察通知逐渐减少。此外,自2000年代中期以来,受害者对警方反应的不信任明显增加。使用控制犯罪特征潜在变化的多变量回归模型和调查方法,我们发现受害者对警察日益增长的不信任在许多大都市地区、所有种族/民族和社会经济群体中都很普遍,尤其是盗窃、入室盗窃和简单袭击的受害者。在讨论中,我们建议,21世纪不断变化的警务策略和不断演变的经济、政治和社会环境可能有助于解释本研究确定的趋势。了解受害者报告趋势和受害者对警方的意见可能会影响数据和政策,并有助于司法系统更好地为受害者服务,加强公共安全。

A matrix is proposed to characterize mental health diversion programs and standardize the reporting of program context, outputs, outcomes, and community settings. Data collection for program reporting is challenging because individual programs report on what is relevant to local conditions and may omit or overlook important contextual or structural factors that are key to programmatic success or failure. This limits generalizability and comparability. Using a standard matrix reporting framework clearly lists the constructs of the program, context, and community systems. Two diversion programs are reported demonstrating the use of the matrix. Although different jurisdictions have a wide spectrum of agencies and resources available to support diversion, and may approach the concept differently, standardizing and streamlining reporting will assist with evaluation of diversion and the creation of sustainable programs.
提出了一个矩阵来表征心理健康转移计划,并标准化计划背景、产出、结果和社区环境的报告。项目报告的数据收集具有挑战性,因为个别项目报告的内容与当地情况有关,可能会忽略或忽略对项目成功或失败至关重要的重要背景或结构因素。这限制了可推广性和可比性。使用标准矩阵报告框架清楚地列出了项目、上下文和社区系统的结构。据报道,有两个分流方案证明了矩阵的使用。尽管不同的司法管辖区有广泛的机构和资源可用于支持转移,并且可能会以不同的方式处理这一概念,但标准化和精简报告将有助于评估转移和制定可持续的方案。

Re-Envisioning Public Safety Through an Embedded Police Social Worker (PSW) Model: A Promising Approach for Multidisciplinary Resource Delivery and Diversion 通过嵌入式警察社会工作者(PSW)模式重新设想公共安全:一种有前途的多学科资源交付和转移方法

Cities across the political spectrum in the United States are shifting toward co-responder models that involve social workers with police departments in some capacity, but research is lagging about the proper role of police social workers (PSWs). This case study explores how the micro and macro roles of the embedded PSW model can improve resource delivery and divert people in crisis away from the criminal justice system. Few research studies to date have explored the role and potential effectiveness of creating such a position within police departments. An analysis of 7 months of data found that the PSW was much more efficient than officers in making referrals for high-needs clients. Furthermore, high-needs clients were more likely to have unmet basic needs such as shelter, food, and health care, indicating that police departments may frequently interact with people who have high levels of such needs. Qualitative case notes also revealed that PSWs can divert individuals from the criminal justice system by using crisis intervention and de-escalation techniques on-scene with clients. This research has important implications for improving community safety and well-being, and this case study reveals that PSWs with micro and macro skills are a promising model for improving public safety and justice in the right context.
美国各个政治派别的城市都在转向社会工作者与警察部门以某种身份参与的共同响应模式,但对警察社会工作者(PSW)的适当作用的研究却滞后。本案例研究探讨了嵌入式PSW模型的微观和宏观作用如何改善资源交付,并使处于危机中的人们远离刑事司法系统。迄今为止,很少有研究探讨在警察部门设立这样一个职位的作用和潜在效力。对7个月数据的分析发现,在为高需求客户进行转介方面,PSW比官员效率高得多。此外,高需求客户更有可能有未满足的基本需求,如住所、食物和医疗保健,这表明警察部门可能经常与高需求人群互动。定性案例说明还显示,PSW可以通过在现场与客户一起使用危机干预和降级技术,将个人从刑事司法系统中转移出去。这项研究对改善社区安全和福祉具有重要意义,本案例研究表明,具有微观和宏观技能的PSW是在正确的背景下改善公共安全和正义的一个很有前途的模式。

Despite its importance for testing criminological theories and informing crime control policy, forecasting crime rates has all but disappeared from criminology. We argue for a resurgence of crime forecasting in the study of crime trends. As an example of the value, as well as the challenges, of forecasting, we engage in a forecasting exercise based on data from New York City. We discuss each of the steps taken to forecast New York’s violent and property crime rates to 2024, from preparing the data for reliable analysis, specifying the forecasting model, selecting the forecasting method, and validating the results. The results of autoregressive integrated moving average (ARIMA) forecast models show a rise in New York’s violent and property crime rates in 2022 and 2023 before flattening in 2024. Renewed attention to forecasting can help to secure the future of the study of crime trends.
尽管预测犯罪率对检验犯罪学理论和为犯罪控制政策提供信息很重要,但它几乎已经从犯罪学中消失了。我们主张在研究犯罪趋势时重新进行犯罪预测。作为预测价值和挑战的一个例子,我们根据纽约市的数据进行了预测。我们讨论了预测2024年纽约暴力和财产犯罪率所采取的每一个步骤,从准备数据进行可靠分析、指定预测模型、选择预测方法到验证结果。自回归综合移动平均(ARIMA)预测模型的结果显示,纽约的暴力和财产犯罪率在2022年和2023年有所上升,2024年趋于平缓。重新关注预测有助于确保犯罪趋势研究的未来。

Renewed attention to forecasting can help to secure the future of the study of crime trends.","PeriodicalId":47370,"journal":{"name":"Journal of Contemporary Criminal Justice","volume":" ","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49583120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research presents the outcomes of a substance use diversion program in a Midwestern county. Specifically, this work assesses the efficacy (operationalized through re-arrest) and cost-efficacy (operationalized through cost per 1% reduction in re-arrest likelihood) of the program across varying levels of American Society of Addiction Medicine levels of care (ASAM LOC). Using a sample of 430 program participants, findings illustrate that the program overall reduced the likelihood of re-arrest over both a 6- and 12-month horizon across program completers. However, more granular analyses revealed differences across ASAM LOC; the most statistically robust form of treatment was the most intensive 3.5 ASAM LOC, which led to an 82% reduction in 6-month re-arrest and an 80% reduction in 12-month re-arrest for those who completed the program relative to those who did not. The 3.5 ASAM LOC was also the most cost-effective among those explored, costing $66.04 per 1% reduction in recidivism. The outcomes of this work emphasize (a) the relevance of the ASAM LOC in determining program efficacy and (b) the need for varying levels of treatment intensity to better accommodate the needs of substance use disorder diversion participants.
本研究提出了在中西部县的物质使用转移计划的结果。具体而言,本研究评估了该项目在美国成瘾医学协会(ASAM LOC)不同级别护理水平上的有效性(通过再次逮捕进行操作)和成本效益(通过每减少1%再次逮捕可能性的成本进行操作)。通过对430名项目参与者的抽样调查,结果表明,该项目总体上降低了项目完成者在6个月和12个月期间再次被捕的可能性。然而,更细致的分析揭示了ASAM LOC之间的差异;统计上最稳健的治疗形式是最强化的3.5 ASAM LOC,相对于那些没有完成该计划的人,完成该计划的人6个月再被捕率降低82%,12个月再被捕率降低80%。3.5 ASAM LOC也是所有研究中最具成本效益的,每减少1%的再犯成本为66.04美元。这项工作的结果强调了(a) ASAM LOC在确定项目有效性方面的相关性,以及(b)需要不同程度的治疗强度,以更好地适应物质使用障碍转移参与者的需求。

This article explores whether there was a universal increase in homicide victimization in 2014 to 2016 and 2019 to 2020. Although the United States observed increases in homicide victimization in 2014 to 2016 and 2019 to 2002, it is unlikely that all nations observed simultaneous increases in homicide victimization. Therefore, we explore whether countries observed increases in homicide victimization from 2014 to 2016, only part of the time, and before and after 2014 to 2016. We also investigated which nations observed an increase in homicide victimization from 2019 to 2020. We used WHO mortality homicide victimization data for an initial sample of 116 nations. In general, it does not appear that there was a simultaneous universal increase in the times under study. However, most of the sample at some point between 2014 and 2016 experienced increases in homicide victimization.
本文探讨了2014年至2016年和2019年至2020年的凶杀案受害是否普遍增加。尽管美国在2014年至2016年和2019年至2002年期间观察到凶杀案受害人数增加,但不太可能所有国家都观察到凶杀案受害人数同时增加。因此,我们探讨了各国在2014年至2016年期间是否观察到杀人受害者增加,只是部分时间,以及2014年至2016年前后。我们还调查了从2019年到2020年,哪些国家的凶杀案受害人数有所增加。我们在116个国家的初始样本中使用了世卫组织杀人死亡率受害数据。总的来说,在研究期间似乎并没有同时出现普遍的增长。然而,在2014年至2016年的某个时候,大多数样本都经历了凶杀案受害者的增加。

Within the crime trends literature, there exist several notable studies that have examined the linkages between various economic measures and trends in violent and property crime. This research expands on that literature by examining whether and to what extent racial income gaps are related to changes in city-level crime. Pulling together data from the Uniform Crime Report, U.S. Census, and American Community Survey, this project focuses on homicide and violent crime trends of 73 cities from 2006 to 2020 and changes in city-level racial-ethnic income gaps. This study employs a series of multilevel longitudinal models to measure whether changes in this income gap, whether widening or constricting, are related to changes in rates of violent crime and homicide both within and between cities. Results find that changes in any of the racial-ethnic income gaps tested are not related to trends in violent crime and homicide within or between cities. However, the inclusion of the White-Hispanic income gap and total income gap explained sizable portions of the between-city and within-city rates of violence and homicide.
在犯罪趋势文献中,有几项值得注意的研究审查了各种经济措施与暴力和财产犯罪趋势之间的联系。这项研究通过考察种族收入差距是否以及在多大程度上与城市一级犯罪的变化有关,对这些文献进行了扩展。该项目汇集了《统一犯罪报告》、《美国人口普查》和《美国社区调查》的数据,重点研究了73个城市2006年至2020年的凶杀和暴力犯罪趋势,以及城市层面种族收入差距的变化。这项研究采用了一系列多层次的纵向模型来衡量这种收入差距的变化(无论是扩大还是缩小)是否与城市内部和城市之间的暴力犯罪率和凶杀率的变化有关。结果发现,任何种族和民族收入差距的变化都与城市内部或城市之间的暴力犯罪和凶杀趋势无关。然而,白人和西班牙裔的收入差距和总收入差距在很大程度上解释了城市间和城市内的暴力和凶杀率。
