An Assessment of the Quality of Homicide Data in the Supplementary Homicide Reports: A Research Note

The Federal Bureau of Investigation (FBI)’s Supplementary Homicide Reports (SHR) is a national-level incident-based data clearinghouse for homicide events in the USA used in countless research studies to track homicide trends, test theory, and analyze policy. Despite its wide use, the SHR has well-known limitations. This research note examines the accuracy of the information in the SHR by comparing homicide cases in Newark, New Jersey with their respective data to determine the level of disagreement between the data sources, which variables exhibit the greatest disagreement, and the case-related variables related to the disagreement. Uniquely, we do this for cases where offenders are known in the SHR. Our findings suggest that variables such as victim-offender relationship and circumstance have high disagreement even when the SHR reports an offender, and that the most important covariate of this is time to close the homicide investigation with an arrest. Research implications of the results are discussed.     

The Spatial Patterning of County Homicide Rates: An Application of Exploratory Spatial Data Analysis

The possibility that homicides can spread from one geographic area toanother has been entertained for some time by social scientists, yetsystematic efforts to demonstrate the existence, or estimate the strength,of such a diffusion process are just beginning. This paper uses exploratoryspatial data analysis (ESDA) to examine the distribution of homicides in 78counties in, or around, the St. Louis metropolitan area for two timeperiods: a period of relatively stable homicide (1984–1988) and aperiod of generally increasing homicide (1988–1993). The findingsreveal that homicides are distributed nonrandomly, suggestive of positivespatial autocorrelation. Moreover, changes over time in the distribution ofhomicides suggest the possible diffusion of lethal violence out of onecounty containing a medium-sized city (Macon County) into two nearbycounties (Morgan and Sangamon Counties) located to the west. Althoughtraditional correlates of homicide do not account for its nonrandom spatialdistribution across counties, we find some evidence that more affluentareas, or those more rural or agricultural areas, serve as barriers againstthe diffusion of homicides. The patterns of spatial distribution revealedthrough ESDA provide an empirical foundation for the specification ofmultivariate models which can provide formal tests for diffusion processes.     

Beyond the Social Production of Homicide Rates: Extending Social Disorganization Theory to Explain Homicide Case Outcomes

This paper examines the intersection of social disorganization at a community level with responses to crime. In contrast to other works examining the impact of social disorganization on the production of crime rates, we examine the role of social disorganization theory in responses to crime rates (i.e. the arrest and conviction of perpetrators of crime). In an effort to examine these dynamics, we use law enforcement data from Cleveland, Ohio to explore the role of social disorganization in the ability of police and the courts to respond to homicide cases. Such an examination suggests not only how far the law extends in community responses to homicide but also reveals an extension of social disorganization theory beyond its established role in explaining the production of crime rates.     

Economic Development,Change of Age Distribution,and Stream Analogy of Homicide and Suicide: A Cross-National Assessment

The current study tests the stream analogy of lethal violence, proposed by Unnithan et al. on a large sample of 124 nations. Spatial econometric regression models confirm that economic development decreases homicide rate and increases suicide–homicide ratio (SHR). The SHR developed by Unnithan et al. accounts for the impact of economic development better than original measure of suicide rate. The most important finding of the current investigation is that the increase in the population size of the elderly, consequent to economic development, is partially responsible for elevated suicide rates and SHRs.     

The Relationship Between Gender Equality and Rates of Inter- and Intra-Sexual Lethal Violence: An Exploration of Functional Form

Considerable attention has been given to the relationship between gender equality (GE) and levels of violence perpetrated by men against women in recent decades. Yet, the current state of the literature is equivocal. High levels of GE have been hypothesized to both decrease and increase men’s violence. This study proposes a theoretical account that integrates the ameliorative and backlash theses and offers a possible explanation for some of the inconsistent findings. Specifically, we argue that both ameliorative and backlash processes operate but that their relative strength and salience vary at different levels of GE. As a result of the interplay between these counter-balancing forces, the relationship between GE and levels of men’s violence men against women (and other men) is hypothesized to be curvilinear rather than linear. The results of multivariate analyses of male and female inter- and intra-sexual homicide offending offer robust support for this hypothesis.     

The Application of Missing Data Estimation Models to the Problem of Unknown Victim/Offender Relationships in Homicide Cases

Homicide cases suffer from substantial levels of missing data, a problem largely ignored by criminological researchers. The present research seeks to address this problem by imputing values for unknown victim/offender relationships using the EM algorithm. The analysis is carried out first using homicide data from the Los Angeles Police Department (1994-1998), and then compared with imputations using homicide data for Chicago (1991-1995), using a variety of predictor variables to assess the extent to which they influence the assignment of cases to the various relationship categories. The findings indicate that, contrary to popular belief, many of the unknown cases likely involve intimate partners, other family, and friends/acquaintances. However, they disproportionately involve strangers. Yet even after imputations, stranger homicides do not increase more than approximately 5%. The paper addresses the issue of whether data on victim/offender relationships can be considered missing at random (MAR), and the im-plications of the current findings for both existing and future research on homicide.     

An Empirical Analysis of 30 Years of U.S. Juvenile and Adult Sexual Homicide Offender Data: Race and Age Differences in the Victim–Offender Relationship

Abstract: Little is known about the racial patterns of crimes committed by sexual homicide offenders (SHOs). This study examined race and age influences on victim–offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976–2005) was used. Analyses of victim–offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race‐ and age‐based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, “intra‐racially” (range 91–100%) across four victim age categories, whereas Black SHOs killed both intra‐racially (range 24–82%) and inter‐racially (18–76%), with the likelihood of their killing inter‐racially increasing as the age of the victim increased. This study underscores the importance of considering victim–offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling.     

收入差距、经济增长与中国的财产犯罪——1978-2005年的实证研究

通过对中国1978-2005年间收入差距、经济增长等宏观经济因素对财产犯罪的影响所进行的实证研究发现,全国、城镇内部、农村内部以及城乡之间的收入差距对财产犯罪产生了显著的影响,经济增长与财产犯罪呈显著的负相关关系,同时中国的财产犯罪还表现出明显的惯性特征。而诸如人均GDP、城市化、福利开支等虽然对财产犯罪产生了影响,但都不显著。     

Compatibility Between Mental Disorder and Mental Capacity: Analysis of a Particular Case of Group Sexual Homicide

Abstract: On the night of August 19, 2000, at the foot of Castel del Monte, an 8‐year‐old girl was brutally murdered. The perpetrators were identified as five young men who captured their victim and sexually abused her. The policemen found the cadaver by following “Mario,” one of the five, who had been discovered lying on the ground, near the castle. Investigation led to demonstrate that the murder was not premeditated. The only desire of the group was to sexually molest the little girl. Mario showed signs of psychiatric pathology and for that he underwent psychiatric evaluation by judicial authorities. Analysis of this case, combined with a criminological and medical‐legal perspective led to conclusions very much different from the expectations of Mario’s defense attorneys. Mario, a marginal figure and seemingly the least intelligent, played the role of group instigator, both in the initiation of sexually abusing the child, as well as in the elimination of an inconvenient witness. However, the group was able to activate Mario’s sadistic fantasies and his sexual perversions, and he ended up in a catalyzing role influencing the behavior of others and realizing what would otherwise remain only fantasies. The circularity of the group allows people like Mario, who are apparently subordinate, to influence the behavior of others. Mario was found to have a mental disorder but it was not sufficient to diminish his personal responsibility related to the crime. In fact, according to Italian judicial code, it is necessary that the motivation for the crime was psychopathological. It was for this reason that, according to Italian law, all of the members of the group were considered to be responsible for the crimes committed and were condemned.

Reconsidering the Relationship Between Welfare Spending and Serious Crime: A Panel Data Analysis with Implications for Social Support Theory

Several researchers have found an inverse relationship between welfare spending and serious crime. With few exceptions, these findings have been based on cross‐sectional designs, single measures of welfare spending, and few indicators of crime. In response to these limitations, the relationship between welfare spending and crime was reconsidered using panel data from California counties. Fixed‐effects regressions revealed virtually no relationship between several measures of welfare spending and five types of serious crime: (1) homicide; (2) robbery; (3) assault; (4) burglary; and (5) larceny. The estimates were resistant to numerous robustness checks and alternative specifications. The most plausible explanation for the findings is that heterogeneity was not controlled for in previous studies. Implications for social support theory are discussed.     

Juvenile and Adult Offenders Arrested for Sexual Homicide: An Analysis of Victim–Offender Relationship and Weapon Used by Race*

Abstract: Limited information is available on racial offending patterns of sexual homicide offenders (SHOs). This study used a 30‐year U.S. Supplementary Homicide Reports sample of SHOs arrested in single‐victim situations (N = 3745). The analysis strength was used to determine whether the findings yielded meaningful patterns for offender profiling. Several important findings emerged for the juvenile offenders. Juvenile White SHOs were likely to target victims with whom they shared a mutual relationship. In contrast, Black juveniles were equally likely to murder strangers and those with whom they had prior and familial relationships. Notably, no juvenile Black SHOs were arrested for murdering intimate partners. Juvenile White SHOs were twice as likely to use edged weapons as their Black counterparts. Black juveniles, conversely, were more likely than White juveniles to use personal weapons. Beyond these findings, known victim–offender relationships and weapon used may not have significant utility for investigators in identifying the SHO race, even after controlling for offender age. Limitations and future directions are discussed.     

Self-Control,Violent Offending,and Homicide Victimization: Assessing the General Theory of Crime

Criminologists have long recognized that offending and victimization share common ground. Using Gottfredson and Hirschis general theory of crime, with its emphasis on self-control as a theoretical backdrop, we examine the extent to which self-control is related to both violent offending and homicide victimization. To examine this issue, we use 5-year post-parole data on violent offending and homicide victimization from a sample of parolees from the California Youth Authority. Using rare-events logistic regression models, results indicate that self-control is related to each outcome, but that other risk factors are also uniquely related to each outcome. The implications of this study for theory and future research are addressed.To whom correspondence should be addressed: Department of Criminology, Law and Society, University of Florida, P.O.

Homicide and economic change: Recent analyses of the Joint Economic Committee report of 1984

The relation between recession and homicide is classic in the United States. This has been affirmed in the 1976 and 1984 Reports to the Joint Economic Committee (JEC) of the United States Congress. Recent analysis confirms the findings reported in both 1976 and 1984 and demonstrates that the influence of recession on homicide is greater than previously estimated. Differences in the 1976 and 1984 findings on homicide are related to differences in the hypotheses tested, as discussed in detail and highlighted in the 1984 report. JEC staff correctly interpreted and reported the 1984 findings. Reproduction of the 1984 homicide equation is straightforward, provided the same data and any of several standard estimation techniques are used. Evidence does not support any of Cook and Zarkin's claims in their critique of the 1984 homicide equation. The JEC report of 1984 used appropriate techniques in the attempt (a) to ensure that influences attributed to economic changes are not actually due to other social factors and (b) to minimize underspecification of models.

Homicide among Indigenous females in North Carolina:a comparison of publicly generated data and violent death reporting system

Like other minoritized populations,American Indian/Alaska Native(AI/AN)females experience disparate morbidity and mortality outcomes to that of the general US population.This study identified discrepancies in reporting of AI/AN female decedents between the North Carolina Violent Death Reporting System(NC-VDRS)and an online,user-generated database.Female AI/AN decedent data of all ages were collected from the NC-VDRS and compared against that of the publicly available North Carolina Missing and Murdered Indigenous Women(MMIW NC)database for the study period,2004-2019.Twenty-four of the 72 cases matched between data systems(33.3％).Substantive differences between the NC-VDRS and the MMIW NC database were found.Future efforts should be directed towards supporting Indigenous communities with the comprehensive data the NC-VDRS can provide.This paper highlights statewide public health systems like the NC-VDRS supporting community efforts to understand,advocate for,and disseminate information on MMIW.

《欧盟一般数据保护条例》(GDPR)率先在个人数据领域赋予数据主体数据迁移权,成为全球数据保护的立法标杆。数据迁移权的诞生为企业参与数据竞争正向赋能,企业竞争中也存在诸多数据迁移障碍。本文结合欧盟数据迁移权的相关规定,以数据、数据迁移权和数据竞争三要素之间的互动关系为进路,通过剖析数据迁移对企业竞争和创新发展的双向反馈,认为我国不应急于实施数据迁移权,而是将数据迁移权定性为一种柔性权利,按照"三阶段五步骤"的路径规划,逐步建立符合我国国情的数据迁移制度。     

区域金融发展、居民金融资产与收入分配——以重庆市为例

基于重庆市1990~2009年的数据,运用VAR模型和脉冲响应函数,实证分析了金融发展、居民金融资产与收入分配的关系。重庆市金融发展与收入分配之间非同阶单整变量,并不存在长期均衡关系。但在一阶差分VAR模型基础上所做的脉冲响应函数分析表明,金融规模扩大导致收入差距呈现由缩小到扩大再到缩小的过程;金融效率的提高则使收入差距先扩大后缩小。城乡人均储蓄比和城乡房产比都扩大了收入差距,而农村居民非农就业水平的提高则有助于缩小收入差距。     

Understanding the Relationship Between Relative Group Size and Hate Crime Rates: Linking Methods with Concepts

Abstract

In recent studies, Hipp et al. caution that the selection of the appropriate denominator in computing the rate of intra- and inter-group interactions is consequential for key findings. The present study builds on this work and examines whether adjusting for the structural opportunities for any type of interaction affects the observed relationship between hate crime rates and minority group size. We go beyond prior research by computing distinctive measures of anti-Black hate crime rates across US counties circa 2000. Our findings offer support for the power-differential hypothesis, revealing a negative effect of minority population size on crime motivated by bias. These results also underline the importance of the procedure developed by Hipp et al., showing that that the selection of the “baseline” for the computation of hate crime rates is critical for understanding the relationship between minority group size and crime motivated by bias.     

Facing death in the early days of life: Inequality between the sexes in enlightenment demographic thought

The first measurements of differential mortality by sex took place at the end of the seventeenth century. Once its existence has been clearly shown during the eighteenth century by the works of Struyck, Kersseboom, Süssmilch, Deparcieux and others, what analysis emerged? If one of the two sexes benefited from a longer life, was this rule valid in all places and for all ages? All the demographers observed that such a difference began during infancy and childhood. How can it be explained that children were not equal in the face of death? Why did so many boys die before their teenage years? We can find several types of explanation: the will of God, the natural order, the biological constitution and the social habits of children of more than one year old.
