POVERTY,INFANT MORTALITY,AND HOMICIDE RATES IN CROSS-NATIONAL PERSPECTIVE: ASSESSMENTS OF CRITERION AND CONSTRUCT VALIDITY*

This article assesses the extent to which the infant mortality rate might be treated as a “proxy” for poverty in research on cross-national variation in homicide rates. We have assembled a pooled, cross-sectional time-series data set for 16 advanced nations from the 1993–2000 period that includes standard measures of infant mortality and homicide and contains information on the following commonly used “income-based” poverty measures: a measure intended to reflect “absolute” deprivation and a measure intended to reflect “relative” deprivation. With these data, we assess the criterion validity of the infant mortality rate with reference to the two income-based poverty measures. Also, we estimate the effects of the various indicators of disadvantage on homicide rates in regression models, thereby assessing construct validity. The results reveal that the infant mortality rate is correlated more strongly with “relative poverty” than with “absolute poverty,” although much unexplained variance remains. In the regression models shown here, the measure of infant mortality and the relative poverty measure yield significant positive effects on homicide rates, whereas the absolute poverty measure does not exhibit any significant effects. The results of our analyses suggest that it would be premature to dismiss relative deprivation in cross-national research on homicide, and that disadvantage is conceptualized and measured best as a multidimensional construct.     

Toxicology and Circumstances of Death of Homicide Victims in New South Wales, Australia 1996–2005

Abstract:  To determine the prevalence and circumstances of psychoactive substances amongst homicide victims, 485 consecutive cases autopsied at the NSW Department of Forensic Medicine (1/1/1996–12/31/2005) were analyzed. Substances were detected in 62.6% of cases, and illicit drugs in 32.8%. Alcohol, cannabis, opioids, and psychostimulants were most commonly detected. Alcohol and cannabis were both more prevalent amongst males. Mean ages were significantly younger for decedents who tested positive for a substance and for an illicit drug. Cases where death resulted from a physical altercation were more likely to have had alcohol and cannabis present. Illicit drugs were prominent amongst firearms deaths. The proportion of alcohol positive cases increased from 25.0% on Monday to 49.4% for Saturdays/Sundays. Alcohol was more common in incidents in the 0001–0600 h and 1800–2400 h periods. Psychoactive substances appear to substantially increase the risk of homicide, although there are important differences between drug classes in the circumstances of such incidents.     

“命案必破”辨思

公安部自2004年提出“命案必破”号召至今，期间几次重中其重要性与坚持的决心。地方公安机关也纷纷采取措施响应该号召，力求实现这一目标。实践表明，命案必破确在命案本身的侦破上；另一方面在带动其他案件的侦破以及提高打击刑事犯罪的整体能力上体现出了积极效果。命案的侦破不能逾越认识规律和正当法律程序这两个界限，否则“命案必破”号召的初衷将难以实现。     

IMMIGRATION AND CRIME IN AN ERA OF TRANSFORMATION: A LONGITUDINAL ANALYSIS OF HOMICIDES IN SAN DIEGO NEIGHBORHOODS, 1980–2000*

Emerging research associated with the “immigration revitalization” perspective suggests that immigration has been labeled inaccurately as a cause of crime in contemporary society. In fact, crime seems to be unexpectedly low in many communities that exhibit high levels of the following classic indicators of social disorganization: residential instability, ethnic heterogeneity, and immigration. But virtually all research conducted to date has been cross-sectional in nature and therefore unable to demonstrate how the relationship between immigration and crime might covary over time. This limitation is significant, especially because current versions of social disorganization theory posit a dynamic relationship between structural factors and crime that unfolds over time. The current study addresses this issue by exploring the effects of immigration on neighborhood-level homicide trends in the city of San Diego, California, using a combination of racially/ethnically disaggregated homicide victim data and community structural indicators collected for three decennial census periods. Consistent with the revitalization thesis, results show that the increased size of the foreign-born population reduces lethal violence over time. Specifically, we find that neighborhoods with a larger share of immigrants have fewer total, non-Latino White, and Latino homicide victims. More broadly, our findings suggest that social disorganization in heavily immigrant cities might be largely a function of economic deprivation rather than forms of “neighborhood” or “system” stability.     

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.

论交通肇事后“因逃逸致人死亡”

我国刑法第133条规定,“交通肇事后,因逃逸致人死亡的,处7年以上有期徒刑。”由于立法的不明确,在理解“因逃逸致人死亡”的问题上,众说纷纭,可谓百家争鸣。对于“因逃逸致人死亡”的定性与处罚,不能不加区分地一律适用刑法第133条第3档法定刑,而应根据刑法的具体规定,结合行为人的主客观情况,作出正确的定罪与量刑。     

Intimate Homicide and the Provocation Defence – Endangering Women? R v. Smith

This case note considers the availability in the United Kingdom of the provocation defence in cases of intimate homicide in the context of the recent House of Lords decision in Rv. Smith [2000] 3 W.L.R. 654. The note argues that the expansion of the objective component of the defence to encompass the mental infirmities of individual defendants is dangerous for women. Although it has the potential to help some abused women who kill to use the defence, it has, at the same time, exposed women who are abused by sexually possessive, violent men to even greater danger. It is thus argued that the defence should be restricted in the way envisaged by the minority judgement of Lord Millett so that abused women will still be able to use the defence, but by anon-medical route. Alternatively, the defence should be abolished and defences which pose no risk of encompassing violent men should be developed to accommodate abused women. This revised version was published online in July 2006 with corrections to the Cover Date.     

Fatal footsteps: murder of undocumented border crossers in Maricopa County, Arizona

In the past 5 years, the mortality rate among undocumented workers in Arizona has increased steadily. In 1998-1999, the number of deaths among border crossers was 28. That number increased dramatically in 1999-2000 to 106 and has exceeded 200 in each of the past 2 years. In the past, many immigrant deaths occurred as a result of dehydration and exposure (1). More recently, a new trend has emerged, that is, death of border crossers at the hands of the persons ("coyotes") hired to lead them across the border to safety. In some cases, the smugglers attempt to extort additional money from the families by holding the victims hostage once they have crossed the border into the United States. If the families fail to pay, the hostage is killed. Rival gangs are also murdering one another over their human cargo. Nine recent cases illustrate this trend in Maricopa County. In each example, the victims were bound, shot (or in one instance stabbed) and dumped in a remote desert area. All of the decedents were linked to murder for extortion by the 'coyotes' or rival gang members.
