The objective of this study was to identify the number and subtypes of homicide-suicides in the United States by age group and state over a 3-year period from 1997 through 1999. A total of 673 homicide-suicides, including 674 perpetrators and 779 victims, were identified from Internet searches of 191 national newspapers, and they were classified according to a modified Hanzlick-Koponen typology. One quarter of the homicide-suicides were perpetrated by persons 55 years or older, and 77% were spousal/consortial, higher than the 57% observed in the younger age group; 11% of the older homicide-suicides were familial, compared with 16% in the younger age group. Whereas only 3% of older homicide-suicides were infanticide/pedicide, 16% of the younger homicide-suicides involved parents killing their children. Forty-five states, including the District of Columbia, reported a homicide-suicide during the 3-year period, and they occurred most frequently in Florida (163), California (98), Texas (36), and New York (35). Newspaper surveillance is useful to identify where homicide-suicides are occurring most frequently, but they are underestimates of the true prevalence. However, the number of incidents detected is large enough that the cases detected may be a fairly representative sample. 相似文献

The main purpose of this study was to present changes occurring between 2002 and 2004 in the prevalence of psychosocial constraints and interpersonal violence at work among officers working in correctional facilities in Quebec. Results suggest that in the absence of specific organizational intervention aimed at improving a deleterious work situation, exposure to low decision latitude remained similar between 2002 and 2004, while exposure to high psychological demands improved somewhat, for both men and women. In 2000, rates of exposure of correctional officers in Quebec to high psychological demands, low decision latitude and the combination of high psychological demands and low decision latitude (job strain) were significantly higher than those obtained for the entire population of workers in Quebec in contact with the public. Exposure of correctional officers in Quebec to intimidation at work increased substantially between 2002 and 2004, among both men and women. Globally speaking, rates of exposure to intimidation by colleagues and superiors practically doubled between 2000 and 2004. Rates of exposure to intimidation among correctional officers in Quebec were particularly high in 2004 (71% among men 66% among women) compared to rates in another study conducted among federal correctional officers (48%) by Samak. The present study also showed that in 2004, correctional officers in Quebec were more likely to present signs of psychological distress linked with work when they were exposed to high psychological demands, low decision latitude, job strain and poor social support from superiors and colleagues. Psychological distress was also shown to be greater when reward at work was scarce and when there was an imbalance between effort and reward at work. Finally, in 2004, psychological distress among correctional officers was also associated with intimidation and psychological harassment at work. 相似文献

The world studied by empirical criminal justice research is babble—a congeries of voices whose meanings represent many normative
worlds. Our research designs provide a frame for the babble, and our statistics codify and simplify it. We provide analytic
portraits of it and, using the substantive language of crime control, give those portraits meaning. Yet, those meanings are
located in a crime control discourse that de-legitimizes and destroys those normative worlds. This paper, an interpretive
montage, is a collection of fractured narratives assembled to show that interpretation has something to offer the way we think
about knowledge production in the field of criminal justice. It is also a cautionary tale to students in criminal justice,
to remember that our scientific abstractions are an abstraction from the underlying realities of human life, not a “deeper”
or in some way more real understanding. Our aim is to move the babble—the humanity from which the voices emerge—back into
the foreground of justice research.

Why has the probability of going to prison after a felony conviction increased since the early 1980s? Social scientists often try to answer this question through macro‐level research that is aimed at examining correlations between prison admissions and crime rates or sociopolitical characteristics of states. That type of macro‐level inquiry, however, does not allow for a close examination of how characteristics of offenders changed over time, and whether such changes are consequential for understanding trends in the use of imprisonment. In the current study, I take a different approach—one in which case‐level data are observed over a lengthy time span—to investigate why the likelihood of going to prison for a given crime persistently increased for several decades. The results of analyses of more than 350,000 felony cases sentenced in Minnesota during a 33‐year period show that the probability of a defendant receiving a prison sentence increased from 1981 to 2013, as would be expected. The primary reason for the rising probability of imprisonment was the significant increase in the average offender's criminal record, which more than doubled during the observation period. 相似文献

Effect of Sterilants on Amplification and Detection of Target DNA from Bacillus cereus Spores 下载免费PDF全文
James M. Robertson Ph.D. Douglas L. Anders Ph.D. Francene Basalyga M.D. Julie Millar M.F.S. Donia Palomo Slack M.S. Robert Bever Ph.D. 《Journal of forensic sciences》2018,63(3):699-707
To conceal criminal activity of a bioterrorist or agroterrorist, the site of pathogen generation is often treated with sterilants to kill the organisms and remove evidence. As dead organisms cannot be analyzed by culture, this study examined whether DNA from sterilant‐treated Bacillus cereus spores was viable for amplification. The spores were exposed to five common sterilants: bleach, Sterilox®, oxidizer foam (L‐Gel), a peroxyacid (Actril®), and formaldehyde vapor. The spores were inoculated on typical surfaces found in offices and laboratories to test for environmental effects. It was found that the surface influenced the efficiency of recovery of the organisms. The DNA isolated from the recovered spores was successfully detected using RT‐qPCR for all treatments except for formaldehyde, by amplifying the phosphatidylinositol phospholipase C and sphingomyelinase genes. The results demonstrated that evidence from sites treated with sterilants can still provide information on the uncultured organism, using DNA amplification. 相似文献
