Prospective investigations have demonstrated support for the cycle of violence theory. However, few studies have examined whether or not abuse occurring during adolescence increases the prevalence and frequency of criminal involvement, or explored the long-term consequences of such victimization. In addition, there has been little investigation of whether or not the effects of abuse vary depending on characteristics of the victim, such as sex, race/ethnicity, age, family structure or income. Using data from the National Youth Survey, this study demonstrates that adolescent physical abuse has immediate and enduring effects on the prevalence and frequency of a variety of self-reported offenses, including violent and non-violent crimes, drug use and intimate partner violence. Furthermore, the study reveals that while victimization increases the prevalence of offending for victims of varying backgrounds, the frequency of offending is moderated by family income, area of residence, and family structure. Implications for prevention are discussed.  相似文献

走私、贩卖、运输、制造毒品罪中的"未经处理"只能解释为"未经刑事处罚",将非刑罚处置措施、行政责任或者其他法律责任视为对走私、贩卖、运输、制造毒品行为的处理方式是缺乏法律根据的。但是如此解释仍然存在一些问题,如使得刑罚过于严厉、影响刑法用语的统一性等,但是对于这些问题,非刑法解释所能为之,只能够通过刑事立法予以解决。  相似文献

物流毒品犯罪是随着我国物流行业的发展而产生的一种新兴的犯罪,由于物流毒品犯罪具有成本低、跨度大、渠道多、侦破难度大、容易逃避打击等特点,近年逐渐发展成为贩毒分子进行犯罪活动的重要方式,这一犯罪方式严重危害了我国的社会管理秩序。侦查机关只有加深对物流毒品犯罪特点的认识和了解,充分运用各种侦查措施和手段,才能提高对物流毒品犯罪的打击力度和精度。  相似文献

Drug-facilitated sexual assault (DFSA) has been defined as the use of a chemical agent to facilitate a sexual assault. We report two cases of the use of tetrahydrozoline for DFSA. We believe this is the first report with urinary quantification of tetrahydrozoline levels postassault. Blood and urine were obtained c. 20 h postexposure in two cases of reported DFSA. Tetrahydrozoline was not detected in blood but was identified in urine in both victims. After initial identification in the urine using the 2010 update to the AAFS mass spectrometry database library, tetrahydrozoline was quantified at 114 and 150 ng/mL, respectively, using GC/MS. Two unique clinical features reported in these cases were intermittent periods of consciousness and postexposure vomiting. Use of GC/MS was successful in identifying tetrahydrozoline in the 100 ng/mL range up to 20 h postexposure. For victims with late presentation, urine may be a better sample for evaluation for tetrahydrozoline.  相似文献

On May 1, 2002, the Philadelphia Police Department launched Operation Safe Streets, stationing officers at 214 of the highest drug activity locations in the city 24 hours a day, 7 days a week. Interrupted time series (AutoRegressive Integrated Moving Average) models on weekly data isolated citywide and local program impacts on all violent crimes, murder, and reported drug crimes. Results showed no significant impacts on citywide weekly counts for drug crimes, homicides, or all violent crimes. Geographically focused analyses showed significant localized intervention impacts for both violent and drug crimes. Analyses of high‐drug‐activity non‐intervention sites suggest: the program impacts seen were not an artifact of history or local history; significant spatial diffusion of preventive benefits for violent crime; and probably significant spatial displacement for drug crime. Stationary targeted drug‐enforcement interventions like Operation Safe Streets may differentially affect the locational selection processes behind violent crime versus drug crime.  相似文献

Even though previous research has not examined mass murder prior to 1965, scholars have asserted that the mid-1960s marked the onset of an unprecedented and ever-growing mass murder wave. Using news accounts and the FBI's Supplementary Homicide Reports (SHR) as sources of data, this study analyzes 909 mass killings that took place between 1900 and 1999. Although the mid-1960s marked the beginning of a mass murder wave, it was not unprecedented, because mass killings were nearly as common during the 1920s and 1930s. The results also show that familicides, the modal mass murder over the last several decades, were even more prevalent before the 1970s. Moreover, mass killers were older, more suicidal, and less likely to use guns in the first two-thirds of the 20th century. Although some have claimed that workplace massacres represent a new “strain” in mass murder, the findings suggest that the only new type of mass killing that emerged during the 20th century was the drug-related massacre.  相似文献

A prominent perspective in the gang literature suggests that gang member involvement in drug selling does not necessarily increase violent behavior. In addition it is unclear from previous research whether neighborhood disadvantage strengthens that relationship. We address these issues by testing hypotheses regarding the confluence of neighborhood disadvantage, gang membership, drug selling, and violent behavior. A three‐level hierarchical model is estimated from the first five waves of the 1997 National Longitudinal Survey of Youth, matched with block‐group characteristics from the 2000 U.S. Census. Results indicate that (1) gang members who sell drugs are significantly more violent than gang members that don’t sell drugs and drug sellers that don’t belong to gangs; (2) drug sellers that don’t belong to gangs and gang members who don’t sell drugs engage in comparable levels of violence; and (3) an increase in neighborhood disadvantaged intensifies the effect of gang membership on violence, especially among gang members that sell drugs.  相似文献

Social control in urban neighborhoods has been studied for over a century in America, yet our understanding of the dynamic nature of social relations for exerting informal social control remains limited. The present study uses detailed reports from those most likely to be the target of local control efforts—violent youth in extremely disadvantaged urban locations—to re‐examine two features of this work: variations across different hypothetical scenarios widely used in this research, and connections between local ties and intervention type and likelihood in actual events. In‐depth qualitative interviews from 159 violent males aged 16–24 from two distressed New York City neighborhoods identify ways in which responses to commonly used scenarios of informal social control are age‐ and space‐graded. Reports on the transactional nature of social control in violent events show how local ties may undermine, rather than support, social control processes. It would appear that we need to consider more carefully general suggestions about local ties encouraging more informal social control, move to a more textured, multithreaded view of these connections, and incorporate age‐ and space‐graded dynamics into future studies of social control.  相似文献

The ability to detect low level DNA brings with it the uncertainty of whether the detected DNA is a result of transfer. To address this uncertainty, a simulation study was conducted in which a mock illicit drug packet was placed into the personal bags of individuals. When the average transit time of the packets was increased from around 2 h to more than 14 h, the percentage of the DNA profiles recovered from the packets which could be attributed to the individuals increased greatly from 5.3% to 48.6%. We found that drug packers who were poor shedders could not be included as contributors to the DNA profiles from the drug packets at all and there was a higher chance that individuals other than themselves could be included as contributors to the DNA profile recovered from drug packets. We also found that it was equally likely that the drug packers who had direct contact with the drug packets and bag owners who did not, could be included as contributors to the DNA profiles recovered from the packets. The results in this study highlight the importance of taking into consideration the transit time of drug packet, the shedder status of the alleged packer and the history of an item, when evaluating DNA evidence in the context of illicit drug activities.  相似文献
