Drug-facilitated sexual assault using tetrahydrozoline

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.     

Police Officers on Drug Corners in Philadelphia,Drug Crime,and Violent Crime: Intended,Diffusion, and Displacement Impacts

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.     

The patterns and prevalence of mass murder in twentieth-century America

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.     

Gang Membership,Drug Selling,and Violence in Neighborhood Context

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.     

The Effects of Juvenile Transfer to Criminal Court on Incarceration Decisions

The present study examined the effects of institutional pressures on homeland security preparedness among law enforcement agencies in Illinois. The data come from the Illinois Homeland Security Survey (IHSS). Specifically, the study employed three theories to explain homeland security preparedness: contingency theory, resource dependence theory, and institutional theory. We hypothesized that institutional pressures will lead to isomorphism as agencies attempt to conform to institutional expectations about appropriate activities in a homeland security era. To evaluate these theories and their impact on homeland security practices, the authors used confirmatory factor analysis. The IHSS data lend strong support to the application of organizational theory as a lens through which homeland security preparedness can be understood. Institutional pressures, such as professional and government publications, training, professional associations, and the actions of peer agencies, significantly influenced municipal and county agencies in Illinois. Funding, while often thought important to encourage preparedness, was not a significant predictor. The results of this analysis advance our understanding of homeland security preparedness via institutional theory by suggesting that the larger environment is salient.     

Local Social Ties and Willingness to Intervene: Textured Views Among Violent Urban Youth of Neighborhood Social Control Dynamics and Situations

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.     

Juvenile Court Context and Detention Decisions: Reconsidering the Role of Race,Ethnicity, and Community Characteristics in Juvenile Court Processes

The relationship between race/ethnicity, community dynamics, and juvenile court processes has long been established. Prior research has relied on city‐ or county‐level measures of community characteristics (e.g., racial composition, poverty) to examine how racial groups are processed within juvenile courts. To date, no study has utilized finer scale measures of geographic areas to examine how characteristics of juveniles’ communities impact court decisions. By utilizing official juvenile court data from a city in the southwest, this study draws upon attribution theory to examine how economic and crime community‐level measures directly and indirectly influence detention outcomes. Findings reveal that the effect of race and ethnicity in detention outcomes varies across communities, and the effect of ethnicity in detention decisions is mediated by economic community‐level measures. The theoretical and policy implications of the study findings are discussed.     

法院在防治家庭暴力中的作用实证研究——以重庆市某区人民法院审理涉及家庭暴力案件情况为对象

通过实证调研,其结果显示家庭暴力的发生率仍然较高,并且当事人呈现出性别、年龄、职业等方面的特点。人民法院在涉家庭暴力案件的审理过程中,既有家庭暴力认定、举证责任分配、人身安全保护裁定送达、调解方法上的有益经验,也面临着防治家庭暴力立法及反家庭暴力联动机制不完善、人身安全保护裁定的局限性、取证难等一些困境。建议我国尽快制定一部统一的"家庭暴力防治法",在加强防治家庭暴力宣传的同时,明确规范各相关部门的职责与责任,加强各部门之间的联动协作。     

法国重罪陪审制度的启示与借鉴

陪审制度具有重要的政治意蕴与司法功能。在法国,对于法定刑较重的重大案件,实行以随机方式抽选一般国民担任陪审员,由陪审员与职业法官组成合议庭,共同审理案件,一起决定定罪量刑的制度。法国重罪陪审制度对于完善我国人民陪审员制度,如构建重罪、复杂案件由陪审团审理的制度,取消对陪审员学历的要求、确立科学的陪审员遴选程序与陪审团评议表决程序方面具有重要的借鉴意义。
