Purpose
Extant scholarship has examined pornography's putative link to the commission of sex crime. Yet, virtually no research speaks to whether an offender's exposure to pornography during many different stages of life elevates the violence of a sex offense. The current study addresses this gap.Methods
Using retrospective longitudinal data, we systematically investigate the effect of offender pornography exposure during adolescence, adulthood, and immediately prior to the offense on the level of physical injury as well as the extent of humiliation experienced by sex crime victims.Results
Findings indicate that adolescent exposure was a significant predictor of the elevation of violence—it increased the extent of victim humiliation. Results also suggest a tempering, or cathartic effect of pornography—using pornography just prior to the offense was correlated with reduced victim physical injury. No effects, however, were observed for adult pornography exposure.Conclusion
Pornography use may differentially influence offenders’ propensity to harm or degrade victims over the life course. 相似文献42.

Abstract: Forensic laboratories around the world have seen an increase in the number of drug seizures containing methorphan. Levomethorphan is a narcotic and a controlled substance, and its enantiomer dextromethorphan is an antitussive agent used in over‐the‐counter medications. For the forensic analysis of seized drugs containing methorphan, it is important to report the stereochemical composition of the drug. Ideally, a method based on common forensic laboratory instrumentation is desirable. The use of the chiral derivatizing agent (?)‐menthyl chloroformate followed by routine gas chromatography–mass spectrometry analysis of the derivative was shown to successfully determine the stereochemical composition of methorphan. This approach was applied to a street seizure containing methorphan proving that it was pure dextromethorphan. The derivatives of dextro‐ and levomethorphan were subjected to mass spectroscopic and nuclear magnetic resonance analysis, which confirmed that the structure of the derivatives remained unchanged as a result of the derivatization process. 相似文献

Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics. 相似文献

Purpose
The link between maltreatment and offending has been well established in the literature, with research examining the etiology of criminal behavior consistently documenting the negative effects of experiencing trauma early in life. Theoretically, ideas behind the cycle of violence hypothesis have greatly contributed to our understanding of this connection; however, there is a lack of understanding of the mechanisms underlying this relationship. We address this research gap by examining the mediating role that adolescent mental health, particularly self-image, plays in the relationship between child maltreatment and subsequent adult sex offending.Methods
We utilize retrospective data from a sample of incarcerated sex offenders at a maximum security penitentiary located in Canada (N = 565).Results
Results indicate that poor self-image in adolescence partially mediates the relationship between child maltreatment and the extent of sex offending in adulthood.Conclusions
Implications for research, theory, and policy are discussed. 相似文献46.

Purpose
Research has examined pornography use on the extent of offending. However, virtually no work has tested whether other sex industry experiences affect sex crime. By extension, the cumulative effect of these exposures is unknown. Social learning theory predicts that exposure should amplify offending. Separately, the developmental perspective highlights that the timing of exposure matters.Methods
Drawing on retrospective longitudinal data, we first test whether exposure during adolescence is associated with a younger age of onset; we also examine whether adulthood exposure is linked with greater frequency of offending.Results
Findings indicate that most types of adolescent exposures as well as total exposures were related to an earlier age of onset. Exposure during adulthood was also associated with an overall increase in sex offending, but effects were dependent on “type.”Conclusion
There are nuances in the effect of sex industry exposure on offending patterns. Implications of results are discussed. 相似文献47.

ABSTRACT Recently, states have enacted teacher-carry laws. While controversial, little scholarship has tapped public attitudes toward such reforms. Because public opinion shapes policy, the public is an important stakeholder in this debate. Thus, we investigated three questions. First, how supportive is the public of arming teachers? Second, what demographic and social divides exist, if any, for reform approval? Finally, do crime-related perceptions, concerning views about public safety, and criminogenic influences shape policy preferences? We test these questions using a 2018 poll of Virginia residents (N = 521). Overall, approval for teacher-carry is split. Crime-related perceptions mediate some of the initial social and demographic divides in opinion but other correlates, such as parental status, remain salient predictors of views. Implications are discussed. 相似文献

Objective
This study explores whether the trajectories of recurring victimization of Black persons diagnosed with major mental illnesses vary from the trajectories of their White counterparts. Further, the study examines whether the risk factors for recurring victimization among persons with major mental illness vary by race.Methods
Using data from the MacArthur Violence Risk Assessment Study (MacRisk), two separate hierarchical binomial regression models were estimated to compare the recurring victimization trajectories of Black and White MacRisk participants. Cross-level interaction terms were also estimated to determine if the coefficients for each of the time-varying covariates included in the analyses were significantly different across race.Results
The findings indicate that the trajectories of recurring victimization for Black persons with serious mental illness are significantly different from those of White persons with serious mental illness. Specifically, Black persons’ trajectories remain relatively stable over time, while the risk of recurring victimization declines for Whites as time since release from the hospital increases. Further, the effects of alcohol abuse on revictimization risk vary by race.Conclusion
The findings suggest that the life experiences of Black persons with mental illness may be different from their White counterparts, which is likely to contribute to distinct patterns of recurring victimization over time. Future research should continue to explore recurring victimization among diverse samples to identify potential sources of the variation in revictimization trajectories across race.50.
What is the relationship between ownership type and environmental performance in Chinese firms? Using a survey of over 1,000 industrial firms in 12 Chinese cities in 2006, this article tests a number of competing hypotheses linking ownership type to environmental performance. The results show that small and medium state-owned enterprises (SOEs) on average spend less on pollution abatement technologies and are less likely to meet national emissions standards, compared to privately owned enterprises (POEs) and foreign invested enterprises (FIEs). However, the environmental performance of the largest SOEs matches that of their private and foreign counterparts. These findings are complemented by qualitative interviews and archival research conducted in 2012. 相似文献
