Aim
This study determined the extent to which alcohol and marijuana use during adolescence mediates the relation between transmissible risk for substance use disorder (SUD) and lifetime number of different types of violent offenses.Methods
The transmissible liability index was administered to 359 10-12 year old youths who were tracked to 22 years of age. Past year frequency of alcohol and marijuana consumption was longitudinally tracked to age 22 at which time lifetime violent offenses was recorded.Results
Rate of increase in marijuana use mediated the association between transmissible risk and lifetime number of different types of violent offenses. No association was found between past year frequency of alcohol use and violent offenses.Conclusions
Prevention directed at lowering the psychological characteristics associated with transmissible risk for SUD may also reduce violent offending. 相似文献132.
This study investigates the optimisation of peroxidase based enhancement techniques for footwear impressions made in blood on various fabric surfaces. Four different haem reagents: leuco crystal violet (LCV), leuco malachite green (LMG), fluorescein and luminol were used to enhance the blood contaminated impressions.The enhancement techniques in this study were used successfully to enhance the impressions in blood on light coloured surfaces, however, only fluorescent and/or chemiluminescent techniques allowed visualisation on dark coloured fabrics, denim and leather. Luminol was the only technique to enhance footwear impressions made in blood on all the fabrics investigated in this study. 相似文献

Individuals with severe mental illness (SMI) are at risk for HIV/AIDS. Despite the availability of supportive community programs for those with SMI, there have been no published evaluations of community-level HIV prevention trials among this population. A pilot intervention trial was conducted to determine the feasibility of such an intervention in supportive housing programs (SHPs). A multi-component community-level trial was implemented in two SHPs with a total of 28 residents. Participants completed assessments at three time points: prior to the intervention (baseline), following skills training (post-assessment), and following the 4-month community intervention (follow- up). Results demonstrated significant improvements in psychosocial risk factors at both post- and follow-up assessments, with indications of sexual behavior change at follow-up. The community-level intervention appeared to reduce the risk of HIV among persons with SMI living in SHPs, and supports the importance of conducting larger scale intervention trials. 相似文献

Recent U.S. cases of murders by children below age 11 have captured national headlines. A review of the literature reveals that little is known about this population of juvenile homicide offenders (JHOs). Most studies on juvenile murderers have used small clinical samples, focused on adolescents, and concentrated on male offenders. Studies that have used Supplementary Homicide Report (SHR) data have found significant gender differences among juveniles below 18 years arrested for murder. This study investigated gender differences among 226 juvenile murderers ages 6 through 10 involved in single-victim incidents using bivariate and multivariate statistical techniques. Consistent with previous research, bivariate analyses revealed gender differences with respect to the type of weapon used, age of the victim, relationship to the victim, and circumstances of the crime. Logistic regression analysis identified female JHOs as more likely to use a knife, kill a family member, and kill a victim below age 5, when compared with male JHOs. From these findings, profiles of young male and female JHOs can be drawn. The article concludes with a discussion of the study's implications for prevention and treatment. The authors recommend that future research in gender differences among young children focus on examining psychological, neurological, and sociological variables not included in the SHR data set. 相似文献

Footwear impression lifting and enhancement techniques may be affected by several variables introduced during the production of test footwear impressions, thus limiting the usefulness of enhancement technique comparisons and the results obtained. One such variable is the force applied when the impressed mark is being made. Producing consistent test impressions for research into footwear enhancement techniques would therefore be beneficial. This study was designed to control pressure in the production of test footwear impressions when mimicking a stamping action. Twenty-seven volunteers were asked to stamp on two different surfaces and the average stamping force was recorded. Information from the data obtained was used to design and build a mechanical device which could be calibrated to consistently deliver footwear impressions with the same force onto a receiving surface. Preliminary experiments using this device and different contaminants on the footwear sole have yielded consistent and repeatable impressions. Controlling the variable of pressure for the production of test impressions in this study demonstrated that the differences observed were visual (due to the amount of contaminant transferred and subsequent enhancement) and did not affect the replication of outer sole characteristics. This paper reports the development of the device and illustrates the quality of the impressions produced. 相似文献

Ultra was one of the best-kept secrets of World War Two, concealed for nearly 30 years. A major reason, this article argues, was the precedent set by Churchill's war memoirs, published in 1948–54. The intelligence authorities feared that, if Churchill disclosed anything about Ultra, this would be a green light to those who had worked at Bletchley Park. Using documentation from the Churchill Archives and the Cabinet Office files, the article examines the pressure they successfully put on Churchill and the way Ultra was edited out of his memoirs, looking particularly at big stories such as the battle for Crete, operation Barbarossa, Pearl Harbor and the D-Day deception campaign. 相似文献

AbstractIn late 1976 I spent ten months in Thanjavur District of southeast India, re-studying two villages after an absence of twenty-five years. I had gone back to find out what had happened to the village people, especially with respect to their standard of living, their relations of production and their integration into the world economy. I was particularly interested in the effects of land reforms passed between 1952 and 1974, and of the introduction of “green revolution” technology since 1965. 相似文献
