Abstract: Gunshot deaths in children less than 17 years of age from Adelaide, SA, Australia (1969–2005) and from San Diego County, CA, United States (1988–2005) were compared. Forty-two pediatric gunshot fatalities occurred in South Australia (1.1 cases/year; M:F = 30:12). There were 6 accidents (14%), 14 suicides (33%), and 22 homicides (52%). In San Diego there were 185 cases ( c. 10 cases/year; M:F = 148:37). There were 6 accidents (3%), 42 suicides (23%), 130 homicides (70%), and 7 undetermined cases (4%). The incidence of homicide was significantly higher in San Diego County compared to Adelaide ( p < 0.001), with a higher proportion of murder–suicides occurring in Adelaide. There were markedly more accidents and suicides involving males in Adelaide and a far higher number of male homicide victims in San Diego County compared to females. Rifles of 0.22-caliber were preferred weapons in South Australia, compared to handguns in San Diego County. 相似文献

In Europe, more than 50 approved cultivars of fiber hemp (Cannabis sativa L.) are in agricultural production. Their content of psychoactive tetrahydrocannabinol (THC) is legally restricted to <0.2% (%w/w in the dry, mature inflorescences). Cannabis strains with much higher THC contents are also grown, illegally or under license for drug production. Differentiation between these two groups relies on biochemical quantification of cannabinoid contents in mature floral material. For nonflowering material or tissue devoid of cannabinoids, the genetic prediction of the chemical phenotype (chemotype) provides a suitable method of distinction. Three discrete chemotypes, depending on the ratio of THC and the noneuphoric cannabidiol (CBD), can be distinguished: a “THC-predominant” type, a “CBD-predominant” type, and an intermediate chemotype. We present a systematic genetic prediction of chemotypes of 62 agricultural hemp cultivars grown in Europe. The survey reveals the presence of up to 35% BT allele-carrying individuals (representing either a THC-predominant or an intermediate chemotype) in some cultivars—which is unexpected considering the legal THC limit of 0.2% THC. The fact that 100% of the seized drug-type seeds in this study revealed at least one BT allele, reflects that plant breeding efforts have resulted in a fixation of the BT allele in recreational Cannabis. To guarantee a sincere forensic application based on a genetic chemotype prediction, we recommend not to classify material of unknown origin if the samples size is below nine genetically independent individuals. 相似文献

The association between insect development and temperature is well established. Thermal summation using accumulated degree-day measures is commonly used. However, the time at which evidence is collected is important in these estimates. The aim of this study was to provide a simulated model of the effect of temperatures on six dipteran species commonly associated with cadavers, from the death scene to the refrigerator, and finally at the time of autopsy. Temperatures measurements were sampled over a 16-month period from the external environment (external to the mortuary), within the mortuary refrigerator, and within the mortuary autopsy suite. Monte Carlo simulation using accumulated degree-days (ADD) was used to estimate the variations based on the mean and standard deviation of the temperature measurements. It was found that there was a negative correlation between the base temperature of the fly species (lowest temperature at which the flies will survive) and developmental likelihood. Species with high base temperatures (Chrysomya albiceps, Chrysomya chloropyga, and Musca domestica) were less likely to continue development in refrigerators than species with lower base temperatures (Lucilia sericata and Piophila casei). The findings of this study highlight the importance of recording temperature measurements and the period of refrigeration on PMI estimation especially when continued development occurs in spite of a period of cooling of the insect evidence. 相似文献

Community development corporations (CDC) are a cornerstone of neighborhood improvement in legacy cities. Yet they face challenges that threaten their financial sustainability, challenges that grew exponentially with the Great Recession. This article examines the impact of the Great Recession on the revenue and survival of CDC in Baltimore, Maryland; Cleveland, Ohio; and Detroit, Michigan. An analysis of financial data from the National Center for Charitable Statistics from 2004 to 2011 highlights issues of industry contraction, revenue concentration and loss, and CDC survival. Interviews and examination of multiple secondary sources of information on CDC activity and support networks in each city further our understanding of the financial results. We find that the CDC industry in all three cities was severely impacted by the Great Recession and that the CDC support networks in each city had a significant intervening effect on the ability of CDC to adapt to the fiscal and service pressures created by the recession. We discuss the implications of the shared trends and the city-specific dynamics for the role of CDC in neighborhood improvement in legacy cities. 相似文献

There is considerable debate about the impact of the 2006 NGO Law and related Kremlin policies on social organisations in Russia. This article uses interviews with members of organisations focusing on human rights, women, and youth to assess the effects of these policies on civil society. It finds that groups that are critical of the regime have been systematically pushed out of the public sphere and supplanted by groups that are either neutral to, or in favour of, the regime. This finding has implications for the future development of Russian civil society and demonstrates a way that non-democratic rule has been ‘upgraded’ in Russia. 相似文献

The objective of this paper is to contemplate changes in personnel system infrastructure required to implement Total Quality Management (TQM) in public organizations (perhaps formal organization in general). By infrastructure we mean systems such as those for the design of work and positions, rewards, performance appraisal, selection, etc. We introduced the subject by summarizing many of the concepts from the quality literature which express philosophy, structural aspects and practices. Even the industrial context in which TQM has flowered has not adapted significantly to implications of TQM philosophy and structure. Instead, traditional personnel management systems prevail with some concern for needed specia1 training, and anguish about negative effects of performance appraisal, some reward systems, and work standards. Because the government context is bound to present difficulties and pitfalls we summarized another body of literature, that of the reasons why the idea probably won't work in government. Ultimately, we get to the point of the essay: a discussion of contemplated types of personnel system changes that ought to support organizations operating in a quality mode. Changes are considered under the subjects of: work design, recruitment and selection, performance appraisal, training, compensation and labor-management relations. We conclude with a. brief case study on the Pacer Share Project. 相似文献
