This paper examines a number of demographic aspects in congressional districts and states that played important roles in a series of Congressional votes on environmental issues in 2000. These characteristics include urbanization or population density, education, income, race, and employment. Our findings are mixed. While we find some evidence (at least in Senate votes) that population density is a positive predictor of “pro-environment” votes, we also find that things commensurate with the Environmental Kuznets Curve such as income, education, and lifestyle also play an important role in environmental voting. 相似文献

The purpose of the pilot study was to examine the interrelationship between social support, risk-level, and safety actions for 2 groups of suicidal adolescents (50 attempters and 50 ideators), who had presented for an acute assessment at an outpatient mental health service. A social support model was proposed in which it was thought that information related to patients' social support would impact upon the types of risk-level and safety actions made by clinicians. Data was collected from a total of 100 patient files, utilizing the acute assessment reports (e.g., reports assessing risk of self-harm). Findings show that groups differed significantly on indices of negative support severity, positive support, and risk-level. Limited support was found for the proposed social support model. Limitations and implications for future research are discussed. 相似文献

This article reports an evaluation of a community intellectual disability offender service over the period from 1990 to 2001. Men who committed sex offenses or sexually abusive incidents (n = 106) and men who committed other types of offenses and serious incidents (n = 78) are compared on personal characteristics, referral sources, forensic details, and outcome up to 7 years after referral. The cohorts are older than one would expect from the criminology literature, and, at about 33%, the incidence of mental illness is consistent with some previous studies. A greater proportion of sex offenders had criminal justice involvement and a formal disposal from court. Fire raising was not overly represented as an offense. There was a higher rate of reoffending in the nonsexual cohort, which persisted up to 7 years. Investigating only reoffenders, there was a considerable amount of harm reduction recorded up to 7 years, statistically significant up to 5 years following initial referral. 相似文献

This paper addresses research in the life sciences, responsible for significant national expenditures for scientific investigations funded by both the federal government and industry. Our investigation examines faculty members' involvement with industry in entrepreneurial ways that is, involved in translating their research into potentially marketable knowledge or products. First, this study examines whether there are differences in entrepreneurial behaviour between clinical and non-clinical faculty in the life sciences with industry relationships, and, second, to discover any linkage between entrepreneurship and secrecy or productivity in different ways for clinical and non-clinical faculty. The study is based on survey responses of a national sample of 4,000 clinical and non-clinical life sciences faculty in 49 U.S. research universities. The results show non-clinical faculty as more involved at the back end. The more entrepreneurial end of commercialization while clinical faculty are involved at the back end. The more entrepreneurial faculty (non-clinical) are more likely to be secretive about their research. Clinical faculty are less likely to have been denied access to research results or products. Entrepreneurial faculty are not less productive in their faculty roles. This investigation is preliminary in that it addresses one large area of academic research but excludes fields with longer historical relationships with industry. 相似文献

A validation study was conducted to demonstrate that deoxyribonucleic acid (DNA) could be successfully extracted from human nail material and analyzed using short tandem repeat (STR) profiling and/or mitochondrial DNA (mtDNA) sequencing. This study involved the development of a DNA extraction protocol that includes a cleaning procedure designed to remove external contaminants (e.g., biological, chemical). This protocol was used to test human nail material that had been soaked in whole blood from a second donor and coated with gold-palladium to simulate scanning electron microscopic analysis. The results showed no indication of a mixture and were consistent with that of the nail donor. Fresh human nail material usually yielded both STR profiles and mtDNA sequence information; however, aged human nail material (approximately eight years old) yielded only mtDNA sequence information. Upon completion of the validation study, the extraction protocol was used for the analysis of a torn fingernail fragment recovered from the scene of a violent homicide in 1983. A partial STR profile and mtDNA sequence information indicated that the fingernail fragment was excluded as originating from the suspect and was, in fact, consistent with originating from one of the victims. 相似文献

This article explores Timor Leste's experience of reportingunder the reformed international human rights treaties reportingsystem during the period 2004–2007. Whilst consciousnesshas grown of the difficulties faced by states by the duplicationof treaty reporting processes and the resource burden representedby reporting, the reforms instituted to date have been comparativelyminor. Timor's experience with the new Common Core Document(CCD)/treaty-specificdocument format affirms that reporting serves useful purposes,particularly in stimulating human rights education initiatives,government/NGO collaboration and awareness of human rights gapsin practice. The reformed process highlights cross-cutting humanrights matters. Yet, significant challenges remain, particularlyfor developing, post-conflict states, before reporting willattain its desired potential of support for improved human rightspromotion and protection at the national level. The CCD itselfraises complex conceptual difficulties needing resolution. Thereremains a paucity of appropriate methodological tools to supportthe reporting process and facilitate the integration of humanrights and development goals. Further work is thus needed toshape a sustainable process for reporting. 相似文献
