In west-central Alberta, Canada, an ambitious collaborative conservation program for grizzly bears began in 1999, after extensive
controversy over the Cheviot coal mine project and successful negotiation of a unique federal–provincial strategic framework
for grizzly bear conservation. Unfortunately that program was effectively terminated without any substantive implementation
of its research findings. The regional ecosystem approach for conserving grizzlies in the Foothills Model Forest originated
in federal and provincial legislative processes but proved vulnerable to shifting goals and containment by a single powerful
participant. This case study’s results demonstrate vulnerabilities of the ecosystem management approach to conserving large
carnivores. To enable other such conservation efforts to achieve their goals, we recommend supporting emergent small-scale
initiatives and designing collaborative institutions that limit the potential for containment of decision processes. 相似文献

The analysis of motor oils has wide applications in the forensic science field from comparing lubricants transferred between an automobile and a victim or crime scene to differentiating the compositions of plastic explosives. In this study, 40 unused motor oils were analyzed and compared by high-temperature gas chromatography-mass spectrometry to determine the potential for oil individualization. Oil samples were also collected from the crankcase dipsticks of 30 cars. Twenty-six of these oils could be differentiated from each other based on visual comparisons of the unresolved envelope (baseline rise due to incomplete separation) and the resolved hydrocarbons in the raw total ion chromatograms (TICs) and smoothed TIC data. Four of these oils were analyzed as unknowns and were correctly related to the corresponding vehicle. The use of extracted ion profiles (EIPs) was explored as a means to further discriminate between the indistinct samples based on the polycyclic aromatic hydrocarbon (PAH) content. The research discussed in this paper demonstrated that differentiation of motor oils was possible by examining the TIC, smoothed TIC, and EIP data. 相似文献

Purpose
Sexual aggression on college campuses has received a great deal of research attention. Little criminological theory, however, has systematically linked individual-level risk factors for sexual aggression with broader societal factors like patriarchy. DeKeseredy and Schwartz (1993) proposed that societal patriarchy is translated into individual attitudes of male sexual proprietariness and entitlement, which provide motivation and justifications for sexual violence.Methods
This study explored the concept of entitlement through various measures and demonstrated the utility of the concept by linking it with other theoretically-relevant variables, including self-control, sexual partners, use of pornography, adversarial sexual beliefs, and rape myth adherence.Results
Entitlement was significantly correlated with theoretically-relevant variables in the expected directions. Additionally, entitlement was able to distinguish sexually aggressive and nonaggressive men. Multivariate models provided support for the theoretical assertion that entitlement fosters rape-supportive attitudes and behaviors, which in turn was related to sexual aggression.Conclusions
Entitlement is an important concept in understanding sexual aggression, and the causal relationships implied by theory should be explored further in future research. Implications and directions for future research and theory are discussed. 相似文献207.
Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome
studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing
child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management,
self control, stimulus control, communication and child management skills training exercises, and financial management components.
Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated
by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her
responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental
control and follow-up data collection) of this case example are discussed in light of these results. 相似文献

This study asked whether latent class modeling methods and multiple ratings of the same cases might permit quantification
of the accuracy of forensic assessments. Five evaluators examined 156 redacted court reports concerning criminal defendants
who had undergone hospitalization for evaluation or restoration of their adjudicative competence. Evaluators rated each defendant’s
Dusky-defined competence to stand trial on a five-point scale as well as each defendant’s understanding of, appreciation of, and
reasoning about criminal proceedings. Having multiple ratings per defendant made it possible to estimate accuracy parameters
using maximum likelihood and Bayesian approaches, despite the absence of any “gold standard” for the defendants’ true competence
status. Evaluators appeared to be very accurate, though this finding should be viewed with caution. 相似文献

The plant Catha edulis, known more commonly as khat, has been consumed for centuries for its stimulatory effects, especially by people living in East Africa. As people from Somalia, Ethiopia and other East African countries have migrated to Australia, they have brought with them the practice of chewing khat. This article examines the claims made about the effects of khat on health and wellbeing and explores the approaches to the regulation of khat in Australia and overseas. The article concludes with a discussion of some of the concerns associated with current regulatory approaches and makes some suggestions for reform. 相似文献
