Research partnerships between anthropologists and the individuals or groups with whom they work may take a variety of forms. This paper examines four partnerships which evolved during the research project, “The Place of Alcohol in the Lives of New Zealand Women.” These partnerships were between anthropologists and Samoan, Cook Islands, Maori, and Lesbian women living in New Zealand. The strengths and weaknesses of each relationship are evaluated in an attempt to evolve a range of successful models of research partnership.  相似文献

In the past three years, new laws have been introduced in four Australian states designed to prevent criminal conspiracies by outlaw motorcycle gang (OMG) members and to disrupt the criminal activities of these gangs. The Australian laws push the boundaries previously set in similar laws in other jurisdictions, in that controls can be imposed because of membership of an organization perceived as a threat by the state. The laws constitute a pre-emptive strike against OMGs. However, there are very real issues about their likely effectiveness, given research suggesting that the primary structures targeted in this legislation, the clubs, are not necessarily the ones that OMG members use to conduct their criminal business. This article explores these issues, and suggests that the reaction of OMGs to this legislation may provide important information about OMG adaptiveness and resilience.  相似文献

Young children (4- to 7-years old; N = 59) and adults (N = 53) were shown a series of targets that were either familiar (i.e., popular cartoon characters) or unfamiliar (unknown human faces) to assess whether children’s false positive responding with target-absent lineups is driven by social factors to a greater degree than cognitive factors. Although children were able to produce correct identification rates with virtually 100% accuracy for the cartoon characters, they produced a significantly lower correct rejection rate compared to adults. Children also produced a significantly lower correct rejection rate for the human faces compared to adults. These data are discussed for understanding children’s identification evidence.  相似文献

Children’s (N = 89) identification accuracy was examined as a function of lineup size. Participants (8–13 years) viewed a videotaped staged event, described what was witnessed and then were presented with either a target-present or—absent lineup containing 6 versus 12 lineup members. The elimination lineup procedure (Pozzulo and Lindsay J Appl Psychol 38: 2195–2209 1999) was used to present lineups. No significant differences in correct identification rates were found across the target-present sized lineups. In addition, the target was likely to “survive” at a comparable rate regardless of lineup size. Moreover, there was no significant difference in correct rejection rate as a function of lineup size. The non significance of these data are critical given that most research with child witnesses uses 6-person lineups whereas in many real world contexts larger sized lineups are used (e.g., 12-person in Canada).  相似文献

Objectives

Prior research demonstrates that crime is highly concentrated at place and that these concentrations are stable from year to year, highlighting the importance of place to crime control and prevention. A potential limitation is that most studies only use one data source to diagnose these patterns. The present study uses data from both police and emergency medical services (EMS) to explore the spatial concentration and stability of drug activity in Seattle, Washington from 2009 to 2014.

Methods

We use concentration graphs and group-based trajectory analysis to examine concentration and stability of calls related to drug activity in both data sources separately and combined. Additionally, we employ Andresen’s S-Index to determine the similarity of concentration within the SPD data, the EMS data and the combined data year to year as well as the degree of co-location between the SPD and EMS data during the study period.

Results

We find a high degree of concentration and group-based stability for both SPD and EMS drug calls across all street segments in Seattle. Conversely, we find only moderate local geographic stability of drug use across street segments as indicated by each of the data sources over the study period. Last, we find the spatial patterns in drug use as indicated by each data source are significantly different each year.

Conclusions

At the same time these findings provide support for the law of crime concentration, they also raise questions about local stability patterns. Additionally, they highlight the importance of expanding inquiries of crime and place research into new data sources. Our results serve to reinforce the importance of multiple data sets in quantifying, understanding, and responding to the drug problem in Seattle.

Comprehensive diagnostic assessment of attention deficit hyperactivity disorder (ADHD) should include consideration of degree of impairment, and documentation of impairment is necessary to make service and accommodation determinations. While there has been increasing use of self-report as a way to document impairment, self-reported impairment could be just as vulnerable to invalid report as self-reported symptoms. We examined the influence of invalid self-report and invalid performance on report of functional impairment in a sample of 49 adults referred for evaluation for ADHD and/or learning disorder concerns. Overall, 26–59% of participants referred for evaluation endorsed at least moderate levels of impairment in the domains of understanding and communicating, household, and school/work. Individuals with evidence of invalid self-report of ADHD symptoms endorsed significantly higher levels of disability/impairment on the WHODAS, particularly in the domains of understanding and communicating, household, school/work, and participation in society. Further, individuals who failed a measure of performance validity reported significantly higher levels of impairment/disability, particularly in the domains of understanding and communicating, school/work, and participation in society. Results emphasize the need to assess for validity of self-report and performance in ADHD assessment. Since self-report of impairment may be suspect, clinicians should include data such as school records, past performance on high-stakes standardized testing, evidence of prior accommodations, and collateral reports before making diagnoses and/or recommendations regarding treatment or academic/workplace accommodations.  相似文献

This article is a study of the Chifley government's foreign policy towards Asia, in particular India and Indonesia, as evidenced by Australia's attendance at the 1947 Asian Relations Conference and the 1949 New Delhi Conference on the Indonesian‐Dutch conflict. Australia's presence at these two conferences provides an ideal opportunity to examine the Chifley government's response to the momentous changes that occurred in post‐war Asia as a result of the dismantling of the European colonial world order. Through detailed examination of the archival material and contemporary accounts generated from Australia's involvement in the New Delhi conferences, this article will argue that despite significant political constraints, the Chifley government did adopt a distinctive and innovative policy towards the emergent nations of Asia in the immediate post‐war years.  相似文献

A number of recent influential reports recommend the use of proactive and preventative approaches such as Positive Behavioural Support (PBS) in the management of challenging behaviours. Although evidence supporting the use of PBS is mainly drawn from studies of learning disability and child populations, it is recognised that PBS could have a much wider utility. In this study, PBS was implemented in a medium secure forensic mental health service, a novel context. Impact was evaluated using an adapted version of the Checklist of Challenging Behaviour at baseline and then at 3 monthly intervals for a year. Significant reductions were observed in aggression frequency, management difficulty and severity and other challenging behaviour frequency and management difficulty. Reductions in challenging behaviour were still evident after six months for the full group and twelve months for the sub-group with the exception of other challenging behaviour management difficulty. In contrast, no such significant differences were found for a control group. This study indicated that PBS was an effective intervention in the management of challenging behaviour in this forensic mental health context.  相似文献
