The Concentration and Stability of Drug Activity in Seattle,Washington Using Police and Emergency Medical Services Data

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.

     

Assessing Functional Impairment in ADHD: Concerns for Validity of Self-Report

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.     

Engaging with Asia: the Chifley Government and the New Delhi Conferences of 1947 and 1949

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.     

An evaluation of the effectiveness of positive behavioural support within a medium secure mental health forensic service

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.     

Trends in police research: a cross-sectional analysis of the 2010-2014 literature

ABSTRACT

This review provides a cross-sectional analysis of the police literature for years 2000 to 2014. It represents the ninth special feature review of police research published in Police Practice and Research: An International Journal. The study reports on trends over time in police literature according to substantive categories, publication medium, and methodological typology. The study also relies on findings from prior police research reviews as a basis for a discussion of the long-term patterns of police research over time from 2000 to 2014. A topically organized bibliography of the 2010 to 2014 police literature reviewed is also provided.     

Forensic Case Reports Presenting Immersion Pulmonary Edema as a Differential Diagnosis in Fatal Diving Accidents

Immersion Pulmonary Edema (IPE) reduces the transport of gases over the respiratory membrane due to edema in the interstitium and respiratory zones. IPE has previously been described in both swimmers and divers, with a few known fatal cases. We have reviewed 42 SCUBA and snorkeling‐related drowning deaths, and through a thorough analysis of each case, including both diving physiology and forensic pathology, we present IPE as a differential diagnosis to drowning in four cases. Our findings propose that; absence of watery content in the stomach and conducting airways, and liquid filled lungs without hyperexpansion, may be compatible with IPE. We suggest that IPE should be considered in cases where witness testimony reveals; no obvious signs of aspiration and rapid respiratory deterioration despite continuous breathing through an appropriate air source. The diagnosis should be based on the overall impression, including both the autopsy findings and the circumstances regarding the accident.     

Police Bias,Social Identity,and Minority Groups: A Social Psychological Understanding of Cooperation with Police

The present study uses Social Identity Theory as a framework to investigate the collective effects of perceived police bias, ethnicity and self-identification with different groups on respondents’ intentions to cooperate with police in general crime control efforts and in counter-terrorism policing. Drawing on survey data collected from 1,272 individuals from three ethnic minority backgrounds in Australia, the present study reports findings including: (1) significant and large direct positive associations between superordinate identity and willingness to cooperate with police, (2) small-to-moderate significant associations between perceived police bias and cooperation with police (positive for Vietnamese subsample; negative for Indian and Arab subsamples), and (3) significant interaction patterns between subordinate identity, perceived police bias, and ethnicity. Findings are discussed with respect to community-engaged prevention and prejudice reduction.
