Exploring the Drugs-Homicide Connection
Although research generally assumes a close relationship between drugs and violence, very little is known about the many different roles drugs can play in criminal events. Drug related as an event classification scheme is relatively common in homicide research, as well as other areas of inquiry, and is usually understood to be an important component in the causal processes of criminal events. Yet such classification schemes often suggest a simple, unidimensional construct. In reality, drug-related crimes are com-plex events. The purpose of this researchwas first to disaggregate the concept of drug-related homicide by providing an event classification scheme that conceptualizes the diverse roles drugs play in drug-related events.Acategorical coding scheme is presented that is similar to that proposed by Goldstein (1995) and later tested by Brownstein and colleagues (Brownstein & Goldstein, 1990; Brownstein, Baxi, Goldstein, & Ryan, 1992) that specifies three distinct types of homicide events. Included among these are (a) events that involved no evidence of illicit drugs associated with the homicide event, (b) those that involved the presence of drugs or drug use at the scene as well as events where either the victim and/or offender were buying or selling drugs (we term this peripherally drug-related homicides), and (c) events where the sale or use of drugswas the motivating feature of the homicide event. In some situations, there may be overlap between categories b and c; however, category c is distinct in that it includes features of motivation. The second purpose was to determine the relative importance of various situational and contextual characteristics of homicide events in understanding different types of drug-related events. Delineating these features will be an important step in filling in the gaps of knowledge about the assumed relationship between drugs and violence

Evaluation of a Comprehensive Approach to Reducing Gun Violence in Detroit
Increasingly criminal justice agencies are integrating “data based” approaches into their operational strategies. This “new” model of criminal justice suggests that analysis of data on recent crime and violence incidents can lead to a more focused and targeted effort than previous enforcement efforts. Through such efforts, individuals, groups, and locations that exhibit a high level of gun violence within a limited geographic area are identified and a variety of intervention are then implemented. These interventions typically include both enforcement as well as offender focused interventions. These efforts differ from prior enforcement strategies in that they emphasize the integration of a problem analysis component in which data analysis is used to identify the patterns of gun violence in a small target area and enforcement resources are concentrated in this area.
However, this approach also differs from previous “crackdown” enforcement strategies in that there are also community and offender intervention components that are integral to this model. The community component seeks to identify ways in which the community can be involved in working with law enforcement to reduce gun violence in this area. This is often through increased community meetings, and establishing more frequent and effective means of communication between the community and local law enforcement.
In addition, the enforcement strategies used in this model are data and intelligence driven. As such they are focused on identifying the most problematic locations, groups and individuals that are most responsible for gun violence in this community.
This report documents the implementation and outcomes of the implementation of Project Safe Neighborhoods in one of the jurisdictions in which this model was first implemented
Compressible flow structures interaction with a two-dimensional ejector: a cold-flow study
An experimental study has been conducted to examine the interaction of compressible flow structures such as
shocks and vortices with a two-dimensional ejector geometry using a shock-tube facility. Three diaphragm pressure
ratios ofP4
=P1 = 4, 8, and 12 have been employed, whereP4
is the driver gas pressure andP1
is the pressure within
the driven compartment of the shock tube. These lead to incident shock Mach numbers of Ms = 1:34, 1.54, and 1.66,
respectively. The length of the driver section of the shock tube was 700 mm. Air was used for both the driver and
driven gases. High-speed shadowgraphy was employed to visualize the induced flowfield. Pressure measurements
were taken at different locations along the test section to study theflow quantitatively. The induced flow is unsteady
and dependent on the degree of compressibility of the initial shock wave generated by the rupture of the diaphragm
The Cost-Effectiveness of Continuous Commissioning® Over the Past Ten Years
Continuous Commissioning® data including savings, costs, and implemented measures from over 60 buildings and sites commissioned by staff from the Energy Systems Laboratory at Texas A&M University are presented. Measured annual whole building data is included and is used to calculate indicators describing energy savings, commissioning cost, and the relationship between the two. The measures are organized by component and type and analyzed for frequency of implementation. The average unit area savings for the data set is 5.52/(m2a)) with an average annual energy cost savings of 14%. The average cost of commissioning is 4.60/(m2a)) resulting in an average simple payback of 1.6 years. Just over half of the measures implemented are related to air handling and distribution and 13% of the total number of measures implemented are advanced resets of air side systems. Overall, the analysis reinforces previous studies demonstrating the effectiveness of Continuous Commissioning®
Formative Research on Perceptions of Biobanking: What Community Members Think
Preparing healthy community members with timely communications prior to engaging them in a request to donate biospecimens promises to improve the experience of biobanking participation. To this end, a qualitative study was conducted to assess community member knowledge, attitudes, beliefs, and informational needs about cancer-related biospecimen collection in a large metropolitan area in southwest Florida. The study utilized purposive sampling techniques to recruit a total of 95 participants to participate in 12 focus groups, segmented by race/ethnicity and language preference (mixed race, African American only, and Spanish speaking) and age (18–29, 30–54, and 55 and older). Focus group interviews were analyzed using content analysis to identify emergent themes. Overall, participants in the 30 years and older groups were favorable toward participating in biobanking if their concerns were addressed, such as confidentiality and consent issues, in contrast to participants aged 18–29 who were more skeptical. For all participants, the desire to participate in research that seeks new cancer treatments outweighed mistrust. Moreover, many cited the potential scientific benefit for future generations as a primary motivator. Finally, in some groups a therapeutic misconception was expressed, where participants expressed a willingness to forego confidentiality of their health status in exchange for therapeutic benefit. This study contributes to the literature on community perceptions of the benefits and barriers of biobanking and adds to the development of meaningful education communication priming tools to advance understandings about biobanking
Standard set of health outcome measures for older persons
Background: The International Consortium for Health Outcomes Measurement (ICHOM) was founded in 2012 to propose consensus-based measurement tools and documentation for different conditions and populations.This article describes how the ICHOM Older Person Working Group followed a consensus-driven modified Delphi technique to develop multiple global outcome measures in older persons. The standard set of outcome measures developed by this group will support the ability of healthcare systems to improve their care pathways and quality of care. An additional benefit will be the opportunity to compare variations in outcomes which encourages and supports learning between different health care systems that drives quality improvement. These outcome measures were not developed for use in research. They are aimed at non researchers in healthcare provision and those who pay for these services. Methods: A modified Delphi technique utilising a value based healthcare framework was applied by an international panel to arrive at consensus decisions.To inform the panel meetings, information was sought from literature reviews, longitudinal ageing surveys and a focus group. Results: The outcome measures developed and recommended were participation in decision making, autonomy and control, mood and emotional health, loneliness and isolation, pain, activities of daily living, frailty, time spent in hospital, overall survival, carer burden, polypharmacy, falls and place of death mapped to a three tier value based healthcare framework. Conclusions: The first global health standard set of outcome measures in older persons has been developed to enable health care systems improve the quality of care provided to older persons
Universal cures for idiosyncratic illnesses: a genealogy of therapeutic reasoning in the mental health field
Over the past decades, there has been a significant increase in prescriptions of psychotropic drugs for mental disorders. So far, most of the explanations of the phenomenon have focused on the process of medicalization, but little attention has been cast towards physicians' day-to-day clinical reasoning, and the way it affects therapeutic decision-making. This article addresses the complex relationship between aetiology, diagnosis and drug treatment by examining the style of reasoning underlying prescribing practices through an historical lens. A genealogy of contemporary prescribing practices is proposed, that draws significant comparisons between 19th-century medicine and modern psychiatry. Tensions between specific, standardized cures and specific, idiosyncratic patients have been historically at play in clinical reasoning - and still are today. This inquiry into the epistemological foundations of contemporary drug prescription reveals an underlying search for scientific legitimacy
