Benefit adequacy in state workers' compensation programs

This article summarizes several different methods used to measure the adequacy of wage replacement in state workers' compensation systems in the United States. Empirical research casts serious doubt on benefit adequacy, especially in the case of more serious disabilities.     

Myxoid heart disease: A review with special emphasis on sudden cardiac death

Myxoid heart disease (MHD), more commonly known as mitral valve prolapse, is a very common caridac abnormality affecting 5–10% of the general population. This article reviews the history, symptoms, physical findings, pathology, associated conditions and complications of this entity. Special emphasis is given to sudden cardiac death, which occurs as a result of acute heart failure or due to a fatal arrhythmia. Theories regarding the origin of the arrhythmias are discussed. Once the origin is known, those at risk for this devastating complication can be identified and perhaps a preventative therapeutic regimen developed.     

Emerging powers and the responsibility to protect: non-linear norm dynamics in complex international society

The perceived clash of norms associated with the emergence of rising powers is nowhere more pronounced than in relation to the responsibility to protect (RtoP). However, attempts to explain rising powers’ engagement with norms such as the RtoP are often limited and limiting in what they can tell us. Orthodox models portray predominantly linear and diffusionist logics of norm evolution that underplay the complex interaction implicit in unpredictable outcomes at the systemic level. This article identifies a range of factors that drive participation (or generate hesitation) amongst emerging powers in the development and application of the RtoP. It proceeds to illustrate how changes in normative behaviour emanate from top-down and bottom-up processes as well as the feedback between them. It argues that norm evolution is consequently a unique and emergent outcome of complex international society and therefore argues for using complexity thinking as a heuristic to augment current models and explanations of the evolution of norms in the international system.     

Predictions put into practice: a quasi-experimental evaluation of Chicago’s predictive policing pilot

Objectives

In 2013, the Chicago Police Department conducted a pilot of a predictive policing program designed to reduce gun violence. The program included development of a Strategic Subjects List (SSL) of people estimated to be at highest risk of gun violence who were then referred to local police commanders for a preventive intervention. The purpose of this study is to identify the impact of the pilot on individual- and city-level gun violence, and to test possible drivers of results.

Methods

The SSL consisted of 426 people estimated to be at highest risk of gun violence. We used ARIMA models to estimate impacts on city-level homicide trends, and propensity score matching to estimate the effects of being placed on the list on five measures related to gun violence. A mediation analysis and interviews with police leadership and COMPSTAT meeting observations help understand what is driving results.

Results

Individuals on the SSL are not more or less likely to become a victim of a homicide or shooting than the comparison group, and this is further supported by city-level analysis. The treated group is more likely to be arrested for a shooting.

Conclusions

It is not clear how the predictions should be used in the field. One potential reason why being placed on the list resulted in an increased chance of being arrested for a shooting is that some officers may have used the list as leads to closing shooting cases. The results provide for a discussion about the future of individual-based predictive policing programs.
