WinID2 versus CAPMI4: two computer-assisted dental identification systems

Disasters produce victims that require identification. Comparing antemortem and postmortem dental records provides an important means of identification. Computers have assisted this process. Currently, the principal computer programs are CAPMI4 and WinID2. The present study compared these programs on a sample of 100 simulated victims and 105 simulated postmortem fragments. CAPMI4 provided 48 correct matches and WinID2 provided 71 correct matches. In addition, comparisons were made within WinID2 to determine which of its three dental data sets was the most successful for suggesting correct matches.     

Evolving structure of governments: Portfolio adoption across the Canadian provinces from 1867–2012

Based on work by Moon and Sayers on the assignment of ministerial portfolios in Australia, we use a new dataset on portfolio adoption across all ten Canadian provinces and the federal government from 1867–2012. This data set when analyzed shows four distinct patterns of portfolio adoption that point to key motivations behind the development of new portfolios. We show that much of the common wisdom fails to explain portfolio creation but that patterns of development may be better explained by a new typology. The work attempts to fill a gap in the understudied area of Canadian ministerial portfolios and comparative provincial politics.     

The Process of Leaving an Abusive Relationship: The Role of Risk Assessments and Decision-Certainty

Seventy female residents of an urban domestic violence shelter were interviewed to examine a series of hypotheses concerning two factors relevant to the process of leaving an abusive relationship: risk assessments and decision-certainty. Participants' subjective estimates of their own risk of returning to the batterer were examined relative to their perceptions of the likelihood that most battered women will return to the batterer, their certainty regarding the decision to leave the batterer, and their status on known risk factors for returning to an abusive relationship. As hypothesized, battered women's perceptions of personal risk for returning to the batterer were biased by unrealistic optimism; specifically, personal risk was estimated as significantly lower than the risk of most battered women and was not correlated with actual risk factors. Further, the magnitude of the optimistic bias was significantly greater among women expressing high certainty about their decision to leave than among women who expressed less certainty. The clinical implications of these findings are discussed.     

Indicators of political development

Development implies goals and the positing of goals requires values. Economists have generally agreed that the increase of wealth (or perhaps welfare) is the proper object of economic development. Political scientists, probably happily, have no similar agreement in regard to the appropriate goal for political development. Moreover, it is doubtful that the various aspects of political change are located along a single continuum. This is an empirical question but investigation ought to begin at least with provision for an n‐dimensional space. Finally, political scientists should concentrate on political change that has too often been neglected in favour of economic and purely social change.
