Validation of tool mark analysis of cut costal cartilage

This study was designed to establish the potential error rate associated with the generally accepted method of tool mark analysis of cut marks in costal cartilage. Three knives with different blade types were used to make experimental cut marks in costal cartilage of pigs. Each cut surface was cast, and each cast was examined by three analysts working independently. The presence of striations, regularity of striations, and presence of a primary and secondary striation pattern were recorded for each cast. The distance between each striation was measured. The results showed that striations were not consistently impressed on the cut surface by the blade's cutting edge. Also, blade type classification by the presence or absence of striations led to a 65% misclassification rate. Use of the classification tree and cross-validation methods and inclusion of the mean interstriation distance decreased the error rate to c. 50%.     

Expanding dependent coverage for young adults: lessons from state initiatives

The Patient Protection and Affordable Care Act (ACA) requires that adults up to age twenty-six be permitted to enroll as dependents on their parents' health plans. This article examines the experiences of states that enacted dependent expansion laws. Drawing on public information from thirty-one enacting states and case studies of four diverse reform states, it derives lessons that are pertinent to the implementation of this ACA provision. Dependent coverage laws vary across the states, but most impose residency, marital status, and other restrictions. The federal Employee Retirement Income Security Act further limits the reach of state laws. Eligibility for expanded coverage under the ACA is much broader. Rules in some states requiring or allowing separate premiums for adult dependents may also discourage enrollment compared with rules in other states (and the ACA), where these costs must be factored into family premiums. Business opposition in some states led to more restrictive regulations, especially for how premiums are charged, which in turn raised greater implementation challenges. Case study states did not report substantial young adult dependent coverage take-up, but early enrollment experience under ACA appears to be more positive. Long-term questions remain about the implications of this policy for risk pooling and the distribution of premium costs.     

The Messenger Overwhelming the Message: Ideological Cues and Perceptions of Bias in Television News

Survey research has demonstrated that citizens perceive ideological bias in television news, specifically with regard to CNN and Fox News Channel (FNC), which allegedly represent the liberal and conservative viewpoint, respectively. In this paper I argue that attaching the CNN and FNC labels to news stories sends an ideological cue to the viewer regarding the content of the story. Utilizing an experimental design that allows manipulation of the network attribution of actual FNC and CNN content, I am able to demonstrate that the CNN and FNC labels function as ideological signals to the viewer, with this signal being most pronounced among ideologues whose views are supposedly at odds with those attributed to the network.

Governance is where you find it

The concept of governance is used frequently and in a variety of different ways. This article discusses Mark Bevir’s use of an interpretative approach to governance and its implications for understanding better how we govern. This approach has particular relevance to democratic forms of governance, and to the use of deliberative and direct forms of democracy.     

Non-Contingent Success Reduces People’s Desire for Processes that Adhere to Principles of Fairness

A central tenet of justice theory and research is that people prefer decisions to be made with processes that adhere to principles of fairness. The present research identified a boundary condition for this general tendency. Across three studies, we found that people who experienced non-contingent success had less of a desire for fair processes relative to their counterparts who experienced contingent success. Furthermore, results attributable to other independent variables, namely regulatory focus in Study 2 and self-affirmation in Study 3, shed light on the underlying mechanism: people experience non-contingent success as self-threatening and lower their desire for processes that adhere to fairness in the service of protecting themselves against the threat. Theoretical implications are discussed as are limitations of the studies and suggestions for future research.     

The Political Resurrection of Russian Governors

Elections for all 83 Russian governors were reinstated in Russia in 2012, seven years after they had been suspended. The democratic reform coincided with renewed political activism in Russia since December 2011, but the reform was as much a belated recognition of the shortcomings and failures from appointing Russian governors. Pragmatic necessity and not democratic conversion was the determining factor. Based on the first elections in October 2012, the reform will have only a limited effect over the next few years on democratic change in Russia, at most placating liberal and regional demands while consolidating personal rule under Putin.
