Fracture Characteristics of Entrapped Head Impacts Versus Controlled Head Drops in Infant Porcine Specimens,,

In many forensic cases, the job of forensic pathologists and anthropologists is to determine whether pediatric death is due to an abusive act or an accidental fall. The goal of this study was to compare the cranial fracture patterns generated on the parietal bone of a developing, infant porcine (pig, Sus scrofa) model by a controlled energy head drop onto a plate versus previous data generated by blunt force impact at the same energy onto the head constrained to a plate. The results showed that blunt force impacts on a head constrained to a rigid plate produces more fracture, but the same general pattern, as that for a head dropped onto the plate with the same level of impact energy. The study suggests that head constraint may be an important factor to consider in the evaluation of death causation for blunt force impacts to the pediatric skull.     

Application of Random Match Probability Calculations to Mixed STR Profiles

Mixed DNA profiles are being encountered more frequently as laboratories analyze increasing amounts of touch evidence. If it is determined that an individual could be a possible contributor to the mixture, it is necessary to perform a statistical analysis to allow an assignment of weight to the evidence. Currently, the combined probability of inclusion (CPI) and the likelihood ratio (LR) are the most commonly used methods to perform the statistical analysis. A third method, random match probability (RMP), is available. This article compares the advantages and disadvantages of the CPI and LR methods to the RMP method. We demonstrate that although the LR method is still considered the most powerful of the binary methods, the RMP and LR methods make similar use of the observed data such as peak height, assumed number of contributors, and known contributors where the CPI calculation tends to waste information and be less informative.     

The Displaying of Yard Signs as a Form of Political Participation

Despite the ubiquity of yard signs, little is known about how and why individuals display them. Using two original studies of the 2008 presidential race, along with American National Election Study data, we address three points pertaining to this understudied form of political participation. First, what are the correlates of the individuals and households that display signs? Second, what motivates such displays, and to what extent do those motives reflect expressive and communicative desires? Finally, how do individuals obtain signs, and do individuals—rather than parties or candidates—play a role in spreading signs throughout neighborhoods? Our findings suggest that the dissemination of yard signs is not merely a top–down process driven by campaign professionals, but a genuine participatory act that is fueled by individual initiative and social networking.     

Rivalry and superior dispatch: an?analysis of competing courts in medieval and early modern England

In most areas, economists look to competition to align incentives, but not so with courts. Many believe that competition enables plaintiff forum shopping, but Adam Smith praised rivalry among courts. This article describes the courts when the common law developed. In many areas of law, courts were monopolized and imposed decisions on unwilling participants. In other areas, however, large degrees of competition and consent were present. In many areas, local, hundred, manorial, county, ecclesiastical, law merchant, chancery, and common law courts competed for customers. When parties had a choice, courts needed to provide a forum that was ex ante value maximizing.
