Characterization of the triacylglycerol crystal formation in adipose tissue during a vehicle collision

The unusual appearance of crystalline fat structures was observed during the postmortem examination of a motor vehicle accident victim. The crystal structures were characterized using Fourier transform infrared spectroscopy and x-ray diffractometry. The structures were found to be made of triacylglycerols, a dominant lipid structure found in human adipose tissue, capable of forming various polymorphic structures. The morphology of the crystalline material was found using both techniques to be predominantly the beta' form of triacylglycerols. The accelerated growth of such triacylglycerol morphology has been observed as a result of shear stresses in other studies involving edible fats. As a result of the findings of this study, it is proposed that increased shear forces may be responsible for the formation of the unusual fat structure found in the victim. An understanding of the effect of forces on the structure of body fat in high-impact collisions can potentially assist in verifying a high-velocity impact.     

Predicting Initiator and Near Repeat Events in Spatiotemporal Crime Patterns: An Analysis of Residential Burglary and Motor Vehicle Theft

Near repeat analysis has been increasingly used to measure the spatiotemporal clustering of crime in contemporary criminology. Despite its predictive capacity, the typically short time frame of near repeat crime patterns can negatively affect the crime prevention utility of near repeat analysis. Thus, recent research has argued for a greater understanding of the types of places that are most likely to generate near repeat crime patterns. The current study contributes to the literature through a spatiotemporal analysis of residential burglary and motor vehicle theft in Indianapolis, IN. Near Repeat analyses were followed by multinomial logistic regression models to identify covariates related to the occurrence of initiator (the first event in a near repeat chain) and near repeat (the subsequent event in a near repeat chain) events. The overall findings provide additional support for the argument that neighborhood context can influence the formation and context of spatiotemporal crime patterns.

Party presidentialization in post-Suharto Indonesia

ABSTRACT

Indonesia presents an extremely rare quasi-experimental research case: the constitutional reforms and the transition to full presidentialism have effected a presidentialization of political parties that is largely in line with the changes predicted by the model of Samuels and Shugart [2010. Presidents, parties and prime ministers: How separation of powers affects party organization and behaviour. Cambridge: Cambridge University Press]. Especially the rise of the new president and his difficult relationship with his own party are testimony to this. But a closer look reveals that the model has to be adapted to Indonesian politics. Presidents have tools to forge grand coalitions and to overcome the dualism to an extent. The size and history of political parties as well as wider socio-economic changes, that is an increasing oligarchization of party organization, have to be considered. Moreover, highly personalized vehicle parties serving the interests of a presidential candidate have emerged. It follows that institutional and structural incentives combined have produced a party system consisting of different party types.
