Structural analysis of human rib fracture and implications for forensic interpretation

Patterns of rib fractures are of significant clinical and forensic interest. Linking patterns of rib fracture with specific physical events provides a foundation for understanding the nature of traumatic events that are associated with rib fracture in forensic contexts. In this study, isolated human ribs (n = 8) were end-loaded to failure to investigate: (i) local deformations (bone strain) prior to and during structural failure, (ii) location of ultimate failure, and (iii) fracture mode. Structural properties of ribs were used to calculate theoretical stresses to determine whether such calculations could be used to predict site of fracture. Ribs fractured on the sternal side of midshaft in all experiments, but mode of failure varied with transverse, buckle, spiral, and "butterfly" fractures observed. Comparison of calculated stress with observed strain values suggest that experimental, rather than theoretical, approaches will be most productive in furthering understanding rib fracture in forensic contexts.     

What Does Corruption Mean in a Democracy?

Despite a growing interest in corruption, the topic has been absent from democratic theory. The reason is not a lack of normative issues, but rather missing links between the concepts of corruption and democracy. With few exceptions, political corruption has been conceived as departures by public officials from public rules, norms, and laws for the sake of private gain. Such a conception works well within bureaucratic contexts with well-defined offices, purposes, and norms of conduct. But it inadequately identifies corruption in political contexts, that is, the processes of contestation through which common purposes, norms, and rules are created. Corruption in a democracy, I argue, involves duplicitous violations of the democratic norm of inclusion. Such a conception encompasses the standard conception while complementing it with attention to the dynamics of inclusion and exclusion within democratic politics. By distinguishing the meanings of inclusion and exclusion within the many institutions, spheres, and associations that constitute contemporary democracies, I provide a democratic conception of corruption with a number of implications. The most important of these is that corruption in a democracy usually indicates a deficit of democracy.
