The diagnosis of diffuse axonal injury in routine autopsy practice

A 40-year-old pedestrian was involved in a road traffic accident. He lost consciousness immediately and remained comatose for 6 months until he died of a bronchopneumonia. Examination of the fixed brain revealed the late results of diffuse axonal injury. Not all the features were readily visible macroscopically, but required a limited number of histological sections from readily predictable sites for demonstration. Special stains played only a confirmatory role. This case illustrates some of the problems in diagnosing one of the commoner patterns of brain damage in head injury, and shows how the problem may best be approached in practice.     

Can Social Media Predict Election Results? Evidence From New Zealand

The importance of social media for election campaigning has received a lot of attention recently. Using data from the 2011 New Zealand general election and the size of candidates’ social media networks on Facebook and Twitter, we investigate whether social media is associated with election votes and probability of election success. Overall, our results suggest that there is a statistically significant relationship between the size of online social networks and election voting and election results. However, the size of the effect is small and it appears that social media presence is therefore only predictive in closely contested elections.     

Individual neighborhood attachment and perceptions of neighborhood safety

Macrostructural research in the social disorganization tradition assumes neighborhood structure dictates individual behavior. The current research explores the opposite perspective to determine whether individual attachment to the neighborhood influences perceptions of neighborhood safety. Using the Chicago Metropolitan Area Survey, the results show that loners, persons wishing to move, and renters perceive their neighborhoods as being less safe than attached residents. Implications for future research are offered. Data for this study were made available by the Inter-University Consortium for Political and Social Research.
