Religion, government coalitions, and terrorism

When ethnic minority parties are excluded from government coalitions, are group attributes such as religion related to the groups' use of political violence? We argue that extremist factions within minority groups make use of divergence in religion to mobilize support for violent action when the group is excluded from government. Thus, we posit that while religion per se is not a source of violence, extremist elements of ethnic minorities, whose religion differs from the majority, may use religious divergence to mobilize group members to perpetrate terrorism. Specifically we test the hypotheses that extremist factions of an excluded group will be more likely to carry out terrorist attacks when the group's members belong to a different religion as well as when they belong to a different denomination or sect of a religion than the majority. To test these propositions, we use data on ethnic minority party inclusion in government coalitions, ethnic minority group religion, and the Global Terrorism Database (GTD) by matching perpetrators with ethnic groups for all democracies, 1970-2004. © Taylor & Francis Group, LLC

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo
