After discussions between the Editors-in-Chief and the authors, it has been decided that this paper should be retracted due to errors in the results tables, specifically the regression coefficients and standard errors do not fit with the significance levels of some variables in a few models in the paper. The author notified the Editors-in-Chief of these errors on the 5th of June 2012.
