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
Preparing Successful Science Teachers at Indiana University Southwest

Competencies through the eyes of the psychologist: A closer look at assessing competencies
Competencies have become a leading construct in human resource practices. However, empirical research on competencies has lagged behind resulting in a gap between practice and science. In this study, the focus was on the nature of competencies by examining the relationships of three competency dimensions with cognitive ability, personality and performance during assessment center exercises. Data of 932 applicants participating in a 1-day selection procedure were used. Results showed that to assess the competency dimension Thinking psychologists focus on cognitive ability. To assess the competency dimension Feeling psychologists rely on performance during interview simulation exercises and on measures of personality. In assessing the dimension Power psychologists focus mainly on personality, although they also rely on cognitive ability and performance during interview simulation exercises.
