Understanding work-related social media use: An extension of theory of planned behavior.

This study examines the motives of employees to engage in work related social media use - i.e. the use of personal social media accounts to communicate about work-related issues. The theory of planned behavior (TPB) was used to explain this behavior. Because social media can enable users to express their identities, social identity expressiveness and self-identity expressiveness were added to the TPB model. Through an online questionnaire, using purposive sampling technique, 514 Dutch employees were asked about their social media use and motivation to do so. We used structural equation modelling (SEM) to test our hypotheses. Results indicate that these identity constructs enhance the predictive ability of the TPB. As such, workrelation social media use is likely to take place spontaneously rather than deliberately and consciously planned

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

Headwinds in sports sponsoring

Purpose The purpose of this paper is to investigate the effects of a crisis situation in a sports team on the credibility of their sponsor and how the sponsor’s use of various crises response strategies may repair the damage done to their credibility. Design/methodology/approach A scenario experiment was conducted with a 2 (pre-/post-crisis) × 4 (sponsor response strategy: denial/distancing/rebuild/no response) mixed factor design. Respondents (n=191) were recruited from a research panel. Findings The results confirmed the existence of a spill-over effect: the sponsor’s credibility dropped as a result of the crisis. More interestingly, the effects of the crisis on sponsor credibility were moderated by the response strategy of the sponsor: the harm that the crisis did to the sponsor credibility was aggravated by a denial strategy, but somewhat weakened by a diminishing strategy. A rebuild response unexpectedly improved the credibility of the sponsor. Practical implications While partnerships in sports can be risky, because crises can be contagious, such partners can also help one another to protect their credibility. Therefore, this study advocates an integral approach of crisis communication. Sponsors may improve their credibility when they frame their contribution to the solution to the problems as an authentic effort to do good. Originality/value Starting from an issue arena perspective, this contribution shows how crises in sports teams also affect sponsors and how sponsors can contribute to the restoration of the damaged credibility with suitable responses to the crisis situation
