The mediating role of mood in the relationship between perseverative cognition,sleep and subjective health complaints in music students

Objective: Subjective health complaints (SHC) are frequent in musicians. These complaints may be particularly distressing in this population because they are performance relevant. This paper aims at testing a model positing that (a) perseverative cognition (PC) predicts sleep duration/quality, (b) sleep duration/quality predicts SHC and (c) mood is a mediator of these associations.

Design: Participants were 72 music students (mean age (SD): 22.7 (3.0) years), and the assessment period consisted of seven consecutive days, with a solo performance on the fifth day.

Main outcome measures: Self-reported total sleep time (TST) and sleep quality were assessed 30?min after wake-up, and objective TST/sleep quality were assessed with an actigraphy watch. PC and mood were measured five times a day. Daily SHC were assessed at 9 p.m.

Results: PC did not significantly predict sleep duration/quality. Self-reported and objective TST and sleep quality were all significantly associated with SHC. Mood played a mediating role in each of these relationships with the exception of objective sleep quality.

Conclusion: The tested model on the association among PC, sleep and SHC and the mediating role of mood received partial support, highlighting the importance of sleep and mood in the emergence of SHC among university music students.     

Optimism and Positivity Biases in Performance Appraisal Ratings: Empirical Evidence from Professional Soccer

Using unique assessment data for players from a German Bundesliga club’s youth academy, we tested four core hypotheses on how player ratings and rater or ratee-related characteristics reflect the (prospective) optimism bias and (retrospective) positivity bias. The results indicate not only that the ratings of predicted and remembered performance are indeed higher than the talents’ actual performance throughout a season, but that these differences depend positively on the rater’s organizational experience and negatively on the amount of ratee data available. They also suggest that (prospective) anticipation is even more positively biased than (retrospective) recollection of player performances, underscoring the asymmetry between looking forward and looking backward.     

Diffusion of an effective skin cancer prevention program: design, theoretical foundations, and first-year implementation.

This article describes the design and theoretical foundations of the Pool Cool Diffusion Trial and reports 1st-year findings. Aims of the study are to evaluate the effects of 2 strategies for diffusion of the Pool Cool sun safety program on implementation, maintenance, and sustainability; improvements in environmental supports for sun safety in swimming pools; and sun protection habits and sunburn among participating children. There was a high rate of program participation (86.6%; n=375 swimming pools) in the 1st year and somewhat lower study participation (75.8%). Analysis of pool manager surveys revealed a time effect for overall sun safety programs and for sun safety policies, environmental strategies, and programs for pool users. There were few differences in implementation between treatment groups in year one.

Social Identity and Corporate Mergers

Corporate mergers require proper human resources management to reach their financial and strategic objectives and minimize negative consequences for employee well‐being. Understanding the antecedents of employees’ identification with the merged organization during the corporate merger is crucial, because stronger post‐merger identification results in less conflict and higher levels of motivation. Unfortunately, employees often identify more strongly with their pre‐merger organizations than with the merged organization. One influential approach to understanding the processes underlying organizational identification is the social identity approach ( Tajfel & Turner, 1986 ; Turner, Hogg, Oakes, Reicher, & Wetherell, 1987 ). Research applying this perspective to organizational mergers shows that levels of identification with the merged organization are partly explained by status and dominance differences of the involved organizations, by motivational threats and uncertainties during the merger, and by the representation of the post‐merger identity. Leaders and managers of corporate mergers are able to influence these processes and, thus, to provide a path for successful merger integration.
