Substitutes for leadership in anaesthesia teams and their impact on leadership effectiveness

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care.     

Positivity bias in employees' self-ratings of performance relative to supervisor ratings: The roles of performance type,performance-approach goal orientation,and perceived influence

As hypothesized, data from two field studies among employees and their supervisors showed that employees are more likely to positively bias their self-ratings relative to supervisor ratings when creative performance rather than inrole performance is being evaluated. In addition, employees' performance-approach goal orientation and perceived influence were found to enhance positivity bias in self-ratings of creative performance. Moreover, performance-approach goal orientation and perceived influence appeared to combine and interact in their effects, such that the impact of perceived influence on positivity bias in self-ratings was larger when performance-approach goal orientation was weaker rather than stronger.     

When and why creativity‐related conflict with coworkers can hamper creative employees' individual job performance

We examined when and why focal employees' creativity-related conflict with coworkers is related to their individual job performance. As hypothesized, a survey among 113 employees in 14 manufacturing work groups showed that creativity-related conflict with coworkers escalates into dysfunctional relationship conflict when focal employees have low rather than high trust in those coworkers. In its turn, relationship conflict with coworkers was found to be negatively associated with focal employees' individual job performance when they lack support from their supervisor. Finally, the indirect effect of creativity-related conflict on job performance through relationship conflict was found to be significant when both the first stage moderator of coworker trust and the second stage moderator of supervisory support were low rather than high.     

Temporal coordination between performing musicians

Many common behaviours require people to coordinate the timing of their actions with the timing of others' actions. We examined whether representations of musicians' actions are activated in coperformers with whom they must coordinate their actions in time and whether coperformers simulate each other's actions using their own motor systems during temporal coordination. Pianists performed right-hand melodies along with simple or complex left-hand accompaniments produced by themselves or by another pianist. Individual performers' preferred performance rates were measured in solo performance of the right-hand melody. The complexity of the left-hand accompaniment influenced the temporal grouping structure of the right-hand melody in the same way when it was performed by the self or by the duet partner, providing some support for the action corepresentation hypothesis. In contrast, accompaniment complexity had little influence on temporal coordination measures (asynchronies and cross-correlations between parts). Temporal coordination measures were influenced by a priori similarities between partners' preferred rates; partners who had similar preferred rates in solo performance were better synchronized and showed mutual adaptation to each other's timing during duet performances. These findings extend previous findings of action corepresentation and action simulation to a task that requires precise temporal coordination of independent yet simultaneous actions.     

Ageing and attentional control

The research examines the structural bottleneck account and the resource account of the substantial dual-task deficits among older adults. Procedures from two common dual-task methodologies—the psychological refractory period and the relative-priority manipulation—were used to encourage maximization of the joint performance. Performance and time-sharing strategies from subjects between the ages of 20 and 70 years were examined. Age-related declines in time-sharing efficiency and in the precision of the executive control process were observed. The age-related effect was larger when two manual responses were required than when one manual and one vocal response were required, but no evidence for obligatory sequential processing was found. Except for the most demanding conditions, comparable practice effects were observed between the younger and older subjects, suggesting considerable cognitive plasticity in the older subjects. Implications for the two attentional accounts were discussed.     

Fairness And Performance-Enhancing Swimsuits AT The 2009 Swimming World Championships: The ‘Asterisk’ Championships

The use of polyurethane swimsuits at the 2009 World Aquatics Championships resulted in world records being set for almost all swimming events. This paper explores the implications that the use of these performance-enhancing swimsuits had on fairness in relative and absolute outcomes in swimming. I claim that the use of ‘super swimsuits’ unfairly influenced relative outcomes within the competition because not all swimmers used, or had access to, the same types of swimsuit (some of which were clearly ‘faster’ than others). Furthermore, I claim that the use of performance-enhancing swimsuits by current competitors unfairly influences inter-temporal relative outcomes. It is evident that competitors and coaches in elite swimming place great importance on making inter-temporal comparisons on the basis of absolute outcomes in the sport (as measured by a swimmer's race time). A ban on the use of super swimsuits may be justified in order to preserve the fairness of such inter-temporal comparisons, and records set using performance-enhancing swimsuits at the 2009 World Championships should be demarcated from others.     

From goal motivation to goal progress: the mediating role of coping in the Self-Concordance Model

Abstract

The present studies examined the mediating role of self-regulatory mechanisms in the relationship between goal motivation and goal progress in the Self-Concordance Model. First, a systematic review, using meta-analytical path analysis, supported the mediating role of effort and action planning in the positive association between autonomous goal motivation and goal progress. Second, results from two additional empirical studies, using structural equation modeling, lent credence to the mediating role of coping in the relationship between goal motivation and goal progress of university students. Autonomous goal motivation was positively associated with task-oriented coping, which predicted greater goal progress during midterm exams (Study 1, N=702) and at the end of the semester in a different sample (Study 2, N=167). Controlled goal motivation was associated with greater disengagement-oriented coping (Study 1 and Study 2) and lesser use of task-oriented coping (Study 2), which reduced goal progress. These results held up after controlling for perceived stress (Study 2). Our findings highlight the importance of coping in the “inception-to-attainment” goal process because autonomous goal motivation indirectly rather than directly predicts goal progress of university students through their usage of task-oriented coping.     

The association between maternal strategies and preschoolers' memory for location of objects

Using a Vygotskian theoretical framework and a social interaction design, we observed 30 middle-class North American mother–child dyads engaged in a location memory activity. The central aim of this investigation was to assess maternal and preschool strategy use employed during a memory for location task, and to determine which strategies are associated with preschooler accuracy of memory for location of objects. Results suggest that mothers are more apt to utilize labelling, encouragement, and guidance as opposed to location-specific assistance to their child during the task, and children are more apt to link the memory information to their real-life experiences, request help for assistance, and utilize self-regulatory speech. Implications of the research, suggestions for future research, and expansions of theoretical perspectives on the role of social interaction on preschool location memory performance, and educational implications are discussed.
