The aim of this case study was to determine whether a sailor's deliberate choice of a conservative strategy to manage sleep deprivation would allow him to cross the Pacific Ocean and to minimize his state of anxiety and perceived fatigue. The participant, who had more than 10 years' sailing experience in severe conditions, was tested on a small catamaran without any living quarters during a solo Pacific Ocean crossing. Estimations of sleep hours, state anxiety, and perceived fatigue were self-reported by the sailor on a daily basis using a specific questionnaire. The most important finding is that the sailor's deliberate sleep strategy, 5.4 h sleep per day (24% less than on-shore), was enough to keep his anxiety and perceived fatigue within acceptable limits and enabled him to achieve his goal, which was the first crossing of the Pacific Ocean on a catamaran of less than 6 m. In conclusion, our results suggest that the sailor observed in the present case study was able to minimize anxiety and perceived fatigue with adequate sleep to optimize his performance, security, and to achieve his goal.  相似文献

The primary objectives of this investigation were to examine the attributions, emotional reactions, and coping strategies of shy/withdrawn and aggressive girls and boys and to examine whether such social cognitions differ within the relationship context of friendship. Drawn from a sample of fifth and sixth graders (M age = 10.79 years; SD = .77), 78 shy/withdrawn, 76 aggressive, and 85 control children were presented with hypothetical social situations that first involved unfamiliar peers, and then a mutual good friend. Results revealed group and gender differences and similarities, depending on the relationship context. From our findings emerges a central message: friends' involvement during interpersonal challenges or stressors mitigates children's attributions, emotions, and coping responses.  相似文献

This article argues that Philip Pullman’s His Dark Materials may be read as a series which attempts to assault the Christian doctrine of God. We believe that this demonstrably accords with Pullman’s personal views, and that, through his story, he seeks to foster such views in his readership. However, the accuracy of his attack falls short of its intended mark when it is examined alongside classical Christian theology. The Authority which Pullman’s narrative destroys is actually more akin to the Christian view of the devil than he is the divine, and the victories of Will and Lyra—as a new Adam and Eve—have strong resemblances to the victories which Christianity claims for Christ and Mary. Pullman’s narrative, therefore, becomes an inversion of his deicidal intention rather than an inverting and revolutionary destruction of theology.

The importance of strategic planning in education has been increasingly recognised but observations of school principals have shown that little time is apparently devoted to reflective planning. This case study of a secondary college principal, aimed to discover if the reflective practitioner exists by extending non‐participant observation to include the content and timing of a principal's thinking periods. The evidence from observation was also used to find out if planned strategies were translated into actions.  相似文献

Community college presidents face an uphill struggle in preparing their institutions for the rapidly changing technological learning environment. Visionary presidents in rural community colleges are presented with yet another challenge: that of finding themselves on the wrong side of the digital divide. This article describes how presidents of 12 rural community colleges in the mountains of western North Carolina formed a technology consortium to collaboratively address critical technology issues. Integral steps in the joint venture were a combined assessment and planning process authorized by the presidents, formation of the Western North Carolina Technology Consortium, and an e-commerce project designed to meet the needs of small busi-nesses and entrepreneurs in the region. Lessons learned and implications for practice are presented for community college presidents seeking ways to collaborate.  相似文献
