Abstract We focus on the preservice teacher‐university supervisor relationship within the context of field experiences to explore the general question, “How can we, as university teacher educators, better assist preservice teachers in their development through field experiences?” Our discussion is based on: reflective accounts of preservice teachers written before, during, and following periods of field experience; our experiences as teachers and teacher educators, which include being faculty supervisors; and on research on the role of the university supervisor in field experiences. We first describe some typical perceptions associated with the preservice teacher‐university supervisor relationship, and then go on to suggest some specific ways to enhance the understanding that preservice teachers have of the roles of university supervisors and, hence, to facilitate the negotiation and development of productive preservice teacher‐university supervisor relationships. 相似文献

Abstract The purpose of this study was to investigate the functions of the gluteus minimus and gluteus medius muscles through the use of fine-wire electromyography. Electrical activity of the gluteus minimus and gluteus medius muscles of 13 subjects, six females and seven males, was recorded during a series of basic anatomical movements. Results showed that the gluteus minimus functioned as an abductor, medical rotator, extensor, and in some cases a flexor of the thigh. The gluteus medius functioned as an abductor, extensor, and medical rotator in six of the 13 subjects. It also exhibited some activity during flexion in five of the subjects tested. 相似文献

Olympic combat sports separate athletes into weight divisions, in an attempt to reduce size, strength, range and/or leverage disparities between competitors. Official weigh-ins are conducted anywhere from 3 and up to 24?h prior to competition ensuring athletes meet weight requirements (i.e. have ‘made weight’). Fighters commonly aim to compete in weight divisions lower than their day-to-day weight, achieved via chronic and acute manipulations of body mass (BM). Although these manipulations may impair health and absolute performance, their strategic use can improve competitive success. Key considerations are the acute manipulations around weigh-in, which differ in importance, magnitude and methods depending on the requirements of the individual combat sport and the weigh-in regulations. In particular, the time available for recovery following weigh-in/before competition will determine what degree of acute BM loss can be implemented and reversed. Increased exercise and restricted food and fluid intake are undertaken to decrease body water and gut contents reducing BM. When taken to the extreme, severe weight-making practices can be hazardous, and efforts have been made to reduce their prevalence. Indeed some have called for the abolition of these practices altogether. In lieu of adequate strategies to achieve this, and the pragmatic recognition of the likely continuation of these practices as long as regulations allow, this review summarises guidelines for athletes and coaches for manipulating BM and optimising post weigh-in recovery, to achieve better health and performance outcomes across the different Olympic combat sports. 相似文献

An extensive literature review and a phenomenological heuristic case study examined a virtual work team to determine what were salient domains of the team and determine the effect the virtual work environment had upon these domains. The study determined that post‐modern philosophy and postindustrial society are linked to changes in the marketplace and the development of virtual work environments. Seven team domains were identified. The virtual work environment affects the communication domain of teams most strongly. This effect impacts the remaining domains. Decision processes were determined to be narrower and featured conformity. Effectiveness was shown to be diminished by the reduction of social facilitation and increase in social loafing. Leadership was affected by the change in the communication network from an all‐channel network to a wheel network. Relationship and trust were affected by erosion of trust. Roles changed with the team's reduced ability to resolve differences and execute detailed action. Purpose became more task‐oriented. Technology emerged in the study as the new virtual team domain. Factors involved in team members' satisfaction were related to personality, isolation, and team membership. 相似文献

The virtual organization is one result of the rapid advances of technology. These advances, however, bring about setbacks when communicating electronically—primarily a loss of face‐to‐face interaction. Yet interpersonal skills are still deemed one of the most desirable communication skills in today's workplace. A gap analysis of the traditional versus the virtual office reveals that voids exist when communicating solely electronically. Electronic communication training is essential in order to eliminate these voids and lessen the chance for unclear messages, enhance “faceless” interactions, and avoid communication overload. Therefore, it is incumbent upon educators and trainers to augment development programs with electronic communication training in order for employees to be prepared for the challenges of the virtual office. 相似文献

This study describes verbal interactions in 13 selected training sessions across the United States using the INTERSECT instrument. More than two‐thirds of the interactions were found to be acceptance, the mere acknowledgment of a response by the instructor, with remediation accounting for about 21%, and praise, 11%. Criticism occurred only 4 times, or 18%. Male trainers provided more acceptance responses than female trainers at a statistically significant level. There were no differences in verbal classroom interactions based on gender equity during instruction. 相似文献
