With the increase in academic specialty,scholars and leaders have sought new ways tostrengthen intellectual community. Their strategiesinclude experimenting with organisational structuresto bring about desired change. This qualitative casestudy examines the influences of such a structure. The Luce Seminars was a programme designed to supportsustained faculty conversation across disciplines atEmory University, a research university located in theUnited States. The analysis found that key functional and symbolic aspects of the program contributed to intenseparticipant involvement, resulting in broadened anddeepened intellectual discourse, enhanced disciplinaryorientation, and expanded possibilities for teachingand research. The authors conclude that structuredfaculty conversation across disciplines strengtheneddimensions of faculty culture related to interactionand scholarship at the university and suggest somebroad areas for future research. 相似文献

Bereavement is a state of grieving after the loss of a loved one. Past research has suggested that bereavement is particularly challenging, both physically and emotionally, in the aftermath of unexpected death. Here, we examine bereavement in which death occurred suddenly, compared to a chronic condition where death was expected, in terms of perceived social support and relational maintenance with the deceased in the form of imagined interactions and social media interactions. Results indicated that individuals experiencing sudden death bereavement were more likely to engage in both postmortem relational maintenance techniques and perceived less social support than individuals in the expected death bereavement group. Results are discussed in terms of previous findings. 相似文献

The aim of this study was to quantify joint compression and shear forces at L4/L5 during exercises used to overload the hips. Nine men performed 36 "walking" trials using two modalities: (1) sled towing and (2) exercise bands placed around the ankles. Participants completed forward, backward, and lateral trials with bent and straight legs at three separate loads. Surface electromyography (EMG) was recorded bilaterally from eight torso and thigh sites, upper body and lumbar spine motion were quantified, and hand forces were measured. An EMG-driven musculoskeletal model was used to estimate the muscular contribution to joint compression and shear. Peak reaction, muscle and joint compression and shear forces, and peak gluteus medius and maximus activity were calculated. Significant differences were noted in each dependent measure; however, they were dependent on direction of travel, leg position, and load. The highest joint compression and shear forces for the sled and band conditions were 4378 N and 626 N, and 3306 N and 713 N, respectively. In general, increasing the band tension had little effect on all dependent measures, although a load-response was found during the sled conditions. Before using any exercise to improve hip function, the potential benefits should be weighed against "costs" to neighbouring joints. 相似文献

The focus of this narrative inquiry was to examine how teachers describe influences on their instructional decisions in mathematics. Using a lens provided by pivotal or prototypical stories teachers told about their past experiences, connections were suggested between these past experiences and their instructional decisions. These connections helped to illustrate how instructional decisions may be shaped by priorities and beliefs established earlier in life, as well as by current contexts. Further research on the use and characteristics of prototypical stories is suggested. 相似文献

Explosive upper-body movements, with which the load is not thrown (non-ballistic), may comprise a phase during which forces are produced in opposition to the motion of the load. Thirty men completed three test sessions (free weight, ballistic, and pneumatic), each consisting of a one-repetition maximum (1-RM) and four explosive repetitions of a bench press at six loads (15, 30, 45, 60, 75, and 90% 1-RM). The end of the lifting phase for the non-ballistic conditions (free weight and pneumatic) was defined by: the point of peak barbell displacement and the point at which the vertical force became negative (positive work). When analysed by peak displacement, the ballistic condition elicited significantly greater mean velocity, force, and power at loads of 15–60% 1-RM compared with the free weight condition. When the period of negative work was removed, the mean free weight velocity, force, and power at loads below 60% 1-RM increased. Consequently, the only differences between the free weight and ballistic conditions were found at loads of 15% and 30% 1-RM. Including a period of negative work may underestimate all kinematic and kinetic variables dependent on the time to, or position of, the end of the lifting phase, for non-ballistic efforts. 相似文献
