Process gain and process loss: comparing interpersonal processes and performance of culturally diverse and non-diverse teams across time

Members of 82 student groups involved in a Team Learning instructional format were surveyed with the Group Style Instrument (GSI) to examine the possible dimensions of team oriented behaviors and individualistically oriented behaviors. Exploratory factor models and confirmatory factor models were compared to find the best factor structure fit. The GSI was found to have dimensions that were team and individualistically oriented. From a second sample data was collected across four months on the group process and group performance of culturally non-diverse and culturally diverse groups. Data were evaluated in two significant ways. First, the team orientation and individual orientation dimensions were used to define interpersonal processing. Second, the team process dimensions were used to define interpersonal processing. Second, the team process dimensions were examined further to evaluate their relation to group performance. Early on the diverse teams showed less team orientation and more individual orientation than non-diverse teams, but through frequent feedback on task and interpersonal processing, the diverse teams caught up by the third time period. By the end, diverse teams maintained high team orientation but also allowed a reasonable extent of individual orientation. The diverse teams were beginning to utilize diversity to their advantage. Team and Individualistic orientations showed significant relations to team performance across time. Suggestions are given for future research.  相似文献   

Kinetic changes during a six-week minimal footwear and gait-retraining intervention in runners

An evaluation of a six-week Combined minimal footwear transition and gait-retraining combination vs. gait retraining only on impact characteristics and leg stiffness. Twenty-four trained male runners were randomly assigned to either (1) Minimalist footwear transition Combined with gait-retraining over a six-week period (“Combined” group; n = 12) examined in both footwear, or (2) a gait-retraining group only with no minimalist footwear exposure (“Control”; n = 12). Participants were assessed for loading rate, impact peak, vertical, knee and ankle stiffness, and foot-strike using 3D and kinetic analysis. Loading rate was significantly higher in the Combined group in minimal shoes in pre-tests compared to a Control (P ≤ 0.001), reduced significantly in the Combined group over time (P ≤ 0.001), and was not different to the Control group in post-tests (P = 0.16). The impact peak (P = 0.056) and ankle stiffness reduced in both groups (P = 0.006). Loading rate and vertical stiffness was higher in minimalist footwear than conventional running shoes both pre (P ≤ 0.001) and post (P = 0.046) the intervention. There has a higher tendency to non-rearfoot strike in both interventions, but more acute changes in the minimalist footwear. A Combined intervention can potentially reduce impact variables. However, higher loading rate initially in minimalist footwear may increase the risk of injury in this condition.  相似文献   

The physical demands of elite English rugby union   总被引：1，自引：1，他引：0

The aim of this study was to assess the physical demands of elite English rugby union match-play. Player movements were captured by five distributed video cameras and then reconstructed on a two-dimensional plane representing the pitch. Movements based on speeds were categorized as standing, walking, jogging, and medium-intensity running (low-intensity activity), and high-intensity running, sprinting, and static exertion (scrummaging, rucking, mauling, and tackling) (high-intensity activity). Position groups were defined as forwards (tight and loose) and backs (inside and outside). Backs travelled more total distance than forwards (6127 m, s=724 vs. 5581 m, s=692; P<0.05) and greater distances in walking (2351 m, s=287 vs. 1928 m, s=2342; P<0.001) and high-intensity running (448 m, s=149 vs. 298 m, s=107; P<0.05). Forwards performed more high-intensity activity than backs (9:09 min:s, s=1:39 vs. 3:04 min:s, s=1:01; P<0.001), which was attributable to more time spent in static exertion (7:56 min:s, s=1:56 vs. 1:18 min:s, s=0:30; P<0.001), although backs spent more time in high-intensity running (0:52 min:s, s=0:19 vs. 1:19 min:s, s=0:26; P=0.004). Players travelled a greater distance in the first 10 min compared with 50-60 and 70-80 min, but there was no difference in the amount of high-intensity activity performed during consecutive 10-min periods during match-play. These results show the differing physical demands between forwards and backs with no evident deterioration in high-intensity activity performed during match-play.  相似文献
