Teachers at eight elementary schools in a large metropolitan school district participated in a multi-year program of professional ethical dilemma discussions that took place at monthly school meetings over a two-year or three-year period and focused on real-life situations faced by elementary school teachers. Discussions were structured using the Four Component Model of Moral Judgment. The DIT-2 served as a measure of moral judgment. Results proved to be counterintuitive; teacher moral judgment did not improve over time. We discuss the implications of promoting moral and democratic sensibilities at a time when American classrooms are tightly controlled and teachers held accountable for student performance on high stakes tests. 相似文献

The aim of this study was to determine whether there is an effect of time of day on the adaptation to strength training at maximal effort. Fourteen participants took part in this experiment. Their peak anaerobic power (Wingate anaerobic test) and peak knee extension torque at six angular velocities (1.05, 2.10, 3.14, 4.19, 5.24 and 6.29 rad · s -1 ) were recorded in the morning (between 07:00 and 08:00 h) and in the evening (between 17:00 and 18:00 h) just before and 2 weeks after a 6 week course of regular training. Seven of them trained only in the morning and seven only in the evening. Multivariate analysis of variance revealed a significant group 2 pre-/post-training 2 time of day interaction effect for peak torque and peak anaerobic power. Before training, in both groups, peak torque and peak anaerobic power were significantly higher in the evening than in the morning. After training, there was no significant difference in peak torque and peak anaerobic power between the morning and the evening for the morning training group. In contrast, in the evening training group, peak torque and peak anaerobic power were higher in the evening than in the morning. As a result of training, both peak torque and peak anaerobic power increased from their initial values as expected. The morning training group improved their peak anaerobic power significantly in the morning and in the evening, the absolute increase being larger in the morning than in the evening. The evening training group did not improve their peak anaerobic power in the morning, whereas it improved significantly in the evening. Although peak torque was significantly improved by training in the morning and evening in both groups, the absolute increase was greater in the morning than in the evening in the morning training group, whereas the opposite was the case for the evening training group. These results suggest that training twice a week at a specific hour increases the peak torque and the peak anaerobic power specifically at this hour and demonstrates that there is a temporal specificity to strength training. 相似文献

Their peak anaerobic power (Wingate anaerobic test) and peak knee extension torque at six angular velocities (1.05, 2.10, 3.14, 4.19, 5.24 and 6.29 rad x s(-1)) were recorded in the morning (between 07:00 and 08:00 h) and in the evening (between 17:00 and 18:00 h) just before and 2 weeks after a 6 week course of regular training. Seven of them trained only in the morning and seven only in the evening. Multivariate analysis of variance revealed a significant group x pre-/post-training x time of day interaction effect for peak torque and peak anaerobic power.

This study analyzed the activity of expert table tennis players during a match, in reference to course of action theory (Theureau, 1992). Matches were videotaped, and the players' verbalizations as they viewed the tapes were collected a posteriori. The data was analyzed by (a) transcribing the players' actions and verbalizations, (b) decomposing their activity into elementary units of meaning, and (c) grouping the elementary units into larger sets. The results showed that the matches began with an inquiry into the specific features of the opponent's play. This was followed by reproducing the actions identified as effective during the inquiry. The results are discussed in relation to the role of training in expert performance. 相似文献

A review of the archival literature, including records and information management, indicates that archivists’ have shown over
the last two decades an interest in program evaluation. The sparceness of the literature on the subject suggests a gap in
an articulate body of knowledge, based on solid theoretical and methodological foundations, for evaluation of archival programs
and activities. However, if they have not particularly investigated the subject from a theoretical perspective, archivists
have developed in their different organizations and working environment practical knowledge of and experience with program
evaluation. In large corporations as well as in public bureaucracies, they have been part of or subjected to specific or generic
program evaluation initiatives conducted by internal and external evaluators. But archivists might need now to go some steps
further and to look from a critical perspective at what is needed in order to get full benefit from program evaluation. 相似文献

A method aimed at the development of an America’s Cup racing yacht bulb is developed and validated against experimental data.
The method relies heavily on Reynolds Averaged Navier Stokes computational fluid dynamics (CFD) and also factors in gravitational
and aerodynamics effects through the use of a Velocity Prediction Program. Initial extensive use of towing tank results is
made to be able to validate the CFD solution and thus develop a solid ground for predictive work. Then, in order to narrow
down the focus on bulb developments, decoupled hypotheses are made on the influence of the hull and free surface wave. The
development of a detailed performance analysis chart of a known base bulb allows the use of a relatively small series of CFD
simulations together with physical hypotheses to assess any given bulb performance relative to the known base. The discussion
of the results on a specific development highlights the promises and limitations of the method; final full scale results are
discussed and analysed as well. 相似文献

In this study, we examined the effects of three recovery intensities on time spent at a high percentage of maximal oxygen uptake (t90[Vdot]O(2max)) during a short intermittent session. Eight endurance-trained male adolescents (16 +/- 1 years) performed four field tests until exhaustion: a graded test to determine maximal oxygen uptake ([Vdot]O(2max); 57.4 +/- 6.1 ml x min(-1) . kg(-1)) and maximal aerobic velocity (17.9 +/- 0.4 km x h(-1)), and three intermittent exercises consisting of repeat 30-s runs at 105% of maximal aerobic velocity alternating with 30 s active recovery at 50% (IE(50)), 67% (IE(67)), and 84% (IE(84)) of maximal aerobic velocity. In absolute values, mean t90[Vdot]O(2max) was not significantly different between IE(50) and IE(67), but both values were significantly longer compared with IE(84). When expressed in relative values (as a percentage of time to exhaustion), mean t90[Vdot]O(2max) was significantly higher during IE(67) than during IE(50). Our results show that both 50% and 67% of maximal aerobic velocity of active recovery induced extensive solicitation of the cardiorespiratory system. Our results suggest that the choice of recovery intensity depends on the exercise objective. 相似文献
