回想起来,"忍者追捕"涉及的是一个席卷斯塔顿岛的连环"忍者盗贼"。"武当乐队"正是发祥此地且名声在外,出于对功夫电影的敬意,在很久以前他们把这个地方戏称为"少林"。这个特别的盗贼,如今已被认定在过去的七个月里洗劫了十八户人家。九月,他在东安山的基奥洛家作案时,遇到了当地居民菲儿·基奥洛,"忍者盗贼"之恶名便是源自此案。他一身黑衣,戴着黑色面具,基奥洛说道,那盗贼还拿着双节棍。他用那副双节棍击打基奥洛的 相似文献

Abstract The purpose of this study was to compare one-repetition maximum (1-RM) and muscle activity in three chest-press exercises with different stability requirements (Smith machine, barbell, and dumbbells). Twelve healthy, resistance-trained males (age 22.7 ± 1.7 years, body mass 78.6 ± 7.6 kg, stature 1.80 ± 0.06 m) were tested for 1-RM of the three chest-press exercises in counterbalanced order with 3–5 days of rest between the exercises. One-repetition maximum and electromyographic activity of the pectoralis major, deltoid anterior, biceps, and triceps brachii were recorded in the exercises. The dumbbell load was 14% less than that for the Smith machine (P ≤ 0.001, effect size [ES] = 1.05) and 17% less than that for the barbell (P ≤ 0.001, ES = 1.11). The barbell load was ~3% higher than that for the Smith machine (P = 0.016, ES = 0.18). Electrical activity in the pectoralis major and anterior deltoid did not differ during the lifts. Electrical activity in the biceps brachii increased with stability requirements (i.e. Smith machine <barbell <dumbbells; P ≤ 0.005; ES = 0.57, 1.46, and 2.00, respectively), while triceps brachii activity was reduced using dumbbells versus barbell (P = 0.007, ES = 0.73) and dumbbells versus Smith machine (P = 0.003, ES = 0.62). In conclusion, high stability requirements in the chest press (dumbbells) result in similar (pectoralis major and anterior deltoid), lower (triceps brachii) or higher (biceps brachii) muscle activity. These findings have implications for athletic training and rehabilitation. 相似文献

The use of problem-solving in science instruction implies a change in the teacher's role from dispensing content information
to encouraging critical reflective thinking in the student. For problem-solving to become an integral part of the science
curriculum, teachers must make it the focus of their instruction. This study investigated the extent to which pre-service
primary teachers used the problem-solving approach in their science instruction. It also identified the factors affecting
their efforts to teach science using this approach. The issues considered are important in whether problem-solving becomes
part of the science curriculum, as teaching behaviour influences student learning outcomes.

Research into teacher inservice in primary science generally focuses on evaluating the objectives of each program in terms
of the immediate outcomes. Little research appears to have been conducted into the long term effects of interactive inservice
programs on the classroom practice of the participants. During 1993 the long term effects of participation in the Primary
Science/Technology Project (Sci-Tec), as perceived by the teacher participants, were investigated. Focus teachers who had
participated in Sci-Tec between 1988–1991 were asked to provide information about their current science teaching practice,
and about the influence that Sci-Tec had had on their current practice. Six of these teachers were then interviewed to determine
which specific aspects of the project they believed had most influenced the development of their current classroom practice
in teaching science.

Previous studies indicate that elastic resistance bands (ERB) can be a viable option to conventional resistance-training equipment (CRE) during single-joint resistance exercises, but their efficacy has not been established for several commonly used multiple-joint resistance exercises. Thus, we compared muscular activation levels in four popular multiple-joint exercises performed with ERB (TheraBand®) vs. CRE (Olympic barbell or cable pulley machines). In a cross-over design, men and women (n?=?29) performed squats, stiff-legged deadlifts, unilateral rows and lateral pulldown using both modalities. Multilevel mixed-effects linear regression analyses of main and interaction effects, and subsequent post hoc analyses were used to assess differences between the two resistance-training modalities. CRE induced higher levels of muscle activation in the prime movers during all exercises (p?<?.001 for all comparisons), compared to muscle activation levels induced by ERB. The magnitude of the differences was marginal in lateral pulldown and unilateral rows and for the erector spinae during stiff-legged deadlifts. In squats the quadriceps femoris activations were substantially lower for ERB. The differences between ERB and CRE were mostly observed during the parts of the contractions where the bands were relatively slack, whilst the differences were largely eliminated when the bands became elongated in the end ranges of the movements. We conclude that ERB can be a feasible training modality for lateral pulldowns, unilateral rows and to some extent stiff-legged deadlifts, but not for the squat exercise. 相似文献

The attitude towards science of first year early childhood education students was explored using an instrument developed for
the purpose. The instrument comprises four Likert-type scales, biographical items and two open-ended attitude items. The four
scales, characterised as ‘confidence’, ‘enjoyment’, ‘usefulness’ and ‘appropriateness of science for young children’, were
supported by varimax factor analysis and had reliabilities from 0.83 to 0.88. Use of the combined scales as a general ‘attitude
towards science’ scale was supported by principal components analysis; reliability for the combined scale was 0.94. Comments
made in response to the open-ended items supported the validity of the scales. For the student group as a whole, mean scores
on all scales were slightly to moderately positive, with the highest mean being for the ‘science for young children’ scale.
Students who had studied at least one science subject at Year 12 level had significantly higher scores on all scales than
students who had not studied science at senior level.

Instructional technology, especially the use of computers and the Internet has been lagging behind in the German educational system in comparison to other European countries. When this lack was realized in the second half of the 1990s it had quite a “shock-effect” but one of the healthy kind: Since then numerous public and private initiatives have been started to advance the use of technology in schools, higher education, and in vocational training. At the college and university level, there is a trend towards connecting online and offline courses. Also, it was understood that it is not enough to just provide schools and universities with the technology needed but that the introduction of technology has to be accompanied by profound systemic and structural changes. Thus, there is great hope that the use of technology in education will fuel educational innovations at all levels needed for educating and training pupils and students to act as responsible and media-literate citizens in a modern world. 相似文献
