The current training model being used in higher education advocates the acquisition of competences aimed at providing students with all-round training that will enable them to tackle their future work responsibilities effectively. This encompasses a number of different competences, most notably the transversal kind, especially in view of the important role they play in shaping the profile of any professional individual. The active learning methods applied to group work have shown to be the most suitable for achieving these competences. From this perspective, and considering their relevance, we present the results of a study that addresses the perceptions held by students from Education Degrees regarding the extent to which transversal competences are acquired by implementing active learning methods. The students perceive group work as a dynamic that teaches them how to be more self-critical and committed to group-oriented tasks, thus encouraging communication skills, personal relationships and motivation. However, a lesser degree of acquisition has been recorded in other equally important competences. As such, it is necessary to promote these learning methods from the start, carefully designing and planning the curriculum structure as well as the tasks to be performed in order to avoid any negative implications that may arise. 相似文献

In order to assess lower extremity muscle mechanical properties in athletes, power-load characteristics during multi-joint tasks are frequently examined. This work compared 6 weeks of traditional (TP) and daily-undulated (DUP) periodized loaded countermovement jumping (CMJ). 20 amateur athletes (age: 24.2 ± 2.6 years, height: 175.6 ± 7.1 cm, body mass: 71.5 ± 7.7 kg, 10 males/10 females) exercised three times weekly using maximal CMJs with loads corresponding to 0%, 15% and 30% of body mass. Prior to the training period, subjects were once-only assigned by random to either the TP or DUP training scheme. Pre-to-post training, maximal center of mass (COM) -height, -take-off velocity, -power output and -impulse were compared during CMJ with additional loads corresponding to 0–30% of body mass. ANOVA (time * group) with repeated measures revealed significant (P < 0.05) temporal gains of maximal COM-height (2–11%), -take-off velocity (1–7%), -power (2–8%) and -impulse (3–9%) over most loading conditions for TP and DUP. However, ANOVA indicated no group effects for any outcome. Independent from the periodization model, maximal power output remained statistically unchanged with increased testing loads. For short-term conditioning periods, TP and DUP were equally effective in enhancing biomechanical jumping variables under varying loading conditions. 相似文献

Separation by dielectrophoresis of dormant and nondormant bacterial cells of Mycobacterium smegmatis
The dielectrophoretic behavior of active, dead, and dormant Mycobacterium smegmatis bacterial cells was studied. It was found that the 72-h-old dormant cells had a much higher effective particle conductivity (812±10 μS cm−1), almost double that of active cells (560±20 μS cm−1), while that of dead (autoclaved) M. smegmatis cells was the highest (950±15 μS cm−1) overall. It was also found that at 80 kHz, 900 μS cm−1 dead cells were attracted at the edges of interdigitated castellated electrodes by positive dielectrophoresis, but dormant cells were not. Similarly, at 120 kHz, 2 μS cm−1 active cells were attracted and dormant cells were not. Using these findings a dielectrophoresis-based microfluidic separation system was developed in which dead and active cells were collected from a given cell suspension, while dormant cells were eluted. 相似文献
