December 1989 meant for the Romanian academie world the break off with the communist dogmaticism and the politics of indoctrination and also the possibility of installing a critical analysis and the continuity of the true values of Romanian universities. Two inquiries conducted in 1990 and 1991 among students and Professors revealed a strong contesting pathos (persons, teaching contents and methods. The entire educational System were contested) and also a true desire to find out the critical aspects which enhances a new ideology in the higher education System. Students and a part of the faculty have discovered expressions like “academic freedom” and “academie autonomy”. They started to use concepts like “change”, “academic democracy”, “social responsibility”. New expectations concerning the behavioural offer of Professors occurred. When defining the direction of this change, authors chose the expression “toward normality”. Indices of normality could be the assumption by the university of new functions and value orientations previously forgotten and abandoned, under the dictatorial system such as creation and diffusion of values, introduction of criteria of competence and morality in evaluating both academic status and behaviour of Professors. 相似文献

The effects of changing pace on metabolism and stroke characteristics during high-speed breaststroke swimming 总被引:1,自引:0,他引:1
Performances often vary between the heats and finals of breaststroke swimming competitions possibly because the swimmers try to conserve their energy, or for other tactical reasons. Additionally, coaches might advise either a 'positive' or 'even' pace race strategy during the final. The effect of such pacing changes on metabolism (blood lactate, heart rate, ventilation), ratings of perceived exertion, stroke kinematics and turning times have not been investigated. Nine male competitive breaststroke swimmers swam three paced (Aquapacer) 200-m trials, 48 h apart and in random order, at 98%, 100% and at an attempted 102% of their maximal 200-m time-trial speed. Responses in metabolic variables were similar between the 98% and 100% trials, but higher post-exercise blood lactate concentrations and respiratory exchange ratios were observed following the 102% trial. As the pace of trials increased, stroke rate was found to increase proportionately with stroke count. However, during the latter stages of the 100% trial, a disproportionate increase in the stroke count was observed, which led to a significant pacing error. This feature was more obvious in the 102% trial, where participants demonstrated 'positive pacing' and reported higher ratings of perceived exertion than for the 98% trial. During the early stages of the trials, turning times were initially shorter the faster the pace of the trial; however, as the trials progressed, this pattern was found to reverse. We conclude that a slight reduction in pace during near maximal breaststroke swimming altered kinematic but not post-exercise metabolic responses, while an increase in pace led to positive pacing and an increase in both kinematic responses and anaerobic metabolism. 相似文献

We designed and constructed a sundial for the purpose of observing the declination of the sun and thus marking solar seasonal variation. The 122 × 122 cm vertical sundial on the south-facing wall of our library has two unusual features: a nodus on the gnomon that casts a shadow of a point for marking the height of the sun and a large blank working space for students to mark the shadow of the nodus at different hours of the day and to connect the marks of 1 day in a line of declination. We discuss the design of a dial that emphasizes a working space for observations on solar declination, methods for determining the position of the nodus such that lines of declination can be observed every day of the year, mathematical procedures that minimize error in laying out the hour lines for this unusual design, the type of materials that are best suited for this design, and how students in an interdisciplinary honors colloquium on seasonal rhythms used the sundial. We also include two appendices on general sundial construction that indicates the information designers need to construct their own sundials. 相似文献
