Students' understanding of biological phenomena are analysed via the ontological categories of processes and matter. The analysis is based on tenth graders' explanations regarding biological phenomena such as photosynthesis, energy resources, temperature regulation and interrelations between living/nonliving worlds. This direction of analysis is an attempt to flow with the more meaningful trend of biological research and thought, that emphasizes the importance and fruitfulness of the process approach. Some implications regarding biology learning and teaching are suggested. 相似文献

我国优秀乒乓球人才流动特征分析 总被引:1,自引:0,他引:1
通过对新中国成立以来不同时期中国优秀乒乓球人才国内、国外流动方向、范围、规模等方面的研究,探究我国优秀乒乓球人才流动的特征与趋势,结果表明:(1)优秀乒乓球人才流动始终以垂直流动为主要方式;(2)优秀乒乓球人才在国内、国际流动的区域呈现出不均衡的分布趋势;(3)优秀乒乓球人才资源丰富与基层群众文化发展的急需相矛盾、脱节;(4)优秀乒乓球人才职业转换的跨度、范围增大,自主性流动趋势增强;(5)优秀乒乓球人才的流动促进r乒乓球运动全球化整体的发展与提高,推动了中国文化的繁荣与世界文化的全面交融. 相似文献

通过对原陕西省乒乓球队和各种类型的乒乓球俱乐部的调查,探讨了陕西省各地区乒乓球运动产业开展的现状和出现的新情况。结果发现:双轨制下的陕西省乒乓球运动产业发展是由现阶段陕西省的基本情况决定的;陕西省乒乓球运动产业链主体“金字塔”模式基本形成;现阶段陕西省发展乒乓球俱乐部是可行的,但是乒乓球产业化环境并不完善。 相似文献

This paper provides a new and systematic characterization of 488 universities, from 11 European countries: Finland, France, Germany, Hungary, Italy, Netherlands, Norway, Portugal, Spain, Switzerland and UK. Using micro indicators built on the integrated Aquameth database, we characterize the European university landscape according to the following dimensions: history/foundation of university, dynamics of growth, specialization pattern, subject mix, funding composition, offer profile and productivity. 相似文献

PurposeThe aim of this study was to evaluate the efficacy of a 17-week, 3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019 (COVID-19) pandemic.MethodsA parallel-group (intervention and control) study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic. The intervention group (n = 38) received a personalized sleep, dietary, and physical activity (PA) program. The control group (n = 41) received no intervention. Outcome measures for sleep, fruit and vegetable intake, PA, and subjective health were measured though an online survey before and after the 17-week period. The changes in outcome measures were used to determine the efficacy of the intervention.ResultsSignificant main effects for time × group were found for International Physical Activity Questionnaire-walk (p = 0.02) and for all other outcome measures (p < 0.01). The intervention group significantly improved in sleep duration (p < 0.01; d = 1.35), Pittsburgh Sleep Quality Index score (p < 0.01; d = 1.14), moderate-to-vigorous PA (p < 0.01; d = 1.44), fruit and vegetable intake (p < 0.01; d = 2.09), Short Form 12v2 physical score (p < 0.01; d = 1.52), and Short Form 12v2 mental score (p < 0.01; d = 2.09). The control group showed significant negative change for sleep duration, Pittsburgh Sleep Quality Index score, and Short Form 12v2 mental score (p < 0.01).ConclusionResults provide preliminary evidence that a 3-component healthy sleep, eating, and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic. 相似文献

The purpose of this study was to determine the effects of short-term normoxic and hypoxic exercise on plasma endothelin-1 and nitric oxide levels, and the relationship of arterial compliance and pulmonary artery pressure to endothelin-1. Seven endurance-trained males completed two incremental and two steady-state exercise tests performed at ventilatory threshold in normoxia and hypoxia (fraction of inspired oxygen = 0.14). Plasma endothelin-1was measured throughout steady-state tests. Arterial compliance using applanation tonometry, plasma nitric oxide and pulmonary artery pressure using Doppler echocardiography were measured before and after exercise. Small arterial compliance and pulmonary artery pressure significantly increased following exercise. There were no main effects of condition or time for plasma endothelin-1and nitric oxide levels. There were no significant relationships between plasma endothelin-1 and arterial compliance or pulmonary artery pressure. In conclusion, mechanisms other than the endothelial system may play a role in the exercise-induced changes in small artery compliance in this study population. Moderate hypoxia and a 30-minute steady-state exercise have limited effects on plasma endothelin-1 in endurance-trained males. 相似文献
