广东省顺德区幼儿园教师岗位培训实践探索

为贯彻落实国家有关幼儿园教师持证上岗的规定,广东省顺德区开展了为期两年的幼儿园教师岗位培训工程,对全区尚未领取教师资格的在职幼儿园园长和教师进行全员免费培训。培训着重提高教师考取教师资格的能力,把面授与跟岗见习相结合,在管理上实行项目主办制,按＂分区域、分学历、分专业＂的原则逐期推进。岗位培训是实现教师持证上岗的临时举措,现实中更需要突破现有体制障碍,为幼师考取教师资格提供便利。

Simulation of single DNA molecule stretching and immobilization in a de-wetting two-phase flow over micropillar-patterned surface

We investigate single DNA stretching dynamics in a de-wetting flow over micropillars using Brownian dynamics simulation. The Brownian dynamics simulation is coupled with transient flow field computation through a numerical particle tracking algorithm. The droplet formation on the top of the micropillar during the de-wetting process creates a flow pattern that allows DNA to stretch across the micropillars. It is found that DNA nanowire forms if DNA molecules could extend across the stagnation point inside the connecting water filament before its breakup. It also shows that DNA locates closer to the top wall of the micropillar has higher chance to enter the flow pattern of droplet formation and thus has higher chance to be stretched across the micropillars. Our simulation tool has the potential to become a design tool for DNA manipulation in complex biomicrofluidic devices.     

A capillary dielectrophoretic chip for real-time blood cell separation from a drop of whole blood

This study proposes a capillary dielectrophoretic chip to separate blood cells from a drop of whole blood (approximately 1 μl) sample using negative dielectrophoretic force. The separating efficiency was evaluated by analyzing the image before and after dielectrophoretic force manipulation. Blood samples with various hematocrits (10%–60%) were tested with varied separating voltages and chip designs. In this study, a chip with 50 μm gap design achieved a separation efficiency of approximately 90% within 30 s when the hematocrit was in the range of 10%–50%. Furthermore, glucose concentration was electrochemically measured by separating electrodes following manipulation. The current response increased significantly (8.8-fold) after blood cell separation, which was attributed not only to the blood cell separation but also to sample disturbance by the dielectrophoretic force.     

Associations between health-related physical fitness and obesity in Taiwanese youth

Abstract

This study examined associations between four health-related physical fitness measures and obesity in Taiwanese youth aged 10–18 years. Data from 13,500 school-aged youth were randomly selected from the “School Physical Fitness Database” of Taiwan by sex and age. Variables examined were height, body mass and performance on modified sit-and-reach (flexibility), bent-leg sit-up (abdominal muscular strength/endurance), standing long jump (lower body explosive strength) and distance run/walk (cardiorespiratory endurance). Adjusted logistic regression analyses were performed. Increased odds of being obese with decreased fitness levels were observed for lower body explosive strength and cardiorespiratory endurance in both sexes. The highest odds of being obese was found in the least fit quintile of cardiorespiratory endurance compared with the most fit quintile both in boys (Odds ratio, OR = 10.44; 95% confidence interval (CI), 7.94–13.73) and girls (OR = 5.40; 95% CI, 3.90–7.47). These findings suggest that in addition to cardiorespiratory fitness, lower body explosive strength is also associated with childhood and adolescent obesity.     

中国大学内部规则的科层模式与社会建制

内部规则创建是中国特色现代大学制度转化为治理效能的关键.当前外力推动的内部规则集中式创建呈现出科层模式趋向,导致大学内部组织化程度增强,制约制度优势向治理效能的转化.中国大学内部规则具有组织建制与社会建制二重性,应当在国家治理框架下凸显社会建制属性,同时通过组织建制实现内部规则的个性化和差异化.未来大学内部规则创建要在适当控制规则范畴的同时增强创建和执行规则的能力,综合考虑不同层面规则要素的特殊性以选择合适的规则创建切入点,统筹优化规则所涉管理与决策活动的数量与规则执行效果的可监控性,建立起大学内部规则的动态演变机制,以达成大学内部规则的治理效能.
