足球运动员训练负荷的生化指标监测

通过对足球运动员实施不同训练负荷方案后心率、血乳酸、血尿素氮的检测与分析研究 ,发现该三项指标随运动负荷强度的增加而增加。因此采用血乳酸、血尿素氮不仅能够客观评定足球训练和比赛的运动负荷强度 ,而且也是控制运动负荷强度以及促进运动疲劳恢复的有效监测指标 ,其方法简单易行 ,从而为教练员加强医务监督、合理安排训练负荷提供科学理论依据。

Efe fathers: one among many? A comparison of forager children's involvement with fathers and other males

The study reported describes Efe (pygmy) forager one-, two-, and three-year-olds' involvement with males. The Efe of northeastern Zaïre were chosen because their social organization allows us to examine hypotheses based on studies in Western, technologically complex societies about the distinctive role fathers play in the lives of their young children. Behavioral observations of Efe children's day-to-day activities with fathers, men and boys were recorded using a focal subject sampling technique (Altmann, 1974). Two behavioral measures were created to capture the extent to which males were involved with children: Social engagement describes males' involvement with children and social attention describes eavesdropping by children on males' everyday activities. Eight one-year-olds, 7 two-year-olds and 8 three-year-olds were each observed for six, one-hour observation sessions that were distributed evenly over the daylight hours. Data were analyzed using the traditional measure of involvement (e.g., adult males) and using a newly developed measure of the involvement of the average individual (e.g., average adult mate). Comparisons at each of the ages showed that fathers were consistently like other men in the extent to which children participated in social activities with them and watched their activities. Only fathers' level of social engagement declined significantly as children grew older. Boys' role relative to other males became increasingly distinctive as children aged. The findings suggest that Efe fathers may not be unique in the same sense assumed by Western study ideals, and raise questions about the special status given to fathers in Western theory and data. The patterning of mate involvement with children is discussed in terms of Efe community life, and in terms of Efe children's developing understanding of their relationship with fathers and other males.     

石油亚砜PSO—Ⅱ与P_(204),P_(507)萃取稀土的研究

分别用P_(204),P_(507),PSO—Ⅱ单独萃取混合氯化稀土,得到了萃取稀土的最佳条件,并对P_(204)与PSO—Ⅱ、P_(507)与PSO—Ⅱ,协同萃取稀土元素进行了初步探讨,发现P_(204)与PSO—Ⅱ,P_(507)与PSO—Ⅱ两者在萃取混合氯化稀土的试验条件下,均无协同效应。

合作学习与课堂参与性——通过合作学习促进英语课堂学生参与性的实验研究

鉴于英语教学重心向语言输出和运用能力的转移,学生在课堂上不再是被动的接受者.富兰克林说(1706-1790):告诉我,我会忘记;教给我,我可能记住;让我参与,我才能学会.因此,怎样让学生成为课堂的主体和积极的参与者成为教师关注的话题.本文通过实证研究调查了利用合作学习法提高英语课堂学生参与性的可能性和可行性,对比分析了实验班和控制班课堂参与状况,并对合作学习的实施提出了建设性的建议.     

道德内化与大学生思想品德教育

大学生思想品德教育的过程,实质上就是将一定社会的思想、道德内化为大学生自身道德品质和信念的过程。道德内化一般是通过角色扮演来实现的。根据道德内化理论,在大学生思想品德教育过程中,我们要把灌输机制与接受机制结合起来;把角色指导与角色训练统一起来;把连续性与系统性结合起来,以使思想品德教育富有成效。
