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.     

20世纪中国电视剧发展的分期及特征

从20世纪50年代到20世纪末,中国电视剧经历了一个由诞生到发展、繁荣的艰难历程。20世纪80年代中期以前的20多年可分为初创期、停滞期、复苏期和发展期;20世纪80年代中期到20世纪末可分为成熟期和繁荣期。从中可以见出其受社会外部影响和内部规律制约的情形,有助于推动中国电视剧艺术的进一步繁荣。     

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。
