《野草》主题的佛学解读

《野草》主题隐含着一个与佛学苦、空观相吻合的逻辑层次。在现世苦难的打击下,鲁迅常常觉得唯“黑暗与虚无”乃是“实有”,佛学无常无我价值观促使他走向“绝望之为虚妄,正与希望相同”的空无状态。由空开拓出生命的抗争之路,承担起现世世界扫滞除执、反抗绝望的责任是《野草》哲学的关键。诗文吸收佛教勇猛精进的精神,同时消解了佛教因果轮回的唯心思想。     

Effects of physical activities that induce moderate external loading on bone metabolism in male athletes

Sports characterized by little or moderate weight bearing or impact have a low osteogenic effect. However, the action of such sports on bone turnover remains unclear. The objective of this study was to determine the effect on bone remodelling of physical activities that induce moderate external loading on the skeleton. Thirty-eight male athletes aged 18–39 years (cyclists, n?=?11; swimmers, n?=?13; triathletes, n?=?14) and 10 age-matched sedentary controls aged 22–35 years participated in the study. The study combined measurement of bone mineral density by dual-energy X-ray absorptiometry and bone turnover assessment from specific biochemical markers: serum bone-specific alkaline phosphatase, osteocalcin, urinary type I collagen C-telopeptide and calcium. Compared with the controls and swimmers, adjusted bone mineral density was higher (P?<?0.05) in triathletes at the total proximal femur and lower limbs. No differences in bone mineral density were found between cyclists, swimmers and controls. Compared with controls, osteocalcin was higher (P?<?0.05) in triathletes and swimmers and urinary type I collagen C-telopeptide was higher in swimmers only. Serum bone-specific alkaline phosphatase was lower (P?<?0.05) in cyclists than in all other groups. In conclusion, an osteogenic effect was found only in triathletes, mainly at bone sites under high mechanical stress. Bone turnover differed in athletes compared with controls, suggesting that bone turnover may be sport-practice dependent. Despite some encouraging observations, it was not possible to show that changes in the bone remodelling process were sport-discipline dependent.     

High-Caste Corinthians: Amateurism and the Bloodstock Industry 1945-75

This contribution considers a variety of aspects of the bloodstock breeding world during the three decades following World War Two, focusing in particular on the breeders of thoroughbred horses and the attitudes of those breeders towards their calling. It is argued that even at this late stage of its history, the persistence of the Corinthian amateur ideal, a dogged indifference to the realities of social and economic change, and a high degree of institutional social exclusiveness was in part responsible for the relative decline of what had been, in the inter-war years, the world's pre-eminent bloodstock industry.     

学力调查若干问题探析

自“日本学生学习能力降低了”这一问题提出以来,日本社会各界对实施学力调查的目的、方法等提出了质疑。基于真实性评价的观点,实施学力调查需要慎重考虑诸如学力模式、学力结构以及学力调查的社会环境等多种因素。通过比较分析可以看到,尽管“TIMSS2003”、“PISA2003”和“国研调查2003”三次学力调查所设计的学力模式有所不同,但都是为了更好地实现真实性评价目标进行的创新性尝试。究竟何种学力调查能更好地体现真实性评价,还需要在教育实践中进一步探索。     

Parental Ethnic-Racial Socialization and Children of Color's Academic Success: A Meta-Analytic Review

Increased attention is being placed on the importance of ethnic-racial socialization in children of color's academic outcomes. Synthesizing research on the effects of parental ethnic-racial socialization, this meta-analysis of 37 studies reveals that overall the relation between ethnic-racial socialization and academic outcomes was positive, though the strength varied by the specific academic outcome under consideration, dimension of ethnic-racial socialization utilized, developmental age of the child receiving the socialization, and racial/ethnic group implementing the socialization. Ethnic-racial socialization was positively related to academic performance, motivation, and engagement, with motivation being the strongest outcome. Most dimensions of ethnic-racial socialization were positively related to academic outcomes, except for promotion of mistrust. In addition, the link between ethnic-racial socialization and academic outcomes was strongest for middle school and college students, and when looking across ethnic-racial groups, this link was strongest for African American youth. The results suggest that different dimensions of ethnic-racial socialization have distinct relationships with diverse academic outcomes and that the effects of ethnic-racial socialization vary by both youth developmental levels and racial/ethnic groups.     

Parental racial socialization as a moderator of the effects of racial discrimination on educational success among african american adolescents

This study investigated whether parental racial socialization practices moderated the relation between racial discrimination in school and adolescents’ educational outcomes. Using data from a longitudinal study of an economically diverse sample of 630 African American adolescents (mean age = 14.5) from a major East Coast metropolis, the results revealed that cultural socialization attenuated the effect of teacher discrimination on grade point average (GPA) and educational aspirations, as well as the effect of peer discrimination on GPA. Also, preparation for bias and cultural socialization interacted to make unique contributions to African American adolescents’ educational outcomes. Finally, there was some evidence that teacher discrimination was more detrimental to the academic engagement of African American males than females. Implications for research and practice are discussed.
