社会经济形态

科学与怪异

近几十年来,世界上出版了许多奇谈怪论的书,它们披着科学的外衣,实际上是在宣传神灵、迷信与伪科学。……其主要内容不外是外星人已经访问过地球、上帝是宇航员、百慕大三角、飞碟、天外来客、通灵人等等。在这种情况下,美国的一批著名学者,如乔治·O·阿贝尔、艾萨克·阿西奠夫、卡尔·萨根和马丁·加德纳等,为广大读者编写了这本《科学与怪异》。他们在书中首次就一些超自然现象进行了科学的分析。     

Medical students' attitudes toward the anatomy dissection room in relation to personality

Assessment of the personalities of medical students could enable medical educators to formulate strategies for the best development of academic and clinical competencies. In this article, we focus on the experience of students in the anatomy dissecting room. While there have been many attempts to evaluate the emotional responses of medical students to human cadaveric dissection, there has been no investigation into how different personality traits affect the responses. The main hypothesis tested was that there is a relationship between personality traits and attitudes toward the dissection room. For the present study, a group of French medical students (n = 403; mean age 21.3 ± 1.6; 65.3% female) completed a "Big Five" personality inventory and a questionnaire to assess their attitudes in regard to human dissection. The findings are consistent with our hypothesis, in that we found a relationship between reporting anxiety and four of the "Big Five" dimensions (all except openness). The rated level of anxiety was positively correlated with negative affectivity, more strongly at the beginning than at the end of the course. There were significant gender differences in attitudes toward dissection. The findings are discussed in relation to the possibility of preparing students for the dissecting room experience and also in relation to the students' understanding of mortality issues.     

English Premiership Academy knee injuries: lessons from a 5 year study

This study addresses the epidemiology of knee injuries in adolescent males. Data were collected prospectively from 41 Premiership soccer academies over a 5 year period from July 2000 to June 2005. A total of 12,306 player seasons were registered in the U9 to the U16 age categories with a total of 1750 recordable injuries specific to the knee joint. There was a mean incidence of 0.71 (95% confidence interval ± 0.05) knee injuries per player per year, and a median of 17 (inter-quartile range 9-38) training days and 2 (inter-quartile range 1-4) matches missed per knee injury. Knee injuries were found to be most common in the 14-16 year age group. Six hundred and nine (35% of total) injuries were classed as severe resulting in more than 28 days' absence. Injuries were more likely to be sustained in a competitive or match-play environment (862 or 52%) than in training (796 or 48%), and a non-contact mechanism was implicated in 823 (55%) of recorded cases. Peaks in injury numbers were seen in early season and subsequent to the winter break. Sprain was the most common diagnosis recorded, with the medial collateral ligament affected in 23% of all knee injuries. Knee injuries are common in elite youth footballers. In this uninsured age group, it could be argued that earlier medical intervention may reduce long-term damage to the immature skeleton.

阿旃陀洞穴的宝藏

隐藏在印度农村,距孟买东约200英里的30座阿旃陀洞穴,堪与世界七大奇迹并列。这些面积广大的佛教寺院均为2200—1300年以前从险峻的玄武岩悬崖上用凿斧和錾子挖掘而成的。印度其他1000个宗教山洞都无法与阿旃陀洞内那些激动人心的壁画相比,可以说这些阿旃陀洞穴的创     

非洲国家学校教学中的民族语

尽管非洲国家在发展教育中取得了显著成绩,但是在那里有效的教育系统直到现在还是不完备的。这首先表现为由于学生被淘汰和留级造成学校失去质量水平。为了找到解决教育质量问题的方法,非洲国家正在致力于把课程引导到使教育具有非洲特征的轨道上来。而实现这个任务与用地方语翻译教材、用地方语编写教材和教学参考书紧密相关。人们注意到对多数学生用他们所不熟悉的欧洲语言授课是教育质量低、淘汰人数多的原
