现代教育技术与大学英语教学质量评估

大学英语是实践性强的学科,其核心目的是培养较好的语言运用能力。大学英语学科性质决定了教学模式应该突出学生自主学习与合作学习,而不是知识讲授。自主学习的教学模式决定了充分运用现代教育技术的必要性。现行教师教学质量评价体系比较粗糙,没有依据学科特点进行细化。大学英语教学质量评估应该从知识讲授型学科的教学质量评估体系中独立出来,把现代教育技术的合理和充分运用作为重要评价指标。     

区域性教育信息资源均衡发展研究：案例比较与优化策略

教育信息资源建设与应用存在区域性差异问题,以广州市越秀、番禺和花都三个区域的部分学校为研究案例,从各区域教育信息资源的软硬件配置、资源利用、教师对资源的认知、资源建设与应用机制4方面进行对比分析。研究指出,为促进区域性教育信息资源的均衡发展,应当优化投入结构和整体配置效益,遵循统一的技术标准建立优质的资源库,拓展与社会力量的沟通合作。     

从国家治理视角谈我国自学考试制度的功能

目前,治理已成为世界各国政府改革的共同议题。由于参与国家治理的主体多元化,使得我们通过自学考试制度来实现对国家的有效治理成为可能。自学考试制度的功能是多方面的,从国家治理的视角看,它能促进国家的稳定与发展,优化国家的资源配置,为国家治理培养大批人才,促进我国的公民教育并有效提高我国的公民素质。

月魄流光——南怀瑾其人其书其事

今年中秋前夕——2012年9月29日的傍晚,南怀瑾先生走了。入夜,天心寥廓,月魄也流光。一南先生是成名于台湾的学者,与北京季羡林先生、香港饶宗颐先生并称当世,被人赞为国学大师。就学问言论,季先生艰涩而深厚,饶先生富丽而广博,南先生平实而奇出。南先生善讲学而多撰述,种数不下三五十,范围大都集中于经藏道法,兼达孔孟老庄,涉及卜易谋略、医药养生、堪舆营造、诗词书画。这与他常情莫测的经历相关。南先生1917年出生于浙江乐清农村,是他父亲中年所得     

Science Letters：IGFBP7 plays a potential tumor suppressor role against colorectal carcinogenesis with its expression associated with DNA hypomethylation of exon 1

Insulin-like growth factor binding-protein-7 （IGFBP7） was obtained from our previous colonic adenocarcinoma （CRC） and normal mucosa suppression subtraction hybridization （SSH） cDNA libraries. By RT-PCR and immunohistochemistry, we found that IGFBP7 was overexpressed in CRC tissue compared to normal tissue. However, our in vitro experiments performed in 10 CRC cell lines showed that IGFBP7 expressed only in SW480 and Caco2 cell lines, which implied an underlying reversible regulatory mechanism. Using methylation-specific PCR （MSP） and bisulfite sodium PCR （BSP）, we found that its expression was associated with DNA hypomethylation of exonl. This was further supported by the in vitro study which showed restored IGFBP7 expression after demethylation agent 5-aza-2＇-deoxycytidine treatment. Correlation analysis between IGFBP7 expression and prognosis indicated that overexpression of IGFBP7 in CRC tissue correlated with favourable survival. Investigation of the functional role of IGFBP7 through transfection studies showed that IGFBP7 protein could inhibit growth rate, decrease colony formation activity, and induce apoptosis in RKO and SW620 cells, suggesting it a potential tumor suppressor protein in colorectal carcinogenesis. In conclusion, our study clearly demonstrated that IGFBP7 plays a potential tumor suppressor role against colorectal carcinogenesis and its expression is associated with DNA hypomethylation of exon 1.     

优秀运动员股四头肌、腘绳肌等速测定正常值的研究

为在运动员选材、安排训练计划、预防运动损伤与康复中使用BIODEX多关节测力及康复系统测定结果提供参考数据,测定了200名男、女运动员及20名男、女大学生的膝关节屈、伸肌群力量.其中共采用了最大力矩等8项指标,为其中6项制定了运动员"评价表格".研究中发现,过去有大腿肌肉拉伤和膝关节损伤史的运动员,并不存在长期性肌力不平衡;股四头肌最大发力角度不同于曲绵域等人过去的报导.提出了某些专项运动员在肌力方面的特点及弱点,可供教练员、运动员参考.     

Health risks with teachers' computer use: some New Zealand observations

With the increased use of computers, and particularly with the increasing use of the Internet in schools, health and education professionals have suggested the need for teachers and students to be ergonomically conscious when using computers. A project was conducted in 1999 to investigate the extent of awareness of health risks associated with computer use in schools of principals, teachers, and administrators of all the primary and secondary schools in Otago and Southland, New Zealand. Results in this study show that although a high proportion of the respondents were aware of these issues, few people took any active preventive measures or participated in any professional development to reduce these health risks. It was also found that nearly two thirds of the school administrators, more than half of the teachers, and nearly 30% of the principals in this study had experienced some kind of health problems related to computer use. Strategies to deal with these issues such as the need for professional development are also discussed in this article.     

革命与恋爱的传播

二十世纪三十年代,随着普罗革命文学运动的兴起和发展,革命救亡的浪潮冲击着女性书写的性别意识,与政治化的革命书写性比,女性的情爱已经变得不值一提。"莎菲"的决绝完成了丁玲跨时代的强力反叛,紧随其后的"革命加恋爱"将个体的解放无可选择地置放于群体解放的浪潮之中。丁玲的革命加恋爱的女性书写表现了女性视角下的生命感受和独特的性别体验,其对当下女性创作仍有一定的影响。
