大信息平台CIP

任何规模的企业单位、学校、政府部门、军队,产业链以至产业集群,自然界的各种有生命的大小集合体,构成它们的任何信息都应该而且可以组合在一个一体化的大信息平台CIP内,这些信息及其链接是支撑和控制其物理实体和行动的最关键的网络和灵魂.运用这个思想去指导企业信息化建设,企业的信息流、资金流、物流在CIP范围内将处于一种实时、高级有序而又相互关联的状态.充分利用平台的信息有希望达到资源利用的最优化和利润效益的最大化.因此,信息工程界没有理由再去建造信息无法相互沟通的“信息孤岛”.大信息平台CIP的标准将成为国内外公认的信息建设的主要标准.

Teachers’ involvement in high-stakes language assessment reforms: The case of Test for English Majors (TEM) in China

As important stakeholders in language assessment, teachers’ perceptions of language test design and implementation are key factors influencing test impact. This study investigated how English teachers perceived the recent reform of Test for English Majors Grade 4 (TEM4) - a high-stakes English proficiency test targeting English-major undergraduates in China. Furthermore, this study explored the convergence and divergence between teachers’ perceptions of the reform and the intentions of the TEM4 Committee. Findings of this study indicate that teachers in general commented favourably on the revised TEM4 and felt that most of the reform measures were appropriate; however, some divergence between teachers’ perceptions and the intentions of the TEM4 developer was uncovered, particularly in relation to the listening section. This study underscores the importance of soliciting teachers’ perspectives on high-stakes assessment reforms and signals the need for building more effective communicative mechanisms between language assessment providers and stakeholders.     

16开本科技期刊幅面尺寸标准化情况调查

为进一步提高科技期刊幅面尺寸的标准化水平,以GB/T 788-1999为依据, 对808种采用16开本的科技期刊的幅面尺寸进行了调查.结果显示,符合A4型幅面尺寸的期刊仅占被调查总数的49.63%.这一问题应引起期刊编辑出版和管理部门的高度重视.

补充肌酸和抗阻训练对废用性萎缩肌肉GLUT4蛋白的影响

研究了健康大学生外固定腿2周使肌肉愈接近废用性萎缩,并在固定期和恢复期10周过程中连续补充肌酸和抗阻训练,测定股外侧肌葡萄糖转运蛋白4(glucose transporter 4,GLUT4)的变化,并且测定了肌糖原、磷酸肌酸(CP)和肌酸(C)浓度。探讨补充肌酸对骨骼肌废用性萎缩后糖代谢调节机制的影响。研究结果显示:补充肌酸和抗阻训练可以提高废用性萎缩肌肉GLUT4蛋白水平,肌肉吸收葡萄糖和肌糖原合成能力增强。肌肉CP、C和C总浓度在恢复期第3周达到高水平。     

Experimental investigation of external explosion in the venting process

INTRODUCTION Venting technology provides possible protectivemeasures against the effect of explosions. The essen-tial point is to release the high pressure throughproper venting to ensure pressure vessel safety. In acombustion system, when abnormal pressure occursand the venting orifice is opened, a lot of combustiblemixtures venting from the vessel lead to a series ofchanges inside and outside the vessel, and may resultin serious explosion disasters. During the venting proc…     

从“导师”与“学生”的关系看五四新文化运动的思想谱系

“五四”阵营从它扎寨的那一天起就潜存着两种张扬个性观念的歧义，正是“新青年”与导师之间这种对“人”之辅导，培养方向的殊叙，导致了“五四”学生的分化，在英美与欧陆两种以个人为本位的自由主义思想导引下，新青年有了象牙之塔与十字街头的歧路，并在“五四”高潮过后分别走向了赴英美留学和去法俄俭学的道路。
