A Vocabulary Learning Tool for L2 Undergraduates Reading Science and Technology Textbooks

Students of English as a second language who major in science and technology use English-language textbooks to ensure that they can read English materials upon graduation. Research indicates that teachers spend little time helping these students on the linguistic complexity of such textbooks. Vocabulary, grammar, and article structure are elements of this complexity, but to many students, these elements can be akin to locked doors. This study presents MyVLS-Reader, which focuses on unlocking the first of these doors—vocabulary—while assisting in reading. With explicit vocabulary learning, students learn and memorize individual vocabulary, but the context is lost if the depth of learning discards context. In implicit vocabulary learning, students acquire vocabulary through repeated exposure to contexts, but repeated encounters with new words are required. Few e-learning systems combine both vocabulary-learning approaches. MyVLS-Reader achieves such synergy by (1) using a keyword setting to provide context-matched vocabulary explanation while reading and (2) embedding multiple learning choices, such as keyword setting, the review and memorization of explicit vocabulary, and the option to ask instructors. This study includes two rounds of evaluations: (1) an evaluation of the learning achievements of control and treatment groups and (2) a quantitative and qualitative investigation of perceptions regarding the use of MyVLS-Reader. The evaluation results indicate that the treatment group developed a better vocabulary than the control group in significantly less time. The use of MyVLS-Reader also slightly improved higher-order thinking skills. This result suggests that MyVLS-Reader can effective assist students in building their vocabulary while reading.

叶圣陶文体理论的还原与思考

近一个世纪以来,人们对叶圣陶文体理论的片面理解造成了语文教学中文体训练的偏误.实际上,叶圣陶有其明确的文体划分标准,并且分类完善,概念清楚,阐述翔实.还原叶圣陶关于文体的理论,有助于我们认识其指导意义,改变语文教学中淡化文体的做法,把握文体类型和写作类型的相互关系,正确实施对学生的文体训练,切实提高学生的写作能力.     

细菌Ⅱ型分泌系统的研究进展

许多革兰氏阴性细菌,借助于细菌的分泌系统,分泌出毒性因子和效应子,与寄主进行分子交流.革兰氏阴性细菌有5种类型蛋白质分泌系统(Protein Secretion System),即Ⅰ-Ⅴ型.其中,Ⅱ型分泌系统主要以分泌途径转膜蛋白(GSP)基因簇为中心.Ⅱ型分泌系统广泛存在于动、植物致病菌中,它是革兰氏阴性细菌中的常规代谢途径,向细胞外分泌各种蛋白,通过这些蛋白毒性因子破坏寄主细胞,引起组织坏死和病害.研究该系统,将对解析致病蛋白的分泌调控途径,寻找阻断细菌致病蛋白分泌的作用靶标.     

Depressed skull fractures: a pattern of abusive head injury in three older children

OBJECTIVE: To describe a pattern of abusive head injury in a series of children older than 4 years of age. METHODS: A hospital chart review of abused children with skull fractures from 1999 to 2001 was carried out. The clinical features, social background, and subsequent outcome and management are described. RESULTS: An 11-year-old girl and a pair of brothers of ages 7 and 9 were identified. The girl was attacked with a hammer during sleep by her stepmother, who committed suicide shortly afterwards. After craniotomy and intensive care, the child survived her multiple depressed fractures, intracranial bleeding, and brain contusion. Two brothers from a second family were attacked from behind with a hammer by their biological father, who was subsequently found to have undiagnosed schizophrenia. A depressed occipital fracture, without intracranial injury, was found in each child. The elder brother also had metacarpal fractures. Both children recovered without surgical intervention. CONCLUSION: A pattern of abusive head injury was described in older children with depressed skull fractures from blunt injury. The abusing parents were seriously mentally disturbed, and the abusive acts closely resembled child homicide.     

四种英国产香烟烟气中自由基的ESR分析研究

研究了用电子自旋顺磁共振(ESR)法对香烟烟气中的自由基进行分析的样品处理方法及ESR检测方法.对四种英国产香烟样品中的粒相及气相自由基进行了分析检测并对检测结果进行了讨论.结论:大多数英国产的检测样品香烟中,含有1.5～3倍于国产对照香烟样品的气相自由基;而国产对照样品香烟的粒相自由基的含量水平则处于较高水平.实验结果还显示:同品牌的Sobranie香烟中,不同型号样品中粒相自由基含量与焦油含量具有负相关性,但不同品牌则不同;对于检测样品而言,气相自由基的含量与焦油含量有正相关性.     

后大众化下江苏高职院家庭经济困难学生生存状况调查分析

江苏率先进入高等教育“后大众化”阶段,但由于学费一路飙升直接导致家庭经济困难学生数量的增多,根据调查发现这一阶段的家庭经济困难学生不同于以往困难学生,他们在学习和人际交往方面更加自信、自强、主动和务实,但仍然存在经济压力大、动手实践机会少、学生资助效果不理想等等问题,为此,可从思想政治教育、提高其综合素质、完善资助政策体系、改革高职教育发展目标等微观和宏观方面进行思考,以帮助这部分学生能够更好成长、成才,寻找有效资助和帮扶困难学生的政策途径。     

高等教育发展波动现象及作用机理分析

高等教育发展存在着波动现象。教育发展的波动受到包括国家宏观政策的调整与规划、人口状况的变动、经济社会发展状况等外部因素的影响,也受到教育投资产生的乘数、加速以及社会文化环境等内部因素的制约。高等教育发展波动在一定时期内是不可避免的,因此,深入研究高等教育发展的波动问题及其波动机理,有助于促进高等教育平稳和均衡发展,有助于提高教育发展规划预见性和前瞻性,有助于提高教育资源和结构调整的科学性。
