在我国出版公益性改革实践十余年后,公益出版已经突破原有体制的限制,成为了出版业共同而广泛的事业.本文首先分析了公益出版面临的新形势,随后在对相关概念进行辨析的基础上,论述了新形势下公益出版的内涵与价值,并对其实现路径进行了讨论.     

我国化学类中文核心期刊开放存取现状与分析

基于2011年版《中文核心期刊要目总览》中收录的化学类核心期刊,搜索并统计分析了我国化学类中文核心期刊开放存取的现状。结果表明:64.00%的期刊在自身的期刊网站实现了开放存取;回溯时间在1980-1989年的期刊数量最多(81.00%),81.25%的期刊回溯至创刊年;多数期刊开放了创刊年至今的全部期刊;75.00%的期刊网上开放全文与印刷版期刊同步,25.00%的期刊网上开放全文滞后于印刷版期刊1期,31.25%的期刊提供了网络预出版的文章;开放全文的格式以PDF格式为主;期刊的检索方式多元化。认为化学类期刊办刊者应加强开放存取理念、缩短开放存取时滞并提高文献检索效果。     

理念与思路的突破:从“馆校结合”到各类教育项目——“科普场馆科学教育项目展评/培育”带来的启示

近10年来,我国科技博物馆教育项目设计水平有了迅速而显著的提升,“科普场馆科学教育项目展评/培育”在其中起到了重要的引领作用。分析其发展过程及优秀案例,会发现“对接《课标》,‘合’而不同”、引进教育学理论与方法,是“馆校结合”项目的两个重要突破点,并带动了科技博物馆教育活动整体水平的提升。从理论与实践看,这两个突破点既吻合了学校与社会对科学教育的需求,又发挥了科技博物馆的资源优势与教育特征,更体现了当代科学教育的发展趋势,并揭示了科技博物馆教育活动今后的发展方向。     

LC框架下的语言学教学及对教师资源整合的探索

研究了发源于美国的LC教学框架和方法及其进行本土化改造后,应用于国内语言学教学实践的情况,并在此框架下探讨教师资源整合的重要内容,希望使其服务于高校的特色发展、教师专业和科研水平的提高,以及创新型、应用型人才的培养.     

车道被占用对城市道路通行能力影响分析

交通堵塞影响现代城市生活,本文针对车道被占用对城市道路通行能力的影响,分析交通视频信息,构建实际通行能力模型,获取事故点横断面实际通行能力的变化。运用 Mann-Whitney 检验法对同一横断面不同车道被占用对实际通行能力的影响进行显著性差异分析;结合车流波动理论知识,建立车辆排队模型,得到排队长度与实际通行能力、事故持续时间以及路段上游车流量间的关系式。     

裕固族作家文学研究的历史回顾与若干思考

传统上,裕固族是一个马背上的游牧民族,人口只有一万余人却有着丰富的文学资源。自20世纪80年代以来,裕固族作家文学的创作与研究都取得了很大成就。纵观20世纪80年代以来裕固族作家文学的创作与研究,可以发现裕固族作家文学经历了八十年代初潮期研究的基本空白,九十年代涨潮期研究的开始活跃,21世纪以来续潮期研究进一步深入的大致轨迹。通过对裕固族作家文学研究历史的回顾,本文探讨了裕固族作家文学创作以及研究的一些缺憾及原因,以期新世纪在新老学者的共同努力下推进裕固族作家文学创作与研究的全面、深入发展。     

适应高职生思想特点的思政教育体系改革初探

高职学生群体思想行为特点主要表现在思想不稳定,整体思想素质不高,个性特长突出,但学习习惯不好。高职目前的思想政治教育从教学内容、教学方法、评价体系等方面未能体现出职业学校学生的思想和行为特性。结合高职学生思想行为特点及高职思政教育现状,提出从高职思政教育的队伍体系、内容体系、方法体系及评价体系等方面进行切合实际的改革,以实现高职思想政治教育的目的。     

Variation in copper and zinc tolerance and accumulation in 12 willow clones: implications for phytoextraction

Willows (Salix spp.) have shown high potential for the phytoextraction of heavy metals. This study compares variations in copper (Cu) and zinc (Zn) tolerance and accumulation potential among 12 willow clones grown in a nutrient solution treated with 50 μmol/L of Cu or Zn, respectively. The results showed differences in the tolerance and accumulation of Cu and Zn with respect to different species/clones. The biomass variation among clones in response to Cu or Zn exposure ranged from the stimulation of growth to inhibition, and all of the clones tested showed higher tolerance to Cu than to Zn. The clones exhibited less variation in Cu accumulation but larger variation in Zn accumulation. Based on translocation factors, it was found that most of the Cu was retained in the roots and that Zn was more mobile than Cu for all clones. It is concluded that most willow clones are good accumulators of Zn and Cu.     

辅助生殖技术学龄前单双胎子代的认知发展存在差异么?(英文)简

Objective： To explore whether there exist differences in cognitive development between singletons and twins born after in vitro fertilization （IVF） or intracytoplasmic sperm injection （ICSI）. Methods： A total of 566 children were recruited for the study, including 388 children （singletons, n=175; twins, n=213） born after IVF and 178 children （singletons, n=87; twins, n=91 ） born after ICSI. The cognitive development was assessed using the Chinese-Wechsler Intelligence Scale for Children （C-WISC）. Results： For all pre-term offspring, all the intelligence quotient （IQ） items between singletons and twins showed no significant differences no matter if they were born after IVF or ICSI. There was a significant difference in the cognitive development of IVF-conceived full-term singletons and twins. The twins born after IVF obtained significantly lower scores than the singletons in verbal IQ （containing information, picture ＆ vocabulary, arithmetic, picture completion, comprehension, and language）, performance IQ （containing maze, visual analysis, object assembly, and performance）, and full scale IQ （P〈0.05）. The cognitive development of full-term sin- gletons and twins born after ICSI did not show any significant differences. There was no significant difference between the parents of the singletons and twins in their characteristics where data were collected, including the age of the mothers, the current employment status, the educational backgrounds, and areas of residence. There were also no consistent differences in the duration of pregnancy, sex composition of the children, age, and height between sin- gletons and twins at the time of our study although there existed significant differences between the two groups in the sex composition of the full-term children born after ICSI （P〈0.05）. Conclusions： Compared to the full-term singletons born after IVF, the full-term twins have lower cognitive development. The cognitive development of full-term singletons and twins born after ICSI did not show any significant differences. For all pre-term offspring, singletons and twins born after IVF or ICSI, the results of the cognitive development showed no significant differences.     

论高校人力资源管理专业复合型师资建设

人力资源管理专业复合型人才培养需要复合型师资,复合型师资建设是高校人力资源管理专业教育发展的重要途径。人力资源管理专业复合型师资的素质包括多学科融合的知识,理论讲授与实践操作相辅相成的能力、教育工作者与企业管理者兼得的态度。高校可以通过不拘一格选用专业教师,鼓励教师向复合型教师发展、优化师资整体结构三个途径建设人力资源管理专业复合型师资。
