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。     

工学结合模式在口腔专业教学中的应用研究

大学生社会责任意识现状分析及培养

本文采用自编问卷对289名大学生进行社会责任意识的现状调查。调查表明大学生总体是积极向上的,具有较为强烈的社会责任意识,但其中少数大学生仍存在着家庭责任心不强,对社会发展关注不高等问题。高校应该通过改进传统教育模式,发挥环境育人功能,依托情感教育和价值观教育,增强大学生社会责任的主体意识,提升当代大学生社会责任意识教育。     

高校辅导员在青年大学生中推进马克思主义大众化的作用简

青年大学生对马克思主义理论的掌握程度直接影响着整个社会马克思主义大众化的推进效果。高校推进马克思主义大众化主要依靠思想政治教育工作,而辅导员是这一工作的主力军,是青年学生的人生导师和知心朋友,对推进马克思主义大众化有着重要作用。     

大学生责任感形成的影响因素及教育启示

责任是与一定角色相联系的,角色是责任感形成的逻辑起点。对角色的认知和认同、角色扮演的内在需要、角色实现的能力等是责任感形成的内在因素,外在环境和条件、角色被期待的程度等是影响责任感形成和发展的外在因素。大学生社会责任感的教育应分配每位学生以适当的角色担当,并及时给予其责任行为正反馈。     

我国远程教育研究2013年度进展报告

采用内容分析、元分析和社会网络分析等非反应测量法,从研究主题、研究方法、研究主体、主要共现等多重角度,对2013年度我国远程教育研究进行计量分析和客观述评。远程教与学、管理、资源、学习者、技术与媒体等是年度热点主题,开放大学、交互、MOOCs、移动学习、开放课程、学习资源、网络课程、影响因素、网络学习、精品课程、学习支持服务、调查研究、学习平台、终身学习等是年度热词;观照实践的应用研究是绝对主流,基础理论研究明显薄弱;研究方法的规范应用意识仍需进一步提升,定量研究渐成主流;研究力量分布不均衡,主要集中在经济发达地区和非远程教育机构。
