The ‘space’ of friendship: young children's understandings and expressions of friendship in a reception class

The purpose of this study has been to explore young children's understandings and experiences of friendship as these manifested in children's behaviours, in a reception class setting. Drawing on an evolutionary, ecological framework, friendship is seen as not only the expression and further development of social understandings and cognitive advances; more than that, making and maintaining friends is seen as an evolutionary trait and a ‘drive’ to relate to similarly minded others. Through ‘niche picking’, children select the environments and opportunities that suit them in order to develop their dispositions and individual traits. The research employed a participatory design in order to capture the children's views and experiences. It took place in a reception class setting, where children's everyday experiences were observed and discussed with them. The study identified six themes of analysis and offered some suggestions about creating enabling educational environments that allow the ‘space’ for niche construction.     

医改尚未成功,路在何方?

目前我国医疗制度改革尚未取得成功,这与计划经济向市场经济转轨这历史时期及卫生工作的特殊性有关,出现问题,甚至失误,在所难免。提出(1)医改的目的是确保全国人民健康,人人享有医疗保健。(2)把卫生系统推向市场,医疗机构商业化,不是医改的方向。(3)预防为主,健全预防医学制系。(4)国家增加投入。(5)制定公立及私立医院各项制度,保护医务人员的合法权益。(6)加强社区基层医疗机构的建设。

膜表达热休克蛋白70真核表达载体的构建及其对肿瘤细胞的转染

目的构建普遍适合性的膜表达热休克蛋白70(HSP70)的真核表达载体,修饰并建立HSP 70表达并结合在细胞膜表面的肿瘤细胞.方法RT-PCR法从人胚肾中获取HSP 70的cDNA,扩增成带酶切位点的目的基因.选择载体pDisplay,将目的基因插入载体多克隆酶位点中.DNA测序证实后,以脂质体转染的方法,将载体转染到黑色素瘤细胞.用G418抗性筛选获得阳性克隆.结果酶切电泳和DNA测序证实载体构建正确;目的基因的上游带信号肽序列,下游带跨膜序列.RT-PCR产物电泳、Westem Blotting、激光共聚焦显微镜和流式细胞术证实大量HSP 70表达并结合在转染的黑色素瘤细胞膜表面.结论成功地构建了膜表达HSP 70的真核表达载体;转染到黑色素瘤细胞后,细胞膜表面表达丰富的HSP70.转染细胞可以进一步制备新型瘤苗.     

高师地理学科的环境教育

党的十六大所提出的全面建设小康社会，是一个包括政治、经济、文化、环境乃至国民素质的综合概念。它特别要求国民具有健全的环境意识，良好的环境伦理道德和高尚的环境道德行为。作为担负着提高全体国民环境素质和培养中小学环境教育教师和地方环境建设服务三重使命的高师地理学科，面临着其环境教育的课程设置、教材建设和教师队伍建设等不可回避的课题，有必要进行深入探索。
