20 0 1年 2月 15~ 16日 ,“新版”人类基因组图同时在国际权威刊物《Nature》和《Science》上公布 ,人类的基因总数约有 3.5万个 ,仅比草芥侏儒多出 1万 ,大大出乎人们的预料。很显然人类性状的多样性除基因外 ,还有更深层的原因。以测序为主的“结构基因组学”方法已不能适应生物学的发展 ,解读基因组功能的“功能基因组学”时代已经到来。解读开发基因功能 ,迫切需要更先进的检测方法 ,1991年在美国硅谷诞生的生物芯片技术 ,已成为生物技术开发的热点。1 什么是生物芯片生物芯片是将生物活性物质如细胞、DNA、蛋白质等… 相似文献

Professional transition, employment, and reemployment are major concerns for nations facing adverse economic situations. The employability construct represents a scientific challenge in order to better understand the relationship between the job seekers’ issues and the expectations of the world of work. This paper presents a review of the concept of employability. Three main perspectives (educational and governmental, organizational, and individual) that are not exclusive can be identified. This review highlights the importance of adopting a systemic integrative approach and a wider interpretation of employability. A research agenda to develop the theory and applications of the concept of employability is proposed. 相似文献

This paper describes a series of events observed in an English primary school over the period 1991‐1994. The events are taken as typical examples of school response to an externally1 imposed innovation, namely, the assessment of pupils against the progressive learning scale in the national curriculum.2 The patterns of events occurring in the school are tabulated together with the responses of teaching staff to the change events. The purpose is to inform teacher understanding of the significance of some events in the school's response to change. The claim is that focused reflective practice through reference to change events and types of teacher response are an important contribution to teacher understanding of the meaning of their ‘learning organization’. This practice heightens teachers’ collective awareness of the foci for change within their organization and establishes a vehicle for empowered teacher voice. 相似文献

This paper investigates the claims of action research as an appropriate research methodology for investigating West African education. It suggests that since action research is sensitive to context and is directly relevant to practitioners, it might avoid some of the criticisms that have been levelled at some other methodologies. However, data from Ghana are used to problematize this position. The paper concludes with a discussion of ways in which collaboration between academics and teachers, based on action research, might develop so that both useful knowledge about education in West Africa is derived and practice is improved. 相似文献
