铁、钙、磷元素对波士顿蕨试管苗生长的影响     

兰伟  张伟 《安徽科技学院学报》2015,(1):23-27

将波士顿蕨匍匐茎接种于含铁、钙、磷等元素不同的培养基中培养,探讨铁、磷及钙对波士顿蕨试管苗生长的影响。试验结果表明,一定浓度的铁、钙、磷元素对波士顿蕨的生长有明显的促进作用,但浓度过高会抑制其生长。培养基中不同含量的铁处理中,铁盐含量为13.9~27.8 mg/L效果最佳;不同含量的钙处理中,钙盐含量为220 mg/L效果最好;不同浓度的磷处理中,磷盐含量为170 mg/L效果最好。  相似文献

Is graduate employability the ‘whole-of-higher-education-issue’?     

Thi Tuyet Tran 《Journal of Education & Work》2015,28(3):207-227

Graduate employability has become an issue in Vietnam since many university students do not satisfy the needs of employers. Universities often receive the strongest criticism on the poor employability assets graduates possess. The ill-preparation of university graduates is considered the result of the out dated and irrelevant curriculum in the higher education system, of the traditional teaching methods and the absent of career guidance in most universities. This article, however, aims to challenge this common criticism that university is to blame for the ill-preparation for employment of its graduates. By conducting a qualitative research inviting the voices of both students and employers on the issue, this article wants to address a wider context and circumstance and also the related issues surrounding the transition from university to work of Vietnamese university graduates. It suggests that not only universities, but also students, employers and other related stakeholders (i.e. student’s family, government and educational policy makers) should acknowledge the changes in society, should be aware of the cultural features at work, and should see their responsibility in the process. They all should make an effort to create mutual understanding, to collaborate and to enhance the development of graduate employability in the Vietnamese context.  相似文献

Disability,Stigma and Otherness: Perspectives of Parents and Teachers     

Priya Lalvani 《International Journal of Disability, Development & Education》2015,62(4):379-393

This qualitative study explored the perspectives of parents and teachers in the US with regard to the meaning and implications of disability in the context of schoolling, and of raising a child with a disability. The findings revealed broad conceptual differences in the perspectives of these two groups. Teachers’ beliefs were generally consistent with medical model perspectives on disability as biologically defined. Parents’ interpretations, more aligned with a sociocultural paradigm, were situated in the cultural meanings ascribed to disability and linked with issues of stigma, marginalisation and access. The findings also revealed the existence of master narratives on families of children with disabilities, entrenched in assumptions of pathological functioning and negative outcomes among these families. Implications for professional–family partnerships in the education of students with disabilities are discussed.  相似文献
