The student population across world is increasingly reflective of diverse cultures, religions and ethnicities. This rich diversity may become a challenge for educational leaders, teachers, and policy‐makers in the absence of an understanding of diverse sources of knowledge people draw on for directing their beliefs and daily practices. This paper explores the multi‐ethnic context in Britain with a focus on Muslim students in English secondary schools, and argues for drawing on diverse ethnic knowledge sources to inform and enrich approaches towards managing diversity. It discusses the concept of Adab derived from Muslim ethics and philosophy, and debates possible contributions of such conceptual adaptations towards improving educational engagement and performance.  相似文献

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.In this series of articles, the authors discuss various phenomena in fluid dynamics, which may be investigated via tabletop experiments using low-cost or home-made instruments. The sixth article in this series explores crystalline defects and motion of dislocations using bubble rafts. Materials  相似文献

Plexiform lesions (PLs), which are often accompanied by perivascular infiltrates of mononuclear cells, represent the hallmark lesions of pulmonary arteries in humans suffering from severe pulmonary arterial hypertension (PAH). Endothelial progenitor cells (EPCs) have been recently implicated in the formation of PLs in human patients. PLs rarely develop in rodent animal models of PAH but can develop spontaneously in broiler chickens. The aim of the present study was to confirm the presence of EPCs in the PLs in broilers. The immune mechanisms involved in EPC dysfunction were also evaluated. Lungs were collected from commercial broilers at 1 to 4 weeks of age. The right/total ventricle ratios indicated normal pulmonary arterial pressures for all sampled birds. Immunohistochemistry was performed to determine the expressions of EPC markers (CD133 and VEGFR-2) and proangiogenic molecule hepatocyte growth factor (HGF) in the lung samples. An EPC/lymphocyte co-culture system was used to investigate the functional changes of EPCs under the challenge of immune cells. PLs with different cellular composition were detected in the lungs of broilers regardless of age, and they were commonly surrounded by moderate to dense perivascular mononuclear cell infiltrates. Immunohistochemical analyses revealed the presence of CD133+ and VEGFR-2+ cells in PLs. These structures also exhibited a strong expression of HGF. Lymphocyte co-culture enhanced EPC apoptosis and completely blocked HGF-stimulated EPC survival and in vitro tube formation. Taken together, this work provides evidence for the involvement of EPCs in the development of PLs in broilers. It is suggested that the local immune cell infiltrate might serve as a contributor to EPC dysfunction by inducing EPC death and limiting their response to angiogenic stimuli. Broiler chickens may be valuable for investigating reversibility of plexogenic arteriopathy using genemodified inflammation-resistant EPCs.  相似文献

This article examines how non-governmental organizations create resources and spaces for girls and women’s education and empowerment in China, India and Pakistan – in the context of global expectations and local state relations as well as cultural norms. We examine the dynamics that foster female empowerment associated with educational attainment. Analysis showed that the five NGO’s responses to enabling and constraining local needs and demands gave rise to productive friction that activated positive development. We conclude that engaging local individuals as managers, teachers or facilitators who can negotiate with international actors and with the state is an effective foundation for maintaining a balance between being accountable to local contingencies and norms and to global social justice principles of the projects. These models indicated that “effective scale” might better be defined as a collaboration between the local and global, rather than “scaling up” in size.

International NGO partnerships with several of state organizations and local leadership can be a catalyst for fundamental change, subject to dynamic engagement with productive friction that activates educational empowerment and social change.  相似文献

There has been much debate concerning the pros and cons of special and mainstream education for young people with a disability. This paper adds data to this debate by reporting the educational experiences of 20 high-achievers with congenital disabilities who live in the United Kingdom and were born between 1950 and 1970. It presents personal accounts of the high-achievers' perceptions of how their education, which was either purely in special schools, in mainstream schools or a combination of both, had influenced their transition to adulthood. While those who attended special school considered it to provide a supportive environment that permitted the cultivation of their personalities without the constraints of non-disabled barriers, many others thought it prevented them as disabled children from interacting with non-disabled peers, thus inhibiting social integration between the disabled and non-disabled world. This was the main perceived advantage of mainstream education although problems of physical access meant that some choices were out of reach. The findings highlight how both special and mainstream education can be compatible with career success of individual disabled people. The paper implies that a combination of the two systems may be needed to facilitate disabled students to develop psychologically, socially and cognitively at the rate of their non-disabled peers, and proposes that link schools and partial integration could contribute to the achievement of such goals.  相似文献
