Arts integration research has focused on documenting how the teaching of specific art forms can be integrated with ‘core’ academic subject matters (e.g. science, mathematics and literacy). However, the question of how the teaching of multiple art forms themselves can be integrated in schools remains to be explored by educational researchers. This paper draws on data collected at a secondary school in Singapore. The case study analyses how three art teachers, using the idea of ‘space’ as organizing theme, implemented a module of instruction that connected concepts and processes from a variety of art forms (including dance, music, drama and visual arts). We present evidence from curriculum materials, lesson plans, student–teacher classroom interactions and students’ productions. Students were able to reflect upon the importance of space within the arts, analyse the points of convergence and divergence among several art forms, experiment with space and create their own interdisciplinary performances. Our ultimate aim is to provide insights that might inspire art teachers in designing instructional units focused on ‘big ideas’. We suggest that allowing more curricular freedom and providing teachers with adequate structures for interdisciplinary collaboration are key to achieving meaningful levels of integration. 相似文献

Hyperhomocysteinemia has been considered an independent risk factor in the development of stroke. The present study was undertaken
to evaluate serum homocysteine levels in patients with cerebrovascular accidents among the Manipuri population and to compare
with the normal cases. Ninety-three cerebrovascular accident cases admitted in the hospital were enrolled for the study and
twenty-seven age and sex matched individuals free from cerebrovascular diseases were taken as control group. Serum homocysteine
levels were estimated by ELISA method using Axis homocysteine EIA kit manufactured by Ranbaxy Diagnostic Ltd. India. The finding
suggests that hyperhomocysteinemia is associated with cerebrovascular accident with male preponderance, which increases with
advancing age. However, whether hyperhomocysteinemia is the cause or the result of cerebrovascular accidents needs further
investigations. 相似文献

Co-opetition between giants: Collaboration with competitors for technological innovation 总被引：6，自引：0，他引：6

We investigate why and how co-opetition (simultaneous pursuit of collaboration and competition) between large firms occurs, evolves, and impacts the participating firms and the industry. We develop a multi-level conceptual framework by combining literature-based conceptual arguments and insights from an in-depth study of an exemplar case of co-opetition between Samsung Electronics and Sony Corporation. Our study demonstrates that co-opetition is challenging yet very helpful for firms to address major technological challenges, to create benefits for partnering firms, and to advance technological innovation. We also show that co-opetition between giants causes subsequent co-opetition among other firms and results in advanced technological development. Moreover, co-opetition capabilities of firms play an important role in enhancing common benefits as well as in gaining proportionately larger share of the benefits. 相似文献

Chemokine are small, inducible pro-inflammatory cytokines involved in many biological processes, such as migration of leukocytes, atherosclerosis, angiogenesis, tumor growth, and metastasis. Chemokine are also known to influence tumor cell’s activity. Specifically, tumor cells express chemokine receptors in a non random manner suggesting a role of chemokine in metastatic destination of tumor cells. The present study was conducted to determine distribution of (Chemokine receptor 2) CCR2 V64I, Chemokine ligand 2 CCL2 I/D, and CCL2 2518 A>G gene polymorphisms in North Indian population and compare with different populations globally. Polymerase chain reaction (PCR)-based analysis was conducted in 200 normal healthy individuals of similar ethnicity. Allelic frequencies in wild type (GG) of CCR2 V64I G>A were 63 % G; CCL2 I/D 42 % II; CCL2 2518 A>G 40.5 % A. The minor variant allele frequency in our population was as follows: 19.5 % for CCR2 V64I, 35.5 % for CCL2 I/D, 35.3 % for CCL2 2518 A>G. We further compared frequency distribution for these genes with various published studies in different ethnicity. Our results suggested that frequency in chemokine genes exhibit distinctive pattern in India that could be attributed to ethnicity variation. This could assist in high-risk screening of human exposed to environmental carcinogens and cancer predisposition in different ethnic groups. Thus, they signify an impact of ethnicity and provide a basis for future epidemiological and clinical studies. 相似文献

This study is carried out to determine the prevalence of metabolic syndrome (MS) in 148 women between 36 to 65 years using the International Diabetes Federation criteria in the North-Eastern part of India. The prevalence of MS and all its individual components were found to be significantly higher among postmenopausal as compared to premenopausal and perimenopausal women. Various components of MS except waist circumference shows a significant increase and homeostasis model assessment index for insulin resistance also showed significant differences between the three groups. All the MS diagnostic markers (except serum high density lipoprotein) showed a strong positive correlation with MS score among the groups. Further MS score correlated with indicators of insulin resistance evaluated. This study concluded that MS is highly prevalent among North-East Indian postmenopausal women seeking primary health care and its determinant factors related to age and sedentary habits. Thus recognizing and treating MS early with proper intervention can minimize complication. 相似文献

This article investigates conceptually and practically what it means for schools to engage in the practice of continuous improvement. The analysis draws upon prior research and discussion to predict core elements of the practice of continuous improvement in schools. The predictions are then applied to a case study of continuous improvement efforts in a Pakistani secondary school that was involved in a 10-year school–university school improvement partnership. The article concludes with a set of eight empirically based propositions about the practice of continuous improvement schools. 相似文献

Grounded in Vygotsky’s cultural-historical theory, this paper examines how often teachers are involved in children’s imaginative play and discusses their beliefs about their role in supporting children’s imaginative play. To investigate this problem, video (65 hours of digital observations) and interview data (two hours and 30 minutes) of 60 children with 7 teachers from two preschools in Australia were analysed. Using Vygotsky’s [1966. “Play and Its Role in the Mental Development of the Child.” Voprosy Psikhologii 12 (6): 62–76] cultural-historical concept of play, and Kravtsov and Kravtsova’s [2010. “Play in the L.S. Vygotsky’s Nonclassical Psychology.” Journal of Russian and East European Psychology 48 (4): 25–41] conception of ‘subject positioning’ (being inside and outside of the play), it was found that despite the general importance of play, teachers’ involvement in developing children’s imaginative play appears to be minimal. The interviews showed that teachers’ beliefs about their role in children’s imaginative play are directly related to the distance of their physical proximity and understanding of the play narrative being enacted. This paper argues that focusing on teachers’ involvement in children’s play is an important but under-researched dimension of play-based pedagogies in early childhood education. 相似文献

DNA repair capacity is essential in maintaining cellular functions and homeostasis. Identification of genetic polymorphisms responsible for reduced DNA repair capacity may allow better cancer prevention. Double strand break repair pathway plays critical roles in maintaining genome stability. Present study was conducted to determine distribution of XRCC3 Exon 7 (C18067T, rs861539) and XRCC7 Intron 8 (G6721T, rs7003908) gene polymorphisms in North Indian population and compare with different populations globally. The genotype assays were performed in 224 normal healthy individuals of similar ethnicity using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Allelic frequencies of wild type were 79% (C) in XRCC3 Exon 7 C > T and 57% (G) in XRCC7 Intron 8 (G > T) 57% (G) observed. On the other hand, the variant allele frequency were 21% (T) in XRCC3 Exon 7 C > T and 43% (T) in XRCC7 Intron 8 G > T respectively. Major differences from other ethnic populations were observed. Our results suggest that frequency in these DNA repair genes exhibit distinctive pattern in India that could be attributed to ethnicity variation. This could assist in high-risk screening of humans exposed to environmental carcinogens and cancer predisposition in different ethnic groups. 相似文献

The levels of total sialic acid, lipid bound sialic acid and fucose were estimated in the sera of patients with benign and
malignant tumours of breast. An increase was noted in all the three parameters, with a more marked increase in malignancy,
when compared with benign and controls. Consequent to surgery, there was an elevation in the serum levels of the above parameters
than the values prior to surgery and a decline was noted two months after surgery although none of the values reached the
normal range. These results suggest a close association of the glycoproteins with the tumour burden and further signify their
role in early detection and staging of cancer breast. 相似文献
