Grammar is an important aspect of English language pedagogy in China and is taught as a subject of study in Chinese primary and high schools. Despite studying grammar for several years, however, high school graduates find it difficult to express their ideas in English especially when they are asked to write essays at university. This article reports a study that investigates students' views regarding the study of grammar when contextualized to their writing courses. It was found that students appreciate contextualized study of grammar as opposed to isolated learning of grammar using memorization, drills, and practices. The study suggests that a shift in the aims and methods of teaching English in high schools is necessary if students' preferences, which are consistent with research literature in second language teaching, are to be taken into consideration.  相似文献

Serum total cholesterol and triglyceride levels were estimated in 45 dilated cardiomyopathy (DCM) patients and were compared with 31 healthy controls. The total serum cholesterol (215±50 mg/dl) and serum triglyceride (162±76 mg/dl) levels in DCM patients did not show any significant changes as compared to normal controls. The cholesterol and triglyceride and the individual lipoprotein fractions, viz HDL, VLDL, LDL and chylomicrons were analysed in 10 patients. The values did not differ significantly when compared to those of controls. These findings suggest that serum lipids may not play a role in the antietiopathogenesis of DCM.  相似文献

This paper argues for the need to adopt a more participatory and research-based approach to teacher development in India. Drawing on the experiences of a participatory teacher educator development project in three States, we discuss processes of developing a democratically orientated qualitative research team to work with teachers and teacher educators, highlighting the interplay between their education and socialisation and the demands of the methodology. In the second part of the paper, aspects of developing collaborative action research projects with teacher educators in the context of District Institutes of Education and Training are discussed. Both these approaches require the development of autonomy and critical reflexivity, and although there are tensions in this process, these emerge as vital components of developing a more democratic approach to teacher education.  相似文献

Unstable angina is a critical condition of heart resulting from narrowing of vessels supplying blood to heart. Ischemia of the myocardium leads to oxidative stress and severe tissue damage. The objective of the present study was to determine the effect of l-arginine administration on the oxidant–antioxidant homeostasis which otherwise gets imbalanced in patients with cardiovascular diseases. The results obtained, show improvement in the oxidant–antioxidant levels of the subjects upon incorporation of l-arginine. Our findings suggest that supplementation of l-arginine along with regular anti-anginal therapy may be beneficial to the patients of unstable angina.  相似文献

This study provides an overview of the research output of Jawaharlal Nehru University, New Delhi, India, in terms of number of publications contributed by faculty members and researchers. The study analyzes bibliometric indicators of published research of Jawaharlal Nehru University as indexed in the Web of Science. There were 5,007 research publications from Jawaharlal Nehru University in the four decades from 1971–2010 (70s; 80s; 90s; and 2000s). The study noted encouraging trends in collaborative research work with multiple-authored research papers. International collaboration in research was also observed among the faculty members and researchers. English was the predominant language of communication. The social scientists and humanists of Jawaharlal Nehru University publish books which are not indexed in the Web of Science. Similarly, research work published in regional languages or published in national level journals are seldom included in the Web of Science. It suggests that research needs to be done by collecting data from the Indian Citation Index and books published by the researchers in order to get an accurate and consolidated picture of the research output of the university.  相似文献

Online open source software platforms, such as Sourceforge.net, play a vital role in creating an ecosystem that enables the creation and growth of open source projects. However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives—voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study 1 investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.  相似文献

This study was conducted to find out the level of oxidative stress and effect of supplementation of vitamin C, D and Calcium on levels of SOD, serum and urinary fluoride in children residing in endemic fluorosis area. For this the fluoride belt of Jaipur district was selected. The parameters selected were Super oxide dismutase, serum fluoride and urinary fluoride. The study was conducted on one hundred children, selected from four areas (25 from each area) consuming water containing 1.2, 2.4, 5.6 and 13.6 mg/l of fluoride. Drinking water fluoride, serum and urinary fluoride were measured by Ion selective electrode method. Serum SOD by Xanthine oxidase method using kit of Ransod (kit cat. No. SD125). The post treatment values showed a significant reduction in serum fluoride and SOD. Urinary fluoride levels increased significantly in post treatment stage. The results revealed a normal SOD levels in all groups but an increasing trend was observed with increasing fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C showed a significant reduction in serum fluoride and SOD and increase in urinary fluoride. A high positive correlation between pretreatment and post treatment group was observed in serum fluoride, SOD and urinary fluoride (P < 0.05). The study indicated an increasing oxidative stress in cases of fluorosis with increasing drinking water fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C resulted a significant reduction in serum fluoride and SOD and increase in urinary fluoride.  相似文献

We describe a case of poorly differentiated adenocarcinoma of stomach, which did not present typical symptoms of gastrointestinal malignancy on first visit. The patient, a 62 year old smoker presented with shortness of breathe and pain in right lumbar region with no history of fever. Bone scans revealed multiple hot spots in skull, sternum, lumbar vertebrae and both iliac crests. A series of tumor markers were ordered which include PSA, CEA, CA19.9, CA 72.4 and AFP. Serum PSA and AFP concentrations were within normal range. Serum CEA and CA 72.4 were raised significantly. Markedly elevated levels of serum CA19.9 were found (>45000 U/ml) in this patient. CT chest and bronchoscopic examination ruled out the possibility of cancer lung. Upper GI tract endoscopy was done to find out lesion in GI tract. An ulcerative lesion was found in lesser curvature of stomach. Histopathological examination of endoscopic biopsy revealed a poorly differentiated adenocarcinoma of stomach. An unusually high serum CA19.9 (>45000U/ml) in case of gastric carcinoma has not been reported earlier.  相似文献

Ovarian cancer has been emerged as a most common and lethal gynecological malignancy in India. High serum insulin and low adiponectin have been associated with increased risk of ovarian cancer. But their role in development of ovarian cancer is conflicting and little evidence is available. We aimed to evaluate blood levels of insulin and adiponectin in epithelial ovarian cancer (EOC) patients and their association with the risk to develop EOC. The study included following three groups; Group 1: fifty cases of cytohistopathologically confirmed cases of EOC, Group 2: fifty age matched cases of benign ovarian conditions and Group 3: fifty ages matched healthy controls with no evidence of any benign or malignant ovarian pathology as ruled out by clinical examination and relevant investigations. Cytohistopathologically confirmed and newly diagnosed cases of EOC and benign ovarian cancer were included in this study. The median value of fasting serum insulin was significantly high (15.0 µlU/ml, P = 0.02) and adiponectin were significantly low (5.1 µg/ml, P < 0.001) in ovarian cancer patients compared to benign ovarian tumors and healthy controls group. A significant increase risk of ovarian cancer was found in high tertile (≥ 18.7 µlU/ml) of serum insulin level (OR = 2.7; 95% CI = 1.00–6.67, P = 0.04) and lower tertile (≤ 5.45 µg/ml) of adiponectin level (OR = 3.2; 95% CI = 1.10–9.71, P = 0.03). High serum insulin level and low adiponectin levels were significantly associated with increased risk for development of ovarian cancer.  相似文献

The purpose of this paper is to provide a reconnaissance of major academic libraries located in Australia, Canada, the U.K. and U.S.A. that have embraced Web 2.0 tools for enhancing library services. The research is based on a survey of websites of 277 university libraries. The checkpoints used for this evaluative study were given by Nguyen (2008) for evaluating various Web 2.0 tools. Additional checkpoints were arrived at after visiting and browsing the various sites. The findings of the study acknowledge the strength of Web 2.0 tools in improving library services for users. Really Simple Syndication (RSS), Instant Messaging (IM) and blogs are popular in academic libraries. The paper concludes by offering best practices for implementing Web 2.0 tools in academic libraries.  相似文献
