Since accurate decisions are required for effective management, much research has focused on information systems that support decision making. Recently, this research has engendered frameworks, such as the management support system (MSS), that are designed to provide comprehensive and integrated support for the decision making process. Few, if any, studies have empirically measured the effects of these frameworks on decision making. This article offers empirical evidence on MSS effectiveness. It overviews the decision making process, presents an MSS for supporting the process, and assesses the influences of the MSS on the process and outcomes of health care decision making. The paper also examines the implications of the analyses for information systems research and health care practice. 相似文献

Measuring academic growth, or change in aptitude, relies on longitudinal data collected across multiple measurements. The National Educational Longitudinal Study (NELS:88) is among the earliest, large-scale, educational surveys tracking students’ performance on cognitive batteries over 3 years. Notable features of the NELS:88 data set, and of almost all repeated measures educational assessments, are (a) the outcome variables are binary or at least categorical in nature; and (b) a set of different items is given at each measurement occasion with a few anchor items to fix the measurement scale. This study focuses on the challenges related to specifying and fitting a second-order longitudinal model for binary outcomes, within both the item response theory and structural equation modeling frameworks. The distinctions between and commonalities shared between these two frameworks are discussed. A real data analysis using the NELS:88 data set is presented for illustration purposes. 相似文献

ABSTRACT The importance of intercultural competence in today’s global economy is evident. Achieving intercultural competence, however, has no single formula. This study explored the variables impacting intercultural competence development. Through a systematic literature review, it identified 48 scholarly sources, 11 unique variables and two sub-variables impacting intercultural competence development. The impact of programme characteristics was found to be significant across the board, while the impact of demographic factors was harder to predict. The findings of this research inform scholars, educators and practitioners of the most effective ways to design intercultural experiences and help participants maximize their learning at home and abroad. 相似文献

Dietary and lifestyle factors have been shown to have a profound effect on paraoxonase-1 (PON1) activity. Cigarette smoke has been shown to inhibit its mass and activity where as resveratrol has been shown to enhance it. We exposed hepatoma derived cell line (HepG2) to resveratrol and nicotine in varying doses and measured PON1 enzymatic activity and PON1 gene expression. In addition, total protein content of HepG2 cells was also measured. Resveratrol in a dose of 15 μmol/l or above significantly increased the PON1 enzyme activity (p > 0.001) where as nicotine in a dose of 1 μmol/l or higher significantly reduced it (p < 0.05). The resveratrol in this dose also enhanced the PON1 gene expression whereas nicotine decreased it as compared to controls. However, the protein conent of cells was not changed suggesting that they were not cytotoxic in the doses used. Till date the antioxidant vitamins have shown disappointing results against LDL oxidation and cardiovascular protection. However, the effect of resveratrol on PON1 gene expression and activity was significant, suggesting increase in PON1 activity and enhanced gene expression may be its alternative mechanism for offering protection against cardiovascular disease and may be an potential pharmacological agent which can be used for this. 相似文献

ABSTRACTAcross the globe, the Salamanca Statement has provided the strongest impetus for drawing attention to the education of some of the most marginalised groups. In India, it has had a significant and specific impact on the provision of schooling opportunities for children with disabilities. This paper provides a critical analysis of key developments in national policies and programmes and how these have shaped provision at the classroom level. Drawing on Nancy Fraser’s conception of justice as an analytical tool, efforts towards inclusive education in India are explored through the interlinked ideas of redistribution, recognition and representation. Over the last two decades, there has been a significant increase in the numbers of children with disabilities being enrolled in schools, driven by factors including, positive legislation and the increased provision of aids and appliances, etc. However, little attention has been paid to the quality of teaching and learning, experienced by children with disabilities. Instead, efforts remain focused on assimilation into a mainstream system fraught with different challenges. Despite these issues, India is a powerful example of how the vision of inclusive education, as outlined in the Salamanca Statement, is feasible, especially if efforts build on contextual realities. 相似文献

This article explores developments towards inclusive education being undertaken in some schools in India. Drawing on data collected through interviews with key professionals working in schools and classroom observations, the study focused on the practices and experiences of professionals involved in these efforts. Findings suggest that these schools had provided access to children who would otherwise have been denied admission to the mainstream due to their disabilities. However, these children remained the ‘included’ children and did not necessarily become a part of the classroom. Thus, evident in these schools were a range of exclusionary practices that continued to exist alongside efforts towards inclusion. I therefore argue that there is not only a need to provide stakeholders with the knowledge and skills for developing inclusive teaching practices, but also a need to challenge existing values, beliefs and attitudes to ensure the full participation of all children in the curriculum and culture of their school setting. 相似文献

This article examines education of children belonging to marginalised groups, with particular reference to children with disabilities, within the Indian context. Based on an analysis of post‐independence Government documents, various educational provisions made available for children with disabilities are discussed. It explores the Indian Government’s focus on the development of special schools, its efforts towards integration, and the more recent emphasis on inclusive education. Furthermore, it attempts to elucidate “inclusive education” as understood in various official documents. The article concludes by arguing for a need to develop a contextual understanding of inclusive education that is reflective of current educational concerns in India. 相似文献
