引入一种新的预测垃圾产量的方法——组合预测方法,该法能够综合利用不同预测方法提供的信息提高预测精度。结合厦门市1996～2008年的垃圾产量,分析不同预测方法的预测精度,并预测5年后的垃圾产量。通过研究发现:单一预测模型中,线性回归法和年增长率法的预测结果偏小,误差较大,灰色理论GM(1,1)的预测结果偏大,误差较小,基本在10%以内;组合预测模型的预测精度高于单一预测模型;厦门市城市生活垃圾年平均增长率约为10%,低于国民生产总值和社会消费品零售总额年平均增长率,高于城镇居民消费性支出年平均增长率。  相似文献

课程改革与政策生态之关联-基于我国基础教育新课程改革的分析     

屠莉娅 《北京大学教育评论》2011,9(3):77-91

本文以我国基础教育第八次课程改革政策的衍生与发展为例,将课程改革政策同具体时空情境下政策生态的四个切面相关联,探讨课程改革政策同经济生态、政治生态、社会生态和教育生态之间的投射性与建构性关系,即政策的发生发展一方面反映政策生态的现实价值导向,另一方面则通过政策生成进行自我表达与建构。本文旨在理解课程改革政策作为反映与建构现实世界的特定方式及其超越理论、政策或实践范畴的深层次内涵与意蕴。  相似文献

An examination of the photographic coverage of sportswomen in the Irish print media: a study of an Irish broadsheet newspaper     

Ciarán Dunne 《Sport in Society》2017,20(11):1780-1798

Building on a large body of extant international research, which has consistently found that sportswomen are underrepresented and marginalized in media reporting, this article presents a study examining the coverage of sportswomen over a four-month period in a major Irish broadsheet newspaper, The Irish Times. The findings, which are based on a data-set of 471 pages, reveal that less than 4% of photographs were of sportswomen. These findings indicate that the Irish situation mirrors international research on the topic and reflects a continuation of the status quo in terms of how sportswomen and women’s sports are (under)valued and (under)reported in the media. The implications of these findings are discussed as well as directions for further study. The article makes a useful contribution to the field given the dearth of research conducted on this topic in Ireland to date.  相似文献   

Perceived benefits and barriers to the use of high-speed broadband in Ireland's second-level schools     

Bryan Coyne  Niamh Devitt  Seán Lyons 《Irish Educational Studies》2013,32(4):355-378

As part of Ireland's National Digital Strategy, high-speed broadband is being rolled out to all second-level schools to support greater use of information and communication technology (ICT) in education. This programme signals a move from slow and unreliable broadband connections for many schools to a guaranteed high-speed connection with technical support. Theoretically, this should allow for behaviours and pedagogies to adapt, incorporating ICT into education. Research shows that integrating ICT into teaching and learning is a gradual process for most teachers and is influenced by a complex mix of socio-technical factors. Our data set consists of survey data from teachers and principals from a sample of second-level schools. The survey collected factual and attitudinal variables including attitudes towards ICT integration, current availability of infrastructure and barriers to ICT use, before schools received high-speed broadband connectivity. We examine the factors influencing teachers’ attitudes to ICT and their perceived barriers in adopting new technologies in their day-to-day teaching. Analysis of this baseline period is essential in an iterative digital strategy, informing future strategies, targeting policy most effectively and achieving policy objectives. While attitudes towards the potential of high-speed broadband and use of ICT are consistently positive across sub groups of schools and teachers, perceived barriers to ICT usage differ.  相似文献   

Does regional disadvantage affect health-related sport and physical activity level? A multi-level analysis of individual behaviour     

Pamela Wicker  Paul Downward  Fernando Lera-López 《European Journal of Sport Science》2017,17(10):1350-1359

This study examines the role of regional government quality in health-related participation in sport and physical activity among adults (18–64 years) in 28 European countries. The importance of the analysis rests in the relative autonomy that regional and local governments have over policy decisions connected with sport and physical activity. While existing studies have focussed on economic and infrastructural investment and expenditure, this research investigates the quality of regional governments across 208 regions within 28 European countries. The individual-level data stem from the 2013 Eurobarometer 80.2 (n?=?18,675) and were combined with regional-level data from Eurostat. An individual's level of participation in sport and physical activity was measured by three variables reflecting whether an individual's activity level is below, meets, or exceeds the recommendations of the World Health Organization. The results of multi-level analyses reveal that regional government quality has a significant and positive association with individual participation in sport and physical activity at a level meeting or exceeding the guidelines. The impact is much larger than that of regional gross domestic product per capita, indicating that regional disadvantage in terms of political quality is more relevant than being disadvantaged in terms of economic wealth.  相似文献

The current paper reports on the outcome of an ongoing action research project at a school for higher-functioning students with Autism Spectrum Disorder (ASD) in Sweden. The overall aim of the study was to develop and evaluate a questionnaire that captures social and individual aspects of classroom learning suitable for use with students with ASD. Interview data is presented on the perceived utility of the questionnaire for understanding and planning classroom instruction for the children with ASD through the eyes of the students’ teachers and their parents, as assessed during an Individual Education Plan meeting. Further, teacher ratings obtained by means of the instrument were found to differentiate a group of students with ASD (n = 10) from a group of typically developing children matched with regard to grade year, word reading ability and receptive vocabulary (n = 10). Implications and future directions are discussed, as are limitations of this pilot study.  相似文献
