基于道路网络分析技术的耕地细碎化测度模型改进   总被引：4，自引：0，他引：4  

葛玉娟  赵宇鸾 《资源科学》2019,41(4):766-774

为了提高耕地细碎化测度结果的准确性,运用GIS网络分析技术改进了测度模型。首先,综述了耕地细碎化的内涵和现有测度方法不足,提出实际道路网络是耕地细碎化程度测定中不可或缺的指标。其次,依据耕地细碎化的内涵,选取基于道路网络的农户地块道路通达性指数、农户地块面积指数、农户地块形状指数3个指标,构建了新的耕地细碎化测度模型。最后,采用新模型对典型村的耕地细碎化程度进行实证分析,证实该模型的有效性,并对比分析农户到其耕作地块的直线距离与道路网络距离两种距离测度方式下的耕地细碎化差异,表明与道路网络距离相比直线距离低估了耕地细碎化水平。改进的测度模型对深化研究耕地细碎化及其对农业生产投入—产出的影响等研究具有积极意义。  相似文献   

认知凸显视角下的与格换位结构研究     

杨江锋 《天水师范学院学报》2012,32(2):68-73

使用基于语料库的研究方法,依据“语言形式的特性——心理处理所需的努力程度——凸显程度的大小”的思路,对与格换位结构中目标和受事在可及性理论所包含的核心参数的表现上进行了分析.单因素和多因素的分析表明,相关因素都能很好地判别出DO和PO结构.与格换位结构现象的形成本质上是由目标和受事所具有的凸显程度不同造成的.这种凸显是目标和受事可及性程度高低竞争的最终产物.具有不同可及性程度的目标和受事竞争的最后结果是一方比另一方更为凸显.在DO结构中目标得到凸显,而在PO结构中受事得到凸显.  相似文献

The effect of epistemic fidelity and accessibility on teaching with physical materials: A comparison of two models for teaching decimal numeration     

Kaye Stacey  Sue Helme  Shona Archer  Caroline Condon 《Educational Studies in Mathematics》2001,47(2):199-221

Multi-base arithmetic blocks (MAB) are the most frequently used physical materials for teaching about decimal numbers, despite published reservations about their appropriateness. This paper presents an alternative, LAB (linear arithmetic blocks) and compares the two materials on the basis of epistemic fidelity and accessibility for students. Two teaching experiments involving 30 matched students indicated that LAB is considerably more accessible for students, and identify three contributing factors (LAB modeling number with length rather than volume, MAB incorporating an apparent dimensional shift and having prior use). Use of LAB was associated with more active engagement by students and deeper discussion. Epistemic fidelity is critical to facilitate teaching with the models, but we attribute the enhanced classroom environment to the greater accessibility of the LAB material. Further research is warranted, so that teaching of mathematics with physical materials can be improved. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献   

Methodologies for the inclusive education of students with severe visual impairment or blindness / Metodologías que garantizan la inclusión educativa de estudiantes con discapacidad visual grave o ceguera     

Isabel Serrano  Ascensión Palomares  Catherine Kostich 《Cultura y Educación》2016,28(2):359-377

The aim of this paper is to present the educational experiences that have been implemented in the community of Madrid (Spain) with students with severe visual impairment or blindness. We highlight why and how the new educational policies being implemented have achieved the genuine inclusion of these students in line with European educational objectives. The study was carried out during the academic years 2010–11 to 2015–16. We conclude that the educational inclusion of students with visual impairment becomes a reality upon the effective participation of two specialized teams, namely, the educational psychologists for young children (divided in stages from zero to three years and from four to 12 years of age) and the educational specialists in visually impaired children. This constitutes a prime example that can be extended to other contexts and other disabilities. It becomes evident that, to be effective, inclusive education requires a joint and coordinated response from all professionals involved in the education process.  相似文献

‘I want to keep up with the younger generation’ - older adults and the web: a generational divide or generational collide?     

《International Journal of Lifelong Education》2012,31(5):566-578

ABSTRACT

This paper considers the social significance of digital technologies in older adults’ lives by exploring the impact the web has on their lived experiences. The study of digital literacies and digital cultures is mostly focused on youth, thus paying limited attention to older adults’ engagement with the web. With this paper, we aim to contribute to under-theorised debates of older adults’ digital experiences beyond generalisations of generational and/or digital divides. Focus groups interviews with older adults enrolled in sessions on digital literacies were used to get insight into this cohort’s online experiences. The findings revealed that older adults’ key motivation to become digitally literate was driven by a desire of remaining relevant in a contemporary world, in other words, of cultivating their identity as active citizens in a digital society. We offer considerations and reflections on the findings through the application of the works of Karl Mannheim to the phenomenon investigated.  相似文献   

论政府在精神卫生服务体系建设中的责任边界     

刘飞跃  肖水源  曾望军 《湖南师范大学社会科学学报》2012,(1):23-27

政府的本质属性和精神卫生服务产品的特殊性,决定了政府应承担精神卫生服务体系建设的主要责任。然而,因我国政府在精神卫生服务体系建设的责任边界不明,导致现行精神卫生服务体系难以应对21世纪我国精神卫生问题面临的严峻挑战。依据市场体制发展规律和政府治理之道,转型期的我国政府在精神卫生服务体系建设中应承担的主要责任包括:提高精神卫生的知晓率,健全精神卫生人权法规,制定精神卫生人才培养规划与政策,把精神卫生医治与康复纳入社会保障体系,根据地域、人口密度与发病率等的关系和现代组织设计理论重构精神卫生服务网络与合理配置精神卫生资源等。  相似文献   

CatDoc HackDoc: Tools and Processes for Managing Documentation Lifecycle,Workflows, and Accessibility     

《Cataloging & classification quarterly》2012,50(7-8):463-495

Abstract

Documentation of local policies, workflows, and procedures is an important activity for cataloging and metadata units. But creating and maintaining documentation is a huge task that is not always a high priority. Librarians at the University of Minnesota Libraries planned a documentation hackathon, CatDoc HackDoc, with three primary goals: to update a large amount of documentation quickly, to apply accessibility best practices to all documentation, and to bring new staff into the documentation workflow. This article describes the event’s planning process, structure, and outcomes, and offers guidance on how others can adapt the CatDoc HackDoc model in their own organizations.  相似文献
