An evaluation framework for cross-lingual link discovery     

Ling-Xiang Tang  Shlomo Geva  Andrew Trotman  Yue Xu  Kelly Y. Itakura 《Information processing & management》2014

Cross-Lingual Link Discovery (CLLD) is a new problem in Information Retrieval. The aim is to automatically identify meaningful and relevant hypertext links between documents in different languages. This is particularly helpful in knowledge discovery if a multi-lingual knowledge base is sparse in one language or another, or the topical coverage in each language is different; such is the case with Wikipedia. Techniques for identifying new and topically relevant cross-lingual links are a current topic of interest at NTCIR where the CrossLink task has been running since the 2011 NTCIR-9. This paper presents the evaluation framework for benchmarking algorithms for cross-lingual link discovery evaluated in the context of NTCIR-9.  相似文献

Accounting for structure and agency in ‘close-up’ research on teaching,learning and assessment in higher education     

Paul Ashwin 《International Journal of Educational Research》2008,47(3):151-158

This paper examines research into teaching, learning and assessment (TLA) in higher education in terms of structure and agency. It argues that although issues of structure and agency are seen as crucial in social theory, they are very little discussed in research into TLA in higher education and that a consideration of structure and agency raises some important questions about this research and the quality of the explanations that it generates. It is therefore time to reconsider this research from the standpoint of structure and agency so that more sophisticated approaches to researching, and generating explanations of, teaching, learning and assessment in higher education can be developed.  相似文献   

Assessment for learning: a catalyst for student self-regulation     

Eleanor Hawe  Helen Dixon 《Assessment & Evaluation in Higher Education》2017,42(8):1181-1192

The development of students as lifelong, self-regulating learners is a valued outcome of higher education. To this end, the current project investigated how students in an undergraduate course experienced and responded to a teaching–learning environment where they were expected to take responsibility for their learning. The pedagogic environment of this course was grounded in strategies and activities associated with assessment for learning (AfL). As such, students were expected to participate in activities that provided them with opportunities to exercise control over their learning. Data gathering comprised individual semi-structured interviews and the collection of artefacts. Findings indicated goals helped students know where they were going; exemplars provided insights into what was expected and what constituted quality work; course activities elicited evidence of learning; dialogic interactions around these generated feedback about understandings and progress; the evaluation of exemplars developed evaluative knowledge, skill and expertise; peer review and feedback provided an authentic context for evaluation and monitoring of works-in-progress. It was concluded that, while each of the AfL strategies contributed to student self-regulation, the full impact of AfL as a catalyst for self-regulated learning was realised in the cumulative and recursive effect these strategies had on students’ thinking, actions and feelings.  相似文献   

山东省禹城市粮食生产资源利用效率评价   总被引：3，自引：1，他引：3  

吴绍洪  戴尔阜  靳京 《资源科学》2007,29(1):21-26

粮食生产资源利用效率研究是实现粮食稳产、高产的前提，也是保障国家粮食安全的理论基础。对不同条件下的作物生产潜力准确估算和适宜的资源利用效率评价是粮食生产资源利用效率研究的核心内容。本文采用PS123作物生长模型进行作物生产潜力计算，根据山东省禹城市实际状况，确定了模型输入参数，计算了研究区玉米、小麦和大豆的光合、光温、气候和气候－土壤生产潜力，采用作物结构订正计算区域粮食生产潜力。考虑粮食生产中光热资源、水资源、土地资源、社会经济资源等方面，从准则层和因子层两个层面构建了粮食生产资源利用效率评价模型，确定了各评价因子的目标值和权重，对禹城市粮食生产资源利用效率进行评价。研究结果表明：　①山东省禹城市光合生产潜力52 784kg/hm²，光温生产潜力11 023kg/hm²，气候生产潜力8 377kg/hm²，气候-土壤生产潜力6 450kg/hm²，对这3种作物的实际产量进行结构订正得到该市1999年～2001年粮食平均现实生产能力为6 244kg/hm²，禹城市粮食生产潜力较大；　②制约粮食生产稳产、高产主要自然因子为水资源的不合理利用，劳动生产率、化肥利用率和产投比的低下是主要的社会经济限制因子。根据不同的限制性因子，本文提出了单项资源利用技术改进措施。  相似文献

Developing a template for National Child Protection Index Reports     

Ager A  Stark L  Chu E  Dewan S  Boothby N 《Child abuse & neglect》2011,35(12):1002-1008

Objectives

What impact does the strengthening of child rights have on the experience and circumstances of children? CRC General Comment 13 emphasizes that defining measurable targets for improvements in child protection is a key element of efforts to strengthen child rights and well-being across the world. This paper describes an attempt to identify key domains relevant to such mapping of child protection indicators, and the feasibility of collecting data—from existing data sources or otherwise—to complete a “National Child Protection Index Report” summarizing achievements and concerns at a national level.

Methods

A process of inter-agency consultation was facilitated by the CPC Learning Network to establish a template for the Index Report. The template was modeled on that used for the “Countdown to 2015” maternal, neonatal and child health initiative, aiming to capture indices not only of key protection risks but also implementation and coverage of key protection measures. The work drew on indicator development and policy initiatives by a number of international child protection agencies. The template developed was used as a basis to pilot national data collection in Indonesia and, at a sub-national level, in northern Uganda.

Findings

The template provides a concise summary of protection issues of relevance to a broad range of constituencies, global and national. However, in the pilot settings, existing routine data collection was inadequate to effectively populate a large proportion of indicators. Mechanisms of collating findings from discrete assessments—another potential source of data for completion of the index report—were also generally underdeveloped.

Practice implications

In settings where state infrastructure allows the collection and analysis of routine data in such domains as health and economic activity, such efforts should be extended to the child protection sector. Discrete assessments by governmental or non-governmental agencies also provide significant potential for more effective sharing and collation of information. National Child Protection sub-clusters or equivalent structures can play an important role in facilitating both of these processes.  相似文献

公权力拥有者主张私权利的限制与评价——从重庆公安局支持民警“双起”维权谈起     

《中国媒介传播维德守法状况及评价报告》课题组 《国际新闻界》2011,(2)

本文从双起事件入手,探讨了公权力组织及公权力人物与媒介的关系,并就公权力人物主张私权利成立要件进行了分析。同时,作者从起诉行为的社会评价角度,说明了评论和评价都源自公权力的赋予者——社会公众。公权力组织和个人起诉主张自身的私权利这一行为并没有错,但其中需要注意起诉的条件。我国要成为法制国家,追求以法治国,必须成为一个宪政中国,尊重并保护公民的权利。  相似文献
