服务机器人多通道人机交互感知反馈工作机制及关键技术

With the increasing of the elderly population and the growing health care cost, the role of service robots in aiding the disabled and the elderly is becoming important.Many researchers in the world have paid much attention to healthcare robots and rehabilitation robots.     

反馈网络的直接传输作用分析

通过对一具体反馈放大电路的分析,把该电路的解析分析结果分解为反馈网络直接传输作用和反向传输作用两个部分,并据此对该放大电路分析结果的两个疑问作出了解释.     

城市农民工的住房

中国农民工长期工作在城市,从事各种职业,技术水平也高低不同。但是,他们的居住条件却惊人类似,人均居住面积不足4平方米,住房设施简陋、环境差,同质性强,居住模式以集体居住为主,居住伙伴多为同伴民工,家庭形式居住的农民工只占23.3%。尽管居住方面处于绝对剥夺状态,农民工对自己的居住条件仍然表现出中度的满意水平。其中的原因主要是他们选择的参照群体为同类民工,而且认同当前的市场分配逻辑。但是当结果公平分配原则被他们更多认知的时候,他们的相对剥夺感会极大提升,由此产生的后果会对和谐社会的构建产生巨大挑战。     

近十年国际高等教育评估研究的现状、热点及趋势

《高等教育评估与评价》(Assessment&Evaluation in Higher Education)作为唯一被SSCI收录的高等教育评估期刊,具有很大的学术影响力。以该期刊近十年来的载文为研究对象,运用CiteSpace文献计量软件分析国际高等教育评估的高影响力作者群体、研究热点、知识基础和前沿领域。研究结果表明:我国高等教育评估研究者的国际影响力逐步扩大;强调学生在评估中的参与度、关注反馈在评估中的地位以及重视教与学微观层面的评估为国际高等教育评估的三大研究热点;学生评教以及评估设计将是未来一段时间国际高等教育评估的前沿领域。     

反馈原理在体育教学训练中的应用

从生理学反馈信息这一理论角度出发,将人为性的建设性反馈在教学训练中加以运用,使整个训练得到科学调控,减少随机性,这样才能使整个教学训练的效果得以提高.     

Training preservice teachers to use evidence-based practices: Effects of coaching with performance feedback on teacher and child outcomes

Three-term contingency trials (TCTs) involve planned/naturally occurring antecedents, child's demonstration of target behaviors, and planned/naturally occurring consequences. Positive relationships between teachers' frequent use of TCTs and children's learning were noted in literature. This study aimed to investigate impact of an intervention package including training and coaching with performance feedback on experienced and novice special education preservice teachers' use of TCTs and relationship between teachers' implementation and child outcomes through two single-case experiments using multiple baseline across participants design. Three special education preservice teachers and three children with disabilities participated in each study. Results indicated intervention package was effective in increasing preservice teachers' use of TCTs. Preservice teachers generalized their use and sustained it during maintenance sessions conducted after intervention ended. Furthermore, as frequency and accuracy of preservice teachers' implementation increased, percentage of children's correct responses in relation to target skills improved. Implications for future practice and research are discussed.     

农民意见表达制度化的思考

目前，我国农民的意见表达还存在着许多问题，如地域上的差异，形式单调，内容狭窄、集中，效力微弱等，给社会的发展和政治稳定带来了不利影响。农民意见表达需要制度化、规范化。表达渠道畅通是农民意见表达制度化的重要保障，减轻负担、增加收入是经济前提，社会主流政治文化的宣传是文化前提，决策的科学民主化是政治前提，农村民主制度的完善是现实途径。农民意见表达的制度化对构建和谐社会有着重要的现实意义。     

A review of ontology based query expansion

This paper examines the meaning of context in relation to ontology based query expansion and contains a review of query expansion approaches. The various query expansion approaches include relevance feedback, corpus dependent knowledge models and corpus independent knowledge models. Case studies detailing query expansion using domain-specific and domain-independent ontologies are also included. The penultimate section attempts to synthesise the information obtained from the review and provide success factors in using an ontology for query expansion. Finally the area of further research in applying context from an ontology to query expansion within a newswire domain is described.     

融入与“断连”:老年群体ICT使用的学术话语框架分析

本文通过对国内有关老年群体信息传播技术(ICT)使用的学术话语展开框架分析,阐释了框架的建构及其背后的预设。分析发现,既有研究的话语框架倾向于将老年群体的"断连"(disconnect)行为问题化,强调数字融入的积极影响和断开连接的负面影响,并将问题归因为老年群体对技术的恐惧和新媒体素养的匮乏,呼吁通过文化反哺等社会干预策略让老年群体"跑步"进入数字化。本文提出将"断连"视为一种文化现象加以考察,探寻其中所编织的意义之网,丰富老年群体的信息传播技术使用的面向。此外,置身于无处不在的"连接文化"之中,应当营造一个对老年群体更为友好的基础设施环境与语言环境,在公共生活中提供多种选择的可能。
