困境与出路——甘孜藏区“9＋3”教育模式的内地实践     

巴呷 《康定民族师范高等专科学校学报》2010,19(3):88-90

藏区＂9＋3＂免费教育工程是指藏区少数民族学生在接受过9年制义务教育的基础上,再把一部分学生送到内地相关学校免费进行3年的中等职业教育。这是省委、省政府为提高藏区人民受教育水平而进行的一项民生工程,自实施以来,取得了一定的成绩,但同时也存在很多问题,需要在实践中不断探索改进。  相似文献

Information encountering and management in information literacy instruction of undergraduate,students     

Kristine N. Stewart  Josipa Basic 《International Journal of Information Management》2014

The nature of the information-rich environment of the 21st century has affected the ways in which students’ access information. Students no longer have to seek information; they acquire it passively through their everyday use of the Internet. This paper presents findings of a study involving the information encountering experiences of undergraduate students and the potential role of personal information collection, management, and retrieval in information literacy instruction. Undergraduate students enrolled in an information literacy course were surveyed regarding their experiences online with information encountering and personal information management. Survey questions were adopted from the information encountering scale developed by Wise & Erdelez (2012) and consisted of twelve questions focused on the noticing, stopping, examining, and capturing steps of the Information encountering model (Erdelez, 2004). The study indicates that the vast majority of the undergraduate students responding to the survey were frequently encountering unexpected information while online, but were not capturing this information for future use using built-in, web-based tools. While information literacy courses teach students to identify, seek, analyze, and use needed information, they do not prepare them to manage and retrieve unexpected information encountered while using the Internet.  相似文献   

微信群内部的会话网络结构及关键节点测度研究     

巴志超  李纲  王晓  李显鑫 《图书情报工作》2017,61(20):111-119

[目的/意义]微信群内部存在着复杂的会话网络结构,探究微信群内部网络结构特征、角色类型以及相互关系对认识微信用户信息行为与传播模式具有重要意义。[方法/过程]以真实微信群中的对话样本作为研究对象,以成员之间的@关系及交流强度作为边权重构建行为网络,采用社会网络分析和内容分析方法对微信群中会话网络结构的统计特征、核心成员识别、信息交流行为等进行分析,并设计基于数量、黏度和位置的微信群用户影响力计算模型。[结果/结论]微信群中成员发言数近似服从分段幂律分布,其幂律指数与成员活跃度成正比关系;仅依赖发言数和发言分布时间无法反映成员在网络中的地位和影响力,其与中心性、个体网络特征等指标存在不一致;微信群内的信息交流更多是一种"有限度"和"碎片化"的交流,而群间的信息流动则表现为逐级过滤、舆情风险逐级削减的趋势。  相似文献

The position-based impedance control combined with compliance-eliminated and feedforward compensation for HDU of legged robot     

Kaixian Ba  Bin Yu  Qixin Zhu  Zhengjie Gao  Guoliang Ma  Zhengguo Jin  Xiangdong Kong 《Journal of The Franklin Institute》2019,356(16):9232-9253

In this paper, the hydraulic drive unit (HDU) driving the joint motion of the legged robot is the research object. Through the experiment on HDU, it is observed that the control accuracy of the traditional position-based impedance control is not high enough. The further analysis researches the serial-parallel composition on dynamic compliances from both position control inner and impedance outer loop. Then, the two reasons affecting control accuracy are found out. Therefore, aimed at the first reason, a compliance-eliminated controller with multiple serial branches is designed. Aimed at the second reason, a feedforward compensation controller is designed. Finally, the dynamic compliance composition is rearranged. The results of experiments conducted indicate that the proposed method significantly improves the control accuracy compared to that of traditional position-based impedance control.  相似文献

Immobilization of functional nano-objects in living engineered bacterial biofilms for catalytic applications     

Xinyu Wang  Jiahua Pu  Yi Liu  Fang Ba  Mengkui Cui  Ke Li  Yu Xie  Yan Nie  Qixi Mi  Tao Li  Lingli Liu  Manzhou Zhu  Chao Zhong 《国家科学评论(英文版)》2019,6(5):929

Nanoscale objects feature very large surface-area-to-volume ratios and are now understood as powerful tools for catalysis, but their nature as nanomaterials brings challenges including toxicity and nanomaterial pollution. Immobilization is considered a feasible strategy for addressing these limitations. Here, as a proof-of-concept for the immobilization of nanoscale catalysts in the extracellular matrix of bacterial biofilms, we genetically engineered amyloid monomers of the Escherichia coli curli nanofiber system that are secreted and can self-assemble and anchor nano-objects in a spatially precise manner. We demonstrated three scalable, tunable and reusable catalysis systems: biofilm-anchored gold nanoparticles to reduce nitro aromatic compounds such as the pollutant p-nitrophenol, biofilm-anchored hybrid Cd_0.9Zn_0.1S quantum dots and gold nanoparticles to degrade organic dyes and biofilm-anchored CdSeS@ZnS quantum dots in a semi-artificial photosynthesis system for hydrogen production. Our work demonstrates how the ability of biofilms to grow in scalable and complex spatial arrangements can be exploited for catalytic applications and clearly illustrates the design utility of segregating high-energy nano-objects from injury-prone cellular components by engineering anchoring points in an extracellular matrix.  相似文献
