胡春光  陈洪 《学前教育研究》2011,(9)

法国独特的幼小衔接教育制度是其初等教育走在世界前列的重要原因.在完备的法律规范下,其教育行政组织衔接、教学组织与课程规划衔接、师资聘用与培训衔接,有效地促进了学前教育与小学教育的一体化,使得法国的学前教育与小学教育既体现出合理的层次性,又具有良好的过渡性和连贯性.我国各级政府应加强对发展高质量学前教育的重要战略意义的认识,重视通过建立完备的法律制度保障幼小衔接工作的顺利开展,创新幼小衔接机制与途径,形成和完善能够真正尊重儿童个性发展特征与需要的幼小衔接教育制度.  相似文献

FARMER: A novel approach to file access correlation mining and evaluation reference model     

夏鹏  冯丹  王芳 《上海大学学报(英文版)》2011,15(6):574-588

File semantic has proven effective in optimizing large scale distributed file system. As a consequence of the elaborate and rich I/O interfaces between upper layer applications and file systems, file system can provide useful and insightful information about semantic. Hence, file semantic mining has become an increasingly important practice in both engineering and research community. Unfortunately, it is a challenge to exploit file semantic knowledge because a variety of factors could affect this information exploration process. Even worse, the challenges are exacerbated due to the intricate interdependency between these factors, and make it difficult to fully exploit the potentially important correlation among various semantic knowledges. This article proposes a file access correlation miming and evaluation reference (FARMER) model, where file is treated as a multivariate vector space, and each item within the vector corresponds a separate factor of the given file. The selection of factor depends on the application, examples of factors are file path, creator and executing program. If one particular factor occurs in both files, its value is non-zero. It is clear that the extent of inter-file relationships can be measured based on the likeness of their factor values in the semantic vectors. Benefit from this model, FARMER represents files as structured vectors of identifiers, and basic vector operations can be leveraged to quantify file correlation between two file vectors. FARMER model leverages linear regression model to estimate the strength of the relationship between file correlation and a set of influencing factors so that the “bad knowledge” can be filtered out. To demonstrate the ability of new FARMER model, FARMER is incorporated into a real large-scale object-based storage system as a case study to dynamically infer file correlations. In addition FARMER-enabled optimize service for metadata prefetching algorithm and object data layout algorithm is implemented. Experimental results show that is FARMER-enabled prefetching algorithm is shown to reduce the metadata operations latency by approximately 30%–40% when compared to a state-of-the-art metadata prefetching algorithm and a commonly used replacement policy.  相似文献

The function and accomplishment of each module in the system are described in general. In addition, according to the aforementioned scheme a prototype of TOC task management system is implemented, and the feasibility, rationality and completeness of the scheme are verified via running and testing the prototype.  相似文献   

Space- and time-efficient approach for virtual machine provisioning     

胡博林  雷州  许东  李建敦 《上海大学学报(英文版)》2011,15(5):451-455

As a new promising paradigm, cloud computing can make good use of economics of scale and elastically deliver almost any IT related services on demand. Nevertheless, one of the key problems remaining in cloud computing is related to virtual machine images, which require a great amount of space/time to reposit/provision, especially with diverse requests from thousands of users simultaneously. In this paper, by using the splitting and eliminating redundant data techniques, a space and time efficient approach for virtual machines is proposed. The experiments demonstrate that, compared with existing solutions, our approach can conserve more disk space and speed up the provisioning of virtual machines.  相似文献   

Searching high gray scale FPD scanning matrix based on PSO     

严利民  王念  田锋 《上海大学学报(英文版)》2011,15(3):207-211

With the increase of gray scale and flat panel display (FPD) size, subspace bitwise scanning strategy can be replaced traditional scanning method to cut down frame frequency. However, the direct searching strategy (DSS) becomes unfeasible to obtain corresponding high gray scale scanning matrix. Thus, particle swarm optimization (PSO) is introduced to accelerate searching for high gray scale weights scanning matrix (WSM) with its parallelism and global optimization feature. Finally a WSM of 256 gray scales is found out successfully with Matlab, which both gray linearity and scanning efficiency are satisfied.  相似文献

方红 《上海教育科研》2011,(3)

儿童哲学的诞生缘于20世纪60年代对话哲学与"批判性思维"运动的兴起.我国有近三十年的儿童哲学研究,相比于前二十年的研究,近十年的研究显得更为"理智",在引进、介绍、实验的同时,研究者开始对儿童哲学研究的方向和内容进行审视,寻找儿童哲学与中国教育改革的契合之路.  相似文献   

政府主导强力推进农村学前教育三年普及——河北省“三为主”学前教育发展模式的探索和启示     

洪秀敏  范明丽 《学前教育研究》2011,(11)

在强力推进农村学前教育三年普及过程中,河北省始终立足于学前教育的公益性,强化并落实政府主导责任,坚持“以政府和集体办园为主,以公办教师为主,以政府和集体投入为主”的“三为主”学前教育发展模式,使农村公办学前教育资源得到快速发展,实现了全省2/3以上的农村地区基本普及了学前三年教育.在此过程中,河北省对农村中小学布局调整后富余教育资源的合理有效利用经过实践检验,证明是切实可行的发展农村学前教育的有力措施,可以为我国其他地区,尤其是农村地区学前教育事业发展提供有益的启示和借鉴.  相似文献
