论课堂教学的动态化

课堂教学是一门艺术,艺术是一种创造性的劳动,课堂教学的艺术体现在教学活动的动态化流程中并为教学效果服务。通过对课堂教学的动态化进行理论界定,通过对教学要素的具体分析,可以看到引入课堂教学动态化的必要性。同时,进一步探讨了如何实现课堂教学的动态化。     

关于恩格斯社会发展的合力思想及其启示

恩格斯的合力思想严格说来有广义和狭义之分,狭义的合力指的是人们的“意志合力”,广义的合力是指包含“意志合力”在内的“总合力”.恩格斯认为,每一个人的意志因素在社会发展中不是孤立地、单独地直接对社会发生作用,而是与其他意志相互作用、相互渗透,从而作为一个不依赖于人的意志为转移的总体的“意志合力”对社会发生综合的影响;包含“意志合力”在内的“总合力”的情况也类似,经济因素、政治因素和文化因素作为社会发展中的动力因素,也不是孤立地、单独地对社会发展发挥作用,而是融合为一个“总合力”从而推动社会发展.精神因素在社会发展中的作用不是决定性的,但它在社会发展中的作用呈现出递增的趋势.经济因素在社会发展中的作用是决定性的,但这是在“     

Development of an RFID‐based Traceability System: Experiences and Lessons Learned from an Aircraft Engineering Company

This paper presents a case study of the research and development of an RFID‐based traceability system in an aircraft engineering company in Hong Kong. We report the system design and implementation, and discuss our experiences and lessons learned. The aim of the RFID system is to effectively support the tracking and tracing of aeroplane repairable items in the company. The study reveals eight critical success factors for the successful implementation of RFID systems, namely, create strong internal and external motivation for improvement, stir up desire to keep abreast of the latest technology for global competitiveness, strive for cross organizational implementation, avoid major process changes/limit process changes, start with a small RFID project scope, facilitate equipment vendor's investment, use cost‐effectiveness reusable tags, and transfer RFID skills and knowledge from university to industry. We also summarize 13 lessons learned, including three lessons concerning RFID implementation at strategic level, six lessons at management level, and four lessons at operational level resulting from carrying out this project. Given the contextual details of the study, the lessons learned can help other firms to better anticipate the hurdles they will experience, and make them aware of the possible ways to cope with such difficulties before embarking on the journey of RFID implementation.     

Packing <Emphasis Type="Bold">[1, Δ]</Emphasis>-factors in graphs of small degree

Given an undirected, connected graph G with maximum degree Δ, we introduce the concept of a [1, Δ]-factor k-packing in G, defined as a set of k edge-disjoint subgraphs of G such that every vertex of G has an incident edge in at least one subgraph. The problem of deciding whether a graph admits a [1,Δ]-factor k-packing is shown to be solvable in linear time for k = 2, but NP-complete for all k≥ 3. For k = 2, the optimisation problem of minimising the total number of edges of the subgraphs of the packing is NP-hard even when restricted to subcubic planar graphs, but can in general be approximated within a factor of by reduction to the Maximum 2-Edge-Colorable Subgraph problem. Finally, we discuss implications of the obtained results for the problem of fault-tolerant guarding of a grid, which provides the main motivation for research.     

外交决策过程中的现代科学因素

现代科学的发展扩大了外交信息的接收范围,提高了反馈的速率,系统的决策理论成为指导外交决策的方法论,外交咨询机构科学化、专业化的工作提高了外交决策的效率。外交决策实现了从经验决策到科学决策的转变。外交决策过程中的现代科学因素愈发凸现。     

社会主义因素在资本主义内部的生成与扩张--马克思恩格斯思想的历史考察及其现实意义

在马克思恩格斯看来,资产阶级极大地发展了社会生产力,为社会主义创造了物质和精神条件;合作经济是向共产主义过渡的中间环节;股份制是资本主义经济转化为社会主义经济的过渡形式等,标志着社会主义新社会的因素已经在资本主义内部生成与扩张.理性地审视当代社会主义与资本主义发展的现实,深入挖掘马克思恩格斯思想的丰富内涵,对于建设中国特色社会主义具有重要的现实意义.     

非劳动收入与按生产要素分配

非劳动收入是我国当前收入分配制度中的重要内容。由于人们对非劳动收入至今仍存在各种不同的看法,甚至把它等同于剥削收入,因此,有必要对非劳动收入作进一步分析,对其性质作出科学界定。文章通过分析劳动和生产要素在创造价值中的作用及决定分配的因素,提出了按生产要素分配不是剥削的观点。

Determining Six Sigma success factors in Turkey by using structural equation modeling

Since it includes strong statistical and executive techniques, Six Sigma (SS) succeeded in many countries and different sectors. Especially successful SS applications of many international companies have increased the interest of other companies. As a result of this, the number of implemented SS projects in various countries has increased. Although successful SS projects are often in mind, the number of failed projects because of various reasons is not as low as to be ignored. As well as there are many factors that affect the success level of SS projects, and these factors vary according to countries. In this study, a survey was applied to 117 people who have 1 of SS belts in order to determine success levels of the SS projects in Turkey. By using explanatory factor analysis and structural equation modeling, critical success factors were determined. According to the results, project selection and its scope, quality culture and defining and measuring of metrics were determined as the top factors that are affecting success levels of SS projects applied in Turkey. The results of the study were also compared with the results of similar projects implemented in other countries.     

Heteroscedasticity Robust Panel Unit Root Tests

This article proposes new unit root tests for panels where the errors may be not only serial and/or cross-correlated, but also unconditionally heteroscedastic. Despite their generality, the test statistics are shown to be very simple to implement, requiring only minimal corrections and still the limiting distributions under the null hypothesis are completely free from nuisance parameters. Monte Carlo evidence is also provided to suggest that the new tests perform well in small samples, also when compared to some of the existing tests. Supplementary materials for this article are available online.
