An Application of MCDM in Water Resources Problems

In this paper a practical application of MCDM in water resources problems is presented. Based on a real project for Qinhuangdao water resources management sponsored by Qinhuangdao Municipality, we construct a set of models for inflow forecast, reservoir operations, water supply and allocation, and flood routing for system optimal operation and flood management. A stochastic dynamic programming (DP) model with a fuzzy criterion is proposed for monthly reservoir operations. A series of goal programming (GP) models is built for water supply and allocation on different planning and operating levels. The DP–GP models fulfil the optimal operation tasks of a water resources management decision support system (WRMDSS) for Qinhuangdao water resources management.     

Stepwise contouring of efficient criterion vectors for large-scale MOLP

In this paper a new method of presenting the overall (focused) structure of the efficient criterion vectors (N) for large-scale MOLP is proposed. The proposed algorithm ASEOV (approximation of the set of efficient objective vectors) determines the representative subset of N and ensures full coverage of N , with corresponding coverage precision indicated. ASEOV works in objective space directly and eliminates unnecessary computational effort at the collapsing extreme points of X , which are transformed to non-extreme points in objective space. The Tchebycheff metric is employed to measure the coverage precision. ASEOV allows a decision maker (DM) to control the determination procedure by assessing the coverage allowance for each criterion. When the DM's preference is available, ASEOV can focus contouring on the subset of N which fits with the extracted preference. Combined with proper interactive methods, this focused contour over N can reduce the DM's burden, inconsistency or cognitive bias in assessing his preference from which to derive the final best-compromise solution. An illustrative example is presented.     

贫困问题:基于心理学的视角

贫困心理学,是在心理学视角下研究贫困问题的一种新研究取向,是心理学在贫困领域的最新运用。现阶段贫困心理学研究主要集中在主观幸福感、心理健康、行为决策等三个方面。贫困文化理论、稀缺理论、自我损耗论分别从贫困文化、稀缺心态以及意志力资源视角解释了贫困产生的心理机制。在摆脱贫困过程中需要打破贫困循环,未来贫困心理学研究需要进一步探讨贫困的产生机制、神经生理机制,贫困心理学的本土化研究以及心理学在扶贫工作中的应用等。     

含题组的测验等值

题组越来越多地出现在各类考试中, 采用标准的IRT模型对有题组的测验等值, 可能因忽略题组的局部相依性导致等值结果的失真。为解决此问题, 我们采用基于题组的2PTM模型及IRT特征曲线法等值, 以等值系数估计值的误差大小作为衡量标准, 以Wilcoxon符号秩检验为依据, 在几种不同情况下进行了大量的Monte Carlo模拟实验。实验结果表明, 考虑了局部相依性的题组模型2PTM绝大部分情况下都比2PLM等值的误差小且有显著性差异。另外, 用6种不同等值准则对2PTM等值并评价了不同条件下等值准则之间的优劣。     

小学教师课堂信息加工能力的研究

研究采用小学语文和数学教学录像为实验材料,以98名小学语文数学教师、其他学科教师和非教师为研究对象,运用反应时测量法探讨小学教师加工不同类型课堂信息的速度和辨别能力。结果表明:有学科教学经验的教师(语文和数学教师)在重视学科教学内容的同时,也重视课堂教学活动的组织和课堂气氛的调节;学科知识、学科教学经验和课堂教学经验对教师的课堂信息加工能力和教学专长发展有显著的影响;研究结论对提高教师课堂教学能力、教学专长以及教师培训提供了有力的实验证据。     

成人依恋、情绪调节与主观幸福感:重新评价和表达抑制的中介作用

通过对1163名大学生被试进行成人依恋关系、情绪调节策略的使用以及主观幸福感的测查,该研究从情绪调节这一新的视角,深入探讨了成人依恋对主观幸福感产生影响的可能机制。结果发现:重新评价策略的使用在依恋安全对主观幸福感影响中具有重要的中介作用;依恋回避直接影响个体的主观幸福感;表达抑制对主观幸福感影响不显著。这些结果表明重新评价策略的使用是成人依恋关系影响个体主观幸福感的一个重要途径。     

Delimiting the concept of research: an ethical perspective

It is important to be able to offer an account of which activities count as scientific research, given our current interest in promoting research as a means to benefit humankind and in ethically regulating it. We attempt to offer such an account, arguing that we need to consider both the procedural and functional dimensions of an activity before we can establish whether it is a genuine instance of scientific research. By placing research in a broader schema of activities, the similarities and differences between research activities and other activities become visible. It is also easier to show why some activities that do not count as research can sometimes be confused with research and why some other activities can be regarded only partially as research. Although the concept of research is important to delimit a class of activities which we might be morally obliged to promote, we observe that the class of activities which are regarded as subject to ethical regulation is not exhausted by research activities. We argue that, whether they be research or not, all the activities that are likely to affect the rights and interests of the individuals involved and impact on the rights and interests of other individuals raise ethical issues and might be in need of ethical regulation.     

汉语主、宾关系从句加工难度及其核心名词生命性效应

采用眼动追踪实验技术,考查了核心名词生命性取向对汉语主、宾关系从句加工难度调节效应。结果显示:(1)核心名词生命性格局对汉语主、宾关系从句的加工难度有着显著调节作用,具体表现为:当主、从句中的核心名词为"生命性-非生命性"格局时,在主句核心名词、核心动词位置,宾语关系从句加工较为容易;当主、从句中的核心名词为"非生命性-生命性"格局时,在上述位置,两种关系从句加工难度差异不显著;(2)汉语主、宾关系从句加工中核心名词生命性效应主要发生在语义信息提取、论元关系建构阶段,体现出汉语语言的特异性。上述结果支持了题元切适性理论。     

From Assessment to Design: What Is Really Needed in Technology Accompaniment to Achieve Subject Constitution?

Based on the argument that technologies mediate human experience and praxis, the idea of technology accompaniment has been suggested as an approach to developing human-tech relations. In light of this idea, this paper argues, firstly, that when technologies inevitably have moral relevance in influencing human perceptions and actions, the constitution of a moral subject has much to do with shaping technological mediation deliberately and creatively. While there is not always a direct connection between what humans know and what humans do, technological mediation can help to strengthen people’s motivation to do the right thing. Subsequently, we examine two approaches that have often been suggested for realizing subject-constitution-with-technology: one is Technology Assessment, and the other is Mediation Design. Although the former can equip people with knowledge about technological mediation, it is relatively weak when it comes to directly producing moral behavior. In contrast, the latter not only exerts a more direct impact on user behavior but may also improve people’s moral knowledge. Nonetheless, both approaches face the general challenge of moral education. As moral knowledge does not guarantee moral behavior, knowing facts and theories about technological mediation may not lead to subject constitution as a result of the development of the human-tech relationship. To overcome this difficulty, an extension of the latter approach is proposed. The design of meta-mediation has great potential to shift users’ attention to the aforementioned mediating effect of technology-in-use and, thereby, users’ subject constitution can be enabled.
