贴体网格生成技术中正交性和空间疏密控制研究

在综合阐述网格生成技术对流场数值计算重要性的基础上,提出了一种非周期性叶栅流场网格的数值生成方法。该方法对任意曲线（面）边界生成正交性思想的网格具有普适性,且可以对整个区域网格的正交性进行有效的控制。此外,本文还对网格正交性和疏密分布之间的关系进行了探讨,给出了影响网格正交性的因素和改进方法。     

Pseudo-Youden designs balanced for intersection

If the row-column intersections of a row-column design A form a balanced incomplete block design, then A is said to be balanced for intersection. This property was originally defined for triple arrays by McSorley et al. (2005a), Section 8, where an example was presented and questions of existence were raised and discussed. We give sufficient conditions for the class of balanced grids in order to be balanced for intersection, and prove that a family of binary pseudo-Youden designs has this property.

When near means related: evidence from three web survey experiments on inter-item correlations in grid questions

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design on inter-item correlations of follow-up questions. We found that the inter-item correlations in grid designs were higher for both the set of five and seven items than for questions in a single-item design. Additionally, the inter-item correlations of the set of follow-up questions were higher if the preceding set of questions was presented in a grid. According to the findings of the present research, respondents seem to apply the interpretative near means related heuristic when answering grid questions, and also when answering follow-up questions preceeded by grid questions.     

STIRring the grid: engaging energy systems design and planning in the context of urban sociotechnical imaginaries

Since the first electrification systems were established in the United States between 1910 and 1930, energy systems governance at the municipal level has included competing visions for how engineering design and energy policy-making should foster particular social outcomes. Using Phoenix as a representative metropolitan area, and the cases of distributed generation and in-home power management devices as examples, this paper explores how the norms and values embedded in energy systems design and planning shape how residents experience change in the energy grid. Through these case studies, the authors argue that such “sociotechnical imaginaries” – collectively formed visions of social life related to science and technology development – are a crucial, yet overlooked, pathway for social science to engage in fostering socially reflexive mechanisms in energy development. To conclude, the authors outline a research program for applying the established methodology of socio-technical integration research (STIR) in order to develop socially reflexive capacities in municipal energy producing, regulating, and planning institutions. Such a program has the ability to produce a deeper intellectual understanding of how energy development occurs, and in doing so generate new pathways for fostering cultural and material changes in the structure of contemporary energy systems.     

深化我国电网企业改革的策略选择

如何进一步推进电力改革的深化,促进具有自然垄断企业特征的电网企业实现组织转型,是当前深化电力改革的紧迫问题。本文针对当前电网企业输配售一体化的格局,提出积极推进售电侧市场放开,应是当前电网企业深化改革的重要选择。     

县域网格化管理模式的检视与反思——基于宜章县网格化管理的实证分析

在现代城市未来发展方向和治理现代化的语境下,网格化管理模式的借鉴与复制在基层的应用中产生了异化现象。县域网格化管理的推广和应用应遵循以人为本的目标,以社会自治为基础,以信息化为支撑,以法治为保障的逻辑理路展开。     

电网项目综合后评估模型的建立研究

电力行业是关系国计民生的基础产业,对促进国民经济的发展和社会进步起重要作用,因此,电网项目综合后评估尤为重要.在基于前期研究所建立的基于知识管理的电网项目后评估指标体系的基础上.利用AHP分析方法分析计算得出各项指标的权重;在基于各专家所得到的各指标的权重建立各指标权重范围,结合利用AHP和DEA方法,根据CCR-AR模型,最终建立起电网项目综合后评估模型.     

需求-供给视角下北京社区养老研究--基于朝阳区12个社区调查

随着人口结构的变迁,中国养老模式逐渐由以家庭为核的橄榄型结构向以社区养老为核的橄榄型结构变迁。社区养老将家庭范畴由传统家庭扩展到社区大家庭,将家庭养老的情感依赖与机构养老的专业服务融入社区养老平台。 S街道老年人需求分布呈现出：基本生理需求＞精神需求＞社会服务需求的序列。社区养老供需失衡的根源在于政府供给错位、市场购买的实践梗阻、社会团体的供给失灵。在信息时代,“数字化社区网格养老”利用成熟的城市网格管理系统,以社区网格为单位,在政府统筹下精准投入多元养老资源,借助于互联网＋社区＋养老的信息化方式,实现养老服务的精细化管理与无缝隙服务。     

Relational schemas as sources of evaluation and misevaluation of leader–member exchanges: Some initial evidence

We investigated whether dyad members' relational schemas, a cognitive representation of exchange experiences, would affect how leaders and members evaluate and misevaluate the quality of their exchange relationships. Based on data derived from repertory grid technique and two waves of survey data, we found that leaders and members tended to form different relational schemas of their partners. While leaders developed LMX schemas focusing on work-related issues, members' schemas focused more on interpersonal concerns. These findings confirmed that the different schemas employed by each party affect how they stored, retrieved and (mis)evaluated their LMX experiences with each other. Implications for theory and practice, limitations of this study, and future research directions are discussed.
