Design selection for strong orthogonal arrays

Strong orthogonal arrays (SOAs) were recently introduced and studied as a class of space‐filling designs for computer experiments. An important problem that has not been addressed in the literature is that of design selection for such arrays. In this article, we conduct a systematic investigation into this problem, and we focus on the most useful SOA(n,m,4,2 + )s and SOA(n,m,4,2)s. This article first addresses the problem of design selection for SOAs of strength 2+ by examining their three‐dimensional projections. Both theoretical and computational results are presented. When SOAs of strength 2+ do not exist, we formulate a general framework for the selection of SOAs of strength 2 by looking at their two‐dimensional projections. The approach is fruitful, as it is applicable when SOAs of strength 2+ do not exist and it gives rise to them when they do.

CIO自身技能、需求方领导力与数字化创新

现有研究强调数字化创新对企业的战略价值,但学术界对企业如何进行数字化创新的认识却较为有限.借鉴变革型领导理论,本文提出CIO需求方领导力正向影响企业数字化创新水平,同时,CIO结构权力可以增强CIO需求方领导力与企业数字化创新水平的正向关系.此外,从CIO自身技能方面识别出CIO需求方领导力的三个重要前因:战略IT知识、政治悟性以及网络能力.通过采集179份CIO-TMT的企业配对问卷数据进行实证分析,实证结果较好地支持了研究假设.本文提出的假设模型为企业发挥CIO在推进数字化创新中的主导作用提供了理论基础和实践启示.

少数民族山区发展的人口障碍

贫困山区大多是少数民族人口较多的地区 ,要解决贫困山区的人口问题 ,就有必要弄清少数民族山区的人口发展情况。笔者通过对黔南布依族苗族自治州人口发展的分析与研究 ,发现其人口的快速增长带来了一系列经济、生态、社会等问题。因此 ,要加快少数民族地区经济的发展步伐 ,就必须解决好人口问题。     

从"两论"起家到可持续发展——"两论"思想在大庆的实践

"两论"即毛泽东的《实践论》和《矛盾论》是对马克思主义发展观思想的拓展,是马克思主义中国化的具体体现;也是大庆社会全面进步,实现可持续发展的思想魂魄。"两论"思想蕴涵着马克思科学发展观的基本价值尺度,符合和谐社会思想的内在要求。通过"两论"思想在大庆发展实践中的主体化,作为各项工作的科学指导思想和行为准则,从"两论"起家,到大庆油田的成功开发建设,直至城市的现代化建设、人的全面发展和社会的全面进步,大庆所走过的辉煌历程,也是"两论"思想在大庆发展实践中充分践行的过程。"两论"不仅过去是,而且现在和未来都将是大庆发展实践的核心指导思想,是大庆可持续发展、社会全面进步的永恒的思想动力。

Working Time,Gender and Family: An East‐West European Comparison

This article provides a comparison of three West European countries with five Central East European countries in respect of working time and the integration of work and family life. The countries are the Netherlands, Sweden and the UK in West Europe and Bulgaria, the Czech Republic, Hungary, Romania and Slovenia in Central East Europe. As well as providing an East–West comparison, the article also takes into account the differing institutional and policy contexts in the selected countries and the different routes to flexibility. A further aim of the article is to extend our understanding of the culture and values which underpin the organization of family and work in each country. Whilst there is a clear East–West divide, all eight countries demonstrate diverse routes to flexibility and different mixes of social policies and gender cultures which have lead to considerable differences in the integration of work and family life.
