民办幼儿园教师专业素养培训方式实验研究

随着现代教育的发展，提升幼儿园教师专业素养已成为促进学前教育发展的必然要求。以探究民办幼儿园教师专业素养为视角，提出通过干预行为提升教师专业素养水平的构想。实验随机选取成都市某民办幼儿园的20名教师为实验组，再选取与其办园环境、办园背景相似的另一所民办幼儿园的20名教师为对照组，对实验园教师的专业理念与师德、专业知识、专业能力3个维度进行干预。实验结果表明：与对照园相比，实验园教师的专业能力提升显著；与实验园实验前后相比，教师在专业知识、专业能力维度及专业素养总体水平方面均有提升。对教师培训的具体建议为：（1）单一与混合相结合的培训方式对提升民办幼儿园教师专业素养总体水平有现实意义；（2）民办幼儿园教师专业知识的提升需理论培训与自主学习相结合；（3）专家"现场诊断-指导式"培训方式对提升民办幼儿园教师专业能力有显著作用。综上，建议民办幼儿园在了解本园教师专业素养水平的基础上，针对教师专业素养的不同方面，分别采取不同的有效培训方式。

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.

茶酒争胜与文化张力:以《茶酒论》为中心的考察

茶与酒作为日常生活的基本形式，相互之间各有所长而内在紧张。敦煌写本《茶酒论》生动刻画了茶酒之辩的核心问题，从自然属性、社会功用、健康养生到道德教化，茶酒之间历经了茶酒并行、茶酒争胜、褒茶贬酒的趋向，最后以水的出场调和而告终。研究茶酒之辩，既要汲取与超越以茶喻佛、以酒喻道、以水喻儒、三教合流的解释，更要借鉴茶酒争胜所展示的文化张力，推动优秀传统文化的发展和创新。     

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.     

精神脱贫:内涵阐释与路径探索

贫困是一个多维概念,物质脱贫之后,还有精神脱贫问题.所谓精神脱贫,是指个体或者群体的精神水平和观念素质不落后于社会物质生产方式和社会整体精神与观念素质平均水平的生存状态.精神脱贫的内涵具有动态变化性,新发展阶段精神脱贫主要由互相关联的四方面构成:主体意识是基础,积极进取的人生态度、主动参与精神是核心,科学的思维方式是表现.四方面密不可分,相辅相成,共同构成新发展阶段精神脱贫的丰富内涵.新发展阶段推进精神脱贫:一是要精准识别,摸清精神扶贫对象,这是必要前提;二是加强教育,培养主体意识,这是重要基础;三是积极开展文化活动,以文化人,这是关键措施;四是巧用典型,提振精气神,这是有益补充.     

The disembedded digital economy: Social protection for new economy employment in China

This research focuses upon employment in the new economy, exploring labour protection and social protection in the digital age in China. Through an empirical survey conducted in three Chinese cities, social insurance and the labour rights of employees in the digital economic sector, such as gig employment, e-commerce, and various other forms of online employment, have been examined in-depth. This study reveals new regulatory loopholes in the digital labour market, which have substantially eroded the basis of social policy arrangements in China, “softening” participation in social insurance branches and compliance with labour regulations remarkably. Drawing upon the theoretical concepts of Polanyi on embeddedness and disembeddedness, we argue that the digital employment sector in China has been increasingly disembedded from social institutions and social control. The new configuration in the digital field of social policy requires novel conceptual models and institutional settings to cope with increasing social risks in virtual spaces.
