中美科幻小说的创作及研究进路考察——基于1990年代以来的科幻文学视域

科幻小说诞生于19世纪的欧洲,是科技与文学的一种融合.这种文学形式,以其特有的叙事方式,承载着人类探求未来世界、认知未来社会的精神寄望与诉求.作为世界的共有资源,中美两国的科幻小说在其创作及研究的进路中有着较大的距离差别.美国的科幻小说虽较晚于启蒙国英国,但作为科学技术大国、强国,其创作和研究的超越提速是较大的,出现了诸如罗伯特·海因莱因及《星船伞兵》、艾萨克·阿西莫夫及"基地"系列、"机器人"系列等等这样的科幻小说巨头及巨作,研究的深入跟进亦趋于世界前列;相对而言,中国科幻文坛虽曾有过20世纪50年代的辉煌,诞生了郑文光等名家,但中国现代科幻小说的创作及研究是滞后的.20世纪90年代以降,刘慈欣的《三体》三部曲、王晋康的《逃出母宇宙》等科幻大作的出现,使中国科幻小说的创作及研究吸引了世界的目光,其影响在改变着这一滞后的局面.世界科幻王国终于有了中国的声音.

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.     

NETWORKING CAPITALISM: Network Construction and Control Effects In Direct Selling

Drawing on a qualitative study of direct selling in Taiwan, this article examines the process of network construction and its control effects over distributors. I found that weak ties, rather than strong ties, constitute major networks for distributors to expand their business. In order to consolidate trust within weak ties, distributors develop two major strategies: personalizing sales and familiarizing sponsorship. They are engaged in a multilevel performance of emotional labor in facing the audience of customers and fellow distributors. Social networks not only function as a facilitator of economic exchange but also become a meáns of labor control that permeates both public and private lives of distributors.

德国1938年承认伪满洲国的原因

自1931年伪满洲国出笼后,德国政府采取并基本上维持了不承认政策。但是到了1938年2月,德国纳粹政府却背信弃义,不顾中国政府的反对,公开承认伪满。究其原因,主要在于:承认伪满是希特勒实施对外扩张战略的重要组成部分;纳粹德国已经完成了承认伪满的组织准备;陶德曼调停失败促使纳粹政府更加重日轻华;狄克逊对于纳粹党决策层有着重要的影响;承认伪满是德国与日本讨价还价的筹码等。
