《屈原列传》指瑕

屈原是我国文学史上第一个伟大诗人,他用自己的生命熔铸的不朽诗篇,昭示了光明的理想。为了丰富屈原的伟大形象,这里用翔实的史料,明证屈原遭谗被疏的复杂性,希望当今史学家能根据历史的轨辙,增删《屈原列传》,以求证历史的本源。     

Back to the future on gender and anti‐school boys: a response to Jeffrey Smith

This article examines recent claims by Jeffrey Smith that: (1) ‘hegemonic masculinity’ is an expression of working class counter‐school culture; (2) some teachers are ‘cultural accomplices’ in constructing ‘hegemonic masculinities’ of anti‐school working class boys, thereby contributing to their underachievement; and (3) these ‘cultural accomplices’ are an emerging response to recent moral panics and neo‐liberal managerialism concerned with ‘failing boys’ at school. It is suggested that ‘hegemonic masculinity’ is not necessarily associated with anti‐school values in working class culture. Many working class boys might subscribe to ‘hegemonic masculinity’ without rejecting learning. Contrary to Smith’s emphasis on how working class culture generates anti‐school ‘hegemonic masculinity’, there is the possibility that ‘hegemonic masculinity’ is fused with anti‐school values produced by organisational differentiation. The continuing commonalities between working class anti‐school boys and the ‘gender regime’ of some secondary schools for over 20 years implies something more enduring at work than recent moral panics.     

提升贵州旅游价值的差异化思考

贵州山清水秀,原始生态景观极为丰富,人文文化独特美丽。而长期以来这些自然资源都没有得到充分的认识、开发和利用,从现实的资源状况出发,结合实际从战略管理和营销管理的角度对资源动态价值差异化提出人力资源管理差异化、服务差异化、升华无形资产差异化和TQM差异化等构思,为提升贵州旅游的价值探讨一个发展方向。     

网上直销渠道的动态投资对供应商及零售商策略选择的影响

为研究网上直销商与传统供应商之间的竞争,建立可分析供应商对网上直销动态投资策略对供应链影响的供应商、网上直销渠道和传统零售商竞争的微分博弈模型.经过系统动力学模拟,得出供应商和零售商的最优策略.通过不开设和开设网上直销渠道2种情况下供应商利润总和的对比表明:开设网上直销渠道可以改变供应商和零售商的竞争模式,加强零售市场的差异化竞争程度,进而增加供应商的利润;而生产成本和需求弹性较低的商品更适合网上直销.

差异化协同发展成为后疫情时期东北冰雪旅游产业高质量发展的优选之路。运用文献资料、逻辑分析等方法,在经典的差异化和协同理论阐释基础上,解析东北冰雪旅游产业差异化协同发展的逻辑:东北要素禀赋的比较优势推动冰雪旅游产业差异化发展、东北条件基础的合作优势推动冰雪旅游产业协同发展、差异化与协同互动成为东北冰雪旅游高质量发展内生动力等;东北冰雪旅游产业存在的问题:差异化不明显导致东北冰雪旅游产业比较优势难以发挥、协同不充分导致东北冰雪旅游产业合作优势难以彰显、差异化与协同互动不足导致东北冰雪旅游产业发展动力难以生成等。提出发展路径:通过打造差异化发挥东北冰雪旅游产业发展的比较优势,通过建构协同模式彰显东北冰雪旅游产业发展的合作优势,通过推动差异化与协同互动激活东北冰雪旅游产业发展的内生动力。     

Two-dimensional optical spatial differentiation and high-contrast imaging

Optical analog signal processing technology has been widely studied and applied in a variety of science and engineering fields, with the advantages of overcoming the low-speed and high-power consumption associated with its digital counterparts. Much attention has been given to emerging metasurface technology in the field of optical imaging and processing systems. Here, we demonstrate, for the first time, broadband two-dimensional spatial differentiation and high-contrast edge imaging based on a dielectric metasurface across the whole visible spectrum. This edge detection method works for both intensity and phase objects simply by inserting the metasurface into a commercial optical microscope. This highly efficient metasurface performing a basic optical differentiation operation opens up new opportunities in applications of fast, compactible and power-efficient ultrathin devices for data processing and biological imaging.
