Understanding divergent domestication traits from the whole-genome sequencing of swamp- and river-buffalo populations

Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals (132 swamp buffaloes and 98 river buffaloes) sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production.     

我国开放存取政策探讨

开放存取运动发展迅速,需要有相应的政策加以引导和促进.目前,我国制订开放存取政策不仅是必要的,也是可行的.国外的开放存取政策,尤其是美国的MH公共获取政策,对我国制定自己的开放存取政策具有很好的借鉴作用.我国政府应该尽早制定出符合我国国情的开放存取政策.参考文献5.     

Replication,pathogenicity, and transmission of SARS-CoV-2 in minks

Minks are raised in many countries and have transmitted severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans. However, the biologic properties of SARS-CoV-2 in minks are largely unknown. Here, we investigated and found that SARS-CoV-2 replicates efficiently in both the upper and lower respiratory tracts, and transmits efficiently in minks via respiratory droplets; pulmonary lesions caused by SARS-CoV-2 in minks are similar to those seen in humans with COVID-19. We further found that a spike protein-based subunit vaccine largely prevented SARS-CoV-2 replication and lung damage caused by SARS-CoV-2 infection in minks. Our study indicates that minks are a useful animal model for evaluating the efficacy of drugs or vaccines against COVID-19 and that vaccination is a potential strategy to prevent minks from transmitting SARS-CoV-2.     

Xu Beihong and the New China: thoughts centered on the painting At the World Peace Congress

This essay analyses a politically tinged painting by Xu Beihong (1895–1953), a representative modern Chinese painter. He composed the work in 1949, just before the founding of the People’s Republic of China, or the New China. In this article’s discussion of the perplexing work, the author attempts to unveil Xu’s understanding of revolution and of the relationship between art and politics, in relation to his difficulties in exploring and practicing art in the early Republic period (1912–1949). Based on this, the author discusses the painter’s mindset in the social and political context of the New China. She also tries to reveal that Xu’s art practices were restrained by the realities he was in – a crucial point to understanding his achievements and predicaments. As an artist who resisted the western modernism in the course of modernization, and who idealistically pursued the highest good and beauty through “realist” approaches and historical expressions, Xu’s predicaments interestingly reflect the complicated relationship between art and revolution in China’s road to modernization, and provide a foundation for further explorations into the core issues and the particularity of modern Chinese paintings.

作为媒介的博物馆及其在中国的专业化发展方向

博物馆是为数不多的、能与受众直接沟通的媒介,虽然小众,但传播内容真实形象、纵观古今,传播方式倡导多感官认知和身体交互,由此在学习、社交和崇拜三方面呈现出不可替代的媒介优势。但目前我国博物馆的这些潜在优势尚未完全释放,究其根源在于专业化程度不高。为此,需要更新认识论以弥补理论和实践的断裂;在整体论视阈下通过关联需求和重组业务提升专业化水平;基于观众立场廓清博物馆学科并提出中国方案。促使博物馆经由专业化发挥其独特的媒介潜能,从根本上帮助破解国人全面发展的难题。     

"数学物理方程"教学上的"三突出"

文章研究和探讨在教学时数减少的条件下,怎样搞好“数学物理方程”及其相关课程的教学工作。结论是在课程讲授中要在三个方面突出教学重点:即讲授理论,要突出阐述基本的数学思想;讲授概念,要突出讲授有关的物理背景;讲授解法,要突出训练主要的求解方法。     

中国企业跨国并购提升了其研发能力吗?——来自“一带一路”沿线国家的证据

基于2001-2014年中国企业对“一带一路”沿线国家海外并购数据，利用PSM方法研究了跨国并购对母公司研发创新的影响。结果表明：总体上来看，中国企业对“一带一路”国家的跨国并购显著提升了其研发水平；相比较于劳动密集型产业，资本密集型产业对资本要素和研发创新技术具有较强的敏感性，跨国并购对其研发创新的影响更明显；相比较于东部地区，由于中西部地区企业创新能力较低且多以要素密集型为主，跨国并购对中西部地区跨国企业研发创新的影响较弱。此外，在考虑目标企业所在国家（地区）的地理分布和创新能力因素时发现，跨国并购对母公司研发创新的提升效用随着目标企业所在国家创新能力的减弱而下降。最后，本文实证研究的基础上提出了相应的对策建议。     

环境约束对外商直接投资企业研发创新的影响-基于PSM方法的研究

在中国产业结构优化升级的过程中,外商直接投资对产业研发创新的重要性日益凸显,与此同时,为应对日益严峻的环境污染问题所制定的环境保护政策是否会对外资企业研发创新造成影响。文本利用2004~2007年企业层面微观数据,采用倾向得分匹配方法全面系统地评估了环境约束对外资企业研发创新的影响。结果表明：环境规制与外资企业研发创新存在显著的相关关系,其对外资企业研发创新的影响不仅具有即时性,同时具有持续性;此外,研究还发现环境规制对不同行业类型外资企业研发创新的影响也存在差异。
