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。     

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.     

历史课堂中如何转变学生的学习方式

传统的教学方法是"口耳授受",即"老师讲,学生听".在这种教学方法指导下,许多学生只习惯发挥大脑储存的功能,而不习惯发挥大脑的思维功能,整天读呀、记呀、背呀,不但学习负担很重,而且收效并不理想.

川东中高山地区红三叶－黑麦草人工草地刈割演替研究

本文试图对具有特殊建植目的和特殊利用方式的人工草地进行刈割演替研究。从重要值、演替距离等方面分析了不同刈割处理红三叶－黑麦草人工草地植物组成变化、群落演替趋势及群落稳定性。提出了红池坝红三叶－黑麦草人工草地建设可能出现的目标群落。认为红三叶－黑麦草人工群落刈割过重将朝黑麦草－红三叶方向发展，刈割过轻将朝灰苞蒿－红三叶－黑麦草方向发展。并进一步指出红三叶盛花期一年３次刈割的条件下，红三叶－黑麦草群落最为稳定，１ａ２－４次刈割是其刈割利用的“安全区”。     

治学道德的凝视：何以规范研究生学术道德

借助对“凝视”这一关键词的文本分析和解读,以治学道德对研究生学术道德的“凝视”为新的切入视角,在高校“双一流”建设的社会语境和学术语境下探寻治学道德对规范研究生学术道德的理论建构和策略理解。基于治学道德“凝视”的规范研究生学术道德的新理路在于：加强制度设计,建立规范研究生学术道德的新准则;加强法制教育,提升研究生学术道德自律的新境界;加强道德治理,建构师生学术道德共同体的新关系。     

基于Lotka-Volterra模型的创新扩散模式研究

借用生物学中著名的Lotka-Volterra模型对具有相互影响关系的创新扩散问题进行了深入分析.研究表明,在创新扩散过程中存在三种作用模式:竞争模式,两类创新相互抑制;互利共存模式,两类创新相互促进;捕食模式,一类创新的存在促进另一类创新的发展,而同时后者又抑制前者的发展,反之亦然.由于创新的性能、价格等影响市场竞争的因素随时间而变化,两类创新之间的作用模式也会随之在这三种模式之间相互转化.
