The persistent epidemic of human mpox, caused by mpox virus (MPXV), raises concerns about the future spread ofMPXV and other poxviruses. MPXV is a typical zoonotic virus which can infect human and cause smallpox-likesymptoms. MPXV belongs to the Poxviridae family, which has a relatively broad host range from arthropods tovertebrates. Cross-species transmission of poxviruses among different hosts has been frequently reported andresulted in numerous epidemics. Poxviruses have a complex linear double-strand DNA genome that encodeshundreds of proteins. Genes related to the host range of poxvirus are called host range genes (HRGs). This reviewbriefly introduces the taxonomy, phylogeny and hosts of poxviruses, and then comprehensively summarizes thecurrent knowledge about the cross-species transmission of poxviruses. In particular, the HRGs of poxvirus aredescribed and their impacts on viral host range are discussed in depth. We hope that this review will provide acomprehensive perspective about the current progress of researches on cross-species transmission and HRGvariation of poxviruses, serving as a valuable reference for academic studies and disease control in the future.

抗草甘膦转基因油菜和野芥菜回交1代子2代-子6代在无除草剂选择压下的适合度转基因作物的抗性基因能否成功渗入野生或近缘杂草取决于携带转基因回交后代的适合度。为深入了解转基因油菜(Brassica napus)向野芥菜(wild ***)基因流动的生态风险,本文研究了在低密度(5株/m^(2))和高密度(10株/m^(2))下,以及单种和混合种植(野芥菜:BC1F2R-BC1F6R=1:1)下抗草甘膦转基因油菜与野芥菜回交1代子2代到子6代(BC1F2R-BC1F6R)的适合度;并分析回交后代的适合度成分、种植密度和种植方式之间的相关性。研究结果表明:在单种低密度下,与野芥菜相比,回交1代子2代(BC1F2R)和子3代(BC1F3R)具有较低的适合度,而回交1代子4代-子6代(BC1F4R-BC1F6R)具有较高的适合度;无论是单种还是混种,高密度下所有回交后代的适合度均低于野芥菜。相关性分析结果显示,种植密度和种植方式对回交后代(BC1F2R-BC1F6R)的适合度成分有显著影响。这些结果表明,转基因从栽培油菜渗入到野芥菜很大程度上取决于回交后代的特定生长环境。

作为一种介入实践并改变实践的研究方式,教育实验在教育学追求科学化的进程中产生,并作为科学化的典型代表,推动教育实践的变革和教育学的发展。教育实验理应肩负起促进教育知识生产的使命。但与此相反的是,在追求科学化的教育实证研究的当下,教育实验却日渐式微。造成这一局面的原因,既有教育研究多样化发展的趋势所向,也有后实证主义对严格实证研究范式的批判,以及实验法本身在教育领域的局限性和实证研究的异化、窄化等因素。中国教育学自主知识体系的建构需要有基于中国教育问题和教育实践的教育研究。教育实验的未来发展,需要明确和强调实证研究的主流并非是静态的、现成数据的多重技术分析,而应该是真正介入并改变教育实践的高质量行动研究和实验研究。教育实验本身也应摒弃单一的理性认识和对过程的强控制,重构具有实践关怀和教育志趣的教育实验观,注重实验过程的“软”控制和方法的多元融合。同时,要鼓励那些自然状态下的学校教育实验,鼓励民间教育团体的积极参与;通过营造一种鼓励多元、良好的教育科研评价环境,扭转功利、浮躁的教育科研氛围。唯有如此,才能够有效地促进教育实验和教育研究的发展,推动我国教育理论与实践的变革与进步。

空间塑造着主体,而主体与空间的交互又再造了空间。现代学校教育空间基本延续了工业时代的特征,其标准化、封闭性和分割性的特征服务于个体的客观知识增长这一教育生产目的。它顺应了工业社会对批量人才的需求,促进了教育的制度化发展和现代化进步,但也造成了割裂、限制和规训等问题。而当下功利和异化的教育观念与目的也凭借空间再生产出针对性的制度与规范;这些制度与规范在空间中运行发挥其管理学功能,并通过空间得以管控空间主体的身体及其行为,使规训得以实现,异化的权力关系也得以形成。传统学校教育空间的沿用已经阻碍了新教育理念的落实,亦限制了新型教育空间样态的产生。学校教育空间的改造,需要在满足必要的标准和基本生理学与教育学保障的基础上,努力寻求更多的开放性、动态交互性与多样化的发展,以满足当下教与学的本真需要,真正推进教育改革、促进学生的学习与发展。

在民族高校开展红色教育,对于传承红色文化、加强民族团结、铸牢中华民族共同体意识等方面具有重大意义。本研究通过回溯民族高校红色教育的历史源流,旨在发掘其优良传统,彰显其突出特征。民族高校红色教育的优良传统在于各个时期党的民族政策始终强调红色教育,民族高校的建立和发展始终以红色为底色,中国共产党各个时期针对中华民族的红色教育成绩斐然。民族高校红色教育的特点主要表现为坚持党的领导、全面推进中华民族伟大复兴、体现“两个结合”和维护国家安全四个方面。现阶段民族高校红色教育以铸牢中华民族共同体意识为旨归,通过思政教育课程、在特色课题研究中注入红色基因、发掘革命文化遗产、依托红色办学传统等形式开展。但目前该教育尚存在教学松散、路径狭窄、实践方式单一、系统性不足等问题。民族高校应通过设立“阶梯式”教学体系、“并联式”研究体系、“复合式”实践体系以及“闭环式”考评体系这四大体系来改善和加强红色教育。
