功利主义的德性伦理可行性探索

功利主义思想由于缺乏对行动者问题的关注而受到德性伦理等相关伦理思想的批判,但行动者中心的伦理理论又不是自明的。在分析功利主义的特征以及以伯纳德.威廉斯为代表的德性伦理思想家对功利主义忽视"个人完整性"的批判的基础上,我们可以放弃作为决策程序的功利主义,保留功利主义作为一种正当性标准,通过改进黑尔的道德思维层次理论使道德思维的直觉层次与反思层次分别关系于行为者与行为,使功利主义在道德教育和制度设计等方面发挥引导行为倾向、塑造道德人格的作用,可以看做是构建功利主义的德性伦理的一种可行性尝试。     

大学生入党积极分子思想动态分析及教育对策

通过实地调查,并运用SPSS13.0数据分析软件进行数据统计,分析比较了高校不同群体入党积极分子的真实思想动态及差异性。为增强大学生思政教育工作的针对性、实效性,从"教育引导目标定位、树立人本价值观、党务工作队伍建设、保持学生党员的先进性教育、处理好学生党员数量与质量的关系"五个方面提出了积极的应对措施。     

高校线上线下混合一流运筹学课堂建设探讨

高校教师职称评审工作现存问题及对策研究

高校职称评审工作关系到能否充分激发广大教师工作的积极性及创新性,关系到我国高等教育事业的持续、稳定、健康发展。现行的高校教师职称工作中出现了比如高校管理机制中职称评审分工不明确、评审标准异化、评审材料弄虚作假、评审过程失范等问题。在此基础上提出相应的对策,这对新时期完善高校教师职称评审工作、提高教师水平和教学质量具有重要的理论和实践意义。     

多维教育在大学和职高中的应用对比研究

随着中国与世界其他国家的交流越来越频繁,英语作为一种重要的交流工具,彰显的作用越来越明显。在语言知识的教学过程中,英语教学取得了举世瞩目的成就。但是,也有很多多维。在传统的英语教学过程中,以考试为中心的教学模式的弊端主要体现在学生英语水平的实际应用和学生自身能力的提高上。因此,在英语教学过程中,如何改变教学观念,深入探索课堂教学,以提高英语教学效率,从而全面发展学生的自主性、主体性和英语能力已经成为当代英语教学改革过程中的一个主要多维。这项研究的目的是为职高英语课程构建一个多维互动式教学模型。通过改变教学方法,我们努力提高学生的英语学习能力,培养学生对语言技能的综合利用,并促进深度学习。     

Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing

Complex oxides with tunable structures have many fascinating properties, though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach. Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic (1-x)BiTi_(1-y)/2Fe_yMg_(1-y)/2O₃–(x)CaTiO₃ (BTFM–CTO) solid solution in large area, confirming its ferroelectricity at the atomic scale with strong spontaneous polarization. Careful compositional tuning leads to a bulk magnetization of 0.07 ± 0.035 μ_B/Fe at room temperature, enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0 × 10⁻⁷ s/m. This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film, making it possible to explore a much wider space of composition, phase, and structure that can be easily scaled up for industrial applications.     

Research ethics: a safeguard for advanced technologies

With the fast development of cutting-edge technologies and their greater integration into human life, more ethical challenges emerge. The problem became more salient when the world''s first genetically edited babies were born in China in violation of existing ethical rules. Although the responsible researcher He Jiankui was sentenced for imprisonment for three years last December, it is still necessary to examine the current status of research ethics and the challenges in China. Has China set up a sophisticated research ethics system? For research ethics and their implementation in China, are there unique national characteristics? Can the dominant ethics principles primarily developed from life science research be equally adopted in the emerging artificial intelligence research and development? At an online forum organized by National Science Review (NSR) and through subsequent correspondences among forum participants, NSR Executive Editor-in-Chief Mu-ming Poo and guest moderator Hepeng Jia asked three scientists and three bioethicists or philosophers of science and technology in the field to examine the dynamic development of research ethics in China.
