符合工程化需求的生物元件设计

从合成生物学的角度来认知生命,其本质是可数据化与可设计性。生命体中绝大多数的催化功能是由酶来实现的,因此催化元件是合成生物学中最核心的元件之一。序列决定构象,而构象则决定功能。基于空间结构的催化元件序列数字化设计,是合成生物学研究的重要热点和前沿领域。它既可为开发合成生物学功能器件,特别是全新化学催化器件提供大量原型分子,同时也为发展模块化、工程化调控元件提供设计模板和指导规律。文章针对近年来出现的生物元件,尤其是催化元件的前沿进展进行简要介绍。     

学术期刊论文非信息成分探析与规避策略

从编辑实践与科技论文学术生态出发,剖析学术期刊论文中非信息成分的表现形式、危害及成因,分别从作者、编辑和期刊体系等方面提出了对应规避策略,旨在提高学术期刊的信息价值与论文质量,降低或消除论文中的非信息成分,还原科技论文的科学性、严谨性与规范性,使科技信息资源得到高效共享与利用.     

风险投资环境支持体系和谐构建机理研究

风险投资环境支持体系主要包括经济、文化、科技、金融、中介服务机构等环境要素,这些要素又可以分为宏观层、中观层和微观层三个层次。根据系统论的观点,各个层次内部的要素之间以及层与层之间都存在着相互作用、彼此协同的关系。通过分析层内各要素间及层与层之间的协同作用,以探讨整个环境支持体系的和谐构建机理,希望对我国风险投资环境支持体系的构建有所裨益。     

Children can represent complex social status hierarchies: Evidence from Indonesia

Children's ethnicity-status associations are often studied in societies where one ethnic group possesses status across multiple dimensions, such as political influence and wealth. This study examined children's (6–12 years) and adults' representations of more complex hierarchies in Indonesia (N = 341; 38% Native Indonesian, 33% Chinese Indonesian, and 27% other ethnicities; 55% female, 36% male; 2021–2022), a society where ethnic groups hold distinct forms of status (on average, Native Indonesians have political influence; Chinese Indonesians have wealth). By 6.5 years, children associated Native Indonesians with political influence and Chinese Indonesians with wealth. Intersectional analyses indicated that ethnicity-status associations were stronger for male than female targets. Children of all ethnicities preferred Chinese Indonesians and preferences were predicted by wealth judgments.
