访谈中,张江教授认为,从“强制阐释”走向“公共阐释”的研究历程,揭示了阐释的边界性与公开性,而从传统训诂学等中国本土阐释学的独特方法入手,提出“阐衍学”的新颖概念,则既能够为训诂开拓出一个广阔的阐释前景,又能够为阐释打牢可靠的中国根基。因此,当代中国阐释学研究应当在吸收借鉴西方阐释学优秀理论成果的同时,深入挖掘博大精深的中华文化所蕴藏的丰富阐释学思想资源,使之融入新时代中国学术自主知识体系的有机组成部分之中,并结合时代精神和生活实践对其加以提炼和升华,实现现代转化,推动形成更加科学、更可持续、更具世界意义和历史意义的阐释学理论,从而成为我们把握当代生活、凝练时代主题的有效工具。

Dear Editor,RNA-based pesticides are approaching the market,offering great potential to control agricultural pests such as the coleopteran insect Diabrotica virgifera virgifera(Head et al.,2017).However,application to lepidopteran pests has been hampered by their inconsistent response to RNA interference(RNAi).As a notorious lepidoptera pest,Helicoverpa armigera feeds on over 300 species of host plants(Fu et al.,2022).Although transgenicplants expressingdouble-stranded RNAs or microRNAs that target essential insect genes can inhibit the growth of larvae,complete protection of the plants and efficient killing of this insect have not been achieved(Bally et al.,2020;Chung et al.,2021;Li et al.,2023).The relatively low RNAi efficiency in lepidopterans is mainly attributable to the degradation and intracellular sequestration of double-stranded RNA(Shukla et al.,2016;Zhu and Palli,2020).To overcome these obstacles and improve RNAi efficiency in ***,we attempted to deliver RNAi molecules using a bacteriophage MS2 virus-like particle(VLP)-based delivery system(Wang et al.,2016).

为研究经济发展与碳排放的脱钩情况,常用对数平均迪式指数分解法(LMDI)结合Kaya恒等式和Tapio脱钩模型计算碳变化量和弹性脱钩指数.借鉴上述方法,将STIRPAT模型与LMDI分解法相结合,建立STIRPAT模型的回归系数与碳变化量和脱钩弹性指数之间的数量关系,研究影响碳排放各因素的脱钩状态.结果表明:(1)STIRPAT模型LMDI分解法能够避免满足Kaya恒等式的IPAT模型中使用LMDI分解法时增加新变量的情况,部分新增变量往往缺乏明确的经济学含义;(2)LMDI分解将STIRPAT模型中的统计回归系数的含义,由变量的变动引起碳排放量变动的弹性系数,扩展到变量的变动引起碳变化量的倍数;(3)STIRPAT模型LMDI分解法,将数据的统计结果通过统计回归系数纳入到各因素的碳变化量和弹性脱钩指数之中,使弹性脱钩指数能够反映数据的统计信息;(4)以重庆市2001~2019年碳排放数据为例,来说明STIRPAT模型LMDI分解法可以用于判定碳排放变量的脱钩状态,能够体现数据本身所包含的统计信息,更能反映研究对象的实际情况.

“义”与“意”是人类认知与阐释的核心概念。在汉语言文字体系中,义与意的来源、目的、认知取向均有深刻差异。义包含客观性、确定性,具有与关联对象本身的符合性,意则包含主观性、多元性,与关联对象本身疏离甚至对立。建构中国阐释学,需要辨识、处理好义与意的关系。由认识论的观点看,义在意先,要坚持先义后意的认识路线;意从义衍,阐衍组合,既要有开放交流取向,也要有合理限定,以实现最终合流;意要转化上升为义,由意而义、由价值而知识的认准不是简单的否定或肯定,而是接受公共理性检验的历史过程。人类实践是由义而意的无限上升,证明人类认知的确定性追求稳定而恒久。

阐释在公共空间中展开,以公共理性认准及认准程度为标志,使阐释成为公共阐释。公共空间、公共前提、公共理性、公共阐释,均以公共为基准。如此,确证公共本义,把握公共蕴含,成为认知阐释何在、阐释何能、阐释最终为阐释的根本问题。中国传统语言文字学对“公”与“共”及组合词“公共”多有涉及,近代以来西方多位思想家对此也有丰富论述,但两者差别甚大。在此语境下,以中国话语为基准,辨析和讨论“公共”之词义、语义、意义,寻求和确定阐释的公共性质与根据,对阐释论框架下的公共阐释具有根本性意义。人类的精神公共由阐而可能,由阐而实现,把握好阐与公共,在公共中创造,创造超越公共,将为人类精神进步开辟新的道路。
