关键词： 治安学   基本范畴   内在逻辑关系  

摘要： 治安学的基本范畴是治安学范畴体系的重要组成部分。从简单到复杂,从抽象到具体而言,治安学基本范畴是由起点范畴(违法犯罪)、中心范畴(治安防控)、中介范畴(治安主体与治安客体、治安行为与治安发展、治安资源与治安规范)和终点范畴(公共安全与治安秩序)构成的紧密联系、相互作用的立体动态体系架构。

关键词： Classification   Ecological traits   Functional group   Endogeic   Epigeic   Anecic   Epi-anecic  

摘要： In the early 70s, the soil biologist Marcel Bouche classified French earthworms species into defined ecological categories. This classification system was immensely successful and is still widely used to describe earthworm functional groups even outside of Europe. Bouche used morpho-anatomical traits to differentiate three main categories: epigeic, anecic and endogeic. However, the way species are assigned to a category was not explicitly described in Bouche's work. Thus, some earthworm species can still be assigned to two categories depending on the way researchers interpret Bouche's description. To solve these issues and avoid unnecessary controversies, we applied PCA and random forest models to the seminal data of Marcel Bouche (earthworm morpho-anatomical traits). Their assignment to Bouche's three main categories allowed us to statistically redefine the different categories and determine which traits are the most influential. We found that the three main traits were skin pigmentation (from none to black), body length (mean of the minimal and maximal values) and skin coloration (yes or no), followed by 10 other morphological and anatomical traits. We then used this approach to assign a likely category to all of the species studied by Bouche, resulting in a new triangular graph including other categories such as epi-anecic, endo-anecic, epi-endogeic and intermediate. Finally, we calculated the percentage that each species belongs to each main ecological category. This represents a paradigm shift and may change our vision of earthworm communities enabling the computation of the percentage of anecic, endogeic and epigeic species at the community level and thus overcoming the limits and debate about fixed ecological categories for each species.

关键词： 面子   次范畴面子   CCL语料库   语用功能  

摘要： 现代汉语中面子概念是一个极为复杂的问题,近年来,对其研究也是层出不穷,常常与人情、身份、文化相结合。基于CCL语料库,通过对比面子的明示性表达的语用功能,进一步阐释并分析现代汉语中面子的次范畴表达的区分语用功能。主要发现次范畴面子表征的语用功能主要包括:产生(不)礼貌,表达明示性情感和实现修辞效果。认为汉语中的面子可以通过主范畴面子(面子的明示性表达)和次范畴面子来表征,但它们具有区分性的语用功能。

关键词： 乡村   概念辨析   类型划分   演化规律  

摘要： 推进乡村振兴,必须对乡村的范畴、类型与演化规律有所把握,这是实施乡村振兴战略的基础性问题。当前,人们对乡村的概念范畴存在诸多的误读与误用。澄清认识误区,需要结合国际经验及历史进程,对乡村与农村、乡村与城市、乡村与郊区、乡村的类型、乡村的演化规律等内容进行专门讨论。乡村与农村的概念并没有本质区别,选用哪个概念应该依从语境和习惯。合理的城乡界定、完善的郊区形态和科学的乡村类型划分,在推进乡村振兴的过程中处于关键地位。通过对主要发达国家乡村演化规律的分析和把握,能够对中国乡村现代化的未来图景作出勾勒与展望。

关键词： 生产方式   双重逻辑   辩证运动  

摘要： 生产方式范畴的内涵及其与生产力、生产关系之间的关系问题一直是国内学界关注和研究的一个重大的理论与现实问题。在对生产方式的研究中,以往的倾向是将该范畴拘泥于狭小的视域,而忽视其与马克思思想整体的联系,这种偏离马克思思想脉络的研究倾向难以把握生产方式范畴的真义。将对生产方式范畴的研究置于马克思思想的整体视域之中,就会发现:生产方式具有一般物质生产的“生产逻辑”和特殊社会形态的“历史逻辑”的双重逻辑,而生产力、生产方式、生产关系三者之间的关系也并非简单的线性关系,而是存在着一种更为复杂的复合式关系。

关键词： 康德研究   概念主义   非概念主义   综合   范畴  

摘要： 概念主义和非概念主义之争是当代认识论中的一个重要话题,这场争论也渗透到康德学界形成了两种对立立场。非概念主义认为"无概念则盲"并不表明概念对于感知是必要的,形成感知对象所需的综合功能能够在非概念的条件下完成,且提出了一些感知的非概念特征;相反,概念主义则认为范畴在感知中扮演着不可或缺的角色,综合有赖于知性的作用,如果否认了概念在感知对象中的作用,先验演绎的任务就是失败的。相较而言,概念主义解读更有说服力,在康德那里范畴对于感知对象是不可或缺的,但康德式的概念主义并不同于麦克道威尔式的概念主义,前者能够在感知对象的基础上接纳广泛的非概念特征。非概念主义的论证,如精细论证与双手论证等等,对麦克道威尔式的概念主义有效但并不对康德式的概念主义有效。

关键词： 商务馆学汉语词典   说文解字   原型范畴   释义   职业义场  

摘要： 《商务馆学汉语词典》是我国第一部专门为具有中级汉语水平的外国人编写的汉语原文词典。它在字词、释义、词语辨析、插图等方面精雕细琢,风格独具特色,但对于同一语义场中的词在释义方面较为分散,缺乏系统化的释义模式。基于《说文解字》的启发和原型范畴的视角,根据《同义词词林》所列举的职业义场词作为引导,选取《商务馆学汉语词典》中职业义场里的44个常用词作为考察对象,列举释义,归类总结出这些词的释义原型,并进一步压缩整合,以此提出改良意见:基于原型范畴的释义模式能够为词典释义的规范化、精细化、系统化提供一个新的方向,可以有效地解决词典释义违背系统性原则这一普遍问题。
