“三要素”：逻辑悖论研究的历史性界标--张建军教授逻辑悖论研究思想探赜

张建军教授析出的逻辑悖论“三要素”,即“公认正确的背景知识”“严密无误的逻辑推导”和“可以建立矛盾等价式”,为澄清逻辑悖论的本质认识及其基本结构奠定了基础。“三要素”内在地包含了分析逻辑悖论的基本方法,解决逻辑悖论的基本路向,以及解决逻辑悖论的一般评准,为充分发挥逻辑悖论研究的方法论功能与认识论价值奠定了基础。“三要素”在逻辑悖论研究的历程中具有历史性界标意义。

基于本体论的数字图书馆搜索引擎的研究

基于本体（ontology）理论,利用本体对概念、术语及其相互关系的规范化描述,勾画出数字图书馆领域的基本知识体系,构建了数字图书馆领域本体库;然后,对现有的图书馆搜索引擎系统进行了改进,将构建的本体库引入到系统中,实现了基于本体的信息检索,方便用户对资源的查询,为用户提供高质量的个性化服务。     

CyberBabel?

The new information technologies hold out the promise of instantaneous, 24/7 connection and co-presence. But to be everywhere at once is to be effectively nowhere; to be connected to everyone and everything is to be effectively disconnected. Why then do we long for faster connections and fuller connectivity? The answer this paper proposes is that we are trying to fill our existential lack, our radical sense of inadequacy and incompleteness as human beings. From such a perspective, our pursuit of speed and connectivity is doomed to failure insofar as it only exacerbates the condition we are fleeing. Rather than rushing faster, the Buddhist-inspired solution would have us slow down and directly investigate our sense of lack.     

技术创新的悖论与开放式创新

知识分子与大学的现代性悖论

在现代性合理化地建构秩序的境遇下,知识分子经历了从立法者到阐释与批判者、从＂异乡人＂到＂定居者＂的转向;大学在现代工具理性的压力之下也相应地走出＂象牙塔＂,踏进＂服务站＂而蜕变成＂多元化巨型大学＂并晋升为社会的＂轴心机构＂。随着学科知识的日益专门化、学术生活的日趋秩序化,知识分子获得来自＂多元化巨型大学＂的承认越多,其对抗正统与教条,不轻易被政府或集团收编,对权势阐释真相的独立本性与批判潜能则越少。此一现代性悖论,是高教研究直接承担社会责任的一道玻璃墙。     

临界频率和非临界频率——频率和语法化关系的重新审视

以往人们对频率—语法化关系的研究多建立在笼统意义的频率基础上,这在理论和实证上都遇到了问题。频率对语法化的影响是通过语用推理来实现的,因而有必要区分语法化项在具备语用推理条件和不具备语用推理条件两种环境下的频率,即临界频率和非临界频率。语法化受到前者的直接推动,但与后者并无关联。     

解析作为解悖方案的弗协调逻辑

弗协调逻辑是一种可以容纳“矛盾”的非经典逻辑,其所容纳的“矛盾”被称为“真矛盾”。在弗协调逻辑看来,逻辑悖论就是一种“真矛盾”,是可以被弗协调逻辑系统所容纳的。在分析逻辑悖论语法表现的基础上,我们可以清楚地看到弗协调逻辑消解悖论的逻辑机制。弗协调逻辑作为一种解悖方案,实际上是隔离了悖论对系统的不良影响,这种隔离意义上的悖论消解具有重要的现实意义;同时其相对于协调而区分出来的弗协调,也具有重要的逻辑哲学价值。     

仁者“力行”:教学悖论与教师自由实践

教学悖论指教师教育教学过程中存在的必须解决却永难得到答案的一系列困惑与矛盾,如语言暴力与无言之教的悖论、规训与自我创造的悖论、理想之境的描绘与苦难之境的揭示之间的悖论、功利追求与精神修养的悖论等等。教学悖论对教师的自由实践造成了重大影响。教师自由实践的本质和精髓在"力行",教师权力的真正体现也在"力行"。教师的自由实践是一种精神实践,也是一种科学的政治实践。教师自由实践的最高境界表现为教师能进行原创性教学,即教师创造课堂、教师创造学生。而这一切自由实践的根本则在教师能够自我创造。     

How does collaboration affect researchers’ positions in co-authorship networks?

Collaboration usually has a positive effect on researchers’ productivity: researchers have become increasingly collaborative, according to recent studies. Numerous studies have focused on enhancing research collaboration by recommendation technology and measuring the influence of researchers. However, few studies have investigated the effect of collaboration on the position of a researcher in the research social network. In this paper, we explore the relationships between collaboration and influence by social analytical methods, which are pertinent to analyzing the network structure and individual traits. We evaluate three aspects of the researchers’ influence: friendship paradox validation, social circle, and structure of a researcher's ego network. Furthermore, the ”six degrees of Bacon number” theory, generalized friendship paradox, and triadic closure theory are introduced to support our analysis. Experimental results show that collaboration can help researchers increase their influence to some extent.
