服务模块化网络组织治理路径研究:风险悖论的视角

基于探索性案例研究方法和框架,立足风险悖论的视角,分别从点、线、面三个方面对农业产业网络风险悖论现象进行了探究。研究发现,过高、过低以及不完善的服务模块化设计均能够诱引农业产业网络组织风险生成,而产业网络的服务模块化结构在一定程度上又为其风险的形成路径提供了技术平台。为此,提出了三条农业产业服务模块化网络风险治理的优化路径,即通过优化网络节点模块的“公理化”设计来控制网络组织的风险源,通过优化节点模块松散耦合设计规范网络组织的风险传导途径以及通过优化网络界面规则标准化设计防止网络风险爆发。     

维特根斯坦"遵从规则"悖论及方法论启示

维特根斯坦在其后期的哲学研究中提出了遵从规则悖论。对此悖论,克里普克等人分别从怀疑论等角度提出了各自的解读方案。后来维特根斯坦为了消除人们对悖论的误读,他用语言游戏说及其方法论来解释“遵从规则”。维特根斯坦的语言游戏说认为,只有在语言游戏的实践中,才能谈得上遵从规则,才能理解语言的意义,才能体验到生活的价值,悖论也只有放到实践中才能解决。     

The practical paradox of technology: The influence of communication technology use on employee burnout and engagement

Technological advancements in the workplace frequently have produced contradictory effects by facilitating accessibility and efficiency while increasing interruptions and unpredictability. We combine insights from organizational paradoxes and the job demands–resources model to construct a framework identifying positive and negative mechanisms in the relationship between communication technology use (CTU) and employee well-being, operationalized as work engagement and burnout. In this study of Dutch workers, we demonstrate that CTU increases well-being through positive pathways (accessibility and efficiency) and decreases well-being through negative pathways (interruptions and unpredictability). We highlight the importance of (1) investigating CTU resources and demands simultaneously to grasp the relationship between CTU and employee well-being, and (2) considering CTU's downsides to successfully implement new communication technologies and flexible work designs.     

儿童归纳推理基础理论探索

儿童归纳推理基础之争,实质是信息加工自上而下还是自下而上的问题。在儿童归纳推理研究中应该重视概念知识的作用。概念发展对归纳推理研究有决定性的影响。将归纳推理按个体的知识领域丰富与否进行划分,分成知识丰富领域归纳推理和知识贫乏领域归纳推理。在知识贫乏领域内进行的归纳推理可能是基于知觉信息的,形成类似“像某某的东西有……属性”概念;在知识丰富领域内进行的归纳推理可能是基于概念或理论的,形成类似“某某类的东西有……属性”的概念。     

From Retrieval Status Values to Probabilities of Relevance for Advanced IR Applications

Information Retrieval systems typically sort the result with respect to document retrieval status values (RSV). According to the Probability Ranking Principle, this ranking ensures optimum retrieval quality if the RSVs are monotonously increasing with the probabilities of relevance (as e.g. for probabilistic IR models). However, advanced applications like filtering or distributed retrieval require estimates of the actual probability of relevance. The relationship between the RSV of a document and its probability of relevance can be described by a normalisation function which maps the retrieval status value onto the probability of relevance (mapping functions). In this paper, we explore the use of linear and logistic mapping functions for different retrieval methods. In a series of upper-bound experiments, we compare the approximation quality of the different mapping functions. We also investigate the effect on the resulting retrieval quality in distributed retrieval (only merging, without resource selection). These experiments show that good estimates of the actual probability of relevance can be achieved, and that the logistic model outperforms the linear one. Retrieval quality for distributed retrieval is only slightly improved by using the logistic function.     

中国近代新女性建构中的悖论——以吕碧城为个案研究

吕碧城是近代中国历史上被《大公报》等京津媒体所传诵的新女性的代表人物,其通过宣扬、兴办女子新式学堂和提倡女权运动成为近代历史上少有的颇具女权思潮的人物,但综合她其他方面的成就和人生经历,我们不难看出,她仍然是一个怀有古典情操的“旧式才女”。在晚清社会时空和吕碧城个人的生活际遇中,可以窥见晚清新女性如何在传统和现代的悖论中挣扎以及实现自我价值。     

认知语境对日常话语交际的语用制约功能

语言交际是一个认知推理过程,而认知推理则离不开语境的作用。交际双方的认知语境趋于一致,交际才能成功进行。本文通过对大量日常话语交际的分析,探讨认知语境在日常话语交际中的语用制约功能,认知语境对正确理解话语信息具有重要意义。     

Organizing youth work(ers) through the paradox of play

A recent focus among communication scholars, the study of contradiction and paradox illuminates the inherent irrationality of organizing. The following case study examines how youth labor – cast as play – functions as a series of tensions and contradictions in the day-to-day construction of work(er) between adults and youth. Mirroring the popular reality TV show, The Apprentice, the program under study communicated contradictory messages about youth work(ers) in terms of: (1) proving/discounting oneself as worker, (2) demanding confidence while orchestrating uncertainty and (3) playing along versus being playful in the organizationally prescribed framework, effectively dismissing work(ers) essential to the functioning of the organization. My analysis demonstrates how the framing of youth’s work as a game delegitimized youth work(ers) resulting in potentially exploitative working conditions, and serves as a call to communication scholars to better account for youth as workers, while pointing to similar implications for other types of provisional and contingent work(ers).     

话语标记“说实话”的形成和功能分析

文章讨论了"说实话"由动宾短语到话语标记的演变过程、变体形式以及话语标记"说实话"的解说、总结、衔接等三种篇章功能和主观评价、人际互动两种人际功能。另外,我们通过分析得出"说实话"虚化为话语标记的动因是主观化和交互主观化,机制是重新分析和语用推理。
