使用词汇化句干对二语语用能力的影响

大多数语言中均普遍存在相当数量的词汇化句干，此类语言信息块的使用能够缩短使用者话语输出的编码时间，提高理解语言输入的解码效率。故此，二语学习者需要增强对目标语语块信息的注意力，将之内化进而提高二语语用能力。词汇化句干对中介语发展的实证研究表明，词汇化句干的使用将促进中介语的发展。

The social security number: A small device underpinning big systems

The possession and use of a personal social security number helps to structure people's daily lives. However, despite its fundamental normative importance, the social security number remains a little‐known entity. Increasingly universal and yet diverse in form, it is a legal and technical norm which is as much a mechanism for surveillance and monitoring as it is a necessary instrument for giving effect to social rights. Analysis of this constituent element of social security systems permits as assessment of some of the technical difficulties presented by the ever‐increasing movement of people and data. Overcoming these technical difficulties should permit to envisage a first technical step towards realizing a universal and global social security system.     

Cloud manufacturing system for sheet metal processing

Abstract

Cloud computing is changing the way industries and enterprises run their businesses. Cloud manufacturing is emerging as an approach to transform the traditional manufacturing business model, while helping the manufacturer to align production efficiency with its business strategy, and creating intelligent factory networks that enable collaboration across the whole enterprise. Many production planning and control (PPC) problems are essentially optimisation problems, where the objective is to develop a plan that meets the demand at minimum cost or maximum profit. Because the underlying optimisation problem will vary in the different business and operation phases, it is important to think about optimisation in a dynamic mechanism and in a number of interlinked sub-problems at the same time. Cloud manufacturing has the potential to offer decision support as a service and medium of communication in PPC. To solve these problems and produce collaboration across the supply chain, this paper provides an overview of the state of the art in cloud manufacturing and presents a model of cloud-based production planning and production system for sheet metal processing.     

社会网络、 先前经验与创业风险识别

无法识别创业风险是导致创业失败的主要原因之一,如何有效识别并管理创业风险是新创企业健康成长的关键.社会网络能够弥补创业者在识别风险过程中的信息劣势,但既有研究极少探索社会网络是否以及如何影响创业风险识别.为弥补这个研究空白,文章利用信息处理理论为研究框架,构建了创业风险识别模型.具体而言,结构洞和网络强度有利于创业者获取更多、高质量与风险相关的信息,进而识别更多的创业风险;获取信息的数量在网络强度与创业风险识别关系之间发挥完全中介作用;创业者的先前经验正向影响创业风险识别,并对结构洞与获取信息的数量之间关系起调节作用.文章讨论了研究结果的理论贡献与实践启发.

How Mood and Task Complexity Affect Children's Recognition of Others' Emotions

Previous studies examined how mood affects children's accuracy in matching emotional expressions and labels (label‐based tasks). This study was the first to assess how induced mood (positive, neutral, or negative) influenced five‐ to eight‐year‐olds' accuracy and reaction time using both context‐based tasks, which required inferring a character's emotion from a vignette, and label‐based tasks. Both tasks required choosing one of four facial expressions to respond. Children responded more accurately to label‐based questions relative to context‐based questions at the age of five to seven, but showed no differences at the age of eight, and when the emotional expression being identified was happiness, sadness, or surprise, but not disgust. For the context‐based questions, children were more accurate at inferring sad and disgusted emotions compared with happy and surprised emotions. Induced positive mood facilitated five‐year‐olds' processing (decreased reaction time) in both tasks compared with induced negative and neutral moods. Results demonstrate how task type and children's mood influence children's emotion processing at different ages.     

The Role of Social Goals in Bullies' and Victims' Social Information Processing in Response to Ambiguous and Overtly Hostile Provocation

Understanding what social goals are associated with bullying and victimization behaviours, even after allowing for biases in interpretation of and affective responses to social events, is critical for understanding the socio‐behavioural profile of bullies and victims. In the present study, 181 nine‐ to ten‐year‐olds' affective responses, attribution of intent, and social goals were assessed in the context of a series of ambiguous and overtly hostile provocation vignettes. Results showed that even after allowing for other social information processing biases, social goals were meaningfully associated with bullying and victimization scores. Bullying was inversely associated with relationship‐building goals, and positively associated with goals to be assertive over the provocateur when provocation was overtly hostile. Being victimized was associated with having submissive goals even when provocation was ambiguous and after accounting for attribution of hostile intent. Findings are discussed in light of theoretical and practical implications.
