技术设计：技术认识的形象化

技术设计是运用设计理论和方法，在创制和改造技术人工物的过程中，把思维中的技术构思规范化、定量化，把它们以标准的图纸或说明书的形式展现出来的创造性活动。技术设计是解决技术问题的关键，通过分析问题、综合取舍、实践评估等环节使得抽象的技术认识得以形象化、具体化，从而形成切实的技术问题解决方案。在不同的认识情形下，技术设计或者被当作一个黑箱，或者被当作一个白箱，或者被当作一个系统，这三种不同的设计方式分别反映出技术设计的创造性、合理性和过程控制。     

Acceptance of automation manufacturing technology in China: an examination of perceived norm and organizational efficacy

Abstract

With a shift to more automation technology, social acceptance of technology plays an important role in the manufacturing sector. To what extent this occurs, and affects the adoption of technology, has been less researched, but is important in deciding how such technology is introduced, and the nature of the shift from labour-intensive manufacturing to automation. This research applies the revised technology acceptance model (TAM) to examine the impact of social and individual antecedents on the acceptance of automation manufacturing technology. Survey data are collected from 258 Chinese manufacturers. Results suggest that perceived norms significantly affect organizational intention to use automation manufacturing technology both directly and via perceived usefulness; organizational efficacy explains the intention to use via mediating effect of perceived usefulness and perceived ease of use. This research is one of the first extending and applying TAM from individuals to organizations.     

技术特征、关系结构与社会化购买行为

社会化媒体技术与社会关系网络促进了社会化商务(SC)的价值创造，如何有效利用技术与用户的关系结构是 SC 企业提高其平台购买转化率的关键． 从双重视角探索技术与关系如何影响用户购买决策，基于刺激―机体―反应框架，构建了以技术可供性和强、弱关系为刺激因素，信息诊断性和意外发现性为内在机体状态，社会化购买意向为“反应”的理论模型，探索了用户社会化购买行为的发生机制． 以具有社会化购买体验的微信用户作为研究对象，运用 SmartPLS 3.0 对模型进行了路径检验和假设分析． 研究结果发现: 技术可供性与弱关系对信息诊断性和信息意外发现性具有正向影响; 弱关系对信息意外发现性的影响作用大于强关系; 信息诊断性正向影响信息意外发现性，信息诊断性与意外发现性对社会化购买意向均有显著正向影响; 然而，强关系对信息意外发现性的影响不显著． 信息诊断性与信息意外发现性部分中介了技术可供性对社会化购买意向的影响，完全中介了弱关系对社会化购买意向的影响，信息诊断性部分中介了强关系对社会化购买意向的影响． 为进一步探究社会化购买行为提供 了理论基础和实践指导．     

Understanding public perceptions of genetically modified organisms in China: The role that heuristics play during digital media exposure

This study explicates the role that heuristics play in influencing Chinese public perceptions of genetically modified organisms (GMO) when they are exposed to digital media. According to the cognitive–affective continuum of heuristics, trust in scientists and negative emotions about GMOs are a cognition-oriented heuristic and an affect heuristic, respectively. The statistical results of an online survey (N?=?414) demonstrated that trust in scientists fully mediated digital media exposure and perceptions of the risks versus benefits of GMOs. In addition, negative emotions moderated the full mediation effect, showing that the indirect effect was stronger in individuals with low levels of negative emotions than in those with high levels of negative emotions. The mediating role of trust in scientists and the moderating role of negative emotions, the two heuristics applied in this study, indicated that when negative emotions were weak, laypeople were more likely to rely on scientists to judge the consequences of GMOs than systematically process the associated information by themselves. The findings have implications for reconsidering the importance of heuristic processing in building reasonable public perceptions of risk-laden technologies through the digital environment.

基于碳减排技术的竞争供应链投资均衡策略研究

本文以两条竞争供应链（每条供应链均包含一个制造商和一个零售商）为研究对象，基于其是否采用碳减排技术，构建了两条供应链均不采用碳减排技术（NN情景）、供应链1采用碳减排技术（AN情景），供应链2采用碳减排技术（NA情景），及两条供应链均采用碳减排技术（AA情景）的收益模型，求解出相应的最优解并探讨了竞争供应链投资碳减排技术的均衡策略。研究发现：当碳税较低时，AA情景是竞争供应链的均衡策略；当碳税适中时，生产成本较高的供应链不采用减排技术，而其竞争供应链将采用减排技术以提升竞争力；当碳税较高时，NN情景是竞争供应链的均衡策略。此外，当供应链间竞争强度较弱时，政府可适当提高碳税标准；当供应链间竞争较为激烈时，政府应降低碳税以引导企业采用碳减排技术。     

论数字货币的私法性质——以日本Bitcoin.Cafe数字货币交易所破产案为中心

数字货币，是一种具有财产性价值属性的电磁记录型数据。数字货币在其依存的区块链体系中所彰显的与不特定者之间的支付对价性、与法定货币之间的互换性、使用电子信息处理系统进行转移的在线转移性等特点，得以从数据说的角度，将其作为一种数据性财产权在现行法律框架内对其私法性质进行讨论。有鉴于我国民法总则已将数据纳入保护客体的范畴，数字货币作为数据之一种，理应成为一种新型法律客体，在得到法律理论支撑的基础上获得保护。     

The problem of intersectionality as an approach to digital activism: the Women’s March on Washington’s attempt to unite all women

ABSTRACT

This study examined the convergence of activism and intersectionality to understand how communicators create messages about social justice issues using social media. This is particularly relevant for public relations today, as digital activism almost ubiquitously involves bringing together conflicting publics who are active and social media-savvy, meanwhile maintaining an organizational brand/mission. Using the 2017 Women’s March on Washington (WMW) as an object of study, we explored how campaign messages reflected principles of intersectionality, consensus- and dissensus-based communication, and organizational self-reflection. We conducted a thematic analysis of posts from the WMW’s social media accounts as well as media quotes by the organizational leaders to get at the leaders’ intentions in their message design. Data suggested that messages of inclusivity as well as of necessary discord were employed to enact political change for WMW’s publics. We argue that although the WMW was not wholly intersectional, particularly in determining its political agenda, the efforts toward intersectionality are notable for theory-building and reflective practice, particularly for social mediated campaigns. The study proposes a theory for digital intersectional communication to guide future research and advocacy work.     

Digital learning across cultures: an account of activity theory

ABSTRACT

This paper explores a teaching and learning process as it unfolds in an online offshore classroom. The paper reports on teaching and learning narratives distilled from different cultures, namely the cultures of educators and students in the context of digital learning environments. Drawing on activity theory as a conceptual framework to analyse the narrative, we employ self-study as a methodological tool for capturing the dynamism and complexities that unravel in intercultural and technology-enabled teaching activities. The framework explores the relationships, tensions and opportunities of diverse activity elements that constitute the design and delivery of digital pedagogies. In the networked intercultural system, sustaining the position of activity elements and the specific relational circuit that they institutionalise is a key task for understanding digital technologies as an influential tool for effective learning and teaching practices. We argue that seeing the digital platform from the perspective of its role in creating dynamic interrelationships in a complex activity system is one way to move beyond the cultural confines of any particular element in the system.
