数据赋能驱动制造业企业实现敏捷制造案例研究

  世界经济的发展呼唤先进制造理念和制造技术,敏捷制造受到学者的广泛关注。制造业企业通过了解实现敏捷制造的过程机理,可以使其灵活地运用各种先进生产技术促成敏捷制造。然而,已有对制造业企业实现敏捷制造过程的研究缺少契合当前情景的视角以及完整、清晰的探究。         鉴于此,引入赋能概念,从数据驱动的视角对青岛酷特智能公司的研发、生产和营销3个阶段进行深入分析,结合扎根理论的3级编码技术,构建制造业企业通过数据赋能实现敏捷制造的过程模型。在已有研究基础上,构建敏捷制造的开放式概念框架,通过调研访谈、实地考察等方式获得分析数据,分析并构建制造业企业实现敏捷制造的过程模型,结合已有研究对该模型进行进一步讨论和完善。研究过程严格遵循理论构建的理论-实践-理论研究逻辑。         研究结果表明,企业的敏捷制造能力可以通过高效对接消费者需求与资源以及提高中间对接环节的效率来打造。从数据驱动视角看,数据化、标准化和联网化是制造业企业实现敏捷制造的核心所在。一方面,数据化和标准化可以提高数据的可接入性和流通性,减少制造加工环节的延缓;另一方面,联网化可以让需求数据直接对接企业的资源和制造过程的设备,进而实现资源的自动整合,打造企业高响应速度、高质量、低成本的供给。         从数据驱动视角构建的敏捷制造过程模型系统详细地解释了制造业企业通过数据赋能实现敏捷制造的过程,完善和拓展了关于敏捷制造的研究,为未来敏捷制造实证研究提供了一定的研究基础和启示。此外,为了给企业实践提供更加详细、明确的指导,给出基于数据赋能驱动制造业企业实现敏捷制造的实践指导步骤。     

网络出版产品的定价模式浅析

伴随着科学技术突飞猛进的发展,我国经济发展方式转变的课题已被提到议事日程上来,发展文化产业无疑是其中的一条重要途径。网络出版产品是文化产业发展的重要组成部分,目前还未形成成熟的赢利模式,合理地制定价格有利于实现更大的利润,因而,对网络出版产品的定价模式进行探讨,明确了网络出版的定义及特征,实证分析目前我国网络出版产品现状以及定价过程中存在的问题,围绕网络出版产品的经济学特性,立足于几种基础价格理论,尝试解决网络出版产品"社会必要劳动时间"难以衡量这一难题,坚持马克思主义劳动价值论,科学制定网络出版产品的价格。     

Engaging stakeholders through Twitter: How nonprofit organizations are getting more out of 140 characters or less

While it may seem difficult to communicate in a meaningful manner with 140 characters or less, Twitter users have found creative ways to get the most out of each Tweet by using different communication tools. This paper looks into how 73 nonprofit organizations use Twitter to engage stakeholders not only through their tweets, but also through other various communication methods. Specifically it looks into the organizations utilization of tweet frequency, following behavior, hyperlinks, hashtags, public messages, retweets, and multimedia files. After analyzing 4655 tweets, the study found that the nation's largest nonprofits are not using Twitter to maximize stakeholder involvement. Instead, they continue to use social media as a one-way communication channel as less than 20% of their total tweets demonstrate conversations and roughly 16% demonstrate indirect connections to specific users.     

Conducting Large‐Scale Surveys in Secondary Schools: The Case of the Youth On Religion (YOR) Project

There are few published articles on conducting large‐scale surveys in secondary schools, and this paper seeks to fill this gap. Drawing on the experiences of the Youth On Religion project, it discusses the politics of gaining access to these schools and the considerations leading to the adoption and administration of an online survey. It is concluded that successful research in schools has to be planned carefully in collaboration with key members of staff, and justified as an educational activity. Providing speedy feedback was helpful to ensure schools benefited from the research and to keep them engaged with the project. © 2011 The Author(s).

基于公平关切线上与线下销售渠道演化博弈研究

公平关切影响决策行为,为分析公平关切对线上与线下销售渠道决策行为和竞争策略影响,构建线上与线下销售渠道博弈模型。基于博弈模型,对比分析四种公平关切情况对线上与线下决策变量和利润影响。进一步,为获得线上与线下稳定博弈结果,基于四种公平关切构建演化博弈模型,分析不同公平关切行为对销售渠道参与者决策行为影响。研究主要得到：一方采取公平关切时,会减少另一方收益;一方采取合作公平关切策略与另一方采取公平关切密切相关,也即当一方采取公平关切概率大于某一阀值时,另一方采取不公平关切;线上与线下经过长期演化博弈,演化稳定点为双方都采取公平关切。     

Male dominance and sexism on YouTube: results of three content analyses

This study conceptually and empirically extends a study by Wotanis and McMillan in which the authors claimed that female video producers are underrepresented on YouTube and receive much more negative (including hostile and sexist) feedback than male YouTubers. Using quantitative content analysis, this study supported the claim of female underrepresentation. Among the top 100 most subscribed YouTube channels in nine different countries (N = 900 channels), with a statistically significant proportion of only 25%, female video producers were strongly underrepresented. Additionally, a second content analysis of N = 2,400 video comments directly replicated the original study’s main quantitative results. This analysis confirmed that the popular female US comedy YouTuber Jenna Mourey (“JennaMarbles”) received much more negative (including hostile and sexist) feedback than her male counterpart Ryan Higa (“nigahiga”). However, a third content analysis of N = 6,000 video comments from five other pairs of comparable comedy YouTubers did not reveal that women’s videos generally attract a larger number of negative video comments. Possibly, women attract more negative comments only if they display their sexuality (like Jenna Mourey) or address feminist topics, but not if they conform to gender role expectations. Future research directions and practical implications are discussed.     

Distributed intervention: networked content moderation in anonymous mobile spaces

Given recent public focus on the use of digital tools to engage in discrimination and harassment, online platforms have come under increasing scrutiny to address online incivility. Many of these efforts have been critiqued for relying too heavily on technical tools or burdening individuals with the responsibility for reporting inappropriate actions. This research examines practices of digital bystander intervention on the anonymous localized mobile app Yik Yak. Through an analysis of the firsthand experiences of college students in the United States, this research identifies and investigates practices of networked intervention—that is, strategies of content moderation where success relies on collective action. Rooted in a general uncertainty and skepticism regarding reporting tools provided by the platform, findings suggest a preference for intervention practices that depend on distributed responsibility and networked activity. Taking inspiration from research on college bathroom graffiti—a parallel discursive environment—this paper employs the feminist theory of relational autonomy to explore the possibilities and limitations of networked intervention to cultivate individual and collective empowerment.     

《电子商务法》视角下网约车平台的信息披露义务

近年来网约车平台的信息管控问题受到较多关注。网约车属于服务提供型电子商务平台,具有更强的人身安全保障需求,以区别于以实物商品为交易标的的商品提供型电子商务平台。网约车平台对于服务提供过程中的驾乘信息有强大的管控能力,同时也需承担承运人责任。《电子商务法》为电子商务平台直接或间接设定了信息披露义务,在《电子商务法》未明确规定或仅做原则性规定的情形下,网约车平台亦应当根据实际情况将相应信息做单独处理以满足乘客、利益相关人和国家机关合法的信息披露要求。在一般情况下,网约车平台需向一般公众提供平台信息与平台内经营者信息,特别是法律要求的基本信息,而在特殊情况下,网约车平台不仅需要提供相应个人信息与运营信息,还需满足披露质量上的即时性和全面性要求。     

Beyond the nation-state Polish national identity and cultural intimacy online

This article analyses the debate on ‘new patriotism’ in a Polish online discussion forum. We study the ways in which national identity is constructed in this setting. Digital communication contributes further to expanding discourse on national identities beyond nation-state borders. We analyse close to 6000 posts from a large Polish Internet discussion forum through the methods of quantitative concept mapping and qualitative close readings. Our results show that patriotism is negotiated beyond strictly national frameworks. It is not merely a question of national interest as it also connects people through a process of establishing and maintaining of cultural intimacy.
