数字经济下虚拟集聚的现实基础与应用

虚拟集聚是数字经济的产业组织形态,是数字经济下资源重新配置的方式,已经渗入人们经济生活的各个方面,从集聚效应、新动能、新认识、新增长点等维度剖析虚拟集聚的现实基础,研究虚拟集聚对制造业的冲击及其在数字经济下的新应用。研究认为,网络空间的虚拟集聚是以“网”为基础、以“台”为依托、以“云”为支撑、以“端”为条件,虚拟集聚是集聚在数字经济下的演进,是在网络空间的集聚,具有智能物流、交易费用、空间范围、信息匹配、知识溢出、弱化黑洞、资源配置等集聚效应; 新一轮科技革命、产业变革与中国制造强国梦形成历史性交汇,促使虚拟集聚应运而生,并且成为新一代信息技术与制造业深度融合的新动能,能够显著促进产业数字化和数字产业化,带动传统产业集群转型升级,培育出世界级的先进制造业集群,推动中国制造迈向全球产业链价值链顶端; 虚拟集聚下制造业的关键核心是互联,在应用中需要产业数字化和数字产业化相辅相成,需要技术的支撑,表现为高度自动化、高度信息化和高度网络化,横向集成、纵向集成与端到端的集成,虚拟集聚的生产要素和生产力都是在虚拟空间体现,将推动制造业数字化转型、网络化协调、智能化变革; 随着新冠肺炎疫情全球蔓延,虚拟集聚成为新经济增长点,国际供应链中的虚拟集聚显著增长,跨境电商兴起,外贸行业快速数字化发展,教育行业、学术会议借助网络和软件线上进行,线上办公、云端会展快速流行,网络与快递业、餐饮与外卖业、短视频与直播经济、云医疗与大健康迅猛发展,数字阅读、文娱产业线上流行成为新的生活方式,元宇宙的虚拟世界也将推动科技发展带来经济新增长点。     

数字普惠金融与农户相对贫困脆弱性*

测度不同贫困线标准下数字普惠金融对农户相对贫困脆弱性的作用效果及其最优指数区间,揭示数字普惠金融对不同农户相对贫困脆弱性影响的结构性差异和作用机制。研究发现:数字普惠金融对农户相对贫困脆弱性的影响既存在"数字红利"效应也存在"数字鸿沟"效应,二者呈现出倒"U"型关系,降低农户相对贫困脆弱性的最优数字普惠金融指数区间位于108~160之间。分结构看,较低贫困线标准下数字金融覆盖广度对农户相对贫困脆弱性的减缓程度更加明显,但较高贫困线标准下数字金融使用深度对农户相对贫困脆弱性的减缓程度更大,且呈小幅递增趋势。在作用机制层面,数字普惠金融主要通过提高农户数字技能和风险管理能力,降低居民收入差距来发挥中介作用,减缓农户相对贫困脆弱性。

多重网络中的词学研究

近20年来,词学研究有所进展,但仍存在一些问题。词学研究应在多重网络中展开。首先,词学是专门之学,但研究者仍需建构开放的知识网络。词乐研究虽有不少成果,但仍处于相对低潮。这与研究者受限于音乐知识,无法有效介入有关。词谱、词律等专门之学亦是如此。其次,可以尝试词学研究的时空延展,打造通观的“全息网络”,通过长时段的、大量的文本分析发现新话题。同时,注意域外汉籍,因为它们可以提供新文献,启发新视角,丰富文本网络。最后,要注意数字人文的发展趋向,要建设词学检索库,善用新技术,更新研究理念,以便及时因应。但数字人文终究只是辅助研究手段,技术取代不了阅读与思考,只有在传统研究的基础上,技术才能发挥更大的作用。     

农村电商人才胜任力模型构建——以川陕地区为例

数字经济时代,电商促进了区域经济协调发展,人才为缩小数字鸿沟提供了智力支持。运用文献研究法、行为事件访谈法提取农村电商人才胜任力模型要素,对川陕地区农村电商示范县中的电商从业者进行了调研,并通过探索性因子分析及验证性因子分析进行模型检验,构建了农村电商人才胜任力模型。模型包括外显的经营能力、基础能力、从业知识3个维度,以及内隐的职业素养、个人品质2个维度。基于农村电商人才胜任力模型,从培养机制、培训体系、绩效考核体系以及薪酬管理体系4个方面为农村电商人才培养提出相应建议。     

Curating the Soul: Foucault's concept of hupomnemata and the digital technology of self-care

This paper explores how online actions such as the practice of digital self-writing shape our offline identity. We start with an examination of the concept of hupomnemata – a practice of self-writing in which notes are kept as a ‘material record of things read, heard, or thought’ in the intent of shaping the self [Foucault (1997). Self writing. In P. Rabinow (Ed.), Ethics, subjectivity and truth. The essential works of Foucault, 1954–1984. Volume 1 (pp. 207–222). New York, NY: The New Press p. 209] – before arguing that the practice of digital content curation can be understood as a modern-day variant of the Greco-Roman hupomnemata. Although the work of the digital curator is conducted online, this paper positions contemporary curatorial practices as acts of self-exploration, self-cultivation, and self-care, which nourish offline identity and which ultimately work to shape the offline, corporeal self.     

(Un)ethical practices: intimacy and Internet in the media coverage of the Ashley Madison hack

In the summer of 2015, the “cheating website” known as Ashley Madison came under scrutiny, as a group calling itself the Impact Team revealed users’ private information. This case study explores the controversy’s Canadian media coverage and sheds light on the main discourses about intimacy and the Internet that were made visible during this event. It interrogates how cheaters, hackers, and the company were represented. To varying degrees, the mainstream press condemns the cheaters, the hackers, and the company for their behaviour. The article also addresses the ways intimate practices are politicized and commercialized in the digital context, including a discussion of the emphasis on “privacy.” To conclude the article, I discuss the transparency and privacy issues implicated in digital intimacies and the power–knowledge (im)balance implied by hackers’ online anonymity.

Pierre Bourdieu: theorizing the digital

ABSTRACT

Pierre Bourdieu is known for his research in the areas of education and cultural stratification that led to a number of theoretical contributions informing the social sciences. Bourdieu’s interrelated concepts of field, capital, and habitus have become central in many approaches to inequality and stratification across the social sciences. In addition, we argue that Bourdieu’s ideas also feature in what is increasingly known as ‘digital sociology.’ To underscore this claim, we explore the ways in which Bourdieu’s ideas continue to have a major impact on social science research both on and with digital and Internet-based technologies. To do so, we offer a review of both Bourdieusian theorizing of the digital vis-à-vis both research on the social impacts of digital communication technologies and the application of digital technologies to social science research methods. We contend that three interconnected features of Bourdieu’s sociology have allowed his approach to flourish in the digital age: (1) his theories’ inseparability from the practice of empirical research; (2) his ontological stance combining realism and social constructionism; and (3) his familiarity with concepts developed in other disciplines and participation in interdisciplinary collaborative projects. We not only reason that these three factors go some way in accounting for Bourdieu’s influence in many sociological subfields, but we also suggest that they have been especially successful in positioning Bourdieusian sociology to take advantage of opportunities associated with digital communication technologies.
