The economic and social gains from electronic commerce (e-commerce) that promote innovation, industry upgrading and economic growth have been widely discussed. China’s successful experience with e-commerce has had a positive effect in transforming consumer-goods sectors of the economy and motivating economic reform. This article looks at how e-commerce reduces barriers to entry and enables firms to move up the value chain by using the global value chain framework to analyse the impact of e-commerce on the upgrading trajectories and governance structures of China’s apparel industry. For large Chinese brands, e-commerce has enabled end-market diversification. For small- and medium-sized enterprises, e-commerce has facilitated entry with functional upgrading as well as end-market upgrading. In the “two-sided markets” created by platform companies, the “engaged consumers” are the demand side of this market, and “e-commerce focused apparel firms” are the supply side of the new market. Consumers and platforms are more directly involved in value creation within this emerging internet-based structure. 相似文献

One of the most exciting developments in Canadian federalism has been the emergence of Aboriginal self-governing regions. This paper constructs a theoretical framework for exploring the evolution of intra-jurisdictional relations in the self-governing Inuit regions of the Canadian Arctic. Intra-jurisdictional relations in these regions are characterized by a unique set of relationships between elected governments and organizations that represent the beneficiaries of land-claims agreements. Using the literature on historical institutionalism, we argue that the nature of Inuit intra-jurisdictional relations following the establishment of self-government can be explained by the institutional choices made prior to the signing of land-claims agreements and/or self-government agreements. To illustrate the potential of our framework for analysing Inuit intra-jurisdictional relations, we briefly examine the experiences of Nunavut, an Inuit-dominated region and the newest territory in the Canadian federation. 相似文献

The (unheralded) first step in many applications of automated text analysis involves selecting keywords to choose documents from a large text corpus for further study. Although all substantive results depend on this choice, researchers usually pick keywords in ad hoc ways that are far from optimal and usually biased. Most seem to think that keyword selection is easy, since they do Google searches every day, but we demonstrate that humans perform exceedingly poorly at this basic task. We offer a better approach, one that also can help with following conversations where participants rapidly innovate language to evade authorities, seek political advantage, or express creativity; generic web searching; eDiscovery; look‐alike modeling; industry and intelligence analysis; and sentiment and topic analysis. We develop a computer‐assisted (as opposed to fully automated or human‐only) statistical approach that suggests keywords from available text without needing structured data as inputs. This framing poses the statistical problem in a new way, which leads to a widely applicable algorithm. Our specific approach is based on training classifiers, extracting information from (rather than correcting) their mistakes, and summarizing results with easy‐to‐understand Boolean search strings. We illustrate how the technique works with analyses of English texts about the Boston Marathon bombings, Chinese social media posts designed to evade censorship, and others. 相似文献

Little is known about the incidence of malingering or the diagnostic criteria for malingering employed by forensic clinical psychologists conducting pretrial evaluations for the criminal justice system. The clinical presentations of 39 criminal defendants diagnosed as malingering psychotic symptoms were contrasted with 25 defendants diagnosed as genuinely psychotic. The incidence of diagnosed malingering was 8% in a series of 314 consecutive evaluations. Malingerers differed from psychotics on 14 of 24 clinical presentation variables, including measures of general presentation, affect, hallucinations, delusions, and formal thought disorder. Results indicate consistent clinical features associated with the diagnosis of malingered psychosis.A summary of this study was presented at the 1988 Annual Convention of the American Psychological Association in Atlanta, Georgia. We very much appreciate the contribution made by the six forensic clinical psychologists at the Michigan Center for Forensic Psychiatry who volunteered to participate in this study. 相似文献
