基于消费者角色感知的图书过度展露探析

针对图书消费感知第一步"展露"过程中可能出现的"过度展露"问题,尝试从选书者、读书者、买书者三个基本图书消费者角色出发加以探讨,对了解目标角色过度展露感知、客观评估调节刺激量进行研究、有利于有效传导图书价值、切实促进图书消费,亦可为如何分析把握图书营销展露刺激方向和程度厘清可行的思考路径.     

数字环境下出版企业4R营销策略研究

面对纷繁海量的媒介内容,受众与媒介作为注意力交换两大主体相互影响,相互作用的过程中,围绕数字化战略平台的4R营销理念:消费者的数字化画像与识别(recognize)、数字化信息覆盖到达(reach)、建立持续关系(relationship)、实现交易与回报(return),出版业与受众互动甚至"互构"增加出版物的社交属性,不断提升的消费者价值是出版业融合与实践的驱动力.     

Four pitfalls in normalizing citation indicators: An investigation of ESI’s selection of highly cited papers

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal.     

Proximal advantage in knowledge diffusion: The time dimension

This paper intends to explore the impact of geographic proximity on the diffusion of knowledge in the form of publication citations, and argues that codified knowledge is transmitted faster in proximity and is subject to similar geographic constraints as tacit knowledge. The geographic proximity advantage would be particularly relevant in the early stage of dissemination. We collected three sets of research articles published in 1990, 2000 and 2010 and compared the longitudinal citations they received domestically and from abroad. The study found that domestic citations accumulate faster and reach their peak much earlier than foreign citations, and the difference is most evident in the first few years after publication. The result shows that geographic proximity does play a role in the speed of knowledge diffusion and points to the network effect for citations. Those located closer to the knowledge origin would be exposed and react to publications faster due to the additional opportunities of research exchange and network.
