This paper investigates the situations where there are incentives for people to pay a premium over the channel costs for information content. It concludes that there are at least four: premium low relative to channel costs and monopoly, which are less interesting as they are not specific to information; where the information need is idiosyncratic; and where the quality of the information source is critical.  相似文献

Urban legends are a genre of modern folklore, consisting of stories about rare and exceptional events, just plausible enough to be believed, which tend to propagate inexorably across communities. In our view, while urban legends represent a form of “sticky” deceptive text, they are marked by a tension between the credible and incredible. They should be credible like a news article and incredible like a fairy tale to go viral. In particular we will focus on the idea that urban legends should mimic the details of news (who, where, when) to be credible, while they should be emotional and readable like a fairy tale to be catchy and memorable. Using NLP tools we will provide a quantitative analysis of these prototypical characteristics. We also lay out some machine learning experiments showing that it is possible to recognize an urban legend using just these simple features.  相似文献

During the last decade games have arguably become the largest form of leisure information systems (IS). However, today games are also increasingly being employed for a variety of instrumental purposes. Although games have garnered a substantial amount of research attention during the last decade, research literature is scattered and there is still a lack of a clear and reliable understanding of why games are being used, and how they are placed in the established utilitarian-hedonic continuum of information systems. To address this gap, we conducted a meta-analysis of the quantitative body of literature that has examined the reasons for using games (48 studies). Additionally, we compared the findings across games that are intended for either leisure or instrumental use. Even though games are generally regarded as a pinnacle form of hedonically-oriented ISs, our results show that enjoyment and usefulness are equally important determinants for using them (though their definitive role varies between game types). Therefore, it can be posited that games are multi-purpose ISs which nevertheless rely on hedonic factors, even in the pursuit of instrumental outcomes. The present study contributes to and advances our theoretical and empirical understanding of multi-purpose ISs and the ways in which they are used.  相似文献

The stereotypical scientist wears a lab-coat, is often eccentric and is usually male. Images of female scientists in popular culture remain rare. Some of the first portrayals of women in science occurred in a handful of British films made during the 1950s and 1960s. These films reflected the difficulties experienced by women in science at the time, but they might also explain why representations of female scientists in film continue to downplay their role as scientists and emphasize their identity as women.  相似文献

Self-plagiarism is a controversial issue in scientific writing and presentation of research data. Unlike plagiarism, self-plagiarism is difficult to interpret as intellectual theft under the justification that one cannot steal from oneself. However, academics are concerned, as self-plagiarized papers mislead readers, do not contribute to science, and bring undeserved credit to authors. As such, it should be considered a form of scientific misconduct. In this paper, we explain different forms of self-plagiarism in scientific writing and then present good editorial policy toward questionable material. The importance of dealing with self-plagiarism is emphasized by the recently published proposal of Text Recycling Guidelines by the Committee on Publication Ethics (COPE).  相似文献

Many researchers have pointed out that the open source movement is an interesting phenomenon that is difficult to explain with conventional economic theories. However, while there is no shortage on research on individuals’ motivation for contributing to open source, few have investigated the commercial companies’ motivations for doing the same. A case study was conducted at three different companies from the IT service industry, to investigate three possible drivers: sale of complimentary services, innovation and opensourcing (outsourcing). We offer three conclusions.  相似文献

In producing news stories, journalists depend on information obtained from sources. This paper reviews the literature on journalists’ information seeking. The 90 studies included in the review cover how journalists identify sources, interact with sources, interpret information, and manage sources. In addition to quality and accessibility, balance in the group of sources selected is an important criterion in journalists’ identification of sources. However, the importance journalists assign to balance stands in contrast to the frequent finding of bias in their source selections. In interactions with sources, the sources frequently provide ideas for new stories in addition to information for current ones. This finding shows how multiple instances of information seeking coexist and combine into a mesh of intersecting information-seeking processes. In interpreting information, journalists are acutely aware that sources may have an agenda or be misinformed. While journalists praise information checking, they regularly bypass it or replace direct checks for information quality with indirect checks, such as whether the source appears trustworthy. In managing sources, journalists engage in boundary work to regulate their relationship with sources. They also cultivate long-term relationships with selected sources. The review findings are discussed with respect to how journalism shapes journalists’ information seeking and what implications the findings have for information-behavior research in other domains.  相似文献

The aim of this essay is to discuss the relation between experimenter and instruments in terms of how they interact: how the instrument requires a particular performance from the experimenter, how the experimenter requires a particular performance from the instrument, how a particular purpose of the experimental procedures requires a particular performance from the experimenter and the instrument, and, finally, how both-experimenter and instrument in their interplay-are subject to standards that can be related to social, political, or epistemological criteria. The author draws on his own experiences in analyzing experiments using the replication method.  相似文献

This paper analyses how and why different types of innovation systems interact through analysing seven Australian sectors. We find that there are sets of mechanisms or systems that ‘articulate’; i.e. structure and shape the interaction among sectoral innovation systems and other types of innovation systems. Drawing on the Schumpeterian and evolutionary legacy, we contribute a theoretical explanation of how interaction among innovation systems influences innovation. First, this interaction enables and enhances variety creation by expanding the new combinations of knowledge and resources a firm can achieve. Second, it allows for more efficient and effective scaling up of useful knowledge recombination to achieve increasing returns. Empirically, this is supported in that the more successful sectors have active articulation systems with alignment with other systems, while weaker sectors have unplanned and patchy linkages. No simple model seems to explain successful articulation. However, important factors are active receptor firms with the motivation and capabilities to absorb and use resources from external systems, high quality and responsive education systems, and international linkages. Public research, labour markets, and intermediaries varied in importance.  相似文献

Digital entrepreneurship is one of the most important and impactful forms of entrepreneurship. However, the majority of digital start-ups fail to scale, despite their potential to achieve growth. Moreover, what constitutes growth is significantly different for start-ups as compared with established firms: they have limited financial performance, and their growth cannot be accurately measured by metrics such as customers, revenues, profits, and turnover at the early stages of the new venture creation process or before the start-up has reached sustainability. Therefore, the first objective of this research is to contribute to the definition of growth by examining less tangible dimensions of growth. Moreover, the second objective is to identify the characteristics of early-stage digital start-ups experiencing growth. Based on a mixed-methods approach, which combines an adapted Delphi study, a questionnaire-based survey, and a comparative case study, our results suggest that growing digital start-ups exhibit a set of characteristics that include: an agile culture combining clan with adhocracy; the ability to nurture their absorptive, innovative, and adaptive capabilities effectively; and a human capital with adequate entrepreneurial skills, emotional attachment to and fitness with the start-up.  相似文献

In the innovation process of firms, suppliers increasingly play a key role as external sources of ideas. Although the beneficial impact of supplier integration has been acknowledged, there is also evidence that not all such innovation efforts are successful, particularly regarding the identification of truly innovative solutions. Therefore, in recent years, large firms have begun to move beyond their existing supply base, drawing on innovation ideas from start-ups, that is, with young firms with whom they have no pre-existing bonds. Yet there is no empirical evidence regarding whether start-ups’ ideas actually outperform those of established suppliers. We address this question by presenting a unique, real-world comparison of 314 supplier and start-up ideas – ideas that were identified, evaluated, and followed up over the course of an open innovation initiative conducted by a large automotive manufacturer. We find that start-ups’ ideas are characterized by a higher degree of novelty and to some extent higher benefit for end customers but, on the downside, are less likely to be implemented than suppliers’ ideas. Overall, our study adds new dimensions to the discourse on open innovation and provides valuable insights regarding the outcome of supplier and start-up involvement in the front end of the innovation process.  相似文献

There is an increasing recognition that various stakeholder groups for e-government have a significant role to play in ensuring the long-term success of the e-government enterprise. This article seeks to contribute to the understanding of the stakeholders’ multiple perspectives by proposing typologies of stakeholder roles, and stakeholder benefits, respectively, and embedding these in a stakeholder benefits analysis tool. A literature review is used to surface the diverse existing categorizations of e-government stakeholders and their interests and the benefits sought. This review informs a proposal for a typology of stakeholder roles, and for a typology of stakeholder benefits, which together are used to construct an initial proposal for a stakeholder benefits analysis tool (SBAT), which can be used to map stakeholder roles to stakeholder benefits. This tool has been tested by an expert group, and revised. This exploratory study is an important first step towards the development of tools and approaches for understanding the benefits sought by a wide range of different stakeholder groups in e-government. Progress in the development of such tools is important for the development of knowledge and practice, policy, and evaluation with respect to stakeholder engagement with, and participation in, e-government.  相似文献

In this paper, we address the question of ‘Why do firms publish scientific papers?’. Research examining the competitive advantages that firms accrue from investment in R&D has provided evidence that such efforts can be associated with the voluntary disclosure of research findings in scientific publications. This form of scientific openness occurs despite potentially undermining the value-capturing process by generating knowledge spillovers and hindering the use of other instruments for protecting intellectual property (patents and secrecy). Our understanding of what leads firms to engage in scientific publishing remains relatively limited, however. We address this gap by presenting a systematic review of 164 studies examining firm publishing. We then develop a conceptual framework that outlines five incentives for firms to engage in publishing: (i) accessing external knowledge and resources; (ii) attracting and retaining researchers; (iii) supporting IP strategies; (iv) building the firm's reputation; and (v) supporting commercialization strategies. Mechanisms that relate incentives to publish to firms' major stakeholders – i.e. academia, industry, investors, users, and institutions – are also outlined in the framework. We conclude by setting out an agenda for future research.  相似文献

This paper examines the impact of universities on the technological performance of adjacent firms. We extend existing research by jointly analyzing, and comparing, the effects of education (graduates) and scientific research (publications) activities of universities on firms’ technological performance. Adopting the knowledge production framework, our study is conducted at the level of 101 Italian territorial areas (provinces) and four industries. Overall, fixed-effect panel data models reveal a positive effect of both university graduates and scientific publications on the technological performance of firms. At the same time, considerable industry differences are observed. While the provision of university graduates positively affects firm performance in all industries under study, additional effects for scientific research are only observed in electrical and pharmaceutical industries that are science-intensive and where the scientific knowledge base is changing rapidly over time. The observation that spillovers from academia into the industrial texture of provinces rely on education and research in an industry-specific manner is relevant to the design of appropriate research and innovation policies.  相似文献

The emergence of social media has fundamentally changed the way of scholarly communication and allows for scientific research to be shared at an unprecedented speed and scale. While many studies have discussed what papers attract most online attention, how they prevail online is unclear. In this paper, we explore the diffusion patterns of ~170,000 papers with different journal tiers from 2012 to 2019 based on over 3 million Twitter mentions. We first categorize journals by the elite (the top of Q1) and non-elite (Q2~Q4) according to their journal impact factor quartiles, then use network analysis and time series analysis to characterize papers’ dynamic diffusion process, and finally discuss papers’ engaged users and disciplinary contexts. Results show that though elite journal papers spread significantly faster and more broadly than non-elite, some non-elite journal papers reached a sizable audience. For non-elite journal papers, a decent size of social media reach can be achieved through the aid of highly influential users or multiple waves of small spread that span a long period. As a result, popular non-elite journal papers tend to be more viral than the elite, focusing discussions around topics close to daily life. This study provides a new perspective to characterize the diffusion process of scientific papers and helps to further enhance the understanding of such a process.  相似文献

Although R&D spillovers play a key role in the battle for technological leadership, it is unclear under what conditions firms build on and benefit from the discoveries of others. The study described here empirically examines this issue. The findings indicate that, depending on technological opportunities, firm size and competitive pressure, the net impact of R&D spillovers on productivity can be either positive or negative. Specifically, we find that although spillover effects are positively associated with the technological opportunities that a firm faces, this relationship is reversed when firm size is considered. Whilst external R&D affects large self-reliant firms negatively, its impact on the productivity of smaller firms (who usually introduce incremental innovations that are characterized by a strong reliance on external technologies) is positive, and even higher than that of their own R&D. We also demonstrate that the economic payoff for firms’ own R&D is lower when they face intense competition. In cases of low-appropriability, however, spillover effects are more positive, allowing firms to increase their performance using the inventions of others.  相似文献
