In many countries the scientific funding system is shifting from an internal block funding model toward a competitive project funding model. However, there is growing concern that the competitive project funding system favors relatively safe, conventional projects at the expense of risky, novel research. It is important to assess different funding models in order to design better funding systems for science. This paper empirically tests for differences in the novelty of funded outputs between internal block funding and competitive project funding, in the setting of Japan, where both funding models play a significant role. Combining survey data from a large sample of research projects in Japan and bibliometric information about the publications produced from these projects, we find that projects funded by competitive funds on average have higher novelty compared to those funded by internal block funds. However, such positive effects only hold for researchers with high status, such as senior and male researchers. In contrast, compared to internal block funding, competitive project funding has a negative relation to novelty for low status scientists (especially junior and female researchers). The findings suggest that the competitive project selection procedure is less receptive to novel ideas from researchers with low academic status and therefore discourages their novel research. These findings can serve as a warning about potential biases in competitive funding allocation procedures and suggest the importance of secure stable funding for allowing researchers with low status to pursue their novel ideas.  相似文献

Scientists continually work with information to move their research projects forward, but the activities involved in finding and using information and their impact on discovery are poorly understood. In the Information and Discovery in Neuroscience (IDN) project we investigated the information work involved as researchers make progress and confront problems in the practice of brain research. Through case studies of recent neuroscience projects, we found that the most difficult and time-consuming information activities had parallels with Simon’s explication of weak methods in scientific problem solving. But, while Simon’s weak/strong distinction is an effective device for interpreting information work, his general conception of how discovery takes place is artificially constrained. We present cross-case and case-based results from the IDN project to illustrate how the conditions of problem solving Simon associated with weak methods relate to information work and to identify additional weak aspects of the research process not considered by Simon. Our analysis both extends Simon’s framework of what constitutes the discovery process and further elaborates how weak approaches influence the conduct of research.  相似文献

Nowadays we use information retrieval systems and services as part of our many day-to-day activities ranging from a web and database search to searching for various digital libraries, audio and video collections/services, and so on. However, IR systems and services make extensive use of ICT (information and communication technologies) and increasing use of ICT can significantly increase greenhouse gas (GHG, a term used to denote emission of harmful gases in the atmosphere) emissions. Sustainable development, and more importantly environmental sustainability, has become a major area of concern of various national and international bodies and as a result various initiatives and measures are being proposed for reducing the environmental impact of industries, businesses, governments and institutions. Research also shows that appropriate use of ICT can reduce the overall GHG emissions of a business, product or service. Green IT and cloud computing can play a key role in reducing the environmental impact of ICT. This paper proposes the concept of Green IR systems and services that can play a key role in reducing the overall environmental impact of various ICT-based services in education and research, business, government, etc., that are increasingly being reliant on access and use of digital information. However, to date there has not been any systematic research towards building Green IR systems and services. This paper points out the major challenges in building Green IR systems and services, and two different methods are proposed for estimating the energy consumption, and the corresponding GHG emissions, of an IR system or service. This paper also proposes the four key enablers of a Green IR viz. Standardize, Share, Reuse and Green behavior. Further research required to achieve these for building Green IR systems and services are also mentioned.  相似文献

With the advancement of mobile technologies, numerous web service providers have begun to extend their web services to the mobile context. To understand users’ mobile service adoption behaviour in the context of the web–mobile service transition, this study investigates the role of consistency between web and mobile services by proposing a typology of consistency and examining the extent to which and the boundary conditions under which consistency works. Specifically, consistency is classified into behavioural consistency (e.g., operational consistency) and object-based consistency, which includes consistency in information, system and service in terms of the information systems success model. We also contend the mediating effect of operational consistency and the interaction effect of trust in web services and operational consistency. A field survey with 235 mobile service users confirms our mediating and moderating hypotheses. The implications for theory and practice are also discussed.  相似文献

信息传播有利于风险投资克服信息不对称性和项目不确定性等关键问题,对风险投资网络社群具有重要意义。利用2000至2015年CVsource数据库中风险投资数据,本文研究风险投资网络社群信息传播对投资绩效的影响及其机理。研究发现,风险投资网络社群信息传播对投资绩效有显著影响,具体表现为项目信息传播对投资绩效呈先增后减的倒U型影响,经验信息传播对投资绩效呈显著正向影响。知识获取分别在项目信息传播和经验信息传播与投资绩效的关系中具有部分中介作用。另外,吸收能力显著负向调节知识获取对投资绩效的正向影响。上述结果意味着,信息传播不仅可以直接作用于投资绩效,而且可以通过知识获取及吸收能力对投资绩效产生间接作用。利用一个社会网络的分析框架,本文论证了信息传播对风险投资绩效的影响机理,并且为风险投资网络社群行为优化以及投资绩效提升提供了经验证据。  相似文献

Information management is the management of organizational processes, technologies, and people which collectively create, acquire, integrate, organize, process, store, disseminate, access, and dispose of the information. Information management is a vast, multi-disciplinary domain that syndicates various subdomains and perfectly intermingles with other domains. This study aims to provide a comprehensive overview of the information management domain from 1970 to 2019. Drawing upon the methodology from statistical text analysis research, this study summarizes the evolution of knowledge in this domain by examining the publication trends as per authors, institutions, countries, etc. Further, this study proposes a probabilistic generative model based on structural topic modeling to understand and extract the latent themes from the research articles related to information management. Furthermore, this study graphically visualizes the variations in the topic prevalences over the period of 1970 to 2019. The results highlight that the most common themes are data management, knowledge management, environmental management, project management, service management, and mobile and web management. The findings also identify themes such as knowledge management, environmental management, project management, and social communication as academic hotspots for future research.  相似文献
