This article reports on a large‐scale international survey of authors' perception and experience of the journals system conducted by ciber in association with National Opinion Polls (NOP). It explores the factors that inform authors' decisions where to publish and, in particular, which groups of readers they perceive to be most important. It probes readership behaviour and the values that underlie authors' attitudes towards copyright and emerging business models, notably open access. It is concluded that many aspects of author behaviour are highly conservative and that a significant shift towards open access is, in the short to medium term, highly unlikely. 相似文献

Modelling is a concept fundamental for software engineering. In this paper, the word is defined and discussed from various perspectives. The most important types of models are presented, and examples are given. Models are very useful, but sometimes also dangerous, in particular to those who use them unconsciously. Such problems are shown. Finally, the role of models in software engineering research is discussed. 相似文献

This paper examines the relationship between the aesthetic thought of Joseph Addison and Richard Steele and early modern virtuoso culture. It argues that both Addison and Steele did not reject virtuoso culture so much as to attempt to reform and redefine it. It is observed that Addison in particular wrote a virtuoso travel narrative in his Remarks on Italy as well as contributing to the discourse on antiquarian medal-collecting. In their writings on art and connoisseurship in the Tatler and Spectator essays, both Addison and Steele can be understood as defenders of a neo-classical aesthetic that rejected and ridiculed a supposedly indiscriminate virtuoso aesthetic of curiosity. But the essays are best understood as part of an important moment of transition in which an early enlightenment notion of taste emerged from a template established by baroque virtuosity rather than as a complete rejection of virtuoso culture. 相似文献

In many probabilistic modeling approaches to Information Retrieval we are interested in estimating how well a document model
“fits” the user’s information need (query model). On the other hand in statistics, goodness of fit tests are well established
techniques for assessing the assumptions about the underlying distribution of a data set. Supposing that the query terms are
randomly distributed in the various documents of the collection, we actually want to know whether the occurrences of the query
terms are more frequently distributed by chance in a particular document. This can be quantified by the so-called goodness
of fit tests. In this paper, we present a new document ranking technique based on Chi-square goodness of fit tests. Given
the null hypothesis that there is no association between the query terms q and the document d irrespective of any chance occurrences, we perform a Chi-square goodness of fit test for assessing this hypothesis and calculate
the corresponding Chi-square values. Our retrieval formula is based on ranking the documents in the collection according to
these calculated Chi-square values. The method was evaluated over the entire test collection of TREC data, on disks 4 and
5, using the topics of TREC-7 and TREC-8 (50 topics each) conferences. It performs well, outperforming steadily the classical
OKAPI term frequency weighting formula but below that of KL-Divergence from language modeling approach. Despite this, we believe
that the technique is an important non-parametric way of thinking of retrieval, offering the possibility to try simple alternative
retrieval formulas within goodness-of-fit statistical tests’ framework, modeling the data in various ways estimating or assigning any arbitrary theoretical distribution
in terms. 相似文献

The Global Information Locator Service (GILS) encompasses a global vision framed by the fundamental values of open societies. Societal values such as a free flow of information impose certain requirements on the society’s information infrastructure. These requirements in turn shape the various laws, policies, standards, and technologies that determine the infrastructure design. A particular focus of GILS is the requirement to provide the means for people to discover sources of data and information. Information discovery in the GILS vision is designed to be decentralized yet coherent, and globally comprehensive yet useful for detailed data. This article introduces basic concepts and design issues, with emphasis on the techniques by which GILS supports interoperability. It explains the practical implications of GILS for the common roles of organizations involved in handling information, from content provider through system engineer and intermediary to searcher. The article provides examples of GILS initiatives in various types of communities: bibliographic, geographic, environmental, and government. 相似文献

The need to adapt behaviors appropriately to situational constraints and particular members is one aspect of leadership that has received minimal attention from previous research. This study examined the distributional structures of leaders' comments in discussions with differing purposes in an attempt to determine whether leaders adapt their oral behaviors to meet varying goals and to compensate for failures in previous meetings. It was concluded that leaders do adapt oral behaviors to achieve objectives and in response to past failures. This finding suggests that a broad repertoire of possible behaviors is important for successful leaders who find themselves in a variety of discussional situations with divergent goals, members, and constraints. 相似文献

Abstract Well-chosen keywords in titles are significant in enabling optimal document retrieval. Title keyword searches employing the natural language of the researcher augment controlled vocabulary searches. Authors and researchers interested in a particular topic share a vocabulary that contains keywords useful in database searching. It is important for authors to incorporate such keywords in their titles. Both author and researcher will benefit if titles facilitate electronic access. Librarians can assist in educating authors on the benefits of using distinctive and selective keywords in titles by making guidelines available. 相似文献

This article discusses the role of the online audience community as a strategic resource for media work. It opens up a current perspective on the audience community, which has received scarce attention in research both conceptually and empirically. The article provides an empirical analysis of the various ways in which the audience community can serve as a resource in the work of journalists. The conclusion is that the audience community can have wide-ranging strategic significance and implications for media work and media brands. In particular, observing and connecting with the audience community can help journalists acquire deeper knowledge and understanding of the audience, as well as strengthen commitment and engagement among the audience with the media brand. As a consequence of collaborating with the audience community, new journalistic roles and tasks are emerging. 相似文献
