The formulation of national research policies would benefit greatly from reliable strategic analysis of the scientific infrastructure, aimed at identifying the relevant strengths and weaknesses at field level. Bibliometric methodologies thus far proposed in the literature are not completely satisfactory. This work proposes a novel “output-to-input-oriented” approach, which permits identification of research strengths and weaknesses on the basis of the ratios of top scientists and highly cited articles to research expenditures in each field. The proposed approach is applied to the Italian academic system. 2012–2016 scientific publications are analyzed, in the 218 research fields where bibliometric assessment is appropriate.  相似文献

In this paper we present a first large-scale analysis of the relationship between Mendeley readership and citation counts with particular documents’ bibliographic characteristics. A data set of 1.3 million publications from different fields published in journals covered by the Web of Science (WoS) has been analyzed. This work reveals that document types that are often excluded from citation analysis due to their lower citation values, like editorial materials, letters, news items, or meeting abstracts, are strongly covered and saved in Mendeley, suggesting that Mendeley readership can reliably inform the analysis of these document types. Findings show that collaborative papers are frequently saved in Mendeley, which is similar to what is observed for citations. The relationship between readership and the length of titles and number of pages, however, is weaker than for the same relationship observed for citations. The analysis of different disciplines also points to different patterns in the relationship between several document characteristics, readership, and citation counts. Overall, results highlight that although disciplinary differences exist, readership counts are related to similar bibliographic characteristics as those related to citation counts, reinforcing the idea that Mendeley readership and citations capture a similar concept of impact, although they cannot be considered as equivalent indicators.  相似文献

The percentages of shares of world publications of the European Union and its member states, China, and the United States have been represented differently as a result of using different databases. An analytical variant of the Web-of-Science (of Thomson Reuters) enables us to study the dynamics in the world publication system in terms of the field-normalized top-1% and top-10% most-frequently cited publications. Comparing the EU28, USA, and China at the global level shows a top-level dynamic that is different from the analysis in terms of shares of publications: the United States remains far more productive in the top-1% of all papers; China drops out of the competition for elite status; and the EU28 increased its share among the top-cited papers from 2000 to 2010. Some of the EU28 member states overtook the United States during this decade; but a clear divide remains between EU15 (Western Europe) and the Accession Countries. Network analysis shows that China was embedded in this top-layer of internationally co-authored publications. These publications often involve more than a single European nation.  相似文献

The purpose of this study was to examine the relationship between publication rate, top journal publications and excellence during the first eight years of the career, and how well publication rate, top journal publications and highly cited publications during the first four years of the career can predict whether an author attain excellence in the fifth to the eighth year. The dataset consisted of publication track records of 406 early career mathematicians in the sub-field of number theory collected from the MathSciNet database. Logistic regression and dominance analysis was applied to the data. The major conclusions were (1) publication rate had a positive effect on excellence during the first eighth years of the career. However, those who publish many articles in top journals, which implicitly require a high publication count, had an even higher probability of attaining excellence. These results suggest that publishing in top journals is very important in the process of attaining excellence in the early career in addition to publishing many papers; and (2) a dominance analysis indicated that the number of top journal publications and highly cited publications during the first four years of the career were the most important predictors of who will attain excellence in the later career. The results are discussed in relation to indicator development and science policy.  相似文献

Using the example of microarrays, one of the constitutive technologies of post-genomic biomedicine, this paper introduces a method for analyzing publications, patents and research grants as proxies for “triple-helix interfaces” between university, industry and government activities. Our method creates bridges that allow one to move seamlessly between publication, patent and research project databases that use different fields and formats, and contain different information. These links do not require pre-defined categories in order to search for correspondences between sub-topics or research areas in the three databases. Finally, our results are not restricted to quantitative information but, rather, allow one to carry out qualitative investigations of the content of research activities. Our approach draws on a combination of text-mining and network analysis/mapping software packages.  相似文献

This article presents a bibliometric analysis of the financing of innovation during the period 2001–2016. Among the most prominent journals in the field are Research Policy, Technovation and Small Business Economics; among the most influential authors are Petersen, Hall, Himmelberg, Lerner and Brown; and the most connected documents are those by Hall (2002) and Brown, Fazzari, and Petersen (2009). The field is fragmented and uses a variety of financial theoretical models. Salient topics in the field are financial constraints, funding sources (internal and external), capital structure, venture capital and financing of technology companies.  相似文献

The Maximum Entropy Principle (MEP) maximizes the entropy provided that the effort remains constant. The Principle of Least Effort (PLE) minimizes the effort provided that the entropy remains constant. The paper investigates the relation between these two principles. In some kinds of effort functions, called admissible, it is shown that these two principles are equivalent. The results are illustrated by the size–frequency statistical distribution met in infometry in Information Production Processes.  相似文献

  • The success of the CHORUS and DOE relationship is the result of nearly two decades of interactions between the DOE and a group of scientific publishers.
  • The relationship between CHORUS and the US federal agencies required understanding of different motivations, operations, and philosophies.
  • Although achieving public access was simple in principle, it required considerable effort to develop systems that satisfied all parties.
  • Publishers had been working with federal agencies to achieve open access before the 2013 White House Office of Science and Technology Policy, but this helped to create a path for a more fruitful relationship.

The paper examines the state and basic directions of fundamental studies in the field of informatics, as well as the modern trends and prospects of its development as a science and complex research issue. At present, informatics is at a new stage of development and will, in the nearest future become an independent branch of science.  相似文献

The primary aim of this study was to analyze and interpret some aspects of the process of organizational identification in a corporate field setting. Specifically, the study focused on how an individual's identification (or identifying) with an employing organization influences on‐the‐job decision making. Past research efforts have been limited by their treatment of organizational identification as a product or state, rather than as a process. The wider perspective on identification is well represented by Herbert A. Simon and Kenneth Burke, whose writings were integrated to provide a theoretical framework for this study. While this study neither examined the phenomenon of identification over time nor placed it in a clearly‐defined causal chain, it explicitly recognized identification as a continuing development involving many changes. The study employed two methodologies for the examination of identification in a corporate field setting: moderately‐scheduled interviews that produced largely qualitative data and a questionnaire instrument that yielded quantitative data. The methods were “triangulated” so as to provide a more detailed “snapshot” of the identification process than either would offer alone; moreover, the “accounts” elicited in employee interviews yielded retrospectives on individual‐organization relationships. The results suggest the soundness of the theoretical framework advanced at the outset. Most employees who were interviewed saw organizational interests as directly relevant to work‐related decisions. Their comments as well as their questionnaire responses indicated that they also identified with the organization, thus offering support for the link between organizational identification and decision making.  相似文献

Competency theory predicts a miscalibration between students' self-assessments of their information literacy skills and their actual skill level. This study investigates whether such a disparity is evident among incoming freshmen who test as non-proficient on a standardized test of information literacy. In addition, this study analyzes Information Literacy Test scores and library anxiety test scores to provide preliminary data on whether library anxiety is related to information literacy skill attainment. Findings reveal that the relationship between information literacy skills and self-assessments predicted by competency theory are evident in the domain of information literacy. This study did not find an association between information literacy skill scores and total library anxiety scores. However, a significant negative correlation between information literacy scores and the subscale “knowledge of the library” indicates that as information literacy scores rise, anxiety scores related to a lack of knowledge of the library fall. The findings suggest that traditional information literacy instruction may not be effective with non-proficient students, who are unlikely to see themselves as needing or benefiting from such instruction.  相似文献

The method of bibliographic coupling in combination with the complete link cluster method was applied for mapping of the field of organic chemistry with the purpose of testing the applicability of a proposed mapping method on the field level. The method put forward aimed at the generation of cognitive cores of documents, so-called ‘bibliographic cliques’ in the network of bibliographically coupled research articles. The defining feature of these cliques is that they can be considered complete graphs where each bibliographic coupling link ties an unordered pair of documents. In this way, it was presumed that coherent groups of documents in the research front would be found and that these groups would be intellectually coherent as well. Statistical analysis and subject specialist evaluations confirmed these presumptions. The study also elaborates on the choice of observation period and the application of thresholds in relation to the size of document populations.  相似文献

Nations can be distinguished in terms of whether domestic or international research is cited. We analyzed the research output in the natural sciences of three leading European research economies (Germany, the Netherlands, and the UK) and ask where their researchers look for the knowledge that underpins their most highly-cited papers. Is one internationally oriented or is citation limited to national resources? Do the citation patterns reflect a growing differentiation between the domestic and international research enterprise? To evaluate change over time, we include natural-sciences papers published in the countries from three publication years: 2004, 2009, and 2014. The results show that articles co-authored by researchers from Germany or the Netherlands are less likely to be among the globally most highly-cited articles if they also cite “domestic” research (i.e. research authored by authors from the same country). To put this another way, less well-cited research is more likely to stand on domestic shoulders and research that becomes more highly-cited is more likely to stand on international shoulders. A possible reason for the results is that researchers “over-cite” the papers from their own country – lacking the focus on quality in citing. However, these differences between domestic and international shoulders are not visible for the UK.  相似文献

We evaluate article-level metrics along two dimensions. Firstly, we analyse metrics’ ranking bias in terms of fields and time. Secondly, we evaluate their performance based on test data that consists of (1) papers that have won high-impact awards and (2) papers that have won prizes for outstanding quality. We consider different citation impact indicators and indirect ranking algorithms in combination with various normalisation approaches (mean-based, percentile-based, co-citation-based, and post hoc rescaling). We execute all experiments on two publication databases which use different field categorisation schemes (author-chosen concept categories and categories based on papers’ semantic information).In terms of bias, we find that citation counts are always less time biased but always more field biased compared to PageRank. Furthermore, rescaling paper scores by a constant number of similarly aged papers reduces time bias more effectively compared to normalising by calendar years. We also find that percentile citation scores are less field and time biased than mean-normalised citation counts.In terms of performance, we find that time-normalised metrics identify high-impact papers better shortly after their publication compared to their non-normalised variants. However, after 7 to 10 years, the non-normalised metrics perform better. A similar trend exists for the set of high-quality papers where these performance cross-over points occur after 5 to 10 years.Lastly, we also find that personalising PageRank with papers’ citation counts reduces time bias but increases field bias. Similarly, using papers’ associated journal impact factors to personalise PageRank increases its field bias. In terms of performance, PageRank should always be personalised with papers’ citation counts and time-rescaled for citation windows smaller than 7 to 10 years.  相似文献

The role of the press as a political watchdog is crucial to the functioning of democracy. Especially in the run-up to elections, voters depend on the media's presentation of parties and candidates to make informed, responsible choices at the ballot box. But who, then, influences the news media? Empirical evidence in the United States and Europe suggests that political party campaigns and election coverage in the news media are interconnected and influence each other. This study tests whether such agenda-setting effects between party campaigns and the media also take place in the general elections in the world's largest democracy, India. India's western-type political system has a distinct media system characterized by high competition, diversification, non-consolidation and formal and informal ties between the media, commercial interests and political actors. Content analysis and Granger's causality test of newspaper coverage (N?=?716) and party campaign messages (N?=?458) found that agenda-setting effects do occur in India, but are largely bi-directional. We also found an overwhelming focus of both newspapers’ election coverage and of all major party campaigns on one single candidate, the Bharatiya Janata Party (BJP)'s Narendra Modi. This, we argue, is a result of the broader trends that have shaped Indian politics in recent years. The significant correlations and non-significant causal effects between party campaign and media coverage also indicate a trade-off situation between political power negotiation and political balance in the press.  相似文献
