    Field normalized citation rates, field normalized journal impact and Norwegian weights for allocation of university research funds2012In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 92, no 2, p. 767-780Article in journal (Refereed)
    Abstract [en]

    We compared three different bibliometric evaluation approaches: two citationbased approaches and one based on manual classification of publishing channels into quality levels. Publication data for two universities was used, and we worked with two levels of analysis: article and department. For the article level, we investigated the predictive power of field normalized citation rates and field normalized journal impact with respect to journal level. The results for the article level show that evaluation of journals based on citation impact correlate rather well with manual classification of journals into quality levels. However, the prediction from field normalized citation rates to journal level was only marginally better than random guessing. At the department level, we studied three different indicators in the context of research fund allocation within universities and the extent to which the three indicators produce different distributions of research funds. It turned out that the three distributions of relative indicator values were very similar, which in turn yields that the corresponding distributions of hypothetical research funds would be very similar.

    Bibliometric analysis of two subdomains in philosophy: free will and sorites2015In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 103, no 1, p. 47-73Article in journal (Refereed)
    Abstract [en]

    In this study we tested the fruitfulness of advanced bibliometric methods for mapping subdomains in philosophy. The development of the number of publications on free will and sorites, the two subdomains treated in the study, over time was studied. We applied the cocitation approach to map the most cited publications, authors and journals, and we mapped frequently occurring terms, using a term co-occurrence approach. Both subdomains show a strong increase of publications in Web of Science. When we decomposed the publications by faculty, we could see an increase of free will publications also in social sciences, medicine and natural sciences. The multidisciplinary character of free will research was reflected in the cocitation analysis and in the term co-occurrence analysis: we found clusters/groups of cocited publications, authors and journals, and of co-occurring terms, representing philosophy as well as non-philosophical fields, such as neuroscience and physics. The corresponding analyses of sorites publications displayed a structure consisting of research themes rather than fields. All in all, both philosophers involved in this study acknowledge the validity of the various networks presented. Bibliometric mapping appears to provide an interesting tool for describing the cognitive orientation of a research field, not only in the natural and life sciences but also in philosophy, which this study shows.

    Globalization of citations and collaboration: a study of twelve journals2012In: Proceedings of 17th International Conference on Science and Technology Indicators / [ed] Éric Archambault, Yves Gingras and Vincent Larivière, 2012, p. 23-32Conference paper (Refereed)
    Abstract [en]

    We treated citations and collaboration from a spatial point of view with respect to twelve journals. Eleven of the journals are from the field of information science, the remaining one from the nanotechnology field. Publication data from Web of Science were used. The twelve journals were compared with respect to mean global impact (in terms of geographical citation distance), citation impact, share of foreign country citation links, degree of concentration of country citation links, and mean geographical collaboration distance. The information science journals oriented towards research evaluation tended to have lower global impact than the more general information science journals, whereas a reversed pattern was observed regarding share of foreign country citation links. For the relation between global impact and citation impact, there was a weak similarity between the global impact ordering and the citation impact ordering of the journals. Regarding the degree of concentration of country citation links, the links were found to be highly concentrated to certain countries, irrespective of if cited or citing countries were considered. For geographical collaboration distance, the nanotechnology journal in the study, Nature Nanotechnology, had the highest indicator value, which is in agreement with the outcome for global impact.

    Geographical distance in bibliometric relations within epistemic communities2013In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 95, no 2, p. 771-784Article in journal (Refereed)
    Abstract [en]

    Scientists collaborate increasingly on a global scale. Does this trend also hold for other bibliometric relations such as direct citations, cocitations and shared references? This study examines citation-based relations in publications published in the journal Scientometrics from 1981 to 2010. Different measures of Mean Geographical Distance (MGD) are tested. If we take all citation links into consideration, there is no indication of MGD increase, but when we look at maximum distances of each relation, a weak tendency of increasing MGD could be observed. One major factor behind the lack of growth of mean distances is the form of the distribution of citation links over distances. Our data suggest that the interactions might grow simultaneously for both short and long distances.

    The Sutherland tradition in criminology: a bibliometric story2013In: Criminal justice studies, ISSN 1478-601X, E-ISSN 1478-6028, Vol. 26, no 1, p. 1-18Article in journal (Refereed)
    Abstract [en]

    In this article, we provide an overview of the body of knowledge associated with the Sutherland tradition in criminology. We track Sutherland's impact through a bibliometric analysis of papers citing any of Sutherland's works and by focusing on publications that are co-cited with Sutherland. This approach enables us to visualize Sutherland's role in relation to the forerunners and founding fathers of criminology during his own active period, to his followers, and to contemporary scholars. The dataset consisted of 2596 genuine articles that cite at least one of Sutherland's publications, in which he appears as first author in Web of Science TM published between 1955 and 2010. The results show a clear impact of the Sutherland tradition more or less throughout the twentieth century, peaking during the 1930s and 1940s and decreasing in the 1990s, when the Sutherland tradition was more powerfully challenged, primarily by the life-course tradition.

    Country comparisons of human stroke research since 2001: a bibliometric study2012In: Stroke, ISSN 0039-2499, E-ISSN 1524-4628, Vol. 43, no 3, p. 830-837Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND PURPOSE: This is the first bibliometric comparison between countries of the development of stroke research over time.

    METHODS: Clinical and epidemiological articles on stroke published 2001 to mid-2011 were identified in Science Citation Index Expanded. Article fractions, citation fractions, h-index, and international collaboration were calculated using the BibExcel software and adjusted for population size and gross domestic product.

    RESULTS: The United States dominated with 28.7% of the sum of article fractions and 36.2% of the sum of citation fractions. The United States, Japan, the United Kingdom, and Germany together accounted for 52.1% of articles and 61.0% of citations. When adjusted for population size or gross domestic product, several small European countries, together with Israel and Taiwan, ranked the highest. Per population, there was a negative association (r=0.60) between burden of stroke (disability-adjusted life-years lost) and number of articles per population. In China, South Korea, and Singapore, the annual growth of stroke articles was more than twice the worldwide average. Whereas multinational collaboration was common within Europe and North America, it was relatively uncommon between Asian countries.

    CONCLUSIONS: The Big 4 in scientific literature on stroke, as to both number of articles and citations, are the United States, Japan, the United Kingdom, and Germany. Many small European countries have, in relation to their size, a high scientific production. Several countries with rapidly expanding economies have very fast growth of scientific production on stroke. Our results emphasize the need for stroke research in countries with a high population burden of stroke and they highlight the role of multinational collaboration.

    Abstract [en]

    Background: To compare the publication and citation rate within the areas of drug abuse and dependence research in Europe with that in the USA. Methods: This is a bibliometric study using the Thomson Reuters Web of Knowledge as data source, 40 key words were used as search terms, but certain scientific publications not concerning the issue were excluded. Scientific publications from Denmark, England, Finland, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, and the USA were studied. The number of publications in each country and in each year in addition to the citation indices for these publications was retrieved. Results: Approximately two thirds of the publications came from the USA. Both in absolute and relative figures, Europe lagged behind. The trend over the last decade was a greater gap between the amount of research performed in Europe versus the USA. There were thematic differences. Smaller European countries had a greater relative publication rate. The citations were relatively evenly distributed. Conclusions: It has been claimed that 85% of the world's research within the field of drug abuse and dependence is carried out in the USA. This study challenges this figure, but European research within this field is lagging behind. Copyright (C) 2013 S. Karger AG, Basel

    Entrepreneurial Studies: The Dynamic Research Front of a Developing Social Science2006In: Entrepreneurship Theory and Practice, ISSN 1042-2587, Vol. 30, no 3, p. 375-398Article in journal (Refereed)
    Abstract [en]

    Entrepreneurship research has been built upon a historical foundation grounded in economic change. To understand the development of the field, it is useful to understand the motivations and interests of key scholars and to trace the linkages between these scholars and other authors, from the transient to the contributor. This has been done through a bibliometric analysis of research articles cited between 1982 and 2004. Entrepreneurship has developed from a subdiscipline of management studies reliant on alien terms and cognitive methods toward a separate field with increasing complexities of its own. While not fully mature, entrepreneurship shows all the signs of a maturing field from its increasingly internal orientation and the establishment of key areas of research through to an enhanced, discipline-specific, theoretical approach with a professional language of its own.

    Who's who in venture capital research2006In: Technovation, ISSN 0166-4972, Vol. 26, no 2, p. 142-150Article in journal (Refereed)
    Abstract [en]

    A bibliometric analysis of research papers in venture capital reveals an increasing interest over time by researchers across a broad spectrum of business disciplines. It also reveals the dominance of North American, particularly American researchers who entered the field early. Interestingly, the analysis demonstrates that two schools of entrepreneurial research compete for dominance in the venture capital framework. Much of the core research, the knowledge base, crosses disciplinary lines but is developed, from there-on, in a discipline specific fashion.

    Researchers whose primary interest is in finance and economics use quantitative, neo-classical models almost exclusively and publish, with the exception of the most cited authors, solely in economics and finance journals. These researchers tend to be more successful at achieving internal university funding for their projects while the second group, publishing in journals dedicated to management and entrepreneurship research, uses a broader array of theoretical techniques, apply both quantitative and qualitative methodologies and are more often funded externally. The core group of researchers, with reputations supported by large numbers of citations, appear to be able to raise funds both internally (through university bodies) and externally.

    The first mover and the challenger: The relationship between two journals in organization research1997In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 40, no 3, p. 445-453Article in journal (Refereed)
    Abstract [en]

    Many new journals are started in response to increasing specialization and limited space in existing journals. In this study two journals in organization research are studied,Administrative Science Quarterly as the first mover in the field andOrganization Studies as the challenger. It is shown that the new journal gradually differ from the old in terms of the national origin of its authors as well as the documents cited. It is concluded that the scientific journal market may not mirror the copy-cat behaviour found among newspapers or companies in other markets.

    The development of IB as a scientific field2018In: International Business Review, ISSN 0969-5931, E-ISSN 1873-6149, Vol. 27, no 5, p. 1080-1088Article in journal (Refereed)
    Abstract [en]

    International business (IB) is today an established field in business studies with two professional associations and numerous academic publications. However, it is much younger than many other fields in the management area. Although economists were focusing on international issues even before, it was not until after the Second World War that IB started to emerge as a scientific field. The purpose of this paper is to analyse this development from the early days up to the present time. In so doing, using a theoretical framework, it focuses on the organizing of the field, i.e. how early informal contacts eventually led to the formation of formal organizations, the launching of journals, and with the passage of time the publishing of handbooks. The paper provides empirical evidence of all these steps. In this way it presents data on significant contributions to the field.

    Abstract [en]

    Relationships between commercial actors have existed for thousands of years as highlighted by Hadjikhani and LaPlaca (2013) and Hadjikhani in the final chapter of this volume. However, research on relationships between business actors, often summarised under headings such as industrial marketing or B2B, has a more recent origin. In the words of Hadjikhani and LaPlaca (2013: 294), relationship research 'existed in society but had little scientific identity or inquiry'. This is even truer for research on wider relationship systems, that is, business networks. However, as will be demonstrated in the present volume, the situation in the beginning of the twenty-first century is quite different. Research on business networks is lively and manifested by a large number of publications. A search for 'business networks' in the databases SCI-EXPANDED, SSCI and A&HCI for all years until 2015 (with the restriction that the journals publishing the papers should be classified in the Subject Category 'Business & Economics' in all 156 journals) resulted in 553 hits, with the first papers published in 1992. Publications then did not accelerate until the early twenty-first century with an all-time high in 2012 of 70 hits, and somewhat lower figures in the following years. However, it should be noted that the 2015 figures merely refer to the first part of the year (Fig. 2.1) and will increase.

    Bibliometric Study of Academic Interaction: IT, Organization, and Change2009Conference paper (Refereed)
    Abstract [en]

    This paper explores the degree and nature of the research interaction between the academic fields of Information Technology, Organization, and Organizational Change. This is done so as to see if, and how, the highly digitized modern business world is reflected in related research. The paper analyses 9.669 articles published in 1995-2006 that are derived from major journals within each field. Then the articles are reviewed through the use of the bibliometric methods: frequency, cross-reference, co-citation, shared references, and network analyses. The findings detect a dearth of consistent research interaction between the fields of Information Technology, Organization, and Organizational Change. This fact is critiqued on the basis of previous practical and academic calls for interactional research. The paper provides important insights about the degree and nature of the research interaction and, in addition, recommendations and guidelines for future cross-fertilization between the academic fields are provided.

    The decline of Swedish neuroscience: Decomposing a bibliometric national science indicator2003In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 57, no 2, p. 197-213Article in journal (Refereed)
    Abstract [en]

    Recent studies have reported on a steady decline of Sweden's relative citation impact in almost all science fields, above all in the life sciences. The authors attempt to shed light on the observed decline in Swedish neuroscience through a detailed citation analysis at different level of aggregations. Thus national citation data are decomposed to the institutional, departmental and individual level. Both, the decomposition of national science indicators and changing collaboration patterns in Swedish neuroscience reveal interesting details on the 'anatomy' of a decline.

    Abstract [en]

    The rapid growth of Science and Technology has made the use of scientific information a problem of international concern. To keep abreast of current research the scientist and engineer can use a multitude of information sources. In this study the problem of information use is analysed and a theoretical framework is developed and applied in several case-studies of formal and informal communication. The case-studies include surveys among scientists, engineers and social scientists in different R&D-settings. Information about research is looked upon as a fundamental resource for R&D activities. It is demonstrated that information use and communication behavior are related to research productivity. However the use of both written and oral information sources is limited by barriers related to the individual user, his position in the social structure of the research community and organisation as well as the availability of information resources. In order to improve the use of knowledge it is necessary to integrate the information and documentation functions with the planning and conduct of research. In this context user education and marketing of information resources are important prerequisites. Information search and library use in higher education are analysed and discussed in relation to pedagogical methods and the maintainance of professional competence. Special attention is also given to computerized reference retrieval services and their evaluation.

    Abstract [en]

    Research evaluation is increasingly popular and important among research funding bodies and science policy makers. Various indicators have been proposed to evaluate the standing of individual scientists, institutions, journals, or countries. A simple and popular one among the indicators is the h-index, the Hirsch index (Hirsch 2005), which is an indicator for lifetime achievement of a scholar. Several other indicators have been proposed to complement or balance the h-index. However, these indicators have no conception of aging. The AR-index (Jin et al. 2007) incorporates aging but divides the received citation counts by the raw age of the publication. Consequently, the decay of a publication is very steep and insensitive to disciplinary differences. In addition, we believe that a publication becomes outdated only when it is no longer cited, not because of its age. Finally, all indicators treat citations as equally material when one might reasonably think that a citation from a heavily cited publication should weigh more than a citation froma non-cited or little-cited publication.We propose a new indicator, the Discounted Cumulated Impact (DCI) index, which devalues old citations in a smooth way. It rewards an author for receiving new citations even if the publication is old. Further, it allows weighting of the citations by the citation weight of the citing publication. DCI can be used to calculate research performance on the basis of the h-core of a scholar or any other publication data set. Finally, it supports comparing research performance to the average performance in the domain and across domains as well.

    Mapping the geography of science: Distribution patterns and networks of relations among cities and institutes2010In: Journal of The American Society For Information Science And Technology, ISSN 1532-2882, E-ISSN 1532-2890, Vol. 61, no 8, p. 1622-1634Article in journal (Refereed)
    Abstract [en]

    Using Google Earth, Google Maps, and/or network visualization programs such as Pajek, one can overlay the network of relations among addresses in scientific publications onto the geographic map. The authors discuss the pros and cons of various options, and provide software (freeware) for bridging existing gaps between the Science Citation Indices (Thomson Reuters) and Scopus (Elsevier), on the one hand, and these various visualization tools on the other. At the level of city names, the global map can be drawn reliably on the basis of the available address information. At the level of the names of organizations and institutes, there are problems of unification both in the ISI databases and with Scopus. Pajek enables a combination of visualization and statistical analysis, whereas the Google Maps and its derivatives provide superior tools on the Internet.

    Are highly cited papers more international?2010In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 83, no 2, p. 397-401Article in journal (Refereed)
    Abstract [en]

    Abstract  Several bibliometric studies have shown that international or multicountry papers are generally more cited than domestic or single country papers. Does this also hold for the most cited papers? In this study, the citation impact of domestic versus international papers is analyzed by comparing the share of international papers among the hundred most cited papers in four research specialities, from three universities, four cities and two countries. It is concluded that international papers are not well represented among high impact papers in research specialities, but dominate highly cited papers from small countries, and from cities and institutions within them. The share of international papers among highly cited papers is considerably higher during 2001–2008 compared to earlier years for institutions, cities and countries, but somewhat less for two of the research fields and slightly higher for the other two. Above all, domestic papers from the USA comprise about half of the highly cited papers in the research specialities.

    Exploring the analytical potential of comparing citing and cited source items2006In: Scientometrics, ISSN 0138-9130, Vol. 68, no 3, p. 561-572Article in journal (Refereed)
    Abstract [en]

    Comparing properties of citing and cited source items opens a wide variety of analytical possibilities. In a study of citations among papers in the journal Scientometrics a number of analytical themes are identified. The analysis shows: the way in which a citation graph can be decomposed into different subparts; country specific citation patterns; the effects of self-citations and domestic citations; the mapping of cited author relationships using direct citation and cocitation links; and time slicing effects on impact ranking of countries and papers.

    Identifying research themes with weighted direct citation links2010In: Journal of Informetrics, ISSN 1751-1577, E-ISSN 1875-5879, ISSN 1751-1577, Vol. 4, no 3, p. 415-422Article in journal (Refereed)
    Abstract [en]

    In this study direct citations are weighted with shared references and co-citations in an attempt to decompose a citation network of articles on the subject of library and information science. The resulting maps have much in common with author co-citation maps that have been previously presented. However, using direct citations yields somewhat more detail in terms of detecting sub-domains. Reducing the network down to the strongest links of each article yielded the best results in terms of a high number of clusters, each with a substantial number of articles similar in content.

    Short, Strong and Simple Mapping of Research Fields2011In: Proceedings of ISSI 2011: the 13th Conference of the International Society for Scientometrics and Informetrics, Vols 1 and 2 / [ed] Ed Noyons, Patrick Ngulube and Jacqueline Leta, 2011, p. 662-664Conference paper (Refereed)
    Abstract [en]

    Even within a narrowly defined research speciality, the citations among its papers may form a dense and complex network. In this paper a new mapping approach is suggested and tested on a network of papers on co-citation analysis. One way of mapping the dynamics of the field is to reduce the number of direct citation links by successively minimizing the citation year lag. Another approach is to remove the weakest links from the network. When the two approaches are combined, keeping only short and strong citation links, interesting decompositions of the original citation network was found.

    Citation analysis to reconstruct the dynamics of Antarctic ozone hole research and formulation of the Montreal Protocol2013In: Current Science, ISSN 0011-3891, Vol. 104, no 7, p. 835-840Article in journal (Refereed)
    Abstract [en]

    The ozone layer acts like a shield in safeguarding the Earth by preventing the harmful ultraviolet radiations from entering into the atmosphere. Reported damage to the ozone layer in 1985 was a significant milestone in Antarctic science research. The research work played a significant role in generating international socio-political debate on this great environmental crisis. This article aims to reconstruct the intellectual developments in the field and identify important scientific events which contributed to the formulation of the world’s most successful multilateral treaty, the Montreal Protocol. The dynamics of the research field was mapped using a newly developed indicator – weighted direct citations (WDC). The WDC value indicates intellectual closeness between two citations in terms of co-citations and shared references. Direct citations were weighted with shared references and co-citations to derive WDC values. An attempt was made to decompose the citation network of articles to identify significant activity layers. The work of J. C. Farman et al. (1985) and S. Solomon (1986), which are the top two most cited significant papers in the subject accounts for top WDC values jointly.

    Abstract [en]

    Time and space are fundamental to science dynamics, as science concerns not only what but also where and when. We examine the application of a time-geographical approach in a study of articles citing the works of Torsten Hägerstrand. Citation links between these articles were identified and the links were assigned weights based on shared references and cocitations. The main result is that adding a space-time dimension to traditional bibliometric mapping yields new insight into the dynamics of a research field. It became obvious that change in research is both cognitive and spatial; that is, science changes when it moves.

    Research collaboration at Nordic Universities1997In: Scientometrics, ISSN 0138-9130, E-ISSN 1588-2861, Vol. 39, no 2, p. 209-223Article in journal (Refereed)
    Abstract [en]

    Scientific collaboration has become a major issue in science policy. The need to survey and follow up such collaboration calls for statistical indicators sensitive enough to reveal the structure and change of collaborative networks. Bibliometric analysis of co-authored scientific articles is one promising approach. This study presents data generated from a comprehensive analysis of some 20,000 articles produced by 22 Nordic universities (Denmark, Finland, Iceland, Norway, Sweden) in 1993. The results show that scientific collaboration plays a key role for all universities, and that they collaborate with external institutions in just about the same extent. The inter-Nordic university network comprises about ten percent of all institutional collaborations. However, the amount of collaboration varies across fields, physics and medicine having a high degree of collaboration. The inter-Nordic network is of equal importance as the national network in physics and geosciences. Especially, when one looks at international collaboration outside the Nordic arena, the number of overlapping partners is quite low. This suggests that research specialization is the major force governing international contacts.
