Abstract: We utilize the bibliometric tool of co-word analysis to identify trends in the methods and subjects of ecology during the period 1970-2005. Few previous co-word analyses have attempted to analyze fields as large as ecology. We utilize a method of isolating concepts and methods in large datasets that undergo the most significant upward and downward trends. Our analysis identifies policy-relevant trends in the field of ecology, a discipline that helps to identify and frame many contemporary policy problems. The results provide a new foundation for exploring the relations among public policies, technological change, and the evolution of science priorities.

Abstract: The gender gap in science and technology has received considerable attention by both researchers and policy makers. In an effort to better understand the quantity, quality, and underlying characteristics of female research efforts, I integrate three existing databases to uncover how female patenting activities differ from men’s in the US biotechnology industry. Data on how much science the patents build upon, the author institutions of that science, and who funded the papers in which the science appears are all examined. In addition, using the NBER Patent Citation Data Files, I propose a possible gender-based life cycle model for patenting activity. The policy implications of my findings are also discussed.

Abstract: A bibliometric analysis was performed on a set of 1718 documents relating to Web 2.0 to explore the dimensions and characteristics of this emerging field. It has been found that Web 2.0 has its root deep in social networks with medicine and sociology as the major contributing disciplines to the scholarly publications beyond its technology backbone - information and computer science. Terms germane to Web 2.0, extracted from the data collected in this study, were also visualized to reflect the very nature of this rising star on the Internet. Web 2.0, according to the current research, is of the user, by the user, and more importantly, for the user.

Full Text: 2009\Scientometrics80, 731.pdf

Abstract: An intellectual property (IP)-centric, communication-based Innovation Agenda is proposed and investigated. The agenda, which is aligned with IP legal prescription, is defined as follows: the firm’s R&D expenditure is captured within products. The firm applies for a patent and files a trademark to protect its interests in the ‘patentable’ product, and issues a media communication, which may alter the perception of future cash flows, and thereby market price. Upon patent issuance and trademark registration, the firm will then seek another media communication. Spearman (partial) correlation analysis shows strong correlation among the various proxy metrics suggesting that the model basis may exist. The model proposes a novel link among national socioeconomic metrics, corporate strategy, and the technology based innovative firm. Finally, the model supports the inclusion of trademark and media communications data to be considered in socioeconomic modeling.

Full Text: 2009\Scientometrics80, 747.pdf

Abstract: The practice of publishing clinical trials in scientific journals is common, although not without its critics. This study aims to measure the effect of clinical trials citations on several bibliometric indicators: citations per document (CD), journal impact factor (JIF), relative h-index (RhI) and strike rate index (SRI). We select all the citable documents published in the NEJM, Lancet, JAMA, AIM and BMJ, for the period 2000-2004, and record the citations received by those papers from 2000 to 2005. Our results show that clinical trials have a CD significantly higher than those for conventional papers, JIF is lower when clinical trials are excluded, especially for NEJM, Lancet and JAMA. Finally, both RhI and SRI seem to be unaffected by clinical trials citations.

Abstract: In this work, we compare the difference in the number of citations compiled with Scopus as opposed to the Web of Science (WoS) with the aim of analysing the agreement among the citation rankings generated by these databases. For this, we analysed the area of Health Sciences of the University of Navarra (Spain), composed of a total of 50 departments and 864 researchers. The total number of published works reflected in the WoS during the period 1999-2005 was 2299. For each work, the number of citations in both databases was recorded. The results indicate that the works received 14.7% more citations in Scopus than in WoS. In the departments, the difference was greater in the clinical ones than in the basic ones. In the case of the rankings of citations, it was found that both databases generate similar results. The Spearman and Kendall-Tau coefficients were higher than 0.9. It was concluded that the difference in the number of citations found did not correspond to the difference of coverage of WoS and Scopus.

Abstract: This paper analyses the changing geographic balance in China’s international co-publications in general and in three molecular life science subfields in particular. No support is found for the expectation that intensive, designated institutional support for research collaboration in the form of joint laboratories has a positive impact on the number of co-publications at the systemic level. The size of partner research systems, and since the turn of the century the relative size of overseas Chinese scientific communities in various partner countries do help to explain the observed geographic variations in the share of China’s international co-publications. The paper concludes by discussing some of the potential factors underlying the perceived change in the dynamics of international co-publication behavior of mainland Chinese scientists since the turn of the century.

Abstract: It appears popular, particularly among science administrators, to use citations and various citation measures for ranking scientists, as if such exercises would reflect the scientific potential of the persons considered. In recent time the Hirsch index h in particular has obtained visibility in this respect in view of its simplicity. We consider a possible extension of the concept of selective citations, which in fact is innate to the h index, and propose a simple generalization, indices H and Q, which to a degree supplement the information accompanying the evaluation of h. The H index keeps record of the “history” of citations and the quotient Q = H/h is a measure for the quality of a scientist based on the history of his/her citations.

Abstract: This article introduces the generalized Kosmulski-indices as a new family of scientific impact measures for ranking the output of scientific researchers. As special cases, this family contains the well-known Hirsch-index h and the Kosmulski-index h ((2)). The main contribution is an axiomatic characterization that characterizes every generalized Kosmulski-index in terms of three axioms.

Abstract: Future political priorities for science and technology (S&T) policy formulation usually rest on a rather simplistic interpretation of past events. This can lead to serious errors and distortions and can negatively affect the innovation system. In this article we try to highlight the riskiness involved in policy making based on traditional R&D indicators and trends. We would emphasise that this approach does not take account of structural aspects crucial for the analysis of the innovation system. We examine the implications for science, technical and human resources policies of the political challenge of R&D convergence in a peripheral EU region. Three scenarios are developed based on application of the same criteria to the trends observed in traditional R&D input indicators.

Abstract: Increasingly, collaboration between firms as well as science-industry interactions are being considered as important for technology development. Yet, few attempts have been made to analyze the contribution of collaboration, taking into account different stages of the technology life cycle. Our analysis, based on a panel of 197 regions in the EU-15 and Switzerland (time period 1978-2001), provides evidence that, in the field of biotechnology, science-industry collaboration contributes to better technological performance of regions both during the emerging phases (1978-1990) and the growth stages (1991-1999) of the life cycle. Collaboration between industrial partners also contributes to the technological performance of regions during the first phase but is less pronounced during later phases of the technology life cycle. Moreover, the analysis reveals that, as technologies develop over time, the impact of local collaboration is mitigated in favor of collaboration that has an international dimension. This holds true for both science-industry interactions and for collaboration between firms. In consequence, our findings underscore the relevance of incorporating life cycle dynamics (of technologies) when studying the nature and impact of collaboration on the technological performance of regions.

Abstract: By their widespread availability and dissemination through open access media, scholarly outputs witness an improved visibility supposed to cause a better citation performance. However, due to the existence of the Matthew effect in science system, which affects users’ perceptions of quality, ultimate effects of the enhanced visibility on different entities are obscure. Moreover, different attitudes towards open access give rise to a more strong quality dynamics in the open access world. Aiming to explore the consequence of the interaction between visibility and quality dynamics, this study investigates countries positioning in open access journals. The results show that the world’s countries welcome open access pattern whether by submitting to or publishing open access journals. A large proportion of the enduring, prestigious open access journals are published by scientifically proficient and developing nations, emphasizing their successful commitment to maintain the undertaken role. The results of the citation analysis highlight national inequalities regarding citation distributions among countries contributing to the journals within the system and within individual disciplines in the system. Well-performing countries mainly consist of advanced ones, however, some lessdeveloped nations are found to perform well in the journal system.

Abstract: Author co-citation analysis (ACA) is an important method for discovering the intellectual structure of a given scientific field. Since traditional ACA was confined to ISI Web of Knowledge (WoK), the co-citation counts of pairs of authors mainly depended on the data indexed in WoK. Fortunately, Google Scholar has integrated different academic databases from different publishers, providing an opportunity of conducting ACA in wider a range. In this paper, we conduct ACA of information science in China with the Chinese Google Scholar. Firstly, a brief introduction of Chinese Google Scholar is made, including retrieval principles and data formats. Secondly, the methods used in our paper are given. Thirdly, 31 most important authors of information science in China are selected as research objects. In the part of empirical study, factor analysis is used to find the main research directions of information science in China. Pajek, a powerful tool in social network analysis, is employed to visualize the author co-citation matrix as well. Finally, the resemblances and the differences between China and other countries in information science are pointed out.

Abstract: In scientometrics for trend analysis, parameter choices for observing trends are often made ad hoc in past studies. For examples, different year spans might be used to create the time sequence and different indices were chosen for trend observation. However, the effectiveness of these choices was hardly known, quantitatively and comparatively. This work provides clues to better interpret the results when a certain choice was made. Specifically, by sorting research topics in decreasing order of interest predicted by a trend index and then by evaluating this ordering based on information retrieval measures, we compare a number of trend indices (percentage of increase vs. regression slope), trend formulations (simple trend vs. eigen-trend), and options (various year spans and durations for prediction) in different domains (safety agriculture and information retrieval) with different collection scales (72500 papers vs. 853 papers) to know which one leads to better trend observation. Our results show that the slope of linear regression on the time series performs constantly better than the others. More interestingly, this index is robust under different conditions and is hardly affected even when the collection was split into arbitrary (e.g., only two) periods. Implications of these results are discussed. Our work does not only provide a method to evaluate trend prediction performance for scientometrics, but also provides insights and reflections for past and future trend observation studies.

Full Text: 2009\Scientometrics81, 91.pdf

Abstract: A frequently used indicator for assessing technological strengths of nations are patents registered in the triad region, i.e. in North America, Europe, and Asia. Currently these so-called triadic patents are defined as filed at the United States Patent and Trademark Office (USPTO), the European Patent Office (EPO), and the Japanese Patent Office (JPO). Recent developments suggested that this definition might lack adequacy regarding the offices in Europe and Asia. Our findings propose that in particular Germany and China should be added to this triad definition since in some technology fields patents registered in these countries show the same citation impact as patents registered at the EPO or JPO. Our results also underline that the number of triadic patent families per country is a function of technological specialization and (national) patenting strategies.

Abstract: In this paper we investigate the position of a review network within a research specialty, the network of scholars who write reviews of their colleagues’ work. This is one of the voluntary activities that researchers perform as a prerequisite for the functioning of the invisible college. We compare this network to other networks within the specialty, and this allows us to distinguish various roles: stars, influentials, members, reviewers and juniors. As scholars are characterized by different role-configurations, the invisible college becomes stratified. We discuss the implications for the development of a referee factor and review factor, norms for refereeing and reviewing, and the development of systems-based research evaluations.

Abstract: This paper surveys 32 renowned Industrial Engineering (IE) journals with regard to authorship for the period of 1996-2005. The findings show that the USA was the top contributing country, accounting for approximately one-third of the total number of articles. The 80/20 rule and the entropy measure consistently identify Issues in Science and Technology (IST), Industrial Engineer (IE), and R&D Magazine (RDM) as journals of high country concentration, or journals of low internationality. Conversely, Journal of Materials Processing Technology (JMPT), Production Planning & Control (PPC), and Technovation (TNV) have the highest degree of country diversity, or internationality. The quality of a journal, as expressed by impact factors, its internationality, and its number of articles published, are found to be independent of each other.
