    Abstract
    A recent publication in Nature reports that public R&D funding is only weakly correlated with the citation impact of a nation's articles as measured by the field-weighted citation index (FWCI; defined by Scopus). On the basis of the supplementary data, we up-scaled the design using Web of Science data for the decade 2003-2013 and OECD funding data for the corresponding decade assuming a 2-year delay (2001-2011). Using negative binomial regression analysis, we found very small coefficients, but the effects of international collaboration are positive and statistically significant, whereas the effects of government funding are negative, an order of magnitude smaller, and statistically nonsignificant (in two of three analyses). In other words, international collaboration improves the impact of research articles, whereas more government funding tends to have a small adverse effect when comparing OECD countries.

    Abstract
    This article describes the latest development of a generic approach to detecting and visualizing emerging trends and transient patterns in scientific literature. The work makes substantial theoretical and methodological contributions to progressive knowledge domain visualization. A specialty is conceptualized and visualized as a time-variant duality between two fundamental concepts in information science: research fronts and intellectual bases. A research front is defined as an emergent and transient grouping of concepts and underlying research issues. The intellectual base of a research front is its citation and co-citation footprint in scientific literature - an evolving network of scientific publications cited by research-front concepts. Kleinberg's (2002) burst-detection algorithm is adapted to identify emergent research-front concepts. Freeman's (1979) betweenness centrality metric is used to highlight potential pivotal points of paradigm shift over time. Two complementary visualization views are designed and implemented: cluster views and time-zone views. The contributions of the approach are that (a) the nature of an intellectual base is algorithmically and temporally identified by emergent research-front terms, (b) the value of a co-citation cluster is explicitly interpreted in terms of research-front concepts, and (c) visually prominent and algorithmically detected pivotal points substantially reduce the complexity of a visualized network. The modeling and visualization process is implemented in CiteSpace II, a Java application, and applied to the analysis of two research fields: mass extinction (1981-2004) and terrorism (1990-2003). Prominent trends and pivotal points in visualized networks were verified in collaboration with domain experts, who are the authors of pivotal-point articles. Practical implications of the work are discussed. A number of challenges and opportunities for future studies are identified.

    "Jahrzehntelang galt die USA als Platzhirsch in der Forschungswelt. Egal ob es um Patente oder Nobelpreise ging, ihre Adressaten lebten und arbeiteten zumeist in Nordamerika. Jüngste Zahlen zeigen aber, dass diese Vormachtstellung am Bröckeln ist und Europa und vor allem Asien aufholen. Die globale US-Dominanz könnte zumindest im wissenschaftlichen Bereich bald der Vergangenheit angehören. Während in Österreich gerade die Forschungsförderung restrukturiert wird, machen sich die USA trotz rekordverdächtiger Förderbudgets Sorgen um ihre wissenschaftliche Schlagkraft. Nach einem Artikel in der NewYork Times büsst die USA ihre Führungsrolle in Forschung und Entwicklung zusehends ein. Zwar kommen weiterhin die meisten Patente aus Nordamerika, doch sank deren Anteil an den weltweit angemeldeten Patenten von 60,2% (1980) auf 51,8% (2003). Besonders erfolgreich in diesem Feld sind die asiatischen Ländern, allen voran Japan, das seinen Anteil in den letzten 20 Jahren beinahe verdoppeln konnte. Auch bei den wissenschaftlichen Publikationen holt die nicht englischsprachige WeIt auf. So sank zum Beispiel der Anteil US-amerikanischer Autoren bei Physical Reviewvon über 60% in den 80er Jahren auf unter 30% im letzten Jahr. Auch hier holen besonders Forscher aus Asien stark auf. Allein China reicht jedes Jahr über 1.000 Beiträge bei Physical Review ein, sagt Martin Blume, Herausgeber der Zeitschriften der American Physical Society. Der Anteil der USA an den jährlich vergebenen Nobelpreisen sank in den letzten 30 Jahren ebenfalls deutlich auf knapp über 50%. Asien holt auf: Während Europa die amerikanische Führungsrolle eher vorsichtig herausfordert, hat sich in Asien ein regelrechter Boom entwickelt. Die Zahl der abgeschlossenen naturwissenschaftlichen und techni schen Doktorate verdoppelte sich in Asien in nur zehn Jahren, während die Abschlüsse in Europa und den USA stagnieren oder sogar zurückgehen. Steigender Lebensstandard in den Zentren aller Weltregionen und mobilitätsfeindliche Einreisebestimmungen als Folge des "Kriegs gegen den Terror" führen auch dazu, dass Jungwissenschaftler aus China, Indien oder Taiwan nach Abschluss ihrer Ausbildung in den USA verstärkt in ihre Heimatregion zurückkehren. Die amerikanische Wirtschaft reagiert auf diesen Trend zunehmend mit der Auslagerung von Forschungseinrichtungen in diese Länder. In Zeiten der Globalisierung zeigt sich daran aber auch die Schwäche nationalstaatlich orientierter Statistiken."

    Abstract
    Vom 5. bis 7. November 2003 findet auf Initiative und in der Verantwortung der Zentralbibliothek des Forschungszentrums Jülich die Konferenz "Bibliometric Analysis in Science and Research" statt: Bibliometrische Indikatoren, Bibliomefrisches Mapping, Webmetrie und Forschungspolitik stehen auf dem Programm. Nach einer Phase der Beruhigung auf dem Bibliometriesektor scheint dieses Forschungsfeld nun von der Bibliothekswissenschaft wieder eine Belebung zu erfahren. Vor allem in den 80erJahren wurden Gesetze von Bradford, Lotka und Zipf heiß diskutiert. Halbwertszeiten, Forschungsfronten und Kernzeitschriften sind Dank der Datenbanken des ISI problemlos aufzuspüren und werden gerne zur Selbstbespiegelung der Wissenschaft benutzt (Diodalo 1994). Die Zeitschrifen Scientometrics und die JASIST belegen, dass die mathematischen Modellierungen auf diesem Gebiet noch immer nicht an ihre Grenzen gestoßen sind. Und Vereinigungen wie die Gesellschaft für Wissenschaftsforschung oder die ISSI und deren Diskussionsliste oder Sigmetrics zeigen, dass nach wie vor eine starke Community auf diesem Gebiet aktiv ist. Andererseits hat der Begriff Bibliometrie ein wenig von seinem schillernden Glanz verloren und wird gerne durch Mapping, Cybermetrics (gleichnamig das "International Journal of Scientometrics, Informetrics and Bibliometrics"), Information Mining und anders in modernere Kontexte gesetzt (Park/Thelwall 2003). War es das relativierende Wissenschaftsverständnis, der Wegfall der konkurrierenden politischen Systeme oder die stürmische Medienentwicklung in der Wissenschaft, welche die Bibliometrie aus der Bibliotheks- und Informationsdiskussion vorübergehend verschwinden ließ?

    Abstract
    The present paper analyzes the changes that occurred to a set of Web pages related to "informetrics" over a period of 5 years between June 1998 and June 2003. Four times during this time span, in 1998,1999, 2002, and 2003, we monitored previously located pages and searched for new ones related to the topic. Thus, we were able to study the growth of the topic, white analyzing the rates of change and disappearance. The results indicate that modification, disappearance, and resurfacing cannot be ignored when studying the structure and development of the Web.
