- "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
- Using the library and information science journals 2003-2012 in Nanjing University's Chinese Social Sciences Citation Index as data sources, the paper reveals the citation structure implied in these journals by applying social network analysis. Results show that, first, journal knowledge transfer activity in library and information science is frequent, and both the level of knowledge and discipline integration as well as the knowledge gap influenced knowledge transfer activity. According to the out-degree and in-degree, journals can be divided into three kinds. Second, based on professional bias and citation frequency, the knowledge transfer network can be divided into four blocks. With the change of discipline capacity and knowledge gap among journals, the "core-periphery" structure of the knowledge transfer network is getting weaker. Finally, regions of the knowledge transfer network evolved from a "weak-weak" subgroup to a "strong-weak" subgroup or a "weak-strong" subgroup, and then move to a "strong-strong" subgroup.

- Abstract
- Vom 14. bis 17. Juli fand in Rio de Janeiro die 12th International Conference on Scientometrics and Informetrics statt. Das von den Organisatoren formulierte Ziel der Tagung war es, ein internationals Forum für Wissenschaftler, Wissenschaftsmanager und im Informationsbereich Tätige zu bieten, um den gegenwärtigen Stand und die Fortschritte im Feld szientometrischer Theorien und Anwendungen zu diskutieren. Nachdem die letzten beiden Konferenzen in Europa stattgefunden hatten (Stockholm und Madrid), war mit der Wahl des Tagungsortes zudem der Anspruch verknüpft, einen Beitrag zur weiteren Verbreitung der Szientometrie in lateinamerikanischen Ländern zu leisten. Die Konferenz verzeichnete die in ihrer bisherigen Geschichte höchste Zahl von eingereichten Beiträgen (254), von denen 66 Prozent angenommen wurden. Das endgültige Programm umfasste damit zwei Keynotes, über 90 Vorträge in 21 Sessions sowie 64 Poster. Vor dem Beginn dieses Hauptprogramms der Konferenz fanden darüber hinaus ein Doctoral Forum und drei Workshops zu den Themen "Tracking and evaluating interdisciplinary research: metric and maps", "Visualizing and Analyzing Scientific Literature with CiteSpace" und "Using Maps of Science to Teach Science" statt.

- Abstract
- There is a decrease in the incidence of explicit references to a paper over time, hence the assumption that information ages. In a study which attempts to discover whether information really ages it is necessary to include eponyms, anonyms and footnote references. Reports a pilot study which demonstrates that there is an increase over time in the frequency of use of eponyms

- Abstract
- A model based on a set of bibliometric indicators is proposed for the prediction of the ranking of applicants to an academic position as produced by a committee of peers. The results show that a very small number of indicators may lead to a robust prediction of about 75% of the cases. We start with 12 indicators to build a few composite indicators by factor analysis. Following a discrete choice model, we arrive at 3 comparatively good predicative models. We conclude that these models have a surprisingly good predictive power and may help peers in their selection process.

- Abstract
- In this article we present an empirical approach to the study of the statistical properties of bibliometric indicators on a very relevant but not simply available aggregation level: the research group. We focus on the distribution functions of a coherent set of indicators that are used frequently in the analysis of research performance. In this sense, the coherent set of indicators acts as a measuring instrument. Better insight into the statistical properties of a measuring instrument is necessary to enable assessment of the instrument itself. The most basic distribution in bibliometric analysis is the distribution of citations over publications, and this distribution is very skewed. Nevertheless, we clearly observe the working of the central limit theorem and find that at the level of research groups the distribution functions of the main indicators, particularly the journal- normalized and the field-normalized indicators, approach normal distributions. The results of our study underline the importance of the idea of group oeuvre, that is, the role of sets of related publications as a unit of analysis.

- Abstract
- Properties of a percentile-based rating scale needed in bibliometrics are formulated. Based on these properties, P100 was recently introduced as a new citation-rank approach (Bornmann, Leydesdorff, & Wang, 2013). In this paper, we conceptualize P100 and propose an improvement which we call P100'. Advantages and disadvantages of citation-rank indicators are noted.
