    No full text
    The structure of scientific collaboration networks in scientometrics was investigated at the level of individuals by using bibliographic data of all papers published in the international journal Scientometrics retrieved from the Science Citation Index (SCI) during 1978 to 2004. Combined analysis of social network analysis (SNA), co-occurrence analysis, cluster analysis and frequency analysis of words was explored to reveal: (1) The microstructure of the collaboration network on scientists’ aspects of scientometrics; (2) The major collaborative fields of the collaborative sub-networks; (3) The collaborative center of the collaboration network in scientometrics

    Collaboration in Iranian Scientific Publications

    No full text
    This study looks at international collaboration in Iranian scientific publications through the ISI Science Citation Index® (SCI) for the years 1995-1999, inclusive. These results are compared to and contrasted with the earlier findings for the periods covering 1985-1994 (Osareh & Wilson 2000). The results of Iran's increasing productivity over a 15-year period are presented. Iran doubled its output in the first two five-year periods and increased 2.8-fold from the second to the third five-year period. The rise in Iran's scientific publication output is due mainly to factors such as the ending of the war, better economic conditions, recent changes in the Iranian government's policy, basic changes in the political environment brought about by the Reformers, expansion of the Iranian presses for national publications, and the recent return of a large number of students trained overseas through government scholarships. External changes also account for the increased productivity, e.g., the acceptance of three Iranian source journals by the SCI, increased access to international databases through the Internet and better electronic communication facilities for international collaboration. One of the most important and significant factors that caused this dramatic rise seems to be the government's research policies in the last few years. Since 1999, the Iran Science, Research and Technology Ministry, has encouraged researchers to publish their non-Farsi language articles in highly ranked international scientific journals, for example, by giving prizes to researchers who publish their articles in ISI-ranked journals

    This paper examines the co-authorship network in the field of scientometrics using social network analysis techniques with the aim of developing an understanding of research collaboration in this scientific community. Using co-authorship data from 3125 articles published in the journal Scientometrics with a time span of more than three decades (1980-2012), we construct an evolving co-authorship network and calculate three centrality measures (closeness, betweenness, and degree) for 3024 authors, 1207 institutions, 68 countries and 22 academic fields in this network. This paper also discusses the usability of centrality measures in author ranking, and suggests that centrality measures can be useful indicators for impact analysis. Findings revealed that scientometrics was not dominated by a couple of key researchers as quite a significant number of popular researchers were identified. The United States occupies the topmost position in all measures except for degree centrality. The most active, central and collaborative academic discipline in scientometrics is Information & Library Science

    Dialogue and Collaboration in the Creation of New Works for Clarinet

    No full text
    This PhD thesis explores dialogue-based, “intimate” collaboration through the creation of new works for clarinet. It borrows from Grounded Theory in order to facilitate an analysis through which emergent themes within a dialogue-based collaboration are discovered. The aim has not been to insist on one model of collaboration, but to discover methods for improving one’s collaborative skills and to identify ways in which one benefits from a focus on dialogue in collaboration. Furthermore, it aims to suggest that through collaboration one can make discoveries about the instrument: original contributions to clarinet technique are made within this thesis. The literature from which the research draws inspiration to further collaborative “technique” is cross-disciplinary and wide-ranging: it draws from social theory, collaborative creative writing, dance, the visual arts and of course, music. Added to this is a select discussion of collaboration throughout the repertoire of the clarinet. Finally, this consists of practice-based research. Seven new pieces for clarinet accompany the text

    Testing models of collaboration among high school science teachers in an electronic environment

    Teacher collaboration is one of the strategies for encouraging teaches to work together to achieve their common ends. In a complex modern world, teachers rarely have time to collaborate with each other. E-mail and Internet technology encourages teacher collaboration to emerge with personal interaction. E-mail is rapid, permitting responses within the same day or even a few hours. On the network, teachers can seek advice from teachers on other campuses and around the world, and at the same time, they can build their relationship with other users. In Western Australia, an e-mail network for science curriculum leaders was established in both primary and secondary schools. In 1998, a study showed that 93 heads of science departments in government high schools were connected to this e-mail network, and more than two-thirds of them had their computers connected to the World Wide Web. This study aims to: firstly, test Fishbough's models of collaboration among high school science teachers in an electronic environment (e-mail and Internet); and secondly, presents a detailed science web site analysis in terms of the potential of these websites to foster collaboration. The investigation is divided into two distinct studies: Study One is a survey of the teachers' perceptions of collaboration via the Internet and Study Two is a detailed science website analysis. Study One employed both mail questionnaire and face-to-face interview techniques as methods of data collection. The Science Teacher Collaboration via E-mail and Internet Questionnaire was developed and used to collect data on models of collaboration and interaction perspective of collaborative relationships via the Internet of science teachers at the selected schools. The information from quantitative analysis was used to compose the interview schedule. The follow-up interview was conducted with science teachers who agreed to be interviewed at the sample schools. Study Two adopted a content analysis technique for analysis of data collected from the two kinds of science websites, specific science websites for science teachers and science websites for general audiences from five chosen continents, Australia, Asia, Europe, America and Africa. The study found that the Consulting model of collaboration is frequently used by science teachers and science web sites from five chosen continents

    Inter-institutional scientific collaboration: an approach from social network

    No full text
    This paper presents a tool that can be used to characterize, analyze and interpret the patterns of collaboration among institutions by means of the visual display of scientific information. These graphic representations allow for a combined analysis of a given institution in the system of relations (network), and of the particular attributes of that institution (indicators). The tool affords the possibility of regenerating the network to make any number of aggregates appear or disappear, thus allowing one to focus on institutional sectors, geographic regions, etc. It also allows for analysis of sectorial interaction, institutional backing of research, and the influence of geographic proximity, linguistic affinity, or regional politics. This is indeed a versatile analytical tool, and it is bound to prove its potential for evaluating patterns of collaborative research, development and innovation

    The methodological status of co-authorship networks

    No full text
    A powerful strategy within the study of collaboration in science is to posit that co-authorship patterns represent social networks. It is prerequisite to an application of Social Network Analysis (SNA) to define the network entities. A network analysis of the inter-institutional collaboration in COLLNET on the basis of co-authorships was conducted. The study reveals that it is crucial whether the co-authorship itself is seen as an author's relational property or as a social event that brings the authors together. The former possibility is represented by a onemode network in which each author can be related to each other author. Quite distinct from that are two-mode networks, the latter approach. They consist of two single data sets in which relations are only possible between different sets. Different modes of representations require different network approaches. One is that co-authorship networks are seen as one-mode networks, which has the advantage of the application of a variety of measures. In contrast, twomode networks, the other option, cannot be analysed by standard techniques but its distinctive features demand a new conceptualisation of measures. In conclusion, the two-mode perspective is more promising because it allows a dual perspective on collaboration in science which includes researchers as well as their scientific output

    Relationship among research collaboration, number of documents and number of citations. A case study in Spanish computer science production in 2000-2009.

    This paper analyzes the relationship among research collaboration, number of documents and number of citations of computer science research activity. It analyzes the number of documents and citations and how they vary by number of authors. They are also analyzed (according to author set cardinality) under different circumstances, that is, when documents are written in different types of collaboration, when documents are published in different document types, when documents are published in different computer science subdisciplines, and, finally, when documents are published by journals with different impact factor quartiles. To investigate the above relationships, this paper analyzes the publications listed in the Web of Science and produced by active Spanish university professors between 2000 and 2009, working in the computer science field. Analyzing all documents, we show that the highest percentage of documents are published by three authors, whereas single-authored documents account for the lowest percentage. By number of citations, there is no positive association between the author cardinality and citation impact. Statistical tests show that documents written by two authors receive more citations per document and year than documents published by more authors. In contrast, results do not show statistically significant differences between documents published by two authors and one author. The research findings suggest that international collaboration results on average in publications with higher citation rates than national and institutional collaborations. We also find differences regarding citation rates between journals and conferences, across different computer science subdisciplines and journal quartiles as expected. Finally, our impression is that the collaborative level (number of authors per document) will increase in the coming years, and documents published by three or four authors will be the trend in computer science literature

    Measurements of Electric Dipole Moments of Charged Particles at Storage Rings

    No full text
    Electric Dipole Moments (EDM) of elementary particles are considered to be one of the most powerful tools to investigate CP violation beyond the Standard Model and to find an explanation for the dominance of matter over antimatter in our universe. Up to now experiments concentrated on neutral systems (neutrons, atoms, molecules). Storage rings offer the possibility to measure EDMs of charged particles by observing the influence of the EDM on the spin motion. The Cooler Synchrotron COSY at the Forschungszentrum J\'ulich provides polarized protons and deuterons up to a momentum of 3.7 GeV/c and is thus an ideal starting point for such an experimental program. The JEDI (J\'ulich Electric Dipole moment Investigations) Collaboration has been formed to exploit the COSY facility to demonstrate the feasibility of such a measurement and to perform all the necessary investigations towards the design of a dedicated storage ring
