Co-authorship networks in Swiss political research
Co-authorship is an important indicator of scientific collaboration. Co-authorship networks are composed of sub-communities, and researchers can gain visibility by connecting these insulated subgroups. This article presents a comprehensive co-authorship network analysis of Swiss political science. Three levels are addressed: disciplinary cohesion and structure at large, communities, and the integrative capacity of individual researchers. The results suggest that collaboration exists across geographical and language borders even though different regions focus on complementary publication strategies. The subfield of public policy and administration has the highest integrative capacity. Co-authorship is a function of several factors, most importantly being in the same subfield. At the individual level, the analysis identifies researchers who belong to the âinner circleâ of Swiss political science and who link different communities. In contrast to previous research, the analysis is based on the full set of publications of all political researchers employed in Switzerland in 2013, including past publications
National and International Dimensions of the Triple Helix in Japan: University-Industry-Government versus International Co-Authorship Relations
International co-authorship relations and university-industry-government
("Triple Helix") relations have hitherto been studied separately. Using
Japanese (ISI) publication data for the period 1981-2004, we were able to study
both kinds of relations in a single design. In the Japanese file, 1,277,823
articles with at least one Japanese address were attributed to the three
sectors, and we know additionally whether these papers were co-authored
internationally. Using the mutual information in three and four dimensions,
respectively, we show that the Japanese Triple-Helix system has continuously
been eroded at the national level. However, since the middle of the 1990s,
international co-authorship relations have contributed to a reduction of the
uncertainty. In other words, the national publication system of Japan has
developed a capacity to retain surplus value generated internationally. In a
final section, we compare these results with an analysis based on similar data
for Canada. A relative uncoupling of local university-industry relations
because of international collaborations is indicated in both national systems
Collaboration in an Open Data eScience: A Case Study of Sloan Digital Sky Survey
Current science and technology has produced more and more publically
accessible scientific data. However, little is known about how the open data
trend impacts a scientific community, specifically in terms of its
collaboration behaviors. This paper aims to enhance our understanding of the
dynamics of scientific collaboration in the open data eScience environment via
a case study of co-author networks of an active and highly cited open data
project, called Sloan Digital Sky Survey. We visualized the co-authoring
networks and measured their properties over time at three levels: author,
institution, and country levels. We compared these measurements to a random
network model and also compared results across the three levels. The study
found that 1) the collaboration networks of the SDSS community transformed from
random networks to small-world networks; 2) the number of author-level
collaboration instances has not changed much over time, while the number of
collaboration instances at the other two levels has increased over time; 3)
pairwise institutional collaboration become common in recent years. The open
data trend may have both positive and negative impacts on scientific
collaboration.Comment: iConference 201
Authorship analysis of specialized vs diversified research output
The present work investigates the relations between amplitude and type of
collaboration (intramural, extramural domestic or international) and output of
specialized versus diversified research. By specialized or diversified
research, we mean within or beyond the author's dominant research topic. The
field of observation is the scientific production over five years from about
23,500 academics. The analyses are conducted at the aggregate and disciplinary
level. The results lead to the conclusion that in general, the output of
diversified research is no more frequently the fruit of collaboration than is
specialized research. At the level of the particular collaboration types,
international collaborations weakly underlie the specialized kind of research
output; on the contrary, extramural domestic and intramural collaborations are
weakly associated with diversified research. While the weakness of association
remains, exceptions are observed at the level of the individual disciplines
International Collaboration in Science and the Formation of a Core Group
International collaboration as measured by co-authorship relations on
refereed papers grew linearly from 1990 to 2005 in terms of the number of
papers, but exponentially in terms of the number of international addresses.
This confirms Persson et al.'s (2004) hypothesis of an inflation in
international collaboration. Patterns in international collaboration in science
can be considered as network effects, since there is no political institution
mediating relationships at that level except for the initiatives of the
European Commission. During the period 2000-2005, the network of global
collaborations appears to have reinforced the formation of a core group of
fourteen most cooperative countries. This core group can be expected to use
knowledge from the global network with great efficiency, since these countries
have strong national systems. Countries at the periphery may be disadvantaged
by the increased strength of the core
Bibliometric studies on single journals: a review
This paper covers a total of 82 bibliometric studies on single journals (62 studies cover unique titles) published between 1998 and 2008 grouped into the following fields; Arts, Humanities and Social Sciences (12 items); Medical and Health Sciences (19 items); Sciences and Technology (30 items) and Library and Information Sciences (21 items). Under each field the studies are described in accordance to their geographical location in the following order, United Kingdom, United States and Americana, Europe, Asia (India, Africa and Malaysia). For each study, elements described are (a) the journalâs publication characteristics and indexation information; (b) the objectives; (c) the sampling and bibliometric measures used; and (d) the results observed. A list of journal titles studied is appended. The results show that (a)bibliometric studies cover journals in various fields; (b) there are several revisits of some journals which are considered important; (c) Asian and African contributions is high (41.4 of total studies; 43.5 covering unique titles), United States (30.4 of total; 31.0 on unique titles), Europe (18.2 of total and 14.5 on unique titles) and the United Kingdom (10 of total and 11 on unique titles); (d) a high number of bibliometrists are Indians and as such coverage of Indian journals is high (28 of total studies; 30.6 of unique titles); and (e) the quality of the journals and their importance either nationally or internationally are inferred from their indexation status
