Publishing in international journals

This paper examines patterns of Chinese authorship, focusing particularly on international co-authorship, in a sample of 37,526 articles from Elsevier journals published in 2004. Trends relating to potential influences such as subject, journal impact factor and article type are explored. A slightly higher proportion of articles with at least one Chinese author was observed as compared to previous studies. Articles that are a product of Chinese international collaboration account for almost 20% of the Chinese sample as a whole, a similar proportion to levels of international collaboration within the sample overall. Chinese international co-authorship is most common in the Earth & Environmental Sciences. Where China is involved in international collaboration, it is often a proactive participant: 49% of articles that are a result of Chinese international collaboration have a Chinese corresponding author. With some minor variations in subject categories, countries favoured in international co-authorship reflect world shares in publishing and factors such as geographical proximity and political links. In the context of this project, the term ‘Chinese authors’ is used to refer to authors, regardless of nationality, who are based at Chinese institutions. The term does not include Chinese nationality authors who are based in institutions outwith China.     

Core-periphery,new clusters,or rising stars?: international scientific collaboration among ‘advanced’ countries in the era of globalization

Assuming the OECD member states as ‘advanced’ nations equipped with basic scientific capacities, the present research addresses the network configuration of these countries in international scientific collaboration and the transformation of this network along with globalization. The result suggests that geographical, linguistic, and economic affinities did not have a meaningful impact on the formation of co-authorship network between ‘advanced’ nations, different from previous research results which claimed their importance on international cooperation. Globalization facilitated by the development of information and transportation technologies was found to influence the co-authorship link between countries, but not to accelerate centralization of the network in the past 15 years. Though the core-periphery pattern still persists, new rising stars, which are Korea and Turkey, have emerged in the co-authorship network among ‘advanced’ nations. These two countries, having a rapid increase in the share of degree centrality from 1995 to 2010, had strategic financial support from the government which stimulated the collaboration between universities and industries and emphasized the development of science and engineering fields.     

Out of particles: Impact of CERN, DESY and SLAC research to fields other than physics

This paper presents the results of an exploratory bibliometric study aiming at an analysis of basic high energy physics (HEP) research impact on fields other than physics, and particularly on application-oriented R&D. After a general discussion of an extensive citation analysis of basic research publications from three HEP institutes—CERN, DESY, and SLAC—the paper focuses on the ‘knowledge flow’ from physics to non-physics, and more specifically the flow from basic physics research to the ‘applied world’. At this level, we report journal- as well as research field characteristics, and we identify the most frequently citing R&D groups. We conclude that DESY is most cited by the ‘applied world’, followed by SLAC and CERN. If the number of journals that institutes have in common—whether based on the source or the citing publication—is taken as an indicator of the resemblance of their research interests, we found that CERN and SLAC have the closest resemblance, followed by SLAC and DESY, with CERN and DESY having the least in common.     

Investigating different types of research collaboration and citation impact: a case study of Harvard University’s publications

This study aims to investigate the influence of different patterns of collaboration on the citation impact of Harvard University’s publications. Those documents published by researchers affiliated with Harvard University in WoS from 2000–2009, constituted the population of the research which was counted for 124,937 records. Based on the results, only 12% of Harvard publications were single author publications. Different patterns of collaboration were investigated in different subject fields. In all 22 examined fields, the number of co-authored publications is much higher than single author publications. In fact, more than 60% of all publications in each field are multi-author publications. Also, the normalized citation per paper for co-authored publications is higher than that of single author publications in all fields. In addition, the largest number of publications in all 22 fields were also published through inter-institutional collaboration and were as a result of collaboration among domestic researchers and not international ones. In general, the results of the study showed that there was a significant positive correlation between the number of authors and the number of citations in Harvard publications. In addition, publications with more number of institutions have received more number of citations, whereas publications with more number of foreign collaborators were not much highly cited.     

The state of science and technology in Africa (2000–2004): A scientometric assessment

This article reports for first time the state of science and technology in the African Continent on the basis of two scientometric indicators — number of research publications and number of patents awarded. Our analysis shows that Africa produced 68,945 publications over the 2000–2004 period or 1.8% of the World’s publications. In comparison India produced 2.4% and Latin America 3.5% of the World’s research. More detailed analysis reveals that research in Africa is concentrated in just two countries — South Africa and Egypt. These two counties produce just above 50% of the Continent’s publications and the top eight countries produce above 80% of the Continent’s research. Disciplinary analysis reveals that few African countries have the minimum number of scientists required for the functioning of a scientific discipline. Examination of the Continent’s inventive profile, as manifested in patents, indicates that Africa produces less than one thousand of the world’s inventions. Furthermore 88% of the Continent’s inventive activity is concentrated in South Africa. The article recommends that the African Governments should pay particular attention in developing their national research systems.     

The global science base of information and communication technologiges: Bibliometric analysis of ICT research papers

The science and engineering base is a key source of knowledge for the development and use of Information and Communication Technologies (ICTs). In order to be able to effectively describe and monitor world-wide scientific activity related to ICTs, it is important to be able to provide reliable macro-level statistics of this knowledge base. International bibliographic databases and related bibliometric indicators together provide an analytical framework and appropriate measures to cover both the ‘supply side’—research capabilities and outputs—and ‘demand side’—collaboration, diffusion and citation impact—related to the ICT research. This paper presents results of such a bibliometric study describing macro-level features of this ICT knowledge base. The data were retrieved from a specially developedCWTS ICT Database which provides a broad-scope world-wide coverage of ICT-relevant research papers published in high-quality international scientific and technical journals. The cross-country comparison focuses on the level of scientific output and co-operation patterns of the most actively publishing nations with a focus on the three Triad zones—the European Union, the USA and Japan.     

South–South research collaboration of countries in the Southern African Development Community (SADC)

This study investigates South–South collaboration in research, and specifically collaboration among the 15 countries of the Southern African Development Community (SADC) as well as between the SADC and the rest of Africa. It was found that only 3% of SADC papers during 2005–2008 were jointly authored by researchers from two or more SADC countries (intra-regional collaboration), and only 5% of SADC papers were jointly authored with researchers from African countries outside the SADC (continental collaboration). In contrast, 47% of SADC papers were co-authored with scientists from high-income countries. The few instances of intra-regional and continental collaboration in the SADC are largely the product of North–South collaboration. Authors from high-income countries are included in 60% of intra-regional co-authored papers and in 59% of continental co-authored papers. Moreover, between 2005 and 2008, South Africa produced 81% of all SADC papers and 78% of all intra-regional co-authored papers. This implies that there is a highly unbalanced and unequal partnership that can best be described as a variant of North–South collaboration with the scientific giant in the South taking on the role of the ‘political North’. As a consequence, guidelines for successful North–South collaborations should be extended to include South–South collaborations that comprise highly unequal partners, as is the case between South Africa and the other SADC countries.     

Collaboration in theoretical population genetics speciality

Analyses the growth of funded and collaborative research publications and authors as reflected in selected theoretical population genetics literature from 1956–60 to 1976–80. Indicates that the number of funded and collaborated publications has not proportionally increased along with the growth of total research publications and authors with time, but however, there is a strong correlation between the two. Indicates the extent of multi-authored research publications in different countries, and studies the growth of multi-authored publications from 1956–60 to 1976–80. Studies the impact of funding and collaboration on the productivity of authors over a period of time. Concludes that the authors who are more productive are generally found to be more collaborative and funded. The average productivity per author is observed to be larger in funded and collaborated authors subset and smaller in non-funded and non-collaborated authors subset, than the average productivity per author in the total authors subset in all the five block years studied. There is a systematic increase with time in the average productivity per author in the funded and collaborated authors subset. Studies the nature and type of collaborated research from 1956–60 to 1976–80, and the role of funding. Highlights the research priorities of few important countries in collabortive research. Indicates the collaboration linkages among various countries in transnational collaborative research. Concludes that with time, the focus of research is slowly shifting from internal collaration to domestic and international collaboration, supported by increasing funding from government agencies in theoretical population genetics research.     

Skeletal tissues as nanomaterials

Collagen is the most abundant protein in the body and, though the fibre-forming collagens have a ‘common’ structure, it is adapted to perform a large range of functions—from the differing mechanical needs of tendon versus bone to forming a transparent support structure in the cornea. This perfidy also suggests that collagen could form a generic basis for a range of scaffold needs for tissue engineering or medical device coating applications. We at the London Centre for Nanotechnology—a joint venture between University College London and Imperial College—are taking a bottom-up approach having decided that many of the ‘accepted dogmas’ of collagen biology may not be quite as soundly based as currently held. We are using several of the tools of ‘hard’ nanotechnology—such as atomic force microscopy—to re-examine collagen structure with the longer term aim of using such information to design materials with appropriate physical attributes. Examples of our current research on mineralised and soft tissue collagens are presented.     

Key factors and considerations in the assessment of international collaboration: a case study for Austria and six countries

This bibliometric study on the collaboration of Austria and six target countries (Slovenia, Hungary, Czech Republic, Denmark, Switzerland and Israel) reveals the importance of differentiation between the bilateral and multilateral contingents in the assessment of international scientific collaboration. For this purpose a “degree of bilaterality” (DB) and a “citation degree of bilaterality” (CDB) are introduced. In our findings the DB and the CDB have values lower than 1/3 and 1/5, respectively. Therefore, the total collaboration is mostly shaped in its volume and impact by the multilateral contingent. Regarding the impact estimation of the collaboration publication output, a multi-faceted approach was used. It is recommended to separately analyze the following three aspects: the un-cited range, the average range and the excellence range. Considering different country specific parameters the total number of publications and citations were resized for each type of collaboration and the results discussed. Only a very weak correlation between ‘times cited’ and the number of affiliations or authors was observed at publication level. Neither the number of authors or affiliations determines impact increase. Rather internationalisation and cooperation seem to be the crucial factors.     

Knowledge-based innovation and collaboration: a triple-helix approach in Saudi Arabia

This study analyzed the research productivity of Saudi academics using the triple-helix model. In the analysis, we combined domestic and international collaboration by three sectors—university, industry, and government—according to the model of the triple-helix. This approach produces better results than by simply including international collaboration as fourth sector. According to the analysis, research collaboration in Saudi Arabia which is measured by the triple-helix, was “-” uncertainty (negative T-value) while scientific productivity has been dramatically increasing since the late 2000s. The triple-helix collaboration does not quite differ between domestic collaboration and “domestic and international” collaborations. In our further analysis, we found that technological development was not based on scientific research in Saudi Arabia; rather, the technological development relies on prior technology (patent references). From that point, Saudi Arabia’s current long-term strategic plan to develop a scientific base for a knowledge-based industry is well aligned to the current contexts of Saudi Arabia.     

Does a country’s scientific ‘productivity’ depend critically on the number of country journals indexed?

In this paper, we examine the question whether it is meaningful to talk about the scientific productivity of nations based on indexes like the Science Citation Index or Scopus, when the journal set covered by them keeps changing with time. We hypothesize from the illustrative case of India’s declining productivity in the 1980s which correlated with a fall in its journals indexed, that an apparent increase/decrease in productivity for any country, based on observed change in its share of papers could, in fact, be an effect resulting from the inclusion of more/less journals from the country. To verify our hypothesis we have used SCIMAGO data. We found that for a set of 90 countries, the share of journals regressed on the share of papers gave a linear relationship that explained 80% of the variance. However, we also show that in the case of China’s unusual rise in world scientific productivity (to second rank crossing several other countries), there is yet another factor that needs to be taken into account. We define a new indicator—the JOURNAL PACKING DENSITY (JPD) or average number of papers in journals from a given country. We show that the packing density of Chinese journals has steadily increased over the last few years. Currently, Chinese journals have the highest ‘packing density’ in the world, almost twice the world average which is about 100 papers per journal per annum. The deviation of the JPD from the world average is another indicator which will affect so called ‘national productivities’ in addition to the number of national journals indexed. We conclude that in the context of a five fold increase in the number of journals indexed over 20 years, the simplistic notion of ‘scientific productivity’ as equivalent to papers indexed needs to be re-examined.     

Fluorine research in South Africa and four benchmarking countries: Comparative mapping and assessment

Fluorine research has been identified as a priority area in South Africa and the South African Nuclear Energy Corporation (NECSA) is embarking in an effort to expand its hydrogen fluoride and aluminium trifluoride production capacity. On the eve of those efforts this article reports the findings of an effort to map and assess fluorine research in South Africa in comparison to four other countries i.e. Malaysia, Australia, Germany and Italy. The results of the assessment are aimed at guiding future directions for fluorine research in the country, at identifying centres of expertise nationally where new research chairs could be established, at identifying international centres of expertise to be utilised for collaboration and of course for inter-temporal benchmarking of fluorine research in South Africa. South Africa is identified to be producing a small number of fluorine research publications in comparison to other countries like Germany and Italy which produce orders of magnitude larger number of publications and in comparison to country’s total research effort. Furthermore the relevant research effort appears to be dispersed geographically and in disciplinary terms. Relevant recommendations are provided with particular emphasis on the pluralistic science policy approach followed in the country.     

In-depth analysis on China’s international cooperation in science

It has been about 30 years since China adopted an open-up and reform policy for global competition and collaboration. This opening-up policy is accompanied by a spectacular growth of the country’s economy as well as visibility in the world’s scientific literature. Also China’ competitiveness in scientific research has grown, and is mirroring the development of the country’s economy. On the other hand, international collaboration of most countries dramatically increased during the last two decades and accompanied the growth of science in emerging economies. Thus the question arises of whether growth of competitiveness in research is accompanied by an intensification of collaboration in China as well. In the present study we analyse the dynamics and the national characteristics of China’s co-operation in a global context. We also study research profile and citation impact of international collaboration with respect to the corresponding domestic ‘standards’.     

Mapping of dental science research in India: a scientometric analysis of India’s research output, 1999–2008

The study examines India’s performance based on its publication output in dental sciences during 1999–2008, based on several parameters, including the country annual average growth rate, global publication share & rank among 25 most productive countries of the world, national publication output and impact in terms of average citations per paper, international collaboration output and share and contribution of major collaborative partners, contribution and impact of select top 25 Indian institutions and select top 15 most productive authors, patterns of communication in national and international journals and characteristics of its 45 high cited papers. The study uses 10 years (1999–2008) publications data in dental sciences of India and other countries drawn from Scopus international multidisciplinary bibliographical database.     

Bibliometric analysis of homeopathy research during the period of 1991 to 2003

Summary Homeopathy has been applied to clinical use since it was first presented 200 years ago. The use of the bibilometric analysis technique for examining this topic does not exist in the literature. The objective of this study is to conduct a bibliometric analysis of all homeopathy-related publications in Science Citation Index (SCI). A systematic search was performed using the SCI for publications during the period of 1991 to 2003. Selected documents included Homoeopathy, Homoeopathic, Homeopathy, or Homeopathic as a part of the title, abstract, or keywords. Analyzed parameters included authorship, patterns of international collaboration, journal, language, document type, research address, number of times cited, and reprint authors address. Citation analysis was mainly based on the impact factor as defined by the Journal Citation Reports (JCR) and on citations per publications (CPP), which is used to assess the impact relative to the entire field and is defined as the ratio between the average numbers of citations per publications in a certain period. Of total articles, 49% had a single author. The UK, the US, and Germany produced 71% of the total output, while European countries as a whole also contributed 65% of the total share of independent publications. English remains the dominant language, it comprised only 76%, while German contributed 18%, and the remaining where distributed among 8 European languages. More document types and languages, and fewer pages have appeared in homeopathy research. 3.5% of papers were cited more than 10 times in three years after publication, and 60% were never cited. Small-group collaboration was a popular method as co-authorship. The top 3 ranking countries of publication were the UK, the US, and Germany. The US dominated citation followed by the UK, and then Germany. In addition, a simulation model was applied to describe the relationship between the cumulative number of citations and the paper life.     

Knowledge production through collaborative research in sub-Saharan Africa: how much do countries contribute to each other’s knowledge output and citation impact?

This paper examines co-authorship of research articles in Thomson Reuters citation indexes in order to assess knowledge co-production in selected sub-Saharan African countries. Two indicators, namely publications and citations, were analysed to establish the patterns of knowledge co-production and its scientific impact, respectively. The study found that knowledge production through collaborative research among sub-Saharan African countries is minimal and contributes only a small percentage when compared to collaboration between sub-Saharan African countries and their foreign counterparts. Similarly, the scientific impact of international collaboration was higher than that of continental collaboration. Countries belonging to the same geographic region contributed to each other’s knowledge production more frequently than they did to the countries outside their region. It is recommended that, for knowledge co-production in sub-Saharan Africa to improve, various measures such as encouraging student and staff exchange, hosting more regional conferences and encouraging research networks need to be put in place.     

Black Africa in the science citation index

According to a quantitative analysis of the publications of the Black African Countries indexed in the SCI between 1992 to 1998, Nigeria seems to be the leader in scientific production on the black continent during that period (the term ‘Black Africa’ refers to all African countries excluding South Africa, Maghrebi, and Egypt). However, an analysis that only takes into account the number of publications does not necessarily disclose very much about neither the dynamics of the respective scientific community nor about the representativity of the country’s production with respect to its total population. Therefore, the number of publications per country is compared with the respective total population. According to this method, Kenya turns out to be the leader in scientific-publication production and several other countries get higher ranks. Additionally, any evaluation of scientific production in that part of the world should also take into account the specific features of these countries, e.g. the difficulties in publication and the existence of a large number of unpublished texts.     

Using online databases to form subject collections for informetric analyses

The online databases of the Dialog System retrieve only 26% of documents in an exhaustively compiled collection on the subject of Bradford's Law of Scattering, with some documents being retrieved from many databases. However, when the Exhaustive Collection is more stringently defined to include only those documents more about the subject, the retrieval rate of Dialog improves to 61%, while its most productive database, LISA, alone retrieves 37%. Both of these ‘samples’ give good estimates of the size-invariant properties of the Exhaustive Collection which are typically studied in Bradford and Growth Analyses—vindicating this use of online searching. However, without additional information, online searches are of little use in determining size-related properties of subject literature collections. Whether the analysis reported here—which relies on identical interpretations of a ‘subject’—has secure foundations is briefly considered.
