The contribution of Turkish researchers to positive sciences is increasing. Turkish scientists published more than 5100 articles in 1998 in scientific journals indexed by the Institute for Scientific Information's Science Citation Index, which elevated Turkey to the 25th place in the world rankings in terms of total contribution to science. In this paper, we report the preliminary findings of the bibliometric characteristics (authors and affiliations, medical journals and their impact factors, among others) of a total of 8442 articles published between 1988 and 1997 by scientists affiliated with Turkish institutions and indexed in the MEDLINE database.
An analysis of 4650 publications abstracted inJournal of Current Laser Abstracts Vol. 27 (April 1990-March 1991) indicates that 14 countries contributed about 94% of the research output with USA toping
the list followed by Japan and the erstwhile USSR. Technical reports and patents, besides articles in scientific journals
constitute an important source of information on laser science and technology. “Spectroscopy of laser output” is the sub-speciality
which has received maximum emphasis. USA has paid almost equal emphasis for theoretical, experimental and applications of
laser research, while such pattern is not applicable for other countries. For USSR, China, and India, the impact of research
did not commensurate with the publication effort.
In this paper we compare the scientific research in the semiconductor-related field in China with some other major nations
in Asia. It is based on the bibliometric information from SCI-Expanded database during the time period of 1995–2004. We show
that China has been developing fast in semiconductor research, and become the second productive country in Asia as reflected
by the publication profile. The evidences indicate a significant increasing trend in the research efforts and readership among
Asian countries. Similar to the scientists in Japan and South Korea, Chinese scientists were more inclined to work in larger
groups, typically 4 or more authors. The assessment of research quality is further conducted based on citation-based measures.
As benchmarks, two western countries, namely USA and Germany, have been compared in the citation analysis. It is revealed
that the impacts of research outputs in the Asian countries, except for Japan, have been badly incommensurate with their devoted
research efforts compared with USA and Germany. Like most of other Asian countries the research results of Chinese scientists
in semiconductor have a low international visibility despite their strong research efforts and increasingly large domestic
readership. The application of Leimkuhler curve illustrates vividly the inequality of citation times among the compared countries.
Furthermore, the Gini Indices of each country and each pair of countries are calculated which illustrates again the inequality
of informetric productivities.
Applied and basic approaches to scientific inquiry were compared through a bibliometric analysis of two Canadian journals in plant biology. No differences were found between the journals in the distribution of citations across different sections of research articles (that is, Introduction, Methods, Results, and Discussion). Moreover, no contrasts were found in the frequency of multiple authorships or in the age distribution of cited works. However, the journals differed significantly on three other bibliometric measures: author affiliation, number of references per article, and publication format of cited works.
This article presents an exploratory analysis of publication delays in the science field. Publication delay is defined as
the time period between submission and publication of an article for a scientific journal. We obtained a first indication
that these delays are longer with regard to journals in the fields of mathematics and technical sciences than they are in
other fields of science. We suggest the use of data on publication delays in the analysis of the effects of electronic publishing
on reference/citation patterns. A preliminary analysis on a small sample suggests that—under rather strict assumptions—the
cited half-life of references may be reduced with a factor of about 2 if publication delays decrease radically.
This study analyzed 2443 papers published in 2006 by European Union authors on pain-related research. Five EU countries (the
UK, Germany, Italy, the Netherlands and France) each published > 200 papers while three countries (Cyprus, Malta and Estonia)
published none; socio-economic indicators were related to each country’s productivity. The 2443 papers were published in 592
journals and Cephalalgia, Pain and European Journal of Pain were the most prolific. Publications were also analyzed for intra- versus inter-EU/non-EU collaborations and subdisciplines
profiles in Clinical Medicine and the Life Sciences for the World, USA, EU and the top-four EU countries were compared.
