A multisynchronous obsolescence study has been performed on two computing journals that publish on technical aspects of computer system management (networks and operating systems). This area of computer science is found to have a relatively high obsolescence rate (a median citation rate of four years). This rate is similar to that of fields in engineering and the technology-dependent hard sciences.
Bibliographic data on ophthalmology, optometry and visual science (OOVS) literature of China drawn from the SCI-Expanded database
covering the period 2000–2007 (961 publications) were analyzed to create a comprehensive overview of research output. Of 961
articles, 480 were published in 2006 and 2007. The majority of researchers worked in university hospitals (53%). 21% of the
publications included one or more international co-authors. For each article, the average author number was 4.96±2.73, which
increased from 3.96 in 2000 to 5.36 in 2007. The most cited references came from Investigative Ophthalmology & Visual Science
and Ophthalmology. The greatest number of studies was focused on the retina.
This paper examines four historical accounts of the quantum mechanics problem in physics. The purpose is to describe the litrature used by the histories quantitatively using frequency of date of publication. Additionally, one of the histories was tested against the other three to determine differences. A Moments Test and a t Test were employed. The results indicated the literature history of quantum mechanics, when plotted as a function of frequency of publication date is non-normal, negatively skewed, and is platykurtic. The test for difference between the one history and the cumulative histories was non-significant. Interpretations of the results are discussed.
Data were compiled and linearly correlated on the growth in the gross domestic product (GDP) with the academic chemical engineering
literature over a recent 26-year period for five different English-speaking countries, namely, the United States, Canada,
Great Britain, India and Australia. The publication figures were also scaled to the total number of chemical engineering schools
in the country; furthermore, all of these data were normalized from zero to unity, using the figures for the most recent year
(1996) as the denominators, and then correlated against each other in linear fashion. Resulting confidence levels were in
excess of 99% for each of the individual five countries, as well as for the entire set of normalized data for all of the countries.
A bibliography of biochemical literature of Nigeria for the period, 1970–1984 containing a total of 500 items, was analysed to test the applicability of Lotka's law and 80/20-rule to the author productivity distribution patterns. Four different files were created out of the data on author productivity: one for the publication of all the authors, second for the publications by first authors only, third for single authors and fourth for the contributions of only coauthors. Lotka's law could apply in all the four cases with different values of . The Kolmogorov-Smirnov test was applied to test the applicability of Lotka's law at 0.01 level of significance. Egghe's theory and formula were used to test 80/20-rule and it was found that the rule did not apply to any of the four data sets.
The coincidence method proposed earlier by one of the authors is applied to rank distribution studies of the report literature of the International Nuclear Information System, INIS, and a two-level concept is used to discuss the results of the present and previously reported investigations. Transitions between macrolevel and microlevel of information for constant forms of communication as well as transitions between different forms of communication at constant levels are compared. Escape of the information avalanche for the highly specialized single scientist, greater efficiency of the report literature compared with journal literature in the field of nuclear research, non-compatibility of macrolevel and microlevel of information could be confirmed quantitatively. It is an open question how to transform microlevel distributions into macrolevel distributions.
Using the field of acid rain research as a case study, it was found that scientists who contribute to the popular literature are more likely than others to be called on to give Congressional testimony (and vice versa) and that the work of these same scientists is well recognized by their peers as judged by rates of citation. Indeed, scientists who contribute to the popular literature are more highly cited than those who do not whether or not they are called upon for expert testimony. Since those who give testimony are more highly cited than those who do not, some evidence also exists that scientists called before Congressional hearings are among those most influential in the science community.
The use of indicators based on the analysis of the scientific literature cited in patent documents is proposed for the evaluation
of biomedical research. A study carried out on several groups of researchers working in universities, public research centers,
and hospitals, has shown that an important percentage of Spanish scientists have authored publications that are cited in US
patents in the field of Biotechnology. The study and analysis of those cites allows a evaluation of the flow of knowledge
generated by the different groups of scientists towards the development of technologies, and to learn on the relationship
between the characteristics of the cited publications and the frequency they are cited in the patents. The results obtained
avail the use of new indicators based on the cites in patents to perform a more complete evaluation of the published research
related with Biotechnology and Biomedicine, both at the level of research institutions and individual scientists.

This paper shows how Database Tomgraphy can be used to derive technical intelligence from the published literature. Database
Tomography is a patented system for analyzing large amounts of textual computerized material. It includes algorithms for extracting
multi-word phrase frequencies and performing phrase proximity analyses. Phrase frequency analysis provides the pervasive themes
of a database, and the phrase proximity analysis provides the relationships among the pervasive themes, and between the pervasive
themes and sub-themes. One potential application of Database Tomography is to obtain the thrusts and interrelationships of
a technical field from papers published in the literature within that field. This paper provides applications of Database
Tomography to analyses of both the non-technical field of Research Impact Assessment (RIA) and the technical field of Chemistry.
A database of relevant RIA articles was analyzed to produce characteristics and key features of the RIA field. The recent
prolific RIA authors, the journals prolific in RIA papers, the prolific institutions in RIA, the prolific keywords specified
by the authors, and the authors whose works are cited most prolifically as well as the particular papers/journals/institutions
cited most prolifically, are identified. The pervasive themes of RIA are identified through multi-word phrase of the database.
A phrase proximity analysis of the database shows the relationships among the pervasive themes, and the relationships between
the pervasive themes and subthemes. A similar process was applied to Chemistry, with the exception that the database was limited
to one year's issues of the Journal of the American Chemical Society. Wherever possible, the RIA and Chemistry results were
compared. Finally, the conceptual use of Database Tomography to help identify promising research directions was discussed.
From an analysis of bibliographic data on 430 journal articles on liquid crystals covered inPhysics Abstracts 1976 and the 4729 citations to them up to the end of 1987, we have identified the geographic origin, the prominent institutions, language and journal-wise distribution of the papers, the citedness of these papers, and the distribution of citations as a time series for the highly cited papers. We have also analysed the 126 papers published by authors from India, Canada, Australia, Israel, Japan and the United Kingdom and covered inPhysics Abstracts 1978, and the 1154 citations to them up to 1987. Unlike in most other high tech areas of physics, in LC research the difference in performance between the USA and the other leading countries is not very pronounced. Publication data from 1976, 1978 and 1985 reveal that LC literature is on the rise and that the percentage share of the Soviet Union is rising fast and that of the USA is on the decline.
