Bibliometric technique of citation analysis was applied to the data of five psychological periodical literature. The distribution
of citations frequencies was statistically tested and the obsolescence factors were determined. The relation between the growth
and obsolescence has been studied, and it has been observed that “higher the growth of literature, higher the obsolescence
as well as higher the half life.”
The paper provides a picture of Mexican health sciences research for the years 1982–1986, measuring, bibliometrically, the size of its scientific activity. The most widely bibliometric indicators for research evaluation, publication count and citation analysis, are combined to determine the degree of production, productivity, and impact. The study also highlights the role of leading research institutions.
This study used citation analysis method to identify the 40 classics published in the Journal of the American Society for Information Science and Technology from 1956 to 2007. Yhe year and subject distributions of these classic references reflect the history and the current status
of information science.
This study quantitatively reviews the empirical studies of negative political advertising. A method of the combination of citation analysis and content analysis is used. The citation analysis examines each cited work in 20 selected studies with respect to its citation information; and the content analysis investigates these 20 selected studies (citing sources) in terms of their hypotheses, research questions, and methodologies. The aggregated information from the individual cited works and the citing works show that scholars from communication and other disciplines have strong influence on the development of the empirical studies on negative political ads, but communication scholars remain as the driving force. Facing continuously increased literatures in the area, communication scholars need to develop a theory or theories to guide the research. The direction of the research has been moving toward focusing on the boarder and more general effects of negative political ads.
Based on the premise that citations in scientific journals can tell us a lot about the journals, we have compared Indian journals in the fields of astronomy, physics, chemistry, biochemistry, geology and ecology with leading world journals. The two criteria compared are the age of references and the journals often cited in each of the journals considered. Our results show that although overall Indian science is mediocre, parts of India's scientific enterprise are cognitively better related to world science. The peripherality is not uniform across the board, but some areas like astronomy and to some extent physics are closer to the central or mainstream science than others. Although citation analysis is not normally used for cross-field comparisons, this paper demonstrates that, if used judiciously, citation analysis can yield valuable insights into issues involving many fields.
The main purposes of this article are to uncover interesting features in real-world citationnetworks, and to highlight important substructures. In particular, it applies lattice theory tocitation analysis. On the applied side, it shows that lattice substructures exist in real-word citationnetworks. It is further shown that, through its relations with co-citations and bibliographiccoupling, the diamond (a four-element lattice) is a basic structural element in citation analysis.Finally, citation compactness is calculated for the four- and five element lattices.
The aim of this article is to demonstrate on the scientific field "economics" the search for fundamental articles.Co-word analysis and co-citation analysis enable to visualize the structure of a scientific field on the maps of science. Then we can find the fundamental themes on the maps. After finding the articles belonging to these fundamental themes we can discuss the fundamentality of the formers, too.
In this article we study directed, acyclic graphs. We introduce the head and tail order relations and study some of their
properties. Recalling the notions of generalized bibliographic coupling and generalized co-citation, and introducing a new
property, called the l - property, we come to a characterization of lattices. As document citation networks are concrete realizations of directed
acyclic graphs all our results are directly applicable to citation analysis.
The method of co-citation analysis is used to build citation networks in information science. As data base the first 13 volumes (1961–1973) of the leading Soviet journal in the field (Nauchno-tekhnicheskaya Informatsiya) were used. The results reveal the topical structure of information science, the communities of authors and the names of single leading scientists. The evaluation of scientists' work is based on two measures: productivity (with or without co-authorship) and popularity (popularity of authors and popularity of papers).
