Large Hadron Collider

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator complex, intended to collide opposing beams of protons (one type of hadron) charged with high energy. Its main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. It is theorized that the collider will confirm the existence of the Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model, and could explain how other elementary particles acquire properties such as mass.

The LHC was built by the European Organization for Nuclear Research (CERN), and lies underneath the Franco-Swiss border near Geneva, Switzerland. It is funded by and built in collaboration with over eight thousand physicists from over eighty-five countries as well as hundreds of universities and laboratories. The LHC is already operational and is presently in the process of being prepared for collisions. The first beams were circulated through the collider on 10 September 2008, and the first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October.

Bibliometrics and Social Work A Two-Edged Sword Can Still Be a Blunt Instrument

In order to improve the productivity and impact of social work scholarship, the profession must look beyond bibliometrics to other issues that must be considered. These include the lag time between acceptance and publication of articles, the quality of peer review experienced by social work authors, and the overabundance of journals being published in social work.

Citation Analysis of Chemistry Doctoral

A citation analysis of dissertations accepted in the Department of Chemistry at The Ohio State University between 1996-2000 was performed as a way to determine material use. The 30 dissertations studied generated a total of 3,704 citations. Types of materials cited, currency of literature, and dissertation topics were all analyzed.

The current results corroborate past research by other authors. Journal articles were cited more frequently than monographs: 85.8% of the citations were journal articles and 8.4% of the citations were monographs. The results of this study may be used to assist OSU and other universities in chemistry collection development.

A Concise Introduction to Bibliometrics & its History

The origin of the term "Bibliometrics"

The terms bibliometrics and scientometrics have been introduced almost simultaneously by Pritchard and by Nalimov and Mulchenko in 1969. While Pritchard explained the term bibliometrics as "the application of mathematical and statistical methods to books and other media of communication" (Pritchard, 1969), Nalimov and Mulchenko defined scientometrics as "the application of those quantitative methods which are dealing with the analysis of science viewed as an information process" (Nalimov and Mulchenko, 1969). According to these interpretations, scientometrics is restricted to the measurement of science communication, whereas bibliometrics is designed to deal with more general information processes.

The anyhow fuzzy borderlines between the two specialities almost vanished during the last three decades, and nowadays both terms are used almost as synonyms. Instead, the field informetrics took the place of the originally broader speciality bibliometrics. The term informetrics was adopted by VINITI (Gorkova, 1988) and stands for a more general subfield of information science dealing with mathematical-statistical analysis of communication processes in science. In contrast to the original definition of bibliometrics, informetrics also deals with electronic media and thus includes topics such as the statistical analysis of the (scientific) text and hypertext systems, library circulations, information measures in electronic libraries, models for Information Production Processes and quantitative aspects of information retrieval as well. In his review entitled "Biblio-, sciento-, infor-metrics??? What are we talking about" Brookes (1990) gave an interesting overview about origin and contexts of these metrics of science, literature and information in general. The description given by Glänzel and Schoepflin in 1994 defines the scope of bibliometric research areas is much wider than the usual ones, and thus integrate all presently existing orientations such as applications to science policy, library science, and information retrieval. According to their approach, bibliometrics and informetrics include "all quantitative aspects and models of science communication, storage, dissemination and retrieval of scientific information". The definition by Gloria Carrizo-Sainero (2000) considers bibliometrics "the ensemble of methodological knowledge that will serve the application of quantitative techniques in order to evaluate the processes of production, communication and use of scientific information. Its goal is to contribute to the analysis and evaluation of science and research." This gives a clear orientation in direction toward research evaluation that has become the most important application of bibliometric research and technology.

From the above-mentioned general description of the main task of the research field bibliometrics (scientometrics), the following statement becomes quite obvious. Bibliometrics can be used to develop and provide tools to be applied to research evaluation but is not designed to evaluate research results. Moreover, bibliometrics does not aim at replacing qualitative methods by quantitative approaches and bibliometrics is not designed to override or even to substitute peer reviews or evaluation by experts but qualitative and quantitative methods in science studies should complement each other.

Bibliometrics of Alkaloid Chemistry Research in India

This paper attempts at quantitative and qualitative assessment of alkaloid chemistry (a subgroup of organic chemistry) research in India as viewed through Chemical Abstracts. While focusing on World output vis-a-vis Indian output in terms of publications, this paper identifies the centers of excellence of alkaloid chemistry research, the research groups involved, and their channels of communication, besides studying the citedness of Indian work. Alkaloid chemistry research performed in India is found to be fairly collaborative and part of main stream science.

Bibliometrics of electronic journals in information science

The bibliometric characteristics of electronic journals (e-journals) covering the field of information science have been studied. Twenty-eight e-journals were identified and ranked by number of articles on the subject they published. A Bradford plot revealed that the core is not well developed yet, but it will likely contain six journals. The publication of information science articles in e-journals began about 1990. In 1995 (the starting date for this study), a modest 26 articles appeared, but publication has now risen to approximately 250 articles per year. The most prolific authors are identified. The vast majority of them are located in the United States or United Kingdom. Only 26 articles have authors from more than one country, showing that electronic technology has not yet strongly influenced international collaboration. About 2/3 of the articles originate in academic institutions. Common topics of e-journal articles in information science include electronic information, electronic publishing, virtual (digital) libraries, information search and retrieval, and use of the Internet. Seven online databases cover these e-journals; Information Science Abstracts is the only one to cover all 28 journals, and it has the highest number of abstracts from them - over 1,100.

Cybermetrics

An Electronic-only Journal and a Virtual Forum (The Journal) devoted to the study of the quantitative analysis of scholarly and scientific communications in the Internet. It is open to world-wide researchers to publish and discuss their findings. Internet offers them new and increased capabilities to distribute their results to a greater audience.

From 1997 the editors are organizing a series of conferences (The Seminars) on a yearly basis (Cybermetrics'XX) to disseminate results from quantitative analysis of the Internet. These events intend to show preliminary results and new methods and they are organized simultaneously with large International Congresses.

Cybermetrics also maintains a series of directories of electronic resources (The Source), including secondary archives of interesting web papers in pdf format. The aim is to provide a reference tool to those researchers involved in the quantitative description and analysis of the Internet as a scholarly communication tool. It is also intended to add original data as a source or reference for larger studies, specially including figures about the distribution and evolution of R&D contents in the World Wide Web.

Bibliometrics - Recognising Trends in Science

The Central Library offers the institutes at Research Centre Jülich and external customers the opportunity of having their publications analysed statistically in order to show the reception of their scientific work by the specialist community.

Bibliometrics - what for?
Bibliometric analyses are an instrument that documents the publication performance of authors and institutions as well as their response, in terms of the number of citations they receive. They provide information on how the specialist community perceives publications by a research group or an institute.
