ACADEMIC PERFORMANCE OF BHARATHIDASAN UNIVERSITY:

MEASURING THROUGH SCIENTOMETRICS TECHNIQUES

INTRODUCTION

The present study attempts to assess the research performance of Bharathidasan University faculties and researchers from various department publication output. Evaluation of academic quality, productivity and performance has a key role on academic improvement of any academic unit such as an academician, group of academicians, department, institution or country.

The studies on academic quality evaluation have led to emergence of new fields and terminologies. Bibliometrics, Scientometrics and Informetrics have been started to take place in the literature and with the developments in web technologies web based metrics have also been introduced.

Scientometrics is a discipline which analyses scientific publications to explore the Structure and growth of science. The bibliometric / scientometric / informetric techniques used to analyze various quantitative or qualitative aspects of a publication.

It is a scientific field that studies the evolution of science through some quantitative measures of scientific information, as the number of scientific articles published in a given period of time, their citation impact, etc.

SCIENTOMETRICS

STATEMENT OF THE PROBLEM

The present study aims at analysing the research output performance of Bharathidasan University academic perspective. The last thirty years have observed an overwhelming quantity of publications addressing in various discipline. Due to scattered publications, the findings of this research have not been visible to the policy makers. In order to overcome this problem, this study attempts to convert the publications into a comprehensive database. This database covers information relating to the titles, authors, author affiliations, methodology adopted and the journals and highly referred articles coverage of the publications during the study periods of 1982 to 2011.

OBJECTIVES OF THE STUDY

To identify year wise growth rate of Bharathidasan university research output during 1982 to 2012.

To analyse the relative growth rate, doubling time and exponential growth rate

To find out the which type of communication channels are contributes bring out research literature

To identify the collaborative universities and states with Bharathidasan University research output

To apprehend and test the applicability of Bradford’s law of scattering of journals;

To find out the prolific authors contributes of research output on Bharathidasan University.

METHODOLOGY

A sample of 2507 articles during 1982 to 2012 published from Bharathidasan University and indexed in Scopus database, a proprietary product of Elsevier is used for the study. The database was used during 23rd March 2012 for study.

In order to perform a quantitative analysis, this study considered published articles in Scopus database. Publications classified as articles, conference paper, editorial material, letter and note etc. were also considered for the study. So, at the time of searching the database the search option was selected to “Bharathidasan University” only.

After searching, all the records were imported to MS Excel file, analyzed and tabulated for making observations. And to calculate the degree of author’s collaboration, the mathematical formula proposed by Subramanyam in 1983 is used.

The researcher has adopted the random stratified sampling method literature from Bharathidasan University as a representative of the present study.

2507 articles were downloading from the scopus database during period of 1982 to 2012 on 23rd March 2012.

For collection data used only the Scopus database during time span is 1982 to 2012 (thirty one years). The search string is “Bharathidasan University” was used for getting data. A total of 2507 records were downloaded and analyzed by using the Ms excel software application as per the objectives of the study.

SOURCE WISE ANALYSIS

Research output under various subjects

The BDU publications further grouped based on subject wise are identified Highest number of publications (more than 500) contributed to 3 domains: Physics and Astronomy (761), Biochemistry, Genetics and Molecular Biology (731) and Chemistry (613).

The top three subject fields receive more than 80 percents of publications. Followed by Agricultural and Biological Sciences (418), Mathematics (276), Materials Science (246), Environmental Science and Medicine (168), Pharmacology, Toxicology and Pharmaceutics (151), Chemical Engineering (138), Immunology and Microbiology (135), Engineering (129) and Computer Science has 103 publications.

The remaining departments are having below 100 publications. Hence, most of the publication applications can be seen in Physics, Molecular Biology and Chemistry.

The application has also spread into other disciplines too. In the near future Nanotechnology will exist has separate subject.

CONCLUSION

Due to technological importance and expected academic performance activity, BDU faculty research output has been intensively investigated by scientometric methods.

In this study, the current status has been presented. Initially occurrence and percentile method have been evolved chronologically. The progress has further been measured using growth rate and Dt. In the present decade (2002 to 2012) the Dt of BDU literature RGR is 0.29 and

doubling value is 7.28 years. Collaborative measured showed that the multi-authored contribution is high. It is even unsafe, because it strengthens the opinion of administrators and

politicians that scientific performance can be expressed simply by one note. Hence we always stress that a reliable set of several indicators is necessary, in

order to explicate different aspects of performance. Thus to evaluate the author collaboration, Collaborative Index and Degrees of

Collaboration were employed to prove that the more than 97 % of the research outputs are of collaborative in nature.
