INTRODUCTION

Individual scientists including the Nobel laureates are more and more becoming the focus of scientometric studies for quite some time.(Kalyane, V.

Scientometrics is concerned with the quantitative features and characteristics of science and scientific research.

BIOGRAPHICAL SKETCH

Jeffrey C. Hall, (born May 3, 1945, Brooklyn, New York) is well known American geneticist for his investigations of courtship behaviour and biological rhythms in the fruit fly Drosophila melanogaster. His research into molecular mechanisms underlying biological rhythm in the fruit fly helped scientists gain new insight into circadian rhythm, the self-regulating 24-hour biological clock that drives daily behavioral patterns in humans and other animals. For his research, he was awarded with the Nobel Prize in Physiology or Medicine in 2017 (shared with American scientists Michael Rosbash and Michael W. Young).

Hall grew up in Washington, D.C. He attended Amherst College in Massachusetts with studying medicine. Hall studied genetics at the University of Washington in Seattle, where he received Ph.D. in 1971. He subsequently pursued his postdoctoral research at the California Institute of Technology (CIT). In 1974 Hall became an assistant professor of biology at Brandeis University in Waltham, Massachusetts.

In 2004, after being named Emeritus Professor of Biology at Brandeis, Hall joined University of Maine as an associate professor, later he became Libra Professor of Neurogenetics. In addition to the Nobel Prize, Hall was awarded with various awards and honours during his career, including the Gruber Prize in Neuroscience (2009) and the Canada Gairdner International Award (2012), both are shared with Rosbash and Young.

SCOPE OF THE STUDY

The study is covered the Jeffrey C. Hall's 201 publications (1972-2008) and citations received (1972-2017).

OBJECTIVES OF THE STUDY

The main objectives of the study are:

* To find out the year-wise and age-wise distribution of authorship pattern;

* Decade-Wise Distribution of Publication of Jeffrey C. Hall;

* To know the most citied papers;

* To know the year-wise citations;

* To find out the Journals preferred by Jeffrey C. Hall; and

* To identify the prominent authors.

METHODOLOGY

To conduct the study Scopus database was used to retrieve research output Jeffrey C. Hall. A total of 201 paper published by Jeffrey C. Hall during 1972-2017. The data obtained for study from Scopus database on November 10, 2017 and then transferred into spread sheet application and analysed as per objectives of the study.

RESULTS AND DISCUSSION

YEAR-WISE AND AGE-WISE PUBLICATION PRODUCTIVITY OF JEFFREY C. HALL.

Jeffery C. Hall's first paper was reported in 1972 at the age of 27 in Genetics. He subsequently published 200 papers in various journals during 1973-2017. Categories of his publications published includes 166 Journal articles (82.6%), 16 Reviews (8.0%), 7 Erratum (3.5%), 4 Conference papers (2.0%), 4 Short Survey (2.0%), 2 Notes (1.0%), 1 Editorial (0.5%) and 1 Letter (0.5%). Table 1 indicates authorship pattern; it reveals highest number of literature is written by two authored 43(21.39%), followed by three authored and five authored 34(16.91%). Table 1 also indicate that scientist has published 22 single authored and 179 multiauthored papers. At biological age of scientist 46 and 55 his publications productivity was on peak (14) and the Collaboration Coefficient is 0.89.

DECADE-WISE DISTRIBUTION OF PUBLICATION OF JEFFREY C. HALL

Table 1a. Indicates decade-wise distribution of publication of scientist, the maximum number of publications of scientist were published in decades III (1990-1999), followed by decades II (1980-1989) and IV (2000-2009). He published very less papers in decades I (1980s).

Figure 1 revealed highest number of publications 81(40.30%) of J. C. Hall were published in Decade III (1990-1999) and no paper was published after decade IV (2000-2009), scientist last paper was published in 2008 (indicated in Table 1) at age 63, it might be age factor to decline in productivity of publication.
