This study is an attempt in the direction of applying Bibliometric analysis to investigation the
extent of research outputs, activities, nature, current trend and direction of research. The
study analyse entirely 2309 research output of Haramaya University staff, research scholars
and post graduate students that have been indexed in Haramaya University Electronic Thesis
and Dissertation repository ranging from the year 1981 to 2016. Bibliometric studies were
used to identify, relative growth rate, exponential growth rate, authorship pattern,
collaborative measures, author’s productivity, doubling time, time series analysis of single
authorship trend most prolific department, most prolific region and relative research effort.
The laws of Lotka have also been tested. The results indicate that the year wise distribution of
total research output has an annual average growth rate of 0.25. Out of 2309 research
outputs contribution 70.12 % have been contributed by single authors, followed by
contribution made by three authors 25.12 %, two authors 6.79 % and four authors 0.42 %
respectively. A total of 3553 authors contributed 2309 research outputs during the study
period with an average of 1.9 authors per paper and 0.4 paper per authors. The laws of Lotka
was applied in Haramaya University research output during the period under study and
found that Lotka’s law was not applicable to this data. Average degree of collaboration was
found 0.3, which also indicated dominance of single author’s research. The relative growth
rate and doubling time of research outputs have shown increasing trend. It is also found that
the annual average exponential growth rate was 1.08.The most favoured department among
the research community of Haramaya University are Plant science, followed by Animal and
Range science, Agricultural economics. The future trend of growth in single authored
research output may take a decreasing trend during the year to come. The highest research
effort was made in the year 1997 and 2009 with 1.55 PEI and the lowest research effort was
made in the year 2011 with 0.62 PEI. The regional distribution of Haramaya university
research output reveals the most researched region among the research community is
Oromia, Amhara, and SNNPR. It is therefore recommended that, in the present study
Collaboration is studied only as it relates to joint authorship. A broader view of collaboration
can be studied by other researchers that includes inter disciplinary collaboration, local and
foreign collaboration activities among authors by country and institution |
