This paper examines selected hard sciences research output in South African universities with special reference to the dispersion of research performance within and between universities as a potential indicator of competitiveness in higher education systems. The subject fields surveyed are Physics, Chemistry, Biology, civil engineering and architecture, Earth sciences, Mathematics, Computer Science and Medicine in seven top universities. The study endeavours to see if these top institutions present levels of concentration of performance within universities that are high or very high and greater than that between them. We investigate the level of correlation between performance in research and its dispersion in the universities. The field of observation is made up of all the South African universities active in the hard sciences. Research performance is evaluated using bibliometric analysis, through publication indexed in the Web of science between the years 2005 and 2013. Relevant data for the study was downloaded from web of Science using largely Science Citation Index (SCI) but also Social Sciences Citation Index (SSCI) and Arts and Humanities Citation Index (AHCI). From several bibliometric indicators of research performance evaluation (such as publication output, trend, citation analysis, impact factor and Hirsch Index), we used publication output by the scientists. The citation count and impact were used to indicate the research output and performance of researchers and what differentiates them from others. We observe that the South African education system presents levels of concentration of performance within universities that are high and at times greater than that between them. This situation to a certain extent allows the search for a competitive advantage with the resulting production of outstanding research institutions, which are capable of attracting and retaining the top scientists both nationally and internationally. This in a way brings about dispersion of performance and indicates the intensity of competitiveness in research institutions and universities. We also notice that in the competitive system, the variability of performance within is much less compared to between universities. The results of the research shows that two universities with the same average research performance could have altogether different impacts on national economic development. As far as competitive systems are concerned, dispersion of performance within universities is so high that it is very difficult to perceive strong differences in performances between universities. The results obtained can be used as indicators for policy making and examine the effectiveness of selective funding of universities based on national research assessment exercises.

Abstract Mendeley is a citation management tool and widely used by academics, educators and librarians around the world. It gives early impact data in relation to an individual academic’s work, rather than citation data. The study reported in this paper aimed to investigate and characterize the presence of DESIDOC Journal of Library & Information Technology articles in Mendeley. Data were exported... Mendeley is a citation management tool and widely used by academics, educators and librarians around the world. It gives early impact data in relation to an individual academic’s work, rather than citation data. The study reported in this paper aimed to investigate and characterize the presence of DESIDOC Journal of Library & Information Technology articles in Mendeley. Data were exported from Mendeley using Webometric Analyst software. A total 391 articles were found with total 6132 readership count.The results show that student and librarian groups are primary readers of the publications as compared to faculty, researchers, and other reader groups. There is a 0.3217 correlation between Scopus citations with Mendeley readers. It was also noted that all the 391 articles has at least one reader. Read More Read Less

Abstract Carrying out study on talent group composition can help us insight its present situation, and discover its potential problem, such as population aging, knowledge flow barrier, inbreeding, etc. An analysis model is proposed to characterize the talent group composition of research institute in three dimensions: age distribution, education experiences and collaboration pattern. Moreover, the analysis is based on objective data,... Carrying out study on talent group composition can help us insight its present situation, and discover its potential problem, such as population aging, knowledge flow barrier, inbreeding, etc. An analysis model is proposed to characterize the talent group composition of research institute in three dimensions: age distribution, education experiences and collaboration pattern. Moreover, the analysis is based on objective data, and objective indicators. Age distribution may reflect the population aging problem whether or not; education experiences may reflect the in breeding problems; while collaboration pattern may reflect the knowledge flow problems. According to the indicator of each dimension, research institutes are divided into different types, the classification reveals different problems they may have. At last, an empirical study was conducted on two research institutes to prove the effectiveness of this model. Read More Read Less

Background: Irritable bowel syndrome is a functional gastrointestinal disorder characterized by changes in bowel habits and abdominal pain without any organic cause. The process of disseminating knowledge among the science and specialized fields of knowledge is one of the major issues affecting the optimal development of knowledge in each field. Moreover, the understanding of the Infrastructure is necessary and influential to form specialized knowledge. Aims: This study aims to analyze the articles regarding IBS disease based on the concepts of co-occurrence network analysis and centrality indicators published in Clarivate Analytics WoS1 during 1983-2017. Methods: This is a descriptive study, using Scientometric techniques. Its statistical population contains all clinical trials related to IBS disease in Clarivate Analytics WoS during 1983-2017. Results: The scientific research on IBS disease starts in 2014. Based on the scientific map of countries, IBS disease has been active in some countries including Australia, Scotland, Austria, Poland, Ireland, Hungary, and England. USA and China have also been active in research on this disease from 2015. The top authors in IBS field in Clarivate Analytics WoS during 1989- 2017 are Siemren, Mayer, Camillier, Tornblom and Santos. Conclusions: The analysis of IBS disease also showed that based on co-word analysis there are 11 clusters. Among those clusters, 1 is the largest and related to diarrhea-predominant IBS (IBS-D). Other clusters are IBS- related stress, disruption of intestinal flora, bacteria, secretion of endocrine cells, infection with Blastocystis, gastrointestinal disorders under the effects of brain damage, genetic effects, melatonin, and the role of probiotics which play an important role in the emergence of various types of IBS.
