With more than six million scientists who have published at least five papers, a list of Stanford University placed eighteen researchers from the UFS in the elite group of most cited scientists in various disciplines.

Eighteen scientists from the University of the Free State (UFS) have been named on a global list of leading scientists by Stanford University in the United States. The list is the result of a study published in PLOS Biology, a peer-reviewed open-access journal. The study is titled: A standardised citation metrics author database annotated for scientific field.

With more than six million scientists who have published at least five papers, the list placed the UFS researchers in the elite group of most cited scientists in various disciplines. Five hundred and ninety researchers from South Africa appear on the single year list and 536 researchers on the career list. 

Prof Corli Witthuhn, UFS Vice-Rector: Research, congratulated this group of outstanding researchers who make a rich contribution to building the research reputation of the UFS. “Their outstanding achievements impact our national and international standing, and ultimately global university rankings,” she said. 

She also expressed her hope that the researchers from mainly the natural, as well as the health sciences, will inspire and mentor younger colleagues to reach the same level of research success.

Citation metrics used and misused

The Stanford University scientists believe that citation metrics are widely used and misused. With this publicly available database, the authors of the article, led by Prof John Ioannides, strived to allow for a more transparent, comparable, and less error-prone approach to citation metrics. They introduced a new way of ranking scientists according to citations and other metrics but steered away from practices such as self-citations and citation farms where groups of authors cited each other’s papers. 

Citation metrics show how often scientists formally reference research outputs of other researchers in the footnotes of their own papers. 

Included in the database are the top hundred thousand scientists across 22 scientific fields and 176 subfields. Eight from the UFS are among the top 100 000 scientists in the world (according to data on both the single year and the career lists).

Citation data of more than 23 years

According to the research paper on this study, standardised information on citations, h-index, co-authorship, and citations of papers in different authorship positions are included in the database. Scopus citation data of more than 23 years were used to compile the database in the study. 

The single-year data set includes the following names of UFS researchers:

• Prof Abdon Atangana, Applied Mathematics
• Prof Melanie Walker, Education
• Prof Hendrik Swart, Applied Physics
• Prof J Hölsä, Applied Physics
• Prof Johan Grobbelaar, Marine Biology and Hydrobiology
• Prof A Chapagain, Environmental Engineering
• Prof Louis Scott, Palaeontology
• Prof Muhammad Altaf Khan, Applied Mathematics
• Prof Jeanet Conradie, Inorganic and Nuclear Chemistry
• Prof FB Dejene, Applied Physics
• Prof Robert Schall, Pharmacology and Pharmacy
• Prof RE Kroon, Applied Physics
• Prof Michael D MacNeil, Dairy and Animal Science

In the single-year data set, four of the thirteen scientists were listed in the Applied Physics field. Prof Swart, who is heading the SARChI Research Chair in Solid State Luminescent and Advanced Materials at the UFS, said being on the list of leading researchers is one of the cherries on the cake of a lifetime of research outputs. He said it is good that there is finally a scientific list of the world’s best scientists. 

The career-long data set includes the names of:

• Prof Abdon Atangana, Applied Mathematics
• Prof Louis Scott, Palaeontology
• Prof J Hölsä, Applied Physics
• Prof Johan Grobbelaar, Marine Biology and Hydrobiology
• Prof Robert Schall, Pharmacology and Pharmacy
• Prof HA Snyman, Ecology
• Prof Robert Frater, Respiratory System
• Prof Melanie Walker, Education
• Prof Johan Visser, Geology
• Prof Hendrik Swart, Applied Physics
• Prof James du Preez, Biotechnology
• Prof Michael D MacNeil, Dairy and Animal Science
• Prof Jeanet Conradie, Inorganic and Nuclear Chemistry
• Prof David Roux, General Chemistry

Data annually updated

The authors stated that whole-career metrics place young scientists at a disadvantage. They believe that single-year metrics remove much of this problem, “although again, younger scientists have fewer years of publication history and thus probably fewer papers that can be cited”, they said.

The authors of the Stanford study stated that a citation database is most useful when it can be

DF Malherbe Memorial Lecture

DF Malherbe Memorial Lecture: Language and language activism in a time of transformation (summary)
Proff Hennie van Coller and Jaap Steyn

Language activism necessary for multilingualism
The awareness is growing that language activism will be needed to bring about a truly democratic multi-lingual society. What is quite clear is that a firm resolve must continuously resist the concentrated pressure on Afrikaans-medium schools (and universities) to allow themselves to be anglicised through becoming first parallel medium, then dual medium, and finally English medium institutions.

Proff Hennie van Coller and Jaap Steyn said this last night (Wednesday night) in the 24th DF Malherbe Memorial Lecture at the University of the Free State. Prof van Coller is head of the Department Afrikaans, Dutch, German and French at the UFS. Both are widely honoured for their contributions to Afrikaans and the promotion of Afrikaans.

They discussed three periods of transformation since 1902, and said about the current phase, which started in 1994:  “Besides all institutions and councils having to be representative of South Africa’s racial composition, places of education were required to open their doors. Quite rapidly this policy has had the result that schools and universities may be solely English medium, but not solely Afrikaans medium. Afrikaans medium institutions — if they claim the right to remain Afrikaans — are quickly branded racist, even though their student body may include all races.

“Education departments are presently exerting great pressure on Afrikaans medium schools to become double or parallel medium schools.  Parallel medium education is an equitable solution provided it can be sustained. Established parallel medium schools, such as Grey College in Bloemfontein, have catered even-handedly for English and Afrikaans speakers for decades. But the situation is different in the parallel medium (and still worse in the double medium) schools that spring up usually at the behest of a department of education.

“Afrikaans schools are converted almost over-night into parallel or dual medium schools without any additional personnel being provided. Depending on the social environment, a parallel medium school becomes reconstituted as a dual medium school on average in five to eight years, and dual medium school becomes an English-only school in two to three years. Some Afrikaans medium schools have become English medium in just three years.

“Though the Constitution recognises mono-lingual schools, officials in the provinces insist that Afrikaans schools become dual or parallel medium; English medium schools are left undisturbed. One must conclude that the tacit aim of the state is English as the sole official language, despite the lip-service paid to multi-lingualism, and the optimistic references to post-apartheid South Africa as a ‘rainbow’ nation.”

They said a recent study has shown that the 1 396 Afrikaans schools in the six provinces in 1993 have dwindled to 844. The fall off in the Free State is from 153 to 97; in the Western Cape from 759 to 564; in Gauteng from 274 to 155; in Mapumalanga from 90 to 3; in the North West from 82 to 13; and in Limpopo Province from 38 to 12.

They said the changes at universities, too, have been severe, as university staffs well know. Ten years ago there were five Afrikaans universities. Today there are none. The government demanded that all universities be open to all, which has meant that all universities have had to become English medium. And no additional funding was forthcoming for the changes. The government policy amounts to a language “tax” imposed on the Afrikaans community for using Afrikaans.

“Only when all schools (and universities) are English will the clamor cease. Academics and educationists are beginning to speak openly of forming pressure groups to save Afrikaans schools, and of using litigation as one of their methods. 59% of Afrikaans parents have said they would support strong action if Afrikaans were no longer a medium of instruction at schools.”
