UFS researcher publishes the highest-cited Maths paper in the world in 2017
An article by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies received New Hot Paper status from Clarivate Analytics.
An article on Applied Mathematics, published by Prof Abdon Atangana from the University of the Free State’s Institute for Groundwater Studies in 2017, was recently named New Hot Paper by Clarivate Analytics.

Hot paper status
Essential Science Indicators (ESI) is a unique and comprehensive compilation of science performance statistics and science trends. Data is based on journal article publication counts and citation data from Clarivate Analytics that enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 1 2000+ journals from around the world, this in-depth analytical tool offers data for ranking papers, scientists, institutions, countries, and journals. 

ESI from Clarivate Analytics is updated every two months. The New Hot Papers, which are papers published in the past two years, are in the top one-tenth of one percent (0.1%) for their field and publication period. Prof Atangana’s paper had the highest cite count in the field of Mathematics. 

His article that received the New Hot Paper status is titled: “The new fractional derivative and application to nonlinear Fisher’s reaction-diffusion equation”.

The concept of fractional differential operators with non-singular kernel has captured the minds of several researchers in the past year due to their wider applicability in almost all fields of science, engineering and technology. The new fractional differential operators have opened new windows to model complex real-world problems that could not be modelled using the Newtonian and the well-known Riemann-Liouville fractional differential operators. 

“These operators are the way forward in modelling real-world problems in all disciplines, as they are able to include into mathematical formulation the effect of memory,” Prof Atangana said.

The Atangana-Baleanu fractional derivative
The professor developed a new fractional differential operator, called the Atangana-Baleanu fractional derivative. This derivative is able to describe real-world problems with different scales or problems that change their properties during time and space, for instance, the spread of cancer; the flow of water within heterogeneous aquifers, movement of pollution within fractured aquifers and many others.”

Transformation in higher education discussed at colloquium

The University of the Free State hosted the Higher Education Transformation Colloquium earlier this month on the Bloemfontein Campus.

On Monday 6 May 2013 till Wednesday 8 May 2013 the event brought together a wide range of stakeholders, including some members of university councils; vice-chancellors; academics and researchers; leaders of student formations and presidents of student representative councils; transformation managers; executive directors with responsibility for transformation in various universities, members of the newly established Transformation Oversight Committee and senior representatives from the Department of Higher Education and Training.

The event examined and debated some of the latest research studies and practices on the topic, as well as selected case studies from a number of public universities in South Africa.

Delivering a presentation at the colloquium, Dr Lis Lange, Senior Director of the Directorate for Institutional Research and Academic Planning at the UFS, said transformation in South Africa has been oversimplified and reduced to numbers, and the factors that might accelerate or slow the process have not been taken into account.

Dr Lange was delivering a paper, titled: The knowledge(s) of transformation: an archaeological perspective.

Dr Lange argued that “in the process of translating evolving political arguments into policy making, the intellectual, political and moral elements that shaped the conceptualisation of transformation in the early 1990s in South Africa, were reduced and oversimplified.”

She said crucial aspects of this reduction were the elimination of paradox and contradiction in the concept; the establishment of one accepted register of what transformation was and it is becoming sector-specific or socially blind. This means that the process was narrowed down in the policy texts and in the corresponding implementation strategies to the transformation of higher education, the schools system, the judiciary and the media, without keeping an eye on the structural conditions that can influence it in one way or another.

Dr Lange said the need for accountability further helped with reduction of transformation. “Because government and social institutions are accountable for their promises, transformation had to be measured and demonstrated.”
