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.”

Food insecurity at university campuses under the spotlight
2015-08-20

 

"Food insecurity is   becoming an increasing problem at South African universities, much to the surprise of university managers." - Dr Louise van den Bergh, senior lecturer and researcher at our department of Nutrition and Dietetics

More than 70% of early university dropouts in the country were forced to abandon their tertiary studies because of food insecurity and financial need.

This was one of the conclusions drawn during the first higher education colloquium on food insecurity. The colloquium was hosted on by the University of the Free State (UFS) on the Bloemfontein Campus on 14 August 2015, where researchers from universities across the country shared their research about food insecurity on university campuses.

In South Africa, university campuses are not usually associated with food insecurity but, over the last few years, tertiary education has become more accessible to an increasing number of first-generation students and students from low-income households.

Some of the research indicated that students from lower-income households are often lacking financially, even with bursaries. The research has also shown that students frequently have to use part of their bursary money to support their families. This results in students not having enough money to buy food, which means they will do almost anything to get food.

A study by the UFS Department of Nutrition and Dietetics found that as many as 60% of our students are food insecure, and experience hunger frequently. This study was the first of its kind in South Africa. In 2011, the UFS launched the No Student Hungry Bursary Programme to provide food bursaries to food-insecure students.

At the opening of the colloquium, Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said by helping students with a basic commodity like food, you give them much more than food; you give them humanity and dignity.

Dr Louise van den Bergh, senior lecturer and researcher in the UFS Department of Nutrition and Dietetics, explains that the problem is considerably more complex than just providing for students financially.

Dr Van den Bergh says that funders need to reassess bursaries, keeping issues such as food insecurity in mind, and not focusing just on tuition.
