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.”

First UFS/AS Young African Scholar Award winner announced

Scholarship in African Studies still faces the challenge of capacity-building to increase ownership by authors and institutions from and on the African continent. It also requires more coordinated efforts to provide the space deserved by African authors in the international domain. In 2015, the University of the Free State (UFS) Centre for Africa Studies joined forces with Africa Spectrum (AS) in a bid to address this issue by establishing the UFS/AS Young African Scholar Award.

This award seeks to strengthen efforts to promote internationally recognised African scholarship in African Studies. One way to achieve this objective is through publishing articles by researchers based in Africa and in the diaspora in Africa Spectrum, an accredited journal compiled by the German Institute of Global and Area Studies in Hamburg.

The inaugural award winner
Fana Gebresenbet Erda, a PhD candidate in a Global and European Studies programme jointly offered by the University of Leipzig (Germany) and Addis Ababa University, wrote the winning article for 2015. He will receive a three-year affiliation to the UFS Centre for Africa Studies as a Research Fellow, along with prize money of R5 000, sponsored by the UFS.

His article, The Ethiopian Developmental State in Its Peripheral Lowlands: Large-Scale Land Acquisitions, the Politics of Dispossession and State Remaking in Gambella, Western Ethiopia, argues that development through large-scale land acquisitions in Gambella, Western Ethiopia, belies a state-remaking project under a dispossessive political economy.

Submission now open
Africa Spectrum invites scholars to submit research articles in the context of the award. In October of each year a review committee selects submissions for review. Those eligible to submit are postgraduate students nearing completion of their PhD theses and postdoctoral scholars who were awarded their PhDs no more than five years earlier at the time of the submission deadline. Those submitting should be from Africa or should be affiliated to African institutions.
