Delegates at the workshop were provided opportunities that many larger conferences do not offer.

The growing body of work examining microvariation in African languages prompted Dr Kristina Riedel and Dr Hannah Gibson, from the University of Essex and research fellow, to work on a research project, “Variation in Sesotho and Setswana as spoken in the Free State”, to document the dialectal variation in the languages as it is spoken in the province. 

“Dr Gibson and I have a joint research project which is funded by a Newton British Academy mobility grant,” says Dr Riedel, Head of the Department of Linguistic and Language Practice at the University of the Free State (UFS).

The duo hosted a workshop on morphosyntactic microvariation (small structural differences that can be observed between closely related languages or dialects) on the UFS Bloemfontein Campus, as part of the Newton Fund research project.  

Research focus on dialectal variation 

Dr Riedel says there has been some linguistic work on both of these languages. “But for Sesotho, linguists have noted that there is no dialectal variation. This seems hard to believe given the size of the population who speak the language,” she says. 

They are looking at speakers in the Free State province for differences in both languages. Speakers themselves also report awareness of dialectal differences and variation between different regions. “We’re also interested in whether they have influenced each other – particularly in places where people speak both of these languages on a day-to-day basis, such as Thaba ’Nchu and Bloemfontein,” Dr Riedel says.

Dr Riedel believes that in the context of an African university it is important to contribute to the development, teaching and support of African languages. “Research on African languages can play an important part of this picture. Furthering our knowledge and understanding of African languages from a linguistic perspective also contributes to our understanding of the world’s languages and linguistic diversity.” 

Workshop creates space for training and skill sharing

The aim of the workshop was to bring together researchers, students and language practitioners to “provide them with some of the insights and training that is helpful when looking at morphosyntactic microvariation”, Dr Riedel says.

The workshop was conducted in two sets. At the first workshop the emphasis was on training and sharing of skills and the second part focused on more research-related presentations. 

The workshop, which took place on 19 July 2019, was attended by delegates from numerous local institutions (Rhodes University, University of the Western Cape and Stellenbosch University) as well as universities in the rest of Africa including the University of Malawi, Dar es Salaam University College of Education and Makerere University in Uganda.

Dr Abdon Atangana cements his research globally by solving fractional calculus problem
2014-12-03

 

Dr Abdon Atangana

To publish 29 papers in respected international journals – and all of that in one year – is no mean feat. Postdoctoral researcher Abdon Atangana at the Institute for Groundwater Studies at the University of the Free State (UFS) reached this mark by October 2014, shortly before his 29th birthday.

His latest paper, ‘Modelling the Advancement of the Impurities and the Melted Oxygen concentration within the Scope of Fractional Calculus’, has been accepted for publication by the International Journal of Non-Linear Mechanics.

In previously-published research he solved a problem in the field of fractional calculus by introducing a fractional derivative called ‘Beta-derivative’ and its anti-derivative called ‘Atangana-Beta integral’, thereby cementing his research in this field.

Dr Atangana, originally from Cameroon, received his PhD in Geohydrology at the UFS in 2013. His research interests include:
• the theory of fractional calculus;
• modelling real world problems with fractional order derivatives;
• applications of fractional calculus;
• analytical methods for partial differential equations;
• analytical methods for ordinary differential equations;
• numerical methods for partial and ordinary differential equations; and
• iterative methods and uncertainties modelling.

Dr Atangana says that, “Applied mathematics can be regarded as the bridge between theory and practice. The use of mathematical tools for solving real world problems is as old as creation itself. As written in the book Genesis ‘And God saw the light, that it was good; and divided the light from the darkness’, the word division appears here as the well-known method of separation of variables, this method is usually employed to solve a class of linear partial differential equations”.

“A mathematical model is a depiction of a system using mathematical concepts and language. The procedure of developing a mathematical model is termed mathematical modelling. Mathematical models are used not only in natural sciences, but also in social sciences such as economics, psychology, sociology and political sciences. These models help to explain systems and to study the effects of different components, and to make predictions about behaviours.”
