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.

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS
2015-12-07


Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.


Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
