Mother tongue pride

A unique public speaking competition hosted in the small town of Philippolis has done wonders to not only build confidence in young mother tongue speakers, but to broaden the cultural perspectives of an entire community.

The Philippolis Public Speaking Competition has been hosted by the Unit for Language Facilitation and Empowerment (ULFE) and the Department of Community Engagement (CE) at the University of the Free State (UFS) since 2013. What started as a small competition for learners in this Southern Free State town, has grown into a much-anticipated annual event, drawing participants from schools in neighbouring towns such as Trompsburg, Bethulie, Jagersfontein, Fauresmith, Gariepdam, and Reddersburg.

Talking about heritage

Every year, learners from Grades 6 to 9 are invited to present a speech on a specific heritage-related topic. Participants are encouraged to speak in their mother tongues – which in this region are mainly Afrikaans, Sesotho, Setswana, and isiXhosa.

Interpreters from the UFS ULFE ensure that the audience can follow each speech. For the past few years, deaf learners from the Bartimea School for the Deaf and Blind in Thaba Nchu and Re Tlameleng School for the Deaf in Kimberley have made welcome appearances, assisted by UFS sign language interpreters.

“This is a wonderful opportunity to teach our young people about acknowledging and respecting different opinions – but also to consider perspectives from differently abled individuals,” enthuses Anita Muller, a teacher from Bergmanshoogte Primary School, who has been involved in the competition from the very beginning.

“Learners in rural areas so often believe they don’t have a voice, and that nobody is interested in their opinions,” she continues.

“This competition does wonderful work in building feelings of self-worth and self-confidence. And it is usually a welcome opportunity for our broader community to get together, learn about one another’s cultures, and change perspectives.” 

Embracing individuality

Jani de Lange, UFS Lecturer in South African Sign Language and Deaf Studies, and one of the coordinators of the project, says she was excited to note that the master of ceremonies of last year’s competition was a former participant in the very first event.

“This project gives me a sense of pride and reminds me why I am part of the UFS. It has been a real eye-opener to see how important it is for those involved,” she says.

“It encourages our young people to embrace their individuality, as we celebrate the cultures and traditions of all those who participate,” says Mabatho Ntsieng from the Engaged Scholarship Office. She says young people often lose sight of where they come from. By giving them opportunities to research topics linked to their heritage and then present their speech in their mother tongue, they can return to their cultural roots.

“It is wonderful to see how proud these participants are and the impact it has on the schools and the community.”

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
