Renata van Reenen
Renata van Reenen has been a South African Sign Language (SASL) champion since primary school, and she is using her postgraduate degree to further SASL in higher education.

Renata van Reenen, a master’s student at the University of the Free State (UFS), recalls how a school talk in 1998 by Deaf activist Johan Gouws instilled in her a kind of ‘duty’ to become a champion for Deaf people. Van Reenen, who in 1987 became the first Deaf child in South Africa to receive a cochlear implant, says it was at this talk that she realised that, as a Deaf person, she has her own language, identity, and culture – and that she is not “a person with a disability”. 

Van Reenen is currently a language facilitator in the UFS Department of South African Sign Language (SASL) and Deaf Studies, and she believes that Deaf students should be empowered to embrace their attributes. Her interests include exploring different sign languages around the world, Deaf issues, and how Deaf children are supported in schools for the Deaf. “One of my hobbies is to put my creative ideas on paper, and I would like to develop and record these stories in SASL so they can be accessible to Deaf schools as resource materials,” she says. “These materials would then also be accessible when teaching the subject South African Sign Language as a Home Language.”

Van Reenen, who worked as an assistant teacher at a school for the Deaf for seven years, is passionate about SASL and the lived experiences of the Deaf. We asked her to share some views on empowering the Deaf and SASL: 

Why is it important to empower Deaf students?

When I was 17, I had no Deaf identity. I did not understand sign language and how it was used – when the Deaf person gave a speech at the school, it changed my life. I realised that I am a Deaf person with my own language, identity, and culture, and that I am not a person with a disability. I strongly believe that Deaf students need to be empowered to fully embrace their identity, language, and culture, and through this expectance show the world who we are. My favourite motto I always share with my Deaf learners is: “Believe in yourself, show them what you can do.” I also encourage them to continuously teach Hearing students the beautiful language, as the famous Deaf quote states: “Sign language is the noblest gift God has given to Deaf people.” George Veditz, the former president of the National Association of the Deaf of the United States, said, “As long as we have Deaf people on Earth, we will have signs.” He protected our language at a time (the early 20th century) when the world strongly believed that Deaf people had to learn through oralism and had to learn spoken language in order to function as a “normal person” alongside hearing people.

As a Deaf person, do you believe the UFS community is doing enough to accommodate you, and how do you feel about being part of the Department of SASL and Deaf Studies? 

When I received a link for a workshop I had to attend, I was so overwhelmed when I saw the interpreter on the video link, and knew that it would be extremely helpful for me during my research. The UFS Centre for Universal Access and Disability Support made sure I have full access to any workshops the university provides. It is amazing that my supervisor can also sign. That made me feel at home, being in a Deaf world without communication barriers. The department is an amazing team that supports and encourages me during my studies.

What will you be doing in honour of Deaf Awareness Month?

The SASL Department and I, along with Deaf Studies, have organised a “Signing Space” event in September to bring Deaf and Hearing students together to socialise with each other. This event will give Hearing students the opportunity to learn about the Deaf world. During this event I will give a small presentation such as “Poetry in SASL” that will show that Deaf people have their own literature, and that it forms part of their language, SASL. We will not only focus on presentations but also on fun activities, such as games that are prominent within the Deaf community. 

Why did you decide to pursue your MA at the UFS? 

During the coronavirus pandemic I applied to the University of Gallaudet in Washington, DC to study for a Master of Education in Sign Language degree. Gallaudet is the world's only university in which all programmes and services are specifically designed to accommodate deaf and hard of hearing students. I was accepted to study further and to ultimately become a teacher or lecturer. My aim was to train Deaf adults to qualify in different areas of SASL, ranging from SASL Linguistics, SASL Pedagogy, SASL Media Production, and so forth. In an ideal world these could be offered as short courses through some tertiary institutions which already offer SASL on undergraduate and postgraduate levels. Unfortunately, I did not have enough support, but I did not let it stop my dream. I decided to change my university of choice and applied at the University of the Free State. I am pursuing my MA degree and continuing my studies as a Deaf person. The University of the Free State is providing and recognising SASL. This is a positive step, as South African Sign Language will soon be the twelfth official language of South Africa.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
