Prof Paul Oberholster and Prof Zakkie Pretorius


Two staff members from the University of the Free State (UFS) are nominated for the Science Oscars for their outstanding work and contributions to science over the years. 

Prof Pretorius is nominated in two categories, namely the Special Annual Theme Award: Research and development (R&D) and innovation in Plant Health as well as the Lifetime category.  The Special Annual Theme Awards are made in recognition of the International Year of Plant Health (2020), as declared by the United Nations.

Prof Oberholster is nominated for the NSTF-Water Research Commission Award. This award is for an outstanding contribution to science, engineering, and technology (SET) and innovation in South Africa in terms of sustainable water management, knowledge generation, and solutions over the past five to ten years, and is awarded in recognition of demonstrated leadership and impact.

Science Oscars of South Africa

The NSTF-South32 Awards are referred to as the ‘Science Oscars’ of South Africa and are the largest, most comprehensive, and sought-after national awards of its kind in the country. It was also the first science awards in South Africa.

Prof Oberholster says it is a privilege to be nominated and selected as a finalist in his specific field of interest.
“I always believe the best person will win the award. At this level of competition, it can go both ways. I was nominated by the university for my scientific contribution to water resource management in South Africa over the past 10 years, with special reference to the field of passive wastewater treatment,” says Prof Oberholster.

Although this is the first time that he has been nominated for the NSTF-Water Research Commission Award, Prof Oberholster has previously been nominated in the Innovation category.

Prof Oberholster, whose research focus area is the use of freshwater algae to treat acid mine drainage or domestic wastewater, has previously also won the Excellence Award: CSIR:NRE Outstanding team contribution: Project Leader: Coal tech, WRC and SANBI, Wetland restoration project; and the Excellence Award: CSIR:NRE Innovation: Algae technology for sewage treatment in South African rural areas.

Innovative technology 

This innovative, low-cost green technology assists in the effective and efficient removal of nutrients and bacteria in effluents discharged from wastewater treatment works to improve human health risk, create economic opportunities, and protect downstream ecosystem services. This technology is currently being rolled out to other SADC countries by the African Development Bank. In the case of acid mine drainage treatment, the technology provides a ‘walk-away’ solution for the mining industry. These systems are largely self-sustainable, using no electricity or chemicals, and can be maintained by a semi-skilled workforce.

Prof Pretorius, who has extensive expertise in diseases of field crops – more specifically the rust diseases of small grain cereal crops, has recently been awarded Honorary Membership by the Southern African Plant Breeders’ Association (SAPBA). His colleague, Prof Liezel Herselman, Associate Professor in the Department of Plant Sciences, was presented with a Fellow Award.

• A new, specially arranged virtual Awards Gala Event will be livestreamed on Thursday, 30 July 2020 at 18:45 for 19:00 until 20:30 to honour the finalists and announce the winners.

The state of HIV/AIDS at the UFS
2010-05-11

“The University of the Free State (UFS) remains concerned about the threat of HIV/AIDS and will not become complacent in its efforts to combat HIV/AIDS by preventing new infections”, states Ms Estelle Heideman, Manager of the Kovsies HIV/AIDS Centre at the UFS.

She was responding to the results of a study that was done at Higher Education Institutions (HEIs) in 2008. The survey was initiated by Higher Education AIDS (HEAIDS) to establish the knowledge, attitudes, behaviours and practices (KABP) related to HIV and AIDS and to measure the HIV prevalence levels among staff and students. The primary aim of this research was to develop estimates for the sector.

The study populations consisted of students and employees from 21 HEIs in South Africa where contact teaching occurs. For the purpose of the cross-sectional study an ‘anonymous HIV survey with informed consent’ was used. The study comprised an HIV prevalence study, KABP survey, a qualitative study, and a risk assessment.

Each HEI was stratified by campus and faculty, whereupon clusters of students and staff were randomly selected. Self-administered questionnaires were used to obtain demographic, socio-economic and behavioural data. The HIV status of participants was determined by laboratory testing of dry blood spots obtained by finger pricks. The qualitative study consisted of focus group discussions and key informant interviews at each HEI.

Ethical approval was provided by the UFS Ethics Committee. Participation in all research was voluntary and written informed consent was obtained from all participants. Fieldwork for the study was conducted between September 2008 and February 2009.

A total of 1 004 people participated at the UFS, including the Main and the Qwaqwa campuses, comprising 659 students, 85 academic staff and 256 administration/service staff. The overall response rate was 75,6%.

The main findings of the study were:

HIV prevalence among students was 3,5%, 0% among academics, 1,3% among administrative staff, and 12,4% among service staff. “This might not be a true reflection of the actual prevalence of HIV at the UFS, as the sample was relatively small,” said Heideman. However, she went on to say that if we really want to show our commitment towards fighting this disease at our institution a number of problem areas should be addressed:

  • Around half of all students under the age of 20 have had sex before and this increased to almost three-quarters of students older than 20.

     
  • The majority of staff and a third of students had ever been tested for HIV.

     
  • More than 50% of students drink more than once per week and 44% of students reported being drunk in the past month. Qualitative data suggests that binge drinking over weekends and at campus ‘bashes’ is an area of concern.

Recommendations of the study:

  • Emphasis should be on increased knowledge of sexual risk behaviours, in particular those involving a high turnover of sexual partners and multiple sexual partnerships. Among students, emphasis should further be placed on staying HIV negative throughout university study.

     
  • The distribution of condoms on all campuses should be expanded, systematised and monitored. If resistance is encountered, attempts should be made to engage and educate dissenting institutional members about the importance of condom use in HIV prevention.

     
  • The relationship between alcohol misuse and pregnancy, sexually transmitted infections (STIs), HIV and AIDS needs to be made known, and there should be a drive to curb high levels of student drinking, promote non-alcohol oriented forms of recreation, and improve regulation of alcohol consumption at university-sponsored “bashes”.

     
  • There is need to reach out to students and staff who have undergone HIV testing and who know their HIV status, but do not access or benefit from support services. Because many HIV-positive students and staff are not receiving any kind of support, resources should be directed towards the development of HIV care services, including support groups.

Says Heideman, “If we really want to prove that we are serious about an HIV/AIDS-free campus, these results are a good starting point. It definitely provides us with a strong basis from which to work.” Since the study was done in 2008 the UFS has committed itself to a more comprehensive response to HIV/AIDS. The current proposed ‘HIV/AIDS Institutional response and strategic plan’, builds and expands on work that has been done before, the lessons learned from previous interventions, and a thorough study of good practices at other universities.
