Think three minutes is a long time
One slide and three minutes was all they had to present their research. Winners of the UFS Three-Minute Thesis competition in the Master’s category are from left: Nigel Masalla, Phuthi Samuel Masingi and Vuyisa Sigwela.

It may take three minutes to make noodles, but imagine presenting the 80 000-word research you spent months writing in just three minutes.

For master’s and PhD students participating in the annual institutional Three-Minute Thesis (3MT) competition at the University of the Free State (UFS), three minutes seem to go as fast as three seconds. Each participant is given three minutes to present the essence of their research, explaining the problem, methodology used, as well as the importance of their research using one slide.

A jubilant audience of staff members and students gathered at the Equitas Auditorium on the Bloemfontein Campus for the annual institutional 3MT competition. Interesting research topics across different fields of study, which the participants had spent months and even years researching, were presented in the master’s and PhD categories. After each presentation, a panel of judges and the audience had the chance to ask the participants questions on their research.

The competition is part of the initiative by the UFS Postgraduate School to showcase postgraduate research across disciplines, faculties, and universities. Participation in this competition helps to develop academic, presentation, and research communication skills to ensure that research students can effectively communicate their research in a language that even non-specialists can understand. 

It is the mandate of the school to “create an enabling environment for postgraduate students to excel in their pursuit of their academic quests”, according to Prof Witness Mudzi: Director of the UFS Postgraduate School. 

Winners at the event:

PhDs
• Third prize: Trudie Strauss - Babelish Confusion: Finding Statistical Structure in the Diversity of Languages (R3 000 cash prize)
• People’s choice: Nokuthula Tlalajoe - The transition of undergraduate first-year students into the MBChB programme: Social learning and integration

Master’s
• First prize: Phuthi Samuel Masingi   Physical demands of South African Football (R6 000 cash prize)
• Second prize and people’s choice: Nigel Masalla   “ Stealthing” – lifting the veil on non-consensual condom removal (R4 000 cash prize)
• Third prize: Vuyisa Sigwela - Extraction, characterisation and application of betalains from beetroot, cactus pear and amaranth (R2 000 cash prize)

The UFS will be represented by Trudie Strauss at the national 3MT competition on 26 October 2018. The national competition will take place on the UFS Bloemfontein Campus

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
