Inaugural lecture focuses on understanding society
Dr Kristina Riedel, Head of the UFS Department of Linguistics and Language Practice with Prof Kobus Marais at his inaugural lecture in May.

Understanding what the terms ‘social’ and ‘cultural’ mean and where they come from is important for Prof Kobus Marais. “If one thinks about it carefully, there was a time in the history of the universe and Earth that terms like ‘social’ and ‘cultural’ did not exist. So, if they did not exist from the very beginning, they must have emerged through some process,” he said at his inaugural lecture held earlier this year.

Prof Marais is a senior lecturer in the Department of Linguistics and Language Practice at the University of the Free State (UFS). His interest is in translation studies, but he is conceptualising translation as a technical term that refers to the semiotic process   in other words, the process through which living organisms create meaningful responses to an environment. 

Semiotics entails the study of signs, and it holds that anything in the universe can act as a sign or be interpreted as one. “A tune can be a sign of resistance against political domination, such as Give me hope, Jo’anna, a song by Eddie Grant, and smoke can be a sign of fire, just as the word ‘rose’ could be a sign of a sweet-smelling flower of any colour,” Prof Marais said. 

The universe is perfused by signs, and we are constantly interpreting them, from traffic signs to buildings to agricultural practices to more abstract things like ‘the law’, ‘politics’, ‘economics’ or ‘religion’. All of these things mean something to us and were made as meaningful responses to an environment.

Inaugural lectures vital part of any university
“Inaugural lectures afford professors the opportunity to table a broader research agenda as well as the opportunity to reflect on meta-disciplinary concerns,” Prof Marais said.

He said during the lecture, he had worked out “a theory of translation that explains some aspects of where social/cultural things come from and how they come to be”. An idea that society, and or culture, are a result of translation processes, that is, “processes in which organisms (human beings in this case) respond to an environment in a meaningful way by creating social relationships and cultural phenomena”. 
“Social and cultural phenomena thus all have a meaningful (semiotic) dimension or aspect that I would like to study,” he said.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
