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.

Plant eco-physiologist finds effective solutions for crop optimisation

that the product has been tested
on a crop.

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
