Fostering human capabilities in universities may potentially transform education, says Prof Melanie Walker.

Education is at the centre of human life, and has the potential to be a crucial support for democratic life. Prof Melanie Walker’s recent research paper strikes a balance in dealing with people, education and the implications for democracy through the lens of human capabilities theory and practice and her own research.

People and papers

In her capacity as the SARChI Chair in the Higher Education and Human Development Research Programme at the University of the Free State (UFS), Prof Walker recently published a paper titled: Defending the Need for a Foundational Epistemic Capability in Education. It appeared in the special issue of the Journal of Human Development and Capabilities in honour of renowned Nobel Laureate Amartya Sen’s 85th birthday.

Nurturing epistemic justice

Within the context of existing literature such as that of Sen’s concern with the value of education on the one hand, and public reasoning on the other, Prof Walker argues for a foundational epistemic capability to shape the formal education landscape – as well as quality in education – by fostering inclusive public reasoning (including critical thinking) in all students. It would contribute to what Sen calls the ‘protective power of democracy’ and shared democratic rights, which, he argues, are strongly missed when most needed.

“Sen’s approach asks us to build democratic practices in our university and in our society in ways which create capabilities for everyone. If our students learn public reasoning in all sorts of spaces in university, including the pedagogical, they may carry this into and back to society,” she said.

Educating for equality

Empowering society and fighting for justice are some of the crucial contributions made possible through fostering the epistemic capability of all students. “The capability requires that each student is recognised as both a knower and teller, a receiver and a contributor in critical meaning and knowledge, and an epistemic agent in processes of learning and critical thinking,” states Prof Walker.

In a young democracy like South Africa’s, inclusive public reasoning becomes all the more essential in order to achieve equality, uphold rights and sustain democracy as enshrined in the constitution, thereby improving people’s lives.

Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
