Social work

South Africa celebrated Human Rights Day and World Social Work Day on 21 March 2023. Social work is a profession that advocates for the human rights of people as well as focuses on the responsibility that comes with these rights. Just as the Bill of Rights is the cornerstone of democracy and protects our rights, the social work code of ethics is the cornerstone that ensures quality social work services. 

The University of the Free State (UFS) second-year social work students took an oath on 22 March which binds them to the social work code of ethics. Social workers have the Global Agenda for Social Work and Social Development which consists of four pillars. Focus is drawn to the last pillar, Strengthening Recognition of the Importance of Human Relationships. Human relationships are the core of social work and social development. These relationships take various forms, including social, personal, interpersonal, and therapeutic relationships, among various people and in various settings. In relationships where people flourish, trust is crucial. In contrast, mistrust skews relationships in a negative way. 

Respecting diversity through joint social action

The Ubuntu pan-African philosophical framework is the greatest place to understand the significance of human relationships. To promote and strive for the strengthening of relationships, this year’s theme for Social Work Day is “Respecting Diversity Through Joint Social Action”. If we can stop criticising people that do not live, believe, or think according to our constructed standards of being, we will be able to do so much more as humanity. If we start embracing peoples’ diversities and take time to start building relationships with various people and bridge any existing gaps, we will realise that diversity is an integral aspect of changing the world in a positive manner. Corresponding to human rights and the theme of World Social Work Day, is the theme “Destigmatising intellectual disability through shifting attitudes” for Intellectual Disability Awareness Month [IDAM] which also takes place later in March. Another way through which we can start building relationships and embrace diversity is by participating in this year’s South African Federation for Mental Health challenge where CEOs of different institutions are challenged to spend one day in a wheelchair as part of an awareness-raising campaign to destigmatise intellectual disabilities.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

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.
