Mineral named after UFS professor
Tredouxite (white) intergrown with bottinoite (light grey), a complex hydrous alteration product. The large host minerals are nickel-rich silicate (grey), maybe willemseite, and the spinel trevorite (dark grey).

More than five thousand minerals have been certified by the International Mineralogical Association(IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classificationwebsite, the Mineralogical Magazine and the European Journal of Mineralogy.

Alcinda Honwana: Youth Protests Main Mechanism against Regime
2015-05-25

Prof Alcinda Honwana

"Enough is Enough!": Youth Protests and Political Change in Africa (speech) 

The Centre for Africa Studies at the UFS hosted an interdisciplinary project on the Bloemfontein Campus from 20-22 May 2015.

The project, entitled Contemporary Modes of Othering: Its Perpetuation and Resistance, looked at different perspectives, representations, and art forms of otherness, how it is perceived, and how it is resisted.

The annual Africa Day Memorial Lecture was held on Thursday evening 21 May 2015 at the CR Swart Auditorium. Guest speaker Prof Alcinda Honwana addressed the subject of ‘Youth Protests and Political Change in Africa’.

“Youth now seem able to display what they don’t want, rather than what they do want,” Honwana said in her opening remarks. “Thus, we see the young driven to the streets to protest against regimes.”
 
Honwana shed some light on recent examples of youth protests in Africa that have enjoyed global attention. Looking at the protests in Tunisia (2010), Egypt (2011), Senegal (2012), and Burkina Faso (2014), it is clear that these events in northern and western Africa have inspired others globally. Yet, Honwana stated that, despite these protests, no social economic change has been seen, and has left dissatisfaction with new governments as well.

“Once regimes fall… young activists find themselves more divided, it seems…

“Which leaves the question: Will street protests remain young people’s main mechanism to avert those in power?”

Background on Prof Alcinda Honwana:

Alcinda Honwana is currently Visiting Professor of Anthropology and International Development at the Open University (UK). She was chair in International Development at the Open University, and taught Anthropology at the University Eduardo Mondlane in Maputo, the University of Cape Town in South Africa, and the New School for Social Research in New York. She was programme director at the Social Science Research Council in New York, and worked for the United Nations Office for Children and Armed Conflict. Honwana has written extensively on the links between political conflict and culture, and on the impact of violent conflict on children and youth, conducting research in Mozambique, the Democratic Republic of the Congo, Angola, Colombia, and Sri Lanka. Her latest work has been on youth and social change in Africa, focusing on Mozambique, Senegal, South Africa, and Tunisia.

Honwana’s latest books include:

• Youth and Revolution in Tunisia (2013); 
• Time of Youth: Work, Social Change, and Politics in Africa (2012);
• Child Soldiers in Africa (2006);
• Makers and Breakers: Children and Youth in Postcolonial Africa (2005, co-edited).

Honwana was awarded the prestigious Prince Claus Chair for Development and Equity in the Netherlands in 2007.
