The meaning of race, culture and sexism in Africa takes a different tone than it does in the West. The West has always tried to create an identity for Africa, but the real question remains: “What does it mean to be an African?’ 

“My aim with this book was to see how discourse is formed and what it means when you say the word ‘African’, which is meaningless. You have to look back to understand how that was created,” said Prof Charles Ngwena.

Prof Ngwena’s new book, asks the critical question,‘What is Africanness?’ Fully titled, What is Africanness? Contesting nativism in race, culture and sexualities is a timely contribution to contemporary South African debates on issues of decolonisation, race, ethnicity, nation building and belonging.

Identity formation a crucial element

“The book speaks directly to African cultural heritage and deconstructs a Western-imposed and homogenising framework for understanding Africanness,” said Dr Nadine Lake from the Centre for Gender and Africa Studies (CGAS) at the University of the Free State (UFS).

Prof Ngwena foregrounds the importance of intersectionality when approaching issues of race, culture and sexuality and writes: “Genericness is ineluctably homogenising. It can serve to obscure heterogeneities among women, pre-empting the need to explore the implications of differences among women in feminist theory and praxis.

“Identity is being and becoming. It is always changing. What young people think of identity is not the same way their grandparents thought about it,” said Prof Ngwena. He added that his contribution through this book was to underlay identity formation.

The book, published by Pretoria University Law Press (PULP), was launched in a joint venture by CGAS, the Centre for Human Rights at the University of Pretoria on Tuesday 11 September 2018 at the UFS.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
