Researching inequalities and higher education
At the International Colloquium on Researching well-being, agency and structural inequalities, were from the left: Prof Melanie Walker, Dr Emily Henderson (Warwick University, UK), and Prof Thierry Luescher (Human Sciences Research Council).

Researchers from the University of the Free State (UFS), University of Minnesota, Lancaster University, University College London, and University of the Western Cape came together at the Bloemfontein Campus for a dynamic and exciting International Colloquium on Researching well-being, agency and structural inequalities: comparative perspectives. 

Prof Melanie Walker’s South African Research Chairs Initiative (SARChI) in Higher Education and Human Development group has invited experienced and early-career scholars to deliberate on matters ranging from marginalisation, decolonisation, inclusion, enhancing capabilities, negative capability, power, and agency in education. Across the papers, education was understood as having the potential to redress inequality, but at the same time it also reproduces such inequalities.
 
Freedoms in higher education

Following the colloquium which took place on 19 September 2018, the SARChI Chair celebrated the launch of Dr Talita Calitz’s book. Dr Calitz is currently a Lecturer in the Department of Education Management and Policy Studies at the University of Pretoria; she completed her doctoral research and a postdoctoral research fellowship under the UFS SARChI Chair. Her book, titled Enhancing the Freedom to Flourish in Higher Education: Participation, equality and capabilities, explores the insight that student narratives can offer to debates about the complex reasons why some students flourish at university while others are socially and academically marginalised.

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.
