Dr Tafadzwa Maramura participated in a study on couplepreneurs and ways in which they influence their children to become better entrepreneurs.

After years of hard work, the lonely entrepreneur rode off into the sunset. No family. No one to share the lived experience with. The entrepreneurial journey can be a recipe for loneliness. However, it does not have to be, you can enjoy an entrepreneurial family that leaves a legacy.

Dr Tafadzwa C Maramura, Senior Lecturer in the Department of Public Administration and Management at the UFS participated in a study with Drs Eugine Maziriri (University of Johannesburg), Miston Mapuranga (University of Pretoria), Brighton Nyagadza (Marondera University of Agricultural Sciences) on couplepreneurs and ways in which they influence their children to become better entrepreneurs. The interinstitutional study drew on several fields of expertise and was a fresh addition to the research on access to water that Dr Maramura is doing.

Couplepreneurship is a concept that explains businesses owned and operated by married and/or cohabiting couples. According to Dr Maramura: “The development of couplepreneurship in South Africa as an emerging economy has led to increasing interest in the study of how kids are inspired and/or influenced by their parents towards starting their own and to participate in the already existing family enterprises.”

Nurturing entrepreneurial potential

Couplepreneurs are in a great position to raise kidpreneurs. Who better to listen to the heroic stories of how mom and dad started off with a big dream, growth mindsets, and steadfast commitment to building their business than their offspring? Like teaching a person how to fish rather than giving them fish, couplepreneurs do not hand their kids a business, they teach them how to run and grow a business.

Dr Maramura believes that nurturing an entrepreneurial potential is the result of “encouraging resilience, adaptability, and a willingness to embrace failure, even as a learning opportunity”. Combine this with an environment that promotes creativity, critical thinking, and problem-solving skills, and you have the recipe for a kidpreneur to become an entrepreneur. Now add more ingredients: parents who offer support, mentorship, and exposure to diverse experiences. Put it in the heated oven called business – and you have created the meal all entrepreneurs crave: Legacy.

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.
