University taught me to spread my wings

High-profile positions at National Treasury, the World Bank and now also the International Monetary Fund in Washington, mark an illustrious career for UFS Economics alumna, Vuyelwa Vumendlini.

“Go in full force, hands and feet, and accept this opportunity of a lifetime. You won’t regret it.” These words of Dr Minette Smit, her thesis supervisor, proved to be pivotal advice to a young Vuyelwa Vumendlini. At the time, she was doing her BCom Honours in Economics (1996-1999) and was presented with a scholarship opportunity to complete her master’s degree in the USA.

“I was afraid to leave my home and my comfort zone,” she explains. “But looking back, I’m extremely grateful to have taken that step.”

Her studies culminated in an appointment as Senior Adviser to the Executive Director at the World Bank, then Deputy Director-General: International and Regional Economic Policy at the National Treasury, and now as Alternate Executive Director at the International Monetary Fund (IMF) in Washington DC. As an IMF executive board member, Vumendlini represents 23 English-speaking African countries that are members of a constituency. The Executive Board of the IMF has 24 chairs, representing 24 constituencies from its 189 countries’ membership. Among her duties are considering policy issues and surveillance reports, as well as approving and monitoring IMF programmes involving lending and/or technical assistance.

Since this is the second stint in Washington for her and her children, Simphiwe, Enhle, and Anele, settling down was much easier. “Because of the COVID-19 isolation, we were kind of used to being alone at home, so we didn’t find the solitude that bad while we were still making new friends.”

She misses South African food the most – things like biltong and boerewors – and the proximity of favourite restaurants like Ocean Basket and Mugg & Bean. She has fond memories of her study years, working as an assistant in the Department of Economics, hanging out at Mooimeisiesfontein on Saturdays, and building rag floats for Vergeet-My-Nie and Kestell residences. Plans for the future include tackling her PhD in Economics.

Her advice to UFS students: “Be up to date with what is happening around you. Do not be afraid to do things differently. Be agile in your approach to achieving your career aspirations and be ready to take on those opportunities when they present themselves.”

Death may come in adorable little packages

Postdoctoral researcher, Abdon Atangana, of the Institute for Groundwater Studies at the university recently published an article online about the Lassa Haemorrhagic fever in the Natural Computing Applications Forum. In addition to the terminal transmissible sickness recognised as Ebola haemorrhagic fever, there is another strain called Lassa haemorrhagic fever.

The disease is classified under the arenaviridae virus family. The first outbreaks of the disease were observed in Nigeria, Liberia, Sierra Leone, and the Central African Republic. However, it was first described in 1969 in the town of Lassa, in Borno State, Nigeria.

The main host of the Lassa virus is the Natal Mulimammate mouse, an animal indigenous to most of Sub-Saharan Africa. The contamination in humans characteristically takes place through exposure to animal excrement through the respiratory or gastrointestinal tracts.

Mouthfuls of air containing tiny particle of infective material are understood to be the most noteworthy way of exposure. It is also possible to acquire the infection through broken skin or mucous membranes that are directly exposed to the infective material.

“The aim of my research was to propose a novel mathematical equation used to describe the spread of the illness amongst pregnant women in West Africa. To achieve this, I used my newly-proposed derivative with fractional order called beta-derivative. Since none of the commonly used integral transform could be used to derive the solution of the proposed model, I proposed a new integral transform called Atangana-Transform, and used it, together with some iterative technique, to derive the solution of the model.

“My numerical simulations show that the disease is as deadly amongst pregnant women as Ebola,” Abdon said.

Abdon’s research was submitted to one of Springer’s top-tier journals with an impact factor 1.78. The paper was accepted and published February 2015.
