A data scientist and research coordinator at the University of the Free State (UFS), in collaboration with his supervisor at the University of Pretoria (UP), is at the forefront of the fight against the Covid-19 virus with accurate data and analysis.
Herkulaas Combrink of the Centre for Teaching and Learning at the UFS and PhD candidate in Computer Science at the UP, said accurate data is important to prevent widespread panic and sensationalism during a global disaster such as the current pandemic. This information helps people to make informed decisions and to reduce their exposure to the threat of the virus.

Assisting decision-makers

“I, along with colleagues from the World Health Organization, the Centers for Disease Control and Prevention in the USA, the provincial office of the Centers for Disease Control and Prevention, provincial clinicians, and the Free State Department of Health led by Dr David Motau, have been able to progress significantly in terms of evidence-based tools to assist provincial and national decision-makers during these turbulent times.”
“It does come at a cost, though, in that we have worked continuously since the lockdown, dedicating all our time and efforts to the department from all over to ensure that we are not part of some of the global statistics we have seen,” said Combrink. 

A paper written together with his supervisor, Dr Vukosi Marivate, has also been accepted by the Department of Higher Education and Training (DHET)-accredited Data Science Journal.  This paper is related to a framework for sharing public data to the public in a way that is useful, usable, and understandable. 

Ongoing projects

Combrink said it is hard to name all those who are/were involved in the great work done by the Free State Department of Health, but some of them include Dr Elizabeth Reji (Head of Department, Family Medicine), Dr Collin Noel (surgeon, senior lecturer at the UFS), Dr Sammy Mokoena (community health registrar, UFS), Dr Ming-Han Motloung (public health medicine specialist, senior lecturer, UFS), Dr Perpetual Chikobvu (Director: Information Management at the Department of Health, affiliated lecturer at the UFS), as well as Alfred Deacon (lecturer at the UFS), who have worked at some point during this short space of time on one of the many projects. 

Some of the projects include the following:

• A provincial database for screening and monitoring.
• A data pipeline and assembly of hospital information flow, liaised with the NICD, Vodacom, and the different district managers to ensure that the pipeline occurs in a timely manner.
• Digitised paper-based capturing tools for rapid data capturing and processing.
• Incorporated state-of-the-art visualisation tools to action data into useful information for decision-makers in certain areas.
• Provided both provincial and national projections, stress testing different scenarios using a variety of statistical, computational, and/or machine-learning approaches to add to the already existing projections of the Council for Scientific and Industrial Research (CSIR).
• Training healthcare professionals in the field to apply these tools within their own districts.
No easy task

“These aforementioned feats were by no means easy and are not completed yet, but we are getting there. In the foreseeable future, I will be working closely with national and international researchers to deploy a tool for hospital managers in the Free State that will assist them when we move from level 5 to any level below.”

“In addition to this, I am constantly providing support to the Free State Department of Health regarding any analysis required for decision-making purposes. The teams we work in comprise highly competent individuals with a passion for solving problems from multidisciplinary perspectives,” according to Combrink.

Academic delivers inaugural lecture on South African foreign policy
2007-08-06

 

In her inaugural lecture Prof. Heidi Hudson from the Department of Political Sciences, focused on the impact that Pan-Africanist sentiments have had on South Africa’s foreign policy. She also put the resulting contradictions and ambiguities into context. At her inaugural lecture were, from the left: Proff.

Academic delivers inaugural lecture on South African foreign policy

“We are committed to full participation as an equal partner … opposed to any efforts which might seek to project South Africa as some kind of superpower on our continent. … the people of Africa share a common destiny and must therefore … address their challenges … as a united force...” (Mbeki 1998:198-199).

Prof. Heidi Hudson from the Department of Political Science referred to this statement made by president Mbeki (made at the opening of the OAU Conference of Ministers of Information in 1995) when she delivered her inaugural lecture on the topic: South African foreign policy: The politics of Pan-Africanism and pragmatism.

One of the questions she asked is: “Can the South African state deliver democracy and welfare at home while simultaneously creating a stable, rules-based African community?”

She answers: “South Africa needs to reflect more critically and honestly on the dualism inherent in its ideological assumptions regarding relations with Africa. South Africa will always be expected by some to play a leadership role in Africa. At the moment, South Africa’s desire to be liked is hampering its role as leader of the continent.”

In her lecture she highlighted the ideological underpinnings and manifestations of South Africa’s foreign policy. Throughout she alluded to the risks associated with single-mindedly following an ideologically driven foreign policy. She emphasised that domestic or national interests are the victims in this process.

Prof. Hudson offers three broad options for South Africa to consider:

  • The Predator – the selfish bully promoting South African economic interest.
  • Mr Nice Guy – the non-hegemonic partner of the African boys club, multilaterally pursuing a pivotal but not dominant role.
  • The Hegemon - South Africa driving regional integration according to its values and favouring some African countries over others, and with checks and balances by civil society.

She chooses option three of hegemony. “Politically correct research views hegemony as bad and partnership as good. This is a romanticised notion – the two are not mutually exclusive,” she said.

However, she states that there have to be prerequisites to control the exercise of power. “The promotion of a counter-hegemon, such as Nigeria, is necessary. Nigeria has been more effective in some respects than South Africa in establishing its leadership, particularly in West Africa. Also needed is that government should be checked by civil society to avoid it sinking into authoritarianism. The case of business and labour coming to an agreement over the HIV/Aids issue is a positive example which illustrates that government cannot ignore civil society. But much more needs to be done in this regard. South Africa must also be very careful in how it uses its aid and should focus potential aid and development projects more explicitly in terms of promoting political stability,” she said.

Prof. Hudson said: “It is also questionable whether Mbeki’s Afro-centrism has in fact promoted the interests of ordinary citizens across Africa. Instead, elite interests in some countries have benefited. But ultimately, the single most important cost is the damage done to the moral code and ethical principles on which the South African Constitution and democracy is founded.

“In the end we all lose out. More pragmatism and less ideology in our relations within Africa may just be what are needed,” she said.
