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.

The University of the Free State’s 2015 Winter Graduations, which took place from 1-2 July 2015 on the Bloemfontein Campus offered several highlights. Three global leaders received honorary doctorates. A further 2 000 degrees and diplomas were conferred to graduates in the seven faculties of the university.

For the first time in the history of the UFS, three PhDs in Architecture were awarded simultaneously. Hendrik Auret, Gerhard Bosman, and Madelein Stoffberg’s outstanding achievements are a milestone in the university’s pursuit of academic excellence.

Furthermore, three PhDs were conferred on graduates from the Department of Consumer Science in the Faculty of Natural and Agricultural Sciences. Ismari van der Merwe, Natasha Cronje, and Gloria Seiphetlheng set a precedent when they walked across the Callie Human stage to collect their doctorates at the same graduation ceremony.

This year, the university produced 66 Doctors of Philosophy in various fields of study. Six of these PhDs were awarded in the Department of Physics. Three graduates in the Department of Soil- and Crop- and Climate Sciences received PhDs at the Winter Graduation. They are Tesha Mardamootoo, Elmarie Kotzé, and David Chemei.

Keynote speakers provide enlightenment to graduates

On Wednesday 1 July 2015, Dr John Samuel, SA’s leading education expert, addressed 707 diploma graduates from the Centre for Financial Planning Law and the School of Open Learning. For the graduates’ future reference, Samuel offered invaluable knowledge he had accumulated over the years as Chief Executive of the Nelson Mandela Foundation. “One of the lessons I have learnt was not only the importance of time, but it was in fact what being on time demonstrated,” he said. “Being on time was demonstrating respect, respect for the people you are meeting, and for the occasion.”

On the second day of graduation, Nataniël, South African singer, songwriter, and entertainer spoke to Master’s and doctoral graduates in the Faculties of Economic and Management Sciences, Humanities, Education, Health Sciences, Law, Theology, and Natural and Agricultural Sciences. His keynote spoke to the graduates’ sense of resolve in saying, “nothing is ever accidental. It is always with a purpose, it is your turn to make the world a better place.” He added that “it is important to strive for excellence and to be proud of what you are doing.”

Honorary doctorate recipients in a nutshell

Dr Samuel is one of the three exceptional global leaders to receive honorary doctorates from the university on 1 July 2015. His accolade was presented by the Faculty of Education. He has contributed to the Public Participation Education Network (PPEN) campaign as a founding member. He established the Centre for Education Policy Development, the Joint Working Group (for The National Party Government and the ANC), the National Education Conference, and the National Education and Training Forum. In addition, he made leadership contributions to the First Education and Training White Paper, the first Green Paper on Higher Education, and is the CEO of the Oprah Winfrey Leadership Academy for Girls. The WK Kellogg Foundation in the USA operates under his directorship.

Dr Lakhdar Brahimi received an honorary doctorate from the Centre for Africa Studies. Algerian-born Brahimi was first involved with the United Nations (UN) in 1992, and has since been deployed all over the world on peacekeeping missions. Amongst many other countries, he has worked as a mediator for South Africa, Haiti, Afghanistan, Iraq, Syria, Democratic Republic of Congo, Cameroon, Burundi, Angola, Liberia, Nigeria, Sudan, and Côte d’Ivoire on behalf of the UN. He also played a direct role in South Africa’s democratic transition as a special representative in 1993/4.

Dr Mercy Amba Oduyoye received an honorary doctorate from the Faculty of Theology. Dr Oduyoye is widely regarded as one of the most influential women theologians in Africa. She was the first black woman to receive a degree in Theology in 1965 from Cambridge University in the United Kingdom. She continues to shift the paradigm of gender in theology internationally as the director of the Institute of African Women in Religion and Culture at the Trinity Theology Seminary in Ghana.

In closing the academic celebrations

Vice Rector: Academic, Dr Lis Lange, commended the class of 2014 for making their contribution to the educational system. Prof Jonathan Jansen, Vice Chancellor and Rector, also congratulated the graduates in closing.

“This is a day many have worked very hard towards, it is an enormous achievement as well as a development in the quality of research, and the courage to research,” he said in a vote of confidence.

Dr Khotso Mokhele, Chancellor of the UFS, applauded the university in light of the increased number of female graduates who completed their degrees with distinctions. The transcendence of demographics, both in terms of gender and race, on a postgraduate level, increases the hope of achieving gender equality in both the academic arena and South Africa.
