Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health being presented to the acting Chancellor by his supervisor Prof Stephen Brown.

A lecturer from the University of the Free State (UFS) says the need to improve the care of seriously ill children is a vital part of reducing preventable deaths and diseases, and this led him to investigate the use of artificial neural networks to develop models for the prediction of patient outcomes in children with severe illness. The study was done for his PhD thesis. 

This forms the basis for the PhD thesis of Dr Michael Pienaar, Senior Lecturer and specialist in the UFS Department of Paediatrics and Child Health, called, The Development and Validation of Predictive Models for Paediatric Critical Illness in Children in Central South Africa using Artificial Neural Networks. His thesis reports the development and testing of several machine learning models designed to help healthcare workers identify seriously ill children early in a range of resource-limited settings. Combining a systematic literature search and Delphi technique with clinical data from 1 032 participants, this research led to significant progress towards implementable models for community health workers in clinical practice.

Care for critically ill children is a mission and calling 

Dr Pienaar graduated with a PhD specialising in Paediatrics on Monday (12 December) during the Faculty of Health Sciences’ December graduation ceremony. It took him three years to complete this degree. His supervisor was Prof Stephen Brown, Principal Specialist and Head of the Division of Paediatric Cardiology in the Department of Paediatrics and Child Health in the Faculty of Health Sciences at the UFS. Prof Nicolaas Luwes and Dr EC George were his co-supervisors. 

“I have been working in paediatric critical care since 2019 and see the care of critically ill children as my mission and calling in life. At the outset of the project, I was interested in approaches to complex phenomena and wanted to investigate new methods for tackling these in healthcare. 

“I have been interested in technology since childhood and in collaborating with other disciplines since I joined the university in 2019. Machine learning seemed like a great fit that could incorporate these interests and yield meaningful clinical results,” explains Dr Pienaar the reason why he chose this topic for his thesis.

He hopes that, in time, this work will lead to the implementation of integrated machine learning models to improve care and clinical outcomes for children in South Africa. From a scholarship perspective, he continues, his hope is that this work draws interest to this field in clinical research and encourages a move towards incorporating these new methods, as well as skills in areas such as coding and design in the armamentarium of a new generation of clinicians.

Medicine chooses you

According to Dr Pienaar, he always had broad interests, of which medicine is one. “I am very grateful to have found my way in medicine and am humbled and privileged to be allowed to walk with children and their families on a difficult and important journey. I believe this profession will choose you and put you where you are needed if you give it time and are prepared to listen.”

He describes graduating as a complicated ending to this period of his life and the beginning of a next chapter. He was humbled by the graduation ceremony. 

“It was wonderful to graduate with undergraduates and postgraduates in my profession – I felt great pride and solidarity joining these new colleagues and specialists in taking the oath. I am certainly relieved, proud, excited, and happy. I am also very grateful to the university, my promotors, colleagues, friends, and family for supporting me through this process. I must confess, it is also slightly bittersweet, I loved working on this and do miss it, but look forward to the next exciting project. 

“I would like to thank my Head of Department, Dr (Nomakhuwa) Tabane, my supervisors, my family and friends once again. I would also like to acknowledge and thank the National Research Foundation (NRF) as well as the University of the Free State for their assistance with funding this research.”

Professor launches his book, opposition parties attend

“We are good in opposing people, but we’re less good in opposing ideas.” This was how Prof. Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS) introduced the book launch of Against all Odds: Opposition Politics in Southern Africa.

The event was hosted in collaboration with the publisher under the title: Are opposition parties in South Africa in a crisis? This formed part of a series of dialogue sessions, organised by the Centre for Africa Studies, in the run up to the local elections.
 
Amongst those interested who attended the evening in the Senate Hall of the CR Swart Building on the Main Campus were various politicians, students, staff en a panel consisting of academics and the respective provincial representatives of the ANC and DA.
 
Dr Mcebisi Ndletyana from the Human Sciences Research Council (HSRC), acted as arbiter.
 
Proff. Hussein Solomon, author of Against all Odds: Opposition Politics in Southern Africa, also lecturer at the UFS, as well as Dirk Kotzé, Head of the Department of Political Science at Unisa, delivered enriching lectures on the stance and positioning of opposition parties.
 
Prof. Hussein, who spoke first, circumscribed the context of the political climate in the country, based on his book. “The problem that political science encounters is that everybody becomes experts on the internet, while they have no experience of what is happening in South Africa.” He said that when political parties in the country are under discussion, voters often allow myths and/or stereotyping to influence their concept of it. ‘’If there are no opposition parties, there is no democracy and people are deprived of their vote.”
 
Prof. Kotzé stated in his speech that it was not only opposition parties who had to make the government watch its step, but also the status that the country acquired, amongst others, from its connections, i.e. collaborative agreements such as BRICSA and the country’s inclusion in the G20. He left the audience with a question about how they were going to become involved in politics, and with his rhetoric question referred to options like social networks and movements.
 
Mr Sibongile Besani, the ANC'S secretary in the Free State, said the DA grew due to it’s swallowing of other parties; something he claims is taking the country backwards. He also described the use of personalities by opposition parties as means of association a weakness. He added that voters will continue voting for the ANC because they can associate themselves with the party’s vision.
 
In contrast, Mr Roy Jankielsohn, provincial leader of the DA, said voters and parties unite under their core vision for the country as like in the case of the ANC during the liberation struggles.
 
During the question-and-answer session, which followed after Mr Jankielson’s speech, Prof. Kwandiwe Kondlo, upon completion and summary of the discussions, stated firmly that the opposition parties are in a crisis. “The start of the solution is to recognise the problem. That is why our democracy finds itself in the state in which it is; because the opposition does not fulfil the role that they are supposed to fulfil.“ Prof. Kondlo is the head of the Centre of Africa Studies at the UFS.
 
He concluded by stating that the economic basis in the country was not transformed. “We cannot say that people determine their futures if they posses nothing. Opposition parties must start to communicate at this level in order to table something new. Our democracy must become more inclusive at political and material level.”
