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.”

A real indaba it was
2010-09-07

Pictured from the left, are: Prof. Dennis Francis (Dean), Prof. Rita Niemann (Director: Postgraduate Studies and Research) and Prof. Rob Pattman (Keynote speaker: UKZN).

No expert panels! No rubrics! Only a fair measure of healthy anxiety that goes with public speaking!

These features describe the meeting that staff members from the Faculty of Education recently had at Indaba Lodge on the banks of the Modder River. The purpose of this get-together was to create a time and space where staff members could not only celebrate their own research efforts, but also acknowledge, support and validate one another’s work.

The day kicked off with the dean’s research vision for the faculty. Thereafter seven staff members doing their Ph.D.s were introduced. Their presentations were followed by inputs from the guest speaker, Prof. Rob Pattman from the University of KwaZulu-Natal (UKZN). He congratulated the presenters on their cutting-edge research, their eloquence and the manner in which they managed to communicate complex matters in simple ways. Ideas he shared from his own research on social identities and critical agency (with a focus on gender and race) served to affirm the relevance of the topics presented by the Ph.D. candidates in transforming the education system as well as the South African society as a whole.

A festive lunch, in honour of retiring Prof. Johan van Staden, brought an affective dimension to the Indaba in the form of heart-felt goodbye messages from colleagues who had shared his academic life for more than 20 years.

After lunch five master’s students had the opportunity to share their research in the form of poster presentations. A lively interest among participants and critical, but constructive questions characterised this session. A potpourri session followed, comprising work in progress, completed surveys, research awards and innovative research methods.

The wrap-up by Prof. Dennis in no uncertain terms affirmed that researchers in the Faculty of Education not only crossed the Modder River, but also the proverbial Rubicon on 21 August. It was envisaged that henceforth:
- Supervision will take on a collaborative character.
- Soon a research forum for Ph.D. students and their supervisors will be established where these students and supervisors can start practising their agency.
- Instead of relying on outside experts who come and “tell” faculty staff members what to do, insiders should start building their own vibrant research-based practices by forming reading groups to discuss seminal works (e.g. Foucault and Freire) and research methodologies (e.g. Burke’s Pentad).

The Indaba was aptly concluded by one of the participants who, on behalf of all attendees, thanked and congratulated the dean on the initiative to give impetus to research. Analogous to the 2010 slogan, Feel it, it is here!, he said: “I feel so inspired and empowered, I can almost taste it!”
