Dr Michael Pienaar is a lecturer in the University of the Free State’s (UFS) department of Paediatrics and Child Health.

A lecturer from the University of the Free State’s (UFS) department of Paediatrics and Child Health is investigating the use of artificial neural networks to develop models for the prediction of patient outcomes in children with severe illness.

Dr Michael Pienaar, senior lecturer and specialist, is conducting this research as part of his doctoral research and the study deals primarily with the development of models that are designed and calibrated for use in South Africa. These artificial neural networks are computer programs designed to mimic some of the learning characteristics of biological neurons.

The potential applications of models

According to Dr Pienaar these models have traditionally been developed in high-income nations using conventional statistical methods.

“The potential applications of such models in the clinical setting include triage, medical research, guidance of resource allocation and quality control. Having initially begun this research investigating the prediction of mortality outcomes in the paediatric intensive care unit (PICU) I have broadened my scope to patients outside of PICU, seeking to identify children early during their illnesses who are at risk of serious illness requiring PICU,” says Dr Pienaar.

The research up until now has been directed towards the identification of characteristics that are both unique to children with serious illness in South Africa, but also accessible to clinicians in settings where expertise and technical resources are limited.

Research still in the early changes

The research is still in its early stages but next year a series of expert review panels will be held to investigate the selection of variables for the model, after which the collection of clinical data will begin. Once the data has been collected and prepared, a number of candidate models will be developed and evaluated. This should be concluded by the end of 2022.

Says Dr Pienaar: “The need to engage with the rapid proliferation of technology, particularly in the realms of machine learning, mobile technology, automation and the Internet of Things is as great in medical research now as it is in any academic discipline.

“It is critical that research, particularly in South Africa, engage with this in order to take advantage of the opportunities offered and avoid the dangers that go paired with them. Together with the technology as such, it has been essential to pursue this project as an interdisciplinary undertaking involving clinicians, biostatisticians and computer engineers.”

Hope for the research  

Dr Pienaar says he was very fortunate and grateful to be the recipient of a generous interdisciplinary grant from the UFS which has allowed him to procure software and equipment that is critical to this project.

“The hope for this research is that the best performing of these models can be integrated with a mobile application that assists practitioners in a wide range of settings in the identification, treatment and early referral of children at high risk of severe illness. I would like to expand this research project to include other countries in Africa and South America and to use it as a bridge to collaboration with other clinical researchers in the Global South,” says Dr Pienaar.

As an early career researcher, Dr Pienaar hopes that this research can serve as a platform to build a body of research that uses the rapid technological advances of these times together with a wide range of collaborations with other disciplines in the pursuit of better child health.

He concludes by saying that he has had excellent support thus far from his supervisors, Prof Stephen Brown (Faculty of Health Sciences, UFS), Dr Nicolaas Luwes (Faculty of Computer Science and Engineering, Central University of Technology) and Dr Elizabeth George (Medical Research Council Clinical Trials Unit, University College London). I have also been supported by the Robert Frater Institute in the Faculty of Health Sciences.

Gender bias still rife in African Universities

Women constitute about 30% of student enrolment in African universities, and only about 6% of African professors are women. This is according to the chairperson of Gender Studies at the University of Cape Town, Prof Amina Mama.

Prof Mama was delivering a lecture on the topic “Rethinking African Universities” as part of Women’s Day celebrations at the University of the Free State (UFS) today.

She says the gender profile suggests that the majority of the women who work in African universities are not academics and researchers, but rather the providers of secretarial, cleaning, catering, student welfare and other administrative and support services.

She said that African universities continue to display profound gender bias in their students and staffing profiles and, more significantly, are deeply inequitable in their institutional and intellectual cultures. She said women find it difficult to succeed at universities as they are imbued with patriarchal values and assumptions that affect all aspects of life and learning.

She said that even though African universities have never excluded women, enrolling them presents only the first hurdle in a much longer process.

“The research evidence suggests that once women have found their way into the universities, then gender differentiations continue to arise and to affect the experience and performance of women students in numerous ways. Even within single institutions disparities manifest across the levels of the hierarchy, within and across faculties and disciplines, within and between academic and administrative roles, across generations, and vary with class and social background, marital status, parental status, and probably many more factors besides these”, she said.

She lamented the fact that there is no field of study free of gender inequalities, particularly at postgraduate levels and in the higher ranks of academics. “Although more women study the arts, social sciences and humanities, few make it to professor and their research and creative output remains less”, she said.

Prof Mama said gender gaps as far as employment of women within African universities is concerned are generally wider than in student enrolment. She said although many women are employed in junior administrative and support capacities, there continues to be gross under-representation of women among senior administrative and academic staff. She said this disparity becomes more pronounced as one moves up the ranks.

“South African universities are ahead, but they are not as radically different as their policy rhetoric might suggest. A decade and a half after the end of apartheid only three of the 23 vice-chancellors in the country are women, and women fill fewer than 30% of the senior positions (Deans, Executive Directors and Deputy Vice-Chancellors)”, she said.

She made an observation that highly qualified women accept administrative positions as opposed to academic work, thus ensuring that men continue to dominate the ranks of those defined as ‘great thinkers’ or ‘accomplished researchers’.

“Perhaps women simply make realistic career choices, opting out of academic competition with male colleagues who they can easily perceive to be systematically advantaged, not only within the institution, but also on the personal and domestic fronts, which still see most African women holding the baby, literally and figuratively”, she said

She also touched on sexual harassment and abuse which she said appears to be a commonplace on African campuses. “In contexts where sexual transactions are a pervasive feature of academic life, women who do succeed are unlikely to be perceived as having done so on the basis of merit or hard work, and may be treated with derision and disbelief”, she said.

She, however, said in spite of broader patterns of gender and class inequality in universities, public higher education remains a main route to career advancement and mobility for women in Africa.

“Women’s constrained access has therefore posed a constraint to their pursuit of more equitable and just modes of political, economic and social development, not to mention freedom from direct oppression”, she said.

Prof Mama concluded by saying, “There is a widely held agreement that there is a need to rethink our universities and to ensure that they are transformed into institutions more compatible with the democratic and social justice agendas that are now leading Africa beyond the legacies of dictatorship, conflict and economic crisis, beyond the deep social divisions and inequalities that have characterised our history”.

She said rethinking universities means asking deeper questions about gender relations within them, and taking concerted and effective action to transform these privileged bastions of higher learning so that they can fulfil their pubic mandate and promise instead of lagging behind our steadily improving laws and policies.
