Prof Lizette de Wet
Prof Lizette de Wet is of the opinion that there is no gender distinction between what women and men could achieve in the field of Computer Science and Informatics.

“I consider obtaining my PhD while balancing my work, my marriage, and two young daughters (who did not sleep through before reaching age four!) as one of my biggest achievements,” says Prof Lizette de Wet, Associate Professor in the Department of Computer Science and Informatics at the University of the Free State (UFS).

Many firsts

Her achievements in the field include much more than the PhD referred to. On 11 February, International Day of Women and Girls in Science, the UFS celebrates her for pioneering the human-computer interaction (HCI) research environment, specifically the evaluation of usability and user experience in diverse application areas, where she has experienced and established many firsts.

Prof De Wet was one of the first students to complete a master’s degree in this discipline at UNISA (1994). She says the external examiner for her master’s was from the University of York in the UK, as expertise in South Africa was still lacking at the time.

In the Department of Computer Science and Informatics at the UFS, she established the HCI research area. This involved undertaking research projects in the discipline and developing curricula for a second-year module, an honours module, and a master’s module. 

“The second-year module was also one of two modules on campus to first use iPads in class to assist in a blended learning approach,” she says.

A woman’s contribution

Prof De Wet believes that in the research field of HCI, the focus is on the user and his/her overall user experience (including emotions, feelings, and competence) when using computers. “Taking the human being into consideration is much more important than simply concentrating on the programming code that needs to be written.”

Whether the human being writing the code is male or female, does not matter. Prof De Wet is of the opinion that there is no gender distinction between what women and men could achieve in the field of Computer Science and Informatics. 

“Although the students are still predominantly male, in the past few years more and more female students have enrolled for our postgraduate studies and completed it successfully, some of them with exceptional marks. In South-Africa, many women are making their mark in this discipline by being heads of departments at universities or in the private sector, by chairing national and international conferences, and by publishing ground-breaking research,” she adds.

Success with virtual reality

Over the past few years, Prof De Wet has concentrated on using brain-computer interfaces (BCIs) and virtual reality in her research. By the end of 2020, she had successfully supervised 11 master’s students and four PhD students, with one of the master’s students delivering ground-breaking research using virtual reality in the training of nursing students.

She elaborates: “The prototype involved virtually examining and evaluating a patient (with a foreign object lodged in a lung) in a virtual ward while wearing an Oculus Rift headset. The evaluation results were extremely positive and will be continued as a PhD study to investigate how to attempt to relieve motion sickness in an immersive virtual clinical simulation.”

Starting out as someone who never had the opportunity to lay her eyes on a computer during her school years, Prof De Wet is of the opinion that in South Africa – being a Third World country – there are numerous opportunities to make computers accessible to rural communities, and even to the large senior population who did not grow up with technology and might fear it.

With her passion for the profession, she not only delivers pioneering work, but also trains professionals in computer sciences who will contribute to a better tomorrow.

Position statement: Recent reporting in newspapers
2014-10-03

 

You may have read reports in two Afrikaans newspapers, regarding recent events at the University of the Free State (UFS). Sadly, those reports are inaccurate, one-sided, exaggerated and based not on facts, but on rumour, gossip and unusually personal attacks on members of the university management.

Anyone who spends 10 minutes on our Bloemfontein Campus would wonder what the so-called ‘crisis’ is about.

We are left with no choice other than to consider legal action, as well as the intervention of the South African Press Ombudsman, among other steps, to protect the good name of the institution and the reputation of its staff. No journalist has the right to launch personal and damaging attacks on a university and its personnel, whatever his or her motives, without being fair and factual. In this respect, the newspapers have a case to answer.

But here are the facts in relation to the reports:

  1. No staff member, whether junior or senior, is ever suspended without hard evidence in hand. Such actions are rare, and when done, are preceded by careful reviews of our Human Resource Policies, labour legislation and both internal and external legal advice. Then, and only then, is a suspension affected. A suspension, moreover, does not mean you are guilty and is a precautionary action to allow for the disciplinary investigation and process to be conducted, especially where there is a serious case to answer.
  2. At no stage was the Registrar instructed to leave the university; this is patently false and yet reported as fact. We specifically responded to the media that the Registrar does outstanding work for the university and that it is our intention for him to remain as our Registrar through the end of his contract in 2016.
  3. The Rector does not make decisions by himself. Senior persons, from the position of Dean, upwards, are appointed by statutory and other senior committees of the university and finally approved by Council. No rector can override the decision of a senior committee, and this has not happened at the UFS even in cases where the Rector serves as Chair of that committee. The impression of heavy-handed management at the top insults all our committee structures, including the Institutional Forum – the widest and most inclusive of stakeholder bodies at a university – which reports directly to Council on fairness and compliance of selection processes.
  4. In the case of senior appointments, Council makes the final decision. Council fully supports the actions taken on senior appointments, including a recent senior suspension. The fact that one Council member resigns just before the end of his term, whatever the real reason for this action, does not deter from the fact that the full Council in its last sitting approved the major staffing decisions brought before it. The image therefore that the two newspapers try to create of great turmoil and distress at the university, is completely unfounded.

Even if we wanted to, the university obviously cannot provide details about staffing decisions, especially disciplinary actions in process, since the rights of individuals should be protected in terms of the Human Resource Policies and procedures of the UFS. But that does not give any newspaper the right to speculate or state as fact that which is based on rumour or gossip, or to slander senior personnel of the university. For these reasons, we have been forced to seek legal remedy and correction as a matter of urgency.

Make no mistake, underlying much of the criticism of the university has been a distress about transformation at the UFS; in particular, the perception is created that white colleagues are losing their jobs. The evidence points in the opposite direction. Our progress with equity has been slow and we lag far behind most of the former white universities; that is a fact. More than 90% of our professors are white; most of our senior appointments at professorial level and as heads of department are still overwhelmingly white. Reasonable South Africans would agree that our transformation still has a long way to go and only the mean-spirited would contend otherwise. But based on the two Afrikaans newspaper reports, an impression is left of the aggressive rooting out of white colleagues.

In the past few years the academic standard of the university has significantly improved. We now have the highest academic pass rates in years, in part because we raised the academic standards for admission four years ago. We now have the highest rate of research publications, and among the highest national publication rate of scholarly books, in the history of the UFS. We have one of the most stable financial situations of any university in South Africa, with a strong balance sheet and growing financial reserves way beyond what we had before. We now attract top professors from around the country and other parts of the world, and we have the highest number of rated researchers, through the National Research Foundation, than ever before. And after the constant turmoil of a number of years ago, we now have one of the most stable campuses in South Africa. Those are the facts.

The UFS is also regarded around the world as a university that has become a model of transformation and reconciliation in the student body. The elections of our Student Representative Council are only the most visible example of how far we have come in our leadership diversity. Not a week goes by in which other universities, nationally and abroad, do not come to Kovsies to consult with us on how they can learn from us and deepen their own transformations, especially among students.

Rather than focus on what more than one senior journalist, in reference to the article in Rapport of 21 September 2014, rightly called ‘a hatchet job’ on persons and the university, here are the objective findings of a recent survey of UFS stakeholders: 92% endorse our values; 77% agree with our transformation; 78% believe we are inclusive; and 78% applaud our overall reputation index.  Those are very different numbers from a few years ago when the institution was in crisis.

This is our commitment to all our stakeholders: we will continue our model of inclusive transformation which provides opportunities for study and for employment for all South Africans, including international students and colleagues. We remain committed to our parallel-medium instruction in which Afrikaans remains a language of instruction; we are in fact the only medical school in the country that offers dual education and training in both Afrikaans and English for our students - not only English. We provide bursaries and overseas study opportunities to all our students, irrespective of race. And our ‘future professors’ programme is richly diverse as we seek the academic stars of the future.

We are not perfect as a university management or community. Where we make mistakes, we acknowledge them and try to do better the next time round. But we remain steadfast in our goal of making the UFS a top world university in its academic ambitions and its human commitments.
