The superpowers of women scientists at the UFS

The University of the Free State (UFS) has implemented several interventions to increase the diversity of its researchers, including its women scientists. Actions have paid off and resulted in an increase in the percentage of rated female researchers, from 27% in 2016 to 34% in 2021.


The university is also host to a number of science leaders in the six National Research Foundation (NRF)-funded South African Research Chairs Initiative (SARChI). Four of these research chairs are held by women. These are the research chairs in Vector-borne and Zoonotic Pathogens; Disease Resistance and Quality in Field Crops; Higher Education and Human Development; and Pathogenic Yeasts.

Health, medicine, and food sustainability are but three examples of areas in society where the women of the UFS is playing a critical role in science today.

In celebration of the International Day of Women and Girls in Science instituted by the United Nations General Assembly on 22 December 2015, the UFS is honouring its women scientists.

The science of science expos

One of the researchers at the UFS who is using science to make a difference in the lives of learners in our country, is Dr Angela Stott, Researcher and Teacher Educator in the Division of Social Responsibilities Projects (SRP) on the UFS South Campus. Together with colleagues in the SRP, she is involved in numerous Maths and Science outreach interventions to teachers and learners.

Science becomes fun for learners through the different initiatives created by Dr Stott and her colleagues. These include the online Learn Science programme (a brainchild of Dr Stott), using tablets donated by ioT.nxt, and the Creative Clubs intervention started by Dr Joleen Hamilton, a colleague of Dr Stott. In the latter, learners can take part in a MathArt competition and coding sessions.

In this year’s Creative Clubs projects, 100 Grade 9 learners from township schools will be mentored to prepare science fair projects for participation in the Expo for Young Scientists.

But why all this hard work for an expo? For these learners, the expo is more than just a public platform to showcase excellence. According to Dr Stott, learners in South African township schools tend not to be stimulated in extracurricular programmes, since teaching in these contexts is typically restricted to exam training.

However, her research has shown that higher-achieving learners from contexts of poverty respond well to such programmes and gain valuable knowledge, skills, and values from them. “This year, 100 higher-achieving Grade 9 learners from township schools will benefit from this programme, and next year another 100,” she says.

She adds that literature on this subject points to the need for structure, while also supporting learners’ development of autonomy when mentoring a learner to produce a science fair project. Dr Stott explains that the online programme around which this year’s intervention is built, has been created in a manner informed by literature on what is most likely to work. “By us researching the process, we will improve our understanding of how to maximise the benefits and mitigate the weaknesses that learners from poverty gain from such participation. This knowledge could help improve the effectiveness of such programmes throughout the country, and in other parts of the world where similar conditions apply,” she says.

Fighting for stronger immune systems

An international student from Zimbabwe, Nakai Matongera, a PhD graduate in Plant Breeding in the Department of Plant Sciences on the Bloemfontein Campus, is playing a key role in food sustainability in Africa with her research. She is a maize breeder working at the Scientific and Industrial Research and Development Centre (SIRDC) in Harare, Zimbabwe.

The focus of her PhD thesis is on the development of high-yielding and nutrient-dense maize varieties enriched with provitamin A, zinc, and essential amino acids such as lysine and tryptophan.

“With my research, I aimed to develop zinc-enhanced maize varieties that have great potential to reduce zinc deficiency in maize-based developing countries in sub-Saharan Africa,” she says.

Matongera explains that zinc-enhanced hybrids were developed by crossing introduced zinc donors and locally adapted maize inbred lines from three nutritional categories (normal, provitamin A, and quality protein maize (QPM). The hybrids were evaluated for both agronomic and nutritional performance under optimum drought and low nitrogen conditions.

“Results indicated that zinc-enhanced QPM hybrids accumulated high zinc under all growing conditions. However, the zinc-enhanced normal hybrids had the highest yield potential, implying dilution effects.”

“I find my research rewarding, because this biofortification strategy to combat micronutrient deficiency is cost-effective and has wide coverage and sustainability compared to other strategies such as clinical supplementation and food fortification,” says Matongera.

The outcomes of her research will one day, when it is implemented, change the lives of thousands of children in Africa who are suffering from zinc and iron deficiency. The shortage of zinc and iron in their diets affects their cognitive development as well as their immune systems, making them susceptible to a number of illnesses, including diarrhoea.

According to Prof Maryke Labuschagne, Nakai’s supervisor for her PhD study, this research will have a practical impact in Africa, as it will contribute towards the nutritional value of food.

Saving generations of humans and animals

When she could not pursue her childhood dream of becoming a vet, Dr Nthatisi Nyembe forged a new path in zoology, and today she is working in the Department of Zoology and Entomology on the UFS Qwaqwa Campus, where she focuses on veterinary parasitology.

Dr Nyembe’s research looks at the treatment and epidemiology of parasitic diseases in animals and humans, because – as she says – if animals are healthy, then humans are healthy. She says the ripple effect could save generations to come. “I want to be remembered for creating a drug that will make life easier for animals, because if animals are healthy, then the food we consume will also be healthy,” she says.

Dr Nyembe completed her studies on the Qwaqwa Campus from undergraduate to master’s level, specialising in Zoology. She was then awarded a scholarship to complete her PhD studies in Japan, where she spent four years looking into creating compounds that can treat and prevent unwanted parasites in animals, with a specific focus on mice.

“If I can get to a point where I can find one compound that has various benefits on multiple micro-organisms, then I will be happy”, she says.

While acknowledging the wide gender gap that still persists in her field of science, Nyembe says it should not hinder young girls who are interested in pursuing all levels of science.

“Society still looks down on girls and women, especially in Africa. If I go to a farmer as a woman and try to advise them about animal health, very few of them are receptive. However, the majority believe that I need to come with a man in order to be taken seriously. I just want to tell young aspiring female scientists that it is possible.”

“Whatever you put your mind to, you can pull through and achieve. Don’t allow yourself to be intimidated.”

True leadership may mean admitting disunity
 

In this edited extract from the inaugural King Moshoeshoe Memorial Lecture at the University of the Free State, Professor Njabulo S Ndebele explores the leadership challenges facing South Africa

RECENT events have created a sense that we are undergoing a serious crisis of leadership in our new democracy. An increasing number of highly intelligent, sensitive and committed South Africans, across class, racial and cultural spectrums, confess to feeling uncertain and vulnerable as never before since 1994.

When indomitable optimists confess to having a sense of things unhinging, the misery of anxiety spreads. We have the sense that events are spiralling out of control and that no one among the leadership of the country seems to have a definitive handle on things.

There can be nothing more debilitating than a generalised and undefined sense of anxiety in the body politic. It breeds conspiracies and fear.

There is an impression that a very complex society has developed, in the last few years, a rather simple, centralised governance mechanism in the hope that delivery can be better and more quickly driven. The complexity of governance then gets located within a single structure of authority rather than in the devolved structures envisaged in the Constitution, which should interact with one another continuously, and in response to their specific settings, to achieve defined goals. Collapse in a single structure of authority, because there is no robust backup, can be catastrophic.

The autonomy of devolved structures presents itself as an impediment only when visionary cohesion collapses. Where such cohesion is strong, the impediment is only illusory, particularly when it encourages healthy competition, for example, among the provinces, or where a province develops a character that is not necessarily autonomous politically but rather distinctive and a special source of regional pride. Such competition brings vibrancy to the country. It does not necessarily challenge the centre.

Devolved autonomy is vital in the interests of sustainable governance. The failure of various structures to actualise their constitutionally defined roles should not be attributed to the failure of the prescribed governance mechanism. It is too early to say that what we have has not worked. The only viable corrective will be in our ability to be robust in identifying the problems and dealing with them concertedly.

We have never had social cohesion in South Africa — certainly not since the Natives’ Land Act of 1913. What we definitely have had over the decades is a mobilising vision. Could it be that the mobilising vision, mistaken for social cohesion, is cracking under the weight of the reality and extent of social reconstruction, and that the legitimate framework for debating these problems is collapsing? If that is so, are we witnessing a cumulative failure of leadership?

I am making a descriptive rather than an evaluative inquiry. I do not believe that there is any single entity to be blamed. It is simply that we may be a country in search of another line of approach. What will it be?

I would like to suggest two avenues of approach — an inclusive model and a counter-intuitive model of leadership.

In an inclusive approach, leadership is exercised not only by those who have been put in some position of power to steer an organisation or institution. Leadership is what all of us do when we express, sincerely, our deepest feelings and thoughts; when we do our work, whatever it is, with passion and integrity.

Counter-intuitive leadership lies in the ability of leaders to read a problematic situation, assess probable outcomes and then recognise that those outcomes will only compound the problem. Genuine leadership, in this sense, requires going against probability in seeking unexpected outcomes. That’s what happened when we avoided a civil war and ended up with an “unexpected” democracy.

Right now, we may very well hear desperate calls for unity, when the counter-intuitive imperative would be to acknowledge disunity. A declaration of unity where it manifestly does not appear to exist will fail to reassure.

Many within the “broad alliance” might have the view that the mobilising vision of old may have transformed into a strategy of executive steering with a disposition towards an expectation of compliance. No matter how compelling the reasons for that tendency, it may be seen as part of a cumulative process in which popular notions of democratic governance are apparently undermined and devalued; and where public uncertainty in the midst of seeming crisis induces fear which could freeze public thinking at a time when more voices ought to be heard.

Could it be that part of the problem is that we are unable to deal with the notion of opposition? We are horrified that any of us could be seen to have become “the opposition”. The word has been demonised. In reality, it is time we began to anticipate the arrival of a moment when there is no longer a single, overwhelmingly dominant political force as is currently the case. Such is the course of history. The measure of the maturity of the current political environment will be in how it can create conditions that anticipate that moment rather than seek to prevent it. We see here once more the essential creativity of the counter-intuitive imperative.

This is the formidable challenge of a popular post-apartheid political movement. Can it conceptually anticipate a future when it is no longer overwhelmingly in control, in the form in which it is currently, and resist, counter-intuitively, the temptation to prevent such an eventuality? Successfully resisting such an option would enable its current vision and its ultimate legacy to our country to manifest in different articulations, which then contend for social influence. In this way, the vision never really dies; it simply evolves into higher, more complex forms of itself. Consider the metaphor of flying ants replicating the ant community by establishing new ones.

We may certainly experience the meaning of comradeship differently, where we will now have “comrades on the other side”.

Any political movement that imagines itself as a perpetual entity should look at the compelling evidence of history. Few movements have survived those defining moments when they should have been more elastic, and that because they were not, did not live to see the next day.

I believe we may have reached a moment not fundamentally different from the sobering, yet uplifting and vision-making, nation-building realities that led to Kempton Park in the early ’90s. The difference between then and now is that the black majority is not facing white compatriots across the negotiating table. Rather, it is facing itself: perhaps really for the first time since 1994. Could we apply to ourselves the same degree of inventiveness and rigorous negotiation we displayed leading up to the adoption or our Constitution?

This is not a time for repeating old platitudes. It is the time, once more, for vision.

In the total scheme of things, the outcome could be as disastrous as it could be formative and uplifting, setting in place the conditions for a true renaissance that could be sustained for generations to come.
