Opinion article by Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State.


South Africa is in trouble. No matter what your political or ethical persuasion – this much is abundantly clear. And if some of the opinions expressed lately by prominent economists are anything to go by, many are losing faith in whether we can still turn around a downward economic trajectory. 

 

But before we make up our minds either way, it is important to first face a truth that lies at the core of it all:  It is impossible to build a thriving economy on the back of a divided society. This makes societal reform a logical departure point for any economic relief efforts.  

And here the higher education sector has a definite and vital role to play.

On the battlefield of unexpected calamities, the South African economy can be compared to a soldier who has taken too many hits.  First, the devastating impact on so many sectors of our society caused by COVID-19 lockdowns and restrictions; followed by the question over misspent or missing pandemic support funds; and then the final agonising blow – the looting and destruction in Gauteng and KwaZulu-Natal in July, leaving a gaping hole of around 50 billion rand in damages

Equally heart-breaking and disconcerting as the physical damages and loss of life, is the damage caused to our nation’s psyche, with racist and classist fault lines reappearing, fuelled by the divisive rhetoric of unscrupulous leaders.
Looming ominously over this crowded battlefield, are the murky clouds of corruption at the highest level and of the most disturbing kind, which have been systematically and painfully laid bare by the Zondo Commission over the past three years.

We truly find ourselves at a very low point as a nation. Financially, morally, and mentally.

And, like all other sectors of society, higher education needs to ask itself what it can do – if anything – to help fix what is broken. 

Changing role of universities

Universities used to have a rather narrow focus on education and the creation of new knowledge. This role has, however, evolved considerably over the past decade or two. Their function nowadays is very much a societal one, where the focus on using skills and knowledge to make a real difference in the societies they serve and draw their students from – the engaged university.  

Let’s be clear: Higher education cannot solve poverty and inequality. That is the domain of government, which needs to ensure that appropriate policies are in place that will constructively stimulate investment and assistance from the private sector and industry.

The higher education sector needs to focus on its strengths. And that is to do research; to offer advice and come up with possible solutions; to educate and to provide skills that will help uplift individuals, families, and communities.

In short: universities need to deliver graduates who will ultimately build a better society, and through engaged scholarship change the lives of people. 

What has become abundantly clear, though, is that education alone is not enough. The corruption implications and moral dilemmas that many of our highly qualified politicians and leaders are embroiled in, prove that more is needed than just academic aptitude. 

The purpose of universities should therefore not only be to deliver good workers or thinkers. Universities need to deliver good citizens. Citizens that possess unshakeable values and ethics, enabling them to become good leaders.

During a recent 2021 University of the Free State Thought-Leader webinar titled Is South Africa falling apart – where to from here? panellists stated that the role of universities is to create a culture of active citizenry, to play a part in the holistic transformation of society, to ensure the sharing of research and discoveries, and to ensure inclusive academic excellence. These are no small feats and something higher education institutions should strive for.  

Creating a new generation of leaders

While young people spend time on university campuses, it is vital that – along with academic knowledge – universities educate them about the norms and values that form the bedrock of a healthy, thriving society. Not only teaching these values of social justice, respect, tolerance, and care – but also demonstrating how they find practical application.   
Universities should be microcosms of an ideal society, where respect for human rights and diversity, equality, and care underpin all our policies, communication, and interactions.

Universities should consistently use discourse platforms to promote these values and to speak out against things that threaten them, such as corruption, injustice, and prejudice in any form.

But once again, it goes further than that. Not only do we need to teach and encourage our students to speak out. We need to educate them on how to speak out. 

Unfortunately, so many of the student protest actions on our university campuses often fall short in this aspect, as valid concerns and demands are regularly overshadowed by disrespectful rhetoric, accompanied by unwarranted destruction of property and endangering lives. 

Recently, the University of the Free State had the opportunity to host a book launch by Helen Zille, the Federal Council Chairperson of the DA. Among the guests was EFF leader Julius Malema.

Afterwards, some Political Science students remarked how surprised they were to witness the very civil interaction between Zille and Malema – in the light of their very public political spats and differences.

And here lies an important lesson for our young South Africans: that there is a level of maturity that needs to be displayed if we want to take our country forward together. 

We can differ from someone – and passionately express our differences – but retain an atmosphere of tolerance and mutual respect. Our young leaders of tomorrow need to understand that, in the absence of such an atmosphere, reasonable negotiations become impossible, and they run the real risk of thwarting the very cause they are fighting for. 

Interconnectedness of our society

As much as higher education has a clearly defined role, it can only fulfil this role effectively if it is part of a well-functioning, larger system. |

As higher education, government, private sector, and industry, we are interconnected and unable to function properly in isolation.

Universities can, for example, teach young people the value of entrepreneurship and equip them with the necessary skills to contribute to the economy. But without an enabling environment created by government, policies, and commitment, as well as buy-in and support from industry, it all falls apart.

As much as I cannot thrive if my neighbour is suffering, we cannot rebuild our economy if we don’t acknowledge our interdependence and find new, innovative ways to collaborate to move ahead together.  

The age-old principles of ubuntu need to find a renewed, modern application in South Africa today. 

Involving our youth

Whatever form economic rescue efforts take, it must involve the young people of our country. Making decisions that will profoundly influence our youth without involving them in the process, is downright irresponsible. 

We simply cannot afford to alienate our leaders of tomorrow and then expect them to be ready to take over the baton and not repeat the mistakes of their predecessors.

At the University of the Free State, our student participation in university governance structures was at an all-time high of 70% last year. We see this as an important accomplishment – we hope to build on and expand this even further. In most of my dealings with our young leaders of tomorrow, I certainly get the impression that they are keen to make a positive contribution to our country. But they yearn for guidance, encouragement, and opportunities.  

‘Nothing about us without us’, is a slogan used widely in various contexts nowadays, with its roots tracing back to South African disability advocates in the 1980s. It is equally applicable to young people in our current South African predicament.

Our youth needs to be turned from apathy to active involvement. Without them, no economic ‘rescue efforts’ will have long-term sustainability. 

After all: it is their future that is at stake.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
