It is becoming increasingly difficult for institutions of higher learning in South Africa to maintain the delicate balancing act of finding sustainable funding solutions amid mounting pressures caused by rapidly altering learning and teaching environments, dwindling government subsidies, and the massification of higher education.  And uncontrolled, violent student protests might just be the final blow that sends many tertiary institutions over the precipice, says Prof Francis Petersen, Rector and Vice-Chancellor of the University of the Free State.

There is no doubt that student protests have over the years played a vital part in South Africa’s journey towards and maturation as a democracy. During the anti-apartheid struggle, student organisations such as NUSAS, SASO and later SASCO kept South Africa’s human rights violations on the international agenda through unrelenting campaigns and protests. And more recently, the #FeesMustFall movement in 2015 and 2016 has raised important awareness around ensuring access to education for students from the lowest-earning households. 

Transcending boundaries of legitimate protest

The recent spate of violent protests on some university campuses, however, seems to transcend the boundaries of what can rightfully be termed as ‘protest action’. When students at the University of KwaZulu-Natal (UKZN) and the Durban University of Technology (DUT) caused severe physical damage and disrupted classes at the beginning of the year, UKZN Vice-Chancellor, Prof Nana Poku, condemned their actions in no uncertain terms as ‘organised crime’. And he is right. This kind of behaviour is nothing but opportunistic criminality in the guise of legitimate protest. 

A few weeks after the violence erupted on campuses in KwaZulu-Natal, students on the University of the Free State (UFS) Qwaqwa Campus went on a similar rampage, throwing stones at protection officers, vandalising buildings, and raiding the university dining hall.   

There are distinct differences between these acts and the majority of past student protests.

Different issues

In most cases, current issues represent a much narrower interest than in the past, affecting only a certain section of the student population, and often revolving around the administrative processes concerning funding.  At UKZN, the main issue seems to have been students demanding to register even though they had historical debt. At the UFS Qwaqwa Campus, it was about a decision by the National Student Financial Aid Scheme (NSFAS) to pay accommodation allowances for students residing off campus directly to landlords and not to students themselves. Apart from affecting a relatively small number of students, the ‘fight’ was not per se with university management. Universities South Africa (USAf) pointed out that many of the issues raised by students this year were actually sector challenges and fell outside the control of tertiary institutions. Regardless of this, institutions regularly bend over backwards in an attempt to find workable interim solutions and making financial concessions to accommodate affected students. Prof Poku relates how at UKZN, the concessions made towards students with historical debts amounted to more than R1 billion. At the UFS, apart from similar concessions, we also offered students allowances for food and books amounting to more than R71 million this year, while they are waiting for their NSFAS subsidies to be released – a major impact on cashflow management. Despite these gestures of goodwill, a small group of aggrieved students still went ahead with violent acts, causing millions of rands of damage on campus and creating an atmosphere of intimidation and fear.  

Different environment 

University campuses today are vastly different spaces from what they used to be in the 1970s and 1980s, as a result of drastic and far-reaching changes in the educational landscape over the past few decades. Access to higher education has opened up and is no longer restricted to high-income households. The total number of students enrolled at higher education institutions increased by almost 70% between 2002 and 2020, growing to just more than one million in number. Coupled with that, tertiary institutions have gone through radical transformation processes, ensuring that they not only embrace diversity, but respect human rights and social justice through fair process and policy.

At the University of the Free State, for example, we have had well-considered, comprehensive transformation over several years in all spheres of operation, enabling us to become an institution where diverse people feel a sense of common purpose and where the symbols and spaces, systems and daily practices all reflect commitment to openness and engagement. We also have various initiatives to ensure that students are successful in their studies, ranging from tutorial programmes to language, writing, and psychological support.  Policies and structures are continuously being implemented and reviewed to embrace social justice in all its forms, with deliberate dialogue opportunities and avenues created for raising concerns and addressing them. At the UFS, student success is a social justice imperative.  Great care is also taken to involve our student leadership in governance on all levels, with a high level of student participation in all UFS governing structures. 

Despite all the different recourses available to them, and a genuine culture of participation and caring cultivated on our campuses, disgruntled splinter groups in the student body still routinely reach for the most destructive weapon in their arsenal of options, namely violent protests. These protest actions also often seem to jump the gun, as they happen in tandem with and despite fruitful, progressive negotiations with elected student leaders. Not only is this incredibly frustrating – it disrespects the rights and wishes of the overwhelming majority of students, and completely challenges the notion of ‘negotiation and engagement in good faith’. 

Wider ramifications

There are no winners in the wake of ill-considered, violent acts of vandalism. Offending students are no closer to a solution – in fact, they may find themselves suspended and in trouble with the law to boot. By disrupting classes and preventing access to campuses, they are effectively robbing their fellow students of the opportunity to work towards obtaining a qualification.  Affected institutions are impacted in their ability to provide quality education to students and in fulfilling their wider society-focused mandate. On top of that, potential donors and investors in the South African higher education sector are discouraged.

The sustainability and very survival of higher education institutions are ultimately at stake, as especially small and medium-sized universities simply cannot continue to bear the financial and operational burden that each violent protest brings. 

Tough reaction needed 

It has become necessary to take a tough stance against offenders who perpetrate senseless acts of violence and place students and staff members in danger on our campuses. At the UFS, we have always been very accommodating towards protesting students, not only as a constitutional right, but our approach in dealing with student misconduct has a strong element of restorative justice.  But we have decided to take a hard-line approach against the offenders in these latest acts of violence and destruction – opposing bail and instituting emergency disciplinary processes against them, resulting in immediate suspensions and sanctions which could lead to expulsion. We need to send a clear message that blatant acts of criminality will simply not be tolerated on university campuses.

We also appeal to political parties under whose banners many of these destructive activities are undertaken, to publicly condemn these acts and to call their members to order.

Respect a vital part of curriculum 

Throughout the course of history, we have come to associate university campuses with arenas where free speech is encouraged, and social ills are pointed out. This role should be cherished, continued, and encouraged – ‘reclaiming’ back the university campuses as spaces for discourse.  But equally important is the responsibility to use your right to freedom of expression in such a way that you do not violate the rights of other individuals or jeopardise the continued operation of the very institution you all form part of – and by implication, negatively affecting the wider interests of the society it serves. 
 
The role of universities is, after all, not only to provide good workers and innovative thinkers for the job market. We need to cultivate good citizens, who can make a meaningful difference to society. Teaching and encouraging mutual respect should be a vital part of any university curriculum. By letting criminality go unpunished and not speaking out to these acts, we are contributing towards a culture of entitlement, where people readily resort to criminal acts when they do not get what they believe they are entitled to. This cuts directly across what institutions for higher learning aim to achieve and bodes for a dangerous future.

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.
