The COVID-19 pandemic has created profound disruptions in our economy and society.  Due to the challenges of this pandemic, most universities have decided to move from face-to-face classes to online teaching (more accurately defined as emergency remote teaching and learning) so as to complete the 2020 academic year, and to prevent the spread of the virus.

Online learning is the result of careful instructional design and planning, using a systematic model for design and development.  With remote emergency teaching and learning, this careful design process is absent.  Careful planning for online learning includes not just identifying the content to be covered, but also how to support the type of interactions that are important to the learning process.  Planning, preparation, and development time for a fully online university course typically takes six to nine months before the course is delivered.

Emergency teaching and learning is a temporary shift of instructional delivery to an alternative delivery mode due to crisis conditions.  Hence, one cannot equate emergency remote teaching and learning with online learning, nor should one compare emergency remote teaching and learning with face-to-face teaching. What is crucial is the quality of the mode of delivery, and although assessment methodologies will differ between face-to-face teaching and remote teaching and learning, the quality of the learning outcomes should be comparable.

The financial model used in a South African (residential) university consists of three main income sources: (i) the state or government through a subsidy (the so-called ‘block grant’), (ii) tuition fees, and (iii) third-stream income (which is mainly a cost-recovery component from contract research, donations, and interest on university investments). The National Student Financial Aid Scheme (NSFAS) contributes to the tuition fees through a Department of Higher Education, Science and Innovation Bursary Scheme, providing fully subsidised free higher education and training for poor and working-class South Africans (recipients will typically be students from households with a combined income less than R350 k per annum).  

The negative impact of COVID-19 on the income drivers of the university can, and probably will, be severe.  Although the subsidy from the state or government can be ‘protected’ for a cycle of two to three years through the National Treasury, the pressure on income derived from tuition fees (that component which is not funded through NSFAS) will be increasing, as households would have been affected by the nationwide lockdown and with the economy in deep recession, a significant number of jobs would have been lost. The economic downturn, due to both COVID19 and a sovereign downgrade by all rating agencies, has already negatively impacted local financial markets as well as the global economy. The multiplier effect of this would be that the value of investments and endowments decreases (at the time of writing the JSE was still 20% down compared to the previous year), and philanthropic organisations and foundations will most probably reduce or even terminate ‘givings’ to universities.

Industry, private sector, and commerce will re-assess their funding to universities, whether for research or bursary support.  Overall, it is possible that the income sources for universities can be affected negatively in the short term, but it will definitely have longer-term implications on the financial sustainability of universities.  In this regard, it would be important for universities to perform scenario planning on the long-term impact of COVID-19 on the financial position of the university, and to adjust their strategic plans accordingly.

The major expense item in the university budget is the salaries of staff – this item is a fixed expense, particularly in the short to medium term. Hence, when introducing emergency remote teaching and learning, hence the switch to a different pedagogy and approach, university management did not have sufficient time to restructure the fixed cost part of the budget.  There are certainly other items in the budget which can be reduced, re-allocated or removed, and hence universities should, as a preliminary measure and based on their current financial position, develop a revised or adjusted 2020 budget.

The emergency remote teaching and learning therefore becomes an additional cost. These costs include, amongst others:
• training, development, and assistance to academic staff in converting content to a digital platform and learning management system (LMS),
• procuring data for staff (those who need to interface with the students) working from home,
• expansion of a call centre to guide and assist students,
• the cost of data for students through the reverse billing of data,
• procurement of digital devices (entry-level laptops) for students lacking such devices,
• paying for increased access to e-textbooks provided by publishers,
• payment for copyright clearance of additional material provided online to students,
• re-integration costs of students in terms of social distancing,
• improved hygiene on campus, disinfection of residences and other venues on campus, 360 degree screening (and testing) for the virus, the establishment of quarantine facilities, and the provision of appropriate personal protective equipment (PPE). 

Obviously, these costs need to be offset against the fact that residences were not used for some time, with a subsequent decrease in water and electricity usage and savings on catering in the residences.  It should, however, be argued that even if the students were absent from campus and the residences for some time, the salaries of all staff involved with particular functions in relation to residential students, as well as certain fixed and non-controllable costs,  still need to be paid.  When the offset has been assessed, the residual value, i.e. the additional cost, is still a substantial cost to the university due to the implementation of emergency remote teaching and learning.

The question is: who will fund this cost?

The instinctive answer would be: the university.

I would argue that this cost should be borne by the university, the student, and the state (government).  This is a crisis – a global crisis of unprecedented proportions, and in this moment of restrictions on movement, telecommuting, and social distancing, working together is essential to overcome this crisis. Student agency is key, in that they would exhibit the will to positively influence their lives and the environment around them. This is what social justice and fairness are – contributing to the development path of the country.

Although it would be fair to assume that a rebate or pro-rated amount on the residence fees for students should be considered, it would not be an acceptable rationale to apply a rebate on tuition fees, as the 2020 academic programme will be delivered, albeit through a different mode, but ensuring the relevant and appropriate quality.  Furthermore, as indicated earlier, the higher education system will be impacted (at least financially) negatively in the short and medium term, and no country can afford a weak, non-functioning higher education system; hence a fiscal stimulus package from the state (government) would be crucial to assist the sector during the COVID-pandemic and beyond (in the short term).  South Africa has a highly differentiated higher education system, which is one of the legacies of our past history, and historically disadvantaged institutions will be affected the most during this pandemic.

COVID-19 is presenting unique challenges to universities globally, but it also provides us with an opportunity to be innovative, to improve social solidarity, and to co-create new ways of engagements among stakeholders for the greater good of society.  However, without a fiscal stimulus package from government, this pandemic can render our ‘differentiated’ higher education system a massive blow, which will be difficult to recover from.

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.
