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


For the past two years, students in tertiary institutions have had to negotiate the choppy waters of emergency online tuition. In February, thousands of students at universities across the country will be returning to the shores of face-to-face learning. But it will require a process of reconnection that may take time and will have to be guided sensitively, says Prof Francis Petersen.


It is a fact of life that, in so many spheres, one’s journey is often as memorable – sometimes even more so – than one’s experiences at a destination. The South African education context is no exception. Many of us grew up with stories of parents and grandparents expanding at length about their difficult journeys to school ‘back in the day’. Some of the details of what happened inside the classroom may have faded over time, but the journey often remains etched in memory. Journeys that tell of sacrifice, of braving harsh weather and long distances – often on foot. A great victory already lies, after all, in the mere process of getting somewhere. 

The Online Move

There is little doubt that online tuition was a vital lifebuoy for education during the pandemic and lockdown, and that it will form an increasingly important part of our future educational landscape. The huge digital divide that the move to online education has exposed, remains a most pressing concern that needs to be addressed urgently in order to ensure that students from all socio-economic sectors and both rural and urban environments can access online resources. 

One consequence of online learning that is maybe not deliberated as frequently, is that it has essentially eliminated the need for a journey – in this case, the physical journey to a tertiary education campus. Once again, this fact comes with many perceived advantages: no transport costs, no travelling time, no risk associated with moving out of one’s comfort zone. Provided you have access to sufficient resources and connectivity (a topic for another time!), and provided you have a safe home environment conducive to learning (which many of our students sadly lack), it has become incredibly easy and convenient to access education – anytime, anywhere, and at your own pace.

But there are some aspects that can become complicated in the absence of a physical journey. 

Because journeys imply a few things:

A Journey Requires a Deliberate Decision About a Destination

People go on journeys because they want to get somewhere. They decide where they want to end up and then take the steps necessary to get there. The physical journey to a place of learning, of course, also reflects a more figurative journey towards an envisaged career and a successful future.  

Over the past two years, students have often reported feeling as if they were ‘drifting’ in the online environment, not always sure where they were heading, feeling a bit lost and disconnected. Maybe part of the reason for this lies in the fact that they were not physically going anywhere.  Without this physical aspect of the journey, it can become difficult to plot yourself, and difficult to convince yourself that you are moving ahead and making progress.

A Journey Requires a Measure of Sacrifice

A journey also almost always implies sacrifice in some form. Whether it is getting up early to catch a train, a bus, or two taxis to university, incurring fuel costs or transport fees, or just strolling to class across campus from your residence – a successful journey requires discipline and planning. And it takes some form of sacrifice of time and resources. 

Which brings me to the next point: 
 
A Journey Requires Commitment 

It takes commitment to make those sacrifices needed to complete a journey. And in turn, sacrifice fuels commitment. As human beings, we tend to treasure those things that were hard to obtain, and we do our utmost to hold on to them. The opposite of ‘easy come, easy go’, is equally true. It is often just as easy for students to opt out of online learning sessions, as it is to access it. And this is where the problem sometimes lies: commitment is not really tested or strengthened. 

Gaining Courage from Fellow Travellers

Probably the most poignant aspect of the journey analogy, is the fact that it makes you aware of other travellers. The students treading the campus pavements with you, passing you in passages, walking with you into class, are a constant reminder that your journey is not a solitary one. Fellow travellers – and fellow students – reaching out to one another, sharing tips and experiences, make the journey easier for everyone. Interacting with others and knowing that we are not alone, is a vital part of what makes us human, what makes our journeys meaningful.

Dealing with Fear

Countless COVID-19 research projects from all over the world seem to point to one basic bottom line: the absence of physical interaction has taken a huge psychological toll on most of our students. However, psychologists working on our campuses report a significant increase in students seeking psychological help in the run-up to the restart of contact learning. They say some students find the prospect of returning to campus stressful and even terrifying. It is a move that will take them outside their new comfort zones. Many students relate how they have been living in an ‘artificial online world’ for the past two years – not only academically but socially too. Students who used to be very sociable have been spending their non-academic time behind screens too, engaged in gaming, streaming services, and social media. Two years was long enough to blur memories of what used to be normal. Long enough to entrench new habits – not all of them conducive to good mental health – which can take time to change. It was also long enough to desensitise students to what they really need and want.

Psychological Support for Students

The value of providing our students with different forms of psychological support during these unusual and uncertain times cannot be overemphasised. At the University of the Free State (UFS), the various support initiatives we have implemented and expanded over the past two years have undoubtedly contributed to the fact that we could complete the academic years of 2020 and 2021 successfully. Among these initiatives are a 24-hour toll-free mental-health careline as well as an e-mentoring programme that offers socio-emotional support to students. Data analytics revealed that more than a third of our students engaged in these support interventions, and we see it as a major reason that, despite all the obvious challenges, we still managed to improve our overall institutional success rate in 2020 and 2021.  

Social Interaction a Basic Need

As tertiary institutions, we need to not only focus on what is convenient for our students at this time, but on what they actually need. And as human beings, we need social interaction. We need to read social cues, expressions, and body language, hear voice intonation, and where possible and appropriate, touch and feel. University life is, after all, about so much more than just attending classes. It is about engaging in sporting and cultural activities, about honing your interests, and finding new ones. It is about learning to collaborate and building networks and support groups, about forming friendships, and entering relationships. And sometimes, it is about just having fun.

Returning to Campus

Most universities are currently introducing some form of blended learning programme, combining online and face-to-face tuition. At the UFS, 67% of our modules on offer will be in a face-to-face format (at least in the early part of 2022), with the necessary COVID-19 protocols in place to ensure a safe environment for staff and students. As we welcome our students back on campus, it is vital that we as university leadership carefully and effectively remind them that their study years should be a holistic experience, encompassing different aspects of their being. We should encourage them to make use of the precious reconnection opportunities with those around them. And be patient as they negotiate their way in an old-but-new environment.

Let the journey begin.

A summary of an inaugural lecture delivered by Prof Robert Bragg at the University of the Free State:

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
