As the University of the Free State (UFS) continues to celebrate the achievements of its graduates during the April 2025 graduation ceremonies, three academic staff members from the UFS Faculty of Economic and Management Sciences (EMS) are among those marking a significant milestone with the successful completion of their doctoral degrees.

Prof Philippe Burger, Dean of the EMS Faculty, reflected on the significance of the moment and applauded the trio of new EMS PhD graduates: Dr Shaun Watson, Dr Marese Lombard, and Dr Ambrosé Ray du Plessis.

“For the EMS Faculty to have three staff members obtain a PhD on one day is very special,” Prof Burger said. “These colleagues have grown their standing in the scholarly community and are now, with a PhD in the bag, ready to take on the academic world and the world at large. The EMS Faculty places a high premium on our staff holding a PhD, so we strongly encourage those who are not in possession of a PhD to pursue one.”

Prof Burger added that their achievements not only reflect personal dedication and professional growth but also contribute to the University of the Free State’s Vision 130 goal: to have 75% of academic staff holding doctoral degrees by 2034.

The EMS academics who graduated during the April 2025 ceremonies are:

 

Dr Shaun Watson: Understanding markets through restatements

Dr Shaun Watson, a senior lecturer in the UFS School of Accountancy since 2006, earned his PhD in Management Accounting with a thesis titled ‘Market Efficiency and Share Price Reaction Following the Retrospective Restatement of Financial Statements of JSE-Listed Companies’. His study analysed how financial restatements affect market behaviour, providing key insights for policymakers and investors navigating emerging markets.

“For me, it was both a personal challenge and a professional goal,” Dr Watson said. “I’d often wondered if I had what it takes to complete a PhD and, as an academic, I saw it as the pinnacle of our field. My wife was the one who told me to ‘Nike – just do it!’ Her belief in me, along with the quiet support of my family, gave me the push I needed to start, and the strength to keep going.”

To those still considering the journey, Watson offered this advice: “Do it for yourself – because if you don’t, you will never finish. It is a demanding journey that requires sacrifice and perseverance, but the reward of discovering something meaningful is worth every moment.”

 

Dr Marese Lombard: Taxation as a tool for sustainable agriculture

Also from the School of Accountancy, Dr Marese Lombard received her PhD in Taxation. Her research, ‘Taxation as a Method to Promote Sustainable Agriculture in South Africa’, is the first of its kind to offer empirical evidence on how tax provisions could be used to incentivise sustainability in local agriculture.

“I hope to see a conversation regarding policy changes as to how taxation can be used as a positive method to impact sustainability,” Dr Lombard said. “If taxation can be used to further assist our agricultural industry to become more sustainable, it can not only increase our competitive edge but also address the concern of food security.”

Reflecting on her personal growth, she said, “It has taught me that we are more resilient than we think. The challenge of taking on a PhD has made me more open to other ideas and approaches, and more comfortable with criticism – not just in academia, but in life.”

 

Dr Ambrosé Ray du Plessis: Rethinking the political-administrative divide

From the Department of Public Administration and Management, Dr Ambrosé Ray du Plessis earned his PhD in Public Administration and Management. His thesis, ‘The Political-Administrative Dichotomy in Coalition-Led Metropolitan Municipalities: A South African Perspective’, developed a fresh conceptual framework for understanding the tensions and complexities within coalition-led governance, using the City of Johannesburg as a case study.

“For me, academia is a calling, and I believe that a PhD is an essential stepping stone to be successful in academia,” Dr Du Plessis said. “Being the first in my family to do a PhD motivated me to work harder, as I wanted to inspire those who will come after me.”

Balancing full-time lecturing and doctoral research required immense discipline: “I often had to work at night and over weekends to meet my deadlines… but the emotional and intellectual support from my PhD promoter, Prof Liezel Lues, was central to my success.”

Now, Dr Du Plessis hopes to deepen academic discourse on coalition politics: “My research addresses critical gaps and provides fresh insights into the political-administrative discourse as it can be applied to real-world coalition government problems in South Africa… I hope my work can leave a lasting impact – not only within academia but also in practical applications that benefit society.”

 

A testament to resilience and purpose

While their research topics differ vastly, all three describe their PhD journeys as transformative, both professionally and personally. From late nights and weekend writing sessions to intense supervision relationships, each story reflects a deeper commitment to scholarship – and to growing the UFS’s intellectual capital.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
