With coalition governments becoming more common in South Africa and proven to be unstable, a lecturer at the University of the Free State (UFS) devised an alternative contextual coalition-led framework towards a functioning political-administrative dichotomy. This instability adversely affects service delivery. 

The framework was devised by Dr Ambrosé du Plessis, lecturer in the UFS Department of Public Administration and Management, as part of his PhD research and focused on the City of Johannesburg Metropolitan Municipality. He hopes it can offer valuable lessons for the broader context of South Africa’s evolving political landscape, particularly in light of the 2024 national coalition-led Government of national Unity (GNU). 

Dr Du Plessis graduated with a Doctor of Philosophy with specialisation in Public Administration and management at the UFS April graduation ceremonies. Prof Liezel Lues, Professor of Public Administration and Management, in the Department of Public Administration and Management, was his supervisor. 

Dr Du Plessis is part of the newest cohort of the Emerging Scholar Accelerator (ESAP) mentoring programme for mostly lecturers who are less than five years post-PhD. This group falls within the Transformation of the Professoriate Mentoring Programme which aims to grow a critical mass of excellent emerging scholars at the university who are equipped to assume senior academic and research positions. 

 

Political-administrative dichotomy

With his thesis titled ‘The Political-Administrative Dichotomy in coalition-led metropolitan municipalities: A South African Perspective’, he focuses on the interface between politics and administration. Says Dr Du Plessis: “The political-administrative dichotomy discourse is unable to account for coalition politics in most of South Africa’s metropolitan municipalities. More importantly, political and administrative instability has become common in most of South Africa’s coalition-led metropolitan municipalities.

“What makes my research particularly interesting is that it transcends Public Administration by incorporating contributions from Political Science through critical discourse analysis. I also conducted interviews with political office-bearers, the South African Local Government Association in Gauteng province, as well as subject experts – both national and international – in public administration, political science, and constitutionalism, to uncover deeper nuances relating to local lived experiences and international perspectives,” says Dr Du Plessis. 

According to him, the increasing prevalence of coalition-led governments in South Africa’s metropolitan municipalities necessitates a reconceptualisation of the political-administrative interface. Traditional interpretations of the political-administrative dichotomy have proved inadequate in explaining the multifaceted and dynamic interactions characteristic of contemporary coalition governance. This study responds to that gap by proposing a nuanced, context-sensitive, and theoretically enriched framework that better reflects the realities of coalition-led metropolitan municipal governance in the South African context.

 

The findings of the research 

“Building on comparative and critical discourse analyses, this research advances a polychotomous framework – one that transcends mono-theoretical and discipline-bound approaches by integrating insights from Public Administration and Political Science. The framework acknowledges the existence of both formal and informal political-administrative relationships and interrogates how these configurations influence governance outcomes in coalition-led municipalities, with specific reference to the City of Johannesburg (CoJ) Metropolitan Municipality.

“The findings underscore the limitations of classical dichotomy theory, particularly in accounting for the intersectionality between coalition politics and the institutional architecture of local government. In contrast to the dichotomy discourse, which narrowly focuses on political principals and administrative office-bearers, this research situates the interface within a broader institutional and societal matrix that includes political parties, non-state actors, and citizen constituencies.”

Dr Du Plessis say although this study was confined to local government and the CoJ, he believes it makes a meaningful knowledge contribution with real-world impact, paving the way for continued exploration and innovation in both research and practice concerning the political-administrative interface in coalition-led metropolitan municipalities. “More importantly, I hope it sparks critical reflection on the central nervous system of government and governance in South Africa, highlighting the urgent need to reconfigure not only political and administrative arrangements, but also the broader governance frameworks required to manage coalition politics effectively.”

 

PhD journey 

Obtaining his PhD, Dr Du Plessis says, is extremely emotional as he hopes to have inspired the broader family and future generations of students. It is both a liberating and proud moment for him for which he is deeply grateful and extremely overjoyed. This is not only the achievement of a personal and academic goal, but also the fulfilment of a journey filled with perseverance, growth, and purpose.

Like most PhDs, his journey was characterised by challenges that not only tested his intellectual ability but also his drive to succeed. There were moments of “profound loneliness”, self-doubt and even an overwhelming sense of guilt and shame. He had to deal with mental health challenges and experienced the well-known imposter syndrome. However, the support from his wife, Natasha, and Prof Lues, as well as colleagues like Dr Marevé Biljohn, Head of the Department of Public Administration and Management, the Faculty of Economic and Management Sciences PhD support group under the leadership of Prof Tina Kotze and Mrs Igna du Plooy and the REAP programme under the leadership of Dr Henriette van der Berg and Dr Karen Booysen, were essential in completing his PhD. They guided him through the academic and emotional trials of this journey with unwavering compassion.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
