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.

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
