Unique PhD Journeys

On the left is Dr Modeni Sibande, who is looking forward to ensuring that Public Administration and Management remains relevant to contemporary evolving issues in society. On the right is Dr Maréve Biljohn, who as a student has always shown commitment to do her best in every aspect of her PhD journey.

In nature, one often comes across cool and surreal phenomena. Experiencing rare happenings in the academia is an altogether different encounter. One that Prof Liezel Lues, Professor in the Department of Public Administration and Management at the University of the Free State (UFS), explains as winning the lottery.

Two of Prof Lues’ doctoral students – representing two different institutions – graduated in 2018. Four years later, on the exact same date, 1 March 2022, Drs Maréve Biljohn and Modeni Sibanda will take up their new positions, respectively as Head of the Department of Public Administration and Management at the UFS and Head of the Department of Public Administration at the University of Fort Hare.

 

Social innovation and service delivery

Dr Biljohn, currently Senior Lecturer in the department, did her thesis on the topic: Social innovation and service delivery by local government: a comparative perspective. With work experience in local government, Dr Biljohn had a good idea of the problems that underpin poor service delivery in this sphere of government.

Public participation in integrated development planning: a case study of Buffalo City Metropolitan Municipality, was the title of Dr Sibanda’s thesis. The study revealed how individuals and communities navigate forms of power and raise the critical consciousness of municipal residents, communities, and public officials.

According to Dr Sibanda, his study was motivated by the need to explore how public participation power dynamics influence Integrated Development Planning outcomes.

He believes by doing so, the complexity of how individuals and communities navigate forms of power in public participation platforms and spaces would be unravelled. Unravelling such public participation power dynamics, he says, would raise critical consciousness and address and challenge visible, hidden, and invisible forms of power on these public platforms and spaces. “Often public participation platforms and spaces neglect and ignore the capacity of such spaces to manage the pervasive, complex power dynamics among stakeholders in municipal strategic development planning processes. This focus to my PhD therefore sought to fill that knowledge gap,” adds Dr Sibanda.

Prof Lues says the value link to their research is buoyed in the South African Local Government. “They have both established a niche area that addresses the challenges South African municipalities face,” she adds.


“There is no doubt that they are suitable for the position of head of department at this point.”


Achieving a coveted status in their careers

On experiencing this unique journey, Prof Lues says: “Of all the relations, a relation between a promoter and a student is the most inspiring and admirable one. Any promoter takes the utmost pride when his/her taught students achieve coveted status in their respective careers. To me, it feels like winning the lottery – twice.”

What do diamonds, chocolates, bugs and almost 30 Nobel Prizes have in common? Crystallography
2014-10-15

 

Some of the keynote speakers and chairpersons at the third world summit in the International Year of Crystallography (in Africa) were, from the left, front: Profs Abdelmalek Thalal (Morocco), Prosper Kanyankogote (University of Kinshasa, Democratic Republic of the Congo); Habib Bougzala (Tunisia), Santiago Garcia-Granda (IUCr, University Oviedo, Spain), Michele Zema (IYCr 2014, Italy/UK) and Dr Jean-Paul Ngome-Abiaga (UNESCO, Paris, France); back: Dr Thomas Auf der Heyde (Acting Director-general, South African Department of Science and Technology); Dr Petrie Steynberg (SASOL) and Prof André Roodt (UFS, host).

The third world summit in the International Year of Crystallography (in Africa) was hosted by Prof André Roodt, Head of the Department of Chemistry and President of the European Crystallographic Association,  at the University of the Free State in Bloemfontein.

A declaration with and appeal to support crystallography and science across Africa, was signed.

When one mentions 'Crystallography', or more simply 'crystals', what comes to mind? Diamonds? Perhaps jewellery in general? When thinking of crystals and Crystallography, you will need to think much bigger. And further – even to Mars and back.

Crystallography refers to the branch of science that is concerned with structure and properties of crystals. The obvious examples would include cut diamonds, gemstones such as amethysts, and ‘simple’ crystals such as selenite and quartz.

But have you thought about the irritating brown scales at the bottom of your kettle? The sand in your shoes? The salt over your lamb chops or the sugar in your coffee? All crystals. From egg shells to glucose, from bugs and insecticides to additives in food – even the compounds in chocolate – all fall under the close scrutiny of Crystallography.

The breakthroughs this field of science has produced have led to almost 30 Nobel Prizes over the years.

Determining the structure of DNA by crystallography was arguably one of the most significant scientific events of the 20th century. Different diseases have been cured or slowed by medicines obtained based on crystallographic studies. These include certain cancers, HIV/Aids, Tuberculosis and Malaria. Biological Crystallography enables the development of anti-viral drugs and vaccines.

This field of science influences our daily lives in virtually immeasurable ways. Here are but a few areas of study and development Crystallography contributes to:

•    LCD displays;
•    cellular smartphones;
•    insects and insecticides;
•    additives and products in foods;
•    improved effectiveness and security of credit cards;
•    new materials to preserve energy;
•    better gasoline with less by-products;
•    identify colour pigments used in paintings from the old masters, indicating if it’s an original or an imitation; and
•    beauty products such as nail polish, sun-block, mascara and eye shadow.

Crystallography is also currently used by the Curiosity Rover to analyse the substances and minerals on Mars.

Crystals and Crystallography form an integrated part of our daily lives – from bones and teeth to medicines and viruses, from chocolates to the blades in airplane turbines. Even down to the humble snowflake.
