Global Social Innovation Indaba
Panel discussion during the 2024 Global Social Innovation Indaba held at the University of the Free State, Bloemfontein Campus.

Insightful, thought-provoking and inspiring: These were some of the words used to describe the 2024 Global Social Innovation Indaba, which took place at the Centenary Complex on the University of the Free State’s (UFS’s) Bloemfontein Campus from 30 September to 2 October 2024.

The three-day conference was hosted by the global Social Innovation Exchange (SIX) in collaboration with the UFS, under the theme ‘People Powered Change’. The conference brought together leaders and innovators from South Africa and several other countries, including Louise Pulford, CEO of SIX; Markus Lux, Senior Vice-President at Robert Bosch Stiftung, and Desmond D’Sa from the South Durban Community Environment Alliance (SDCEA), among others.

In her opening address, Acting UFS Vice-Chancellor and Principal Prof Anthea Rhoda welcomed the guests and described the conference as an opportunity to “deliberate, debate, and dissect ideas around the all-important topic of harnessing people-powered change in order to build successful societies”.

Powering social change

As part of the conference guests engaged in a series of panel discussions and activities, and attended presentations on various topics.

D’Sa was one of the first speakers, delivering a keynote address titled ‘An activist guide to people-powered change’. He referred to moments throughout his career in which he has actively worked towards change in his community and beyond, and highlighted some of the work the SDCEA continues to do. Guests were also treated to a spoken word performance by Napo Masheane, Artistic Director at the Performing Arts Centre of the Free State (PACOFS).

Advocate Tembeka Ngcukaitobi touched on several points in his talk, such as what the law meant or means to indigenous people. He explored this by referring back to the colonialist era. Ngcukaitobi, who described law as the most ubiquitous and most stable concept that European settlers brought, indicated that it was brought in two faces: the face of justice, and the face of violence. Therefore, he said, “… the future of law that has been most enduring is the ability of the law to transform itself from violence to justice.”

Guests said they regarded the presentations and dialogues as insightful, and also highlighted their appreciation for being able to interact with the campus itself. This sentiment in large part stemmed from the attendees being split into smaller groups and taken to see different parts of the campus. They also got to see an exhibition exploring the role of art in social justice at the Department of Fine Arts.

Lessons from the conference

The last day featured a panel discussion titled ‘Challenging power dynamics and redefining global exchange’, which included an engagement session with the audience. Guests were able to reflect on the information they had acquired at the conference and challenged themselves to continue working towards change and innovation.

“What I learnt from these three days is that since we all want to do the right thing, we all know what the job that needs to be done is,” said Michael Ngigi, CEO of Thinkplace Africa. “As such, we need to be bold in going for that, and really push back on the status quo that is formed by the places we represent.”

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
