The newly appointed editor of the University of the Free State(UFS) journal for humanities Prof Henning Melber had vowed to give the publication a deeper insight on critical issues ranging from decolonisation of knowledge to knowledge production.

In his first editorial opinion as the new Editor of the Acta Academica journal, Prof Melber said the publication has the declared intention to apply a critical social theory perspective.

“Dedicated to scholarship in the humanities, Acta Academica will henceforth be published annually with a minimum of two issues, plus an optional additional issues per year,” he said. 

Former Editor Professor Lis Lange, previously Vice-Rector: Academic at the University of the Free State (UFS), has moved to the University of Cape Town as Deputy Vice-Chancellor for Teaching and Learning.

The journal publishes scholarly articles that examine society, culture and politics from a critical social theory perspective and it is also interested on scholarly work that examines how the humanities in the 21st century are responding to the double imperative of theorising the world and changing it.

Analysis on Africa encouraged for Acta Academica

As a journal promoting humanist values and ethics, Prof Melber stated that he would like to see Acta Academica publishing scholarly analysis and think pieces that engage with such challenges in a critical (and gendered) theoretical perspective. 

“We welcome in particular contributions that link to current themes and processes on the African continent and especially to Southern Africa, without abandoning the global context and the shared perspectives of committed
scholarship elsewhere,” he said.

Decolonisation of knowledge

“We will promote an emphasis on contributions in the fields of post-colonial, development, cultural, gender, international and African Studies aiming to support current efforts towards a decolonisation of knowledge and knowledge production. 
He said the journal will combine an international post-colonial discourse inspired by critical theory and other relevant schools of thought applied to and/or generated in a local and regional (African) context. 

“We also welcome efforts to contribute to the decolonisation of knowledge, which still to a large extent is anchored in the global asymmetries. We cannot pretend these asymmetric power relations and inherited structures do not exist.  “Nor will we be able to avoid their reproduction completely. But we can promote ownership of authors over their intellectual product and will disseminate the work as widely as possible,” he said.

New Editor calls for diversification of knowledge


In another efforts to decolonise, Prof Melber said they would also make special efforts to empower aspiring African scholars. As part of this endeavour, the UFS’s Centre for Gender and Africa Studies has for several years, been the partner institution of Africa Spectrum for the annual Young African Scholars Award

“We will try to create similar opportunities, encouraging early career scholars to submit articles. In addition, we would like to expand the character of contributions, by further diversification of forms of knowledge transmission through debate articles, reports, comments, review essays and other thought-provoking interventions. We hope to receive your support, as potential authors or as readers who contribute to or benefit from Acta Academica’s efforts to further a stimulating debate,” he said

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.
