Dr Jared McDonald
Prof Jared McDonald, Assistant Dean: Faculty of The Humanities at the University of the Free State, obtained his first National Research Foundation rating in the C2 category.

Obtaining his first National Research Foundation (NRF) rating has been the goal of Prof Jared McDonald, Assistant Dean: Faculty of The Humanities at the University of the Free State (UFS), since 2020 when he was selected for the UFS Transforming the Professoriate Mentoring Programme.

Prof McDonald obtained a C2 rating recently and credits the programme, under the leadership of Dr Henriëtte van den Berg, who provided invaluable support and mentorship, for this achievement. This rating recognises Prof McDonald as an established researcher and he may enjoy some international recognition for the quality and impact of his recent research outputs. 

“I am delighted to have received a C2 rating. I was hoping to obtain a C2, so when I received confirmation, it felt really good. Since being recruited to the Transforming the Professoriate Programme I have been focused on producing a series of quality journal articles, and importantly, my first monograph. At times it was a struggle to balance the demands of being Assistant Dean in the Faculty of Humanities along with my teaching responsibilities,” says Prof McDonald.

He says obtaining the rating would not have been possible without the interventions of the programme, which assisted him in securing funding for a sabbatical. The encouragement of colleagues and family was equally valuable in helping him to keep his eye on the goal.


Research 

As a nineteenth-century historian, Prof McDonald’s, who is an Associate Professor in the Department of History, research includes topics ranging from the London Missionary Society’s missions to the San as well as the role of controversial missionaries in influencing public discourse on the right to legal equality and social inclusion for indigenous subjects of the British Crown. Another topic is the ways in which evangelical-humanitarian discourse inadvertently provided the justification for the transfer of San children to Cape colonial society. 

“In my publications, the key actors, including Khoesan, are revealed to have been exercising agency in response to a social and political context that was not of their own choosing, but to which they had to respond. The contradictions of the period, coupled with the prospects for blurring the social boundaries of an otherwise strict hierarchical society, provided the means for social manoeuvre and options for resistance from within the confines of the colonial state. I am continuing to explore these ideas in a series of upcoming journal articles and book chapters,” he says. 

The pressure, says Prof McDonald, is already on to retain his rating, and hopefully improve it, when it comes up for review in five years’ time. He is currently working on his second monograph, which is a historical biography of a controversial, but fascinating, missionary who played a notable role in South African history in the early nineteenth century. “The worth of any historical biography lies in the biographer’s ability to shed light on the circumstances, contingencies, and contradictions that shaped the contours of the protagonist’s life, thus illuminating the historical context,” concludes Prof McDonald. 

He seeks to relate his research to his approach to teaching by exploring innovative ways of making the past relevant to students today. This is motivated by the conviction that the elucidation of possibilities of agency in the past raises the prospect for students to engage with the meanings and possibilities of agency in the present.

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.
