GLS explores global view on gender and intersectionality
Students share their views on hard- hitting global issues

Race, gender, and inequality, a sharp focus in modern society, was discussed at the first session of day two of the Global Leadership Summit (GLS), on 10 July 2018. A panel discussion was led by Prof Ahmed Bawa, CEO of Universities South Africa and Prof Danie Brand, Director: Free State Centre for Human Rights at the University of the Free State (UFS).

Identity and gender issues important to youth
During the panel discussion, Dr Yvonne L Terrell-Powell from Edmond Community College, Seattle, in the US, spoke on the expectations put on first-generation students as they enter the higher education space. “In the United States when I was a student, in predominantly black universities, the expectation was to be involved in civic and political engagements, and not to only study.” Intersectionality was discussed and how identity is used as a criterion for exclusion, marginalisation and the perpetuation of all forms of “isms” and disregard of minority groups such as LGBTIQ+ communities. Other panellists included Pura Mgolombane, Dean of Student Affairs at UFS, Dr Vivienne Felix, Director: Experiential Learning, New York University, Margo Van Muylder, a student from the University of Antwerp, and Dr Segun Obadire, Director of International Relations at University of Venda.

Delegates were entertained by an Arts and Social Justice Theatre Production Psalm 69 and a play named Cosmology and Culture; Patriarchy. A dialogue on the play ensued between the audience and members of the cast who discussed abuse of women and the disabled, and the role of men, with experiences shared from a global perspective.

Reconciliation and transformation give hope
The second session commenced with a panel discussion on reconciliation and transformation titled “Stepping up and committing to change: A vision for the youth in terms of socio-economic reconciliation and transformation”. The session was moderated by Prof Francis Petersen, UFS Rector and Vice-Chancellor, alongside Dr Glen Taylor Senior Director: Research Development at UFS, with panellists from various sectors such as business, student leaders, human rights organisations and the Bloemfontein Business Chamber.
 
Ndaba Ntsele, Executive Chairman of Pamodzi Group and former UFS Council member and panellist spoke of the ability to overcome challenges that can hold one back. “You need to decolonise and detribalise yourself, see yourself first as a human being, never fear or feel that your background can hold you back.” Dr Glen Taylor, Senior Director: Directorate Research Development, spoke of the impact of research that is being produced at UFS. “Instead of the number of articles published, we need to ask what the impact is of our research in society.”

The summit is a joint programme between the UFS International Office, Student Affairs and the Institute of Reconciliation and Social Justice. It will continue with more panel discussions, robust engagements and more activities until 14 July. The programme includes an excursion to Kimberley and the Galeshewe township in Northern Cape. Delegates will have the opportunity to attend the annual Vrystaat Kunstefees/Free State Arts Festival which will be held on the Bloemfontein Campus from 10-14 July, as well as other African theatre productions.

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.
