Prof Loyisa Jita
Member of sixth Umalusi Council, Prof Loyiso Jita


Umalusi council members are appointed by the Minister of Education for their professional expertise in education and training. The council is formally mandated to research matters related to the sub-framework of qualifications responsible for the General and Further Education and Training qualifications. Prof Jita will be playing a governance role in Umalusi as an organisation.

Appointment a recognition of contribution to quality assurance systems

Sharing his sentiments on the appointment, Prof Jita said it was an affirmation of his dedication to delivering quality education in the country. “Being on the council is further recognition of one’s contribution to the quality assurance systems of the country and an elevation of the role in decision-making. The council, for instance, provides final approval of Grade 12 national results in public and private schools.”

He previously served on one of the Umalusi sub-committees responsible for assessment and standards, also known as the Grade 12 Standardisation Committee.

The sixth council will meet for the first time in September for induction and allocating specific roles to members.
 
Prof Jita joined the UFS in 2012. In 2014, the University of the Free State (UFS), in partnership with the South African National Roads Agency, launched the SANRAL Chair in Science, Mathematics, and Technology Education on the Bloemfontein Campus, and Prof Jita was appointed as the first SANRAL Chair. In 2017, he was appointed as Dean of Education.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
