The University of the Free State (UFS) is gearing up to be a leading academic institution in astronomical research. The institution successfully mounted a spectrograph with a polarimeter to the Boyden Observatory 1,5-m telescope that will provide scientists with visual access to both the Northern and Southern Hemispheres. 

The instrument, which can be accessed from Boyden, an astronomical research observatory and science education centre a few kilometres outside Bloemfontein, will allow researchers such as the Astrophysics Group at the UFS to do simultaneous polarimetry and spectroscopy of astronomical sources. This is vital for the research they are working on.

Mounting the spectrograph to the telescope and installing the polarimeter completed the upgrade of the 1,5-m telescope and is a leap forward for the astrophysics group at the UFS. The upgraded telescope with the spectropolarimeter, with a valued cost of R1.5 million, will also provide unique opportunities for collaborative research between the Astrophysics Groups at the UFS and researchers from the Appalachian State University (ASU). This adds greatly to the astrophysics research capacity at the university.
 
Prof Richard Gray, who 2019 started with the development of the astronomical spectrograph for the UFS Department of Physics, is a world-renowned expert in stellar spectroscopy, from the Department of Physics and Astronomy at ASU in North Carolina in the US. He was mainly responsible for the development and building of the instrument. 

Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, describes the moment that installation was completed as a feeling of enormous relief. “It took many hours of hard work, planning and testing to marry the 90-year 1,5-m telescope with the new sophisticated instrument,” he says. 

Adding value to graduate programme

Besides the development and installation of the spectrograph, Prof Gray also designed and built a polarimeter which can be integrated with the spectrograph. When placed inside the spectrograph, this piece of equipment transforms the spectrograph into a spectropolarimeter, giving it additional functionality. “This allows us, for example, to detect and analyse polarised light. It enables us to study the effect of magnetic fields in astronomical sources which introduce various polarisation signatures that can be detected with the polarimeter,” explains Prof Gray.

“I am fascinated by the polarimetric capabilities that we never had before. It is a great step forward,” remarks Prof Meintjes. 

“The Department of Electronics and Instrumentation at the UFS played an enormous role in the building of several components of the instrument that Prof Gray designed, as well as getting the 1.5-m telescope research ready so that the completed instrument could be mounted to the telescope”, says Prof Meintjes

He envisages that the research instrument will be ready for research purposes by March this year. Up till then researchers, graduates, and third-year students will have the opportunity to spend time on the spectrograph to familiarise themselves with it.

“Once installation is finalised, the UFS will be the only academic institution in South Africa with access to a 1.5-m telescope paired with a spectrograph. This gives us an edge in terms of our astrophysics programme and the training we provide our students. It also adds so much value to our graduate programme,” he says.

New instrument provides much flexibility

The spectrograph offers Prof Meintjes many possibilities for his research, and he is eager to put the instrument to use. To study binary systems as well as the jets of Active Galactic Nuclei (AGN), you need a spectrograph, preferably with polarimetric capabilities. It can also be applied to finding elements at the surface levels of stars so that their chemical composition can be determined.

“In the past, we needed to send our researchers to Sutherland and they were never guaranteed clear skies. Having this facility gives us so much flexibility,” he says.

Prof Brian van Soelen from the Department of Physics will be a key user of the spectrograph for his research. He is also playing an important role in terms of postgraduate training and research where the spectrograph is applied.

The polarimeter converts the spectrograph to a spectropolarimeter. This instrument, which is mounted on a telescope (in the case of the UFS, it is mounted on the Boyden 1,5-m telescope) enables the user to detect whether radiation from  astronomical objects are polarised and to analyse the level of polarisation of the  light. Scientists can then, for instance, study the effect of magnetic fields in astronomical sources, which introduce various polarisation signatures (typically with a characteristic  level of polarisation).

MBA Programme - Question And Answer Sheet - 27 May 2004
2004-05-27

1. WHAT MUST THE UNIVERSITY OF THE FREE STATE (UFS) DO TO GET FULL ACCREDITATION FOR THE MBA PROGRAMMES?

According to the Council on Higher Education’s (CHE) evaluation, the three MBA programmes of the UFS clearly and significantly contribute to students’ knowledge and skills, are relevant for the workplace, are appropriately resourced and have an appropriate internal and external programme environment. These programmes are the MBA General, the MBA in Health Care Management and the MBA in Entrepreneurship.

What the Council on Higher Education did find, was a few technical and administrative issues that need to be addressed.

This is why the three MBA programmes of the UFS received conditional accreditation – which in itself is a major achievement for the UFS’s School of Management, which was only four years old at the time of the evaluation.

The following breakdown gives one a sense of the mostly administrative nature of the conditions that have to be met before full accreditation is granted by the CHE:

a. A formal forum of stakeholders: The UFS is required to establish a more structured, inclusive process of review of its MBA programmes. This is an administrative formality already in process.

b. A work allocation model: According to the CHE this is required to regulate the workload of the teaching staff, particularly as student numbers grow, rather than via standard management processes as currently done.

c. Contractual agreements with part-time staff: The UFS is required to enter into formal agreements with part-time and contractual staff as all agreements are currently done on an informal and claim-basis. This is an administrative formality already in process.

d. A formal curriculum committee: According to the CHE, the School of Management had realised the need for a structure – other than the current Faculty Board - where all MBA lecturers can deliberate on the MBA programmes, and serve as a channel for faculty input, consultation and decision-making.

e. A system of external moderators: This need was already identified by the UFS and the system is to be implemented as early as July 2004.

f. A compulsory research component: The UFS is required to introduce a research component which will include the development of research skills for the business environment. The UFS management identified this need and has approved such a component - it is to take effect from January 2005. This is an insufficient element lacking in virtually all MBA programmes in South Africa.

g. Support programmes for learners having problems with numeracy: The UFS identified this as a need for academic support among some learners and has already developed such a programme which will be implemented from January 2005.

The majority of these conditions have been satisfied already and few remaining steps will take effect soon. It is for this reason that the UFS is confident that its three MBA programmes will soon receive full accreditation.

2. WHAT ACCREDITATION DOES THE UFS HAVE FOR ITS MBA PROGRAMME?

The UFS’s School of Management received conditional accreditation for its three MBA programmes.

Two levels of accreditation are awarded to tertiary institutions for their MBA programmes, namely full accreditation and conditional accreditation. When a programme does not comply with the minimum requirements regarding a small number of criteria, conditional accreditation is given. This can be rectified during the short or medium term.

3. IS THERE ANYTHING WRONG WITH THE ACADEMIC CORE OF THE UFS’s MBA PROGRAMMES?

No. The UFS is proud of its three MBA programmes’ reputation in the market and the positive feedback it receives from graduandi and their employers.

The MBA programmes of the UFS meet most of the minimum requirements of the evaluation process.

In particular, the key element of ‘teaching and learning’, which relates to the curriculum and content of the MBA programmes, is beyond question. In other words, the core of what is being taught in our MBA programmes is sound.

4. IS THE UFS’s MBA A WORTHWHILE QUALIFICATION?

Yes. Earlier this year, the School of Management – young as it is - was rated by employers as the best smaller business school in South Africa. This was based on a survey conducted by the Professional Management Review and reported in the Sunday Times Business Times, of 25 January 2004.

The UFS is committed to maintaining these high standards of quality, not only through compliance with the requirements of the CHE, but also through implementing its own quality assurance measures.

Another way in which we benchmark the quality of our MBA programmes is through the partnerships we have formed with institutions such as the DePaul University in Chicago and Kansas State University, both in the US, as well as the Robert Schuman University in France.

For this reason the UFS appreciates and supports the work of the CHE and welcomes its specific findings regarding the three MBA programmes.

It is understandable that the MBA review has caused some nervousness – not least among current MBA students throughout the country.

However, one principle that the UFS management is committed to is this: preparing all our students for a world of challenge and change. Without any doubt the MBA programme of the UFS is a solid preparation.
