UFS unveiled new spectrograph
Assisting Prof Richard Gray with the installation of the spectrograph and the polarimeter were the Electronics and Instrumentation departments at both the UFS and the ASU. Left from the spectrograph, are from the left, front: Innes Basson, Head of the Department of Electronics and Instrumentation, Prof Pieter Meintjes, Senior Professor in the Department of Physics, Mark Jackson, Department of Electronics and Instrumentation, Hélène Szegedi, Lecturer in the Department of Physics, and Prof Richard Gray. At the right, from the spectrograph, front, are Natali Matchelt, master’s student, Izak van der Westhuizen, Lecturer in the Department of Physics; Barend Crous, Department of Electronics and Instrumentation; middle: Wian Smit, master’s student, Joleen Barnard, master’s student; back: Kobus Krüger, Department of Electronics and Instrumentation, Henri Roodt, Department of Electronics and Instrumentation; and Dr Hendrik van Heerden, Department of Physics.

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.

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).

Institutional research culture a precondition for research capacity building and excellence
2004-11-16

A lecture presented by Dr. Andrew M. Kaniki at the University of the Free State Recognition Function for research excellence

16 November 2004
The Vice Chancellor, Prof. Frederick Fourie
Deputy Vice Chancellors, Deans
Awardees
Colleagues and ladies and gentlemen

It is a great pleasure to be here at the University of the Free State. I am particularly honoured to have been invited to present this lecture at the First Annual Recognition Function for Research Excellence to honour researchers who have excelled in their respective fields of expertise. I would like to sincerely thank the office of the Director of Research and Development (Professor Swanepol), and in particular Mr. Aldo Stroebel for facilitating the invitation to this celebration.

I would like to congratulate you (the UFS) for institutionalizing “celebration of research excellence”, which as I will argue in this lecture is one of the key characteristics of institutional research culture that supports research capacity building and sustains research excellence.

Allow me to also take this opportunity to congratulate the University of the Free State for clocking 100 years of existence.

Ahmed Bawa and Johan Mouton (2000) in their chapter entitled Research, in the book: Transformation in higher education: global pressures and local realities in South Africa (ed. N. Cloete et. al Pretoria: CHET. 296-333) have argued that “…the sources of productivity and competitiveness [in the knowledge society and global economy] are increasingly dependent on [quality] knowledge and information being applied to productivity”. The quality knowledge they refer to here is research output or research products and the research process, which (research) as defined by the [OECD] Frascati Manual (2002: 30) is:

“…creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of man, culture and society, and the use of this stock of knowledge to devise new applications”

The South African Government has set itself the objective of transforming South Africa into a knowledge society that competes effectively in the global system. A knowledge society requires appropriate numbers of educated and skilled people to create quality new knowledge and to translate the knowledge in innovative ways. To this end a number of policies and strategies like the Human Resource Development [HRD] Strategy for South Africa, the National Plan for Higher Education (NPHE) and the South Africa’s Research and Development [R&D] Strategy, have highlighted human resource development and the concomitant scarce skills development as critical for wealth creation in the context of globalization. The key mission of the HRD Strategy for instance is:

To maximize the potential of the people of South Africa, through the acquisition of knowledge and skills, to work productively and competitively in order to achieve a rising quality of life for all, and to set in place an operational plan, together with the necessary institutional arrangements, to achieve this.

The R&D Strategy emphasizes that maximum effort must be exerted to train the necessary numbers of our people in all fields required for development, running and management of modern economies. Higher education institutions like the University of the Free State have a key role to play in this process, because whatever form or shape a university takes, it is expected to conduct research (quality research); teach (quality teaching – and good graduates); and contribute to the development of its community! Thus the NPHE states that the role of higher education in a knowledge-driven world is threefold:

Human resource development;

High-level skills training and

Production, acquisition and application of knowledge.

Quality research output or knowledge which as argued is critical in determining the degree of competitiveness of a country in the knowledge economy is dependent upon quality research (process). Both the process of producing quality research and its utilization cannot and does not happen in a vacuum. It requires an environment that facilitates the production of new knowledge, its utilization and renewal. It requires skilled persons that can produce new knowledge and facilitate the production of new skills for quality knowledge production. Such an environment or in essence a university must have the culture that supports research activity. Institution research culture (that is a conducive and enabling institutional research culture) is a precondition to research capacity building. Without an institutional research culture that facilitates the development and nurturing of new young researchers it is difficult, if not impossible for a university to effectively and efficiently generate new and more quality researchers. Institutional research culture is also necessary to sustain quality research and quality research output or research excellence. It facilitates the development and sustenance of the institutional and people capacities required to do research produce quality research and generally attain research excellence!

We do recognize that the patterns of information and knowledge seeking, and knowledge generation vary among field or disciplines. For example, we know that in the humanities knowledge workers often work individually, and not as collaboratively as do those of the sciences, they all however, require supportive environments – institutional research culture to achieve and sustain research excellence. An institution does not simply attain a supportive research culture, but as Patricia Clements (English Department, University of Alberta, Edmonton) in her presentation Growing a research culture argues, research culture has to be grown [and maintained]. It unifies all natural and engineering scientists; medical researchers, humanists, and social scientists.

I therefore am of the view that Institutional Research Culture is critical to research capacity building and research excellence. I therefore want to spend a few minutes looking at the characteristics of research culture. To be effective, institutional research culture has grown and sustained not only at the institutional level, but also at the faculty, school and departmental levels of any university.

What is Research Culture?

In the process of researching on institutional research culture I identified several characteristics. Many of these overlap in some way. I want to deal with some of these characteristics; some in a little more detail while others simply cursorily. In the process what we should be asking ourselves is the extent to which an institution, like the University of the Free State, and its faculties, individually and severally, is growing and or sustaining this culture.

Institutional Research Strategy: As a plan of action or guide for a course of action, the institutional research strategy must spell out research goals that a university wants to achieve. It must be a prescription of what the university needs to be done with respect to research. As a strategy it is neither an independent activity nor an end in itself, but a component part and operationalization of the university policy or mission. ( Related to this is the Establishment of Institutional research policies)

Includes and makes public the targets, e.g. achieve so many rated scientists and make sure that every year we have so many SAPSE publications. That way people keep an eye on research agendas of the university and nation.

The UFS is obviously on its way, having launched its own Research strategy (A Strategic framework for the development of research at the University of the Free Sate. August 2003). Note that this strategy refers specifically to the “Culture of research” Fig 1

A set of administrative practices to support and encourage research. Patricia Clements (English Department, University of Alberta, Edmonton) in her presentation Growing a research culture argues that that research activity and output within the her Faculty (Arts) were very low and, in spite of the numbers of staff, with no Associate Dean for Research in the Faculty as though they had accepted that research belonged to Medicine and Science and Engineering, and teaching, separated from inquiry, belonged to the Arts. With the change in the thinking about research and development of research culture, it became clear that there was a major role for research support in a faculty her size (now about 360 full time continuing academic staff). The faculty developed a support system for research and began to address the SSHRC issues.

Reduce the bureaucracy system and micromanagement of research! This however, also implies that there is capacity and policies and procedure to manage and guide research processes

Establishment of Intellectual Property regulations and assistance

Research ethics policy and safeguarding by research administration

Focused, applied and suitable nature of the delivery mode (an institution open to new methodologies for conducting research

Programmes suited both full and part-time study particularly at graduate level (Mainly at Faculty/school and department level, and depending on what’s manageable)

Hiring senior academics to engage in, teach on and supervise postgraduate students to facilitate exchange of and transfer ideas and most importantly mentorship especially in view of declining numbers of researchers in particular fields

Quality instruction and facilitation in learning about research processes

A high retention rate of students maintained by the supportive and challenging learning environment and the use of online facilities to support collaboration and in-class learning

Availability of research grants: and awareness of sourcing funds from external sources like the National Research Foundation; Water Research Commission; Medical Research Council, private philanthropies and others outside the country. For example an institution should be able to assess how much of the slice the available funds (NRF etc) its able acquire and possibly top slice from institutional budget.

Adequacy of the financial reward system to encourage university staff members to do research (General Celebration of achievement for research excellence and achievement. This ranges form Annual reports mention; celebratory dinner. At Alberta researchers were given lapels. I don’t know of any academic who do not feel a sense of achievement to get into print or recognised. Access to research facilities within and outside the institution

Provision of infrastructure to support university-based research (e.g. equipment, admin support, etc.) – but also awareness of publicly funded and available research facilities and equipment!

Internet connectivity and changes in the bandwidth of the internet to download articles

Subscription to related bodies by the library so that researcher can download articles

Facilities and resources to attend international conferences to keep one updated

Number of visiting professors/speakers targeting senior scholars and invite them to lunch to ask them to participate and to encourage their best graduate students to do so within the institution and across institutions

Research training seminars for research students including young academics

Participation of staff/students in delivering research papers to national and international conferences

Establishment of research groups to provide interaction frameworks to achieve critical mass of research-active staff

Facilitation for more research time: Targeting new scholars and giving them reduced teaching loads in their first year or two for the purpose of developing their research programs. For the purpose of helping new colleagues to see the shape of South African research support, personalizing it, and creating research community

Take research to the community and argue its necessity, and utility

And, finally celebrating excellence. We must recognize achievement - parties and public recognition for colleagues who achieve splendid things in their research.

In conclusion, I want to reemphasize that research culture has to be grown it does not simply exist in an institution. If it is grown it needs to be nourished, nurtured and sustained. An institution cannot simply leave on borrowed reputation and expect to remain research excellent. It is on this basis that instruments like the National Research Foundation rating system recognizes excellence within a given period of time and not necessarily for a life time! This it is believed encourages continued research excellence.
