Pictured are, from the left: Dr Bennie Botha, Dr Lindie von Maltitz, Dr Leon Kruger, Dr Anathi Makamane, Dr Megan Welman Purchase, and Dr Marike Stander.

Today, after years of hard work, a group of PhD graduates in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) stepped onto the stage in the Callie Human Centre with a sense of accomplishment and excitement to receive their doctoral degrees. The graduates covered an array of topics in their studies – from the use of virtual reality in health-care education to the well-being of sheep. 

Avoiding cybersickness

Dr Bennie Botha, Lecturer in the Department of Computer Science and Informatics, created a framework for use in immersive virtual clinical simulations by virtual reality users (students), software developers, researchers, and educators. According to him, this can help to avoid cybersickness – much the same as motion sickness – a condition that can occur when an individual's perception of motion conflicts with their visual senses.

“The result is a more inclusive immersive virtual reality experience for students who would otherwise not be able to engage with this technology and reap the benefits it can bring to their education,” says Dr Botha, who wants to establish a global footprint and advance the use of all types of virtual reality in an African context.

He submitted his thesis: A framework to prevent or minimise cybersickness during immersive virtual clinical simulation.

Agricultural extensionists of the future

Dr Lindie von Maltitz, Lecturer in the Department of Agricultural Economics, conducted two studies in her research. The first was to determine the crucial skills and competencies that agricultural extensionists need in their modern-day workplace. The second focused on the available undergraduate curricula offered in South Africa, which fail to address these critical skills and competencies. She found a list of skills and professional competencies that are not sufficiently covered in the available curricula, and some are lacking entirely.

In the last chapter of her thesis, Skills and competencies of agricultural extension professionals in South Africa: implications for higher education curricula, Dr Von Maltitz provides recommendations on what to include in curricula at higher education institutions that will equip the agricultural extensionists of the future to excel in their profession and contribute to agricultural development. “I am excited to contribute more to curriculum development, especially in the field of agriculture in general. Farming with my husband for the past 20 years has allowed me to obtain first-hand experience in farming and agri-business. I have walked the road, and I am still walking it. I teach by bringing theory into context with real-life situations that I have personally experienced,” she states.

The well-being of sheep

Society often questions how we treat the animals we eat. Dr Leon Kruger, Lecturer in the Department of Animal Science, delves into this question through his research, titled: The effect of temperament and stress on production and immune response in sheep. His study explores, among others, the impact of short-term stress on production performance in sheep, the effect of stress on immune response post-vaccination, and the relationship between a sheep's temperament and stress.

“The focus is not just on doing what's perceived as best for the animals, but on applying practices that limit stress. We so often hear of marketing slogans such as grass-fed or grain-fed or Karoo lamb. Just imagine how the consumer would appreciate a slogan such as stress-free reared. It is not that far-fetched,” he believes.

Dr Kruger’s future research plans include investigating stressor effects associated with livestock auctions, examining the entire process from loading on the farm to unloading on the new farm. “I also want to compile a species vocabulary, analysing specific sounds that animals make in different situations. I want to describe the sound of an animal and link it to a situation, for example, the sound a ewe makes shortly after she lambs,” he says.

Adapting to climate change

Dr Anathi Makamane, Junior Lecturer in the Department of Sustainable Food Systems and Development, says the realisation that her research findings have spurred a tangible project aimed at increasing the capabilities of extension workers is immensely fulfilling. “Being part of a community dedicated to sustainable agriculture and witnessing the transformative impact of research outputs underscores the profound satisfaction derived from this journey,” she states.

Her thesis, Capacity of extension and advisory services in supporting farmers to adapt to climate change in the Eastern Cape, South Africa, sheds light on the critical role that extension workers play in assisting farmers with climate change adaptation. “My research outputs have translated into a practical project that aims to enhance the capacity of extension workers, ensuring that they possess the requisite skills to support farmers effectively,” explains Dr Makamane.

“Looking forward, my future goals involve the continued pursuit of research that directly contributes to the betterment of agricultural practices. Beyond this, I aim to engage in broader conversations on sustainable agriculture, collaborating with stakeholders to advocate for evidence-based policies that can benefit farmers nationwide,” she adds.

Managing potential environmental risks

With her PhD, Dr Megan Welman Purchase, Scientific Officer in the Department of Geology, explored the stability of iron-cyanide minerals found in the waste material of gold mines, commonly known as gold mine dumps or tailings facilities. The title of her thesis is: An investigation of the iron-cyanide mineralisation in gold mine dumps.

She says the implications of her work are of great significance for society. “Understanding the stability of iron-cyanide minerals helps in assessing and managing potential environmental risks associated with gold mine dumps. Moreover, the revelation that natural microbes can play a role in remediating cyanide contamination suggests a more sustainable and eco-friendly approach to addressing environmental concerns related to mining activities. This has the potential to positively impact both the environment and communities near mining sites,” Dr Welman Purchase explains. 

The article has been cited by international authors at least three times since its publication, demonstrating its value to a global audience.

In future steps, Dr Welman Purchase would like to delve deeper into and understand these gold mine tailings facilities. “Additionally, I plan to investigate the specific conditions under which these natural remediation mechanisms are most effective, paving the way for practical and scalable applications in mining and environmental management,” she states, excited to be involved in science that can make a difference.

Improving soil erosion conservation efforts

With her thesis, Dr Marike Stander, Lecturer in the Department of Geography, delved into the intricacies of soil erosion with her research. Concentrating on a catchment in the Eastern Free State renowned for erodible soils, her analysis of sediments unravelled their origins.

Highlighting the far-reaching consequences, Dr Stander says that “soil erosion has detrimental effects on agricultural productivity by degrading arable land quality, but also that sedimentation in water bodies diminishes reservoir storage capacity with a myriad of adverse effects on aquatic environments”. She adds that a profound understanding of soil erosion processes, coupled with identifying and quantifying sediment sources, can pinpoint conservation efforts. “For agricultural land, it means sustaining productivity and food security, and for water resources, it holds value in planning reservoir placement, optimising water storage and ensuring healthy aquatic environments,” she explains.

In line with global initiatives, she adds, “Healthy soils play a pivotal role in achieving many of the United Nations’ sustainable development goals (SDG), since it links to safeguarding terrestrial ecosystems, reversing land degradation, and promoting sustainable agriculture, to name but a few.”

“It is rewarding to contribute to the often-overlooked global environmental issue of soil erosion. The potential to make even a slight impact on the environment and society is meaningful and fulfilling,” she says.

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.
