Bridging Knowledge Cultures
A group of academics from the University of the Free State (UFS) and the North-West University (NWU) contributed to a chapter in the book Bridging Knowledge Cultures in Rural Health Education, which was recently launched during an online event.

The Directorate of Community Engagement at the University of the Free State (UFS) celebrated the publication of a chapter in the book, Bridging Knowledge Cultures. This transformative book was edited by Walter Lepore, Budd Hall, and Rajesh Tandon, Unesco co-chairs of the Unesco Chair in Community Based Research and Social Responsibility in Higher Education.

Chapter 10 of the book – ‘Bridging Knowledge Cultures in Rural Health Education’ – was contributed by a group of academics from the UFS and the North-West University (NWU). The UFS contributors included Dr Karen Venter, Head of Service-Learning in the Directorate of Community Engagement; Alfi Moolman, former coordinator in the same department; and Dr René Walter Botha, Coordinator for Community Based Education and Rural Health in the Faculty of Health Sciences. From the NWU, the contributors included Prof Lesley Wood, Extraordinary Professor in Community-Based Educational Research; Beatrix (Bibi) Bouwman, Director for Sustainability and Community Impact; and Prof Hendri Coetzee, Extraordinary Associate Professor in the North-West University’s COMPRES research unit.

Identify knowledge differences/gaps

According to Dr Venter, the study conducted in the Xhariep District was considered a unique context for an in-depth exploration of participants’ subjective experiences to identify knowledge differences/gaps, and recommendations to bridge them. She states, “The aim of the initiative was to improve health outcomes by establishing lifestyle groups to enable the sharing of health information among participants and thereby encourage sustainable, accountable lifestyle practices.” 

Three questions derived from the case study were discussed during the launch: Who has the right to create knowledge? Who decides if knowledge is valid? And who will have access to the knowledge?

Other case studies included in the book also explored the dynamics of equitable research partnerships, providing practical recommendations to overcome obstacles and forge effective collaboration between academia and diverse communities.

Embrace the richness of diverse perspectives

Dr Venter believes that the launch event inspired the next generation of researchers and professionals to embrace the richness of diverse perspectives and knowledge cultures.

To access the rest of the case studies, including those from Indonesia, Malaysia, and India, you can download the book here. Access the discussion on YouTube here.

Parallel to the book, a guide was launched: Bridging Knowledge Cultures: A Guide for Community Practitioners and Community Organisations. You can access a copy here.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
