The group, moderated by NWU students, functions as a platform where members post, comment and engage in various languages, including indigenous ones.</p> <p>“Multilingualism in this group goes beyond translation,” says Ontiretse. “It plays a role in shaping identity, access to information and participation.”</p> <p>The research used sociolinguistic theories, specifically the language variation theory and social network theory, to investigate the relationship between language and online interaction. A netnographic approach allowed her to observe communication patterns and analyse content shared on the group.</p> <p>One participant noted, “When someone posts in Setswana, I feel more at home. But sometimes I skip posts I don’t understand.”</p> <p>The findings highlighted that language diversity boosts communication effectiveness and cultural exchange among members. However, the study also identified ongoing challenges such as the preference for English, unequal access to digital tools, and gaps in indigenous language comprehension.</p> <p>“Using many languages helps reach more people, but it also risks leaving some out,” says Ontiretse.</p> <p>She believes this research offers a lens into broader issues of language use in South Africa’s digital communities. “Social media reflect real tensions and opportunities in multilingual societies,” Ontiretse says. “Understanding how people navigate them helps shape more inclusive digital spaces.”</p> <p>The study contributes to ongoing discussions about preserving indigenous languages while recognising the limitations of current strategies in virtual environments.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" height="569" id="" src="/sites/news.nwu.ac.za/files/images/Ontiretse%20Motingwa.jpg" title="" width="379" /></p> <p>Ontiretse Motingwa’s study explores how language diversity affects interaction on the NWU Mahikeng Campus Updates Facebook Group.</p> </div> Mon, 21 Jul 2025 10:28:15 +0000 BELINDA BANTHAM 31013 at https://news.nwu.ac.za Smart mushroom biotechnology can enhance feedstuffs for broiler production https://news.nwu.ac.za/smart-mushroom-biotechnology-can-enhance-feedstuffs-broiler-production <span>Smart mushroom biotechnology can enhance feedstuffs for broiler production </span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Oscar">Oscar Mosiane</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Mon, 07/21/2025 - 12:24</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Feed costs are exceptionally high in the broiler chicken industry, prompting farmers and researchers alike to find ways to reduce the cost of feed without compromising bird health. Dr Makiwa Simeon Mthana, a North-West University (NWU) animal science graduate, has come up with a potential solution that uses mushroom biotechnology to enhance the nutritional utility of soyabean replacements.</p> <p>For his PhD research, Dr Mthana evaluated “smart strategies” such as the use of oyster mushroom spent substrate (OMSS) to enhance the nutritional utility of marula seed (kernel) cake (MSC) and mucuna seed meal (MSM) as soyabean replacements in broiler chicken production. OMSS is a waste by-product of mushroom production.</p> <p>He was supervised by Dr Doctor MN Mthiyane from the Animal Science subject group, who has published numerous research articles on MSC and MSM in internationally recognised, peer-reviewed scientific journals, and serves as the sub-editor of the Applied Sciences journal.</p> <p>Owing to the birds’ high meat yields over short production cycles, broiler chicken production is seen as strategically important as a protein-rich food to nourish the rapidly growing human population in South Africa and globally in a relatively environmentally friendlier way.</p> <p><strong>High feed costs are a stumbling block</strong></p> <p>Broiler meat is the most consumed animal-derived protein source nationally and around the world. However, broiler chicken feeds are expensive, representing about 65% to 75% of the total variable costs of producing the birds, mainly due to dietary usage of the largely imported soyabean meal as a protein source. This problem has accentuated the need to explore economically sustainable alternative protein sources such as MSC and MSM to replace soyabean meal in broiler diets.</p> <p>While rich in proteins, energy and other nutrients, both MSC and MSM contain potentially toxic chemical substances called antinutritional factors. These include condensed tannins, 3,4-dihydroxy-L-phenylalanine (L-DOPA), mould-derived mycotoxins and a high fibre content. When consumed with the feed, these antinutritional factors can cause detrimental effects in broiler chickens, leading to poor nutrient digestibility, growth and meat quality in the birds.</p> <p>As a strategy to counter the deleterious effects of the antinutritional factors, Dr Mthana included OMSS in the diets of chickens. OMSS is rich in antioxidant bioactive compounds andbiodegradative enzymes, with formidable potential to break down toxic antinutritional factors and fibre.</p> <p>Dr Mthana investigated the effects of OMSS in a study involving 308 broiler chicks, which were randomly allocated to various diets, with and without OMSS. The study concluded that low levels of OMSS (1,25%) could limit the adverse effects of feeds containing MSC and MSM.</p> <p><strong>Best student poster in national competition</strong></p> <p>In 2024, Dr Mthana participated in a student poster competition organised by the Animal Feed Manufacturers Association and was named the overall winner of the Best Student Nutrition Poster Award.</p> <p>The South African Society for Animal Science also awarded Dr Mthana the bronze medal for the best PhD thesis, acknowledging its contribution to the advancement of animal science.</p> <p>On completing his doctoral studies at the NWU at the end of 2024, Dr Mthana relocated to the University of Mpumalanga. He is now a postdoctoral fellow under the mentorship of Prof Victor Mlambo.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Dr%20Makiwa%20Mthana-STORY(1).jpg" title="" /></p> <p>Dr Makiwa Simeon Mthana</p> <p><img alt="2" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Mucuna%20seed%20meal-STORY(1).png" title="" /></p> <p>Mucuna seed and Mucuna seed meal.</p> </div> Mon, 21 Jul 2025 10:24:51 +0000 BELINDA BANTHAM 31012 at https://news.nwu.ac.za Reimagining higher education through cross-faculty collaboration https://news.nwu.ac.za/reimagining-higher-education-through-cross-faculty-collaboration <span>Reimagining higher education through cross-faculty collaboration </span> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Wed, 07/16/2025 - 09:21</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Higher education, that sprawling landscape of lecture halls, research labs and late-night study sessions, is undergoing a quiet but profound transformation. The Covid-19 pandemic shattered the status quo, pushing universities to rethink the way they engage with students and each other.</p> <p>Now, a group of researchers from the North-West University (NWU) – Nombulelo Zenani, Nisa Ayob, Alexander Samuels and Martin Chanza – have taken a closer look at how universities can break down academic silos to improve student engagement and academic success. Their findings, published in the Management and Economics Research Journal, offer a fresh perspective on how to turn the ivory tower into a bustling marketplace of ideas.</p> <p>Their review, which draws on a wide range of studies from disciplines as diverse as health sciences, natural sciences, economics, and education, argues that collaboration across faculties is not just a buzzword but a practical necessity. "Interprofessional collaboration is more than just a nice-to-have," Nombulelo notes. "It’s essential for creating a cohesive learning environment where students can thrive."</p> <p>At the heart of this approach is the idea that students do not learn in isolation. Their academic success depends on the quality of the connections they make – with their peers, their instructors, and the broader academic community. The review identified four key themes that can help universities foster these connections: the use of technology in teaching, work-integrated learning, student-centric approaches, and reflective practices.</p> <p>Technology, for example, can bridge the gap between students and lecturers. Online collaboration platforms, digital discussion boards, and blended learning tools make it easier for students to engage with their coursework and each other, even when physical proximity is not possible. "Technology should not be seen as a substitute for in-person learning," Nisa explains, "but as a powerful tool that can enhance the learning experience when used effectively."</p> <p>Work-integrated learning, another pillar of the team’s findings, focuses on the practical side of education – giving students the skills they need to thrive in the workplace. This approach integrates real-world experiences into academic curricula, ensuring that graduates leave university not just with theoretical knowledge but also with the practical skills employers demand.</p> <p>Alexander points out that this approach is particularly relevant in fields like health sciences, where students must be prepared for the realities of clinical practice. "It’s not enough for students to know the theory," he says. "They must be able to apply it in high-stress, real-world situations."</p> <p>But effective teaching is not just about technology and real-world experience. It’s also about creating learning environments where students feel valued and motivated. The review highlights the importance of student-centric approaches, like flipped classrooms and active learning strategies, which put students in the driver’s seat of their education. These methods encourage critical thinking, collaboration, and self-directed learning – skills that are essential in today’s fast-paced, information-rich world.</p> <p>Finally, the team emphasises the value of reflective practices – encouraging both students and lecturers to regularly assess what works and what doesn’t in the learning process. "Reflection is a powerful tool for growth," Martin notes. "It helps educators fine-tune their teaching strategies and gives students the self-awareness they need to succeed."</p> <p>As the world of higher education continues to evolve, the findings of Nombulelo, Nisa, Alexander and Martin offer a roadmap for institutions looking to break down silos and build more collaborative, student-focused learning environments. By embracing technology, integrating real-world experiences, and fostering a culture of reflection, universities can prepare their students for the challenges of a rapidly changing world – and maybe even produce the next generation of great thinkers in the process.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Researchers-STORY.jpg" title="" /></p> <p>From left are Nombulelo Zenani, Nisa Ayob, Alexander Samuels and Martin Chanza.</p> </div> Wed, 16 Jul 2025 07:21:38 +0000 BELINDA BANTHAM 31001 at https://news.nwu.ac.za International expert launches tissue bioprinting laboratory at NWU https://news.nwu.ac.za/international-expert-launches-tissue-bioprinting-laboratory-nwu <span>International expert launches tissue bioprinting laboratory at NWU </span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Willie">Willie du Plessis</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Wed, 07/16/2025 - 09:16</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Tissue bioprinting and regenerative medicine are critical new frontiers in advancing human health. In partnership with a top Spanish researcher, the NWU has dramatically expanded its bioprinting research and innovation capabilities in its quest to find alternatives to animal testing and enhance personalised medicine.</p> <p>Prof Daniel Nieto, an international expert from the University of A Coruña in Spain, visited the North-West University (NWU) from 5 to 9 May to inaugurate the DNietolab-NWU Biofabrication Research Unit at the Centre of Excellence for Pharmaceutical Sciences on the Potchefstroom Campus.</p> <p>Prof Nieto, who coordinates the Advanced Biofab group at the Interdisciplinary Center for Chemistry and Biology (CICA) in Spain, facilitated the installation of a state-of-the-art 3D bioprinter at the NWU and conducted hands-on training sessions with local researchers and students.</p> <p>“This is a first for Africa and the first implementation in South Africa of customised light-based bioprinting technology for tissue engineering and regenerative medicine from HealthBiolux,” says Prof Lissinda du Plessis, who leads the project together with Prof Chrisna Gouws. They work with six postgraduate students.</p> <p>The bioprinter has been added to the 3D bioprinting laboratory, which will serve as a hub for research and innovation. There are plans for an annual workshop in A Coruña starting in February 2026 to further strengthen ties between the research teams.</p> <p>The partnership aims to boost international cooperation in the fields of biomanufacturing, 3D bioprinting and regenerative medicine, and pursue alternatives to animal testing.</p> <p>It also sets the stage for academic exchange, resource sharing and joint research initiatives between the two institutions.</p> <p>“While the NWU has strong foundations in basic scientific research, our work at CICA focuses on applied science,” says Prof Nieto. “This collaboration allows us to combine our strengths and offer students from both institutions a richer, more integrated research experience.”</p> <p>“This is a significant milestone for the NWU and for research in Africa,” says Prof Gouws. “We are building a global network that empowers students and researchers to address some of the most pressing challenges in biomedical science.”</p> <p><strong>NWU has the biggest cluster for 3D spheroid cell culture</strong></p> <p>The NWU already has significant strengths in the field of biomedical science. These include the largest CelVivo ClinoStar System cluster for 3D spheroid cell culture in the world.</p> <p>The ClinoStar system is based in Prof Gouws’ research group, which is acknowledged as one of the leading groups in Africa for advanced cell modelling research. The system</p> <p>promotes the growth, maintenance and functionality of large tissue, including spheroids and organoids.</p> <p>The 3D cultures and tissue that the research group creates through bioprinting can be used to facilitate drug development and toxicity, and are also relevant in the study of tissue and disease formation and progression to improve personalised medicine.</p> <p>“These 3D tissue models give us attractive alternatives to animal testing,” says Prof du Plessis. “By developing non-animal alternative models and new approaches that are relevant to the African context and with African genetics, we are addressing both the need for animal alternatives and genetic diversity in South African biomedical research.”</p> <p><strong>CICA research centre is known for its excellence</strong></p> <p>The CICA research centre, established in 2015, is recognised for its excellence in biomedicine, nanoscience and environmental health.

Star and celebrity have always been a staple for glittering marquees of Broadway to the neon-lit stages of the West End, however this has in recent decades become a contentious issue as celebrity as a concept has undergone tremendous change. When looking to fill seats in theatres the phenomenon of casting TV and film stars has become a defining feature, sparking debates as intense as a show-stopping ballad.</p> <p>The roots of this star-centric approach stretch back to the early 20th century, when impresarios like Andrea Charlot and Charles B. Cochran leveraged the fame of popular performers to fill theatres. Charlot, known for showcasing extraordinary British talent on a shoestring budget, famously collaborated with Noël Coward to stage intimate, actor-led productions. In contrast, Cochran’s lavish spectacles featured the celebrities of his day, often imported from film and radio – a strategy that earned him the moniker ‘the British Ziegfeld’.</p> <p>Dr Michelle Pretorius, a senior lecturer at the North-West University’s (NWU’s) School of Music and author of a recent study on the topic, explains that the distinction between ‘star’ and ‘celebrity’ is crucial to understanding this evolution. “Stars are performers known for their craft, whose reputations rest on their talent and ability to command the stage,” she says. “Celebrities, on the other hand, are public figures who have transcended their original medium, leveraging their fame across platforms. They are, in a sense, human brands – able to sell tickets as much by virtue of their name as by their talent.”</p> <p>Her study titled “The changing nature of celebrity in musical theatre: The development of star casting” was published in the journal Celebrity Studies and notes how this commercial power has become an increasingly attractive asset for producers navigating the high-risk economics of musical theatre.</p> <p>For example, stars like Ethel Merman, whose brassy voice and onstage magnetism made her a Broadway icon, or Mary Martin, who transformed from a little-known film actress into a household name with her roles in South Pacific and Peter Pan, exemplify this star power. In contrast, celebrities often bring pre-packaged fan bases, social media followings, and tabloid-ready personal lives – potent ingredients in a marketing cocktail designed to fill seats and drive ticket sales.</p> <p>But the path from stage to stardom is no longer the only route to fame. The late 20th and early 21st centuries saw a seismic shift as reality television emerged as a celebrity factory. Shows like The X Factor and America’s Got Talent catapulted ordinary people to global fame, often with little more than a knack for high drama and a few catchy choruses.</p> <p>Dr Pretorius notes that this shift has fundamentally altered the casting landscape, creating a “new breed of celebrity, groomed for instant mass appeal.”</p> <p>However, not all in the theatre community have embraced this trend. Traditionalists argue that the art form risks losing its integrity, becoming a mere vehicle for stardom rather than a showcase for true theatrical talent. They worry that the emphasis on celebrity over skill dilutes the craft, leading to productions where vocal finesse and stage presence take a back seat to brand appeal.</p> <p>Yet, the financial lure of celebrity casting remains compelling. As theatre struggles to recover from pandemic shutdowns and fierce competition from streaming platforms, the draw of a ready-made audience can be a lifeline. For every sceptical critic, there is a delighted producer counting the box office returns of a hit show bolstered by a marquee name.</p> <p>As the curtain rises on a new era of musical theatre, the debate over celebrity casting is unlikely to fade. Whether a temporary trend or a lasting evolution, the question remains: Can musical theatre balance the glitter of celebrity with the grit of true talent, or will it risk becoming a sideshow in the circus of modern celebrity culture? Only time will tell.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Michelle%20Pretorius-STORY.jpg" title="" /></p> <p>Dr Michelle Pretorius.</p> </div> Tue, 15 Jul 2025 10:43:33 +0000 BELINDA BANTHAM 30994 at https://news.nwu.ac.za The soil sleuths of the Highveld: Why local knowledge still matters https://news.nwu.ac.za/soil-sleuths-highveld-why-local-knowledge-still-matters <span>The soil sleuths of the Highveld: Why local knowledge still matters </span> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Tue, 07/15/2025 - 12:38</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Soil – humble, overlooked and often taken for granted – is one of the most vital resources on Earth. Yet, understanding its complex chemistry remains a scientific challenge, particularly in the vast, varied landscapes of South Africa.</p> <p>A recent study by Anru-Louis Kock, Prudence Dimakatso Ramphisa-Nghondzweni and George Van Zijl from the North-West University (NWU) has brought this challenge into sharp focus. Their work, published in the European Journal of Soil Science, explores the promise and pitfalls of using mid-infrared (MIR) spectroscopy to assess soil quality in the Western Highveld region – a cornerstone of the country’s agricultural economy.</p> <p>Spectroscopy, in essence, is the art of making invisible details visible. It measures how light interacts with matter, revealing the chemical composition of a sample without the need for messy, time-consuming lab work. In theory, this should be perfect for soil analysis – quick, cost-effective and eco-friendly. But as the authors of this study discovered, the reality is more complex.</p> <p>Soil spectroscopy has long been championed as a game-changer for precision agriculture – the practice of tailoring crop inputs to the exact needs of the soil. However, as Anru-Louis and his colleagues reveal, the one-size-fits-all approach to soil analysis favoured by global databases like the Open Soil Spectral Library (OSSL) often falls short when applied to local contexts. "Global models, while impressive in scope, struggle to capture the unique characteristics of South African soils," Anru-Louis explains. "Our study clearly shows that if you want accurate predictions for key soil properties like pH, calcium and magnesium, you need locally calibrated models."</p> <p>The team’s study used 979 soil samples from the Western Highveld to create locally calibrated MIR models. These models significantly outperformed their global counterparts, achieving prediction accuracy with R² values exceeding 0,76 for critical soil properties like pH, calcium and magnesium – a feat the OSSL models could not match. The problem, as the researchers point out, is that global databases simply lack the depth of local knowledge needed to accurately interpret the soil spectra of this diverse region.</p> <p>The Western Highveld, known for its nutrient-poor, highly variable soils, presents a unique challenge for soil scientists. It is a region where farmers grow maize, wheat and sunflowers in conditions that range from dry, sandy plains to heavier clay soils, each with its own mineral profile. This variability can significantly affect crop yields and nutrient uptake, making precise soil analysis essential for sustainable farming.</p> <p>"The OSSL models consistently underpredicted key soil properties," notes Dimakatso. "They lacked the nuanced understanding of our local soils, which meant they couldn’t provide the reliability needed for precision agriculture." This finding, while disappointing</p> <p>for proponents of global data-driven agriculture, reinforces a critical point – that local context still matters, even in a world increasingly dominated by big data.</p> <p>The study also highlights the importance of investing in local soil libraries. "Without locally calibrated models," George adds, "farmers could be making decisions based on inaccurate data, potentially leading to poor crop performance and financial losses. Our work is a step towards building a comprehensive South African soil spectral library that can support smarter, more sustainable farming practices."</p> <p>As global agriculture grapples with the twin challenges of climate change and population growth, local data will remain essential for making accurate, region-specific decisions. The work of Anru-Louis, Dimakatso and George serves as a timely reminder that even in the age of artificial intelligence and machine learning, sometimes the best insights come from the ground up.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/soil-researchers-STORY.jpg" title="" /></p> <p>From left are Anru-Louis Kock, Prudence Dimakatso Ramphisa-Nghondzweni and George Van Zijl.</p> </div> Tue, 15 Jul 2025 10:38:14 +0000 BELINDA BANTHAM 30993 at https://news.nwu.ac.za Two tracks, one path, as NWU alumna navigates cybersecurity and songwriting https://news.nwu.ac.za/two-tracks-one-path-nwu-alumna-navigates-cybersecurity-and-songwriting <span>Two tracks, one path, as NWU alumna navigates cybersecurity and songwriting</span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Mafumane">Mafumane Tlhapi</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Fri, 07/11/2025 - 08:08</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Information Technology Security and music composition are not as far removed from each other as they might seem.

She documents and reports security incidents in weekly meetings to facilitate threat identification and effective response. She leads the development of security policies and procedures to strengthen governance practices throughout the organization.</p> <p>After hours, she performs at events, works as a voice-over artist for advertising campaigns, or collaborates with international producers. In 2024, she contributed to Chicken Licken’s “Snack Rappin” campaign, voicing one of its promotional wraps.</p> <p>She currently has a released single with Afro-house international DJ, Zulu Mageba and a project to be released where she is featured by the South African famous music duo, Black Motion.</p> <p>“Working in the studio requires the same level of preparation and awareness as a boardroom,” Phiri says. “You need to read the room, understand the risks and know your role.” She also mentors young people with an interest in either the arts or cybersecurity, and advises aspiring entertainers not to abandon their academic goals.</p> <p>“Never leave your studies for the microphone,” she says. “The entertainment industry has highs and lows; education offers stability.” That perspective, she notes, was shaped during her time at the NWU.</p> <p>“As a student, I learnt how to carry myself in meetings and on stage. That balance is what keeps me moving forward.”</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Bonolo%20Phiri%201.jpg" title="" /></p> <p> NWU alumna Bonolo Phiri balances risk assessments by day and rhythms by night.</p> </div> Fri, 11 Jul 2025 06:08:38 +0000 BELINDA BANTHAM 30988 at https://news.nwu.ac.za Prof Ankit Katrodia champions NWU’s global footprint in Europe https://news.nwu.ac.za/prof-ankit-katrodia-champions-nwus-global-footprint-europe <span>Prof Ankit Katrodia champions NWU’s global footprint in Europe </span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Zeno">Zenoyise John</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Fri, 07/11/2025 - 08:06</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Prof Ankit Katrodia, associate professor in the WorkWell research unit at the School of Management Sciences of the North-West University (NWU), recently undertook an enriching academic tour across Poland and Romania.</p> <p>His participation in this European engagement was made possible through some of the external funding from the Bucharest Academy of Economic Studies – Bucharest in Romania and reflects the growing commitment of the NWU to international collaboration and academic exchange.</p> <p>During his three-week journey in May 2025, Prof Katrodia took part in international conferences, delivered guest lectures, and served as a visiting professor at leading academic institutions. His presence not only strengthened the academic visibility of the NWU abroad but also opened doors for lasting partnerships and joint research opportunities.</p> <p>From 12 to 16 May, Prof Katrodia attended the 2nd International Conference on Social Contexts of Science at the Faculty of Management, Wrocław University of Science and Technology in Poland. The event ran concurrently with International Staff Training Week and brought together scholars from across Europe. Reflecting on his time there, Prof Katrodia shared: “It was inspiring to exchange perspectives with global scholars and contribute to conversations around the evolving social impact of science. These platforms not only enhance our research but also open doors for future collaborations that can benefit both students and staff at the NWU.”</p> <p>Following his engagements in Poland, Prof Katrodia travelled to Cluj-Napoca, Romania, from 19 to 24 May. At the Babeș-Bolyai University – one of Romania’s premier academic institutions – he lectured students and took part in dynamic academic exchanges. He also presented his research at an international conference hosted by the Faculty of Business.</p> <p>“The students were highly engaged, and the discussions were rich and reflective,” he noted. “It is energising to witness the passion for learning across different academic cultures. The level of dialogue in Cluj reaffirmed the universal value of critical thinking and innovation.”</p> <p>The final leg of his tour took him to the Bucharest University of Economic Studies from 26 to 31 May, where he served as a visiting professor. During this period, Prof Katrodia engaged with faculty members, participated in curriculum exchange sessions, and explored opportunities for collaborative research between the NWU and Romanian institutions. “This visit was not only a platform for teaching but also provided a mutual learning opportunity. The commitment to academic excellence in Romania echoes the values we uphold at the NWU,” he said.</p> <p>Prof Katrodia added that his European academic journey highlighted the dedication of the NWU to global engagement, research excellence and the pursuit of meaningful international partnerships. He said his contributions abroad continue to reinforce the position of the NWU as a globally connected institution with a vision for innovation, collaboration and internationalisation.</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Prof%20Katrodia-STORY.png" title="" /></p> <p>Prof Ankit Katrodia recently undertook an enriching academic tour across Poland and Romania</p> </div> Fri, 11 Jul 2025 06:06:04 +0000 BELINDA BANTHAM 30987 at https://news.nwu.ac.za Study questions the political inclusion of Malawi’s disabled on airwaves https://news.nwu.ac.za/study-questions-political-inclusion-malawis-disabled-airwaves <span>Study questions the political inclusion of Malawi’s disabled on airwaves</span> <div class="field field--name-field-writer field--type-list-string field--label-hidden field--item">by <a href="https://news.nwu.ac.za/news-team#Mafumane">Mafumane Tlhapi</a></div> <span><span lang="" about="/user/32504" typeof="schema:Person" property="schema:name" datatype="">BELINDA BANTHAM</span></span> <span>Mon, 07/07/2025 - 09:16</span> <div class="field field--name-body field--type-text-with-summary field--label-hidden field--item"><p>Persons with disabilities in Malawi may be tuning in to community radio, but their political voices are not adequately covered.</p> <p>A recent study led by Dr Muyanga Ziba has raised questions about the role of community radio in promoting the political participation of persons with disabilities in Malawi. Using Mzimba Community Radio Station as a case study, the research found that while general programming for people with disabilities exists, there is no dedicated content focused on political engagement.</p> <p>“There is a noticeable gap in programming that targets political inclusion,” said Dr Ziba. “The absence of dedicated political content for persons with disabilities means they are not fully represented in public discourse.”</p> <p>The research focused on four constituencies, namely Mzuzu, Mzimba North, Mzimba Solola and Mzimba East, using listening clubs, focus group discussions and in-depth interviews. The study drew from theoretical frameworks, including disability theory, framing theory, participatory theory and muted group theory.</p> <p>Participants reported facing systemic barriers to political participation, including abuse, social exclusion and a breakdown of traditional support systems. Some said even close friends and relatives discouraged their involvement in politics.</p> <p>“Many of us are seen as incapable,” said one participant from Mzimba Solola. “Even if you speak up, people laugh at or ignore you.”</p> <p>The study also highlighted how stereotypes are perpetuated through media messaging and the lack of tailored political content. Respondents called for media reform that moves beyond generalised information to targeted, inclusive content.</p> <p>To address these issues, Dr Ziba recommends that Mzimba Community Radio Station adopt journalism practices rooted in ubuntu and Africanisation. “Western media models do not always fit our context,” he said. “We need approaches that are grounded in our values and communities.”</p> <p>The study also advocates for journalism of attachment, urging reporters to connect with communities rather than report from a distance. A new participatory communication framework has been proposed to ensure that voices from marginalised groups in villages are not only heard but also represented.</p> <p>Peace journalism and ubuntu journalism are further recommended to create an environment conducive to political participation by persons with disabilities.</p> <p>“This is not just about airtime,” Dr Ziba said. “It is about access to platforms that shape democracy.”</p> <p><img alt="1" class="img-responsive" data-entity-type="" data-entity-uuid="" id="" src="/sites/news.nwu.ac.za/files/images/Dr%20Ziba%20(Middle)%20with%20his%20supervisors%20Dr%20Quantro%20Mgogo%20(Left)%20and%20Dr%20Tshepang%20Molale%20(Right).jpg" title="" /></p> <p>Dr Ziba (Middle) with his supervisors Dr Quantro Mgogo (Left) and Dr Tshepang Molale (Right)</p> </div> Mon, 07 Jul 2025 07:16:11 +0000 BELINDA BANTHAM 30972 at https://news.nwu.ac.za
