Prof Angelique van Niekerk
The Top Management of the UFS was represented by Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, who welcomed the guests in Afrikaans. With him is Prof Angelique van Niekerk, who delivered her inaugural lecture; Dr Francois Smith, Head of the Department of Afrikaans and Dutch, German and French; and Prof Marlize Rabe, acting Dean of The Humanities.

In her inaugural lecture on 5 August 2025, Prof Angelique van Niekerk emphasised that linguistic choices in persuasive communication, specifically advertising communication, carry ideological implications. This is referred to as ‘linguistic capital’, which includes all the language instruments available to a competent language practitioner and/or copywriter.

The inaugural lecture, titled ’n Kulturele en psigolinguistiese perspektief op hoe 'n wêreldbeskouing beïnvloed word aan die hand van advertensiekommunikasie: 1995-2025 (A cultural and psycholinguistic perspective on how a worldview is influenced based on advertising communication: 1995-2025), offered an overview of some of her published research concerning the use of different linguistic instruments within the disciplines, such as syntax, sociolinguistics, morphology, semantics, pragmatics, etc.

Prof Van Niekerk, a lecturer in the Department of Afrikaans and Dutch, German and French at the University of the Free State (UFS), also elaborated on aspects such as nostalgia, controversy, intertextuality, identity, etc., from her research within applied linguistics, based on Afrikaans and English print advertisements.

The lecture concluded with examples from Afrikaans magazines and archives of the Loerie and Pendoring advertisements from 2020 onwards. These examples illustrated the importance of cultural congruence and intellectual challenge (play) in an effective (good) advertisement. 

“Recent examples (data) emphasise the importance of social issues as a point of reference; that with which the speaker (marketer) and audience (target market) identify – their good cause,” said Prof Van Niekerk. She referred to significant patterns from recent South African print advertising, stating that South African advertisements involve inclusivity, interactivity through the use of web addresses, QR codes, etc., acknowledgement of the market’s heritage/roots, cultural norms, etc., social consciousness, and a world without pretentiousness.

 

Prestigious attendees

In attendance was Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, who welcomed the attendees in Afrikaans. He described the event not only as a ceremonial right, but also as the celebration of a milestone, the sharing of knowledge, a goal, and setting the course for the future. “This (the inaugural lecture) is a joyous occasion, especially because it coincides with the official centenary of Afrikaans.” 

Prof Marlize Rabe, acting Dean of The Humanities and Vice-Dean: Teaching and Learning, introduced the star of the evening and highlighted some of Prof Van Niekerk's academic achievements, including a PhD in Afrikaans and Dutch and a master’s degree in Communication Sciences (cum laude), as well as a C rating from the National Research Foundation, underlining her contribution to academic research.

The final word of the evening belonged to Head of Department, Dr Francois Smith. “It is significant how you have proved how applied linguistics can get a grip on who and what we are and how we shape our world through language. Science allows us to take a step back and contemplate how language gives us the leverage to take hold of our world. This lecture underscores that our work is of value and has something to offer the world, because language can widen borders and gives us a way to look at the future.”

 


 

Vakmanskap van advertensiewese in intreerede bespreek

 

Prof Angelique van Niekerk, dosent in die Departement Afrikaans en Nederlands, Duits en Frans, het gedurende haar intreerede op 5 Augustus 2025 beklemtoon dat taalpraktyk, oftewel taalkeuse, in oorredende en spesifiek advertensiekommunikasie ideologiese implikasie inhou. Daar word hierna verwys as ‘linguistiese kapitaal’ en sluit in al die taalverwante instrumente in die hand van ʼn vaardige taalpraktisyn (kopieskrywer). 

Prof Van Niekerk het in haar intreerede, getitel ’n Kulturele en psigolinguistiese perspektief op hoe 'n wêreldbeskouing beïnvloed word aan die hand van advertensiekommunikasie: 1995-2025, eerstens ’n oorsig gebied van die navorsing wat sy reeds gedoen het oor die funksionele aanwending van die verskillende taalinstrumente binne die teoretiese dissiplines soos sintaksis, sosiolinguistiek, morfologie, semantiek, pragmatiek, ens.

Daarna het sy ’n oorsig gebied uit die toegepaste linguistiek (in Afrikaans en Engels) op grond van Suid-Afrikaanse advertensiekommunikasie. Die gebruik van aspekte soos nostalgie, kontroversie, intertekstualiteit, identiteit, ens. in die advertensiewese is juis om hierdie rede op data van 1995-2025 geskoei. Prof Van Niekerk het haar intreerede afgesluit met voorlopige insigte oor die aard van gedrukte advertensiekommunikasie uit datastelle sedert veral 2020 (Afrikaanse tydskrifte, advertensies uit die Pendoring- en Loerie-argief).

Die belangrikheid van kulturele kongruensie en intellektuele uitdaging (spel) in ʼn goeie/ doeltreffende advertensie – soos ook aangedui deur Gevorgyana en Manucharovab (2015) – is ook uitgelig. Onlangse advertensies (datastelle) blyk die belangrikheid te toon van sosiale kwessies as verwysingspunt; dit waarmee die spreker en ontvanger identifiseer (jou good cause). 

Die patroonmatigheid en opvallendhede uit meer onlangse Suid-Afrikaanse advertensies is uitgelig. Plaaslike advertensies behels multi-identiteite en ʼn (ras)-inklusiewe samelewing waarin tale saam gebruik en afgewissel word binne een teks/konteks; verhoogde interaktiwiteit deur webadresse, QR-kodes, ens.; erkenning van die teikenmark se herkoms, sosiale bewustheid (bv. genderregte en omgewingsbewaring) en ’n wêreld gestroop van valse skyn.

 

Vooraanstaande gaste

Prof Vasu Reddy, Adjunk-Visekanselier: Navorsing en Internasionalisering, het die gehoor in Afrikaans verwelkom. Hy het die geleentheid nie bloot as ʼn seremoniële reg beskryf nie, maar ook as die viering van ’n mylpaal, die deel van kennis, ʼn doelwit en as padkaart vir die toekoms. “Dit (die intreerede) is ’n vreugdevolle gebeurtenis, veral omdat dit saamval met die amptelike eeufeesviering van Afrikaans.”

Prof Marlize Rabe, waarnemende Dekaan van die Fakulteit Geesteswetenskappe en Visedekaan: Onderrig en Leer, het die ster van die aand aan die gehoor bekendgestel en sommige van haar akademiese prestasies uitgelig. Dit sluit in ʼn PhD in Afrikaans en Nederlands en ’n meestersgraad (cum laude) in Kommunikasiewetenskap, sowel as ‘n C-gradering van die Nasionale Navorsingstigting wat prof Van Niekerk se bydrae tot akademiese navorsing staaf.

Die laaste woord van die aand het aan die Departementshoof, dr Francois Smith, behoort. “Dit is besonders hoe jy gewys het hoe toegepaste linguistiek ons ’n greep kan gee op wie en wat ons is en ons wêrelde skep deur taal, hoe ons verlei en verlok word. Wetenskap laat ons terugtree en sien hoe taal gebruik word en ons ’n vashouplek gee. Dis ’n bevestiging dat ons wetenskap en loopbane iets bied aan die wêreld waarin ons is. Taal is ’n manier om ons wêreld te verbreed, grense oop te maak en ’n manier te gee om na die toekoms te kyk.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
