Dr Marié Herbst
Dr Marié Herbst received her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion. She hopes that the techniques and processes explored in her research will spark creativity in the way other designers approach their work.

“My research has unveiled the exquisite patterns generated by motion in nature and everyday objects – patterns that often evade our awareness as we encounter motion in a fleeting moment. Abstraction plays a pivotal role in unveiling these exquisite yet largely unnoticed patterns that surround us.”

This is the perspective of Dr Marié Herbst, who graduated at the University of the Free State (UFS) in December, receiving her PhD with specialisation in Design, titled The (S)Pace of Images: establishing a practice of the conscious abstraction of motion.

Abstraction, a key component of building design

Dr Herbst says that the abstract art movement has had a profound influence on how designers think about design. “Highly regarded architects such as Le Corbusier and Zaha Hadid identify their practice of creating abstract paintings as the driving force behind their ground-breaking building designs. Abstraction is therefore a key component of building design, although the process of how it is applied has historically not received adequate attention. My research explores the way abstraction enables designers to include design information that is only possible through the process of abstraction. One such aspect is motion. Through the process of tracing and superimposing still images extracted from films, I can integrate them into a single picture that shows the progression of time,” she explains.

She hopes that the techniques and processes explored in her research will ignite creativity in how other designers approach their work. “The concepts and techniques outlined in my research are intended to prompt other designers to reconsider the procedures they employ when crafting spaces,” she states.

In the future, Dr Herbst says, she would like to further explore the ideas sparked by her research, such as determining how design would be affected by recording movement in a three-dimensional environment. “New technologies such as LiDAR make the recording of three-dimensional information much simpler, and it will increasingly become a part of our everyday lives. This is a potentially useful information stream that could be applied to create novel designs,” she says.

‘Practice-based’ versus ‘design-led’ research

Prof Jonathan Noble, Head of the Department of Architecture, says this is the very first PhD from the new creative research programme in architecture that was launched in 2018, where the student has completed a ‘design-led’ enquiry. 

He explains that the new creative programme differentiates between ‘practice-based’ research, closely tied to real-world architecture, where candidates analyse and study their previous work, and ‘design-led’ research, which is led by an entirely new creative exploration that encourage speculation and experimentation. According to him, the latter leads to a creative enquiry, and this body of new work is analysed and written about.

Following Prof Noble, postgraduate research in architecture in South Africa has traditionally centred around architectural theory, cultural history, urban studies, and conservation. Creative research methods, however, have not been as prominent. The Department of Architecture is addressing this by introducing new postgraduate research modes supported by innovative research degrees, marking a departure from the traditional approach in South Africa.

“We believe the programme will have a lasting and significant effect upon our professional degrees, injecting professional creativity and new thinking into the life of the department, and serving as an opportunity to look deeply into design and pedagogic practices. Over time, the programme will strengthen ties with the profession and address the closed mentalities of the so-called ‘academic ivory tower’.”

“In addition to providing emerging young scholars with opportunities, the programme facilitates the documentation of the unique qualities of South African practice and makes an important contribution to future research publication and teaching pedagogy at the UFS and beyond,” he says.

Childhood obesity should be curbed early

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.

Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.

Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.

Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.

Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.

The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.

A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.

The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.

When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.

Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.

At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.

The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
