The intersectionality between politics, feminism, and social justice was unpacked extensively in the Student Affairs Women’s Month Webinar that took place on 25 August 2020. This was the second in a series initiated by the Qwaqwa Campus Student Affairs. Director of Student Affairs, Nicole Morris, said the webinars were initiated to encourage difficult conversations around womanhood in South Africa.

UFS Vice-Rector Institutional Change, Student Affairs, and Engaged Scholarship, Prof Puleng LenkaBula, and renowned businesswoman and media mogul, Carol Bouwer, were featured in the second instalment. Together they unpacked the dynamics of being a woman in modern-day South Africa in the face of the scourge of violence against women and children, as well as the transformation and greater representation of women in both positions and institutions of power.

 

Challenge the systems

Setting the tone, Prof LenkaBula said society as a collective needed to come together to challenge systems that oppress, mute, silence, and make it impossible for women to become dignified and contribute fully to the society we live in.

 “If we are to promote social justice, feminism, ethics, and gendered analysis, we have to ensure that we constantly challenge, rethink, and think again around issues that we feel are withholding women from being fully themselves.”

 Bouwer and Prof LenkaBula said the nation is constantly diverted to other issues that are shifting the focus from amplifying voices for the protection of women and children, hence no real change has taken place.

 “As someone who began working during the birth of our freedom in 1994, I think back to the elation that we felt at the creation of the constitution. There was so much jubilation about it, but we exported that excitement to the world and talked about what we had attained without practising it here.”

 “We continue to create systems and amazing documents as a nation, yet we do not implement the very things that will lead to a point where discussions such as these do not need to take place,” Bouwer said.

 Bouwer said the COVID-19 pandemic showed that South Africa had the necessary resources to prioritise gender-based violence, but those in power chose not to.

 “As we speak today, gender-based violence has become a national crisis. We talk about the intersectionality between politics, feminism, and social justice against the confluence of the opposite happening. With what happened when the COVID-19 pandemic was declared a national disaster, we’ve realised that we do have the wherewithal to mobilise for action in this nation, and it is the one thing we have not seen our leaders do,” she said.

 

Part-time feminism will not help

Prof LenkaBula said rethinking feminism was needed to move away from definitions of anti-manhood in order to promote feminist ideals that would benefit the nation as a whole.

 “As a feminist, I want to promote the idea that feminists are not promoting the defamation or marginalisation of men or stripping them of their dignity. We are saying that as men and women, no matter our gender or sexuality, we can work together to ensure that we all live with dignity, we all are equal, and we all express our talents, and are able to utilise opportunities that are available to us in fair ways.”

 Alluding to this, Bouwer said she hoped to see part-time feminism done away with in the rebuilding of society after the pandemic. “Coming out of this pandemic, may our feminism be transformed by everything that is currently happening. There is a huge injection of pathos happening right now and I hope that it is not a fad like everything else that has happened in South Africa, but that it becomes something that we really embody as we go back to whatever normal is going to look like,” she said.

 Qwaqwa Campus SRC Secretary General, Nelisiwe Masango, said the Division of Student Affairs planned the Women’s Month Webinars to discuss topics on issues that affect women directly.

 “These programmes are quite insightful and uplifting. They especially encourage young women to see that the revolution is there, it is real, and it is practical. It gives meaning to continue advocating for better and safe spaces for women. Many times, spaces of contestation are male dominated and therefore women have to be empowered to contest these spaces. These engagements must be ongoing or continuous so that we all understand the issues we are affected by and advocate for a better society.”

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.

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.
