Dr Dionne van Reenen received her PhD during the December Graduation Ceremonies at the UFS

Very seldom in modern history do we try to critically think about how our bodies and even more those of women are presented in modern popular culture. Through her PhD research project, Dionne van Reenen attempts to critically analyse ideological formations of the body in performance and its discursive distribution in the consumption of contemporary popular media, adding to existing literature and research on the topic.

Her dissertation is titled Performing the Erotic: (Re)presenting the Body in Popular Culture.

Van Reenen, a senior researcher at the Unit for Institutional Change and Social Justice at the University of the Free State (UFS), received her PhD qualification specialising in English on Wednesday 11 December 2019 during the final ceremony of the December Graduation.

Van Reenen has extensive experience in all areas of education. Her work at the Unit for Institutional Change and Social Justice is interdisciplinary, involving both everyday and institutional politics. She also holds a Master’s degree in Philosophy, which she obtained in 2013 from the UFS. In 2016, she chaired the UFS Language Policy Review Committee and established the Gender and Sexual Equity Office, which formulated the Sexual Harassment, Misconduct, and Violence Policy at the UFS. 

Changing of social constructs in media consumption

“My study focuses on performative framings of social constructs of gender, race, and class (along with size, age, and ability) in the ordering processes of society,” she says.  These performative framings in are in turn sustained by the (re)presentation of eroticised bodies in popular visual media in the 21st century. “These framings and orderings are critiqued as nothing new, but simply entertainment product that is trading in ideologies and stereotypes that have long been in sociocultural circulation, and they affect how people think, speak and act.” 

The study also shows that the dynamics of ‘virtuality’ and ‘visuality’ in the digital age are altering traditional demarcations of space, place, time, and community, and have paved the way for formations of global cultures that are, at the same time, informative, expedient, empowering, homogenising, prescriptive, and imperialising.

Whilst the #MeToo movement focused more on gender-based violence, gender inequality, and sexual violence, which are big social issues and do not exist in isolation, Van Reenen used her critical philosophical training to understand how, in the current era, the dominant discourse on representations of the body, particularly marginalised bodies, has been constructed at the popular level. 

With every PhD research dissertation the candidate’s main aim is to add new knowledge to a discipline. For Van Reenen, it is important that her research can contribute to a change in social and cultural constructs by re-imagining the (re)presentations of the body in popular media.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
