Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

Prof Helene Strauss delves into the emotion and politics of contemporary South African protest cultures
2014-12-22

Prof Helene Strauss from the University of the Free State’s (UFS) Department of English currently researches the relationship between emotion and politics in contemporary South African public and protest cultures.

The research foregrounds the complex set of concerns opened up by a study of intimacy, read as not simply a sign for emotional and sexual closeness, but more broadly as a complexly mediated site from which to observe the embodied, affective coordinates of various forms of control and contestation. Through the analysis of a range of cultural texts that, for instance, recompose moments of spectacular social upheaval through the lenses of everyday, embodied experience, this research considers what aesthetic responsibility might mean in both post-transitional South Africa and elsewhere.

One aspect of this research charts a gradual shift in South Africa from what is frequently referred to as the ‘liberation euphoria’ of the mid- to late 1990s – and the optimistic fantasies of a future South Africa that characterised dominant public discourse in the period immediately following the political transition – toward an emotional culture in which expressions of anger, disillusionment and disappointment seem to have become relatively widespread.

Prof Strauss asks, for instance, how these public feelings have been managed in the aftermath of events such as the Marikana massacre, and suggests that the affective and temporal dimensions of current attempts at containing perceived threats to financial and political stability on the part of South Africa’s business and political elite are key to understanding increasingly violent and repressive securitisation strategies.

Earlier this year, Prof Strauss presented papers on aspects of this research at two international conferences: (i) the Association for Cultural Studies conference in Tampere, Finland, where she was invited to be part of a ‘Spotlight Panel’ on the topic of African Cultural Studies, (ii) and at a conference at McMaster University in Hamilton, Canada, which she helped to co-organise.

An article based on some of this work has been published in the journal Safundi.
