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.

In her inaugural lecture, Prof Helene Strauss explores symbols that reflect our history

Prof Helene Strauss did not disappoint in her highly-anticipated inaugural lecture “The Spectacles of Promise and Disappointment: Political Emotion and Quotidian Aesthetics in Post-transitional South Africa”. She posed some very challenging ideas on the promises and disappointments that arouse from apartheid. Prof Strauss pointed to the fact that “… a promise must promise to be kept; that is, not to remain spiritual or abstract, but to produce events, new effective forms of action, practice, organisation, and so forth.”

She underscored the message of her lecture by making use of the image of a burning tyre – a symbol commonly associated with apartheid. This act of ‘necklacing’ is closely connected to the violence and protests of that era. Prof Strauss used this image to represent an array of social concerns: global mass protest, modernity and mobility, waste economies and waste management, environmental destruction, as well as poverty and resistance in varied formats.

Some of South Africa’s greatest artists have used the burning tyre in their work, particularlyBerni Searle and Zanele Muhloi. Not only does it trigger the shadow of the damaging past, but “more recently, it has come to figure also in the spectacles of promise and disappointment that have marked the country’s transitional and post-transitional periods,” Prof Strauss remarked.

Prof Strauss focuses her research on these symbolisms in our history because of “the questions that they raise about the emotional cultures produced in the aftermath of apartheid and for the unique contribution that they make to current debates on political and aesthetic activism.”Her passion for this subject comes from the “affective or emotional legacies of various forms of structural inequality, an interest that owes a sizeable debt to postcolonial, queer and feminist critical theory and creative work of the past hundred or so years.”

Prof Strauss accepted a position at the University of the Free Sate in 2011 and currently works in the Department of English. She is part of the Vice-Chancellor’s Prestige Scholars Programme and holds a PhD from the University of Western Ontario. Previously, she held the position of Assistant Professor in the Department of English and Cultural Studies at McMaster University in Canada, where she resided for 11 years.

Among the guests were Prof Jonathan Jansen, Profs Botes and Witthuhn, lecturers in the Department of English, members of the Faculty of the Humanities, students and some of Prof Strauss’ colleagues from Canada.
