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.

Universities join hands in developing literacy tests

The development of academic literacy tests recently took a step into the future with the formal establishment of the Inter-institutional Centre for Language Development and Assessment (ICELDA).

ICELDA, under its first executive head, Prof. Albert Weideman, Head of the Department of English at the University of the Free State (UFS), is a cooperative venture between the multilingual Universities of Pretoria, North-West, Stellenbosch and the Free State.

It is dedicated to the development of reliable state-of-the-art academic literacy tests and currently makes 32 000 tests available to partnering universities annually.

Most notably, it has produced three of the most reliable academic literacy tests in the country. These include an Academic Listening Test and the Test of Academic Literacy Levels (TALL) for undergraduate students, with reliability levels that are more than 20% above international benchmarks.

“We are even more excited about our Test of Academic Literacy for Postgraduate Students (TALPS), which is already a crucial instrument in determining the literacy levels of postgraduate students at the Universities of the Free State, Pretoria and North-West,” said Prof. Weideman.

In addition, ICELDA is currently piloting studies for language tests for financial advisors, nurses, students of disaster management, as well as police studies at Unisa.

ICELDA will also collaborate with the Centre for English Language Communication (CELC) at the National University of Singapore.

“One of the undertakings I made on my visit to Singapore a year ago was that I would assist in every way I could with the building of joint expertise with CELC in language testing,” said Prof. Weideman.

“However, our focus will remain firmly on research.”

He said his goal was to employ the surpluses generated by selling tests to provide promising students with bursaries to stimulate further study and design of academic literacy and other language tests.

By drawing more researchers into the field, Weideman said, ICELDA could provide the capacity for developing reliable language tests that South Africa had always lacked.
