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.

UFS research sheds light on service delivery protests in South Africa

UFS research sheds light on service delivery protests in South Africa

Service delivery protests in the country have peaked during 2014, with 176 major service delivery protests staged against local government across South Africa.

A study by the University of the Free State (UFS) found that many of these protests are led by individuals who previously held key positions within the ANC and prominent community leaders. Many of these protests involved violence, and the destruction had a devastating impact on the communities involved.

This study was done by Dr Sethulego Matebesi, researcher and senior lecturer at the UFS. He focused his research on the dynamics of service delivery protests in South Africa.

Service delivery protests refer to the collective taken by a group of community members which are directed against a local municipality over poor or inadequate provision of basic services, and a wider spectrum of concerns including, for example, housing, infrastructural developments, and corruption.

These protests increased substantially from about 10 in 2004 to 111 in 2010, reaching unprecedented levels with 176 during 2014.

The causes of these protests are divided into three broad categories: systemic (maladministration, fraud, nepotism and corruption); structural (healthcare, poverty, unemployment and land issues); and governance (limited opportunities for civic participation, lack of accountability, weak leadership and the erosion of public confidence in leadership).

In his research, Dr Matebesi observed and studied protests in the Free State, Northern Cape and the North-West since 2008. He found that these protests can be divided into two groups, each with its own characteristics.

“On the one side you have highly fragmented residents’ groups that often use intimidation and violence in predominantly black communities. On the other side, there are highly structured ratepayers’ associations that primarily uses the withholding of municipal rates and taxes in predominantly white communities.”

 

Who are the typical protesters?

Dr Matebesi’s study results show that in most instances, protests in black areas are led by individuals who previously held key positions within the ANC - prominent community leaders. Generally, though, protests are supported by predominantly unemployed, young residents.

“However, judging by election results immediately after protests, the study revealed that the ANC is not losing votes over such actions.”

The study found that in the case of the structured ratepayers’ associations, the groups are led by different segments of the community, including professionals such as attorneys, accountants and even former municipal managers.

Dr Matebesi says that although many protests in black communities often turned out violent, protest leaders stated that they never planned to embark on violent protests.

“They claimed that is was often attitude (towards the protesters), reaction of the police and the lack of government’s interest in their grievances that sparked violence.”

Totally different to this is the form of peaceful protests that involves sanctioning. This requires restraint and coordination, which only a highly structured group can provide.

“The study demonstrates that the effects of service delivery protests have been tangible and visible in South Africa, with almost daily reports of violent confrontations with police, extensive damage to property, looting of businesses, and at times, the injuring or even killing of civilians. With the increase of violence, the space for building trust between the state and civil society is decreasing.”
