Education researcher tackles realities of Fourth Industrial Revolution
Dr Makeresemese Qhosola recently engaged audiences in New York at the American Educational Research Association’s Annual Conference.

The current research of Dr Makeresemese Qhosola, from the University of the Free State’s (UFS), Faculty of Education focused on a broad theme of accounting and its alignment to the Fourth Industrial Revolution. She is passionate about it because the role of accounting has evolved over the years in response to ever-changing market demands. It evolved from the First Industrial Revolution, which focused on the size of a factory, machinery and the labour force, and now it is concerned with the looming era of artificial intelligence and the internet of things.

Tackling the present for future solutions  
Dr Qhosola’s research is important because it interrogates the past to find solutions for the future. “The curriculum of South Africa is still challenged by the imperatives of the Third Industrial Revolution which saw the automation of the accounting process and other business processes in isolation from each other. This challenge is born of historical factors that are still inherent in the contemporary, like poverty in most South African communities, and a lack of infrastructure and resources that supported this industry and demanded learners be taught automated accounting like Pastel.
 
“Even though learners are mostly exposed to the basic knowledge and skill of accounting from schools, many of them seem to be dysfunctional when they join the world of work, due to a lack of knowledge and experience of the computerised systems,” purported Dr Qhosola.
 
Her research methodology is the Participatory Action Research (PAR) approach and is supported with the use of the Critical Accounting Research (CAR). “I use it as my lens of choice for framing my project, because its purpose is to ensure the use of accounting does not represent a certain interest at the expense of others, especially marginalised groups,” said Dr Qhosola.
 
Future of accounting looks good
“The question remains: ‘How do we better prepare ourselves for this revolution that seems capable of rendering many accounting jobs redundant?’ We must thoroughly prepare our students for the job market after the completion of their studies.” 
 
Dr Qhosola owes her recent success to Prof Loyiso Jita, Dean of the UFS Faculty of Education. “He initiated a mentorship programme for black women in 2017 and it has created a platform for me to go out and learn more,” she said. She also holds former UFS Dean of Education, Prof Sechaba Mahlomaholo close to her heart, because of his continued mentorship and support through the world of academia. 

International recognition and achievement 

Dr Qhosola was recently invited to the American Educational Research Association (AERA), in New York. The AERA strives to advance knowledge about education, to encourage scholarly inquiry related to education, and to promote the use of research to improve education and serve the public good.
 
The conference provides an opportunity to learn about new developments and current issues that require the attention of researchers. It is also a good platform to meet educational proponents and theorists from across the globe. “We read and use their work almost every day and never get an opportunity to meet them and really interact with them,” said Dr Qhosola.
 
A proposal acceptance from AERA is a recognised disciplinary achievement. The AERA conference is a highly competitive peer review process because there are 12 000 to 14 000 proposals a year that compete for a slot on the conference programme. These numbers include both experienced and beginner researchers.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
