Prof Abdon Antangana
Prof Abdon Atangana, a Professor of Applied Mathematics in the Institute for Groundwater Studies at the University of the Free State (UFS) and South Africa’s top-ranked scientist in Mathematics, wants to prepare the next generation of African professors.

A new book written by Prof Abdon Atangana, Professor of Applied Mathematics at the Institute for Groundwater Studies at the University of the Free State (UFS), in collaboration with one of his students, on the flow of groundwater, suggests several new and modified models to better predict anomalous behaviours of the flow and the movement of pollution within complex geological formations.

Mathematical Analysis of Groundwater Flow Models is one of two books Prof Atangana published recently that he wrote with his students. The other, Fractional Stochastic Differential Equations: Applications to Covid-19 Modeling, provides a thorough conversation on the underpinnings of COVID-19 spread modelling. He wrote the book with a postdoctoral fellow, Dr Seda Araz Igret from SIIRT University, Turkey. Since 2016 he has published a total number of six books, some of which are still under evaluation by Springer and Elsevier.

Time to prepare next generation of African professors 

This highly cited researcher is excited about collaborating with his students on projects such as these as he feels it is time for him to prepare the way for the next generation of African professors. Prof Atangana is ranked at No 219 in the world rankings and No 1 in South Africa by Research.com, a leading academic platform for researchers. 

According to the platform, which recently released the 2022 Edition of its Ranking of Top 1000 Scientists in the field of Mathematics, the ranking is based on the H-index metric provided by Microsoft Academic and includes only leading scientists with an H-index of at least 30 for academic publications in the field of Mathematics.

“Both books are important for me because they are first-time published books with my own students. There is a time to prepare the way for yourself and a time to prepare ways for the next generation. It is time for me to prepare the way for the next generation of African professors. I wish that the next time this list (https://research.com/scientists-rankings/mathematics/za) [is released] many of my students [will] appear,” says Prof Atangana.

About his book with Dr Igret, he says it presents the dynamic of COVID-19 spread behaviour worldwide. It is noticed that the spread dynamic followed process with nonlocal behaviours, which resemble power law, fading memory, crossover, and stochastic behaviours. Fractional stochastic differential equations are therefore used to model spread behaviours in different parts of the world. 

“The content coverage includes a brief history of COVID-19 spread worldwide from December 2019 to September 2021, followed by statistical analysis of collected data for infected, death and recovery classes,” says Prof Atangana.

Mathematical analysis of Groundwater Flow Models serves as a valuable resource for graduate and PhD students as well as researchers working within the field of groundwater modelling, says Prof Atangana. It includes features such as:
• Modified numerical and analytical methods for solving new and modified models for groundwater flow and transport 
• New flow and transform models for groundwater transport in complex geological formations 
• Examination of fractal and crossover behaviours and their mathematical formulations

Top-ranking scientist 

Prof Atangana was also recently elected as a fellow of The World Academy of Sciences (TWAS) and received the World Academy of Sciences Award for Mathematics (TWAS -Mohammad A Hamdan, 2020) on 1 November 2021.

Very recently, he was also ranked No 1 in the world in Mathematics, No 186 in the world in all the fields, and No 1 in Africa in all the fields, according to the Stanford list of 2% single-year table.

He was also named among the top 1% of scientists on the global Clarivate Web of Science list. Fewer than 6 200 or 0.1% of the world’s researchers were included on this list in 2019, 2020 and 2021, with fewer than 10 of the scientists hailing from South Africa. 

“While my name is ranked No 1 in South Africa and No 219 in the world, this shows the impact of my research that has been done since 2013. It is worth noting that this ranking disadvantages younger researchers. For example, I got my first publication in 2013 but the researcher who was ranked No 1 started in 1972. To make the ranking fair, the total H-index should be divided by the number of years of publication. I am very proud to see that despite this disadvantage I am still topping in South Africa and am No 219 in the world.”

Resource Manual on Trafficking in Persons for Judicial Officers sees the light

On Human Rights Day the Department of Criminal and Medical Law in the Faculty of Law at the University of the Free State (UFS) hosted the launch of the Resource Manual on Trafficking in Persons for Judicial Officers compiled by the South African Chapter of the International Association of Women Judges (SAC-IAWJ).

The manual, which will be used by members of the South African judiciary, will equip officials in adjudicating the multifaceted crime of human trafficking.

“Presiding officers must be sensitised about the complexity of the crime. Human trafficking has many faces and presents itself in different ways. A person may for example be trafficked for sexual exploitation, forced labour, the removal of body parts, as well as forced marriages. Expert knowledge is needed to handle these cases effectively in court,” said Dr Kruger, also responsible for the human trafficking initiative in the Unit for Children's Rights at the UFS.

Prior to the launch, a total number of 300 judicial officers, including six judges from the Southern African Development Community (SADC) received training on human trafficking. After receiving this training, the officers were sensitised to scrutinise domestic violence cases as well as inter-country adoption cases in order to identify possible human trafficking activities.

As keynote speaker at the launch, Dr Beatri Kruger from the Department of Criminal and Medical Law at the UFS, said that human traffickers were running operations like a well-oiled machine. They have abundant and sophisticated resources and often bribe corrupt officials to further their criminal activities. In South Africa, people combating human trafficking struggle with a lack of resources as well as comprehensive legislation. Most cases are prosecuted under the Children’s Act and the Sexual Offences Amendment Act of 2007. Unfortunately, this legislation still leaves a gap in the prosecuting of perpetrators. Only trafficking cases where where children are trafficked can be prosecuted under the Children’s Act. In terms of the Sexual Offences Amendment Act perpetrators can be prosecuted for trafficking persons for sexual exploitation only, and not for labour of other forms of trafficking. Therefore the comprehensive Prevention and Combating of Trafficking in Persons Bill 2010 needs to be finalised to cover all forms of trafficking.

There are more slaves today than at any time in the history of humankind. “To combat this serious problem, we need to follow a holistic approach,” said Dr Kruger. This includes prevention (raising awareness), effective prosecution and suitable punishment, the protection of victims, and partnering with all relevant stakeholders, including people in the communities. Community members are often whistle blowers of this crime.

The President of the SAC-IAWJ, Judge Connie Mocumi, handed copies of the manual, a three-year project, to judicial officers present at the launch. The manual covers, among others, the definition of trafficking in persons, trafficking in persons in South Africa and the Southern African region, a legislative framework, victims’ rights and criminal proceedings.

“It is critical that judicial officers appreciate the phenomenon of trafficking in persons in its broader socio-economic context. Therein lays the ability to deal competently with the often-nuanced manifestation of this scourge. The incapacity to recognise these nuances can deny victims access to justice. In that regard, the manual, amongst others, is to become an important empowering adjudication tool for judicial officers,” said Judge Mocumi.

More copies will be printed and be ready for distribution by the beginning of May this year.

Judge Belinda van Heerden, who also attended the launch, said: “There is progress on the judicial and legislative front to bring wrongdoers to book. This manual will go a long way in giving judicial officers insight into the problem.”
