Prof Maxim Finkelstein, A1-rated researcher from the University of the Free State, has been selected as the 2024 - 2026 Ewha Global Fellow by Ewha Womans University.

An esteemed researcher from the University of the Free State (UFS), Prof Maxim Finkelstein, has been named a 2024 - 2026 Ewha Global Fellow (EGF) by Ewha Womans University in South Korea.

Prof Finkelstein, an A1-rated researcher from the Department of Mathematical Statistics and Actuarial Science, received this honour in recognition of his outstanding collaboration with Prof Ji Hwan Cha from Ewha’s Department of Statistics. Prof Cha nominated him as a leading expert in his field, highlighting their long-standing partnership and significant contributions to mathematical sciences.

According to Hyang-Sook Lee, President of the Ewha Womans University, the EGF programme “encourages distinguished scholars from all over the world to actively collaborate in research and education with Ewha faculty members.”

 

The genesis of a unique collaboration

Prof Finkelstein has collaborated extensively with researchers across Europe and the United States but his partnership with Prof Cha is particularly notable. “I started working at the UFS as a Professor in 1998 when he had just obtained his PhD,” recalls Prof Finkelstein.

At the time, Prof Finkelstein was already an established researcher, while Prof Cha was in the early stages. “His letter to me about one of my articles was sent to me by regular mail to my previous working address in Saint Petersburg, Russia, and did not reach me. We eventually connected around 2006, and our collaboration gradually took shape,” he explains.

Over the years, their partnership evolved into a balanced and mutually enriching research relationship. Their joint efforts have resulted in over 120 published papers and two books, setting new standards in the Mathematical Theory of Reliability and its applications. This collaboration has significantly influenced both their careers and contributed to Prof Finkelstein’s recognition with South Africa’s highest research accolades, including an NRF A1 rating in "Mathematical Sciences" in 2021, following his A2 rating in 2015.

 

A breakthrough in stochastic modelling

One of the major achievements of Prof Finkelstein's collaboration with Ewha has been their pioneering work in stochastic modelling. Their research led to the development of the Generalised Polya Process, a novel model for understanding natural and industrial point events - such as failures in electricity generation, lightning strikes, and hurricanes. By incorporating the ‘history’ of previous events, this model offers a more precise stochastic description of real-world phenomena.

The results of their research have been widely published and have paved the way for further exploration into more complex stochastic processes. Some of their key findings were summarised in the 2018 Springer book Point Processes for Reliability Analysis.

 

Looking ahead: Future collaboration and continued innovation

Despite being in the later years of his career, Prof Finkelstein remains deeply engaged in research and committed to his partnership with Ewha. Due to the challenges posed by the COVID-19 pandemic, his visits to Ewha were limited, but plans are now in place for future visits. During these visits, he will deliver lectures to students and collaborate with faculty members.

For Prof Finkelstein, continuing his nearly two-decade-long collaboration with Prof Cha remains a vital and exciting part of his academic journey.

Emma Sadleir talks about social media etiquette

“We have all become celebrities, we have become social figures because of our power to publish information. We have all become brands, and we need to protect our brand. Digital content is sometimes dangerous content,” said Sadleir.

On 11 May 2016, the University of the Free State, in collaboration with the Postgraduate School, hosted, Emma Sadleir, a leading social media expert, in the Equitas Auditorium on the Bloemfontein Campus. She is an admitted advocate, specialising in social media law.  Dr Henriette van den Berg, Director of the Postgraduate School, described Sadleir’s presentation as a privilege for all the staff and students who attended.

Sadleir said that there are two important rules that staff and students of an institution should try to follow. The first is not to bring the name of the institution into disrepute; and the second is not to breach the goodwill of the institution or, in other words, not to bite the hand that feeds you.

“The common law, even if there is no policy, is that anything that brings the company into disrepute can lead to disciplinary consequences up to termination,” said Sadleir.

Sadleir focused on hate speech and free speech, stating that free speech is a right that is entrenched in the constitution, but, like every other right, it has limitations. She mentioned Penny Sparrow, Matt Theunissen, Velaphi Khumalo, and Judge Mabel Jansen, all of whom have been lambasted by the public over their racist posts on social media. Sadleir stressed that, even on social media, content has to be within the confines of the law, and people must remember our rights are not absolute. We have a lot of freedoms, but no one cannot disseminate hate speech.

“Would you publish whatever you thinking on a billboard, close to a busy highway with your name, picture and employers details or the institution you studying at? If you have no grounds to justify the comment, do not post it,” warned Sadlier.  

According to the South African Bill of Rights, everyone has the right to privacy, but an expectation of privacy has to be enforced. She said people over-document their lives on social media, decreasing your right to privacy drastically. “It is like CCTV footage of your life. It is simple, the more you take care of your privacy, the more you have,” said Sadleir.

Sadleir said it was important for Facebook users to have privacy settings where they can review posts where they are tagged. According to Sadleir, managing your reputation is not only limited to what you post about yourself but also managing what others post about you.

She cited a 2013 case in the Pretoria High Court in which a new wife wrote a scandalous Facebook post about her husband’s ex-wife, tagging the husband in the post. The courts found both the new wife and the husband guilty of defamation.

“If you have been tagged in something but have not been online and seen the content, you are then an innocent disseminator. The moment you are aware of the post you are liable for the content,” said Sadleir.

“It takes 20 years to build a reputation and five minutes to ruin it. If you think about that, you'll do things differently,” Sadleir said, concluding her presentation with the quotation from Warren Buffet.
