Edwin Skhosana
Edwin Skhosana is working hard to become a successful and competent actuary one day. With him is his lecturer, Dr Michael von Maltitz.

Edwin Skhosana, an Actuarial Sciences student, was described by his lecturer, Dr Michael von Maltitz of the Department of Mathematical Statistics and Actuarial Science, as ‘very quiet’ in his Causal Inference class. 

This may sound like a compliment, but it’s not.

For Dr Von Maltitz, being quiet is definitely not encouraged – not with the new teaching methods applied in class.

“See, my class is all about engagement – getting the students to watch videos on the topics, read about the methods in question, and then come to class to grill me about things they don’t understand. This change in teaching method is extremely disconcerting for many Mathematical students, who have up until now only been taught in the ‘memorise-regurgitate’ form they had ever since the start of high school,” he explains.

Future success


“My goal is to get the students to a level of understanding where they can sit down with me or with an expert in the field and have a conversation about the Mathematical Statistics topics that I teach. This is a very difficult task in such a technical module, and few students ever feel comfortable enough to engage with me actively in class in this way,” Dr Von Maltitz points out. 

Edwin is working hard towards applying the skills and knowledge he has obtained at university to become a successful and competent actuary one day. 

An important turning point was when it dawned on him how the things discussed in class could find an important practical application in so many fields.  

“This suddenly drove a spontaneous fascination in my mind that led me to engage with Dr Von Maltitz,” the previously quiet Edwin explains.

And everything changed.

Desperate to learn

Dr Von Maltitz explains: “Edwin came to my office to ask some questions. The incredible thing was that he sat down, and a conversation about the Mathematics, the foundations, and the methods just flowed between us. I have seldom had such an insightful chat about my module with a student. It was like a cascade of information just fell into place for Edwin.”

Although he sometimes still experiences his studies as challenging and grapples to adapt to the various styles of lecturing from different lecturers, Edwin now has hope for his class in Causal Inference. 

“I think Dr Von Maltitz’s way of presenting in class is excellent. It is, however, hard to grasp if you are still anchored in the old way of cramming, because he wants you to understand and be able to apply what he teaches,” says Edwin.

“It was just wonderfully refreshing to see someone so desperate to learn something (rather than just wanting to get a degree), and then actually managing to turn around a bad semester mark into such a river of understanding,” Dr Von Maltitz concludes.

Researchers reach out across continents in giraffe research
2015-09-18

Dr Francois Deacon and Prof Fred Bercovitch
busy with field work.

Researcher Dr Francois Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State is conducting research with renowned wildlife scientist, Prof Fred Bercovitch, from the Center for International Collaboration and Advanced Studies in Primatology, Kyoto University Primate Research Institute in Japan.

Dr Deacon’s ground-breaking research has attracted international media attention. Together with Prof Nico Smit, he equipped giraffes with GPS collars, and conducted research based on this initiative. “Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.”

Prof Bercovitch was involved with GPS tracking from elephants to koala bears.

Some of the highlights of the joint research on giraffes by Dr Deacon and Prof Bercovitch focus on:
 
• How much time do certain giraffes spend with, and away from, one another
• How do the home ranges of herds and individual giraffe overlap
• Do genetically-related animals spend more time together than non-genetically-related animals
• How much time do the young bulls, adult bulls, and dominant bulls spend with cow herds
• Herd interactions and social behaviours of giraffe
• The role of the veld and diet on animal behaviour and distribution

 

Their research article, “Gazing at a giraffe gyroscope: Where are we going?”, which was published in the African Journal of Ecology, assesses recent research by exploring five primary questions:

- How many (sub) species of giraffe exist?
- What are the dynamics of giraffe herds?
- How do giraffe communicate?
- What is the role of sexual selection in giraffe reproduction?
- How many giraffe reside in Africa?

They conclude this article by emphasising that the most essential issue is to develop conservation management plans that will save a wonderful species from extinction, and which will also enable scientists to conduct additional research aimed at answering their five questions.

In addition, they are working together on a grand proposal to get National Geographic to cover their work.
