Leading a happy and productive workplace - Susan van Jaarsveld

Susan van Jaarsveld is the Senior Director: Human Resources at the University of the Free State. Since the HR department is the ‘go-to person’ for all employee-related matters, her duties involve managing activities such as recruitment and selection, employee relations, performance management, training and development, and talent management. “As the employees are the most important asset, we have to ensure a happy and productive workplace,” she explains. 

What is the best thing about your job?
You always move between what is good for the UFS and what is good for the employees, and you have to build that bridge and find a good balance. The best part is that you can really make a difference – for an employee or a team – by helping them to let their (hidden) talents come to life and helping them realise their dreams.

What is the best and worst decision you have ever made?
Two of the best decisions I ever made were to have my two amazing children. They have enriched my life and I cannot imagine a world without them in it. I made many bad decisions, but I choose not to dwell on those. In hindsight, many of these bad decisions taught me valuable life lessons and also led me to wonderful new opportunities.

What was/is the biggest challenge of your career?
The biggest challenge throughout my career was to balance my work and home life. This is certainly a challenge that many people, especially women, can relate to. It means constantly feeling guilty. When I was at work, I felt guilty that I’m missing out on important parts of my children’s lives, and I felt guilty when I was spending time with my family and not working. My children are both grown-up now and maintaining a balance between my home and work life has become easier.

What does the word woman mean to you?
Being a woman is complicated, multi-faceted, and often unfair. Womanhood is about strength, love, and compassion; a human being who can be powerful and assertive and kind at the same time.

Which woman inspires you, and why?
I am inspired by South African women, the single mothers who raise their children in difficult circumstances, the ones who make ends meet every day, the CEOs who manage big companies successfully, the ones who are battered and bruised by life and other people but still keep going, the health workers who are carrying us through this COVID-19 pandemic, the ones who stand up against injustice and say, ‘when you strike a woman, you strike a rock’.

What advice would you give to the 15-year-old you?
You are enough! Relax and enjoy life to the fullest.

What is the one self-care thing that you do? 
I exercise regularly, it helps me to stay healthy in body and mind.

What makes you a woman of quality, impact, and care?
I choose to be positive, fair, and caring in everything I do. It is a privilege to be part of the UFS, where I strive to continuously improve the institutional culture, together with a very supporting and competent team. Care (commitment, attraction, retention, excellence) is the acronym that best describes the vision of the HR team; we care and incorporate this into every initiative we undertake.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
