Dr Alice Ncube says that since coming to South Africa and working with vulnerable communities in the disaster (risk) management field, she has gained extensive knowledge and perspectives on the real-life situations of humanity.

While working in human resources and industrial-relations management portfolios, Dr Alice Ncube saw a window of opportunity to get into research, focusing on the challenges that was threatening the human capital management sectors and the general operations of governments and the private sector. 

Today, Dr Ncube is teaching students and doing research in the Disaster Management Training and Education Centre (DiMTEC) at the University of the Free State (UFS), where she is a Senior Lecturer and Programme Director.

On 11 February – International Day of Women and Girls in Science – the UFS is celebrating Dr Ncube, who chose to be a scientist due to her desire to make a difference. 

Being a migrant facing several challenges in her host country motivated her to do her PhD on international migration, specifically on women from developing countries to other developing countries such as South Africa.

Her research also covers related topics, including social vulnerability and resilience, international forced migration, gender issues, climate change and adaptation, and sustainable livelihoods of disadvantaged communities.

Demystifying perceptions

“Many persons who do not reside in the country believe that South Africa is a land of opportunities – socially, politically, and economically – due to its position on the African continent. This all-round positive picture of the country painted to the outside world is the main reason for the huge inflow of migrants into the country,” believes Dr Ncube. 

She envisaged that her study would assist in demystifying the perception that migrants are those who come to a host country to take local jobs and put pressure on local resources.

“I felt that gender migration in this space is under-researched, particularly migration of women. Migration is not gender neutral, but gender biased, as evidenced by the 1960s and early 1970s, where terms such as ‘migrants and their families’ were coded to refer to male migrants and their wives and children. Although women were nearly invisible, there is evidence of them migrating as independent agencies and also taking along their families, including husbands,” she explains.

Exploring the coping and adaptation strategies that women employ in the host country, she found that although faced with many challenges, the migrant women cope and adapt well.

Her research as well as her work of more than 10 years with the vulnerable communities, including migrants, has established that the resilience of vulnerable communities is bigger than the intervention strategies that governments and other stakeholders envisage.

People are hungry for knowledge that will better their lives. – Dr Alice Ncube

Impacting lives

“Since coming to South Africa and working with vulnerable communities in the disaster (risk) management field, I have gained extensive knowledge and perspectives on the real-life situations of humanity, let alone in our continent and region,” she says.

She has worked with government departments at local, district, provincial, and national levels in an effort to change the conditions faced by poor, marginalised, and disadvantaged communities. Dr Ncube was also involved in community capacity-building activities through short courses and short learning programmes. 

She considers the training she has presented as one of the biggest achievements of her life. “People are hungry for knowledge that will better their lives.” 

“This has been so fulfilling to me as I have made an impact on the lives of the people,” says Dr Ncube.

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.
