Dr Tembisa Leeuw – awarded her PhD at the UFS – focused her research on protecting the rights of children in conflict with the law and bridging the gap between policy and practice in child and youth care centres.

When Dr Tembisa Leeuw was in Grade 9, four of her classmates were convicted of serious offences, including assault with intent to cause harm and murder. This incident sparked a deep curiosity about the juvenile justice system and how it treats young offenders. She found herself asking difficult questions: Were her peers detained separately from adults? Were they placed in facilities designed specifically for children?

Despite the crimes her classmates committed, Dr Leeuw believed they still needed care and protection. The experience led her to reflect on society’s responsibilities towards young offenders, the difficulties they face in the justice system, and whether the laws meant to protect them are being properly applied. “This formative experience instilled in me a commitment to advocate for the rights of vulnerable children and to ensure that the juvenile justice system upholds principles of care, protection, and rehabilitation,” she says.

Now a human rights officer at the South African Human Rights Commission based in Mpumalanga, Dr Leeuw was recently awarded a Doctor of Philosophy degree at the University of the Free State’s (UFS) autumn graduation ceremony. Her dissertation is titled Protecting the rights of children in conflict with the law in South Africa: The law versus the practice.

Her supervisor, Prof John Mubangizi – Research Professor in the Free State Centre for Human Rights – said it was an absolute privilege to supervise such a brilliant, dedicated, and hard-working student. “Her intellectual curiosity, resolute determination, and unwavering commitment to excellence have been quite inspiring. I have no doubt that she will continue to make a profound impact wherever she goes and whatever she does henceforth.”


Safeguarding the rights and well-being of children

It is well known that a large share of crimes, particularly violent ones, are committed by young people. In South Africa, children are frequently charged with serious offences, such as robbery, rape, assault, and murder. These realities highlight the need for stronger systems that protect the rights and well-being of young people in conflict with the law.

In her research, Dr Leeuw looked at why children in child and youth care centres often face human rights violations, despite the Constitution guaranteeing every child the right to be safe from harm, neglect, and abuse. 

Her findings revealed troubling gaps between what the law says and what happens in practice. According to Dr Leeuw, the Constitution states that children should only be detained as a last resort and for the shortest time possible. UNICEF also emphasises that children must be kept separate from adults in detention and treated in ways that reflect their age and developmental needs, including their right to education. “However, no country has yet built a fully separate juvenile justice system that ensures that children are treated differently from adults,” she says.

Dr Leeuw also found that children in these facilities are often denied access to education. As a result, when they return to their communities, they are often without the skills or qualifications needed to find work. “It is important that these children receive training that enables them to support themselves,” she explains.


Contributing to a humane and equitable society

Dr Leeuw believes that protecting the rights of children in conflict with the law is important to creating a more just and humane society. “Research shows worrying conditions in child and youth care centres (CYCCs) – overcrowding, poor health care, limited education. Many children report violence, intimidation, and neglect, all of which go against the idea of rehabilitation,” she says.

These environments can deepen trauma and increase the chances of reoffending. “The conditions inside detention centres have a serious impact on children's ability to rehabilitate and move forward in life.”

South Africa has made progress in drafting laws to protect children’s rights, but putting those laws into action is still a challenge. “With the right changes and a more caring approach, the justice system can better meet the needs of children,” Dr Leeuw says. She points to several areas where improvements could be made to help policy makers and human rights workers reform juvenile justice.

She notes that although international agreements promote rehabilitation and support, many CYCCs still focus on punishment. “Children often feel abandoned in these spaces. We need to move away from punitive systems and create pathways for healing and reintegration.”

Government departments, such as social development, education, and health, must work together to provide support that meets children's full range of needs. “Current laws must be updated to meet international standards, and programmes are needed to help guide children away from the justice system in the first place,” she adds.

Dr Leeuw also highlights the key role played by child and youth care workers (CYCWs). Their training and regular oversight are important in making sure children’s rights are respected. “Regular monitoring and open reporting are needed to hold facilities accountable,” she says.

She further stresses the need for greater access to mental health support, education, and skills development. This would help children return to school and integrate into society more easily. She also recommends maintaining strong family ties during rehabilitation, including virtual visits for families who live far away. Addressing overcrowding and offering different forms of intervention can also improve care and reduce reoffending.

“Teaching children about their rights and helping them develop a sense of responsibility is just as important. Programmes that promote personal growth and rehabilitation should be part of their daily lives,” she says.


Aligning with international human rights standards

Dr Leeuw’s study closely aligns with international human rights guidelines on juvenile justice. These include the United Nations Convention on the Rights of the Child (UNCRC) and other global frameworks that call for dignity, fairness, and restorative justice in how children are treated. Her work highlights the need to address the root causes of children's behaviour and calls for tailored responses, such as alternatives to incarceration, fair sentencing, and stronger legal protection.

The study also highlights the importance of prevention. Involving communities, improving access to education, and introducing early support systems can help reduce the number of children who come into contact with the justice system. She believes that juvenile justice systems must ultimately uphold the dignity and fair treatment of children, as outlined in both international frameworks and the South African Constitution.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
