The science of safety

UFS Protection Services — The science of safety reinforces practical and collaborative efforts aimed at creating a secure campus environment.

While we might not have it down to a science just yet, safety is something that the University of the Free State (UFS) is constantly working towards improving. As it stands, various preventative measures exist across our three campuses. They say “Prevention is better than cure” – and that is exactly what the science of safety is all about.

What is the university doing to prevent crime?

There are a few measures put in place by the Department of Protection Services, as its core mandate involves working around the clock to address the state of safety and security for staff and students. Some of these measures include:

• CCTV cameras monitoring campuses on a 24/7 basis.

• Panic buttons mounted on red poles which are fitted with cameras linked to the Control Room.

• Daily visible vehicle and foot patrols conducted by security personnel.

• Security infrastructure such as turnstiles and surveillance cameras installed on all residence entrances.

• Security officers deployed around residences at night.

• Closely collaborating with Housing and Residence Affairs to find ways of creating, maintaining, and improving off-campus student safety.

• Investigating Officer on a 24/7 standby who is in direct contact with the South African Police Service (SAPS) Investigation Unit.

• Security and SAPS vehicles deployed at identified hotspots.

• Security patrols by contracted armed response security companies conducted in areas such as Brandwag, Willows, and Universitas in Bloemfontein, and surrounding areas at the Qwaqwa and South Campuses.

Safety is a shared responsibility

“In as much as Protection Services has duties and responsibilities in ensuring the safety of staff and students, the UFS community also needs to support and provide assistance to the department,” said Cobus van Jaarsveld, the department’s Section Head: Threat Detection, Investigations, and Liaison.

You can play a role in ensuring that the UFS becomes an increasingly safe environment by:

• Immediately reporting any suspicious activity, item, person, or vehicle to the Department of Protection Services.

• Acting responsibly to minimise your vulnerability to criminal activities.

• Familiarising yourself and complying with the UFS Security Policy, Protest Management Policy, and other security guidelines, standards, procedures, and protocols.

• Following instructions issued by an authorised person for safety and security reasons.

• Cooperating with investigation processes that are in the interest of justice.

• Treating university property with the utmost care and avoiding exposing it to criminal activities, as well as reporting such activities.

Creating a safe space for all

From identifying safety needs to tackling security issues head-on, the Department of Protection Services strives to reduce the risk of all kinds of crimes through the science of safety. The department continuously responds to the call to serve and protect in the following ways:

• Identifying and assessing risks and threats that have an impact on the safety and security of the UFS staff, students, and property.

• Enforcing access control.

• Investigating any reported incidents, providing investigation reports, and also issuing early-warning reports.

• Responding to emergencies reported on campuses.

• Advising UFS management on all aspects of security.

• Initiating programmes and projects to enhance security awareness among UFS staff, students, visitors, and contractors.

• Providing support to students living in off-campus residences through contracted armed response that responds to emergencies and conducts patrols.

• Arranging counselling for victims of crime where necessary.

• Coordinating security services for on-campus events to ensure a safe and secure environment.

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.
