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.

Fight against Ebola virus requires more research

Dr Abdon Atangana, a postdoctoral researcher in the Institute for Groundwater Studies at the University of the Free State (UFS), wrote an article related to the Ebola virus: Modelling the Ebola haemorrhagic fever with the beta-derivative: Deathly infection disease in West African countries.

“The filoviruses belong to a virus family named filoviridae. This virus can cause unembellished haemorrhagic fever in humans and nonhuman monkeys. In literature, only two members of this virus family have been mentioned, namely the Marburg virus and the Ebola virus. However, so far only five species of the Ebola virus have been identified, including:  Ivory Coast, Sudan, Zaire, Reston and Bundibugyo.

“Among these families, the Ebola virus is the only member of the Zaire Ebola virus species and also the most dangerous, being responsible for the largest number of outbreaks.

“Ebola is an unusual, but fatal virus that causes bleeding inside and outside the body. As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes the blood-clotting levels in cells to drop. This leads to severe, uncontrollable bleeding.

Since all physical problems can be modelled via mathematical equation, Dr Atangana aimed in his research (the paper was published in BioMed Research International with impact factor 2.701) to analyse the spread of this deadly disease using mathematical equations. We shall propose a model underpinning the spread of this disease in a given Sub-Saharan African country,” he said.

The mathematical equations are used to predict the future behaviour of the disease, especially the spread of the disease among the targeted population. These mathematical equations are called differential equation and are only using the concept of rate of change over time.

However, there is several definitions for derivative, and the choice of the derivative used for such a model is very important, because the more accurate the model, the better results will be obtained.  The classical derivative describes the change of rate, but it is an approximation of the real velocity of the object under study. The beta derivative is the modification of the classical derivative that takes into account the time scale and also has a new parameter that can be considered as the fractional order.  

“I have used the beta derivative to model the spread of the fatal disease called Ebola, which has killed many people in the West African countries, including Nigeria, Sierra Leone, Guinea and Liberia, since December 2013,” he said.

The constructed mathematical equations were called Atangana’s Beta Ebola System of Equations (ABESE). “We did the investigation of the stable endemic points and presented the Eigen-Values using the Jacobian method. The homotopy decomposition method was used to solve the resulted system of equations. The convergence of the method was presented and some numerical simulations were done for different values of beta.

“The simulations showed that our model is more realistic for all betas less than 0.5.  The model revealed that, if there were no recovery precaution for a given population in a West African country, the entire population of that country would all die in a very short period of time, even if the total number of the infected population is very small.  In simple terms, the prediction revealed a fast spread of the virus among the targeted population. These results can be used to educate and inform people about the rapid spread of the deadly disease,” he said.

The spread of Ebola among people only occurs through direct contact with the blood or body fluids of a person after symptoms have developed. Body fluid that may contain the Ebola virus includes saliva, mucus, vomit, faeces, sweat, tears, breast milk, urine and semen. Entry points include the nose, mouth, eyes, open wounds, cuts and abrasions. Note should be taken that contact with objects contaminated by the virus, particularly needles and syringes, may also transmit the infection.

“Based on the predictions in this paper, we are calling on more research regarding this disease; in particular, we are calling on researchers to pay attention to finding an efficient cure or more effective prevention, to reduce the risk of contamination,” Dr Atangana said.
