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.

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.

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.
