Jon Jacobson
Delivering the 31st Sophia Gray Memorial Lecture and Exhibition in Bloemfontein, was Jon Jacobson from Metropolis Design in Cape Town.

What is inside and what is outside? What is coming alive in the light? Minimalism. Hugeness. Shadows. Soft. Art. Complex. Conversation. Ambiguity. Clarity. All phrases and words used by the most recent Sophia Gray laureate, Jon Jacobson from Metropolis Design in Cape Town, to describe aspects of his work.

He delivered the 31st Sophia Gray memorial lecture in Bloemfontein. The name of his lecture at this prestigious event, organised by the UUFS Department of Architecture, was in [de] finite. Jacobson is the first graduate in the department’s MArch with Design.

Nature plays a big role in many of his projects, with a blurred distinction between the inside and the outside of the structures he builds. His designs fulfil the desire of a union with nature. 

A detailed investigation

Jacobson creates places and spaces to celebrate being. “Architecture is undeniably art, but it is also embodied in the completeness of the lived moment,” he says. 

Every project starts with a detailed investigation. “What social theory will we engage with? How progressive is it? What attitude will we take to the environment, to the theory of family? What other personal concerns will we be worried about? It is important to engage critically with this information. Important to build a philosophical base for each project,” says Jacobson.

He also believes it is important to consciously ensure that form follows idea with the same intensity that it follows function and that it does not blindly follow other form. 

At Metropolis, Jon and his team are client centred in their approach to design. Jon explains the process: “Some of the content is brought from the client’s personal and social aspiration and some from contemporary architecture culture, but the most potent component is the hidden set of ideas that emerge from our own engagements with the living world such as popular science, geology, art, music, literature, philosophy, theology, mysticism, and many others. And this emerges in the hidden sense of the word, in its architecture content.”

Content approach to design

In house design, Jon categorises the content that informs the architecture of the house: content pertaining to the individual, their philosophy, values and beliefs, content derived from culture, architecture and the arts, passion, religion, politics, and content referring to the natural world and its processes. Content from each of these spheres is present in any of his work. 

Jon says a major implication of a content approach to design is that it requires a design framework that is largely operative at a level of idea rather than at the level of form. This contributes to creating architecture rather than just buildings. 

His design method allows conscious control over the relationship between the ideas, the forms, and the poetics of the projects. “And at any point in the building process, it is possible to trace back and to critically assess whether any particular form is aligning with the core ideas of the project,” Jon indicates. 

Jon’s first taste of grappling with the infinite of architecture was with a garden pavilion he built for rest and relaxation. “For the first time I felt that we integrated planning, content, sight, programme, structure, and materiality into one unified whole that was expressed with a minimum of means and that was more than just the sum of its part,” he states.

He strongly believes that the individual is at the centre of every architectural project. He says the belief systems, type of social needs, family dynamics, physical habits, and spatial practices of their clients need to be investigated in detail in order to facilitate a meaningful spatial experience.

He continues: “We see our role as designers to saturate the environment with the meaning that enhances our clients’ daily experience in every possible way – from the ergonomic and the practical to the spiritual. In the process, the logics and tradition of architecture and the ego of the architect sometimes need to make way for human need and aspiration.”

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.
