Public lecture focuses on diversity as foundation for equality

The Free State Centre for Human Rights at the University of the Free State (UFS) held a public lecture at the Bloemfontein Campus on 30 January 2018 titled Putting religion in brackets: the importance of diversity in the public square by Prof Iain T Benson, Professor of Law at the University of Notre Dame in Sydney, Australia, and, for the past seven years, extraordinary Professor of Law at the UFS.

Conflict between religion and modernity
According to Prof Benson, there have been attempts to exclude so-called old-fashioned ideas from modernity. He gave examples of political and moral objections to public money being spent on religious education by schools, and the prevalence of terminology that stigmatises alternative opinions that may be based on religion, such as “homophobia”. He also referred to an instance in which the accreditation of a Canadian Christian university was challenged because its covenant explicitly rejected certain practices, such as extramarital relationships and same-sex marriage – the objections centred on an institution with such views receiving public benefits.

The challenge of inclusion in a growing secular society
Last year, a South African court found that schools may not promote a single faith to the exclusion of others. “According to the constitution, we have the right to hold religious beliefs. However, there are limitations on religious practices. Each society must draw a line,” he said. In the South African case, he explained, “the court rejected a blanket exclusion of religion in schools. If religion is a right, how can it be voted out of existence?”

Prof Benson argued that the ideology of secularism, the separation of church and state, is making inroads into how we understand religion. If agnostic or atheist viewpoints are accepted in the public sphere, it should not mean that religious beliefs should be abolished. “A diversity of beliefs should be accommodated and every citizen, whether religious or not, may be a part of public life,” he said. He concluded by saying that we lived in a particularly difficult time for a religious believer in the public sphere.

UFS researcher engineers metal surfaces
2015-03-03

Shaun Cronjé, a PhD student, in a surface characterisation laboratory at the UFS.

It is well known that the surface of a component is much more vulnerable to damage than the interior, and that surface-originated degradation such as wear, corrosion, and fracture will eventually destroy the component.

“Engineering the surface, based on scientific knowledge, is essential to control these damaging processes. It also creates electronic and geometric structures on the surface which opens up a world of new devices, especially considering the properties on the nano-length scale,” said Prof Wiets Roos from the Department of Physics at the University of the Free State (UFS).

At elevated temperatures, atoms are more mobile and can migrate to grain boundaries and surfaces, which have a major influence on material properties. The redistribution of solute atoms between the surface and the bulk of the material is known as segregation. Knowing the behaviour of segregation at the surface/environment interface can be very useful in the development of new materials. As an example materials can be improved higher efficiency and lower fuel consumption, thus reducing environmental pollution.

The main aims of Prof Roos’s research are to understand surface segregation, use it as a tool, and contribute to the various surface engineering fields.

The surface characterisation laboratories at the UFS are well equipped to do high temperature segregation measurements, and have already proven a success, not only in the ability to prepare the specimens for characterisation, but also in developing models and procedures to quantify the segregation parameters.

The most recent results have demonstrated the importance of taking evaporation into account during quantification.” This has laid the foundation for future studies by installing the necessary hardware in a surface characterisation spectrometer, establishing experimental protocols, and improving an existing model (developed in this laboratory) for simulating segregation profiles,” said Prof Roos.

Segregation parameters allow the researcher to predict and utilise the surface concentration behaviour as a function of temperature and time. “This not only contributes to fields involving corrosion, oxidation, sintering, wear, chemical poisoning, powder metallurgy, and lubrication but adds to the development of self-healing devices,” said Prof Roos.
