Embracing diversity, strengthening human relationships and collective responsibility

South Africa celebrated Human Rights Day and World Social Work Day on 21 March 2023. Social work is a profession that advocates for the human rights of people as well as focuses on the responsibility that comes with these rights. Just as the Bill of Rights is the cornerstone of democracy and protects our rights, the social work code of ethics is the cornerstone that ensures quality social work services.

The University of the Free State (UFS) second-year social work students took an oath on 22 March which binds them to the social work code of ethics. Social workers have the Global Agenda for Social Work and Social Development which consists of four pillars. Focus is drawn to the last pillar, Strengthening Recognition of the Importance of Human Relationships. Human relationships are the core of social work and social development. These relationships take various forms, including social, personal, interpersonal, and therapeutic relationships, among various people and in various settings. In relationships where people flourish, trust is crucial. In contrast, mistrust skews relationships in a negative way.

Respecting diversity through joint social action

The Ubuntu pan-African philosophical framework is the greatest place to understand the significance of human relationships. To promote and strive for the strengthening of relationships, this year’s theme for Social Work Day is “Respecting Diversity Through Joint Social Action”. If we can stop criticising people that do not live, believe, or think according to our constructed standards of being, we will be able to do so much more as humanity. If we start embracing peoples’ diversities and take time to start building relationships with various people and bridge any existing gaps, we will realise that diversity is an integral aspect of changing the world in a positive manner. Corresponding to human rights and the theme of World Social Work Day, is the theme “Destigmatising intellectual disability through shifting attitudes” for Intellectual Disability Awareness Month [IDAM] which also takes place later in March. Another way through which we can start building relationships and embrace diversity is by participating in this year’s South African Federation for Mental Health challenge where CEOs of different institutions are challenged to spend one day in a wheelchair as part of an awareness-raising campaign to destigmatise intellectual disabilities.

UFS involved in project to light up the townships

The parties involved with the project are from the left: Prof Hendrik Swart (Departmental Chairperson of the UFS Department of Physics), Dr Thembela Hillie (CSIR), Prof Neerich Revaprasadu (Department of Chemistry at the University of Zululand) and Dr Wynand Steyn (CSIR).

UFS involved in project that could light up the townships

The University of the Free State’s (UFS) Department of Physics is involved with a project that could make life easier in the townships through the use of artificial light.

“The project is based on the use of sunlight to activate nano material in for example cement and paint during the day. At night the cement or paint can then radiate light,” said Prof Hendrik Swart, Departmental Chairperson of the UFS Department of Physics.

According to Prof Swart an amount of R3,9 million has been made available by the Council for Scientific and Industrial Research (CSIR) for the further development of the project.

Prof Swart visited the University of Florida in America in 1995 for a year where he researched luminescent phosphor material that is suitable for flat panel television screens. The red, green and blue spots on the television screens originate from these kinds of phosphor materials. “At that stage plasma television screens were only a dream. Today it is sold everywhere,” said Prof Swart.

“Upon my return I started a research group at the UFS which investigated the degrading of phosphor material. We also started to concentrate on the effectiveness of nano phosphors. In the mean time our cooperation with the Americans was strengthened with follow-up visits to America of my colleagues, Prof Koos Terblans and Mr Martin Ntwaeaborwa,” said Prof Swart.

“Nano phosphors are basically luminescent powders that consist of particles that are 1 millionth of a millimetre. These particles can provide light as soon as they are illuminated with, for instance, sunlight. The amount of time these particles can provide light, is determined by the impurities in the material,” said Prof Swart.

According to Prof Swart nano particles are developed and linked to infrastructure materials in order for these materials to be excited during the day by sunlight and then it emits light during night time.

“The nano material is of such a nature that it can be mixed with materials, such as paint or cement. The yellow lines of roads can for example emit light in a natural way during night time,” said Prof Swart.

About a year ago Prof Swart and Dr Thembela Hillie, a former Ph D-student of the UFS Department of Physics, had discussions with Prof Neerich Revaprasadu from the University of Zululand and the CSIR about the possibility of mixing these nano phosphor particles with other materials that can be used as light sources in the building of roads and houses.

“Prof Revaprasadu is also actively involved in the research of nano materials. Our efforts resulted in the CSIR approving the further extension of the project,” said Prof Swart.

“The UFS and the University of Zululand are currently busy investigating ways to extend the light emitting time,” said Prof Swart.

“There are eight M Sc and Ph D-students from the UFS and about five students from the University of Zululand working on this research project. The Department of Physics at the Qwaqwa Campus of the UFS, with Francis Dejene as subject head, is also involved with the project,” said Prof Swart.

According to Prof Swart the further applications of nano materials are unlimited. “Children whose parents cannot afford electricity can for instance leave any object such as a lamp, that is covered with these phosphor particles, in the sun during the day and use it at night as a light for study purposes,” said Prof Swart.

According to Prof Swart the further extension of the project will take about two years. “During this time we want to determine how the effectiveness of the phosphors can be increased. Discussions with the government and other role players for the possible implementation of the project are also part of our planning,” said Prof Swart.
