"Disability describes the social exclusion and barriers imposed on people with disabilities and impairments evoke an unpleasant feeling in us, and it is the feeling which motivates how we react when we face disability and people with disabilities." – Brian Watermeyer 

South Africa commemorates National Disability Rights Month, known as DRAM, annually between 3 November and 3 December. International Day of Persons with Disabilities, also known as National Disability Rights Awareness Day, is celebrated on 3 December. The theme for 2021 is ‘The Year of Charlotte Manye Maxeke – Create and Realise an Inclusive Society Upholding Rights of Persons with Disabilities’. 

Disability is a quintessential post-modern concept, because it is complex, variable, contingent, and situated. One is always disabled concerning the context in which you are put, subject to many definitions from different perspectives, and is used for various disciplines ranging from medicine, sociology, and political science. To fully comprehend disability, one needs to consider multiple perception models in the quest for a better understanding of disability; so-called ‘models of disability’ emerge in disability research. In line with most notions of disability, it could be associated with the medical model, social model, human rights model, and biopsychosocial model. Disability models aim to demonstrate how society perceives, understands, and addresses the needs of people with disabilities. 

The Disability Models 

Medical model: views disability as a personal tragedy in need of cure and rehabilitation.  

Social model: views disability as predominantly a socially driven issue; allows us to reconstruct social inequality for people with disabilities as a collective experience of discrimination and injustice, rather than a personal tragedy affecting only individuals. However, the model does not address the emotional aspects of disability and the realities of impairment.

Biopsychosocial model: views disability as a combination of an individual's state of health and their surrounding environment, that is, society. By recognising disability as a social construct of intricate variables and interaction of biological factors (genetic, biochemical, etc.) and psychological factors (mood, personality, behaviour, etc.), the social aspects (cultural, familial, socio-economic, and medical, etc.) is to recognise the complexity; specifically, the intersectionality that informs disability is recognised.

The human rights model: assumes that societal barriers can only be removed by guaranteeing rights to people with disabilities. Human rights principles recognise that fundamental rights are inherent in all human beings, regardless of race, gender, ability, and nationality. Therefore, disability rights are viewed as a human right under this paradigm, advocating for equal participation and opportunities for individuals with impairments. 

Promoting the human rights of people with disabilities, the White Paper on the Rights of Persons with Disabilities in South Africa mandates a universal design approach, which is defined as "the design of products, environments, programs, and services to be usable by all persons to the greatest extent possible without the need for adaptation or specialized design."

As per the Global Education Monitoring report on inclusion and education, the Universal Design for Learning (UDL) framework is particularly relevant for a comprehensive understanding of inclusive education as tackling barriers to learning, noting that "the Universal Design for Learning concept encompasses approaches to enhance accessibility and eliminate barriers to learning." Such an approach can help to integrate UDL into the educational system by addressing the various social, emotional, and learning requirements of different groups while working for the universal system-related goal.

South Africa is among the few countries in the world to have signed and ratified the most acclaimed global convention on disability in 2007. The international trend endorsed by the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) seeks to promote, protect, and ensure the full and equal enjoyment of all human rights by persons with disabilities. Although disability is varyingly defined, and definitions change across time and space, the UNCRPD defines persons with disabilities to include long-term physical, mental, intellectual, or sensory impairments, which in interaction with various barriers may hinder their full and effective participation in society on an equal basis. For this reason, creating and realising an inclusive upholding of the rights of persons with disabilities is critical in building an enabling environment for all. However, despite progressive legislative structures in South Africa, persons with disabilities continue to face barriers that prevent equal access to opportunities and participating fully in all aspects of life. It is primarily due to inaccessible infrastructure, prejudice, stigmatisation, discrimination, and attitudinal behaviour towards persons with disabilities, which often result from a lack of understanding.  

According to Stats SA, 80% of persons with disabilities aged 20-24 are not attending tertiary education, yet the population of students with disabilities at tertiary institutions is just 1%. It is also revealed that there is a strong demographic gap between races. Access to education is necessary for advancing sustainable development, but it is evident that inclusivity within tertiary education remains out of reach for many.  The University of the Free State aims to foster disability inclusion within the Integrated Transformation Plan, which is in line with the universal access approach guided by the Centre for Universal Access and Disability Support (CUADS). 

CUADS, a well-known disability unit, was established in line with non-discrimination legislative changes and inclusive policy frameworks for access and equal participation for students with disabilities. It serves as a bridge between students with disabilities and the institution, ensuring mutual understanding. The majority of such departments are led and managed by women, as women have a dynamic role in enhancing and nurturing the aspirations of children and youth with disabilities to get access to education. Despite the positive role of these departments in the full inclusion of students with disabilities, attitudinal barriers remain a challenge to their non-disabled counterparts. 

Furthermore, female students with disabilities face particularly higher levels of marginalisation and disadvantage because of the double discrimination based on their disability and gender. Their status as women renders them vulnerable to gender-based violence (GBV), including sexual abuse, maltreatment, exploitation, and intimate partner violence (IPV) compared to men with disabilities. 

South Africa has a high prevalence of GBV, especially IPV. Women with disabilities are more at risk and experience an additional layer of violence compared to women without disabilities and men with and without disabilities. It is also revealed that blind women and women with severe intellectual and mental disabilities are equally perceived as highly exposed to GBV compared to women with other disabilities (e.g., if an intellectually challenged individual could not give informed consent and/or when they report it, it will be difficult for them to identify the perpetrator). 

Furthermore, men with disabilities are at greater risk of GBV, but not comparable to women and girls with disabilities. The gap perpetuates unequal gender relations in all contexts of South Africans’ lives. While various organisations seek to promote women's rights in GBV advocacy, there is relatively little emphasis on GBV against persons with disabilities, including violence against women and children. 

To build an inclusive society, one needs to understand intersectionality concepts that provide a prism to comprehend marginalisation and exclusion better. Understanding intersectionality is related to how various identities such as race, gender, class, disability, sexuality, and others intersect – how lived identities are seen as entwined with oppressive systems that are mutually constitutive and reinforcing. Intersectionality as an approach recognises how complex reality is and how this complexity informs social conditions and behaviour; it acknowledges that people's lives are defined by multiple layered identities that derive from social relations, histories, cultures, and other operations of power structures. 
It is an analytical tool for exploring, comprehending, and responding to how gender intersects with different identities and how these intersections lead to distinctive oppression and privilege experiences. Also, intersectionality addresses how social structural norms such as racism, patriarchy, classism, and other social systems of discrimination function and interact to create social inequalities that shape attitudes and behaviour towards those who are different, such as those with disabilities. The approach invites us to shift away from binary thinking and towards a more global human rights stance.

Therefore, higher education institutions have a critical role in shaping the future of society as places where students are educated and prepared for their future vocations. In line with inclusive curricula, the university should introduce disability discourse into models such as UFSS, which is mandatory for all first-years. Also, the institution should increase awareness and visibility by incorporating critical disability messages into all discussions, addressing all aspects; utilising disability posters on campus, and departments such as Residence Life, KovsieSport, UFS Centre for Teaching and Learning (CTL), and CUADS should collaborate to host disability events and heighten communication around it; leveraging other mega events such as national days, themed days, conferences, etc., to spread messages on disability and to build an inclusive society; hosting lectures, debates, and discussions on disability topics and promoting rights of persons with disabilities; and hosting student competitions on equality, justice, and human dignity. Through such interventions, the university will have a community that can facilitate the creation of inclusive spaces in their homes, communities, work, and social areas. Disability should be a collective responsibility to achieve an inclusive society that upholds the rights of persons with disabilities. 

Inclusive legislative policies (i.e., the White Paper on the Rights of Persons with Disabilities, 2018 and the Strategic Policy Framework on Disability for the Post-School Education and Training sector) should guide institutions to ensure that students with disabilities are protected. These documents further promote the right to (inclusive) education, as a universal access approach in education does not benefit only students with disabilities, but everyone.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
