- Description: Traditionally, health records have been stored in paper folders at the physician’s consulting rooms – or at the patient’s home. Some people stored the health records of their family members, so as to keep a running history of all the medical procedures they went through, and what medications they were given by different physicians at different stages of their lives. Technology has introduced better and safer ways of storing these records, namely, through the use of Personal Health Records (PHRs). With time, different types of PHRs have emerged, i.e. local, remote server-based, and hybrid PHRs. Web-based PHRs fall under the remote server-based PHRs; and recently, a new market in storing PHRs has emerged. Cloud computing has become a trend in storing PHRs in a more accessible and efficient manner. Despite its many benefits, cloud computing has many privacy and security concerns. As a result, the adoption rate of cloud services is not yet very high. A qualitative and exploratory research design approach was followed in this study, in order to reach the objective of proposing guidelines that could assist PHR providers in selecting a secure Cloud Service Provider (CSP) to store their customers’ health data. The research methods that were used include a literature review, systematic literature review, qualitative content analysis, reasoning, argumentation and elite interviews. A systematic literature review and qualitative content analysis were conducted to examine those risks in the cloud environment that could have a negative impact on the secure storing of PHRs. PHRs must satisfy certain dimensions, in order for them to be meaningful for use. While these were highlighted in the research, it also emerged that certain risks affect the PHR dimensions directly, thus threatening the meaningfulness and usability of cloud-based PHRs. The literature review revealed that specific control measures can be adopted to mitigate the identified risks. These control measures form part of the material used in this study to identify the guidelines for secure cloud-based PHRs. The guidelines were formulated through the use of reasoning and argumentation. After the guidelines were formulated, elite interviews were conducted, in order to validate and finalize the main research output: i.e. guidelines. The results of this study may alert PHR providers to the risks that exist in the cloud environment; so that they can make informed decisions when choosing a CSP for storing their customers’ health data.

The use of photography as a vehicle for socio-cultural commentary on the stigmatisation of albinism in sub-Saharan Africa

- Description: This study provides an investigation into the current transition socio-culturally concerned photographers are making from traditional two-dimensional flat imagery, towards three-dimensional materiality based photographic installation artworks. According to Dr. Gillian Rose (2016), larger society is found to be in a state of oculacentrism, where vision and visuals are central to contemporary every day experience, resulting in the medium of photographic expression not being used and experienced by the average person as an art medium at all. So much so that these traditional photographic forms of visual communications have found a decline in visual engagement and subsequently visual impact. In an attempt to combat this change in the relationship between photographic imagery and audiences, select socio-cultural photographers are adopting practices incorporating three-dimensional, immersive installation techniques (Shore, 2014: 7-11), (Lister, 2007: 272). The aim is to provide a three-dimensional installation space, where the audience is encouraged to engage with socio-cultural issues. The study focuses specifically on two sociocultural photographers, Damien Schumann and Angelica Dass, who have communicated socio-cultural stories in this three-dimensional photographic installation space. In order to analyse and derive valuable techniques and approaches from their selected works The Shack (2010) and Humanae (2017) the study combines sections of Dr. Gillian Rose’s Visual Methodologies Framework (2016) as well as installation analysis tools designed by author Mark Rosenthal (2003). The same analytical criteria are then applied to the practical components socio-cultural topic communicating the Stigmatism Towards Persons With Albinism in Sub-Saharan Africa. The study concludes having created a three-dimensional photographic installation exhibition using similar techniques identified within the selected artists, moving beyond twodimensional forms to present a combination of three-dimensional techniques for enhanced socio-cultural visual communications.

- Description: Craftsmanship in contemporary art production is the main area of focus for this visual arts based research. An exploration into the artistic production processes of selected contemporary artists’ work, reveals a tendency of physical non-involvement on the part of the artist, who takes up the role of art director. The research enquiry attempts to provide an answer as to whether credit should be given to the craftsman as well as to the artist in this artist/craftsman relationship. The use of a practice-led research strategy allows the researcher’s art-making practice to become an integral part of the cycles of research, as the development of the researcher’s practical understanding, techniques and execution are crucial in the practical component, but also conceptually as a stance in opposition to the selected artists’ lack of practical involvement. The researcher has identified and analysed the following five factors that have contributed to this current state of art production in contemporary art: Kitsch as an influence on the subject matter and content of art, Marcel Duchamp and his idea of the ‘readymade’ and issues of authorship, Andy Warhol and his ideas on art and business, the Conceptual Art movement and, the act and product of craft being perceived as being inferior to the fine arts In addition, an exploration of the production processes involved in the creation of the artworks of Jeff Koons, Damien Hirst, Maurizio Cattelan and Takashi Murakami highlights the craftspeople, fabricators and foundries that are responsible for these artists’ highly crafted aesthetics. As practice is crucial in developing a new understanding and meaning in visual-arts based research, the practical component describes the researcher’s core practical themes as being the following:the creation of naturalistic figurative small-scale sculptures in resin and bronze, placing the characters explored in the theoretical component as the subject matter.The advantages and disadvantages of the collaborative experience with Sculpture Casting Services (fine art foundry) and eNtsa (a Technology Innovation agency), especially the implementation of 3D technologies in both experiences; and the technical development and understanding in order to improve the researcher’s artistic practice Collaboration is an important underlying theme throughout this research undertaking. It is crucial in the production of most contemporary art, and assists in identifying the artist’s role within the production of his/her work. Finally, it relates to the researcher’s collaborative experience expanded upon in the practical component and its benefits as a production method. In concluding, the researcher finds that craftspeople do receive credit for the work they do in the form of money, business and marketing. They provide a service that a great number of artists generously support. Foundries and fabricators also place a mark on the work they do, much like the artist’s signature, as a symbol of pride and recognition. It is ultimately the artist’s technical abilities, workload and artist identity or brand that will determine the extent to which he or she will contribute to the collaboration, whether that be a simple idea, a sketch, a maquette or a large-scale sculpture ready for installation. However, in a rapidly advancing technological society, it is the idea of the artist as craftsman, both thinker and maker, that demands more respect.
