The use of environmental management accounting (EMA) remains debated in South Africa and the literature reveals that EMA is still at an infancy stage in the emerging economies, including South Africa. Currently, there is limited existing research on environmental management accounting practices available for use by the hotel sector in South Africa. The overall aim of this study was to investigate and describe the use of the environmental management accounting tools by the hotel sector in the 3-5 star categories in KwaZulu-Natal. The research was an exploratory study and qualitative in nature using a single case study with embedded units approach. It is envisaged that study will bridge the gap that exists in South Africa as far as environmental management accounting is concerned and it will also make the provision of meaningful results for policy decision making by the relevant stakeholders in the hotel industry. Moreover, it established factors that drive and/or hinder the implementation of EMA tools that would control and manage environmental costs and their root causes

‘Following the money’ has become a popular strategy for many NGOs trying to change corporate and institutional practice. Individual shareholders, pension funds, banks, and other investors capitalize projects that cause ecological degradation or social injustice. Pressuring shareholders to divest, invest responsibly, or encourage executives to alter undesirable practices has become de rigueur for civil-society groups working for social change. Such strategies produce value or norm change, greater accountability, activist networks across national boundaries, and improvements in environmental management. Disinvestment helped bring down apartheid in South Africa. But how far can these ‘disciplining’ strategies go in terms of significantly ameliorating ecological destruction and violations of human rights? I explore this question using the case study of the campaign by Friends of the Earth against the operations of Freeport – McMoRan Copper and Gold Inc. in Irian Jaya (West Papua).

Parameters identification on structure subjected to moving load can be predicted by using the accurate and reliable data. The concepts of recurrent neural networks (RNNs) approach have been used in parameters (crack locations and severities) identifications in structure subjected to moving load in the present methodology. This methodology has incorporated the knowledge based Elman's recurrent neural networks (ERNNs) and Jordan's recurrent neural networks (JRNNs) jointly for the identification of parameters. This approach has been addressed as the inverse problem for predicting the locations and quantification of cracks in the structure in a supervised manner. The Levenberg-Marquardt's back propagation algorithm is implemented to train the proposed networks. To check the robustness of the present method, Numerical studies followed by Finite Element Analysis (FEA) and experimental verifications (Forward problems) are presented as a case study by considering a multi-cracked simply supported structure under a moving mass. The estimated crack locations and severities obtained from the proposed RNNs model converge well with those of FEA and experiments. From the demonstration of the case study, it concludes that the proposed analogy can identify and quantify the crack locations and severities effectively.

This paper addresses the fields of social and service design in development contexts, practice-based and constructive design research. A framework for social design for services will be explored through the survey of existing literature, specifically by drawing on eight doctoral theses that were produced by the World Design research group. The work of World Design researcher-designers was guided by a strong ethos of social and service design for development in marginalised communities. The paper also draws on a case study in Namibia and South Africa titled ‘My Dream World’. This case study presents a good example of how the social design for services framework functions in practice during experimentation and research in the field. The social design for services framework transfers the World Design group’s research results into practical action, providing a tool for the facilitation of design and research processes for sustainable development in marginal contexts.

Cyberphysical system design automation utilizing knowledge based engineering techniques with globally networked knowledge bases can tremendously improve the design process for emerging systems. Our goal is to develop a comprehensive architectural framework to improve the design process for cyberphysical systems (CPS) and implement a case study with Axiomatic Design Solutions Inc. to develop next generation toolsets utilizing knowledge-based engineering (KBE) systems adapted to multiple domains in the field of CPS design automation. The Cyberphysical System Design Automation Framework (CPSDAF) will be based on advances in CPS design theory based on current research and knowledge collected from global sources automatically via Semantic Web Services. A case study utilizing STEM students is discussed.

This article discusses and raises awareness about the socio-economic plight of indigenous musicians in South Africa. Through a qualitative case study of the Venda musician, Vho-Talelani Andries Ntshengedzeni Mamphodo, dubbed the “Father of mbila music,” the article highlights the fact that the welfare of Black South African artists, particularly indigenous musicians in South Africa, is generally a precarious affair. Their popularity, at the height of their careers, sometimes masks shocking details of exploitation, neglect, and the poverty they are subjected to, which are exposed only after they have died. Empirical data identifies this as a symptom of, among other things, cultural policy and arts management deficiencies in the promotion of indigenous music. The article aims to find ways to redress this unfortunate situation, which is partially a product of general apathy and scant regard that these artists have perennially been subjected to, even by their own governments, as well as some members of their societies. All these factors mentioned are compounded by ignorance on the part of South African artists. Part of the objective of this study was to establish whether the exposition of the Vhavenda musicians is a typical example of all Black South African indigenous musicians and, if this is the case, whether the suggested ways to redress this unfortunate situation could contribute to or play a role in alleviating the plight of such artists in the entire country.

The migration of Zimbabweans into South Africa is shaped by several factors and processes. Traditionally, the decision to migrate was mostly based on family considerations (where gender stereotypic roles were a priority), although in some cases the migrants exercised individualism and personal agency. This led to migration trends that were male dominated. Current Zimbabwean migration trends reflect large volumes of women as the socio-economic crisis forces them to leave their country. These migrant women encounter a myriad of challenges in their host countries. This paper explores Zimbabwean women’s migration to the town of Mthatha in South Africa, highlighting their challenges and the strategies they employ to overcome these, as found in a recent case study. Applying a qualitative research design and using questionnaires and interviews to gather data from the 100 purposively sampled women, the study found that many Zimbabwean migrant women in Mthatha encountered numerous challenges. They lacked the required documents to live and work in South Africa, experienced exploitation and marriage constraints, and had broken ties with their families back in Zimbabwe. According to the study, these women managed to navigate these challenges, rising above the stereotypic norms and values that used to label them as non-productive citizens to superheroes who were supporting their families and the country’s economy—thus breaking the shackles of gender stereotyping to create new norms. These findings underline the importance of shifting from the traditional approaches to women migration and pursuing perspectives that present migration as a critical component of the process of social change and development to all migrants.
