African Experience

Membrane processes have recently been applied much more extensively by South African industry. A number of the older plants have suffered from fouling problems, sometimes brought on by changes in the feed stream. Newer installations are tending to apply the techniques of Cleaner Production to more closely integrate the membrane process into the manufacturing process and to reduce the size of the installation. There has been a trend to investigate methods of using the brine in place of discharging it to the environment. Membrane related research is still very active and a range of current initiatives is provided.

Depth Interviews

In this study we draw on a series of in-depth interviews with chief executives of some of South Africa’s most prominent businesses, to investigate how their careers unfolded as they rose to the top of their organisations.Twenty-seven CEOs of South Africa’s top companies were interviewed. Eleven of these companies are listed among the top 50 South African companies.We trace the evolution of leadership, from its embryonic beginnings in childhood and adolescence, through the different stages of a developing career to the crucial transformation of an operational mindset into a strategic one.We examine the circumstances that led to these CEOs being appointed and describe the difficulties of transitioning from a senior management role into that of chief executive. We look at the competencies and experience necessary to be effective as the leader of an organisation, as well as the role played by motivation and self-belief. Finally, we identify the unique leadership challenges faced by chief executives in South Africa and pass on their advice to the country’s next generation of leaders.

Public health and safety concerns have traditionally been the main reasons for resisting waste water reuse for fish farming. Potential adverse health effects in such applications could be avoided if the waste is sufficiently treated before reuse. In a full scale demonstration study in Suez, Egypt, about 400 m3/d of raw sewage were treated using a multi-compartment stabilization pond system, for a total residence time from 21-26 days. The treated effluent conformed to WHO guidelines and was used for rearing two types of local fish (tilapia and gray mullet). The produced fish were subjected to an extensive monitoring program. Bacteriological examination revealed that in all samples the fish muscles were free of bacterial contaminants. Nevertheless, low levels of Escherichia coli andAeromonas hydrophila, were isolated from the surface of the fish. Salmonellae, shigellae and staphylococcus aureus were absent from the surface of all the fish sampled. In addition, toxic metals (Pb, Cu, Zn, and Cd) were found to be at much lower levels than the international advisory limits for human consumption. It is concluded that fish reared in the treated effluent at Suez Experimental Station is (a) suitable for marketing for human consumption, and (b) it's quality is equal or better than fresh water fish in Egypt.

The One

Reconciliation emphasizes relationships as a crucial ingredient of political transition; this book argues for the importance of such a relational focus in crafting sustainable political transitions. Section I focuses on South Africa’s transition to democracy—how Mandela and De Klerk persuaded skeptical constituencies to commit to political reconciliation, how this proposal gained momentum, and how well the transition resulted in the goal of an inclusive and fair society. In developing a coherent theory of reconciliation to address questions such as these, I explain political reconciliation from three angles and thereby build a concept of reconciliation that corresponds largely with the South African experience. In Section II, these questions lead the discussion beyond South Africa into some of the prominent theoretical approaches to reconciliation in recent times. I develop typologies for three different reconciliation theories: forgiveness, agonism, and social restoration. I conclude in Section III that relationships created through political reconciliation, between leaders as well as between ordinary citizens, are illuminated when understood as an expression of a comprehensive “interdependence” that precedes any formal peace processes between enemies. I argue that linking reconciliation with the acknowledgment of interdependence emphasizes that there is no real alternative to reconciliation if the motivation is the long-term well-being of one’s own community. Without ensuring the conditions in which an enemy can flourish, one’s own community is unlikely to prosper sustainably. This theoretical approach locates the deepest motivation for reconciliation in choosing mutual well-being above the one-sided fight for exclusive survival at the other’s cost.
