- Description: The aim of the government' s state of emergency in June 1986 was to try and bring the country under control through the use of force. Tens of thousands of people were detained, and many were tilled. At the same time, the government has been building a National Security Management System (NSMS). This is a series of structures throughout South Africa, designed to defend apartheid. The main type of structure is called a Joint Management Centre (JHC). Before we explain what a JMC is and what it does, it is useful to know where the idea for a National Security Management System comes from.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: The Rivonia treason trial started on October 9, 1963, the same day that former Cape Town coloured singer Danny Williams made front page headlines by marrying a white girl in London. Those were the days when apartheid, not as “reformed” as it is today, was rigorously applied by the National Party government. Love, sex and marriage across the colour line were forbidden. Crooner Williams, 31, then riding the crest of the pop wave with his ballad “Moon River”, took his vows with Bobbi Carole, who married him against the wishes of her parents. Williams, fearing persecution, told an interviewer he would not be welcome in South Africa again. But most prominent by far on the front page that day was the Rivonia treason trial. A report from Pretoria — following the style of the times — said: “Eleven men — four whites, one Indian and six Natives — went on trial in the Supreme Court here today before Mr Justice Quartus de Wet (Judge President of the Transvaal) on charges of sabotage and of offences under the Suppression of Communism Act and of contravening the Criminal Law Amendment Act.” , Supplement to The Argus, Wednesday February 7 1990 , Exclusive Part 2

Staff writer DENNIS CRUYWAGEN travelled extensively to interview at first hand — or by other means, where necessary — those stalwart ANC veterans who were convicted in the Rivonia Treason Trial and jailed with Mandela. He talked, too, to members of the Mandela family, politicians, lawyers and many others who were close to or knowledgeable about the ANC leader. Official records and other sources on the life and times of Nelson Mandela were also consulted. Compiling the vast amount of information sometimes led to unusual situations. For instance, Mrs Winnie Mandela, always pressed for time, was interviewed — not in her home in Diepkloof, Soweto, as arranged but in a hired car in a Johannesburg traffic jam while following a vehicle driven by her driver. She was late for another appointment. Drawn from various sources this series sets out to reconstruct an overview of 25 years and more of political and personal drama, passion and poignancy. , Supplement to The Argus, Tuesday February 6 1990 , Exclusive Part 1

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 11 , Introduction: The status of the species of Elops present in the Indian Ocean along the southern part of Africa has been uncertain in recent times. Two names have been applied - Elops saurus Linnaeus, 1766 and Elops machnata (Forsskål, 1775) by numerous workers up to the present despite three revisions of Elops concluding that only one species, E. machnata, occurs in the western Indian Ocean (Regan, 1909; Bertin, 1944; Whitehead, 1962). These workers also demonstrated that Elops saurus is fotmd only in the western Atlantic Ocean and can be separated 100% of the time from E. machnata by vertebral counts (73-82 in E. saurus and 60-66 in E. machnata). Why, then, have workers persisted in using both names but not exclusively one or the other? There appear to be two reasons: 1. Some workers regard Elops to consist of one world-wide tropical species (in which case E. saurus is the oldest valid name). 2. The inadequate material upon which Regan, Bertin and Whitehead based their conclusions about the species of Elops. The first idea does not appear to be tenable with the evidence presented in the three species revisions and I regard it as erroneous. The second reason is real. We lack the basic information on geographic variation, if any, for the Indian Ocean population. Regan (1909) examined two specimens, Bertin (1944) an unknown number and Whitehead (1962) seven specimens. Whitehead (1965:231) indicates some doubt about the South African population and its status relative to the West African species E. senegalensis Regan, 1909. Furthermore, both Whitehead (1965) and Losse (1968) suggest that E. machnata and E. hawaiensis Regan, 1909 possibly may be subspecies of the same species, but indicate present data to be inadequate. This paper documents meristic and morphometric variation of 39 Elops mostly taken in South African estuaries as a first step toward understanding variation of the southern-most population in the Indian Ocean. South of Durban, South Africa, Elops machnata frequents the coastal waters only during the warmer months and is known to reach Mossel Bay. No species of Elops has been reported along the colder south western coast of southern Africa. The size range examined is large, 30 mm-900 mm SL (or to 6,9 kg), but does not include the maximum recorded size in South Africa of 13,7 kg. Losse's (1968) data for central East Africa are of nearly comparable size range and provide a useful comparison.

Regan (1909) examined two specimens, Bertin (1944) an unknown number and Whitehead (1962) seven specimens. Whitehead (1965:231) indicates some doubt about the South African population and its status relative to the West African species E. senegalensis Regan, 1909. Furthermore, both Whitehead (1965) and Losse (1968) suggest that E. machnata and E. hawaiensis Regan, 1909 possibly may be subspecies of the same species, but indicate present data to be inadequate. This paper documents meristic and morphometric variation of 39 Elops mostly taken in South African estuaries as a first step toward understanding variation of the southern-most population in the Indian Ocean. South of Durban, South Africa, Elops machnata frequents the coastal waters only during the warmer months and is known to reach Mossel Bay. No species of Elops has been reported along the colder south western coast of southern Africa. The size range examined is large, 30 mm-900 mm SL (or to 6,9 kg), but does not include the maximum recorded size in South Africa of 13,7 kg. Losse's (1968) data for central East Africa are of nearly comparable size range and provide a useful comparison.
