Description: The Third Biennial Congress of the South African Democratic Teachers Union (Sadtu) is one of the most important national events in the short but eventful history of this giant teacher union. This Congress takes place against the backround of unprecedented political transformation which was ushered in by the dawn of a new democracy in April 1994. History will proudly record Sadtu as one of those pioneering allies who fought resiliently to liberate the masses of our people and to eradicate Apartheid education and all its vestiges. This Congress, scheduled to be convened during the period 11-13 July 1995, will be graced by the presence of more that 700 accredited Sadtu delegates, 100 national observers and 20 international guests. This, in fact, will be the largest assembly of delegates at a Sadtu Congress since inception. Since its inception in 1990 Sadtu has been steadfast and persistent in its resolve to transform the education system in our country. The early 1990’s were an era of heightened levels of teacher consciousness which highlighted the plight of the South African teacher. It was during this period and thereafter that thousands of teachers swelled the ranks of Sadtu as it was viewed as a champion of teacher rights and an ideal vehicle for transformative changes as espoused by the teacher at the grassroots level. This significant shift of membership from established teacher associations disturbed the balance of power in the education terrain. In grasping the strategic initiative Sadtu was able to earn an enviable position in educational struggles.

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.

Description: Eucalyptus grandis is a medicinal plant which has been indicated by Zulu traditional healer in the treatment of respira- tory tract infections, bronchial infections, asthma and cough. The investigation of the essential oil of this plant could help to verify the rationale behind the use of the plant as a cure for these illnesses. Essential oil was hydro-distilled from the fresh leaves and characterised for the chemical constituents and bioactivity. The main constituents of the oil of the E. grandis are α-Pinene (29.69%), p-Cymene (19.89%), 1,8-cineole (12.80%), α-Terpineol (6.48%), Borneol (3.48%) and D-Limonene (3.14%). The essential oil of E. grandis showed high scavenging of DPPH and ABTS radicals, and was active against 13 of the 16 organisms tested with the MIC ranging from 0.625 mg - 5.0 mg/ml; the MBC value ranged from 2.5 mg - 10 mg/ml. The essential oil also inhibited the growth of 7 of the 8 antibiotic resistant bacteria tested, with MIC ranging from 5 mg/ml - 10 mg/ml. The DNA extracted from the affected microorganisms did not show any dam- age however, there was an increase of released cytosolic LDH activity. We conclude that the antibacterial activity of the essential oil was exhibited through cell membrane damage rather than the damage of the DNA. It is apparent that the bioactivity of the essential oil of E. grandis plays an important role in the plants’ use in folk medicine for the treatment of respiratory tract illnesses.

Description: The second phase, the 'development phase' (January to December 2003), of an ongoing research project on policy implementation with specific reference to Grade 9 of the Human and Social Sciences (HSS) learning area of C2005 is described. More specifically, a journey, in which nine History and Geography teachers at two independent schools and one university lecturer, working collaboratively as an HSS research team, navigated their way through the national curriculum and assessment policy arena, pushed the boundaries of their own practice as reflexive practitioners, and implemented the first national application of the new General Education and Training Certificate (GETC), is outlined. The article consists of three sections. The first outlines and offers critical commentary on the national policy context in which the research was located, and in which all South African educators currently work. Drawing on national and international literature, it illuminates a number of issues pertinent to national policy enactment. The second section describes the Development Phase. It outlines two areas of curriculum innovation at the two schools, namely enquiry-based learning and the development of a learning process 'map', before honing in on Grade 9 CASS. Section three describes the implementation at the two schools of the HSS Common Tasks for Assessment (CTA) in October/November 2003. The conclusion synthesises the narrative.

Description: Accurate estimation of the levels of non-compliance to fishing regulations is crucial in ensuring that long term sustainability goals of fisheries are met. When requesting information regarding sensitive behaviour, such as an angler’s non-compliance to regulations through direct questioning methods (DQM), their responses can be influenced by social desirability bias (SDB). Literature in human dimensions research on methods for controlling this bias is limited. There has been an emerging prevalence in the use of the random response technique (RRT), which is a method aimed at reducing SDB in questions regarding sensitive behaviour, although it has never been validated against observed data in an environmental resource use context. An alternative to the RRT, the use of a ballot box method (BBM) has been successfully implemented to reduce SDB in contingent valuation studies and is introduced in this paper as a method for reducing SDB in face-to-face survey responses regarding sensitive behaviour.

Description: A new lycopsid, Kowieria alveoformis gen. et sp. nov., is described from the FamennianWitpoort Formation, Grahamstown, South Africa. It possesses spirally arranged elongated falcate vegetative leaves. Terminal bisporangiate strobili are present and show loosely grouped micro- and megasporophylls. Sporophylls are similar in shape to the vegetative leaves though somewhat wider with a marked expansion to house the sporangium. One sporangium is attached directly to the adaxial surface of the lamina. Each megasporangium contains up to four heavily ornamented hologulate megaspores of the Lagenicula type. The combination of both basal and derived characters within this plant places it at an interesting position at the base of the phylogenetic tree of rhizomorphic lycopsids.

Finding the optimum: fluoridation of potable water in South Africa

Description: Since the South African Department of Health has tabled legislation to make fluoridation of public water supplies mandatory, the issue of whether fluoride is beneficial or harmful has, once again, become controversial in South Africa. We reviewed the literature, the experiences of fluoridation in overseas countries and the latest WHO recommendations, and have found that fluoride is desirable at certain levels, and undesirable above these. The following recommendations are made for optimum fluoride levels in South Africa's potable water: The decision to fluoridate a public water supply must be a community decision taken after public consultation. However, it can only be reached when the public is properly informed about the issue. Optimum levels of fluoride for human health range from 0.4 to 0.7 mg F/l, depending on the maximum mean annual temperature. The maximum level of 0.7 mg F/l should not be exceeded. Accordingly, it is recommended that in areas where natural fluoride concentrations in the drinking water exceed 0.7 mg F/l steps be taken to defluoridate the water. As an interim measure, a scale of temperature-adjusted optimum fluoride levels should be adopted in South Africa, rather than a single level covering the wide-ranging ambient temperatures (and corresponding consumption rates of drinking water) in the country. A sliding scale would mean that the community within a water supply region can determine its own fluoride consumption within the optimum range. Fluoridation should be considered only a short-term measure, until economic conditions are such that all South Africans have access to proper dental health care. The duration of fluoridation of a community water supply, and the level of fluoridation (within the optimum range of fluoride levels) should both be considered community decision. However, defluoridation should be a permanent necessity in those areas where the drinking water exceeds levels of 0.7 mg F/l.

Description: Octopus vulgaris was identified as a new marine resource to be commercially exploited through an experimental fishery. A recent policy on developing fisheries in South Africa emphasizes the importance of investigating the economic feasibility of a fishery as part of its management framework. The study reported here generated baseline information necessary in the design of the experimental fishery, giving guidelines as to which vessels, fishing gear and markets would be most feasible. The proposed fishery, gear and vessel type, fishing techniques and expected catch rates are described, the results of market research are outlined, and the cost of fishing is estimated. The potential business should consist of small and medium-sized vessels deploying unbaited pots attached to long lines. The longline pot fishery could be economically feasible, provided a 30 percent catch in 6600 pots/month is attained. Only existing, debt-free vessels should be used. The minimum catch per unit effort (CPUE) for various fishing operation scenarios was calculated to determine economic feasibility. This is an estimated minimum CPUE, based on assumptions that cannot be confirmed until the fishery starts. Furthermore, this economic analysis also needs to be assessed by stakeholders with experience of fishery operations , Rhodes Centenary issue of: South African Journal of Science.

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

Description: At the time of independence, most African countries were poised to take charge of their own affairs. However, postcolonial realities characterized by political upheavals, coups and counter-coups, civil wars, and economic downturn, among other setbacks, created a sense of ambivalence in terms of political and economic freedom. In Nigeria, satirical expressions became the tool used against oppressive regimes. In post-independence Nigeria, from the military dictatorial era to the present civilian dispensations,1 sociopolitical issues have been lampooned in different forms of expression such as music, performance, cartoons, and memes. Within this environment, political cartoons began to thrive, as they became a relatively safe way to comment on the political issues of the day (Akande 2002: 2). This was achieved largely by concealing the main subject matter behind the “masks” of metaphoric imagery, which enabled cartoonists to develop narratives that counter the dominant narratives, often opposing governmental policies and practices.
