Description: This study characterizes the assemblages of Hymenoptera that visit flowers of the genera Aspalathus Linnaeus, Lebeckia Thunberg, Wiborgia Thunberg and Rafnia Thunberg, the Cape Group of Crotalarieae (sensu Polhill1981) (Papilionaceae) , and evaluates the potential of their members as pollinators. All the assemblages from the western and eastern Cape are characterized by the presence of Megachilinae (Megachilidae) and Xylocopinae and/or Anthophorinae (Anthophoridae), and those from the west (excluding Rafnia) by the presence of Masarinae (Vespidae). Although not restricted to Polhill's Cape Group, the Megachilinae and Xylocopinae are potential pollinators. Two species of Masarina Richards (Masarinae) are apparently restricted to Aspalathus, Lebeckia and Wiborgia, and are potential pollinators of the smaller-flowered species of these genera. Two species of Ceramius Latreille (Masarinae) are apparently restricted to Aspalathus and are potential pollinators and, within their distribution ranges, the most dependable visitors of this genus. Apis mellifera Linnaeus (Apidae) and Eumeninae (Vespidae) visit all four genera but are probably of little importance as pollinators. Apis mellifera is certainly able to obtain nectar from the smaller-flowered species without tripping the flowers. The implications of these findings for seed production in the rooibos tea industry are discussed.

IEC CONFERENCE ON PROFIT SHARING

Description: At present, profit sharing does not fit into the philosophy of any trade unions in South Africa. It is not a part of the policy of any union I know about. Where profit sharing schemes exist and are accepted by the unions, this is because of special circumstances. This talk is in three parts: First, I will explain where my union, the National Union of Mineworkers, has accepted profit sharing schemes and why it has done so. Secondly, I will outline the different levels of agreements that we have negotiated on profit sharing and the principles we have agreed should govern such schemes Thirdly, I will speak of the implementation of the schemes, and their potential for providing a basis for greater worker participation in the enterprises which have negotiated profit sharing agreements.

Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 54 , After examination of Col. Tickell’s unpublished manuscript and colour paintings of Burmese fishes, Day (1888) listed the surgeonfish Acanthurus tristis Tickell as a synonym of A. tennentii Gunther (1861); he gave the dorsal-fin spine count of 8 and provided a colour description, including mention of a white margin on the caudal fin. Of the species of Acanthurus, only A. pyroferus Kittlitz from the Pacific has 8 dorsal spines. Randall (1956a) treated tristis as a synonym of this pecies; the differences in colouration between tristis and pyroferus were regarded as within the range of variability of the latter. Both forms were observed together in Bali in 1982-1991. A. tristis is therefore regarded as a valid species and is redescribed. In the interest of stability of nomenclature, a neotype for A. tristis is designated.

Description: This paper gives an overview of the approach used for the assessment of several operating systems for microcomputers. The operating systems are all commercial products and cover a spectrum ranging from general purpose operating systems to small, real-time operating systems. The criteria used for the evaluation are discussed and the approach used is discussed in detail. The results of the evaluation are not discussed in this paper.

Glasnost and glaciers, yurts and yaks : a scientist in Soviet Central Asia

Description: Why are glaciers retreating, and are all glaciers retreating? There is much evidence to suggest that, globally, mean annual air temperatures are rising. Yet not all areas of the world have experienced temperature increases. In 1989 a Joint UNESCO/IGCP research project, Project 297, was initiated in order to identify and correlate geocryological features in mountain areas. A visit to the Alpine Geocryology station of the Academy of Sciences of the USSR to study rock glaciers afforded the author a glimpse of Soviet Asian evidence of climatic change and caused him to revise his interpretation of rock glacier and other geocryological remains in the eastern Cape Drakensberg.

Description: Cox et al. (1967) first delineated the existence of two major geochemical provinces in the Karoo basalts of southern Africa. Tholeiitic basalts in Zimbabwe are highly enriched in incompatible trace elements and constitute the "northern province". In contrast, basalts from Lesotho and from the southern segment of the Lebombo monocline have lower or “normal” abundances of these elements and were regarded as a "southern province'. Recent work has established that this change in composition takes place relatively rapidly in the Central Lebombo.

Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 34 , Two new species of syngnathine (tail-pouch) pipefishes sharing a continuous median dorsal snout ridge, a short snout (its length more than 2 in HL), presence of lateral spines or ridges on the snout, dermal flaps on the eye, 14 trunk rings and ca. 21-23 dorsal-fin rays are described and illustrated. Halicampus zavorensis is distinguished by a linear and distally spinulose dorsal snout ridge, two lateral spines on the snout and 36-37 tail rings. In H. marquesensis, the arcuate and partly denticulate dorsal snout ridge is paralleled distally by a bilateral pair of ridges which originate on the interorbital, there is a vestigial lateral ridge on the snout, and there are 39-40 tail rings. These pipefishes are compared to other species presently referred to the genus Halicampus Kaup.

An introduction to the Federation of South African Trade Unions

Description: The formation of FOSATU is part of a long history of struggle to organise the Black workers of South Africa into independent, non-racial trade unions. Black worker resistance in South Africa is as old as the introduction of wage labour but the first effective recorded trade union organising black workers was started in 1917 to be followed by the more famous ICU (Industrial and Commercial Workers Union) in 1919. Ever since then unions have fought against State and employer hostility to the unionisation of black workers. Other federations rose and fell. The 1950's marked a great rise in political and worker organisation with the emergence of the South African Congress of Trade Unions (SACTU) as part of the Congress Alliance. Severe State repression led to the 1960's being a low point of worker organisation. However, growing economic problems of inflation, unemployment and poverty plus a very much larger industrial working class led to an upsurge of worker militancy in the early 1970's. This gave rise to new union organisation in Natal, Transvaal and Port Elizabeth. By 1974 new coordinating bodies had emerged in Natal and the Transvaal. The need for greater unity was clear in the face of hostility from the State, employers and established unions - both the racist white unions and those in the Trade Union Council of South Africa (TUCSA).

Description: The Federation of South African Trade Unions - FOSATU - was formed on the 14th and 15th April 1979 at an Inaugural Congress held at Hammanskraal, north of Pretoria. The Congress was attended by 130 delegates representating 12 founding unions. FOSATU was formed as a federation to unite all workers irrespective of race, creed or sex who shared the common objective of struggling for the rights of workers. Our prime objective is to organise workers in their workplace and through the strength of their organisation to eliminate the racial discrimination and racial divisions that are used to perpetuate the exploitation of the oppressed majority of workers. It is a federation of industrial unions bound by common policies and objectives and based on the closest possible cooperation to the mutual benefit of all its affiliates and their members.

Description: The activity of a 0.1% amcinonide cream was compared with those of selected proprietary topical corticosteroid formulations of potencies differing according to the United Kingdom (U.K.) MIMS classification (very potent, potent and moderately potent) using a standard six hour vasoconstrictor assay with multiple reading times. Statistical analysis indicated that 0.1% amcinonide cream feU within the category of a very potent preparation. Three 0.1% amcinonide formulations (cream, combination cream and combination ointment, the last two containing anti-infective agents) were equipotent in the skin-blanching test.
