African wages in Grahamstown

  • Authors: SAIRR
  • Date: Sept 1974
  • Subjects: SAIRR
  • Language: English
  • Type: text
  • Identifier: http://hdl.handle.net/10962/148563 , vital:38750
  • Description: This survey was carried out in November 1973. My grateful thanks are due to the Grahamstown officials of the Cape Midlands Bantu Administration Board for permission to use the records of the Labour Office, and for the assistance given me during the survey. In particular I should like to thank the Area Manager, Mr. Bush, Mr. Freeman, the Manager, Mr. Hall, the Labour Officer, and the Clerks in the Labour Office who gave their help when needed. The aim of the survey was to provide up-to-date information on the basic rates being paid to African employees registered at the Labour Office in Grahamstown. The survey was intended to provide an overall view of wages paid in Grahamstown by various groups of employers, and to give some information on differing wage rates for males and females, and for Africans recruited in Grahamstown and working in other centres.

Ligand substitution effects in uranyl ο-hydroxyarylcarbonyl complexes

  • Authors: Haigh, John M
  • Date: 1974
  • Language: English
  • Type: text , Article
  • Identifier: vital:6372 , http://hdl.handle.net/10962/d1006075
  • Description: Twenty-two base adducts of uranyl o-hydroxyarylcarbonyl complexes [UO2L2B] (L = o-hydroxyarylcarbonyl compound, B = H2O, pyridine, pyridine N-oxide) have been prepared. Pure field substituent parameters are used to derive a quantitative order of the electronic effects of the chelate ring substituents. Values of v(U=O) correlate well with these values. Evidence is cited suggesting almost complete non-aromaticity of the chelate ring, and the transmission of the electronic effects of the chelate ring substituent through the uranium atom in the pyridine and pyridine N-oxide base adducts.

The fish Elops machnata in South Africa

  • 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: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 10 , A new genus is erected for Apogon maximus, a deep water cardinal fish occurring off the coast of southern Arabia in the Indian Ocean. Holapogon is a primitive genus near the ancestor which gave rise to all the living Apogoninae. The type-species, Apogon maximus Boulenger, 1887, is redescribed and aspects of its anatomy are investigated.
