  • Description: State control over the labour market usually results in the creation of different categories of labour, each having partial and unequal access to that market. In the Third World, typically, justification for control arises from an over-supply of unskilled rural labour and a small demand for such labour in the wage economy. To reduce massive urban unemployment, the state attempts to control the process of rural-urban migration by, inter alia, manipulating the labour market. ^ In South Africa, the civilised labour policy of the Pact government and the highly sophisticated system of black influx control introduced after the Second World War are two examples of such state control. In these cases, racial categories of labour, having differential access to the labour market, were created. The policy of Coloured Labour Preference is another South African example which is of particular interest since it is applied solely to one region of the Republic. Since 1962, when it was administratively coordinated for the first time, this policy has been applied in the Western Cape, a region comprising the 68 magisterial districts situated south-west of Port Elizabeth, Kimberley and the Orange River. In this region, black work-seekers' access to the labour market is severely curtailed. A series of regulations, particular to the Western Cape, are applied with the object of restricting the number of blacks resident in the region; denying blacks permanent rights of sojourn in the region; restricting the scope of employment for blacks in the region; and favouring coloured above black work-seekers throughout the region. In short, the policy aims to replace black by coloured labour and thereby aims to reduce to a minimum the number of blacks in the region. , Digitised by Rhodes University Library on behalf of the Institute of Social and Economic Research (ISER)

  • Description: "Change is not made without inconvenience, even from worse to better". I propose to examine a few of these “inconveniences", some of which may turn out not to be inconvenient at all, while others may mean a complete revision of life style, or abandonment of a cherished ideal. In either case, a most vital issue surrounding change is a quantity well known to scientists and engineers, austronauts and motorists, the quantity known as the rate of change, or alternatively, the acceleration or deceleration. Change comes fastest when great pressures or forces are exerted, either revolutionary forces which are aimed at causing events to move rapidly, or oppositely, when the forces of authority are exerted to prevent matters from developing at all. These latter cause a deceleration of the movement of events, but both conditions represent high rates of change with the concomitant dangers that flow from the existence of inertia in the system and the people. Inertia in the accelerating condition results in the movement passing beyond control. Inertia in the decelerating condition entrenches those who are opposed to change and blocks all the natural outlets through which internal pressure could be relieved. Communication demands as a prerequisite, education, so that the essential link in the control chain lies in the schools and universities, and particularly in the universities. If the feedback is to come into play, then the universities must be the places where people learn to process the information. Universities are also the places where real change could originate as history has shown, so that either way, their role is vital. Paradoxically, although universities have, on the face of it, changed vastly over the centuries, and particularly during this half century, yet they have, by and large, retained their democratic character more successfully than any other institution. As 1 see it therefore, the universities should be and could be, very deeply involved in societal change,

Characterization and mode of action of a bacteriocin produced by a Bacteroides Fragilis strain

  • Description: Bacteroides fragilis strain Bf-1 produces an extracellular bacteriocin at the beginning of the stationary growth phase. Production is not inducible by either ultraviolet light or mitomycin C. The low molecular weight bacteriocin (MW estimates of 13 500 and 18 800 obtained from Sephadex G-100 chromatography and SDS-PAGE electrophoresis respecively) is stable between pH 7 - 9 and is inactivated on incubation with trypsin and pronase. An unusual feature of the Bf-1 bacteriocin is its apparent biphasic temperature stability: while the majority of the activity (97%) is destroyed by heating at 60ºC (t [subscript] 1/2 = 2.5 min at 60ºC), a small proportion (3%) is stable even after autoclaving at 121ºC for 15 min. The killing of sensitive cells occurs in 2 stages and the killing action is reversed by incubation with trypsin. The transition from stage I to stage II is dependent on the temperature of incubation and the growth state of sensitive cells. 2,4-Dinitrophenol prevents this transition. The Bf-1 bacteriocin has an unusual mode of action. It specifically inhibits RNA synthesis whilst having no effect on protein or DNA synthesis. No effect on intracellular ATP levels were observed. The heat-stable (3%) fraction had a similar biochemical effect. In vitro studies involving RNA polymerase indicated that the bacteriocin and the antibiotic rifampicin have similar effects on RNA synthesis. The bacteriocinogenic strain (Bf-1) is insensitive to its own bacteriocin both in vivo and in vitro, although this immunity is overcome in vitro by the addition of higher concentrations of the Bf-1 bacteriocin. The bacteriocinogenic strain (Bf-1) harbors a cryptic plasmid (or plasmids) which on a neutral sucrose gradient, sediments faster than the Col E1 marker plasmid DNA. Attempts to cure this strain of its bacteriocinogenic phenotype were unsuccessful.

Christian joy

  • Authors: Williams, Denis Ivor
  • Date: 1980
  • Subjects: Joy -- Religious aspects -- Christianity Christian life
  • Language: English
  • Type: Thesis , Doctoral , PhD
  • Identifier: vital:1212 , http://hdl.handle.net/10962/d1001541
  • Description: Christian joy is identified by linguistic and symbolic, experiential and psychological studies, and by a study of its opposite, sorrow. The final and most comprehensive approach is Biblical and theological. Here, through Judaism and Christianity, the genesis and fulfilment of Christian joy is examined, in life and the gifts of God, in hope, and in union with God. It is defined as "a gift of God's Holy Spirit as man becomes one with Christ in love." Five hypotheses are evaluated and confirmed: - 1. God is perfect joy, 2. God is the source and end of all Christian joy, 3. Jesus Christ is both the most joyful and the most sorrowful of men, 4. The Christian participates in the joy and sorrow of Jesus Christ, 5. Christian joy is eschatological in nature. The need is stressed for a fuller understanding and expression of Christian joy, which is seen as the complement of Christian love, and as a distinguishing characteristic of Christians, because of its primary intentional and ultimate satisfactory nature

  • Description: Co-trimoxazole, a combination of a 5-to-l ratio of Sulphamethoxazole (SMZ) and Trimethoprim (TMP) , is a highly effective, broad-spectrum antibacterial agent. Since its introduction in 1968, it has been extensively used in infections of the respiratory and urinary tracts. Co-trimoxazole was developed by the systematic investigation of a series of compounds whose mechanism of action was already known. As early as 1950 synergy between sulphonamides and 2,4-diaminopyrimidines was reported. This was to be expected as both groups of drugs exert their antibacterial activity by interfering with the same biochemical pathway in bacteria. TMP was chosen from among many 2,4-diaminopyrimidines tested because of its good antibacterial activity and low toxicity. SMZ was chosen from the sulphonamides available for combination with TMP because of similarity of their biological half-lives. The widespread use of the combination coupled with the fact that monitoring of the levels of all drugs in the body is becoming increasingly important has stimulated research into rapid and efficient methods for the analysis of TMP and SMZ in biological fluids. Another consequence of the immense popularity of the combination is the appearance on the market of several generic preparations of Co-trimoxazole. It is now generally recognized that drug products from different manufacturers which are chemically equivalent may not be therapeutically equivalent. This is due to the fact that the absorption rate and/or bioavailability (extent of absorption) of a poorly soluble drug may be markedly affected by its release rate from the product and by its subsequent dissolution rate in gastrointestinal fluids. Hence bioequivalence of these various products should be established
