With completed membership forms in excess of 15 000 still to be collected, SADTU can talk of an effective membership of 50 000 teachers, the SADTU president, Shepherd Mdladlana said during his address to Congress at Nasrec, Johannesburg. The SADTU membership further consists of teachers from all departments all over the country, making SADTU the only unitary, non-racial teachers’ union in the country. In his report to Congress, SADTU General Secretary, Randall van den Heever, pointed out that the most progressive members of all erstwhile organisations - newly emergent as well as established - occupied leadership positions within the union’s branch and regional structures, making SADTU the most well represented union of teachers from all sectors.

- Description: The business sector has a substantial role in addressing current environmental issues and concerns. Consequently, there is a growing adoption of corporate sustainability principles and practices across all market sectors. This study examined four developed and four emerging stock markets and the sustainability reporting practices of the top 20 and bottom 20 companies in each. The results illustrate that the developed market sector was more advanced in its corporate sustainability reporting, both in the proportion of companies issuing a sustainability report (approximately 60 per cent) and the proportion of company webpages dedicated to sustainability reporting. This difference was largely due to the effect of the top 20 companies. There was little difference between developed and developing markets when only the bottom 20 companies were considered, of which less than one-third provided sustainability reports. These results show that sustainability reporting is prevalent in both developed and developing markets, especially among market leading companies, but that overall, most developing markets have some catching up to do.

Stripped of the hysteria, lies and inaccuracies, the central claim made is that Rhodes University is hostile to Jews and seeks to be rid of Jews. We reject with contempt these baseless and self-serving claims and allegations of the South African Jewish Report and Klazinga. Rhodes is committed to an institutional culture that respects and promotes equity, human dignity and human rights, embraces difference and diversity and is comfortable for all people irrespective of ‘race’, gender, language, culture, nationality, sexual orientation and religion. Rhodes welcomes all and will continue to strive to be a Home for All.

- Description: We studied the effects of mixed honeybee colonies of Apis mellifera and Apis cerana on the intraspecific and interspecific recognition of female brood stages in the honeybees A. cerana and A. mellifera by transferring brood combs between queenright colonies. In the intraspecific tests, significantly more larvae were removed in A. cerana than in A. mellifera, whilst significantly fewer eggs and pupae were removed in A. cerana than in A. mellifera. In the interspecific tests, A. cerana colonies removed significantly more larvae and pupae of A. mellifera than the same brood stages of A. cerana were removed by A. mellifera. We show there are highly significant differences in both intraspecific and interspecific brood recognition between A. cerana and A. mellifera and that brood recognition operates with decreasing intensity with increasing developmental age within species. This suggests that worker policing in egg removal is a first line of defense against heterospecific social parasites.

- Description: Model C Schools have created great controversy in recent educational policy debate. SADTU has joined the fray in opposition to the retention of these schools. Model C is a particular type of state aided school which is different to state aided schools like the farm schools that came under the authority of the former black Department of Education and Training (DET). The latter schools were mostly poorly resourced and inadequately staffed. Model C schools are state aided schools that have governing bodies elected by the parents, with power over a number of key functions of the school. These include control over admissions policy, the power to charge compulsory school fees and to raise funds by other means (e.g. renting out the school's property), the power to decide how the school's money is to be spent (e.g. school maintenance, the hiring of additional teachers and other staff, the buying of books and equipment, and the power to exercise influence over the hiring and disciplining of teachers). The system is unique among state- aided schools in that Model Cs are all former state schools in the privileged white school system. Nearly all inherited a sound infrastructure provided largely by the state in the form of school buildings, grounds, libraries, laboratories etc. They also inherited a well qualified teaching staff, whose training (the best in the country) was also partly the result of public subsidies. Model C has several strengths which has led to the ongoing controversy. Parental participation in the schooling of their children has been mobilised. The governing bodies actually have power over important aspects of the school in contrast to the old comparatively toothless management councils. This, it appears, has ensured that parents, whether they approve of Model C or not, take them much more seriously since the governing bodies can take decisions which materially affect them and their children's education. In addition, this model has mobilised private resources for education and ensured that a relatively high level of provision can be maintained while state funding is decreased. Money thus saved by the state - reportedly about R1 billion - can be diverted to redressing the inadequacies of African education.

The antibacterial activity of the medium polar extracts of T. potatoria leaves and stem bark was recently reported against Mycobacterium smegmatis (MIC 25 µg/mL) and M. aurum (65 µg/mL), two fast-growing Mycobacterium strains used as model micro-organisms for the more pathogenic strain Mycobacterium tuberculosis (Fomogne-Fodjo et al., 2014). The aim of this study was consequently to isolate the compounds possibly contributing to this activity, and which may therefore be promising precursors to be used for the development of novel anti-TB drugs.

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: Many heat shock proteins (HSPs) are essential to survival as a consequence of their role as molecular chaperones, and play a critical role in maintaining cellular proteostasis by integrating the fundamental processes of protein folding and degradation. HSPs are arguably among the most prominent classes of proteins that have been broadly linked to many human disorders, with changes in their expression profile and/or intracellular/extracellular location now being described as contributing to the pathogenesis of a number of different diseases. Although the concept was initially controversial, it is now widely accepted that HSPs have additional biological functions over and above their role in proteostasis (so-called ‘protein moonlighting’).

I will therefore focus on TGWU 's perspective on the current bus crisis future perspective and TGWU organisational role in the bus industry I felt it important to outline a brief background and our perspective cm the industry and how that dictates our attitude towards the industry. This paper is divided along the following sections;- Use of transport in internal economic and labour control. Contradictions and conflicts over transport policy. The future and its implications for Transport policy after apartheid. TGWU's organisational role and influence in the industry.

- Description: The objectives of this study were to prepare microcapsules containing verapamil and propranolol and to evaluate the kinetics and mechanism of drug release from the microcapsules using USP Apparatus 1. The effects of polymer concentration and polymer type on the cumulative amount of drug released were evaluated. The microcapsules were manufactured using Eudragit RS and RL polymers by solvent evaporation with the ultimate aim of prolonging drug release. Twenty-four formulations were prepared using different drug/polymer ratios. The effects of polymer type and polymer/drug ratios on the size, flow properties, surface morphology, and the release characteristics of the microcapsules were examined. The effects of drug inclusion methods on drug loading, encapsulation efficiency, and release properties of the complex microcapsules were also investigated. The formulations containing drug/polymer ratio 1:4 (w/w) were the most appropriate with respect to encapsulation efficiency (70%), flow properties (HR = 1.2), drug loading (15–20%), and drug release characteristics, in all cases. The release kinetics from the different formulations followed mainly a diffusion-controlled mechanism.

- Description: This short composition portfolio comprises 40% of the requirements for the Master of Music Degree in performance and composition at Rhodes University. In addition to the music presented here, I played two public exam recitals of 70 minutes each. While I played piano as a child, my main instrument during my BMUS studies at the University of Cape Town (2004-2007) was the saxophone. In 2010 I was diagnosed with Polymyositis(an auto-immune desease) which particularly affected my breathing and therefore my ability to play the saxophone. For this reason I opted to play my recitals on the piano. The first recital focused on interpretations of Swing Era, Bebop and post-Bebop standards such as: Someday my prince will come, What is this thing called love, In your own sweet way, Eternal Triangle, Recordame, Peace, Dolphin Dance, Caravan and Some other blues. The second recital comprised of seven original compositions that were presented in trio, quartet and quintet settings.

Then we achieved the victory that we had fought so hard for - a non-racial government that is democratic and transparent. But on the shopfloor we still see apartheid: racial inequalities - high wage differences between workers and management, poorly trained workers (mostly black and our members) racist management who oppress our members, badly managed factories with S old machinery. All these are obstacles that prevent us building worker power, worker control and a better life for all. Read what we have won. Discuss what we should campaign around in 1995.
