An additional language, sign language was approved as an official language at the end of 2008. The Constitution of the Republic of South Africa and the South African Schools Act 84 of 1996 emphasise teaching and learning through any mother tongue, a learner would understand best. Section 29(1) of the Constitution of the Republic of South Africa categorically states that: "Everyone has the right to receive education in the official language or languages of their choice in public educational institutions where that education is reasonably practicable". However, most text books written in English have been prescribed at many schools. One is not certain whether the subjects are taught in English or in the indigenous language at these schools. In the end, those teachers use the mother tongue, together with English, in teaching learners. This result in code switching and code mixing takes place in classes, which are meant to facilitate communication across barriers of colour, language, and region, while creating an environment in which respect for languages other than one's own would be encouraged. Teaching and learning in one's mother tongue promotes full participation in the economy of the country. The aim of the paper is to investigate teaching and learning in Vhembe primary schools of the Limpopo Province in South Africa, within the framework of existing legislation. This will be compared with empirical evidence. The researcher seeks to establish what language(s) primary schools use for teaching and learning. Based on this, conclusions and recommendations will be made to assist stakeholders in language-in-education policy formulation.展开更多

It informs that there are original principles apprising what is commonly referred to as Batho Pele principles. The original principles are principles about Batho Pele principles. Batho Pele principles are not Bantu principles due to the historical and derogatory orientation of the phrase "Bantu". They are people orientated principles. The analytical axis is premised on that Batho Pele principles are more about the people than about themselves. The people are not only first in relation with the principles but are the first to be first before the principles were documented. The principles are developed by the people in order to regularize the actions of the public functionaries. The Batho Pele principles and the original principles do not exist in isolation. They are deeply rooted in the societal value systems of the people that existed from one generation to the other to the subsequent, emphasizing the centrality of people in relation to principles. The people's centrality is accentuated with references to a reasonable number of specific people orientated instruments that have bearing in the global and international arena.展开更多

While these debates were once politically germane, recent trends show a decline of donor funding, as well as an increase of financial ownership of the epidemic within Southern Africa. Commensurate with this shifting financial influence, some well-governed, wealthy African states are beginning to deviate from global M&E (monitoring and evaluation) indicators. These policy movements, away from global M&E indicators, also correlate with increases in HIV prevalence, which signals the need for further investigation into policy efficacy.展开更多

This has been due in part to the member countries' inadequate electrical power supply system, as well as load growth in areas which were not adequately planned for. This has induced the formation of organizations such as SADC (Southern African Development Community) and SAPP (Southern African Power Pool) that have the common goal of achieving development and economic growth in the region which comprises of 15 member countries. This paper presents results from a security analysis of the region's electric power supply system using a baseline level of performance. This was carried out by performing a steady-state contingency analysis on a SADC power network model subject to the N-1 criteria which expresses the ability of the power network to experience a contingency without causing an overload or failure in any other part of the network. Simulations were carried out using DigSilent.展开更多
