Disruptive behaviour in the Foundation Phase of schooling
Since the passage of legislation banning corporal punishment in South African schools, disruptive behaviour in schools has become an issue of national concern. Against this background a research project was undertaken in which the types and causes of disruptive behaviour occurring most frequently in the Foundation Phase of schooling were identified, with a view to providing strategies for teachers to manage behaviour of this kind. A qualitative research approach was applied. Data collection was done by conducting interviews comprising semistructured questions with Foundation Phase teachers. Strategies purposely devised to deal specifically with the identified types and causes of disruptive behaviour are explained.Keywords: disciplinary procedures; discipline problems; disruptive behaviour;disruptive behaviour strategies; human dignity; misbehaviou
The Possibilities of applying present-day Knowledge of Wine Aroma Components: Influence of several Juice Factors on Fermentation rate and Ester Production during Fermentation
The influence of several juice factors on fermentation and ester production was investigated to achieve a more satisfactory reproducibility of wine aroma composition. The contents of two acetates and three ethyl esters in the winewere used as the main analytical criteria. The factors which exerted the most marked influence on ester composition and fermentation were grape maturity, sugar content, fermentation temperature, and jutc'e>cfarity. The cuitivars examined exerted no noticeable differences
A strategic study of the impact of invasive alien plants in the high rainfall catchments and riparian zones of South Africa on total surface water yield#
The aim of this study was to develop a methodology to determine the impact of upland (non-riparian) invasive alien plants in the high rainfall catchments and riparian areas in all catchments on the total surface water yield available in each of the water management areas of South Africa. This would enable the Department of Water Affairs and Forestry (DWAF) through its public programme Working for Water (WfW) to develop a user charge system for the clearing of invasive alien plants in South Africa. It was found that the total impact of upland invasive alien plants in the high rainfall catchments on the total surface water yield of the country, which included the yield from major dams, minor dams and run-of-river yield, was currently approximately 172 x 106 m3/a and could go up to as much as 1 410 x 106 m3/a in the future. The impact varied greatly between water management areas and had the potential to reach 50 % (195 x 106 m3/a) of registered water use in the Thukela WMA in the future if not controlled. The reduction in yield due to invasive alien plants in the riparian zone in all catchments was estimated to be approximately 523 x 106 m3/a under current conditions and this could increase to 1 314 x 106 m3/a if the riparian zone was allowed to become fully invaded. The combined impact was estimated at 4% of current registered water use and could increase to 16 % of registered water use in the future
Determinants for realisation of the right to food among adolescents in Sterkspruit, Eastern Cape Province, South Africa
Globally, the youth population aged between 10 and 24 years is the fastest growing and faces health and nutritional challenges affecting their growth and development, livelihoods and future careers. The government needs to take necessary action towards the full realisation of the right to health, water, education and adequate standards of living, amongst others. A cross-sectional descriptive study using a mixed method approach was conducted. The study aimed at gaining an insight into perceptions about underlying factors, having an impact on the realisation of the Right to Food (RtF) of adolescents in the Sterkspruit area of the Senqu sub-district (Eastern Cape Province). It, furthermore, explored possible solutions and opportunities to facilitate the progressive realisation of the RtF for adolescents in this area. In-depth interviews were held with eight (8) key informants who were actively involved in the community. Fifty (50) adolescents aged 10 to 19 years completed a self-administered questionnaire and participated in Focus Group Discussions, stratified for gender and age. Through content analysis of qualitative data, transcripts were coded and emerging themes were grouped, using the ATLAS.ti 7 text analysis programme. Sixteen (16) percent of the adolescents sometimes had access to only one food source at home and have experienced hunger at times. The most pressing issues identified by participants, which compromises the realisation of adolescents’ right to food and health, was hunger caused by a combination of a monotonous diet, lack of agrarian resources, unemployment and mismanagement of Child Support Grants. Although government was regarded as the main duty-bearer responsible for the realisation of the RtF, it was perceived to be inefficient in taking sustainable measures to enhance food security in this resource-poor area. Very few participants identified adolescents’ own responsibility as rights-holders. The implementation of a human rights-based approach is needed for both the dutybearers and rights-holders to facilitate adolescents’ physical and economic access to sufficient, safe and nutritious food
Ecorestore: Decision Support System to Restore the Productivity of Degraded Rangelands in Southern Africa
Land degradation is a multifaceted problem that affects the agricultural productivity of land due to a loss of vegetation cover and can often be ascribed to bush encroachment in savanna and grassland rangelands. Bush encroachment entails the increase in abundance and density of indigenous and alien woody vegetation (i.e. shrub thickening), which has a negative impact on the tree-grass ratio, biodiversity, as well as on a range of ecosystem services that affect the well-being of land users, often causing an increase in poverty and the introduction of non-sustainable land management practices, especially in arid- and semi-arid regions mostly affected by climate change. In response, the North-West University, in collaboration with the Natural Resource Management (NRM) programme of the South African Department of Environment, Forestry and Fisheries (DEFF) and consultants, developed the Bush Expert Information Management System (BEIMS) that will help land users to make scientifically sound decisions regarding the restoration/rehabilitation and sustainable management of degraded land. The core components of the BEIMS are the EcoRestore Decision Support System (DSS) that contains guidelines for restoration after bush control and the Bushmon database that contains information (including spatial location) of bush encroachment restoration research projects. The BEIMS (abbreviated as Bush Expert) is a cloud-based, easily accessible online system which can also be linked to a standalone Global Information System via a spatial database link. Stemming from the BEIMS, the EcoRestore DSS can provide scientifically assessed information on projects where restoration technologies have been applied – including aerial photography that track the before and after successes of restoration/rehabilitation processes. To follow is a discussion of the results of a number of restoration applications derived with the aid of BEIMS, with due consideration for the current functionality and accessibility of the system
Familial hypercholesterolaemia: the Cape Town experience
Familial hypercholesterolaemia (FH), an autosomal dominantly inherited disorder characterised by elevated plasma low-density lipoprotein (LDL) cholesterol levels, tendon xanthomata and premature ischaemic heart disease, is amenable to treatment with modern medication. The clinical and biochemical details of 1 031 patients with FH were analysed. FH is the most common monogenic disorder of lipoprotein metabolism presenting to the Lipid Clinic at Groote Schuur Hospital, accounting for about 20% of consultations. The hospital classified 55% of the FH patients as white, 43% as coloured, 1.5% as Asian and 0.5% as black. In the FH cohort (whose mean age at presentation was 44 years), 80% had tendon xanthomata, 36% had arcus cornealis, and 14% had xanthelasma. Tendon xanthomata was present in almost 90% of patients by the age of 50 years. Arcus cornealis was present in about 45% by the age of 40 years, further increasing in frequency with age. Cardiovascular complications included ischaemic heart disease (43%), stroke (1.5%), transient ischaemic attacks (1.3%), and peripheral vascular disease (3.7%). The mean age of death was 55 (+13) years; 51 (+10) years in men and 61 (+12) years in women. In 46% of the cohort, a defective gene was identified by testing for locally prevalent mutations

Learners in the marketplace: Ethical and educational dilemmas
Since the abolishment of legislation (the South African Schools Act, No. 84 of 1996) stipulating that a learner may only attend a certain school in an area, there is great competition amongst schools to attract learners to their schools. There is a tendency to regard as commodities learners who can be seen as assets to the school, especially if these learners show a talent for sports and have outstanding sporting achievements. The main aim of the research was to determine whether school principals, learners and parents think that it is unethical to ‘buy’ talented learners. A qualitative research approach was undertaken to determine the views of a purposefully selected sample of school principals, learners and parents regarding the ‘buying’ of talented learners. These participants were chosen as they were important role players in the process of ‘buying’ talented learners. Data were collected by means of a questionnaire with semistructured and open-ended questions. The participants’ answers were critically analysed, and the ethical correctness was determined by evaluating them against the ethical ideas identified in five ethical approaches, namely the utilitarian approach, the rights approach, the fairness or justice approach, the virtue approach and the ethical problem solving approach. An extrapolation of these findings gives one an idea of our society’s attitude to the ‘buying’of talented learners and whether a need exists to actively create greater awareness of this practice. The findings are significant to illustrate the different viewpoints of school principals,talented learners and parents on the ethical and educational dilemmas of schools that ‘buy’ talented learners
