    The original publication is available at http://www.sajim.co.za/The Internet has brought about many new implications for the way we do business and is becoming a feature of normal business (Forster 2000). The most important implication is the way in which the Internet links many different entities in a vast network, creating a pool of information that is accessible from any location in the world. The computer screen is a small window into this pool of information, allowing us to interact with other participants in cyberspace. The most important aspect of the Internet from the point of view of this research is that it allows or facilitates the flow of business information, called e-business, between businesses and consumers, allowing business-to-business and business-to-consumer interaction. One of the possibilities brought about by the Internet is that of trading on-line, also called ecommerce. This opens up a new world that allows trade with global markets from any location. The ease with which we change things (information) in this environment may cause us to be indifferent to the parties with which we do business – as long as we are able to verify their secure identities. The modern treasury environment in a corporate treasury will be affected materially by the Internet. How treasury departments are being affected and will be affected in the future is important for South Africa. As a developing country, South Africa needs to take note of important changes in the global environment. If the country does not keep up with developments, the cost of catching up, which may be substantial, will place further unnecessary strain on the SA economy. E-business is seen as one of the most important enablers of business and it seems as if SA companies are already about 18 months to two years behind their counterparts in the USA (Gordon 2000:10). Generally, South African companies have not yet fully exploited the business advantages of new technologies (Duffield 2001:18). South African corporate treasuries realize the benefits of the e-business environment but need to take note of the changes and requirements necessary to fully exploit these benefits and to enable them to better manage the overall treasury function and the increased exposure to financial risk which may come about owing to mismanagement, fraud, inefficient systems or the use of modern financial instruments. Devastating losses may come about owing to the incorrect use of, for instance, derivative financial instruments. These instruments may leverage a dramatic loss (Holton 1998) and may threaten the future existence of a company. It is today also much easier to place most or all of the capital of a company at risk with one phone call. This just underlines how important it is to employ technology to improve the flow of business information for transactional, timely and accurate information for management purposes. The management of risk from the enterprise perspective therefore becomes vital.Publishers' Versio

    Teaching respect: a philosophical analysis

    Get PDF
    According to a Zulu proverb a human being can only become truly human because of others. Each person can only become more human, more himself- regardless of his sex - through the co-involvement of others. It is the love for one’s neighbour and the respect one has for him/her as a person which makes one consider the other party's feelings, viewpoints and circumstances. In order to arrive at a situation of peaceful coexistence it is important to realize that human attitudes and a mature life style evolve through a process of learning and interaction with others. It is a timeconsuming and costly process which starts at infancy and continues throughout someone's life. Instruction concerning interpersonal relations and the teaching of respect cannot be confined to individual lessons or working sessions at home or in school. Discussions and conversations concerning interpersonal relations need to form an integral and natural part of a child’s life within the home environment and throughout the pupil's school career. It is senseless if educators talk about the importance of teaching respect only to reveal disrespectful behaviour themselves, or to talk about the importance of self-esteem in the paying of respect whilst causing children to feel negative about themselves. To be able to express respect to other human beings, one needs to be respected. A child needs to experience how it feels when homage is paid. The following rule of life applies in this regard: one can never give if one has never received respect

    DOES RESEARCH AND DEVELOPMENT PAY - THE CASE FOR PROTEACEAE

    Get PDF
    This paper reports on the socio-economic impact of the Proteaceae technology development and transfer programme. Farm level data were collected from the major role players in the industry, including cultivators, harvesters, agents and nurseries. The five major production regions were the Western Cape, South Western Cape, Southern Cape, Cape Peninsula and Eastern Cape, but other small regions in the Republic of South Africa (RSA) were also included in the study. Standard pretested mail questionnaires, supplemented with personal interviews, were used. This paper reports the socio-economic impacts over the period 1974- 2005. Results show that the rate of return for the financial and economic analyses ranged between seven and twelve percent, showing that the research programme is a profitable investment to society. The Proteaceae programme contributed to the conservation of biodiversity, had institutional impact in terms of training and technology transfer, while the social impact was indicated by employment generation through R&D activities.Research and Development/Tech Change/Emerging Technologies,

    Characterization of LWRS Hybrid SiC-CMC-Zircaloy-4 Fuel Cladding after Gamma Irradiation

    The purpose of the gamma irradiation tests conducted at the Idaho National Laboratory (INL) was to obtain a better understanding of chemical interactions and potential changes in microstructural properties of a mock-up hybrid nuclear fuel cladding rodlet design (unfueled) in a simulated PWR water environment under irradiation conditions. The hybrid fuel rodlet design is being investigated under the Light Water Reactor Sustainability (LWRS) program for further development and testing of one of the possible advanced LWR nuclear fuel cladding designs. The gamma irradiation tests were performed in preparation for neutron irradiation tests planned for a silicon carbide (SiC) ceramic matrix composite (CMC) zircaloy-4 (Zr-4) hybrid fuel rodlet that may be tested in the INL Advanced Test Reactor (ATR) if the design is selected for further development and testin

    Allergic sensitisation in South Africa: Exploring regional variation in sensitisation

    Background. Allergy is a common health problem in South Africa (SA), and a rational approach to allergy testing is essential to ensure cost-effective as well as optimal patient diagnosis and management.Objectives. To review allergy testing data with respect to current national testing recommendations, and to explore the regional variations in sensitisation.Methods. Retrospective data review on allergy testing from a private pathology provider in SA over a 2-year period. Data on skin-prick testing (SPT) and allergen-specific IgE testing originating from all the provinces of SA were collected and analysed with regards to allergen positivity rate and regional sensitisation patterns.Results. Among the patients (N=45 0320) tested for a suspected inhalant allergy, 46% tested positive. Only 45% of these received additional testing for the nine recommended inhalant allergens included in the current national testing protocol. Among the patients (N=6 775) who received SPT for a suspected inhalant allergy, 59% yielded one or more positive results. The most frequent sensitising allergens were house dust mite (Dermatophagoides pteronyssinus) and grass pollen. The house dust mite, Blomia tropicalis, was a significant sensitiser in coastal regions. SPT identified two other important regional allergens which are not included in the current recommendations for inhalant allergen-specific IgE testing.Conclusions. The current diagnostic recommendations include allergens that demonstrate significant sensitisation in all regions of SA. Two additional allergens that show significant regional sensitisation in the South African population were identified. These findings may aid the recommendations for the most appropriate and cost-effective approach to allergy testing of symptomatic patients in SA

    The dry friction and sliding wear behavior of sintered polytetrafluoro ethylene containing various amounts of functionalized graphene were studied in this work. Graphene was incorporated in 0, 0.25, 0.75, 1, 2 and 4 vol.%, respectively. Sliding wear tests were performed in ring(metal)-on-plate(polytetrafluoro ethylene) test rig under ambient temperature setting 1 m/s sliding speed and 1 MPa contact pressure. The dynamic coefficient of friction and specific wear rate (ws) data were determined. Very low coefficient of frictions (0.12–0.14) were measured for polytetrafluoro ethylene containing 2 or 4 vol.% graphene, which was attributed to the formation of a tribofilm on the countersurface. Specific wear rate went through a maximum (peaked at doubling that of the unmodified polytetrafluoro ethylene at about 0.75 vol.% graphene) as a function of graphene content. Ultralow wear rate data in the range of 10−6 mm3/(N.m) were measured for the polytetrafluoro ethylene nanocomposites with 2 and 4 vol.% graphene. This was reasoned by the formation of a robust tribofilm, the development of which was followed by scanning electron microscopy by inspecting the worn surface of polytetrafluoro ethylene nanocomposites and that of the steel ring of the ring(metal)-on-plate(polytetrafluoro ethylene) test rig. Fourier transform infrared spectroscopic results confirmed the formation of carboxyl groups in the tribofilm. They were supposed to react with the functional groups of graphene and to create complexes with the metal countersurface ensuring the tribofilm with high adhesion and cohesion strengths. </jats:p
