Financial impacts of changing technology on business case study : Hyflo Southern Africa (PTY) LTD

De Wet, Pierre January 2005 (has links)
Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2005 / The era kno"n as the Industrial Revolution was a period in which fundamental changes occurred in agriculture, textile and metal manufacture, transportation, the social structure and economic policies. The large number of unskilled people provided cheap labour and was used as easy replaceable tools. Employees have since become companies' most expensive '''assets''. The Internet was originally designed for military applications. The US military wanted a network that could withstand a terrorist attack and stilI work if important communication areas had been destroyed. The Internet, also known as the giant network of networks, has become a major catalyst for electronic business. The Internet caused the shape of companies to change and the way they conduct business. For example the Intemet enabled companies to be run from home and changed the old companies' structures. Sending data via a network is a lot faster and less expensive than making a telephone call or sending a messenger. Businesses have become more dependent on the Internet to generate revenue. E-commerce refers to the buying and selling of goods and services on the Internet and reduces the cost of doing business. The down side is that companies are also more exposed to inherent security risks. New technology with old methods of working is also no longer feasible. Many clerical tasks disappear and both the job functions of staff and the supervisory functions and procedures change. Information technology (IT) is increasing productivity, and thus, for a given output, a smaller number of people are employed. Increasing numbers of workers are retrenched when still in mid-career because labour is a most expensive commodity. The reduction in overheads and improved response of modem administrative systems increase the opportunities for organisations of all sizes to compete on an international level.

Mentoring as a support intervention for the entrepreneurs of Peninsula Technikon's Technology Enterprise Centre

Petersen, Tania January 2002 (has links)
Thesis (MTech (Entrepreneurship))--Peninsula Technikon, Cape Town, 2002 / By international standards South Africa's unemployment rate and poverty levels are extremely high. Currently the unemployment rate is approximately 30% (Business Day, 28 March 2002) or in the region of 40% if those who are not actively seeking work are included. Owing to the high unemployment rate, the informal sector has experienced a growth spurt. Unfortunately, due to a lack of entrepreneurial competencies, South Africa's start-up businesses also have a lower survival rate compared to their international counterparts. Technology Enterprise Centres (TECs) were created by the Technical and Business Initiative in South Africa (TABEISA), a consortium of six South African and British institutions established in 1994. The TEC has developed a mentoring programme and aims to implement it in the near future. As part of a wide assortment of assistance programmes, mentoring is the latest methodology that is being promoted by the private and public sector as a valuable developmental tool for entrepreneurs. The purpose of this study is to examine mentoring as an important resource in extending the business life-cycle of the entrepreneurs of Peninsula Technikon' s TEC. The research reviews the mentoring literature and covers aspects such as the characteristics that mentors should have, the role of mentors, types of mentoring programmes, setting up a mentoring programme, current mentoring programmes, implementing a mentoring programme, as well as the benefits and drawbacks of mentoring. The survey concentrated on identifying the mentoring requirements of the businesses. The findings highlight the need for a mentoring support programme to help entrepreneurs develop faster, therefore smoothing the transition process from one business stage to another. The study concludes by stressing the need for an efficiently run formal mentoring process, coupled with other developmental programmes.

The influence of oceanographic conditions and culture methods on the dynamics of mussel farming in Saldanha Bay, South Africa

Heasman, Kevin Gerald January 1996 (has links)
The principal aim of this study was to establish the biological and environmental parameters governing the successful and sustainable cultivation of mussels in Saldanha Bay. The environmental study investigated seston, chlorophyll-a and particulate organic matter (POM) levels, water temperature dissolved oxygen and salinity levels in the bay and water flow in and around the rafts. The biological part of the study investigated the efficiency of food extraction, growth rates, mussel condition, fouling and production and yield on a rope, raft and farm scale. Saldanha Bay is well suited for the culture of mussels, particularly Mytilus galloprovincialis and Choromytilus meridionalis. Water temperature and salinity in Saldanha Bay were found to be near optimal for mussel culture. POM and chlorophyll-a levels were found to be high due to primary production resulting from the nutrient rich upwelled water outside Saldanha Bay. The mean levels of chlorophyll-a (8,6μg/l) represent 6%, by mass, of the total POM. On a bay scale the POM remained above the mussels maximum requirements (pseudofaeces threshold) during the study period. Mussels showed a preference for the phytoplankton portion of the POM. Approximately 40% of the chlorophyll-a was extracted from the water by the mussel farm. The efficiency of food extraction increased with mussel age. Rafts with seed mussels younger than 2 months, 3 to 4 months, 5 to 6 months and older than 6 months extracted 32%, 55%, 85% and 92% of the available chlorophyll-a respectively. An increase of rope spacing on the rafts resulted in 37% more chlorophyll-a and 30% more particle volume reaching the lee of the raft. Ambient water currents in the bay show flow rates of up to 22cm per second. However, on entering a raft with a rope spacing of 60cm, the water flow is attenuated by 90%. Increasing the rope spacing to 90cm resulted in a water flow attenuation of 72%. The increase in rope spacing ensures that the mussels in the centre of the raft are feeding on food levels close to, or above, the pseudofaeces level. Mussel growth rate at a rope spacing of 90cm is significantly improved as a result of the increased food delivery. There are other factors, however that effect mussel growth. Growth rates were found to be better in summer than in winter. The reduced winter growth rate is possibly due to competition with the maturing fouling organisms which settle in mid to late summer. Fouling by mussel spat and Ciona intestinalis is seasonal, occurring from December to May. C.intestinalis is prevalent in the centre of the farm and rafts as low energy waters are preferred by this species. Mussel spat settles mainly on the periphery of the farm and the rafts. Competition with fouling organisms reduces growth and increases mortality of the cultured mussels. Results indicate that the present spacing of rafts, (1 raft per hectare) is adequate under existing conditions. Any new farms should maintain batches of 50 rafts with channels between them to ensure water current penetration into the furthest reaches of the farm. Rope spacing on the rafts should be increased to between 60cm and 90cm. Mussel density should be regulated according to mussel size and fouling should be controlled to maintain yields.

Modale verdeling van die Suid-Afrikaanse vragvervoermark

Louw, Jacobus Hendrik 12 March 2014 (has links)
D. Com. (Transport Management) / The objective of this study was to obtain information and an understanding about the nature and magnitude of the South African freight transport market, as well as to establish the relative importance and/or position of the various transport modes from a transport economic point of view. The underlying rationale was the lack of information in this regard in South Africa. In an effort to help overcome this lack of information the stUdy concentrated on the following: the magnitude of the freight transport market the participants in this market the market share of each participant the products being transported the geographical location and distribution of the transport undertakings. Information about the freight transport market in South Africa was obtained on a sectoral basis by means 'of a literature analysis and an empirical investigation (field study).

The accreditation and implementation of the formal literacy route in a post apartheid South Africa : an investigation into how the ABET route fulfills the needs of the adult learner, the corporate sector and the economic development of South Africa

Vivian, Brenda Ann 27 August 2012 (has links)
M.A. / Even before the first democratic elections in South Africa in 1994, many Non-Governmental Organisations carried the torch of literacy for those South Africans who were not given the opportunity to learn to read and write, due to the inequalities of the apartheid education policies. Subsequent to the 1994 elections, the government took steps to formalise literacy initiatives and, in so doing, create national standards. Hence the birth of Adult Basic Education and Training. With the emergence of the South African Qualifications Authority, the ABET route was integrated into the National Qualifications Framework as part of the overall vision for standardised education in South Africa. Presently, the ABET route is mainly sponsored by the private sector who have shouldered the costs of these adult literacy initiatives. The formal ABET route is assessed by the Independent Examinations Board. This study illustrates how the formal ABET route does not adequately meet the goals of the department of Education in terms of its goals for reconstruction and development, nor does it guarantee the learner an improved future life, nor does it provide the private sector with the competencies they had hoped for in the workplace. Two of the most significant shortcomings of the formal ABET route were found to be the assessment process and the difficulty of the facilitation between the ABET route and qualification on the NQF. Based on the findings of this research, recommendations have been made. These aim to improve the flexibility of the ABET route and provide a number of options which may be more suitable for the needs of the learners, the corporate sector and the economy of South Africa as a whole.

Neighbourhood renewal in Parkhurst, Johannesburg : a case study of gentrification?

Monare, Tsietsi Paul 11 February 2014 (has links)
M.Sc. (Environmental Management) / As in many other countries, the processes of gentrification in South Africa have taken the form of urban regeneration. However, little geographical research has been conducted on gentrification in South Africa. This study adds to the literature by presenting the case of Parkhurst, a Johannesburg surburb, that has undergone gentrification. Parkhurst displays three of the four characteristics of gentrification: (1) the housing stock has undergone extensive physical improvement (2) property values have increased and (3) the original residents have been displaced. Although gentrification is usually also associated with a change in housing tenure from rentals to ownership, it was found that ownership was, and still is, a common feature, both prior to, and subsequent to, gentrification. The study found that Parkhurst has a demographic and a socio-economic profile typical of a gentrified suburb in that it is populated by young, educated and childless couples, many of whom are high- income-earning professionals, and new residents to the area. Due to its past designation as white space, this suburb is still a reflection of South Africa’s racially stratified past in that it is still numerically dominated by white people. Furthermore, the gender ratio is skewed in favour of males. Almost one third of the housing stock has been renovated or is under renovation. Some of the residential stands in the suburb have been converted into business units such as restaurants and antique shops. This research concluded that for Parkhurst the process of gentrification has been driven by consumptive patterns of behaviour, with individual consumption patterns in particular driving the process.

Particle precipitation effects on the South African ionosphere

Sibanda, Patrick January 2007 (has links)
Particle precipitation involves the injection of energetic particles into the ionosphere which could increase the ionisation and conductivity of the upper atmosphere. The goal of this study was to examine the ionospheric response and changes due to particle precipitation in the region over South Africa, using a combination of groundbased and satellite instruments. Particle precipitation events were identified from satellite particle flux measurements of the Defence Meteorological Satellite Program (DMSP). Comprehensive studies were done on the events of 5 April, 2000 and 7 October, 2000. Analysis of the data from the satellite instruments indicates that no particle precipitation was observed over the South African region during these events and that it is unlikely to occur during other such events. To validate the data, methods and tools used in this study, precipitation in the South Atlantic anomaly (SAA) region is used. Satellite ion density measurements revealed that strong density enhancements occurred over the SAA region at satellite altitudes during the precipitation events, but this did not occur in the South African region. The measurements also revealed how the ionisation enhancements in the SAA region correlated with geomagnetic and solar activities. Particle precipitation and convective electric fields are two major magnetospheric energy sources to the upper atmosphere in the auroral and the SAA regions. These increase dramatically during geomagnetic storms and can disturb thermospheric circulation in the atmosphere and alter the rates of production and recombination of the ionised species. Ionosonde observations at Grahamstown, South Africa (33.30S, 26.50E), provided the data to build a picture of the response of the ionosphere over the South African region to particle precipitation during the precipitation events. This analysis showed that, within the confines of the available data, no direct connections between particle precipitation events and disturbances in the ionosphere over this region were revealed.

The design and testing of a national estuarine monitoring prgramme for South Africa

Cilliers, Gerhard Jordaan January 2017 (has links)
Adaptive water resource management requires sound scientific based decisions, emanating from robust scientific data. The Department of Environmental Affairs are mandated for collaborative management of the South African coast, including estuaries, through the Integrated Coastal Management Act (Act no 24 of 2008) (ICMA). The Department Water and Sanitation is mandated through the National Water Act (Act no 36 of 1998) (NWA) to design, test and implement monitoring programmes to provide water resource data. Extensive freshwater monitoring programmes exist in South Africa but there is no standard long-term monitoring programme for estuaries. This study designed and tested a National Estuarine Monitoring Programme (NESMP) that is anchored in the NWA and the ICMA. The design was based on a review of international estuary monitoring programmes, consultation with relevant role players and five decades experience in the design, testing and implementation of water resource monitoring programmes by DWS. The main objective of this thesis is 1) to design a national estuarine monitoring programme 2) test the design of the programme for practical implementation by reflecting on collected data from case studies, and 3) design a Decision Support System to translate complex monitoring data into management information. The main objective of the NESMP is 1) to collect long-term data to determine trends in the condition of estuaries in South Africa and 2) to provide management orientated information for effective estuary management. The National Estuary Monitoring programme consists of three tiers. Tier 1 focuses on basic data including system variables and nutrient data. Tier 2 collects data required for the determination of the Ecological Water Requirements (EWR) of estuaries in accordance with a standardised method used by DWS. A tailor made monitoring programme addressing specific issues including pollution incidents and localised development pressure, making use of a combination of Tier 1 and Tier 2 components, forms Tier 3 of the NESMP. This study tested the Tier 1 components of the programme on 28 estuaries across the South African coast since 2012. However, due to space constraints, the data reflected on in this thesis, is only for case studies on the Berg and Breede estuaries between 2012 and 2016. The results indicate that the establishment and operation of the NESMP on South African estuaries making use of monthly surveys, and the deployment of permanent water quality loggers, in line with the proposed protocol, are possible. This does however require collaboration with other role players in order to share responsibility and associated resources. A tiered management structure ensures national, regional and local level implementation takes place seamlessly. A decision support system (DSS) was also designed as part of this thesis to assist with data interpretation and the creation of management orientated information. This DSS includes a measurement of the percentage exceedance of the Threshold of Potential Concern (TPC), which acts as an early warning system for water resource deterioration. This study showed that effective collaboration will ensure the sustainability of the NESMP. Implementation of the more complex and resource intensive Tier 2 and Tier 3 sampling will however need to be investigated to establish the overall success of the NESMP.
