Dubai’s Electronic Transactions Law (“ETL”) is designed to stimulate E‐commerce in the emirate by improving the authenticity and integrity of electronic transactions. The ETL recognizes the legal validity of electronic documents and electronic signatures as acceptable substitutes for paper documents and ink signatures, respectively. Accordingly, electronic records may be used to comply with a statutory writing requirement, original document requirement and retention requirement, and an electronic signature attached to an electronic document may be used to comply with a statutory requirement for a paper‐and‐ink signature. If all parties are in agreement, a contract may be in electronic form and is just as legally enforceable as a written one. The ETL does not mandate Dubai’s governmental agencies to utilize electronic documents, but they may elect to do so. The ETL has created a compulsory system of licensing of Certification Authorities (“CA”). Their role is to ascertain the identity of a subscriber and to attest in an issued Certificate that the electronic signature used by that subscriber belongs to him. The ETL contains a list of computer crimes. The statute establishes a sound framework for E‐commerce, but it could be improved by adding consumer protections, more computer crimes, mandatory Egovernment, I.T. courts and long‐arm jurisdiction. The ETL’s exclusion of wills should be eliminated.

The idea of competitive advantage is not new. What is new is the growing acceptance of this planning concept as a general philosophy of management. In all likelihood, the notion of competitive advantage will provide the guiding philosophy for the predominant management practice of the 1980s: strategic management. As experience at Clark Equipment Company shows, the answers to eight key questions can spell out a winning strategy.

Like many midwestern companies that decades ago started business in industries now considered basic, Borg‐Warner currently has a number of strategic business units in mature industries.

Over the last two decades the average floor area of new houses in Australia has increased significantly. This has coincided with greater expectations of thermal comfort in homes. In certain locations, the result has been an escalation of the use of large mechanical air conditioning systems in houses. Since it is predicted that climate change will lead to an increase in the frequency and severity of extreme weather events such as heatwaves, the future maintenance of thermal comfort in houses in an affordable manner is likely to be challenging. This will have implications not only for the health and comfort of the occupants but also for peak energy loads. A compounding factor is the likelihood of increased energy prices caused, in part, by financial mechanisms aimed at minimising greenhouse gas emissions. There will be sections of the community, such as the elderly and the less well off, that will be particularly vulnerable to these combined factors.

This paper explores design strategies that could be incorporated in new and existing houses to improve thermal comfort for residents during heatwaves. It is shown that during such periods, behaviour change, thermal comfort requirements and extra energy consumption have a strong influence on devising solutions for this challenge. The results of a pilot study are given that indicate opportunities for creating cool refuges in the existing dwelling stock.

The purpose of this paper is to present challenges and opportunities of e‐government implementation in South Africa with special reference to service delivery and implications for libraries.

The paper is based on an in‐depth literature review from government documents, presidential state of the nation addresses, global and nation reports on e‐government, and reports on service delivery concerns in South Africa.

The Government of South Africa has put in place enabling policies, poverty alleviation programmes, ICT infrastructures and regulatory frameworks which as yet have not been effectively leveraged to enhance service delivery to its citizens. Furthermore, libraries have yet to make any attempts to benefit from the emergence of e‐government in South Africa.

There is a need to infuse an e‐government ethos in poverty alleviation programmes in order to enhance service delivery. At the moment there is a lack of synergy between the two in South Africa. Additionally, South African ICT infrastructure is under‐utilised to enhance service delivery. Libraries have the opportunity using e‐government infrastructure to improve the provision of information services to the people.

Service delivery remains a priority for the post‐apartheid South African government, and the paper reveals that a disconnect exists between the e‐government vision and the poverty alleviation programmes aimed at enhancing the standard of living of the people. Libraries in South Africa have yet to leverage e‐government to provide information services and the paper may assist them in doing so.

The purpose of this paper is to explore the professional biography of Ethel A. Stephens, examining her career as an artist and a teacher in Sydney between 1890 and 1920. Accounts of (both male and female) artists in this period often dismiss their teaching as just a means to pay the bills. This paper focuses attention on Stephens’ teaching and considers how this, combined with her artistic practice, influenced her students.

Using a fragmentary record of a successful female artist and teacher, this paper considers the role of art education and a career in the arts for respectable middle-class women.

Stephens’ actions and experiences show the ways she negotiated between the public and private sphere. Close examination of her “at home” exhibitions demonstrates one way in which these worlds came together as sites, enabling her to identify as an artist, a teacher and as a respectable middle-class woman.

This paper offers insight into the ways women negotiated the Sydney art scene and found opportunities for art education outside of the established modes.

This paper aims to show that by using air source heat pump (ASHP) water heater in the residential sector, the energy consumption from sanitary hot water production can be reduced by more than 50 per cent. Hence, this study quantitatively and qualitatively confirms that domestic ASHP water heater is a renewable and energy efficient device for sanitary hot water production.

Design and building of a data acquisition system comprises a data logger, power meters, flow meters, temperature sensors, ambient and relative humidity sensor and an electronic input pulse adapter to monitor the ASHP water heater performance. All the sensors are accommodated by the U30-NRC data logger. The temperature sensors are installed on the inlet pipe containing a flow meter and the outlet pipe of the ASHP unit, the vicinity of both evaporator and expel cold air. An additional temperature sensor and a flow meter that cater for hot water drawn off measurements are incorporated into the data acquisition system (DAS).

The result from a specific monitoring split type ASHP water heater gives an average daily coefficient of performance (COP) of 2.36 and the total electrical energy of 4.15 kWh, and volume of hot water drawn off was 273 L. These results were influenced by ambient temperature and relative humidity.

The cost involved in purchasing the entire sensors and data logger limits the number and categories of ASHP water heaters whose performance were going to be monitored. Pressure sensors were excluded in the data acquisition system.

The data acquisition system can easily be designed and the logger can also be easily programed. Hence, no high technical or computer skills are needed to install the DAS and to be able to read out the results.

Hence, the data acquisition system can be installed on the entire domestic Eskom roll out air source heat pump water heaters to effectively determine the coefficient of performance and demand reductions.

This DAS is the first of its kind to be built in South Africa to be used to determine the performance of an ASHP water heater with high accuracy and precision. DAS is also robust.

This paper aims to investigate the electronic short books phenomenon from the USA and the UK which has spilled over to South Africa. By looking at the benefits these short books have for readers and authors, and the possible reasons for their success, the aim is to determine whether or not these books can be as successful a venture in South Africa as it has been elsewhere.

Information about electronic short books, or e-singles, is gathered from various sources, including press releases and sales results. Information is gathered to determine the receptiveness to electronic short books of the South African trade book reading market, the way South African publishers are presenting e-singles to the market and what the future for e-singles may be.

The findings of this paper make it clear that e-singles have found a gap in the market, providing various benefits to authors and readers, which may have contributed to their success. In South Africa, the success of e-singles faces unique obstacles, like a weaker reading culture and a poor awareness of e-books. Publishers need to make a bigger effort to become visible in the eyes of their readers and need to think about better distribution strategies.

With comparisons, accuracy is dependent on information provided by organizations (on their Web sites).

This paper offers information about a new publishing trend – only a few months in South Africa. It offers a look into the state of the trade book industry in South Africa, how e-singles may function in it and what publishers of e-singles may do to ensure more success. It predicts the future of e-singles in South Africa based on its unique situation, pointing out what obstacles there may be to their uptake.
