This paper reports on an investigation into the possibility of implementing activity‐based costing and activity‐based management in the Fuel Purchases Department of Eskom. This Department purchases coal from various mines on behalf of ten power stations. The problem is that power stations are charged by the Fuel Purchases Department in accordance with the quantity of coal that is purchased on their behalf and in not accordance with the quantity of work done. Activity‐based costing resolves this problem by using seven cost pools and seven cost drivers to allocate the cost of the Fuel Purchases Department to the power stations. This leads to a more accurate cost allocation and cross‐subsidising between power stations is also eliminated. Activity‐based costing also provides information on activities in the Department. This clears the way for activity‐based management.

The purpose of this paper is to assess the efficiency of agricultural production in South Africa from 1970 to 2014, using an integrated two-stage fuzzy approach.

Fuzzy technique for order preference by similarity to ideal solution is used to assess the relative efficiency of agriculture in South Africa over the course of the years in the first stage. In the second stage, fuzzy regressions based on different rule-based systems are used to predict the impact of socio-economic and demographic variables on agricultural efficiency. They are compared with the bootstrapped truncated regressions with conditional α levels proposed in Wanke et al. (2016a).

The results show that the fuzzy efficiency estimates ranged from 0.40 to 0.68 implying inefficiency in South African agriculture. The results further reveal that research and development, land quality, health expenditure–population growth ratio have a significant, positive impact on efficiency levels, besides the GINI index. In terms of accuracy, fuzzy regressions outperformed the bootstrapped truncated regressions with conditional α levels proposed in Wanke et al. (2015).

Policies to increase social expenditure especially in terms of health and hence productivity should be prioritized. Also policies aimed at conserving the environment and hence the quality of land is needed.

The Milk and Cream Standards Committee, of which Lord WENLOCK is Chairman, have commenced to take evidence, and at the outset have been met by the difficulty which must necessarily attach to the fixing of a legal standard for most food products. The problem, which is applicable also to other food materials, is to fix a standard for milk, cream and butter which shall be fair and just both to the producer and the consumer. The variation in the composition of these and other food products is well known to be such that, while standards may be arrived at which will make for the protection of the public against the supply of grossly‐adulterated articles, standards which shall insure the supply of articles of good quality cannot possibly be established by legal enactments. If the Committee has not yet arrived at this conclusion we can safely predict that they will be compelled to do so. A legal standard must necessarily be the lowest which can possibly be established, in order to avoid doing injustice to producers and vendors. The labours of the Committee will no doubt have a good effect in certain directions, but they cannot result in affording protection and support to the vendor of superior products as against the vendor of inferior ones and as against the vendor of products which are brought down by adulteration to the lowest legal limits. Neither the labours of this committee nor of any similar committee appointed in the future can result in the establishment of standards which will give a guarantee to the consumer that he is receiving a product which has not been tampered with and which is of high, or even of fair, quality.

The mining sector represents a significant portion of the South African economy. The recent announcement of the proposed black empowerment bill for the mining sector caused share prices to plummet. This reaction, in turn, caused a marked devaluation of the rand against other major currencies. Anything that impacts negatively on the mining sector will therefore have an adverse effect on the South African economy. This paper considers the affect that HIV/AIDS will have on the mining sector and, by implication, on the South African economy. Consideration is given to whether mining companies manage this risk properly and whether it is reasonably accounted for and disclosed in the financial statements. Conclusions are drawn and recommendations made regarding HIV/AIDS risk management and how HIV/AIDS issues can be disclosed fairly. Although the management teams of mining companies have introduced a HIV/AIDS risk‐management process and have commenced the disclosure of HIV/AIDS information, the disclosure is still far from adequate.

In the Earth’s upper atmosphere, damage to satellite electronics is caused by exposure to extreme ultraviolet (EUV) radiation. One particular region where this type of radiation occurs is the South Atlantic Magnetic Anomaly region. As a result, there is a need to design and develop a sensor which could be used to investigate the flux and energy levels of radiation in this region. To do so, the aim of this study is to characterise the sensor and its electric response to typical EUV radiation levels based on the photoelectric effect principle.

For this purpose, a copper plate planar sensor prototype with dimensions that fit on the sides of a one-unit (1U) CubeSat was constructed. The sensor prototype was placed in a vacuum chamber and was subjected to continuous radiation from a vacuum ultraviolet deuterium light source at test facilities available in the Western Cape region (South Africa). Subsequently, the terminal voltage of the sensor was measured and compared with theory.

The measured time-averaged terminal voltages indicate the generation of photocurrents of the order of 1 μA, which is consistent with theory.

Conclusively, these results validate the measurement approach and operation of the sensor, which can be used to design a 1U CubeSat sensor that measures EUV radiation in low Earth orbit.

This study aims to provide a cutting-edge evaluation of the sharing economy's impact within the realm of tourism and hospitality. The primary objectives guiding this research are as follows: to uncover the prevalent discussions and debates within the tourism and hospitality sector concerning the implications and effects of the sharing economy on urban destinations; and to analyse how scholarly inquiries and empirical investigations have contributed to a comprehensive comprehension of the intricate theoretical foundations and practical intricacies inherent in the sharing economy. This exploration takes place within the extensive expanse of existing literature.

The study used the non-conventional method for data mining. An artificial intelligence (AI) tool called www.dimensions.ai was used to mine data between the year 2002 and 2021. After which the data was analysed, using Citespace software that assisted in building themes for answering the research questions.

The sharing economy has multifaceted implications for rural and urban destinations. For instance, the findings demonstrated that emotional solidarity fosters community bonds between tourists and residents, enhancing authenticity. While, management firms optimise short-term rentals, boosting revenue and occupancy rates despite capped at 20%. It further demonstrated that the sharing economy disrupts traditional accommodations, especially hotels, impacting rural and urban destinations differently based on location and regulatory flexibility. Technological advancements would shape the digital future, transforming the resource in sharing and connectivity in urban settings.

Management firms or agents significantly enhance property facilities, revenue and occupancy rates. Properties managed by professionals perform better in terms of revenue and occupancy; furthermore, traditional accommodations need innovative strategies to compete with sharing economy platforms. Policymakers must consider location-specific regulations to balance sharing economy impacts. Embracing technological advancements ensures urban destinations stay relevant and competitive.

Emotional solidarity fosters bonds between residents and tourists, contributing to a sense of community. Management firms contribute to local economies and stability. However, Airbnb's impact on traditional accommodations raises concerns about the effect on residents and communities.

The study incorporates classical sociology theory to understand emotional solidarity and extends the concept of moral economy to guide economic behaviour in the sharing economy. The analysis also underscores the influence of technological trends such as mobile technology, Internet of Things, AI and blockchain on sharing practices in reshaping existing theoretical frameworks in the sharing atmosphere. Furthermore, the co-creation of value theory highlights collaborative interactions between hosts and guests, shaping the sharing economy experience. Consumer segmentation and choice theories shed light on sharing economy dynamics. Institutional and location-based theories provide insights into regulatory and location-specific impacts.

This research contributes by comprehensively exploring the multifaceted implications of the sharing economy on a tourist destination. It delves into emotional solidarity, management firm roles and location-specific impacts, enriching the understanding of the sharing economy's effects. The application of co-creation of value theory and examination of platform technologies offer fresh perspectives on value creation and user engagement. The study's focus on practical dimensions guides stakeholders in optimising the benefits and addressing challenges posed by the sharing economy in urban contexts. The exploration of moral economy and its relevance to the sharing economy provides a novel perspective, while the examination of technological influences on sharing practices contributes to understanding the digital future of the sharing economy.

This article develops an econometric valuation methodology that is applied to identifying value in South African red wines. It is found that quality, as simultaneously measured by Wine magazine and Platter star ratings, is the dominant factor in explaining the cross‐section of prices. However, together with a varietal dummy these factors are only able to explain about 40% of the variation in wine prices. This implies that there is considerable value that may be gleaned through informed bargain seeking using this tool. Indeed, at certain levels of value there is more than a 50% differential in price.

Proceeding from the van Rensburg and Priilaid (“An econometric model for identifying value in South African red wine”, International Journal of Wine Marketing, Vol. 16 No. 1, 2004, pp. 37‐53) econometric valuation methodology mapping out the relationship between wine price and value, this paper seeks to explore the relationship between wine value and value‐for‐money.

A series of regression models are developed from a database of some 537 South African red wines available during the 2004 period. Five cultivars are included here: cabernet, merlot pinotage, pinot noir, and shiraz.

This research finds that successive increments in wine quality ratings are not equally priced. As a result, the relationship between value and price can be better modelled when increments in wine quality (as measured in stars) are proxied by dummy variables.

Allowing for the possibility of the non‐linear hedonic pricing of wine avoids the bias of value‐for‐money misleadingly being identified excessively at the bottom end of the quality spectrum and neglected at the top end.

In an attempt to enhance the core professional values of tax practitioners in South Africa, the South African Revenue Service has proposed the regulation of tax practitioners’ services. It is arguable whether or not this would be the only factor to influence the ethical behaviour of tax practitioners. A literature review was conducted to identify factors that could influence the ethical behaviour of tax practitioners. Numerous possibilities emerged. It is therefore recommended that if regulation is to be successful, caution should be exercised in writing a code of best practice for tax practitioners.
