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.

Describes recent research on consumer behaviour and buying patterns and health. Suggests that health awareness has increased, that health issues are of growing concern, and that this is reflected in consumer behaviour. Age and demography also play a part. Discusses the repertoire effect using specific products as case examples.

This study assesses the impact of marital status towards customer-centric measures in a Canadian ski resort using the importance-performance map analysis (IPMA) as the analytical framework. For the purpose of this paper, the three groups that were assessed included singles, partnership without children and partnership with children as marital status indicators. From the theoretical and especially managerial point of view, knowing the importance and the performance of the relevant ski resort-related customer-centric perceptions is of key importance.

A survey was completed to assess customer-centric measures including customer satisfaction, repurchase intent, value for money, willingness to recommend, overall performance in terms of meeting expectations, relationship quality and skiing service quality. An IPMA was conducted with partial least square-structural equation modelling (PLS-SEM) to assess the importance-performance perceptions of the three marital status groups.

The results indicated that for five of the seven customer-centric measures, there were significant differences between the marital status groups. Overall, singles appeared to have the lowest values in customer-centric measures, whereas respondents living in partnership with children had the highest. This was also the case with the value for money perceptions, although the cost for the ski resort visit was likely to be the highest for the respondents living in partnership with children. There were also differences between the marital status groups in terms of the importance-performance evaluations.

Results of this research have implications for ski resort management as the three marital status groups appear to perceive the customer-centric measures quite differently in the IPMA framework.

The purpose of this paper is to evaluate experiences of female international business travellers living in dual-career families (DCFs) who also have childcare obligations. In particular, the paper explores in which way different sources of support – specifically organizational support – are perceived as important and are available to the women under research. Because of the women’s regular absences due to business trips and the fulfilment of their family role, challenges regarding childcare or household responsibilities may occur. Consequently and also according to social support theory, different types of support may be necessary to organize family and international career, and effectively perform in both environments.

This paper examines the experiences and thoughts of these women with special regards on support issues. Data are collected from 51 semi-structured interviews with internationally travelling women in DCF situations originating from seven Western and non-Western countries. The interviews are analysed applying template analysis.

Results show that, across countries, support is mainly derived from within family. Regarding institutional or organizational support, however, the reported expectations and actually offered activities differ because of local institutional and cultural variations. The examined women value different forms of organizational support, but do not necessarily expect it.

This paper represents the first exploratory examinations of various forms of support for female international business travellers in DCFs suggested by social support theory. It includes a culturally diverse sample and contributes to cross-cultural career research.

The consumption of wine is influenced by seemingly contradictory antecedents such as perceived authenticity and novelty. This paper aims to explore the influence novelty and authenticity have on wine consumption, in the context of the moderating variables of regionality (i.e. single and multi-region wines) and price (low and high). The research attempts to further understand wine consumption by establishing a conceptual model built on existing wine literature.

To address the hypotheses and research questions, a panel of 658 consumers who regularly purchased wines produced by the Australian wine industry were recruited. These participants completed a self-administered questionnaire containing stimuli to measure perceived authenticity, perceived novelty, perceived quality, attitudes and purchase intent towards a wine manipulated to have a low vs high price level, as well as single vs multi-regional label. To examine these variables, the study conducted a confirmatory factor analysis (CFA) to confirm the dimensionality of the constructs and structural equation modeling with both path and multi-group analyses to investigate the hypothesised relationships.

The findings revealed that both authenticity and novelty simultaneously influence perceived quality. Additionally, it was acknowledged that there is no significant difference in wine consumption between single and multi-regional wines; reinforcing current trends of collaboration within the wine industry. Finally, the results also showed that price does moderate wine consumption; revealing ideal prices for wine with particular regional branding strategies.

The current research is the first to show that authenticity and novelty simultaneously and positively influence consumer’s perceived quality of Australian wine. The findings are also the first to show that consumer evaluation of single and multi-origin wines was positive and yielded no significant difference, suggesting that branding wines with multi-origins or multi-region do not change consumers’ perception.

Probiotic fermented foods are fast being recognized as health foods. Most of such developed foods are based on dairy products and much less work is available on cereals/legumes which constitute the staple diet in developing nations. In the present study an attempt has been made to develop a barley‐based probiotic fermented food mixture and report its acceptability and nutritional profile.

Indigenously developed BCGT food mixture containing barley flour, milk coprecipitate, sprouted green gram paste and tomato pulp (2:1:1:1, w/w) was autoclaved (1.5kg/cm², 15min., 121^○C), cooled and fermented with 2 per cent liquid culture (containing 10⁶ cells/ml broth). Two types of fermentations were carried out i.e. single culture fermentation [ L. casei, L. plantarum (37^○C, 24hr.)] and sequential culture fermentation [S. boulardii (25^○C, 24hr.)+L. casei (37^○C, 24hr.); S. boulardii (25^○C, 24hr.)+L. plantarum (37^○C, 24hr.)]. The lyophilized and rehydrated food mixtures were subjected to organoleptic and nutritional evaluation. The data were statistically analysed for analysis of variance in a completely randomized design according to standard methods.

All the fermented and lyophilized food mixtures were found to be organoleptically acceptable to human palate and maintained adequate cell viability. The pH of the fermented products varied from 4.13 to 4.55. They had good nutrient profile with crude protein content ranging from 20.87 to 21.81 per cent.

Since the developed product had good acceptability after one month storage at room temperature, it can be considered for commercialization after establishing its health/therapeutic implications.

Till date dairy foods have preferentially been used as the carrier medium for probiotics. This paper explores the possibility of using staple foods as the carrier medium. The consumption of such food mixtures may be useful in controlling pathogens/antibiotics induced diarrhoea as well as in hypercholesterolemia. To authenticate such claims, the results of trials carried out on mice in our lab shall be reported in future communications.

The purpose of this paper is to report on a study of the movement of the powder bed material during selective laser sintering (SLS) of bisphenol‐A polycarbonate (PC) powder and its effect on the morphology of the sintered specimen.

Two sintering experiments, i.e. single‐spot laser sintering and raster‐scan laser sintering, were carried out and the material movement mechanisms were investigated in situ and subsequently by scanning electron microscopy.

During the raster‐scan laser sintering process, the movement of the powder was found to be primarily perpendicular to the scanning direction. When sintering at a high laser power, it significantly affected the surface morphology of the sintered specimens and parallel surface bands occurred along the scanning direction.

Experiments were carried out on a modified laser engraving machine rather than a commercial SLS machine.

A schematic model of the material movement mechanism for each of the sintering strategies is presented.

The results further the understanding of the sintering behaviour of the powder bed.

The aim of this research is to develop an eigenspace-based fuzzy c-means method for scalable topic detection.

The eigenspace-based fuzzy c-means (EFCM) combines representation learning and clustering. The textual data are transformed into a lower-dimensional eigenspace using truncated singular value decomposition. Fuzzy c-means is performed on the eigenspace to identify the centroids of each cluster. The topics are provided by transforming back the centroids into the nonnegative subspace of the original space. In this paper, we extend the EFCM method for scalability by using the two approaches, i.e. single-pass and online. We call the developed topic detection methods as oEFCM and spEFCM.

Our simulation shows that both oEFCM and spEFCM methods provide faster running times than EFCM for data sets that do not fit in memory. However, there is a decrease in the average coherence score. For both data sets that fit and do not fit into memory, the oEFCM method provides a tradeoff between running time and coherence score, which is better than spEFCM.

This research produces a scalable topic detection method. Besides this scalability capability, the developed method also provides a faster running time for the data set that fits in memory.

The purpose of this paper is to comparatively study the conventional, i.e. single magnet, and novel hybrid-magnet switched-flux permanent-magnet (HMSFPM) machines.

The HMSFPM machines utilize two magnet types, i.e. low-cost ferrites and NdFeB. Thus, a set of magnet ratios (?), defined as the quotient of the NdFeB volume to the total PM volume, is introduced. This allows any desired performance and cost trade-off to be designed. Series- and parallel-excited magnet configurations are investigated using 2-dimensional finite element analysis.

The torque of the HMSFPM machines is lower than the NdFeB SFPM machine but the flux-weakening performance is improved for similar machine efficiency. If the machine dimensions are unconstrained, the HMSFPM machines can have the same torque for reduced material costs and a moderate increase in machine dimensions. Ferrite SFPM machines have the lowest cost for the same torque but a significant increase in machine dimensions is required. Finally, the series-excited HMSFPM machine is the preferred over the parallel-excited HMSFPM machine because it has superior demagnetization withstand capability.

Mechanical and winding eddy current losses are not considered in the efficiency map calculations.

The NdFeB SFPM, ferrite SFPM, series-excited HMSFPM, and the parallel-excited HMSFPM machines are compared for their electromagnetic performance, flux-weakening, PM demagnetization, efficiency, and material costs.
