The corrosive attack of boiler surfaces exposed to flue gases has occurred from time to time in plant operated by the Central Electricity Generating Board. The availability lost in this way is little more than 1% of the total boiler capacity installed, but when the load demand is met mainly by unit generators with a steaming capacity over 100 MW, the enforced shut‐down of one of these units would be a more serious loss. This article describes the ways in which various parts of boilers are attacked, the factors affecting corrosion in these cases and the chemical basis of the processes. Investigations are being carried out, and several preventive methods are mentioned.

The first part of this article, which appeared last month, listed the conditions which influence the occurrence and rate of boiler corrosion, and described the mechanisms of high‐temperature corrosion arising from various causes. In this, the second part, the problems of low‐temperature corrosion are discussed. The conditions affecting this phenomenon are given, and the causes of acid attack and blockage are discussed, the main problem being the formation of sulphur trioxide. Plant trials and counter‐measures in various countries are also described.

The usual method of analysis of product attributes in marketing is to fit a multinomial logit model within a stated choice experiment, to determine the impact of attributes on the choice probability, which is equivalent to market share. The market share is intuitive and is based on each single choice in the study. However, revealed preference allows for a study into repeat purchase and loyalty, which can also be rich constructs for determining consumer preference.

The authors introduce a loyalty measure, polarisation, and show results based on a wine data set of revealed preference. Polarisation is a function of the beta binomial distribution (BBD) and can also be a function of the Dirichlet multinomial distribution (DMD). The DMD provides a standardised or average loyalty effect for each attribute (such as wine variety), and the BBD an individual effect for each attribute level (such as cabernet) within the attribute. While the DMD results provide a rich “first‐pass” of the data, it is the individual results which can classify levels as reinforcing, niche, or change‐of‐pace in nature, with subsequent different marketing implications. These implications are drawn out in this study.

Specifically, the DMD results show higher loyalty towards price and variety rather than to region and brand. The BBD results show that segmented preferences in the wine market are influenced more by the price attribute levels and that the two key single varietals in the red wine category tend to behave as reinforcing attribute levels with important marketing implications for small and large wine brands.

The authors extend the work of stated choice experiments into the realm of actual consumer purchase behaviour for wine. They also find that consumers’ repeat purchasing is based on attributes other than brand. This provides a useful platform for both researchers to further investigate loyalty/repurchasing using attributes as well as for marketing practitioners to better position their products to consumers.

New Research Laboratory. The recently opened Passfield Research Laboratories at Passfield, Hants., will be devoted to combined research programmes for Metal Containers Ltd., the U.K. company, and Inland Steel Container Co., the U.S. company, and the work being undertaken is expected to lead to improved containers in steel, plastics and fibre materials and new steel/plastic and fibre/plastic packaging systems.

To measure the extent to which wine buyers behave differently when purchasing wine online vs in two brick and mortar stores. The article aims to extend the use of the Double Jeopardy principle and empirical-based methodology to the wine category in a European retailing context.

Customer loyalty data of two brick and mortar stores and the website orders of a Belgian retailer have been gathered for a one-year period. Data have been analysed based on three specific wine attributes: country of origin, grape variety and brand. Double Jeopardy measurements have been calculated for each of these attributes.

This study enlarges the scope of use of the Dirichlet principles. All three hypotheses derived from the Double Jeopardy patterns across all attributes are confirmed. From the perspective of these principles, we demonstrated that wine buyers do not behave differently in brick and mortar vs online stores.

Very few studies have analysed and understood wine buyers' behaviour using actual purchasing data from retail stores, and none have been released comparing online and brick and mortar stores owned by the same retail brand. From that perspective, our study demystifies the way people really buy, and confirms what has been found in other product categories.

BUILDING WITH ALUMINIUM. For over 60 years satisfactory service has been achieved in the building industry with aluminium components. Success has been apparent when the correct alloy has been correctly applied. However, examples of corrosion failure generally attract more attention than the smooth success stories. Such an example is embodied in a circular sent out last month by the Ministry of Housing and Local Government to local authorities concerning corrosion in certain types of aluminium bungalows. The circular follows an investigation by the Ministry and the Building Research Station.

Heavy corrosion resulted from the sulphur dioxide content, temperature and variation in relative humidity of the combustion gases in mild‐steel stacks, and replacement had been necessary after about two years' service. However, as this case history shows, such stacks can be free from corrosion and in excellent condition after many years' service.

This study aims to understand the market structure and explore the applicability of recognised generalisations to a European wine retail market. The study considers whether brands in European wine retailing follow the established double jeopardy and duplication of purchase laws, with the aim of investigating their limits so as to identify where market partitions are evident.

The researchers conducted a cross-purchasing analysis within the wine category over a 12-month period, using a customer panel of n = 25,000 across a chain of independent retail stores in an English-speaking European country. Analysis was conducted across purchases of the top 20 wine brands.

Consumer wine repurchase results confirmed a double jeopardy pattern. These consumers’ wine repurchasing behaviour from other top-20 wine brands could have generally been predicted in line with the duplication of purchase law. However, a small number of exceptions to these patterns were identified, suggesting the existence of market partitions.

In this study, market partitions were evident for selected brands, a wine region and a common grape variety, Sauvignon blanc. Such exceptions illustrate that consumer purchase patterns can deviate from predictions, for a small number of brands in a consumer goods category than would be expected given duplication of purchase law norms. Such anomalies to empirical generalisations help demonstrate boundary conditions and lead further research on the market conditions required for such anomalies to be evident. Implications suggest that further research should be conducted on the product features creating market partitions.

The findings suggest that regional wines can appeal to a more clearly partitioned customer group within the clientele, but that substitution is noted among brands within regions.

To the best of the authors’ knowledge, this is the first study to use a large sample consumer database to determine the generalisability of two well-established empirical generalisations: the double jeopardy and duplication of purchase laws, to the wine retail market. Knowing these are applicable to the wine retail markets allows wine producers and retailers to predict expected repurchase and cross-purchasing norms.

This study aims to identify the most important attributes that the consumer uses in the process of choosing wine, which can then be used by wine‐producing companies in marketing strategies.

The methodology consisted of a survey of 421 wine consumers using the best‐worst scaling methodology. Various consumer segmentations were made by gender, income and age groups.

The two main attributes that condition consumers in choosing wine are previous tasting and region of origin. The latter attribute is valued mainly by women and in general by consumers over 34 years old who have a net monthly family income above €1,500. The previously tasted attribute, which on many occasions is associated with the price attribute, is valued basically by men and particularly by younger consumers and those with lower incomes.

It must be pointed out that in the short term the basic strategy of wine‐producing enterprises from any given region of origin is to compete on price. However, in the long term increasing their prestige is all that remains to compete actively with the various regions of origin.

This paper contributes to a greater knowledge of Spanish consumer habits by analysing the most important wine attributes in the process of purchasing wine.

This paper aims to review and map the landscape of luxury wine consumption in multidisciplinary literature. It highlights the key themes of analysis, consumer markets and common behaviours of luxury wine consumption.

The paper analyses 85 articles on luxury wine consumption using Leximancer and content analysis.

Six main topics in the extant literature are identified as follows: product perception, wine price, wine information, consumption behaviour, group and China market. Our study revealed the shift in luxury consumption towards affordability, availability, middle-class, younger consumers and predominantly Asian markets.

As a follow-up to this research, empirical research on luxury wine consumption is needed to establish more precise definitions of terms.

Wine as a product is susceptible to social changes and preferences, positioning it between old and common luxury.

This research offers theoretical insights into research on luxury wine, including how the literature reflects recent societal changes. It also provides a roadmap for future research in this field.
