To examine the relationship between online comments, merchant replies and online sales of tourism products and focus on the moderating role of tourist destination.

This article uses crawler technology and regression analysis methods.

The researchers found the following: (1) The number of pictures uploaded with online comments, the number of merchant replies and the length of merchant replies have a significant positive effect on sales of tourism products, while the length of comments and the similarity of merchant replies negatively affect sales of tourism products. The emotional scores of the reviews do not significantly affect sales of tourism products. (2) Tourist destination moderates the relationship between user comments and sales of tourism products. The length of comments has a greater negative effect on sales of domestic tourism products, while the number of comments has a greater positive effect on sales of overseas tourism products. (3) Tourist destination moderates the relationship between merchant replies and sales of tourism products. Consumers who choose domestic tourism products pay more attention to the interactivity reflected by merchant replies (e.g. number and length of merchant replies), while consumers who choose overseas tourism products hope to receive replies that are more useful, such as reply similarity.

The research conclusions enrich the relevant research in the field of online review research and has practical significance for how companies increase sales of tourism products.

Online reviews are regarded as a source of information for decision-making because of the abundance and ready availability of information. Whereas, the sheer volume of online reviews makes it hard for consumers, especially the older adults who perceive more difficulties in reading reviews and obtaining information compared to younger adults, to locate the useful ones. The main objective of this study is to propose an effective method to locate valuable reviews of mobile phones for older adults. Besides, the authors also want to explore what characteristics of the technology older adults prefer. This will benefit both e-retailers and e-commerce platforms.

After collecting online reviews related to mobile phones designed for older adults from a popular Chinese e-commerce platform (JD Mall), topic modeling, term frequency-inverse document frequency (TF-IDF), and linguistic inquiry and word count (LIWC) methods were applied to extract latent topics and uncover potential dimensions that consumers frequently referred to in their reviews. According to consumers' attitudes towards different popular topics, seven machine learning models were employed to predict the usefulness and popularity of online reviews due to their excellent performance in prediction. To improve the performance, a weighted model based on the two best-performing models was built and evaluated.

Based on the TF-IDF, topic modeling, and LIWC methods, the authors find that older adults are more interested in the exterior, sound, and communication functions of mobile phones. Besides, the weighted model (Random Forest: Decision Tree = 2:1) is the best model for predicting the online review popularity, while random forest performs best in predicting the perceived usefulness of online reviews.

This study’s findings can help e-commerce platforms and merchants identify the needs of the targeted consumers, predict reviews that will get more attention, and provide some early responses to some questions.

The results propose that older adults pay more attention to the mobile phones' exterior, sound, and communication function, guiding future research. Besides, this paper also enriches the current studies related to making predictions based on the information contained in the online reviews.

To propose a model of a privacy‐enhanced catalogue search system (PECSS) in an attempt to address privacy threats to consumers, who search for products and services on the world wide web.

The model extends an agent‐based architecture for electronic catalogue mediation by supplementing it with a privacy enhancement mechanism. This mechanism introduces fake queries into the original stream of user queries, in an attempt to reduce the similarity between the actual interests of users (“internal user profile”) and the interests as observed by potential eavesdroppers on the web (“external user profile”). A prototype was constructed to demonstrate the feasibility and effectiveness of the model.

The evaluation of the model indicates that, by generating five fake queries per each original user query, the user's profile is hidden most effectively from any potential eavesdropper. Future research is needed to identify the optimal glossary of fake queries for various clients. The model also should be tested against various attacks perpetrated against the mixed stream of original and fake queries (i.e. statistical clustering).

The model's feasibility was evaluated through a prototype. It was not empirically tested against various statistical methods used by intruders to reveal the original queries.

A useful architecture for electronic commerce providers, internet service providers (ISP) and individual clients who are concerned with their privacy and wish to minimize their dependencies on third‐party security providers.

The contribution of the PECSS model stems from the fact that, as the internet gradually transforms into a non‐free service, anonymous browsing cannot be employed any more to protect consumers' privacy, and therefore other approaches should be explored. Moreover, unlike other approaches, our model does not rely on the honesty of any third mediators and proxies that are also exposed to the interests of the client. In addition, the proposed model is scalable as it is installed on the user's computer.

The conclusions of studies on the factors correlated with the perceived usefulness of online reviews are inconsistent due to differences in research perspectives, research objects, research methods and data types. This study conducted a meta-analysis to verify a proposed model of perceived usefulness to obtain general conclusions.

A meta-analysis was conducted to study the factors correlated with the perceived usefulness of online reviews based on 51 studies.

The results indicate that, with the exception of negative reviews, the order of relevance for the perceived usefulness of online reviews is as follows: the trust tendency of review readers, review replies, review depth, review pictures, reviewer trustworthiness, positive reviews, reviewer expertise, review time and reviewer information disclosure. Perceived usefulness was significantly positively correlated with purchase intention. Review time, positive reviews and negative reviews were also more significantly correlated with perceived usefulness for search products than for experiential products. Review depth, reviewer trustworthiness, reviewer expertise and purchase intention had greater positive correlations with perceived usefulness for experiential products than for search products.

This study proposes an extended information adoption model based on argument quality and source credibility. The model includes personal factors such as the trust tendency of review readers, constructs a theoretical model of the factors correlated with the perceived usefulness of online reviews and considers the moderating effects of product type.

The purpose of this paper is to understand differences between open-book accounting (OBA) using static prices and OBA using dynamic prices. The authors identify how these differences influence various aspects of customer–supplier relationships.

This paper is based on a case study involving a builders’ merchant and a wood manufacturer in the UK. The builders’ merchant under discussion has recently outsourced part of its production to the aforementioned wood manufacturer by using OBA with dynamic prices. For this case study, the authors have conducted interviews with multiple people from both parties in the agreement. Additional illustrative cases are provided through a study of other qualitative papers on OBA.

The authors find evidence supporting that, when dynamic prices are used in OBA, risk (unpredictability) is shifted from the supplier to the customer. Also, the customer frequently focuses on the supplier’s costs, both parties often aim for a long-term relationship and the customer becomes more dependent on the supplier, causing high interdependence. Furthermore, empirical evidence suggests that the customer finds price less important, and the reallocation of activities between the customer and supplier is easier in OBA setups in which dynamic prices are used.

This paper provides the first study of how differences between dynamic and static prices in OBA influence the customer–supplier relationship. This paper adds to the developing literature on OBA, in particular, as well as to literature on pricing, in general.

In the context of increased interest in the sustainability of food supply chains, this paper aims to assess perceptions of the relative importance of economic, social and environmental factors as they influence decision making by growers, merchants and retailers, using fresh potatoes in Britain as a case study.

Following exploratory interviews with key informants, a two‐staged survey of 240 potato growers, 17 potato merchants, and four retailers was carried out to assess perceptions of sustainability. Data analysis used a range of non‐parametric statistical methods.

Economic and related market factors associated with staying in business and maintaining competitive advantage were the dominant concern for all supply chain participants. Greater importance, however, is now given to social and environmental factors both as influences on decision making and as indicators of business performance. The social capital of the supply chain, as it describes relationships amongst participants, is an important moderator of business uncertainty. Environmental performance, measured in terms of the use of natural resources and the risk of pollution, is driven by a mix of compliance requirements and perceived market drivers.

This research design was constrained by limited access to objective verifiable quantitative data, in part due to commercial confidentiality.

This paper confirms the relevance of sustainability criteria to measure and report supply chain performance.

This paper measures perceptions of sustainability as it affects business decisions in the supply chain. It confirms the need for a set of objectively verifiable indicators to guide and report supply chain performance.

This paper aims to examine how consumers’ perceptions of artificial intelligence (AI) chatbots influence individuals’ cognitive and emotional states and their subsequent behavioural intentions vis-à-vis online travel agencies (OTAs).

The survey sample comprised 566 customers who had experienced the use of travel AI chatbots in China using a combination of online and offline questionnaires. Partial least squares structural equation modelling was used to test the hypotheses.

The results revealed that interaction and information quality, as AI chatbot stimuli, significantly increase potential tourists’ trust and purchase intention. Perceived usefulness plays a mediating role in the relationship among interactivity, information quality, customer trust and purchase intention. Furthermore, the findings indicated that customers with high product familiarity exhibited greater trust in products demonstrating a high level of perceived usefulness.

By integrating cognitive consistency theory, this study theoretically validates the applicability of the stimulus–organism–response framework on AI chatbots and provides academics with useful insights regarding the influence mechanisms of human–computer interaction and information quality on customer response within OTA settings.

Highlights product development problems in the UK and suggests the UK has brilliant design skills, but poor processes and is therefore unable to translate design into goods. Describes the view of Sheridan Tatsuno (principal of NeoConcepts) at a recent conference, discusses the future of design as regards concurrent engineering (CE), humanware engineering (HE), human‐computer interface (HCI) and the shift to user‐centric innovation. Examines designs by Britain, Kenneth Grange (consultant product designer) who suggests the reason for the schism between the maker and the merchant in the UK is due to the assembly side of the industry being traditionally less well funded. Concludes UK designers are some of the best in the world but UK companies are the slowest to use this home‐grown talent.

The Department of Scientific and Industrial Research has released an account of the preparation of emergency rations in the form of dehydrated foodstuffs. These rations were designed and made when the result of a forced landing of an aircraft flying over polar regions may have to be faced. Having regard to the special circumstances for which the method described by the Department was designed it is perhaps not too much to say that it introduces as great a change in feeding the crews of airships as did Appert in feeding the crews of sailing ships a hundred and thirty‐five years ago. Appert's method did much to eliminate scurvy. This to prevent starvation and loss of life which the accounts of Polar expeditions have too often recorded. Dried fruits and dried vegetables have long been known and used. Milk powder and egg powder are now as well known. If these and tinned foods be regarded as ordinary rations they are too heavy and too bulky to be of use in an emergency such as may arise when a Polar flight ends in an unpremeditated grounding and the crew are left in a Polar desert to make the best they can of the conditions. It will be remembered that in May last the “Aries,” a British Lancaster airship, made a trip of some 17,000 miles. Much of this trip was in the Polar regions. The g eographical North Pole was visited and in the return journey the true position of the magnetic North Pole was ascertained in a 4,000 mile non‐stop return journey from White Horse, Yukon, to Shrewsbury. In view of possibilities an emergency ration had to be designed in which most of the food was in the form of hydrostatically compressed blocks of compounded and dehydrated foods. The compression reducing bulk; dehydration, weight; compounding ensuring variety. The rations so prepared had to be sufficient to feed nine men for twenty‐eight days. An account of the rations so prepared forms the subject of the report issued by the Department. These blocks consist of mixtures of dehydrated foods with added sweetening and flavouring materials where appropriate, so that each is a ready‐made meal requiring only the addition of water. They are fabricated into tablets of standard size (usually 2in. by 2in. by 0·9in.). They need only to be wrapped in high grade waxed films or papers and their standard size facilitates the assembly of mixed rations whilst very little space is wasted as compared for instance with circular cans. They are made by one of two processes—those containing dried foods of large particle size such as dehydrated meat or vegetables are made by compressing the mixture in a hydraulic press. The pressed block can be broken down easily in the hand. Where the particle size of the material is much finer, as with spray dried powders such as milk or egg, such compressed blocks would be very difficult to crumble, and furthermore lumps escaping crumbling would remain as unreconstituted lumps and mar the smoothness of the product. Thus they are prepared by casting the mixture hot into moulds with added molten fat. The block can be dissolved by boiling water. Many of the blocks containing milk powder may be eaten as sweets. Four kinds of menus from these blocks were prepared to relieve monotony of diet. Details of these are given in the report for four days. The total number of calories for each day ranges from 3,550 to 3,380. The weight of food per man in grammes from 715 to 704. Fat in grammes 213 to 177. Percentage of fat 30 to 25. The computed total nett weight was 393 lbs. Rations for two days can be packed in a standard four‐gallon can—gas packed if necessary—as a master container. Fourteen such cans would be necessary. These, together with immediate wrappings, would make a gross weight of 435 lbs. A most important consideration is weight. It is pointed out that the water extracted during the dehydration process would fill another seventeen cans! If light metal alloys instead of tin plate were used for the master cans a reduction of weight would be possible, but even a total weight of 435 lbs. is “very modest” compared with the weight of most emergency rations, even when the weight of master containers is excluded for the rations as drawn up provide for each man three normal meals per day. The Department refers to the theoretical aspect of the provision of a calorific level of 3,400 per day, with a total weight of 704 gms. per man. If the diet were made up of pure carbohydrate, pure fat and pure protein alone, then, using the factors 4·9 and 4 respectively as the number of calories derived from each gramme of food, a diet containing 25 per cent. fat would have an overall calorific value of 5·25 Cals/gm. a diet giving 3,400 calories, as in Day 3, would therefore weigh 647 gms. This is an absolute minimum below which it would be impossible to go. This figure takes no account of the residual water content of dehydrated foods of salt or minerals or roughage. The weight of 715 gms. achieved in practice includes, in addition to water and roughage, some 8 gms. of salt and 13 gms. of tea. It is therefore considered that, for a ration which gives three normal meals a day, it would be virtually impossible with the materials available at present to reduce the weight of the ration further. It may be added that a stove has been designed to burn motor spirit should it be possible to salvage any after a forced landing. It is considered that this type of food may be of great value for future polar expeditions. This is undoubtedly true whether aeroplanes be used as part of the equipment or not. It may be permissible to suggest that rations such as these would prove useful in land expeditions at a pinch. While in the case of a ship having to be abandoned in mid ocean the crew's chance of survival would obviously be bettered by having a supply of such concentrated rations in the ship's boats.

The purpose of this paper is to argue that free market capitalism is neither efficient nor just. This is in spite of the claims made by its proponents who, utilizing Adam Smith's doctrine of invisible hand or the fundamental theorem of welfare economics, assume that it is efficient, just, smooth functioning, and self‐regulating.

The paper utilizes conceptual/theoretical research and arguments that have emerged in the literatures of public economics and welfare economics.

In addition to proving the above, the paper also finds that Adam Smith is actually a moral egalitarian, thus he could not have agreed with Nozick and Friedman regarding the nature of capitalism. To the extent that Smith supported free market capitalism, it was because he thought, in contrast to mercantilist policies, that free markets would lead to equity and justice.

The paper is an original/valuable contribution since it rescues Adam Smith from the extreme proponents of laissez‐faire capitalism who claim him.
