Abstract
Purpose
Food companies and consumers are increasingly interested in healthy food and beverages. Coffee is one of the most commonly consumed beverages worldwide. There is increasing consensus that coffee consumption can have beneficial effects on human body. This paper aims at exploring Twitter messages' content and sentiment towards health attributes of coffee.
Design/methodology/approach
The research adopted a utilitarian and hedonic consumer behaviour perspective to analyse online community messages. A sample of 13,000 tweets, from around 4,800 users, that mentions keywords coffee and health was collected on a daily basis for a month in mid-2017. The tweets were categorized with a term frequency analysis, keyword-in-context analysis and sentiment analysis.
Findings
Results showed that the majority of tweets are neutral or slightly positive towards coffee’s effects on health. Media and consumers are dynamic Twitter users. Findings support that coffee consumption brings favourable emotions, wellness, energy, positive state of mind and an enjoyable and trendy lifestyle. Many tweets have a positive perception of coffee health benefits, especially relating to mental and physical well-being.
Research limitations/implications
The high number of users and tweets analysed compensates the limited amount of time of data collection, Twitter messages' restricted number of characters and quantitative software analysis limitations.
Practical implications
The research provides valuable suggestions for food and beverage industry managers.
Originality/value
This work adds value to the literature by expanding scholars' research on food product attributes perception analysis by using social media as a source of information. Moreover, it provides valuable information on marketable coffee attributes.

Abstract
Purpose
Combining sensory evaluations and hypothetical valuation mechanisms, this study aims to investigate the impact of consumers' product sensory attributes on willingness to pay (WTP) and overall liking for a new apple cultivar.
Design/methodology/approach
A sample of non-expert participants (n = 122) evaluated the overall liking and just-about-right (JAR) attributes. A variable transformation approach was applied to make linear and interval regression models between the JAR attributes, overall liking scores and participants' WTP.
Findings
The study reveals the high consumer appreciation for the new apple in both hedonic and economic terms. After controlling the anchoring effect's bias, the predicted mean WTP for the new apple cultivar was €3.26 per kilogramme. Crunchiness and flavour significantly affect both participants' overall liking and WTP.
Research limitations/implications
The main limitation is the non-probabilistic sampling procedure, which does not allow for the generalisation of the results. Penalty analysis for JAR attributes in monetary and hedonic terms is beneficial for optimising the product and evaluating its potential in the marketplace.
Practical implications
The findings provide helpful directions for product optimisation in future breeding programmes to ensure the long-term sustainability of the new apple cultivars in the marketplace.
Originality/value
This study provides evidence of the beneficial synergy of mixing sensory-oriented research with the behavioural economics field of study.

Abstract
The religious tradition of male circumcision has come increasingly under attack across a number of European states. While critics of the practice argue that the problem is about children’s rights and the proper relationship between secular and religious traditions, Jews tend to see these attacks within the longer history of attempts to assimilate and remake them according to the norms of the majority. Using the 2012 German legal controversy concerning the issue as my vantage point, I explore how contemporary criticism of male circumcision remains entangled with ambivalence toward Judaism and the Jews as the “other.” Through a close reading of the arguments, I show how opponents use the seemingly neutral language of universal human rights to (re)make Jewish difference according to the norms of the majority. I conclude by arguing that such an approach to this issue runs the risk of turning Jews once again into strangers at a time when cultural anxieties are troubling European societies.

Abstract
Purpose
The purpose of this paper is to perform an integrative analysis, mapping the main areas of the celebrity endorsement literature of the last 20 years, offering a taxonomy of subject subareas and a research agenda for the topic.
Design/methodology/approach
The research was divided into two stages: the first was a systematic review of literature, and the second consisted on complementary information based on the generation and analysis of the maps elaborated by the VOSviewer software based on the data collected. The searches for the data occurred between the months of January and March of 2017.
Findings
The paper provides a decentralization framework in terms of authors regarding the celebrity endorsement. The country with the largest number of research works in the area is the USA; also, the paper reveals the most cited document, also the main journals about the theme, the main keywords, the main authors and their discussions. Thereafter, the paper presents tables containing the main author’s and respective theme inside celebrity endorsement.
Research limitations/implications
One possible limitation of the research is that it was performed only in the Scopus database, and it may be suggested as future searches that other databases are included as well.
Practical implications
The results of this paper can serve as a facilitating guide for researchers and for managers that want to know more about the topic.
Originality/value
A categorization table was proposed containing the subthemes of celebrity endorsement that were discussed in the last 20 years and a list of their respective authors, including the following subjects: cultural comparison, congruence, adverse effects, efficacy and intention to purchase, marketing destinations, social media, models and reviews, multiple endorsements, social policy, values of brand/economic.
