With ageing, there is a greater risk of dehydration. This study investigated the diuretic effect of alcoholic beverages varying in alcohol concentration in elderly men. Three alcoholic beverages (beer (AB), wine (AW), and spirits (S)) and their non-alcoholic counterparts (non-alcoholic beer (NAB), non-alcoholic wine (NAW), and water (W)) were tested in a diet-controlled randomized crossover trial. For the alcoholic beverages, alcohol intake equaled a moderate amount of 30 g. An equal volume of beverage was given for the non-alcoholic counterpart. After consumption, the urine output was collected every hour for 4 h and the total 24 h urine output was measured. AW and S resulted in a higher cumulative urine output compared to NAW and W during the first 4 h (effect size: 0.25 mL p < 0.003, effect size: 0.18 mL, p < 0.001, respectively), but not after the 24h urine collection (p > 0.40, p > 0.10). AB and NAB did not differ at any time point (effect size: -0.02 mL p > 0.70). For urine osmolality, and the sodium and potassium concentration, the findings were in line. In conclusion, only moderate amounts of stronger alcoholic beverages, such as wine and spirits, resulted in a short and small diuretic effect in elderly men.

In het artikel "Waarom hebben sociale robots in de supermarkt (nog) geen succes als wijnadviseur?" (Hindriks et al., 2024) onderzochten Koen Hindriks, Stephanie van de Sanden, Merle Reimann, Jesper van de Graaf, Nina van Gulik, Jacqueline Arnoldy, Ewout Nas, Filip Otten en Tibert Verhagen de inzet van een sociale robot voor wijnadvies in een Jumbo-supermarkt. Gedurende drie weken werd een Pepper-robot naast het wijnschap geplaatst om klanten te helpen bij hun keuze. Hoewel klanten die de robot gebruikten overwegend positief waren over zijn betrouwbaarheid en nut, bleek uit observaties dat slechts een klein deel van de wijnkopers de robot daadwerkelijk inzette. De onderzoekers noemen drie verklaringen: klanten zijn nog onvoldoende bekend met het doel van de robot, de schaal en snelheid van supermarktbezoek beperken de behoefte aan advies, en wijn is een hedonistisch product waarbij consumenten liever menselijk advies krijgen. Toch zien de auteurs mogelijkheden, vooral in grotere supermarkten met een breder assortiment, mits de robot beter aansluit bij het natuurlijke keuzeproces van klanten, bijvoorbeeld door gebruik van klantbeoordelingen of expertscores. Verdere ontwikkeling met behulp van AI-chatbots biedt volgens hen perspectief voor toekomstig, persoonlijker advies.

We designed a wine recommendation robot and deployed it in a small supermarket. In a study aimed to evaluate our design we found that people with no intent to buy wine were interacting with the robot rather than the intended audience of wine-buying customers. Behavioural data, moreover, suggests a very different evaluation of the robot than the surveys that were completed. We also found that groups were interacting more with the robot than individuals, a finding that has been reported more often in the literature. All of these findings taken together suggest that a novelty effect may have been at play. It also suggests that field studies should take this effect more seriously. The main contribution of our work is in identifying and proposing a set of indicators and thresholds that can be used to identify that a novelty effect is present. We argue that it is important to focus more on measuring attitudes towards robots that may explain behaviour due to novelty effects. Our findings also suggest research should focus more on verifying whether real user needs are met.

MoneyLab is a network of artists, activists, and geeks experimenting with forms of financial democratization. Entering the 10th year of the global financial crisis, it still remains a difficult yet crucial task to distinguish old wine from its fancy new bottles. The MoneyLab network questions persistent beliefs, from Calvinist austerity, growth, and up-scaling, to trustless, automated decision making and (anarcho-)capitalist dreams of cybercurrencies and blockchained solutionism.We consider experiments with digital coops, internet-based payment and network-based revenue models as spaces of political imagination, with an equally important aesthetic program. In this second MoneyLab Reader the network delves into topics like the financialization of art; love as a binary proposition on the blockchain; the crowdfunding of livelihood; the cashless society; financial surveillance of the poor; universal basic income as the real McCoy or a real sham; the cooperative answer to Airbnb and Uber; the history of your financial dashboard; and, Hollywood’s narration of the financial crisis. Fintech rushes through our veins, causing a whirlwind of critical concepts, ideas and imaginaries. Welcome to the eye of the storm.

In this article, the main question is whether and, if so, to what extent online journalism raises new moral issues and, if any, what kind of answers are preferable. Or do questions merely appear new, since they are really old ones in an electronic wrapping, old wine in new bottles? And how does journalism deal with the moral aspects of online journalism? The phenomenon of the Internet emerged in our society a few years ago. Since then, a large number of Dutch people have gone online, and the World Wide Web is now an integral part of our range of means of communication. Dutch journalism is online too, although certainly not in the lead. More and more journalists use the Internet as a source, especially for background information. Newspapers have their web sites, where the online version of the printed paper can be read. And that is it for the time being. There are no more far-reaching developments at present, certainly not on a large scale. Real online journalism is rather scarce in the Netherlands. The debate concerning the moral aspects of online journalism is mainly being conducted in the United States. First of all, by way of introduction, I will present an outline of online journalism. The first instance is the online version of the newspaper. Here, only to a certain degree new issues come up for discussion, since the reputation of reliability and accuracy of the papers, in spite of all criticism, also applies to their online versions. Besides, especially in the United States and increasingly in European countries as well, there is the so-called dotcom journalism, the e-zines, the online news sites without any relationship with printed newspapers. This may be the reason why these sites do not have a strong commitment to moral standards, at least as they have developed in the journalistic culture of the newspapers. After having outlined the moral issues arising in online journalism, the question will be addressed whether and, if so, to what extent it is meaningful and desirable to develop instruments of self-regulation for this new phenomenon of journalism.

Some sectors emphasize their tradition, such as beer, whiskey and wine, and other sectors pride themselves on continuous innovation in order to achieve ever better quality, such as detergent producers and (high) tech. Needless to say, both sides of the marketing strategy spectrum - tradition or continuous quality improvement - are in fact selling nonsense ...

The purpose of the research we undertook for this Conference Paper was to investigate whether marketing campaigns for specific types of drinks could be directed towards age cohorts rather than towards intercultural differences between countries. We developed consumer profiles based on drinking motives and drinking behavior by age cohorts. We hypothesized that differences between countries in the youngest age groups are smaller than in the older age groups, where country specific tradition and culture still plays a more prominent role. We, therefore tested, from the data obtained by the COnsumer BEhaviouR Erasmus Network (COBEREN), the hypothesis that the extent to which the age specific profiles differ between countries increases with age. The results confirm our hypothesis that the extent to which drinking motives differ between countries increases with age. Our results suggest that marketing campaigns which are directed towards drinking motives, could best be tailored by age cohort, in particular when it concerns age group 18-37 and more particular for beer, spirits and especially premix drinks. Marketing campaigns for non-alcoholic beverages should be made specific for the British countries and the Western countries, but even more effectively be made specific for the age cohort 18-37.

Le chevalier delibere (1483) by Olivier de la Marche has an extensive hermit scene: the hermit receives the author, Acteur, gives him food and drink and instructs him in the important issues of life. Le chevalier delibere thus stands in two main Western European literary traditions: stories about hermits as such (who do or do not provide travellers with food and shelter) and stories in which food and drink have an allegorical function. This paper will discuss both traditions, without attempting to cover all hermit stories or all allegories about food and drink.
