  Wichtig: The COVID-19 pandemic has forced people to limit their physical interactions, which has led to explosive growth in online grocery shopping. However, there is no clear consensus in the retailing literature on whether consumers prefer to buy groceries online. The objective of this current study is to synthesize research about online grocery shopping published before and during the COVID-19 pandemic and to develop a conceptual framework about online grocery purchase intentions and their determinants, the mediation effects of consumers' attitudes, the moderating effects of COVID-19, and control variables. The meta-analysis presents data derived from 50 independent samples with a sample size of 20,538 respondents. Selected determinants were identified as triggers for online grocery purchase intentions, and perceived usefulness and consumer attitude were identified as important mediators between determinants and intentions. The findings clarify the mechanisms behind the increase in online grocery shopping during the pandemic by presenting a decrease in the importance of its strongest determinants (i.e., perceived usefulness and attitude). Based on these findings, we present contributions to theory, managerial implications, and future research directions.

  Wichtig: Gambling opportunities are facilitated by the growth of the Internet and social media platforms. Digital games also increasingly include monetary features, such as microtransactions, blurring the line between gambling and gaming. The Internet provides a variety of virtual communities for gamblers and gamers, but comprehensive research on these communities and their relevance in gambling and monetary gaming behaviors remains scarce. This paper summarizes research of online gambling and monetary gaming communities based on a systematic literature review. A systematic literature search was conducted from five databases: Scopus, Web of Science, PsycINFO, Social Science Premium Collection, and EBSCOhost. The search was limited to empirical articles that focused on gambling or gaming involving money and examined online interaction between gamblers or gamers. Preliminary search resulted in 1056 articles, from which 55 were selected for the analyses based on pre-determined criteria. According to results, online communities serve different functions in gambling and gaming behaviors. Gambling communities are typically forums for discussing and sharing gambling experiences, strategies, and tips as well as gambling problems, while gaming communities are inherently embedded inside a game being an essential part of the gaming experience. Identification with virtual communities influences gambling behavior and monetary gaming behavior through mechanisms of perceived norms, social influence, and community feedback. Whereas some gambling communities may provide protection from excessive gambling habits, gaming communities seem to solely motivate gaming behavior and purchase intentions. The role of online communities should be acknowledged in prevention and treatment of gambling and gaming problems.

  Wichtig: The fermentation of food products is a transformation and preservation process in which different metabolites are generated, contributing to consumer health. In this sense, this systematic review aims to analyze the factors that guide the perception and preference for fermented foods. In addition, different perspectives are proposed based on the findings. The systematic search was carried out in four databases: Emerald Insight, Science Direct, Wiley Online Library, and Multidisciplinary Digital Publishing Institute. The keywords used were (Title/Abstract): fermented products, overall liking, purchase intention, expectations, emotions, interculturality, perception, and consumers. Ninety-two articles (n = 92) were selected and classified. The factors identified were (1) biological and physiological, (2) extrinsic product characteristics, (3) intrinsic product characteristics, (4) psychological, (5) situational, and (6) sociocultural. Intrinsic product characteristics were the most relevant, while the situational factors were the least studied. Our main contribution was a multidisciplinary approach to addressing the different factors in an integrated way, allowing a broader perspective of both products and consumers. This approach could help the reader understand consumer behavior and propose product improvements.
