Impacts of Covid-19 on peer-to-peer accommodation platforms: Host perceptions and responses.

The Covid-19 pandemic has brought international tourism at a standstill. Peer-to-peer (P2P) accommodation, in particular, has been greatly affected with platforms being heavily criticised for lacking a strategic response to users' needs. Drawing from semi-structured interviews with P2P accommodation hosts, this study aims to explore: a) their perceptions of the short-term impacts of the pandemic on their hosting practice, b) their responses to the pandemic and c) their perceptions of the long-term impacts of the pandemic on the P2P accommodation sector. The study offers a continuum of host pandemic responses which illustrates different types of hosts in relation to their market perspective and intention to continue hosting on P2P platforms. The continuum carries theoretical implications as it offers insights to academics exploring crisis impacts on P2P accommodation. It is also of practical value to platforms and practitioners as it may lead to improved crisis management strategies.

Probiotics: Versatile Bioactive Components in Promoting Human Health.

The positive impact of probiotic strains on human health has become more evident than ever before. Often delivered through food, dietary products, supplements, and drugs, different legislations for safety and efficacy issues have been prepared. Furthermore, regulatory agencies have addressed various approaches toward these products, whether they authorize claims mentioning a disease's diagnosis, prevention, or treatment. Due to the diversity of bacteria and yeast strains, strict approaches have been designed to assess for side effects and post-market surveillance. One of the most essential delivery systems of probiotics is within food, due to the great beneficial health effects of this system compared to pharmaceutical products and also due to the increasing importance of food and nutrition. Modern lifestyle or various diseases lead to an imbalance of the intestinal flora. Nonetheless, as the amount of probiotic use needs accurate calculations, different factors should also be taken into consideration. One of the novelties of this review is the presentation of the beneficial effects of the administration of probiotics as a potential adjuvant therapy in COVID-19. Thus, this paper provides an integrative overview of different aspects of probiotics, from human health care applications to safety, quality, and control.
