The deployment of Blockchain technology in the tourism industry is already becoming a reality with the gradual emergence of innovative business models. At its core is the promise of improving the efficiency of the tourism service value chain and enhancing the quality of the service provided to the end customer. This paper analyses research trends focused on using Blockchain technology in tourism. The aim is to determine how this technology impacts the tourism sector and its sustainability. A systematic review, descriptive bibliometric analysis, and network analysis based on co-authorship, co-citation, and keyword analysis criteria, among others, have been used. The results reveal that the subject matter analysed is generating a growing trend in academic research in the fields of sustainable management and supply chain efficiency. The activities in the tourism sector that are incorporating this technology to a greater extent are those related to the areas of marketing, logistics, and smart business models, according to the data extracted from the analysis. This technology already enables the application of solutions that predict and promote tourist behaviour based on sustainable behaviour and consumption habits, generating value for the different stakeholders.

Purpose: Working in virtual teams and realizing projects through ICT tools has become the usual way of collaboration, especially across knowledge workers. Therefore this paper has two research objectives. The first objective is to verify to what extent the virtuality level is correlated with knowledge sharing behaviors. The second objective is to verify to what extent methods of management projects are correlated with knowledge sharing behaviors in virtual teams. Methodology: To achieve research objectives empirical research was conducted. Based on the previous research, the online survey was designed. The survey was filled out by 336 members of virtual teams. They worked using ICT tools and realize technology projects in the IT industry. Collected data were analyzed by IBM SPSS Imago Pro to test hypotheses. Findings: The correlation between the level of virtuality and knowledge sharing behaviors did not confirm. The hypothesis that methods of project management are correlated with knowledge sharing behaviors in virtual teams was partly supported. Research limitations: Research was conducted in technology teams in the IT industry. Virtual team members only from European companies have taken part in the research. Practical implications: Results can be useful to manage virtual teams not according to overall beliefs but scientific evidence. Based on the results it is possible to identify which variables for knowledge sharing behaviors in virtual teams are significant and which are not. Originality/value: Only a few studies have explored knowledge sharing in a virtual context. This paper supports scientific evidence of the level of virtuality and methods of managing projects concerning knowledge sharing behaviors as not discovered in earlier research. Keywords: virtual teams, knowledge sharing behaviors, project management, virtual management, post-COVID era.

This article concerns work in dispersed teams, and particularly the sharing of leadership tasks through members of such teams. The research tool created on the scientific literature was presented (questionnaire). This tool was used in the pilot study, which covered 5 teams of various degrees of dispersion, formed by 47 people. The results of the study made it possible to conclude that knowledge sharing is the most shared leadership task. Moreover, a correlation between the degree of shared leadership tasks and the degree of team dispersion was discovered

STRESZCZENIEW artykule opisano w kilku aspektach realizowanie przez przedsiębiorstwa prac badawczo-rozwojowych. W pierwszej kolejności odwołano się do aktów prawnych, które defi niują prace badawczo-rozwojowe, określają ich rodzaje oraz zakres. Następnie odniesiono się do pojęcia Centrum Badawczo-Rozwojowego, ponieważ w podejściu biznesowym jest ono stosowane częściej i szerzej niż w ujęciu formalno-prawnym. Część analiz poświęcono aktualnej dystrybucji środków fi nansowych Unii Europejskiej przeznaczanych na tworzenie i rozbudowę infrastruktury Centrum Badawczo-Rozwojowym. Zaakcentowano jednocześnie duży wpływ tych środków na obecną sytuację, co bardzo dobrze odzwierciedlają dane statystyczne. Ostatnia część artykułu wskazuje na przyczyny i skutki podejmowania decyzji o realizacji prac badawczo-rozwojowych oraz ich wpływ na sposób funkcjonowania przedsiębiorstw.Słowa kluczowe: Centrum Badawczo-Rozwojowe, prace badawczo-rozwojowe, środki Unii Europejskiej, fi nanse przedsiębiorstwa * Adres
