Against the background of the I50 paradigm, this paper queries in what ways blockchain and blockchain-based applications deployed in the smart city context facilitate the integration of the I50 paradigm in smart urban contexts.

A mixed methods approach is applied. First, by means of desk research and thematic literature review, a conceptual model integrating the I50 paradigm, smart city and blockchain-based solutions is built. Second, science mapping bibliometric analysis (SciMat) based on keywords’ co-occurrence is applied to a sample of 491 research articles to identify key domains of blockchain-based applications’ use in smart city. Third, a semi-systematic literature review complements insights gained through SciMat. Fourth, the findings are interpreted through the precepts of the conceptual model devised earlier.

The key blockchain-based applications in smart cities pertain to two domains, i.e. the foundational, service facilitation-oriented domain, including security (and safety), networks, computing, resource management and the service delivery-oriented domain, including mobility, energy and healthcare. Blockchain serves as the key building block for applications developed to deliver functions specific to each of the thus identified domains. A substantial layering of blockchain-based tools and applications is necessary to advance from the less to the more complex functional domains of the smart city.

At the conceptual level, the intricacies of the (making of the) I50 paradigm are discussed and a case for I50 – smart city – blockchain nexus is made. Easton’s input–output model as well as constructivism is referenced. At the empirical level, the key major domains of blockchain-based applications are discussed; those that bear the prospect of integrating the I50 paradigm in the smart city are highlighted. At the methodological level, a strategic move is made aimed at restoring the literature review’s role as subservient to the key line of exploration, to justify and ultimately support it, rather than to showcase the literature review as the ultimate purpose for itself.

This article aims to review critical thinking (CT) as a future skill in business.

The study employed two research methods: science mapping analysis based on bibliometric keyword co-occurrence data and systematic literature review following PRISMA guidelines. The application of two distinctive research methods meant that we could obtain a broad picture thematic overview as well as a detailed, fine-grained insight into the content of CT business research.

Research in CT in business studies is dominated by themes related to education, university and learning that far outweigh CT business application, which focuses on three research axes. These are specific business functions (e.g. accounting, marketing, human resources and identifying business opportunities), certain skills used in business (e.g. decision-making and creativity) and other business-related topics (including ethics, stakeholder relations and individual employee performance).

The article identifies new research gaps related to the link between CT and business performance, a firm’s ability to innovate and company characteristics. Moreover, the article highlights that CT positively influences business decision-making under the influence of cognitive biases and heuristics.

The article provides the first literature review on CT in business research. It uses a novel method of science mapping analysis to show unbiased algorithmic-based insight into the structure of the research, followed by a systematic literature review.

This chapter applies science mapping analysis (SciMat) and literature review as research methods to examine literature about higher education institutions (HEIs) during the Covid-19 pandemic. User acceptance, satisfaction, and perception are identified as the most productive research themes in the sample of 561 Web of Science (WoS) indexed articles about HEIs during the pandemic. The literature review of the top themes reveals that user acceptance is influenced by the perceived usefulness of online learning and ease of using online tools. The level of satisfaction among students in online learning is relatively high and linked with the perceived benefits of online courses. Conditions influencing user acceptance and perceived satisfaction differ between students and lecturers. Technology-related themes appeared to be relatively under-researched as standalone themes, but technological aspects turned out to be important components of the most prolific research themes identified.

This chapter uses multiple research methods, including quantitative science mapping analysis (SciMat) and a qualitative literature review, to provide insight into the academic debate unfolding at the intersection of big data and business processes. SciMat analysis based on keyword co-occurrence enabled identifying 12 of the most productive research themes, as reflected in a poll of 301 articles about big data and business processes. The three most important themes are: firm performance, Industry 4.0, and innovation. The traditional literature review on firm performance indicated that big data analytics (BDA) positively influence business process performance and have a beneficial impact on a firm’s performance, that is, the role of big data is viewed as critical in the context of Industry 4.0 because it enhances productivity and improves business processes. The benefits of BDA can be achieved only if the organizational obstacles related to planning, workforce attitude, and alignment with strategy are overcome. Moreover, big data is perceived as a significant source of innovation in an organization and can be conceptualized with the use of a resource-based view (RBV) of the firm. BDA positively influence business processes, which is strengthened by adequate implementation and openness to innovation.

Big data is a buzzword of our times, and yet the awareness of what big data is, how it permeates our daily lives, and how it is applied either in the policy-making process or in the business sector remains relatively low. From a different perspective, while specialists, that is, practitioners and researchers, dealing with the technical facets of big data successfully uncover new features, new domains, and new opportunities related to big data, there is a need of evaluating and examining these findings through the lens of social sciences and management. This chapter offers an insight into key issues and developments that shape the broad and multi-directional big data debate. To this end, the content of the book is elaborated and the key findings are highlighted. In this way, this chapter serves as a very useful guide into the question of how big data is applied across issues and domains and how it is valid and relevant to all of us today.

Institutions, including higher education institutions (HEIs), may use crises as an opportunity to develop, to transform and to improve their institutional resilience. Indeed, the Covid-19 pandemic proves that a vast majority of HEIs around the world effectively adapted to the circumstances of the pandemic and successfully embarked on remote learning. The analysis of HEIs proves as well that the nearly overnight switch to remote learning was but one aspect of the quiet transformation that HEIs worldwide were subdued to. In this context, this chapter identifies the administrative practices, including talent management, operations management, and above all, the organizational culture. The notion of changed expectations on the part of the faculty and the students is highlighted. The key point that this chapter makes is that the faculty and the art of education, rather than simply teaching, need to be placed first if HEIs are to retain their resilience.

The purpose of this study is to investigate the factors affecting supplier selection in food and beverage divisions in the Greek hotel industry. This research aimed to (1) examine the factors affecting supplier selection in food and beverage divisions of the Greek hotel industry, as these were perceived by the Greek purchasing managers themselves; (2) investigate the underlying factors when changing a supplier.

A survey was conducted using a closed-ended type questionnaire. Data collection met the following three criteria: hotels with a fully operational food and beverage division could participate in the research, the research population comprised all the hotels located in 13 regions of Greece, the sample represented over 10% of the total hotels in each region. Finally, 653 valid questionnaires were collected.

Exploratory factor analysis showed that six broad sets of factors affect supplier selection in the food and beverage divisions: those related to raw materials, financing, environment, services, origin-nutrients and people. Regarding the factors considered in changing a supplier, three factors were found: service and product quality, economic policy change, food quality and safety management systems.

Greek hotel managers could use the findings of the study to effectively create a supply chain management strategy that will lead to improved firm performance. Understanding the importance of the selection criteria for the supply chain performance and the need to build strong relationships with stakeholders, suppliers could also create a proper supply chain.

The study adds to the knowledge regarding the perspectives of the Greek purchasing managers in food and beverage divisions in hotel industry and the body of much-needed research. Using exploratory factor analysis, a sort of grouping of the variables seems beneficial for simplifying how to present and understand the factors affecting supplier selection in food and beverage divisions within the Greek context.
