Nowadays, Circular Economy (CE) is one of the most popular notions among politicians, practitioners and academics. While several researchers indicate that the concept of the Circular Economy synthesises the major schools of thought regarding sustainability, no explicit analysis is available on the roots, theoretical backgrounds, and the novelty of CE or its understanding on the role of technology and innovation in achieving the goals of sustainable development. Based on a structured literature review, the goal of this paper is twofold: fi rst, it aims to identify the main conceptual similarities and diff erences between the earlier technology-oriented concepts of sustainability and the Circular Economy, and secondly, it attempts to present how technological innovation is conceptualised in the Circular Economy. The main fi ndings suggest that CE relies heavily on the previous theories of technology-oriented research streams, especially Blue Economy, emphasising the importance of innovation cascades and system innovation.

Keywords: sustainable development, innovation, circular economy, eco-effi ciency, blue economy, natural capitalism, industrial ecology, bio- and eco-mimicry.

As family-friendly hotels become more and more popular, and a growing number of hotels claim to be family-friendly, it still remains unclear how the concept of familyfriendliness can be best defi ned. The main aim of our research was to examine how professionals perceived the notion of family-friendliness in their everyday practice. To that end, a series of in-depth expert interviews was conducted. Our results show that family-friendliness still remains a fuzzy concept for both service providers and consumers. Our research established a “continuum of family-friendliness” along the two main dimensions of physical environment and holiday experience where dissatisfi ers and delighters of a family-friendly accommodation are identifi ed. Our results contribute to further positioning strategies for hotels that aim to use the “family-friendly” label in their service off ering.

The goal of this paper is to draw decision-makers’ attention to the importance of regulatory focus theory (RFT) with a view to supporting their daily decision process. RFT divides people into two types based on the decision-making style they embrace in the face of risk: promotion-oriented (driven by prospective success) and prevention-oriented (propelled by the desire to avoid losses). Work teams have their own regulatory foci, which can be very diff erent from team members’ individual orientations and profoundly determine the group’s attitude to risk. Regulatory focus has an impact on regulatory fi t, risk attitude, sunk cost bias, framing, collective decisions, moral engagement and belonging, creativity as well as health and emotions. Decision-makers have to know their people’s regulatory foci as well as their own in order to improve decision quality. They should know how they can temporarily replace chronic regulatory focus with an induced one in order to infl uence attitudes to risk (e.g. through time pressure, framing or mindful selection of team members).

Keywords: regulatory focus, regulatory fi t, decision-making, ethics.

The main aim of this paper is to reduce the indicators of the European Union’s Sustainable Development Strategy and the United Nation’s 2030 Agenda indicators through Principal Component Analysis, with minimal information loss. The European Union’s Sustainable Development Indicator System (EU SDIs) was grouped around 130 indicators based on 10 topics. Over time, this indicator system has been reworked due to the overriding goals, objectives and the progress made. In 2015, in Paris, 193 UN member states signed the next global sustainability programme. The 2030 Agenda framework strategy uses indicators that are diffi cult to interpret because of their size and their progress. Within the strategy, 244 indicators have been created, covering the three aspects of sustainable development. The current study describes a method to reduce the sustainable development indicators that are part of the strategy. With this reduction, progress on sustainable development goals can be more easily understood at the European Union level. The principal component determines the properties, characteristics and indicators that have the greatest impact on sustainability. With this method, I can reduce the size of the database and, at the same time, drawing conclusions becomes easier and faster.

Keywords: sustainable development indicator system, EU Sustainable Development Strategy, UN 2030 Agenda, Principal Component Analysis.
