The approach to analysing population ageing and its impacts on the economy has evolved in recent years. There is increasing interest in the development and use of products and services related to gerontechnology as well as other social innovations that may be considered as central parts of the ''silver economy.'' However, the concept of silver economy is still being formed and requires detailed research. This article proposes a typology of models of the silver economy in the European Union (EU) at the national and regional levels. This typology was created by comparing the Active Ageing Index to the typology of varieties and cultures of capitalism and typology of the welfare states. Practical recommendations for institutions of the EU and directions for further research are discussed.

His research focuses on gerontology, labor economics, public management, and social policy. He has more than 80 publications including 35 chapters in books and 3 chapters in 2 encyclopaedias (Encyclopaedia of Human Services and Diversity and The Encyclopaedia of Diversity and Social Justice). He has published academic articles in both Polish and English in sociology and economics journals, and his most recent publications include Social Capital of Old People on the Example of Bialystok Residents (in Polish) and Experts and Cultural Narcissism.

Putting Theory into Practice▶ Presents the benefits of creativity in older populations ▶ Underlines strategies for implementing intergenerational public policy ▶ Forewords and afterwords by prominent researchers expand the discussion This book shows that global population ageing is an opportunity to improve the quality of human life rather than a threat to economic competitiveness and stability. It describes the concept of the creative ageing policy as a mix of the silver economy, the creative economy, and the social and solidarity economy for older people. The second volume of Economic Foundations for Creative Ageing Policy focuses on the public policy and management concepts related to the use of the opportunities that are created by population ageing. Klimczuk covers theoretical analyses and case study descriptions of good practices to suggest strategies that could be internationally popularized. Each chapter includes exercises and assignments for both students and those who are likely to apply the presented concepts in practice.

The chapter is the final one in the volume of collected papers aiming to discuss the sharing economy in Europe. The idea of the book emerged within the research network created by the COST Action CA16121 ‘From Sharing to Caring: Examining Socio-Technical Aspects of the Collaborative Economy.’ The authors of the chapter sum up theoretical and empirical materials as well as country-specific cases provided in the book. The article critically assesses the current status of the sharing economy in European countries by highlighting major controversial issues related to deregulation, market disruption, or social inequality. The authors conclude that, considering the comprehensive and up-to-date materials collected and analysed in the book, it may become an outstanding source of knowledge and a practical tool in the process of expansion of the sharing economy in Europe and beyond.

Nowadays is growing importance of interdisciplinary research and in the eld of cultural diversity, multiculturalism and intercultural cooperation. It is important also to take into account the global processes of changes associated with the dissemination of digital information and communication technologies. One of the theories which are essential in this area of research is the concept by E. Sapir and B.L. Whorf. The purpose of the article is to introduce into a current condition of scienti c dispute concerning the views of these authors on the relationship between language and cognition. Paper is based on a critical analysis of the literature.

W tym miejscu uznaje się, iż spór naukowy dotyczący poglądów tych autorów na relacje pomiędzy językiem a poznaniem pozostaje aktualny w kontekście współczesnego wzrostu znaczenia badań interdyscyplinarnych oraz badań z zakresu zróżnicowania kulturowego, wielokulturowości i współpracy międzykulturowej. Jednocześnie obserwujemy globalne przemiany związane z upowszechnianiem cyfrowych technologii informatycznych i telekomunikacyjnych. Koncepcja Sapira i Whorfa wydaje się inspirująca w przypadku badań nad współcześnie podzielonym, sfragmentaryzowanym dyskursem publicznym, w którym coraz więcej przekazów i dyskusji odbywa się nie tylko poprzez
