Abstract. Proper field delineation plays an important role in scientometric studies, although it is a tough task. Based on an emerging and interdisciplinary field nanoscience and nanotechnology– this paper highlights the problem of field delineation. First we review the related literature. Then, three different approaches to delineate a field of knowledge were applied at three different levels of aggregation: subject category, publication level, and journal level.

Abstract. This article criticises the social policy literature for equating universalism to the universal coverage of citizens. The current so-called ‘universal’ social protection systems guarantee social citizen rights, while the revisited truly universalism guarantees social human rights for everyone. Crisp-set qualitative comparative analysis (csQCA) is used to map and track the level of exclusiveness or inclusiveness into social pensions in the existing 30 social pension programmes on 28 Latin American and Caribbean (LAC) countries.

Abstract. The introduction of cash-for-care (CfC) schemes in different European countries over the last years has responded to a plurality of strategies aimed at attending the rising demand and increasing costs of the long-term care needs of an ageing population.

Abstract. The rise of mobilities has paved the way for important changes within cities and the possibility for urban upper-middle classes to exit from their cities and national societies, disinvesting on them, while still taking profits in a process of deterritorialization with important consequences at the collective level. Investigating the extent to which upper-middle classes shaped and are still rooted (or not) in their cities is a challenge, even more when international comparison is involved.
