A variety of innovative pilot projects are being implemented to improve the life-course resilience of existing and newly built home environments. We refer to these projects as “socio-technical experiments” that embody different kinds of promising futures and provide direction to current developments in the emerging domain of age-friendly homes. To take stock of this diversity within Europe, this paper provides an overview of 53 ongoing socio-technical experiments that are being conducted in the Netherlands, France, Ireland and Poland. We find that, besides the variation between European countries, there is a more important type variation in terms of the character of the experiments themselves and the differences in development direction that they propose. Our findings suggest that most of the innovations tested in these experiments are not primarily material or technical but primarily social or conceptual in character (i.e., new organizational modes or everyday practices that re-arrange social relations or new housing concepts that bridge the divide between ageing in place individually and a nursing home). This variety of innovations tested in the experiments can be categorized into seven distinct innovation pathways: (1) Showcasing Technology, (2) Innovation Ecosystem, (3) Sheltered Elite, (4) Specific Community, (5) Conscious Retrofitting, (6) Home Sharing and (7) Retrovation Challenge.

Despite its growing ubiquitous presence, the smart city continues to struggle for definitional clarity and practical import. In response, this study interrogates the smart city as global discourse network by examining a collection of key texts associated with cities worldwide. Using a list of 5,553 cities, a systematic webometric exercise was conducted to measure hit counts produced by searching for ‘smart city’. Consequently, 27 cities with the highest validated hit counts were selected. Next, 346 online texts were collected from among the top 20 hits across each of the selected cities, and comprehensively analysed both quantitatively and qualitatively using AntConc software. The findings confirm, on one hand, the presence of a strong globalising narrative which emphasises world cities as ‘best practice’ models. On the other, they reveal the smart city’s association – beyond the quest for incremental, technical improvements of current urban systems and processes – with a pronounced transformative governance agenda. The article identifies five critical junctures (interlocking discourses) at the heart of the evolving smart city discourse regime; these shed light on the ongoing boundary work in which the smart city is engaged and which contain significant unresolved tensions. The paper concludes with a discussion of resulting implications for research, policy and practice.

Despite a surge of multidisciplinary interest in transition studies on low-carbon mobilities, there has been little evaluation of the current state of the field, and the contributions of different approaches such as the multi-level perspective (MLP), theories of practice, or the new mobilities paradigm. As a step in this direction, this contribution brings together scholars representing different theoretical perspectives and disciplinary fields in order to discuss processes and uneven geographies of mobility transitions as they are currently theorized. First, we reflect upon the role of geographers and other social scientists in envisioning, enabling, and criticizing mobility transitions. Second, we discuss how different theoretical approaches can develop mobility transitions scholarship. Finally, we highlight emerging issues in mobility transitions research.

Vast numbers of people in rapidly growing cities throughout the developing world depend on informal transport services for their mobility needs. Thus far the field of transition studies has addressed the dynamics of socio-technical change in situations where regimes of automobility and sanctioned public transport constitute the dominant order, but not in contexts of cities in the developing world, where informal transit thrives. In this paper we enquire about stability and prospects for change in these kinds of socio-technical systems. To this end, we trace the evolution of Bangkok's motorcycle taxi industry including recent efforts to introduce a potentially radical innovation: an information and communications technology (ICT) platform used as a taximeter. The paper concludes that innovations in informal urban transport are opening up alternative mobility pathways for the developing world, which might even spread far beyond their original confines into the West; and that the persistence of informal transport systems and the proliferation of innovations within those systems in developing countries prove to be relevant phenomena for defining prominent topics on the agenda of (sustainability) transitions research.
