With the digital availability of social data helping reshape ethnographic research and thus broadening the mainstream understanding of ethnography, this research proposes a set of strategies to overcome current limitations in doing ethnography. Based on a two-year online and offline ethnographic project on social media use in later life, insights are provided into how the practices and meanings of ethnography are being reconstructed and negotiated in response to the explosion of digital social data and through team practices. This paper reviews how collaborative and interdisciplinary ethnographic reflection is sustained and extended by digital tools, creating a live source of data that can be analysed within the framework of ethnography. As a contribution to current debates on the 'Social Life of Methods', it also reviews epistemic issues associated with digital data and team ethnography, such as the role of the ethnographer(s), the field(s) and computational data analysis. The article reaches the conclusion that digital team ethnography is a viable option for undertaking thick and descriptive studies about the use of social media, which in turn favours a collaborative, non-hierarchical and dialogue-driven knowledge production process.

Purpose -Social isolation and loneliness are recognised social, health and wellbeing problems that particularly affect later life. They have been the subject of many recent studies. Studies examining the role of the internet in addressing these problems have multiplied. However, it is still not known whether internetmediated social interaction has any role in mitigating social isolation and or loneliness. To address this gap, the purpose of this paper is to review previous research that investigates the relationship between internet use for communication and social isolation and loneliness. Design/methodology/approach -This paper reviews the empirical literature published since 2000 and expands on previous literature reviews by including a variety of research designs and disciplines. Findings -Despite the recent increase in studies, there is still little evidence to show internet effects on social isolation and loneliness. It is concluded that future research programmes aimed at reducing them by the use of the internet should include more robust methodological and theoretical frameworks, employ longitudinal research designs and provide a more nuanced description of both the social phenomena (social isolation and loneliness) and internet-mediated social interaction. Originality/value -Previous reviews are not restricted to internet-based studies and include several types of interventions aiming at reducing social isolation and/or loneliness. They do not attempt to disentangle the internet effects of social isolation and loneliness.

The authors explore transformations in the surveillance and discipline framework proposed by Foucault (technologies that "allow to see," the panoptic as a completely closed space) by analyzing new Global Positioning System (GPS) care technologies. The authors contrast the antinomadic characteristics of traditional care practices for people with dementia with the new "in-movement" GPS care devices. They outline three main displacements: the definition of a new space that erases the distance between separated social and sanitary spaces; the lifting of the boundary between the home and the neighborhood; and finally, we point out the importance of movement in this process. These devices show the emergency of new micropractices of power and control: a new anatomy of surveillance. Grounded on movement, they transform physical barriers into risk alarms that do not block users' way; instead, they generate information that mobilizes others. The authors refer to the notion of kinevalue to explain how these devices turn living organisms' motility properties into a 371 space and culture vol. 12 no.

Luego discutimos las implicaciones de esto para nuestra comprensión de la identidad y el envejecimiento dentro de la sociedad digital. Finalmente, sugerimos que el término ecologías de aprendizaje capta mucho mejor las prácticas de aprendizaje de los adultos mayores.Palabras clave: aprendizaje; medios de comunicación social; adultos mayores; afectos; relaciones; tecnologías digitales.Abstract: This exploratory paper argues that treating older adults learning as «representational knowledge» acquisition is not adequate if we want to understand how they learn to use digital technologies in general, and social media technologies in particular. Using examples taken from an ethnographic study exploring social media use in later life, the case is made for a range of digital practices and affective relations through which learning happens. The idea of communities of practice is a useful approach, however it also needs to be expanded to account for the practices that happened outside of the social and cultural centers and outside of the groups of interest formed around the interests in digital technologies. It is also useful to answer the question of how and why particular forms of «pedagogical authority» are enacted through particular digital practices, which are highly relational and affective, and how these forms of expertise become identity traits. We further discuss the implications of this for our understandings of identity and ageing within the digital society. Finally, we suggest that the term learning ecologies captures much better the practices of learning of older adults.
