Since the popularisation of the internet, low-income Brazilians have received little government support to help them access it. In response, they have largely self-financed their digital migration. Internet cafés became prosperous businesses in working-class neighbourhoods and rural settlements, and, more recently, families have aspired to buy their own home computer with hire purchase agreements. As low-income Brazilians began to access popular social media sites in the mid-2000s, affluent Brazilians ridiculed their limited technological skills, different tastes and poor schooling, but this did not deter them from expanding their online presence. Young people created profiles for barely literate older relatives and taught them to navigate platforms such as Facebook and WhatsApp. Based on 15 months of ethnographic research, this book aims to understand why low-income Brazilians have invested so much of their time and money in learning about social media. Juliano Spyer explores this question from a number of perspectives, including education, relationships, work and politics. He argues that social media is the way for low-income Brazilians to stay connected to the family and friends they see in person on a regular basis, which suggests that social media serves a crucial function in strengthening traditional social relations.

Collective Action 2.0 explores the issues related to information and communication technologies (ICTs) in detail, providing a balanced insight into how ICTs leverage and interact with collective action, which will have an impact on the current discourse. Recent events in different authoritarian regimes, such as Iran and Egypt, have drawn global attention to a developing phenomenon in collective action: People tend to organize through different social media platforms for political protest and resistance. This phenomenon describes a change in social structure and behavior tied to ICT. Social media platforms have been used to leverage collective action, which has in some cases arguably lead, to political revolution. The phenomenon also indicates that the way information is organized affects the organization of social structures with which it interoperates. The phenomenon also has another side, which is the use of social media for activist suppression, state and corporate surveillance, commodifi cation of social processes, demobilization, or for the mobilization of collective action toward undesirable ends. Analyzes social media and collective action in an in-depth and balanced manner Presents an account of avoiding technological determinism, utopianism, and fundamentalism Considers the underlying theory behind quick-paced social media Takes an interdisciplinary approach that will resonate with all those interested in social media and collective action, regardless of fi eld specialism

Is it possible to disseminate science through social networks? Facebook was created to share thoughts, ideas, sensations and anything mild and fleeting; certainly not for the dissemination of scientific and academic knowledge. On the contrary... by combining the obligatory conciseness of a post, the taste for fantasy at the service of the dissemination of scientific knowledge, and the socialization of such a widespread means of communication, there is a metamorphosis turning the irreversible, ineffable volatility of a social network into the lapidary and realistic fixity of this book of digital cameos, dedicated to many aspects of chemistry, a science which is so inextricably enveloped in our daily life. A “chemical” Rector disguises himself as Alice and ventures into a land, the Facebook land, where the wonders coming from imaginative journeys in matter, in its laws and in its imponderable enigmatic nature, take shape.

In terms of media and communication history, we are arguably in the midst of a social media paradigm. Well-known platforms like Twitter and Facebook have gone from being viewed as mere sites of teenage distraction to becoming embedded ICT infrastructure in mainstream organisations across the society, culture, and economy; such platforms, their uses, and their politics are increasingly entangled with everyday life, work, and relationships. For the past decade there has been a burgeoning interest in social media. This highly international Handbook addresses the most significant research themes, methodological approaches and debates in this field via substantial chapters specially commissioned from leading scholars coming from a range of disciplinary perspectives centered on but extending beyond the social sciences and humanities.
