This profile discusses the organization, goals and practices of the Spanish 15M movement. I argue that it developed as a complex, multi-layered ecosystem, mobilizing a new generation of citizens through the convergence of struggles over housing and the Free Culture and Digital Commons Movement (FCM), creating a common framework for action through social networks. Primarily in and through the actions in public squares, the 15M movement also constructed further layers of mobilization, incorporating the networks and skills of previous social movements (such as those mobilizing over inter alia education, health, alternative consumption) and connecting with previous generations who had mobilized over civil liberties in transition to democracy. Furthermore, I argue that links with the Free Culture Movement had a profound effect on the genealogy of 15M—in terms of its composition, agenda, framing and organizational logic. The methodology is based on case studies of both the FCM and 15M between December 2010 and December 2011 in Spain.

Despite the undisputed role of emotions in teamwork, not much is known about the make-up of emotions in online collaboration. Publicly available repositories of collaboration data, such as Wikipedia editor discussions, now enable the large-scale study of affect and dialogue in peer production. We investigate the established Wikipedia community and focus on how emotion and dialogue differ depending on the status, gender, and the communication network of the editors who have written at least 100 comments on the English Wikipedia's article talk pages. Emotions are quantified using a word-based approach comparing the results of two predefined lexicon-based methods: LIWC and SentiStrength. We find that administrators maintain a rather neutral, impersonal tone, while regular editors are more emotional and relationship-oriented, that is, they use language to form and maintain connections to other editors. A persistent gender difference is that female contributors communicate in a manner that promotes social affiliation and emotional connection more than male editors, irrespective of their status in the community. Female regular editors are the most relationship-oriented, whereas male administrators are the least relationship-focused. Finally, emotional and linguistic homophily is prevalent: editors tend to interact with other editors having similar emotional styles (e.g., editors expressing more anger connect more with one another). Emotional expression and linguistic style in online collaboration differ substantially depending on the contributors' gender and status, and on the communication network. This should be taken into account when analyzing collaborative success, and may prove insightful to communities facing gender gap and stagnation in contributor acquisition and participation levels.

The platform economy is growing exponentially while creating expectations for its potential to contribute to a sustainable development. However, research aimed at showing the potential contribution of each platform’s business model to sustainable development is needed. The Sustainable Development Goals (SDGs) are driving the policy agenda, but it remains unclear how far they encourage a sustainable platform economy. First, this article aims to study how each different type of platform contributes to sustainable development. Second, it analyses if and how the factors that contribute to the sustainable design of platforms are considered in SDGs. The paper departs from a framework of sustainable democratic qualities of the platform economy that considers governance, economic sustainability, technological and data policies, social responsibility, and external impact dimensions. The study is based on an empirical analysis of 60 platforms. The results show that a sustainable design of a platform economy promotes sustainable development. Furthermore, the contributions of the sustainable dimensions of a platform to SDGs are mainly connected to the impact and responsibility and the economic model, but governance and data dimensions are not present in the SDGs. This suggests that SDGs should improve their digital perspective to intertwine better with the sustainable platforms.

The term “collaborative economy” or “collaborative economy platforms” refers to exchange, sharing, and collaboration in the consumption and production of capital and labor among distributed groups, supported by a digital platform. Collaborative economies’ use is growing rapidly and exponentially, creating high expectations of sustainability and their potential to contribute to the democratization of the economy. However, collaborative economy platforms lack a holistic framework to assess their sustainability and pro-democratization qualities. In addition, there is confusion about platforms which present themselves as collaborative when they actually are not, and similar uncertainties and ambiguities are associated with diverse models. To address this confusion, this article provides a framework for assessing the pro-democratic qualities of collaborative economy initiatives. It was applied to 10 cases in the context of the city of Barcelona. The methods used in this study include mapping and typifying 10 collaborative economy cases in the city, structured and in-depth interviews, and a co-creation session. The results indicate the presence of several modalities for favoring democratic values in a collaborative economy.

The impressive success of peer production – a large-scale collaborative model of production primarily based on voluntary contributions – is difficult to explain

This article presents a framework for evaluating the sustainability qualities of Platform Economy initiatives. It takes into account governance, economic model, technology, data policies, social responsibility and impact. The framework has been tested empirically in a sample of one hundred commons-based peer-to-peer production cases identified in Barcelona. Data collection was based on online ethnography and structured interviews. The results reveal the different levels and tendencies of pro-democratization. It appears that the cases that are more sustainable are also sustainable in other dimensions. The analysis found a correlation between governance and technology and data models, and it further demonstrated that governance is correlated with the economic model. Both results together indicate that the governance of a platform plays a central role in its overall approach.
