We studied the community structure pattern in the visualizations of ten personal social networks on Facebook at a single point in time. It seems to be a strong tendency towards community formation in online personal, social networks: somebody’s friends are usually also friends between them, forming subgroups of more densely connected nodes. Research on community structure in social networks usually focuses on the networks’ statistical properties. There is a need for qualitative studies bridging the gap between network topologies and their sociological implications. To this direction, visual representations of personal networks in social media could be a valuable source of empirical data for qualitative interpretation. Most of the personal social networks’ visualizations in the present study are very highly clustered with densely-knit overlapping subgroups of friends and interconnected between them through wide bridges. This network topology pattern seems to be quite efficient, allowing for a fast spread and diffusion of information across the whole social network.

This paper provides a comprehensive and systematic review of literature pertaining to consumer/household/residential adoption and diffusion issues in relation to ICT/IT/IS to ascertain the current “state of play” within the field along a number of dimensions. Eighty articles on the adoption, acceptance and diffusion of ICT/IT/IS, published in 54 peer reviewed journals between 1998 and 2008, were reviewed, from which information on a series of variables were extracted. The subsequent findings suggest that the positivist paradigm, empirical and quantitative research, the survey method and the TAM theory were predominantly used when investigating the topics of the adoption and diffusion of technology within the consumer/household/residential context.

Urban development in the areas surrounding active volcanoes has led to increasing risks in southern Peru. In order to evaluate the hazard, the Instituto Geológico, Minero y Metalúrgico (INGEMMET) created a Volcano Observatory (OVI) to carry out detailed geological investigations to understand eruption histories and provide volcanic hazard maps. The generation of geological information on volcanoes has allowed the identification of scenarios and zoning of potentially impacted areas. This information has also allowed OVI to implement surveillance networks giving priority to the volcanoes that pose the greatest risk to the population, infrastructure, and economic activities. Since 2006, OVI has been running volcanic monitoring networks with a multidisciplinary approach, improving real-time transmission, and making timely forecasts. Based on geological information and the risk posed by the volcanoes, the greatest efforts have been made to monitor Sabancaya, Misti, Ubinas, and Ticsani volcanoes. Following the order of priorities, monitoring of Coropuna, Huaynaputina, Tutupaca and, Yucamane volcanoes has also been developed. In addition, OVI carries out routine education activities and diffusion of information that serve to manage volcanic risk in Peru. El desarrollo urbano en zonas aledañas a volcanes activos ha conllevado a la generación de riesgos cada vez mayores en el sur del Perú. Con la finalidad de evaluar el peligro, el Instituto Geológico, Minero y Metalúrgico (INGEMMET) creó un observatorio vulcanológico (OVI) para realizar estudios geológicos detallados que permitan conocer las historias eruptivas y elaborar mapas de peligros volcánicos. La generación de información geológica sobre los volcanes ha permitido la identificación de escenarios y la zonificación de áreas con potencial a ser afectadas. Esta información también ha permitido al OVI implementar sus redes de monitoreo priorizando los volcanes que representan mayor riesgo para la población, la infraestructura y las actividades económicas. Desde el año 2006, el OVI viene implementando redes de vigilancia volcánica con un enfoque multidisciplinario, mejorando la transmisión en tiempo real y realizando pronósticos oportunos. En base a la información geológica y el nivel de riesgo de los volcanes, se han puesto los mayores esfuerzos en monitorear los volcanes Sabancaya, Misti, Ubinas y Ticsani. Siguiendo el orden de prioridades, el OVI ha comenzado, también, el monitoreo de los volcanes Coropuna, Huaynaputina, Tutupaca y Yucamane. Además, el observatorio desarrolla actividades permanentes de educación y difusión de la información que sirven a la gestión del riesgo volcánico en el Perú.

This chapter examines how the multiplication of digital metrics, analytics, and algorithms is reconfiguring work practices and professional identities. It focuses on the case of journalism, a field that has been profoundly changed by digital technologies. It describes modern newsrooms that use digital tools in the gathering, production, and diffusion of information on the web, from group chats to social media platforms and content management systems. The chapter also introduces a new market that emerged for “web analytics” or software programs that track the behaviour and preferences of internet users. It describes how editors and journalists are provided with a constant stream of data about their audience, receiving increasingly detailed information in real time about the number of visitors, comments, likes, and tweets that their articles attract.
