Importante nuovo studio Pew sull'impatto delle tecnologie sull'isolamento sociale. Chiacchiere-italiche-sull'argomento: R.I.P. juan carlos http://www.pewinternet.org/Reports/2009/18--Social-Isolation-and-New-Technol... * Social Isolation and New Technology* by Keith Hampton, Lauren Sessions, Eun Ja Her, Lee Rainie Nov 4, 2009 *Overview* This report adds new insights to an ongoing debate about the extent of social isolation in America. A widely-reported 2006 study argued that since 1985 Americans have become more socially isolated, the size of their discussion networks has declined, and the diversity of those people with whom they discuss important matters has decreased. In particular, the study found that Americans have fewer close ties to those from their neighborhoods and from voluntary associations. Sociologists Miller McPherson, Lynn Smith-Lovin and Matthew Brashears suggest that new technologies, such as the internet and mobile phone, may play a role in advancing this trend. Specifically, they argue that the type of social ties supported by these technologies are relatively weak and geographically dispersed, not the strong, often locally-based ties that tend to be a part of peoples' core discussion network. They depicted the rise of internet and mobile phones as one of the major trends that pulls people away from traditional social settings, neighborhoods, voluntary associations, and public spaces that have been associated with large and diverse core networks. The survey results reported here were undertaken to explore issues that have not been probed directly in that study and other related research on social isolation: the role of the internet and mobile phone in people's core social networks. *This Pew Internet Personal Networks and Community survey finds that Americans are not as isolated as has been previously reported. People's use of the mobile phone and the internet is associated with larger and more diverse discussion networks. And, when we examine people's full personal network -- their strong and weak ties -- internet use in general and use of social networking services such as Facebook in particular are associated with more diverse social networks.* *About the Survey *The Personal Networks and Community Survey, sponsored by the Pew Internet & American Life Project, obtained telephone interviews with a nationally representative sample of 2,512 adults living in households in the continental United States. The survey was conducted by Princeton Survey Research International. The interviews were conducted in English by Princeton Data Source, LLC between July 9, 2008 and August 10, 2008. Statistical results were weighted to correct known demographic discrepancies. The margin of sampling error for the complete set of weighted data is ±2.1%. Regression tables are available here.
