The methodological tool chest available to those who study digital technologies ranges from those that are uniquely digital methods to approaches that are well established in the social sciences. This domain of work includes the application of methods to answer questions about the relationship between digital technologies and the social world, as well as the use of digital methods to answer questions about the offline world. New or old, quantitative or qualitative, the methods used to study the digital have strengths and weaknesses unique to this area of research. These issues include questions about the scope of cyberethnography, the validity of trace data, and the analytical division between on- and offline interaction. This review focuses on an overview of different methods, their history, and their strengths and weaknesses as applied to the study of digital technologies, including ethnographic approaches, interviews, surveys, time and media diaries, trace data, and online experiments.

The structure of people's social networks predicts democratic engagement. However, the relative contribution of different types of social ties to civic and civil behaviors is unclear. This paper explores the role of core networks - bonding social capital - to the role of overall network diversity - bridging social capital - for participation in formal civic institutions and informal civil behaviors. Emphasis is placed on the possible role of heterogeneity within core networks - political disagreement and the presence of nonkin ties - and on frequency of interaction, in-person and mediated: mobile phone and the Internet. This study finds that overall network diversity is a more consistent and substantive predictor of civic and civil behaviors than the size or heterogeneity of the small number of ties that make up the core network of most people. The two dominant new media used to interact with core network members - email and mobile phones - are unrelated to any of the behaviors measured. Some other media - contact in-person, postal mail, texting, instant messaging, and social network services - have an inconsistent and modest relationship to civic and civil behaviors. Findings lead to speculation that political disagreement within core networks, typically associated with lower levels of political participation, has a spillover effect that results in other forms of democratic engagement. There is evidence of glocalization; contact with core ties using new media supports local civil and civic behaviors. Internet use largely supports democratic engagement through interaction with bridging, but not bonding ties. [ABSTRACT FROM AUTHOR]

This study examines the relationship between mode of Internet access, variety of online activities, and the potential for the Internet to contribute to local social capital in distressed, urban communities. Based on a sample of 525 telephone surveys in Detroit, findings show that breadth of access predicts participation in a larger variety of online activities, which is associated with higher levels of local social capital. Neither public Internet access, home broadband, nor Internet access through a mobile phone data plan alone affords participation in a full range of social capital-enhancing activities. The findings highlight the potential problems of initiatives that assume equivalent social outcomes through nonequivalent modes of access, such as providing Internet access through mobile phones in place of home broadband. Efforts to enhance a city's social infrastructure by providing Internet access are best served when individuals have multiple points of access available. [ABSTRACT FROM AUTHOR]
