The Syntopia Project and internet sociology Beginning in 1995, Katz and Philip Aspden initiated the Syntopia Project, an early program using national random telephone surveys to examine the social effects of Internet use in the
United States. Ronald E. Rice joined in 2000. Surveys conducted in 1995, 1996, 1997, and 2000 compared users and non-users on civic involvement and social interaction. The findings did not support claims that Internet use led to social isolation. Katz described the Internet as supplementing, rather than replacing, social capital. The project also identified “Internet dropouts,” referring to individuals who discontinued use after initial adoption.
Mobile communication and occupational bifurcation Katz conducted early empirical research on mobile communication in the United States, including a 1995 national survey of beeper and mobile phone users while at Bellcore. The study examined everyday use of mobile devices and introduced the concept of occupational bifurcation, in which higher-status professionals experienced increased mobility, while lower-status workers experienced greater managerial oversight.
Obscene and harassing telephone calls In a 1994 article, Katz reported findings from a nationally representative survey of obscene and harassing telephone calls. The study distinguished between random and targeted callers and found that women were the primary targets, though some men also reported such calls. == Theoretical frameworks ==
