The prolific growth of cable television and videocassette recorders, in particular, has been propelled by the availability of uncut R-rated adult programming (4). Such programming is generally off-limits to children when it appears in print and in movie theaters, but despite the efforts of many state regulators, it is widely available over cable (see, e.g., Jones u. WiIkinson (1987), cert. denied, 107 S. Ct. 1559). Thus, parents represent the sole "regulators" of what has been called "developmental eavesdropping" (32)-children watching media content that is considered more appropriate for older viewers. If parents do regulate their child's viewing, their mediation usually takes the form of rules, prohibitions, or discussions.Past research on parental mediation of children's television viewing has focused primarily on homes that receive only broadcast television. To build a more comprehensive model of contemporary television viewing habits in the new video environment, this article analyzes the role that might be played by cable television and VCRs along with other factors known to have an impact upon parental mediation of children's television viewing.Given the large number of potential influences on parental mediation, we wanted to measure their impact and possible interaction within a larger behavioral model. As Kurdek's (25) review of home ecology literature suggests, parent and child interaction such as mediation is readily amenable to Bronfenbrenner's typology of ecological niches (11, p. 226).

A content analysis of 48 citizen journalism sites, 86 weekly newspapers and 138 daily newspapers indicates that citizen journalism sites differed enough in six local government content attributes to conclude that citizen journalism sites are, at best, imperfect information substitutes for most newspapers. However, the data also indicate that some large-city citizen journalism sites complement newspapers by increasing the number of news stories and the amount of opinion available about local government. The results also found differences between citizen news sites and citizen blog sites. Few citizen journalism sites outside of large metropolitan cities covered local government.
