Electronic gatekeepers: Locking out the marketplace of ideas

The Hutchins Commission was concerned that the small minority of the people controlling the press as an instrument of mass communication could misuse their gatekeeping power. Due to new communication technologies the abundance of media outlets has increased choices available to the public far beyond anything commission members could have envisioned. This, in turn, has led to the development of a second layer of electronic gatekeepers between information originators and the public. The effect these electronic gatekeepers will have on the evolution of the press will be as great as, if not greater than, that of the human gatekeepers who were the commission's focus. This article suggests there will be an increasing equation of the public interest with what the public is interested in, a reduction in people's knowledge of public affairs and a decrease in the exposure of individuals to new ideas or ideas that contradict their existing beliefs. The article concludes by questioning whether government regulation is capable of addressing these concerns.     

Self-esteem in early adolescence: The identification and prediction of contrasting longitudinal trajectories

The present study focused on differences in self-esteem trajectory in early adolescence rather than on average change across all children. Longitudinal data from 128 adolescents were obtained over a 2-year period that encompassed the transition from elementary school to junior high school. Cluster analysis revealed four markedly divergent self-esteem trajectories: consistently high (35%), chronically low (13%), steeply declining (21%), and small increase (31%). Attempts to predict trajectories were only partially successful. Peer social support was the strongest predictor, but its relation to self-esteem appears more circumscribed than had been thought. The discussion considers differences in the experience of early adolescence, as well as implications for the design and evaluation of preventive intervention.Funding for this research was provided via awards to Barton J.
