This study examined the effects of time restriction on social interaction in computer-mediated communication through a meta-analysis of applicable research. Time was defined as whether subjects were restricted or unrestricted in their opportunity to exchange messages. Studies were included that assessed either of two outcome variables: socially oriented (as opposed to task-oriented) communication, and negative / uninhibited communication. Hypotheses were derived from Walther's social information processing perspective. Meta-analytic tests supported the hypotheses on social communication. Although no effects were found on negative / uninhibited communication, a reexamination of original studies suggests caution regarding previous findings.

This article addresses whether dead public intellectuals differ from living public intellectuals in terms of their social network properties in the mass and internet media. Explicated at the theoretical level is the macro-level asynchrony of the web, moving beyond micro-level conceptualizations. Networks for 662 actors which Posner defined as public intellectuals are analyzed based on data from Nexis for magazines, newspapers and broadcast media, and on the web through Google and Google Groups. The differences between the media profiles of dead and living public intellectuals are assessed. As hypothesized, there are no significant differences between living and dead public intellectuals in hits for webpages and for Google Groups threadedness. Also, mass media hits show a significantly higher frequency for the living. Findings show that dead public intellectuals have a social `afterlife', a sociomorphic quality that continues in cyberspace and not in other media.

This paper assesses the potential benefits of composite forecasting methods as applied to commodity prices. Conditions under which composite forecasts are most applicable are examined. A Monte Carlo simulation and empirical examples are used to assess the benefits of composite forecasts and provide guidelines on the selection of appropriate methods. The importance of independent pieces of information and why composites cannot be a cure for poor forecasts under many realistic situations are discussed.

Marginality is an important concept in the history of science, though it is often used in a manner that presumes marginality to be a static designation. We contend that the dynamics of marginality are crucial to the history of psychoanalysis, a discipline that has moved between dominant and marginal positions. We address psychoanalytic marginality via three specific "cases": the marginalization among Freud and his followers when psychoanalysis was an emergent discipline; the marginality trope in Erich Fromm's popular psychoanalytic writing when psychoanalysis was orthodoxy in American academic psychiatry; and the rhetorical marginality of psychoanalysis in Sweden as psychoanalysis entered a decline within psychiatry. Our aim is to show that marginalization and self-marginalization serve interpersonal, social, and professional strategies.
