The aim of this study was to replicate and extend results of a previous trial that investigated the effectiveness of 2 peer-led eating disorders prevention interventions in reducing eating disorder risk factors in undergraduate women (C. B. Becker, L. M. Smith, & A. C. Ciao, 2006). To extend findings from the previous study by allowing for investigation of differential response, the authors ran...

From a developmental perspective, a central goal ofprevention is to alter behaviors that are already changing-that is, to redirect potentially risky trajectories. This multiwave panel study examines the longer-tem e f i t s of a prevention program on trajectories of alcohol misuse and related risk factors (susceptibility to peer pressure to misbehave and exposure to peer alcohol use). We concep...

content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....

In this study, the researcher used the many-facet Rasch measurement model (MFRM) to detect two pervasive rater errors among peer-assessors rating EFL essays. The researcher also compared the ratings of peer-assessors to those of teacher assessors to gain a clearer understanding of the ratings of peer-assessors.
