User interfaces to WWW search engines typically present results as ranked lists of documents. Such lists give users little help in understanding document variation: we propose a richer representation of retrieval results in the search interface. Fundamental to us is the notion of document grouping. We use both stylistic genre-based document categorization and statistical content-based clusterin...

Foreign Language Education Policy (FLEP) needs to be understood as part of broader educational policies and as situated within overarching social macro plans. In this paper, based on a conception of policy as distinct from goals and objectives, and with a view of the relevant literature, we will present some theoretical guidelines of setting and/or evaluating foreign language education policies...

We investigate the evolution of mass-selected early-type field galaxies using a sample of 29 gravitational lenses spanning the redshift range 0 . z . 1. Based on the redshiftdependent intercept of the fundamental plane in the rest frame B band, we measure an evolution rate of d log(M/L)B/dz = −0.55 ± 0.04 (all errors are 1σ unless noted) if we directly compare to the local intercept measured fr...
