Text complexity can be reduced by making different choices at the lexical and grammatical levels. However, discourse-level choices may also affect a text’s complexity. In a coherent text, explicit discourse relations (e.g. CAUSE, CONDITION) are expressed using discourse markers (e.g. since, because, etc.) that may be preferred for texts at different readability levels. In this paper, we investi...

At present, discourse parsing is an important research topic. Rhetorical Structure Theory (RST) is one of the most popular approaches in this field.

To evaluate multidrug-resistant strains of Salmonella enterica serotype Typhimurium, including definitive type 104 (DT104) in the United States, we reviewed data from the National Antimicrobial Resistance Monitoring System (NARMS). In 1997 to 1998, 703 (25%) of 2,767 serotyped Salmonella isolates received at NARMS were S. Typhimurium; antimicrobial susceptibility testing and phage typing were c...

BACKGROUND One of the most difficult aspects of conducting clinical research is the ability to successfully recruit participants. Pediatric clinical research presents unique recruitment challenges that relate to the need for parental consent on behalf of a minor, child assent, and school attendance. Yet, this has been less well studied. We conducted a survey of investigators performing human su...
