Efficacy of LAIV-T on absentee rates in a school-based health center sample.

Purpose: To determine the effectiveness of the intranasal LAIV-T in decreasing school absenteeism in a school-based vaccination initiative and to compare the acceptability of LAIV-T versus TIV among adolescents.

Methods: This study was conducted within a single, urban community high school in the Fall of 2006. Participation was offered to all students in grades 6 to 10, aged 11 to 17 years.

Models of errors of omission in aphasic naming.

Five computational models of lexical access during production are tested for their ability to account for the distribution of aphasic picture-naming errors. The naming profiles (N= 14) were chosen from the literature to represent patients who make a relatively large number of omission errors. The most successful models combined the damage assumptions of the semantic-phonological model of lexical access (Foygel & Dell, 2000) with a treatment of omission errors as largely independent from overt errors (Ruml, Caramazza, Shelton, &Chialant, 2000).
