The study seeks to add to the current debate on English as a lingua franca by analyzing the role of the native speakers of English in intercultural business negotiations and to what extent they effectively accommodate lingua franca speakers. The data, gathered from a sample of 14 native English speakers and 13 nonnative English speakers, consist of interactions collected through a discourse completion task and a short questionnaire. The results showed that the native speakers in this sample used a wider range of linguistic devices than the nonnative speakers. The majority of the native speakers attempted to accommodate nonnative speakers, but there was significant variation in the way that individual participants chose their strategies and approached accommodation. The most striking finding was the imbalance between the native speakers' understanding of the issues of intercultural communication and their inability to effectively accommodate nonnative speakers. The implications are discussed.

A series of 36 compounds of known structure was used in a study to elucidate the mechanism of separation of gel‐permeation chromatography (GPC). The various molecular dimensions were defined and measured for these compounds. The elution volume for these compounds was determined by GPC under specified and controlled conditions. The relationships between elution volume and molecular dimension were investigated using computer‐based statistical analysis for the entire set of compounds and manual simultaneous equations for smaller sets of compounds. It was found that, as increasingly more molecular dimensions are considered, (1) the importance of the maximum molecular dimension Ap′ (the only dimension considered by many investigators) significantly decreases and (2) a significantly better prediction of the elution volume of these compounds could be made.
