This final substantive report includes the working papers presented by the American and Japanese participants, notes on discussions, a summary of an address by William Labov, and draft proposals for joint sociolinguistic research. The working papers involve several sociolinguistic issues in Japanese-American and Japanese culture. The American papers concern lexical borrowing by Japanese Americans in Hawaii, phonological reduction rules for evaluation in sociolinguistic analysis, sociolinguistic factors inhibiting Japanese-American communication, language and social change, and mutual understanding between Japanese and Americans. The Japanese papers treat cultural comparisons, language behavior and cultural patterns, the ethnography of self-reference and address in Japanese, approaches to studying contrasting cultures, and the use of Japanese invective words or curses. References and notes are included with the papers along with a summary of the discussions that followed the presentation of each paper. (VM)
