This multi-faceted collection of research papers focuses on advisory practices in different contexts. Data is drawn from academic, educational and training settings, health-related practices, and computer-mediated communication. The languages involved are Cantonese, English, Finnish, Japanese, Spanish and Russian. The papers treat professional and institutional practices, practices that contain peer interaction within an institutional framework, and non-institutional peer interaction, as well as solicited and non-solicited advice in written and spoken form. The work reported on clearly demonstrates the complexity of the advisory activity, which needs to be studied in its cultural framework and interactional context. The richness and diversity of this practice is studied from different methodological angles, covering qualitative and quantitative as well as theoretical and empirical analyses.
