This distinctive monograph examines the dynamic rhetorical processes by which scientists shape‎,‎ negotiate‎,‎ and position their work within an interdisciplinary community‎.‎ Author Ann M‎.‎ Blakeslee studies the everyday rhetorical practices of a group of condensed matter theoretical physicists‎,‎ and presents here the first substantial qualitative study of the planning and implementation of discursive practices by a group of scientists‎.‎ This volume also represents one of the first studies to use situated cognition and learning theory to study how knowledge of a domain‎'‎s discursive practices is acquired by newcomers‎.‎ Unlike previous studies of scientists‎'‎ rhetorical practices‎,‎ which have focused primarily on the finished or published texts‎,‎ Blakeslee‎'‎s involvement with the physicists as they engaged in the composing processes‎-‎-from jotting down planning notes through publishing a scientific paper‎-‎-suggests an alternative view of audience based on cooperative interaction between authors and their interlocutors‎.‎ From this innovative perspective‎,‎ functional knowledge of audiences comes only by entering into some community of practice‎,‎ in which readers also become self‎-defining interlocutors and even participants in joint projects‎.‎ Blakeslee‎'‎s research follows the physicists‎'‎ work into communal‎,‎ interactive dynamics‎,‎ looking at their overt attempts to get feedback from members of their audiences‎,‎ what that feedback was‎,‎ and how they responded to it‎.‎ This work addresses and extends a model for audience analysis that consists of two primary operations‎:‎ getting to know and understand one‎'‎s interlocutors‎,‎ and determining how to reach and influence them‎.‎ In doing so‎,‎ it offers important insights into the dissemination of scientific information‎,‎ and thus will be of great interest to scholars and students in the areas of rhetoric of science and technology‎,‎ composition‎,‎ rhetorical theory‎,‎ and scientific writing‎.‎
