Two recent books provide varied resources for exploring ethical issues in the social sciences. Reflection on ethical issues aims to sensitize scholars to a range of consequences of their research, and to scholars' responsibilities to their discipline, their colleagues, and the public. This review article assesses the utility of these texts (and of…

This commentary expands on the idea of units of cross-linguistic…

Three recent books take up different positions in the on-going debate about how, and out of what, to construct a theory of second language (L2) acquisition. Johnson (2004) advocates a "dialogically based approach", inspired by Vygotsky's sociocultural theory and Bakhtin's "dialogized heteroglossia", with which she would replace what she views as a…

Reviews two textbooks that introduce generative research on second language acquisition and evaluate existing proposals about the role of universal grammar. Comparison of the two texts provides an opportunity to examine conventions the field uses in representing itself to a novice readership. (Author/VWL)

Reviews two guides on the Child Language Data Exchange (CHILDES) project, both of which provide tools for analyzing talk. (Author/VWL)
