We investigate the practices by which bilingual university students in Hong Kong appropriate texts in producing utterances, particularly written texts. Following Wertsch and his colleagues we ask: • To what extent do our students appropriate texts in constructing their own discourses? • What linguistic means do they use to do this? • What can these processes tell us about what they now can do with discourse representation; and • What do we need to teach them? This research shows that our students' writing displays considerable intertextuality and interdiscursivity. Responses to this writing in tutorial sessions indicate that they are skilled at orchestrating the multiple voices within their own discourses. The commonly stated concern that our students do not know how to do quotation and citation correctly is somewhat misplaced and researchers need to move the focus away from the mechanisms of citation and attribution to the social practices of textual appropriation.

This paper explores issues of cultural models in the discourse of public health in a multicultural, multilingual context through a 'frame analysis' of 20 AIDS awareness campaigns aired in both English and Cantonese in Hong Kong from 1987 to 1994. Using a methodology derived from the work of Goffman (1974), and Gee (1990), it examines how the authors of AIDS awareness messages in Hong Kong project cultural models on several different levels of "framing" and how these models both reflect and validate dominant ideologies within the society.

Traditional approaches to the way people react to food risks often focus on ways in which the media distort information about risk, or on the deficiencies in people’s interpretation of this information. In this chapter Jones offers an alternative model which sees decisions regarding food risk as taking place at a complex nexus where different people, texts, objects and practices, each with their own histories, come together. Based on a case study of a food scandal involving a particular brand of Chinese candy, Jones argues that understanding why people respond the way they do to food risk requires tracing the itineraries along which different people, texts, objects and practices have traveled to converge at particular moments, and understanding the kinds of concrete social actions that these convergences make possible.

Using the novel technique of topic modelling, this paper examines thematic patterns and their changes over time in a large corpus of corporate social responsibility (CSR) reports produced in the oil sector. Whereas previous research on corporate communications has been small-scale or interested in selected lexical aspects and thematic categories identified ex ante, our approach allows for thematic patterns to emerge from the data. The analysis reveals a number of major trends and topic shifts pointing to changing practices of CSR. Nowadays ‘people’, ‘communities’ and ‘rights’ seem to be given more prominence, whereas ‘environmental protection’ appears to be less relevant. Using more established corpus-based methods, we subsequently explore two top phrases - ‘human rights’ and ‘climate change’ that were identified as representative of the shifting thematic patterns. Our approach strikes a balance between the purely quantitative and qualitative methodologies and offers applied linguists new ways of exploring discourse in large collections of texts.
