摘要
<正>The last 50 years have witnessed tremendous changes in both research and publication practices within the context of an increasingly market-oriented higher education system."The period has also witnessed the growth of collaboration and multiple authorship; the expansion of access to a massive online literature and the fragmentation and specialization of research"(p. xiii). All these changes have exerted significant impact on discursive practices and the way academics write. This book, Hyland and Jiang (2019b), based on the same three corpora of leading journals in four disciplines at three points (1965, 1990 and 2015) in time, attempts to trace language variation and change in published academic writing over the past 50 years by taking a diachronic discourse analytical perspective.
