Chapter 2.3 Dimensions of variation in TIME magazine
This chapter presents an analysis of <i>TIME </i>magazine cover stories published between 1923 and 2011. This research applies the Multi-Dimensional framework in two ways: by adding the <i>TIME</i> magazine texts to the five main dimensions of variation defined by Biber (1988) and by extracting the dimensions of variation that are specific to the magazine using a new factor analysis. The chapter also reports on the assessment of the role of external factors on the variation, including editorial changes, and the political, economic, and military events during which the texts were published. Finally, the chapter reveals the text types (i.e. linguistically defined varieties) present in <i>TIME</i> magazine.
