A note on the "hidden" material below : Each section of this guide includes – beside the common readings – three subsections, one for an analytical task , one for recommended readings , and one for related readings . To simplify navigating through the course guide, only the headings for these subsections are initially visible. The content of all these subsections are hidden (so that the beginning appearance of the page is similar to a standard syllabus) until the viewer clicks on the subsection heading, then its contents will appear. While this organization is helpful for negotiating the page most of the time, it can become an obstacle if we want to search the page (for example, for a particular article) as searches will ignore the hidden material. To overcome this limitation, it is possible to show all the hidden sections by clicking the § symbol at the top of the page (and simply reload the page to collapse all the "hidden" sections to their usual look). The table of contents at the top of the page will still work to aid speedy navigation to any section.
