Introduction

This unit provides an introduction to the evolution of mammals.

We will be considering Darwin's observations on a great many mammals, and how he noticed that species fell into natural groups. We take as an example the evolution of one particularly interesting mammal, the whale, and look at evidence both from fossils and from DNA to see which other mammals are most closely related to whales. We see how the evidence from these two very different sources points to the same relationship and

Pierce Biotechnology
The pedagogical value lies in its concise description of the various analytical derivatization reactions and reagents used for gas chromatography. This site gives a nice description of the various derivatization reagents and what type of analyte they are used for. One of the few, if not the only, ASDL sites dealing with derivatization.

Hydrophilic Interaction Chromatography, HILIC/SEC, HILIC/SXC
This site provides good background and operational parameters for the use of a specific type of chromatography, hydrophilic interaction chromatography. Pedagogical value, however, is probably only directed toward a graduate/advanced course in separations. This document provides a very clear explanation of operational parameters and mode of operation for HILIC. Very readable!

Learning outcomes

On completion of this unit, you should be able to:

  • identify some key themes in discourse analysis;

  • appreciate the consequences of discourse research for some key topics in social science, such as indentity, interaction and subjectivity;

  • be familiar with some discourse analytical techniques and their consequences for analysing social interactions.

Introduction

This unit introduces some of the main themes and issues in discourse analysis. To do this, it looks at extracts from the late Princess Diana interview screened on Panorama in 1995. The interview not only broke the conventions for British Royal appearances, but also reshaped the usual boundaries between public and private for the Royal family. While the focus here may be on Diana's words, the unit is not in itself concerned with the Diana phenomenon. And while some of the points discour
