Research Questions and Techniques of Analysis
CADS research projects often focus on research questions of the following types:
Given that P is a discourse participant (or possibly an institution) and G is a goal, often a political goal:
(i) How does P achieve G with language?
(ii) What does this tell us about P?
(iii) Comparative studies: how do P1 and P2 differ in their use of language? Does this tell us anything about their different principles and objectives?
A second general type of CADS research question, which might be asked of interactive discourse data, is the following.
Given that P(x) is a particular participant or set of participants, DT is the discourse type, and R is an observed relationship between or among participants:
How do {P(a), P(b)…P(n)} achieve / maintain R in DT ?
Another common type of research question open to investigation using CADS techniques is the following:
Given that A is an author, Ph(x) is a phenomenon or practice or behaviour, and DT(x) is a particular discourse type.
A has said P(x) is the case in DT(a)
Is Ph(x) the case in DT(b)
This is a classic “hypothesis-testing” research question: we test the hypothesis that whatever practice has been observed by a previous author in some discourse type will be observable in another. It is a process we might call para-replication, that is, the replication of an experiment with either a fresh set of texts of the same discourse type or of a related discourse type, “in order to see whether were an artefact of one single data set” (Stubbs 2001: 124).
A final example of research question which may usefully be investigated using CADS techniques is of the following sort.
Given that P(x) is a participant or category thereof, and LF(x) is a particular language feature:
Do {P(a)} and {P(b)} use LF(x) in the same way?
Such research aims to ascertain whether different participants use a particular linguistic feature in the same or different ways. The research may proceed to attempt to explain why this is the case.

Famous quotes containing the words research, questions, techniques and/or analysis:
“I did my research and decided I just had to live it.”
—Karina O’Malley, U.S. sociologist and educator. As quoted in the Chronicle of Higher Education, p. A5 (September 16, 1992)
“Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.”
—Susanne K. Langer (1895–1985)
“It is easy to lose confidence in our natural ability to raise children. The true techniques for raising children are simple: Be with them, play with them, talk to them. You are not squandering their time no matter what the latest child development books say about “purposeful play” and “cognitive learning skills.””
—Neil Kurshan (20th century)
“Cubism had been an analysis of the object and an attempt to put it before us in its totality; both as analysis and as synthesis, it was a criticism of appearance. Surrealism transmuted the object, and suddenly a canvas became an apparition: a new figuration, a real transfiguration.”
—Octavio Paz (b. 1914)
