a. Developed for this paper Brief description of<br />

criteria for realism<br />

research<br />

b. Major authors<br />

c. ONTOLOGY<br />

1. Ontological<br />

appropriateness<br />

Research problem<br />

deals with complex<br />

social science<br />

phenomena involving<br />

reflective people<br />

d. 2. Contingent validity Open, 'fuzzy<br />

boundary' systems<br />

(Yin 1994) involving<br />

generative<br />

mechanisms rather<br />

than direct cause-<br />

e. EPISTEMOLOGY<br />

3. Multiple perceptions<br />

of participants and of<br />

peer researchers<br />

f. METHODOLOGY<br />

4. Methodological<br />

trustworthiness<br />

g. 5. Analytic<br />

generalisation<br />

h. 6. Construct validity<br />

and-effect<br />

Neither value-free nor<br />

value-laden, rather<br />

value-aware<br />

Trustworthy - the<br />

research can be<br />

audited<br />

Analytic<br />

generalisation (that<br />

is, theory-building)<br />

rather than statistical<br />

generalisation (that<br />

is, theory testing)<br />

Case study<br />

techniques<br />

within the<br />

realism<br />

paradigm<br />

Selection of<br />

research<br />

problem e.g. it is<br />

a how question<br />

In depth<br />

questions;<br />

iterative search<br />

for cognitive<br />

mechanisms.<br />

Multiple<br />

interviews,<br />

supporting<br />

evidence, broad<br />

questions before<br />

probes,<br />

triangulation.<br />

Papers accepted<br />

through peer<br />

review<br />

Case study<br />

database, use of<br />

quotations in<br />

report.<br />

Identify research<br />

issues before<br />

data collection<br />

to formulate<br />

interview<br />

protocol.<br />

Theoretical and<br />

literal<br />

replication.<br />

Criteria for case<br />

research<br />

Yin (1994)<br />

Internal validity<br />

Reliability<br />

External validity<br />

through the<br />

specification of<br />

theoretical<br />

relationships,<br />

from which<br />

generalisations<br />

can be made<br />

Construct<br />

validity<br />
