Lecture One: Introduction to Research
Methodology and Design
• Definition of key terms
• The structure of knowledge
• Essential attributes of research
Antonio Gramsci
• An Italian political scientist (Marxist), most well
known for his theories on civil society vs. political
society.
– he said “the point of modernity is to live a life without
illusions while not becoming disillusioned”.
– modernity is a rejection of the traditional in favour of
the principles of the Enlightenment (reason and
analysis)
– why is this relevant to research methodology?
• what is research?
• what is (scientific) knowledge?
• what is reality?

Key Definitions
• What is RESEARCH?
– An activity whose purpose is the generation of new
knowledge by means of scientific method(s)
• In more detail …
– Frascati Manual (OECD); research and experimental
development comprises creative work undertaken on a
systematic basis in order to increase the stock of
knowledge, including knowledge of man (sic), culture
and society, and the use of this stock of knowledge to
devise new applications

Questions
Theory and Practice
• Theory is when you know everything but nothing
works
• Practice is when everything works but no one knows
why
• In our lab, theory and practice are combined.
Nothing works and no one knows why.
8
Induction vs. Deduction
• Induction is the development of argument from the
specific to the general (or theoretical)
• Deduction is the development of argument from the
general to the specific
9
Key Definitions 2
• What is RESEARCH METHODOLOGY?
– body of knowledge which attempts to explain/understand
(and hence develop structure for) ‘how research is done’
– the various steps that are generally adopted by a
researcher in studying his research problem (method)
together with the associated logic (what and why)
• What is RESEARCH METHOD?
– the specific process or steps followed by researchers in
undertaking research (experimental design, data collection,
etc)
• What is RESEARCH DESIGN?
– the overview or plan of the actual steps (c.f. the architect’s
drawings of a house vs. the builders steps)
10
Key Definitions 3
• What is ONTOLOGY?
– the (philosophical) study of the categories of being (reality)
and the relationships between them (ontology of NSI or
knowledge)
• What is EPISTEMOLOGY?
– the philosophical study of the nature and scope of
knowledge (e.g. traditional vs. scientific)
• What is TELEOLOGY?
– the notion of root cause or objectives; it is an account of a
given activity’s or object’s purpose OR a definition of an
object or activity based on its purpose (e.g. a car is a form
of transport)
11

Teleology
Method
Process
Ontologies
• The dominant ontological claims:
– positivism; that there exists are single reality which is
constant in time and independent of human experience or
the observer
– constructivism; that there exist multiple realities
dependant on the observer (in the extreme form there is
no such notion as an objective reality)
– critical realism; that there multiple versions of the
‘knowledge of reality’ but only a single reality
13
Philosophical Origins of the
Bifurcation
• Ludwig Wittgenstein (1889-1951); “scientific
evidence”
– all knowledge claims must be verifiable in experience
independent of the observer
– founder of logical positivism
• Martin Heidegger (1889-1976); “being in the world”
– research cannot be conducted independent of the
observer
– founder of constructivism
14
Assumptions of the Experimental
Scientific Method (Positivist)
• A belief that there is some kind of ORDER which will
be revealed (come to understand) through research
• External reality exists which is a shared or public
reality
• Human perception and intellect is reliable (our
senses can record and measure)
• Parsimony or simplicity is the ultimate aim
• Generality is possible; we can generalise from the
particular to the world at large
15
Cohen and Manion 2000
A Comparison of Epistemological
Paradigms
Positivist Constructivist
Reality is single, objective and
apart from the observer
Reality is subjective and multiple
Quantitative data derived from
experiment
Qualitative data derived from
observation
Reliability is most important
(repeatable results)
Validity is important (improved by
triangulation)
Deductive Inductive
Location is artificial; all variables
held constant except the
independent variable
Location is natural; not possible
to control any variables
Mainly experimental, preferably
with control
Type of research includes
ethnographic, participant
observation, case studies
16
The Praying Mantis
• Observation: in certain conditions (laboratory), the
female mantis will eat her mate
• Interpretation:
– male researchers: the praying mantis, with its forelegs
folded as if in prayer, may look pious, but its mating ritual
is truly a macabre affair. Once the smaller male is attached
to the female's body, she decapitates him, but he
continues the act of conjugation for several more days
before he dies and is eaten by his voracious mate.
17
Female Researchers
• Yes, the female praying mantis does sometimes eat her mate.
In fact, male mantises will often offer themselves up as food to
the female during the mating process, and from a biological
standpoint this action makes sense. There's no point to mating
with a female who might die from a lack of food before she can
lay her eggs and pass the father's genes onto the next
generation.
• In some instances, she'll even behead the poor chap before
they've consummated their relationship. As it turns out, a male
mantid is an even better lover when his brain, which controls
inhibition, is detached from his abdominal ganglion, which
controls the actual act of copulation. But most instances of
sexual suicide in mantids occur in the confines of a laboratory
setting. In the wild, scientists believe the male partner gets
eaten less than 30% of the time.
18
Several Types of Research Design
• Qualitative vs quantitative vs mixed methods (see
Lecture 2)
• Types of designs
– Experimental
– Surveys
– Case studies
– Ethnographic studies
– Evaluation research
– Participatory action research (actually a separate
paradigm)
19
Essential Attributes in Research
• Marais defines three necessary dimensions of
research:
– Teleological (describe, explore, explain/understand)
– Constituent (conceptualisation, hypothesis, observation
and communication)
– Epistemic (internal and external validity, reliability,
‘replicability’, objectivity)
• Most research can be judged on the extent to which
the three dimensions have been satisfied (was the
objective clear; has the due process been follow; is
the knowledge of a suitable quality?)
20
Reference
• Marais, H. 2012. A Multi-Methodological Framework
for the Design and Evaluation of Complex Research
Projects and Reports in Business and Management
Studies. The Electronic Journal of Business Research
Methods, 10(2), pp 64-76.
21
Epistemic Attributes (Positivist)
• Internal Validity: the degree to which the changes in
the dependent variable are indeed due to the
independent variable (is the relationship causal?)
• External Validity: the extent to which the results are
generally applicable (outside the sample population)
• Reliability: the extent to which the research finding
can be repeated by the same researcher/experiment
• Replicability: the extent to which the findings can be
repeated by another researcher (also objectivity)
22
Attributes (Modern)
Traditional construct Underlying issue Replace with
Internal validity Truth value Credibility
External validity Applicability Transferability
Reliability Consistency Dependability
Objectivity Neutrality Confirmability
23
Academic Research vs. Management
Study
Aspect Academic Research Management Study
External
validity
The results can be applied more
widely than the unit of research
(company or individuals)
The results are only valid to the
specific company or individual
Theory Builds new theory or tests existing
theory
Applies theory but at a
simplistic level
Source of
background
knowledge
Mostly recent peer-reviewed
literature
Mostly trade articles and other
management studies
Teleology Seeks causative relationship Focussed on improvements and
results
Methodology Seeks novelty (insights) Replication of proven formulas
for success
24
Class Work
• Fill in three dimensions of the line below
25
Scientific
Knowledge
Faith
Evidence is important
Sentiment (how it makes you
feel) is important
Objectivity is important
Test Yourself
• There appear to be two opposing epistemological positions on the
relationship or interdependence between science, society and the
individual:
– relativism which situates science as merely one socially constructed way
of knowing among others of equal validity
– realism, which accords science a greater status as a universally true body
of knowledge.
• Realism has been cast as ignoring the influence of social factors on
science. Relativism has been pronounced to be impractical and
ignorant of the existence of many fundamental laws which are
observable independent of the observer.
• Explain the debate between the two epistemological viewpoints, why
relativism is considered impractical and suggest how a compromise
may be possible.

Antonio Gramsci • An Italian political scientist (Marxist), most well known for his theories on civil society vs. political society. – he said “the point of modernity is to live a life without illusions while not becoming disillusioned”. – modernity is a rejection of the traditional in favour of the principles of the Enlightenment (reason and analysis) – why is this relevant to research methodology? • what is research? • what is (scientific) knowledge? • what is reality? 4

  • 6. Key Definitions • What is RESEARCH? – An activity whose purpose is the generation of new knowledge by means of scientific method(s) • In more detail … – Frascati Manual (OECD); research and experimental development comprises creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of man (sic), culture and society, and the use of this stock of knowledge to devise new applications 6
  • 7. The Construction of Knowledge 7 Theory Observation Deduction Analysis and Interpretation Hypothesis Data Collection Research Design Induction Research Design Research Questions
  • 8. Theory and Practice • Theory is when you know everything but nothing works • Practice is when everything works but no one knows why • In our lab, theory and practice are combined. Nothing works and no one knows why. 8
  • 9. Induction vs. Deduction • Induction is the development of argument from the specific to the general (or theoretical) • Deduction is the development of argument from the general to the specific 9
  • 10. Key Definitions 2 • What is RESEARCH METHODOLOGY? – body of knowledge which attempts to explain/understand (and hence develop structure for) ‘how research is done’ – the various steps that are generally adopted by a researcher in studying his research problem (method) together with the associated logic (what and why) • What is RESEARCH METHOD? – the specific process or steps followed by researchers in undertaking research (experimental design, data collection, etc) • What is RESEARCH DESIGN? – the overview or plan of the actual steps (c.f. the architect’s drawings of a house vs. the builders steps) 10
  • 11. Key Definitions 3 • What is ONTOLOGY? – the (philosophical) study of the categories of being (reality) and the relationships between them (ontology of NSI or knowledge) • What is EPISTEMOLOGY? – the philosophical study of the nature and scope of knowledge (e.g. traditional vs. scientific) • What is TELEOLOGY? – the notion of root cause or objectives; it is an account of a given activity’s or object’s purpose OR a definition of an object or activity based on its purpose (e.g. a car is a form of transport) 11
  • 13. Ontologies • The dominant ontological claims: – positivism; that there exists are single reality which is constant in time and independent of human experience or the observer – constructivism; that there exist multiple realities dependant on the observer (in the extreme form there is no such notion as an objective reality) – critical realism; that there multiple versions of the ‘knowledge of reality’ but only a single reality 13
  • 14. Philosophical Origins of the Bifurcation • Ludwig Wittgenstein (1889-1951); “scientific evidence” – all knowledge claims must be verifiable in experience independent of the observer – founder of logical positivism • Martin Heidegger (1889-1976); “being in the world” – research cannot be conducted independent of the observer – founder of constructivism 14
  • 15. Assumptions of the Experimental Scientific Method (Positivist) • A belief that there is some kind of ORDER which will be revealed (come to understand) through research • External reality exists which is a shared or public reality • Human perception and intellect is reliable (our senses can record and measure) • Parsimony or simplicity is the ultimate aim • Generality is possible; we can generalise from the particular to the world at large 15 Cohen and Manion 2000
  • 16. A Comparison of Epistemological Paradigms Positivist Constructivist Reality is single, objective and apart from the observer Reality is subjective and multiple Quantitative data derived from experiment Qualitative data derived from observation Reliability is most important (repeatable results) Validity is important (improved by triangulation) Deductive Inductive Location is artificial; all variables held constant except the independent variable Location is natural; not possible to control any variables Mainly experimental, preferably with control Type of research includes ethnographic, participant observation, case studies 16
  • 17. The Praying Mantis • Observation: in certain conditions (laboratory), the female mantis will eat her mate • Interpretation: – male researchers: the praying mantis, with its forelegs folded as if in prayer, may look pious, but its mating ritual is truly a macabre affair. Once the smaller male is attached to the female's body, she decapitates him, but he continues the act of conjugation for several more days before he dies and is eaten by his voracious mate. 17
  • 18. Female Researchers • Yes, the female praying mantis does sometimes eat her mate. In fact, male mantises will often offer themselves up as food to the female during the mating process, and from a biological standpoint this action makes sense. There's no point to mating with a female who might die from a lack of food before she can lay her eggs and pass the father's genes onto the next generation. • In some instances, she'll even behead the poor chap before they've consummated their relationship. As it turns out, a male mantid is an even better lover when his brain, which controls inhibition, is detached from his abdominal ganglion, which controls the actual act of copulation. But most instances of sexual suicide in mantids occur in the confines of a laboratory setting. In the wild, scientists believe the male partner gets eaten less than 30% of the time. 18
  • 19. Several Types of Research Design • Qualitative vs quantitative vs mixed methods (see Lecture 2) • Types of designs – Experimental – Surveys – Case studies – Ethnographic studies – Evaluation research – Participatory action research (actually a separate paradigm) 19
  • 20. Essential Attributes in Research • Marais defines three necessary dimensions of research: – Teleological (describe, explore, explain/understand) – Constituent (conceptualisation, hypothesis, observation and communication) – Epistemic (internal and external validity, reliability, ‘replicability’, objectivity) • Most research can be judged on the extent to which the three dimensions have been satisfied (was the objective clear; has the due process been follow; is the knowledge of a suitable quality?) 20

  • 22. Epistemic Attributes (Positivist) • Internal Validity: the degree to which the changes in the dependent variable are indeed due to the independent variable (is the relationship causal?) • External Validity: the extent to which the results are generally applicable (outside the sample population) • Reliability: the extent to which the research finding can be repeated by the same researcher/experiment • Replicability: the extent to which the findings can be repeated by another researcher (also objectivity) 22
  • 23. Attributes (Modern) Traditional construct Underlying issue Replace with Internal validity Truth value Credibility External validity Applicability Transferability Reliability Consistency Dependability Objectivity Neutrality Confirmability 23
  • 24. Academic Research vs. Management Study Aspect Academic Research Management Study External validity The results can be applied more widely than the unit of research (company or individuals) The results are only valid to the specific company or individual Theory Builds new theory or tests existing theory Applies theory but at a simplistic level Source of background knowledge Mostly recent peer-reviewed literature Mostly trade articles and other management studies Teleology Seeks causative relationship Focussed on improvements and results Methodology Seeks novelty (insights) Replication of proven formulas for success 24
  • 25. Class Work • Fill in three dimensions of the line below 25 Scientific Knowledge Faith Evidence is important Sentiment (how it makes you feel) is important Objectivity is important
  • 26. Test Yourself • There appear to be two opposing epistemological positions on the relationship or interdependence between science, society and the individual: – relativism which situates science as merely one socially constructed way of knowing among others of equal validity – realism, which accords science a greater status as a universally true body of knowledge. • Realism has been cast as ignoring the influence of social factors on science. Relativism has been pronounced to be impractical and ignorant of the existence of many fundamental laws which are observable independent of the observer. • Explain the debate between the two epistemological viewpoints, why relativism is considered impractical and suggest how a compromise may be possible. 26
