Interpretive-Historical research 2. Qualitative research 3. Correlational research 4. Experimental research 5. Simulation and modelling research 6. Logical argumentation 7. Case studies and combined strategies Groat and Wang deals with all these – We will look closely at 5 (in bold) of the 7 1. Interpretive Historical Research • History into vie wre ssoemarecthh ibnrgin fgrosm the past • Interpretation • Narrative • “sIct hiso lfarorsmh ihpi sthtoarti cthael world hofa fso toatkneonte tsh,e s oauprpcaer atus rbeibfeliroegnrcaepsh,y a, nwdh ich validate what is stated.” (Groat and Wang 2013, p.194) 16/08/2016 16 Tactical concerns in history research (Groat and Wang 2013, p.195) 2. Qualitative research • “embracing interpretation, meaning in context, interaction and the quality of the commonplace”. (Dana Cuff quoted in Groat 2013 and Wang, p. 215) • Qualitative researchers study things in their natural settings, attempting to make sense of or interpret phenomena in terms of the meanings people bring to them. • Open ended questions – Exploring – Responses shape questions as understanding grows 16/08/2016 17 Key components of qualitative research • Emphasis on natural settings • A focus on meaning interpretation and • Am afokceu sse onns eh oowf t hreesirp oowndne nts circumstances • The use of multiple tactics – Structured interviews • Significance of inductive logic – dRaetsae iasr ccohl lqeucetesdtions evolve as – It is NOT exclusively inductive Other features of qualitative research (Groat and Wang 2013, p.223) 16/08/2016 18 Tactics employed in qualitative research Data Collection (Groat and Wang 2013, p.244) Tools and techniques • Interview plans • Recording – Transcripts • Coding – Looking for patterns, themes • Visualising NVIVO for Windows By OSR Available for students at RMIT My Desktop (Groat and Wang 2013, p. 250) 16/08/2016 19 3. Correlational research • rSeelaetkiosn tsoh iidpesn btiefytw een variables – oOuftteconm seeesk bsa tsoe pdr eodni ctht eth e observation of key variables • For example – Ibdeetnwteifeyn t hteh er eulasetio onfs ah ispp ace saenadt ipnagr,a omr eatcecres sssu tcoh as fsaumnosuhsi nsteu d(yW oilfl iNamew W Yhoyrtke o’su tdoor sWpaancge s2 i0s1 d3e, spc. r2ib6e3 )in Groat and Another example • Relating commercial office rents to green building ratings – (Eichholtz, Kok & Quigley 2010) “The results suggest that an otherwise identical commercial building with an Energy Star certification will rent for about 3 percent more per square foot; the difference in effective rent is estimated to be about 7 percent. The increment to the selling price may be as much as 16 percent.” (Eichholtz, Kok & Quigley 2010, p.2508) (Eichholtz, Kok & Quigley 2010, p.2503) 16/08/2016 20 Relationship between timing of risk control decisions and quality of risk control (US and Australian data) 39 0.00 1.00 2.00 3.00 4.00 5.00 0.0% 20.0% 40.0% 60.0% 80.0% 100.0% Mean HOC score Percentage of risks controlled in the pre-construction stage Case HOC Linear (Case HOC) (r=.737, p=.000). (r=.737, p=.000). Tools and tactics Collecting data • Deciding what to measure – Often easy for economic variables – Can be difficult for spatial variables – Use of a space – Activity on a construction site • Questionnaires – Structured collection study participants of data from • Observation – Time-lapse photography – Making notes • Key considerations – Representativeness – Cwiadne rI ceoxtnetnedxt ?my findings to a Used with permission Lyrian Daniel 2016 16/08/2016 21 Analysing the data • Use of graphs – Graphical representation of data – Plotting variables can identify relatio inns ah iXpsY chart • Use of statistics – dSetavteislotipc aml toodoelsls can help – Common tools – Linear regression – Multivariate linear regression • Software – MS Excel – IBM SPSS – Tableau Problem! Correlation analysis does not deal effectively with causation 4. Experimental research • Defining characteristics: • The use of an independent variable – (Tmhea nvipaurilaabteled )is b oyf ttehne creosnetraorlclehde r – cFloimr eaxtea mchpalem: bTehre temperature in a • oTuhtec ommeea svuarreiambelenst of one or more – Variables of interest are measured – For example, thermal sensation – “Am I hot, cold or neutral” • Focus on causality – Isolating causes • cEoxnpfeinriemde tnot athl em leatbh o(bdust aarree nhoatr der to execute in the field) Building Services Engineer 1973 JIHVE 1970 16/08/2016 22 Experimental design • ‘Tests to investigate any relationship(s) between carried out and the resultant outcomes’ (Fellows &th eL uai,c t1iv9i9tie4s) • dTeop eesntdaebnlist hv acraiaubslaels r e(Blartyiomnasnh,i p2 0b0e4tw)een independent and • IV manipulated; all other variables held constant • gSruobujepcsts randomly assigned to experimental and control • Control Group – no experimentation • Rarely used in social/organisational research – Impractical – Ethical ‘minefield’ – Expensive Control Group Experimental Group Experiment NO Experiment Random assignment Sample 16/08/2016 23 Multiple baseline experimental design A Superintendent Foremen 1 2 3 4 5 6 7 8 9 10 11 12 A B C D Time (Months) A.

To experiment means to actively change {x} to observe the response of {y}.” (Groat and Wang 2013, p.345) • Experimental methods require ‘reduction’ – The method requires that complex systems must be represented by simple parameters – Imagine trying to prove causation of ‘Good management’ to ‘employee productivity’ – How does one control ‘good management’ 16/08/2016 24 5. Simulation research • Copying reality – Creating worlds in which experiments can be undertaken • Commonly used in conjunction with the experimental approach – Controlling independent variables, and measuring output variables is easier in simulated worlds • Challenges: – How accurately does the simulation represent reality? – What’s missing from the simulation? – What simplification has been made? 6. Logical argumentation • Thinking through a problem – Outlining principles – Defining relationships – Extrapolating outcomes • Undertaking the ‘thought experiment’ Groat and Wang 2013, p.385 16/08/2016 25 7. Case studies and combined strategies • “A case study is an empirical investigates a contemporary pinhqeuniorym tehnaot n within its real life context…” (Robert Yin quoted in Groat and Wang 2013, p.418) • Key attributes – cFoonctuesx tosn single or multiple cases studied in real life – Capacity to explain causal links – The importance of theory development – A reliance on multiple sources of evidence – The power to generalise theory • qCuaasnet istatutidviee sd actaan be based on qualitative data or Case studies Groat and Wang 2013, p. 441 16/08/2016 26 Select a number of Cases to study Multiple observations in the Cases - compare Rival Propositions Propositional Framework (Theoretical Template) In vivo  2013, Architectural Research Methods, 2nd edn, Wiley, Chichester.
