Transcript of "Seriously Mixed Methods - a GRIDy Challenge?"

  1. 1. © University of Essex18-Dec-02 Seriously Mixed Methods & Digital UK Data A GRIDy Challenge? Dr Ben Anderson www.essex.ac.uk/chimera/
  2. 2. © University of Essex chimera Why bother? • Data Triangulation: • different data on the same individuals • different instruments and methods • Patterns (what?) and explanations (why?) • Grounded theorising • Time and geography • behaviour over time • behaviour in specific locations
  3. 3. © University of Essex chimera An example: Interviews Shadowing & Observation Digital Ethnography Phone call records PC/Internet usage logs Questionnaires Time-use diaries Rich contextual picture Quantitative Qualitative
  4. 4. © University of Essex chimera Wave 1 Wave 2 Wave 3 GB ‘pilot’ Longitudinal Panel • GB panel (2500 individuals) 1998/9 20012000 2002 • Analysis ongoing • BT research contract with ISER (Essex) • 3 waves of surveys and time-use diaries • ownership, usage, social networks, employment, education, demographics • Continuous call records, Internet usage logs and Qualitative interviews from/with the same households/individuals
  5. 5. © University of Essex chimera Visualisation: Mixed Method Data Male (left) and female (right) mean telephone call duration for individuals over 55 and living alone in March 1999 using continuous call records 3D Helix representations of integrated behavioural and survey data
  6. 6. © University of Essex chimera Data Mining: ISP Calling • Base = 323 Households, records for 9 weeks starting January 1st 1999
  7. 7. © University of Essex chimera (Social) Telephony Networks • Source = Jan - April 1999 call records for 343 households from the HoL Panel. • Who’s calling whom? • Which groups of households call each other • Why?
  8. 8. © University of Essex chimera Combining surveys and ethnography • Qualitative finding: telephone calls get shifted in households with children • Calls get made between lunch and school home time and not at all in the early evening • Does the time-use data support this? • Sort of. 0.00 0.20 0.40 0.60 0.80 1.00 1.20 00:00 01:00 02:00 03:00 04:00 05:00 06:00 07:00 08:00 09:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 23:00 Time of Day Meanminutesperdayspentmakingcalls Women aged 20-55 living in households w ith no children under 16 (n = 125) Women aged 20-55 living in households w ith at least one c hild under 16 (n = 104) Mean minutes per day spent making calls at specific times of the day by women who live in households with or without children aged under 16, derived from HoL Wave 1 time-use diary data.
  9. 9. © University of Essex chimera Longitudinal mixed method data: a multimedia database problem? Sample surveys (t=1 to n) PSTN call records Qualitative interviews (transcripts, photos, objects, video clips, social network diagrams) Internet application usage logs (email, web, e- commerce, IM, a/v streaming) Household @ t=1 Individual Household @ t=2 Household @ t=? ? ? N = 2,500
  10. 10. © University of Essex chimera Scaling it up: Digital UK Data Census data PSTN call records Qualitative data (ESRC, commercial, private) Internet application usage logs (email, web, e- commerce, IM, a/v streaming) Mobile usage (voice and data) records, with location data ONS/ESRC/EU Sample and cohort surveys Commercial datasets Research/policy questions Real time applications N = 58,789,194 Medical, govt, tax records
  11. 11. © University of Essex chimera A GRIDy Challenge? • Federated social and behavioural databases • extremely heterogeneous • multiple owners and access rules (public, private, govt) • potentially huge datasets • Realtime aggregation and retrieval • context sensitive • Real time and ‘offline’ analysis
