The JEM is developed by combining expert scores and light measurements.
Light measurements
Light intensity during daytime work hours 06:00-17:59 for 1-7 days was measured among 695 workers representing 71 different jobs. Daytime light measurements were collected all year round in Denmark. Back-transformed all daytime all year estimate (lux) based on means of the 12 month- and 12 hour β-estimates.
Expert score:
Three experts rated probability and duration of outdoor work for all 372 jobs within DISCO-88. Their ratings were used to construct an expert score that was included together with month of the year and hour of the day as fixed effects in the model. The expertes ratede the exposure on the following scale: 0 (0 % probability + 0 h), 2 (1–24% + 1–2 h), 3 (25–50%+1–2 h or 1–24% + 3–4 h), 4 (25–50% + 3–4 h), 5 (25–50% + >4 h or >50% + 3–4 h), and 6 (>50% + >4 h).
Coding Specification
BLUP estimate with blank DB07 codes indicate BLUPs for DISCO-88 whereas BLUP estimates with indications of DB07 indicate BLUPs for industries nested in DISCO-88. BLUPs for either DISCO-88 or DISCO-88 and DB07 are taken into account for each calculation of the indicated all daytime, all year light intensity (lux) estimates.
Some Disco88 codes are listed more times (e.g 1221). This means that we have an estimate for that Disco88 code with and without the additional estimate(s) from one or more DB07 codes. The all daytime all year light intensity (lux) estimate listed where DO07 is missing is then the back-transformed all year all day mean (geometric mean) light intensity for the Disco88 code 1221 without taking industry into account. The all year all day mean listed for Disco88 1221 where DB07 is 813000 is the back-transformed all year all day mean light intensity for Disco88 code 1221 taking industry 813000 into account.
