This questionnaire was used to gather information on residence characteristics and resident behaviors related to Finf, including building type, presence/use of air conditioning (AC), window opening, and use of air filters/cleaners.
We linked the cohort with the Danish Civil Registration System (Pedersen et al, 2006), which holds information on residence and vital status of all residents in Denmark, and with the Danish National Health Service Register (Olivarius et al, 1997), which provided information on the names and addresses of the GPs with whom the children were listed at the time of diagnosis.
Our second method relies on the fact that when information on residence location is obtained by questionnaire, it is likely that most residents will be able to remember at least the city, town, or village of the residence, even if they are not able to remember the full address.
Notes: 1 In the case of cause-specific admissions, information on residence was available allowing the analyses to be restricted to those resident in the Nicosia district; the same was not possible for all-cause admissions as only aggregated data were available.
We also cannot distinguish multiple hospitalizations for one individual from those for several individuals, and we did not have information on residence locations at times other than at hospitalization.
Disaggregated information for Denmark and Finland circa 1960 and 1970 was not available, so I exploit information on residence permits for Denmark and on main language used for Finland.
Hydraulic tests and tracer tests were made between the two holes to obtain information on connections in the plane of the fracture and to obtain information on residence time distributions in different paths (channels).
In addition, information on residence times of CWD in different decay classes would be very helpful to forecast its dynamics and to calculate the input and output of different decay stages in order to conserve specific habitats of dead wood dependent species (Kruys et al. 2002; Ranius et al. 2003).
Second, information on residence history is unavailable.
Information on residence is provided by the Population Register.
