mind", "having a desirable house", "able to enjoy travelling", "engaging in hobbies" and so on, besides the fundamental desires concerning health, financial stability and independence of children. We are planning to conduct large-scale survey on the generality and importance of these found desires in a fixed format questionnaire.
This outcome containing rich information could be of an support for the validity of the simplified question format that were developed to meet the second purpose of this research.
Concerning the third purpose, we measured the average time spent for composing e-mails for the first and second step. It took on the average 32 minutes as total per participant. The other measure was the number of days used to complete the two-step survey. It took on the average 7.5 days per participant. Efficiency in this regard would increase with the improvement of reminder mails and other means.
Our two pilot studies seem to indicate the practical feasibility of the EGM by email in the computer-network era in which the global community is being restructured at an unprecedented rate. People have started using computers as a vital means of wide communication. E-mail or more advanced technique will soon become an everyday tool. The shortcoming in sampling should not cloud the value of our effort when there is no established theory or procedure for sampling network users.
