ABSTRACT
The basic data survey would enable the people for the first time to follow in detail the factors that affect the changing level of invocation. Research at the local level for the survey could provide information needed to distinguish between the articulated and ostensible grounds of an invocation and the value goals actually pursued. It would be useful to bring into the survey information about the state, federal, or international units within which the locality is ineluded, since these have immediate effects in the local decision process, especially at the application phase. The survey would occasionally examine the activities of appraisal services in bringing their findings to the attention of community groups and of the public at large. Estimates of damage to a value position depend in part on establishing expectations of their future value position that claimants could have rationally entertained prior to termination.
