Female firefighters showed significantly lower survey ratings on overall satisfaction, perceived comfort, and performance of their turnout pants.
Downward continuation highlights the high frequency content of a gridded magnetic data set, just as if the data had been acquired at a lower survey height.
Several recent studies have also challenged the presumption that lower survey response rates imply lower survey accuracy [ 14].
For example, in the general population more sensitive topics lead to lower survey response rates [ 8].
There is also evidence from a number of countries in Europe for lower survey response rates in other capital cities (J Mindell, personal communication).
Others have also reported lower survey participation rates among persons who engage in risk behaviours such as smoking, alcohol or drug use [ 22].
In general, forest and farmland sites had lower survey effort per unit of area relative to urban sites, although time spent surveying was usually longer.
However, this may be less useful in metropolitan areas that generally have the lower survey response rates associated with a younger demographic, higher migrant populations, and therefore more non-native speakers, and greater deprivation, associated with lower literacy levels.
