Regression analyses revealed substantial effects of sojourn goals on measures of sociocultural adaptation. Response surface analyses served to examine the interplay of sojourn goals and respective sojourn experiences on sojourn satisfaction. ...

The concept of sojourn time and a sojourn time operator, aimed at describing the length of time spent by a quantum mechanical system in a given subspace of states, is investigated. A general rigorous definition to the sojourn time operator is given and some of its ... t having nonzero measure. This implies that the sojourn time in Ω never vanishes, and that zero is never an eigenvalue of the sojourn time operator. It is also shown that for ... of sets Ω, including all bounded sets, the sojourn time turns out to be bounded with a ...
