Title: Existence of shift basic sequences and its implications

Abstract: It is shown that every seminormalized sequence with no weakly convergent subsequences admits a wide-(s) subsequence which is shift equivalent. Also, basic sequences with shiftable properties are studied. They give rise to a generalized form of the Pelczynski's property (u), called property (su). It is shown that every Banach space with a conditional spreading basis has property (su). As a consequence the classical James’ space J2 has property (su), which nicely contrast with the fact that it does not have Pelczynski's property (u).
