We study complexity of methods using rigid variables, like the method of matings or the tableau method, on a decidable class of predicate calculus wi th equality. We show some intrinsic complications introduced by rigid variables. We also consider strategies for increasing multiplicity in rigid-variable methods, and formally show that the use of intelligent strategies can result in an essential...

Nowadays, university students suffer from a broad range of problems, such as educational underachievement or the inability to control themselves, that lead to procrastination as a consequence. The present research aimed at analyzing the determinants of decisional procrastination among undergraduate students and at assessing a path model in which self regulated learning strategies mediated the r...
