No, not all of the AS studies are longitudinal (Pilivain is snapshot, people get confused because it was conducted over a 2 month period but there were 103 micro studies within it)
Holistic studies:
Thigpen and Cleckley (looked at different ways in trying to cure eve)
Wiktrom (looked at situational (crimogenic environments) and disposotiional ways (low morality) to explain turning to crime)
