This orientation to scholarship underscores the need to conduct research in real-world settings, and highlights the ideas that: (1) Policies and programs constitute natural experiments, i.e., planned interventions for people and institutions (Lerner, 1995); and (2) the evaluation of such activities becomes a central focus of applied developmental research Fisher & Osofsky, 1997;Fisher, Rau, & Colapietro, 1993;Lerner, Fisher, & Weinberg, in press).…”
