Advancing Multilevel Research Design
指出多数定量研究只关注自上而下的跨层关系，忽视了自下而上的涌现过程，提出用计算建模等直接定量方法研究涌现机制，并说明间接与直接方法如何互补以推进组织研究。
Multilevel theory and research have advanced organizational science but are limited because the research focus is incomplete. Most quantitative research examines top-down, contextual, cross-level relationships. Emergent phenomena that manifest from the bottom up from the psychological characteristics, processes, and interactions among individuals—although examined qualitatively—have been largely neglected in quantitative research. Emergence is theoretically assumed, examined indirectly, and treated as an inference regarding the construct validity of higher level measures. As a result, quantitative researchers are investigating only one fundamental process of multilevel theory and organizational systems. This article advances more direct, dynamic, and temporally sensitive quantitative research methods designed to unpack emergence as a process. We argue that direct quantitative approaches, largely represented by computational modeling or agent-based simulation, have much to offer with respect to illuminating the mechanisms of emergence as a dynamic process. We illustrate how indirect and direct approaches can be complementary and, appropriately integrated, have the potential to substantially advance theory and research. We conclude with a set of recommendations for advancing multilevel research on emergent phenomena in teams and organizations.
