This document contains four symposium papers on linking human resource development (HRD) theory and practice. "Reorienting the Theoretical Foundations of Human Resource Development: Building a Sustainable Profession and Society" (Tim Hatcher) examines the theoretical disciplines of economics, general systems, sociology, psychology, and ethics in terms of their currency to HRD and the extent that they influence societal outcomes. "Towards a Philosophical Framework for Thought and Practice" (Wendy E. A. Ruona, Susan A. Lynham) proposes a framework for HRD thought and practice that emphasizes a systems perspective of philosophy. "The Need for Theoretical Model Building in HRD" (Tom Shindell) discusses the lack of conceptual clarity and definition in the field of HRD and identifies ways theoretical model building can facilitate conceptual clarity and definition in HRD (facilitating development of a unifying definition of HRD, identifying gaps in HRD research, delineating the field's boundaries, indicating directions for future research, and enabling further dialogue and reflection in HRD). "Bridging the Gap with a Multidimensional Performance Model" (Susan Reynolds Fisher, Catherine M. Sleezer) offers a model that defines three levels of performance (capacity, process, accomplishment) at four levels of the organization (individual, group, organization, industry). (MN)
