Reassessing a Theory of Professional Expertise: A Cross-National Investigation of Expert Mental Health Social Workers

This paper presents the findings from a cross-national studyof expert mental health social workers in Melbourne, Australiaand San Jose, California, USA. In this study, expert socialworkers were selected based on a peer-nomination process andthey were invited to participate in two-hour focus group interviewsin which they described memorable practice situations. Detailedaccounts of these practice situations were gathered from nineteenAustralian and American expert practitioners employed in community-basedmental health settings. The study findings corroborate manyof the dimensions that are explicated in a theory of professionalexpertise developed by Fook et al. (2000). Further, the findingsdescribe the skilful and ethical comportment of these socialworkers in the context of often complex and challenging practicesituations. Narrative accounts are used to demonstrate the distinguishingdimensions and features of expert practice described by Fookand her colleagues, especially when providing services to peoplewith chronic mental illness. In-depth articulation of practiceexpertise using cross-national data enhances social work researchand pedagogy by providing important exemplars that inform morefully the development of empirically based practice theories.     

The Roles of Worker Expertise,Information Sharing Quality,and Psychological Safety in Manufacturing Process Innovation: An Intellectual Capital Perspective

This paper examines the roles of three elements of intellectual capital in implementing process innovations. Building upon prior literature, we develop a model describing how worker expertise, information sharing quality, and psychological safety work together as elements of the human, structural, and social dimensions of intellectual capital to influence the technical success of manufacturing process innovation (MPI) projects. Results of an analysis of data describing 179 MPI projects in US firms strongly support a multidimensional, process‐oriented view of intellectual capital's effects on MPI project technical performance. We also find that the incrementalness of an MPI project plays a moderating role over the relationship between worker expertise and MPI performance. Our study provides insights on how intellectual capital can be more effectively accumulated in a project environment.
