Abstract
The Black‐Scholes (B‐S) model in its various formulations has been the mainstay paradigm on option pricing since its basic formulation in 1973. The model has generally been proven empirically robust, despite the well documented empirical evidence of mispricing deep‐in‐the‐money, deep out‐of‐the‐money and, occasionally, at‐the‐money options with near maturities [see Galai (1983)]. Research on explaining the observed pricing anomalies has focused on the variance of the return of the underlying asset, which, in the case of the B‐S model, is assumed to remain invariant over time. The variance term is not directly observable, leading researchers to speculate that pricing discrepancies may be caused by misspecification of this variable. More specifically, interest in the volatility variable has centered about the implied standard deviation (ISD).

Abstract
Purpose
The purpose of this paper is to review the role of social networks in the translation of research into practice, propose a broader model of communities of practice (CoPs) involving practitioners, researchers and service users, and describe a case report which adopts this broader model.
Design/methodology/approach
Using the evidence on both knowledge transfer and the use of CoPs to share practice, this work presents an approach to supporting and developing CoPs around the specific context of an applied research programme in health and social care.
Findings
The development of CoPs across the professional and organisational boundaries of researchers, practitioners, and service users has the potential to enhance the translation of evidence into practice. It requires bringing together the right people and providing a supportive infrastructure to facilitate exchanges. Methods of engaging and involving the different stakeholder groups vary according to the specific context and pre‐existing networks, but developing closer working relationships and sharing common values is an important step in this process. Within the applied health research partnership of the Collaboration for Leadership in Applied Health Research and Care for Nottinghamshire, Derbyshire and Lincolnshire (CLAHRC‐NDL), the role of Diffusion Fellows, Engagement Fellows and CLAHRC Associates provides a way of engaging with its diverse stakeholders.
Originality/value
This paper builds on existing evidence about CoPs and the role of social networks in knowledge transfer.
