This book updates the theory and brings together empirical research based on the multidimensional entrepreneurship–professionalism–leadership (EPL) framework for subjective career ‘space’. It also discusses the extension of the original ‘person-centred’ framework to other levels of analysis, for example, ways of considering the EPL (human capital) capacities of an organisation, city, or even nation. By providing insights into the development of EPL motivations and efficacies over time, the book helps readers appreciate the application of the EPL framework in a wider range of contexts, such as research–innovation–enterprise, healthcare, and pre-university settings. It also shows how EPL research contributes to a better understanding of leadership and entrepreneurial development.
