Hubristic leaders over-estimate significantly their own abilities and believe their performance to be superior to that of others; as a consequence, they make over-confident and over-ambitious judgements and decisions. The fact that hubristic leaders tend to be resistant to criticism, and invulnerable to and contemptuous of the advice of others further compounds the problem. In this article, we review conceptual, theoretical and methodological aspects of hubristic leadership research. We examine hubristic leadership from two standpoints: first, from a psychological and behavioural perspective, we review hubris in terms of over-confidence and its relationship to core self-evaluation and narcissism; second, from a psychiatric perspective, we review hubris as an acquired disorder with a distinctive set of symptoms (Hubris Syndrome), the onset of which is associated with the acquisition of significant power. In doing so, we draw distinctions between hubris and several related constructs, such as over-confidence, narcissism, core self-evaluation and pride. Methodologically, we review how hubris and Hubris Syndrome can be recognised, diagnosed and researched, and we explore some of the unique challenges and opportunities hubris research presents. We conclude by offering some directions for future inquiry and recapitulate the practical and pedagogical significance of this vitally important but under-researched leadership phenomenon

Abstract-The Virtual Museum of the Pacific is a digital ecosystem implemented as Web 2.0 application that experiments with information and knowledge acquisition for a digital collection of museum artifacts from the Australian Museum. The Virtual Museum of the Pacific allows several search methods: attribute search based on a control vocabulary, query refinement and query-by-example but importantly it facilitates a number of social media interfaces that enable content to be added and tagged, the control vocabulary to be extended, user perspectives to be defined and narratives added via wiki. We characterize the design of the Virtual Museum of the Pacific as: a semantic Web application with a Web services back-end, and as a digital ecosystem by identifying its purpose, function and stakeholders. In doing so, the paper illustrates the issues encountered in its design and deployment, the technical platform, the historical context of the growth of the collection and the challenges to the organization and management of a digital ecosystem metadata model.
