Elements of scientific inquiry, such as data or the results of analyses can become objectified, or capable of being adopted and/or adapted by users from multiple disciplinary realms. These objects often provide a bridge for collaborative endeavors, or are used as tools by individuals pursuing multi-disciplinary work. Boundary object terminology was first formalized and applied by social scientists. However, few examples of the application of this useful framework are found in the hydrologic literature. The construct is applied here to identify and discuss how common researcb products and processes are used both internally and externally through providing examples from a project examining the historical and paleo proxy-based hydroclimatology of a headwaters region of Mongolia. The boundary object concept is valuable to consider when conducting and critiquing basic research, collaborating across multiple disciplinary teams as when studying climate change issues, as an individual researcher working in a cross boundary sense using methods from differing disciplines to answer questions, and/or when one group adapts the work of another to their own research problems or interpretive needs, as occurred with selected products of this project.展开更多

The authors provide an overview of current uses and bene?ts of and challenges to resilience and vulnerability concepts for disaster risk management(DRM). The article summarizes the evolution of these concepts and of attempts to de?ne them precisely,and addresses the potential bene?ts of conceptual vagueness.The usage and conception of resilience and vulnerability within a selection of strategies and legislations in DRM are compared. Complementing this analysis of disaster risk research and management practice, a survey identi?es some of the bene?ts of and challenges to the concepts of resilience and vulnerability as seen by a peer-community. Synthesizing the three approaches, we conclude that a certain conceptual and methodological ‘‘haze’’ prevails, which hampers the transfer of information and ?ndings within disaster risk science, from science to practice, and vice versa. But this vagueness offers opportunities for communication between disaster risk science, policy, and practice. Overall, evaluations of the resilience and vulnerability concepts are lacking, which demands the development of criteria to identify and assess the challenges to and bene?ts of resilience and vulnerability for DRM.展开更多
