This research sought to develop a structured methodology for transferring resilience resources and safety innovation across industrial sectors, specifically, from aviation to maritime. As transportation sectors struggle to adapt to new economic realities and seek to prosper in new operational contexts there is a need to preserve resources and invest in change initiatives which will derive meaningful impact. A structured methodology to guide a principled transfer of safety solutions across sectors would be a sustainable method of improving the resilience of the sector. An action research approach was adopted. A five-step methodology was developed in cooperation with three maritime organisations to identify challenges and resilience resources from aviation which could be feasibly transferred and implemented. Five steps were identified as being key to a principled transfer of resilience resources from aviation to maritime. They were as follows: (1) industry comparison and database of aviation resilience resources; (2) maritime user needs and gap analysis, and resilience resources evaluation and selection; (3) scenarios production and resources mapping onto scenarios; (4) feasibility analysis; and (5) implementation plan. The results highlight the utility of combining bottom-up (identifying problems) and top-down (identifying a database of resources) approaches at the outset. A comprehensive workshop-based feasibility analysis is also key to ensuring the identified resources can be effectively implemented in the destination sector. [ABSTRACT FROM AUTHOR]

We have detected in Cassini spacecraft data the signature of the periodic tidal stresses within Titan, driven by the eccentricity (e = 0.028) of its 16-day orbit around Saturn. Precise measurements of the acceleration of Cassini during six close flybys between 2006 and 2011 have revealed that Titan responds to the variable tidal field exerted by Saturn with periodic changes of its quadrupole gravity, at about 4% of the static value. Two independent determinations of the corresponding degree-2 Love number yield k2 = 0.589 + 0.150 and k2 = 0.637 ± 0.224 (2σ). Such a large response to the tidal field requires that Titan's interior be deformable over time scales of the orbital period, in a way that is consistent with a global ocean at depth.
