Integrated Emergency Response:From Vulnerability to ResilienceProf. David AlexanderUniversity of Florence, Italy
Resilience [Resiliency]:definition: readily recovering  from shock, buoyantthe term is derived from rheology, the  science of the deformationofmatteraswithmaterials, so with society:aimfor the optimum combinationofabilitytoresist and absorbshocksresilience is an amalgam of attitude, preparedness and redundancy.
Attitude: positive outlook
 ingenious approaches
 searching for solutions
 involving other peopleRESILIENCERedundancy expensive but worthwhile
 alternative solutions
 extra capacityPreparedness: emergency plans
 monitoring & forecasting

Vulnerability the potential for harm or losses  (medical, social, economic, psychological) something that is constructed socially
 triggered by hazard impact
 a complex holistic phenomenon composed  of different categories and parts the inverse of capability and resilience.ImpactResponseHazardExposurexVulnerability= Risk

Like friction, vulnerability only exists whenit is mobilised by the application of forces.
