The malleable nature of both the idea of a city and the idea of resilience raises an important question—why measure?Resilience is assumed to be located in the physical infrastructure of specific places or as a quality of the people located *** disasters,we are often trying to conceptualize,measure,or render legible resilience in physical *** what is it that we are trying to measure,and is the idea of a city reflected in these measurements?If cities are organized around something other than resilience,is resilience their natural by-product?What is necessitating the need for increased—and measured—resilience?Using interpretive policy analysis,we explored five well known disaster resilience frameworks(UNDRR's Making Cities Resilient Campaign,UN-Habitat's City Resilience Profiling Programme,The World Bank and gFDRR's Resilient Cities Program,Arup and The Rockefeller Foundation's City Resilience Index,and The Rockefeller Foundation's 100 Resilient Cities)to identify the working definition of‘‘city''and of‘‘resilience.''We conclude that if the demand for cities to become more resilient is an acknowledgment of the risk produced by globalized urbanization,then the call itself is an indictment of the current state of our cities.

Sleep is an essential behavior that is conserved in most animal species. Two molecular mechanisms regulate sleep： circadian clocks for the timing of sleep, and a homeostatic process for the amount of sleep [1]. The fruit fly, Drosophila melanogaster, exhibits robust sleep behavior and serves as an excellent model in which to study the neuronal and molecular mechanisms of sleep.

In previous years, IUgS conducted a programme in the area of geoscience Education and Training. The programme was organised under the status of a Working group or a Commission. The IUgS level of activities in past years in geoscience Education （COgEOED） was generally low and so the IUgS Executive Committee considered this body dormant. The IUgS Strategic Planning Committee recommended in its report that, ＇Technology-transfer and geological education focusing on developing countries should continue to be key-activities of the IUgS＇.
