Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

ABSTRACT Energy requirements (ER) are known to decline as dogs age into the senior stage. However, the implications of body composition and physical activity (PA) on this parameter remain poorly investigated. The aim of this study was to evaluate ER, body composition, water turnover rate (WTR), and voluntary PA by triaxial accelerometers in adults (5.2

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Ostensive communication in great apes: The evolution of Gricean intent
I discuss the evolution of ostensive behaviours (behaviours that display the communicative intent to influence others through the perception of signals and actions addressed to them). Ostensive communication evolved out of evolutionary adaptations to the challenges and opportunities created by the evolutionary scenario of the meeting of ...
