International audience; Fifteen epiphytic lichens, collected near an active nickel mine and along an East-West transect across New Caledonia island (South-West Pacific), were analyzed for their metal contents. The purpose is to evaluate atmospheric metal contamination and the impact of mining exploitation on the surroundings. The structure of the compositional dataset was explored using a covariance biplot. The score of the first principal component was used as a generic indicator to locally evaluate the degree of contamination. This study demonstrates that Ni, Co and Cr are highly concentrated in lichens near mining exploitation.
Building composite indicators in tourism studies: Measurements and applications in tourism destination competitiveness
2017
Abstract Composite indicators are useful tools to synthesize and monitor multidimensional phenomena. The aim of this paper is twofold: to offer the methodological foundations to build composite indicators in tourism and to evaluate a set of currently available composite indicators. Tourism destination competitiveness indicators constitute the object of this contribution. Their definitions, concepts and measures are analyzed and their evaluation is performed through the application of an original protocol. The results highlight that several methodological issues still surround the measurement of destinations competitiveness indicators. This paper provides tourism scholars and practitioners w…
