Despite major investments in community-based tourism to diversify economies, reduce poverty and improve life quality in the Caribbean, little is known about what conditions lead to resilience and sustainability. Sustainability from a resilience theory perspective is the likelihood an existing system of resource use will persist indefinitely without a decline in social and natural resource bases. Undertaking activities to enhance resilience and sustainability improves a system's ability to persevere, adapt and learn to meet challenges from unanticipated economic, political or natural events. This study investigated six communities in the Commonwealth of Dominica, all part of a seven-year community tourism program, and examined residents' perceptions of the social, institutional, economic and ecological resilience of their community, and therefore the resilience and sustainability of community tourism development. It used a new scale using eight steps suggested by Devellis' scale development methodology. Data indicated moderate to low resilience in all four domains across the communities. This suggests that communities should invest in strengthening social bonds, developing capacity in local institutions, in diversifying the tourism product and controlling infrastructure development. Indicators measuring trust, networks, local control, flexible governance, leakage prevention and controlled infrastructure development emerged as important in assessing social–ecological resilience and sustainability.  相似文献

John Virgo gave generously of himself and expected nothing in return. He inspired the same in others. The world has sadness as well as joy, but while he was here, he made it radiant.  相似文献

Models that assume bonds denominated in different currencies are perfect substitutes can not explain certain empirical puzzles: the exchange rate volatility puzzle is that these models can not explain the observed volatility in real and nominal exchange rates; the Backus-Smith puzzle is that these models can not explain the observed low correlation between real exchange rates and the ratio of home to foreign consumption; the Backus-Kehoe-Kydland puzzle is that these models can not explain the observed low correlation between home and foreign consumption; and finally, the uncovered interest parity puzzle is that these models can not explain the observed deviations from that parity. These long standing puzzles make the models harder to defend. In this paper, we present a symmetric two country portfolio balance model in which home and foreign bonds are imperfect substitutes for money in each country’s transactions technology; this of course makes home and foreign bonds imperfect substitutes for each other. Our calibrated model is capable of addressing the Backus-Smith puzzle and the Backus-Kehoe-Kydland puzzle. It does not fully resolve the exchange rate volatility puzzle, but it makes some headway. And finally it generates deviations from uncovered interest parity, though by some estimates these deviations are not large enough to be consistent with the data.  相似文献
