Vietnam has had a national Payments for Forest Environmental Services (PFES) policy in place since 2010, which transfers money for forest protection from water and energy users to households who live in upland watersheds. However, despite a loose resemblance to general Payments for Ecosystem Services (PES) principles, implementation in Vietnam differs strongly from a theoretical ideal, and has a number of unique features, including: strong state involvement in transactions; no use of markets to set payments; poor definition and monitoring of ecosystem services; and the adoption of non-conditional incentives that strongly resemble livelihood subsidies for poor rural areas. The form that PES takes in Vietnam has been shaped by institutional histories of forest management that have envisioned a strong role for the state and for financial transfers to the rural uplands. At the same time, PES has also been influenced by active engagement and agency of central and local government actors, and local payment recipients, and key areas in which they have impacted PES design include shared governance and more equitable benefit distribution models. These institutional priorities and local values that have shaped PES policy and implementation in Vietnam have led to a hybrid model, full of contradictions and compromises, that neither fits a classical definition nor resembles neoliberal conservation outcomes, and whose success is difficult to judge. 相似文献

The focus of this study is the analysis of a trepanation performed on the skull of an adult male from the famous Bell Beaker necropolis of Ciempozuelos (Madrid) excavated at the end of the 19th century. The unusual characteristics of the pottery and other associated grave goods gave rise to the use of the name ‘Ciempozuelos’ to define the regional Bell Beaker style; this refers to similar finds from other sites on the Meseta of central Spain. Although trepanations from Chalcolithic contexts in the Iberian peninsula are not infrequent, they are unusual in Bell Beaker inhumations. Furthermore, this skull is exceptional not only for the type of trepanation performed, but also for the subsequent cranial deformation apparently resulting from the operation, as well as evidence of a second subsequent trepanation which indicates a very short post‐surgical survival period for the individual.

During excavations at Quseir el-Qadim on the Red Sea coast, the body of a Roman cat was recovered. The skeleton is nearly complete and remains of the fur, stomach, and lower intestinal tract are also preserved. This animal was a very large and heavily built male domestic cat. Shortly before his death, the cat had eaten at least six rats (Rattus rattus), remains of which were found in the stomach and in the dung balls. 相似文献

The bone mineral content (BMC) was measured using a special dual-photon scanner in 25 mandibles with normal macroscopic and radiographic bone structure. The mandibles were excavated from two Norse sites in Greenland, which date to the first and last part of the medieval Norse settlement period, respectively. The main purpose of this study was to investigate whether there was a change in BMC levels between the early and the late settlement period. The results showed no difference in male BMC between the early and the late site material. A statistically significant gender difference was found, analogous to most clinical and archaeological BMC studies. The sample did not allow testing for age-related, especially female postmenopausal-related, bone loss. It is known that Eskimos generally have a very low BMC, probably the effect of a high-protein marine diet. The lack of decrease in BMC levels for the Norse could indicate that they did not increase their overall protein intake over the 500-year settlement period. Other studies (both archaeological and anthropological) point to an increased reliance on marine foodstuffs throughout the settlement period. Thus, if the Norse increased their reliance on marine foodstuffs, they probably did not do so to the extent of an almost exclusive marine diet like that of the Eskimo. © 1997 John Wiley & Sons, Ltd. 相似文献
