Transport corridors can generate both wider economic benefits (WEBs) and costs through their effects on diverse development outcomes. To advance understanding of how corridors could generate WEBs, this paper undertakes a quantitative review and meta-analysis of the literature that estimates the impacts of large transport infrastructure projects. The analysis finds that characteristics of individual studies and the design of the transport infrastructure influence estimated benefits. It also shows that, on average, while corridor interventions tend to benefit economic welfare and equity, they often detrimentally impact the environment. To mitigate trade-offs, policymakers can consider using complementary interventions. 相似文献

Carbon and nitrogen isotope profiles were obtained from incremental dentine analysis of 19 non-adults from a cemetery in Riga, Latvia. The research compared the life histories and diet between people buried in two mass graves and the general cemetery. The δ13C profiles of several children from the mass graves were similar but did not resemble the patterns seen in children from the general cemetery, suggesting that they probably represented a different population group. The rise in δ15N values towards the end of the life of four individuals from one mass grave suggests they were victims of an historically documented famine. 相似文献

In 1992, an archaeological survey of Marawah Island conducted by the Abu Dhabi Islands Archaeological Survey identified two significant Neolithic settlements known as MR1 and MR11. Both sites are constructed on prominent rocky platforms located towards the western end of the island. In 2000 and 2003, small-scale excavations took place at MR11, with the first full excavation taking place in 2004. Excavations continued at MR11 between 2014 up to 2019. Radiocarbon dating demonstrates that the site was occupied between the earliest part of the sixth millennium to the mid-fifth millennium BC. Three areas have been so far examined. Area A—a tripartite house (2004 and 2014–2017 excavation seasons); Area B—a partial structure (in 2003 and 2017–2018); and Area C—a series of at least five rooms (in 2017–2019). The results provide a valuable new insight into the architecture and planning of Arabian Neolithic settlements in the region, as well as the earliest known evidence for pearling. 相似文献

India has one of the world's largest and most significant bodies of rock paintings and engravings, yet not a single rock art site or image has been directly and accurately dated using radiometric techniques. Here we report on results from the Billasurgam Cave complex near Kurnool in southern India. Although this cave complex has been investigated archaeologically since the late 1800s, it was not until 2008 that a large petroglyph, consisting of the remains of three nested diamond designs on a stalactite, was noted. In order to determine if this petroglyph had been made recently, flowstone was sampled from on top of and below the engraving. Radiocarbon dating revealed a mid-Holocene age of about 5000 cal BP for the petroglyph, but we cannot rule out the possibility that the engraving is several centuries younger. Similar nested diamond designs at some rock painting sites and on a chert core elsewhere in India have been assumed to be Mesolithic. Our result is consistent with this hypothesis, although we note that it also consistent with the creation of the petroglyph in the early Neolithic. We conclude that the Billasurgam engraved diamond design was probably made by Mesolithic foragers of the Kurnool region and is the oldest surviving form of rock art yet directly dated in southern India. 相似文献
