WHITE, M.A., FALKINGHAM, P.L., COOK, A.G., HOCKNULL, S.A. & ELLIOTT, D.A., 2013. Morphological comparisons of metacarpal I for Australovenator wintonensis and Rapator ornitholestoides: implications for their taxonomic relationships. Alcheringa 37, 1 - 7. ISSN 0311-5518.Various comparisons of left metacarpal I of the Australovenator wintonensis holotype have been made with Rapator ornitholestoides. These specimens were identified as being morphologically more similar than either was to that of the neovenatorid Megaraptor namunhuaiquii. Owing to the poor preservation of A. wintonensis and R. ornitholestoides, distinct morphological separation between the two appeared minimal. The recent discovery of a near perfectly preserved right metacarpal I of A. wintonensis enables a direct and accurate comparison with R. ornitholestoides. Distinct morphological differences exist between the metacarpals of the two species. A re-evaluation of the age of the A. wintonensis holotype site (AODL 85 ‘Matilda Site’) with zircon dating reveals a maximum age of 95 Ma, 10 Ma younger than the Griman Creek Formation at Lightning Ridge, from which R. ornitholestoides was recovered. This age difference detracts from the probability that the specimens belong to the same genus.Matt A. White?

The established rhetoric of opposition between state and NGOs as development agents has shifted to one of complementarity and common interest. Along with this, the ‘comparative advantage’ claimed for NGOs has expanded from economic and welfare benefits to encompass also the political goods of civil society and popular participation. This paper reviews these developments in the context of Bangladesh. It argues that they need to be assessed critically in ways which are both theoretically informed and locally contextualized. While recognizing that there are, indeed, areas of common experience and interest between the state and NGOs in Bangladesh, it questions whether these necessarily coincide with the interests of those they all invoke: the poor. 相似文献

Stable carbon- and nitrogen-isotope ratios were measured for segments along the shafts of hair from eight individuals from the site of Pacatnamu, located in the Jequetepeque Valley on the north coast of Peru. All are from known grave contexts dating from Moche (ca. 450–750 A.D.) to Lambayeque periods (ca. 900–1100 A.D.). The mean δ13C and δ15N values of hair segments from individuals are comparable to those of bone, and demonstrate increased consumption of marine resources in the Lambayeque times relative to the Moche period. 相似文献

This article highlights a marked growth in the number of second homes in Ireland since the mid-1990s, which is concentrated in the rural and coastal parts of the peripheral Border, Midwest, Southeast, Southwest and West regions, together with parallel growth in the number of long-term vacant dwellings in these regions. These phenomena are linked to economic and population growth, the “laissez faire” nature of land use planning in rural Ireland, the generous fiscal treatment of housing, as well as tax incentives to encourage house building in economically marginal areas. The social and economic impacts of these dwelling on individual localities vary, depending on their number, usage patterns and the nature of the local economy and housing market. However, their environmental consequences are largely negative as is their impact on the national economy and on the economies of those regions where vacant dwellings are concentrated. Thus, our research questions the value of housing-led rural development, as they can result in excessive output of vacant and second homes and highlights the importance of adequately resourcing planning authorities if the worst excesses of rural housing overdevelopment are to be avoided. 相似文献
