Materials and methods for the recovery and analysis of microscopic plant remains in underwater archaeology. This article explores formation of underwater sites, preservation and potential contamination of botanical remains, sampling techniques, benefits of sampling and searching for microscopic remains including pollen, phytoliths, cystoliths, starch grains, epidermal tissue, and cellulose fibre, and conservation and archiving of archaeobotanical samples. Materials such as ship's caulking, surrounding sediment matrices, bilge sediments, and organic remains found inside various types of cargo containers can contain microscopic plant remains that become botanical fingerprints used to identify cargoes, ship's foods, onshore vegetation, location of a ship's home port, and plants used to make rope, basketry, and matting. 相似文献

Carbon markets have provided fertile ground for research on the changing nature of political contestation. MacKenzie locates a “techno‐politics” of carbon markets that creates new possibilities for a “politics of market design”. In contrast, Swyngedouw argues carbon markets are part of a “post‐political” shift that narrows potential pathways through “depoliticisation”. This article engages with these debates by examining three recent attempts to reform the ailing European Union Emissions Trading System: restricting industrial gas offsets, backloading allowance auctions and the 2030 climate and energy package. It conceptualises the respective episodes as contests over the reach, force and priority of value determinations in climate policy, emphasising the contradictory imperatives facing states on each issue. The outcomes of contestation between industry groups and environmental organisations—real but limited reforms and a consolidation of the carbon market over alternatives—demonstrate the constraints facing technocratic campaigning and the ongoing politicisation of climate change. 相似文献

In two-dimensional and single axis three-dimensional finite element analyses, the ground motion incidence angle can play a significant role in structural response. The effect of incidence angle for three-dimensional excitation and response is investigated in this paper for response of highway bridges. Single-degree-of-freedom elastic and inelastic mean spectra were computed from various orientation techniques and found indistinguishable for combinations of orthogonal horizontal components. Probabilistic seismic demand models were generated for the nonlinear response of five different bridge models. The negligible effect of incidence angle on mean ensemble response was confirmed with a stochastic representation of the ground motions. 相似文献

Abstract. Devolution to Scotland and Wales has not yet led to popular demand for a new constitutional settlement for England, but it has led to renewed debate about who the English are. One reason why the English find this a difficult question is that there is more than one construction of England with which to engage. This paper distinguishes four constructions, each with its distinctive orientation to time and place: Anglo‐British England, Little England, English England and Cosmopolitan England. Each has its light and dark sides. Each also enjoys considerable currency, but none has an exclusive appeal. Cosmopolitan England may be thought to constitute the future, but the uneven cosmopolitanisation of the regions will continue to complicate the collective representation of England. 相似文献

A Romanesque double-springer and five voussoirs, decorated with foliate carving and pellet, have been reused as a door-head in the ground floor of Church House, Gloucester Cathedral. The carved stones are illustrated, together with a reconstruction of the original double arch, which may have come from an early 12th- century pulpitum screen or the arcade of the first Norman cloister. 相似文献
