Colin Martin has been associated with the excavation of Armada ships for four years. In 1968–9 he took part in Sydney Wignall's Spanish Armada Expedition as archaeologist and deputy leader and since 1968 has carried out research into the Armada campaign, particularly in the fields of ship construction and gunnery. In 1971, he worked as archaeologist and project co-ordinator on the wreck of La Trinidad Valencera in Donegal; and during the same year he became Director of the Maritime Archaeological Institute which has been set up in association with St. Andrew's University . 相似文献

La céramique de l'Armada COLIN J. M. MARTIN La classification et l'analyse dc la céramiquc trouvée dans différentes épaves de l'Armada (Girona, S. Maria de la Rosa et Trinidad Valencera) mettent en évidcnce des centres de fabrication (a Séville, Mérida, Lishonne, Saint-Sébostien) de divers types de poterie ibérique dont la forme avait une relation avec le contenu. On relève aussi différentes méthodes utilisées pour fabriquer la cémique vernissée ou non. Trois tessons vernissés à l'aide d'étain et six non vernissés, de couleur rouge, ont été analysés sous l'aspect pétropaphique. On compare la classification de Goggin et les collections de Langouez de Grande-Bretagne. Les archives de Simanca sont utilisées pour dénommer la vaisselle découverte dans cette épave, et qui était officiellement en usage sur l'Armada. 相似文献

Can we remake local economies from scratch – not through political struggle but by design – to solve wicked problems and transform urban governance? Such questions are raised by an emergent trend within urban experimentation that emphasises participation and commoning in designing peer-to-peer provisioning systems through a platform logic. This article deconstructs the discourses animating what we term “participatory experimental urbanism” and reflects on what this might mean for local state restructuring in times of neoliberal austerity. By following its policies and prototypes as they move and mutate across the London Boroughs of Lambeth and Barking & Dagenham, we examine two exemplary initiatives, Open Works and Participatory City, tracing their beginnings in Lambeth's “cooperative council” model and their ongoing assembling into novel public-common-philanthropic partnerships. Foregrounding the contradictions within this latest turn towards urban governance-beyond-the-state, we draw out the implications for the future of social innovation, design-thinking, and the experimental city. 相似文献

Nitrate vulnerable zones (NVZs) have been established throughout Europe to tackle diffuse pollution. This research investigates the attitudes and practices of farmers in the River Eden catchment, within the Strathmore and Fife NVZ in eastern Scotland, and explores how these changed between 2002 and 2011. Attitudes were investigated using interviews; efficiency of nutrient use was evaluated using farm gate nutrient budgets (NBs). Most of the 16 farmers regard NVZ regulations as burdensome and costly; however, attitudes to NVZs became more positive during the period. NBs demonstrated that arable farms generate the least nitrogen (N) and phosphorus (P) surpluses, dairy the most. N efficiency improved on nine farms and declined on two; P efficiency improved on 12 farms and declined on two. Overall, the 16 farms were using 13% less N and 19% less P in 2011 compared with 2003. Water quality data demonstrate that Nitrate N in the catchment's main rivers dropped between 2004 and 2011 by a mean of 15.5%, whereas mean phosphate P declined very little. Legacy P and Inefficient sewerage treatment facilities may explain the latter finding. Results demonstrate that NVZ regulations, combined with economic pressures, have affected farmers’ attitudes and behaviour, resulting in significant improvements in surface water quality. 相似文献
