Spanish Armada pottery

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.     

Non-invasive on-site method for thickness measurement of transparent ceramic glazes based on depth from focus

Glazed ceramics are a common material analyzed through geochemistry, whether in the form of tableware collected during excavations or tiles observed as part of architectural features. Within the framework of these studies, measuring the thickness of the transparent glaze is one of the useful variables available for the characterization of the ceramic, contributing to searches for provenance as well as serialization. However, this task often requires invasive methods performed in the laboratory, which may not always be possible. This paper develops a non-invasive and portable on-site system for measuring the thickness of ceramic glazes. Based on the depth from focus technique, this method makes use of a classical camera, a macroscopic lens, a translation stage, and a laptop for system control. In this article, we test this method through the measurement of glaze for ten samples as compared to results obtained for sections through scanning electron microscopy.     

Designing a New Civic Economy? On the Emergence and Contradictions of Participatory Experimental Urbanism

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.     

Evaluating the Impacts of Nitrate Vulnerable Zones on the Environment and Farmers’ Practices: A Scottish Case Study

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.     

The study of spatiotemporal patterns integrating temporal uncertainty in late prehistoric settlements in northeastern Spain

This paper explores the integration of two variables that are typically difficult to use in spatial analysis: time and uncertainty. A framework is constructed to analyse mid- and long-term variation in settlement dynamics during late prehistory in northeastern Spain. Following previous proposals, an aoristic model is built with ceramic dating to feed a Monte Carlo simulation that explores the case study using a discrete time-step approach. At the same time, available radiometric dating is used to validate the accuracy of the simulation results. Departing from the static analysis of spatial variables, the model proposes a new approach by which researchers can address temporal uncertainty. The results show that patterns detected by classical spatial analysis can be produced by artefacts derived from the division of time in chronological units instead of discrete time periods. The model is also used to compare a priori identical variations whose rate of change, when analysed with this approach, is revealed to be completely different.     

Self-Ownership and Moral Relations to Self in Early Modern Britain

Summary

This paper scrutinises early modern thinking about our moral relations to ourselves. It begins by reiterating the too-often-ignored point that full self-ownership was not a position defended in Britain—by Locke or anyone else. In fact, the actual early modern positions about the moral relations we have to ourselves have been obscured by our present-day interest in self-ownership. The paper goes on to organise the moral history of the self by examining the reasons available for prohibiting self-harm. Those reasons typically had their source in God, self, and others. Major divisions in the period arose over which kinds of reasons could be invoked and why. The defining feature of this intellectual landscape was the debate between ‘other-regarding’ and ‘dignity’ theorists, who differed over the moral status of the self and over its importance as a source of moral reasons. More dramatically and controversially, various freethinkers and sceptics questioned the importance of God as a source of prohibitions for self-harm. After offering an interpretation of this history, the paper concludes by noting some connections and contrasts between early modern and present-day moral and political philosophy on the moral status of the self.     

The chert from the Castelltallat Formation (south-central Pyrenees): archaeometric characterisation and archaeological implications

Chert from the limestones and marly limestones of Castelltallat Formation (Ebro Basin) was widely used throughout prehistoric times in north-eastern Iberia to produce stone tools due to its properties and accessibility. A rough estimate indicates that this rock—either as raw material or as lithic products—was distributed mainly to the north of the outcrops, over an area of 6000–8000 km². However, other rocks in the area have similar characteristics which can lead to confusion in the interpretation of its prehistoric use and distribution. In order to establish useful archaeometric criteria for differentiating this chert from other similar, the Castelltallat chert is characterised in petrographic, mineralogical and geochemical terms. The chert nodules are found to be homogenous at the macroscopic and microscopic level, with a significant presence of bioclasts, thus indicating they might be formed in a freshwater lake environment by the early diagenetic replacement of carbonates in shallow waters. The mineralogical composition is homogeneously uniform and of a flint type, characterised by an almost exclusive predominance of quartz, without any opaline phases, and a variable proportion of moganite. The iron oxide content is very low, whereas its chemical composition is unusually high in uranium which correlates positively with carbonate content and negatively with silica. Archaeometrical parameters are provided to reach a proper identification of tools knapped with this chert. This way, chert from Castelltallat Formation turns out to be a valuable lithological marker to evaluate the range of mobility of the human groups who lived in the north-eastern Iberia and their contacts with neighbouring areas.
