The abundance, accessibility and value of limpets as a source of food and bait for coastal peoples have resulted in their high frequency in shell middens worldwide. The limpet Patella vulgata is found in middens from the Mediterranean to Norway, and morphometric and sclerochronological analyses of its shell can provide insight into harvesting patterns and paleoenvironmental variables valuable in reconstructing climate. Previous work with P. vulgata has relied on lines on the exterior of the shell, or on lines exiting on the shell surface in shell cross-section, as annual or sub-annual markers. Shell damage may compromise these lines and limit the use of some shells, but growth lines are also found in the better-preserved shell apex. We investigated whether the growth lines in the apex of P. vulgata from two locations in Northern Europe are annual using calcein-marking and recapture. Investigations were performed at one site in the Shetland Islands (UK) and at one site at the northern limit of P. vulgata's range in Northern Norway. We also used laser ablation to measure the concentration of minerals in the shells of two individuals from Shetland to determine if patterns of minerals suggested as bioproxies for temperature and productivity varied annually. All individuals deposited one growth line in the apex during their year in the field, and the lowest ratios of Sr/Ca and Ba/Ca and to a lesser extent Mg/Ca were coincident with annual lines on the shells from Shetland. Growth at both sites was modelled using the von Bertalanffy growth function, and apex growth was nearly five times faster in Shetland than in Norway, probably a result of differences in temperature between the two locations.  相似文献

Recent contributions provide researchers with a useful toolbox to estimate counterfactual distributions of scalar random variables. These techniques have been widely applied in the literature. Typically, the dependent variable of interest has been a scalar and little consideration has been given to spatial factors. In this paper we propose a simple method to construct the counterfactual distribution of the location of a variable across space. We apply the spatial counterfactual technique to assess how much changes in individual characteristics of Hispanics in the Washington DC area account for changes in the distribution of their residential location choices.  相似文献

This article presents an overview of the Hemerdon China Clay Works, 6 miles north-east of Plymouth (Devon), active from c.1860 to 1942. Based on research commissioned in advance of an extension to Headon West Quarry, it describes the development of the clay works and the methods of clay extraction and processing. Archaeological survey recorded a broad range of structures, features, earthworks and artefacts. They included the remains of an engine house of c.1907, two large masonry bases (probably associated with the flat rod system that transferred power from the engine) and a rocker beam. The article also describes a group of mica drags and settling tanks built c.1907. Combining this evidence with that gleaned from documentary sources, notably the large-scale Ordnance Survey mapping, an exceptionally detailed narrative has been constructed of the work's development through time. It has a relevance beyond the particular, and will help the future interpretation and management of the china clay extraction sites that are so characteristic of the region.  相似文献

In her recent book, Virtus Romana, Catalina Balmaceda provides a fascinating analysis of the concept of virtus in Roman historiography. Although virtus, which translates as courage or more generally as virtue, meant different things to different Roman historians, Balmaceda shows that disagreement was never about whether historians should provide readers with examples of virtue. Historians' differences of opinion focused rather on where such models were to be found and what they should look like. This review essay summarizes Balmaceda's main arguments, raises a question about historians' own virtus, and draws some implications from the book for the study of scholarly personae. Did the persona of the historian as a public moralist, such as is known from nineteenth‐century Europe, originate in ancient Rome?  相似文献

There have been legions of individual studies of the history of the English/British/United Kingdom parliament, which is not surprising, since its history is widely acknowledged to be so closely bound up with the history of the nation state itself. But there have been remarkably few attempts to put the story together, to try to consider the long‐term development of parliament as an institution. What would such a story look like? This essay discusses some of the critiques of the whiggish narrative of constitutional and parliamentary development to recognise a common theme in whiggism's tendency to anthropomorphise parliament, to describe it as a single organism with agency and purpose. To forgo that temptation, however, makes it difficult to provide a satisfying narrative of parliament over time. The essay tries to imagine how one might construct a history of parliament as an institution which no longer sees it as an actor in its own story, but, instead, a complex collection of ideas, processes, customs, and conventions, which competing forces struggle to organise in order to achieve their goals, and which is also an arena and forum for that competition.  相似文献

A.F. Pollard*     
A.F. Pollard is now better remembered for founding the Institute of Historical Research than he is for his scholarship. In his heyday, however, Pollard was a formidable and prolific historian, primarily of parliament and the Tudor period. Pollard has been characterised both as a modernist and as a whig historian. Rejecting romantic invocations of liberty, he extolled instead the sovereign nation state, pinpointing the 16th century as the moment when it was achieved. Pollard rejected anachronistic accounts of parliament's development: for him, the assembly had grown by accident (out of the medieval king's council), rather than by design. This adaptability had ensured parliament's longevity and would preserve it into the future. Pollard revered the English parliament all the more for its embodiment of this national good fortune. Pollard helped to professionalise the discipline of history, but his own writings could be found wanting when measured against the standards that he had advocated. Criticism of his approach and assumptions comes easily now. Yet, upon reacquaintance, historians of parliament may find enduring interest in Pollard's shrewd and extensive work.  相似文献

To claim that Hayden White has yet to be read seriously as a philosopher of history might seem false on the face of it. But do tropes and the rest provide any epistemic rationale for differing representations of historical events found in histories? As an explanation of White's influence on philosophy of history, such a proffered emphasis only generates a puzzle with regard to taking White seriously, and not an answer to the question of why his efforts should be worthy of any philosophical attention at all. For what makes his emphasis on narrative structure and its associated tropes of philosophical relevance? What, it may well be asked, did (or could) any theory that draws its categories from a stock provided by literary criticism contribute to explicating problems with regard to the warranting of claims about knowledge, explanation, or causation that represent those concerns that philosophy typically brings to this field? Robert Doran's anthologizing of previously uncollected pieces, ranging as they do over a literal half‐century of White's published work, offers an opportunity to identify explicitly those philosophical themes and arguments that regularly and prominently feature there. Moreover, White's essays in this volume demonstrate a credible knowledge of and interest in mainstream analytic philosophers of his era and also reveal White as deeply influenced by or well acquainted with other important philosophers of history. White thus invites a reading of his work as philosophy, and this volume presents the opportunity for accepting it as such.  相似文献
