The original fineness of coins is very important information that can help us to understand the commercial situation in a wide historical context. This paper deals with a comparison of analytical methods suitable for the evaluation of the actual and original fineness of coins based on a detailed case study of a medieval coin sample. Both non‐destructive (i.e., scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, X‐ray fluorescence, atomic force microscopy and hydrostatic weighing) and destructive (i.e., inductively coupled plasma – mass spectrometry and the Volhard titration method) techniques were used. The original fineness can be also deduced from knowledge of the internal structure of the coin (limited miscibility of copper and silver). A new analytical method based on a combination of a micrograph of the metallographic cross‐section with consequent image analysis was developed for determination of the original fineness. The proposed approach is relatively simple and provides reliable values. Sample heterogeneity and its impact on the determination of fineness are also discussed. 相似文献

In the context of global warming, changes in extreme weather and climate events are expected, particularly those associated with changes in temperature and precipitation regimes and those that will affect coastal areas. The main objectives of this study were to establish the number of extreme events that have occurred in northeastern New Brunswick, Canada in recent history, and to determine whether their occurrence has increased. By using archived regional newspapers and data from three meteorological stations in a national network, the frequency of extreme events in the study area was established for the time period 1950–2012. Of the 282 extreme weather events recorded in the newspaper archives, 70% were also identified in the meteorological time series analysis. The discrepancy might be explained by the synergistic effect of co‐occurring non‐extreme events, and increased vulnerability over time, resulting from more people and infrastructure being located in coastal hazard zones. The Mann Kendall and Pettitt statistical tests were used to identify trends and the presence of break points in the weather data time series. Results indicate a statistically significant increase in average temperatures and in the number of extreme events, such as extreme hot days, as well as an increase in total annual and extreme precipitation. A significant decrease in the number of frost‐free days and extreme cold days was also found, in addition to a decline in the number of dry days. 相似文献

Improvements in Archaeomagnetic Dating in Western Europe from the Late Bronze to the Late Iron Ages: An Alternative to the Problem of the Hallstattian Radiocarbon Plateau

We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies. 相似文献

An error dating from 1885 in mapping the upper Strickland River, Papua New Guinea, was reinforced and extended by government officer Charles Karius in 1929 when reporting results from a lengthy exploratory patrol. Detailed maps produced by the US Army and the Royal Australian Survey Corps in, respectively, 1942 and 1966 perpetuated these errors. It was not until 1979, with release of a series of 1:100,000 topographic maps, that long-standing errors were finally put to rest. Throughout these years, the contributions of well-informed people tended to be ignored in favour of the opinions of those whose status implied authority. 相似文献

The Marseton #2 site is a Weaver ring midden in the Mississippi Valley of Mercer County, Illinois, that was buried by a catastrophic flood event a few centuries after the site had been abandoned. Analysis of the more than 740,000 ceramic items from the village provides insights as to Weaver interactions with other non-Weaver early Late Woodland groups of the region. While the presence of non-Weaver ceramics at the village might represent trade items, or vessels manufactured by potters peacefully or forcibly brought to the site, it is suggested that a non-Weaver household producing Levsen-like ceramics was coexisting at Marseton #2 alongside multiple Weaver households. 相似文献

It has been amply demonstrated that individuals' reproductive capability is the key explanatory phenomenon for understanding onomastic disappearance during the early modern period. This article analyzes the evolution and consequences of surname extinction in a specific population: Catalonia in the sixteenth and seventeenth centuries. In this article two aspects are examined. First, the observed disappearance of surnames is estimated through historical data collected in the Llibres d'Esposalles (Marriage Books) from 1481 to 1600 at Barcelona Cathedral. Second, the estimated natural extinction of those surnames registered in 1481 is forecast by applying a statistical branching process. 相似文献

This study aims to analyse the problem of Vico’s religiosity, still a subject for debate, in the European tradition of universal historiography. Vico’s historical reconstruction has traditionally been considered as orthodox and apologetic. The Neapolitan philosopher, in his major work, New Science, tried to defend not only the historical veracity and authority of biblical narratives as the only source to reconstruct the initial phases of history, but also the temporal and spatial frame of historia salutis, confuting the thesis of a greater antiquity of pagan nations. Nonetheless, it is difficult to conclude that Vico’s historical reconstruction followed the same route of the apologists of his time. Vico demolished not the temporal and spatial sphere, but the unitary frame of historia salutis. In Vico’s setting, all nations formed their civilizations in an autochthonous way and developed them autonomously with diverse timetables. Vico introduced the concept of the plurality of history. In this way, the Neapolitan philosopher contributed to the process of secularization of universal history in a completely different way from his contemporaries. 相似文献

This article offers a re-contextualization of the Positivism Dispute between the Frankfurt School and advocates of empirical sociology in the German sociological profession between 1954 and 1970. Investigating the reasons why the German Sociological Association convened in Tübingen in October 1961, it assigns a more peripheral role to Karl Popper and this now famous seminar. Focusing instead on the debate among German sociologists from the mid-1950s which prompted the convention of the seminar and the invitation for Popper to speak, the article maintains that philosophy of history was the central concern of the Positivism Dispute. In this debate, members of the Frankfurt School emphasized contingency in history and society, while sociologists such as René König, Helmut Schelsky, Ralf Dahrendorf, and Arnold Gehlen advocated sociology as the empirical study of ‘given’ social facts. By doing so the article questions the narrative of the Positivism Dispute advanced by Karl Popper and some of his followers, as well as interpretations which have focused on debates during the aftermath of the Tübingen seminar in the 1960s. 相似文献

This paper examines the diversity of uses of Adam Smith’s ideas in nineteenth-century American debates about the tariff. Legislative debates about American trade policy ran almost uninterrupted from the 1820s to the end of the century; as a result, they provide an abundance of examples of the ways in which legislators marshaled economic ideas to shape political discourse and influence policy. Smith’s causal ideas about free trade and its effects were referenced in policymaking, and Smith’s intellectual authority was often invoked as a legitimating device for partisan ideology. These uses, I argue, contributed to the sloganizing of Smith as the ‘apostle of free trade’ and his enduring popularity as a political icon in American politics. 相似文献
