The military justice records of the Armies of Italy and theSambre and Meuse reveal that, despite their contrasting militaryfortunes during the campaigns of 1796–97, their experienceswere very similar in many respects. The records of the conseilsmilitaires of the year IV (1795–96) and the conseils deguerre of the following year reveal both conditions of servicein the two armies and the circumstances and attitudes that regulatedthe relationship between soldiers and civilians in Italy andGermany. The conseils de guerre, instituted to remedy the perceivedlaxity of the conseils militaires, operated on similar principlesto their much-maligned predecessors. Occasional instances ofexemplary severity apart, these conseils frequently mitigatedboth charges and sentences, reserving the full severity of thelaw for soldiers who were not present to receive punishment.The councils protected miscreant soldiers more effectively thanthey did vulnerable civilians, but they nonetheless affirmed,if only in principle, the idea that revolutionary warfare shouldbe contained within legal limits. 相似文献

A Sensitive High Resolution Ion MicroProbe (SHRIMP II) has been used to make high spatial resolution in situ micro-analyses of oxygen isotopes in fish otoliths, and teeth from fossil herbivores and a Neanderthal. Large intra-tooth variations in the oxygen isotopic composition (up to 9‰) were observed in the enamel of herbivores from the Neanderthal fossil site of Payre, consistent with preservation of seasonal cyclicity. The range of isotopic compositions observed in Neanderthal tooth enamel was much smaller (∼3‰), possibly the result of a longer enamel maturation time averaging out variability. An archaeological otolith from a Preceramic site in Northern Peru exhibited marked changes in δ18O over life, due either to the fish occasionally migrating from the sea to a lower salinity habitat, or to short-lived rises in sea water temperature. A fish otolith from Australia's Willandra Lakes World Heritage Area showed clear seasonal variations, but also a general trend towards isotopically heavier and more saline water, as indicated by higher δ18O and Sr/Ca values resulting from increased evaporation. The results of these case studies are compared to results of oxygen isotope analysis using more conventional methods and demonstrate the ability of the SHRIMP II to provide precise high spatial resolution in-situ oxygen isotope analyses of a variety of biogenic materials. This approach has major advantages over conventional methods. It can provide rapid, micro-scale isotopic analyses of sub-permil precision without the need for chemical preparation of the sample. 相似文献

The suitability of imagery from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA series of satellites for the synoptic classification of circulation trends in the European Arctic is assessed with reference to data from three climate stations. Simplified synoptic cyclonic classifications are derived from the satellite imagery and tested against climate data. Five classes of frontal system are derived from the tracking of systems over the UK‐Scandinavia‐Baltic region using 1460 satellite images over two years. An index based on the qualitative interpretation of satellite imagery was related to the reference data. The tracking of the systems in the imagery also facilitates a comparison of travel times across the region and the frequency of occurrence. Frontal systems that remain largely stationary over the Baltic were found to correlate best with precipitation at the reference sites. The paper thus investigates the use of AVHRR imagery for the categorisation of weather patterns towards deriving quantitative relationships between circulation classes and weather elements (such as temperature and precipitation) where, for example, climate data are sparse or where skills required for the interpretation of Height Potential Fields are lacking. 相似文献

This paper explores the interaction between fieldworker and “tradition bearer” over an extended period of time, in the context of an ethnographic study of singing traditions in the southern Pennines of England. Using examples, it examines the negative as well as the positive aspects of the exchange, with particular emphasis on mutuality and reciprocity. It charts the development of key relationships and the ways in which they have come to maturity and achieved equilibrium. Careful thought is given to the role of the fieldworker in respect of active/passive, interventionist/non-interventionist stances. Aspects of performance, commercialisation, networking, promotion, and media relations are discussed. Following a consideration of ethical and moral issues, including exploitation and advocacy, the paper suggests a working model of partnership as a way forward for future productive field-based research into traditional expressive arts. 相似文献

The railway machine‐ensemble was brought to the classical condition by applying rational management, and associated techniques, which were developed by F.W. Taylor, F.B. Gilbreth, and H.L. Gantt. These methods identified the Stephenson‐Goss archetype, operated on the Common User system, as the ideal form of locomotive for the steam operated railway. It is argued that when a system is brought to the classical condition it usually approaches Design Impasse, and obsolescence. The application of rational methods to the machine‐ensemble is related to the creative, derivative, and synthetic traditions of engineering design. 相似文献

Frederick G. Scott's World War I war memoir, The Great War As I Saw It, contains the sole unofficial eyewitness recording of a court martial execution that we possess. The case of William Alexander 20726, executed in October 1917, for desertion in the face of the enemy compelled Scott to devote more printed space to it than to the death of his own son, Henry. A discussion based upon a close reading of Scott's memoir and an exposition from archival sources of Alexander's case demonstrates the ways in which Scott evades the case's disturbing implications echoes wider aspects of Canada's early memorialization of the Great War. 相似文献

ABSTRACTThis article considers the status of John Ogilby’s Virgil translations as royalist texts. The paratextual material to the 1649 and 1654 editions provides a framework which invites a royalist reading; the translation promotes this by manipulating Virgil’s text and contemporary typographic conventions. These factors combine in passages that depict the death of kings. The volume follows the Virgilian precedent of foretelling events that had already occurred by presenting the passage on the death of Priam in such a manner to imply that it anticipated Charles I’s execution. This allowed Ogilby to grant a sense of inevitability to the prophecies his translation offers regarding events that he hoped lay in the near future. The 1654 edition subtly draws on Caroline-era royalist literary tropes to suggest a permanent revival of the monarchy under Charles II. Ogilby’s contributions to Charles II’s coronation celebrations draw on the Virgil translations in vindication of such prophecies. 相似文献
