At the centre of this article stands a letter written by Abbot Richard of Saint-Vanne sometime during the first quarter of the eleventh century. The letter describes two voyages to the otherworld taken by two monks at the abbey of Saint-Vaast in Arras in 1011 and 1012. A careful reading of the letter reveals that behind what appears to be a standard text, belonging to the very popular genre of otherworld journeys, hides an apocalyptic message of urgent warning that the world is about to reach its end. The letter thus serves as a prooftext for the existence of apocalyptic tension in the period between A.D. 1000 and A.D. 1033, and as such contributes to the ongoing debate regarding the ‘terrors of the year 1000’.  相似文献

Secondary pit deposits in historical occupations of Near Eastern mounds are usually regarded as uninteresting and are seldom analyzed. We used an integrated approach to study all the artifacts as well as the sediments in a pit at Tel Dor, on Israel's Carmel coast, dating to the 7th c. BCE – a period when the site served as an Assyrian administrative center. This pit was unusually large, had a peculiar ceramic assemblage, and many macroscopic metallurgical wastes. A detailed excavation and analysis revealed that the pit served intermittently as a waste disposal site for an iron smithy and for pottery that was presumably involved in maritime trading. On two occasions the area was also used for animal penning. Despite the obvious importance of the iron industry to the Neo-Assyrian Empire, actual workshops are rare in its archaeological record. Hence the new information regarding an Iron Age iron smithy in the southern Levant contributes to the study of this industry, and also to the history of Dor in this period.  相似文献

Employment and training programs aimed at women and men without 4‐year college degrees address the needs of the majority of the working population. Noncollege women tend to hold lower‐paying jobs with fewer opportunities for advancement, compared with the opportunities noncollege men have. One type of policy seeks to increase the numbers of women in occupations where men hold most of the positions, or “nontraditional occupations for women” (NTOs). Since many NTOs require a college education, do such policies improve noncollege women's economic self‐efficacy? Is there a link between holding a nontraditional occupation and earning significantly higher wages? This study establishes that, indeed, these programs provide access to jobs that are linked to higher earnings. Such policies redistribute earnings opportunities to noncollege women successfully, and therefore improve the economic efficacy of noncollege women.  相似文献

The aim of this paper is to investigate the longevity and diversity of the Amazonian rainforest and to assess its likely future. Palaeoclimate and palaeoecological records suggest that the Amazon rainforest originated in the late Cretaceous and has been a permanent feature of South America for at least the last 55 million years. The Amazon rainforest has survived the high temperatures of the Early Eocene climate optimum, the gradual Cenozoic cooling, and the drier and lower carbon dioxide levels of the Quaternary glacial periods. Two new theories for the great diversity of the Amazon rainforest are discussed – the canopy density hypothesis and the precessional-forced seasonality hypothesis. We suggest the Amazon rainforest should not be viewed as a geologically ephemeral feature of South America, but rather as a constant feature of the global Cenozoic biosphere. The forest is now, however, entering a set of climatic conditions with no past analogue. The predicted future hotter and more arid tropical climates may have a disastrous effect on the Amazon rainforest.  相似文献

Throughout his medical career, Robert Dunn (1799–1877) published a number of clinical cases with postmortem reports involving acquired language disorders, with the first noted in 1842. He developed a physiologically informed approach to psychological function during the 1850s along with a group of notable colleagues Benjamin Collins Brodie, Henry Holland, Thomas Laycock, John Daniel Morell, and Daniel Noble. He was also active in ethnographic research on human origins and racial diversity. As such, Dunn represents an interesting player in the developing fields of neurology, psychology, and anthropology in England in the latter part of the nineteenth century. These various strands converged at the meeting of the British Association of the Advancement of Science in 1868, where Dunn shared the program of lectures on the cutting-edge topic of aphasia with Paul Broca (1824–1880) and John Hughlings Jackson (1835–1911). Dunn’s ideas developed over a longer time frame than his younger colleagues and as such represent a unique blending of concepts from the earlier work of Franz Josef Gall (1758–1828) and Jean-Baptiste Bouillaud (1798–1881) to the perspectives on language organization in the brain developed after 1861.  相似文献

In 1877, Barlow described a ten-year-old boy with right hemiplegia and aphasia, quick recovery of language function, and subsequent left hemiplegia and aphasia, who was shown to have symmetrical left and right Broca's area lesions at autopsy. The report of this case motivated many writers in the second half of the nineteenth century to develop theories on localization, laterality, equipotentiality and development of specialization, recovery of function, and the role of the right hemisphere (see Finger et al., 2003, for review). This paper presents an analysis of the original archived case notes that have recently come to light. Examination reveals discrepancies in significant details of the history of the case and raises questions about the degree of impairment and recovery throughout his illness as reported in the published article. Consideration of these differences between the presentation of the case in the British Medical Journal publication and the documentation in the original patient records raises issues about the validity of this case as evidence for the many arguments it was to support that have persisted to the present.  相似文献

This paper engages selected moments in Austin Clarke’s literary journey to argue that in spite of his involvement in the development of Canadian literature (CanLit) during the 1960s and 1970s, the Canadian literary establishment continues to pay little critical attention to his contributions. This lack of recognition is specifically evident in recent writings about Canadian literature and the literary figures who spearheaded its development after Canada’s Multiculturalism policy of 1971. Canada’s becoming officially multicultural required a new narrative of Canada and new literary depictions of Canadians in their national literature, as ethnically diversified but of a single citizenship. I argue that Clarke’s legacy as a Black writer should be given more prominence in Canadian institutions because today this legacy is under threat of erasure as the number of Canadian Black voices telling mainstream stories about Black people’s experiences is evidently in decline.  相似文献

The collapse of complex societies is a recurring theme in archaeological and historical scholarship. Zooarchaeological investigation, conventionally applied in recent studies to detect environmental degradation resulting in resource stress, is employed here to study the social conditions leading to the decline of the powerful Bronze Age city of Hazor, located in the northern Jordan Valley, Israel. The results of the analysis of faunal remains from the lower city show that the exclusion of its residents from ideological use of animals and their impoverishment by elite livestock expropriation preceded other material manifestations of sociopolitical decline in the city. The results are encouraging in respect to the prospective value of zooarchaeology for investigating collapse not directly caused by subsistence failures.  相似文献
