Between 1876 and 1881 Massachusetts experienced an outbreak of human rabies (hydrophobia). The entire state--the Governor, the legislature, the State Board of Health, newspapers, and the citizenry and elected officials of every town and city--reacted to the disease. Central to the response was the Commonwealth's legislature--called the General Court. Through public hearings, their own debates, and the passage of legislation, it resolved widespread fear and anger, mediated conflicting concepts of disease, and promoted social solidarity in the face of an epidemic. This article first narrates the General Court's legislative actions; it then examines the conflicting understandings of disease causality; finally, it explores the social and political rituals the legislature drew upon to deal with this public health crisis. Arguing that public health legislation is simultaneously instrumental and symbolic, this article demonstrates that attention to both enriches the study of epidemics, historical and yet to come. 相似文献

1917年墨西哥政府颁布了一部限制外国人在墨拥有财产的新宪法。此后不久德国外交部长阿瑟·齐默曼发电报给墨西哥领导人卡兰萨,提议双方建立同盟关系。为了更有效地控制全国,不久卡兰萨宣布没收英国在墨西哥的最大投资——铁路。这一系列举动严重激化了墨西哥与美国和英国的矛盾。1917-1918年,美英之间就如何处理与卡兰萨政府的关系问题产生了巨大分歧,但由于需要美国的帮助,英国政府最终作出了妥协。第一次世界大战的结束使英国失去了在墨西哥的影响力,从而进一步加强了美国对拉美地区的控制。 相似文献

有关中国在联合国的代表权问题,美国的基本立场是反对中国代表权变更,尽管在朝鲜战争爆发前后有微妙的区别,此前主要是私下操纵,此后则公开阻挠。英国的投票立场经历了从弃权、赞成中国代表权变更到最终支持美国在联合国搁置对中国代表权问题讨论的演变过程。而且,英国赞成新中国取得合法代表权并不意味着取缔国民党集团的非法代表,其政策转轨亦不同步。在1950年1-6月,英国开始由弃权走向有条件赞成新中国取得席位,美英分歧凸现,各自为自己的立场游说其他安理会成员国。1950年6月-1951年1月是美英分歧与协调的高峰时期,英国逐渐走向赞成接纳新中国代表同时驱逐国民党非法代表的立场。美国则不遗余力地反对中国代表权的变更。1951年2-6月,英国由赞成中国代表权变更转向支持美国在联合国搁置对这一问题的讨论,美英纷争基本平息。美英在这一问题上的分歧除了反映两国对华政策的差异外,也折射出两国对联合国组织的不同理念。 相似文献

With scant material interests at stake, and protection exacting a toll on military resources, Britain wanted out of Belize, its sole dependency in Central America. This desire became more pronounced by the 1970s as successive British governments sought to eliminate residual out-of-Europe political and military commitments. Exiting Belize, however, proved a three-decade challenge for Britain. Exploiting recently declassified British government documents, this article explains why leaving proved so intractable. The article explains how Guatemala’s territorial claim—and its threat to realise this claim by means of force—proved the main obstacle to Britain’s military exit. Repeated attempts in the 1970s towards a negotiated settlement with Guatemala failed. Instead the decade was marked by moments of acute tension. Unable to discount the possibility of a Guatemalan attack, Britain felt compelled to reinforce its military presence in the country at a time when it was trying to exit. Moreover, Britain had to offer continued protection as a necessary condition for Belize to proceed to independence in 1981. This post-independence defence guarantee was intended as a short-term measure, and Britain remained committed to ending its Belize commitment at the earliest opportunity. Yet British protection ended only in 1994. This article unpacks the political and military factors that best account for this protracted withdrawal. 相似文献

This article explores the nature, tactics and effectiveness of the vocal anti-Vietnam war movement in Britain. It focuses on the rhetoric and actions of a range of different groups, from the far-Left Vietnam Solidarity Campaign, to the broad-Left British Council for Peace in Vietnam and the labour movement. It asks how far the anti-war opposition was able to shape both government policy and public debate on the war, and positions the British opposition within its wider global anti-war context. It explores the meanings of solidarity (with the American, or global, anti-war movement or with the North Vietnamese) for the British movement, and it highlights the ultimately domestic focus of the campaign. 相似文献

The evolution of metallurgical practices over several millennia has resulted in human exposures to a diverse variety of toxic elements. These exposures were not just confined to the metalworkers, but in many cases broadly impacted the larger community and society. The role of lead in Roman civilization is particularly fascinating, where the available evidence of lead use in a myriad of applications by Roman civilization suggests the potential for elevated exposures. The present paper addresses the hypothesis that because of these practices, Roman occupants of ancient Londinium (43–410 ad ) were exposed to levels of lead that far exceeded exposures in the preceding populations of Iron Age Britain (700 bc –43 ad ). The elemental content and stable lead and strontium isotopic signatures of 30 femora from three Londinium cemeteries and radiocarbon-dated representative burials were examined and the results then compared with 70 femora dating to the pre-Roman Iron Age from the well-known Iron Age hillfort of Danebury, Hampshire, and from three cemeteries in East Yorkshire. Extensive efforts were directed at the minimization of sediment and soil contamination, the assessment of contamination from burial artefacts and a careful review of the burial context of specimens. Data for lead and 20 additional trace and major elements were obtained by magnetic sector inductively coupled plasma mass spectrometry (ICPMS), after acid dissolution of pre-cleaned bone cores. Lead isotope ratios in the bone core digests (and burial soils) were measured by multi-collector ICPMS. It was found that concentrations of lead in the Roman/Londinium-era femora were > 70-fold greater than those from pre-Roman populations. This was confirmed by femoral data obtained from the analysis of a pre-Roman burial from the early first century bc found adjacent to the Southern Cemetery. Several major and trace element metrics for diagenesis demonstrate that levels of lead in the bone are robust indicators of human exposure during life. Lead isotope data for the Roman population are consistent with previously identified widespread lead pollution. The pre-Roman populations contain lead isotopic compositions consistent with highly localized, minor sources of lead. Together, these data provide unequivocal confirmation that the Romans in Londinium were exposed to elevated lead levels. Elevated blood lead levels would have resulted, negatively affecting their health and possibly contributing to declining birth rates. 相似文献

In this paper zooarchaeological evidence from Iron Age and Roman sites in South-East Britain is presented and the results are applied to the continuing debate over culture contact and change following the Roman invasion. Evidence from Heybridge in Essex indicates that there were two stages of livestock development. These may reflect the import of new breeding stock into Britain. Differences between the rate of livestock development at this rural site and the nearby urban centre of Colchester indicate differing mechanisms of animal supply between the two sites. The appearance of very large cattle in Late Roman contexts at Boreham in Essex suggests that improvement of animals continued throughout the Roman occupation and was not merely an initial response to new economic and administrative demands. The biometrical evidence from these three sites is compared with evidence from elsewhere in Europe and the development of livestock during the Roman Period is shown to be complex and varied. The impetus and ideology behind the changes in animal husbandry following the Roman invasion in Britain are explored. 相似文献

巨文岛事件是近代东北亚国际关系史上的一个热点问题。从地缘政治观察,该事件是以朝鲜为地理中心的区域政治参与势力在当时的东亚权力格局下进行的一场国际政治博弈;从全球政治观察,是英俄两国在全球争夺势力范围矛盾激化背景下,在东亚地区的区域历史反映。作为事件主角的英帝国,在事件过程中运用“以中国为轴”的外交策略周旋于区域势力的外交压力之中,最后“借力中国”,用巨文岛这枚政治棋子与俄国达成局外妥协,成功地实现了遏制俄国海军进驻朝鲜的东亚战略目标。而中国则审时度势,在险恶的局势中谨慎的开展外交活动,有力地利用了局势施压俄国,实现了维护其在朝鲜半岛宗主权的初衷。 相似文献

Gi with sealed middle stone age and later stone age occurrences is located in the Dobe Valley along the Botswana-Namibia border. The phases of middle stone age settlement were linked to a semiarid streamway during the early Upper Pleistocene. A major humid interval followed, when a large lake was ponded in the Dobe Valley. Later stone age settlement appeared after this lake disappeared and was replaced by a mosaic of pans (ephemeral lakes). Subsequently, another period of humid environment favoured another valley-wide lake during the late Upper Pleistocene. Later stone age settlement resumed when this second lake deteriorated into the modern pan terrains of the Dobe Valley. In total, the Gi beds record multiple environmental changes both more humid and more arid than present during the Upper Pleistocene and Holocene, as well as a variable array of adaptive opportunities for prehistoric settlement. 相似文献

Throughout 1894, Chicago's churches were as divided by class as the nation itself. During the Pullman strike and boycott, the city's leading Protestant and Catholic authorities hewed to an ideology of contract freedom that precluded support for the American Railway Union. Meanwhile, a handful of young Protestant ministers championed the strikers, echoing the criticisms of those working-class Protestants who had long decried the established churches’ ties to capital. This latter bloc expressed its frustration not merely with words but also through uprisings within local churches and even by founding a church of its own. In light of these findings, the author argues that a grassroots social Christianity preceded an elite Social Gospel; and furthermore, that the participation of working-class persons in the contests over the shape of modern Christianity demands a rethinking of the boundaries of both religious and working-class history. 相似文献

This is the first regional analysis of the impact of Romanisation on subadult dietary patterns and related health parameters in Britain. A sample of 200 subadults from late Iron Age (LIA) and Romano-British (RB) Dorset were examined for dental health and specific metabolic diseases, and a sub-sample of 29 individuals were selected for nitrogen and carbon isotope analysis. The results showed that dental health declined in the Romano-British period and the incidence of scurvy and rickets rose. Increased consumption of marine foods in the RB period is indicated by an increase in δ13C between the LIA and RB subadults. After early childhood, there was no age-dependent variation in dietary protein in the RB and LIA populations from Dorset. We propose that these changes related to the introduction of urban living, Romanised diets and population migration. 相似文献

This study investigates the relationship between diet and cultural change in late Iron Age and Romano-British populations from Dorset, England (1st century BC to the early 5th century AD). Dorset was the only region in Britain to exhibit continuity in inhumation burial rites through these periods and a wide array of environmental, archaeological and material culture evidence is available there. A sample of N = 77 human adult and N = 17 faunal rib samples were utilized for carbon and nitrogen stable isotope analysis to test the hypothesis that Romanization of the diet would result in greater dietary variation. 相似文献

This article focuses on the history of Irish migrants in Birmingham in an attempt to enhance historical understanding of race, ethnicity and ‘whiteness’ in post-war Britain. To do so, it will look at two Birmingham histories: the Young Christian Workers’ Association’s report on the Welfare of Irish migrants in 1951, and anti-Irish violence in the aftermath of the Birmingham Pub Bombings of 1974. It will consider the extent to which Irish immigrants were victims of racism, what this meant in terms of discrimination and identity, and, in particular, how Irish experiences corresponded to that of black and Asian migrants. 相似文献

Rich settlement and burial evidence from the Baikal/Angara region in Central Siberia provides one of the most promising opportunities in the global boreal forest for studying Holocene foragers. The Neolithic and Early Bronze Age prehistory of the region is known to western scholars only through a few English translations of the works of A. P. Okladnikov. Since the publication of Okladnikov's model, the region has witnessed large-scale archaeological fieldwork that has produced abundant quantities of new evidence. Moreover, the model has been partly invalidated by extensive radiocarbon dating. Research advances over the last couple of decades have augmented the area's previous reputation but have also revealed the need for new theoretical perspectives and modern analytical techniques. 相似文献

This paper seeks to advance the so-called rising powers debate of the past 15 years by interrogating its selective use of the past. Key to the debate are the impact of rising powers like China on the international order, and how to accommodate them. Historiography plays a crucial but unappreciated role in the debate, as scholars look to the past to make sense of the future. Especially in the United States, many compare the US now to Great Britain before 1940, the idea being that both faced the same difficulties of decline relative to rising challengers. This is the core case of power transition theory in the field of International Relations. It is also, fundamentally, weak. As I show, it relies on a ‘long chronology’ of British decline that the past quarter-century of historical scholarship on twentieth-century Britain has undermined. I instead propose a ‘short chronology’ of the transition away from Britain that emphasizes agency and contingency over structure and the longue durée. Bringing the work of historians to the rising powers debate thus indicates that the key factors to study are not grand systemic forces, but short-term politics and diplomacy. 相似文献

This paper examines the Little Ice Age in the Scottish Highlands and Islands and uses documentary evidence to show its impact on the farm economy. It has three sections. The first examines how Highland climate may have changed during the Little Ice Age, and notes that increased storminess was probably as much a factor as lower annual mean temperatures. The second takes the most severe phase of the Little Ice Age, the Maunder Minimum, 1645–1715, and uses rests or eases of rent to show how it stressed the farm economy. The third examines evidence for the abandonment of land during the Maunder Minimum. As well as arguing that we need to see abandonment in its social as well as physical setting, it highlights the role played by the temporary abandonment of land and suggests that such abandonment along the western seaboard probably indicates the impact of increased storminess. 相似文献
