Archaeological and chemical evidence for the earliest American use of raw coal as a fuel in ironmaking

The archaeological discovery of bituminous coal in the tipple area and the subsequent analyses of specimens of the iron ore, charcoal, limestone, slag, and cast iron from the Eaton (Hopewell) blast furnace built in 1802 indicate that raw coal was used in combination with charcoal as a fuel in American iron smelting at least thirty years before it was used alone. Further, its use in this combinatory manner marks the earliest as yet attested to in the New World.     

Forced migration and legal-spatial violence in the United States and Germany

Asylum laws cannot function without spatial technologies and practices. Refugee camps, detention centers and accommodation facilities, in addition to dispersal and residential obligations, highlight the spatiality of asylum laws and policies. They are not only designed to regulate forced migrants' movement and place them in alternative legal and spatial regimes, but they are also spaces where migrants’ legal rights are violated and access to integrating institutions are restricted. Based on findings from Germany and the United States, this paper argues that current asylum regimes are characterized by a system of legal-spatial violence; a process in which a form of violence is embedded in law, implemented through policies and formal processes, and realized and reproduced spatially. This entanglement between the law, space, and violence involves complex and paradoxical processes: immobility and internal bordering practices (where forced migrants are confined and their movement is limited), as well as forced mobility and situations of unbordering (where movement is forced, and where spatial restrictions are either repealed or replaced). These processes fragment and prolong the trajectories of forced migration. Compulsion, displacement, and the dispossession of rights—which constitute the process of forced migration—do not cease on entering Germany or the United States, but can continue. The rationale for legal-spatial violence goes beyond the securitization of forced migration and the control and deterrence of forced migrants, and also includes economic logic and profit making.     

Anarchists and national identity: The case of German radicals in the United States and Brazil, 1880–1945

How German were German anarchists in the United States and Brazil? Did the experience of exile and immigration preserve or even heighten a national identity among radicals who openly espoused revolutionary internationalism? Anarchists distinguished between nation and nationality on the one hand, and the state and nationalism on the other. This article examines expressions of nationality by a handful of German anarchist editors and writers from the 1880s to the end of World War II. They wanted to be stateless, but not nationless. This article argues that German exile anarchists in the United States and Brazil expressed a militant, countercultural, antistatist and anticlerical nationality. They were ‘rooted cosmopolitans’: They identified with the international revolutionary tradition and at the same time remained attached to Germany's heritage of radical politics, arts and humanities. There was a remarkable consistency in their commentary levelled against Bismarck, the Kaiser, the Weimar government and the Nazis either in Germany or in the host country. Anarchists advocated for a borderless global federation of free communities and, to that end, rejected nationalism and urged people to stop ‘seeing like a state’ by exposing the false promises and crimes of statism.     

建国初期美国阻挠华侨学生回国升学内幕

新中国成立后,海外华侨学生有感于祖国的繁荣昌盛,掀起了一股回国升学的热潮。国民党集团为了“反共复国”,也极力劝诱侨生赴台升学,但收效甚微。在此背景下,美国出于“遏制中国”的险恶用心,积极介入华侨学生的升学问题,并使之染上一层浓厚的冷战色彩。本文主要依据上世纪90年代公布的美国政府的有关原始档案,分析美国政府阻挠华侨学生回国升学的背景和动机及其制定的计划、采取的措施。作者认为,虽然美国政府所采取的阻挠华侨学生回国升学的政策和措施对华侨学生的流向产生了一定影响,但其“遏制中国”的野心并未得逞。

Defiance to compliance: Visions of the computer in postwar Britain

In a climate of profound uncertainty over Britain’s postwar status, some industrialists and policymakers sought solace in a ‘defiant modernist’ aesthetic, proposing radical technological transformations to circumvent economic constraints. The British computer industry, which briefly challenged that of the USA for technological sophistication, presents a revealing instance of this approach and its limitations. Early promoters, notably Vivian Bowden of Ferranti, shrewdly laid the rhetorical groundwork to position the new machines as the natural outcome of a uniquely British technological trajectory. Into the 1960s, however, their agenda was disrupted not only by economic realities, but also by the increasing importance of software and compatible systems as opposed to individual machines, and by growing public and industrial familiarity with computing in general. Promoters sought new points of differentiation, but had made little headway when a combination of national policy changes, growing market dominance by US-based corporations, and Anglo-French rapprochement rendered the British national exception largely unworkable. Its powerful rhetorical appeal, however, ensured that it never entirely disappeared.     

Hurricane impacts on southeastern United States coastal national park visitation

As a major contributor to local economies, the tourism industry has been greatly impacted by natural disasters. This study demonstrates the association between tourism economies and impacts of hurricanes in the southeastern United States containing coastal national parks, known for attracting a large number of tourists and having experienced hurricanes. In keeping with two longitudinal data methods (i.e. panel logit model and autoregressive integrated moving average), this study focused on the relationship between the (1) duration, intensity, and damage of hurricanes; (2) existing climate conditions; and (3) tourism demand on park visitation during hurricane and tourism seasons. As a whole, the impacts of hurricanes and climate conditions (precipitation, temperature) were found to have a negative effect on tourism demands (park visitation). With regard to the response of tourism economies to natural disaster damage, parks that experienced stronger natural disasters may be closed for a longer period in order to reconstruct facilities or natural/cultural resources damaged by storms. In an attempt to improve tourism-based regional economies, overcome the challenge of natural disasters on tourism economies, and increase opportunities for establishing disaster management, it is necessary to make an effort to allay unexpected damage to tourism-based areas through proactive plans for disaster mitigation activities.
