The paper offers a geographical interpretation of the evolving technical, political, and economic intricacy of large dams. It incorporates existing hydropolitical scholarship and the notion of the Chinese Water Machine to reframe dams as assemblages built by specific political, financial and technical processes in particular socioenvironmental regions. The paper examines the continuity of hydropolitical relationships through a genealogical inquiry into the formulation and materialisation of Ghana's three dams: the Akosombo and Kpong dams built during the Cold War, backed by Western lenders and engineering companies; and the Bui dam commissioned in the 2010s, with support from China. Based on fieldwork in Ghana and China, as well as documentary evidence, the paper argues that the thinking, planning and building of dams interconnect the host regime and external techno-financial actors with their floating political-economic interests, but in a durable way. Sometimes, even if little concrete is actually poured, the symbolic power of dams endures, transforms, and at certain times and places expands, through events and discourses of national and international interest groups pursuing their own purposes, albeit with the replacement of influential individuals and powerful institutions, and regardless of the involvement of Western, Chinese and/or other actors. Ruptures exist but do not necessarily break the continuity of dam assemblages. The emergence of an opposition assemblage that battles against dams is a more recent complexity.  相似文献

This paper reports the results of a pilot study that evaluated a prototype instructional module designed to support international collaborative learning in the World Wide Web. The module, Migration, was tested at four higher education institu tions in the United States, Canada, and Australia. Students valued the opportunity to learn global geography by collaborating electronically in multinational teams, yet many students complained about confusing instructional procedures and uncooperative team members. The results of the module evaluation provide useful suggestions for managing pedagogical issues related to the process of online international collaborative learning.  相似文献

This paper explores the career of Ruth Taylor White, an American cartographic illustrator who published a significant number of pictorial maps from the 1920s into the 1940s. Taylor White’s ‘cartographs’ (as she called them) were characterized by her signature bobble-headed cartoon characters who romped through colourful, attractive landscapes. These visually rich and highly narrative maps simultaneously strove for accuracy and engaged in profound stereotyping with regard to culture, race, gender and class. They reveal not only the aesthetic and conceptual preferences of their maker but also the cultural biases of their middle-class, white American audience.  相似文献

Mass violence always takes place in a particular geopolitical context, and how that context is understood influences perceptions of collective responsibility. As international borders shift, often in the wake of war, events that occurred within one geopolitical entity can be understood has having taken place in another. The influence of such geopolitical framing on judgments of collective responsibility remains understudied. Two studies examine how geopolitical frames lead to shifting assessments of collective responsibility for historical mass violence. By depicting historical violence within a particular geopolitical entity (e.g., a country), that entity was perceived as being more responsible for the violence. The studies are set within the contexts of German-occupied Poland and the British occupation of the Indian subcontinent. The ramifications of these findings are discussed for the teaching of history, the commemoration of historical victimhood, and for our understanding of assessments of collective responsibility and geopolitical framing more broadly.  相似文献

This paper seeks to understand the conditions of possibility of “sanctuary” – the claiming of a “sacred” space of (humanitarian) exception - in the midst of civil war. Sanctuary codifies an exceptional space where sovereign and pastoral registers of power converge into a form of “pastoral sovereignty” that can temporarily “interrupt” the law of violence of sovereign power. In civil war this can enable civilians to be saved and protected from killings and suffering. However, this pastoral sovereignty is precarious as it depends on the belligerents' good will and tacit authorization: this is what we call the predicament of pastoral sovereignty. Using the case study of Church sanctuary in Sri Lanka's civil war, this paper explores how this predicament of pastoral sovereignty comes into effect in moments of acute crisis. Throughout Sri Lanka's brutal civil war, Catholic priests provided “sanctuary” to Tamil civilians in the form of territorial sanctuary (Church compounds), bodily sanctuary (the priests' bodies providing protection), and numerous other humanitarian activities. Our ethnographic material illustrates the force and fragility of the Church's claims to pastoral sovereignty and its sanctuary practices and provides detailed accounts of numerous constellations. The paper thereby raises fundamental questions about the ontology of sovereignty and its operability in moments of humanitarian crisis.  相似文献

Significant advances in our understanding of ancient agricultural practices in the Americas have been made in recent years. This review of the literature focuses on studies published between 1987 and early 1994. Issues pertaining to the transition from foraging to farming include the habitability of the American tropics prior to the development of agriculture, theories on plant domestication and the origins of agriculture, regional syntheses of agricultural development, and the origin, evolution, and dissemination of domesticates in the Americas. Other topics reviewed include new techniques that have recently been applied to the study of prehistoric agriculture in the Americas, various approaches to the study of agricultural change, and ways in which research on ancient agricultural practices is being applied in modern experimental agriculture and rural development projects.  相似文献

In October 1942, five British civilians and 17 New Zealand coast-watchers were executed by Japanese military forces, at Tarawa, Gilbert Islands (Kiribati), in the central Pacific. The bodies were buried in a mass grave, the location of which became obscured when the Japanese constructed military fortifications. A battle was fought at Tarawa in November 1943 whereby the US Marines defeated the Japanese defenders and took control of the island. In the battle more than six thousand men died and their bodies were buried in hastily prepared and often unmarked graves. Since the end of the war the remains of hundreds of Americans and some Japanese have been located and recovered from Tarawa but nothing among the remains has been identified as belonging to the 22 British subjects. A problem in locating the grave of the British has been a lack of any record of its position. In this paper the authors consider the documentary evidence including an important map and a report on the first attempt, using local knowledge, to locate the grave. The specific area of the grave is identified, the date of the executions is confirmed and the reasons behind the order to execute are discussed.  相似文献

The investigation of a simple behavior, child naming, can provide insights into the varying reactions of families confronted by the extraordinary war losses of the First World War. The current study analyses names given in a large cohort of French orphans born 1914–1916, constructed thanks to the linkage of civil registers with a nationwide database of soldiers who died during the War. It shows that a prenatal loss of father was associated with a strong increase in father's name transmission. The phenomenon was twice as intense in officers' offspring. Regression analysis suggests the precise timing of the father's death controlled this change in naming behavior: father's name transmission was at a maximum when the father died at the very beginning of pregnancy.  相似文献
