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 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

Qatar, a small Gulf Arab nation with a de facto absolute monarchy, held its first general elections ever for 30 Shura Council seats on October 2, 2021. This marked the first time in Qatar's history that citizens played a more direct role in government, moving beyond symbolic elections. This study aimed to examine the factors likely to have influenced voters' selection of candidates, the key issues that are significant to Qatari citizens, and the possible characteristics of candidates that are deemed essential. While informal conversations are the main method of data collection for this study, social identity theory, specifically group-based models, was used to understand the influences that shape Qatari voters' choices of candidates. Findings indicate that tribe-related and family-connected attributes constitute important influences on voters' choice decisions. Moreover, voters were concerned about candidates' characteristics and the issues and policies candidates deemed important. Discussion and recommendations are provided.  相似文献

This article focuses on Finnish national identities because they expressed the shared experiences of newly established Finnish communities, and they were crucial in constructing a new nation. It also explores created images of the Finnish and Finland, as well as community construction in Republican China, especially after Finland gained independence in 1917. Another aim is to examine those Finnish political, cultural and economic activities that supported their identity construction in China. The specific emphasis will be on analysing the largest and sometimes cross-functioning Finnish groups in China: the governmental officials and the commercial community. By using qualitative methods, namely, discourse analysis and historical analysis, this study shows how the Finnish community created alternative, sometimes imaginative and frequently anti-imperialist national identities in the new Republican China. Indeed, by signing the Treaty Principles of Reciprocity and Equal Treatment, it was agreed that Finland and China ‘shall enjoy same rights, privileges, favours, immunities and exemptions which [might] be accorded to similar foreign agents in accordance with the principles of international law’. This article argues that Finnish aspirations were positively regarded by many Chinese, and they respected this quite unique national connection with Finland.  相似文献

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce .  相似文献

Between 2012 and 2019, Manus Island, Papua New Guinea, hosted Australia's offshore detention centre for asylum seekers and refugees, known as the Regional Processing Centre (RPC). This paper analyses some of the social impacts of the RPC on Lorengau town, the urban centre of Manus, through the analytical lens of the Manus idiom, as basket (Tok Pisin). Materially this refers to the everyday Manus basket whilst metaphorically, it refers to an individual's or community's social, cultural, political and economic base. First, I examine asylum seekers and refugees as a social category that emerged during this period when they were referred to as papu by locals. Papu is an honorific kinship term for grandfather or elder man; for men who are symbols for family identity, social belonging, and rights to land. Second, I examine the changing materiality of Lorengau's markets as indicative of wider societal transformations and dissonance brought about by the RPC. My ethnographic data are based on long term involvement in Manus, including three recent visits to Lorengau in 2017, 2018, and 2019 where I studied the social impacts and the changing social practices of Manus people in response to the RPC.  相似文献

This paper contributes to a critical methodological discussion that has direct ramifications for policy studies: how computational methods can be concretely incorporated into existing processes of textual analysis and interpretation without compromising scientific integrity. We focus on the computational method of topic modeling and investigate how it interacts with two larger families of qualitative methods: content and classification methods characterized by interest in words as communication units and discourse and representation methods characterized by interest in the meaning of communicative acts. Based on analysis of recent academic publications that have used topic modeling for textual analysis, our findings show that different mixed‐method research designs are appropriate when combining topic modeling with the two groups of methods. Our main concluding argument is that topic modeling enables scholars to apply policy theories and concepts to much larger sets of data. That said, the use of computational methods requires genuine understanding of these techniques to obtain substantially meaningful results. We encourage policy scholars to reflect carefully on methodological issues, and offer a simple heuristic to help identify and address critical points when designing a study using topic modeling.  相似文献

As science becomes an increasingly crucial resource for addressing complex challenges in society, extensive demands are placed upon the researchers who produce it. Creating valuable expert knowledge that intervenes in policy or practice requires knowledge brokers to facilitate interactions at the boundary between research and policy. Yet, existing research lacks a compelling account of the ways in which brokerage is performed to gain credibility. Drawing on mixed‐method analysis of 12 policy research settings, I outline a novel set of strategies for attaining symbolic power, whereby policy experts position themselves and others via conceptual distances drawn between the “world of ideas” and the “world of policy and practice.” Disciplinary distance works to situate research as either disciplinary or undisciplinary, epistemic distance creates a boundary between complex specialist research and direct digestible outputs, temporal distance represents the separation of slow rigorous research and agile responsive analysis, and economic distance situates research as either pure and intrinsic or marketable and fundable. I develop a theoretical account that unpacks the boundaries between research communities and shows how these boundaries permit policy research actors to achieve various strategic aims.  相似文献

Island peoples around the world remain entangled in colonial processes. Western and metropolitan powers are increasingly deploying discourse of a ‘China threat’ to justify neocolonial entrenchment in the form of greater Western militarisation and economic dominance. In this paper, we investigate how Western and metropolitan powers use the China threat and warnings of economic, environmental, demographic, and military disaster to maintain and deepen colonial influence in former colonies, with special focus on four island states and territories: Guåhan/Guam in Oceania, Kalaallit Nunaat/Greenland in the Arctic, Okinawa in East Asia, and Jamaica in the Caribbean. We undertake this investigation as a means of practicing decolonial political geography, collaborating as a group of scholars from around the world and drawing upon diverse epistemologies and experiences to inform collaborative research and writing. Due to the complexities we have confronted in our efforts to think outside coloniality, this paper foregrounds our decolonial methodology and process, even as we respect our empirical findings.  相似文献

Cattle slaughter and beef consumption are barely mentioned in the literature on Chinese economic, food, or animal history. This is possibly due to the widely held popular and scholarly assumption that beef was avoided and even considered taboo in the daily diet of Chinese people in premodern times. This article investigates the tangible regulation and practice of cattle slaughter in Qing China—the period when the beef taboo was argued to be formally subsumed into Chinese morality. I ask the following questions: To what extent did the Qing state ban cattle slaughter? How was the ban enforced in the localities? Did Chinese people slaughter cattle for consumption? Were there lawful beef markets in Qing China proper? How did increasing beef-eating Western sojourners since the mid-19th century impact this sector? Accordingly, I demonstrate that with the leeway provided by the state, the cattle slaughter industry developed in many regions of China proper, especially large cities. In this sector, Chinese Muslim merchants played a dominant role, even though the Han merchants could outnumber them. Their efforts have prepared the state and Chinese merchants to better cope with new circumstances since the mid-19th century. Broadly, this paper sheds light on how different religious, ethnic, and national groups affected the economy and the practice of law in the Qing dynasty.  相似文献
