Summary

The idea of interdisciplinarity can be articulated in different ways. The aim of the article is to criticise the view that interdisciplinarity is to be treated as a quality of the historian's approach to his subject-matter, and to argue for a constructivist interpretation of that notion. A constructivist account of interdisciplinarity relies on the thesis that the latter is one of the manifold ways in which it is possible to give sense to the historical records of which the historian wants to gain knowledge. In the paper it is maintained that the function of the notion of interdisciplinarity is to account for the clash of languages that can be found when disciplines converge. This new paradigm is highlighted by taking into consideration the history of American pragmatism.  相似文献

Under what conditions do rebel groups collaborate with the government in disaster relief operations? Despite the fact that many natural disasters occur in armed conflict contexts, little is known about the impact of conflict actors on natural disaster relief efforts. Affected by the same typhoon, the Moro Islamic Liberation Front (MILF) and the New People's Army (NPA) behaved differently in the aftermath of the natural disaster. While the MILF collaborated with the government in relief efforts, the NPA did not. This article explains this variation by arguing that the level of hostility between the rebel group and the state in the pre-disaster period as well as the type of social contract that exists between the rebels and the local population shape collaboration during natural disaster relief efforts. The theoretical argument is explored through a comparative case study between these two rebel groups in the aftermath of a devastating typhoon in the Philippines in 2012.  相似文献

In the introduction to his Spalt und Fuge, Hans-Jörg Rheinberger points to the possibility that we are currently experiencing a new turning point regarding forms of experimentation, which is characterized by the growing importance of high-throughput methods and big data analytics. This essay will explore the thesis that data-intensive research indeed constitutes a form of post-experimental research by interrogating research practices in precision medicine. Section 1 will introduce this thesis and highlight salient features of precision medicine as an example of post-experimental research. Section 2 suggests approach as a category that is broader than experimental system, as discussed by Rheinberger, and can serve to analyze and compare diverse forms of research, including experimental and post-experimental practices. The essay concludes with a reflection on how categories developed for the historiography of recent science might require an update when the science or its context changes (section 3).  相似文献

Oceans are increasingly looked toward for their contribution to addressing climate change. These so-called ocean-based climate “solutions” often fall under the umbrella of the “blue economy,” a term used to refer to new ways of organizing ocean economies to provide equitable economic and environmental benefits. Yet, thus far the literature exploring blue economies and blue economy governance has largely overlooked or downplayed its equity and justice roots and implications, including how blue economies are embedded in multiple scales of environmental injustices. This is particularly important when blue economies include offshore oil production. The purpose of this paper is to both emphasize the need and provide an approach to incorporate justice and equity—specifically climate justice—into blue economy planning and scholarship. We build on conceptualizations of blue economies as assemblages to draw attention to the global reach of climate impacts associated with oil that are often overlooked or ignored at sites of production and through regional governance. We argue that greenhouse gas emissions from the life cycle of oil should be included in policies and planning (including blue economy planning) at sites of production, but that this must also incorporate underlying power structures that lead to uneven impacts and climate injustice. We look at environmental assessments as a regional governance tool that could be used to shape opportunities and openings to organize blue economies differently. To illustrate these points, we look at how environmental assessments are playing (and could play) a role in enacting and shaping Newfoundland and Labrador's blue economy.  相似文献

This study presents the effect of active learning methods of concepts in geographical information systems where students participated in a series of interlocked learning experiences. These activities spanned several teaching weeks and involved the creation of a hand drawn map that was scanned and geo-referenced with locations' coordinates derived from virtual earth systems. These activities engaged students' attention, and the completion of the activities provided opportunities for formative feedback and summative assessments. The effect of the group of activities on students' learning was quantified through the collection of summative assessment data which was compared to performance in other assessment tasks.  相似文献

This paper critically reviews the use of video documentaries in the assessment of human geography field courses. It aims to contribute to recent debates about the role of visual methods for developing active and deep learning in student-centred teaching. Based on four days of group work in Crete, 30 third-year students produced individual 10-minute video documentaries on ‘Mediterranean Rural Spaces’. Analysing students' experiences of video production highlights the need for innovative teaching and assessment methods and the importance of creating independent and creative students equipped with a broad set of skills for an increasingly flexible job market.  相似文献

This paper reviews the opportunities and challenges for re-framing the purpose, process, product and assessment of final-year geography dissertations. It argues that the academic centralities of critical thinking, analysis, evaluation, effective communication and independence must be retained, but that the traditional format limits creativity and innovation. Re-imagining capstone projects has implications for students, faculty, departments and institutions, but greater diversity could enhance its relevance to students and employers, better aligning the student experience with the academic interests and future career demands of the 21st century graduate.  相似文献

有明一代的北京营建,曾征办了巨量的砖、瓦、琉璃等烧造物料,其规模之大,历代罕匹。在明代北京营建中,其前后烧造地域的空间变化、烧办方式变迁等诸问题非常值得探讨。明代中期以来社会经济的发展及纳银代役制度的变化,导致了烧办方式的变迁,而烧办方式的变迁,则直接影响到烧办地域范围的调整。  相似文献

Analyzing chronological patterns is one of the major issues in archaeology. How can the date of a specific context be estimated? Is it possible to identify residual and intrusive material in it at the same time? Numerous statistical methodological approaches have been developed and implemented to estimate dates but have less often addressed the issue of socio-economic area or the functional interpretation of contexts. This article deals with the construction and analysis of two different probability estimate density curves of context dates using pottery. By contrasting the two curves we can define the boundaries of the socio-economic area and make a chrono-functional interpretation of a context. This statistical tool allows the archaeologist to visualize and analyze chronological patterns easily. The method is applied to the analysis of contexts in the town of Tours in particular and more generally in the centre-west of France, based on collected pottery finds.  相似文献
