The Cold War

Until recently, East Asia was a boiling pot of massacre and blood-letting. Yet, almost unnoticed by the wider world, it has achieved relative peace over the past three decades.1 At the height of the Cold War, East Asia accounted for around 80 percent of the world’s mass atrocities. By the second decade of the twenty-first century, it accounted for less than 5 percent....

Abstract This article argues for a ‘history from between’ as the best lens through which to understand the construction of historical knowledge between East Asia and Europe. ‘Between’ refers to the space framed by East Asia and Europe, but also to the global circulations of ideas in that space, and to the subjective feeling of embeddedness in larger-than-local contexts that being in such a space makes possible. Our contention is that the outcomes of such entanglements are not merely reactive forms of knowledge, of the kind implied by older studies of translation and reception in global intellectual history. Instead they are themselves ‘co-productions’: they are the shared and mutually interactive inputs to enduring modes of uses of the past, across both East Asian and European traditions. Taking seriously the possibility that interpretations of the past were not transferred, but rather were co-produced between East Asia and Europe, we reconstruct the braided histories of historical narratives that continue to shape constructions of identity throughout Eurasia.

Abstract East Asia occupies a substantial position in IUPAC today. The incumbent president for 2018-2019, Qi-Feng Zhou, is from China/Beijing, and three out of ten elected members of the Bureau are from East Asia: Mei-Hung Chiu from China/Taipei, Kew-Ho Lee from Korea, and Ken Sakai from Japan. This region is thus well-represented in the IUPAC leadership. However, this is not how this now global institution looked in the past. Its first president from East Asia was Saburo Nagakura (b. 1920) from Japan who assumed this office from 1981-1982, more than 60 years after the IUPAC was established in 1919. He was followed by Jung-Il Jing from Korea (2008-2009), Kazuyuki Tatsumi (2012-2013) from Japan, and Zhou. In terms of national adhering organizations (NAOs), Japan was the first East Asian nation admitted to IUPAC in 1921, but we had to wait until the late 1970s for all other national chemical communities in East Asia to be officially admitted to the IUPAC: The Chemical Society Located in Taipei in 1959, the Korean Chemical Society in 1963, and the Chinese Chemical Society in 1979. East Asia’s position in the IUPAC is the outcome of a rather long historical process.

NEAT is a loosely constituted regional scheme under the ASEAN plus Three (APT) framework. Its main objectives are to promote exchange among APT scholars and research institutes in the region, and to promote relevant research that can facilitate the APT regional cooperation process. Research is done through organising Working Groups. NEAT has made important progress in the past 10 years. To grow and expand in future, it will have to improve on its networking function and strengthen its Working Group mechanism.

Abstract Observers of East Asia frequently claim that Japanese nationalism is on the rise, and that Tokyo is abandoning its longtime military restraint. To determine whether these trends are indeed occurring, we define and measure Japan's nationalism and military assertiveness; we measure whether they are rising relative to Japan in the past, and relative to seven other countries. Drawing from social identity theory, we distinguish between “nationalism” and a more benign “patriotism.” We find in Japan (1) strong patriotism that is stable over time, and no evidence of rising nationalism. Furthermore we find that (2) military assertiveness remains generally low, but it has risen in terms of decreased institutional constraints and peacekeeping activities. Our findings have important implications for academic debates about nationalism and Japanese security policy, and for policy debates about a nascent balancing effort against China.

Abstract International relations (IR) has seen a proliferation of recent research on both international hierarchies as such and on historical IR in (often hierarchical) East Asia. This article takes stock of insights from East Asian hierarchies for the study of international hierarchy as such. I argue for and defend an explanatory approach emphasizing repertoires or toolkits of hierarchical super- and subordination. Historical hierarchies surrounding China took multiple dynastic forms. I emphasize two dimensions of variation. First, hierarchy-building occurs in dialogue between cores and peripheries. Variation in these relationships proliferated multiple arrangements for hierarchical influence and rule. Second, Sinocentric hierarchies varied widely over time, in ways that suggest learning. Successive Chinese dynasties both emulated the successes and avoided the pitfalls of the past, adapting their ideologies and strategies for rule to varying circumstances by recombining past political repertoires to build new ones. Taken together, these phenomena suggest new lines of inquiry for research on hierarchies in IR.

The present study tends to describe the survey of climatic changes in the case of the Bojnourd region of North Khorasan, Iran. Climate change due to a fragile ecosystem in semi-arid and arid regions such as Iran is one of the most challenging climatological and hydrological problems. Dendrochronology, which uses tree rings to their exact year of formation to analyse temporal and spatial patterns of processes in the physical and cultural sciences, can be used to evaluate the effects of climate change. In this study, the effects of climate change were simulated using dendrochronology (tree rings) and an artificial neural network (ANN) for the period from 1800 to 2015. The present study was executed using the Quercus castaneifolia C.A. Meyer. Tree-ring width, temperature, and precipitation were the input parameters for the study, and climate change parameters were the outputs. After the training process, the model was verified. The verified network and tree rings were used to simulate climatic parameter changes during the past times. The results showed that the integration of dendroclimatology and an ANN renders a high degree of accuracy and efficiency in the simulation of climate change. The results showed that in the last two centuries, the climate of the study area changed from semiarid to arid, and its annual precipitation decreased significantly.

East Asian Climate

Unprecedented heatwave-drought concurrences in the past two decades have been reported over inner East Asia. Tree-ring–based reconstructions of heatwaves and soil moisture for the past 260 years reveal an abrupt shift to hotter and drier climate over this region. Enhanced land-atmosphere coupling, associated with persistent soil moisture deficit, appears to intensify surface warming and anticyclonic circulation anomalies, fueling heatwaves that exacerbate soil drying. Our analysis demonstrates that the magnitude of the warm and dry anomalies compounding in the recent two decades is unprecedented over the quarter of a millennium, and this trend clearly exceeds the natural variability range. The “hockey stick”–like change warns that the warming and drying concurrence is potentially irreversible beyond a tipping point in the East Asian climate system.
