Green cities? Urbanization,trade, and the environment

Is urbanization good for the environment? This paper establishes a simple core–periphery model with monocentric cities, which comprises key forces that shape the structure and interrelation of cities to study the impact of the urban evolution on the environment. We focus on global warming and the potential of unfettered market forces to economize on emissions. The model parameters are chosen to match the dichotomy between average “large” and “small” cities in the urban geography of the United States, and the sectoral greenhouse gas emissions recorded for the United States. Based on numerical analyzes we find that a forced switch to a system with equally sized cities reduces total emissions. Second, any city driver which pronounces the asymmetry between the core and the periphery drives up emissions in the total city system, too, and the endogenous adjustment of the urban system accounts for the bulk of the change in emissions. Third, none of the city drivers gives rise to an urban environmental Kuznets curve according to our numerical simulations. Finally, the welfare‐maximizing allocation tends to involve dispersion of cities and the more so the higher is the marginal damage from pollution.     

Yoshikatsu Sugiura's Contribution to the Development of Quantum Physics in Japan

Previous research in the history of physics has led us to believe that Yoshio Nishina (1890–1951) virtually single‐handedly imported quantum physics into Japan. However, there are first‐hand accounts that Yoshikatsu Sugiura (1895–1960) also played an important role. Sugiura made his name in quantum chemistry with his contribution to the Heitler‐London theory of the chemical bond. Yet, historians of physics have paid scant attention to him. This paper brings forward information on Sugiura from his letters, his scientific papers, and his own recollections until ca. 1930. By examining this material, the present paper studies Sugiura's accomplishments in Europe and his contributions to the development of quantum physics in Japan. We conclude that Sugiura was one of the most important physicists when it comes to the arrival of quantum physics in Japan. In addition, we assess why he has been under‐appreciated in the history of physics in Japan. Our historical study on Sugiura suggests that, in addition to the position Nishina and his students rightfully occupy, there still are important unexplored aspects in the history of Japanese quantum physics.     

Co-chairing Asia-Pacific defence diplomacy: the case ASEAN Defence Ministers’ Meeting Plus

This article assesses co-chairs’ roles in affecting the outcomes of Asia-Pacific defence diplomacy, which have been under-examined. Attempting to mend this intellectual gap, our study examines: ‘What shapes specific agreement details?’ We contend that co-chairs’ effectiveness is not borne out of resource possession but in fact derived from their ability to manage the resources. In order to be effective, co-chairpersons must convert the available resources at hands into bargaining leverage. To validate our argument, empirical analysis of military medicine (MM) collaboration under the ASEAN Defence Ministers’ Meeting Plus (ADMM-Plus) framework was conducted. We demonstrate how the Thai and Russian co-chairs altered the bargaining dynamics to shape the outcomes regarding the ASEAN Center of Military Medicine (ACMM). Insights from our analysis not only extends the existing academic literature on Asia-Pacific defence diplomacy and international negotiation, but also provides practitioners with lessons useful for conducting defence diplomacy and enhancing security cooperation in the Asia-Pacific and beyond.     

Wissenschaftsstädte – Zur Bedeutung des Topos der ‘kreativen Stadt’ für die Wissensproduktion

Science Cities: What the Concept of the Creative City Means for Knowledge Production. – The article aims to show that the relationship of science and the city has changed since the 1970s in the context of the knowledgeable society. While cities have principally been regarded as the typical space of science, of new ideas and innovation for centuries, since the 1960s and 1970s universities, research institutes as well as industrial research institutes have relocated to the periphery of cities. There, however, these sites of knowledge have been organized in an ‘urban mode’. That means that the concept of the city as a place of science and innovation has determined the architectural, spatial, and social organization of these sites on the periphery of cities. Certain features of the city have been copied, such as social infrastructures, places of communication, restaurants, cafes etc., while others have been left out – housing, cinema, theatre etc. An ‘urban mode of knowledge production’ in the sense of a very stylized model of the city has become a tool to enhance the production of scientific and technological knowledge. – The article exemplifies this by focusing on a case study, namely of the so‐called ‘Science City’ of the Siemens Company in Munich‐Neuperlach.     

尉氏元代壁画墓札记

尉氏县张氏镇壁画墓在最近的报道中被断为宋代。本文结合相关考古资料,从墓葬形制、壁画布局、仿木结构、人物服饰、墓门题记等几个方面进行对比分析,将该墓订正为元代。又依据文献记载和图像资料,对该墓壁画中“曾参行孝”和“焦花女哭麦”两组孝子图加以考证。并进一步梳理了考古所见二十四孝图像,发现其组合形式在宋金时期比较稳定,而元明时期则逐渐转向多元。     

清代帝陵的哑巴院和月牙城

本文论述清代帝陵中的哑巴院和月牙城的建置与功用,进而探讨其规制的起源问题。指出关外的福陵与昭陵系参照北京明代后期的帝陵及清孝陵兴建,而南京明孝陵的规制已见哑巴院的雏形,其发展演变脉络清晰,故而哑巴院和月牙城并非明清两代帝陵规制最显著的差别。     

DEMOGRAPHIC CHANGE AS A FUTURE CHALLENGE FOR CITIES IN EAST CENTRAL EUROPE

Contemporary cities in East Central Europe (ECE) represent a hybrid type of urban development which is still generally considered to be a special case and is only exceptionally referred to in the recently intensified debate over the European city. Our paper argues that such exclusion is short‐sighted because ECE cities face structural problems similar to those of their Western pendants. Therefore, the contextual frame of urban research needs to be widened and can no longer be restricted to post‐socialist transition. In this regard, one of the main challenges for future urban development will be the consequences of demographic change. Ageing, new patterns of fertility behaviour and more diversified household structures in line with the Second Demographic Transition (SDT) will have significant implications for urban structures and housing markets, as already known for Western Europe. The purpose of this paper is to work out new questions and hypotheses for future urban research with special respect to Polish and Czech cities. Besides West European experience, recent developments in eastern Germany are taken as a frame of reference, assuming that this specific transition case may, in many respects, be regarded as a forerunner for similar developments in its neighbouring countries.     

清初苏州商船赴日贸易史实辨析

顺治九年(1652),一艘赴日本贸易的苏州商船回国。史学界对该商船的赴日时间及贸易方式存在争议:一说是1644年赴日,在日本进行了八年的海外贸易;一说是1650年或1651年私自出海,交易完毕后即回国。本文根据明清档案及朝鲜史料对该事件的记载,以及当时中国、东南亚、日本之间的贸易状况进行综合考察,可以肯定该商船是于1644年前往日本,并在日本与交趾之间从事贸易活动。     

Transitions in cast iron technology of the nomads in Mongolia

Metallurgical study of seven cast iron artifacts recovered from sites of the former Xiongnu (BC 3rd to AD 1st), Turk (AD 6th to 8th), Khitan (AD 10th to 12th), and Mongolian empires (AD 12th to 15th) shows that the earlier Xiongnu and Turk artifacts were made of cast iron alloys of near eutectic composition. The later Khitan and Mongol objects had greatly reduced carbon content in the range of ultrahigh carbon steel rather than cast iron, and contained more than 0.5 mass % silicon as an alloying element. Inclusions high in sulfur, phosphorus or silicon are also present. These differences suggest that Mongolia experienced a technical transition a few centuries before the establishment of the Mongolian empire, which is in agreement with some written accounts. The microstructures of the cast iron artifacts are compared with the related archaeological and documentary evidence. The results suggest that the use of fossil coal in smelting and the state policy of controlling iron production were the major factors responsible for the transition.
