清季俄罗斯文馆延聘俄人教习研究

在俄罗斯文馆存在的一个半世纪里,先后有多名俄人担任教习之职。康熙年间,文馆教习由俄国商队成员、降人及后裔充任,教习队伍不稳定,语言水平也不高。从雍正初期起,文馆开始延聘俄国东正教驻北京传教士团成员担任教习,其中罗索欣、弗拉德金和列昂季耶夫与满人富勒赫合作编写出中国第一本俄语教科书。自道光年间起,有4位传教士团领班被俄罗斯文馆聘为教习,但由于鸦片战争爆发后中俄关系的实质已经由以往的平等交往转向了俄国伙同西方列强对中国进行瓜分,他们并未发挥出"协同教授"的作用,更多时候是将在文馆兼职作为为俄国政府探听清廷内情的机会或手段。     

Putin,national self-determination and political independence in the twenty-first century

This contribution focuses on the right of nations to self-determination after the Russian invasion of Ukraine. It suggests that sovereignty and territorial integrity are not as secure as once thought. A number of articles and statements issued by Vladimir Putin are analysed to identify nationalist themes which he uses to reject Ukraine's right to exist outside the Russian state. Key themes include a primordial account of national origins, the conflation of state and nation, and a refusal to recognise a right to self-determination of territories that had once been part of Russia. Putin's nationalism draws on imperial nationalism, state nationalism, revanchism and majoritarianism to underwrite his claims. Such views are widespread among established states, contributing to the instability of the contemporary world. It is argued that a reconfiguration of the relationship between state and nation is long overdue, as is the inflexible nature of territorial integrity.     

Substitute or addition to hypermobile lifestyles? Second home mobility and Finnish CO2 emissions

Tourism produces an increasing share in global greenhouse gas (GHG) emissions. These are mostly derived from transport emissions, and long-haul air travel in particular. Short-haul domestic tourism is believed by some to be a potential substitute for long-haul tourism. Using the example of Finland this paper examines the extent to which domestic second home tourism can substitute for other leisure trips and therefore contribute to reductions of travel-generated GHG emissions. Survey data are used to evaluate the CO₂ emissions caused by travel to domestic second homes, and to create statistical models that verify if the owners of domestic second homes travel to other leisure destinations less frequently than others, and if they cause less emissions by their leisure mobility than others with comparable economic and demographic background. We find that although the owners and users of domestic second homes travel for other leisure purposes less frequently than others, this does not mean their leisure mobility generates less emissions. Overall, owners of second homes produce significantly more CO₂ by their leisure mobility than non-owners. The use of second homes does not seem to be a substitute for high emission long-haul travels, but rather a part of an overall highly mobile leisure lifestyle. It is therefore necessary to better understand and influence the entire range of individual mobility behaviours in order to reduce travel-related GHG emissions.     

Quantitative estimation of overpressure caused by gas generation and application to the Baiyun Depression in the Pearl River Mouth Basin,South China Sea

Hydrocarbon generation can yield high fluid pressures in sedimentary basins as the conversion of solid kerogen to hydrocarbons can result in an increase in fluid volume. To quantify the relationship between gas generation and overpressure in source rocks, a set of equations for computing the pressure change due to gas generation has been derived. Those equations can be used to quantitatively estimate overpressure generated by type III kerogen in source rocks by considering gas generation and leakage, gas dissolution in formation water and residual oil, thermal cracking of oil to gas, and hydrocarbon episodic expulsion from source rocks. The equations also take consideration of other factors including source rock porosity, transformation ratio, total organic carbon (TOC), hydrogen index, and compressibility of kerogen, oil, and water. As both oil and gas are taken into account in the equations, they can also be used to estimate the evolution of overpressure caused by hydrocarbon generation of type I and type II kerogen source rocks. Sensitivity analyses on the type III kerogen source rock indicate that hydrogen index is the most influential parameter for overpressure generation, while TOC and residual gas coefficient (β: ratio of residual gas over the total gas generated) have a moderate effect. Overpressure can be generated even if the gas leakage/loss in the source rock is up to 80% of the total gas generated. This suggests that the internal pressure seal of the source rock is not a critical factor on the pressure change as long as the source rocks are capable of sealing liquid oil. The equations were applied to evaluate the overpressure in the Eocene–Oligocene Enping Formation source rocks due to hydrocarbon generation in the Baiyun Depression, the Pearl River Mouth Basin by considering the source rock properties, hydrocarbon generation history, and hydrocarbon expulsion timing. Two episodes of overpressure development due to gas generation and release were modeled to have occurred in the Enping Formation source rock since 16 Ma. The overpressure release at 10.2–5.3 Ma via hydrocarbon expulsion was apparently related to the Dongsha phase of tectonic deformation, whereas the pressure release at 2–0 Ma was due to pressure generation that was exceeded the fracture‐sealing pressure in the source rocks.     

The Geopolitics of International Reconstruction: Halford Mackinder and Eastern Europe, 1919–20

This paper aims to reassess the role played by Sir Halford Mackinder (1861–1947) in the reconstruction of Eastern Europe after the First World War, highlighting a key issue behind the formation of his popular geopolitical ideas about the Eurasian ‘heartland’. Influenced by the democratic spirit of the early inter-war years, Mackinder used his geographical expertise in support of a loose federal reorganisation of the vast region between Germany and Russia, hoping to create a new, balanced international system capable of guaranteeing freedom and stability on the European continent. In 1919–20, this ambitious design became the basis of a short diplomatic mission to South Russia, where Mackinder tried to create a large regional defensive alliance against the Bolshevik regime externally supported by the Western powers. But the military weakness of local anti-Bolshevik forces and the political inconsistency of the British government led to the complete failure of this great imaginative project, revealing all the strategic limits and ideological flaws of Mackinder's geopolitical views on Eastern Europe.     

The Social and Economic Complexity of Ancient Jerusalem as Seen Through Choices in Lighting Oils

This paper presents and discusses the results of residue analysis conducted on 78 ceramic lamps found in archaeological excavations in ancient Jerusalem, in an attempt to identify the types of oils used and the reasons for their preferential choice. The oil lamps chosen for the study were taken from a variety of contexts, which represent the different periods during which Jerusalem was settled and the different sectors of the city. The results of the study show that even the most mundane activity of lighting using oil held within it social and economic choices, as mirrored in the different excavation areas.     

West European Countries and Their Foreign Policy in the Views of the Russian Liberals of Mid-to-Late Nineteenth Century

The article analyses the perception of the mid-to-late nineteenth-century Russian liberals of the West European states and their foreign policy of the time towards Russia. The article discloses the main features and differences in assessing the West and Russia as its part. It allows to reveal such features in Russian liberalism as common provisions and values typical of world liberal theory and a number of special features which resulted in developing different schools of liberal movement in Russia. The article underlines that the range of liberal ideas varied from selective borrowing of some elements of the western political system to their complete adaptation in Russia. The article focuses on the opinion of a number of national-oriented Russian liberals of the time who put forward a priority task to modernize the country, to implement liberal reforms, but not to strengthen its foreign policy power which, according to them, prevents improving well-being of the people and social stabilization.

The study allows to define a main vector of the ideological pursuit of the Russian liberals, the part of whom tried to enroot the liberal ideas in the backward peasant country.     

Cross-cultural contact in Manchuria: approaches to lives in between, 1900s–1950s*

ABSTRACT

This article aims to uncover the lives of some of the individuals who, through the occupational and personal choices they made, moved between the Chinese and Russian societies of Manchuria (Northeast China) in the first half of the twentieth century. The Chinese Eastern Railway, which passed through the region and was central to its economy, provided the main framework for Chinese–Russian contact. Headquartered in Harbin, the Railway generated a need for interpreters and translators, while it also offered opportunities for commercial go-betweens. Russian schools employed Chinese teachers for language instruction. After a change in the balance of power, by the 1920s, Manchurian warlords hired former tsarist officers and soldiers into their armies. The article compares the functions of intermediaries in this region to the better-known examples of Shanghai, Canton and Hong Kong. Research on ‘compradors’ has been more often conducted in these geographical settings, whereas the roles of cross-cultural intermediaries in late imperial and republican China still remain relatively unexplored.     

Hydrogeochemical dynamics affecting steam‐heated pools at El Chichón Crater (Chiapas – Mexico)

El Chichón is an active volcano located in the north‐western Chiapas, southern Mexico. The crater hosts a lake, a spring, named Soap Pool, emerging from the underlying volcanic aquifer and several mud pools/hot springs on the internal flanks of the crater which strongly interact with the current fumarolic system (steam‐heated pools). Some of these pools, the crater lake and a cold spring emerging from the 1982 pumice deposits, have been sampled and analysed. Water–volcanic gas interactions determine the heating (43–99°C) and acidification (pH 2–4) of the springs, mainly by H₂S oxidation. Significantly, in the study area, a significant NH₃ partial pressure has been also detected. Such a geochemically aggressive environment enhances alteration of the rock in situ and strongly increases the mineralization of the waters (and therefore their electrical conductivity). Two different mineralization systems were detected for the crater waters: the soap pool‐lake (Na⁺/Cl^? = 0.4, Na/Mg>10) and the crater mud pools (Na⁺/Cl^? > 10, Na/Mg < 4). A deep boiling, Na⁺‐K⁺‐Cl^?‐rich water reservoir generally influences the Soap Pool‐lake, while the mud pool is mainly dominated by water‐gas–rock interactions. In the latter case, conductivity of sampled water is directly proportional to the presence of reactive gases in solution. Therefore, chemical evolution proceeds through neutralization due to both rock alteration and bacterial oxidation of ammonium to nitrate. The chemical compositions show that El Chichón aqueous fluids, within the crater, interact with gases fed by a geothermal reservoir, without clear additions of deep magmatic fluids. This new geochemical dataset, together with previously published data, can be used as a base line with which to follow‐up the activity of this deadly volcano.
