Field measurements of atmospheric absorption made in the wavenumber range 5–17 cm−1 are found to have values in excess of prediction based on absorption by monomeric water molecules. The measurements also show unexplained variations with time, although on average the absorption in the region of 7.1 cm−1 is found to be close to comparison laboratory values. The absorption measured in excess of water monomer prediction is analysed for its dependence on temperature. In common with the laboratory results, this is found to differ from prediction for water dimers in equilibrium. Results are also given for measurements in fog conditions.  相似文献

Abstract

The little-known ‘great escape’ of Allied prisoners-of-war (some 50,000) held in Italian camps at the time of the armistice of 8 September 1943 provides the starting-point for a fresh interpretation of popular and peasant experience during the emergency of 1943 – 5. The article explores some of the main aspects of the ‘strange alliance’ between Allied fugitives and the Italian population, with particular attention to the mutual symbolic appropriation between former ‘enemies’ in the midst of a civil war and related collapse of the state.  相似文献

This article investigates how the successive mayors of Hiroshima and Nagasaki have worked to institutionalize their collective memory of the nuclear bombings in the United Nations since 1976. Increased institutionalization of the memory in the UN can serve to influence the value system shared by diplomats engaged with nuclear disarmament by making remembrance activities surrounding that memory obligatory. With their moving testimonies, the mayors of Hiroshima and Nagasaki have primarily promoted Hiroshima and Nagasaki remembrance in the UN by tapping into the moral authority traditionally credited to survivors or witnesses of atrocity. They have been largely successful in achieving institutionalization; however, UN institutionalization of Hiroshima and Nagasaki remembrance does not automatically transform into a global collective memory without also being accepted at the national level.  相似文献

Peripheral regions commonly appear to be less attractive to live in and policymakers all over the world are applying various measures to make them more attractive. This paper analyzes the effects of two very different measures: The German municipal fiscal equalization scheme and the German structural funds for economically weak areas (GRW). It focusses on the impact on perceived quality of life, measured through interregional migration between German labor market regions. Using a spatial vector autoregressive panel model, we find evidence that equalization transfers have a significant positive impact on regional net migration and contribute to the aim of regional equity. These effects are especially found for regions with low endogenous fiscal capacities. GRW funding reveals no significant effects on net migration rates in total, but short-term effects in rural regions.  相似文献

In the early 1970s, there was scarcity in the world grain market, soaring prices and famines in several countries of Asia and Africa. The commercial grain trade was expanded at the expense of food aid. After a brief look at policies addressing the situation in terms of modernised methods of agricultural production for small producers, the article sketches how such policies also affected relief efforts, from the low availability for food aid, the provision of food that was not useful and late deliveries through efforts to tie food aid to local changes in agricultural production and settlement patterns. In part, food aid thus reinforced processes of social differentiation that had contributed to causing the famines in the first place.  相似文献

A non-equilibrium radiative transfer model has been applied to the 2.7 and isotopic 4.3 μm bands of CO2, together with that of H2O at 6.3 μm and the first excited vibrational levels of the nitrogen and oxygen molecules. The radiative transfer has been treated by a modified Curtis matrix method that allows inclusion of non-thermal sources, such as vibrational-vibrational energy exchange. The populations of the different levels have been obtained by solving a system of coupled equations, including those for the 15 μm bands. Results from the model are compared to previously reported results. A detailed study of where solar energy initially absorbed by CO2 bands finally goes is also presented.  相似文献

During the second half of the nineteenth century and the first third of the twentieth century, Spain, along with some other European countries, underwent a process of transition regarding water resources management. One of the most obvious transformations that occurred during this period was the increasing lead taken by the government in the building of large hydraulic structures and the subsequent decrease in the influence of private initiative in this matter. The government's aim was to exploit the water resources provided by the rivers to their full, and in particular to use the water that was destined for irrigation to maximum effect. The repeated failure of projects promoted by private companies led the government, not without problems, to enact regulations and create hydraulic plans to be put into motion by the public sector. This change in focus is the key to understanding the frenetic pace of hydraulic infrastructure construction that occurred later and which made Spain one of the world's leading nations in terms of indicators such as the number of large reservoirs in use. This article focuses on the transition from private initiative to public intervention and evaluates the main stages of this process in Spain. The cases of the basins of the Muga and Fluvià rivers, located in the extreme north-east of the Iberian Peninsula in Catalonia, are described in light of this process. This research attempts to verify that despite their modest size and their distance from the main decision-making centres, these two cases reflected the situation at the national level. This was just one of the many local effects of the transition process of water resources management in Spain, even though the results of this transformation would be neither immediate nor effective in the short term.  相似文献

Previous studies on geographical distribution of economic activity in Turkey demonstrate that firms are localized in major metropolitan areas as well as a set of emerging regions. The aim of the paper is to complement the findings of the studies on regional and industrial concentration in Turkey's manufacturing industry by exploring whether regional specialization and industrial concentration patterns changed during the 1980–2000 period. The paper further aims to explore the driving forces of industrial concentration in Turkey's manufacturing industry, particularly during Turkey's economic integration process that started with trade liberalization after 1980 and further developed with the Customs Union in 1996. Regional specialization and industrial concentration are measured by GINI indices Turkey's NUTS-2 regions at the four-digit level for the years between 1980 and 2000. To investigate which variables determine industry concentration, systematic relation between the characteristics of the industry and industrial concentration is tested. Following the method proposed by Paluzie, Pons and Tirado, a panel regression equation is estimated, where the dependent variable is the Gini concentration index and the independent variables are the variables that represent the characteristics of the sectors that follow the predictions of classical trade theory, new trade theory and new economic geography. The major finding of the study is that during 1980–2000, Turkey's regions became more specialized and industry became more concentrated. Increases in the average values of regional specialization and industrial concentration support the prediction developed by Krugman hypothesis that regions become more specialized and industries become more concentrated with economic integration. In exploring the driving forces of industrial concentration, the findings demonstrate that firms tend to cluster in regions where there are economies of scale.  相似文献
