ABSTRACT. This paper differentiates between centrifugal and centripetal aspects of ethno‐nationalism to help account for the ascendancy of communism in the immediate aftermath of World War II in Poland. It argues that the directing of social antipathy to defined out‐groups allowed the Polish Workers' Party (PPR) to manage social anger and that the Roman Catholic Church's ethno‐religious agenda was aligned with the PPR's ethno‐nationalist policy. Furthermore, it is contended that the Church's toleration of hostile actions directed at minority communities supported the PPR's management of social anger. The paper concludes that the Church, despite its manifest intentions and contrary to contemporary perceptions, played a role in the PPR's achievement of hegemony.  相似文献

ABSTRACT. Although alien rule is widely assumed to be illegitimate, nationalist resistance to it varies across time and space. This article explores why there was greater nationalist resistance to Japanese colonial rule in Korea than Taiwan from the turn of the twentieth century to the end of World War II. Resistance to alien rulers requires both a supply of participants in nationalist collective action and a demand for national self‐determination. The article assesses two principal propositions: (1) that the supply of participants increases to the degree that native elites are stripped of their traditional authority and offered few incentives to collaborate; and (2) that the demand for national self‐determination decreases to the degree that alien rule is fair and effective. A comparative analysis of the effects of Japanese alien rule in Taiwan and Korea suggests that nationalist resistance is greater in the earliest phases of occupation, that the greater native elites' opportunities, the weaker the resistance to alien rule; and that the fairer the governance, the weaker the resistance to alien rule.  相似文献

The spatial and temporal variability of nitrogen dioxide (NO2) concentrations and their relationships with meteorology was evaluated in the Toronto–Hamilton urban airshed. NO2 concentrations were highest in the early morning and late evening. Mean concentrations were highest in winter, although individual one-hour NO2 concentrations were found to be highest in summer. Wind direction was the strongest control on hourly NO2 concentration, and temperature and wind speed also had an effect. Our analysis of NO2 concentration variation by wind direction showed that areas downwind of major highways, urban centres and industry were exposed to higher pollutant concentrations. Seasonal patterns of NO2 concentration displayed significant spatial heterogeneity, in particular, in Toronto. Onshore winds sheltered coastal inhabitants from the full extent of NO2 exposure they would otherwise experience. Seasonal variations in meteorology and emissions mean that the degree of spatial variability in NO2 concentrations changes from season to season. This study will help to improve existing land-use regression-based NO2 prediction models by incorporating meteorological controls on NO2 distributions for health effect studies.  相似文献

The 7 February 2009 bushfires in the peri‐urban region to the north of metropolitan Melbourne heralded what many have called an entirely new epoch in terms of weather‐related disasters in Australia. A total of 173 people and 2000 properties were destroyed and, as with the 1939 fires in Victoria, a Royal Commission was subsequently instituted to inquire into the causes and responses to the fire. The Royal Commission has heard much evidence about alleged failings of fire response, communication and administration. It also considered land use planning issues and the associated regulatory framework. Using the Shire of Murrindindi as a case study, this paper argues that the location of population growth, and associated regulatory failure, are contributory, yet under‐researched, factors associated with life and property losses. The adoption of more robust planning tools which incorporate climate change considerations, we argue, is essential to anticipate and minimise the impacts of disastrous natural events such as bushfires. In the latter part of the paper, attention is drawn to a recent Victorian Civil and Administrative Tribunal decision which is groundbreaking in its use of the precautionary principle to prevent dwelling construction in an ‘inappropriate’ location as well as to some major inconsistencies between planning for flood and bushfire threats.  相似文献

For over fifty years relations between the United States and Cuba have been antagonistic, with each side blaming the other for the continuing impasse. This Caribbean Cold War has seen an unsuccessful armed invasion of Cuba (popularly known as the Bay of Pigs invasion), the threat of nuclear war between the US and the USSR (the ‘Cuban missile crisis’), and an intensifying series of measures by the US government to reverse the Cuban social and political revolution of the 1960s. Since the early nineteenth century Washington has sought to control Cuba; and the US conditions for relaxing its pressure on present‐day Cuba continue this tradition, itself part of a broader ideology (often short‐handed as the Monroe Doctrine) which sees the western hemisphere as America's legitimate and exclusive ‘sphere of interest’. This article examines a number of recent works dealing both with the US–Cuban relationship, placing this relationship in historical and geopolitical contexts, and with the impact on Cuban society of the economic crisis of the 1990s caused by the collapse of the Soviet Union.  相似文献

Anthropology has long been a contested field with roots in both scientific and humanistic discourse. The “four-field” approach in American anthropology has been used by some as a means of suppressing conflict and enforcing a false sense of unity. While critiques of the four-field approach are warranted, in fact holism represents anthropology's greatest strength. Anthropology gains a competitive advantage over other disciplines in its ability to combine biological and cultural approaches. Moreover, the four-field model, while historically contingent, is well suited to the institutional and political realities of the American academy, especially the public research university.  相似文献
