This article introduces our themed section on The Left(s) and Nationalism(s), which provides a comparative analysis of the relationship between nationalism and different left-wing parties in Western Europe. It highlights the innovative comparative perspectives offered by this themed section, which not only concerns a series of different geographical cases studies but also involves the ideological plurality of the Left. The larger research question that our contributors address is how different left-wing parties have dealt with the inherent ideological tension between the universality claimed by the Left and the particularism inherent in nationalism, as a doctrine and a principle of political legitimacy. The article stresses three main contributions of our themed section: (1) Western European left-wing parties do engage with the themes of nationalism and nationhood, but they often rely on convenient silence to solve some of the contradictions with their progressive ideology. (2) None of these parties have formulated thick versions of the respective national identities. (3) State-wide left-wing parties have used instrumental conceptions of nationhood to address the challenge of separatist parties, but only with mixed results.  相似文献

We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies.  相似文献

Non-urbanized areas (NUAs) play an important role in reducing the effects of climate change by providing both carbon storage and sequestration. Urban areas are responsible for the emission of 60% of global greenhouse gas, 50% of which are produced by buildings. During the past decades, increasing urban growth and sprawl processes produced several urban layouts characterized by different morphological features and a common lack of sustainable energy and environmental solutions. Investigating the relationship between urban morphology, energy demand and carbon emission/sequestration represents a relevant topic for urban planning practices implemented to face urban climate change effects. This study proposes a method for a transformability assessment aimed at investigating the transformation suitability of different urban morphology types. The case study is the metropolitan area of Catania (Italy), characterized by an impressive urban growth since the 1960s. The proposed method identification of limits and options for increasing sustainability of urban areas considering the contribution of both NUAs and built-up areas. This approach allows to identify appropriate planning tools for new layouts of urban fabrics while increasing the objectivity of the decision process. In the framework of climate change mitigation and adaptation, the outcomes of this research may lead to innovative urban planning practices.  相似文献

Based on a study in four Norwegian cities (Oslo, Stavanger/Sandnes, Bergen and Trondheim) differing in size and centre structure, this article illuminates how residential and workplace location, local-area density and transit accessibility influence different aspects of travel behaviour. We find strong effects of residential and workplace distance to the city centre on overall driving distances and commuting distances. We also find clear effects of local area densities around residences and workplaces on the choice of car as a travel mode, along with less pronounced effects of the distance from dwellings and workplaces to the city centre. In the cities with the best developed transit provision, we also see clear effects of transit accessibility at the residence on the propensity of choosing the car as travel mode. The results provide strong support of Norwegian national policies of urban densification as a planning strategy to curb the growth in urban motoring. However, although the influences of urban structure on travel show many similarities across the four cities, there are also important differences reflecting variations in centre structure (predominantly mono- or polycentric) and population size. The magnitude of the influences of various urban structural characteristics on travel behaviour are thus highly context-dependent.  相似文献

ABSTRACT

This paper employs δ13C and δ15N analysis of bone collagen to explore animal management at large Norse settlement sites in the liminal environments of the Scottish North Atlantic Islands. The Norse period was a time of social, cultural and economic change; the need to feed an expanding population and the demand for trade meant that domestic stock were a crucial resource. Our results indicate that rearing animals in these challenging insular environments required careful management. At all sites, the diet and movement of domestic cattle and sheep were highly similar and carefully controlled and, despite many of the analysed settlements lying close to the coast, there was no use of shorefront grazing or fodder resources. In contrast, pig rearing strategies varied across the island groups. In the Western Isles pig diets were diverse, indicative of household or ad hoc management, whilst on Orkney all pigs consumed a more restricted diet based primarily on terrestrial protein. A comparison of red deer with domestic stock on the Western Isles indicates that both groups were exploiting similar grazing niches.  相似文献

The child-friendly city advocates for children's ‘right to the city’. Much of this advocacy focuses on the independent child, with little attention paid to the accompanied experiences of younger children, such as those travelling in prams. This paper draws on a material feminist perspective to help address this gap. We offer the concept of mother–child–pram assemblage to bring to the fore the corporeal dimensions of everyday pram journeys. By analysing sensory ethnographic materials collected with mothers and young children living in Wollongong, Australia, this paper highlights how the ‘affective affordances’ and ‘affective atmospheres’ of pram mobilities shape urban experience by reference to how motherhood and childhood are achieved on-the-move. We conclude with policy-relevant insights for the child-friendly city.  相似文献

The presence of single and also of married British women in overseas colonies, especially those employed by or married to men in the Colonial Service in the later colonial period, has been the subject of scholarly enquiry. Their lives, roles and values and their distinctive contribution, if any, to the development of empire and of its ending have been debated. Their gendered roles were usually subordinate in a masculine culture of empire, and especially as wives they are commonly regarded as marginalised. The archived records left by Lady Margaret Field reveal her commitment as a single woman to a colonial mission and her sense of achievement as a school teacher and educational administrator, while also acknowledging the independence and career satisfactions she subsequently lost when she married a senior Colonial Service officer who rose to be a governor. But it is also apparent that, though incorporated and subordinate as a governor's wife to her husband's career, she was not marginalised to a separate sphere. As is evident from this case study, governors’ wives had important and demanding political duties, and such responsibilities need to be acknowledged.  相似文献

基于快递物流测度的区域流动空间特征——以江苏省为例   总被引:1,自引:0,他引:1

在信息技术推动下,流动空间作为新时期的新空间形式在带来时空压缩效应的同时不断地强化着区域城市间联系,推动着社会经济资源的城际流通。快递物流是互联网交易的虚拟流与快速交通实体流交互产生的物质流动,其代表了流动空间的虚实二元性,是研究流动空间网络特征的有效切入点。以江苏十三个城市为研究区域,以六家物流公司的网站数据为数据来源,采用权重分析法和重力模型方法建立起区域城市的快递物流水平、城市间流动空间连接度及城市快递物流总体评价等三项指标,结合区域流动空间的指标分析发现区域流动空间具有网络一体化、去中心化、扁平化、等级化及点轴式等五大特征,基于流动空间的可视化研究发现江苏省区域城市间关系显示出了一个具有等级特征的多中心扁平化点轴网络,围绕南京、苏州、徐州的都市圈一体化发展态势成为提高区域流动空间流动能力的重要突破方向。  相似文献

清末地方自治包括府厅州县和城镇乡地方自治两个层级,并建构了两个层级不同的官治与自治模式,即在城镇乡一级实行"以自治辅助官治",而府厅州县则实行"自治与官治合并"之制度。两种模式都借鉴了日本自治制度,但都有所不同。就清末城镇乡地方自治的运行来看,由于地方自治章程赋予官府监督自治之权,也由于自治团体为谋求地方利益,常常也会与官府对立,所以,官治与自治常常处于矛盾冲突之中。  相似文献
