城市体系研究主要关注城市的节点性与城际关系两个方面,而城市网络研究将这两个关键要素统一起来,为进一步探讨此问题提供了新的思路。通过城际联系的视角,本文从城市的“中心性”和“中介性”两个维度来重新定义城市的节点地位。基于此,研究分析了铁路交通流视角下近十年来中原城市群城市体系整体和局部的结构变化,试图提供一种网络视角下城市体系演变的不同图景。研究发现:①城市中心性和中介性呈现出截然相反的变化趋势;②高中介性的门户城市更易提升自身地位;③城市中心性的层级结构愈发显著,而中介性更加扁平。在一体化建设的背景下,研究讨论了中原城市群城际体系演变的特征与问题。 相似文献

Russia has tried to use economic incentives and shared historical and cultural legacies to entice post-Soviet states to join its regional integration efforts. The Ukraine crisis exposed the weaknesses of this strategy, forcing Russia to fall back on coercive means to keep Kiev from moving closer to the West. Having realized the limits of its economic and soft power, will Russia now try to coerce post-Soviet states back into its sphere of influence? Fears of such an outcome overestimate Russia’s ability to use coercion and underestimate post-Soviet states capacity to resist. Rather than emerging as a regional bully, Russia is trying to push Eurasian integration forward by becoming a regional security provider. The article relates these efforts to the larger literature on regional integration and security hierarchies – bridging the two bodies of theory by arguing that regional leaders can use the provision of security to promote economic integration. Despite initial signs of success, we believe that the new strategy will ultimately fail. Eurasian integration will continue to stagnate as long as Russia’s economic and soft power remain weak because Russia will be unable to address the economic and social problems that are at the root of the region’s security problems. 相似文献

Since the 1980s, several studies of post-war British propaganda have been published. While many of these have focused on developments abroad, some have explored domestic work carried out under the auspices of the Central Office of Information. Established in 1946, the Central Office of Information provided a range of services to government departments, including advertising and public opinion polling, but it was just part of a wider system of official communications that has tended to attract less attention in the historiography. Reorganised by Clement Attlee’s post-war Labour governments, this system was presented to the public as a means of disseminating impartial and apparently non-controversial ‘facts’ about government policy. Few commentators today accept that justification, but little is known about why it emerged after the Second World War or what impact it had on existing communications machinery. Taking a broad view of the subject that considers the inter-war and wartime antecedents to the post-war communications system, this paper seeks to fill in some of the gaps that have emerged in the literature. Focusing on shifts in official nomenclature and departmental practice, it explores the relationship propaganda shared to government policy and its broader legacy in the twentieth century. 相似文献

This paper examines negotiations involving the exchange of envoys between the Qing dynasty and Khoqand in 1759-60. The Qing made contact with Khoqand in order to bring rapid stabilization to the newly acquired western territories. Khoqand, on the other hand, established a relationship with the Qing in order to expand their authority over the Kirghiz, and to advance toward Bukhara. Irdana tried to take advantage of Qing authority for the purpose of expanding his territories, but at the same time, he appealed to the other Central Asian Muslims to engage with him in a "holy war" against the Qing. It is true that each power in Central Asia shared a sense of crisis in reaction to the Qing's sudden expansion to the west. However, we also need to examine the competition for hegemony among the powers under the pretext of opposition to the Qing's advance. 相似文献

The Italian Bell-Beaker (Final Copper Age) has been widely studied, yet little is known about its archaeofaunas. Reported are the results of the analysis of the archaeofauna from Semitella, which is one of the largest and most important Bell-Beaker sites in Italy. The site yielded an intentionally buried bovine skeleton and contained many pits, scattered throughout the excavated area. These pits may have originally contained the corpses of the animals whose bones are represented in the sample. The hypothesis is that Semitella was a sort of cemetery for animal carcasses, or a dumping ground where carcass discards and animal cadavers were thrown or buried. A careful taphonomic and zooarchaeological analyses were therefore mandatory. The study confirmed the hypothesis. It in fact revealed a poorly diversified, selected fauna, dominated by domestic taxa, matched to a strikingly low incidence of bone surface modifications, which is the expected state of bones that have been rapidly subtracted to biostratinomic agents. The accumulated evidence indicates that Semitella was a dumping and/or a burial ground for animal corpses in the surroundings of a nearby settlement. The assemblage's final arrangement is the result of floodings that removed the disarticulated skeletal parts scattering them downstream. What remains unresolved is whether, or not, the burials were connected with ritual practices. 相似文献
