120急救医疗服务的站点选址是基本的设施区位问题.本文以广东省鹤山市为例,开展了关于城乡一体化地区120急救医疗站点区位的优化研究.首先根据2006年鹤山市120呼叫数量的实际数据研究了公众个人满意度随距离的衰减关系;然后在不同的优化原则下构建了两个满意度优化模型;最后.分别假设不同的站点数量设置,对两个模型进行了求解与比较.结果发现基于最小个人满意度最大化的模型Ⅱ虽然在总满意度上表现不佳,但具有较好的公平性,且可以用较少的站点满足给定距离范围覆盖所有的镇.  相似文献

The studies of urban popular culture in modern China in recent years have attracted wide attention from scholars in China and abroad. The symposium, which is composed by Ma Min’s “Injecting vitality into the studies of urban cultural history,” Jiang Jin’s “Issues in the studies of urban popular culture in modern China,” Wang Di’s “The microcosm of Chinese cities: The perspective and methodology of studying urban popular culture from the case of teahouses in Chengdu,” Joseph W. Esherick’s “Remaking the Chinese city: Urban space and urban culture” and Lu Hanchao’s “From elites to common people: The downward trend in the studies of Chinese urban history in the United States,” provide valuable insights on the perspective, trend, and methodology of the studies. Four articles of the symposium are translated by Yang Kai-chien and Jin Xueqin from Shixue Yuekan 史学月刊 (Journal of Historical Science), 2008, (5): 5–19; Joseph W. Esherick provides the English version of his article.  相似文献

Systematic surveys and excavations were carried out during the 1990–1996 field seasons in the Tadrart Acacus and surrounding areas, shedding new light on the climatic changes and cultural dynamics which occurred during the Holocene. In this paper, the geological, geomorphological, and archaeological evidence is assembled in order to provide a preliminary synthesis on the prehistory of the area. Pendant les saisons de terrain du 1990 au 1996, des récognitions et fouilles systématiques ont été conduites dans le Tadrart Acacus et dans les zones circonvoisines; ces études ont donne des nouvelles information en ce qui concerne les changements climatiques et les dynamiques culturelles de cette région pendant l'Holocène. Dans ce papier, les évidences géologiques, géomorphologiques, et archéologiques ont été intégrées afin d'obtenir une synthèse préliminaire sur la préhistoire de la région.  相似文献

What is the economic impact of joining a currency union? Is this impact heterogeneous across regions? And how does it change in case of a recession? We answer these questions by investigating the economic impact of joining the euro area for the latecomers, that is, the eastern European countries that adopted the euro after 2002. Differently from previous literature, we use NUTS-2 regions as units of analysis. This novelty allows us to investigate the theoretical predictions of a currency union impact at a more appropriate geographical level. Using a recently developed counterfactual approach, we estimate the overall as well as the disaggregated impact of joining the euro area. We find that the adoption of the euro brought about a small positive effect, which was, however, dampened by the Great Recession. Individual regional estimates suggest heterogeneous returns with benefits accruing mostly to core regions.  相似文献

Over the last decades, there has been a significant development towards new forms of multi-locality, particularly for job-related reasons. In addition to offices, many can work in multiple places (such as the home, co-working spaces, coffee shops and public libraries). In addition to workers in start-ups and small entrepreneurs, who are traditionally known to be more mobile, white-collar workers employed by organizations are increasingly becoming multi-local. However, little is known about the ways in which multi-locality is addressed within the urban regions. This phenomenon has been studied at Aalto and NMBU University within the BEMINE research project by analysing recent policy and planning documents, as well as organizations’ strategies within the Helsinki region. In addition to a literature review, a qualitative analysis of planning documents was conducted as well as semi-structured interviews with five organizations (both private and public) in Finland employing mobile white-collars. The findings reveal that while policy-makers and city planners have not yet addressed the complexity of multi-locality, both private and public organizations are focusing on more concrete multi-local strategies and working practices. More dialogue is needed amongst policy-makers, city planners and organizations to address multi-locality at different levels of analysis and planning.  相似文献

The massacre of Palazzo d’Accursio is considered one of the first events in the rise of the Fascist squads. This article analyzes the ways in which the event was described in Bologna during the twenty years that followed it. It is believed that in the first few years, commemorations that emphasized the role of the Fascist squads were not very common. Instead, they concentrated on the life of Giulio Giordani, a murdered lawyer and opposition councilor, who became a martyr. Members of the city’s ruling class, especially lawyers, developed their own rituals of commemoration, but the establishment of the regime led to the acquisition of the commemorations of Giordani by Fascism, reflecting the shift of the local elites towards Fascism. In the 1930s, the massacre began to be described with detailed reference to the violence carried out by the Fascists. This process coincided with a much more incisive occupation of the area of commemoration.  相似文献

The fortress of Arnara is a small castle in a high seismic hazard zone in Latium, Italy, which represents a landmark for the local population. It was chosen as a case study, being a perfect example of Middle Age fortress, well preserved during the centuries despite some strong earthquakes damaged it in the past. The project presented here is a significant example of how the interest of a community to regenerate an ancient structure for its re-use can pave the way to a complete structural strengthening, which includes anti-seismic concepts aiming at retrofitting the ancient fortress walls. The overall project joins architectural and structural solutions. The architectural solution aims at a functional reconfiguration of the spaces, so to attract the locals to reuse it, while at the same time highlighting some valuable architectural features of the fortress. The structural solution aims at improving the seismic resistance of the masonry walls with a structural intervention that is respectful and integrates with the existing forms. This was achieved by means of a tenso-structure that has the two-fold role of reconnecting the different portions of the structures and of endowing it with a distinctive architectural sign. This project demonstrates that rediscovery of architectural heritage can also be pursued by proposing a new use for these structures, following an appropriate regeneration strategy that must take into account the cultural features of the territory, being at the same time respectful of the past history of the buildings.  相似文献
