ABSTRACTRelational networks and intangible factors are crucial elements for the competitiveness of a territory. Public–Private–Partnerships (PPPs), in particular, allow for the provision of goods and services that favour the exploitation of complementarities between public and private resources. They aim at promoting an increase in the overall efficiency of investment projects through a complex mechanism that distributes risk and revenues among stakeholders. This paper examines the local and territorial determinants of PPPs through an econometric analysis based upon Italian municipal data, grouped at the provincial level. Using a tobit model, we analyse the relationship between the realization of successful PPP initiatives and different sets of factors, including less analysed local and territorial determinants. We stress the role of the local management of infrastructure assets, the administrative efficiency of local authorities and the diffusion of previous local development initiatives. Local management and territorial context factors explain most of the occurrence of successful PPP initiatives in the pre-crisis period while usual determinants (infrastructure endowment and financial distress) display a weaker effect. 相似文献

This article examines the attempts by the Dundee jute industryto recruit women workers in the years circa 1945–1954.It locates its discussion of these attempts in the literatureon the impact of the Second World War on the participation ofwomen in the British labour market more generally, and the forcesdetermining that participation. It stresses the peculiaritiesof jute as a traditional major employer of women operating invery specific market conditions, but suggests that this casestudy throws light on the broader argument about the impactof war and early post-war conditions on women's participationin paid work. 相似文献

ABSTRACTThe problems China faced in the world order after World War I and the position and measures China took in the tussling between Western countries needs to be analyzed not only using historical records in Chinese and from the perspective of China itself; researchers should also consult foreign documents to determine the attitudes and ways of thinking of other countries, so as to reflect on the choices China needed to make and the roles that Western countries played at that time. Only in so doing can we fully understand how much space and strength China then had to strive for its rights in the international arena. This article examines the social basis of the attitude and policies of the United States (US) towards China in the period between the May Fourth Movement (1919) and the Washington Conference (1921–1922) by focusing on reports on China in the US mainstream media, including the New York Times, the Christian Science Monitor, the Washington Post, and the Los Angeles Times. The US government’s attitude towards China was determined by the interests of the United States, the Far East, and the other countries of the world. However, the US mainstream media’s reports on China also reflected the values of American society and popular sympathy for China’s destiny. When discussing how to support China, the US media distinguished between support for the Chinese government and support for the Chinese people on the way to democracy and governance by law. In this case, the media reflected different views on how to assist China. 相似文献

莫高窟第76窟内的八塔变图像出现于宋初时期,其粉本应是中印佛教交流过程中由印度僧人传至敦煌的。而这一题材绘入洞窟时正处在敦煌末法思潮盛行的背景之下,作为正法象征的八塔变壁画蕴含了信众渴求佛法不灭的心愿。同时,莫高窟第76窟作为大族营建的家窟,具有举办佛事活动的功能,八塔变与窟内其他题材的相互联系能够更好地服务于信众的信仰实践活动。 相似文献

大都市中心区生产性服务业集群的空间溢出——以广州市天河区为例 总被引:1,自引:0,他引:1
空间溢出对产业集群形成发展具有重要意义。但空间溢出对生产性服务业集群的影响机制并不清楚。本文基于1 km×1 km网格和2013年广州市中心区--天河区的企业经济普查数据,采用空间数据分析技术,识别生产性服务业集群,分析集群特征,探测集群溢出类型。结果发现:①生产性服务业集群区位指向大城市中心区的核心地域,具有五种集群类型分异,空间呈不完全耦合。②生产性服务业集群空间规模受Jocobs型和MAR型两种溢出调控,在MAR型溢出作用下的集群空间规模相对较小。③信息服务业集群的溢出为负效应说明溢出作为一种潜在利益,在转化为集群优势的过程中存在过滤效应。 相似文献

The authors describe the discovery of the remains of two unidentified skeletonised individuals in a small town located in southern Italy. The bodies were discovered while workers were preparing to lay an oil pipeline. The two individuals were found at a depth of 2 meters, and in very close proximity to one other. The recovery process of the skeletonised remains and their related findings, carried out by a team of forensic anthropologists and archaeologists, is described here.Archaeological examination determined that the remains date back to the 4th millennium B.C. Forensic anthropological and odontological examinations were performed to determine the biological profile of the skeletal remains by estimation of age and height, as well as the determination of sex. Age determination was performed by the Kerley and Ubelaker (1978, Revision in the microscopic method of estimating age at death in human cortical bone. Am. J. Phys. Anthropol., 49, 545–546) histological method using a 1 mm thick piece of bone tissue taken from the diaphyses of femur in both individuals. Dental age was estimated by examining root transparency. In order to determine the height of the individuals, various research methods based on the dimensional values of particular skeletal structures were applied. DNA analysis showed genotype differences of all the systems as compared to the haplotypes of present day subjects. This provided confirmation that the skeletal remains were from individuals of an ancient population (4th millennium B.C.). In addition, radiocarbon dating provided useful information as to the approximate period of death of the individuals. Interpretation was further enhanced by analysis of various bone fragments from each of the skeletons by high resolution mass spectrometry. 3D computerized imaging was used to analyse the patterns of skull fractures present, which resulted in supporting the hypothesis that the fractures were caused by stoning. 相似文献
