We develop a model in which two regional governments compete for two mobile oligopolistic firms. Regional governments provide local infrastructure to attract mobile firms in order to increase regional employment and income. Firms face the trade-off between better regional infrastructure and fiercer competition for local workers. Strategic interaction prevails at the regional level as well as at the firm level. We show that an equilibrium with spatial concentration of firms as well as an equilibrium with spatial diversification of firms exists. In almost all cases regional competition leads to a suboptimal provision of local infrastructure.  相似文献

ABSTRACT

In the second half of 2018, Austria for the third time has taken over the EU Council Presidency and is therefore particularly interested in promoting an image of itself as a reliable partner and a European country which accepts and protects European values. Foreign cultural policy is one of the suitable instruments for achieving this goal. The present paper analyses Austrian foreign cultural policy with the aim of finding out how European integration affects it. The paper uses qualitative research methods such as desk research, document research and expert interviews. The results of the analyses show that Austrian stakeholders traditionally consider Europeanization primarily as a tool to promote Austrian national interests on the international stage.  相似文献

The civilization of the children of the "savages" in the colonial world was seen as a crucial issue from early on was an inherent part of the colonization project in Africa, America and Oceania in the 19th century. The idea of civilizing "the savages," today's South, through children has continued in the post-colonial era with the development of mass-schooling systems and various child-focused development projects. This has led to an export of internationally defined standards for a "good childhood" through various foreign funded development programs in South. While many NGOs, legitimizing their work on the basis of the Convention on the Rights of the Child (CRC), are genuinely working for an improvement of children's conditions, they have also taken on the role as a second guardian in order to cultivate "proper" children and parents who can live up to the supposedly universal ideals of a "good childhood." The article adopts a critical view on the child rights movement by shedding light on the crucial role, which NGOs play as civilizing institutions in the South. The article specifically draws attention to the double-sided patronization of children and parents, and "infantilization" of nations in South, which implicitly lies beneath CRC and the child rights movement.  相似文献

Archaeological excavations in the Areni-1 cave complex in southeastern Armenia revealed installations and artifacts dating to around 4000 cal. BCE that are strongly indicative of wine production. Chemical evidence for this hypothesis is presented here using a new method to detect the anthocyanin malvidin that gives grapes and pomegranates their red color. Using solid phase extraction (SPE) and alkaline treatment of the samples, followed by combined liquid chromatography-tandem mass spectrometry (LC-MS/MS), this method was applied to authentic standards and four ancient potsherds from Armenia and Syria. A positive result was observed for two of the samples from the Areni-1 cave complex, adding evidence supporting the hypothesis that wine was produced in the Near Eastern highlands in the Late Chalcolithic Period.  相似文献

Freshwater bivalve shells are frequently identified in faunal assemblages from Neo-Eneolithic tell settlements along the Danube River valley in South-East Romania (5th millennium BC). Up until now, significant accumulations of freshwater bivalve shells have been identified only in household refuse areas of the settlements, where they form consistent shell layers. The origin and formation of such shell accumulations and, more generally, the role of bivalves in the animal economy of the prehistoric populations that inhabited the settlements, are poorly understood. Two freshwater bivalve shell accumulations were studied in household refuse areas of Eneolithic tell settlements, one at Bordu?ani-Popin? and the other at Hâr?ova tell. The occurrence of similar accumulations in the two settlements indicates generalized practices between the two communities. This first study of such accumulations addresses the relationship between bivalves and other animal species used in alimentation by the two Eneolithic communities, as well as the relationships between these communities, their environment, and the evolution of the settlements. Bivalves were harvested in the close vicinity of the settlements and large quantities were obtained only towards the end of the summer season. During this season there is an inverse relationship between high water levels in the river and the availability of bivalves for harvesting. Bivalves played an important role in the alimentation of the prehistoric populations – at Hâr?ova tell their contribution to alimentation in terms of energetic yield surpasses that of fish, at least for the short period of time represented by the stratigraphic sequence analysed. Bivalve shells were used, along with other types of household refuse, in construction techniques aimed at limiting soil humidity in the settlements and inside the dwellings.  相似文献

Burnt human remains excavated from a scoop feature from a cemetery at Teouma, Vanuatu in the western Pacific (∼2850 BP) were examined to assess the nature of the deposit. Possible scenarios explaining the reason the bone was burnt and interred were assessed using osteological signatures taken from archaeological, experimental, and forensic studies. The methodology of the study included recording color change, types of bone distortion, and element representation in conjunction with archaeological evidence. The burnt and fragmented human bone (n = 430, fragments weighing 620 g) represents a single adult individual. Macroscopic evidence from the bone indicates the body had been fleshed or fresh at the time of burning and element representation follows a similar pattern to other burials excavated from the site. Excluding burning, there was no evidence of human modification to the bone such as cut marks, percussion pits or peri mortem trauma suggestive of cannibalism. The archaeological evidence from the site indicates that the body had not been burnt in the place the remains were subsequently discovered. The combined macroscopic and archaeological evidence strongly suggests that the human bone was burnt as a result of a deliberate cremation of an individual. If a conclusion of deliberate cremation is accepted, this research represents the first case of a Lapita period cremation and demonstrates how a combination of methods can explain the nature of an archaeological deposit of burnt human bone when the cause is not otherwise apparent.  相似文献
