在明代,由于水患频发和长江主泓变动等原因,湖广武昌府城沿江江岸屡屡崩陷,当地政府遂启动江岸修筑工程。考诸史志,明代武昌府城的江岸修筑主要约有四次,分别是正统七年(1442)、成化三年(1467)、万历十七年(1589)和万历三十四年(1606)。最终修成的江岸,自武昌府城南门望山门外(今武昌解放路南端解放桥附近)起,向西折至江边,又沿江边中经黄鹤矶向下游延伸至坛角地区(今武昌和平大道武汉工人文化宫以西),长约5公里。这条堤岸确定了武昌城沿江江岸的基线,将武昌城的城市空间扩展到江边,并延续至今。  相似文献

Most research on urban planning, policy and development only considers legal practices and actors, and treats illegal ones as insignificant anomalies, unable to structurally affect the governance of urban space. However, this approach is inadequate for explaining urban governance in contexts (e.g. several countries in the Global South, the former Soviet bloc and Southern Europe) where illegal practices such as corruption and organized crime infiltration are widespread in many public and economic sectors. This paper addresses the role of illegal actors and practices in urban governance in the Italian context, using urban regime theory as the theoretical frame of reference. The research centres on the analysis of two case studies in the city of Rome (the In-between world investigation of a criminal network that had infiltrated the local administration and shaped several urban policies, and the investigation of episodes of corruption related to the project for the new A.S. Roma soccer stadium). It shows the existence of two shades of ‘grey urban governance’: firstly, the presence of a dark urban regime, centred on a criminal organisation and parallel to the ‘regular’ one; secondly, the use of corruption as a customary practice with which real estate entrepreneurs influence municipal decisions. Overall, this research contributes to moving away from a rhetoric of ‘gentlemanly’ urban capitalism and politics, and suggests the need to revise several aspects of urban regime theory – as well as other approaches to urban governance dynamics in general – in order to incorporate the role of illegal actors and practices.  相似文献

Knowledge about the Inca measurement system is based on information from the colonial chronicles and modern studies of the 16th-century Quechua dictionaries. Based on those texts, we can presume that the Incas used an anthropometric system of measurement adopted from the proportions of the human body. Using cosine quantogram analysis and statistical verification, it is possible to verify the existence of the measurement system used by the Inca architects. For this purpose, a measurement series of architectural and water infrastructure elements were collected from 3D point cloud of the Chachabamba and Machu Picchu settlements in Machupicchu National Archaeological Park.  相似文献

In this work, we apply a systemic approach to the analysis of a particular geographic territory, the industrial district. We are particularly interested in analysing the interaction between the productive-technological environment and the scientific environment by an examination of research contracts and patents. Our analysis shows that R&D activity in the Spanish ceramic tile District Innovation System was mainly conducted by suppliers. Final producers’ innovation efforts were related to non-technological aspects and differentiation.  相似文献

New industrial innovation policies like smart specialization aim at boosting economic growth by diversification towards more complex and higher value economic activities. This paper proposes a conceptual and analytical framework to support the design and implementation of such policies considering place-specific preconditions, particularly the differentiation of the regional system of innovation and entrepreneurship and the degree of current industrial diversification. The paper expands on the links between these preconditions and the barriers and opportunities for industrial diversification. Consequently, it proposes an archetypical place-based policy framework covering overall policy objectives as well as measures at the level of actors, networks, and the institutional and organizational support structures.  相似文献

Regime theory provides a framework for exploring changes in development patterns and internal dynamics of growth coalitions. Academic debates on sport and urban development have focused on large American and European markets, where such venues are increasingly led by urban regimes that aim to leverage public goals through private investment. Based on a detailed qualitative analysis of four projects in three major Israeli cities, this work examines a different typology of sport venue development – ‘public regime’, which operates in a small market context. The Israeli public regime neither allows the private sector to assume central roles in the design, development and operation of venues nor does it stimulate real estate development anchored by the venue. The assumption that professional sports is not a viable business in small markets is used to justify the public monopoly that regards the venues as public amenities, legitimizing the lack of strategic and business plans, producing benefits for the local political elite but doing little to stabilize professional sport and secure economic returns for the public. The more affluent city of Tel Aviv demonstrates a breakout from a pure public regime, where public control is retained but more business-oriented considerations are incorporated.  相似文献

ABSTRACT

This article examines cultural policy strategies supporting urban regeneration, focusing on its particular characteristics in the Ibero-American context. We start by developing a systematic contrast between the different circumstances that have led to the emergence of these strategies in the Ibero-American sphere and in other parts of the world. Our examination of the Ibero-American regenerative experience also includes a consideration of the paradigmatic cases that arose initially in the Iberian Peninsula and the typological analysis of subsequent Latin American experiences. The consideration of all these different elements ends up providing a global vision of the specificity of the phenomenon in its Ibero-American context.  相似文献

This article argues that warfare has been marginalised in theories of nationalism but that in conjunction with nationalism is vital for understanding the rise of nation‐states, the formation of nations and the nature of the international system. It offers a critique of statist approaches, suggests mechanisms through which warfare may sacralise nations and explores different patterns of nation‐state formation as they affect the interstate system. In particular, it emphasises tensions between state and nation‐formation as activated by the fortunes of war and the destabilising effects of waves of imperial dissolution, which are accompanied by patterns of re‐imperialization. It suggests that it is simplistic both to claim that war has led to a transition from empires to nation‐states and that contemporary practices of war‐making have led to a postnational era.  相似文献
