The article focuses on the redevelopment of previously developed land by public-private sector partnerships in three cities/towns in South-West England, two of which can be described as medium-sized places with little previous experience of such developments. In each case we situated the redevelopment process in its wider multi-level and horizontal relationships using Social Network Analysis to produce network and centrality maps to reveal the complex network of relationships the process was embedded within and shaped by. These developments took place in what is termed the ‘roll-out’ phase of neoliberalism and we illustrate how the overarching planning and regulatory regimes (including contracts), along with wider economic conditions, shaped the development process, with the proviso that in each case these factors were mediated and themselves shaped by the assortment and interaction of local organizational, political, economic and civic forces. These included local planning committees and their interpretation of planning regulations and the developers involved, but also opposition to the developments from local sources. Much, however, depended on the ‘capacity to act’ of the relevant partnerships, in the sense of mobilizing and deploying available resources to realize the proposed developments.  相似文献

This paper argues that portable X‐ray fluorescence spectrometry (pXRF) is a suitable elemental measurement technique to study the production of copper‐alloy artefacts. However, rather than try to imitate the accuracy and precision of laboratory techniques, it is more beneficial to deploy it in a survey role, one that attempts to model chronological and geographical changes within large quantities of artefacts. To achieve this, it was investigated to what extent corrosion and the issues surrounding surface measurements affect the potential of this type of research. Analyses on early Roman period brooches gathered in the Nijmegen region of the Netherlands were subsequently compared with published data.  相似文献

The paper analyses the emergence of the Artificial Intelligence (AI) cluster in Montreal and investigates two questions: (1) What are the different theoretical interpretations related to the emergence of industrial cluster? And (2) What are the factors underlying the emergence of the AI cluster in Montreal and to what extent have local and global factors been decisive in this respect? The AI cluster emerges through a process that brings into play the interaction between the local initial conditions and the birth of a new industry. Moreover, it also involves an interaction between the local and the global, which is supported by interactions with foreign actors located in different parts of the world.  相似文献

Since the 1950s, US strategic architecture in the Indo-Pacific has been premised on its hubs-and-spokes model of bilateral alliances and security partnerships. Since the 2000s the US began working toward forging deeper interrelationships between its regional allies and partners. The emerging strategy ultimately aims to interlink long-standing allies like Japan and Australia, and also non-traditional partners in the development of a security network capable of maintaining the regional ‘rules-based order.’ In analysing the US-led triangular Indo-Pacific geometry, this article considers the prospects of an evolving and substantive US–Australia–Indonesia security trilateral. It does so by utilising Miller’s ‘conditions for cooperation framework’ to test the likelihood of greater cooperation between these three states. These conditions include cultural similarity, economic equality, habits of international association, the perception of common danger, and greater power pressure. It concludes that while there remain strict limitations on any formal alignment between the ANZUS partners and Indonesia, there are convergent interests in key sub-strategic areas in the maritime space and thus a viable path toward greater trilateral cooperation but not, as yet, formal arrangements.  相似文献

In this essay David Lewis Schaefer summarizes and defends the argument set forth in his book The Political Philosophy of Montaigne (Cornell University Press, 1990; second edition 2019) that Michele de Montaigne's Essays (first edition, 1580) merits consideration as a founding text of modern political liberalism. After responding to the most extensive published critique of his interpretation (by James Supple) and citing other recent studies that harmonize with his argument, Schaefer compares his analysis of Montaigne's political aims and political-ethical teaching with those set forth in two other recent studies: Philippe Desan's Montaigne: A Life and Pierre Manent's Montaigne: La Vie sans loi.  相似文献
