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

In this article, we use a dynamic spatial microsimulation model of Britain for the analysis of the geographical impact of policies that have been implemented in Britain in the last 10 years. In particular, we show how spatial microsimulation can be used to estimate the geographical and socio-economic impact of the following policy developments: introduction of the minimum wage, winter fuel payments, working families tax credits, and new child and working credits. This analysis is carried out with the use of the SimBritain model , which is a product of a 3-year research project aimed at dynamically simulating urban and regional populations in Britain. SimBritain projections are based on a method that uses small area data from past Censuses of the British population in order to estimate small-area data for 2001, 2011, and 2021.  相似文献
