Before launching ambitious and expensive development programmes to induce new regional technology corridors and clusters, it is critical to appreciate existing spatial economic patterns in a region. Initial economic conditions drive location decisions of firms and a labour force such that any changes must intercede onto an existing landscape built for current economic conditions. This work adopts a simple regional economic model to integrate and review traditional and modern urban location theories in order to illustrate the power of initial conditions to determine a final result. A simple spatial dynamic simulation model captures many of the pertinent effects of real estate pricing patterns to frame both opportunities and constraints to re-shape an urban landscape. Attention to 'ground up' spatially correlated location patterns revealed in price data that suggests close attention to strategic zoning can have profound impacts on the success or failure of economic development. Relatively modest policy interventions that carefully utilize existing preferences for urban amenities and concurrent real property investments involve fewer policy risks with potentially more powerful stimulative economic consequences than promised in more ambitious programmes.  相似文献

Britain has been a nuclear-weapon state since the 1950s, mostly in extensive cooperation with the United States in equipment procurement, though (contrary to the aims of anti-nuclear campaigners) full freedom of operational action has been kept. The current force of four nuclear-powered submarines armed with Trident D.5 missiles is not expected to be dependably sustainable beyond the early or middle 2020s in key respects, and lead times mean that initial decisions on whether and if so how to maintain capability thereafter need to be taken by about 2010. The open debate for which the government has called will have to consider international obligations and likely repercussions, strategic and ethical arguments, options for renewal (including at reduced scale), the amount and incidence of costs, and opportunity costs. The government has not yet published enough information to underpin firm conclusions about continuance other than for 'true believers' either pro or con.  相似文献

Written for the Canberra Commission in 1996, the analysis outlines the genesis and evolution of the underlying theories that had such a profound influence on the nuclear arms race and US policies towards the Soviet Union. With that as background, it outlines the damaging effects that deterrence dogma had on western interests and world politics; considers whether those effects were peculiar to the prevailing circumstances or are inherent to the concept; and addresses the question of ‘stable deterrence’. Lastly, it dismantles the claim that nuclear weapons kept the peace and reviews the place of deterrence‐based policies in the future.  相似文献

This article presents, in a programmatic way, the histoire croisée approach, its methodological implications and its empirical developments. Histoire croisée draws on the debates about comparative history, transfer studies, and connected or shared history that have been carried out in the social sciences in recent years. It invites us to reconsider the interactions between different societies or cultures, erudite disciplines or traditions (more generally, between social and cultural productions). Histoire croisée focuses on empirical intercrossings consubstantial with the object of study, as well as on the operations by which researchers themselves cross scales, categories, and viewpoints. The article first shows how this approach differs from purely comparative or transfer studies. It then develops the principles of pragmatic and reflexive induction as a major methodological principle of histoire croisée. While underlining the need and the methods of a historicization of both the objects and categories of analysis, it calls for a reconsideration of the way history can combine empirical and reflexive concerns into a dynamic and flexible approach.  相似文献

Memorials cultivate a common understanding of the past that is communicated through the celebration of select people, places or events. Because memorials are located in public space and crafted from time‐defeating materials, the process of commemoration is inherently political. Scholars have studied this process to discover the agendas that inform the ideological content of memorials, but rarely how this content is received by its audience. This question is especially pertinent when memorials outlast the generation and the ideology that created them. This study attempts an answer by exploring the career of one memorial: the monument in St. Catharines, Ontario, dedicated to Private Alexander Watson, a casualty of the Battle of Batoche (1885). It finds that the monument's significance was transformed by political, cultural and historiographical shifts. While its local audience has forgotten its specific message, its generic intent to honour fallen soldiers is still recognized.  相似文献

NATO has throughout its history been the subject of prognostications of crisis and dissolution. Indeed, the alliance has been written off so many times that crisis as normality has come to typify its development. In the twenty-year history of NATO's post-Cold War development, Operation Allied Force stands midway between the existential moment that was the collapse of the Soviet bloc and the current travails being experienced in Afghanistan. A comparison of NATO's experience in the Balkans and in the Afghan theatre suggests that the view of a NATO perched permanently at the edge of collapse is problematic and misleading. This is not to defend alliance actions as such but rather to suggest that the narrative of crisis and collapse makes for poor analysis and underestimates NATO's proclivity for adaptation and endurance.  相似文献
