'"Military power … remains an instrument with which no state has yet found it possible completely to dispense". So writes Michael Howard in discussing military power and international order'. In a time when abstracts did not precede articles in International Afairs , this was how the then Editor, N. P. MacDonald, introduced Michael Howard's article, 'Military power and international order', originally published in volume 40: 3, July 1964 and reprinted in this anniversary issue. It has been chosen because, 45 years later, it still retains astonishing freshness and relevance. Now in 2009, states, and especially the new US administration, will need to assess the emphasis they put on military means to achieve their foreign policy ends, while attempting to deal effectively with, for example, the confects in the Middle East and Afghanistan, and the threat of international terrorism. Michael Howard was not concerned at the same time with terrorism, or transnational actors, but there remain enduring lessons in his 1964 article about the role of the military instrument to advance states' interests.  相似文献

Historians, like politicians, need to find a language and frame of reference to connect with their audience or readership. In the current US presidential campaign the candidates, Senators John McCain and Barack Obama, are offering the voters a bridge between the troubled past and a more hopeful future. The works under consideration in this review article employ a similar method. All the authors share the widely held view of the broad shape of US foreign relations since the Second World War, in particular the ideological struggle with the Soviet Union known as the Cold War followed by the more amorphous attempt to maintain American primacy, which has characterized the last two decades. Throughout this longer period the processes and goals of US foreign policy have been controversial: there has not, of course, been complete consensus. One topic which was and remains debated is the role and value of individuals, either high‐level politicians or senior diplomats, in the conduct of foreign policy. Another area of debate, often fierce argument, is the impact of domestic forces upon policy‐making. In the present case the leading example is provided by the amalgam of influences which determine US policy towards that nexus of competing interests often optimistically short‐handed as the Arab–Israeli peace process. One link between these two topics is the role of the US in multilateral bodies; and American actions within the United Nations and towards other international organizations are also examined. These and other related issues are contextualized geographically through an examination of American policies in the Greater Middle East, in particular the predominantly Muslim states which stretch eastwards from Egypt to India. While not providing a partisan political programme for the incoming president to follow, the collective message of these texts offers guidelines, even injunctions for the future conduct of US foreign policy.  相似文献

We consider the history of woodland clearing in central western New South Wales, Australia, which has led to the present highly cleared and fragmented landscape. A combined approach is used examining available historical land‐use data and using regression analysis to relate the pattern of cleared and wooded areas in the recent landscape to environmental variables, taking into account the contagious nature of clearing. We also ask whether it would be possible to apply a simple simulation modelling approach to reconstruct a credible historical sequence of clearing in the study area. The historical data indicate that annual clearing rates have varied substantially in the study area and selective tree removal (ringbarking and thinning) has been common. These findings make it unlikely that a simple simulation approach would replicate the spatial and temporal sequence of woodland loss. Our regression results show that clearing patterns can be related to environmental variables, particularly annual rainfall and estimated pre‐European vegetation type, but that patterns are dominated by contagion.  相似文献

The expansive use of armed unmanned combat aerial vehicles (UCAV), or ‘drones’, by the United States over the past decade has occurred within a particular strategic context characterized by irregular warfare operations in permissive environments. Ongoing strategic, ethical and moral debates regarding specific uses of drones may well be overtaken by a new generation of armed combat drones able to survive and operate in contested airspace with design elements such as stealth and greater levels of machine autonomy. These design parameters, and the likely strategic context within which second generation UCAVs will be deployed, suggest a fundamentally different set of missions from those performed by the current generation of drones. The most beneficial characteristic of current unmanned systems has been the ability to combine persistent surveillance with the delivery of small precision‐guided munitions. With a shift to more contested environments, this type of armed surveillance mission may become less practical and second generation UCAVs will instead focus on high intensity warfare operations. These new systems may have significant implications for deterrence, force doctrine and the conduct of warfare.  相似文献

This article engages with the recent geographical literature on policy mobilities in order to examine how the World Bank mobilizes climate change adaptation 'best practices'. Drawing from the relational case study of the Kiribati Adaptation Project and the Community Resilience to Climate Change and Disaster Risk in Solomon Islands Project, the article explores the complex and intensive work required for mobilizing lessons and practices. The analytical work required in building the Kiribati Adaptation Project as a World Bank success story and policy model worthy of replication in new sites is demonstrated. However, heeding calls within the policy mobilities literature to avoid fetishizing mobility and attending to the contradictions between global flows and local institutional specificity, the article finds limited evidence of replication in noted sites of emulation. Instead, there is compulsive citation, publication, and circulation of experiences and successes within the World Bank, which operates to build internal and external legitimacy.  相似文献

The recent introduction of standardised achievement tests in several provinces has created an opportunity for Canadian geographers to contribute to public and theoretical debates. Geographers are well‐equipped to comprehend and analyse the effects that neighbourhoods have upon pupil achievement. Independent of family background and school funding, such effects may be stronger in education than in other fields, such as voting behaviour and health research, but they have been ignored in recent public debates. They should be considered if informed judgements are to be made about whether specific teachers, schools, and boards are doing an adequate job. Analysis of the Ontario Grade 3 test results for 1997 in public schools in the City of Toronto and in Hamilton‐Wentworth indicate that social class had a greater effect on pupil achievement than language background. Differences in the determinants of achievement between these two urban centres may be attributable to local variations in occupational structure and residential patterns. L'introduction récente en éducation des tests de compêtences standardisés, dans plusieurs provinces, offre aux géographes canadiens l'occasion de contribuer aux débats publics et théoriques. Les géographes sont bien placés pour comprendre et analyser les effets de quartier sur le rendement scolaire des élèves. Indépendamment du milieu socioculturel et du financement scolaire, ces effets ont peut être plus d'impact en éducation que dans les domaines tels que le comportement électoral et la recherche dans le milieu de la santé, cependant, ils demeurent à l'écart des débats publics. Ces éléments doivent être considérés si l'on prétend juger en connaissance de cause l'efficacité et le rendement des écoles, le corps enseignant et les conseils scolaires. L'analyse des résultats d'examens de l'Ontario en 1997, pour les élèves des écoles publiques de la troisième année des villes de Toronto et Hamilton‐Wentworth, démontre que la réussite scolaire est plus liée au niveau socio‐économique qu'à l'origine linguistique. La divergence des facteurs de réussites des deux centres urbains est peut‐être attribuable aux variations des structures d'occupation locales et résidentielles.  相似文献
