The paper discusses earth science training and development in Anglophone Africa, focusing particularly on support to geological survey organisations (GSOs). A distinction is drawn between ‘education’ and ‘training’, the latter used here in a vocational sense. Both are part of a continuing process of career development for earth scientists. First degree level education underpins all subsequent training. The onus for the latter lies with the employers, which need to develop appropriate training programmes for their staff that are compatible with an individual's career development and their own organisations' needs. There are relatively few graduate employees as a percentage of total staff in most African GSOs compared with GSOs elsewhere in the world and the experience of many of the younger scientists may be limited. This, and the often limited resources available, indicate a continuing need for support through development and institutional strengthening programmes. The main approaches to training and development are outlined and examples are given of some applications of these approaches. The training providers include ‘western’ and former Soviet earth science institutions, organisations such as the Association of Geoscientists in Development, and geological societies such as the Geological Society of Africa. The changing emphasis of developing country technical assistance requirements is reviewed. These include a shift from the leader-trainee approach by the provider to an advisory approach. The encouraging emergence of cross-border and regional training and development programmes within Africa is noted.  相似文献

The former United Nations Trust Territory of the Pacific Islands (TTPI) which has been administered by the United States since the end of World War II, has divided itself up into four separate political entities: (1) the Federated States of Micronesia, (2) the Republic of Belau, (3) the Marshall Islands Republic, and (4) the Commonwealth of the Northern Mariana Islands. The first three of these aforementioned entities are freely-associated states with the United States. This is a new form of political arrangement for these areas and it is also new for the United States. All of these areas have a colonial history of domination by Spain, Germany, Japan, and the US, and these colonial powers have all left legacies which the new states have to deal with. There are also a number of natural environmental factors — such as vast distance and the limited store of natural resources - which are constraints that the new states have to face and overcome with the help of the former colonial powers and the rest of the world. Whether or not these new states can be successful in their continued economic and social development at a pace rapid enough to bring sufficient foreign capital, depends on their own energy and also on the nature and quality of the outside assistance.  相似文献

Colonial society in Indonesia during the first forty years of the 20th century faced housing problems for both the European and native populations analogous to those in many Third World countries today. Some colonial cities tried to provide more housing first by annexing more land and so making building sites available and second by supporting the few private building societies which arose. In the mid-1920s housing proponents organized two national housing congresses. One result was the creation of limited liability public housing companies financed jointly by the central and city governments. By 1940 these companies had failed to provide more housing and so improve housing conditions particularly for the urban native population. The poverty of the masses, the shortage of funds, increasing populations, and government priorities which existed in colonial Indonesia are different in scale in Third World countries today and one may wonder if present-day solutions to housing problems will be any more effective.  相似文献

The Second World War marked an epochal change in the relation of geographers to war and the military. The military had long utilised the skills of geographers, but from World War II the relation changed at least in the United States, and the military began less drawing upon existing geographical knowledge than directing a new kind that was increasingly formal, instrumental, and model driven. With the growing importance of the computer, this trend continued even more strongly during the early Cold War period, and was further propelled by the interests of a new, collective assemblage, the military-industrial complex. A cyborg entity, the military-industrial complex enfolded diverse performances, ideas, inanimate objects, people and even academic disciplines into a larger composite, one product of which was a new regime for the production of knowledge. The purposes of the paper are to examine the process by which geography within the United Stated joined this cyborg entity, and the character of the disciplinary knowledge regime that eventuated. The argument is pursued by examining three individuals key to the new disciplinary regime: Waldo Tobler a pioneer of analytical cartography and later GIS whose first job was at RAND on a project to develop an early warning system for nuclear attack; William Garrison who spearheaded the use of economic modelling in studies of transportation that he carried out with his students at the University of Washington Seattle; and Arthur Strahler, a geologist at Columbia University, who through his links to the US Office of Naval Research, funded and directed a set of students who later entered physical geography utterly transforming it to meet the dictates of the new regime.  相似文献

Croatia ranks among those parts of Europe which have taken very high part in all forms of emigration flows in almost all periods of the last few centuries. The emigration from Croatia was caused by different reasons, such as historical, political, national, religious, social and other. It started in the 16th century and has been going on more or less intensively in different historical periods up to now. The first emigrations were caused by Turkish invasion, and those from the later periods came as a result of economical, social and political circumstances in which population of Croatia lived at the time. About 500,000 people had emigrated from Croatia in the period from the end of the century up to World War I. Most of them went to the USA. World War I had made a break in the mass emigration. After the war the emigrant problem came up again, but with some essential changes which were the consequences of the war. World War II stimulated a greatwave of emigration from Croatia. Emigration occurred either voluntarily or involuntarily. For the entire period 1948–1981, statistics show that modern overseas emigration from Croatia totalled roughly 140,000 persons. Finally, we would like to emphasize that the problem of emigration was and is still actual for the Croatian nation, especially in view of the fact that emigration from Croatia did not stop and continues up to this day. As a result today two million and half Croatian immigrants and their descendants live abroad.  相似文献

“五帝时代”是中国史前社会演进的一个重要阶段,然而其历史真实性却一直被质疑,其具体年代也存在较大争议。作者从人地关系视角出发,对这一重大历史问题进行了初步的探讨。首先介绍了历史文献记录“五帝时代”和龙山中晚期考古证据所揭示出类似的“万邦”林立、相互竞争的政治景观及其社会含义,分析了“五帝时代”的可能年代,认为二者在地望、政治景观以及年代等方面都可能存在一致性。基于竞争和冲突与气候变化之间可能存在的成因联系,重建了“五帝时代”的气候背景,发现4.5～4.0 ka BP阶段,即龙山中晚时期为一明显的降温期,且此降温阶段可以与世界其他地区古气候记录对比,进一步证明了该降温期的存在及其广域性分布特征。最后从人地关系的视角,论证了该降温阶段气候变化与“万邦”(酋邦社会)形成之间的成因联系,从一个侧面证明了“五帝时代”存在的历史真实性,同时进一步表明“五帝时代”的年代极有可能相当于龙山时代的中晚期,具体年代为4.5～4.0 ka BP。  相似文献

Military uses of groundwater: a driver of innovation?   总被引：1，自引：0，他引：1  
Military need has been a positive driver to the development of the modern day, and now mature, science of hydrogeology. The important synergy between geology and water supply was appreciated by military men in the mid-nineteenth century but the first real test of this learning only took place in the First World War. German, British and American geologists then mapped water resources and the potential for exploiting groundwater in Belgium and northern France. Technical innovations included deployment of rapid drilling techniques and the promotion of well screens for use in unconsolidated sediments. The mapping techniques were developed further during the Second World War when innovative remote mapping of enemy-occupied territory became an important planning tool to both Allied and German armies. Work in North Africa and other arid and semi-arid terrains promoted insight into the occurrence of groundwater in fresh-water aquifers little replenished by recharge. Mapping of hard rock basement-type environments in the islands of Jersey and Guernsey by German geologists was a concept new to the British Isles. Collectively, these varied initiatives provided part of the foundation for post-Second World War development of modern-day applied hydrogeology.  相似文献

Profound changes in international geopolitics and national policies, as well as global economic restructuring, and technological and communicational development have occurred since Chinatown first emerged. With the rapid pace of globalizing economy, increasing flows of population, commodities, information, and financial resources across the Pacific Rim – particularly in the last two decades – it is imperative that we reexamine the international migration patterns of Chinese population and reconceptualize the resulting Chinese settlement forms in the globalization era. This article attempts to serve such purposes by briefly reviewing the debate centered around historical and contemporary Chinatowns; discussing the impacts of societal and structural factors on Chinese immigration and settlement; presenting a spectrum of contemporary Chinese settlement forms in the United States, and highlighting some key characteristics. The article ends with brief discussion and conclusion sections that summarize some issues in contemporary Chinese community studies.  相似文献

Suburbanization has been a prominent urban process in the United States since the World War II. It has transformed American cities in profound ways in every single aspect of urban development; from population and wealth distributions, through political organization and affiliations, to the built environment. This paper investigates the link between gated communities and the process of suburbanization in the context of socio-economic inequality. It has been shown time and again in the scholarly literature on suburbanization, that suburban neighborhoods in American cities have been traditionally more affluent and less diverse than central cities. The research on gated communities in the US also shows that they are, on average, more affluent compared to other communities in terms of family income and housing values. Are gated communities then simply a new form of suburban communities? Is the gated community in fact a suburban community with the added element of security features? The paper investigates these questions based on segregation and spatial analyses. The research contributes to the long line of studies on suburbanization, gating and the larger issues of urban inequality.  相似文献

This paper explores the operation of the international World Heritage Convention in the national context of the United States. Although an early advocate of the national park idea and among the earliest proponents of the Convention, the US has shown increasing ambivalence towards the World Heritage Program since the mid-1990s. Through in-depth interviews with expert informants and a questionnaire survey of 406 visitors at four US World Heritage Sites, this study considers whether combining national and international conservation designations provides valuable reinforcement of conservation goals, or leads to unnecessary overlap and even challenges to sovereignty. The majority of my expert informants were supportive of the Convention, related to philosophical and practical benefits that they believed to be associated with the World Heritage label, although most identified few tangible influences of the World Heritage Program itself. Several noted hostility to the Program from a nationalist fringe, which fears international involvement in land use decisions. Such concerns were reflected in questionnaire responses, which revealed some distrust of the Convention and misunderstandings of its operation. I conclude that the scalar mismatch of implementing an international convention at the national scale inevitably involves challenges, but that country-specific factors are important in explaining why the Convention has been particularly controversial in the US. Education is integral to addressing these challenges, as well as reengagement with the Program by both the National Park Service and the federal administration. Intangible values associated with World Heritage mean that the Convention still enjoys considerable support in the US, providing a solid foundation for such a reengagement.  相似文献

People have been exploiting the limestone massifs of the Venetian Fore-Alps since prehistory. The fluviokarstic style of the relief and the location of springs were important controls of settlement and land use. Six principal types of exploitation are recognized and overlapped in time: (1) hunting and early farming, Paleolithic to Iron Age, with the first soil erosion; (2) general deforestation for timber, charcoal, and fuel, Roman to early modern; (3) farm enclosure and improvement, with stone clearing, medieval to modern; (4) trench warfare in World War I; (5) quarrying and specialized farming (dairy, poultry, pigs) since 1950; and (6) developmnent of modern summer and winter tourist facilities. Soil erosion effects from many centuries can still be recognized, war damage remains visible and continues to pollute aquifers, and modern pressure on the karst land and water resources is often severe.  相似文献

This paper is an examination of the splintering urbanism argument of the relationship between neo-liberal reforms of infrastructure networks and urban cohesion. Based on an analysis of historical and contemporary processes of infrastructure provision (water, sewerage and power) in colonial/post-colonial Bombay/Mumbai, it questions the assumption of a “modern infrastructure ideal” in the context of developing cities. In Mumbai, the historical analysis reveals the contradictions between this ideal and a hierarchical society. From the outset, access to services (particularly water and sewerage) was highly distorted in favour of the elites, even though utilities networks contributed to urban integration through cross-subsidies within and across sectors, and through the setting up of municipal institutions. Second, ongoing sectoral reforms demonstrate contrasting trends as increased differentiation of services produces both positive – better adaptation to users’ needs – and potentially negative – fragmenting – socio-spatial implications. Third, an understudied potential fragmenting threat also lies in the sectoral approach to reforms as it undermines the existing crosssector subsidies and prevents the articulation of utility reforms with other limiting factors, such as land and transport, which are the main constraints for expanding housing and mobility in the city.  相似文献

When Czechoslovakia was formed after World War I from the remains of the Austro-Hungarian Empire, the national boundaries imposed at the time did not accurately portray the areal extent of some ethnic groups. This was particularly true for the Hungarian minority which was established along the southern border of Slovakia. Because of this boundary arrangement, ethnic and economic divisions have resulted within Czechoslovakia and have continued in the new state of Slovakia. This paper analyzes the contemporary regional extent of the major ethnic groups in Slovakia at the district and commune levels. It also analyzes these ethnic patterns in light of a number of economic characteristics. Methods include mapping and analysis of various statistical tests using 1991 Czechoslovak census data. A strong relationship between Hungarian communes and agricultural employment is shown as well as a connection between employment in industry and Slovak ethnic regions. These findings suggest that the Hungarian minority has experienced a substantial geopolitical shift from the group in power to a peripheral society within Slovakia that continues to exhibit higher levels of agricultural reliance than the majority of ethnic Slovakian regions.  相似文献

In the post-Soviet era, the United States (US) is expected to contribute its military forces and defense resources in the event of need for Regional Conflicts and Operations Other Than War (OOTW). Such contributions may not be forthcoming. The principal reasons for the possible absence to the US contributions to maintain the New World Order is the paucity in the articulation of the US foreign and defense policies. The US public's well known preference for domestic policies, rather than foreign military and related operations, has been reinforced by the absence of the comprehensive explanation by the US political leaders of the US foreign and defense policies to the American people. The US military are preparing military doctrine for the possible engagements in the Regional Conflicts and OOTW, but these efforts are affected by the US well established past military doctrine to fight wars to a clear victory on the battlefield as well as by the absence of clear national military policy. American particulation in the future military operations — Regional Conflicts or OOTW — remains very much in doubt.  相似文献

American pragmatism: Towards a geographical introduction   总被引：1，自引：0，他引：1  
Trevor J. Barnes 《Geoforum》2008,39(4):1542-1554
The purposes of the paper are to provide a historical and thematic review of some of the variants of American philosophical pragmatism (old and new), and to point to its potential relevance for geography. The paper is divided into three sections. The first, discusses the origins of American pragmatism focussing on four figures: John Dewey, Oliver Wendell Holmes, William James, and Charles Sanders Peirce. Following the argument of Louis Menand (2001) in The Metaphysical Club, I will suggest that pragmatism took on its peculiar American character as a response to the deep fissures and wounds caused by that country’s Civil War. That war produced a loss of faith, undermining notions of universal progress and absolute truth. Pragmatism was the reaction. The second section brings pragmatism to the present, by focussing on three connected contemporary American pragmatists: Richard Rorty, Richard Bernstein, and Richard Shusterman. The hallmark of their work, and which justifies treating them as a group, is a willingness to stretch pragmatism: first, by making linkages with other anti-foundational, practice-based philosophical traditions, especially those within Continental European philosophy, and which had been shut out of Anglo-American philosophy after the Second World War by the rise of analytic philosophy; and second, by applying pragmatist ideas to issues like the body and popular culture to which it had never been applied. Finally, in the conclusion the paper reflects on the prospects of tethering pragmatism to the work of human geographers. Given the anti-architectonic impulses of pragmatism, such a project cannot simply be one of holus-bolus transferring pragmatism to geography. A different approach is needed, and which is schematically outlined and briefly illustrated using the idea of place.  相似文献

The World Gay Pride week convened in Rome in July 2000 at the same time the Catholic Church planned on celebrating its Holy Year Jubilee. Thousands of gays came together, and by the end of the week more than 200,000 marched through the streets of Rome's historical centre. This unique event provides an opportunity to examine the causal relationship of the gay movement acquiring a political identity of its own while the city of Rome was trying to assert a `proper' identity for its public spaces. Acting in solidarity for the first time since its formation, the gay movement drew attention to the difficulties in securing unrestricted access to Rome's public spaces. Conservative sectors of society challenged the right to demonstrate, as guaranteed in Italy's Constitution, which resulted in the delay of obtaining the necessary permit. On the one hand, this revealed the existence of sectors of society not yet willing to acknowledge gay rights or even discuss gay issues in public; on the other, it helped make clear that the process for building Rome's identity is governed by a specific political design. In particular, policies for the privatisation of urban space in conjunction with discriminatory planning processes in the city's historical centre, point to tourism as a powerful tool to control urban space. Resisting this spatial marginalization the gay movement has significantly widened the scope of its social and political action in order to contest prevailing practices and trends which are shaping the city.  相似文献

Relations between the United States and Europe have been quite volatile over the past five years. This volatility is not just a product of disagreements over the American invasion of Iraq. It is tied to a set of fundamental challenges to the geopolitical arrangements and understandings that emerged in the wake of World War II. Three challenges were of particular importance: the fall of the Iron Curtain, the Balkan crisis of the 1990s, and the election of a presidential administration in Washington, DC, which adopted a neoconservative geopolitical agenda. The global impacts of this agenda were heightened by the September 11, 2001, attacks on the United States of America. The U.S. response exposed fundamental differences between the U.S. and Europe on the use of international military forces in the “war on terrorism,” the role of NATO, and the U.S. government’s effort to force “regime change” in Iraq. Europe’s reaction to U.S. policy has not been uniform, however. At the governmental level, fundamental differences have emerged among European countries. The United States has sought to highlight those differences, suggesting that the U.S. favors “disaggregation” in Europe, even as it trumpets the virtues of a uniform response to the threat of terrorism. The future trajectory of U.S.-European relations is likely to be shaped by intersections between Europe’s struggles with integration and the U.S.’s evolving global geopolitical posture, which could move in either a hegemonic or a globalist direction.  相似文献

Salt mining induced ground subsidence is a major hazard in the city of Tuzla (Northeastern sector of Bosnia and Herzegovina) and its surroundings since 1950, when solution mining of salt deposits by boreholes began. An analysis of the large (and never before processed) amount of topographical data collected during two periods: from 1956 to the Balkan War, and from 1992 to 2003 has been made. The analysis reveals a cumulative subsidence as high as 12 m during the whole period, causing damage to buildings and infrastructures within an area that includes a large portion of the historical town. Human-induced subsidence, (with rates up to 40 cm/year in the most developed area), has been investigated to recognize the areas affected by the sinking phenomenon and to produce a subsidence hazard. The time series of topographical observations have been enlarged by conducting new surveys in the urban area by modern space-geodesy methodologies, such as static relative GPS (Global Positioning System) and high resolution satellite imageries. The GPS monitoring started in 2004 and detected a decrease in the subsidence rates to 20 cm/year related to the reduction of salt exploitation. There is close correlation between the average subsidence rate and the annual amount of salt extracted.  相似文献

In the face of mounting environmental degradation and persistent poverty over the previous decade, Johannesburg’s World Summit on Sustainable Development (WSSD) of August and September 2002 inherited a number of unmet accords from the 1992 Rio de Janeiro Earth Summit. Consequently, the United Nations Stakeholder Forum Implementation Conference (IC) was convened to integrate civil society stakeholders into global deliberations on sustainable development and to marshal their forces in the implementation of WSSD accords. Given the importance of the IC as the first civil society forum at a major global summit on environment and poverty, intriguing questions emerge as to its effectiveness in achieving civil society objectives. As a first attempt in exploring this topic, we examine three fundamental aspects of the IC. Specifically, we examine the relative “civility” of the IC forum in terms of (a) fidelity of representation of the community of global environment and development stakeholders; (b) autonomy of the IC agenda from state and institutional interests; and (c) interpretations of space and place as reflected in deliberative processes and outcomes. The paper begins with a review of the civil society literature with a particular emphasis on civil society representation in UN meetings since Rio. The paper concludes with a discussion of IC participation at the Johannesburg summit, and considers implications for future civil society participation in global decision-making forums.  相似文献
