The illegal plundering of fishing stocks worldwide is masked behind a maze of corporate structures that makes discovery of the beneficiaries of such activity, difficult, if not impossible to identify. This paper outlines the problem of illegal fishing and then develops a multi-layered response to avert the veil of corporate entity being used as a means of preventing domestic States from answering the principal thematic question—who is the true beneficiary of this illegal behaviour, and who should be held responsible.  相似文献

Geography (or geographers) and earth system science   总被引:1,自引:0,他引:1  
Ron Johnston 《Geoforum》2006,37(1):7-11
A response to Pitman’s recent arguments regarding a perceived invasion of geographers’ territory within the academic division of labour by earth system science. Geography is not the grand synthesiser, the only discipline which can explain the big picture, and arrogant claims that it is are counter-productive, both within and outwith the discipline. Geographers should just get on with what they are doing—well.  相似文献

Historical processes of state formation and nation building are crucial for an understanding of the geography of religions and churches in Europe. Each country has developed its own model of state-church relations, giving rise to a ‘bewildering variety’ as Grace Davie aptly remarks. The aim of this paper is to bring some order to this variety by developing a framework for the comparative study of church-state relations based on Stein Rokkan’s famous conceptual map and recent extensions of it to Central and Eastern Europe by John Madeley. According to that framework Europe has been divided into three mono-confessional (Roman Catholic, Lutheran, and Eastern Orthodox) blocs and two multi-confessional culture belts from Northwest to Southeast, and from Northeast to Southeast. This historical pattern has been challenged by secularisation, which started with the Enlightenment and the French Revolution (Western Europe) and the Russian Revolution (Eastern Europe until the velvet revolutions of 1989/1991) and then became widespread after the ‘cultural revolutions’ of the 1960s. A second challenge has to do with globalisation and its consequences, such as massive immigration and the rise of immigrant religions, and in general deterritorialisation, which means the disembeddedness of religion from its national territory. A third challenge concerns reterritorialisation at other (supranational, regional, transnational, and local) scales, of which the new territorial order of the European Union seems to be the most important. Finally, this paper serves as an introduction to the case studies on church-state relations in this special issue.  相似文献

Assessment of sand encroachment in Kuwait using Geographical Information System (GIS) technology has been formulated as a Multi-Criteria Decision Making problem. The Delphi method and Analytical Hierarchy Process were adopted as evaluating techniques, in which experts’ judgments were analyzed for objectively estimating and weighting control factors. Seven triggering factors, depicted in the form of maps, were identified and ordered according to their priority. These factors are (1) wind energy; (2) surface sediment; (3) vegetation density; (4) land use; (5) drainage density; (6) topographic change and (7) vegetation type. The factor maps were digitized, converted to raster data and overlaid to determine their possible spatial relationships. Applying a susceptibility model, a map of sand encroachment susceptibility in Kuwait was developed. The map showed that the areas of very high and high sand encroachment susceptibility are located within the main corridor of sand pathway that coincides with the northwesterly dominant wind direction.  相似文献

The Netherlands is part of the historic Northwest-Southeast multi-confessional culture belt according to the comparative framework of church-state relations in Europe as recently developed by Madeley on the basis of Rokkan’s conceptual map. The aim of this paper is to describe the development of the church-state relations in the Netherlands within this historic framework of state-formation and nation-building, and to interpret recent challenges of its historic state-church model, such as secularisation, the rise of immigrant religions, and general ‘de- and re-territorialisation’ tendencies. The Netherlands developed from a relatively very tolerant polity dominated by the Calvinist Church to a ‘pillarised’ society, in which the Rome-Reformation divide (which also had a strong geographical dimension) was institutionalised in the political system. After the 1960s, very strong secularisation put this ‘pillarised’ system under severe pressure, but the remnants of this system offered a favourable opportunity structure for religious newcomers (Muslims in particular), who could establish their mosques and Muslim schools relatively easily. However, while the main Protestant churches, and even Catholic and Protestant political parties have merged, failing integration of these newcomers in Dutch society and terrorist attacks at the global level as well as in the Netherlands encouraged a new divide between Muslims and non-Muslims. The metropolitan areas in particular became the scene of this new divide.  相似文献

Nigel Thrift 《Geoforum》2002,33(3):291-298
This paper is an attempt to assess the current state and future prospects of Geography especially but not only in Britain. It is quasi-polemical and should be read in that spirit. The paper looks first at the notable successes of physical and human geography. It then considers how these successes are being buttressed by current events taking place in the world. Next, the paper considers the main problems that beset geography. Finally, however, the paper ends on another positive note by considering some of the exciting new developments that are now taking place in the discipline which will allow it to relate to more of the many worlds that make up geography's vocation.  相似文献

In our study, 48 U.S. departments that grant geography PhDs are compared along four measures of academic productivity. Using 1980–1994 as the base period, research productivity of faculty was assessed by counting book titles, as well as authorships in 77 journals. Teaching productivity was determined by placement of PhDs in graduate programs of geography in North America, and by a weighted index of teaching outcomes. Data were summed for departments, but are reported primarily as productivity per person (per FTE count). The results point to a wide variety of departmental profiles, from those departments that appear to emphasize teaching outcomes to those that are more productive in book publishing and journal authorship, with several exhibiting a balance between teaching and research.  相似文献

The geographic distribution of formal and informal names is considered. Given names are variable and bearers may identify themselves with one name form or another (e.g., William, Will, Billy, Bill, W. T., “Skip”). The form of name chosen by state legislators was classified as formal or informal and the proportions of each were plotted by state. Three regions are identified by their relative use of name formality: the Northeast, where formal names are the rule, the South, centering on Arkansas, where informal names are common, and the West, also characterized by informal names. The West is divided between the Mountain and Pacific states, with large numbers of informal names and the states which they surround, which tend toward formal names. Some states, especially those of the Midwest, do not participate in this process. Indiana and South Carolina are exceptions to the general patterns. Informal names presume to create solidarity between legislators and voters. The South and West are apparently less formal than the Northeast in general, also in name usage.  相似文献
