Geographers show keen interest in projected images employed in tourism as these images both reflect the ideas of the image
producers and influence tourists’ perceptions and (spatial) behaviour. This article focuses on intentional and unintentional
projected images of the Netherlands. The former is especially selective: it relies on stereotypes and presents Holland. The
unintentional projected image created in four travel guides is less stereotyped. While the focus is still on Holland, other
areas of the country are presented as well. Both intentional and unintentional projected images rely on ’othering’ and ’alterity’
to make the Netherlands a unique destination and to offer the tourists a trip that is far from everyday life. However travel
guides use ’alterity’ in different ways and at different levels of scale to create a regional geography of the Netherlands
as well.

A vulnerability index for the Fire Service in the UK has been designed to identify vulnerable locations during episodes of
severe floods. Taking recent case studies with the UK Fire Service, the patterns of vulnerability, in terms of demand on time
and resources, can be explained by investigating the environmental causes and their interaction with the adaptive capacity
of the response agencies.

Knowledge Representation (KR) originated as a discipline within Artificial Intelligence, and is concerned with the representation
of knowledge in symbolic form so that it can be stored and manipulated on a computer. This article surveys that part of KR
that is concerned with the representation of space and time, with particular reference to the use of such representations
in geographical information science.

SPIDR (Space Physics Interactive Data Resource) is a standard data source for solar-terrestrial physics, functioning within
the framework of the ICSU World Data Centers. It is a distributed database and application server network, built to select,
visualize and model historical space weather data distributed across the Internet. SPIDR can work as a fully-functional web-application
(portal) or as a grid of web-services, providing functions for other applications to access its data holdings.

Since 1988, more than 20 US military bases have been redesignated as national wildlife refuges. In order to understand the
processes of these military-to-wildlife (M2W) conversions and their implications, I examine three logics that help to produce
these particular changes: Biodiversity, Brownfields, and Serendipity. These logics contribute to a broader discourse of ecological
militarization that frames military practices as compatible with and contributing to environmental protection. I focus on
the case of the Rocky Mountain Arsenal, Colorado, USA, to examine how these logics of conversion are mobilized into practice,
and what such changes mean as they bring militarism and environmental conservation together in reconfigured spaces.

Melt inclusion formation mechanisms and compositional effects in high-An feldspar and high-Fo olivine in anhydrous mafic silicate liquids 总被引:1,自引:1,他引:0
Important aspects of melt inclusion formation and potential compositions effects have been addressed through a series of experiments using anorthite/fosterite saturated anhydrous mafic liquids. Experimental charges were cooled from 1,300 to 1,230 and 1,210°C at rates of 1–10°/min followed by 0–24 h isothermal periods. Hopper and skeletal crystal morphologies with variable degrees of completeness developed during the cooling period. Planar overgrowth of these textures during isothermal periods led to the formation of inclusions, the majority of which formed after 6 h of isothermal run time. We suggest that the change in morphologies is related to a decrease in growth rates and changes in dominant growth mechanisms. In general, inclusion compositions were uniform and similar to the host glass, indicating that with the isothermal times required for most inclusions to form, a boundary layer was not entrapped that could be detected within the limits of our analyses.

This paper describes an application of the geographic information system (GIS) technology to a ground stability assessment
in the karst area of Dzerzhinsk, Russia. In the stability analysis, the groundwater level changes in the karst aquifer could
cause suffosion sinkholes when the gravitational force was greater than the soil strength. The GIS technology was used to
combine various data and to delineate the zones of potential gravitational collapse and suffosion collapse in the area.

Throughout the 20th century, government in the U.S. has gone through significant changes; initially responding to the disorder
of early capitalism, and later, to the economic crisis of the 1970s. This article will explore the changes in the U.S. political
landscape over the last century, as well as the recent rise of neo-liberalism. In addition, with the analysis of the model
laissez-faire municipal government, the City of Houston, the article will illustrate how the basic weaknesses of neoliberalism
at the national level are also evident at the local scale of government.

The aim of this paper is to use an economic framework to derive decision making rules for river basin management with a focus on groundwater resources. Using an example from northern Nigeria, the paper provides an example of how decision making for sustainable water resources management may be facilitated by comparing net benefits and costs across a river basin. It is argued that economic tools can be used to assess the value of water resources in different uses, identify and analyze management scenarios, and provide decision rules for the sustainable use and management of surface and ground water resources in the region.

Predicting environmental conditions to minimise salt damage at the Tower of London: a comparison of two approaches 总被引:1,自引:0,他引:1
Clifford A. Price 《Environmental Geology》2007,52(2):369-374
The paper compares the results of two studies of salt damage at the Wakefield Tower, Tower of London. The first, in 1993,
was based on semi-quantitative salt analysis and hygroscopicity measurements. The second was based on quantitative analysis
and a thermodynamic model, ECOS. Both studies aimed to predict environmental conditions that would minimise salt damage to
the interior stonework. Their predictions are markedly different, and this paper examines the reasons for the differences.
It is shown that hygroscopicity alone is not a reliable indicator of crystallisation from mixed salt solutions.

Land tenure rights reflect the deeper structures of society, particularly gender distinctions in relation to land. Considering
the structural differences between patrilineal and matrilineal customary tenure systems in East Timor are understudied, this
paper explores men and women’s experiences in accessing land under such arrangements. The comparative analysis of two patrilineal
with one matrilineal land tenure systems in Ainaro and Manufahi districts suggests a significant degree of flexibility within
both systems with respect to the norms of gendered inheritance. Therefore, the binary constructs of ‘patrilineal’ and ‘matrilineal’
societies are limiting. Both men and women in these communities may acquire land rights under different circumstances, mainly
through negotiations with their parents or hamlet chief. Daughters in the patrilineal communities could inherit family land
upon their parents’ death and sons in the matrilineal community could gain land by cultivating and maintaining unclaimed customary
land. Empirical evidence show that inheritance principally determines usufruct rights to land, but marriage exchange practices
complicates a deeper understanding of traditional East Timorese land rights.

Ostensibly, subtitles in films serve as linguistic approximations of meaning. Expectedly then, much of the debate surrounding
subtitling has been concerned with representational accuracy, fidelity and authenticity. In this article I argue that by encountering
subtitles as affective bodily expressions, as opposed to approximate representations of pre-existent meanings or intentions,
filmic experiences may be(come) transformed and differently transformational. As a result, meaning and accuracy in subtitles
as superimposed signifiers or static representations become secondary to subtitles as spatially affective- and expressive-movements
intimately part of filmic scapes. The creative use of subtitling in Bekmambetov’s Russian language film Night Watch (Nochnoy dozor; 2006 [2004]) is discussed.

The advent of the Virtual Observatory has begun an evolution in the space physics data environment. A number of nascent and
discipline specific Virtual Observatories have started to emerge with an emphasis on data search and retrieval. As this new
data environment takes shape an emphasis will be placed on interdisciplinary communication in attempts to address large scale
and global problems. To this end we formulate the development of a query language to facilitate Virtual Observatory to Virtual
Observatory communication. Furthermore, we outline the goals of such a language, how it would work and how existing community
efforts can be leveraged to speed the development of this query language.

This study seeks to gauge how far China’s container-related dynamics between 1990 and 2005 fit into the wider perspective
about transport and development within developing countries. In particular, attention is focussed on the role of specific
modes to determine the extent of the penetration of containers within China. Before addressing these key issues extant models
relating to an understanding of port and transport evolution in less-developed countries are recalled, synthesized and used
as a base upon which an appropriate review of China’s case can be conducted. Applying them to China’s northern, central and
southern port ranges not only helps assess the efficacy of these models but also highlights the contribution of individual
modes.

An increasingly utilized strategy for expanding conservation in the developing world has been the promotion of protected areas
that supersede national borders. Alternatively known as transfrontier biosphere reserves, transfrontier or transboundary conservation
areas, or Peace Parks, these protected areas are aggressively advanced by conservation agencies for their purported ecological
and economic benefits. This article provides a comparative assessment of two case studies to understand the various impacts
of transboundary conservation. The Great Limpopo Transfrontier Park, which unites protected areas in South Africa, Mozambique
and Zimbabwe, is contrasted with efforts to protect jaguars along the United States–Mexico border. We argue that while these
cases are promising for the purposes of biodiversity protection, they demonstrate that transboundary conservation can minimize
political context, contributes to the hegemony of international conservation agendas, and remains closely linked to economic
neoliberalism and decentralization in the developing world.

Contract farmers in central Honduras have been producers of Asian vegetables for American markets since 1989. Contract farming
holds the potential to provide benefits to small farmers who would otherwise be unable to access export markets but production
relations between firms and farmers are often asymmetric and can be exploitative. Poor communication and legacies of mistrust
between commodity agriculture and small farmers lead to ambiguities in the contracting system that are misinterpreted by both
firms and farmers, creating social tensions between contracting parties. This article will consider how farmers’ navigation
of the contracting system and competition between export firms has led to changes in the system. Through competition for a
limited pool of outgrowers, firms adjust their policies in favor of farmers without explicit attempts of labor organization
on the part of the farmers.

Indigenous people often exclusively depend on the natural resources available within the ecosystems where they live, and commonly
manage their resources sustainably. They have developed, and continue to develop indigenous knowledge systems which encompass
sustainable management of natural resources. This study compares indigenous knowledge of natural resource management developed
by two different communities in two different environments—Maori in the temperate environment in New Zealand and Dusun in
the tropical environment in Brunei Darussalam, and comparatively evaluates the role of indigenous knowledge in sustainable
resource management in three categories of knowledge such as spatial and seasonal distribution of natural resources, sustainable
harvesting, and habitat management. The comparison reveals that despite the differences in environment and the great geographical
distance between the two communities, there are remarkable similarities between the two knowledge systems in concepts, principles,
strategies and technologies used in natural resource management.

Summary The question of alternative technologies for high-speed Internet access lies at the heart of rural development problems. In
this paper, we focus on one of those technologies, the system combining satellite technologies and Wi-Fi. Based on an empirical
study carried out in three rural areas, we analyze the dynamics of the use and appropriation of that technology by the companies
and organizations participating in the experiment. Considered both from a technical and social standpoint, the technology
‘in use’ appears here in its structuring dimensions.

The irreversible water–rock mass exchanges leading to the production of the Fiume Grande valley (Calabria, Italy) stream waters
and groundwaters, starting from local rainwaters, were simulated through reaction path modeling in reaction progress (stoichiometric)
mode. The simulations assumed bulk dissolution of a phyllitic rock and calcite and precipitation of gibbsite, kaolinite, amorphous
silica, illite, a smectite solid mixture, a hydroxide solid mixture, and a trigonal carbonate solid mixture. The analytical
contents of major and trace elements in stream waters and groundwaters were satisfactorily reproduced. However, further investigations
are necessary to clarify the fate of As in this natural systems.
