Visual methodologies through a feminist lens: South African soap operas and the post-apartheid nation

Using a discussion of South African soap operas, I will place the idea of visuality in a discourse analysis that incorporates a feminist epistemological lens, or an epistemology that integrates reflexivity and an acknowledgment of the dialogic nature of visual media. Through this discussion, I will examine the possibilities that dialogism provides for unpacking and exploring the politics of imperfect translation between the visual and the textual. These methodological interventions, I argue, will help enrich discussions of the visual’s role in the contested realm of geographic imaginations and move beyond the distanced position of the masculine gaze.

Beyond the Anglo-American hegemony in human geography: a European perspective

Over the past five years or so, Anglo-American hegemony in human geography has been widely debated. This debate has highlighted the obstacles put in the way of the building of a more international geographical discipline. In this paper, we reflect on the possibilities and also the limitations of Europe as a context for the experimentation with a more cross-national discipline. In doing so, we notice on the one hand the increasing attention towards the Europeanisation of human geography, particularly at an institutional level, but on the other hand we also notice the lack of some basic forms and tools of communication and exchange that might facilitate the mobilisation of scholars around the ‘European project’. The paper tries to offer a contribution to this issue by discussing the ways in which a European journal of human geography might be conceived and also concretely organised. In this respect the paper takes into account issues of language, access to scientific knowledge and recognition of cultural and academic diversities.

Logics of change for military-to-wildlife conversions in the United States

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.

Spatial and temporal knowledge representation

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.

Mapping flood pressure points: assessing vulnerability of the UK Fire Service to flooding

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.

Space Physics Interactive Data Resource—SPIDR

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.

Post-Bam earthquake: recovery and reconstruction

This paper gives a brief explanation of the earthquake in Bam. It also reports on the rescue and relief operations, including the construction of emergency shelters and temporary housing, and on the country’s plan for the reconstruction of the city, which includes debris removal, the rebuilding of rural and urban residential and commercial units, the reconstruction of state and public buildings and public facilities such as schools, rural and urban water aqueducts and grids, the construction of a sewage system, power network and telecommunication system, the provision of water to orchards and farmlands, the renovation of industries and the revival of the cultural heritage, particularly the historical Bam citadel, among others. We also report briefly on the effect of the Bam earthquake on the Iran Earthquake Risk Reduction Strategy and actions.

Use of reaction path modeling to predict the chemistry of stream water and groundwater: a case study from the Fiume Grande valley (Calabria,Italy)

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.

Melt inclusion formation mechanisms and compositional effects in high-An feldspar and high-Fo olivine in anhydrous mafic silicate liquids

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.

Beating words to life: subtitles,assemblage(s)capes,expression

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.

Assessment of suffosion-related hazards in karst areas using GIS technology

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.

Temporary labour migration and sustainable post-conflict return in Sierra Leone

Economic and social development indicators suggest that the small West African state of Sierra Leone is among the poorest countries in the world. Sierra Leone’s economy and quality of life deteriorated rapidly during a decade of political instability and civil war in the 1990s, when many people fled their homes and abandoned their livelihoods due to the rebel insurgency. This paper examines the post-war reconstruction scenario in Sierra Leone and presents recent evidence from two rural communities in the Eastern Province that were badly affected by the conflict. The paper considers the links between the farming and diamond mining sectors, which, despite severe dislocation during the conflict period, have proved to be remarkably resilient. It is argued that seasonal labour mobility associated with this dual economy has not only continued to be a key ingredient in sustaining livelihood portfolios, but is actually an essential pre-condition for the creation of an enabling environment for sustainable post-conflict return.

Evaluating the influence of mixture composition on the kinetics of salt damage in wall paintings using time lapse video imaging with direct data annotation

This paper presents an examination of the timescale of phase transition behaviour of a series of salts known to cause damage to wall paintings and other cultural property. The rate of deliquescence and crystallisation of single salts (nitromagnesite and halite) under different RH regimes, and the extent to which this was affected when mixed with other salts (niter, nitratite and gypsum), was investigated. The study was conducted using simple conventional techniques (mass measurements over time) and also using an innovative new method: timelapse video imaging with online data annotation. The results demonstrate the synergy gained from combining video imaging with environmental data in reference to time in the study of salt phase changes: where it revealed new information concerning the kinetics of deliquescence and crystallisation. The implications of these results for the implementation of environmental control measures within historic buildings are discussed.

Peace Parks and jaguar trails: transboundary conservation in a globalizing world

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.

The role of economic analysis in groundwater management in semi-arid regions: the case of Nigeria

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.

Political ecology of groundwater: the contrasting case of water-abundant West Bengal and water-scarce Gujarat, India

Three apparently disparate themes (groundwater, farmers and politics) interweave in this account of how groundwater-related policies in India have very little to do with the scarcity, depletion or quality of groundwater, and more to do with rural politics manifested, among other things, in terms of the presence or absence of farmer lobbies. Examples from two states of India, the water-abundant state of West Bengal and water-scarce state of Gujarat, were investigated using readily available data, analysis of the literature, interviews and fieldwork. In the case of West Bengal, although there is no pressing groundwater crisis, the government of West Bengal (GOWB) was able to successfully implement strict groundwater regulations along with a drastic increase in electricity tariff. More importantly, GOWB was able to implement these without any form of visible farmer protest, though these measures negatively affected farmer incomes. On the other hand, in Gujarat, where there is a real and grave groundwater crisis, the government of Gujarat has neither been able to implement strict groundwater regulations, nor has it been able to increase electricity tariff substantially. Thus, through the lens of ‘political ecology’ the contrasting case of these two Indian states is explained.

Predicting environmental conditions to minimise salt damage at the Tower of London: a comparison of two approaches

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.

The production relations of contract farming in Honduras

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.

Unidata’s Common Data Model mapping to the ISO 19123 Data Model

Access to real-time distributed Earth and Space Science (ESS) information is essential for enabling critical Decision Support Systems (DSS). Thus, data model interoperability between the ESS and DSS communities is a decisive achievement for enabling cyber-infrastructure which aims to serve important societal benefit areas. The ESS community is characterized by a certain heterogeneity, as far as data models are concerned. Recent spatial data infrastructures implement international standards for the data model in order to achieve interoperability and extensibility. This paper presents well-accepted ESS data models, introducing a unified data model called the Common Data Model (CDM). CDM mapping into the corresponding elements of the international standard coverage data model of ISO 19123 is presented and discussed at the abstract level. The mapping of CDM scientific data types to the ISO coverage model is a first step toward interoperability of data systems. This mapping will provide the abstract framework that can be used to unify subsequent efforts to define appropriate conventions along with explicit agreed-upon encoding forms for each data type. As a valuable case in point, the content mapping rules for CDM grid data are discussed addressing a significant example.

Developing a SPASE Query Language

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.
