Virtual observatories for space and solar physics research

As soon as the first data became available online over the Internet, it was obvious that different sites holding related datasets should appear to the end user as a single data system, even if the data itself is stored at multiple locations. To achieve this objective in the context of continuing parallel development of multiple data centres, in 2003 several actors in the realm of space plasmas created the international consortium Space Physics Archive Search and Extract (SPASE). Since 2005 US participation in SPASE has been supported by NASA, and early in 2006 NASA funded five new Virtual Observatories to cater for different aspects of solar system plasma science. This paper outlines the current status of the SPASE effort, the opportunities it offers, its specificities with respect to other parts of the astronomical virtual observatory, and the possibilities it offers for space weather.

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.

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.

Airline data for global city network research: reviewing and refining existing approaches

Information on air passenger flows is potentially a prime data source for assessing spatial patterns in the global city network, but previous analyses have been hampered by inadequate and/or partial data. The ensuing analytical deficiencies have reduced the overall value of these analyses, and this paper examines how some of these deficiencies may be rectified. First, we review the rationale for using airline data to analyse the global city network. Second, we assess the data problems encountered in previous research. Third, we elaborate on the construction of datasets that may circumvent some of these problems. The proposed refinements include the omission of the hub function of major airports and ways to extract relevant business flows from the data.

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.

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.

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.

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.

China’s container-related dynamics, 1990–2005

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.

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.

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.

Government and urban management in the 20th century: policies,contradictions, and weaknesses of the New Right

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.

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.

Consideration of natural hazards in the design and risk management of industrial facilities

Recent chemical accidents precipitated by natural disasters have prompted governments in the United States, Japan, and Europe, among other countries, to re-evaluate current practices in the design and risk management of industrial facilities. This paper presents an overview of natural hazard design considerations and external events risk management requirements in the industrial sector, with particular emphasis on industrial practices in the United States, Japan, and Europe. The analysis shows that although regulations exist to ensure industrial plant structures are built to resist natural hazards (up to the design level), there are few laws to address the performance of non-structural elements and safety and emergency response measures during a natural disaster. Laws usually also refer to natural hazards only indirectly, and provisions to prevent or respond to simultaneous disasters from single or multiple sources concurrent with the natural disaster are usually not present.

Ethnic coexistence in a pluralistic campus environment

In Malaysia, ethnic segregation seems to have grown more and more pronounced at all levels of education, which may have in the main contributed to increasing occupational segregation by ethnicity when the graduates left to join the job market. Such trends may be disturbing given the effort the country has put in to promote interethnic understanding and reduce interethnic economic disparity since 1970. By critically investigating the dynamics of ethnic coexistence in the microcosm of the university campus environment, this paper provides statistical evidence to show how far the country has progressed in terms of ethnic relations since the watershed events of May 13, 1969; to what extent Malaysian multiethnic society is different now compared to the unmistakable racial “corporateness” and interethnic “separateness” that Furnivall observed in his classic study of 1948; and in what ways ethnic relations have been reshaped by three decades of affirmative action policies and the form of ethnic democracy adapted for this unique society.

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.

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.

Kansas energy,environment, and conservation: a geological overview

The State of Kansas, as an energy-producing and agriculture-based state, faces problems in production of natural resources and potential pollution from their production. To coordinate information on the exploration, production, and use of coal, nuclear, petroleum, natural gas, hydro, wind, geothermal, coalbed methane, biofuel, solar, and other energy resources, the Kansas Energy Council and the University of Kansas Energy Research Center were created. Water, surface and subsurface, is the other important and maybe the most important natural resource in the welfare of the state. To ease the problems of contamination, situations are monitored by regulatory agencies: the Kansas Corporation Commission, Kansas Department of Health and Environment, and Division of Water Resources of the Kansas Department of Agriculture. The Kansas Geological Survey (KGS) at the University of Kansas serves as the archive for energy and natural resource data and conducts research pertinent to the exploration and exploitation of mineral resources, including energy and water. The Kansas Energy Research Center coordinates and supports energy activities. The Kansas Water Office and the staff for the Kansas Water Authority are charged with water planning and preparing reports on water problems and possible solutions. The cost of preserving the environment in a relatively pristine state really is of no concern considering the possible consequences; living conditions should be preserved to assure future generations, a suitable, sustainable, stable environment. With all the dire predictions for the future and energy-producing and pollution problems, Kansas is a model state in this modern industrial age for protecting the environment and is a leader in conservation.

Flood risk management in Central Viet Nam: challenges and potentials

This article explores the impacts of floods on the economy, environment, and society and tries to clarify the rural community’s coping mechanism to flood disasters in Central Viet Nam. It focuses on the social aspects of flood risk perception that shapes the responses to floods. The research findings revealed that flooding is an essential element for a coastal population, whose livelihood depend on productive functions of cyclical floods. The findings also revealed that floods, causing losses and damages, often inhibited economic development. The surveyed communities appeared to have evolved coping mechanisms to reduce the negative impacts of the floods, yet these coping mechanisms are under pressure due to environmental degradation. Integrated flood risk management is considered as a suitable paradigm for coping with flood disasters.

Indigenous knowledge for natural resource management: a comparative study of Māori in New Zealand and Dusun in Brunei Darussalam

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.
