Abstract
In his renowned article published in 1967, Lynn White Jr argues that a causal relationship exists between Christianity (grounded in the Bible) and the contemporary ecological crisis. ‘Western’ Christianity, insists White, is the world's most anthropocentric religion, and it is this anthropocentrism that underlies human harm of the environment. The ecological crisis, he argues, is a religious crisis. But White also suggests that since the roots of the ecological crisis are largely religious, the remedy must also be (broadly) religious. With White's words in mind, this chapter outlines a strategy for Christian communities to read the Bible in such a way that it might contribute to the emergence of an ecological sensibility that is appropriate to the environmental concerns of climate crisis in the twenty-first century. It then offers a brief ecological reading of Genesis 1 and 2, exploring how such an interpretation might provide faith communities with a foundation for re-conceiving the relationship between God, Earth and humanity. This chapter argues that, set alongside the ever-increasing scientific discoveries that point towards interdependence and the continuity of all life, the Bible has the potential to act as a powerful resource for Christian communities in the ongoing endeavour to alleviate environmental degradation.

Abstract
Purpose – A geologist and sociologist have developed a pair of Earth resource courses to teach geology in global context and critical thinking and negotiation skills. The energy and minerals courses emphasize the physical and geological sciences as well as an understanding of the political, social structural, cultural, economic, and environmental factors that influence resource extraction and use. We are seeking to develop the global citizenship skills students will need to participate in future discussions on Earth resource issues. To this end, active learning approaches involve students in group problem solving and negotiation.
Methodology – For five years we have been developing these courses and regularly assessing the accomplishment of course goals. Focus groups and before/after surveys guide course modifications.
Findings – Though limited, our evidence shows an increased awareness and willingness on the part of our students to engage in discussions searching for solutions to Earth resource issues. Geology students are enthusiastic about the content that goes beyond geology. Non-geology students appreciate knowing more of the science of Earth resources that help thereby providing critical insight and background for their interest in environmental and social problems.
Value of the paper – The L(SC)2 paradigm we have developed can be adopted or adapted to a variety of possible partnerships between the sciences and the social sciences and humanities. Studying Earth resource issues in global context connects the immediate concerns of consumers to the practices and problems of Earth resource extraction and processing around the world to better foster citizen involvement.

Abstract
This preliminary survey begins to probe a few purposes and practices of “Earth System Science” to rethink the ways in which Nature is “taken into account” by this new power/knowledge formation. The workings of “environmentality,” or green governmentality (Luke, 1999c), and the dispositions of environmental accountancy regimes depend increasingly on the development and deployment of such reconceptualized interdisciplinary sciences (Briden & Downing, 2002). These practices have gained much more cohesion as a technoscience network since 2001 Amsterdam Conference on Global Climate Change Open Science. Due to its brevity, this study is neither an exhaustive history nor an extensive sociology of either Earth System Science or the new post-2001 Earth System Science Partnership (ESSP), which acquired new legitimacy during and after this professional-technical congress. Instead this critique reexamines these disciplinary developments to explore the curious condition of their rapid assembly and gradual acceptance as credible technoscience formations. This reevaluation allows one, at the same time, to speculate about the emergent interests hoping to gain hold over such power/knowledge programs for managing security, territory, and population on a planetary scale (Burchell, Gordon, & Miller, 1991; Foucault, 1991c, pp. 87–104).

Abstract
Present concerns for sustainable development have led to a revival of traditional building practices using natural or recycled resources. There is a perception that buildings constructed from such materials are environmentally benign. This perception is questionable, as often no evaluation is undertaken to assess the associated environmental impacts. Rammed earth is one such construction technology that has seen renewed interest in recent years. The energy required to manufacture materials (i.e. embodied energy) is a significant component of the life cycle energy associated with buildings. This paper assesses the embodied energy of rammed earth construction relative to brick veneer and cavity brick construction. Rammed earth was found to have significantly less embodied energy than cavity brick construction (to which it is closer in thermal performance), but was approximately equivalent to brick veneer construction. Topics of further research identified include thermal performance and strategies for reducing the embodied energy of cement used for earth stabilisation.

Abstract
Light, when constructed in terms of the elementary quanta of light, may be viewed in particle‐like or wave‐like terms. The elementary quanta of light, when placed in motion through space/time at a speed of a constancy of c forms a light path through the space or reference frame viewed. The light path formed is curved, as space/time is curved. The curvilinear light path formed is a function of the gravitational potential within the viewed frame of reference. The linear description of this light path, termed the geodesic (Riemannian), does not describe the curvilinear light path, but rather the chord of the curvilinear path described by the inscribed arc. This linear description of the light path is the manner in which we describe the coordinate system involved, and is the same manner in which we determine the “speed of light”. The arc length of the light path, compared to the lesser value as described by the chord length, allows for a displacement to be determined, if both measures are applied to a linear measure. A displacement of linear coordinates then occurs, with this displacement a result of the gravitational potential occurring within the frame viewed. This displacement, derived via observation and predictions of the quantum model, resolves Maxwell as well as Newton. The theory concludes that the Special Theory of Relativity, suitably modified to account for gravitational displacement within one particular frame, derives a precise relative model of gravitation within the special frame. This model satisfies Newton, as the model arrives at an exact description of the three‐body problem.

Abstract
Purpose
The purpose of the paper is to explore the structural feasibility of substituting traditional thick joint mortars with earth slurry mortars modified with varying amounts of sand. Thin jointing of earth blocks would reduce the cost of sustainable earth construction.
Design/methodology/approach
Compressive strength of earth‐block cubes was determined. Flexural strength was measured using the BRE electronic bond wrench, which enables block couplets to be tested quickly and accurately. Three samples of earth block, one from southwest England and two from East Anglia, together with nine examples of earth slurry mortar jointing were studied, including the effect of reinforcing the joint and or the block using hessian.
Findings
The 28‐day cube characteristic compressive strengths were determined for Appley soil, Norfolk lump and Beeston soil, the last with 0 per cent sand, 25 per cent sand and with 25 per cent sand with hessian. The flexural strengths of Appley and Beeston earth slurries were determined, along with Thermalite thin jointed cement and cement mortar for comparison. The Beeston soil flexural strength increased with increasing sand content. Earth slurry with 40 per cent sand and hessian present in the joint gave the greatest strength. It is important to use blocks and slurry mortars of the same soil. Extruded and compressed earth blocks are best suited to slurry jointing.
Originality/value
This work successfully demonstrates the structural feasibility of carefully reducing the thickness of earth mortars when constructing sustainable earth block walling. Characteristic flexural strengths are suggested where the test results were sufficiently consistent, and of a magnitude likely to be useful in design.

Abstract
Purpose
China holds a global monopoly of up to 97 percent for rare earth elements (REEs), which are indispensable for all kinds of twenty-first century high-tech applications. Since China has disrupted its exports and started discriminating between domestic and foreign demand, REEs have become a geostrategic resource. In March 2012, Japan, the USA and the European Union jointly filed a World Trade Organization dispute settlement case against China. The purpose of this paper is to elaborate why China implemented export quotas and tariffs on REEs and how the state is engaged in this sector domestically and abroad.
Design/methodology/approach
The analysis frames China as a “competition state” and connects domestic with foreign economic policy on REEs. It uses data from Chinese official documents and non-Chinese sources.
Findings
Better government control aims to consolidate the sector and lay the foundation for three other goals, namely: the establishment of integrated and innovative Chinese corporations that compete globally; the provision of incentives to attract high-tech foreign direct investment to China; and better environmental protection. China wants to climb the next step of the technological ladder to gain global economic leadership.
Practical implications
Global environmental protection in mining is eased. However, non-Chinese market players can only take advantage of new business opportunities when the prices remain high. Since REEs are of strategic importance, rising political interference and raw materials diplomacy will continue to distort markets and price building.
Originality/value
The paper connects domestic reregulation of China's rare earth sector with foreign policy goals (or “going in” and “going out”) using the competition state approach.

Abstract
Purpose
The purpose of this paper is to define a new methodology for studying interconnected earthing system inside unearthed medium voltage (MV) networks.
Design/methodology/approach
The developed methodology is based on the division of the MV network into simpler sub‐systems and its resolution using a multiport approach.
Findings
The methodology has been applied to various situations giving precious information on the behaviour of the interconnected earthing systems. The comparison between the results of the simulations and measurements done on a really existing network has shown that the methodology is able to provide accurate results.
Research limitations/implications
Some factors can influence the precision of the methodology. Indeed, for a correct simulation of the system it is necessary to know several electrical and geometrical parameters, often obtainable with difficulty.
Practical implications
Utilities are quite interested in this topic. The study of interconnected earthing systems in MV networks with the purpose of identifying safe extended areas named Global Earthing Systems has important management and economic consequences.
Originality/value
The paper presents a new analysis methodology applicable to MV networks that surpasses the limits of the analysis methodology generally applied for the study of the same topic in high voltage networks.
