    © 2014 Routledge (Taylor & Francis)This is an Accepted Manuscript of an article published by Taylor & Francis Group in British Journal of Religious Education on 14/10/2013, available online: http://www.tandfonline.com/10.1080/01416200.2013.848183This article explores the potential for critical and informed engagement with biblical texts to form a key element of the study of Christian perspectives on ethical issues at GCSE and A level. Given the current dominance of philosophical and ethical topics, and weaknesses in the engagement with biblical texts within existing curriculum materials, the article appeals to recent developments in approaches to biblical scholarship, in particular a focus on the history of interpretation and influence, as a means by which the Bible may be fruitfully and critically engaged in modules focused on contemporary religious ethics. The article then presents the topic of environmental stewardship as a test case for the practical application of such a method, outlining two examples – the stewardship of creation (Genesis 1 and 2) and the future of the earth (2 Peter 3) – to demonstrate how a more sophisticated treatment of the Bible as part of ethical enquiry might be achieved

    What is the object of the encapsulation of a process?

    Several theories have been proposed to describe the transition from process to object in mathematical thinking. Yet, what is the nature of this ''object'' produced by the ''encapsulation'' of a process? Here, we outline the development of some of the theories (including Piaget, Dienes, Davis, Greeno, Dubinsky, Sfard, Gray, and Tall) and consider the nature of the mental objects (apparently) produced through encapsulation and their role in the wider development of mathematical thinking. Does the same developmental route occur in geometry as in arithmetic and algebra? Is the same development used in axiomatic mathematics? What is the role played by imagery

    Catalyst for carbon monoxide oxidation

    Get PDF
    A catalyst is disclosed for the combination of CO and O2 to form CO2, which includes a platinum group metal (e.g., platinum); a reducable metal oxide having multiple valence states (e.g., SnO2); and a compound which can bind water to its structure (e.g., silica gel). This catalyst is ideally suited for application to high-powered pulsed, CO2 lasers operating in a sealed or closed-cycle condition

    A method to find quantum noiseless subsystems

    Full text link
    We develop a structure theory for decoherence-free subspaces and noiseless subsystems that applies to arbitrary (not necessarily unital) quantum operations. The theory can be alternatively phrased in terms of the superoperator perspective, or the algebraic noise commutant formalism. As an application, we propose a method for finding all such subspaces and subsystems for arbitrary quantum operations. We suggest that this work brings the fundamental passive technique for error correction in quantum computing an important step closer to practical realization.Comment: 5 pages, to appear in Physical Review Letter

    A chemical sensor based on a photonic-crystal L3 nanocavity defined in a silicon-nitride membrane

    Get PDF
    The application of a silicon-nitride based L3 optical nanocavity as a chemical sensor is explored. It is shown that by adjusting the thickness of an ultra-thin Lumogen Red film deposited onto the nanocavity surface, the fundamental optical mode undergoes a progressive red-shift as the layer-thickness increases, with the cavity being able to detect the presence of a single molecular monolayer. The optical properties of a nanocavity whose surface is coated with a thin layer of a porphyrin-based polymer are also explored. On exposure of the cavity to an acidic-vapour, it is shown that changes in the optical properties of the porphyrin-film (thickness and refractive index) can be detected through a reversible shift in the cavity mode wavelength. Such effects are described using a finite difference time-domain model

    Extrinsic Evidence, Parol Evidence, and the Parol Evidence Rule: A Call for Courts to Use the Reasoning of the Restatements Rather than the Rhetoric of Common Law

    This article is an example of what Professor Richard Epstein would call Contracts small. According to Professor Richard Epstein, \u27Contracts small\u27 relates to contract law at the doctrinal level; it focuses on the rules of contract formation and performance; the everyday \u27stuff of lawyer\u27s law.\u27 This article looks to the Restatement of Contracts (hereafter Restatement ) and the Restatement (Second) of Contracts (hereafter Restatement Second ) for answers to the questions raised by the two problems. The Restatements generally have both been praised and condemned for their focus on doctrinal issues-on what Richard Epstein calls the everyday stuff of lawyer\u27s law. As indicated earlier, the everyday stuff of lawyer\u27s law includes the terms extrinsic evidence, parol evidence,\u27\u27 and parol evidence rule

    Actin and dynamin2 dynamics and interplay during clathrin-mediated endocytosis.

    Get PDF
    Clathrin-mediated endocytosis (CME) involves the recruitment of numerous proteins to sites on the plasma membrane with prescribed timing to mediate specific stages of the process. However, how choreographed recruitment and function of specific proteins during CME is achieved remains unclear. Using genome editing to express fluorescent fusion proteins at native levels and live-cell imaging with single-molecule sensitivity, we explored dynamin2 stoichiometry, dynamics, and functional interdependency with actin. Our quantitative analyses revealed heterogeneity in the timing of the early phase of CME, with transient recruitment of 2-4 molecules of dynamin2. In contrast, considerable regularity characterized the final 20 s of CME, during which ∼26 molecules of dynamin2, sufficient to make one ring around the vesicle neck, were typically recruited. Actin assembly generally preceded dynamin2 recruitment during the late phases of CME, and promoted dynamin recruitment. Collectively, our results demonstrate precise temporal and quantitative regulation of the dynamin2 recruitment influenced by actin polymerization
