Ash and Nerode [2] gave natural definability conditions under which a relation is intrinsically r. e. Here we generalize this to arbitrary levels in Ershov's hierarchy of Δmath image sets, giving conditions under which a relation is intrinsically α-r. e.

We consider the following generalization of the notion of a structure recursive relative to a set X. A relational structure A is said to be a Γ-structure if for each relation symbol R, the interpretation of R in A is ∑math image relative to X, where β = Γ. We show that a certain, fairly obvious, description of classes ∑math image of recursive infinitary formulas has the property that if A is a Γ-structure and S is a further relation on (...) A, then the following are equivalent: For every isomorphism F from A to a Γ-structure, F is ∑math image relative to X, The relation is defined in A by a ∑math image formula with parameters. (shrink)

In recognition memory paradigms, emotional details are often recognised better than neutral ones, but at the cost of memory for peripheral details. We previously provided evidence that, when periph...

Our understanding of how evolution acts on biological networks remains patchy, as is our knowledge of how that action is best identified, modelled and understood. Starting with network structure and the evolution of protein–protein interaction networks, we briefly survey the ways in which network evolution is being addressed in the fields of systems biology, development and ecology. The approaches highlighted demonstrate a movement away from a focus on network topology towards a more integrated view, placing biological properties centre‐stage. We argue (...) that there remains great potential in a closer synergy between evolutionary biology and biological network analysis, although that may require the development of novel approaches and even different analogies for biological networks themselves.

On the basis of both philosophical arguments and the theological perspectives of Eastern Orthodox Christianity, a critique of two beliefs that are common within the mainstream science–theology dialogue is outlined. These relate to critical realism in understanding language usage and to naturalistic perspectives in relation to divine action. While the naturalistic perspectives on the history of the cosmos that are predominant within the dialogue are seen as generally acceptable from an Orthodox perspective, it is argued that they require theological expansion. (...) This expansion suggests an understanding other than the “causal joint” model commonly adopted in relation to “special” divine action. This alternative model renders the distinction between “special” and “general” divine action redundant, and is based on what has been called a “teleological-Christological” understanding of the cosmos, rooted in the fourth gospel's notion of the divine Logos. The relevance of this critique to scholars outside of the Orthodox community is urged. (shrink)

This chapter examines Eastern Orthodox perspectives on natural theology. The discussions cover the classical roots Orthodox understanding of knowledge of God; worship and eschatology; creation and the limits of natural theology; panentheism and the structure of theophany; and science and theology in Orthodoxy.

Science and religion have often been thought to be at loggerheads but much contemporary work in this flourishing interdisciplinary field suggests this is far from the case. The Ashgate Science and Religion Series presents exciting new work to advance interdisciplinary study, research and debate across key themes in science and religion, exploring the philosophical relations between the physical and social sciences on the one hand and religious belief on the other. Contemporary issues in philosophy and theology are debated, as are (...) prevailing cultural assumptions arising from the `post-modernist' distaste for many forms of reasoning. The series enables leading international authors from a range of different disciplinary perspectives to apply the insights of the various sciences, theology and philosophy and look at the relations between the different disciplines and the rational connections that can be made between them. These accessible, stimulating new contributions to key topics across science and religion will appeal particularly to individual academics and researchers, graduates, postgraduates and upper-undergraduate students.

In the appendix of his latest book, Incontinence of the Void, Žižek presents an account of how, according to his dialectical materialism, love can overcome death. This article situates Žižek ’s argument in the context of his ontology and his theory of the subject to explicate how Žižek arrives at this position: one that appears, on the surface, to be inconsistent with a staunch materialist and atheistic stance. Building on Žižek ’s references to Kierkegaard in this appendix, I will furthermore (...) argue that the figure of the Knight of Faith from Kierkegaard’s Fear and Trembling can be as another instantiation of the revolutionary subject of the act. This figure can be said to participate in a type of love that overcomes death insofar as its attachment to objects of desire embodies the acephalous, undead drive that is not reducible to ontic or symbolic structures of reality.
