We consider a percolationlike phenomenon on a generalization of the Barabási-Albert model, where a modification of the growth dynamics directly allows formation of disconnected clusters. The transition is located with high precision by an original numerical technique based on the comparison of the largest and second largest clusters. A careful investigation focusing on finite size scaling allows us to highlight properties which would hardly be accessible by an analytical solution of cluster growth equations in the stationary limit. Our analysis shows that some critical features of the percolation transition are different from those observed in the case of dilution in fully grown networks. At variance with other models of percolation on growing networks we also find evidence that the order parameter approaches zero as a power of the field p- pc driving the transition, rather than as a stretched exponential. This behavior does not agree with the Berezinskii-Kosterlitz- Thouless scenario found in other similar models. For describing the phase in which a giant cluster develops, a key role is played by the crossover number of nodes Nx ∼ (p- pc) -ζ with ζ 4. This power law behavior and that of other quantities are conjectured on the basis of scaling arguments and numerical evidence. © 2007 The American Physical Society.

The interest in ethical literary criticism which re-emerged in the 1990s is of particular relevance to the field of ecologically oriented literary criticism. Motivated by a concern for the environment and by the question of how to live an environmentally sound life, its basic goal can be defined as creating knowledge that promotes an environmental ethical stance that in turn triggers processes of environmentally benign social and cultural transformation. The claim – made by moral philosophers and literary critics such as Charles Taylor, Martha Nussbaum, Richard Rorty and David Parker – that literary texts can be regarded as a specific mode of moral inquiry because of the imaginative range and formal richness of their language bears a high degree of importance for ecologically oriented literary scholarship. It supports the idea that literary texts which address morally relevant aspects of the human-nature relationship are indispensable sources for a more comprehensive understanding of the human moral experience – more comprehensive in the sense of extending the moral universe towards the inclusion of parts of nonhuman nature or to non-human nature as a whole. Following a brief introduction into key issues of current ethical literary criticism and into the field of environmental ethics, this essay explores New England regionalist texts by Sarah Orne Jewett as sites of inquiry into environmentally relevant moral issues. Jewett's texts were part of the emergence of American environmentalism in the second half of the nineteenth century. They contributed to the environmentalist discourse as it developed in particular in the activities and publications of movements such as the conservation, preservation and humane movements. Analysis of the environmental ethical dimension of her texts reveals that the sources of the contemporary philosophical discipline of environmental ethics can be understood as reaching far back into literary history. ; Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer ...

Par un autre exemple de méthode synthétique, les œuvres de deux poètes irlandais contemporains, Seamus Heaney et daran Carson, sont ici comparées pour ce qui est de la façon dont ils traitent de l'histoire. Au delà du contexte irlandais post-colonial où la littérature se trouve aux prises avec l'histoire et l'historiographie, cette étude se poursuit par une réflexion plus générale sur les rapports qu'entretient la poésie moderne avec l'idéologie.

This article argues that decades before Sir Walter Scott published his first historical novel, a number of innovative British novels questioned the possibility of rendering historical topics in narrative form. Although Henry Fielding had claimed that the novel should closely resemble historiography, three eighteenth-century British novelists recognized the problems besetting the attempt to provide true stories of the past in different ways. Sarah Fielding tried to get rid of the elevated position of the ‘omniscient’ narrator, rejecting even chronological order in her fictionalised account of the lives of Cleopatra and Octavia. Laurence Sterne parodied not only historiographical ways of arriving at true knowledge of past events in his seminal novel Tristram Shandy, he also demonstrated that the story is the result of the narrator’s use of narrative conventions and of language, and that the gap between the past and the representation of the past cannot be bridged. Maria Edgeworth tried to get rid of the historiographical dilemma by choosing an unreliable narrator as a biographer in her work Castle Rackrent, which is one of those eighteenth-century novels that casts doubt on whether it is possible to tell a true story of the past with those narrative means which Scott would later use to great acclaim.

In characteristic zero, we completely describe the bialgebra structure of A whenever H is either f.d. or cosemisimple and the H-coinvariant part R of A is connected with one-dimensional space of primitive elements.
