    A symbolic method to analyse patterns in plant structure whose organogenesis is driven by a multitype branching process

    International audienceFormal grammars like L-systems have long been used to describe plant growth dynamics. In this article, they are used for a new purpose. The aim is to build a symbolic method derived from computer science that enables the computation of the distribution associated to the number of complex structures in plants whose organogenesis is driven by a multitype branching process. To that purpose, a new combinatorial framework is set in which plant structure is coded by a Dyck word. Moreover, the organogenesis is represented by stochastic F0L-systems. By doing so, the problem is equivalent to determining the distribution of patterns in random words generated by stochastic F0L-system. This method leads directly to numerous applications like parametric identication for plant growth model

    Consciosusness in Cognitive Architectures. A Principled Analysis of RCS, Soar and ACT-R

    This report analyses the aplicability of the principles of consciousness developed in the ASys project to three of the most relevant cognitive architectures. This is done in relation to their aplicability to build integrated control systems and studying their support for general mechanisms of real-time consciousness.\ud To analyse these architectures the ASys Framework is employed. This is a conceptual framework based on an extension for cognitive autonomous systems of the General Systems Theory (GST).\ud A general qualitative evaluation criteria for cognitive architectures is established based upon: a) requirements for a cognitive architecture, b) the theoretical framework based on the GST and c) core design principles for integrated cognitive conscious control systems

    From Models to Simulations

    This book analyses the impact computerization has had on contemporary science and explains the origins, technical nature and epistemological consequences of the current decisive interplay between technology and science: an intertwining of formalism, computation, data acquisition, data and visualization and how these factors have led to the spread of simulation models since the 1950s. Using historical, comparative and interpretative case studies from a range of disciplines, with a particular emphasis on the case of plant studies, the author shows how and why computers, data treatment devices and programming languages have occasioned a gradual but irresistible and massive shift from mathematical models to computer simulations

    Accounting for human rights : doxic health and safety practices - the accounting lesson from ICL

    Get PDF
    This paper is concerned with a specific human right - the right to work in a safe environment. It sets out a case for developing a new form of account of health and safety in any organisational setting. It draws upon the theoretical insights of Pierre Bourdieu taking inspiration from his assertion that in order to understand the "logic" of the worlds we live in we need to immerse ourselves into the particularity of an empirical reality. In this case the paper, analyses a preventable industrial disaster which occurred in Glasgow, Scotland which killed nine people and injured 33 others. From this special case of what is possible, the paper unearths the underlying structures of symbolic violence of the UK State, the Health and Safety Executive and capital with respect to health and safety at work. While dealing with one specific country (Scotland), the analysis can be used to question health and safety regimes and other forms of symbolic violence across the globe

    Playground of gender : cross-dressing and self-mutilation as negation of gender identity in Tanja Duckers’s Spielzone (1999)

    Get PDF
    Although it is an outstanding example of writing life as negotiation of gender roles as well as exploration of the body as site of identity constructs, Tanja DĂŒckers’s novel Spielzone, published in 1999, has not yet received the critical attention it deserves. The novel displays an interesting aesthetic technique of representing the milieu of two Berlin districts and their inhabitants, whose identity conflicts can be shown to reflect the state of construction of the urban space before its homogenization through gentrification. Especially with regard to gender identities, DĂŒckers portrays the search for a different lifestyle, which is expressed through a striking focus on aesthetic differentiation and cross-dressing. The protagonists stage masculinity and femininity through a theatrical masquerade, which reveals the construct of gender identities and advocates a postmodern transgender existence. The negotiation of a new identity without binary gender attributions ranges from the negation of traditional role assignments to self-mutilation. In the following paper, DĂŒckers’s text will be analysed as uncanny playground of gender between masquerade and brutal gender embodiment, which nevertheless, with all its negations of conventional values, eventually moves near to a return to traditional patterns.peer-reviewe
