We give in this paper indications about the dynamical impact coming from the main sources of perturbation in biological regulatory networks. First, we define the boundary of the interaction graph expressing the regulations between the main elements of the network . Then, we search what changes in the state values on the boundary could cause some changes of states in the core of the system . After, we analyse the role of the mode of updating on the asymptotics of the (...) network, essentially on the occurrence of limit cycles . Finally, we show the influence of some topological changes on the dynamical behaviour of the system. (shrink)

This book seeks to fill a void in contemporary aesthetics scholarship by considering the cognitive features that make the aesthetic and artistic worthy of philosophical study. Aesthetic cognition has been largely abandoned by analytical philosophy, which instead tends to focus its attention on the ‘non-exhibited’ properties of artwork or issues concerning semantic and syntactic structure. The Cognitive Basis of Aesthetics innovatively seeks to correct the marginalization of aesthetics in analytical philosophy by reinterpreting aesthetic cognition through an integration of Ernst Cassirer’s (...) philosophy of symbolic forms with Paul Crowther’s theory of imagination and philosophy of art. This integration has three important outcomes: 1) it explains why the aesthetic and artistic constitute a unique form of knowledge; 2) it shows the role this plays in the formation of aesthetics as a discipline; and 3) it describes why aesthetic cognition is so deeply engaging. This book’s unique theoretical approach engages with important works of visual, conceptual, and digital art, as well as literature, music, and theatre. (shrink)

This Special Issue is dedicated to building a bridge between different disciplines concerned in the investigation of the qualitative dimension of experience and reality. The two main objectives of the Issue can be summarized as follows: 1) to elucidate the need for a revision of categories to account for the qualitative dimension in various disciplines (that include, for example, the cognitive sciences, neurosciences, biology, linguistics, informatics, artificial intelligence, robotics, newly emerging computer technologies) in order to develop an ontology that can (...) better account for the qualitative, dynamic and relational aspects of different domains of reality; 2) to explore the implications of the enactivist view for a relational and ecological account of the qualitative dimensions of life and cognition.

Tratar cuál es el carácter de la relación entre ciencia y tecnología en el complejo mundo de la Ilustración, es lo que plantea este libro. Los historiadores de la ciencia y de la tecnología han venido suponiendo en las últimas décadas que dicha relación se había producido en un único sentido. La presente obra desafía esta visión por simplificadora y replantea la cuestión para ofrecer un análisi más completo de la interacción entre ciencia e industria en este período.

Building a meaningful model of biological regulatory network is usually done by specifying the components and their interactions, by guessing the values of parameters, by comparing the predicted behaviors to the observed ones, and by modifying in a trial-error process both architecture and parameters in order to reach an optimal fitness. We propose here a different approach to construct and analyze biological models avoiding the trial-error part, where structure and dynamics are represented as formal constraints. We apply the method to (...) Hopfield-like networks, a formalism often used in both neural and regulatory networks modeling. The aim is to characterize automatically the set of all models consistent with all the available knowledge. The available knowledge is formalized into formal constraints. The latter are compiled into Boolean formula in conjunctive normal form and then submitted to a Boolean satisfiability solver. This approach allows to formulate a wide range of queries, expressed in a high level language, and possibly integrating formalized intuitions. In order to explore its potential, we use it to find cycles for 3-nodes networks and to determine the flower morphogenesis regulatory network of Arabidopsis thaliana. Applications of this technique are numerous and concern the building of models from data as well as the design of biological networks possessing specified behaviors. (shrink)

El presente trabajo tiene su centro de interés en el ministerio ordenado, bajo la guía del ordenamiento recíproco que LG 10 establece entre sacerdocio común y sacerdocio ministerial. A este respecto se exponen en un primer momento algunos factores de la situación presente donde puede percibirse la repercusión del tema. Y en un segundo momento se ofrece una reflexión teológica sobre dicho ordenamiento, ubicando el ministerio ordenado en el conjunto del sacerdocio común y haciendo valer el alcance de su realidad (...) sacramental en la forma concreta de servir al sacerdocio común.

... explores the limitations of the transnationalist approach to feminism and questions the neoliberal emphasis on individual freedom and consumer choice as the central goals of feminist activism.... All chapters proceed from the belief in the continued usefulness of intersectionality as a valuable category of critical analysis that is particularly necessary at the time when the effects of neoliberal globalization are undermining many familiar categories of critical inquiry.

Globalization is a natural process. It has a number of advantages & disadvantages, causes many questions and problems, which can hardly sometimes be solved by countries independently. These problems can only be solved by the world community. One of these problems is to maintain the concrete communities identity. Is it possible to keep the unique culture of different ethnos, language, traditions in the globalizing world? Or as some researchers consider, there is a tendency to the formation of the so called (...) super ethnos? In such conditions tolerance takes on special significance as a certain means of activity, as social behavior model, as a norm of behavior for each member of the society. Tolerance as a behavior model on one hand should be worked out by a state legislative body, from the other it should be a norm of behavior for each member of the society. The basis of the tolerant behavior is the principle of mutual understanding.It can be considered to be a moral imperative for the resolution of conflict situations. The relevance & importance of tolerance & creating tolerant relations is a characteristic feature of the democratic personality. (shrink)

It can certainly be said that history of science has experienced a large growth in recent decades in Spain. This has occurred despite the generic term ‘history of science’ covering activities of a very varied nature and lacking an intimate relation between each other, in research as well as instruction. At present the number of publications which could fit into the frame of this branch of learning has increased remarkably and commercial publishing houses have opened their editorial lists to the (...) publication of classics as well as to monographs on the history of science. Moreover, new specialized journals on these subjects have become popular and have joined the small number of journals which already had a certain tradition. The number of participants in the periodical congresses of the Sociedad Española de Historia de las Ciencias y de las Técnicas [SEHCYT] has risen and the number of congresses and symposia that have been held in Spain and have assembled Spanish as well as foreign historians has also increased. As another recent promising detail, we could quote the presence of history of science in the curricula of Spanish university programmes, a presence that tends to increase progressively. (shrink)

Review of Ramona Hosu, Poetry, Identity and Ideology – Early Twentieth-Century America (Cluj: Accent, 2010).

The paper analyzes the role of epistemology in contemporary science study. According to the representatives of cultural approach to scientific cognition the latter should be considered regardless of the issues of falsity or truth, which excludes epistemology from the sphere of science investigation. The paper argues, that though the inquiry of science as an aspect of human culture is quite possible, this sort of analysis is insufficient. In order to understand the nature of scientific cognition one has to supplement it (...) by the results of epistemological consideration. (shrink)

This paper sets out to read how gender is produced in changes to the law of rape introduced in the Criminal Justice and Public Order Act 1994 and in critical academic discussions reflecting on these changes. It utilises the work of Judith Butler in order to form an understanding of how the gendered subject is produced in rape law and in academic discussions about rape law. Through Butler's idea of gender performativity,it contends that neither the statute nor the critique of (...) the legal changes (as represented in academic writings) produce any radical `transformation' in rape law. In neither instance does the law or its critique challenge the normative understanding of gender as the cultural formation of `sex'. Rather, both discourses sustain and maintain what Butler calls ``heterosexual hegemony''. As the final section or the postscript of the paper suggests, there are moments in judgements when the identified subject exceeds the marking and exposes the limits of the hegemonic logic. This exposition can serve as an opening in which, as Butler argues, the politics of resistance can create the possibility of an embodied justice. (shrink)
