The multilinear extension of a cooperative game was introduced by Owen in 1972. In this contribution we study the Lovász extension for cooperative games by using the marginal worth vectors and the dividends. First, we prove a formula for the marginal worth vectors with respect to compatible orderings. Next, we consider the direct market generated by a game. This model of utility function, proposed by Shapley and Shubik in 1969, is the concave biconjugate extension of the game. Then we obtain (...) the following characterization: The utility function of a market game is the Lovász extension of the game if and only if the market game is supermodular. Finally, we present some preliminary problems about the relationship between cooperative games and combinatorial optimization. (shrink)

Dentro de la sociología francesa actual, Gilles Lipovetsky se ha convertido de forma paulatina en uno de los sociólogos con mayor proyección internacional, con sus finos análisis sobre las sociedades postmodernas. En este artículo se plantea una revisión crítica de las principales líneas argumentativas que expone el autor francés. El objetivo es el de reflexionar sobre las limitaciones de su aproximación a los conceptos de postmodernidad, hipermodernidad, y consumo.

Background and objective: Assuming the hypothesis that the general practitioner can and should be a key player in making end-of-life decisions for hospitalised patients, perceptions of GPs’ role assigned to them by hospital doctors in making withdrawal decisions for such patients were surveyed.Design: Questionnaire survey.Setting: Urban and rural areas.Participants: GPs.Results: The response rate was 32.2% , and it was observed that 70.8% of respondents believed that their participation in withdrawal decisions for their hospitalised patients was essential, whereas 42.1% believed that (...) the hospital doctors were sufficiently skilled to make withdrawal decisions without input from the GPs. Most respondents were found to believe that they had the necessary skills and enough time to participate in withdrawal decisions. The last case of treatment withdrawal in hospital for one of their patients was described by 40% of respondents, of whom only 40.0% believed that they had participated actively in the decision process. The major factors in the multivariate analysis were the GP’s strong belief that his or her participation was essential , information on admission of the patient given to the GP by the hospital department , rural practice , visit to the patient dying in hospital and a request by the family to be kept informed about the patient .Conclusion: Strong interest was evinced among GPs regarding end-of-life issues, as well as considerable experience of patients dying at home. As GPs are more closely corrected to patients’ families, they may be a good choice for third-party intervention in making end-of-life decisions for hospitalised patients. (shrink)

This volume consists of fourteen chapters selected from papers presented at the conference 'Ethics, Medicine and Health Care: An Appraisal of the Thought of H. Tristram Engelhardt, Jr.' along with a response to those chapters by Engelhardt and a Foreword by Laurence B. McCullough. The chapters direct primary attention to various aspects of Engelhardt's philosophy of medicine and bioethics as presented in The Foundations of Bioethics and Bioethics and Secular Humanism: The Search for a Common Morality. Among the topics treated (...) are the economics of health care and the medical profession, the libertarian and communitarian aspects of Engelhardt's thought, the moral status of children, abortion, the moral foundations for a health care system, feminism and clinical epistemology, and the relation between secular and religious moralities. In response to the various challenges posed by the authors, Engelhardt considers the implications of the failure of the modern philosophical project, the role of reason in ethics, and the resolution of conflict among communities that do not share the same moral vision. The book will be of interest to professionals in medicine, philosophy, theology, health policy, and law, and to graduate students in those disciplines. (shrink)

This paper presents two formation tracking control strategies for a combined set of single and double integrator agents with an arbitrary undirected communication topology. The first approach is based on the design of distance-based potential functions with interagent collision avoidance using local information about the distance and orientation between agents and the desired trajectory. The second approach adds signed area constraints to the desired formation specification and a control strategy that uses distance as well as area terms is designed to (...) achieve tracking convergence. Numerical simulations show the performance from both control laws. (shrink)

In this article, we present results from a literature review of intrinsic, instrumental, and relational values of nature conducted for the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, as part of the Methodological Assessment of the Diverse Values and Valuations of Nature. We identify the most frequently recurring meanings in the heterogeneous use of different value types and their association with worldviews and other key concepts. From frequent uses, we determine a core meaning for each value type, which is (...) sufficiently inclusive to serve as an umbrella over different understandings in the literature and specific enough to help highlight its difference from the other types of values. Finally, we discuss convergences, overlapping areas, and fuzzy boundaries between different value types to facilitate dialogue, reduce misunderstandings, and improve the methods for valuation of nature's contributions to people, including ecosystem services, to inform policy and direct future research. © 2023 The Author(s).

This thought-provoking book discusses the concept of progress in economics and investigates whether any advance has been made in its different spheres of research. The authors look back at the history, successes and failures of their respective fields and thoroughly examine the notion of progress from an epistemological and methodological perspective. The idea of progress is particularly significant as the authors regard it as an essentially contested concept which can be defined in many ways – theoretically or empirically; locally or (...) globally; or as encouraging or impeding the existence of other research traditions. The authors discuss the idea that for progress to make any sense there must be an accumulation of knowledge built up over time rather than the replacement of ideas by each successive generation. Accordingly, they are not concerned with estimating the price of progress, reminiscing in the past, or assessing what has been lost. Instead they apply the complex mechanisms and machinery of the discipline to sub-fields such as normative economics, monetary economics, trade and location theory, Austrian economics and classical economics to critically assess whether progress has been made in these areas of research. -/- Bringing together authoritative and wide-ranging contributions by leading scholars, this book will challenge and engage those interested in philosophy, economic methodology and the history of economic thought. It will also appeal to economists in general who are interested in the advancement of their profession. (shrink)

Research investigating female gaming is relatively scarce, and past research has demonstrated that men are more likely to be problematic gamers. Few studies have focused on female gamers in community samples, and those that have been published have mainly collected data qualitatively in Europe. There is case study evidence suggesting clinicians are increasingly treating problem female gamers. The aim of this study is threefold: (i) to establish an international female gamer profile, (ii) to determine predictors associated with perceived internet gaming (...) disorder (IGD), and (iii) to identify those who are potentially at risk of developing gaming addiction and its characteristics by applying a quantitative approach. A cross-sectional online survey was applied through international gaming forums recruiting 625 female gamers, assessing sociodemographics, gaming devices used and play genres, and a set of questionnaires on gaming (e.g., problem online gaming [e.g., the nine-item short-form scale to assess IGD: IGDS9-SF], female stereotypes [e.g., sex role stereotyping scale], and psychological symptoms [e.g., Symptom CheckList-27-plus]). Female gamers from all continents reported the use of all videogames, especially popular online games using computers and consoles. The proportion of gamers with potential IGD was one per cent. Regression analyses identified several risk factors for increased scores on the IGDS9-SF, namely having achievement and social motivations, embodied presence and identification with the avatar, hostility and social phobia together with negative body image, playing Multiplayer Online Battle Arena, Massively Multiplayer Online Role-Playing Games, and First-Person-Shooter games. Findings contribute to filling the gap in knowledge on female gaming, to aid in the applicability of problematic gaming measurements in female gamers, especially those who are at risk of problematic gaming. The purpose of this study is to enhance the validity of the current measures to diagnose problem gaming appropriately in both genders. (shrink)

El presente artículo trata de hacer ver que el desencuentro entre la modernidad ilustrada y la religión católica, fue debido a una serie de factores y circunstancias desgraciadas, y no a una incompatibilidad inevitable. Es más, a pesar de los malentendidos y desencuentros, no son pocos los ideales de la modernidad ilustrada que, si profundizamos en ellos, descubriremos su inspiración y raíces cristianas. Es más, guste o no a algunos, el patrimonio espiritual y moral que ha ido configurando la identidad (...) europea ha tenido una de sus más importantes fuentes de inspiración en la tradición judeo-cristiana, sin menoscabar, por supuesto, la herencia griega, el derecho romano, la tradición liberal-ilustrada, y la revolución científica. Especialmente, hemos hecho hincapié en la autoridad moral del sufrimiento de la tradición judeocristiana, como una baza fundamental de cara la defensa de la dignidad humana. Para profundizar en esta compleja problemática hemos tenido en cuenta, entre otros, los análisis de Karl Löwith, Hans Blumenberg, J. Habermas, Benedicto XVI y J.B. Metz. Nuestra conclusión es que no tiene razón el actual secularismo-laicismo excluyente al pretender minusvalorar, o borrar simplemente del mapa, las raíces cristianas de Europa, como portadoras de valores y actitudes, que son tan necesarias ante el relativismo, el nihilismo postmoderno, y la crisis de valores de una sociedad, cada vez más deshumanizada. Frente al euroescepticismo que hoy sobrevuela amenazante, hay que reivindicar el “humanismo socrático-cristiano” como una seña de identidad irrenunciable. Otra cosa es el integrismo religioso, que no acaba de admitir la autonomía de la sociedad civil y del Estado, como presupuesto fundamental de una sana secularidad. Es precisamente en el seno de la sociedad civil donde la institución religiosa tiene derecho a dejar oír su voz, en diálogo respetuoso con las otras voces que en ella se ubican, de cara a consensuar soluciones frente a los graves problemas que nos acucian. Y sólo desde una identidad europea bien asentada, podremos enfrentarnos con el reto de la multiculturalidad al que Europa se ve inevitablemente abocada, en el contexto de la globalización.This article attempts to show, that the disagreement between enlightened modernity and Catholic religion, was due to a number of factors and unfortunate circumstances and not to an unavoidable incompatibility. There is more, despite misunderstandings and disagreements, there are many ideals of enlightened modernity that when we go deeper into them, we discover their Christian inspiration and roots. Even more, like it or not some people, spiritual and moral heritage, which has configured European identity, had Judeo- Christian tradition as one of its sources of inspiration, without underestimating, of course, Greek heritage, Roman law, liberal enlightenment tradition and scientific revolution. We have emphasized, especially, the moral authority of suffering of Judeo-Christian tradition as something basic to defend human dignity. To go deeper into this complex problem, we took into account, among others, the analyses of Karl Löwith, Hans Blumemberg, J. Habermas, Benedit XVI, and J:B: Metz. Our conclusion is that the current exclusive secularism is not right trying to underestimate or eliminate the Christian roots in Europe as carriers of values and attitudes, so necessary against relativism, postmodern nihilism and the crisis of values in a society increasingly dehumanized. Against an Euroscepticism which overflies threatening, we must claim a Socratic-Christian humanism as a sign of indispensable identity. Religious secularismis something different, it does not admit the authority of a civil society and state, as a fundamental prerequisite for a healthy secularity. It is precisely within a civil society where a religious institution has the right to be heard in a respectful dialogue with others voices that are located in there to agree on solutions against the problems we are facing and, only from a well established European identity, we will be able to face the challenge of multiculturalism to which Europe is inevitably doomed in a context of Globalization.

The acquisition and evolution of speech production, discourse and communication can be negatively impacted by brain malformations. We describe, for the first time, a case of developmental dynamic dysphasia (DDD) in a right-handed adolescent boy (subject D) with cortical malformations involving language-eloquent regions (inferior frontal gyrus) in both the left and the right hemispheres. Language evaluation revealed a markedly reduced verbal output affecting phonemic and semantic fluency, phrase and sentence generation and verbal communication in everyday life. Auditory comprehension, repetition, naming, (...) reading and spelling were relatively preserved, but executive function was impaired. Multimodal neuroimaging showed a malformed cerebral cortex with atypical configuration and placement of white matter tracts bilaterally and abnormal callosal fibers. Dichotic listening showed right hemisphere dominance for language and functional magnetic resonance imaging (fMRI) additionally revealed dissociated hemispheric language representation with right frontal activation for phonology and bilateral dominance for semantic processing. Moreover, subject D also had congenital mirror movements (CMM), defined as involuntary movements of one side of the body that mirror intentional movements of the other side. Transcranial magnetic stimulation and fMRI during voluntary unimanual (left and right) hand movements showed bilateral motor cortex recruitment and tractography revealed a lack of decussation of bilateral corticospinal tracts. Genetic testing aimed to detect mutations that disrupt the development of commissural tracts correlating with CMM (e.g., Germline DCC mutations) was negative. Overall, our findings suggest that DDD in subject D resulted from the underdevelopment of the left inferior frontal gyrus with limited capacity for plastic reorganization by its homologous counterpart in the right hemisphere. Corpus callosum anomalies probably contributed to hinder interhemispheric connectivity necessary to compensate language and communication deficits after left frontal involvement. (shrink)

ABSTRACTPolitical actors use metaphor in their speeches in order to frame political issues [Charteris-Black, J.. Politicians and rhetoric: The persuasive power of metaphor. Basingstoke: Palgrave Macmillan]. If they succeed in imposing a particular frame, especially when there is no agreement on the definition of certain political issues, this can become the prevailing way for referring to that issue [Semino, E.. Metaphor in discourse. Cambridge: Cambridge University Press]. In this research, we argue that this was the case for the metaphor of (...) the JOURNEY in the Catalan political conflict during electoral periods. To that end we use Critical Metaphor Analysis [Charteris-Black, J.. Corpus approaches to critical metaphor analysis. Basingstoke: Palgrave Macmillan] to analyse televised campaign ads from the last three elections for the Parliament of Catalonia – from 2010, 2012, and 2015 – in order to identify how political actors’ use metaphors to talk about the Catalan political situation during these years and to verify if JOURNEY metaphor resulted into the dominant narrative. The results show that the political situation has been conceptualized in terms of a ‘process en route,’ although the narratives generated by the political actors that shaped that discourse differ.

George Berkeley's Principles of Human Knowledge is a crucial text in the history of empiricism and in the history of philosophy more generally. Its central and seemingly astonishing claim is that the physical world cannot exist independently of the perceiving mind. The meaning of this claim, the powerful arguments in its favour, and the system in which it is embedded, are explained in a highly lucid and readable fashion and placed in their historical context. Berkeley's philosophy is, in part, a (...) response to the deep tensions and problems in the new philosophy of the early modern period and the reader is offered an account of this intellectual milieu. The book then follows the order and substance of the Principles whilst drawing on materials from Berkeley's other writings. This volume is the ideal introduction to Berkeley's Principles and will be of great interest to historians of philosophy in general. (shrink)

En el presente trabajo se estudian las distintas interpretaciones de la metafísica de Francisco Suárez propuestas en el siglo xx. Éstas se dividen en tres grupos: esencialista, existencialista y objetivista. La interpretación esencialista ha sido mantenida fundamentalmente por autores tomistas, siendo E. Gilson el estudioso más destacado. La interpretación existencialista, con J. Hellín a la cabeza, puede ser analizada como reacción a la esencialista. La interpretación noético-objetivista encuentra su fuente de inspiración en M. Heidegger y su impulso definitivo en los (...) trabajos de J. F. Courtine. Mantendremos, con Gourtine, que el que Suárez no pueda ser encasillado sin palpables aporías ni en las filas del esencialismo ni en las del existencialismo se debe a que inaugura un nuevo ámbito para la metafísica: el ontológico, que se sitúa en un plano intencional, más acá del plano de la efectividad y de la creación en el que se mueve la metafísica medieval.

It may seem strange, in view of the spate of recent literature on the subject, that yet another article should be forthcoming on what is certainly the most familiar, as well as the most vexed, of all Platonic passages. But it is precisely this spate of literature that has impelled me to write. The time seems to have come for an article which, rather than seeking desperately for something new, sets out instead to reaffirm those facts and conclusions that even (...) the most resolutely original of scholars could hardly venture to dispute. This article will therefore be based, not on any of the numerous modern interpretations, but on what Plato himself actually wrote. It will contain a number of tentative suggestions which, to the best of my knowledge, have not been made before. They can, and probably will, be rejected. But its primary purpose remains to restate, whenever possible in Plato's own words, a number of important facts that are at once so simple and so obvious that they seem repeatedly, and especially in recent years, to have been quite forgotten.
