La presencia de Platón y del pensamiento platónico se ha mantenido de manera incesante a lo largo de la historia de la cultura. En esta historia, el siglo XX refleja el rechazo y la aceptación, la recepción, en suma, de un modo inusitado tal vez porque, durante este siglo, la humanidad se vio cara a cara con los infiernos que supo crear: un mundo en ruinas hacía imposible intuir la perfecta quietud de las Formas. La recepción de Platón en el (...) siglo XX bucea en la recepción de Platón en aquel mundo contradictorio: ¿cómo se integra su pensamiento fundacionalmente metafísico con la deconstrucción de la metafísica? ¿Cuáles son los alcances de la crítica que la teoría política hace, desde la época de los totalitarismos, al autor de la República? ¿Qué valor cognoscitivo y pedagógico puede tener en mito platónico para filósofos cristianos que se ocupan del pensamiento platónico? ¿Cómo recibe la poesía hispanoamericana su voz de demiurgo? Estas preguntas, de las que se ofrecen diversas respuestas en este libro, son tratadas con rigor académico y confrontadas doblemente con las fuentes: en primer término, con Platón y luego con quienes son estudiados en el presente volumen, aunque desde ángulos muy diversos: M. Heidegger, H. G. Gadamer, K. Popper, E. Cassirer, L. Marechal. La seguridad del tratamiento metodológico y lingüístico que se refleja en esta obra hace que sea altamente recomendable para alumnos de grado y de posgrado en Filosofía, Teoría Política, Literatura y Humanidades en general.

In this work we deal with a general class of spatially distributed periodic SIS epidemic models with two time scales. We let susceptible and infected individuals migrate between patches with periodic time dependent migration rates. The existence of two time scales in the system allows to describe certain features of the asymptotic behavior of its solutions with the help of a less dimensional, aggregated, system. We derive global reproduction numbers governing the general spatially distributed nonautonomous system through the aggregated system. (...) We apply this result when the mass action law and the frequency dependent transmission law are considered. Comparing these global reproductive numbers to their non spatially distributed counterparts yields the following: adequate periodic migration rates allow global persistence or eradication of epidemics where locally, in absence of migrations, the contrary is expected.

Maria Triassi,1 Elena Giancotti,2 Antonio Nardone,1 Giulia Mancini,3 Fabiana Rubba1 1Public, Preventive and Social Medicine School, University Federico II of Naples, Naples, Italy; 2Procurement and Transplantation Coordination, Naples, Italy; 3Sociology Unit, G D'annunzio University, Chieti-Pescara, Italy Introduction: The growing disparity between organ availability for transplantation and the number of patients in need has challenged the donation and transplantation community to develop innovative processes, ideas, and techniques to bridge this gap. Advances in the sharing of best practices in the donation community (...) have contributed greatly to this aim over the past 5 years. Studies published during the past five years were analyzed to gain insight on the evolving organizational areas and tools that the procurement and transplantation pathways have been focused on. The hypothesis assessed is that networking and efficacious handling of this complex path may be ameliorated by an adaptive organizational toolbox. Methods: A thorough search has been conducted using various databases, ie, Cochrane library, PubMed, EMBASE, Federico II University Open Archive. The evidence was considered following the Effective Practice and Organization of Care Group checklist. Prevalent organizational attitudes and areas were assessed, and various scenarios were analyzed. Initially, all titles and abstracts were screened. In the next phase, the full text of all abstracts considered potentially relevant by at least one of the reviewers was evaluated. Inconsistencies in decision-making within this second phase were solved based on consensus between both reviewers. In this phase, for every study we defined whether the organization was considered relevant and what the scenario was. The information was extracted from each study based on bibliographic details. As many as 1,071 studies were analyzed, and 81 were selected as potentially relevant. Results: We found three prevalent areas of interest focused on organizational elements: global organizational strategies scenario, clinical hospital organization, and citizenship and social scenario. Conclusion: We reached the conclusion that organization has a central role in different scenarios of procurement and transplantation in a continuum from government to hospital and finally among citizens. A standardized hospital pathway definitely remains the essential step in order to ameliorate either procurement or transplantation. Keywords: transplant procurement, management, organizational tool, network. (shrink)

Originally published in 1951, Homo Faberis an examination of the scientific outlook on human mental evolution through the lens of parapsychology. The book aims to undermine what its terms, the 'scientific outlook' examining the human interpretation of the world, and the preconceived scientific concepts that reality does not extend beyond the realm that our senses reveal. The book expands upon this and moves to examine the broader human understanding of the entire cosmos, challenging the scientific conception that this can be (...) grasped in principal by human intellect, arising from the chance combination of material particles. The book argues that the scientific outlook prevents humans from discovering in the Universe the meaning and purpose which are everywhere to be found if sought in the appropriate contemplative states of mind. This book provides a unique take on the examination of human psychology and the evolution of the brain from an alternative scientific stance. It will be of interest to anthropologists, historians and psychologists alike. will be of interest to anthropologists, historians and psychologists alike. (shrink)

Impartiality is primarily a feature of normative or evaluative deliberation – deliberation about what ought to be done or about something's goodness or badness. An initial description is this: such deliberation is impartial when it is not unduly influenced by the deliberator's own interests, preferences, or loyalties. Derivatively, impartiality can be attributed to actions that are guided by deliberation with this feature, or persons who characteristically deliberate or act in this way.

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A (...) at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem. (shrink)

One of the ways of dividing all philosophers into two kinds is by saying of each whether he is an ordinary man's philosopher or a philosophers' philosopher. Thus Plato is a philosophers' philosopher and Aristotle an ordinary man's philosopher. This does not depend on being easy to understand: a lot of Aristotle's Metaphysics is immensely difficult. Nor does being a philosophers' philosopher imply that an ordinary man cannot enjoy the writings, or many of them. Plato invented and exhausted a form: (...) no one else has written such dialogues. So someone with no philosophical bent, or who has left his philosophical curiosity far behind may still enjoy reading some of them. (shrink)

Rapid developments in Artificial Intelligence are leading to an increasing human reliance on machine decision making. Even in collaborative efforts with Decision Support Systems (DSSs), where a human expert is expected to make the final decisions, it can be hard to keep the expert actively involved throughout the decision process. DSSs suggest their own solutions and thus invite passive decision making. To keep humans actively ‘on’ the decision-making loop and counter overreliance on machines, we propose a ‘reflection machine’ (RM). This (...) system asks users questions about their decision strategy and thereby prompts them to evaluate their own decisions critically. We discuss what forms RMs can take and present a proof-of-concept implementation of a RM that can produce feedback on users’ decisions in the medical and law domains. We show that the prototype requires very little domain knowledge to create reasonably intelligent critiquing questions. With this prototype, we demonstrate the technical feasibility to develop RMs and hope to pave the way for future research into their effectiveness and value. (shrink)
