La industria alimentaria y las administraciones públicas realizan grandes esfuerzos para mejorar el mantenimiento de las condiciones higiénicas y evitar la contaminación de alimentos. Pese a estos esfuerzos siguen produciéndose un gran numero de procesos patológicos relacionados con los alimentos. Las buenas prácticas higiénicas pueden reducir el nivel de contaminación, pero algunos microorganismos patógenos resulta imposible eliminarlos, especialmente de aquellos alimentos que se comercializan crudos y con procesado mínimo. La irradiación se presenta como un método de descontaminación posible para este (...) grupo de alimentos, especialmente válido como método de descontaminación final. Dosis de irradiación inferiores a 10 kGy (dependiendo del alimento y condiciones) son efectivas para eliminar posibles patógenos no esporulados, inactivar parásitos, tratar especias, condimentos y otros ingredientes secos, fruta fresca y productos de cuarta gama (vegetales frescos, limpios y envasados, listos para consumo). Respecto a la seguridad de los alimentos irradiados, está plenamente demostrado que no provoca la aparición de compuestos especiales y provoca una ligera reducción en el contenido de algunas vitaminas, que es equiparable a la producida por otros tratamientos tecnológicos. Se ha visto también que microorganismos que han sido sometidos a radiaciones y han sobrevivido a ellas se muestran más sensibles a las condiciones ambientales de estrés que aquellos que nunca han sido irradiados. Pese a que los organismos internacionales FAO y OMS presentan la irradiación como un método seguro, eficaz, limpio con el medio ambiente y energéticamente eficiente, los consumidores siguen estando desinformados y mostrándose reticentes a su utilización. En la actualidad se están llevando a cabo muchos sondeos, de los que se deriva que una correcta in formación al consumidor es el único método válido para conseguir la aceptación de esta tecnología. Las investigaciones actuales en este sector se centran en la optimización de su aplicación a alimentos concretos y en los posibles efectos sobre los materiales de envasado. Por lo que respecta a la aplicación industrial, se tiende a crear centros de tratamiento donde diferentes productores llevan sus materias a tratar. Se espera que esta tecnología presente una fuerte tendencia creciente en los próximos años. (shrink)

In this discussion note, I defend Gaunilo's famous parody of Anselm's Ontological Argument for God's existence against a well-known objection due to Alvin Plantinga.

Stephen Law’s evil-god challenge is the argument that since an evil god is just as likely as the God of theism, there is no reason to believe that theism is true over believing there is a god who is omnipotent, omniscient, and omnimalevolent. There have been several attempts to answer the challenge, but recently John Collins has defended the evil-god challenge and also extended the argument past Law’s original formulation. In this article, I defend the classical theism of Thomas Aquinas (...) against the evil-god challenge. In particular, I explain how Aquinas’s theodicy involving God’s goodness and Aquinas’s privation view of evil avoid the challenge. (shrink)

Analysis of 'the common good' reveals moral elements in the concept. The common good, Traditionally regarded as a major political goal, Is served by measures that promote the interests of all citizens equitably, Within the limitations of 'the accepted morality'. Measures for the common good thus often impose moral restraints on individuals' interests, As numerous examples show. Positivist analyses are generally defective because they do not give the normative elements their proper place.

H. Tristram Engelhardt has made profound contributions to both philosophical and religious bioethics, and his philosophical and religious works may be read in mutually illuminating ways. As a philosopher, Engelhardt has mustered a powerful critique of secular efforts to develop a shared substantive morality. As a religious scholar, Engelhardt has affirmed a Christian bioethics that does not emanate from human rationality but from the experience of God found in Orthodox Christianity. In this collection of essays, both defenders and critics of (...) Engelhardt's religious bioethics have their say, and the spirited nature of their discussion attests, in its own right, to Engelhardt's enduring influence. (shrink)

Recovers some of the value in the Wittgensteinian period of philosophy, using certain logical systems: Prior's theory of operators and Hilbert's epsilon calculus. This work applies, discursively, the previous largely technical results published in Prolegomena to Formal Logic (Aldershot, Gower 1989) and Intensional Logic (Aldershot, Ashgate 1994) to resolve matters of current interest in philosophy, logic and linguistics - notably attacking a variety of realisms found in comtemporary cognitive science and the philosophy of mathematics.

Measurement of gravitomagnetic field is of fundamental importance as a test of general relativity. Here we present a new theoretical project for performing such a measurement based on detection of the electric field arising from the interplay between the gravitomagnetic and magnetic fields in the stationary axial-symmetric gravitational field of a slowly rotating massive body. Finally it is shown that precise magnetometers based on superconducting quantum interferometers could not be designed for measurement of the gravitomagnetically induced magnetic field in the (...) cavity of a charged capacitor since they measure the circulation of a vector potential of electromagnetic field, i.e., an invariant quantity including the sum of electric and magnetic fields, and the general-relativistic magnetic part will be totally cancelled by the electric one which is in good agreement with the experimental results.

"This title was first published in 2003.Developments in genetic science are opening up new possibilities for human beings; both the creation and the shaping of human life are now possible in the laboratory. As these techniques develop, questions are increasingly asked about how far everything that is scientifically possible should - morally, legally and socially - be pursued. Whilst much attention and policy-making has focussed on the development of regulation of technologies affecting human reproduction, regulation where plants and animals are (...) concerned is much more limited. In this book, developments in genetics are addressed in the broad sense by an international range of contributors. This includes not only issues such as eugenics and the modification of the human embryo, but also the genetic modification of plants and animals in the pursuit of commerce, agriculture and biomedical research. This book is published in association with the Society for Applied Philosophy"--Provided by publisher. (shrink)

The correctness of application of orientalist discourse of E. Said to the colonial policy of the Russian Empire is analyzed in the article on the example of P. I. Rychkov research. By studying integration of Bashkirs in the structure of the Russian state, the author came to the conclusion that Russia’s policy in the East was based on the experience of the management of non-Russian peoples, which was developed in the 16-17th centuries. The establishment of ‘cultural distance‘ is typical only (...) for a small group of educated administrators of past-Petrine era. Most of the officials of the region, as in the preceding period, and during the time of Rychkov and Tatishchev preferred to rely on traditional methods of Bashkir management, which was developed in the period of their voluntary accession. Managerial stereotypes of 16-17th centuries, had significant influence on policy towards South-Eastern peoples of Russia even in the 19th century. The Russian administration inherent in the desire to integrate the non-Russian peoples in the General class structure of the state on the basis of analogies or correspondences, the objective of which was social and cultural rapprochement of the two societies.

The ideas and conceptions of the Frankfurt philosophical-sociological school, above all the "critical theory of society," the principles of "negative dialectics" and the "great refusal," the utopia of "pacified existence," occupy an important place in the contemporary ideological struggle between the world systems of socialism and capitalism, and comprise a significant ideological and theoretical arsenal of bourgeois ideology and revisionism. And this is not accidental. The "critical theory of society" formulated and argued for by T. Adorno, M. Horkheimer, H. Marcuse, (...) J. Habermas, and others, which proclaims a protest against any social status quo, is used for the critique both of capitalism and actually existing socialism. At the same time it is also interpreted as an imaginary alternative to Marxism, and from, moreover, both right and "left" positions. Therefore the social theory of the Frankfurt school impacts upon the most diverse currents—from bourgeois social thought to the right and "left" varieties of revisionism. The complex evolution made by the representatives of this school in the last half-century contributed to this wide dissemination of the ideas of the Frankfurt school. Theoretical arguments are found in it both by those whose ideology, being directed to the progressive forces, is developed in the direction of Marxism, and by those who fled the soil of Marxism and are hostile to it.

The intellectual origins of molecular biology are usually traced back to the 1930s. By contrast, molecular biology acquired a social reality only around 1960. To understand how it came to designate a community of researchers and a professional identity, I examine the creation of the first institutes of molecular biology, which took place around 1960, in four European countries: Germany, the United Kingdom, France, and Switzerland. This paper shows how the creation of these institutes was linked to the results of (...) post-war economic reconstruction. Then, it compares how the promoters of these different institutional projects delimited the goals of their discipline, reflected on its history, and suggested how research should be organised. I show how they carefully positioned their new discipline within the emerging national science policy discourse of the 1950s, and aligned it with the current vision of scientific modernity. In particular, I discuss how they articulated the meaning of molecular biology with respect to five common themes: the role of physics in the atomic age, the relations between fundamental research and medical applications, the 'Americanisation' of scientific research, the value of science in the reconstruction of national identities, and the drive towards interdisciplinary research. This paper thus demonstrates that beyond the local and national accounts there is a European history of molecular biology. (shrink)

This is a collection of 15 papers from “philosophers, social scientists, and academic lawyers” concerned with “the field of bioethics itself”, “bioethics’s role in contemporary society”, and “specific issues”, including some—such as the role of the pharmaceuticals—not often addressed in such collections. They have all been commissioned for the volume either by or through the Social Philosophy and Policy Foundation, located in the USA, on whose behalf Cambridge University Press has published it in the UK. Perhaps, then, it is not (...) surprising that it …. (shrink)
