We present here a direct elementary construction of continuous utility functions on perfectly separable totally preordered sets that does not make use of the well-known Debreu’s open gap lemma. This new construction leans on the concept of a separating countable decreasing scale. Starting from a perfectly separable totally ordered structure, we give an explicit construction of a separating countable decreasing scale, from which we show how to get a continuous utility map.

We show that the Lascar group $\operatorname {Gal}_L$ of a first-order theory T is naturally isomorphic to the fundamental group $\pi _1|)$ of the classifying space of the category of models of T and elementary embeddings. We use this identification to compute the Lascar groups of several example theories via homotopy-theoretic methods, and in fact completely characterize the homotopy type of $|\mathrm {Mod}|$ for these theories T. It turns out that in each of these cases, $|\operatorname {Mod}|$ is aspherical, i.e., (...) its higher homotopy groups vanish. This raises the question of which homotopy types are of the form $|\mathrm {Mod}|$ in general. As a preliminary step towards answering this question, we show that every homotopy type is of the form $|\mathcal {C}|$ where $\mathcal {C}$ is an Abstract Elementary Class with amalgamation for $\kappa $ -small objects, where $\kappa $ may be taken arbitrarily large. This result is improved in another paper. (shrink)

In the problem of Meaning and Error, Epistemology, Logic, Psychology, and Etymology, all find an inevitable point of contact. It is necessary to go back little more than half a century to see something of the changes which have resulted in the present epoch of disintegration.

This is an informative dossier on research work published since 2001 and connected with the field of rumors and urban legends. It includes reviews of eight French publications, seven publications in English, including two encyclopedias, two works from Mexico and one each from Italy and Sweden. The reviews are provided by a range of international scholars.

Why do women have more difficulty pursuing research careers than men? Although this topic has been extensively investigated in industrialized countries, prior studies provide little comparative evidence from less-developed areas. Based on a survey of 293 scientists in Ghana, Kenya, and the Indian state of Kerala, this article examines gender differences on a variety of individual, social, and organizational dimensions. The results show small or nonexistent differences between women and men in individual characteristics, professional resources, and the organizational conditions under (...) which research is conducted. The article argues that a combination of educational and research localism increases the likelihood of restricted professional networks for women. Gender inequality in the research systems of the developing world may be based on systemic deficits in the acquisition of social rather than material resources. The most important implication is that educational policy for development should focus on international opportunities for women in the near future. (shrink)

Blindsight is the term commonly used to describe visually guided behaviour elicited by a stimulus falling within the scotoma (blind area) caused by a lesion of the striate cortex. Such is normally held to be unconscious and to be mediated by subcortical pathways involving the superior colliculus. Blindsight is of considerable theoretical importance since it suggests that destriate man is more like destriate monkey than had been previously believed and also because it supports the classical notion of two visual systems. (...) It is also of potential clinical importance, since it has been claimed recently that systematic practice in blindsight can lead to the recovery of normal visual function in patients with cortical lesions. From a review of the literature it is concluded that all of the phenomena of blindsight can be attributed either to light scatter into unimpaired parts of the visual field or to residual vision resulting from spared striate cortex. The possible contribution f other factors is also considered. It is concluded that blindsight studies have generally failed to control for such nonblindsight interpretations partly because of poor methodology and partly because of difficulties in defining the term.

The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...." (3) "the third thesis is that (...) the differences between the well-Known english writers on moral philosophy from sidgwick to the present day are of little importance." (staff). (shrink)

The interaction between cavity modes and optical transitions leads to new coupled light-matter states in which the energy is periodically exchanged between the matter states and the optical mode. Here we present experimental evidence of optical strong coupling between modes of individual sub-wavelength metamaterial nanocavities and engineered optical transitions in semiconductor heterostructures. We show that this behaviour is generic by extending the results from the mid-infrared to the near-infrared. Using mid-infrared structures, we demonstrate that the light-matter coupling occurs at the (...) single resonator level and with extremely small interaction volumes. We calculate a mode volume of 4.9 × 10 from which we infer that only ~2,400 electrons per resonator participate in this energy exchange process. (shrink)

The field of Philosophy of Sport has been developing in Anglo-Saxon scholarship since the 1960s and since then has achieved considerable consolidation. However, this is a progressing field in Latin American countries like Brazil. This paper aims to analyse the trajectory of the Philosophy of Sport in Brazil, presenting an overview of its development since the 1980s and some prospects that have been generated since the turn of the century. In conclusion, the article points out that the field of Philosophy (...) of Sport in Brazil is in the process of disciplinary consolidation, presenting a plurality of agents, institutions and theoretical approaches in its structure.

Derek Parfit’s view of personal identity raises questions about whether advance decisions refusing life-saving treatment should be honored in cases where a patient loses psychological continuity; it implies that these advance decisions would not be self-determining at all. However, rather than accepting that an unknown metaphysical ‘further fact’ underpins agential unity, one can accept Parfit’s view but offer a different account of what it implies morally. Part II of this article argues that contractual obligations provide a moral basis for honoring (...) advance decisions refusing life-saving and/or life-sustaining medical treatment; advance decisions have similarities to contracts, such as life insurance policies and will-contracts, that come into effect when the psychological discontinuity is through death.

It is a commonly accepted view that men think to live, and do not live to think, that conation, and not cognition, is the primary object of living. Impression, affect, and expression constitute the complete psychic process. The term philosophy, the love of wisdom, also suggests that man's thought has a practical and not a theoretical objective. In this connection, however, two errors must be avoided: on the one hand an exaltation of the intellect as in rationalism, and on the (...) other hand a depreciation of the intellect as in pragmatism.

The poet’s words: “A man’s reach should exceed his grasp” are not merely a command of whatought to be, they are a description of what is. Man has always been stretching himself beyond his own measure. He has a sense of the Infinite: Eternity has been set in his heart: he has not been content to look only on the things seen, his gaze has ever been towards the Unseen. Whatever stage of development he may have reached, he seeks for, (...) and strives after, what is above and beyond himself and his world. In science he tries to get behind thephenomenalreality as his senses apprehend it, to thenoumenal, mind. In philosophy he endeavours to bring the multiplicity of his experience, outer and inner, into a unity that will evidence itself to his reason as coherent, and not contradictory. In morality he is not content with the customs and standards of the society of which he is a member; but conscious of their inadequacy, he conceives and aspires to realize an ideal adequate to his nature; hisought to beis always challenging hisis. The impulse or motive of progress in all spheres of human interest and activity is “the best is yet to be.”. (shrink)
