We recently found orientation constancy with respect to direction of gravity in the alert monkey. This seems to rely on a polysensory interaction that involves different sense-specific reference frames. Thus, we will challenge the assumption that the sense-specific reference frames are mutually exclusive. At the same time, we will highlight the dynamic tuning of the receptors that might rely on cross-modal mechanisms.

This paper offers a two dimensional variation of Standard Deontic Logic SDL, which we call 2SDL. Using 2SDL we can show that we can overcome many of the difficulties that SDL has in representing linguistic sets of Contrary-to-Duties (known as paradoxes) including the Chisholm, Ross, Good Samaritan and Forrester paradoxes. We note that many dimensional logics have been around since 1947, and so 2SDL could have been presented already in the 1970s. Better late than never! As a detailed case study (...) illustrating the power of 2SDL, we examine the system DL of Deontic Logic of Andrew Jones and Ingmar Pörn offered in 1985 to solve the Chisholm paradox of Contrary to Duties. The critical examination is done using logics and methods available in 1985 and solutions are proposed using what was available in 1985. (shrink)

In the light of partial understanding, we examine the thesis that concepts are individuated in terms of possession conditions and show that adherents face a fatal dilemma: Either concept-individuating possession conditions include cases of partially understood concepts or not. If yes, possession conditions do not individuate concepts. If no, the thesis is too restricted and lacks a minimally satisfactory level of generalization.

Pickering & Garrod (P&G) put forward the interesting idea that language production relies on forward modeling operating at multiple processing levels. The evidence currently available to substantiate this idea mostly concerns sensorimotor processes and not more abstract linguistic levels (e.g., syntax, semantics, phonology). The predictions that follow from the claim seem too general, in their current form, to guide specific empirical tests.

This paper presents a design for the multivariable control of a cooling system in a PEM fuel cell stack. This system is complex and challenging enough: interactions between variables, highly nonlinear dynamic behavior, etc. This design is carried out using a multiobjective optimization methodology. There are few previous works that address this problem using multiobjective techniques. Also, this work has, as a novelty, the consideration of, in addition to the optimal controllers, the nearly optimal controllers nondominated in their neighborhood. In (...) the multiobjective optimization problem approach, the designer must make decisions that include design objectives; parameters of the controllers to be estimated; and the conditions and characteristics of the simulation of the system. However, to simplify the optimization and decision stages, the designer does not include all the desired scenarios in the multiobjective problem definition. Nevertheless, these aspects can be analyzed in the decision stage only for the controllers obtained with a much less computational cost. At this stage, the potentially useful alternatives can play an important role. These controllers have significantly different parameters and therefore allow the designer to make a final decision with additional valuable information. Nearly optimal controllers can obtain an improvement in some aspects not included in the multiobjective optimization problem. For example, in this paper, various aspects are analyzed regarding potentially useful solutions, such as the influence of certain parameters of the simulator; the sample time of the controller; the effect of stack degradation; and the robustness. Therefore, this paper highlights the relevance of this in-depth analysis using the methodology proposed in the design of the multivariable control of the cooling system of a PEM fuel cell. This analysis can modify the final choice of the designer. (shrink)

Xavier Landes | : In this article, consensus, defined as the consent of all citizens, is argued to be the first best for part of the liberal tradition on political legitimacy. Consensus would be the foundation of the liberal society that, when out of reach, needs to be approximated through, for instance, voting. I build on the timid attempts in political theory at using the theorem of the second best as a tool to settle difficult decision making in applied (...) political theory. More precisely, I defend the view that consensus would be the first best for part of the liberal tradition on political legitimacy. Furthermore, I illustrate how moral, factual, disagreements may create second-best problems, especially in terms of stability. Finally, I spell out some reasons why such problems directly affect a liberal order, on pragmatic grounds. The final purpose is to contribute to the literatures on legitimacy and on the application of the theorem of the second best outside economics. The key idea is to stress that much more work has to be done for “importing” the theorem of the second best into political theory. | : Dans cet article, le consensus, défini comme le consentement de tous les citoyens, est présenté comme remplissant la fonction d’optimum de premier rang [first best] pour une partie de la tradition libérale quant à la légitimité politique. Le consensus fonderait la société libérale qui, lorsque hors d’atteinte, nécessiterait d’être approximer au travers, par exemple, du vote. Je m’appuie sur les timides tentatives en théorie politique d’utiliser le théorème de l’optimum de second rang [second best] comme outil pour résoudre des prises de décision difficiles en théorie politique appliquée. Plus précisément, je défends l’idée que le consensus serait l’optimum de premier rang pour une partie de la tradition libérale quant à la légitimité politique. De plus, j’illustre comment les désaccords moraux, factuels peuvent créer des problèmes d’optimum de second rang, en particulier en termes de stabilité. Enfin, j’expose quelques raisons pour lesquelles de tels problèmes affectent directement un ordre libéral, d’un point de vue pragmatique. Le but final est de contribuer aux littératures sur la légitimité et sur l’application du théorème d’optimum de second rang à l’extérieur des sciences économiques. L’idée principale est de souligner qu’il reste beaucoup de travail afin d’« importer » le théorème d’optimum de second rang en théorie politique. (shrink)

This article proposes to analyse some aspects of the appropriation of New School thinking in Brazil, particularly Deweyan pragmatism, in the 1950s and 1960s. The analysis is based on the assumption that the developmentalist ideology that punctuated the debate on the economic, political and social restructuring of the country in these two decades constituted fertile ground for the return and expansion of pragmatist thinking amongst Brazilian educators, articulating itself, sometimes in contradictory ways, with this ideology. The focus of the analysis (...) will be on the writings of the group of educators which circulated around the figure of Anísio Teixeira, at the time director of the National Institute for Pedagogic Studies, an organ linked to the Ministry of Education and Culture, which set itself the task of producing research that would support public policy in the field of education, as well as constituting itself as a center for teacher education and the stimulus and development of innovative experiences in the public school system. The appropriation of Deweyan pragmatism, in this context, had a triple perspective: pragmatism as scientific method, implying a specific conception of science, particularly the social sciences, with emphasis on the application of scientific knowledge in the solution of practical problems; as a way of democratic life; and as a synonym for experimentalism, in the sphere of schooling.

Rudist buildups are important reservoirs in many Cretaceous fields in the Middle East, but they are generally near or below seismic resolution. The dimension, shape, and architecture of rudist buildups can be assessed using outcrop, although only partly so because of pseudo-2D observations of geobodies intersecting with the outcrop. We used ground-penetrating radar to enhance our understanding of the shape, dimension, and architecture of Albian rudist buildups in two outcrops in Texas. In the Lake Georgetown spillway, caprinid rudist buildups are (...) 10–30 m wide and 2–7 m high. They are elliptical with an aspect ratio of as much as 1.7. They show no or very little flank development. The older buildup exposed in the Red Bluff Creek area displays 10- to 25-m-wide and 5- to 10-m-high in situ caprinid rudist mound core accumulations with as much as 100-m-wide reworked flanks in the shallower part of the depositional profile. Downdip along the depositional profile, caprinid buildups are 5–20 m wide and 3–7 m high with no flank debris. The buildups in the Lake Georgetown area have similar architecture and comparable size with the downdip buildups exposed in Red Bluff Creek. These buildups were compared with other outcropping Albian buildups in Texas that have different sizes, shapes, and stratigraphic architecture to provide dimensional data that could be used in subsurface reservoir modeling, either for calibrating variogram ranges or to build training images. The rudist buildups exposed in Texas are an order of magnitude smaller than those present in the subsurface in the Middle East, but they have comparable stratigraphic architecture. The size difference might be the result of subsurface buildups being mapped using well-log or core correlations or seismic extractions that cannot resolved at that scale of heterogeneity. (shrink)

Le but de cet article est double. Il s'agit d'une part de donner une représentation des verbes trilitères (i.e. comportant trois consonnes, autrement dit les verbes de forme CvCvC) du somali qui rend compte de l'ensemble de leurs propriétés. D'autre part, au travers de cet exemple d'analyse, je m'attache à discuter du rapport qu'entretient le phonologue avec les corpus, en particulier, leur constitution, leur exploitation, l'appréhension et la résolution des contre-exemples ; on verra aussi que l'analyse proposée (comportement des verbes (...) [CvCvC] du somali) ainsi que ses dividendes, capitaux pour la compréhension de la phonologie de cette langue, auraient été impossibles à obtenir ou du moins non crédibles sans l'utilisation de l'outil informatique. Dans le dernier paragraphe seront discutés les problèmes que posent la constitution de corpus électroniques ainsi que leur exploitation automatique. (shrink)

Why is man religious? To this fundamental question Paul Tillich and Xavier Zubiri respond similarly. However, they did not know each other personally and apparently neitherread the works of the other. The coincidence in their positions is without a doubt owing tothe influence that Martin Heidegger exercised on their thought. First, both defend themethod of correlation, according to which it is not possible to give answers to questionsthat nobody asks. Second, every question is born of a previous human experience (...) thatmakes it possible and that gives it meaning. Granting this, in the case of the questionabout God, what is that previous experience? For Tillich it is nothing other than that “thedimension of depth” in which we are confronted with “that which concerns us unconditionally,” whether we call it “God” or not. For Zubiri, this fundamental experience stems fromthe fact of “religation to a power of the real which is ultimate, possibilitating, and impelling.” From this fundamental experience is born the concern for the ultimate ground of ourexistence and the possible answers, which are none other that the diverse religions thatthere have been throughout history, including other apparently irreligious forms of life suchas atheism, agnosticism and the present-day indifference to religion.¿Por qué es religioso el hombre? A esta pregunta fundamental responden de maneraparecida Paul Tillich y Xavier Zubiri. Sin embargo, no se conocieron personalmente y alparecer ninguno leyó las obras del otro. La coincidencia en sus planteamientos se debensin duda a la influencia que M. Heidegger ejerció sobre el pensamiento de ambos. En primer lugar, los dos defienden el método de la correlación, según el cual no se pueden ofrecerrespuestas a preguntas que nadie se hace. Y, en segundo lugar, toda pregunta nace deuna previa experiencia humana que la hace posible y le da sentido. Esto supuesto, en elcaso de la pregunta por Dios, ¿cuál es esa previa experiencia? Para Paul Tillich no es otraque “la dimensión profunda” en la que nos encontramos enfrentados a “aquello que nosconcierne incondicionalmente,” lo llamémoslo o no Dios. Para Zubiri dicha experiencia fundamental tiene lugar en el hecho de la “religación al poder último, posibilitante e impelentede lo real”. De esta experiencia fundamental nace la preocupación por el fundamento último de nuestra existencia y las posibles respuestas, que no son otras que la diversas religiones que en la historia han sido e incuso otras formas de vida al parecer irreligiosas comoel ateísmo, el agnosticismo y la indiferencia actual.

Estimation of the repartition of asynchronous cells in the cell cycle can be explained by two hypotheses:– - the cells are supposed to be distributed into three groups: cells with a 2c DNA content (G0/1 phase), cells with a 4c DNA content (G2+M phase) and cells with a DNA content ranging from 2c to 4c (S phase); – - there is a linear relationship between the amount of fluorescence emitted by the fluorescent probe which reveals the DNA and the DNA (...) content. According to these hypotheses, the cell cycle can be represented by the following equation. (shrink)

«Jo només escric», diu l'autor, «quan les sensacions o idees se'm fan dimonis íntims que intento foragitar amb la literatura. Però no resulta fàcil sentir ni pensar amb naturalitat i seguretat, superar els propis vertígens i censures, deixar avançar la ment amb la confi ança que trobarà el que busca, la mateixa confiança amb què el rei s'asseu sense mirar enrere, segur que trobarà la cadira que algú li haurà acostat.Un entorn raonablement sensual i fins i tot una relativa gimnàstica (...) sexual ajuden sens dubte l'esperit: el que aquest no admet és cap lligam sentimental. Al cervell no li roba energia el moblament sensual o l'erotisme profilàctic, és a dir, tot allò que apaivaga un cos que ha de funcionar alhora com la seva font d'energia i el seu instrument. El pensament ens permet, doncs, el que ens estabilitza però no el que ens mobilitza; tolera el que ens gratifica però no el que ens sedueix. Més que en la repressió, el pensament i la cultura es basen en la fredor, s'aixequen sobre l'egoisme i es mantenen a força de narcisisme. Ens perdonen tal volta els plaers, però mai els amors».

El artículo analiza el concepto de la «muerte» en la filosofía del pensador español Xavier Zubiri, quien rechazó la habitual división del ser humano en cuerpo y alma, y propuso una concepción del hombre entendido como «totalidad psico-física». Esta concepción implica necesariamente la mortalidad del individuo, pero bajo la influencia del teólogo francés M.-É. Boismard, Zubiri plantea un concepto de «resurrección» del hombre como un todo, considerando un error hablar solo de una resurrección del cuerpo. Zubiri piensa que, gracias (...) a su libertad, el sujeto puede construir una «figura eterna» de su ser, que permanece para siempre, y alcanza la gracia de la vida eterna, dependiendo de que dicha figura la haya construido el sujeto en versión o aversión hacia la realidad suprema: Dios.

After the monumental works of Xavier Leon and Martial Guéroult, the French have again produced a significant piece of Fichte-interpretation. The author advances two radically new theses: Fichte's philosophy is above all centered around the deduction of the other, and even objectivity as such is based upon inter-subjectivity. The Doctrine of Science, instead of being the foundation of an absolute idealism, teaches that the only knowledge which can be had is empirical knowledge, and all logic is rooted in time. (...) Philonenko claims that Fichte's aim was to uphold the adequacy and essential correctness of common everyday knowledge over against the pretensions of metaphysical speculation. This is a magnificent book: the product of a truly amazing scholarship in the history of philosophy, full of ingenious and highly imaginative rapprochements and insights. It is also another welcome manifestation of that recent continental trend in the interpretation of German idealism which realizes that Fichte and Schelling do not simply fill the gap between Kant and Hegel, but are great philosophers in their own right. If any objection can be made at all against the work, it would be the limitation of its argument to the first period of Fichte's creativity. The author's avowed aim is to confine himself to the Grundlage der gesammten Wissenschaftslehre, and, as a matter of fact, we rarely find a quote later than 1798. Indeed, Fichte always claimed that no qualitative change took place in his thought. However, his exposition of it steadily altered, and in view of this, perhaps it is not entirely unjustified to regret that the Wissenschaftslehre of 1804 and the Answeisung zum seligen Leben are not taken into account in interpreting the early Fichte.—M.
