La convicción de que los fenómenos y procesos naturales podían ser representados en un espacio físico regido por la geometría euclídea actuó en la ciencia clásica como supuesto epistemológico fundamental de la creación teórica. La posibilidad de un análisis matemático del continuo garantizaba, en efecto, una descripción intuitiva y pictórica de las trayectorias de los móviles estudiadas por la dinámica, así como una determinación precisa de los efectos producidos en el seno de las relaciones causales. Fueron convicciones y supuestos que (...) tuvieron que ser revisados en el momento en que el cuanto de acción de Planck obligó a desarrollar una nueva... física de los sistemas atómicos. Las consecuencias, no obstante, se dejarían sentir no sólo en el ámbito de la Física sino en todas aquellas regiones de la ciencia natural, como la Biología, que tenían que construirse bajo la cobertura conceptual de la naciente mecánica. El presente trabajo es una reflexión sobre los problemas filosóficos planteados en el encuentro entre la física del átomo y la química de las moléculas.

El trabajo intenta mostrar, a partir de una introducción historiografica, uno de los modos posibles en que pueden vincularse el sistema filosófico de Nicolas de Cusa [1401 -1464], a traves de la reformulación que hace el Cusano de la coincidentia oppositorum en el Trialogus De possest' [1460], con la teoria sustancialista de Baruch de Spinoza [1632 -1677], tal como es presentada en el Liber Primus de su Ethic.

Normal 0 21 false false false MicrosoftInternetExplorer4 On February 12, 1440 Nicholas of Cusa (1401-1464) concludes in his birthplace of Kues drafting the first major systematic formulation of his thinking: De docta ignorantia . The main category of his metaphysics in this context, i.e. the maximum , is analyzed and interpreted by him on three considerations: the maximum in an absolute sense, as contracted and finally as absolute and contracted, at the same time. In the context of the First Book, (...) which presents the singular methodology of the docta ignorantia , considers the maximum in itself in light of the paradoxical concept of coincidentia oppositorum in the absolute. In the final chapters of this first book tackles the critical of the theological discourse and thus, the problem of the ineffable name of maximum et minimum absolutum . Hence the purpose of this work is the further on cusan’s evaluation of language problem as it shows through treatment of the theological discourses and divine names that emerge from them, in light of the way of docta ignorantia.

El artículo estudia la relación entre realidad, pensamiento y lenguaje en la filosofía de Arthur Schopenhauer a la luz de la noción de fragmento. Explora, primero, lo que se ha dado en llamar una “escritura fragmentaria”, i.e. un género literario propio del Romanticismo que Schopenhauer practica especialmente en su legado manuscrito. En segundo lugar, trata la noción de fragmento a la luz del problema general de la representación, esto es, la condición fragmentaria del pensamiento. En tercer lugar, muestra la presencia (...) del concepto de fragmento en el contexto de la metafísica de la voluntad. Por último, a partir del desarrollo previo, ofrece una consideración de conjunto sobre el sentido de la relación entre realidad, pensamiento y lenguaje en la obra de Schopenhauer a partir del concepto de fragmento.

Cell division is an universal process the aim of which is the equitable distribution of subcellular organelles from single cells to their daughters. The extraordinary accuracy with which the genetic material is partitioned requires a complex machinery involving many gene products. Genetic approaches can be used to identify the relevant components and processes, and mutational analysis of loci essential for cell division has been carried out in several eukaryotes, in particular fungi and mammalian cells in culture. Recently, this type of (...) analysis has been extended to Drosophila, an ideal eukaryote for genetic studies. We will review here the genetic dissection of mitosis in Drosophila melanogaster, discussing recent findings of interest and the methodological problems that have been encountered. (shrink)

An intelligent model of the incremental capacity curve of an automotive lithium-ferrophosphate battery is presented. The relative heights of the two major peaks of the IC curve can be acquired from high-current discharges, thus enabling the state of health estimation of the battery while the vehicle is being operated and in certain cases, aging mechanisms can be suggested. Our model has been validated using a large dataset representing different degradation scenarios, obtained from a recently available open-source database.

The logic BN4 can be considered as the 4-valued logic of the relevant conditional and the logic E4, as the 4-valued logic of entailment. The aim of this paper is to endow E4 with a 2-set-up Routley-Meyer semantics. It is proved that E4 is strongly sound and complete w.r.t. this semantics.

Después de 40 años tras la revolución kuhniana en filosofía de la ciencia es clara la necesidad de un estudio interdisciplinar de la ciencia. Pero no se ve que sea posible el que la filosofía tenga algo que decir en tal marco interdisciplinar de análisis empírico. La tendencia general a la naturalización parece dejar fuera de juego a una disciplina, la filosofía, cuyo tradicional estilo normativo es muy difícil de asimilar. Con todo, la polémica continúa. En estas páginas se recoge, (...) entre algunos otros problemas, el enfrentamiento contemporáneo entre el racionalismo filosófico y el relativismo en la comprensión de la naturaleza de la ciencia.

According to selective, retentive, scientific realism, past empirical success may be explained only by the parts of past theories that are responsible of their successful predictions being approximately true, and thus theoretically retained, or approximated, by the parts of posterior theories responsible of the same successful predictions. In this article, we present as case study the transit from Ptolemy’s to Kepler’s astronomy, and their successful predictions for Mars’ orbit. We present an account of Ptolemy’s successful prediction of Mars’ orbit from (...) Kepler’s perspective, and scrutinize whether the theoretical elements responsible for Ptolemy’s empirical success are approximately retained in Kepler. In order to give to the realist the best chances, we try different strategies. We conclude that all fail and thereby this case constitutes a prima facie strong anomaly for selective retentive realism. Structural realists may call preservation of structure to the rescue, but the existing notions of structure do not work. In absence of a new notion that works, the burden of the proof lies on the realist side. (shrink)

Valerie Plumwood introduced in "Some false laws of logic" a series of arguments on how the rules Exported Syllogism, Disjunctive Syllogism, Commutation, and Exportation are not acceptable. Based on this we define the class of Plumwood algebras - logical matrices that do not verify any of these theses. Afterwards we provide conditional variants of the characteristic matrix of the logic RM3 that are also Plumwood algebras. These matrices are given an axiomatization based on First Degree Entailment and are endowed with (...) Belnap-Dunn Semantics. Finally we provide results of Soundness and Completeness in the strong sense for each of the defined variants. (shrink)

For several decades, tourism has mainly been identified as an activity that helps people escape their everyday routines, contributes to understanding between cultures, and promotes economic wellbeing. These assumptions have been questioned in both the public sphere and academic research, however. In this context, tourism research is increasingly drawing on ethical frameworks to support its criticism of tourism. Some of the most outstanding research on this issue is by Dean MacCannell, Emeritus Professor at the University of California at Davis and (...) author of one of the seminal works of the social theory of tourism: The Tourist: A New Theory of the Leisure Class (1976). MacCannell examines the moral and ethical aspects of tourism in all his writing, but they are the focal point of his book The Ethics of Sightseeing (2011), in which he identifies the tourists’ responsibility to mediate between their understanding of their own pleasure and the ethical repercussions of the late modern imperative, “Enjoy!”. During the Touriscape congress in Malaga, Spain, in February 2018, MacCannell talked about ethics and tourism with José Luis López, who prepared this interview for Recerca. (shrink)

Evaluative markers of diminution and augmentation typically express quantity or intensity. Prior evidence suggests that they also convey emotions, although it remains unexplored as to whether this function is mediated by their role in expressing quantification/intensification. Here we investigated the effects of evaluative suffixes on the assessment of word affective properties by asking participants (N = 300) to score valence and arousal features for augmentatives, diminutives and base words with negative, positive or neutral valence. Diminutives and, to a lesser extent, (...) augmentatives were assessed more positively than base forms in negative words and more negatively than bases in positive words. The capacity of diminution to express attenuated emotions is in line with its function in conveying quantity. By contrast, valence effects for augmentatives suggests a role in expressing pejoration and amelioration that is not mediated by quantification. With regard to arousal, negative, neutral and positive augmentatives showed higher scores than base words, which, in addition, were also rated higher than diminutives. These incremental effects suggest that suffixes which convey larger quantity are also associated with increased arousal. Thus, with the exception of valence effects in augmentatives, it seems that evaluative suffixes encode both valence and arousal through quantification. (shrink)

La principal preocupación ética en una sociedad tecnocientífica es la responsabilidad con la que se manipula el ambiente y las consecuencias que este desate ante un trato desmesurado o despreocupado. Hans Jonas apuesta a favor de la libertad de nuestras acciones como principal eje con el que nos relacionamos responsablemente con el mundo. En el siguiente artículo discutiremos sobre el poder y el deber humano bajo la lupa de la responsabilidad, y en definitiva, sobre la revalorización ontológica de la Naturaleza (...) y la preservación del ser en este nuevo horizonte ético que fundamenta Jonas como el nuevo corazón de la ética del futuro. Algunas de las preguntas clave serán: ¿qué ocurre con el pronóstico de las consecuencias de una acción para la humanidad y para con la Naturaleza? ¿qué es y de qué forma hablamos de la responsabilidad? ¿cuántos errores y pruebas podemos permitirnos en una cadena de eventos tecnológicos donde está en juego el futuro de la humanidad y su dignidad como condición imprescindible?

Aim: The presence of noise in urban environments is rarely considered a factor that causes damage to the environment. The primary generating source is transportation means, with vehicles being the ones that affect cities the most. Traffic noise has a particular influence on the quality of life of those who are exposed to it and can cause health alterations ranging from annoyance to cardiovascular diseases. This study aims to describe the relationship between the traffic noise level and the perceived annoyance (...) in the inhabitants of a city on the Northern Border of Mexico. The work carried out in a city represents the vulnerability characteristics: economic, social, and migratory of its sizable portion of the inhabitants. Due to that, it is impossible to identify precisely the number of residents as the number of vehicles in circulation.Methods: The streets and avenues with an annual average daily traffic of more than 1,000 vehicles were considered for the measurement of traffic noise. The equipment used was a vehicle gauge with non-invasive speed radar; type I integrating sound level meters, with their respective gauges and tripods. A questionnaire was applied to people living within 250 m of the streets and avenues in which the noise was measured.Results: The noise measurement found a parameter of LAeq estimated for 12 h during the day, exceeding 70 dBA. The data received from the questionnaire were statistically tested by using Pearson's correlation tests. A total number of 2,350 people were participated, of whom 1,378 were women and 972 were men. The age of participants is ranged from 18 to 75 years. The overall perception of traffic noise annoyance identified that 1,131 participants responded “Yes” as they considered the noise annoying. Participants who responded “No” as well as those who responded “Do not know” resulted in a total of 1,219 people.Conclusion: The results show that the population is desensitized to traffic noise and does not perceive it as an annoyance. The flow of vehicles and the type of vehicles are the significant factors for the propagation and increase in the traffic noise levels. Women present a considerable appreciation of traffic noise perception instead of younger people who demonstrate a higher tolerance to high-level exposure. This reflects the lack of information of the population around the noise problem and its effects. (shrink)

Designated bishop of Silves, diocese of Faro, Algarve, in 1334, D. Alvaro Pelayo entered in conflict with Alfonso IV (1325-57), the King of Portugal, sending him two letters in that one can notice that there he also had to defend the jurisdictional autonomy of the spiritual power, in order to the centralizing politics that the king, following his father’s steps, D. Dinis (1279-1325), gave continuity, with the purpose of restricting the political space of the high Lusitanian clergy. Past some few (...) years, (1347) for the same reason, the conflict of the relationships of power among the two authorities increased. Our purpose here is double: to analyze the historical facts related with the two mentioned conflicts, well as the aspects doctrinal contents in the two referred letters, with view to show the thought coherence and attitude of D. Alvaro Pelayo. (shrink)

The logic BN4 was defined by R.T. Brady in 1982. It can be considered as the 4-valued logic of the relevant conditional. E4 is a variant of BN4 that can be considered as the 4-valued logic of entailment. The aim of this paper is to define reduced general Routley-Meyer semantics for BN4 and E4. It is proved that BN4 and E4 are strongly sound and complete w.r.t. their respective semantics.

El Papa Francisco dice que la Iglesia quiere: “estudiar criterios y modalidades nuevas para que las mujeres no se sientan invitadas sino participantes a título pleno en los distintos ámbitos de la vida social y eclesial”.

Es evidente que ha llegado el momento de desbloquear las prevenciones y miedos para abordar este asunto, desde todos los aspectos (...) posibles y con la máxima honestidad. Un detenido análisis muestra que, en relación a la corresponsabilidad eclesial de las mujeres, hay contradicciones, lagunas y contrastes. (shrink)

La teoría clásica de las ideas innatas conoció en las últimas décadas un resurgir de la mano de filosofía chomskyana del lenguaje y la mente al amparo de una coartada genética. Sin embargo, la clarificación del alcance del papel de los genes en el desarrollo y de la complejidad y pluralidad de los sistemas en que aquellos se integran ha ensombrecido, si no apagado definitivamente, la infuencia del planteamiento. En este trabajo se argumenta, además, que históricamente se produjo un efecto (...) semejante con el innatismo cartesiano, al ser interpretado como un modelo disposicional de lo innato y acomodado al modelo epigeneticista del desarrollo orgánico. El precio de la supervivencia de alguna forma de innatismo parece ser el de permanecer aislado de cualquier lectura naturalista o científica y reafirmarse como una postura metafísica, epítome de la cual sería el modelo monadológico de Leibniz.
