A hemi-implicative lattice is an algebra \((A,\wedge,\vee,\rightarrow,1)\) of type (2, 2, 2, 0) such that \((A,\wedge,\vee,1)\) is a lattice with top and for every \(a,b\in A\), \(a\rightarrow a = 1\) and \(a\wedge (a\rightarrow b) \le b\). A new variety of hemi-implicative lattices, here named sub-Hilbert lattices, containing both the variety generated by the \(\{\wedge,\vee,\rightarrow,1\}\) -reducts of subresiduated lattices and that of Hilbert lattices as proper subvarieties is defined. It is shown that any sub-Hilbert lattice is determined (up to isomorphism) by (...) a triple (_L_, _D_, _S_) which satisfies the following conditions: _L_ is a bounded distributive lattice, _D_ is a sublattice of _L_ containing 0, 1 such that for each \(a, b \in L\) there is an element \(c \in D\) with the property that for all \(d \in D\), \(a \wedge d \le b\) if and only if \(d \le c\) (we write \(a \rightarrow _D b\) for the element _c_), and _S_ is a non void subset of _L_ such that _S_ is closed under \(\rightarrow _D\) and _S_, with its inherited order, is itself a lattice. Finally, the congruences of sub-Hilbert lattices are studied. (shrink)

A la memoria del maestro/filósofo Álvaro B. Márquez-Fernández La necesidad de seguir promoviendo temas “no” vistos de forma positiva por los grupos cerrados del poder, y aquellos que han hecho de la academia grupúsculos tradicionales, sistémicos y funcionales a los intereses de los de arriba, se constituye en una apuesta de ir a contracorriente de esos tipos de historias y asumir un compromiso ético-político en función de las luchas, los sentimientos y las emociones de los grupos de abajo.

The purpose of this study is to identify the elements that can be implemented to achieve an ethical infrastructure, in small and medium enterprises. The ethical infrastructure is considered as a set of formal and informal systems, leadership, climate and culture, related to ethical issues. The research was carried out through interviews and focus groups with managers from 28 companies in Madrid, all signatories to the Global Compact. The identified key elements in SMEs are leadership, informal managerial and formal communication. (...) This study also explores different factors that influence the effectiveness, implementation, and sustainability of the ethical infrastructure in SMEs, discovering some factors that can act as both accelerators and barriers such as pressure from customers. Additional findings regarding the concepts of ethics and corporate social responsibility in SMEs, dilemmas and characteristics of the culture and climate are also presented. (shrink)

An experimental study was designed to analyze the effect of school-based training in self-regulation learning strategies on academic performance. Class-level variables were considered and the effects of the intervention were measured at the end of the intervention and 3 months later. A sample of 761 students from 3rd and 4th grades, from 14 schools, participated in the study. Data were analyzed using three-level analysis with within-student measurements at level 1, between-students within-classes at level 2, and between-classes at level 3. Data (...) showed a positive effect of the intervention on student performance, both at post-test and at follow-up considering the four school subjects together. However, the effect was significant just at follow-up when subjects were considered separately. Student performance was significantly related to the students’ variables and the context. Finally, students’ gender and level of reading comprehension, as well as the teacher’s gender, were found to moderate the effect of the intervention on students’ academic performance. Two conclusions were highlighted: first, data emphasize the importance of considering time while conducting intervention studies. Second, more teaching experience does not necessarily translate into improvements in the quality of students’ instruction. (shrink)

The aim of this study was to evaluate the neuromuscular response to an agility and repeated sprint ability test according to the level of competition in futsal players. A total of 33 players from two elite teams and one amateur team participated in the study. The participants completed an agility t-test, a 30 m-speed test, and a RSA test. A countermovement jump test and a tensiomyography test of the rectus femoris and biceps femoris of both legs were carried out before (...) and after the tests. RSA test revealed better sprint times in elite players compared to amateurs in the seven bouts, as well as in the 30 m sprint and in the agility test. In conclusion, elite players showed greater performance in the RSA test, in the 30 m tests and in the agility test compared to amateur players. The contractile properties were not a key factor in the RSA performance of the futsal players. (shrink)

The progress of Mathematics during the nineteenth century was characterised both by an enormous acquisition of new knowledge and by the attempts to introduce rigour in reasoning patterns and mathematical writing. Cauchy’s presentation of Mathematical Analysis was not immediately accepted, and many writers, though aware of that new style, did not use it in their own mathematical production. This paper is devoted to an episode of this sort that took place in Spain during the first half of the century: It (...) deals with the presentation of a method for numerically solving algebraic equations by José Mariano Vallejo, a late Spanish follower of the Enlightenment ideas, politician, writer, and mathematician who published it in the fourth (1840) edition of his book Compendio de Matemáticas Puras y Mistas, claiming to have discovered it on his own. Vallejo’s main achievement was to write down the whole procedure in a very careful way taking into account the different types of roots, although he paid little attention to questions such as convergence checks and the fulfilment of the hypotheses of Rolle’s Theorem. For sure this lack of mathematical care prevented Vallejo to occupy a place among the forerunners of Computational Algebra. (shrink)

La vida y obra de José Luis Aranguren siguen siendo válidas no sólo desde el punto de vista del pensamiento ético, sino también de la toma de conciencia del papel de los laicos en la Iglesia. La utilización por Aranguren de las ideas filosóficas de Zubiri para el estudio de la ética es una de las aportaciones más relevantes del pensamiento contemporáneo. A Aranguren hay que reconocerle la persistente relevancia que la Filosofía Moral tiene en nuestra tradición cultural.

Assessing physical fitness has emerged as a proxy of the health status of children and adolescents and therefore as relevant from a public health point of view. DAFIS is a project included in Plan Galicia Saudable of the regional government of Galicia. DAFIS consists of an on-line software devoted to record the results of a standard physical fitness protocol carried out as a part of the physical education curriculum. The aims of this study were: to obtain normative values of physical (...) fitness of the Galician school population evaluated in the DAFIS project, and to identify a reduced number of components and tests able to capture a significant amount of the variability in the physical fitness of children and adolescents. From an initial sample of 27784 records, 15287 cases were considered after filtering. Generalized Additive Models for Location, Scale and Shape were used for obtaining percentile curves and tables for each sex. Furthermore, a principal components analysis was performed, selecting the number of components by applying the Kaiser’s rule and selecting a subset of variables considering the correlation between each variable and the components. Percentile curves and normative values are reported for each test and sex. Physical fitness was better in boys than in girls throughout age groups, except for flexibility that was consistently higher in girls. Two main components were detected throughout age groups: the first one representing body composition and partially cardiorespiratory fitness and the second one muscular fitness. For boys and girls, waist to height ratio had the highest correlations with the first component in four out of six age groups. The highest correlation with the second component, was most frequently observed for the handgrip test both in boys and girls. This study provides evidence about the utility of school community actions like DAFIS aimed to track the health-related fitness of children and adolescents. The results suggest that fat mass distribution and muscular performance concentrate a high proportion physical fitness variance. (shrink)

At Universitat Politècnica de València, Meridies, an internship programme that places engineering students in countries of Latin America, is one of the few opportunities the students have to explore the implications of being a professional in society in a different cultural and social context. This programme was analyzed using the capabilities approach as a frame of reference for examining the effects of the programme on eight student participants. The eight pro-public-good capabilities proposed by Melanie Walker were investigated through semi-structured interviews. (...) The internship is an environment in which students can put into practice the knowledge they have acquired in undergraduate studies and to find practical relevance in what they studied. Occasionally, this also entails a critical questioning of what they have learned, a greater awareness of the limits of the contents of their studies and of the way things were taught, and interest in less explored issues that are closely linked to social justice. However, tensions can arise between the pro-public-good oriented perspectives of this programme, and a more instrumental vision. One way to overcome these tensions is to foster consideration of reflexivity, that is, the dynamic relationship between technology and society. To do so, the programme must create space before and during the internship, and upon the return of the students, to discuss and collectively reflect upon their lived experience. Additionally, it ought to engage supervisors in this educational journey, both at the university and in the host institutions, and also involve socially committed organisations in this task.

Human beings have imaged ideal societies across the time, with the aim of going beyond real ones, and solving the problems emerged from common life. This article intends to remark that theorical conceptions of society frequently have an ‘eutopian’ counterpart, that means, a very best physical or geographical location. It can be appreciated precisely in the Ancient Greek world. In order to approach to this subject, we will depart from the usual version in the pólis of the Golden Age given (...) by Hesiod, and we will put it together with the eutopian reformation proposed by Pythagoreans and the ‘conservative’ presentation found in Aristotle’s Politics and Ethics.

Uno de los más famosos legados que recibe el pensamiento moderno proveniente del estoicismo antiguo es la concepción del cosmopolitismo, a pesar de lo cual la idea original estoica cuenta con nuevos enfoques y corrientes. La filósofa e importante clasicista Martha Nussbaum ha establecido en la actualidad una de las teorías más destacables teniendo en cuenta un punto de vista explícitamente estoico. En este artículo pretendo analizar, por un lado la exposición que Nussbaum ha hecho de la ciudadanía mundial, así (...) como las discusiones críticas ulteriores que su teoría del cosmopolitismo ha originado.

Identity itself has become complex and fragmented in our age, and in this sense, perhaps conventional categories as cosmopolitanism therefore no longer suit us very well. Conceptualizing the intellectual landscape between reactionary localism and vapid universalism, is where the debate in ethical cosmopolitanism has landed today. Although it shows no real sign of theoretical resolving or slowing, cosmopolitan theory has taken more explicitly new direction connected with the project associated with Martha Nussbaum’s thought. I propose to deal in this paper (...) her ultimately and re-articulated cosmopolitan ideas. (shrink)

As Socrates argues in Cratylus, although different name-makers or name-designers (Greeks and barbarians) do not embody the name in the same syllables it must not be forgotten that they attempt to reproduce the same ideal (t´ypos). Could also Greek and barbarian names of gods, made of different letters and syllables, reproduce the same t´ypos? If one takes seriously Herodotus’ onomatological inquiry in his Egyptian lógos (The Histories II 50), one may find the optimum way to understand the scope of Plato’s (...) dialectical ‘games’ between the three speakers in Cratylus (Socrates, Hermogenes and Cratylus) and, more precisely, their «theological» implications.

Aristotle says that only humans can speak and the speech capability is a proper criterion of humanity. Speech is also designated by Aristotle to indicate the right and the wrong. He finishes by saying that it is partnership in these things that makes a city. Ultimately a human being who is not in a polis, would not really be a human being at all? Would this human being then be no more human than a statue with a human form?

La entidad NO-DO cumplió un papel de primer orden en la interpretación del territorio español (paisajes, costumbres, tradiciones, monumentos, etc.), a través de sus producciones cinematográficas durante el franquismo y la Transición. Este artículo analiza la imagen y la identidad que se forjó del legado artístico y monumental de Murcia, desde la metodología de los estudios visuales. Las conclusiones demuestran que si bien la catedral y la vista urbana de Murcia configuraron la imagen-marca de la ciudad, como ya había sucedido (...) en el siglo XIX, los escultores Salzillo y Planes fueron los principales representantes del arte murciano en el cine oficial franquista.

Populism has become one of the most worrying political phenomena, and given its complexity, one of the most controversial and debated today in social sciences. This article deconstructs and compares the discourses of the Spanish parties that are generally classified as populist —the left-leaning Podemos, the right-wing Vox and the Basque and Catalan secessionist parties EH Bildu, Esquerra Republicana de Catalunya and Junts per Catalunya— according to five dimensions of populism: i) antagonism, ii) morality, iii) idealised construction of society, iv) (...) exaltation of popular sovereignty, and v) personalist leadership. This article shows that, despite significant ideological and programmatic differences, all these parties share many discursive features and a similar way of articulating their communications, interpreting social and political dynamics, as well as instrumentalizing crises to build new political identities.

El propósito de este estudio es dilucidar algunos de los rasgos distintivos de la concepción del ser humano que mantiene Jürgen Habermas y sus implicaciones en la teoría de la acción comunicativa. De este modo, se trata de mostrar que la antropología habermasiana se singulariza por adoptar una perspectiva naturalista y darwinista. En la primera parte, se analiza el legado epistemológico de Darwin como un programa de investigación y se contrastan los estudios de Habermas sobre antropología biológica con las últimas (...) investigaciones en genética y paleontología. En la segunda parte, se presenta la propuesta de Habermas de afrontar un dualismo epistemológico mediante un naturalismo débil noreduccionista, como crítica de la metafísica moderna y estructurador de un nuevo realismo.

El sentido que la educación liberal posee para Michael Oakeshott se concentra en que ésta consiste en un aprendizaje de las disciplinas humanísticas y científicas. Dichas disciplinas se muestran valiosas ya que tienen la virtud de desarrollar el intelecto y la sensibilidad humanas y porque aportan, además, una comprensión operativa de lo que son nuestro yo, la sociedad, la naturaleza y la cultura. No obstante, como también es sabido, los fines que la educación liberal se propone pecan un tanto de (...) idealistas, de manera especial cuando se insiste, como muchos han hecho desde los antiguos griegos, en que dicha educación es un fin en sí misma. En parte, lo demuestra la presencia permanente en nuestra cultura occidental de unos espacios de aprendizaje (‘schola’) que se conciben como si estuvieran separados del aquí y ahora en que transcurre la vida cotidiana.

Using the lens of conceptual history, we analyze the evolution of the term digital commons since it first came to be publicly used. In particular, we track down how the meaning of the term digital commons was influenced after its emergence by a new modulation of the term commons developed from neo-Marxist coordinates. Exploring the way in which this neo-Marxist way of thinking the commons emerged after the economic crisis of 2008 thanks to the discursive interventions of a couple of (...) authors more or less linked to the Midnight Notes Collective, we subsequently analyze the degree of penetration of this new conception of the commons in the realm of the digital commons. As we conclude, the disparate reception of this conception on the way different authors think and theorize the digital commons confirms the essentially contested nature of this particular concept.

El propósito de Levinas coincide con el intento moderno de recuperación de la verdad y del sentido aunque en una dirección y contenidos distintos. Si en Hegel la Aufhebung tendía a la Totalidad y lo Mismo , para Husserl será esencial la apertura de Mundo que tiene lugar ya en la experiencia de conciencia del ego trascendental, mientras que Heidegger, por su parte, primará la pregunta por el Ser. El intento de Levinas, en cambio, no será recomponer la relación entre (...) el yo, por un lado, y el mundo, lo absoluto, las cosas o el ser, por el otro, sino la recuperación de la relación entre yo-y-otro. No es un simple cambio en la dirección o en el contenido del sentido de la reflexión filosófica, sino un intento serio de encontrar una nueva significación, «otra manera que ser» que no termine siendo otro proyecto más de integración y síntesis. Lo que propone Levinas es una auténtica salida para la que traza el itinerario que va del ser al otro, recurriendo sencillamente a la experiencia que cotidianamente se nos impone a cada uno de nosotros con un peso incontestable, a saber: la presencia de las diferencias, de lo asimétrico, en definitiva, la manifestación del otro en tanto que otro. Es esta experiencia heterónoma ordinaria, esta vivencia diaria de la alteridad como dato primordial del fenómeno de la intersubjetividad el ámbito que ha intentado explorar nuestro autor. ¿Acaso es esta responsabilidad así sentida conjugable con una experiencia filosófica universal? ¿La responsabilidad puede llevarse hasta el límite de la substitución por el otro, hasta la de-posición del Yo sin identidad? ¿Qué tipo de relación puede darse con algo absolutamente asimétrico, exterior, previo e irreductible? ¿De dónde viene esa asignación apremiante de responsabilidad que llega hasta arrojarme en la obsesión y el asedio? ¿Cómo puede ser éticamente plausible un mandato tan traumatizante y violento que termina por convertir al sujeto en rehén, sustituido ya por los otros? ¿Es posible conciliar la libertad y la autónoma decisión del sujeto con una consideración de la subjetividad como «heme aquí», absoluta pasividad expuesta a los otros y vulnerabilidad de una piel que se ofrece al ultraje y la herida?. En definitiva: ¿es la subjetividad algo de lo que partimos o a lo que llegamos? (shrink)
