The concept of polarity is pervasive in natural language. It relates syntax, semantics and pragmatics narrowly, Semantics: an international handbook of natural language meaning, De Gruyter Mouton, Berlin, 2011; Israel in The grammar of polarity: pragmatics, sensitivity, and the logic of scales, Cambridge studies in linguistics, Cambridge University Press, Cambridge, 2014), it refers to items of many syntactic categories such as nouns, verbs and adverbs. Neutral polarity items appear in affirmative and negative sentences, negative polarity items cannot appear in affirmative (...) sentences, and positive polarity items cannot appear in negative sentences. A way of reasoning in Natural Language is through Natural Logic. This logic is based on the concept of polarity in order to make the meaning of a sentence weaker o stronger without changing its truth value. There exist many proposals to compute polarity in the Natural Logic context, the most widely known are the ones by: van Benthem, Sánchez-Valencia, Dowty, and van Eijck, 6th international Tbilisi symposium on logic, language, and computation, Batumi, Georgia, Springer, 2007). If Natural Logic is going to be used, as an inferential mechanism between text fragments, in Natural Language Processing applications such as text summarization, question answering, and information extraction, it is a priority to know what the existing relationship among the aforementioned algorithms is; for example, to implement the most general. We show in this paper the equivalence among the analyzed algorithms, filling a gap in Natural Logic research, particularly in computing polarity, and the soundness of their algorithms. (shrink)

Resumen. El siguiente artículo conceptual muestra un análisis de la literatura con respecto a larelación entre la Efectividad Organizacional y los planes de Remuneración a los empleados sobretodo en su perspectiva variable. Se encontró la existencia de esta relación durante el análisis dediversas investigaciones en contextos diferentes al mexicano, por ello se propone profundizar más enel estudio de la misma en un contexto de empresas mexicanas debido a los pocos estudiosencontrados a este respecto.Palabras claves. Remuneración variable, efectividad organizacional, bono de (...) productividad, bonopor cumplimiento de objetivos, premios a grupos y equipos, remuneración por méritos, remuneraciónpor competencias.. The follow conceptual article shows an analysis of the literature about the relationshipbetween the organizational effectiveness and the employee’s remuneration plans, especially in itsvariable view. It founded the existence of this relationship during the analysis of several studies indifferent contexts from the Mexican´s, therefore it propose to investigate more about the study of thesame relationship in Mexican companies due to the few studies founded in this regard.Keywords. Variable remuneration, organizational effectiveness, productivity bonus, individualincentive plans, team/group incentive plans, merit pay, competency based structure. (shrink)

The purpose of this paper is to analyse the Spanish mobile phone industry to determine how mobile phone companies and certain institutions can improve protection for children who use mobile phones. We carried out a multivariate statistical analysis using anonymous primary data from mobile phone companies, and institutions and associations that protect children, to compare these stakeholders’ opinions and to put forward solutions. We proved that, even though some European countries have made an effort to provide safer ICT services, all (...) stakeholders still need to cooperate and agree on solutions to the commercial problems associated with children using mobile phones. This can be done by signing codes of conduct. We found that even though some companies implement measures to protect children from accessing harmful content via their mobile phones, they do so for reasons of legal and not social responsibility.

Bidirectional trans‐synaptic signaling is essential for the formation, maturation, and plasticity of synaptic connections. Synaptic cell adhesion molecules (CAMs) are prime drivers in shaping the identities of trans‐synaptic signaling pathways. A series of recent studies provide evidence that diverse presynaptic cell adhesion proteins dictate the regulation of specific synaptic properties in postsynaptic neurons. Focusing on mammalian synaptic CAMs, this article outlines several exemplary cases supporting this notion and highlights how these trans‐synaptic signaling pathways collectively contribute to the specificity and diversity (...) of neural circuit architecture.

El sistema filosófico de Radbruch es, a mi juicio, tenso y complejo, pero no contradictorio. La seguridad pugna con la justicia; el juez sometido a la ley pugna con el ethos del juez que es la justicia; el Derecho positivo es incompatible con el Derecho Natural; el relativismo no admite una fe ciega en los valores; el Derecho Natural está en contra, incluso, de la naturaleza de la cosa, etc. Ante esto lo más inteligente es un relativismo con “vocación de (...) objetividad”. Un relativismo que desde la tolerancia y la libertad fundamenta racionalmente el Derecho, cuyo deber moral de obediencia está en “la seguridad”. Pero hay circunstancias extremadamente inhumanas y vergonzosas, en las que las leyes pueden ser en tal grado injustas y nocivas, que ni la más elemental “seguridad” podría justificarlas, pues hay un auténtico deber moral de negarles validez. En este caso el deber moral de desobediencia se basa en la “justicia”, es decir, en unos principios que son más fuertes que toda disposición jurídica y que se llaman Derecho Natural. No veo contradicción alguna en que en circunstancias normales centre el fundamento moral de validez de las normas positivas en el valor seguridad, y en circunstancias excepcionales sea la justicia más elemental (el Derecho natural) la que niegue validez y obediencia a las leyes extremadamente inhumanas. No veo, pues, contradicción en el trayecto que recorre desde el relativismo al iusnaturalismo, pasando, diría yo, por la llamada “naturaleza de la cosa”. (shrink)

Resumen La sociología de lo religioso se encarga de buscar los signos y los símbolos que se encuentran en constante pulsión en la realidad social. Su tarea consiste en explicar las diversas manifestaciones y dinámicas del fenómeno religioso que se expresan a través de las prácticas sociales y cómo dicho fenómeno está participando en la construcción y en la transformación de los distintos discursos . La religión, el lenguaje y la visión de mundo no escapan a los conflictos políticos, sociales (...) y culturales. En ese sentido proponemos un análisis del discurso profético del movimiento neo-zapatista y sus características globales en relación a la construcción de una sociedad más democrática, justa e igualitaria. El Ejército Zapatista de Liberación Nacional es un referente importante dentro de los movimientos anti-sistémicos no sólo por sus planteamientos sociales y políticos sino por sus referencias simbólicas, utópicas, mesiánicas y milenaristas de ahí que sea necesario realizar una hermenéutica profunda de sus imágenes proféticas: lenguaje y performance . Palabras clave: modernidad; consciencia planetaria; emancipación; religiosidad Resumo A sociologia da Religião se encarrega de buscar os signos e símbolos que se encontram em constante pulsão na realidade social.

The primary task of the above consists primarily of explaining diverse and dynamic manifestations of religious phenomena which are expressed through social practices and how such phenomena participate in the construction and transformation of the different political and cultural discourses. Religion, language and world-vision do not escape from political, social and cultural conflicts. It is in this sense that we propose an analysis of the global neo-Zapatista prophetic discourse and its global characteristics in regards to the construction of a more democratic society, righteous and egalitarian. The Zapatista Army of National Liberation is an important referring within the anti-systemic movements not only its social and political expositions but also their symbolic, utopian, messianic and millenaries references; it is necessary to realize a deep hermeneutic of his prophetic images: language and performance. Key words : modernity, global consciousness, emancipation, religiousness. (shrink)

The US poultry industry based on flexible accumulation has been advanced as the model of agro-industrial development for agrifood globalization. Similarly, Mexico has been presented as a noteworthy example of the negative effects of neoliberal restructuring associated with the globalization project. In this paper we use both of these assertions as points of departure to guide an investigation of the case of the restructuring of the Mexican poultry industry. Informed by a commodity systems analysis, archival data and key informant interviews (...) are used to generate an overview of the history of the poultry industry in Mexico. A sociology of agrifood theoretical framework informed by regimes theory is employed to analyze the events of the case. We conclude that neoregulation related to the IMF and NAFTA restructuring in Mexico facilitated the diffusion of the US model of poultry production. (shrink)

The Post-genomic Era includes features both from a methodological and epistemic point of view and from an ontological perspective. Firstly, it incorporates new methods of high-throughput sequencing of DNA and RNA, and the development of complete genomes that allow a precise reference of the molecular results obtained. In addition, from an ontological perspective, the centre of gravity of the molecular processes is placed on the expression of genes, and the way in which such expression is regulated; these features turn the (...) attention towards the study of Gene Regulatory Networks, and in particular to the role of RNA. This new molecular-biological perspective based on new methodologies and approaches is affecting the existing Molecular Genetics Theory including the definition of gen and Central Dogma of Molecular Biology. An important philosophical challenges posed by this new situation is the question whether there is a sophistication of the present theory or a New Theory of Molecular Genetics and whether there is an incommensurability between this theory and the accepted theory. In this work we evaluate these changes in the light of Kuhn’s theory of scientific revolution in order to propose an alternative between a moderate and a strong view. According to the moderate one, the Post-genomic changes do not properly involve a paradigm shift or, if they do, they constitute a minor revolution. The strong view considers that, the anomalies disclosed in the Molecular Genetics Theory at conceptual and methodological level and the Post-genomic changes they lead to suppose a scientific paradigm shift.

El siguiente ensayo rastrea las reflexiones de Friedrich Hölderlin en torno a lo mítico. El argumento, expuesto una y otra vez en su correspondencia, sus ensayos y poemas, continuamente refinado y corregido, es que, expresado en lenguaje poético, el mito permite recuperar una visión del mundo fragmentada con el ímpetu analítico finisecular. El concepto de lo mítico de Hölderlin no solo está profundamente influido por el contexto histórico e intelectual en los lindes del Frühromantik, la filosofía de Fichte, la estética (...) de Schiller y la Revoluciónfrancesa como notas principales, sino también por las experiencias de la niñez, las lecturas de los colegios conventuales o los encuentros en Tubinga o Fráncfort. Finalmente, el texto muestra cómo estas indagaciones cristalizan en distintos motivos de su producción lírica. (shrink)

En el artículo se describe el tránsito filosófico-existencial de Tula, protagonista de la novela La tía Tula de Miguel de Unamuno, por los tres estadios vitales del filósofo danés Søren Kierkegaard. A lo largo del texto, se muestra que las dudas existenciales que se plantea la protagonista son extensivas para todo el género humano. Además, el texto busca mostrar cómo la narrativa del pensador español está plagada de reflexiones filosóficas y está fuertemente influida por el existencialismo cristiano de Kierkegaard. Debatiéndose (...) entre la fe y la razón, Tula transita por los estadios tomando decisiones que entrañan sufrimiento. En esta novela, se plasman los afanes del ser humano por la perpetuación, inmortalidad y salvación frente al rostro descarnado de la nada. (shrink)

The use of images in education has received little attention despite the dual role of images in school textbooks, one aimed at the acquisition of knowledge and the other at the transmission of attitudes, values and norms, that constitute a valuable source of historical, educational and communicative research. We will study, through the analysis of content, the characteristics of the catechisms, the legislation of the time related to the publication of school textbooks, the presence of images, types, the didactic function (...) and the transmission of social models and ideology. The research suggests that the images of school catechisms are not simply reflections of a reality that facilitates the learning of the contents taught in schools, but that they also become an effective tool in the transformation of the values and ideological thinking of the social context in which they are produced.

Both Franz Brentano and Edmund Husserl addressed sound while trying to explain the inner consciousness of time and gave to it the status of a supporting example. Although their inquiries were not aimed at clarifying in detail the nature of the auditory experience or sounds themselves, they made some interesting observations that can contribute to the current philosophical discussion on sounds. On the other hand, in analytic philosophy, while inquiring the nature of sounds, their location, auditory experience or the audible (...) qualities and so on, the representatives of that trend of thought have remained silent about the depiction of sound and the auditory phenomena in the phenomenological tradition. The paper’s intention is to relate both endeavours, yet the perspective carried out is that of analytic philosophy and, thus, I pay special attention to conceptual analysis as a methodological framework. In this sense, I first explain what sound ontology is in the context of analytic philosophy and the views that it encompasses— namely, the Property View (PV), the Wave View (WV) and the Event View (EV)—. Secondly, I address the problems it entails, emphasising that of sound individuation. In a third section, I propose the possibly controversial conjunction of a “Brentano-Husserl Analysis of the Consciousness of Time” (for short “Brentano-Husserl analysis”) and outline the commonalities of both authors, without ignoring its discrepancies. My main focus is Husserl’s 1905 Vorlesungen zur Phänomenologie des Inneren Zeitbewusstseins. While addressing the Brentano-Husserl analysis, I elaborate on the problem of temporal and spatial extension (Raumlichkeit and Zeitlichkeit, respectively) of both consciousness and sound. Such comparison is a key one, since after these two developments, one can notice some theoretical movements concerning the shift of attention from sounds to the unity of consciousness, and how they mirror each other. After examining the controversial claims concerning the temporal and spatial extension of both consciousness and sound, I argue in the concluding paragraphs that while considering the accounts of sound ontology, the Brentano-Husserl analysis would probably endorse a Property View and that this could have interesting consequences for the issue of Sound Individuation.
