A general mathematical framework, based on countable partitions of Natural Numbers [1], is presented, that allows to provide a Semantics to propositional languages. It has the particularity of allowing both the valuations and the interpretation Sets for the connectives to discriminate complexity of the formulas. This allows different adequacy criteria to be used to assess formulas associated with the same connective, but that differ in their complexity. The presented method can be adapted potentially infinite number of connectives and truth values, (...) therefore, it can be considered a general framework to provide semantics to several of the known logic systems (eg, LC, L3 LP, FDE). The presented semantics allow to converge to different standard semantics if the separation complexity procedure is annulled. Therefore, it can be understood as a framework that allows greater precision (in complexity terms) with respect to formula satisfaction. Naturally, because of how it is built, it can be incorporated into non-deterministic semantics. The presented procedure also allows generating valuations that grant a different truth value to each formula of propositional language. As a positive side effect, our method allows a constructive proof of the equipotence between N and N^n for all Natural n. (shrink)

Some partitions of Natural Number set are built through recursive processesgenerating in this manner countable examples of countable and disjoint sets whose unionis a set also countable. This process is constructive, so the Axiom of choice is not used.We provide a PC program that generates one of these special partitions and shows howto generate infinite of them. This line of reasoning can have multiple applications in Settheory and Model theory. We proved that the number of ways to make these partitionsof (...) natural numbers is not countable, there are more of these partitions (named doublycountable) than natural numbers. For each natural number greater than 1, we show aneffective procedure that generates these partitions -/- . (shrink)

Software vulnerabilities are the root cause for a multitude of security problems in computer systems. Owing to their efficiency and tight control over low-level system resources, the C and C++ programming languages are extensively used for a myriad of purposes, from implementing operating system kernels to user-space applications. However, insufficient or improper memory management frequently leads to invalid memory accesses, eventually resulting in memory corruption vulnerabilities. These vulnerabilities are used as a foothold for elaborated attacks that bypass existing defense methods. (...) In this paper, we summarise the main memory safety violation types (i.e. memory errors), and analyse how they are exploited by attackers and the main mitigation methods proposed in the research community. We further systematise the most relevant techniques with regards to memory corruption identification in current programs. (shrink)

Se analiza la construcción social del Campo de Tiro Militar de El Teleno como reserva natural a partir de la retórica auspiciada por el “giro ambientalista” del Ministerio de Defensa. Ante la conflictividad existente en Maragatería, esta estrategia de contención deviene en una sublimación ideológica: la posibilidad de la preservación (natural) viene dada por la reproducción necesaria de la destrucción (humana). Por su parte, las estrategias de resistencia han adoptado formas diferentes. Entre ellas, la construcción social del Teleno como patrimonio (...) cultural socava la estrategia de sublimación del C.M.T. como “paraíso natural”, mostrando la fuerte presencia humana previa en la zona. Ambas metanarrativas se han convertido en el pilar fundamental alrededor del cual se organizan las luchas simbólicas entre instituciones y activistas, lo que representa un cambio fundamental al dejar fuera a las personas y las relaciones inmanentes de las comunidades con el bosque. En ambos discursos metaculturales, se reproduce la separación entre naturaleza y cultura tan característica de la modernidad. (shrink)

Estudiamos varios conceptos clave en la obra del franciscano Fray Juan de Pineda, especialmente el concepto de ‘gracia justificante’, que se opone teológicamente a las ideas luteranas pero que desarrolla un pensamiento erasmista, afín a Fray Luis de Granada, a Francisco de Osuna y a Bartolomé de Las Casas. Estudiamos también su concepto de ‘lavacro’, procedente de San Pablo y su relación con la interpretación del Padre Nuestro, lo que apunta de lleno a la polémica doctrinal entre Carranza y (...) Melchor Cano. Finalmente hacemos ver la identidad de planteamientos erasmistas con el Lazarillo de Tormes, cuya geografía (Salamanca, Escalona, Maqueda y Almorox) coincide con el área de predicación de Fray Juan de Pineda a partir de 1544. Dada la coincidencia léxica, biográfica, doctrinal y de estilo entre el Lazarillo y la obra de Fray Juan de Pineda, sostenemos que esta novela picaresca corresponde a la intención reformadora del pensamiento erasmista franciscano del siglo XVI.

Knowledge about maize varieties is the key to rural households' survival in native Mexico. Native peoples relate to nature in particular ways and they play a crucial role in maintaining biodiversity. This paper discusses the relationship between native women's accumulated knowledge on maize varieties and the laboratory analysis of the species that they manage. Fieldwork was conducted in an Otomí community, San Pablo Arriba, located in the state of Mexico.

This paper presents and defends a way to add a transparent truth predicate to classical logic, such that and A are everywhere intersubstitutable, where all T-biconditionals hold, and where truth can be made compositional. A key feature of our framework, called STTT (for Strict-Tolerant Transparent Truth), is that it supports a non-transitive relation of consequence. At the same time, it can be seen that the only failures of transitivity STTT allows for arise in paradoxical cases.

This paper aims to offer an account of affective experiences within Predictive Processing, a novel framework that considers the brain to be a dynamical, hierarchical, Bayesian hypothesis-testing mechanism. We begin by outlining a set of common features of affective experiences that a PP-theory should aim to explain: feelings are conscious, they have valence, they motivate behaviour, and they are intentional states with particular and formal objects. We then review existing theories of affective experiences within Predictive Processing and delineate two families (...) of theories: Interoceptive Inference Theories and Error Dynamics Theories. We highlight the strengths and shortcomings of each family of theories and develop a synthesis: the Affective Inference Theory. Affective Inference Theory claims that valence corresponds to the expected rate of prediction error reduction. In turn, the particular object of a feeling is the object predicted to be the most likely cause of expected changes in prediction error rate, and the formal object of a feeling is a predictive model of the expected changes in prediction error rate caused by a given particular object. Finally, our theory shows how affective experiences bias action selection, directing the organism towards allostasis and towards optimal levels of uncertainty in order to minimise prediction error over time.

This paper investigates ontological dimensions of the blockchain by asking what kind of socio-technical object bitcoin is. It discusses both blockchain's political qualities and the political forms enabled by its emergence. It first observes recent approaches to the ontology of money and the political qualities of the ledgers used by the current fractional reserve banking model. It then directs the same questions at blockchain technology. The paper discusses an ontology proposed by Ole Bjerg and argues in favour of a mixed-ontology (...) approach to blockchains. It then questions the political qualities of the distributed ledger as a digital object and highlights the apparent absence of authority figures in the model. Finally, it argues that the political ontology of the blockchain can be framed as the displacement of authority from institutional actors into instrumental control of trust, in a dynamically distributed environment.

A commitment to ‘making’—creating or producing things—can shape scientific and technological fields in important ways. This article demonstrates this by exploring synthetic biology, a field committed to making use of advanced techniques from molecular biology in order to make with living matter. I describe and analyse how this field’s ‘drive to make’ shapes its organisational, methodological, epistemological, and ontological character. Synthetic biologists’ ambition to make helps determine how their field demarcates itself, sets appropriate methods and practices, construes the purpose and (...) character of knowledge, and views the things of the living world. Using empirical data from extensive ethnographic and interview-based research, I discuss the importance of seemingly simple and unimportant commitments—in this case, a focus on the making of things rather than the production of knowledge claims. I conclude by examining the ramifications of this line of research for studies of science and technology. (shrink)

En la modernidad tradicional la realidad se presenta desde una mathesis universalis que la explica y le confiere unos contornos fijos y claros desde los cuales es posible construir todo el edificio de la ciencia natural que lo explica. Así, el mundo del hombre se observará desde las leyes universales que rigen todo comportamiento humano en sociedad. Para Nietzsche, por el contrario, el mundo sólo encuentra su fundamento en el devenir de configuraciones de fuerzas que no se rigen por ninguna (...) ley previa más allá de su propia relación. Igualmente, en Baltasar Gracián, es ampliamente apoyada la tesis de que el aragonés propone una «nihilización» del mundo que coloca su fundamento fuera, en fuga. Nos proponemos analizar las reflexiones de Baltasar Gracián y Friedrich Nietzsche de acuerdo a las cuales el mundo aparece desde su «inmundicia» y falta de fundamento en contra de esa visión moderna que busca someter al mundo a unas leyes fijas y universales. Sin embargo y, al mismo tiempo, queremos mostrar cómo esta visión no conduce a un nihilismo resignado, sino que, por el contrario, impone al hombre la responsabilidad de, aceptando este desfondamiento del mundo, hacer de él algo que merezca la pena ser vivido.

The modern concept of reason called one of the fundamental tenets of Christianity into question: the universal value of the salvation brought to all humanity by Jesus. From a modern point of view, it is not possible for a historic and contingent event, such as the death of Jesus, to bear universal meaning for men of all times. In this article I aim to show how René Girard’s anthropological hypothesis offers an alternative answer to the seemingly impossible universale concretum.

En su conocida monografía sobre Richard Rorty, publicada en 2008, el sociólogo de la filosofía Neill Gross, formuló, con la intención de corregir los modelos de «sociofilosofía» propuestos por Randall Collins y Pierre Bourdieu, una teoría acerca del «autoconcepto» que los pensadores elaboran sobre sí mismos. Esa teoría, bastante influyente, se sustenta entre otras cosas en lo que puede considerarse una errónea lectura de la obra de Pierre Bourdieu. En primer lugar se exponen los principios que guían la teoría de (...) Gross y su aplicación en la monografía sobre Rorty. En segundo lugar se pondrá en duda la tesis de Gross pretendiendo rebasar con su teoría el modelo explicativo ofrecido por Bourdieu en el ámbito de la sociología de la filosofía, mostrando las distorsiones introducidas en su lectura del sociólogo francés. Finalmente, se sugerirá una reinterpretación de la trayectoria de Rorty apoyándose en la teoría bourdieusiana del habitus y prescindiendo de la noción de «autoconcepto intelectual» introducida por Gross.

There is vast evidence that accounts for the association between entrepreneurial orientation and the probability of starting a business. However, there are not many studies that test how psychological factors moderate this relationship. A variable that has been little studied in this relationship is Grit. Grit is considered a personality trait defined as perseverance and passion for long-term goals. Grit considers two sub-dimensions, one linked to the consistency of interests and the other linked to perseverance in the effort. The objective (...) of this article is to analyze the moderating role that both sub-dimensions of grit plays in the relationship between EO and PSB, considering its interaction with sociodemographic variables such as age, gender, and culture. This cross-sectional study has a sample of 1,761 participants, active workers. The EO scale and a Grit Scale were applied. In addition, participants were asked, based on their perception, how likely they were to start their own business within the next 5 years. A simple moderation analysis was considered to test the moderating role of grit in the relationship between EO and PSB. Subsequently, a double moderation analysis was carried out in order to identify which sociodemographic variables moderate the moderating effect of grit on the relationship in question. The results show that only the Grit-Passion component of grit moderates the relationship between EO and PSB. Regarding the sociodemographic variables, neither age, culture, nor gender showed a moderating effect on the moderation exercised by Grit-Passion in the relationship between OE and PSB. The results are discussed in terms of psychological capital, particularly with an emphasis on explaining why only the Grit-Passion shows a moderating effect on the relationship between EO and PSB, in detriment of Grit-Perseverance. In addition, the power of grit in the field of entrepreneurship is discussed, considering that its moderating effect is transversal to variations in age, gender and culture, as well as its relevance when considering interventions and pedagogical models in the field of entrepreneurship.

The present paper explores the phenomenology of disorientation and its relationship with self-consciousness. Section 1 discusses previous literature on the links between self-location and self-consciousness and proposes a distinction between minimal self-location and integrated self-location. The double aim of the paper is to use this distinction to deepen our understanding of spatial disorientation, and to use the phenomenology of disorientation to elucidate the role that integrated self-location plays in shaping self-consciousness. Section 2 starts by looking at the experience of being (...) “turned around”, which is a common experience of disorientation. This analysis leads to the conclusion that integrated self-location is transmodal and depends on all three egocentric axes, and that disorientation destabilizes this integrated self-location. Section 3 explores a corpus of reports of disorientation episodes and highlights four key characteristics of these experiences and their links to self-consciousness, focusing on the transformations in both the lived body and the experience of space. The central thesis of this paper is that during disorientation a destabilization of integrated self-location results in a diminished form of self-consciousness. (shrink)

Tratamos, en este trabajo, de un curso de Heidegger de su primera época de Friburgo, a saber Phänomenologie der Anschauung und des Ausdrucks. Theorie der Philosophischen Begriffsbildung, del semestre de invierno 1919/20. Se deciden en dicha época, para Heidegger, cuestiones esenciales en punto a qué sea fenomenología y cuál haya de ser su método. En la primera parte de mi artículo presento ciertos conceptos clave de esta fenomenología de la intuición y de la expresión como son los conceptos de palidecimiento (...) o Verblassung del significado, así como los relativos al movimiento que se presenta como su contrapunto, a saber, la llamada Phänomenologische Destruktion, evidenciando su relación con el hoy célebre proceder «formalmente indicativo», y que tiene en la llamada Phänomenologische Diiudication su punto culminante. Dedicaré una segunda parte a la brillante aplicación de la «destrucción fenomenológica» al concepto de «historia» y a sus diversos sentidos, haciendo uso de las célebres categorías hermenéuticas (Gehaltsinn, Vollzugsinn, Bezugsinn) en las que se moverá el uso de la indicación formal. Veremos así a la destrucción fenomenológica a la obra. (shrink)

Con ocasión de este volumen conmemorativo dedicado a Ricardo Sánchez Ortiz de Urbina, recordamos brevemente cómo se fraguó el encuentro de este con Marc Richir, que daría lugar, más adelante, a un genuino diálogo filosófico.

Presentamos en estas líneas el contenido de este número especial dedicado a la literatura, al arte y a la filosofía. Desde una perspectiva mayoritariamente fenomenológica, los trabajos que aquí presentamos insisten en la enigmática independencia (propia de una transcendencia inmanente) de los «objetos» que despuntan y dan consistencia a las actividades literarias y artísticas.

Este artículo sienta los preliminares de un trabajo más sistemático de análisis fenomenológico de la greguería en particular y algunos aspectos de la obra de Ramón Gómez de la Serna en general. Nos basaremos, en estas páginas, en dos prólogos en los que Ramón reflexiona sobre su propio quehacer: el prólogo a la edición de Greguerías de 1960 y el prólogo a las Novelas de nebulosa. Insistiremos en los aspectos de la diacronía entre aquello a lo que apunta la greguería (...) y la greguería misma en su parte expresiva. Ello nos llevará a pensar la experiencia en términos de registros de temporalización (y de fenomenalización). Insistimos por último en la ruptura imprepensable que toda greguería produce en el campo de las posibilidades preestablecidas, y en cómo la experiencia de la greguería, tal y como la presenta Ramón, indica en la dirección de una suerte de realismo fenomenológico no-objetual.

PurposeAnomic feelings are predicted to play a moderating role in the relationship between organisational justice perceptions and the citizenship use of the organisation's internet access, or cybercivism. The purpose of this paper is to hypothesise that, just as AFs are supported in prior research as able to intensify the negative effects of organisational justice on cyberloafing, they will also intensify the positive effects of OJ on cybercivism.Design/methodology/approachData were collected from 270 of the 1,547 respondents at a public university.FindingsExcept in the (...) case of procedural justice, the results support that AF act as a moderator of the OJ‐cybercivism link because, among employees with comparatively less AF, the perceptions of the OJ under study had a stronger impact on cybercivism.Research limitations/implicationsTo generalise from a convenience sample of 17 per cent to the entire University is unfeasible, let alone the “public sector” as a whole for a whole culture/country. Therefore, the paper only aims to be an early exploration of actual phenomenon, and to provide new insights necessary to understand the impact of pervasive new media and information and communication technologies on individual behaviour in virtual work settings.Practical implicationsThe findings contribute to an improved understanding of the influence of OJ on cybercivism. As a moderator, anomia is supported in our sample as one of the key “controllers” of the OJ predictions on cybercivism and sets a new scenario in seeking electronic business effectiveness. By encouraging convincing values and equity in the workplace, organisational management seems be on the right path to create the proper context for cybercivism to occur.Originality/valueEmployee AFs are shown to be a moderator in the relationship between OJ and cybercivism. This is the first empirical test of this interaction. (shrink)

According to a popular view, the creation of social reality requires language: social institutions emerge when we successfully declare them into existence. Making language central to institutions deprives the non-human of any claim to a social reality. This is particularly problematic in the light of mounting research showing many animals have social institutions even in the absence of language. In this paper, I will offer an alternative view. I will employ a concept –enacted representation– from the distributed cognition framework of (...) cognitive science to develop a social ontology that does not take language as a requirement to create social institutions.

La reflexión sobre el tiempo en la fenomenología sartreana ha estado presente desde sus inicios, pero no ha dado lugar a una sola teoría del tiempo, sino que ha pasado por tres momentos diferentes, en los cuales han surgido por cada momento una teoría distinta. Así, en relación al primer momento encontramos una teoría instantaneísta, en relación al segundo, una teoría de la temporalidad, y en relación al tercero, una teoría de la historialidad. Por esta razón, el objetivo principal de (...) este trabajo es explicitar los desarrollos intrínsecos de cada teoría para, de esta forma, mostrar cómo la fenomenología sartreana contribuye al esclarecimiento de uno de los temas más importantes para filosofía, y en especial para la fenomenología, como es el tiempo.
