In this work it is presented a methodology for the development of a pattern recognition system using classification methods as discriminant analysis and artificial neural networks. In this methodology, the statistical analysis is contemplated, with the purpose of retaining the observations and the important characteristics that can produce an appropriate classification, and allows, as well, to detect outliers’ observations, multicolinearity between variables, among other things. Chlorophyll a fluorescence OJIP signals measured from Pisum sativum leaves belonging to different drought stress resistance (...) groups are correctly classified using the proposed here methodology.

In two experiments on analogical hypothesis generation, we factorially manipulated the presence of domain and object similarities between a base situation and a target phenomenon, and assessed their effects on the transfer of the source’s explanatory structure before and after an indication to use the base analog as a source for analogical explanations. The absence of any kind of surface similarity led to very low rates of spontaneous transfer. In both experiments, however, either kind of surface similarity sufficed to enhance (...) the spontaneous transfer of the base explanation during the formulation of plausible hypotheses for the target. The transfer advantage of object and domain similarity cannot be attributed to the effect of these variables on post-access processes, since experimental conditions did not differ with regard to the ability to transfer the base explanation upon explicit request. The effect of domain similarity on spontaneous analogical explanation constitutes a relevant finding, especially given the lack of attention received by this dimension of similarity in behavioural studies and computer simulations of analogical retrieval.

Alejandro de Hales, maestro franciscano de la Universidad de París en la primera mitad del siglo XIII, no es un autor que haya sido estudiado con demasiada frecuencia en las últimas décadas. Sin embargo, sus obras, entre las que se destaca su voluminosa Summa Theologica, revelan no solamente profundidad especulativa, sino también una inteligente recepción de las fuentes clásicas, patrísticas y medievales. En la Summa, dedica la Inquisitio tertia a tratar las especies de pecados actuales, y es en la cuestión (...) 1 de la segunda sección del tratado cuarto donde incluye un titulus dedicado a la acedia, en el que luego de precisar la definición de este vicio, discute acerca de su condición de pecado. El propósito de esta comunicación es exponer y comentar el concepto de acedia que propone Alejandro, haciendo hincapié en la recepción de algunos conceptos aristotélicos que allí se manifiesta, a través de una aproximación etimológica, una aproximación conceptual y su ubicación en un género determinado. La conclusión permitirá determinar que, para Alejandro como para los Padres del Desierto, la acedia es el desorden de la espiritualidad que impide que el monje o el religioso alcancen la contemplación. En el caso de Evagrio Póntico, el impedimento estará personalizado en un logismos o pensamiento malvado detrás del cual se esconde un demonio; y en el caso de Alejandro, en cambio, será un pecado consistente en una profunda tristeza que lentifica y entumece las fuerzas espirituales.

A Lei nº 13.415/17, que instituiu o Novo Ensino Médio, classifica a Filosofia como estudos e práticas. Tal redação provoca a seguinte indagação: A Filosofia está presente ou não na Formação Geral Básica como disciplina nas matrizes curriculares elaboradas pelas 27 Secretarias Estaduais de Educação? O objetivo geral da pesquisa é analisar o quantitativo de aulas semanais de Filosofia no Novo Ensino Médio nos diferentes estados brasileiros, levando em consideração o ensino nas Redes Públicas Estaduais de Ensino. Assume relevância pelo (...) fato de que há uma necessidade de despertar na comunidade filosófica um movimento de luta pela mudança da redação do texto da Lei nº 13.415/17 de estudos e práticas para disciplina. A pesquisa é bibliográfica, documental e com abordagem qualitativa. Além das fontes bibliográficas atualizadas e do referencial teórico na área de ensino de Filosofia, foram consultadas as leis federais e documentos normativos que se relacionam com a temática. Para o levantamento de dados, foi consultado o _site_ do Observatório Movimento pela Base, que conta com informações sobre a implementação do Novo Ensino Médio e da Base Nacional Comum Curricular, a exemplo das matrizes curriculares. Constatou-se que o terceiro ano do Novo Ensino Médio, que possivelmente será implementado no ano de 2024, é o que possui menor carga horária da disciplina de Filosofia semanalmente. No geral, a carga horária da disciplina de Filosofia foi reduzida em 13 estados, nas redes públicas estaduais de ensino. (shrink)

Augusto Del Noce es uno de los pensadores que más ha incidido en tratar de comprender la sociedad contemporánea en especial a partir del final de la Segunda Guerra Mundial. La originalidad de su análisis radica en especial en la explicación de la génesis de la sociedad presente y en su caracterización de la misma. Este trabajo pretende exponer sus ideas en relación con las de otros filósofos que coinciden en buena medida con él. A partir de tal exposición es (...) posible sacar las consecuencias políticas de su pensamiento social. (shrink)

El principal objetivo de este estudio consiste en dar cuenta de cómo se enmarca la forma de tratamiento nominal marico en el habla de jóvenes universitarios de Caracas, Venezuela, dentro de la Teoría de la cortesía, según la perspectiva ofrecida por los hablantes. Igualmente, se busca documentar qué cambios está presentando en los contextos de uso así como en sus funciones pragmáticas. Los participantes fueron 60 estudiantes universitarios, 30 mujeres y 30 hombres, de 17 a 21 años. Tradicionalmente, la palabra (...) marico se ha usado como agresión verbal vulgar y ha sido, generalmente, considerada un insulto. Luego del análisis cualitativo de los datos, se plantea que esta FTN se halla en una fase de transición de insulto a marcador pragmático anticortés que indica solidaridad dentro de un grupo etario específico y está perdiendo su carácter agraviador. En la actualidad, la juventud caraqueña emplea esta FTN no solo para implicar lazos de amistad, sino para expresar emociones como sorpresa y enojo, crear efectos de intriga, hacer bromas, abrir y cerrar oraciones e, incluso, sustituir otras FTN que nunca han sido consideradas insultos en el español de Venezuela. La metodología empleada fue el cuestionario y el análisis cualitativo de reportes en primera persona. Las variables de edad y sexo son factores determinantes, puesto que parece haber tendencia entre los jóvenes entrevistados a no emplear esta forma nominal con hablantes que están fuera de su grupo etario y las mujeres siguen siendo conservadoras al restringir, más que los hombres, el uso de este vocablo.

Se busca rastrear la imagen que Platón tiene de Heráclito y articularla con la estructura argumentativa del Cratilo, para comprender las necesidades textuales a las que responde la doctrina del flujo perpetuo, es decir, la discusión sobre la corrección (ὀρθότης) del nombre. Gracias a la inclusión del testimonio heraclíteo, resulta posible rastrear la presunta consolidación de la tesis sobre los nombres primarios y los secundarios como el eje de la separación entre dos planos de realidad (uno estable y uno móvil) (...) y de la teoría de las Ideas -es decir, como la base de la epistemología platónica presente en los diálogos de madurez-. The article seeks to trace the image Plato has of Heraclitus and connect it with the argumentative structure of the Cratylus in order to understand the textual needs that give rise to the doctrine of perpetual flux, that is, the discussion regarding the correctness (ὀρθότης) of names. The inclusion of Heraclitus's testimony makes it possible to trace the alleged consolidation of the thesis regarding primary and secondary names as the axis of separation between two levels of reality (one stable, the other, changing) and the theory of Ideas -that is, as the basis of Plato's epistemology as set forth in the late dialogues-.

This review essay engages critically with Heikki Patomäki's The Political Economy of Global Security: War, Future Crises, and Changes in Global Governance. The book is built around the hypothesis that the current ‘era of Neoliberalism’ shares many similarities to the era of the ‘new imperialism’ of the late nineteenth century, ending, catastrophically, in World War I and the Great Depression. Patomäki undertakes this comparison by focusing on the principal long-term historical processes, structures, tendencies and contradictions that may be responsible for (...) the similarities between these two eras. To do so Patomäki constructs an explanatory model of the underlying causal processes and mechanisms involved. The implications are ominous and urgent. The essay uses a close examination of this exemplary case of critical realism in social science to discuss critically its historical explanations, the comparative analysis it makes, and especially the question of agency as theorised in the author's ‘future scenarios’.

True enough, not many of the human lot we know, not least of all thosewe may chance upon in life in an intricate tangle of modern socialformations where individuals get to interface rather unreflectively mostof the time, would be so generous as to bestow a casual interest in philosophy. Two thousand years ago, this kind of antipathy toward philosophy made its point well when a man named Socrates was condemned to death, proof rather of the unchanging isometrics of equivocation in (...) the face of the compelling demands of justice and truth that Socrates exposed to be the skeleton in the cupboard of power, hiding under the façade of indestructibility. This pervasive practice would have by now covered an entire époque of Western intellectualtradition from the death of Socrates to the contemporary, disguised asunwavering love of everything that abounds in beauty and vitality, adetermined search for the fundament that holds everything together under the condition that Man is free and that Life is precious as too rich and valuable for the taking.

Martin Heidegger and Immanuel Kant - two important pillars of contemporary philosophy-were proficient critics of traditional metaphysics in their time. They were known to be critical of a sort of metaphysical striving predisposed to grounding or representing an elusive concept of the universal.. Kant had earlier deconstructed a pre-eminent feature of Western metaphysics, namely, the socalled essence of thing, had it consigned to the noumenon evocative of the paradoxical nature of human knowing: it regulates the boundaries according to which any (...) notion of the infinite, the universal or the absolute can be reflexively thematized, or, thus strategically said, problematized.

Although in Italy there is currently no effective law on physician-assisted suicide or euthanasia, Decision No. 242 issued by the Italian Constitutional Court on September 25, 2019 established that an individual who, under specific circumstances, has facilitated the implementation of an independent and freely-formed resolve to commit suicide by another individual is exempt from criminal liability. Following this ruling, some citizens have submitted requests for assisted suicide to the public health system, generating a situation of great uncertainty in the application (...) processes. As a matter of fact, shared and defined procedures are lacking as Decision 242/2019 merely added some principles on which the legislature will have to base its future intervention. This paper analyses the advisory role that the Decision attributes to territorial ethics committees with the aim of stimulating discussions on their role in oversight mechanisms. The proposed conclusion is that the envisaged role does not appear consistent with the functions of these bodies and is ultimately substantially undefined and unjustified. (shrink)

Los fondos de inversión se han convertido en los últimos años en un mecanismo frecuente que los clubes de fútbol utilizan para financiar el fichaje de jugadores. Aunque muchos autores han destacado sus efectos beneficiosos al permitir que los clubes adquieran jugadores que de otra manera no podrían conseguir, en este trabajo nos centramos en enfatizar dos problemas que pueden plantear. En primer lugar, hemos tratado de mostrar que pueden generar un progresivo alejamiento de los aficionados. En segundo lugar, a (...) través del dilema del prisionero nos hemos propuesto mostrar que pueden contribuir a aumentar a largo plazo la deuda de los clubes y amenazar el fair play financiero.Investment funds have become in recent years a frequent mechanism football clubs use to finance signing of football players. Although many authors have highlighted their beneficial effects by allowing clubs to acquire players who otherwise they would not get, in this paper we focus on two problems. First, we have tried to show that they can generate a progressive distancing from the fans. Secondly, through the prisoner’s dilemma we intend to show that they can contribute to increasing long-term clubs debt and threaten the financial fair play. (shrink)

The question of immigration and its corollary community and minority formation has always been analysed in relation to states. However, the increasing importance of solidarity beyond national borders on the grounds of one or several identities – national, religious, ethnic, regional – removes the claim of recognition of a collective identity from a national level to an international level and, in the European Union, to a supranational level. Such an evolution places territory at the core of the analysis of citizenship (...) and nationhood, for communities as well as states. This article will attempt to show that in this new configuration, negotiations between states and immigrants are brought beyond borders in order for states to maintain the ‘power’ of incorporation and citizenship while expanding their influence beyond their territories and to compete with transnational communities in their engagement in the process of globalization.

The Brentano influence on Husserl’s phenomenology is an established fact. Husserl first major work (1891) did not hide his adherence to the Brentano method, against which, however, he rebelled in his next work, the Logical Investigations (1900/01), and more explicitly in the second edition (1913). Since then, it has been emphasized that phenomenology emerges from, and against, Brentano psychology as a method but, frequently, other important criticisms are overlooked. This paper aims to investigate these criticisms, going beyond the methodologic question. (...) To this end, Brentano’s ideas are exposed, followed by Husserl’s criticism, qualifying them o correcting them when necessary. (shrink)

El objetivo de este trabajo es reflexionar, a partir de algunos textos clave de Joseph Ratzinger, acerca de la relación que el cristianismo siempre ha tenido con la filosofía y con el tipo de racionalidad que se desarrolló en Occidente. El cristianismo nunca se ha asumido como una propuesta religiosa más, sino como "la verdad revelada". Desde sus orígenes ha tenido que convivir con múltiples ofertas religiosas y hoy en día no puede sustraerse a ello en un contexto marcado por (...) el pluralismo, como el de nuestra época. Esta condición le impele actualmente a reivindicar su carácter racional inherente y afrontar los desafíos que cierto irracionalismo de la cultura posmoderna le pone frente a sí. (shrink)

Después de los excesos y de las contradicciones a las que condujeron los diferentes humanismos que caracterizaron a la Modernidad, tanto ilustrada como tardía, el pensamiento contemporáneo ha caído en un pesimismo, hasta cierto punto justificado, respecto a las potencialidades emancipadoras y humanizadoras de la racionalidad autónoma y crítica que caracterizó a esa época. El pesimismo actual reniega del ser humano como valor y como ideal, también con cierta razón, abriendo el camino a una era antihumanista y posthumana. Desde el (...) punto de vista de la tradición cristiana se pretende recuperar el humanismo; no puede decirse que sea un nuevo humanismo pero sí uno originario. Lo que entenderemos aquí por humanismo cristiano es el resultado de la confluencia entre esas dos tradiciones que configuran el rostro de occidente,. Este debe ser un humanismo autocrítico, mesurado y autolimitado, que bajo el concepto de creaturalidad –y la contingencia que de él se deriva– pretende revalorar al hombre en el marco más general de su finitud y de su necesaria conformidad con la ley natural; de esta manera se busca recuperar ambas raíces y pilares que han definido a la cultura occidental.

This essay discusses the aesthetic potential within Bernard Stiegler’s concept of technics, particularly its nascent or preactual form of realism. This realism fosters a sense of spontaneity, crucial to a modal engagement with time, being, and history in the face of contemporary planetary enframing. By critically appraising Stiegler’s framework, the essay proposes an aesthetics of care that aligns with restoring art’s primordial inhumanism. This stands in stark contrast to the inhumanism inherent in technological modernity. Reviving this aesthetics, a global challenge (...) that traverses East and West, might appear anachronistic. It proposes a return to the primordial integration of the human and inhuman, initially enshrined in art as technics (evident as far back as the Upper Paleolithic). Modern technology, however, severs the organological function of art from its foundational relation with humanity. In this dismemberment, a singular, immanent humanism emerges as the defining characteristic of modernity. This human becomes wholly accessible and subservient to technology, thus negating the reciprocal tension that defines their elemental and productive relationship, their original organology or how life at the time was intensively organized by this so-called tension. In conclusion, the essay advocates restoring this lost inhuman essence through a revitalized aesthetic sensibility that embraces an integral ecology as a countermeasure to stagnation and despair engendered by excessive human-centric enframing.

La autora explica el consumo adolescente por su sentido reafirmador en esa etapa, analiza el impacto de ellas en el sistema nervioso, postula que a población tiende a autorregular su consumo, distingue el abuso de la dependencia a las drogas y lo vincula al contexto de la vida adolescente, en particular en los sectores pobres. Finalmente aborda el tema de la rehabilitación y debate el contexto social en sus estrategias ante los jóvenes consumidores.

El objetivo de este trabajo es analizar un aspecto parti-cular de la demonología alejandrina y siríaca a partir del así llamadoδαίμων πλάνος o demonio errante, que Evagrio Pón-tico presenta en su tratado Sobre los pensamientos. Este demonio tiene como misión particular distraer al monje de la finalidad que le es pro-pia y disponerlo al ataque de demo-nios más peligrosos y dañinos. Esta figura es inaugurada por Evagrio y retomada algunos siglos más tarde por autores siríacos que la desarro-llan y aplican (...) de diversos modos en sus obras espirituales. Me detendré, además del texto evagriano, en la obra de uno de sus comentadores más reconocidos: José Hazzaya. (shrink)

Si bien la influencia de Clemente de Alejandría sobre Evagrio Póntico ha sido señalada por autores como Antoine Guillaumont y Paul Géhin, este trabajo se orienta a considerar su presencia en el círculo de los discípulos de Evagrio y, paralelamente, reconsiderar las temáticas en las que, efectivamente, existió tal influencia. Utilizaré como texto de base para el análisis los Chapitres des disciples d’Évagre, un largo texto que reúne una serie de breves capítulos o kephalaia con enseñanzas de Evagrio que fueron (...) recogidas por sus discípulos, en los que puede observarse la influencia clementina. Me detendré particularmente en dos conceptos importantes para ambos autores: la apatheia y la amistad espiritual, lo cual permitirá, a mi entender, relativizar la autoridad de Clemente en Evagrio y los círculos cultos de los Padres del Desierto.

Background Informed consent is one of the key principles of conducting research involving humans. When research participants give consent, they perform an act in which they utter, write or otherwise provide an authorisation to somebody to do something. This paper proposes a new understanding of the informed consent as a compositional act. This conceptualisation departs from a modular conceptualisation of informed consent procedures. Methods This paper is a conceptual analysis that explores what consent is and what it does or does (...) not do. It presents a framework that explores the basic elements of consent and breaks it down into its component parts. It analyses the consent act by first identifying its basic elements, namely: a) data subjects or legal representative that provides the authorisation of consent; b) a specific thing that is being consented to; and c) specific agent(s) to whom the consent is given. Results This paper presents a framework that explores the basic elements of consent and breaks it down into its component parts. It goes beyond only providing choices to potential research participants; it explains the rationale of those choices or consenting acts that are taking place when speaking or writing an authorisation to do something to somebody. Conclusions We argue that by clearly differentiating the goals, the procedures of implementation, and what is being done or undone when one consent, one can better face the challenges of contemporary data-intensive biomedical research, particularly regarding the retention and use of data. Conceptualising consent as a compositional act enhances more efficient communication and accountability and, therefore, could enable more trustworthy acts of consent in biomedical science. (shrink)

A wide array of species throughout the animal kingdom has shown the ability to distinguish between quantities. Aside from being important for optimal foraging decisions, this ability seems to also be of great relevance in group-living animals as it allows them to inform their decisions regarding engagement in between-group conflicts based on the size of competing groups. However, it is often unclear whether these animals rely on numerical information alone to make these decisions or whether they employ other cues that (...) may covary with the differences in quantity. In this study we used a touch screen paradigm to investigate the quantity discrimination abilities of two closely related group-living species, wolves and dogs, using a simultaneous visual presentation paradigm. Both species were able to successfully distinguish between stimuli of different quantities up to 32 items and ratios up to 0.80, and their results were in accordance with Weber's law (which predicts worse performances at higher ratios). However, our controls showed that both wolves and dogs may have used continuous, non-numerical cues, such as size and shape of the stimuli, in conjunction with the numerical information to solve this task. In line with this possibility, dogs' performance greatly exceeded that which they had shown in other numerical competence paradigms. We discuss the implications these results may have on these species' underlying biases and numerical capabilities, as well as how our paradigm may have affected the animals' ability to solve the task.

La relación entre lengua y sexualidad recién ha comenzado a cobrar importancia dentro de los estudios socioculturales. Este trabajo explora las distintas pistas lingüísticas encriptadas en el cuento La búsqueda de Elizabeth, de Marta Pessarrodona, para desenmascarar la velada identidad sexual del personaje central. Un análisis referente al proceso de reconocimiento, búsqueda y aceptación de una identidad sexual no canónica de la protagonista validará los cuatro principios propuestos por Bucholtz y Hall : afloramiento, indexicalidad, relacionalidad y parcialidad.
