El uso prolongado de la voz es un factor de riesgo para el desarrollo de patologías vocales en docentes. Actualmente, estos profesionales se ven obligados a usar mascarilla para dictar sus clases, lo que puede resultar en alteraciones vocales. Durante la virtualización de las clases los docentes debieron adaptar algún espacio doméstico para desempeñar sus funciones frente a un computador, disminuyendo la actividad física y fomentando un estilo de vida sedentario, lo que pudo ocasionar algún trastorno músculo-esquelético. Con este panorama, (...) el propósito del estudio es identificar efectos en la voz por la mascarilla y lesiones músculo-esqueléticas en docentes. (shrink)

We survey the use of club guessing and other PCF constructs in the context of showing that a given partially ordered class of objects does not have a largest, or a universal, element.

If κ is any strongly unfoldable cardinal, then this is preserved in a forcing extension in which κ fails. This result continues the progression of the corresponding results for weakly compact cardinals, due to Woodin, and for indescribable cardinals, due to Hauser.

La noción de interpretación desarrollada en el racionalismo crítico de Karl R. Popper muestra atributos específicos que la distinguen de modo sustancial de la interpretación constitutiva de la experiencia que tanto N. R. Hanson como Th. Kuhn defienden en sus respectivas propuestas. Se muestra que la interpretación del modelo popperia-no queda atrapada en una epistemología de corte empirista que la separa de modo radical de toda hermenéutica filosófica.

Suppose that λ=λ <λ ≥ℵ0, and we are considering a theory T. We give a criterion on T which is sufficient for the consistent existence of λ++ universal models of T of size λ+ for models of T of size ≤λ+, and is meaningful when 2λ +>λ++. In fact, we work more generally with abstract elementary classes. The criterion for the consistent existence of universals applies to various well known theories, such as triangle-free graphs and simple theories. Having in mind (...) possible applications in analysis, we further observe that for such λ, for any fixed μ>λ+ regular with μ=μλ+, it is consistent that 2λ=μ and there is no normed vector space over ℚ of size <μ which is universal for normed vector spaces over ℚ of dimension λ+ under the notion of embedding h which specifies (a,b) such that ||h(x)/||x∈(a,b) for all x.

Suppose that λ is the successor of a singular cardinal μ whose cofinality is an uncountable cardinal κ. We give a sufficient condition that the club filter of λ concentrating on the points of cofinality κ is not λ+-saturated.1 The condition is phrased in terms of a notion that we call weak reflection. We discuss various properties of weak reflection. We introduce a weak version of the ♣-principle, which we call ♣*−, and show that if it holds on a stationary (...) subset S of λ, then no normal filter on S is λ+-saturated. Under the above assumptions, ♣*− is true for any stationary subset S of λ which does not contain points of cofinality κ. For stationary sets S which concentrate on points of cofinality κ, we show that ♣*− holds modulo an ideal obtained through the weak reflection. (shrink)

Any account of Spinoza's understanding of attribute must be able to satisfy his definition criterion; that is, it must coherently accommodate the elements involved in his definition of attribute as “what the intellect perceives of a substance as constituting its essence” (E1d4). But this is not enough. There are several available readings that satisfy this criterion and are mutually incompatible. To know what Spinoza means we must supplement his definition criterion with a criterion aiming at consistency with other principles in (...) his system. With the definition and consistency criteria in the backdrop, the aim of this paper is to offer a critical overview of the current state of the debate on Spinoza's theory of attributes. (shrink)

A wide Aronszajn tree is a tree of size and height $\omega _{1}$ with no uncountable branches. We prove that under $MA$ there is no wide Aronszajn tree which is universal under weak embeddings. This solves an open question of Mekler and Väänänen from 1994. We also prove that under $MA$, every wide Aronszajn tree weakly embeds in an Aronszajn tree, which combined with a result of Todorčević from 2007, gives that under $MA$ every wide Aronszajn tree embeds into a (...) Lipschitz tree or a coherent tree. We also prove that under $MA$ there is no wide Aronszajn tree which weakly embeds all Aronszajn trees, improving the result in the first paragraph as well as a result of Todorčević from 2007 who proved that under $MA$ there are no universal Aronszajn trees.

El ensayo explora los principios básicos y los supuestos teóricos del socialismo raizal propuesto por el sociólogo colombiano Orlando Fals Borda. Este socialismo es presentado como una propuesta enraizada en la Investigación Acción Participativa, haciendo énfasis en su origen en las experiencias históricas revolucionarias de los pueblos originarios y diversos sectores populares de América Latina. Igualmente, se resalta su contenido popular, humanista, democrático y epistémico. El ensayo también explora sus acercamientos y sus diferencias con el pensamiento de Marx.

La humanidad evolucionó durante milenios para desarrollar unas características biológicas, culturales, cognitivas y simbólicas comunes, que han posibilitado la expansión de nuestra especie por toda la Tierra y el desarrollo cultural y tecnológico de nuestra era. En este artículo exploramos someramente las ideas del ser humano, proyecciones simbólicas de lo que hemos aspirado a ser, y nos concentramos en la idea moderna autopoiética o de autotransformación, que en nuestro tiempo está postulando la necesidad y posibilidad de una transmutación radical de (...) nuestra especie mediante las bio y neuro tecnologías, generando lo que se denomina «antropotecnologías». El transhumanismo o movimiento de automutación radical de la especie humana nos conducirá, probablemente, a un objetivo que alterará la historia de la humanidad y que, por tanto, debe ser revisado y evaluado desde una perspectiva filosófica y ética por sus profundas consecuencias.

The poem collections Calamina and Amarillo crepúsculo show spaces and landscapes that acquire materiality in poetic language. Despite their clear differences, both texts configure space from a materiality crossed by modernity and its residues. The relation between landscape and poetry is studied using the concept of geo-poetics coined by Michel Collot in Pour une geographie litterair. The article purposes that the poetic subjects of these poems pose their looks on the landscapes’ memory understood as a ruin, instead of exercising the (...) romantic contemplation of the sublime.

Resumen: Este trabajo presenta un estudio empírico sobre la direccionalidad en la traducción de los adverbios de grado chinos. Se ha adoptado una metodología cuantitativa basada en corpus y se ha realizado un estudio cualitativo para analizar las diferencias entre las traducciones directas e inversas de los adverbios de grado en un corpus paralelo construido para este estudio. El resultado muestra que los traductores hispanos prefieren utilizar el método de equivalencia, mientras que los chinos tienden a usar el método de (...) omisión; asimismo, las traducciones inversas presentan un debilitamiento de grado mucho más relevante que las directas. De acuerdo con los hallazgos, se ha establecido que la subjetividad del traductor y las características de los adverbios de grado chinos, como el límite difuso entre las categorías y la degeneración semántica, son los principales factores de divergencias entre las traducciones directas e inversas. Este trabajo completa los estudios sobre la direccionalidad traductológica y la traducción de los adverbios de grado. Abstract: This paper presents an empirical study of the directionality of the translation of Chinese adverbs of degree. We adopt the corpus-based quantitative methodology and the qualitative method to analyze the differences between direct and inverse translations of adverbs of degree in a self-built parallel corpus. The result shows that the Spanish translators prefer to use the equivalence method, while the Chinese tend to use the omission method. Moreover, the inverse translations present a much more prominent weakening of the degree than the direct ones. We find that the subjectivity of the translator and the characteristics of Chinese adverbs of degree, such as the blurred border between different degrees and semantic degeneracy, are the main factors of the discrepancy between direct and inverse translations. This work complements the studies on translation directionality and the translation of adverbs of degree. (shrink)

This paper investigates a connection between the semantic notion provided by the ordering * among theories in model theory and the syntactic SOPn hierarchy of Shelah. It introduces two properties which are natural extensions of this hierarchy, called SOP2 and SOP1. It is shown here that SOP3 implies SOP2 implies SOP1. In Shelah's article 229) it was shown that SOP3 implies *-maximality and we prove here that *-maximality in a model of GCH implies a property called SOP2″. It has been (...) subsequently shown by Shelah and Usvyatsov that SOP2″ and SOP2 are equivalent, so obtaining an implication between *-maximality and SOP2. It is not known if SOP2 and SOP3 are equivalent. Together with the known results about the connection between the SOPn hierarchy and the existence of universal models in the absence of GCH, the paper provides a step toward the classification of unstable theories without the strict order property.

This paper presents a series of meta-analyses of the validity of general mental ability (GMA) for predicting five occupational criteria, including supervisory ratings of job performance, production records, work sample tests, instructor ratings, and grades. The meta-analyses were conducted with a large database of 467 technical reports of the validity of the General Aptitude Test Battery (GATB) which included 630 independent samples. GMA showed to be a consistent predictor of the five criteria, but the magnitude of the operational validity was (...) not the same across the five criteria. Results also showed that job complexity is a moderator of the GMA validity for the performance criteria. We also found that the GMA validity estimates are slightly smaller than the previous ones obtained by Hunter (1983a; Hunter & Hunter, 1984). Finally, we discuss the implications of these findings for the research and practice of personnel selection. (shrink)

Dentre todas as possibilidades de ação feminista, há a militância em espaço público e a prática em apoio às mulheres, bem como a levada de consciência sobre pautas feministas para as mulheres, tanto no âmbito privado como no público. Esta era a abordagem de Andrea Dworkin, que proferia discursos em marchas e levava suas próprias experiências para o âmbito da escrita, sua prática profissional. A mesma abordagem era utilizada por Suzanne Lacy, artista contemporânea que, através de instalações urbanas, realizava suas (...) ações de militância combinada à arte. Este trabalho visa traçar parâmetros comuns entre estas duas mulheres, focando em suas pautas e na reverberação de seus trabalhos um em relação ao outro, bem como na sociedade.Palavras-chave: Público. Arte Contemporânea. Feminismo. AbstractAmongst all possibilities of feminist action there’s the militant strategy: to take the word of action into the public space, to act in women’s aid, to talk to your target audience and bring your discourse to the people. That was Andrea Dworkin’s strategy, who would bring her speeches into women’s marches and take her experience into her writing, which was her profession. The same strategy was taken by Suzanne Lacy, contemporary artist who focuses on urban installations to mix political and artistic action. This paper correlates these two authors, focusing on their preferred subjects and how their works reverberated together and in society.Keywords: Public. Contemporary Art. Feminism. (shrink)

The Internet of Things (IoT) applied to intelligent transport systems has become a key element for understanding the way traffic flow behaves in cities, which helps in decision-making to improve the management of the transport system by monitoring and analyzing network traffic in real time, all with the aim of daily benefiting users of the city’s road infrastructure. Traffic volume estimation in real time, with high effectiveness, may help mobility management and improve traffic flow. Moreover, machine-learning algorithms have shown effectiveness (...) in various scientific fields and have provided a significant platform for achieving intelligent applications. Therefore, we applied various machine learning algorithms to classify the vehicular traffic status in the traffic network of two cities with more than 2 million inhabitants. It was first necessary to establish, from the attributes provided by the datasets, the object class from the LOS (Level of Services) thresholds proposed by the National Academies of Sciences, Engineering, and Medicine, for the basic segments of highways in an urban area. We then selected the attributes of interest using the Recursive Feature Elimination Method (RFE) to reduce the dimensionality of the data, and applied the DT, RF, ET, KNN, and MLP algorithms to train and classify the level of vehicular congestion, defining various volumes of training and validation data. The results show the high effectiveness of the algorithms, highlighting the MLP algorithm as the one that provides the highest effectiveness on average for the evaluated datasets, with a mean precision of 99.5%.

This article intends to demonstrate how Voltaire expresses his ideas through literature. Zadig has been chosen for this intention. Thus, the text promotes a qualitative analysis, comparing Zadig with other texts written by Voltaire. It also considers the context and the author’s personal experiences. Zadig is an example of Voltaire’s manner of using the written word, especially literature, for the defence of his ideas to transform society, combating the infâme, the intolerance, and the authority as an obstacle to knowledge and (...) progress.

De todos estos asuntos trata este libro, que comienza por el pensar y va abriendo su investigación hacia el ser y (...) el hacer." -- Page 4 of cover. (shrink)

This article presents the stance taken by José Ortega y Gasset in the debate that took place in early-twentieth-century Spain regarding the convenience of reading Don Quixote in schools. To this end, we start by describing, albeit briefly, the state of Ortega y Gasset’s thought in 1920, when he writes Biología y pedagogía, the essay with which we shall concern ourselves. According to Ortega y Gasset, Don Quixote must not be read in the classroom because it does not contribute to (...) the development of the students’ spontaneous life, or natura naturans. In order to foster this development, Ortega y Gasset suggests leaving Don Quixote aside and resort to myths such as Odysseus or Heracles because their exploits would excite the students’ vital pulse. However, we suggest several reasons why the aim stated by Ortega y Gasset —and several other highly valuable educational benefits— could be reached resorting to the reading of selected passages of Don Quixote instead of the feats of Odysseus and Heracles.

RESUMENAl analizar si Ludwig Wittgenstein mantiene una posición fundamentalista en Sobre la certeza, suele discutirse si la citada obra se adapta al modelo de fundamentalismo propuesto por Avrum Stroll. Tras exponer las líneas básicas de dicho modelo, en esta nota se mantiene que Sobre la certeza no se adapta al modelo de Stroll debido al importante papel que Wittgenstein concede al contextualismo. Además, se añade que Wittgenstein no puede ser calificado de fundamentalista porque no reconoce ninguna propiedad que, sin tener (...) en cuenta la diversidad de casos particulares, permita justificar de forma conjunta todas nuestras creencias básicas.PALABRAS CLAVEWITTGENSTEIN, FUNDAMENTALISMO, CONTEXTUALISMO, CERTEZAABSTRACTDid Wittgenstein hold a foundationalist position in On Certainty? When this question is tackled, it is often discussed, whether On Certainty fits in the foundationalist model devised by Avrum Stroll. After expounding the main lines of this model, I hold that On Certainty does not fit in Stroll’s model, because of the important role Wittgenstein attaches to contextualism. Furthermore, I add that Wittgenstein cannot be seen as a foundationalist –or a coherentist–, because he does not admit any feature in virtue of which the whole of our basic beliefs are justified without considering circumstances at all.KEYWORDSWITTGENSTEIN, CERTAINTY, FOUNDATIONALISM, CONTEXTUALISM.

Therefore, supervision together with reasonable and precautionary regulation of their effects and consequences -being these expected or unexpected-, in the form of public debate with ample democratic participation proves to be necessary. Nanoethics is a way of starting a reasonable collective rationality movement which, in view of the all-containing span of nanotechnologies, must be constructed from ethic principles that have a global reach and must as well have a prospective character.KEYWORDSNANOTECHNOLOGY, REGULATION, TECHNOLOGICAL RISK, NANOETHICS.

The paper is concerned with the existence of a universal graph at the successor of a strong limit singular μ of cofinality ℵ0. Starting from the assumption of the existence of a supercompact cardinal, a model is built in which for some such μ there are $\mu^{++}$ graphs on μ+ that taken jointly are universal for the graphs on μ+, while $2^{\mu^+} \gg \mu^{++}$ . The paper also addresses the general problem of obtaining a framework for consistency results at the (...) successor of a singular strong limit starting from the assumption that a supercompact cardinal κ exists. The result on the existence of universal graphs is obtained as a specific application of a more general method. (shrink)
