This article is about reductionism; as a tendency of thought, reductionism tells us that the hole can be explained as the sum of its parts. From this principle, one can deduce that the properties and laws of complex systems can be explained by the laws and properties of simple systems. On the other ..

To analyze the concept about scientific fact was the purpose of this work. This concept is a principal element to scientific hypothesis formulation. The properties and characteristics of this must observance were enumerated. Moreover, the concept studied of this work was compared with another.

The variety O2 of double Ockham algebras consists of the algebras (A ∨, ∧, f,g 0,1) of type (2,2,1,1,0,0) where (A; ∨, ∧,f, 0,1) and (A; ∨, ∧,g 0,1) are Ockham algebras. In [16], M. Sequeira introduced several subvarieties of O2. In this paper we give a construction of free double Ockham algebras on a partially ordered set. We also describe free objects for the subvarieties of O2 considered in [16].

Łukasiewicz implication algebras are {→,1}-subreducts of Wajsberg algebras (MV-algebras). They are the algebraic counterpart of Super-Łukasiewicz Implicational logics investigated in Komori, Nogoya Math J 72:127–133, 1978. The aim of this paper is to study the direct decomposability of free Łukasiewicz implication algebras. We show that freely generated algebras are directly indecomposable. We also study the direct decomposability in free algebras of all its proper subvarieties and show that infinitely freely generated algebras are indecomposable, while finitely free generated algebras can be (...) only decomposed into a direct product of two factors, one of which is the two-element implication algebra.

Łukasiewicz implication algebras are the {→,1}-subreducts of MV- algebras. They are the algebraic counterpart of Super-Łukasiewicz Implicational Logics investigated in Komori (Nogoya Math J 72:127–133, 1978). In this paper we give a description of free Łukasiewicz implication algebras in the context of McNaughton functions. More precisely, we show that the |X|-free Łukasiewicz implication algebra is isomorphic to ${\bigcup_{x\in X} [x_\theta)}$ for a certain congruence θ over the |X|-free MV-algebra. As corollary we describe the free algebras in all subvarieties of Łukasiewicz (...) implication algebras. (shrink)

In October 2019, the so-called ‘social outbreak’ took place in Chile, a major socio-political conflict that led to an unprecedented constitutional change in the country. Under this context, the feminist movement takes on a prominent role, not only because of the massiveness of its demonstrations but also because of its influence on the achievement of gender parity in the constitutional process.The experiences of the protests were captured in the countless graffiti that have propagated in urban spaces since the social outbreak (...) and which, even today, abound in certain areas. The aim of this study is to analyse the conceptual metaphors expressed in graffiti related to the Chilean protest. The methodology includes three instances of analysis: the identification of linguistic metaphors; their semantic-discursive grouping; and the conceptual analysis of the established groups, in which the ‘Basic Scene’ component is considered. As a result, the conceptual metaphor PROTEST IS WAR is proposed, which conceptualises Chileans as warriors fighting against an enemy, represented by the political institutionality, the economic model and the patriarchal system. It is concluded that the established metaphor sets out a cognitive dichotomy that highlights the opposition between the participants in the Chilean social conflict and the demonstrators’ discomfort with the current system, emphasising its commitment and unity with the reasons to protest.

In this paper we prove that the free algebras in a subvariety equation image of the variety equation image of semi-Heyting algebras are directly decomposable if and only if equation image satisfies the Stone identity.

An algebraically expandable (AE) class is a class of algebraic structures axiomatizable by sentences of the form $\forall \exists! \mathop{\boldsymbol {\bigwedge }}\limits p = q$. For a logic L algebraized by a quasivariety $\mathcal {Q}$ we show that the AE-subclasses of $\mathcal {Q}$ correspond to certain natural expansions of L, which we call algebraic expansions. These turn out to be a special case of the expansions by implicit connectives studied by X. Caicedo. We proceed to characterize all the AE-subclasses of (...) abelian $\ell $ -groups and perfect MV-algebras, thus fully describing the algebraic expansions of their associated logics. (shrink)

In this paper we continue the study of the variety \ of monadic Gödel algebras. These algebras are the equivalent algebraic semantics of the S5-modal expansion of Gödel logic, which is equivalent to the one-variable monadic fragment of first-order Gödel logic. We show three families of locally finite subvarieties of \ and give their equational bases. We also introduce a topological duality for monadic Gödel algebras and, as an application of this representation theorem, we characterize congruences and give characterizations of (...) the locally finite subvarieties mentioned above by means of their dual spaces. Finally, we study some further properties of the subvariety generated by monadic Gödel chains: we present a characteristic chain for this variety, we prove that a Glivenko-type theorem holds for these algebras and we characterize free algebras over n generators.

In this paper we study the subdirectly irreducible algebras in the variety of pseudocomplemented De Morgan algebras by means of their De Morgan p‐spaces. We introduce the notion of the body of an algebra and determine when is subdirectly irreducible. As a consequence of this, in the case of pseudocomplemented Kleene algebras, two special subvarieties arise naturally, for which we give explicit identities that characterise them. We also introduce a subvariety of, namely the variety of bundle pseudocomplemented Kleene algebras, fully (...) describe its subvariety lattice and find explicit equational bases for each subvariety. In addition, we study the subvariety of generated by the simple members of, determine the structure of the free algebra over a finite set in this variety and their finite weakly projective algebras.

La oveja (Ovis aries) es el primer animal domesticado para consumo en un hito histórico que marca el inicio de la sedentarización de las comunidades humanas al comienzo del Neolítico. Durante milenios, fueron semejantes al muflón asiático (Ovis orientalis), su ancestro salvaje. Las razas primitivas supervivientes en el norte de Europa son oscuras, mudan el pelo estacionalmente, tienen cuernos en ambos sexos y apenas producen lana. Los ancestros de las modernas surgieron hace unos 3.500 años. Se seleccionaron para producir lana (...) blanca, que crece indefinidamente y se colecta anualmente. Este proceso coincide con la invención de las tijeras de esquilar y con el descubrimiento de tintes como la púrpura. Solo la lana blanca puede teñirse de cualquier color, permitiendo trasladar al tejido las mismas señales que quizá antes nos pintábamos con ocre sobre el cuerpo. La oveja, un herbívoro social muy manejable, sumaba al suministro de alimento el de una fibra abrigada y modificable en su color distintiva de quienes la visten. Un lienzo en blanco donde trasponer las expresiones estéticas antes restringidas al cuerpo, al arte rupestre y al mobiliar. De ahí que diversas mitologías contemplen una relación simbólica especial con ellas. La revolución estética propiciada por las ovejas blancas zozobra en el siglo XX con la aparición de nuevas fibras y el abaratamiento de otras. Hoy, los arquetípicos y blancos rebaños característicos de la iconografía occidental tienden a una coloración mixta al devaluarse la lana. Otras especies domésticas con fibras que solo recientemente se han apreciado comercialmente, como las cabras de angora (Capra hircus) o las llamas (Lama glama), siguen un proceso idéntico al emprendido con las ovejas hace milenios para tornarse blancas. Presentamos las implicaciones estéticas que han estimulado la selección artificial de ovejas con lanas blancas desde un punto de vista transdisciplinar. Siguiendo la corriente bioevolutiva, que entiende nuestra conducta estética y sus manifestaciones como parte de nuestra etología, veremos cómo ese largo proceso estuvo incentivado por nuestro deseo de teñir los tejidos para expresar un fenotipo extendido creando una nueva señal social. Esa nueva señalización, operante en el plano de la selección sexual, se va complicando al desarrollarse nuestras capacidades simbólicas y tecnológicas, siendo sintomática del entorno causal en el que se produce.

Despite the promises made by molecular evolutionists since the early 1960s that phylogenies would be readily reconstructed using molecular data, the construction of molecular phylogenies has both retained many methodological problems of the past and brought up new ones of considerable epistemic relevance. The field is driven not only by changes in knowledge about the processes of molecular evolution, but also by an ever-present methodological anxiety manifested in the constant search for an increased objectivity—or in its converse, the avoidance of (...) subjectivity.This paper offers an exhaustive account of the methodological and conceptual difficulties embedded in each of the steps required to elaborate molecular phytogenies. The authors adopt a historical perspective on the field in order to follow the development of practices that seek to increase the objectivity of their methods and representations. These include the adoption and development of explicit criteria for evaluation of evidence, and of procedures associated with methods of statistical inference, quantification and automation. All these are linked to an increasing use of computers in research since the mid 1960s. We will show that the practices of objectivity described are highly dependent on the problems and tools of molecular phylogenetics. (shrink)

El lector me permitirá quizá que le explique de entrada el propósito y el alcance de este brevísimo ensayo, anticipándole los temas de las tres partes que lo componen. Primero, explico lo que quiero decir con la expresión «sociedad civil». Con este fin, describo un tipo o carácter ideal de sociedad civil, en torno al cual he organizado un esquema conceptual que utilizo desde hace años en un amplio programa de investigación en ciencia social; y esbozo las líneas de demarcación (...) entre mi uso de esa expresión y otros usos que se han hecho y se hacen tic ella. Segundo, reelaboro el proceso por el que comencé a utilizar este concepto a mediados de los años setenta. Se trata de un esbozo de reconstrucción, hipotético y fragmentario, del contexto de descubrimiento de aquel esquema conceptual. Es un flash back que me lleva de los primeros sesenta a mi libro Estado, burocracia y sociedad civil, que escribí en 1976 . Tercero, tomo nota de los cambios en mi posición a lo largo de estos años, y me interrogo sobre algunos de los problemas que me han llevado de la concepción de 1976 a la que expongo en La primacía de la sociedad civil de 1993 , y en mis trabajos ulteriores, donde hay un desplazamiento sistemático del énfasis de mi trabajo desde lo que Hamo «sociedad civil sensu stricto» hacia la «sociedad civil sensu lato». La explicación podría radicar en la necesidad de revisar, ampliar y formalizar el esquema «acomodándolo»: uno, al proceso en curso de mis trabajos de investigación empírica, y a la importancia creciente en esos trabajos de los temas de autoridad pública, esfera pública y política pública; dos, al horizonte histórico del whithcring away del totalitarismo comunista; y tres, a mi interés creciente en los temas de tradición, instituciones y retórica. Aunque los tres factores están interrelacionados, centraré aquí mi atención sobre todo en el primero de ellos, es decir, en los estímulos para la re-elaboración del esquema originario que han procedido de mi experiencia de investigación empírica, con alguna referencia al segundo, dejando el tercero poco más que aludido.

We predict multistakeholder benefits as a measure of organizational performance from the perspective of important organizational stakeholders. Specifically, we identify the relative importance of theoretical antecedents that affect the different dimensions of stakeholder benefits. Offering the first empirical synthesis of multistakeholder benefits to date, we assess the statistical explanatory power of different theories in the literature, focusing on the extent to which their suggested antecedents of organizational performance may lead to improvements in multiple dimensions of stakeholder benefits. Based on 110 (...) empirical studies since 1990 to date concerning any two of four stakeholder groups (investors, customers, employees, and community /environment), we find no evidence for any single theory to have sufficient explanatory power in predicting benefits concerning all four stakeholder groups. Thus, we cannot reduce different mechanisms leading to multistakeholder benefits to a grand model or theory but need to resort to a multi-theoretical synthesis. Taking stock of the meta-analysis, we suggest future studies should fill three gaps: multiple dimensions within a stakeholder benefit, causal complexity, and inequality of stakeholder benefit creation.

ArgumentThis paper analyzes the research strategies of three different cases in the study of human genetics in Mexico – the work of Rubén Lisker in the 1960s, INMEGEN's mapping of Mexican genomic diversity between 2004 and 2009, and the analysis of Native American variation by Andrés Moreno and his colleagues in contemporary research. We make a distinction between an approach that incorporates multiple disciplinary resources into sampling design and interpretation (unpacking), from one that privileges pragmatic considerations over more robust multidisciplinary (...) analysis (flattening). These choices have consequences for social, demographic, and biomedical practices, and also for accounts of genetic variation in human populations. While the former strategyunpacksfine-grained genetic variation – favoring precision and realism, the latter tends toflattenindividual differences and historical depth in lieu of generalization.

Los movimientos sociales (MS) son acciones colectivas reiteradas, de confrontación o desborde de las instituciones, con expresiones más o menos organizadas en torno a una reivindicación. Acciones sostenidas de reclamos y demandas, que no se identifican con las instituciones que los generan. La comunicación desde la perspectiva del sujeto se convierte en vehículo de las demandas. La comunicación popular fortalece la acción colectiva interna, mientras que, por otro lado, los medios masivos desarticulan la imagen de los sujetos enfatizando sus intereses (...) al servicio de empresas, corporaciones y conglomerados. Algunas experiencias en el medio rural uruguayo, nos permiten reflexionar: ¿Es posible que los MS sean espacios educativos y constituyan sujetos pedagógicos? ¿Qué función cumple la comunicación popular al interior y al exterior de los MS? ¿Cómo abordar a los medios masivos que banalizan y distorsionan la lucha de los MS? El estudio de los MS ¿es una tarea académica o militante? (shrink)

Aim: The presence of noise in urban environments is rarely considered a factor that causes damage to the environment. The primary generating source is transportation means, with vehicles being the ones that affect cities the most. Traffic noise has a particular influence on the quality of life of those who are exposed to it and can cause health alterations ranging from annoyance to cardiovascular diseases. This study aims to describe the relationship between the traffic noise level and the perceived annoyance (...) in the inhabitants of a city on the Northern Border of Mexico. The work carried out in a city represents the vulnerability characteristics: economic, social, and migratory of its sizable portion of the inhabitants. Due to that, it is impossible to identify precisely the number of residents as the number of vehicles in circulation.Methods: The streets and avenues with an annual average daily traffic of more than 1,000 vehicles were considered for the measurement of traffic noise. The equipment used was a vehicle gauge with non-invasive speed radar; type I integrating sound level meters, with their respective gauges and tripods. A questionnaire was applied to people living within 250 m of the streets and avenues in which the noise was measured.Results: The noise measurement found a parameter of LAeq estimated for 12 h during the day, exceeding 70 dBA. The data received from the questionnaire were statistically tested by using Pearson's correlation tests. A total number of 2,350 people were participated, of whom 1,378 were women and 972 were men. The age of participants is ranged from 18 to 75 years. The overall perception of traffic noise annoyance identified that 1,131 participants responded “Yes” as they considered the noise annoying. Participants who responded “No” as well as those who responded “Do not know” resulted in a total of 1,219 people.Conclusion: The results show that the population is desensitized to traffic noise and does not perceive it as an annoyance. The flow of vehicles and the type of vehicles are the significant factors for the propagation and increase in the traffic noise levels. Women present a considerable appreciation of traffic noise perception instead of younger people who demonstrate a higher tolerance to high-level exposure. This reflects the lack of information of the population around the noise problem and its effects. (shrink)

This study examines the conflation of terms such as “knowledge” and “understanding” in peer-reviewed literature, and tests the hypothesis that little current research clearly distinguishes between importantly distinct epistemic states. Two sets of data are presented from papers published in the journal Public Understanding of Science. In the first set, the digital text analysis tool, Voyant, is used to analyze all papers published in 2014 for the use of epistemic success terms. In the second set of data, all papers published (...) in Public Understanding of Science from 2010–2015 are systematically analyzed to identify instances in which epistemic states are empirically measured. The results indicate that epistemic success terms are inconsistently defined, and that measurement of understanding, in particular, is rarely achieved in public understanding of science studies. We suggest that more diligent attention to measuring understanding, as opposed to mere knowledge, will increase efficacy of scientific outreach and communication efforts. (shrink)

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

Humans are moral creatures. Among all life on Earth, we alone experience rich moral emotions, follow complex rules governing how we treat one another, and engage in moral dialogue. But how did human morality evolve? And can humans become morally evolved? -/- In A Better Ape, Victor Kumar and Richmond Campbell draw on the latest research in the biological and social sciences to explain the key role that morality has played in human evolution. They explore the moral traits that (...) humans share with chimpanzees; how a more complex moral mind enabled Homo sapiens to arise and out-compete other human species; and the place of morality alongside historic revolutions in technology and social organization. Throughout the book, Kumar and Campbell argue that morality co-evolved with intelligence and complex sociality. Morality prevents societal collapse and enables complex knowledge. -/- After unearthing the ancient origins of human morality, Kumar and Campbell use evolutionary theory to deliver profound insights about how to advance moral progress and resist moral regress, such as reducing animal suffering on industrial farms; capitalizing on the recent revolution in gay rights to foster a nascent revolution in transgender rights; opposing intersectional inequality that impacts women and people of color in lower socioeconomic classes; and addressing major problems of global inequality, especially impending crises of injustice caused by anthropogenic climate change. Understanding how we evolved--and how we continue to evolve--can help us become a better ape. (shrink)

Sally Haslanger is concerned with the debate between social constructionists and error theorists about a given category, such as race or gender. For example, social constructionists about race claim that the term “race” refers to a social kind, whereas error theorists claim that the term “race” is an empty term, that is, nothing belongs to this category. It seems that this debate depends in part on the meaning of the corresponding expression, and this, according to some theorists, depends in turn (...) on our intuitions as competent speakers. But then, what should we say if competent users of the expressions “race” and “gender” understand the terms so that being a natural or biological property is a necessary condition in order to fall under the term? If that were the case, then it would seem that a social constructionist view would be out of the question. Haslanger has argued that a social constructionist view could still be defended in that situation. In order to argue for this, she draws on the classical arguments for semantic externalism, which show that the intuitions of competent speakers concerning the nature of a given category, and the objective type that actually unifies the instances of that category, may come apart. In this paper I will argue that the arguments for semantic externalism concerning natural kinds do not really offer support for Haslanger’s claim that ordinary intuitions concerning social kinds are not relevant.

In this paper, I focus on an influential account of phenomenal concepts, the recognitional account, and defend it from some recent challenges. According to this account, phenomenal concepts are recognitional concepts that we use when we recognize experiences as “another one of those.” Michael Tye has argued that this account is viciously circular because the relevant recognitional abilities involve descriptions of the form “another experience of the same type,” which is also a phenomenal concept. Tye argues that we avoid the (...) circularity worry if we explain the reference-fixing of phenomenal concepts in terms of dispositions to re-identify tokens of the same type without appealing to any further phenomenal concepts. However, he argues, this account is incompatible with the intuitive claim that phenomenal concepts seem to involve rich modes of presentation of their referents. Philip Goff and others have similarly argued that a recognitional account of phenomenal concepts would make phenomenal concepts opaque, that is, unable to reveal anything about their referents, which seems problematic. In this paper, I present a new version of the recognitional account that avoids the circularity worry without entailing that phenomenal concepts are opaque. (shrink)

Pourquoi s'interroger sur la possibilité de l'existence d'une philosophie au Chili? Voici la question traitée ici, en prenant comme axe le travail intellectuel du philosophe chilien Jorge Eduardo Rivera, décédé en janvier 2017, après l'écriture de cet ouvrage. Jorge Eduardo Rivera représente parfaitement le travail philosophique et universitaire. Celui qui se réalise dans le plus grand silence, hors de toute stridence ou de toute mode. Etranger au raffut des bavardages qui nous inonde. Une méditation sobre, loin de toute bouffonnerie. Peut-être (...) est-ce cela qui amena Rivera à décrire simplement et profondément des zones inconnues, éclairées par une parole qui, sans être poétique, nous renvoie à l'être en tant que tel et sous toutes ses formes. Ce livre présente l'exercice philosophique de Jorge Eduardo Rivera sous un horizon de réflexion à la fois propre et inspiré de la tradition européenne. Il expose sa biographie et son histoire intellectuelle, les différents espaces dans lesquels sa pensée s'est formée, depuis son noviciat et son scolasticat chez les Pères Français, jusqu'à ses études philosophiques et théologiques en Allemagne et ses rencontres avec Heidegger, Gadamer, Fink, Welte, Von Herrmann et Xavier Zubiri.

Al final aparece la figura del Führer, sus manos y el destino de la humanidad.

A discussão sobre a existência ou não da Filosofia Africana, associada à negação do direito à Filosofia caracterizou seis décadas: 1940-2000.

O presente artigo pretende mostrar que existiram, também, pensadores individuais, preciamente no antigo Kôngo.

The central challenges for moral fictionalism are twofold: first, to explain how its recommendation that we abandon moral belief and assertion can be reconciled with its rationale of preserving the motivational efficacy of moral thought and discourse; second, to explain what the point is of replacing moral belief and assertion to begin with. This chapter clarifies these challenges and argues that Richard Joyce’s recent “metaphorist” version of fictionalism fares no better with respect to them than his earlier “narrationist” version. Just (...) like its narrationist predecessor, metaphorist fictionalism fails to secure the motivational efficacy of moral thought and talk. The authors also find faults with yet more recent attempts at answering the above challenges for moral fictionalism, leaving the conservationist recommendation a more attractive alternative. This conclusion could be overturned if the conservationist proposal were sufficiently problematic in other respects, but the authors argue that it isn’t. (shrink)
