Why do humpback whales sing? This paper considers the hypothesis that humpback whales may use song for long range sonar. Given the vocal and social behavior of humpback whales, in several cases it is not apparent how they monitor the movements of distant whales or prey concentrations. Unless distant animals produce sounds, humpback whales are unlikely to be aware of their presence or actions. Some field observations are strongly suggestive of the use of song as sonar. Humpback whales sometimes stop (...) singing and then rapidly approach distant whales in cases where sound production by those whales is not apparent, and singers sometimes alternately sing and swim while attempting to intercept another whale that is swimming evasively. In the evolutionary development of modern cetaceans, perceptual mechanisms have shifted from reliance on visual scanning to the active generation and monitoring of echoes. It is hypothesized that as the size and distance of relevant events increased, humpback whales developed adaptive specializations for long-distance echolocation. Differences between use of songs by humpback whales and use of sonar by other echolocating species are discussed, as are similarities between bat echolocation and singing by humpback whales. Singing humpback whales are known to emit sounds intense enough to generate echoes at long ranges, and to flexibly control the timing and qualities of produced sounds. The major problem for the hypothesis is the lack of recordings of echoes from other whales arriving at singers immediately before they initiate actions related to those whales. An earlier model of echoic processing by singing humpback whales is here revised to incorporate recent discoveries. According to the revised model, both direct echoes from targets and modulations in song-generated reverberation can provide singers with information that can help them make decisions about future actions related to mating, traveling, and foraging. The model identifies acoustic and structural features produced by singing humpback whales that may facilitate a singer’s ability to interpret changes in echoic scenes and suggests that interactive signal coordination by singing whales may help them to avoid mutual interference. Specific, testable predictions of the model are presented. (shrink)

We agree with Rendell and Whitehead that cetaceans acquire knowledge from caretakers and peers, and that a clear understanding of this process can provide insight into the evolution of mammalian cognition. The passive observational methods they advocate, however, are inadequate for determining what cetaceans know. Only by experimentally investigating the cognition of cetaceans can we hope to understand what they learn through social interactions.

The theoretical framework proposed by Dienes & Perner sets the wrong standards for knowledge to be considered explicit. Animals other than humans possess knowledge, too, some of which is probably explicit. We argue that a comparative approach to investigating knowledge is likely to be more fruitful than one based on linguistic constructs and unobservable phenomena.

Singing humpback whales (Megaptera noavaengliae) collectively and progressively change the sounds and patterns they produce within their songs throughout their lives. The dynamic modifications that humpback whales make to their songs are often cited as an impressive example of cultural transmission through vocal learning in a non-human. Some elements of song change challenge this interpretation, however, including: (1) singers often incrementally and progressively morph phrases within and across songs as time passes, with trajectories of change being comparable across multiple time (...) scales; (2) acoustically isolated subpopulations singing similar songs morph the acoustic properties of songs in similar ways; and (3) complex sound patterns, including phrases, themes, and whole songs, recur across years and populations. These properties of song dynamics suggest that singing humpback whales may be modulating song features in response to local conditions and genetic predispositions rather than socially learning novel sound patterns by copying other singers. Experimental and observational tests of key predictions of these alternative hypotheses are critical to identifying how and why singing humpback whales constantly change their songs. (shrink)

Las expectativas de reconocimiento que tienen los migrantes puede entenderse en desde la noción de falso reconocimiento, en que el sujeto se identifica con la posición desfavorable que le impone la sociedad receptora. Las expectativas de los migrantes están mediadas por la percepción de que se contrae una deuda con la sociedad en virtud de que esta le ha entregado un espacio de oportunidades para la realización de un proyecto de vida orientado al bienestar y la seguridad. Lo cual redunda (...) en una concepción del acceso a los derechos restringida y centrada en el acceso al mercado de trabajo y de bienes de consumo.

O artigo apresenta apontamentos sobre “marketing de guerra santa ” , o planejamento estratégico de gerenciamento de mercado religioso aplicado por algumas das igrejas cristãs da contemporaneidade. Vale-se de reflexões a partir de observação participante e de consulta a bibliografia especializada. Apontam-se algumas das formas com as quais essas igrejas se midiatizam e se inserem num contexto de espetacularização e mercadorização próprios da sociedade do tempo presente e imediato. O mercado religioso no qual se inserem as agências que (...) praticam este tipo de marketing passa por contextos de adequação ao capital simbólico e ao arcabouço cultural dos fiéis, sendo possível identificar o investimento ideológico e econômico na fabricação e veiculação de suas estratégias, discursos e mercadorias. O objetivo é o de perceber algumas das maneiras com as quais firmas religiosas (tomando como maior exemplo as igrejas neopentecostais) veiculam as mercadorias que produzem ou se apropriam, e os discursos que reverberam, relacionando-os a uma cultura de massa e a uma sociedade espetacular; fomentando a discussão sobre como tais igrejas e outros segmentos religiosos aplicam o marketing de guerra santa para melhor posicionarem sua marca no mercado e conquistarem mais fiéis. Palavras-chave : Marketing de guerra santa. Neopentecostalismo. Mídia. Mercado. Espetáculo da fé.This article presents some notes on Jesus´ marketing, strategic planning of management of religious market applied by some of contemporary Christian churches. For this purpose, the reflections from participant observation and literature on the subject are validated. Some of the ways these churches mediate themselves and are part of a context of spectacle and commoditization are also pointed out. The religious market has adequate to the symbolic capital and to the cultural framework of the participants of the churches. Because of that it is possible to identify the ideological and economic investment in the manufacturing and delivery of their strategies, discourses and products. This article aims to highlight some of the ways in which neo-Pentecostal churches convey the goods they produce and the speeches that reflect them, relating them to a mass culture and a society of the spectacle. Finally, the article wants to encourage the debate on the ways these churches apply the marketing of Jesus in order to co-opt their members and flatten their units Keywords : Holy War’s marketing.

A transição do trabalhador da Idade Média para a Moderna forçou os meios de produção burgueses a criarem modos de positivar a cultura do trabalho. Para além das ideologias e da própria miséria como impulsionadores da cultura do trabalho, o que pretendemos neste artigo é jogar luz sobre o papel das previdências como instrumentos de subjetivação e normalização, originalmente disciplinares; utilizando então uma leitura foucaultiana do tema. Partiremos do como as técnicas disciplinares ajustaram os corpos trabalhadores para o trabalho e (...) fixaram-nos com o auxílio das caixas previdenciárias, até chegarmos à compreensão atual das reformas e contrarreformas previdenciárias como resultados disto que tem sido reconhecido hoje como uma necropolítica. A atualidade, não mais apenas dos trabalhadores europeus, vista então como algo que em nome de uma biopolítica se converteu nesta ultradefesa da vida. Uma defesa que, no seu limite, justificaria até mesmo a morte de larga parcela da população. Temos então a passagem da biopolítica para a necropolítica. E na mesma ordem, temos a passagem de um sistema previdenciário que não é mais feito para o auxílio ou a fixação do trabalhador, mas para a gestão do uso e do descarte deste mesmo sujeito frente ao mercado de trabalho.

El presente artículo indaga si ¿es el sujeto un ser autónomo en la deliberación política o sonlos pensamientos, las posturas y las formas de la organización política mediadas por las distintas herramientas comunicacionales a las que se ve expuesto quienes lo determinan? Así, analiza larelación que existe entre mass media y política, con la capacidad deliberativa del individuo altomar decisiones en el contexto político, a partir de Chomsky y Han. La metodología es cualitativa con diseño documental, el instrumento son fichas (...) bibliográficas aplicadas a fuentes primarias y secundarias. Se usan bases de datos con el algoritmo: “Neoliberalismo, psicopolítica, big data, medios de comunicación de masas y democracia”. Se analizan 13 libros y 20 artículos.

The relationship between phenomenology and the sciences is of complex nature. In particular, the transcendental phenomenological position seems to promote skeptical reservations about the scientific attitude. Phenomenological anthropology and psychology, however, are an exception. The work of the Spanish philosopher Javier San Martin addresses the relationship of Husserlian phenomenology to these two particular sciences. In this paper, the work of Navarrese will be revisited as an occasion to reflect on the relationship between phenomenology and the sciences. In the first part, (...) San Martin’s philosophical approach is presented and put in relation to its counterpart, namely ratiovitalism, which has dominated phenomenological research in the Spanish-speaking world throughout the last decades. The second part is devoted to the question of whether phenomenological transcendentalism is compatible with anthropological research. It also describes San Martin’s contribution to cultural philosophy. The relationship between phenomenology and psychology is discussed in the third part. San Martin develops a critical account of empiricist psychology which he confronts with his proposal for a ’posttranscendental’ psychology that is based on the critique of psychologism and representationalism. The last section compares San Martin’s idea of anthropological and psychological science with other forms of scientific theory which contribute to phenomenological methodology in empirical research.

Although inclusion in formal value chains extends the prospect of improving the livelihoods of rural small-scale producers, such a step is often contingent on compliance with internationally-promoted food safety standards. Limited research has addressed the challenges this represents for small rural producers who, grounded in culturally-embedded food safety conceptions, face difficulties in complying. We address this gap here through a multiple case study involving four public school feeding programs that source meals from local rural providers in the Bolivian Altiplan. Institutional (...) logics theory is used to describe public food safety regulations and to compare them to food safety conceptions in the local indigenous Aymara rural setting. We identify a value-based conflict that leads to non-compliance of formal food safety rules that jeopardizes the participation of small farmers in the market. These include: partial adoption of formal rules; selective adoption of convenient rules; and ceremonial adoption to avoid compliance. Decoupling strategies allow local actors to largely disregard the formal food safety regulations while accommodating traditional cultural practices and continuing to access the market. However, these practices put the long-term sustainability of the farmers’ participation in potentially favorable opportunities at risk. (shrink)

Adding a transparent truth predicate to a language completely governed by classical logic is not possible. The trouble, as is well-known, comes from paradoxes such as the Liar and Curry. Recently, Cobreros, Egré, Ripley and van Rooij have put forward an approach based on a non-transitive notion of consequence which is suitable to deal with semantic paradoxes while having a transparent truth predicate together with classical logic. Nevertheless, there are some interesting issues concerning the set of metainferences validated by this (...) logic. In this paper, we show that this logic, once it is adequately understood, is weaker than classical logic. Moreover, the logic is in a way similar to the paraconsistent logic LP. (shrink)

This important new volume brings together Habermas' key writing on religion and religious belief. Habermas explores the relations between Christian and Jewish thought, on the one hand, and the Western philosophical tradition on the other. In so doing, he examines a range of important figures, including Benjamin, Heidegger, Johann Baptist Metz and Gershom Scholem. In a new introduction written especially for this volume, Eduardo Mendieta places Habermas' engagement with religion in the context of his work as a whole. Mendieta (...) also discusses Habermas' writings in relation to Jewish Messianism and the Frankfurt School, showing how the essays in Religion and Rationality, one of which is translated into English for the first time, foreground an important, yet often neglected, dimension of critical theory. The volume concludes with an original extended interview, also in English for the first time, in which Habermas develops his current views on religion in modern society. This book will be of great interest to students and scholars in theology, religious studies and philosophy, as well as to all those already familiar with Habermas' work. (shrink)

In this article, we will present a number of technical results concerning Classical Logic, ST and related systems. Our main contribution consists in offering a novel identity criterion for logics in general and, therefore, for Classical Logic. In particular, we will firstly generalize the ST phenomenon, thereby obtaining a recursively defined hierarchy of strict-tolerant systems. Secondly, we will prove that the logics in this hierarchy are progressively more classical, although not entirely classical. We will claim that a logic is to (...) be identified with an infinite sequence of consequence relations holding between increasingly complex relata: formulae, inferences, metainferences, and so on. As a result, the present proposal allows not only to differentiate Classical Logic from ST, but also from other systems sharing with it their valid metainferences. Finally, we show how these results have interesting consequences for some topics in the philosophical logic literature, among them for the debate around Logical Pluralism. The reason being that the discussion concerning this topic is usually carried out employing a rivalry criterion for logics that will need to be modified in light of the present investigation, according to which two logics can be non-identical even if they share the same valid inferences.

Until now, North American and European philosophies have been engaged in debates about the possibility of a postmetaphysical philosophy and the consequences of the linguistic turn for the assessment of modernity; they have done so, however, without departing from the narrow horizons of their respective nationalistic perspectives. In this incisive critique, Dussel demonstrates how most of thse philosophies have either failed to give historically faithful analyses of the genesis of the "myth" of modernity, or have never engaged in a serious (...) questioning of their own Eurocentric presuppositions. He shows how North American and European philosophers have presupposed a no-longer-acceptable philosophy of history that has led them to fall into a "developmental fallacy," the belief that there is a linear sequence that moves from the premodern, underdeveloped, or on the way to industrialization, to the modern, developed, and industrialized.

In this paper, we present a non-trivial and expressively complete paraconsistent naïve theory of truth, as a step in the route towards semantic closure. We achieve this goal by expressing self-reference with a weak procedure, that uses equivalences between expressions of the language, as opposed to a strong procedure, that uses identities. Finally, we make some remarks regarding the sense in which the theory of truth discussed has a property closely related to functional completeness, and we present a sound and (...) complete three-sided sequent calculus for this expressively rich theory.

This book explains how the logic of theory change employs formal models in the investigation of changes in belief states and databases. The topics covered include equivalent characterizations of AGM operations, extended representations of the belief states, change operators not included in the original framework, iterated change, applications of the model, its connections with other formal frameworks, and criticism of the model.

En este trabajo se analiza la relación entre los conceptos de fetichismo y lucha de clases en el particular marxismo de Slavoj Žižek. Žižek comprende el fetichismo marxiano a través del psicoanálisis y en el marco de la concepción de Marx de la religión en dos sentidos: como ideología y como fundamento. Esto le permite mostrar que el fetichismo y en general el hecho religioso, no es únicamente «falsa conciencia» sino que también funciona como el elemento constitutivo e insuperable de (...) lo real, lo que, a su vez permite repensar la lucha de clases.

This work aims to make a critical and propositional exposition about the semantics of concepts in general, from the book Transcendental semantics of Kant (2000), by Loparic. In general terms, the exposition of the theme, by this author, focused on the general classification of the semantics of concepts, their meanings and referents. In turn, the critics was directed to several aspects of its exposition, such as: the precision of the nomenclature used, the introduction of new definitions and the correction of (...) others, the reformulation of the classification of the semantics of the concepts. Finally, the proposition highlighted three main points: (i) the conception of the equivalent epistemological status between logic and mathematics, as symbolic sciences with their own form and content; (ii) the weak and strong concept of sciences in general (formal and empirical) as pure and applied sciences, respectively; (iii) the possible metalinguistic conception of the semantics of concepts.

In this passage, Zavaleta describes the connections between the moment of real subsumption, social totalisation, the production of social-scientific knowledge that takes the resultant totality as its object, including Marxist theory, and finally, the emergence of a broad intersubjectivity with the capacity to become a revolutionary historical actor.

There is a long-standing discussion concerning the nature of moral discourse. Multiple views range from realism—according to which moral discourse is closer to scientific discourse than to fictional discourse—to anti-realism—according to which moral discourse is rather closer to fictional discourse. In this paper, I want to motivate a novel anti-realist account. On this view, there are no moral properties or truths, neither mind-independent nor mind-dependent ones (i.e., anti-realism). However, moral cognition results from the use of higher order cognitive abilities with (...) enough resources to grant moral discourse with all the features of a realist talk (i.e., cognitive quasi-realism). I defend this view based on empirical evidence on human moral development and by showing that the resulting account can meet the demands of robust moral realism. The paper concludes by placing the proposed view within the metaethical landscape by comparing it against other forms of anti-realism, most significantly against expressivism. (shrink)
