The notion of monadic three-valued ukasiewicz algebras was introduced by L. Monteiro ([12], [14]) as a generalization of monadic Boolean algebras. A. Monteiro ([9], [10]) and later L. Monteiro and L. Gonzalez Coppola [17] obtained a method for the construction of a three-valued ukasiewicz algebra from a monadic Boolea algebra. In this note we give the construction of a monadic three-valued ukasiewicz algebra from a Boolean algebra B where we have defined two quantification operations and * such that *x=*x (where (...) *x=-*-x). In this case we shall say that and * commutes. If B is finite and is an existential quantifier over B, we shall show how to obtain all the existential quantifiers * which commute with .Taking into account R. Mayet [3] we also construct a monadic three-valued ukasiewicz algebra from a monadic Boolean algebra B and a monadic ideal I of B. (shrink)
Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)
Although logical consistency is desirable in scientific research, standard statistical hypothesis tests are typically logically inconsistent. To address this issue, previous work introduced agnostic hypothesis tests and proved that they can be logically consistent while retaining statistical optimality properties. This article characterizes the credal modalities in agnostic hypothesis tests and uses the hexagon of oppositions to explain the logical relations between these modalities. Geometric solids that are composed of hexagons of oppositions illustrate the conditions for these modalities to be logically (...) consistent. Prisms composed of hexagons of oppositions show how the credal modalities obtained from two agnostic tests vary according to their threshold values. Nested hexagons of oppositions summarize logical relations between the credal modalities in these tests and prove new relations. (shrink)
In this article, we discuss some issues concerning magical thinking—forms of thought and association mechanisms characteristic of early stages of mental development. We also examine good reasons for having an ambivalent attitude concerning the later permanence in life of these archaic forms of association, and the coexistence of such intuitive but informal thinking with logical and rigorous reasoning. At the one hand, magical thinking seems to serve the creative mind, working as a natural vehicle for new ideas and innovative insights, (...) and giving form to heuristic arguments. At the other hand, it is inherently difficult to control, lacking effective mechanisms needed for rigorous manipulation. Our discussion is illustrated with many examples from the Hebrew Bible, and some final examples from modern science. (shrink)
This paper explores the ethical dilemma of conflicting loyalties found in whistleblowing. Central to this dilemma is the internal/external disclosure dichotomy; disclosure of organisational wrongdoing to an external recipient is seen as disloyal, whilst disclosure to an internal recipient is seen as loyal. Understanding how the organisation and society have dealt with these problems over the last 30 years is undertaken through an analysis of Vandekerckhove’s project, which seeks to place the normative legitimisations of whistleblowing legislation and organisational whistleblowing policies (...) within a globalisation semantic able to contain this conflict between society and the organisation. This project fails, it is argued, because of Vandekerckhove’s particular understanding of the organisation as an autopoietic system, i.e. an operationally closed system. A case is made to understand organisations as complex systems, i.e. operationally open systems. Critical Complexity theory sees the identities of systems and components as coterminous. In the context of the organisation, this means that the identities of the corporation and its corporate members arise and die together. The whistleblower’s disclosure reconfigures the organisation by forcing the organisation to open up and make its boundaries flexible, making the designation ‘internal’ or ‘external’ to the organisation, and, therefore, who qualifies as a recipient of a disclosure of wrongdoing, flexible. The organisation is restrained from retailing against the whistleblower, because its identities are coterminous. Furthermore, as the disclosure cannot be categorically defined as either internal or external, the question of whether an external disclosure can qualify as an act of organisational loyalty becomes moot.

The intersection of ELSI and science forms a complicated nexus yet their integration is an important goal both for society and for the successful advancement of science. In what follows, I present a heuristic that makes boundary identification and crossing an important tool in the discovery of potential areas of ethical, legal, and social concern in science. A dynamic and iterative application of the heuristic can lead towards a fuller integration and appreciation of the concerns of ELSI and of science (...) from both sides of the divide. (shrink)
Abstract This essay seeks to realize the following question: what is the correspondence between the sign and the thing that names? In reality, what is significant is closely linked with the being, however in this case the sense will be a particular manifestation of an own subjectivity; therefore the determinant relation is limited to the capacity of representation, where the meaning is connected with the socio-cultural sense. In this regard, this work seek realize this problem from the analytical approach of (...) Ludwig Wittgenstein, who is based on the method of philosophical investigation through formal logic. In this first period of development, his speculative work, which in principle leads to the search for logical foundations for mathematics, practised it in direction to the study of the nature of the representation. Subsequently, and as necessary this test delimitation, will expose the confrontation —more not necessarily contradiction— of their approaches in the light of the own Wittgenstein who, in a second reflective period poured into his later work, is obliged to discuss the foundational in his speculative work logical-philosophical topics from a pragmatic point of view.

This paper has the following structure: in the first section, I report on the historical and philosophical roots of the problems of knowledge and justification; in the second, I lay out the distinction between truth and epistemic justification; the third section is devoted to the problem of circularity, a problem often attributed to coherentism; in the fourth section, I introduce an unorthodox notion of justification, systemic justification; in the fifth, I present and criticize another unorthodox notion of justification, non-linear inferential (...) justification; in the sixth, I discuss a few other distinctions and focus on the propositional and doxastic forms of justification; the examination of those forms is subsequently developed in the seventh section; I conclude with a reflection on the nature and limits of my proposal.

The present article is framed within the biosemiotic glossary project as a way to address common terminology within biosemiotic research. The glossary integrates the view of the members of the biosemiotic community through a standard survey and a literature review. The concept of ‘semiotic threshold’ was first introduced by Umberto Eco, defining it as a boundary between semiotic and non-semiotic areas. We review here the concept of ‘semiotic threshold’, first describing its denotation within semiotics via an examination on the history (...) of the concept, its synonyms, antonyms, etymology, usage in other languages and context in which it is used. Then we present a general overview of the survey among researchers, analyzing the difference in responses for the concept of ‘lower semiotic threshold’ and related concepts. From the answers we also review the difference between the general usage of ‘semiotic threshold’ versus its specific use within biosemiotics, and attempt to make a general synthesis of the concept taking into account what we have learned from the survey and the literature review.

The Full Bayesian Significance Test, FBST, is extensively reviewed. Its test statistic, a genuine Bayesian measure of evidence, is discussed in detail. Its behavior in some problems of statistical inference like testing for independence in contingency tables is discussed.
According to the orthodox or humanist conception of human rights, individuals have a moral duty to promote the universal realization of human rights. However, advocates of this account express the implications of this duty in extremely vague terms. What does it mean when we say that we must promote human rights satisfaction? Does it mean that we must devote a considerable amount of our time and resources to this task? Does it mean, instead, that we must make occasional donations to (...) charities working to advance human rights realization? In this essay, I argue that this duty can only be constructed as imperfect. This means that it confers agent-relative discretion on us to decide when, how, and to what extent to advance the human rights of others. It also means that it is neither correlative with rights nor enforceable. As I will explain, the main reason for this is that any attempt to construct it as a perfect duty would infringe the dignity of the potential duty bearers and thereby undermine the very values that human rights practice aspires to serve. Finally, I will conclude by providing some guidelines for those who wish to comply with their imperfect duties to improve the situation of those whose human rights are in peril. (shrink)
Biological boundaries are important because of what they reveal about the evolution of a lineage, the relationship between organisms of different lineages, the structure and function of particular subsystems of the organism, the interconnection between an organism and its environment, and a myriad of other important issues related to individuality, development, and evolution. Since there is no single unifying theory for all biological sciences, there are various possible theoretical characterizations of what counts as a biological boundary. Theoretical specificity is crucial (...) for the full characterization of a boundary; to this end, it is useful to begin with general properties and then to compare these to those properties specific to a particular biological boundary. This dual heuristic approach—top-down and bottom-up—can then be repeated to increase the robustness of the boundary characterization. In what follows, I explore both the general structural and functional aspects of biological boundaries and those specific to a biological subsystem, which itself is critical to boundary formation, maintenance, and evolution—the vertebrate immune system. It is a remarkable and sobering regularity of nature that organisms remain whole because their parts are constantly being built up and broken down, and this is no less true of their boundaries. The vertebrate immune system is at the center of this process of biological boundary maintenance and breakdown. (shrink)

Studying the origin of semiosis is a task obscured by terminological and metaphysical issues which create an ambiguous set of definitions for biosemiotics when referring to the concept of emergence. The question is, how emergent can semiosis be? And what are the conditions for semiosis to be an emergent of a certain type? This paper will attempt to briefly deal with the general terminology of emergence from a philosophical point of view and will discuss the characterization of semiosis as an (...) emergent phenomenon based on the distinctions made by Bedau, Kim and Chalmers. Accordingly, we will consider the possibility of strong and weak emergence in an attempt to bring some clarity to what it means for something in biosemiotics to be an emergent and how the philosophical concepts play out when applied to biosemiotic research. In inquiring into the metaphysical status of semiosis, we change our semiotic theories to correspond to the assumptions contained in the elementary objects of our theories. This being the case, the way semiosis–the constitutive element that it is for semiotics–is taken to be with regards to its possible ontology, will conduct to different research objects for the long-term investigation of its origins and necessary conditions.

Drawing from extensions of existing ideas in the logic of ground, a novel account of the grounds of necessity is presented, the core of which states that necessary truths are necessary because they stand in specific grounding connections.
La visión imperante en el derecho internacional actual concibe los derechos humanos como normas relativas al trato que los Estados brindan a su propia población. Esta posición, que se conoce como la “perspectiva estatista” sobre los derechos humanos, es actualmente resistida por varios autores. En este artículo intentaré defender la perspectiva estatista contra una serie de críticas recientemente formuladas por Cristina Lafont en Isegoría y en otras importantes revistas especializadas. En particular, trataré de probar que, contrariamente a lo que Lafont (...) argumenta, esta perspectiva captura adecuadamente la razón de ser de la práctica contemporánea de los derechos humanos y dispone de recursos para resguardar los intereses de los seres humanos de las nuevas amenazas surgidas en un mundo globalizado.

En este artículo discuto dos tesis que Thomas Pogge deriva de su concepción institucional de los derechos humanos: la tesis de la culpa y la tesis de la violación global. La tesis de la culpa asevera que los ciudadanos que contribuyen a sostener un régimen institucional que viola derechos humanos sin realizar compensaciones en beneficio de las víctimas, se convierten ellos mismos en violadores de derechos humanos. Por su parte, la tesis de la violación global asevera que al imponer regulaciones (...) injustas que tienden a generar pobreza extrema, el régimen internacional actual viola los derechos humanos de los pobres del mundo. Mi intención será probar que ambas tesis son insostenibles ya que se basan en presupuestos errados en materia de responsabilidad. Esto no nos conducirá, sin embargo, a abandonar la concepción institucional de los derechos humanos. Por el contrario, una vez depurada de sus problemas, se trata de una concepción que puede ayudarnos a pensar adecuadamente sobre la responsabilidad por los derechos humanos en un mundo globalizado. In this paper, I discuss two theses that Thomas Pogge derives from his ins-titutional conception of human rights: the thesis of guilt and the thesis of global violation. The thesis of guilt states that citizens who contribute to support an institutional regime that violates human rights without awarding the victims any compensation become themselves human rights violators. The thesis of global violation, on the other hand, states that, by imposing unfair regulations that tend to generate extreme poverty, the current international regime violates the human rights of the world's poor. My intention is to prove that both theses are untenable because both of them are based on wrong assumptions concerning responsibility. This will not lead us, however, to leave the institutional conception of human rights. On the contrary, once debugged of its problems, it can be considered a conception that can help us to think properly about responsibility for human rights in a globalized world. (shrink)
El autor hace una lectura de la literatura de Cortázar desde la pregunta sobre la proximidad, y señala que la dificultad en delimitar con precisión el lugar de la subjetividad le viene a Cortázar de la desarticulación categorial provista por la herencia cartesiana y del contacto esporádico con el último Heidegger. Afirma que la literatura de Cortázar continúa el derrotero abierto por la modernidad tardía en tanto que los cuestionamientos alcanzan inexorablemente al sujeto.

In this paper, the relationship between the e-value of a complex hypothesis, H, and those of its constituent elementary hypotheses, Hj, j = 1… k, is analyzed, in the independent setup. The e-value of a hypothesis H, ev, is a Bayesian epistemic, credibility or truth value defined under the Full Bayesian Significance Testing mathematical apparatus. The questions addressed concern the important issue of how the truth value of H, and the truth function of the corresponding FBST structure M, relate to (...) the truth values of its elementary constituents, Hj, and to the truth functions of their corresponding FBST structures Mj, respectively.

La identidad, la denominación de un subcontinente y la búsqueda de una racionalidad propia, son los puntos que el autor del artículo retoma como sustanciales de la crítica a la filosofía latinoamericana. Los revisa de modo crítico y encuentra que desde una perspectiva histórica, una política y una económica los tres sustantivos pueden abordarse y validarse desde otras consideraciones filosóficas que no privilegia el método genealógico con el cual se habían tratado las categorías.
This article discusses the mathematizing of the chemical periodic system as a grid, which leads to a quadratic function or “binódica function” formed by pairs of periods or binodos. We describe the periodic law as an increasing function of the principal quantum number. It works subject to the dialectical laws that generate; first: gradual quantitative changes:, with “duplication” of periods:. Second: radical quantitative changes:, with the emergence of new quantum transitions, growth and a change in the format of the binodos. (...) We use analytical and graphic methods to mathematize Mendeleev’s law, making the size of the binodos and the continuous series depend on the number of the binode, which is the same quantum number. Likewise, we show a graphic representation, in 2D, of a continuous and self-similar spiral function of the elements, in a geometric growth pattern. (shrink)
