In this article, a mixed integer linear program model is proposed for the production, lot sizing, and scheduling of automotive plastic components to minimize the setup, inventory, stockout, and backorder costs, by taking into account injection molds as the main index to schedule on parallel flexible injection machines. The proposed MILP considers the minimum and maximum inventory capacities and penalizes stockout. A relevant characteristic of the modeled problem is the dependence between mold setups to produce plastic components. The lot sizing (...) and scheduling problem solution results in the assignment of molds to machines during a specific time period and in the calculation of the number of components to be produced, which is often called lot size, following a sequence-dependent setup time. Depending on the machine on which the mold is setup, the number of units to be produced will be distinct because machines differ from one another. The stock coverage, defined in demand days, is also included in the MILP to avoid backorders, which is highly penalized in the automotive supply chain. Added to this, the proposed model is extended by considering setup common operators to respond to and fulfill the constraints that appear in automotive plastic enterprises. In this regard, the MILP presented solves a lot-sizing and scheduling problem, emerged in a second-tier supplier of a real automotive supply chain. Finally, this article validates the MILP by performing experiments with different sized instances, including small, medium, and large. The large-sized dataset is characterized by replicating the amount of data used in the real enterprise, which is the object of this study. The goodness of the model is evaluated with the computational time and the deviation of the obtained results as regards to the optimal solution. (shrink)

Se problematizan los efectos de las regulaciones escolares sobre los sentidos que les estudiantes del nivel secundario técnico enuncian respecto a la juventud, la formación y su relación con las expectativas de inserción laboral. Trabajamos con un diseño múltiple de investigación a través de datos de encuestas implementadas durante 2018 y entrevistas en profundidad realizadas en 2019 a jóvenes que asisten a un secundario técnico de orientación industrial en Caleta Olivia (Santa Cruz). Nuestros análisis se inscriben en los debates sobre (...) los procesos de escolarización en tiempos en que la regulación escolar se caracteriza por la auto-responsabilización de les sujetes respecto de su propio devenir (Grinberg, 2008). Entre los resultados destacamos que les estudiantes consideran que la regulación del tiempo escolar condiciona la realización de prácticas que asocian a lo juvenil. Para elles ser estudiante de escuela técnica implica un sacrificio que encuentra sus razones en el valor del título para su futura inserción laboral, manifestando cierta persistencia de la promesa de la formación que caracterizó históricamente a dicha modalidad. Por último, consideramos que los sentidos producidos por les estudiantes dan cuenta de la articulación entre formas de regulación con características disciplinarias (Foucault, 2021a) y aquellas propias de las sociedades del rendimiento (Han, 2012).

Fear to contamination is an easy-to-provoke, intense, hard-to-control, and extraordinarily persistent fear. A worsening of preexisting psychiatric disorders was observed during the COVID-19 outbreak, and several studies suggest that those with obsessive–compulsive disorder may be more affected than any other group of people. In the face of worsening OCD symptoms, there is a need for mental health professionals to provide the support needed not only to treat patients who still report symptoms, but also to improve relapse prevention. In this line, (...) it is recommended to improve alternative strategies such as online consultations and digital psychiatry. The aim of this study is to develop augmented reality stimuli that are clinically relevant for patients with cleaning OCD and assess their efficiency to obtain emotionally significant responses. Four AR stimuli were developed: a plastic bag full of garbage, a piece of bread with mold, a dirty sports shoe, and a piece of rotten meat. All stimuli were shown to a clinical group and a control group. Relevant results were the design of the AR stimuli. These stimuli were validated with the statistical difference in perceived anxiety in the meat stimuli between the clinical and control groups. Nevertheless, when looking at effect sizes, all stimuli present effect sizes from small to large, with both shoe and bread between small and medium effect sizes. These results are a valuable support for the clinical use of these AR stimuli in the treatment of cleaning OCD. (shrink)

Olympic combat sports are unconventional physical activity strategies to train middle-aged and older people with and without health problems. This systematic review aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports interventions on health-related quality of life in adults aged 45 and older. The search was carried out in five generic databases until July 2021 and the protocol was registered in PROSPERO. The PRISMA guidelines were followed and the Downs and Black (...) checklist was used to assessed the methodological quality of the studies. After reviewing 1,151 records, only seven studies met the inclusion criteria, adding 212 participants with a mean age of 63.7 years. Six studies provided data to calculate the effect size in the Olympic combat sports groups. Three studies reported beneficial changes with a small ES for the total score of the health-related quality of life. Two studies reported a beneficial change with a small ES and strong ES for physical health. One study reported improvements with a small ES for emotional and functional well-being. In conclusion, interventions based on Olympic combat sports produce beneficial effects with a small and moderate ES on health-related quality of life in male and female aged 45 and older who are healthy participants, participants with Parkinson's disease, and participants with breast cancer.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/, PROSPERO: CRD42021244161.

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)

In this article, we propose some fundamental requirements for the appearance of adaptivity. We argue that a basic metabolic organization, taken in its minimal sense, may provide the conceptual framework for naturalizing the origin of teleology and normative functionality as it appears in living systems. However, adaptivity also requires the emergence of a regulatory subsystem, which implies a certain form of dynamic decoupling within a globally integrated, autonomous system. Thus, we analyze several forms of minimal adaptivity, including the special case (...) of motility. We go on to explain how an open-ended complexity growth of motility-based adaptive agency, namely, behavior, requires the appearance of the nervous system. Finally, we discuss some implications of these ideas for embodied robotics. (shrink)

In some recent articles, Cobreros, Egré, Ripley, & van Rooij have defended the idea that abandoning transitivity may lead to a solution to the trouble caused by semantic paradoxes. For that purpose, they develop the Strict-Tolerant approach, which leads them to entertain a nontransitive theory of truth, where the structural rule of Cut is not generally valid. However, that Cut fails in general in the target theory of truth does not mean that there are not certain safe instances of Cut (...) involving semantic notions. In this article we intend to meet the challenge of answering how to regain all the safe instances of Cut, in the language of the theory, making essential use of a unary recovery operator. To fulfill this goal, we will work within the so-called Goodship Project, which suggests that in order to have nontrivial naïve theories it is sufficient to formulate the corresponding self-referential sentences with suitable biconditionals. Nevertheless, a secondary aim of this article is to propose a novel way to carry this project out, showing that the biconditionals in question can be totally classical. In the context of this article, these biconditionals will be essentially used in expressing the self-referential sentences and, thus, as a collateral result of our work we will prove that none of the recoveries expected of the target theory can be nontrivially achieved if self-reference is expressed through identities.

When discussing Logical Pluralism several critics argue that such an open-minded position is untenable. The key to this conclusion is that, given a number of widely accepted assumptions, the pluralist view collapses into Logical Monism. In this paper we show that the arguments usually employed to arrive at this conclusion do not work. The main reason for this is the existence of certain substructural logics which have the same set of valid inferences as Classical Logic—although they are, in a clear (...) sense, non-identical to it. We argue that this phenomenon can be generalized, given the existence of logics which coincide with Classical Logic regarding a number of metainferential levels—although they are, again, clearly different systems. We claim this highlights the need to arrive at a more refined version of the Collapse Argument, which we discuss at the end of the paper. (shrink)

Dynamicism has provided cognitive science with important tools to understand some aspects of “how cognitive agents work” but the issue of “what makes something cognitive” has not been sufficiently addressed yet, and, we argue, the former will never be complete without the later. Behavioristic characterizations of cognitive properties are criticized in favor of an organizational approach focused on the internal dynamic relationships that constitute cognitive systems. A definition of cognition as adaptive-autonomy in the embodied and situated neurodynamic domain is provided: (...) the compensatory regulation of a web of stability dependencies between sensorimotor structures, is created and preserved during a historical/developmental process. We highlight the functional role of emotional embodiment: internal bioregulatory processes coupled to the formation and adaptive regulation of neurodynamic autonomy. Finally, we discuss a “minimally cognitive behavior program” in evolutionary simulation modelling suggesting that much is to be learned from a complementary “minimally cognitive organization program”.

In different papers, Carnielli, W. & Rodrigues, A., Carnielli, W. Coniglio, M. & Rodrigues, A. and Rodrigues & Carnielli, present two logics motivated by the idea of capturing contradictions as conflicting evidence. The first logic is called BLE and the second—that is a conservative extension of BLE—is named LETJ. Roughly, BLE and LETJ are two non-classical logics in which the Laws of Explosion and Excluded Middle are not admissible. LETJ is built on top of BLE. Moreover, LETJ is a Logic (...) of Formal Inconsistency. This means that there is an operator that, roughly speaking, identifies a formula as having classical behavior. Both systems are motivated by the idea that there are different conditions for accepting or rejecting a sentence of our natural language. So, there are some special introduction and elimination rules in the theory that are capturing different conditions of use. Rodrigues & Carnielli’s paper has an interesting and challenging idea. According to them, BLE and LETJ are incompatible with dialetheia. It seems to show that these paraconsistent logics cannot be interpreted using truth-conditions that allow true contradictions. In short, BLE and LETJ talk about conflicting evidence avoiding to talk about gluts. I am going to argue against this point of view. Basically, I will firstly offer a new interpretation of BLE and LETJ that is compatible with dialetheia. The background of my position is to reject the one canonical interpretation thesis: the idea according to which a logical system has one standard interpretation. Then, I will secondly show that there is no logical basis to fix that Rodrigues & Carnielli’s interpretation is the canonical way to establish the content of logical notions of BLE and LETJ. Furthermore, the system LETJ captures inside classical logic. Then, I am also going to use this technical result to offer some further doubts about the one canonical interpretation thesis. (shrink)

Numerous researchers have examined the antecedents of trust between managers and subordinates. Recent studies conclude that their influence varies depending on whether what is being examined is a manager's trust in a subordinate or a subordinate's trust in a manager. However, the reasons given to justify this phenomenon present limitations. This article offers a new theoretical approach that relates the influence of each antecedent to Aristotelian forms of reasoning, ethical, and instrumental. The proposed approach shows that the influence of each (...) antecedent depends on which rationality prevails in the person who trusts. The contribution of this article is to better explain the phenomenon of interpersonal trust formation and its logic, while offering at the same time several practical implications for managers interested in developing an organizational culture based on trust. The article begins with a literature review of more relevant empirical studies analyzing superior–subordinate trust formation and presents some theoretical limitations of the arguments described in these works. Then, it offers a new theorerical approach based on Aristotelian thought to explain the influence of the antecedents of trust in management–subordinate relationships. The theoretical contribution is then confirmed in an empirical study of 163 mid-level managers in Spain. (shrink)

The concept of _substructural logic_ was originally introduced in relation to limitations of Gentzen’s structural rules of Contraction, Weakening and Exchange. Recent years have witnessed the development of substructural logics also challenging the Tarskian properties of Reflexivity and Transitivity of logical consequence. In this introduction we explain this recent development and two aspects in which it leads to a reassessment of the bounds of classical logic. On the one hand, standard ways of defining the notion of logical consequence in classical (...) logic naturally induce substructural logics when admitting more than two truth values; on the other hand, these substructural logics give rise to hierarchies of _metainferences_ that can be used to approximate classical logic at different levels.

This article develops an axiomatic theory of induction that speaks to the recent debate on Bayesian orgulity. It shows the exact principles associated with the belief that data can corroborate universal laws. We identify two types of disbelief about induction: skepticism that the existence of universal laws of nature can be determined empirically, and skepticism that the true law of nature, if it exists, can be successfully identified. We formalize and characterize these two dispositions toward induction by introducing novel axioms (...) for subjective probabilities. We also relate these dispositions to the axiom of σ-additivity.

In this theoretical paper, I analyze business groups’ corporate social responsibility. Building on economic thinking, I propose that the level and diversity of CSR investments of business groups evolve with the development of the country, as a result of the interaction of two drivers: the level of infrastructure deficiencies and the cost of negative externalities. I argue that in underdeveloped countries, business groups have high levels and low diversity of CSR investments, focusing on the social arena to compensate for infrastructure (...) deficiencies. As countries implement pro-market reforms and become emerging economies, the level of CSR investments diminishes as business groups can rely on external providers and the government for supporting infrastructure, but CSR diversity increases to address the growing costs of negative externalities in the environmental and economic arenas. As countries further develop to become advanced economies, business groups’ level and diversity of CSR investments increase to prevent the high costs of negative externalities in the social, environmental, and economic arenas proactively.

It is widely accepted that a theory of truth for arithmetic should be consistent, but -consistency is a highly desirable feature for such theories. The point has already been made for first-order languages, though the evidence is not entirely conclusive. We show that in the second-order case the consequence of adopting -inconsistent theories of truth are considered: the revision theory of nearly stable truth T # and the classical theory of symmetric truth FS. Briefly, we present some conceptual problems with (...) ω-inconsistent theories, and demonstrate some technical results that support our criticisms of such theories. (shrink)

Both the irreducible complexity of biological phenomena and the aim of a universalized biology (life-as-it-could-be) have lead to a deep methodological shift in the study of life; represented by the appearance of ALife, with its claim that computational modelling is the main tool for studying the general principles of biological phenomenology. However this methodological shift implies important questions concerning the aesthetic, engineering and specially the epistemological status of computational models in scientific research: halfway between the well established categories of theory (...) and experiment. ALife models become powerful epistemic artefacts allowing the simulation of emergent phenomena, the interaction between different levels of organization and the integration of different causal factors in the very same manipulable object. The use of computational models in ALife can be classified in four main categories depending on their position between theoretical and empirical practices: generic, conceptual, functional and mechanistic. For each of these categories we analyse their epistemic value and select paradigmatic examples that illustrate how ALife models can be fruitfully inserted in the study of life. (shrink)

Transhumanist thought on overpopulation usually invokes the welfare of present human beings and the control over future generation, thus minimizing the need and meaning of new births. Here we devise a framework for a more thorough screening of the relevant literature, to have a better appreciation of the issue of natality. We follow the lead of Hannah Arendt and Brent Waters in this respect. With three overlapping categories of words, headed by “natality,” “birth,” and “intergenerations,” a large sample of books (...) on transhumanism is scrutinized, showing the lack of sustained reflection on the issue. After this preliminary scrutiny, a possible defense of natality in face of modern and transhumanist thought is marshaled, evoking a number of desirable human traits. One specific issue, the impact of modern values on natality, is further explored, reiterating that concerns about overpopulation and enhanced humans should keep in sight the natural cycle of birth and death.

Resumo: Neste artigo, propõe-se uma confrontação entre a teoria dos signos de Gotthold E. Lessing, tal como exposta em Laocoonte ou sobre as fronteiras da pintura e da poesia, e os dois ensaios de Theodor W. Adorno sobre as relações entre música e pintura. Pretende-se, com isso, demonstrar a presença decisiva de elementos da estética clássica alemã no pensamento adorniano do pós-guerra; em particular, observa-se o modo pelo qual a teoria racionalista de Lessing atua na abordagem dialética adorniana a respeito (...) da irredutibilidade formal dos meios artísticos e das possibilidades de sua convergência. À luz de tal confrontação, discutem-se, em um segundo momento do artigo, os temas da conferência de Adorno de 1966, A arte e as artes, que, em certa medida, consubstancia a discussão dos ensaios anteriores sobre música e pintura. Assinala-se, nesse contexto, a continuidade da posição teórica de Adorno e se apresentam as diferenças entre o processo de pseudomorfose e o de imbricação dos meios artísticos, segundo o filósofo.s: This article presents a comparison of Gotthold E. Lessing’s theory of signs, as found in his Laocoön: an essay on the limits of painting and poetry, and Theodore W. Adorno’s two essays on the relationship between music and painting. Our aim is to point out the decisive influence of German classical aesthetics on Adorno’s post-war aesthetics. Specifically, we discuss how Lessing’s theory functions as a framework for Adorno’s dialectical assessment of the formal specificity of artistic media and their possibilities of convergence in the context of the 1960’s avant-garde. In this context, we discuss the main implications of Adorno’s famous lecture of 1966, Art and the arts, which concerned the process of media convergence that intensified during the 1960’s, as well as the concepts of “overlapping” between artistic media and of “pseudomorphosis”.

Vector logic is a mathematical model of the propositional calculus in which the logical variables are represented by vectors and the logical operations by matrices. In this framework, many tautologies of classical logic are intrinsic identities between operators and, consequently, they are valid beyond the bivalued domain. The operators can be expressed as Kronecker polynomials. These polynomials allow us to show that many important tautologies of classical logic are generated from basic operators via the operations called Type I and Type (...) II products. Finally, it is described a matrix version of the Fredkin gate that extends its properties to the many-valued domain, and it is proved that the filtered Fredkin operators are second degree Kronecker polynomials that cannot be generated by Type I or Type II products.

This essay urges us to complement work on the philosophy and social science of race that has focused on the “visual” and “epistemic” dimension of racism with work on affect or what is here called the somatological dimensions of racism. The racist self hears race before he sees it. The racist self is convulsed by race before she experiences it as an epistemic affair. It is argued here that we dwell in the sound house of race. Before racism is chromocratic, (...) it is phonocratic. The technologies of the racist self are the technologies of racializing aurality and phonology. Racism brands us sonically. Race, it will be argued, is a sonic stigmata. More specifically, the focus will be on voice, accent, what here is called the prosody of race. The aim is make those racialized and racializing accents in philosophy resound, echo, and reverberate so that we can hear the prosody of race. The racist does not dwell in the silent chamber of the mind’s “I.” The viscera of racism dwells in the body our racist habits have domesticated. (shrink)

El artículo documenta y analiza las vicisitudes en torno a la incorporación de Hilbert de su famoso axioma de completitud, en el sistema axiomático para la geometría euclídea. Esta tarea es emprendida sobre la base del material que aportan sus notas manuscritas para clases, correspondientes al período 1894–1905. Se argumenta que este análisis histórico y conceptual no sólo permite ganar claridad respecto de cómo Hilbert concibió originalmentela naturaleza y función del axioma de completitud en su versión geométrica, sino que además (...) permite disipar equívocos en cuanto a la relación de este axioma con la propiedad metalógica de completitud de un sistema axiomático, tal como fue concebida por Hilbert en esta etapa inicial.The paper reports and analyzes the vicissitudes around Hilbert’s inclusion of his famous axiom of completeness, into his axiomatic system for Euclidean geometry.

In the five-year period 2005-2009, Brazil dramatically reduced carbon emissions by about twenty-five percent and at the same time maintained a stable economic growth rate of 3.5% annually. This combination of economic growth and emissions reduction is unique in the world. It was driven by a dramatic reduction in deforestation in the Amazonian forest and the Cerrado Savannah. This shift empowered the sustainability social forces in Brazil to the point that in December 2009 Congress passed a very progressive law internalizing (...) carbon constraints and promoting the transition to a low-carbon economy. The Article first analyzes the Brazilian position in the global carbon cycle and public policies since 2005, including the progressive shift in 2009 and the contradictory dynamic in 2010-2012. It then analyzes the potential for a transition to a low-carbon economy in Brazil and the impact on global climate governance. (shrink)

The objective of this article is to demonstrate how the historical debate between materialism and idealism, in the field of Philosophy, extends, in new clothes, to the field of Quantum Physics characterized by realism and anti-realism. For this, we opted for a debate, also historical, between the realism of Albert Einstein, for whom reality exists regardless of the existence of the knowing subject, and Niels Bohr, for whom we do not have access to the ultimate reality of the matter, unless (...) conditioning it to the existence of an observer endowed with rationality, position adopted in the Interpretation of Complementarity – posture that was expanded in 1935 when Bohr assumed a “relationalist” conception, according to which the quantum state is defined by the relationship between the quantum object and the entire measuring device. This is an extremely important debate, as it further consolidates the results of nascent Quantum Mechanics, guaranteeing Bohr the leadership of the orthodoxy based on the interpretation of complementarity. Here, when dealing with Quantum Theory, we will not make any distinction between the terms Quantum Physics, Quantum Theory or Quantum Mechanics. The entire discussion will be held under the name “Quantum Theory”. Theory that tries to analyze and describe the behavior of physical systems of reduced dimensions, close to the sizes of molecules, atoms and subatomic particles. We hope that the reader will appreciate the genius of these two titans in this field of Physics when they magnificently formulate the arguments that support the object of their defenses. (shrink)

By the beginning of the 19th century Hegel's dialectic turned contradiction (conceived as unity of a concept with its determined negation) into distinguished inference. In the course of 20th century a family of systems known as "paraconsistent" formalized dialectical logic according to the contemporary paradigm of inference, oriented to truth-preserving, and not powered anymore solely by contradiction. In this way, nevertheless, Hegel's idea of logic as unfolding of concepts ordered by degree of "determination" reached at every step of the process, (...) was put aside. We attempt to recover the importance of that idea for the hegelian concept of "logical necessity", pointing out in addition that it may well play the role of an order relation for dialectical inference.

Me propongo aquí una reflexión sobre la crisis del humanismo que afecta profundamente a la sociedad y la cultura contemporáneas en todas sus dimensiones. De un modo falsamente optimista, se ha opuesto a esta crisis la figura de un post humanismo triunfante, resultado de los desarrollos de la tecnología contemporánea y sus posibilidades de intervención en el cuerpo y el alma del hombre.

ABSTRACT This is a brief introduction to a special section on the work of Achille Mbembe.

En este artículo se discute el reciente libro de Jürgen Habermas, Die Zukunft der menschlichen Natur. Auf dem Weg zu einer liberalen Eugenik (Suhrkamp Verlag, 2001). Se presta especial atención al argumento central relacionado con los efectos negativos que podría tener la aceptación general de la clonación y el diagnóstico génico preimplantacional (DGP) sobre la autocomprensión moral y política de las generaciones presentes y futuras. La discusión continúa con una crítica a los argumentos centrales de Habermas contra el DGP, y (...) desarrolla al menos dos razonamientos que están en armonía con su defensa general de la democracia procedimental y la moral deontológica. Se apela a Peter Singer y John Rawls para desarrollar argumentos que no se oponen ni al DGP ni a la ingeniería genética y que, no obstante, están totalmente de acuerdo con el espíritu de la modernidad política, tal y como lo defiende y define Habermas. La conclusión insta a una crítica de las biotecnologías desencadenadas por la revolución de la información que tenga un carácter menos moralizante y más político-económico. (shrink)
