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.

La arqueología ha revelado recientemente la existencia de una importante revitalización urbana en Córdoba durante el Califato Almohade, apenas tratada hasta ahora por la historiografía, centrada principalmente en su pasado omeya. Por un lado, se ha observado una importante inversión del poder almohade en elementos defensivos y palatinos, acaso por tratarse en estas fechas de un centro fundamental en la conceptualización histórica de al-Andalus y en la lucha contra los reinos cristianos; por otro, se ha documentado un importante crecimiento orgánico (...) y privado extramuros. Todo ello coincidió con su elección como capital andalusí en 557/1162 por ‘Abd al-Mu’min, lo que suponía un hito fundamental para la legitimación de su nuevo califato. Tras su muerte pocos meses después, Abū Ya‘qūb Yūsuf hizo regresar la corte a Sevilla, creando un importante cambio de rumbo en la política almohade que no afectó al resurgir urbano de la antigua sede omeya. En realidad, Córdoba seguiría muy presente en la mentalidad colectiva andalusí durante el gobierno almohade, manteniéndose como referente principal del esplendor pasado y como núcleo esencial de la tradición mālikī.

Se analiza la apuesta ontológica de Arturo Escobar a partir de dos formas en las que esta se expresa, para vislumbrar los alcances y limitaciones de esta concepción ontológica. La primera concepción radica en lo que el autor denomina ontología relacional y la segunda versa en la llamada ontología política. El texto está dividido en cuatro apartados, el primero introduce al lector a lo que representa la pregunta por el ser, haciendo hincapié en Martin Heidegger. El segundo expone brevemente el (...) contexto que se puede evidenciar en la apuesta académica del antropólogo colombiano a través del giro ontológico, desarrollado desde la antropología, en el que se destaca una crítica al paradigma occidental dualista naturaleza/cultura y, a su vez, de la teoría decolonial que denuncia a la Modernidad y la vigencia de la colonialidad de ser, para así poder comprender la propuesta de la ontología relacional de Escobar. El tercer apartado expresa desde las categorías de territorio y pluriverso una premisa fundamental: pensar lo político presupone una ontología, es decir, una visión de mundo sobre lo que es y está, de esta manera se articula el proyecto de la ontología desde la relacionalidad con luchas que reivindican los mundos y los derechos de las comunidades; en el cuarto y último apartado se exponen los alcances y límites de la ontología de Escobar, así como caminos posibles para considerar en investigaciones futuras.

_The Power of Religion in the Public Sphere_, co-edited by Eduardo Mendieta and Jonathan VanAntwerpen, represents a rare opportunity to experience a diverse group of preeminent philosophers confronting one pervasive contemporary concern: what role does, or should, religion play in our public lives? Reflecting on her recent work concerning state violence in Israel-Palestine, Judith Butler explores the potential of religious perspectives for renewing cultural and political criticism, while Jürgen Habermas, best known for his seminal conception of the public sphere, (...) thinks through the ambiguous legacy of the concept of "the political" in contemporary theory. Charles Taylor argues for a radical redefinition of secularism, and Cornel West defends civil disobedience and emancipatory theology. Eduardo Mendieta and Jonathan VanAntwerpen detail the immense contribution of these philosophers to contemporary social and political theory, and an afterword by Craig Calhoun places these attempts to reconceive the significance of both religion and the secular in the context of contemporary national and international politics.

The Cooperative Extension System serves as the conduit through which scientific knowledge generated by the 130 land-grant colleges and universities in the United States is translated and delivered directly to its constituents. Since its inception over 100 years ago, Extension has been integral in developing, delivering, and applying cutting-edge knowledge in agriculture and natural resources, youth development, family and consumer sciences, and community and rural development. Today, more than ever, Extension will need to lead the way in building and maintaining (...) sustainable partnerships across disciplines and with organizations at the local, state, and national levels to tackle complex issues considering diminishing resources. Bringing together leading and emerging scholars, this volume discusses how Extension is addressing issues and opportunities relevant to children, youth, families, and communities across the country both now and in the future. Topics include Extension's role in supporting childcare, social media use, entrepreneurship, rural communities, and underserved audiences. (shrink)

The purpose of this paper is to present a formalization of the language, semantics and axiomatization of justification logic in Coq. We present proofs in a natural deduction style derived from the axiomatic approach of justification logic. Additionally, we present possible world semantics in Coq based on Fitting models to formalize the semantic satisfaction of formulas. As an important result, with this implementation, it is possible to give a proof of soundness for $\mathsf{L}\mathsf{P}$ with respect to Fitting models.

This paper argues that epistemic errors rooted in group- or identity- based biases, especially those pertaining to disability, are undertheorized in the literature on medical error. After sketching dominant taxonomies of medical error, we turn to the field of social epistemology to understand the role that epistemic schemas play in contributing to medical errors that disproportionately affect patients from marginalized social groups. We examine the effects of this unequal distribution through a detailed case study of ableism. There are four primary (...) mechanisms through which the epistemic schema of ableism distorts communication between nondisabled physicians and disabled patients: testimonial injustice, epistemic overconfidence, epistemic erasure, and epistemic derailing. Measures against epistemic injustices in general and against schema-based medical errors in particular are ultimately issues of justice that must be better addressed at all levels of health care practice.

In this paper we discuss the extent to which the very existence of substructural logics puts the Tarskian conception of logical systems in jeopardy. In order to do this, we highlight the importance of the presence of different levels of entailment in a given logic, looking not only at inferences between collections of formulae but also at inferences between collections of inferences—and more. We discuss appropriate refinements or modifications of the usual Tarskian identity criterion for logical systems, and propose an (...) alternative of our own. After that, we consider a number of objections to our account and evaluate a substantially different approach to the same problem. (shrink)

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)

Many authors have considered that the notions of paraconsistency and dialetheism are intrinsically connected, in many cases, to the extent of confusing both phenomena. However, paraconsistency is a formal feature of some logics that consists in invalidating the rule of explosion, whereas dialetheism is a semantical/ontological position consisting in accepting true contradictions. In this paper, we argue against this connection and show that it is perfectly possible to adopt a paraconsistent logic and reject dialetheism, and, moreover, that there are examples (...) of non-paraconsistent logics that can be interpreted in a dialetheic way.

Anti-exceptionalism about logic states that logical theories have no special epistemological status. Such theories are continuous with scientific theories. Contemporary anti-exceptionalists include the semantic paradoxes as a part of the elements to accept a logical theory.

This means that the logics in this hierarchy are also options to analyze the inferential patterns allowed in a language that contains its own truth predicate.

But even if the data are not enough to adopt one of these logics, there are other elements to evaluate the revision of classical logic.

In this note we shall argue that Milne’s new effort does not refute Truthmaker Maximalism. According to Truthmaker Maximalism, every truth has a truthmaker. Milne has attempted to refute it using the following self-referential sentence M: This sentence has no truthmaker. Essential to his refutation is that M is like the Gödel sentence and unlike the Liar, and one way in which Milne supports this assimilation is through the claim that his proof is essentially object-level and not semantic. In Section (...) 2, we shall argue that Milne is still begging the question against Truthmaker Maximalism. In Section 3, we shall argue that even assimilating M to the Liar does not force the truthmaker maximalist to maintain the ‘dull option’ that M does not express a proposition. There are other options open and, though they imply revising the logic in Milne’s reasoning, this is not one of the possible revisions he considers. In Section 4, we shall suggest that Milne’s proof requires an implicit appeal to semantic principles and notions. In Section 5, we shall point out that there are two important dissimilarities between M and the Gödel sentence. Section 6 is a brief summary and conclusion. (shrink)

Resumen: La tolerancia es un privilegio de los poderosos. Una persona puede tolerar sólo si tiene el poder para interferir con aquello que objeta. En este artículo analizaré las circunstancias en las que alguien tiene el poder para tolerar. Argumentaré que la respuesta debe incorporar consideraciones tanto prácticas como metafísicas. Específicamente, defenderé que alguien tiene el poder para tolerar cuando sus propiedades fundan tal poder en la situación práctica en que ella se encuentra, según es caracterizada por sus intereses prácticos. (...) Al hacerlo criticaré el análisis del mencionado poder realizado por Glen Newey. (shrink)

Academics are confronted with multiple and conflicting narratives as to what it is to be an academic. Their identities, however, are not entirely of their own making. Through a qualitative study, and deploying a social realist perspective, this paper analyses academic identities in Chile and attempts to locate the patterns of identity in the context of a marketised higher education system. The data were collected in both a state and a private university. The results suggest that distinct kinds of fragilities (...) may be emerging among Chilean academics (ontological and contractual fragilities). These two fragilities can be traced to the attendant structures of the university system at an institutional level (reputational fragility in the public sector and a branding fragility in the private sector). The paper concludes by observing that, although the power of the structures is considerable, there are still spaces for agentic responses. (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.

Who Comes After the Subject offers the most comprehensive overview to date of contemporary French thinking on the question of the "subject." Nineteen philosophers and critics offer diverse perspectives on the subject as it has manifested itself in our modern discourses: the subject of philosophy, of the State, of history, of psychoanalysis. Each contribution asks What has become of the subject? or What has the subject become? in the wake of its critiques and deconstructions .

En este breve comentario discuto algunos aspectos de la interpretación de la epistemología de Davidson que sugiere Willian Duica en su reciente libro. Luego de una presentación somera del libro me centro en tres asuntos centrales de la interpretación de Duica. En primer lugar, argumento que su lectura de la crítica de Davidson al dualismo esquema/contenido es muy restrictiva y deja abierta la posibilidad de un realismo directo empirista. En segundo lugar, argumento que en su lectura el propio Duica se (...) compromete inadvertidamente con un empirismo de este tipo y, de este modo, su interpretación entra en tensión con el coherentismo de Davidson. Finalmente, discuto algunos aspectos de la interpretación que hace Duica de la tesis davidsoniana de la triangulación. In this short comment I discuss some aspects of William Duica's interpretation of Davidson's epistemology in a recent book. After a brief review of the book, I focus on three central issues of Duica's interpretation. First, I argue that his reading of Davidson's criticism of the scheme/content dualism is too restrictive and leaves open the possibility of an empiricist direct realism. Second, I argue in his reading Duica inadvertently commits himself to an empiricism of this sort and, as a result, his interpretation is in tension with Davidson's own coherentism. Finally, I discuss some aspects of Duica's interpretation of Davidsonian triangulation. (shrink)

Transhumanism proposes human enhancement while regarding the human body as unfit for the future. This fulfills age-old aspirations for a perfect and durable body. We use “alienation” as a concept to analyze this mismatch between human aspirations and our current condition. For Hannah Arendt alienation may be accounted for in terms of earth- and world-alienation, as well as alienation from human nature, and especially from the given (“resentment of the given”). In transhumanism, the biological body is an impediment to human (...) accomplishment. At most, this movement accepts “clean” bodies, not bodies with excretions. We argue that real human bodies are valued in the event of giving birth, so a modified concept that Arendt proposed, natality, seems a suitable way to explore the dialectic alienation-reconciliation involving the body (Arendt’s “A child has been born unto us”), when re-read by some feminist scholars.

La investigación aborda el dilema que implica la relación entre economía y ética, el cual se deriva de la separación entre filosofía moral y economía positiva. Analizarlo a través de la teoría del bienestar permite acercarse a los preceptos de un cognitivismo ético o de psicología moral, mediante una propuesta distinta de individuo representativo. La finalidad es ofrecer algunos elementos para observar a la economía desde otra perspectiva, al estrechar los lazos teóricos con la ética.

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 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.

Situados en un progresivo traspaso de responsabilidades en la ejecución de los servicios sociales desde el Estado hacia actores no gubernamentales, aparece una demanda hacia el mismo Estado, el cual en lugar de simplemente declinar su labor, debiera de hecho expandir su regulación de modo de asegurar que la oferta social sea eficiente en satisfacer al ciudadano usuario en aquellos servicios prometidos por las políticas y programas sociales.
