The geometric system of deduction called N-Graphs was introduced by de Oliveira in 2001. The proofs in this system are represented by means of digraphs and, while its derivations are mostly based on Gentzen's sequent calculus, the system gets its inspiration from geometrically based systems, such as the Kneales' tables of development, Statman's proofs-as-graphs, Buss' logical flow graphs, and Girard's proof-nets. Given that all these geometric systems appeal to the classical symmetry between premises and conclusions, providing an intuitionistic version of (...) any of these is an interesting exercise in extending the range of applicability of the geometric system in question. In this article we produce an intuitionistic version of N-Graphs, based on Maehara's LJ' system, as described by Takeuti. Recall that LJ' has multiple conclusions in all but the essential intuitionistic rules, e.g., implication right and negation right. We show soundness and completeness of our intuitionistic N-Graphs with respect to LJ'. We also discuss how we expect to extend this work to a version of N-Graphs corresponding to the intuitionistic logic system FIL (Full Intuitionistic Logic) of de Paiva and Pereira and sketch future developments.

In their attention to patients of different specialties, health personnel are the most vulnerable to contagion, which has been evidenced by the COVID-19 pandemic. The working conditions or factors for biosafety practices in health personnel worldwide will make it possible to detect the necessary and less treated lines of investigation, deficiencies and to draw up lines of work for their solution. It should be noted that it is estimated that 2.78 million workers die because of occupational accidents and 374 million (...) injuries caused by work are reported, thus increasing absenteeism, the risk of contracting a disease in the workplace has become more latent and 4% of the world's GDP is occupied by diseases. The objective of this study was to analyze the evidence that exists regarding the conditioning factors for the practice of biosafety in health personnel. The methodology: where a descriptive systematic review was performed with the search of databases in Scopus selected articles from 2019 - 2023 in English and Spanish languages. The results indicate that with regard to the conditioning factors of Biosafety practice, it is evident that of the 400 articles 50 mention that it is important to know how to do, 45 mention that it is important not only the training but also the equipment for these practices to be favorable, also 31 of the articles refer to that in COVID-19 period the infections among health personnel were due to the reuse of personal protective equipment.

Stress is a health problem that affects today's society, it is reflected in the degree of reaction to events or academic situations faced by the university student. The level of academic stress was analyzed according to sociodemographic factors in university students in a period of confinement due to COVID-19. 525 randomly chosen students from private and licensed universities in the city of Arequipa participated, an instrument was used to assess academic stress consisting of 21 items that measure stressors, symptoms, and (...) coping strategies. The results show that students have a moderate academic stress level with a tendency to be severe, it´s caused by the overload of academic work, the form of evaluation, and the type of work that teachers ask for, thus affecting their health due to the presence of somatic symptoms that affect students at the biopsychosocial level. Keywords: Academic stress, university students, sociodemographic factors. (shrink)

El objetivo de este trabajo es teorizar el andamiaje integrado por las categorías de modos de apropiación de lo real, formas de la conciencia y contemplación estética, construida con referentes kantianos, hegelianos y marxistas. Con base en un esquema de investigación, los escritos más representativos fueron revisados y fichados en una base de datos; el fichero fue codificado y redactado el texto final. Se encontró que la conciencia individual se constituye con referentes de diferentes modos de apropiación de lo real (...) adquiriendo una forma determinada: empírica, mágico-religiosa, artística o teórica. A cada modo de apropiación corresponde una forma de conciencia y un determinado tipo de experiencia plena pero, la presencia de referentes de distintos modos de apropiación, permite que el mismo sujeto establezca experiencias de distinto tipo.

El duelo es un proceso psicológico duro de sobrellevar ante la muerte por la aparición del Covid-19 en el Perú. Cuando las personas infectadas morían a consecuencia de la infección, eran incineradas por cuenta del hospital, y a los familiares se les entregaba una caja pequeña en la que se les decía que estaban las cenizas de su difunto. Las entrevistas realizadas a niños de 11 años de edad, padres de familia y psicólogos de hospitales; revelaron cuadros de ansiedad o (...) angustia, debido al temor generalizado. Los factores de protección social y escolar fueron poco sostenibles para sobrellevar la pena. (shrink)

Plagiarism is a serious, yet widespread type of research misconduct, and is often neglected in developing countries. Despite its far-reaching implications, plagiarism is poorly acknowledged and discussed in the academic setting, and insufficient evidence exists in Latin America and developing countries to inform the development of preventive strategies. In this context, we present a longitudinal case study of seven instances of plagiarism and cheating arising in four consecutive classes of an Epidemiology Masters program in Lima, Peru, and describes the implementation (...) and outcomes of a multifaceted, “zero-tolerance” policy aimed at introducing research integrity. Two cases involved cheating in graded assignments, and five cases correspond to plagiarism in the thesis protocol. Cases revealed poor awareness of high tolerance to plagiarism, poor academic performance, and widespread writing deficiencies, compensated with patchwriting and copy-pasting. Depending on the events’ severity, penalties included course failure and separation from the program. Students at fault did not engage in further plagiarism. Between 2011 and 2013, the Masters program sequentially introduced a preventive policy consisting of: intensified research integrity and scientific writing education, a stepwise, cumulative writing process; honor codes; active search for plagiarism in all academic products; and a “zero-tolerance” policy in response to documented cases. No cases were detected in 2014. In conclusion, plagiarism seems to be widespread in resource-limited settings and a greater response with educational and zero-tolerance components is needed to prevent it. (shrink)

Large-scale data systems are increasingly envisioned as tools for justice, with big data analytics offering a key opportunity to advance health equity. Health systems face growing public pressure to collect data on patient “social factors,” and advocates and public officials seek to leverage such data sources as a means of system transformation. Despite the promise of this “data-driven” strategy, there is little empirical work that examines big data in action directly within the sites of care expected to transform. In this (...) article, I present a case study on one such initiative, focusing on a large public safety-net health system’s initiation of sexual orientation and gender identity data collection within the clinical setting. Drawing from ethnographic fieldwork and in-depth interviews with providers, staff, and administrators, I highlight three main challenges that elude big data’s grasp on inequality: provider and staff’s limited understanding of the social significance of data collection; patient perception of the cultural insensitivity of data items; and clinic need to balance data requests with competing priorities within a constrained time window. These issues reflect structural challenges within safety-net care that big data alone are unable to address in advancing social justice. I discuss these findings by considering the present data-driven strategy alongside two complementary courses of action: diversifying the health professions workforce and clinical education reform. To truly advance justice, we need more than “just data”: we need to confront the fundamental conditions of social inequality. (shrink)

Plagiarism is a prevalent form of academic dishonesty in the undergraduate instructional context. Although students engage in plagiarism with some frequency, instructors often do little to help students understand the significance of plagiarism or to create assignments that reduce its likelihood. This study reports survey, coding, and TurnItIn software results from an evaluation of an instructional activity designed to help students improve their understanding of plagiarism, the consequences of plagiarizing, strategies to help them engage in ethical writing, and key citation (...) elements. Results indicate students had a greater understanding of plagiarism, increased efficacy, and fewer instances of plagiarism as determined by TurnItIn plagiarism software after exposure to an instructional activity on plagiarism. Not surprisingly, when instructors prioritize academic honesty in their classrooms, train students on how to integrate others’ works, cite sources appropriately, and use plagiarism detection software, students are less likely to plagiarize. The discussion includes suggestions for instructors to help them create a plagiarism-free environment. (shrink)

Based on the literature on stakeholder management and family firm dynamics, this research analyses the relationship between three constructs: the identification of business families with their family firms, FFs’ orientation toward key non-family stakeholders, and the achievement of better economic performance. Data analyses from 374 family and non-family members of 173 Spanish FFs show that a high level of family identification with their firms affects the orientation of FFs toward key non-family stakeholders in setting corporate goals and that this orientation (...) will lead to higher economic performance only when it is built on family identification with the firm. Our results also show that the significance of both relationships changes with the degree of family involvement in the management of the FF. (shrink)

Este trabajo propone una lectura de los momentos de continuidad y diferencia que existen entre las propuestas de recuperación de la filosofía marxista de Th. W. Adorno y G. Lukács, prestando especial atención a la manera en la que ambos desarrollan su teoría de la cosificación y el fetichismo de la mercancía.

This book examines the concept of “ Neurosemantics”, a term currently used in two different senses: the informational meaning of the physical processes in the neural circuits, and semantics in its classical sense, as the meaning of language, explained in terms of neural processes. The book explores this second sense of neurosemantics, yet in doing so, it addresses much of the first meaning as well. Divided into two parts, the book starts with a description and analysis of the mathematics of (...) the brain, including computational units, representational mechanisms and algorithmic principles. This first part pays special attention to the neural architecture which has been used in developing models of neurosemantics. The second part of the book presents a collection of models, and describes each model reproducing specific aspects of the semantics of language. Some of these models target one of the core problems of semantics, the reference of nouns, and in particular of nouns with a strong perceptual characterization. Others address the semantics of predicates, with a detailed analysis of colour attributes. While this book represents a radical shift from traditional semantics, it still pursues a line of continuity that is based on the idea that meaning can be captured, and explained, by a sort of computation.

It is widely believed that the semantic function of an ordinary proper name (e.g. 'Aristotle') is inexplicable in terms of the semantic function of an ordinary definite description (e.g. 'the last great ancient philosopher'), given a Russellian analysis of the latter. This paper questions this belief by suggesting a possible semantic explication. In brief, I propose that an ordinary proper name is a mere placeholder for an arbitrary ordinary definite description true of a given individual. The proposal is set out (...) and justified in detail, as well as compared with both traditional description theories of ordinary proper names and the theory that an ordinary proper name just means its referent. I contend that the proposed theory is better than the former sort of theory, and at least as good as the latter one. (shrink)

The use of the journal impact factor (JIF) as a measure for the quality of individual manuscripts and the merits of scientists has faced significant criticism in recent years. We add to the current criticism in arguing that such an application of the JIF in policy and decision making in academia is based on false beliefs and unwarranted inferences. To approach the problem, we use principles of deductive and inductive reasoning to illustrate the fallacies that are inherent to using journal (...) based metrics for evaluating the work of scientists. In doing so, we elaborate that if we judge scientific quality based on the JIF or other journal based metrics we are either guided by invalid or weak arguments or in fact consider our uncertainty about the quality of the work and not the quality itself.

El propósito de este artículo es prestar atención a la evolución de la lectura que hace Adorno de la fenomenología husserliana para abordar algunos de los problemas fundamentales que determinarán la formación materialista de su filosofía. Se pretende trazar la génesis de su pensamiento materialista desde su temprana afinidad con la obra de Cornelius, hasta los aspectos fundamentales de su filosofía de los años treinta.

RESUMENEl propósito de este artículo es investigar la evolución de la lectura que hace Adorno de Kierkegaard para presentarla como un tema central en la formación de su filosofía materialista. Kierkegaard, la construcción de lo estético anticipa en buena medida algunas de las ideas importantes de sus obras posteriores. Y es que si bien critica la ruptura de la dialéctica entre sujeto-objeto que tiene lugar en Kierkegaard, ambos van a coincidir en su ataque al idealismo a través de la crítica (...) inmanente.PALABRAS CLAVECRÍTICA INMANENTE, DIALÉCTICA, COMUNICACIÓN, MATERIALISMOABSTRACTThe main goal of this article is to investigate the evolution of Adorno’s reading of Kierkegaard to present it as a central theme for the formation of his own materialistic philosophy. His work Kierkegaard: Construction of Aesthetic anticipates a good deal of his later work. While he criticizes Kierkegaard for breaking off the subject-object dialectic, they converge in their attacks on the concept of idealism through the immanent critique.KEY WORDSIMMANENT CRITIQUE, DIALECTIC, COMMUNICATION, MATERIALISM.

In this paper we defend structural representations, more specifically neural structural representation. We are not alone in this, many are currently engaged in this endeavor. The direction we take, however, diverges from the main road, a road paved by the mathematical theory of measure that, in the 1970s, established homomorphism as the way to map empirical domains of things in the world to the codomain of numbers. By adopting the mind as codomain, this mapping became a boon for all those (...) convinced that a representation system should bear similarities with what was being represented, but struggled to find a precise account of what such similarities mean. The euforia was brief, however, and soon homomorphism revealed itself to be affected by serious weaknesses, the primary one being that it included systems embarrassingly alien to representations. We find that the defense attempts that have followed, adopt strategies that share a common format: valid structural representations come as “homomorphism plus X”, with various “X”, provided in descriptive format only. Our alternative direction stems from the observation of the overlooked departure from homomorphism as used in the theory of measure and its later use in mental representations. In the former case, the codomain or the realm of numbers, is the most suited for developing theorems detailing the existence and uniqueness of homomorphism for a wide range of empirical domains. In the latter case, the codomain is the realm of the mind, possibly more vague and more ill-defined than the empirical domain itself. The time is ripe for articulating the mapping between represented domains and the mind in formal terms, by exploiting what is currently known about coding mechanisms in the brain. We provide a sketch of a possible development in this direction, one that adopts the theory of neural population coding as codomain. We will show that our framework is not only not in disagreement with the “plus X” proposals, but can lead to natural derivation of several of the “X”. (shrink)

El sacrificio humano es una imagen frecuente en las religiones antiguas, concretamente en la griega, y su estudio ha levantado numerosos enfrentamientos entre corrientes historiográficas distintas. Uno de los casos más sobresalientes es del culto a Zeus en el Monte Liceo, que aquí analizamos. Las fuentes literarias reflejan la creencia de los griegos en estos sacrificios humanos, así que podemos decir que los sacrificios fueron reales porque fueron usados para construir paisaje y, por lo tanto, realidad.

In recent years, a number of different disciplines have begun to investigate the fundamental role context appears to play in a number of cognitive phenomena. Traditionally, linguistics, and the fields of communication and pragmatics in particular, have been the areas that have focused the most on contextual effects. Context has increasingly been studied for its role in influencing mental concepts, for some scholars being considered constitutive for most – if not all – concepts. Cognitive neuroscience is now starting to consider (...) in a systematic way how context interacts with neural responses, although this research is still scattered and concentrated in a small number of specific cases only. In this chapter, we attempt to tie these three levels together, since only from their integration can a comprehensive explanation of how context affects cognition be constructed. The way context drives language comprehension depends on the effects of context on the conceptual scaffolding of the listener, which in turn, is the result of his neural responses in combination to context. These neural responses derive from learning throughout the history of experiences of the individual, and the association between possible contexts and heard utterances. The road we take to accomplishing the multi-level integration between what appear to be distant domains, is a computational one. This approach meets with the mechanistic framework of explanation, which is currently held as the most appropriate way of approaching cognitive phenomena that is often characterized by a multiplicity of levels, as is the case with context. The core underlying concept of the neurocomputational framework here proposed, is an account of neural representation, based on structural similarity. Structural representations are still the best option on the market in cognitive science, but in their traditional form, derived from classical measurement theory, are affected by a number of serious drawbacks, including not being able to account for context. We suggest a different account of structural similarity, one informed by current neuroscience, where the homomorphic relations required for structural similarity are derived from neural population coding. In a preliminary mathematical sketch, we indicate how this approach can construct neural aggegations that are sensitive to context. (shrink)

The Syllabus as Curriculum: A Reconceptualist Approach by Samuel D. Rocha. The review examines the central tenets of Rocha’s book, namely that the syllabus is an object which is made, and that his phenomenological attention to the syllabus as such bears the poetic pledge and possibility of curriculum. Rocha considers the syllabus, working within the reconceptualist tradition of the curriculum field, as correspondence, essay, and outline, and describes the way it humbly gives itself to teachers and students as an invitational (...) object. Using a presentative method and rooted in the humanities, Rocha additionally presents and explores three interrelated and analogical demands of the syllabus, namely love, art, and order, contributing to an ongoing and complicated conversation within curriculum studies and philosophy of education.

Objective: To measure the stability of life-sustaining treatment preferences amongst older people and analyse the factors that influence stability. Design: Longitudinal cohort study. Setting: Primary care centres, Granada (Spain). Eighty-five persons age 65 years or older. Participants filled out a questionnaire with six contexts of illness (LSPQ-e). They had to decide whether or not to receive treatment. Participants completed the questionnaire at baseline and 18 months later. Results: 86 percent of the patients did not change preferences. Sex, age, marital status, (...) hospitalisation, and self-perception of health and pain did not affect preferences. Morbidity and the death of a relative did. Conclusion: Stability of preferences of older persons in relation to end-of-life decisions seems to be more probable than instability. Some factors, such as the death of a relative or the increase in morbidity, can change preferences. These findings have implications for advance directives (ADs) and advance care planning. (shrink)
