Las micotoxinas son metabolitos fúngicos secunda­rios que pueden ejercer un efecto tóxico tanto en el hombre como en los animales debido, principalmente, a su exposición a través de los alimentos. La presencia de estos compuestos ha sido demostrada en una amplia variedad de materias primas, alimentos y piensos, en los que lo habitual es encontrar de for­ma frecuente una contaminación múltiple por diferentes mico­toxinas, en pequeñas cantidades, lo que puede generar efectos tóxicos subcrónicos, así como bioacumulación. Este artículo revisa los (...) principales elementos que configuran la problemática de las micotoxinas para el hombre y los animales, y aborda los retos de futuro que se plantean en el estudio de las micotoxinas, entre los que destacan el efecto que el cambio climático puede tener sobre el patrón de contaminación por micotoxinas en los alimentos, el descubrimiento creciente de nuevas micotoxinas en formas modificadas, la evaluación de la coexistencia de estas to­xinas y otros contaminantes, y las formas para detectar e intentar eliminar estos compuestos tóxicos de los alimentos.

Se estudian las reacciones de los primeros pensadores cristianos frente a la astrología, los antecedentes clásicos en que se basaron, y el posterior aprovechamiento de los símbolos y arquetipos astrológicos por la filosofía y literatura del humanismo cristiano.

La lectura plotiniana de la sincronicidad entre astros y hechos humanos en vez de la lectura causa-efecto de la astrología judiciaria tradicional fue la visión más seguida por el humanismo. Las estrellas no representan poderes en sí mismos sino como símbolos o signos. El hombre sabio, y así lo entendieron también los humanistas neoplatónicos, es aquél que sabe interpretar los símbolos desentrañando el sentido de la simpatía o analogía universales. El poder simbólico, por basarse en una inspiración abierta más que (...) en el raciocinio lógico, entronca con otros lenguajes simbólicos, incluido el de la literatura, al que presta numerosos recursos.

Sobre la base de las teorías de la causalidad de Salmon y Dowe es posible construir un argumento sencillo para un fisicismo fuerte. Pariendo del "dictum de Alexander", "ser es tener poderes causales" se puede concluir que, en lo tocante a propiedades, no puede haber en el mundo más que magnitudes físicas, pues sólo ellas entran en relaciones causales. Este argumento, sin embargo, es demasiado simple; en este artículo analizo una manera mas sutil y convincente de apoyar un fisicismo fuerte (...) con las teoría de Cantidades Conservadas (QC) de Salmon y Dowe.

En la literatura filosófica de las últimas décadas, existen numerosos argumentos orientados a demostrar que las propiedades fenoménicas, los qualia, no son integrables en el mundo natural. En este trabajo se sugiere que una gran familia de ellos, los basados en una simple distinción no especificada entre las propiedades naturales y las propiedades fenoménicas, carece de la fuerza necesaria para apoyar las intuiciones dualistas.

The by now famous exclusion problem for mental causation admits only one possible solution, as far as I can see, namely: that mental and physical properties are linked by a vertical relation. In this paper, starting from what I take to be sensible premises about properties, I will be visiting some general relations between them, in order to see whether, first, it is true that some vertical relationship, other than identity, makes different sorts of causation compatible and second, whether physical (...) and mental properties can be pairs of such relationship.

ABSTRACT: According to a model defended by some authors, dispositional predicates, or concepts, can be legiti- mately used in causal explanations, but such a use is not necessary. For every explanation couched in dispo- sitional terms, there is always a better, and complete, explanation that makes use of a different vocabulary, that of categorial bases. In what follows, I will develop this view, and then argue that there is a kind of use of dispositions in explanations that does not fall (...) within this model. That is, I will argue that we would miss some explanations if we were to forsake dispositional concepts and dispositional explanations. (shrink)

We aimed to conduct a scoping review to assess the profile of retracted health sciences articles authored by individuals affiliated with academic institutions in Latin America and the Caribbean (LAC). We systematically searched seven databases (PubMed, Scopus, Web of Science, Embase, Medline/Ovid, Scielo, and LILACS). We included articles published in peer‐reviewed journals between 2003 and 2022 that had at least one author with an institutional affiliation in LAC. Data were collected on the year of publication, study design, authors' countries of (...) origin, number of authors, subject matter of the manuscript, scientific journals of publication, retraction characteristics, and reasons for retraction. We included 147 articles, the majority being observational studies (41.5%). The LAC countries with the highest number of retractions were Brazil (n = 69), Colombia (n = 16), and Mexico (n = 15). The areas of study with the highest number of retractions were infectology (n = 21) and basic sciences (n = 15). A retraction label was applied to 89.1% of the articles, 70.7% were retracted by journal editors, and 89.1% followed international retraction guidelines. The primary reasons for retraction included errors in procedures or data collection (n = 39), inconsistency in results or conclusions (n = 37), plagiarism (n = 21), and suspected scientific fraud (n = 19). In conclusion, most retractions of scientific publications in health sciences in LAC adhered to international guidelines and were linked to methodological issues in execution and scientific misconduct. Efforts should be directed toward ensuring the integrity of scientific research in the field of health. (shrink)

Characterizations of autism include multiple references to rigid or inflexible features, but the notion of rigidity itself has received little systematic discussion. In this paper we shed some light on the notion of rigidity in autism by identifying different facets of this phenomenon as discussed in the literature, such as fixed interests, insistence on sameness, inflexible adherence to routines, black-and-white mentality, intolerance of uncertainty, ritualized patterns of verbal and non-verbal behavior, literalism, and discomfort with change. Rigidity is typically approached in (...) a disjointed fashion (i.e., facet by facet), although there are recent attempts at providing unifying explanations. Some of these attempts assume that the rigidity facets mainly relate to executive functioning: although such an approach is intuitively persuasive, we argue that there are equally plausible alternative explanations. We conclude by calling for more research on the different facets of rigidity and on how they cluster together in the autistic population, while suggesting some ways in which intervention could benefit from a finer-grained view of rigidity.

RESUMEN Las concepciones de salud mental son variadas y se han ido sucediendo de manera que cada una ha ido aportando nuevos matices a las anteriores, generando una nueva visión cada vez, donde las necesidades de la propia sociedad, han ido conformando una conceptualización de la salud mental de acuerdo con el contexto histórico, la disciplina y su modelación según las exigencias y particularidades de la sociedad y la cultura vigentes. Por consiguiente, se hace necesario replantear los conceptos desde los (...) que se interpreta la idea de salud mental, si guardan o no relación con definiciones universales o a concepciones construidas a partir de los diferentes planteamientos de salud-enfermedad. En consecuencia, es importante el aporte que se puede realizar desde la investigación para llegar a una construcción del concepto de Salud Mental que considere la multidisciplinariedad. Bajo esta perspectiva, se contextualiza el concepto de salud mental desde lo multidisciplinario. ABSTRACT There are several mental health conceptions which have been followed by others in such a way that each one of them has contributed to the previous ones, generating a different view each time, where the needs of society itself have made a conceptualization of mental health according to the historical context, discipline and model according to the requirements and particular features of society and the current culture. Therefore, it’s necessary to rethink the concepts from which the idea of mental health is interpreted, if it’s related to universal definitions or not, or to conceptions made from different approaches on health-disease. As a result, the contributions that can be made from research to achieve the construction of a multidisciplinary Mental Health concept are important. From this perspective, the concept of mental health is contextualized from a multidisciplinary point of view. (shrink)

RESUMEN Introducción: Son escasos los servicios en salud mental dentro del contexto escolar que permitan una integración intersectorial para superar la brecha de falta de asistencia en salud mental en la población infanto - juvenil, aun cuando, es en la escuela donde se detectan mayoritariamente los problemas de salud mental. Objetivo: Comentar el uso de servicios de salud mental en el ambiente escolar en relación con los trastornos mentales y trastornos subumbrales. Método: El presente resultado se obtiene a partir del (...) “Estudio de Prevalencia Comunitaria de Trastornos Psiquiátricos y Utilización de Servicios de la Población Infanto-Juvenil Chilena”. La muestra estuvo representada por sujetos entre 4 y 18 años. La información sobre el uso de servicio de salud mental se recogió con una versión modificada de la Escala Service Assesment for Children and Adolescent. Se realizó un modelo de regresión logística para analizar cinco áreas del uso de servicios en el ambiente escolar, las cuales se correlacionaron con diagnósticos de trastorno mentales y trastorno subumbral de ansiedad, disruptivo y depresión en el último año. Resultados: Las escuelas se enfrentan a grandes desafíos sobre cómo proporcionar apoyo efectivo de salud mental para los estudiantes, que presentan algún tipo de trastorno mental o trastorno subumbral. Discussión: Las instituciones educativas requieren ser visualizadas como una entidad que podría satisfacer las necesidades que se advierten de manera urgente en atención, prevención y promoción de problemas mentales en la población infanto- juvenil, si se vinculan de forma más directa con los servicios de salud mental. ABSTRACT Introduction: Mental health services are scarce within the school context that allow intersectoral integration to overcome the gap in mental health care in the child and adolescent population, being the school where mental health problems are mostly detected. Objective: to know the use of mental health services in the school environment in relation to mental disorders and subthreshold disorders. Method: The present secondary study is carried out from the "Study of Community Prevalence of Psychiatric Disorders and Utilization of Services of the Chilean Child-Youth Population". The sample was represented by subjects between 4 and 18 years old. Information on the use of mental health service was collected with a modified version of the Service Assessment Scale for Children and Adolescents. A logistic regression model was performed to analyze five areas of the use of services in the school environment, which were correlated with diagnoses of mental disorders and subthreshold anxiety, disruptive and depression disorder in the last year. Results: Schools face great challenges on how to provide effective mental health support for students, who present some type of mental disorder or subthreshold disorder. Discusion: Educational institutions need to be visualized as an entity that could meet the needs that are urgently noticed in attention, prevention and promotion of mental problems in the child and adolescent population, if it is linked more directly with health services.

Los desafíos que el Sínodo de la Amazonía presenta a la teología son trabajados en el horizonte de la pregunta por el estatuto epistemológico de la teología, a partir del uso de algunas metáforas empleadas por los textos del Sínodo. En este trabajo se requiere asumir una clave de lectura intertextual y un método que justifique la centralidad de las metáforas y su dinamismo de préstamo con relación a la fundamentación teológica. Las metáforas empleadas por los documentos sinodales dan qué (...) pensar a la teología con relación a su constitución interna. Le abren el camino para comprenderse de otra manera. Ese es el caso de: la eclesiología, lo propio del lenguaje teológico, las conversiones y actitudes para el quehacer de la teología, el lugar de la ritualidad y el valor de lo local con relación al intellectus del misterio y al depósito de la fe, la interculturalidad y la sinodalidad, entre otros.

This paper presents a systematic investigation of fuzzy Galois connections in the sense of R. Bělohlávek [1], from the point of view of enriched category theory. The results obtained show that the theory of enriched categories makes it possible to present the theory of fuzzy Galois connections in a succinct way; and more importantly, it provides a useful method to express and to study the link and the difference between the commutative and the non-commutative worlds.

In the present study we asked whether it is possible to decode personality traits from resting state EEG data. EEG was recorded from a large sample of subjects (n=289) who had answered questionnaires measuring personality trait scores of the 5 dimensions as well as the 10 subordinate aspects of the Big Five. Machine learning algorithms were used to build a classifier to predict each personality trait from power spectra of the resting state EEG data. The results indicate that the five (...) dimensions as well as their subordinate aspects could not be predicted from the resting state EEG data. Finally, to demonstrate that this result is not due to systematic algorithmic or implementation mistakes the same methods were used to successfully classify whether the subject had eyes open or closed. These results indicate that the extraction of personality traits from the power spectra of resting state EEG is extremely noisy, if possible at all. (shrink)

Automatic public malware analysis services provide controlled, isolated and virtual environments to analyse malicious software samples. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic PMAS, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis (...) environments; the lower the unlikeability of these features, the easier for us to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal. (shrink)

An essential requirement for increasing human confidence in computer systems is knowing an event’s origin. Therefore, it is necessary to have an efficient method to record such information. It is especially challenging in robotics, where unexpected behaviours can have unpredictable consequences, endangering the interests of people or even their safety. Furthermore, to analyse an incident’s cause or anticipate future behaviours, we must identify the events that cause a specific action. Although it is common to use logging systems for such purposes, (...) issues such as partial recording of events, unhelpful data or the impact on robot performance suggest conceiving new accountability solutions that assist when determining the responsible entities or the provenance of specific information. This paper presents a general-purpose approach to developing an accountability system for autonomous robots. It consists of four main components: a system event logger, a message producer, a distributed event streaming platform and a database. Our proposal is completely decoupled from the monitored system and allows real-time analysis, improving flexibility, besides system protection and transparency. Finally, the need to reduce the impact of the audit process and logging tasks on robot performance has promoted the development of different assessment scenarios to determine the best strategy for providing accounting services.

Clinical practices are considered one of the cornerstones in nurses' education. This study provides a framework to determine how factors in the academic environment, influence nursing student's satisfaction with their practices. A cross-sectional analytical study was conducted in a convenience sample of 574 nursing students at a private university in Valencia, during the 2016/2017 academic year, 79% were women. Two statistical methodologies were used for data analysis: hierarchical regression models and fuzzy sets qualitative comparative analysis. The HRM indicate that the (...) students' mean score influences all dimensions of satisfaction. Furthermore, in the fsQCA, the type of service and center, as well as the type of management, the preference in the choice of the practice center and the number of students per period per clinical educator influence satisfaction with clinical practices. These results could be used to understand how academic factors influence nursing students' satisfaction with their clinical practices and to create intervention programmes that improve it. This will help prepare students to be the future nursing workforce. (shrink)
