The objective of this research is to develop accurate forecasting models for chlorophyll-α concentrations at various depths in El Mar Menor, Spain. Chlorophyll-α plays a crucial role in assessing eutrophication in this vulnerable ecosystem. To achieve this objective, various deep learning forecasting techniques, including long short-term memory, bidirectional long short-term memory and gated recurrent uni networks, were utilized. The models were designed to forecast the chlorophyll-α levels with a 2-week prediction horizon. To enhance the models’ accuracy, a sliding window method (...) combined with a blocked cross-validation procedure for time series was also applied to these techniques. Two input strategies were also tested in this approach: using only chlorophyll-α time series and incorporating exogenous variables. The proposed approach significantly improved the accuracy of the predictive models, no matter the forecasting technique employed. Results were remarkable, with |$\overline{\sigma}$| values reaching approximately 0.90 for the 0.5-m depth level and 0.80 for deeper levels. The proposed forecasting models and methodologies have great potential for predicting eutrophication episodes and acting as decision-making tools for environmental agencies. Accurate prediction of eutrophication episodes through these models could allow for proactive measures to be implemented, resulting in improved environmental management and the preservation of the ecosystem.

La Psicología de la Sustentabilidad (PS) estudia las problemáticas hídricas considerando la relación entre disponibilidad per cápita y consumo de agua. A partir de conceptos tales como; densidad poblacional, infraestructura hídrica y provisión de agua plantea tres estilos de vida relativos al almacenamiento de agua, la reparación de fugas y el consumo hídrico. La PS advierte que las relaciones causales entre las problemáticas hídricas y los estilos de vida son relevantes si se considera el Desarrollo Local Sustentable más que regional (...) y global. A medida que las problemáticas hídricas se intensifican, procesos actitudinales y de austeridad prevalecen sobre el dispendio de agua. En contraste, las situaciones hídricas en equilibrio con el consumo residencial facilitan el dispendio. La discusión alusiva a las problemáticas hídricas y los estilos de vida permitirá construir un sistema tarifario de consumo y delimitar las políticas públicas que se requerirán en el marco de la crisis de abastecimiento y distribución que se espera en los próximos años.

Quantum physics and the dialogue with religion The present paper has two main purposes. On the one hand, to introduce Pascual Jordan, an author little known in philosophy academic circles and better known in scientific ones. Jordan took part in the birth of quantum physics during the first half of the 20th century and worked side by side with Werner Heisenberg under Max Born’s direction to elaborate Matrix Mechanics, an essential contribution to the formal description of atom quantum structure. On (...) the other hand, I expose his personal contribution to the science and religion debate. In this regard, he found himself both in an unfavorable and a favorable position. Unfavorable, because Jordan stands far from such epistemological matters as scientific realism; favorable, because he took very seriously the discoveries of new rising physics, and was, thus, a committed realist when discussing scientific theories. Furthermore, he was a devoted Christian, which means that he has a realist stance on religion – the only valid choice for those who consider the relation between life and faith as indissoluble. His constitutive realism leads him to regard the relation between religion and science as an existential problem rather than as an academic one, and therefore, he dedicated a large part of his philosophical works to this subject.

The Mondragon Corporation, a group of cooperatives, is a thriving example of how cooperatives can succeed. The authors describe six features of the corporation and five 'successful cooperative actions' that they consider to be crucial in explaining its accomplishments. Both the specific features and the successful actions are contrasted with those of standard capitalist companies, to show how this case is unique in the field of corporate organization and management. Through a combination of democratic principles, the values of solidarity, and (...) strong competitiveness, Mondragon has simultaneously achieved both efficiency and equity and has become an alternative to the organizational and governance models of traditional capitalist firms.

Time and technology permeate the fabric of teamwork across a variety of settings to affect outcomes which have a wide range of consequences. However, there is a limited understanding about the interplay between these factors for teams, especially as applied to artificial intelligence (AI) technology. With the increasing integration of AI into human teams, we need to understand how environmental factors such as time scarcity interact with AI technology to affect team behaviors. To address this gap in the literature, we (...) investigated the interaction between the availability of intelligent technology and time scarcity in teams. Drawing from the theoretical perspective of computers are social actors and extant research on the use of heuristics and human–AI interaction, this study uses behavioral data from 56 teams who participated in a between-subjects 2 (intelligent assistant available × control/no intelligent assistant) × 2 (time scarcity × control/no time scarcity) lab experiment. Results show that teams working under time scarcity used the intelligent assistant more often and underperformed on a creative task compared to teams without the temporal constraints. Further, teams who had an intelligent assistant available to them had fewer interactions between members compared to teams who did not have the technology. Implications for research and applications are discussed. (shrink)

Para el transhumanismo, la humanidad es una etapa que, guiada por la evolución biológica, estuvo precedida por otras anteriores y a la que seguirán otras nuevas. Según el transhumanismo hemos de romper la inercia de causas ciegas que gobierna la evolución y, a través de la biotecnología, alcanzar lo que denominan una “vida mejor”. Los autores afines a esta corriente desarrollan sus propuestas negando la existencia de una naturaleza humana, pero sin abandonar la convicción de que resulta posible definir en (...) qué consiste una “vida mejor”. En este artículo analizamos la claridad y el rigor con la que presentan el fin último de su propuesta, la relación entre el fin y los medios planteados para alcanzarlo, y, finalmente, pondremos de manifiesto algunas inconsistencias derivadas de su rechazo de que la naturaleza humana pueda tener valor normativo.

The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as the (...) forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (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.

La bibliografía reporta amplitud en lo concerniente al campo de la edición de revistas científicas donde los avances científico tecnológicos aportaron una nueva dinámica. Las nuevas tecnologías de la información y la comunicación sirven de herramientas y han transformado radicalmente el escenario de la evaluación de la publicación científica. Variedad de perspectivas, instrumentos e indicadores impactan en los procesos de evaluación. El objetivo de este trabajo es ofrecer una valoración del proceso actual de evaluación de las publicaciones científicas seriadas. Los (...) procedimientos utilizados son la revisión bibliográfica, análisis de textos y síntesis de los hallazgos desde lo teórico. Se concluye que la publicación científica seriada ha pasado a ser, más que un proceso singular de la comunicación científica, el modo fundamental de evaluación de la calidad del trabajo científico, de ahí la importancia de tener claridad y propuestas propias de los indicadores de la evaluación. There is amplitude in bibliography, regarding the edition of scientific journals, where the scientific technological achievements that have been made in recent times have contributed with a new dynamic. The edition in digital format has its name due to the appearance of the new information and communication technologies. The recently emerged perspectives, instruments and indicators impact evaluation of publications processes and the accreditation in the higher education. The aim of this document is to offer an assessment on the current situation of the evaluation process of serialized scientific publications through the use of indicators. The text analysis and bibliographic review procedures were used to achieve the previous goal. In conclusion, the serialized scientific publications have become the main way quality of scientific research evaluation rather than a specific process of scientific communication. That is why is important to be certain of the combination of indicators for evaluating the scientific publications. (shrink)

For companies involved in the supply chain, proper warehousing management is crucial. Warehouse layout arrangement and operation play a critical role in a company’s ability to maintain and improve its competitiveness. Reducing costs and increasing efficiency are two of the most crucial warehousing goals. Deciding on the best warehouse layout is a remarkable optimization problem. This paper uses an optimization method to set bin allocations within an automated warehouse with particular characteristics. The warehouse’s initial layout and the automated platforms limit (...) the search and define the time required to move goods within the warehouse. With the help of historical data and the definition of the time needed to move goods, a mathematical model of warehouse operation was created. An optimization procedure based on the well-known Variable Neighbourhood Search algorithm is defined and applied to the problem. Experimental results demonstrate increments in the efficiency of warehousing operations. (shrink)

Despite abundant evidence associating CD38 overexpression and CD4 T cell depletion in HIV infection, no causal relation has been investigated. To address this issue, a series of mechanisms are proposed, supported by evidence from different fields, by which CD38 overexpression can facilitate CD4 T cell depletion in HIV infection. According to this model, increased catalytic activity of CD38 may reduce CD4 T cells’ cytoplasmic nicotin‐amide adenine dinucleotide (NAD), leading to a chronic Warburg effect. This will reduce mitochondrial function. Simultaneously, CD38's (...) catalytic products ADPR and cADPR may be transported to the cytoplasm, where they can activate calcium channels and increase cytoplasmic Ca2+ concentrations, further altering mitochondrial integrity. These mechanisms will decrease the viability and regenerative capacity of CD4 T cells. These hypotheses can be tested experimentally, and might reveal novel therapeutic targets. (shrink)

In this article, an attempt was made to identify the level of community social participation according to age, gender and the structural characteristics of the personal support networks in a population displaced by floods in the Colombian Caribbean. The research was based in a non-experimental methodology with an associative-relational strategy. An intentional non-probabilistic sample of 151 people affected by the winter wave in the south of the Department of Atlántico (Colombia) was selected. In total, the study included 42 males (27.8 (...) %) and 109 females (72.2 %) participants, with an average age of 37.48 (±14, Range 18 - 80) and average relocation time of 21.79 months (± 8.22, Range 5-36). The Arizona Social Support Interview Schedule (ASSIS) and Community Empowerment instruments were responded to with an instrument adapted from the leadership competence factor. The results show lower rates of intermediation in the older population, and the relationship between social participation and gender shows equally cohesive social support networks in men and women. This evidence is discussed to promote psychosocial interventions aimed to increase community engagement and empowerment of people that have experienced non-voluntary mobility processes. (shrink)

Resumen: El discurso de la economía ha transitado por una tensión entre pertenecer a una Ciencia Social y presentar rasgos prototípicos de una Ciencia Básica. Ahora bien, evidenciar esta hibridez desafía a los investigadores del lenguaje, sobre todo si estos textos son parte de la formación de un economista. Particularmente, el Informe de Política Monetaria no ha sido estudiado desde el punto de vista lingüístico, por lo que se busca observar, en un corpus de 45 textos, si el género IPOM (...) evidencia dicha tensión discursiva de la disciplina. Para lograr ese objetivo, se ha optado por una metodología basada en dos dimensiones: Contexto de Producción y Organización Retórico-Funcional. Tras el análisis, los hallazgos del corpus IPOM-2013 integradamente muestran que el género IPOM efectivamente evidencia dicha tensión con rasgos más características de la CB como es el uso de recursos matemáticos y, por otro lado, rasgos de la CS, asociados a la modalización del discurso en su macromovida central.: The discourse of economy has gone by a constant tension between belonging to a Social Science and present prototypical features of a Basic Science. However, evidence this hybridity poses a challenge for researchers of language, especially if these texts are part of the training of an economist. In particular, the Monetary Policy Report has not been studied from the linguistic point of view. In this context, this research search to answer the question whether the gender IPOM evidences such discursive tension of the discipline. To achieve this objective, it has opted for a methodology based on 2 dimensions: Production Context and Rhetorical-Functional Organization. After the analysis, the findings Integrally shows that the IPOM genre effectively demonstrates this tension with features more characteristic of the BS such as the use of mathematical resources and, on the other hand, SC traits, mainly associated to the modalization of the discourse in its central macromove.

Two aspects of the fine Flecha-Cruz paper can be usefully elaborated. The Mondragon cooperatives differ not only from capitalist firms but also from most other cooperatives in the doctrine of the 'priority of labor over capital' which means that the people working in any sort of cooperative will be members and will not be rented as employees. Also the Mondragon system of internal capital accounts solves the equity-structure problem that has plagued many modern cooperatives structured as non-profits or traditional (...) worker cooperatives with 'membership shares'.

El presente artículo pretende indagar en algunos tópicos relativos a las ideas de Marx y a las de Horkheimer presentes en la obra Teología de lo político de Clodovis Boff. En este análisis se observa una referencia explícita a la ideas del padre del marxismo donde Boff se acompaña con Marx, va más allá de Marx e incluso va contra Marx. Por otro lado, es posible identificar tres afinidades electivas que permiten suponer que la interpretación que Boff realiza del marxismo (...) deviene del padre de la teoría crítica, Max Horkheimer. The article below investigates topics related to Marx's and Horhkheimer's ideas as exposed in Theology of the Political by Clodovis Boff. The analysis shows a direct reference from Boff to the father of Marxism's ideas, going along, beyond and even against Marx. On the other hand, it is possible to identify three elective affinities that make us believe that his interpretation of Marx has its origin in the father of Critical Theory's ideas, Max Horkheimer.

RESUMEN El suicidio o el interfictium spinoziano es a simple vista una categoría marginal en el pensamiento de Spinoza. La vasta producción filosófica en torno a quien ha sido considerado como el filósofo de la "anomalía salvaje" o al mismo tiempo el pensador de los "afectos alegres" ignora, o en el mejor de los casos trata oblicuamente, las nociones de muerte y suicidio. La paradoja es total porque el rechazo hacia el pensamiento de la muerte contrasta con la profusa interpelación (...) a dicha categoría en su Ética. El propósito de este artículo es mostrar que la expresión negativa del suicidio, como pura imposibilidad y servidumbre respecto a causas externas es, sin embargo, menos literal y clara, cuando en su análisis se incorporan aquellos elementos centrales de su obra más emblemática. Libertad, Necesidad y Sustancia, entre otros, son conceptos que, desde el suicidio se tensionan mostrando los propios límites del orden geométrico esbozado por Spinoza. ABSTRACT Suicide or spinozian interfictium is at first sight a marginal category in Spinoza's thought. The vast philosophical production on who has been considered the philosopher of the "savage anomaly" or at the same time the "cheerful affects" thinker, ignores or, in the best-case scenario, obliquely addresses the notions of death and suicide. The paradox is complete because the rejection towards the thought of death contrasts with the profuse questioning of the aforesaid category in its Ethics. The goal of this article is to show that the negative expression of suicide, as pure impossibility and servitude with respect to external causes is however, less literal and clear when some central elements of its most emblematic work are incorporated in its analysis. Liberty, Need, and Substance, among others, are concepts that from suicide get tensioned showing the own limits of the geometric order insinuated by Spinoza. (shrink)

Reflections on Peirce’s theory of abduction have not been free of controversy, given the difficulty to determine clearly the nature and epistemic function of this inference. The article examines three ways of understanding the concept of abduction, developed by Peirce himself throughout his work. The main objective is to reconstruct the logical, methodological, and instinctive conception of this type of reasoning in order to establish the possibility of a theory of abduction.

The aim of this paper is to explore the peculiar case of infectious logics, a group of systems obtained generalizing the semantic behavior characteristic of the -fragment of the logics of nonsense, such as the ones due to Bochvar and Halldén, among others. Here, we extend these logics with classical negations, and we furthermore show that some of these extended systems can be properly regarded as logics of formal inconsistency and logics of formal undeterminedness.

En este trabajo, nos proponemos redefinir las posturas que toman parte en el debate entre realismo y antirrealismo científicos, dejando de concebirlas únicamente como doctrinas o teorías que describen cómo es el mundo. En cambio, acorde al camino iniciado por van Fraassen en The empirical stance, optamos por definirlas como stances: políticas, estrategias o perspectivas a partir de las cuales construimos creencias fácticas. Así, en primera instancia nos dedicamos a entender qué es una stance y cómo caracterizar esta noción. En (...) segundo lugar, exploramos metodologías y enfoques para tratar el realismo y el antirrealismo como stances, y, en esta clave, definirlos adecuadamente. Por último, examinamos el impacto de esta propuesta en la explicación de los acuerdos y desacuerdos en el debate, evaluando los grados de afinidad o distancia en las perspectivas en juego. (shrink)
