En los pueblos indígenas de México existen mecanismos de toma de decisión y participación que contribuyen al logro del bienestar común. Estos procesos constituyen parte del espacio público para resolver sus problemas y a través de ellos se reafirman la pertenencia e identidad que fortalecen las relaciones sociales, políticas, económicas y culturales de los miembros de la comunidad. La forma en que se manifiesta esta reafirmación es por medio de la participación en el trabajo comunitario, el sistema de cargos y (...) las asambleas comunitarias. Sin embargo, en los últimos años, con la intervención de las políticas públicas de los distintos órdenes de gobierno y la inclusión de estos pueblos en los procesos políticos, en la búsqueda de una mayor participación ciudadana y el ejercicio de sus derechos civiles en un contexto democrático, han modificado las reglas de convivencia afectando estos mecanismos que son la base de la estructura comunitaria.

The aim of this study was to evaluate the neuromuscular response to an agility and repeated sprint ability test according to the level of competition in futsal players. A total of 33 players from two elite teams and one amateur team participated in the study. The participants completed an agility t-test, a 30 m-speed test, and a RSA test. A countermovement jump test and a tensiomyography test of the rectus femoris and biceps femoris of both legs were carried out before (...) and after the tests. RSA test revealed better sprint times in elite players compared to amateurs in the seven bouts, as well as in the 30 m sprint and in the agility test. In conclusion, elite players showed greater performance in the RSA test, in the 30 m tests and in the agility test compared to amateur players. The contractile properties were not a key factor in the RSA performance of the futsal players. (shrink)

In futsal there are two referees on the playing court and their capacity to respond to physical and physiological demands imposed during the game is essential for the success. The futsal characteristics such as size pitch, referees position and rules of games or type of league could impose specific physical efforts probably. The aim of this study were to analyze the physical demands of eight elite referees from seven matches of Spanish Futsal Cup 2020. The physical activity of each referee (...) during the match was monitored with a Local Positioning System, which was installed on futsal pitch where the matches were played. The data differences were evaluated as Paired-Samples T-Test procedure. The results revealed a similar total distance between halves. The zone 3 distance showed a significative decrease during the match in comparison to the first and second halves. The number of high-intensity acceleration and deceleration decreased in the second half of the match. Therefore, the use of the tracking device to monitoring physical performance provides knowledge of the specific activity profile from futsal referees. This information to can be useful to design more accurate the training programs. (shrink)

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.

Automated Guided Vehicles (AGV) are an essential element of transport in industry 4.0. Although they may seem simple systems in terms of their kinematics, their dynamics is very complex, and it requires robust and efficient controllers for their routes in the workspaces. In this paper, we present the design and implementation of an intelligent controller of a hybrid AGV based on fuzzy logic. In addition, genetic algorithms have been used to optimize the speed control strategy, aiming at improving efficiency and (...) saving energy. The control architecture includes a fuzzy controller for trajectory tracking that has been enhanced with genetic algorithms. The cost function first maximizes the time in the circuit and then minimizes the guiding error. It has been validated on the mathematical model of a commercial hybrid AGV that merges tricycle and differential robot components. This model not only considers the kinematics and dynamics equations of the vehicle but also the impact of friction. The performance of the intelligent control strategy is compared with an optimized PID controller. Four paths were simulated to test the approach validity. (shrink)

La relevancia del pensamiento de Emmanuel Levinas para comprender el surgimiento de la filosofía de la liberación –uno de los movimientos filosóficos más importantes de América Latina durante la segunda mitad del siglo XX– es innegable. En este artículo se analiza la interpretación geopolítica y analógica que Enrique Dussel realizó de los conceptos levinasianos de “Alteridad” y “Otro” para mostrar su equivocidad en el ámbito de lo político.

Este artículo aborda la violencia como problema filosófico desde dos enfoques de pensamiento ubicados en latitudes geo-históricas distintas. En primer lugar, se presenta a la Escuela de Frankfurt, a través de la obra Dialéctica de la ilustración (1944/1947). En segundo lugar, desde América Latina se expone la Filosofía de la Liberación, a la luz de Enrique Dussel en los planteamientos de su obra El encubrimiento del otro: el origen del mito de la modernidad (1994). Ambos discursos articulan un análisis (...) crítico del fenómeno de la violencia, diagnosticando los síntomas degradados del proyecto civilizatorio de la Modernidad. (shrink)

The generation of the pitch control signal in a wind turbine (WT) is not straightforward due to the nonlinear dynamics of the system and the coupling of its internal variables; in addition, they are subjected to the uncertainty that comes from the random nature of the wind. Fuzzy logic has proved useful in applications with changing system parameters or where uncertainty is relevant as in this one, but the tuning of the fuzzy logic controller (FLC) parameters is neither straightforward nor (...) an easy task. On the other hand, reinforcement learning (RL) allows systems to automatically learn, and this capability can be exploited to tune the FLC. In this work, a WT pitch control architecture that uses RL to tune the membership functions and scale the output of a fuzzy controller is proposed. The RL strategy calculates the fuzzy controller gains in order to reduce the output power error of the WT according to the wind speed. Different reward mechanisms based on the output power error have been considered. Simulation results with different wind profiles show that this architecture performs better (123.7 W) in terms of power errors than an FLC without RL (133.2 W) or a simpler PID (208.8 W). Even more, it provides a smooth response and outperforms other hybrid controllers such as RL-PID and radial basis function neural network control. (shrink)

Psychological flexibility is a key concept of acceptation and commitment therapy. This factor has been linked with psychological wellbeing and associated factors, such as quality of life, in cancer patients. These and other positive results of acceptation and commitment therapy in cancer patients found in previous research could be enhanced by using mhealth tools. A three-arm randomized superiority clinical trial, with a pre-post-follow-up repeated measures intergroup design with a 1:1:1 allocation ratio is proposed. A hundred and twenty cancer patients will (...) be randomly assigned to one of the following interventions: face-to-face ACT + mobile application, face-to-face ACT, and Waitlist control group. The primary expected outcome is to observe significant improvements in psychological flexibility acceptance and action questionnaire- II in the face-to-face ACT + app group, after comparing baseline and post-treatment scores, and the scores will remain stable in the two assessment points, 3 and 6 months after the intervention. Secondary expected outcomes are significant increasing scores in quality of life and post-traumatic-growth, and significant decreasing scores in anxiety and depression, insomnia and fatigue at the same assessment points. Also, it is expected that the scores of this group will be higher than the scores of the face-to-face ACT group and the waitlist control group. This study aims to assess the efficacy of a combined intervention for psychological flexibility and associated symptoms in cancer patients. The results of this protocol may help to consider the use of acceptation and commitment therapy and mhealth applications in cancer settings as a valid therapeutic choice.Clinical Trial Registration[www.ClinicalTrials.gov], identifier [NCT05126823].

La filosofía judía contemporánea, particularmente la surgida de la historia herida del pensador lituano Emmanuel Levinas, presenta de modo exclusivista la reducción de la relación religiosa a relación ética. No sólo queda ahí su propuesta sino que este filó-sofo judío considera la experiencia mística una degeneración o peligro para la religiosidad auténtica. En cambio, el mayor especialista español en los estudios de fenomenología de la religión, el pensador cristiano Juan Martín Velasco, considera la experiencia mística como la culminación de la (...) experiencia religiosa.

Uno de los aspectos dominantes en los desarrollos de las ciencias sociales y las humanidades en la actualidad es la adaptación de enfoques naturalistas. Los programas naturalistas rechazan el estatuto de lo humano que había defendido tradicionalmente la filosofía al sostener que la conciencia es reducible a un hecho contingente y, por lo tanto, puede comprenderse desde un criterio meramente objetivista. El filósofo francés Jean-Marie Schaeffer llama a esta postura la “tesis de la excepción humana” y sostiene que la fenomenología (...) de Edmund Husserl es el último ejemplo de esta postura. Trataremos de mostrar que el antinaturalismo tan característico de la fenomenología husserliana es sostenible pese a la crítica de Schaeffer. En este sentido, buscamos explorar brevemente la posibilidad y sentido de una fenomenología naturalizada.One of the key aspects in the development of the social sciences and humanities today is the adaptation of naturalistic approaches. Naturalists programs reject the status of the human that had traditionally defended philosophy holding that consciousness is reducible to a contingent fact and, therefore, can be understood from a purely objectivist approach. The French philosopher Jean-Marie Schaeffer calls this approach the “thesis of human exception” and argues that the phenomenology of Edmund Husserl is the latest example of this approach. Try to show that the anti-naturalism so characteristic of Husserlian phenomenology is sustainable despite criticism of Schaeffer.

Resumen: En la primera parte del presente artículo se estudia la naturaleza de los denominados culturemas, entendidos como unidades semióticas cuyo referente es un elemento perteneciente a una cultura dada desconocido o sin equivalente exacto en otras culturas y que, por tanto, es percibida como una especificidad cultural. Igualmente, se analizan los criterios tanto para su clasificación tradicional por contenido referencial como su clasificación por relevancia semiótica en una traducción. En la segunda parte se aplica el método culturo-traductológico para analizar (...) culturemas presentes en la obra de Iván Turguéniev, Rudin, y la forma de transponerlos en las diferentes versiones al español existentes por parte de distintos traductores.: In the first part of this article, the nature of so-called culturemes is studied, understood as semiotic units referring to an element belonging to a given culture which is unknown or without an exact equivalent in other cultures, and which is therefore perceived as a cultural specificity. Additionally, criteria are examined for both their traditional classification by referential content, and their classification by semiotic relevance in a translation. In the second part, the cultural-traductological method is used to analyse culturemes present in Rudin, the work by Iván Turguéniev, and the way of transposing these in the different Spanish versions by different translators.

Does home-based family involvement influence academic performance? To answer this question, a case study research was carried out with 96 children from all six levels of primary education at a public school, and their families. Data regarding home-based family involvement were collected using a questionnaire. Academic achievement was measured from school marks. The results reveal that, apart from two of the factors considered, home–family involvement as a whole is not significantly related to academic achievement. These two factors are access to (...) informal education resources and parents’ employment. Family involvement related to the access of children to informal education resources is significantly related to a better academic achievement. Those students with both parents working perform best, and those with none working, worst. Although gender does not appear to significantly influence academic achievement and family involvement, the results show that girls attain better school performance and re... (shrink)

Firm managers play an important role in the implementation of corporate social responsibility (CSR) actions. Education is emerging as the key factor in developing a sense of moral responsibility amongst the business students who will eventually become company managers and decision makers. The aim of this research is, thus, twofold. First, to analyze the existence of a direct positive correlation between university students’ perception of CSR and its impact on business performance; and second, to examine the extent to which two (...) factors (advantages brought by CSR and responsibilities toward stakeholders) act as mediation variables in the aforementioned correlation. The analysis was performed with a sample of 390 business‐related university students. Amongst the potential contributions made by this study we can highlight the possibility of knowing future managers’ way of thinking and of knowing the aspects where educational centers might improve their CSR teaching.

We estimate the effect on business start-ups of a program that significantly speeds up firm registration procedures. The program was implemented in Mexico in different municipalities at different dates. Our estimates suggest that new start-ups increased by about 4% in eligible industries, and we present evidence that this is a causal effect. Most of the effect is temporary, concentrated in the first 10 months after implementation. The effect is robust to several specifications of the benchmark control group time trends. We (...) find that the program was more effective in municipalities with less corruption and cheaper additional procedures. (shrink)

This paper shows an analysis of some found solutions for the famous aporia of the race between Achilles and the Tortoise. As an introduction, we present the mechanical solution, to establish that it is not in the field of matters of fact where you can resolve a purely rational problem like the one raised by Zeno of Elea. And so, the main part of the article is dedicated to the mathematical solutions, which face the problem under the point of view (...) of the single, mathematical reason. There are two mathematical solutions for Zeno’s paradox. First, we attend to that which we denominate “classical” (because it is the most habitually used by mathematicians), which is based on the calculus of addiction of terms of a geometrical series in progressive decrease. The second considered solution is the one that was proposed by Russell, based upon the theory of the transfinite numbers. The analysis we have made gets us to discover that no one of those solutions can save itself from falling into logical contradictions, therefore it seems that Zeno’s problem is an authentic aporia, which, after so much time, continues challenging human intelligence. As the article’s conclusion, we suggest that the cause of the impossibility of solving Zeno’s problem is the very notion of mathematical continuum, because this notion infringes the logic of facts.

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)
