Localization Wireless Sensor Networks (WSN) represent a research topic with increasing interest due to their numerous applications. However, the viability of these systems is compromised by the attained localization uncertainties once implemented, since the network performance is highly dependent on the sensors location. The Node Location Problem (NLP) aims to obtain the optimal distribution of sensors for a particular environment, a problem already categorized as NP-Hard. Furthermore, localization WSN usually perform a sensor selection for determining which nodes are to be (...) utilized for maximizing the achieved accuracy. This problem, defined as the Sensor Selection Problem (SSP), has also been categorized as NP-Hard. While different metaheuristics have been proposed for attaining a near optimal solution in both problems, no approach has considered the two problems simultaneously, thus resulting in suboptimal solutions since the SSP is biased by the actual node distribution once deployed. In this paper, a combined approach of both problems simultaneously is proposed, thus considering the SSP within the NLP. Furthermore, a novel metaheuristic combining the Black Widow Optimization (BWO) algorithm and the Variable Neighbourhood Descent Chains (VND-Chains) local search, denominated as BWO-VND-Chains, is particularly devised for the first time in the author’s best knowledge for the NLP, resulting in a more efficient and robust optimization technique. Finally, a comparison of different metaheuristic algorithms is proposed over an actual urban scenario, considering different sensor selection criteria in order to attain the best methodology and selection technique. Results show that the newly devised algorithm with the SSP criteria optimization achieves mean localization uncertainties up to 19.66 % lower than traditional methodologies. (shrink)

Desde la perspectiva de la «sociología del espacio» el estudio explora las conexiones que se dan entre los factores ideológicos (paradigmas de representación del parto), los siste­mas de organización clínica (culturas del parto) y las evoluciones arquitectónicas (tipologías espaciales de los paritorios), y sus re­percusiones en clave de humanización asistencial. Para ello se ha realizado una investigación etnográfica de veinticuatro meses de duración en seis paritorios del servicio estatal de salud de una re­gión del sur de España. La técnica de (...) investigación fue la observa­ción participante, acumulando un total de trescientas veinticuatro horas de análisis. Los resultados muestran cómo las disposiciones arquitectónicas están íntimamente ligadas a los paradigmas y cul­turas obstétricas preexistentes, tendiendo desde las perspectivas tecnocráticas, en clave orgánica, a una fragmentación del espacio asistencial que deshumaniza el proceso, y desde las cosmovisio­nes holístico-humanísticas, en clave de continuum, a una reinte­gración espacio-asistencial que contribuye a la humanización.

Este trabajo tiene como objetivo caracterizar el proceso de evaluación del aprendizaje del contenido estadístico en la carrera de Medicina. Los resultados obtenidos evidencian que el nivel de asimilación alcanzado por los estudiantes en muchas ocasiones es el reproductivo, lo que refleja la necesidad de seguir profundizando en los estudios de esta problemática. Issues related to the learning evaluation have been present throughout the teaching learning process history. The following research aims at characterizing the learning process of evaluation of the (...) statistical content in medicine. Results demonstrate that the assimilation level reached by students, on many occasions, is the reproductive one, as a need to deepen on methodology of the design of the system of evaluation of the statistical content learning in medicine.

El presente artículo busca proponer un acercamiento a la influencia del pensamiento de Thomas Hobbes y su obra en el pensamiento económico. En especial en las escuelas marxista, neoclásica y keynesiana. El influjo de su pensamiento puede evidenciarse en el abordaje metodológico, antropológico e institucional. Se ofrece una Mirada sobre la sociedad civil (comercial), el Mercado y el Estado al mismo tiempo. Hobbes ha sido la inspiración de un concepto de Estado monolítico en lo político, en este sentido, la mirada (...) de la economía bajo el concepto de un gran planificador centralizado, tiene importantes antecedentes en este autor. El ejercicio del control social del individuo como propuesta institucional, en varias escuelas de la economía comparten con Hobbes, varios antecedentes que merecen ser analizados. (shrink)

The relationship between ethics and performance has previously been addressed in the literature, although there are still some gaps, for example, the relationship of ethical ideologies to student performance. This work aims to contribute to the literature with a statistical evaluation using partial least squares path modelling (PLS-PM) regarding whether university students’ ethical ideologies and moral meaningfulness influence their level of student performance and academic achievement. Results indicate that the ideologies of justice and deontology increase moral meaningfulness, moral meaningfulness in (...) turn increase student’s citizenship behaviours and student’s in-role performance, and finally, student’s in-role performance positively influences academic achievement. This research provides resources applicable to the fields of pedagogy and ethics to encourage performance during the study and highlight the value of the ideologies of justice and deontology.

This study tested a structural model of cognitive-emotional explanatory variables to explain performance in mathematics. The predictor variables assessed were related to students’ level of development of early mathematical competencies (EMCs), specifically, relational and numerical competencies, predisposition toward mathematics, and the level of logical intelligence in a population of primary school Chilean students (n = 634). This longitudinal study also included the academic performance of the students during a period of four years as a variable. The sampled students were initially (...) assessed by means of an Early Numeracy Test (ENT), and, subsequently, they were administered a Likert-type scale to measure their predisposition toward mathematics (EPMAT) and a basic test of logical intelligence (TILE). The results of these tests were used to analyse the interaction of all the aforementioned variables by means of a structural equations model. This combined interaction model was able to predict 64.3% of the variability of observed performance. Preschool students' performance in EMCs was a strong predictor for achievement in mathematics for students between 8 to 11 years of age. Therefore, this paper highlights the importance of EMCs and the modulating role of predisposition toward mathematics. Also, this paper discusses the educational role of these findings, as well as possible ways to improve negative predispositions toward mathematical tasks in the school domain. (shrink)

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

This paper examines the various theories of intergenerational justice and its implications in the practical context of pension systems. In this context the sustainability of the system appears to be compromised by demographic projections. This fact has an unquestionable relevance for the future of this very important public service and the intergenerational commitment that this implies. In this sense if a pension system wants to be fair it has to look in three directions: pensioners, workers and future generations. So, a (...) liberal-egalitarian theory becomes necessary to share the risks of demographic and financial shocks between different generations and to reduce inequality as much as possible. (shrink)

Based on published works and unpublished materials, this article analyses how cybernetics was received by two Spanish thinkers exiled in Mexico: José Gaos (1900–1969) and Eduardo Nicol (1907–1990). This reception is particularly intriguing especially when considering the substantial presence and social impact that Norbert Wiener had in Mexican society because of his friendship with Arturo Rosenblueth. Gaos and Nicol are the first philosophers to develop a complex and original diagnosis of cybernetics in Mexico. It will be shown how the (...) exiled thinkers take on the philosophical implications of this science in the light of their respective theoretical projects, and finally, it will be defended how the critical perspective they develop is particularly significant for Mexico’s political and academic context since it illuminates some negative aspects of cybernetics that Wiener did not foresee and that had not been reported there until then.

Jeffrey King has famously argued that there are several prima facie problems with the direct reference theory of the semantics of complex demonstratives, three of which apparently resist solution. King concludes by observing that, if these outstanding problems cannot be solved, then the prospects for a direct reference semantics for complex demonstratives will be poor. I shall focus on just one of these outstanding problems—the objection from belief attributions—and suggest that it, at least, can be answered.

En el presente trabajo se realizará un análisis y comparación críticos de las ideas con relación a la tecnología desarrolladas por Eduardo Nicol y Adolfo Sánchez Vázquez. En ese sentido, se confrontará el concepto de “razón de fuerza mayor” de Nicol con la idea del “racionalismo tecnológico” de Sánchez Vázquez. Demostrando, finalmente, que el concepto nicoliano encajaría perfectamente dentro de los parámetros de la ideología del racionalismo tecnológico tal y como la define Adolfo Sánchez Vázquez. Todo ello con el fin (...) de valorar el alcance y las limitaciones de las propuestas de ambos autores y su posible vigencia de cara a pensar un problema tan actual como el de la tecnología y la responsabilidad del ser humano en su desarrollo. Así pues, este trabajo no se propone estudiar un diálogo o polémica real entre los autores en cuestión ni tampoco se hace cargo de una crítica explícita de uno a otro. Lo que se busca es conectar dos desarrollos filosóficos aparentemente alejados (la metafísica fenomenológica de Nicol y el marxismo crítico de Sánchez Vázquez) examinando cómo abordan uno y otro el tema de la tecnología y destacando las hipotéticas implicaciones de uno de esos desarrollos sobre el otro. Para ello, se parte de una breve explicación del contexto histórico de ambos pensadores, luego se enmarcan las ideas de la tecnología de cada uno en su contrastante concepción de la praxis, se muestran los puntos en común y las discrepancias y, finalmente, se termina señalando la hipotética repercusión de las ideas Sánchez Vázquez sobre las de Nicol.

El presente artículo se confronta con una problemática que ha focalizado los debates teóricos en torno a los fundamentos normativos de la crítica en las últimas décadas. La cuestión es si, en un marco social escindido como el nuestro, la crítica tiene que asumir su carácter perspectivista, es decir, su estar ubicada en una de las perspectivas que se enfrentan en el escenario social. Si ello es así, el problema que se abre es el de la posibilidad o no de (...) legitimar racional, moral y políticamente una crítica que asume su estar ya siempre situada en uno de los horizontes normativos que coexisten en el marco social. Este trabajo afronta este problema poniendo en diálogo motivos de la hermenéutica y de la teoría crítica: con ello pretende realizar una aportación a lo que podríamos llamar una reflexión hermenéutica de la crítica, que logre articular carácter perspectivo y pretensión de normatividad de la misma.

Este trabajo consiste en una aproximación a las razones de la democracia y al papel de la opinión pública en la misma. Contiene también un ensayo conceptual analítico que pretende dar cuenta suficientemente de los elementos definitorios de esos dos conceptos centrales del discurso político y jurídico. Democracia y opinión pública no son realidades identificables de manera indiscutible y no siempre cuando se habla de ellas se hace un uso homogéneo de los términos y de su sentido político. Este trabajo (...) pretende dar respuesta, aunque sea con carácter no definitivo, a algunos de los interrogantes que derivan de las distintas propuestas sobre la democracia y sobre la opinión pública que se han ofrecido por el pensamiento político moderno y contemporáneo.

A distinção entre interior e exterior é um tema recorrente na história da filosofia. Embora a maioria das vezes seja assumido de forma implícita nas reflexões filosóficas, é fundamental procurar esclarecê-lo. Desde a noção socrática de interior como aquilo que importa realmente conhecer, passando pela conceção agostiniana de marca da transcendência até às perspetivas de Fernando Pessoa e Wittgenstein, percorre-se um caminho merecedor da nossa atenção.

The influence of Saint Augustine in the existential analysis of Being and Time is highly recognized and is always a source of fruitful research. Our work, however, will try to discover the elongated shadow of the bishop of Hippo in the definition of the task of thinking, and therefore in II Heidegger, from what we will call the salvation of the vital-existential moment of the experience of the encounter with the absolute. It is investigated here, then, the possibility that the (...) fundamental notes on which, in our opinion, the mystical experience that is inferred in the Confessions can count as formal indicators of what is the heideggerian notion of meditative thinking.

El cosmopolitismo es uno de los elementos fundamentales de la concepción de la justicia defendida por M.C. Nussbaum. Esta sería una de las tesis esenciales del presente ensayo. El enfoque de las capacidades (EC) defendido por ella pretende ser una alternativa a las modernas teorías del contrato. Para Nussbaum, dignidad, capacidades humanas y recursos materiales son indesligables. Del mismo modo, la perspectiva cosmopolita es una exigencia inexcusable en la teoría de la justicia de Nussbaum. En este artículo tratamos de rastrear (...) los distintos ingredientes de esta, sus raíces en el cosmopolitismo estoico, y también su discusión con él para afrontar los desafíos que plantea la justicia global en el presente, con una perspectiva de futuro.

O texto pretende dar-nos conta da evolução do liberalismo em Portugal centrando-se no confronto histórico entre duas concepções de ordenação da sociedade. Um confronto entre dois modelos-tipo de liberalismo – “francês” ou racionalista e “inglês” ou clássico – que, embora atravesse a história europeia, teve particular eco em Portugal.É a partir deste contraste, antecipado por Alexandre Herculano, que se procura compreender o por quê de durante quase dois séculos o nosso liberalismo ter sido vítima fácil da luta entre dois pólos (...) autoritários e centralistas, dado que quase todos – apesar das diferenças entre reaccionários e progressistas, conservadores e socialistas – concordavam no uso do poder do Estado como determinante principal das suas políticas. Trata-se, afinal, de uma outra forma de nos interrogarmos sobre se terá havido “pensamento liberal” ou mesmo “revolução liberal” em Portugal. (shrink)

RESUMEN Frente a la hybris de la subjetividad que culmina en el proyecto moderno-humanista, surge la necesidad de pensar de otra manera la esencia del hombre ya sin el lastre de toda la tradición filosófica occidental. Este viraje que Heidegger imprime al pensar se explica aquí desde lo que denomino tesis para la reconstrucción de un posthumanismo en la perspectiva de la kénosis y que se resume en: la superación de las leyes de la gramática y el acento en el (...) decir poético; el reconocimiento del mientras tanto de la existencia humana finita siempre en camino; y, por último, el preciso abajamiento del pensar tal y como corresponde no ya a la incontestable potestad del señor del ente sino a la esencial pobreza del pastor. ABSTRACT Before the hybris of subjectivity that culminates in the modern-humanist project, there arises the need to think the essence of man, in another way, a way already without the burden of the entire western philosophical tradition. This turn that Heidegger gives to thinking is here explained from what I call: thesis for the reconstruction of post-humanism in the perspective of kenosis, which can be summarized as overcoming the laws of grammar and accent in the poetic saying, recognition of a meanwhile of the finite human existence always on its way and, finally, the precise reduction of thinking as it corresponds not to the power of the lord of the being but to the essential shepherd’s poverty.
