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.

It is widely held that there is a distinctive norm of assertion. A plausible idea is that there is an analogous, perhaps weaker, norm for indirect communication via implicatures. I argue against this type of proposal. My claim is that the norm of assertion is a social norm governing public updates to the conversational record. Off the record implicatures are not subject to social norms of this type. I grant that, as happens in general with intentional actions, off the record communicative acts may be subject to normative assessments on different levels (for instance, regarding their moral or prudential appropriateness). However, such assessments do not generate distinctive norms that apply to all cases of implicature.

Advances in technology, research development, and teaching practices have brought improvements in the training, levels of autonomy, and quality of life of people who need support and resources appropriate to their circumstances of disability. This article focuses on empirically analyzing the usefulness of treatments that have been supported by technology to answer the question “How do technological ecosystems being used help people with special educational needs?” The multiple case study methodology was used to address six categories of analysis: project data, objectives, processes, outputs and outcomes, technologies, and impact. The processes, open in communication, were characterized as transversal, ethical, and sustainable. The results yielded various technological ecosystems that support people with disabilities, deliver the help they need to improve their health, and provide enjoyable user experiences. At the same time, they promote the training and improvement of teaching methodologies and involve families in order to improve their knowledge, attitudes, and care of children, young people, and adults with functional diversity.

En los últimos 20 años el debate entre los Factores Comunes y los Tratamientos con Apoyo Empírico (TAE) ha sido uno de los más relevantes para la práctica clínica. El enfoque TAE con origen en la investigación sobre fármacos (Medicina Basada en la Evidencia), promueve el uso de técnicas específicas y protocolos de tratamiento. Los Factores Comunes, por el contrario, señalan la validez de múltiples psicoterapias, la cual estaría basada en dimensiones comunes a todo tratamiento, y no tanto en el uso de técnicas específicas. El proceder médico y farmacológico encaja razonablemente dentro de un marco de acción instrumental, en el que el acto sanitario se ejerce a fin de modificar ciertos parámetros fisiológico-anatómicos. Pero la psicoterapia es mejor entendida como una relación entre sujetos, ya que el paciente, el objeto de la acción terapéutica, es también un sujeto, y no un parámetro. Por ello los protocolos como secuencias prefijadas de acciones del terapeuta (ideal para la investigación por su replicabilidad y pertinencia metodológica), implican una suerte de eliminación del sujeto. Cabe entonces entender el sentido de los protocolos de tratamiento como marcos de sentido, de problemas pertinentes, de soluciones indicadas. Como una forma de conocimiento flexible sobre el problema y su funcionamiento y manejo.

ABSTRACT Anti-normativists have advanced the view that the involvement of content in norms is not an essential feature of content, but a contingent feature or side effect of the normativity governing attitudes. In this paper, we argue that, in its original formulation, this view puts too much weight on the idea that belief is the fundamental, and perhaps the only, source of content-involving normativity. In its more refined formulation, however, the view does not make justice to a neutral and encompassing characterization of what it is for content to be essentially normative.

Background: Limited evidence exists comprehensively assessing physical fitness attributes, physical activity behaviors, nutritional habits, and nutritional knowledge according to sex in basketball players during early adolescence. Insight of this nature could be used to optimize the training process and lifestyles in young basketball players.Objective: To compare physical fitness attributes, physical activity levels, nutritional habits, and nutritional knowledge between elite male and female basketball players under 14 years of age.Methods: Twenty-three U-14 basketball players from the same elite basketball academy participated in this study. Physical fitness attributes were assessed using a basketball-specific test battery, while physical activity levels, nutritional habits, and nutritional knowledge were assessed using questionnaires.Results: Male players exhibited better physical fitness in all tests. Of note, a high proportion of players declared never or only sometimes eating fruit and vegetables. In addition, relatively poor nutritional knowledge was evident in all players with the group correctly answering <50% of nutritional questions overall and according to sex.Conclusion: These findings emphasize the necessity to perform individualized prescription of training stimuli across sexes to optimize the physical preparedness and development of youth basketball players. Additionally, strategies such as nutrition-focused education interventions may be necessary in this population given the low consumption of fruits and vegetables, as well as the poor nutritional knowledge observed in players.

El presente escrito tiene la motivación de arrojar algo de luz sobre una dificultad intrínseca a la función social que cumple el Derecho: el manejo de la diversidad. En particular, la diversidad psicosocial ha supuesto históricamente un obstáculo persistente a la configuración de un molde jurídico que permita incluir en él todo el espectro de la realidad. El argumento que vehicula la exposición es que el carácter irresoluble de esta tensión conduce a la criminalización de una subjetividad que escapa a la pulsión normalizadora del sistema. Abordando las diferentes coyunturas que tratan, sin éxito, de disolver todas las diferencias en su seno se intentará demostrar la incompatibilidad de este proceso con la realización plena de los individuos.

Platón y Kant plantean un modelo “constitucional” del alma, en el que la razón y el apetito o la pasión tienen diferentes roles estructurales y funcionales en la generación de la motivación, en contraposición al común “modelo combativo,” en el que son mostrados como fuentes de motivación independientes que luchan por el control. Desde el punto de vista del modelo constitucional, podemos explicar qué hace que una acción sea diferente de un evento. Lo que hace que una acción sea atribuible a una persona y, por lo tanto, lo que la hace una acción, es que surge desde la constitución de la persona y, por lo tanto, desde la persona como un todo, y no desde una fuerza que actúa sobre o en ella. Esto, a su vez, implica una explicación de lo que hace buena a una acción: lo que hace que una acción sea buena es que se delibere sobre ella y se la elija de una manera que unifique a la persona en un sistema constitucional. A través de la acción deliberativa nos constituimos como agentes unificados. La justicia platónica y el imperativo categórico de Kant se muestran como estándares normativos para la acción porque son principios de autoconstitución.

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.

Prenatal genetic diagnosis with new high-performance technologies such as genomic array adds great complexity to the ethical dilemmas that already exist in current medicine. The main objective of this study was to carry out an analysis and bioethical reflections centred on the outcome associated with the use of the genetic array technique in 185 pregnancies at the Hospital Universitario y Politécnico La Fe (Valencia, Spain). It is an observational, descriptive and cross-sectional study during the years 2014 to 2017, inclusive. We analyse the results and the follow-up of the 185 cases in which this prenatal genetic study was carried out by array technique. Of the 185 prenatal genetic studies carried out, 165 showed no copy number variants (normal result) and in the 20 remaining pregnancies (10.81%), a dose change was detected. Abortion was carried out in 11 cases with pathological and/or probably pathological abnormalities. Of the 165 cases in which no dose variant was detected, an abortion was carried out in 49 cases, which represents 29.7%. The introduction of new genomic analysis techniques to invasive prenatal diagnosis highlights the ethical problems that arise above all in the interpretation of genetic variants detected and genetic counselling, while emphasising the need for correct informed consent and it adds, if possible, more controversy to a subject with great bioethical substance such as abortion.

Daniel Whiting has argued, in this journal, that Mark Schroeder’s analysis of knowledge in terms of subjectively and objectively sufficient reasons for belief makes wrong predictions in fake barn cases. Schroeder has replied that this problem may be avoided if one adopts a suitable account of perceptual reasons. I argue that Schroeder’s reply fails to deal with the general worry underlying Whiting’s purported counterexample, because one can construct analogous potential counterexamples that do not involve perceptual reasons at all. Nevertheless, I claim that it is possible to overcome Whiting’s objection, by showing that it rests on an inadequate characterization of how defeat works in the examples in question.

In this paper I argue that defeasible inferences are occasion-sensitive: the inferential connections of a given claim depend on features of the circumstances surrounding the occasion of inference. More specifically, it is an occasion-sensitive matter which possible defeaters have to be considered explicitly by the premises of an inference and which possible defeaters may remain unconsidered, without making the inference enthymematic. As a result, a largely unexplored form of occasion-sensitivity arises in inferentialist theories of content that appeal to defeasible inferences.

Los cimientos de una sociedad racional en Horkheimer parten de la premisa de hacer de la filosofía social una opción por la Teoría Crítica. Por ello [1] se desarrolla una interpretación dialéctica de lo social entre la filosofía y las teorías de las ciencias sociales, desde la categoría del materialismo interdisciplinario. [2] Caracterizar una época en estado de indigencia inicia definiendo la Ilustración como un proceso de desencantamiento del mundo que reduce la realidad humana en el signo del dominio . El curso liberador de la Ilustración fue viciado desde el principio y terminó siendo un proceso de alienación y de cosificación. [3] Por tanto, se ponen en escena los sentimientos morales de la compasión y la solidaridad política para abordar una nueva perspectiva ética que define un imperativo existencial capaz de ver la miseria humana y la búsqueda de la felicidad, con el propósito de superar las condiciones y realidades de esta época en estado de indigencia
