The Next Release Problem (NRP) is a combinatorial optimization problem that aims to find a subset of software requirements to be delivered in the next software release, which maximize the satisfaction of a list of clients and minimize the effort required by developers to implement them. Previous studies have applied various metaheuristics, mostly genetic algorithms. Estimation of Distribution Algorithms (EDA), based on probabilistic modelling, have been proved to obtain good results in problems where genetic algorithms struggle. In this paper we (...) propose to adapt three EDAs to tackle the multi-objective NRP in a fast and effective way. Results show that EDAs can be applicable to solve the NRP with rather good quality of solutions. Furthermore, we prove that their execution time can be significantly reduced using a per-iteration solution subset selection method while maintaining the overall quality of the solutions obtained, and they perform the best when limiting the search time as in an interactive tool that requires fast responsiveness. The experimental framework, code and datasets have been made public in a code repository. (shrink)

Background: This research explores how public awareness and attitudes toward donation and transplantation policies may contribute to Spain's success in cadaveric organ donation. Materials and Methods: A representative sample of 813 people residing in Andalusia (Southern Spain) were surveyed by telephone or via Internet between October and December 2018. Results: Most participants trust Spain's donation and transplantation system (93%) and wish to donate their organs after death (76%). Among donors, a majority have expressed their consent (59%), and few nondonors have (...) expressed their refusal (14%). Only a minority are aware of the presumed consent system in force (28%) and feel sufficiently informed regarding the requirements needed to be an organ donor (16%). Participants mainly consider that relatives should represent the deceased's preferences and be consulted when the deceased's wishes are unknown, as is the case in Spain. Conclusion: Public trust in the transplant system may contribute to Spain's high performance in organ donation. High levels of societal support toward organ donation and transplantation do not correspond with similar levels of public awareness of donation and transplantation policies in Spain. (shrink)

The expressivist account of knowledge attributions, while claiming that these attributions are nonfactual, also typically holds that they retain a factual component. This factual component involves the attribution of a belief. The aim of this work is to show that considerations analogous to those motivating an expressivist account of knowledge attributions can be applied to belief attributions. As a consequence, we claim that expressivists should not treat the so-called factual component as such. The phenomenon we focus on to claim that (...) belief attributions are non-factual is that of normative doxastic disagreement. We show through several examples that this kind of disagreement is analogous to that of the epistemic kind. The result will be a doxastic expressivism. Finally, we answer some objections that our doxastic expressivism could seem to face. (shrink)

In this paper, we address the question whether a mechanistic approach can account for evolutionary causes. The last decade has seen a major attempt to account for natural selection as a mechanism. Nevertheless, we stress the relevance of broadening the debate by including the other evolutionary causes inside the mechanistic approach, in order to be a legitimate conceptual framework on the same footing as other approaches to evolutionary theory. We analyse the current debate on natural selection as a mechanism, and (...) extend it to the rest of the evolutionary causes. We focus on three approaches that we call the stochastic view, the functional view, and the minimalist view. We argue that all of them are unable to account for evolutionary causes as mechanisms. It is concluded that the current mechanistic proposals cannot be accepted as a common framework for evolutionary causes. Finally, we outline some guidelines and requirements that any mechanistic proposal should meet in order to be applied to evolutionary theory. (shrink)

El lector me permitirá quizá que le explique de entrada el propósito y el alcance de este brevísimo ensayo, anticipándole los temas de las tres partes que lo componen. Primero, explico lo que quiero decir con la expresión «sociedad civil». Con este fin, describo un tipo o carácter ideal de sociedad civil, en torno al cual he organizado un esquema conceptual que utilizo desde hace años en un amplio programa de investigación en ciencia social; y esbozo las líneas de demarcación (...) entre mi uso de esa expresión y otros usos que se han hecho y se hacen tic ella. Segundo, reelaboro el proceso por el que comencé a utilizar este concepto a mediados de los años setenta. Se trata de un esbozo de reconstrucción, hipotético y fragmentario, del contexto de descubrimiento de aquel esquema conceptual. Es un flash back que me lleva de los primeros sesenta (podría haberme llevado más atrás) a mi libro Estado, burocracia y sociedad civil, que escribí en 1976 (Pérez- Díaz, 1978). Tercero, tomo nota de los cambios en mi posición a lo largo de estos años, y me interrogo sobre algunos de los problemas que me han llevado de la concepción de 1976 a la que expongo en La primacía de la sociedad civil de 1993 (Pérez- Díaz, 1993), y en mis trabajos ulteriores, donde hay un desplazamiento sistemático del énfasis de mi trabajo desde lo que Hamo (en la Primada) «sociedad civil sensu stricto» hacia la «sociedad civil sensu lato». La explicación podría radicar en la necesidad de revisar, ampliar y formalizar el esquema «acomodándolo»: uno, al proceso en curso de mis trabajos de investigación empírica, y a la importancia creciente en esos trabajos de los temas de autoridad pública, esfera pública y política pública; dos, al horizonte histórico del whithcring away del totalitarismo comunista; y tres, a mi interés creciente en los temas de tradición, instituciones y retórica. Aunque los tres factores están interrelacionados, centraré aquí mi atención sobre todo en el primero de ellos, es decir, en los estímulos para la re-elaboración del esquema originario que han procedido de mi experiencia de investigación empírica, con alguna referencia al segundo, dejando el tercero poco más que aludido.

Este artículo evalúa los alcances del Cuaderno Azul como crítica sistemática en contra de la que se ha denominado una concepción o explicación causal del significado, específicamente la que formula Russell en The Analysis of Mind. Tal evaluación procederá, primero, aclarando la manera como la concepción causal defiende una noción de significado entendida como la conducta adecuada según el acontecer de leyes causales de orden psicológico. En segundo lugar, desarrollando la crítica que Wittgenstein elabora en el Cuaderno Azul contra la (...) concepción russelliana en tres momentos: 1) la crítica a la hipótesis de las imágenes; 2) el rechazo a la existencia de un proceso interno y oculto; 3) el abandono de una noción psicológica de comprensión para explicar el concepto de significado. Finalmente se aclarará de qué manera toda la crítica del Cuaderno Azul está orientada a debilitar la pretensión que subyace a la explicación causal de explicar científicamente el concepto de significado.

El artículo desarrolla el estado de la cuestión respecto a los elementos de la práctica deportiva que influyen en la producción de emociones. Se focaliza la selección bibliográfica desde la perspectiva teórica y metodológica procedente de la sociología y la psicología social. En las conclusiones se muestra que la frecuencia de la práctica deportiva, el grado de interacción y la presencia de competición son los principales factores que influyen en la producción emocional.

My purpose in this article is to provide a reconstruction of the mechanics of philosophical analysis that Wittgenstein carried out in “On Certainty”. I will show that this analysis is based, specifically, on an appeal to a wide propositional typology that serves to evaluate and diagnose Moore’s propositions. To this end, I shall first explain how common readings of the methodological issues in “On Certainty” fail. Secondly, I focus on the mechanics of analysis found in paragraphs 1-65, specifically the analysis (...) of three sentences: “There are physical objects”, “I know that there is a hand here” and “here the mistake is impossible”. Thirdly, I proceed to identify different stages of the method and justify in what sense the strategic core of such research is the table of propositional typologies. (shrink)

La experiencia hermenéutica, para Gadamer, posee tres momentos fundamentales en los que se reúnen el componente empírico, histórico y el lingüístico. El objetivo general de este escrito es ver cómo se da este fenómeno en el caso de la experiencia estética. Para ello, en una primera parte, desarrollaremos el modelo del encuentro con otro que se comporta como un tú, es decir, que interpela e interroga, con lo que expondremos un aspecto esencial del carácter lingüístico de toda experiencia. En una (...) segunda parte nos preguntaremos si este modelo del ‘tú’ es extensible a la experiencia estética. En función de esto veremos los llamados tres momentos de la experiencia según Gadamer en el modo en que se dan tanto en el caso del encuentro con otro, que se comporta como un tú, y en el caso de la experiencia estética; destacando tangencialmente, en ambos casos, las vertientes kantianas de la exposición de Gadamer. Understanding and beauty: parallels between hermeneutic and aesthetic experience, according to Hans-Georg Gadamer According to Hans-Georg Gadamer the hermeneutical experience has three fundamental moments in which the empirical, historical and linguistic components meet. The overall objective of this paper is to see how this phenomenon occurs in the case of aesthetic experience. For this purpose, in the first part we will develop the model wherein one experiences an encounter with another who behaves like oneself, that is to say, who challenges and questions. This will expose an essential aspect of all linguistic experience. In the second part, we will inquiry if this model of the other being “you” can be extended to the aesthetic experience. On this basis we see the so-called three moments of the experience according to Gadamer, in the way they are displayed both for the encounter with another who behaves as a “ you” , and in the case of the aesthetic experience. For both cases, we will tangentially highlight the Kantian aspects of Gadamer’s explanation. (shrink)

El propósito de este texto es aclarar la dirección, los alcances y los límites del análisis filosófico según lo concibe Peter Strawson en Análisis y metafísica. Para el autor el análisis filosófico asume la forma de una metafísica descriptiva, esto es, de una teoría que exhibe cuáles son, y cómo se relacionan, los distintos elementos que componen nuestro esquema conceptual ordinario. Para lograr tal teoría descriptiva se debe adoptar un estilo de análisis que el autor denomina conectivo, cuya meta es (...) identificar cuáles conceptos, al interior de nuestro esquema son básicos o fundamentales. A este fin deberán aplicarse tres criterios: generalidad, irreductibilidad y no contingencia. (shrink)

We prove that WRP and saturation of the ideal NSω1together imply$\left\{ {a \in [\lambda ]^{\omega _1 } :{\text{cof}}\left( {{\text{sup}}\left( a \right)} \right) = \omega _1 } \right\}$, for every cardinalλwith cof(λ)≥ω2.

We show that both Rado's Conjecture and strong Chang's Conjecture imply that there are no special ℵ2-Aronszajn trees if the Continuum Hypothesis fails. We give similar result for trees of higher heights and we also investigate the influence of Rado's Conjecture on square sequences.

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

We consider several game versions of the cardinal invariants \, \ and \. We show that the standard proof that parametrized diamond principles prove that the cardinal invariants are small actually shows that their game counterparts are small. On the other hand we show that \ and \ are both relatively consistent with ZFC, where \ and \ are the principal game versions of \ and \, respectively. The corresponding question for \ remains open.

For years theists have claimed that the constants of physics had to be finely tuned by God to the values that have for life in the universe to be possible. In my column of June, 2009 I showed that many of these claims are based on an improper analysis of the data. Even some of the competent scientists who write on this subject commit the fallacy of holding all the parameters constant and varying just one. When you allow all to (...) vary, you find that changes to one parameter can be easily compensated for by changes to another, leaving the ingredients for life in place. This point is also made nicely in a recent Scientific American cover story by Alejandro Jenkins and Gilad Perez. In this column I will discuss perhaps the most cited example of claimed fine-tuning, the Hoyle resonance. In 1953 the famous astronomer Fred Hoyle calculated that the production of carbon would not occur with sufficient probability unless that probability was boosted by the presence of an excited nuclear state of C12 at a very specific energy. In what appeared to be a remarkable victory for anthropic reasoning, Hoyle proposed that this previously unknown state must exist at about 7.7 MeV. (shrink)

The aim of this paper is to use the approaches of the Korean philosopher Byung-Chul Han, on the one hand, to show the challenges that formulate and define our times and, on the other, to focus this view on education. In this sense, it is necessary to define the post-pandemic 21st century society marked by psychopolitics. Education is subject to a framework of unprecedented complexity, due to digitalisation and the acceleration of a world that is perceived as progressing, and yet (...) is becoming increasingly ill due to an excess of positivity. The pedagogy that operates through pleasure and the new relational plane of social networks, which formulate affine and disembodied encounters, eliminates negativity. Education lends itself to a demanding examination as the starting point of this society and is seen as the place where the possibility of transformation arises. In the latter sense it is argued that philosophy in our classrooms has a crucial role to play. (shrink)

Emotional disorder symptoms are highly prevalent and a common cause of disability among children and adolescents. Screening and early detection are needed to identify those who need help and to improve treatment outcomes. Nowadays, especially with the arrival of the COVID-19 outbreak, assessment is increasingly conducted online, resulting in the need for brief online screening measures. The aim of the current study was to examine the reliability and different sources of validity evidence of a new web-based screening questionnaire for emotional (...) disorder symptoms, the DetectaWeb-Distress Scale, which assesses mood, anxiety, obsessive–compulsive disorder, post-traumatic stress disorder, suicidality, and global distress. A total of 1,499 participants completed the DetectaWeb-Distress Scale and specific questionnaires for emotional disorder symptoms, suicidal behaviors, and well-being through a web-based survey. Results indicated that a structural model of 10 correlated factors fits reasonably better in comparison to the remaining models; measurement invariance for age and gender; good internal consistency ; and significant positive correlation with other measures of anxiety, depression, PTSD, or distress, and negative correlation with well-being measures, displaying support for convergent-discriminant validity. We also found that girls scored higher than boys on most of the subscales, and children had higher scores for social anxiety, specific phobia, panic disorder, and obsessive–compulsive symptoms, whereas adolescents scored higher on depressive symptoms, suicidality, and generalized anxiety, but the effect sizes were small to medium for all comparisons. The DetectaWeb-Distress Scale is a valid, innovative, and useful online tool for the screening and evaluation of preventive programs for mental health in children and adolescents. (shrink)

Además, pondremos (...) de relieve las principales estadísticas en torno al uso de los ERTE en los últimos años. (shrink)

El capitalismo histórico ha experimentado, en la escala mundial que hoy le corresponde, profundos cambios que han modificado sustancialmente su componente de acumulación, pero también, de forma significativa, el de regulación, perturbando críticamente su forma de gestionar las inequidades, desigualdades y doxas que él mismo produce. Actualmente, la expansión de un capitalismo autoritario premunido del paradigma mercantil, promueve una cultura individual que ha calado duramente en los sujetos ..

El punto central del artículo lo constituyen las diferencias entre el análisis marxista clásico o “sistémico” y sus nuevas vertientes “abiertas” o “autonomistas”. Se crítican ciertos discursos testimoniales y rebeldes de la resistencia anticapitalista (John Holloway), las que no darían cuenta del legado teórico de las modalidades clásicas del antagonismo Capital/Trabajo, surgidas de la experiencia sociohistórica de las luchas sociales. Por el contrario, el texto aboga por un análisis más profundo de la nueva fase del capitalismo mundializado y por el (...) rescate de formas organizativas de resistencia que den cuenta del nuevo contexto global.

Obesity is characterized by the accumulation of an excessive amount of fat mass in the adipose tissue, subcutaneous, or inside certain organs. The risk does not lie so much in the amount of fat accumulated as in its distribution. Abdominal obesity is an important risk factor for cardiovascular diseases, diabetes, and cancer, having an important role in the so-called metabolic syndrome. Therefore, it is necessary to prevent, detect, and appropriately treat obesity. The diagnosis is based on anthropometric indices that have (...) been associated with adiposity and its distribution. Indices themselves, or a combination of some of them, conform to a big picture with different values to establish risk. Anthropometric indices can be used for risk identification, intervention, or impact evaluation on nutritional status or health; therefore, they will be called anthropometric health indicators. We have found 17 AHIs that can be obtained or estimated from 3D human shapes, being a noninvasive alternative compared to X-ray-based systems, and more accessible than high-cost equipment. A literature review has been conducted to analyze the following information for each indicator: definition; main calculation or obtaining methods used; health aspects associated with the indicator ; criteria to classify the population by means of percentiles or cutoff points, and based on variables such as sex, age, ethnicity, or geographic area, and limitations.
