ObjectiveThis study aimed to analyze the influence and measurement of the relationship and interaction between the elderly lifestyles after the appearance of the SARS-CoV-2 variant and the factors analyzed comprised life satisfaction levels, social relationships, and daily-life activities.MethodsThe study population was ≥ 65 in Castile-La Mancha. The research design was quantitative and arose from primary data collected via an ad hoc survey carried out through the Computer Assisted Telephone Interview system by randomly stratified sampling. The sample size was made up (...) of 1,065 cases, and the participants were selected through a random sampling stratified by gender quotas, age, province, and habitat size.ResultsThe results obtained revealed two main lifestyles, from which a notable behavioral change in personal relationships led to infer toward alternative lifestyles.ConclusionNotwithstanding the variation in lifestyles of the elderly after the pandemic, certain relationships remained unaltered. Thus, from the analyzed variables, relatives and friends relationships were scarcely influenced by the supervened incident. (shrink)

Adaptive optics are techniques used for processing the spatial resolution of astronomical images taken from large ground-based telescopes. In this work, computational results are presented for a modified curvature sensor, the tomographic pupil image wavefront sensor, which measures the turbulence of the atmosphere, expressed in terms of an expansion over Zernike polynomials. Convolutional neural networks are presented as an alternative to the TPI-WFS reconstruction. This technique is a machine learning model of the family of artificial neural networks, which are widely (...) known for its performance as modeling and prediction technique in complex systems. Results obtained from the reconstruction of the networks are compared with the TPI-WFS reconstruction by estimating errors and optical measurements. The reconstructed wavefronts from both techniques are compared for wavefronts of 153 Zernike modes. For this case, a detailed comparison and grid search to find the most suitable neural network is performed, searching between multi-layer perceptron, CNN and recurrent networks topologies. In general, the best network was a CNN trained for TPI-WFS reconstruction, achieving better performance than the reconstruction software from TPI-WFS in most of the turbulent profiles, but the most significant improvements were found for higher turbulent profiles that have the lowest r0 values.

This article studies the observations which John Stuart Mill collected about Spain in his writings. The aim is to analyze how one of the most important thinkers of the time valued some political Spanish events, certain aspects of socioeconomic reality, or determined features which he considered to constitute the Spanish «national character». Throughout his entire intellectual trajectory, Mill seems to have been aware of the complex and eventful life of Spanish politics. Moreover, Mill visited Spain in 1860 and captured the (...) image of a country in a process of economic transformation, similar to the image portrayed by historians today and far from the romantic stereotypes that were so common to travel books of the 19th century.

This paper proposes and analyzes the psychometric properties of the PREVI-A scale. It describes the process of item development, the factorial structure of the scale, reliability, evidence of validity and diagnostic performance with regard to recidivism risk in juvenile offenders. The sample was made up of 212 juvenile offenders held at detention centers run by the Madrid Agency for Reeducation and Reintegration of Juvenile Offenders, a regional government body. Statistical analyses were used to corroborate the theoretical factorial structure of the (...) PREVI-A, which consists of six risk/protection dimensions based on the Risk-Needs-Responsivity Model, and to obtain empirical support for the reliability and validity of PREVI-A as a tool to assess the risk of recidivism by juvenile offenders in Spain.

This article analyzes Toole’s novel from a causal perspective, focusing on the cause-effect dynamics that make the plot advance, from the initial event at D.H. Holmes until the outcome in the Night of Joy. A combination of qualitative and quantitative methodologies has been applied to identify a series of 47 causal events that summarize all actions with an impact on plot development. Our research shows that the causal study of the novel is a useful approach that can reinforce or modify (...) qualitative assessments of previous studies. The relevance of “Night of Joy” plot within the whole narrative and its key role in the rest of the subplots are verified in numerical terms. Besides, we have expanded and quantified the causal chains operating in the novel; and we have made sure, as well, that every subplot is essential in order to reach the final outcome (with the only exception of Dr. Talc’s story). Finally, we have formulated an alternative outline of secondary plots than the ones supported by preceding research by using numeric metrics, demonstrating that “Paradise Vendors” and “Dorian Greene”, previously considered secondary storylines, exert a high impact on Confederacy’s finale, and are, perhaps, not so secondary plots after all.

We study whether the probabilistic postulate could be derived from basic principles. Through the analysis of the Strong Law of Large Numbers and its formulation in quantum mechanics, we show, contrary to the claim of the many-worlds interpretation defenders and the arguments of some other authors, the impossibility of obtaining the probabilistic postulate by means of the frequency analysis of an ensemble of infinite copies of a single system. It is shown, though, how the standard form of the probability as (...) the square of the scalar product follows from Gleason's theorem. (shrink)

Based on the results obtained from primary education students—fifth and sixth graders—the aim of this work is to check the appropriate self-perceived behaviors during and at the end of the game. The study population was made up of 698 students from fifth and sixth grade in the Autonomous Region of Castilla–La Mancha (Spain). Data were collected through a questionnaire (scale) on the social skills of primary school students linked to the adequate skills when losing, the adequate skills when winning, and (...) the adequate skills during the game. Study results revealed that analyzed behaviors vary, depending on the moment of the game, being it more frequently during the development of the game than when losing or winning. (shrink)

Reseña de la obra de Orden Jiménez, Rafael V., Humanismo Republicano Iberoamericano. Un debate. Ambrosio Velasco Gómez; José Luis Villacañas Berlanga, Madrid, Biblioteca Nueva, 2019, pp. 127.

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value of missing (...) data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms. (shrink)

There are numerous studies that, from different perspectives, have dealt with the debate held in the Spanish Empire during the 16th century on the slavery of the American Indians, starring –among others– by Francisco de Vitoria and his disciples from the School of Salamanca, and also –outside the academic sphere– by Fray Bartolomé de las Casas and Juan Ginés de Sepúlveda. The purpose of this work is to study whether this debate made its mark in Spanish society. For this, it (...) is analyzed three theatrical pieces from the Golden Age signed by playwrights of the stature of Tirso de Molina, Lope de Vega and Pedro Calderón de Barca, who –given their enormous popularity– had the capacity to reach the wide audience that congregated in the corrals of comedies. Were these three writers influenced by the controversy over the Indians carried out, among other authors, by Vitoria, Las Casas and Sepúlveda? Did they fully grasp in their works the subtle debate that Vitoria, Las Casas and Sepúlveda maintained when they interpreted Aristotelian arguments on slavery and the consequences that derived from them in terms of the possibility of enslaving or not the Indians?

La utilización de la denominación “Escuela de Salamanca” en referencia a los aspectos económicos es confusa y problemática, porque no hay argumentos convincentes para sostener que fuera una auténtica escuela de pensamiento económico (tal como la definen Schumpeter y Stigler). Sin embargo, desde Larraz y Grice-Hutchinson, los historiadores del pensamiento económico han utilizado habitualmente dicha denominación por su poder como “marca comercial” para la divulgación, y también para hacer referencia de forma breve y sencilla a las notables aportaciones analíticas de (...) un conjunto de doctores escolásticos españoles. De hecho, las monografías de los historiadores se han concentrado sobre todo en analizar las contribuciones de estos escolásticos (teoría monetaria, derechos de propiedad, etc.), más que en discutir los criterios que podrían definirles como una escuela en asuntos económicos.

The article presents a set of articles on the present and projection of the scholastic tradition. The starting point is the anthropological turn that, within scholasticism and at the beginning of the fourteenth century, privileged the study of ethics, law and politics and, consequently, the forced development of a moral theology concerned with the human coexistence. The second scholasticism, prolonging this tradition throughout the 16th and 17th centuries, could not remain oblivious to the implications of the profound changes that were (...) taking place: the Discovery of America, the Protestant Reformation, the development of a commercial proto-capitalism and the strengthening of the monarchies. As the Reformation was consolidated in a good part of the European territories, intellectual borders were raised between the various confessions. However - and this is the focus of the papers presented - these borders were porous and, despite the climate of confrontation, various indirect communication channels managed to maintain a single intellectual republic.

El presente trabajo examina la recepción de la obra del filósofo marxista e hispanista Juan Carlos Rodríguez Gómez (1942-2016), renovador del marxismo, por parte de un representante del hispanismo marxista anglosajón, el profesor Malcolm K. Read. El trabajo aborda su lectura centrándose en su último libro, pero haciendo referencias a otros trabajos anteriores. La obra de Read ofrece un punto de vista doblemente privilegiado, por el trabajo académico del autor entre la teoría y los estudios literarios y por su (...) situación en el campo universitario anglosajón, para ver tanto la potencialidad como los obstáculos de la obra de Rodríguez para su recepción fuera de España (en el marxismo anglosajón), pero también sus dificultades en la recepción interna. El presente artículo señala los aciertos de sus análisis, los complementa y matiza con algunas observaciones. (shrink)

One of the objectives in the field of artificial intelligence for some decades has been the development of artificial agents capable of coexisting in harmony with people and other systems. The computing research community has made efforts to design artificial agents capable of doing tasks the way people do, tasks requiring cognitive mechanisms such as planning, decision-making, and learning. The application domains of such software agents are evident nowadays. Humans are experiencing the inclusion of artificial agents in their environment as (...) unmanned vehicles, intelligent houses, and humanoid robots capable of caring for people. In this context, research in the field of machine ethics has become more than a hot topic. Machine ethics focuses on developing ethical mechanisms for artificial agents to be capable of engaging in moral behavior. However, there are still crucial challenges in the development of truly Artificial Moral Agents. This paper aims to show the current status of Artificial Moral Agents by analyzing models proposed over the past two decades. As a result of this review, a taxonomy to classify Artificial Moral Agents according to the strategies and criteria used to deal with ethical problems is proposed. The presented review aims to illustrate (1) the complexity of designing and developing ethical mechanisms for this type of agent, and (2) that there is a long way to go (from a technological perspective) before this type of artificial agent can replace human judgment in difficult, surprising or ambiguous moral situations.

Esta obra se concentra en cuatro temas cruciales de la formación de docentes, tanto antes como durante el servicio y en la enseñanza en diferentes áreas y niveles educativos. En primer lugar, se aborda el asunto de las creencias que los docentes tienen sobre el proceso educativo, las cuales parecen influir en la práctica profesional que estos desarrollan y, por lo tanto, deberían recibir la atención explícita de los procesos de formación de docentes que deseen promover prácticas específicas. El segundo (...) tema de la obra es la relación entre la formación de docentes y la política pública que la rige. En particular, se analizan las reformas curriculares implementadas por varias licenciaturas en universidades privadas colombianas, en respuesta a reformas a la normatividad sobre las condiciones de calidad que a las que deben ajustarse todas las licenciaturas del país. El tercer tema analizado es en qué medida los docentes en educación superior van más allá del dominio de su saber disciplinar atribuyendo importancia a la pedagogía, la didáctica y la práctica reflexiva en su propia práctica docente. Finalmente, se discuten aspectos de la formación de docentes relacionados con los procesos vividos y los retos encontrados por los docentes al entrar en la profesión, su socialización en la comunidad docente, sus identidades como maestros y su motivación para ser docentes. Vale la pena señalar que las contribuciones a este libro comparten el uso de metodologías cualitativas y presentan los resultados de historias de vida, entrevistas, observaciones, y análisis documentales, entre otros.

The concept of polarity is pervasive in natural language. It relates syntax, semantics and pragmatics narrowly, Semantics: an international handbook of natural language meaning, De Gruyter Mouton, Berlin, 2011; Israel in The grammar of polarity: pragmatics, sensitivity, and the logic of scales, Cambridge studies in linguistics, Cambridge University Press, Cambridge, 2014), it refers to items of many syntactic categories such as nouns, verbs and adverbs. Neutral polarity items appear in affirmative and negative sentences, negative polarity items cannot appear in affirmative (...) sentences, and positive polarity items cannot appear in negative sentences. A way of reasoning in Natural Language is through Natural Logic. This logic is based on the concept of polarity in order to make the meaning of a sentence weaker o stronger without changing its truth value. There exist many proposals to compute polarity in the Natural Logic context, the most widely known are the ones by: van Benthem, Sánchez-Valencia, Dowty, and van Eijck, 6th international Tbilisi symposium on logic, language, and computation, Batumi, Georgia, Springer, 2007). If Natural Logic is going to be used, as an inferential mechanism between text fragments, in Natural Language Processing applications such as text summarization, question answering, and information extraction, it is a priority to know what the existing relationship among the aforementioned algorithms is; for example, to implement the most general. We show in this paper the equivalence among the analyzed algorithms, filling a gap in Natural Logic research, particularly in computing polarity, and the soundness of their algorithms. (shrink)
