Es importante destacar que cuando en la historia de la física se hace referencia al problema de si la luz se transmite de manera instantánea o si requiere de tiempo –que se abreviará aquí como el problema de la propagación sucesiva de la luz– siempre destacan ciertos personajes: por un lado, Armand Hippolyte Louis Fizeau y Jean Bernard León Foucault, quienes en el siglo XIX lograron medir por primera vez de forma precisa la velocidad de la luz; y por otro, (...) los astrónomos Ole Christensen Roemer y James Bradley, quienes en los siglos XVII y XVIII –respectivamente– fueron los primeros en dar una respuesta derivada de trabajos observacionales de que la luz sí requiere de tiempo en su transmisión, esto es, que su propagación es sucesiva. Entre estos nombres, aparece siempre de forma algo etérea Galileo Galilei como el primero que propuso un enfoque experimental para dar respuesta a esta pregunta. (shrink)

Following González Vergara (2006a, 2009, 2012), the presence of the morpheme se in Spanish is explained by a lexical phenomenon that modifies the logical structure of sentences in which it appears. This phenomenon decreases the importance of the Actor and favors the Undergoer. According to this proposal, this phenomenon expresses itself, in most of the Spanish sesentences, as a lexical rule that makes unspecific the highest ranking argument. Taking the above as a basis, this paper explores and proposes explanations (...) for se alternating verbs of the type of matar(se), morir(se), dormir(se), despertar(se), terminar(se), adelgazar(se), engordar(se), envejecer(se), mejorar(se), controlar(se), crecer(se) y aparecer(se) in the framework of the Role and Reference Grammar.

Purpose As part of an international study of knowledge of and attitudes to Snowden’s revelations about the activities of the National Security Agency/Government Communications Headquarters, this paper aims to deal with Mexico, taking its socio-cultural and political environment surrounding privacy and state surveillance into account. Design/methodology/approach A questionnaire was answered by 160 Mexican University students. The quantitative responses to the survey were statistically analysed as well as qualitative considerations of free text answers. Findings Snowden’s revelations have had a limited influence (...) over Mexican youngsters’ attitudes toward privacy and state surveillance, although there is a great awareness by Mexican young people of individual rights issues. Practical implications The study results imply a need to build a collective awareness of the importance of the right to privacy and its responsibilities, the available technological options for individuals to exert their own privacy and security and the democratic means to agree and enforce appropriate legal restrictions on state surveillance. Social implications The results of this study based indicate an urgent necessity for providing Mexican youngsters with opportunities to learn more about privacy, liberty, individual autonomy and national security. Originality/value This study is the first attempt to investigate the social impact of Snowden’s revelations on Mexican students’ attitudes toward privacy and state surveillance as part of cross-cultural analyses between eight countries.

The aim of this paper is to prove how what is apparently a mistake made by Plutarch, wheter deliberate or not, in his reference to the arson attack of Caesar´s soldiers in Alexandria as the end of the famous Library, show us the common sense of the term “bibliotheke” from that time up to now. Coming to this conclusion has required a detailed analysis of the Library of Alexandria since its birth applying Aristotelian doctrine to its configuration not only as (...) an organized space for books but also as an imaginary reading room from which the helenistic world of relations is established. In a second approach, we focus the attention on the change occurred in this collection with the introduction of alphabetical order and, then, with the philological activity of Callimachus. As a result of his Pinakes, the platonic concept of daimon, “guide”, became the first characteristic o a philologist or librarian. Using the information ordered in the Pinakes anybody could be a librarian and find a library anywhere. The old megále bibliotheke of Alexandría remains only with the idea of the conservation of original papyrus. This is de reason of the enigmatic sentence of Plutarch announcing the end of this situation caused by the action of the fire. (shrink)

Las tierras arrasadas de Emiliano Monge se encuentra entre el creciente corpus de novelas y películassobre los migrantes centroamericanos y los diferentes tipos de violencia que afrontan. Monge aborda en esta obra los efectos de la militarización en la política migratoria de México, impulsada por la guerra contra el narco que comenzó en 2006. Esta novela lleva a cabo un desmonte crítico del humanitarismo literario al tiempo que enfatiza la vulnerabilidad de los migrantes y su agencia. En tal sentido, se (...) explora la forma en la que, en cuanto ficción posthumanitaria, la novela encarna las diferentes formas en que opera el orden necropolítico en la vulnerabilidad de estos migrantes centroamericanos indocumentados a lo largo de su periplo.

Background: In the last decades, there have been important developments in the scientific and technological areas of healthcare. On certain occasions this provokes conflict between the patients' rights and the values of healthcare professionals which brings about, within this clinical relationship, the problem of conscientious objection. Aims: To learn the opinions that the Nurses of the Madrid Autonomous Community have regarding conscientious objection. Research design: Cross-cutting descriptive study. Participants and research context: The nurses of 9 hospitals and 12 Health Centers (...) in the Madrid Autonomous Community. The study was done by means of an auto completed anonymous questionnaire. The variables studied were social-demographical and their opinions about conscientious objections. Ethical considerations: The study was approved by the Ethical Community of Clinical Research of the University Hospital Príncipe de Asturias. Participants were assured of maximum confidentiality and anonymity. Findings: A total of 421 nurses answered the questionnaire. In total, 55.6% of the nurses confirmed they were religious believers, and 64.3% declared having poor knowledge regarding conscientious objection. The matters that caused the greatest objections were voluntary abortions, genetic embryo selection, refusal of blood transfusions, and therapy refusal. Discussion: Different authors state that the most significant cases of conscientious objections for health professionals are those regarding carrying out or assisting in abortions, euthanasia, the practice of assisted reproduction and, finally, the prescription and dispensing of the morning-after pill. In our study, the most significant cases in which the nurses would declare conscientious objections would be the refusal to accept treatment, the selection of embryos after genetic diagnosis preimplantation, the patient’s refusal to receive blood transfusions due to religious reasons and pregnant women’s request for voluntary abortions within the first 14 weeks. Conclusion: Nurses’ religious beliefs influence their opinions regarding conscientious objection. The nurses who declare themselves as religious believers object in a higher percentage than those without religious beliefs. (shrink)

Aberrations introduced by the atmospheric turbulence in large telescopes are compensated using adaptive optics systems, where the use of deformable mirrors and multiple sensors relies on complex control systems. Recently, the development of larger scales of telescopes as the E-ELT or TMT has created a computational challenge due to the increasing complexity of the new adaptive optics systems. The Complex Atmospheric Reconstructor based on Machine Learning is an algorithm based on artificial neural networks, designed to compensate the atmospheric turbulence. During (...) recent years, the use of GPUs has been proved to be a great solution to speed up the learning process of neural networks, and different frameworks have been created to ease their development. The implementation of CARMEN in different Multi-GPU frameworks is presented in this paper, along with its development in a language originally developed for GPU, like CUDA. This implementation offers the best response for all the presented cases, although its advantage of using more than one GPU occurs only in large networks. (shrink)

This paper proposes freedom as the condition of possibility for the construction of trust in human relationships. The methodology used is a review of the scientific literature of the most recent moral and political philosophy. As a result of the dialogue between different positions, it is discovered that freedom, despite being present in the act of trust, is forgotten in the discussion around trust, a forgetfulness that has as its main causes the assumption that trust is natural and the confusion (...) between the propensity to trust and the act of trusting. All this leads to proposing an approach of the act of trusting that starts from the freedom of the trustee and the trustor. (shrink)

Resumen Este artículo tiene por objetivo exponer cómo la contaduría como profesión puede ampliar su horizonte de reflexión sobre el concepto de bien común fundamentándose en los postulados principales de la Doctrina Social de la Iglesia dentro de su horizonte interpretativo, para lo cual se basa en una metodología cualitativa y un método dialógico fundamentado en la hermenéutica gadameriana. El principal aporte de este estudio es proponer que la contaduría, basada en el bien común desde la Doctrina Social de la (...) Iglesia, tiene que cambiar de paradigma, generar y comunicar información financiera y no financiera orientada hacia todo el hombre y a todos los hombres, y estar orientada hacia la eco-nomía y la eco-logía. Abstract This paper aims to expose how accounting as a profession can broaden its horizon of reflection on the concept of common good based on the main postulates of the Catholic Social Teaching within its interpretive horizon, for which it is based on a qualitative methodology and a dialogic method founded on Gadamerian hermeneutics. The main contribution of this study is to propose that accounting, based on the common good from the Catholic Social Teaching, must change the paradigm, generate and communicate financial and non-financial information oriented towards all man and all men, and be oriented towards eco-nomy and eco-logy.

Adults (more than 18 years old) are likely to reproduce the habits that they acquired during childhood and adolescence (from 6 to 16 years old). For that reason, teachers and parents have the responsibility to promote an active and healthy lifestyle in children and adolescents. Even though every school subject should promote healthy activities, Physical Education (PE) is the most important subject to foster well-being habits associated to healthy lifestyle during sport practice and other kinds of active tasks. Indeed, there (...) are many factors that influence the acquisition of healthy habits that should be taken into account when programs and activities are implemented in both educational and extracurricular context. In this sense, psychological and social factors are of utmost importance to achieve optimal experiences for an active and healthy lifestyle. However, due to the myriad of studies analyzing different factors in different contexts, there could be confusion when programs and pedagogical strategies are applied in educational or extracurricular contexts. The objective of this investigation is to analyze the state of art of the psychosocial factors which influence the engagement in physical activities and sport practice. The keywords used in this review were mainly: ‘Self-Determination Theory’, ‘motivation’, ‘Psychological need satisfaction, ‘physical activity and sport engagement’, ‘Elementary Education’, ‘Secondary Education’, ‘Physical Education’. The articles were selected according to the following criteria: (a) peer-reviewed original research published in international journals indexed in JCR or SJR, (b) published in English or Spanish, (c) about psychosocial factors which influence the physical activity and sport engagement, (b) in educational or extracurricular context. Research articles selected were found through nine databases. It was observed that physical activities and sport practice engagement are closely related to psychological factors. In particularly, intrinsic motivation was able to determine the active participation in any activity, including physical activity and sport practice during the implementation of Small-Sided Games and other kinds of pedagogical strategies (e.g., Pedagogical Models). Motivation was also closely related to flow state. Finally, these variables should be considered in order to organize effective programs to promote an active and healthy lifestyle in Physical Education classes. (shrink)

El presente artículo indaga los orígenes de una valoración positiva de toda la condición humana en el incipiente Renacimiento. Centrándonos en _De dignitate et excellentia hominis_ de Gianozzo Mannetti situamos su pensamiento frente a la tradición, mostrando la radical originalidad de su enfoque, fuertemente influenciado por el aristotelismo. Con tal fin, mostramos dos tradiciones que dignifican la condición del hombre: una griega, que se ordena en torno al concepto de microcosmos, y otra latina, edificada sobre el término _dignitas_. Proponemos que (...) abandonando la tradición griega, se conduce la tradición latina a un horizonte muy distinto, transformando el término clásico de _dignitas_ de un término equívoco a uno análogo.

Esta investigación tiene como finalidad responder, desde la filosofía y literatura de Camus, la pregunta de si el hombre puede ser feliz sin Dios. Para llevar a cabo este trabajo, se utiliza un método hermenéutico, pues se hace un acercamiento dialógico y holístico a las obras del pensador argelino para descubrir su pensamiento respecto a Dios y a la felicidad humana. Los principales resultados de la investigación concluyen que el hombre puede ser feliz sin Dios en la medida en que, (...) en primer lugar, acepte el absurdo y viva su rebeldía, y, en segundo lugar, comprenda la felicidad como una vocación ontológica más allá de un estado.

[Recipient of the 2024 Inter-American Philosophy Award] Philosophers have recently debated whether the social identity category "Latinx" picks out a race (Alcoff 2006), an ethnicity (Gracia 2008), or something else altogether (Arango and Burgos 2021). Rather than defending one or several of these ways of understanding US Latinx as a political or social group, my paper focuses on the personal social identity turmoil young US Latinx people feel and explores the history of inter-American thought to seek a remedy for it. (...) Three prominent American philosophers – José Martí, Alain Locke, and Emilio Uranga – combine to teach us that, while the US Latinx strives for belonging, they find themselves in a situation of unbelonging. The tension that results from the desire to belong but the reality of unbelonging produces a deep-seated anxiety that has come to characterize the US Latinx condition. I suggest that an effective tool for coping with this anxiety, affirming our identity, and building community is the activity of doing inter-American, Latin American, and Latinx Philosophy. (shrink)
