The problem of the reduction of chemistry to physics has been traditionally addressed in terms of classical structural chemistry and standard quantum mechanics. In this work, we will study the problem from the perspective of the Quantum Theory of Atoms in Molecules, proposed by Richard Bader in the nineties. The purpose of this article is to unveil the role of QTAIM in the inter-theoretical relations between chemistry and physics. We argue that, although the QTAIM solves two relevant obstacles to reduction (...) by providing a rigorous definition of chemical bond and of atoms in a molecule, it appeals to concepts that are unacceptable in the quantum–mechanical context. Therefore, the QTAIM fails to provide the desired reduction. On the other hand, we will show that the QTAIM is more similar to Bohmian mechanics and that the basic elements of both theories are closely related. (shrink)

An Aristotelian philosophy of nature offers an alternative to reduction for the conception of the inter-theoretical relationships between molecular chemistry and quantum mechanics. A basic ingredient for such an approach is an ontology of fundamental causal powers, and this work aims to develop such an ontology by drawing on quantum-chemical entities, particularly, the electron density. This notion is central to the Quantum Theory of Atoms in Molecules, a theory of molecular structure developed by Richard F. W. Bader, which describes molecules (...) and atoms in terms precisely of the electron density. Then, by identifying a philosophical tension in Bader’s discourse about the nature of electron density, the work will analyze this central notion in terms of the categorical/dispositional distinction regarding properties. The central idea is that electron density can be conceived as categorical and dispositional at once, and this very characterization can avoid Bader’s philosophical tension. (shrink)

Recent discussions about the microstructure of materials generally focus on the ontological aspects of the molecular structure. However, there are many types of substances that cannot be studied by means of the concept of molecule, for example, salts. For the quantum treatment of these substances, a new particle, called phonon, is introduced. Phonons are generally conceived as a pseudo-particle, that is, a mathematical device necessary to perform calculations but which does not have a “real” existence. In this context, the aim (...) of this paper will be to analyze the ontological status of phonons. For such purposes we will critically analyze the arguments that would account for the presumed nonexistence of phonons. Finally, having already demonstrated that there are not enough reasons to consider phonons as non-existing entities, we will explore some possibilities that allow us to elucidate their ontological status.

The problem of the 3N dimensions of the wave function is of particular interest in the philosophy of physics. In this work, we will recall the main positions about the nature and dimensionality of the wave function and we will introduce a new perspective, coming from quantum chemistry. For this, we will bring to light the formal operations that underlie the independent electron approximation. On this basis, we will point out how quantum chemistry can offer new arguments that contribute to (...) the debate about the ontology of wave function. (shrink)

By moving away from the traditional reductionist reading of the quantum theory of atoms in molecules, in this paper we analyze the role played by QTAIM in the relationship between molecular chemistry and quantum mechanics from an emergentist perspective. In particular, we show that such a relationship involves two steps: an intra-domain emergence and an inter-domain emergence. Intra-domain emergence, internal to quantum mechanics, results from the fact that the electron density, from which all the other QTAIM’s concepts are defined, arises (...) from the wavefunction as a coarse-grained magnitude. Inter-domain emergence involves an analogical link, a mapping, between QTAIM’s entities, such as topological atoms and bond paths, and the entities that populate the molecular-chemistry domain, such as chemical atoms and chemical bonds.

In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

Since March 14, 2020, Spanish citizens have been confined to their homes due to the impact of the COVID-19 pandemic. Participating in musical activities has been associated with reduced anxiety and increased subjective wellbeing. The aim of this study is to analyze how Spanish citizens used music during the lockdown period. We also study perceptions of the impact music has in everyday life, in particular examining the respondents’ insights into the effects of listening to music in situations of isolation. The (...) study was conducted using the MUSIVID19 questionnaire administered to a total of 1868 Spanish citizens. The results indicate that during lockdown, respondents perceived an increase in the time they devoted to musical activities such as listening, singing, dancing or playing an instrument. The participants also reported using music to cope with the lockdown, finding that it helped them to relax, escape, raise their mood or keep them company. The findings suggest an improvement in their perception of the value of music in personal and social wellbeing during the lockdown. However, the study reveals significant differences in the use and perceptions of music according to respondents’ personal situations. Age and feelings of vulnerability may lead to more conservative uses of musical practice and to more moderate perceptions of the positive values of music. (shrink)

This study aims to test the theoretical model of career adaptability of refugees to investigate the dynamics of successful resettlement. The theoretical model is grounded on career construction and social network theory. We employ quantitative and qualitative methodologies to test the model in a sample of Venezuelans living and working in Colombia. The quantitative results provide partial support for Campion’s model. However, we test an alternative model and find that career adaptability has a direct relationship with subjective resettlement. In addition, (...) cultural identification plays a buffering role on the harmful effects of discrimination on subjective resettlement. Qualitative results from eight in-depth interviews shed light on the process of refugee resettlement, thus revealing the role of social networks. Our study contributes to previous research on refugees by testing, adapting, and expanding a novel model of work resettlement and focusing on a group of refugees transitioning from one emerging country to another emerging country.

En el siguiente artículo se presenta una investigación filosófica acerca de la conformación ontológica delmundo virtual. Esta es un aporte teórico al debate contemporáneo de la filosofía de la computación sobrela caracterización ontológica de la computación digital y sus productos emergentes, ya que se propone unaaproximación a este campo de estudio desde la perspectiva filosófica de Nicolaï Hartmann. El objetivo principal del presente artículo es explicar la estratificación del mundo virtual a partir de la teoría ontológica de estratos y categorías (...) de Hartmann. Para cumplir con este objetivo se procedió a una revisión crítica del estado de la cuestión de la ontología filosófica de la virtualidad. Luego se procedió a presentar una propuesta de estratificación y categorización denominada ‘La fábrica del mundo virtual’ que es una ontología hermenéutica de la virtualidad digital basada en los postulados de Hartmann. Las principales conclusiones alcanzadas son: i) La emergencia de la realidad del mundo virtual se encuentra constituida de los mismos estratos que conforman la esfera del conocimiento del mundo real: material, orgánico, psíquico y social. ii) La realidad virtual es un producto de la computación que ocurre en la esfera del conocimiento en el que existe intervención de la esfera ideal y de la esfera del mundo real.

_This article presents the main ethical challenges faced by social work professionals in Spain during the "first wave" of COVID-19 in 2020. The pandemic had a serious impact not only on the health sector, but also in the field of social work. During this time, social workers had to address serious ethical questions regarding issues such as confidentiality breaches, how to fairly distribute available resources, the lack of personal contact and emotional connection with the service users, the difficulties of working (...) in isolation and online, doubts about the reliability of the information they were handling and the difficulty of making proper diagnoses. An international research group led by Dr. Sara Banks conducted a broader research project in collaboration with the International Federation of Social Workers, which collected information through an online questionnaire aimed at social workers from various countries. In this article we analyse the results related to the main ethical challenges faced by social workers in Spain. The research group identified two types of ethical challenges that they have separated into two sections: the first section is related to direct intervention with users, which includes topics such as the lack of emotional support, reliability, use of technology, the appropriate care, compliance with the highest professional standards, confidentiality, vulnerability, and the fair distribu-tion of resources. The other section is related to the ethical challenges around the daily work within social entities, which involved dealing with issues such as the e-social work and coordination difficulties, the management of pressure in social bodies and changes in the intervention methodology__._ _Keywords_: Social work ethics, pandemic, international research, COVID.

Background Providing understandable information to patients is necessary to achieve the aims of the Informed Consent process: respecting and promoting patients’ autonomy and protecting patients from harm. In recent decades, new, primarily digital technologies have been used to apply and test innovative formats of Informed Consent. We conducted a systematic review to explore the impact of using digital tools for Informed Consent in both clinical research and in clinical practice. Understanding, satisfaction and participation were compared for digital tools versus the (...) non-digital Informed Consent process. Methods We searched for studies on available electronic databases, including Pubmed, EMBASE, and Cochrane. Studies were identified using specific Mesh-terms/keywords. We included studies, published from January 2012 to October 2020, that focused on the use of digital Informed Consent tools for clinical research, or clinical procedures. Digital interventions were defined as interventions that used multimedia or audio–video to provide information to patients. We classified the interventions into 3 different categories: video only, non-interactive multimedia, and interactive multimedia. Results Our search yielded 19,579 publications. After title and abstract screening 100 studies were retained for full-text analysis, of which 73 publications were included. Studies examined interactive multimedia, non-interactive multimedia, and videos, and most studies were conducted on adults. Innovations in consent were tested for clinical/surgical procedures and clinical research. For research IC, 21 outcomes were explored, with a positive effect on at least one of the studied outcomes being observed in 8/12 studies. For clinical/surgical procedures 49 outcomes were explored, and 21/26 studies reported a positive effect on at least one of the studied outcomes. Conclusions Digital technologies for informed consent were not found to negatively affect any of the outcomes, and overall, multimedia tools seem desirable. Multimedia tools indicated a higher impact than videos only. Presence of a researcher may potentially enhance efficacy of different outcomes in research IC processes. Studies were heterogeneous in design, making evaluation of impact challenging. Robust study design including standardization is needed to conclusively assess impact. (shrink)

Este artículo explora el concepto de trauma colectivo y su aplicación en el contexto histórico y social de las sociedades latinoamericanas. La transferencia del término «trauma colectivo» desde el campo del conocimiento psicológico a la esfera social e histórica plantea preguntas sobre su legitimidad y marco conceptual. El estudio examina la fidelidad de esta transferencia conceptual y su relación con la comprensión psicoanalítica temprana de los fenómenos traumáticos. El contexto cultural europeo de finales del siglo xix y principios del siglo (...) xx proporcionó la base para teorizar las consecuencias de experiencias intensas y violentas, lo que resultó en el concepto de «neurosis traumática», influenciado significativamente por el trabajo de Freud. El artículo discute la apropiación de herramientas psicoanalíticas en la crítica histórica y cultural para comprender eventos que desafían marcos tradicionales y la inteligibilidad social, como el Holocausto. La noción del trauma como una fuerza enigmática y recurrente en la experiencia histórica se explora a través del enfoque de los estudios del trauma. El artículo pone de relieve a destacados y destacadas académicas en este campo y su uso de conceptos psicoanalíticos, demostrando la preservación y aplicación significativa de estas nociones en la comprensión de fenómenos históricos y colectivos. Al acortar la brecha entre las experiencias psicológicas individuales y los traumas colectivos, los estudios del trauma ofrecen un enfoque único para interpretar y representar eventos que resisten las narrativas históricas tradicionales.

In this research, a sliding mode regulator with sine mapping is suggested for the stabilization of electricity generators being affected by magnet interaction nonlinearities and generator nonlinearities. To reach this goal, our suggested regulator has the following contributions: it starts from the sliding mode regulator with the modifications that the saturation mapping is used to reach a smoother performance instead of the signum mapping, and the sine mapping is applied to reach an upper bound in the proportional gain error, it (...) is used to reach some chosen constant behaviors for the angle position, angle speed, and current in the electricity generators, and its stabilization is ensured based on the Lyapunov approach. We show the simulation of the suggested regulator in two electricity generators. (shrink)

Vital events, such as widowhood and retirement, are broadly accepted as points of inflection in the lives of older adults that often differ according to gender. In this study, we analyzed the influence of gender differences in meaningful leisure among older adults through the integration of qualitative and quantitative findings. The use of joint displays revealed that: (1) there is no significant difference between the influence of retirement and widowhood on the two genders, (2) the ethic of care is a (...) constraining factor in older women’s leisure, (3) women are more innovative in their leisure in older age, and (4) volunteer activities are highly segregated by gender. The use of joint displays helped illuminate these four phenomena in light of quantitative and qualitative data. (shrink)

La constitución de Jesús en el pensamiento de Ibn ‘Arabī depende de su herencia materna y paterna. El ángel Gabriel toma el estatuto de padre por su aparición a María y por ser el portador de un “Espíritu que procede de Dios”. En este artículo presentaremos la herencia que Jesús recibe del ángel y las repercusiones que sobre su ser tendrá el encuentro de una madre humana y un espíritu angélico. Jesús va a ser un ser dual sobre el que (...) va a primar su aspecto espiritual, puesto que el “agua imaginal” de Gabriel primará sobre el “agua real” de María. Será medio humano y medio espíritu. Su “cristología” es plenamente islámica, pero se acerca, de esta manera, sin identificarse, al docetismo. Jesús aparecerá como un varón, aun siendo un espíritu, y será, por ello, capaz de obrar milagros de vivificación. Para el gran maestro sufí, cada profeta es manifestador de una cualidad divina; en el caso de Jesús, él es la corporalización del Aliento divino. (shrink)

En este artículo se analiza una recreación quijotesca en la novela de Graham Greene Monseñor Quijote. Para ello se utilizan dos términos procedentes del Derecho romano: los conceptos de autoridad y poder. En esta obra de Greene, la autoridad surge de los libros o de autores de libros, cuya lectura permite que la vida siga teniendo sentido. En Greene encontramos la estrategia de lectura conocida como las sortes virgilianae que permite a los personajes orientarse en las dificultades diarias. Sin embargo, (...) el poder está caracterizado por su condición iletrada, la ausencia de libros y su ignorancia. In this article a novel by Graham Greene entitled Monsignor Quixote is analysed, a book that involves a recreation of the novel by Cervantes. The author of this article employs two concepts from Roman law: authority and power in his analysis. In this work by Greene, authority arises from the books or the book writers, whose reading allows life to keep making sense. In Greene, a strategy of reading known as the sortes virgilianae is found and this allows the characters to get their bearings in the daily difficulties. However, power is described as illiterate, the absence of books and ignorance. (shrink)

«Tu ne pourras voir mon visage, parce que personne ne peut me voir et demeurer vivant» . La théologie de Jean nous explique que le visage du Père se révèle en Jésus, conséquence de la foi en l'Incarnation. Mais Lessing, en plein siècle des Lumières, dénonçait le large fossé séparant le Christ de la foi du Jésus de l'histoire. L'A. propose une enquête christologique, qui va de l'Illuminisme à nos jours, pour déterminer ce qu'il nous reste de la recherche du (...) visage de Jésus, sur la base des nombreux portraits qu'offrent les Ecritures. La leçon qui en ressort est que Jésus Christ ne se prête à aucune forme de manipulation fondée sur des idéologies philosophiques ou des préjudices historiques. Les Ecritures doivent être comprises dans le même esprit avec lequel elles ont été écrites. (shrink)
