El inicio del nuevo siglo viene caracterizado en el orden económico por la desigualdad y la creciente globalización. Se han producido, en los últimos tiempos, muchos cambios, pero también permanecen viejas estructuras. La gran cantidad de privaciones existentes es uno de los rasgos más distintivos de la economía mundial actual, sobre todo en relación con el nivel de riqueza logrado, la renta que se genera y el progreso tecnológico conseguido. Analizar estas privaciones, plantear las causas de por qué se producen (...) y examinar las tendencias de la economía mundial son el objetivo central de este trabajo. El proceso de globalización neoliberal que estamos viviendo desde los años ochenta no ayuda a resolver esos viejos problemas, sino que agrava, por el contrario, la desigualdad internacional, las diferencias que se dan entre los hombres y mujeres en cuanto oportunidades y derechos, e intensifica la desigualdad dentro de los Estados-nación, incluidos la mayor parte de los países desarrollados.

The distinctive security features of the Spanish electronic national identity card, known as Documento Nacional de Identidad electrónico, allow us to propose the usage of this cryptographic smart card in an authentication framework that can be used during the registration and login phases of internet services where the validation of the user’s age and real identity are key elements, as it is the case for example of the so-called social networks. Using this mechanism with NFC-capable devices, the identity and age (...) of the potential user can be determined, allowing or denying the access to the service based on that information. (shrink)

This essay is composed of five stories written by practicing physicians about their patients. Each clinical story describes a challenging ethical condition–potential abuse of medical power, gravely ill and probably over-treated newborns, iatrogenic narcotic addiction, deceived dying people. Rather than singling out one ethical conflict to resolve or adjudicate, the authors attempt, through literary methods, to grasp the singular experiences of their patients and to act according to the deep structures of their patients' lives. Examining these five stories with simple (...) literary tools–attention to narrative frames, time, plot, and desire–reveals the mechanisms through which acts of writing and reading contribute to clinical clarity and ethical actions.

Establishing the basic knowledge, methodology, and technology for a framework for the continuous decoding of hand/arm movement intention was the aim of the ERC-funded project “Feel Your Reach”. In this work, we review the studies and methods we performed and implemented in the last 6 years, which build the basis for enabling severely paralyzed people to non-invasively control a robotic arm in real-time from electroencephalogram. In detail, we investigated goal-directed movement detection, decoding of executed and attempted movement trajectories, grasping correlates, (...) error processing, and kinesthetic feedback. Although we have tested some of our approaches already with the target populations, we still need to transfer the “Feel Your Reach” framework to people with cervical spinal cord injury and evaluate the decoders’ performance while participants attempt to perform upper-limb movements. While on the one hand, we made major progress towards this ambitious goal, we also critically discuss current limitations. (shrink)

The nonlinear differential equation governing the periodic motion of the one-dimensional, undamped, and unforced cubic-quintic Duffing oscillator is solved exactly by obtaining the period and the solution. The period is given in terms of the complete elliptic integral of the first kind and the solution involves Jacobian elliptic functions. We solve the cubic-quintic Duffing equation under arbitrary initial conditions. Physical applications are provided. The solution to the mixed parity Duffing oscillator is also formally derived. We illustrate the obtained results with (...) concrete examples. We give high accurate trigonometric approximations to the Jacobian function cn. (shrink)

The problem of knowledge evolution has received considerable attention over the years. Mainly, the study of the dynamics of knowledge has been addressed in the area of Belief Revision, a field emerging as the convergence of the efforts in Philosophy, Logic, and more recently Computer Science, where research efforts usually involve “flat” knowledge bases where there is no additional information about the formulas stored in it. Even when this may be a good fit for particular applications, in many real-world scenarios (...) different information items may be attached to formulas. For instance, when the reliability of the source of the piece of information is attached to it as a measure of some quality (e.g., strength) of the piece of information itself, or when some characteristic informs us on the desirability of the item (e.g., the potential benefit that could be obtained from it). If this type of information is available, we can use it to guide how the belief base is to be modified when new information arrives. In this work, we present a novel approach to the contraction of knowledge bases where formulas have values attached that measure some quality linked to those formulas, exploiting it to define their desirability, and uses such desirability to define which formulas need to be removed to solve conflicts. In this context, we introduce a set of properties for contraction operators by extending classic approaches. We also show how the local treatment of minimal conflicts can induce some counter-intuitive contractions, and we present a way to avoid them by considering optimal resolutions of conflicts using the additional information encoded. We show how the proposed formalization captures any contraction that is optimal under a set of features. Finally, we present a refinement based on the identification of related minimal conflicts that performs contraction in optimal ways without looking into the entire knowledge base. The approach is based on the use of the accrual of beliefs where several formulas collaboratively use their respective values to prevail in the resolution of conflicts. (shrink)

Cooperative, connected and automated mobility technologies have the potential to revolutionize transportation systems and enhance safety, efficiency and sustainability. However, the increasing reliance on digital technologies also introduces new cybersecurity risks that can compromise the safety and privacy of passengers and the integrity of transportation systems. The purpose of this article is to examine the most important threats, vulnerabilities, risks and challenges related to automated mobility and to review the status of the most promising standardization initiatives on cryptography in a (...) world where quantum computers will soon represent an actual threat.

Freely falling point-like objects converge toward the center of the Earth. Hence the gravitational field of the Earth is inhomogeneous, and possesses a tidal component. The free fall of an extended quantum mechanical object such as a hydrogen atom prepared in a high principal-quantum-number state, i.e. a circular Rydberg atom, is predicted to fall more slowly than a classical point-like object, when both objects are dropped from the same height above the Earth’s surface. This indicates that, apart from transitions between (...) quantum states, the atom exhibits a kind of quantum mechanical incompressibility during free fall in inhomogeneous, tidal gravitational fields like those of the Earth.A superconducting ring-like system with a persistent current circulating around it behaves like the circular Rydberg atom during free fall. Like the electronic wavefunction of the freely falling atom, the Cooper-pair wavefunction is quantum mechanically incompressible. The ions in the lattice of the superconductor, however, are not incompressible, since they do not possess a globally coherent quantum phase. The resulting difference during free fall in the response of the nonlocalizable Cooper pairs of electrons and the localizable ions to inhomogeneous gravitational fields is predicted to lead to a charge separation effect, which in turn leads to a large Coulomb force that opposes the convergence caused by the tidal gravitational force on the superconducting system.A “Cavendish-like” experiment is proposed for observing the charge separation effect induced by inhomogeneous gravitational fields in a superconducting circuit. The charge separation effect is determined to be limited by a pair-breaking process that occurs when low frequency gravitational perturbations are present. (shrink)

This paper is going to explore the adverse effects of exposure to combat death on medics’ holistic well-being, which, if ignored could decrease individual readiness and negatively impact the mission. We rely on the experience of United States Air Force Special Operation Surgical Teams (AF SOST) whose exposure to mass casualty scenarios in austere environments could serve as approximations of conditions of future battlefields. Over the past two decades, the ability to deliver advanced medical care on and off the battlefield (...) along with a rapid casualty evacuation platform has allowed for unprecedented survival rates exceeding 90%. While laudable, these medical achievements have also set up a casualty management paradigm in which medical decision-making singularly focuses on life-saving care. Confronting peer-peer adversaries in large scale combat operations (LSCO) on a multi-domain battlefield will make casualty management frighteningly more complex by introducing major infrastructural, personnel, and resource constraints. When considering the high number of casualties expected in LSCO alongside enormous limitations in medical resource and resupply capability, the current casualty management paradigm will not be sustainable. The resource constrained environment in LSCO will shift medical decision-making away from a singular focus on life-saving care to triage, which hinges on the ability to determine futile medical interventions—a skill that has been lost in the past two generation of combat medics. As such, a broad ethical challenge that arises in preparation for LSCO is the need to set new expectations concerning dying and death. However, medical decision-making focused on death and dying has not been explicitly addressed in military medical training, research, or policy. Relying on a body of literature known as terror management theory (TMT) and ethnographic data from our study with AF SOST medics, we are going to argue that it is important to expose medics to death in mass casualty and triage training.

Depuis une vingtaine d'annees, on assiste un peu partout a un regain d'interet pour les ecrits socratiques de Xenophon. Que Xenophon ne nous donne pas davantage que Platon un portrait historiquement fiable de Socrate peut etre considere comme un acquis de la critique du XXe siecle. Laissant transparaitre dans son temoignage des options profondement differentes de celles de Platon, Xenophon temoigne par la meme, cependant, des tensions, voire des oppositions qui traversaient le milieu socratique autour du souvenir et de la (...) comprehension de la personne de Socrate: cette seule consideration suffit a faire de Xenophon une source essentielle pour notre connaissance de l'immediat apres Socrate et, par dela, pour notre intelligence de l'histoire de la reception de Socrate dans les siecles ulterieurs. Le colloque dont sont issues les etudes rassemblees dans ce volume, organise a l'Universite de Provence (Aix-Marseille I) du 6 au 9 novembre 2003, s'inscrit dans cette perspective. Plus qu'un bilan de la nouvelle orientation des etudes xenophontiennes, qu'il est encore trop tot pour etablir, on y verra l'illustration de la diversite d'approches dont est susceptible le temoignage de Xenophon sur Socrate. Due a Louis-Andre Dorion, une bibliographie des etudes sur les ecrits socratiques de Xenophon publiees dans le dernier quart de siecle temoigne de la vitalite retrouvee de ce domaine de recherche.

Strong evidence shows that exposure and engagement with the natural world not only improve human wellbeing but can also help promote environmentally friendly behaviors. Human-nature relationships are at the heart of global agendas promoted by international organizations including the World Health Organization’s “One Health” and the United Nations “Ocean Decade.” These agendas demand collaborative multisector interdisciplinary efforts at local, national, and global levels. However, while global agendas highlight global goals for a sustainable world, developing science that directly addresses these agendas (...) from design through to delivery and outputs does not come without its challenges. In this article, we present the outcomes of international meetings between researchers, stakeholders, and policymakers from the United Kingdom and Brazil. We propose a model for interdisciplinary work under such global agendas, particularly the interface between One Health and the UN Ocean Decade and identify three priority research areas closely linked to each other: human-nature connection, conservation-human behavior, and implementation strategies. We also discuss a number of recommendations for moving forward. (shrink)

Music can reduce stress and anxiety, enhance positive mood, and facilitate social bonding. However, little is known about the role of music and related personal or cultural variables in maintaining wellbeing during times of stress and social isolation as imposed by the COVID-19 crisis. In an online questionnaire, administered in 11 countries, participants rated the relevance of wellbeing goals during the pandemic, and the effectiveness of different activities in obtaining these goals. Music was found to be the most effective activity (...) for three out of five wellbeing goals: enjoyment, venting negative emotions, and self-connection. For diversion, music was equally good as entertainment, while it was second best to create a sense of togetherness, after socialization. This result was evident across different countries and gender, with minor effects of age on specific goals, and a clear effect of the importance of music in people's lives. Cultural effects were generally small and surfaced mainly in the use of music to obtain a sense of togetherness. Interestingly, culture moderated the use of negatively valenced and nostalgic music for those higher in distress. (shrink)

Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.

The present article proposes an integration between cultural psychology and developmental science. Such an integration would draw on the cultural-psychology principle of culture-psyche interactions, as well as on the developmental-science principle of person↔︎context relations. Our proposed integration centers on acculturation, which is inherently both cultural and developmental. Specifically, we propose that acculturation is governed by specific transactions between the individual and the cultural context, and that different types of international migrants (e.g., legal immigrants, undocumented immigrants, refugees, asylum seekers, crisis migrants) (...) encounter quite different culture-psyche interactions and person↔︎context relations. We outline the ways in which various acculturation-related phenomena, such as acculturation operating at macro-level versus micro-level time scales, can be viewed through cultural and developmental lenses. The article concludes with future directions in research on acculturation as an intersection of cultural and developmental processes. (shrink)

In Spoils of War, a diverse group of distinguished contributors suggest that acts of aggression resulting from the racism and sexism inherent in social institutions can be viewed as a sort of "war," experienced daily by women of color.

This essay reports on phenomenological research conducted with people who describe having been harassed, having been accused of harassment, and/or having mediated or adjudicated harassment disputes. The authors review recent legal conceptions of sexual harassment and articulate a methodology for analyzing individual narrative accounts. The analysis of six selected interviews (three alleged harassers and three declared harassees) depicts how, through discourse with others, persons in ambiguous cases of harassment come to perceive themselves as harassers or harasseesgradually, how intention is inferred (...) from conductcontingently, and how perceptions and expressions are often reified as certainties in the effort to secure some sense of justiceinstitutionally.
