El término red social se ha utilizado para denotar conjuntos complejos de relaciones entre miembros de los sistemas sociales en todas las dimensiones, desde el ámbito interpersonal hasta el internacional. Los jóvenes utilizan las redes sociales como un elemento de comunicación a través de las Nuevas Tecnologías. Estos espacios virtuales son una evasión para ellos, pero hay que alertar a los menores del peligro de revelar datos personales a través de Internet.

En la serie de cuadernos del seminario de la Universidad Nacional Autónoma de México, “Modernidad: versiones y dimensiones”, dirigido por Marta Lamas y que ha sido coordinado anteriormente por Raquel Serur y por su fundador Bolívar Echeverría, Andrés Luna Jiménez, un joven historiador, ha publicado un libro notable: Figuras de la crítica: la (de)formación del sujeto como problema histórico en Marcuse, Foucault y Butler. El libro contiene virtudes difíciles de alcanzar en la academia actual: muestra una clara voz autoral; un (...) hilo argumental sostenido, profundo y, a la vez, pedagógico; y actualiza con sutileza los debates, los enfrenta y los coloca bajo una perspectiva abierta a la investigación filosófica contemporánea.

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.

Background:The first wave of the COVID-19 pandemic caused a shortage of qualified nurses in Spain. As a result, the government authorized the hiring of senior students.Objectives:To explore the ethical dilemmas and ethical conflicts experienced by final-year nursing students who worked during the first outbreak of the COVID-19 pandemic in Spain.Research design:A qualitative exploratory study was conducted using purposive sampling. Semi-structured interviews were carried out using a question guide. Interviews took place via a private video chat room platform. A thematic, inductive (...) analysis was performed of the information gathered.Participants and research context:Eighteen nursing students were recruited from two universities of Madrid, aged between 18 and 65 years old, enrolled in the fourth year of nursing studies and who were hired under a relief contract for health professionals during the pandemic.Ethical considerations:The present study was carried out in accordance with the Declaration of Helsinki, and the study was approved by the Local Ethics Committee of Universidad Rey Juan Carlos.Results:Three specific themes emerged: (a) coping with patient triage, (b) difficulties in providing end-of-life care, and (c) coping with patient death. Nursing students participated in the process of patient selection for resource allocation and ICU bed occupancy. They were shown how to care for patients who were not admitted to the ICU, in their last moments and were faced with the difficulties of applying end-of-life care. Finally, the nursing students were confronted with the death of their patients, in overwhelming numbers and under adverse conditions.Conclusions:These findings can help shed light on the ethical dilemmas and ethical conflicts faced by novice nursing students, incorporated into the workforce during the COVID-19 pandemic. Moreover, it was described that students may normalize the death due to the exhaustion and overwhelmed routine. (shrink)

Multisensory Experiences: Where the senses meet technology takes you on a journey that goes from the fundamentals of multisensory experiences, through the relationship between the senses and technology, to what the future of those experiences may look like, and our responsibility in it.

Este artículo se adentra en los temas y tópicos vitales de la obra literaria de Eliacer Cansino, escritor dedicado a la literatura juvenil, e invita a reflexionar sobre cómo su lectura puede desarrollar el pensamiento crítico de los jóvenes lectores del siglo XXI. Para abordar esta investigación, se ha recurrido a una metodología de corte cualitativo, con especial atención a la narrativa biográfica. De esta manera, dado que literatura y realidad constituyen dos caras de una moneda al forjar lectores, se (...) analizó el perimundo literario de Eliacer Cansino. Los resultados justifican que la lectura de la obra de este autor es un referente literario para el desarrollo del pensamiento crítico desde la experiencia lectora de los adolescentes. (shrink)

Resumen En este trabajo se analizan las pautas de elección entre los cuatro paradigmas gramaticales de segunda persona del español peninsular (los prototípicos, representados por los pronombres tú y vosotros, y los desplazados, por usted y ustedes), cuando se usan para indexar a interlocutores específicos, en un corpus de discurso radiofónico de la ciudad española de Salamanca. Se plantea la hipótesis de que los fundamentos cognitivos de las personas gramaticales se proyectan en su potencial sociopragmático como recursos para la configuración (...) de identidades contextuales. Tras clasificar a los participantes del corpus en cuatro tipos de identidad socioprofesional recurrentes en la comunicación radiofónica (locutores, personajes públicos, políticos y hablantes particulares), se calculan las frecuencias con que cada tipo dirige y recibe cada tratamiento de segunda persona. El análisis cuantitativo constituye un punto de partida para la observación cualitativa de los contextos de uso. Tras este se concluye que la elección entre las cuatro formas de segunda persona combina los parámetros sociopragmáticos de cercanía-distancia (que afecta a la elección entre formas prototípicas y desplazadas) e individualidad-grupalidad (que afecta a la elección entre formas singulares y plurales). Tales parámetros remiten, a su vez, al continuum discursivo-cognitivo entre la subjetividad y la objetividad. (shrink)

The purpose of this article is to analyze Spanish first-person plural subjects as a cognitively grounded grammatical choice serving various discursive functions. Both the expressed and omitted variants of the subject will be considered, even if omission is by far the more frequent choice in Spanish and the more communicatively versatile one. The particularly vague reference of omitted nosotros ‘we’ – always involving an extension of the self towards a wider notional scope – results in a remarkable variety of possible (...) contextual projections. It can be used to signal speaker identities as well as manage interpersonal relationships through the iconic suggestion of viewpoint coincidence. First-person plural clauses are quantitatively and qualitatively investigated across two corpora of contemporary Spanish comprising a variety of spoken and written genres. It is found that, aside from the basic distinction between hearer-exclusive and hearer-inclusive first persons, a third, intermediate variant can be considered, that of empathic hearer-exclusive uses. These are typical of interactions where involvement of the audience is sought even if they are not referentially included in the subject, as is usual in some varieties of spoken mass-media discourse. Each one of the referential variants is used with different frequencies and contextual repercussions, depending on the socio-functional demands and goals of particular textual genres. (shrink)

Many of the computing systems programmed using Machine Learning are opaque: it is difficult to know why they do what they do or how they work. Explainable Artificial Intelligence aims to develop analytic techniques that render opaque computing systems transparent, but lacks a normative framework with which to evaluate these techniques’ explanatory successes. The aim of the present discussion is to develop such a framework, paying particular attention to different stakeholders’ distinct explanatory requirements. Building on an analysis of “opacity” from (...) philosophy of science, this framework is modeled after accounts of explanation in cognitive science. The framework distinguishes between the explanation-seeking questions that are likely to be asked by different stakeholders, and specifies the general ways in which these questions should be answered so as to allow these stakeholders to perform their roles in the Machine Learning ecosystem. By applying the normative framework to recently developed techniques such as input heatmapping, feature-detector visualization, and diagnostic classification, it is possible to determine whether and to what extent techniques from Explainable Artificial Intelligence can be used to render opaque computing systems transparent and, thus, whether they can be used to solve the Black Box Problem.

In this contribution, I critically discuss the thesis, advanced by some recent writers, that nonreductive physicalists can solve the problem of causal exclusion by resorting to the metaphysical notion of grounding. After discussing the many problems confronted by very recent versions of this proposal, I conclude that a version of Nonreductive Physicalism framed in terms of a notion of realization of properties is in a better position than Grounding Physicalism in order to successfully deal with a notoriously complex metaphysical issue (...) such as the causal exclusion problem.

In this paper, we present another case study in the general project of proof mining which means the logical analysis of prima facie non-effective proofs with the aim of extracting new computationally relevant data. We use techniques based on monotone functional interpretation developed in Kohlenbach , Oxford University Press, Oxford, 1996, pp. 225–260) to analyze Cheney's simplification 189) of Jackson's original proof 320) of the uniqueness of the best L1-approximation of continuous functions fC[0,1] by polynomials pPn of degree n. Cheney's (...) proof is non-effective in the sense that it is based on classical logic and on the non-computational principle WKL . The result of our analysis provides the first effective uniform modulus of uniqueness . Moreover, the extracted modulus has the optimal ε-dependency as follows from Kroó 331). The paper also describes how the uniform modulus of uniqueness can be used to compute the best L1-approximations of a fixed fC[0,1] with arbitrary precision. The second author uses this result to give a complexity upper bound on the computation of the best L1-approximation in Oliva 66–77). (shrink)

The received view of dynamical explanation is that dynamical cognitive science seeks to provide covering law explanations of cognitive phenomena. By analyzing three prominent examples of dynamicist research, I show that the received view is misleading: some dynamical explanations are mechanistic explanations, and in this way resemble computational and connectionist explanations. Interestingly, these dynamical explanations invoke the mathematical framework of dynamical systems theory to describe mechanisms far more complex and distributed than the ones typically considered by philosophers. Therefore, contemporary dynamicist (...) research reveals the need for a more sophisticated account of mechanistic explanation. (shrink)

Models developed using machine learning are increasingly prevalent in scientific research. At the same time, these models are notoriously opaque. Explainable AI aims to mitigate the impact of opacity by rendering opaque models transparent. More than being just the solution to a problem, however, Explainable AI can also play an invaluable role in scientific exploration. This paper describes how post-hoc analytic techniques from Explainable AI can be used to refine target phenomena in medical science, to identify starting points for future (...) investigations of causal relationships, and to generate possible explanations of target phenomena in cognitive science. In this way, this paper describes how Explainable AI—over and above machine learning itself—contributes to the efficiency and scope of data-driven scientific research. (shrink)

We present a new functional interpretation, based on a novel assignment of formulas. In contrast with Gödel’s functional “Dialectica” interpretation, the new interpretation does not care for precise witnesses of existential statements, but only for bounds for them. New principles are supported by our interpretation, including the FAN theorem, weak König’s lemma and the lesser limited principle of omniscience. Conspicuous among these principles are also refutations of some laws of classical logic. Notwithstanding, we end up discussing some applications of the (...) new interpretation to theories of classical arithmetic and analysis. (shrink)
