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.

La poesía de Magdalena Camargo Lemieszek es una de las más importantes de la región actualmente. Dueña de una poesía donde los paisajes oníricos convergen con la sonoridad de un verbo insoslayablemente poderoso, lleva al lector a diversas esferas de la memoria, ahí donde el ser humano presenta su vulnerabilidad, su estado primigenio, y le devuelve quizás esa dignidad perdida en la infancia, tópico que se presenta en su obra, pero con giros hacia su estado presente, hacia una pregunta incómoda (...) sobre el ser, sus virtudes y sus momentos trágicos. Es para resumirlo de una manera, una obra que no es complaciente y no deja indiferente a nadie. (shrink)

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)

What are the limits of the use of artificial intelligence (AI) in the relational aspects of medical and nursing care? There has been a lot of recent work and applications showing the promise and efficiency of AI in clinical medicine, both at the research and treatment levels. Many of the obstacles discussed in the literature are technical in character, regarding how to improve and optimize current practices in clinical medicine and also how to develop better data bases for optimal parameter (...) adjustments and predictive algorithms. This paper argues that there are also in principle obstacles to the application of AI in clinical medicine and care where empathy is important, and that these problems cannot be solved with any of the technical and theoretical approaches that shape the current application of AI in specific areas of clinical medicine in which care for patients is fundamental. This is important, because it generates specific risks that may be overlooked otherwise, and it justifies the necessity of human monitoring and emotional intervention in clinical medicine. Consequently, difficult issues concerning moral and legal responsibility may ensue if these in principle problems are ignored. (shrink)

The objective of the present review on the evolution of Green Chemistry, since its emergence until 2016, aimed an integrated vision of its progress along the three phases of its development: emergence, divulgation and consolidation. The methodology involved the analysis of a selection of bibliography on the evolution of GC collected from issues of the ACS symposia series; editorials in specialized GC journals; and commemorative birthday papers/editorials of these journals and of the GC itself. The analysis allowed to identify and (...) discuss the characteristics and conceptions of GC agents about fundamental concepts and procedures, in order to visualize and better understand the state of knowledge and the subject areas that make up the field. The main alterations identified in the evolution of GC were: it acquired a better defined identity, with more participation of academy and increased scope; was progressively framed in sustainability; has been aspiring to a holistic frame and to a change on the nature of the innovation for its implementation, from incremental to transformative. The analysis suggests that for supporting expansion and consolidation of GC the following aspects deserve attention: full validation of chemical greenness by metrics; better characterization of the frontiers of GC research areas/themes; increased integration between academy and industry; and penetration in chemistry curricula. Its basic philosophy being the practice of a chemistry more focused on the environment preservation, GC means a new stage in nature and in the history of Chemistry. (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)

In this article, we formally define and investigate the computational complexity of the definability problem for open first-order formulas with equality. Given a logic $\boldsymbol{\mathcal{L}}$, the $\boldsymbol{\mathcal{L}}$-definability problem for finite structures takes as an input a finite structure $\boldsymbol{A}$ and a target relation $T$ over the domain of $\boldsymbol{A}$ and determines whether there is a formula of $\boldsymbol{\mathcal{L}}$ whose interpretation in $\boldsymbol{A}$ coincides with $T$. We show that the complexity of this problem for open first-order formulas is coNP-complete. We also (...) investigate the parametric complexity of the problem and prove that if the size and the arity of the target relation $T$ are taken as parameters, then open definability is $\textrm{coW}[1]$-complete for every vocabulary $\tau $ with at least one, at least binary, relation.

The purpose of the paper is to present a logical framework that allow to formalize a kind of prima facie duties, defeasible conditional duties, indefeasible conditional duties and actual (indefeasible) duties, as well as to show their logical interconnections.

Resumen: Este artículo sostiene que la regla en el mundo social es el cambio, en todas las escalas de tiempo, sin ciclos ni periodicidades. Por consiguiente, el tema que emerge inmediatamente es la irregularidad del mundo. Si esto es cierto, deben ser posibles unas ciencias sociales irregulares. El mejor antecedente para una idea semejante se encuentra en la comprensión del propio Mandelbrot acerca de los fractales y multifractales. Las ciencias sociales tratan radicalmente, de fenómenos irrepetibles, singulares. Estos han sido llamados (...) como eventos raros. De esta suerte, una nueva epistemología emerge y es posible. Al final se muestra que existen nexos fuertes entre las ciencias sociales con la biología y la ecología. Pero en ese punto, el texto termina abierto.: This paper claims that change is the rule in the social world, in all scales of time, without cycles or periodic dynamics. Hereafter, the topic that immediately arises is the irregularity of the world. If this is true, then irregular social sciences are to be possible. The best antecedent of such an idea is to be found in Mandelbrot’s own understanding of fractals and multifractals. Thus, the social sciences radically deal with phenomena that are in no way repeated, for they are singular. Such events have been called as rare events. In thus tenure, a brand-new epistemology arises and is possible. At the end, some connections between the social sciences and biology and ecology are depicted. That, however, is where this text ends and remains open. (shrink)

No cartesianismo contemporâneo, devido à retomada da teoria da livre criação das verdades eternas, alguns intérpretes trazem ao debate internacional um interessante viés interpretativo do pensamento de Descartes. Segundo eles, ao apresentar a indiferença da vontade como atributo de Deus, Descartes instaura uma concepção totalmente perigosa, da qual derivam a incompatibilidade entre a indiferença divina e o sistema cartesiano, deflagrando, enfim, um irracionalismo radical.

Las nociones de "uno" y de "múltiple" han sido, históricamente, objeto de tratamiento, a la vez, filosófico y teológico. En el contexto de la filosofía islámica oriental, y en el marco de su vertiente más específicamente neoplatónica, el "Príncipe de los Teósofos", Sadrá Sirázi (ob. 1050/1640), estudia ambas desde una perspectiva ontológica y distanciándose del enfoque consignado al respecto por los filósofos peripatéticos del Islam. Adaptando y continuando, de un lado, la gnosis de 1km aI-'Arabi, y, de otro, la sabiduria (...) iluminativa de Sohravardi, MollA Sadrá discute la distinción aviceniana entre un Ser Necesario y una multiplicidad de seres posibles, así como la posibilidad de considerar accidental la realidad de la existencia. Basado en la eoimplicación de tres conceptos fundamentales: i~álat al-wu9ñd (prioridad del ser), i,vahdat al-wu9i2d (unidad del ser) y tagkik (diferenciación y gradación intensiva del ser), el univocismo monadológico de 5adrá puede, por otra parte, permitirnos reevaluar ciertas cuestiones filosóficas que pugnan por ser examinadas hoy a una nueva luz.

¿Cuál es la distancia mínima entre autor y obra? ¿Pueden unos números sucesivos trazados en un lienzo convertirse en el testimonio de una existencia? Estas y otras muchas preguntas emergen cuando se analizan las obras del pintor polaco Roman Opalka. Su proyecto OPALKA 1965/1-∞ constituye un hito en el arte contemporáneo por su intención de explorar la representabilidad de la duración del tiempo y del ser en su carácter existencial en relación a la muerte. La extrema longitud del proyecto, desarrollado (...) durante más de cuatro décadas, así como su aparente precariedad formal encierran un mensaje pleno de potencia que cuestiona la relación que tenemos con nuestra propia vida.

Philosophical action theory seems to be in pretty good shape. The same may not be true for the study of human action in economics. Famous is the rant that the study of human action in economics gives reason to tremble for the reputation of the subject. But how does this come about? Since economic action is about action, the broader study must surely have a strong impact on the more specific field. The paper sets out, from the ground up, how (...) an essential concept in economic theory–the concept of competition–can fundamentally benefit from insights derived exclusively from analytical action theory broadly conceived. In doing so, the paper delivers on an old Austrian promise: it is sometimes claimed that Austrian economists understand competition better than most economists. This may be a bold claim, since Austrian economists have neither traced the understanding of subjectivity to its very origin (the theory of intentionality), nor have they traced their sympathy for methodological individualism in relation to market processes to its very ground (the theory of (human) action). This paper aims to fill this gap. Moreover, by grounding an Austrian view of competition in analytic action theory, it succeeds in avoiding the serious problems of the dominant equilibrium approach. By explaining competition as rivalry, the paper draws on the philosophy and logic of human action to bring the (economic) agent back into play. In this way, a case is made for an integrated view of Austrian theory as an amalgam of Austrian economics and analytic action theory. (shrink)

Despite increasing attention to the sensors, drones, robots, and apps permeating agri-food systems, little attention has been paid to social media, perhaps the most ubiquitous digital technology in rural areas globally. This article draws on analysis of farming groups on Myanmar Facebook to posit social media as appropriated agritech: a generic technology incorporated into existing circuits of economic and social exchange that becomes a site of agrarian innovation. Through analysis of an original archive of popular posts collected from Myanmar-language Facebook (...) pages and groups related to agriculture, I explore the ways that farmers, traders, agronomists and agricultural companies use social media to further agrarian commerce and knowledge. These activities evidence that farmers use Facebook not only to exchange market or planting information, but also to interact in ways structured by existing social, political and economic relations. More broadly, my analysis builds on insights from STS and postcolonial computing to disrupt assumptions about the totalizing power of digital technologies and affirm the relevance of social media to agriculture, while inviting new research into the surprising, ambiguous relationships between small farmers and big tech.

A fauna sul-americana evolveu durante dezenas de milhões de anos em isolamento dos outros continentes. Isso conferiu-lhe um carácter muito particular, comprovado pelo enorme número de táxones endémicos da divisão biogeográfica em que se inclue o sub-continente – Região Neotropical.Quando os descobridores e colonizadores abordaram e foram penetrando no Brasil, no século XVI e seguintes, deparou-se-lhes uma fauna – abundante na época –, diversificada e estranha ao seu conhecimento da fauna europeia, quando muito também de algumas espécies asiáticas e africanas. (...) As tendências reveladas pelos ‘colonizadores-naturalistas’ na descrição dessa fauna foram diferentes. Uns denominaram-na como se de espécies europeias ou africanas se tratasse. Outros reconheceram a sua originalidade, adoptando a nomenclatura etnobiológica dos Índios, a qual reproduziram em sons da língua portuguesa. Pêro de Magalhães Gândavo, o primeiro português a produzir obra impressa em que se descreve a fauna brasílica, seguiu ambas as vias, conforme os casos. É do seu relato, publicado em 1576, que se apresentam e comentam alguns excertos neste artigo.South American biodiversity evolved for tens of million years in isolation. A most special composition of its fauna and flora has been the result of such an isolation period, the number of endemic taxa being very large. Biogeographers soon recognized the singularity of South America, including this sub-continent in a biogeographical division of the highest rank - the Neotropical Region. When Portuguese discoverers and explorers, from the 16th century on, passed into Brazil, they found a diversified and exotic fauna quite different from the European or African ones that they eventually knew. Some of them, namely jesuits and other educated people, described the most common or conspicuous species, indicating the main edible or dangerous properties of each one. Ethnobiological nomenclature or the common names of the closer European or African species have been applied by those ‘naturalists’. The first of them recording his observations and speculations on a printed book was Pêro de Magalhães Gândavo, who lived in Brazil for a few years before 1561. Comments on his interesting book, entitled História da Província de Santa Cruz, are presented in this paper. (shrink)
