Este estudio exploró los discursos y sus procesos de subjetivación que realizan los interventores psicosociales de infancia y adolescencia que participan en dispositivos del Estado de Chile. A partir de la metodología cualitativa, entrevistas semiestructuradas y análisis crítico del discurso. Los resultados muestran significados de la infancia y adolescencia asociados al cuidado, al peligro y a un sujeto de derechos con agencia. Este último, resiste a la violencia institucional mediante el apoyo mutuo entre pares y con los interventores. Esta investigación (...) subraya la importancia de intervenciones psicosociales participativas con una infancia y adolescencia como agentes sociales y políticos. (shrink)

Phantasmagoria explores ideas of spirit and soul since the Enlightenment; it traces metaphors that have traditionally conveyed the presence of immaterial forces, and reveals how such pagan and Christian imagery about ethereal beings are embedded in a logic of the imagination, clothing spirits in the languages of air, clouds, light and shadow, glass, and ether itself. Moving from Wax to Film, the book also discusses key questions of imagination and cognition, and probes the perceived distinctions between fantasy and deception; it (...) uncovers a host of spirit forms--angels, ghosts, fairies, revenants, and zombies--that are still actively present in contemporary culture. It reveals how their transformations over time illuminate changing ideas about the self. Phantasmagoria also tells the accompanying story about the means used to communicate such ideas, and relates how the new technologies of the Victorian era were applied to figuring the invisible and the impalpable, and how magic lanterns (the phantasmagoria shows themselves), radio, photography and then moving pictures spread ideas about spirit forces. As the story unfolds, the book features the many eminent men and women--scientists and philosophers--who in the Society of Psychical Research applied their considerable energies to the question of other worlds and other states of mind: they staged trance seances in which mediums produced spirit phenomena, including ectoplasm. The book shows how this often embarrassing story connects with some of the important scientific discoveries of a fertile age, in psychology and physics. Over a sequence of twenty-eight chapters, with over thirty illustrations in color and black and white, Phantasmagoria thus tells an unexpected and often uncomfortable story about shifts in thought about consciousness and the individual person, from the first public waxworks portraits at the end of the eighteenth century to stories of hauntings, possession, and loss of self as in the case of the zombie, a popular figure of soulessness, in modern times.

Our brains readily decode facial movements and changes in social attention, reflected in earlier and larger N170 event-related potentials (ERPs) to viewing gaze aversions vs. direct gaze in real faces (Puce et al. 2000). In contrast, gaze aversions in line-drawn faces do not produce these N170 differences (Rossi et al., 2014), suggesting that physical stimulus properties or experimental context may drive these effects. Here we investigated the role of stimulus-induced context on neurophysiological responses to dynamic gaze. Sixteen healthy adults viewed (...) line-drawn and real faces, with dynamic eye aversion and direct gaze transitions, and control stimuli (scrambled arrays and checkerboards) while continuous electroencephalographic (EEG) activity was recorded. EEG data from 2 temporo-occipital clusters of 9 electrodes in each hemisphere where N170 activity is known to be maximal were selected for analysis. N170 peak amplitude and latency, and temporal dynamics from event-related spectral perturbations (ERSPs) were measured in 16 healthy subjects. Real faces generated larger N170s for averted vs. direct gaze motion, however, N170s to real and direct gaze were as large as those to respective controls. N170 amplitude did not differ across line-drawn gaze changes. Overall, bilateral mean gamma power changes for faces relative to control stimuli occurred between 150-350 ms, potentially reflecting signal detection of facial motion. Our data indicate that experimental context does not drive N170 differences to viewed gaze changes. Low-level stimulus properties, such as the high sclera/iris contrast change in real eyes likely drive the N170 changes to viewed aversive movements. (shrink)

RESUMO Neste artigo, propomos estratégias de captação de regiões polêmicas em corpus produzido a partir de publicações do Twitter, partindo de quadro teórico que enfatiza a perspectiva dialógica. Com base nessas estratégias, fornecemos entradas para a análise da materialidade oriunda do universo tecnodiscursivo em circulação em ambientes digitais. Em razão da produção do corpus da investigação, avançamos na compreensão de traços que compõem imagens discursivas em torno de Diego Maradona em circulação no Twitter por ocasião de seu falecimento. Para tanto, (...) explicitamos e problematizamos técnicas de captação e produção de um corpus digital de pesquisa, através da delimitação de um espaço discursivo no Twitter que circundou a morte de Maradona. Os resultados obtidos se dirigem tanto às condições de utilização dessas plataformas por analistas do discurso, quanto à cartografia das regiões do dizer que se configuram nesse espaço e dos embates que nelas ganham consistência. ABSTRACT In this article, we propose strategies for capturing polemical regions in a corpus of posts from Twitter, setting out from a theoretical framework that emphasises a dialogic perspective. Based on these strategies, we provide entry points for analysing the materiality of the techno-discursive universe that circulates in digital environments. By producing this research corpus, we acquired a clearer understanding of elements that compose discursive images surrounding Diego Maradona in circulation on Twitter following the player’s death. Towards this aim, we formulated and critically considered techniques for extracting and producing a digital research corpus by delimiting a discursive space on Twitter surrounding Maradona’s death. The results obtained pertain to the conditions for use of these platforms by discourse analysts, the cartography of the regions configured in this space and the clashes that become consolidated within them.

El artículo analiza la noción de régimen de veridicción como posible elemento de análisis político, tomando como foco los planteamientos de Foucault en el curso de 1979 Nacimiento de la biopolítica. En este curso, dicha noción es explicada por primera vez y aunque el tema de la veridicción tiene un importante protagonismo en los trabajos posteriores de Foucault, este curso tiene una especial relevancia pues relaciona la operación de veridicción con unas tecnologías políticas de gobierno, como son las artes liberales (...) de gobierno e incluso sus modificaciones en el contexto del neoliberalismo.

Plato’s Protagoras plays off the genre of Greek comedy in its expression of its philosophical meaning. This dialogue at points invites us to re-envision Socrates against the backdrop of Aristophanes’ criticisms of Socrates and the sophists. The Protagoras follows some of the conventions of Greek comedy but interrupts its form with moments of lengthier rational discussion absent in Greek comedy. The dialogue’s logos and antilogos lead to aporia, but this aporia shows a limit to reason that recognizes human incompleteness without (...) leading to misology. In contrast to performed drama, the written form of the dialogue both engages its audience’s emotions while allowing the reader to return to the text and to continue their rational assessment of the arguments.

Resuelta evidente la desigualdad que ha develado la crisis sanitaria a nivel global. Sin embargo, no se trata de una fotografía actual, sino que ha puesto de manifiesto las falencias estructurales del sistema económico político global y, con ello, los devastadores efectos sobre el ser humano en todas sus dimensiones. Las consecuencias de la pandemia no son homogéneas dentro de una misma sociedad. Existen sectores que se han vuelto más ricos y otros más pobres. Las distancias en salud, bienestar y (...) dignidad de los individuos han aumentado y estamos ante una crisis de que esta injusticia se siga calcificando. El ser humano no sólo tiene que sobrevivir sino lograr la fundamental biopsicosocial realización tanto individual como colectiva. Por lo tanto, es imperativo, recuperar al Otro, al necesitado, dentro del discurso y, sobre todo, en la acción política, mirando al Otro como un fin en sí mismo, y no como un medio. Este es el origen y debe volver a ser la finalidad primordial de la política interna y externa de cada gobierno. Para ello, la reflexión filosófica nos proporciona nuevas perspectivas para reestructurar la realidad, cambiando, y mejorando, las escalas de valores y nuestro modo de actuar. La postpandemia nos plantea un único objetivo, el restaurar y reactivar las verdaderas relaciones intersubjetivas, rehumanizando al hombre, es decir, volviendo a la raíz de la esencia de toda sociedad, que no es otra que el ser humano mismo, como un fin en sí mismo. No se podrá lograr de manera inmediata, por lo tanto es fundamental recanalizar todas las herramientas e instituciones políticas hacia y para el bienestar del hombre, sin devastar su entorno, donde la reflexión filosófica es primordial para construir un nuevo mundo.

The continued development of General Circulation Models (GCMs) towards increasing resolution and complexity is a predominantly chosen strategy to advance climate science, resulting in channelling of research and funding to meet this aspiration. Yet many other modelling strategies have also been developed and can be used to understand past and present climates, to project future climates and ultimately to support decision-making. We argue that a plurality of climate modelling strategies and an equitable distribution of funding among them would be an (...) improvement on the current predominant strategy for informing policy making. To support our claim, we use a philosophy of science approach to compare increasing resolution and complexity of General Circulation Models with three alternate examples: the use of machine learning techniques, the physical climate storyline approach, and Earth System Models of Intermediate Complexity. We show that each of these strategies prioritises a particular set of methodological aims, among which are empirical agreement, realism, comprehensiveness, diversity of process representations, inclusion of the human dimension, reduction of computational expense, and intelligibility. Thus, each strategy may provide adequate information to support different specific kinds of research and decision questions. We conclude that, because climate decision-making consists of different kinds of questions, many modelling strategies are all potentially useful, and can be used in a complementary way. (shrink)

El artículo trata sobre las visiones de la historia comprometidas en la gubernamentalidad neoliberal, pragmática y presentista, y sus relaciones con el fascismo utópico, futurista y destinal. Para iniciar este debate usa como punto de arranque los análisis y discusiones biopolíticas; al mismo tiempo se pregunta sobre las condiciones de una visión histórica de la filosofía que pueda servir de alternativa a las filosofías del origen o del destino sin diluirse en el debate sobre las épocas históricas.

La celebración de fiestas en honor a los santos patronos de las comunidades andinas es una de las manifestaciones de religiosidad más extendidas desde Colonia. Másallá de entenderla como una manifestación en continuidad directa con las prácticas cúlticas del Tawantinsuyo o la ritualidad católica española, consideramos que esta festividad es un fenómeno emergente que debe ser analizado en su especificidad. El objetivo de este artículo es analizar la figura del santo y su eficacia simbólico-ritual en la fiesta patronal andina desarrollada (...) durante el periodo colonial (XVI-XVII). A partir del análisis de una serie de crónicas coloniales, intentaremos mostrar que las especificidades rituales de la fiesta y de la operación del santo como símbolo icónico dominante permiten comprender su eficacia simbólica, así como también la co-existencia de diversas interpretaciones y escenificaciones rituales que darían cuenta de la agencialidad ritual de la comunidad. The celebration of festivities in honor of the patron saints of the Andean communities is one of the most widespread manifestations of religiosity from the Colony. Beyond understood as a manifestation in direct continuity with the cultic practices of the Catholic ritual Tawantinsuyo or Spanish, we believe that this festival is an emerging phenomenon that must be analyzed in its specificity. The aim of this paper is to analyze the figure of the saint and their efficacy in symbolic ritual Andean fiesta developed during the colonial period (XVI-XVII). From the analysis of a series of colonial chronicles, try to show that the specific rituals of celebration and operation saint as provide insight dominant iconic symbol symbolic effectiveness, as well as the co-existence of different interpretations and stagings rituals give account of agency community ritual.

En el actual clima de acechantes cuestionamientos sobre la identidad regional, suelen tener recepción versiones cuando no ahistóricas o esencialistas, deterministas o simplistas que lo que hacen es reducir la noción arrinconándola en categorías que poco o nada aportan a la autocomprensión de nuestros pueblos. De modo que resulta pertinente volver sobre una mirada en que la identidad debe ser concebida como un fenómeno social complejo, conflictuado y relacional en constante reconstrucción. Nuestra América, en este sentido, sigue siendo un texto (...) fundamental porque no solo permite comprender la idea de nación moderna que propone el cubano, sino también el modo de construirla. Un proyecto sociocultural inconcluso y que lo será solo si acepta la diferencia como constructo base de nuestra heterogénea realidad. In the current climate of pressing questions about regional identity, there tends to be, if not ahistorical or essentialist versions, at least determinist or simplistic ones that only reduce the notion cornering it into categories that contribute little or nothing to the understanding of our peoples. Therefore, it is pertinent to turn our eyes toward a vision of identity that should be conceived as a complex, conflictive, and relational social phenomena in constant reconstruction. “Nuestra América”, in this sense, continues to be a fundamental text since it not only permits us to understand the idea of the modern nation proposed by the Cuban, but also the way in which it must be build. This is an inconclusive sociocultural project which will only be finished if difference is accepted as a basic building block of our heterogenous reality. (shrink)

El presente artículo apunta a discutir cómo los actos cívicos o los monumentos actuaron en los albores del siglo XX como mecanismos de articulación dinámica de la “chilenización” en el desierto tarapaqueño, particularmente en el puerto de Iquique. Se reflexiona desde una perspectiva sociohistórica en torno a las fiestas públicas como rituales simbólicos donde se materializa la integración y/o pertenencia a la comunidad nacional; eventos cívicos que no dejaron de ser menos persuasivos como otras formas mas “violentas” de implantar y (...) promover el sentido de la Nación en los nuevos territorios anexados al Estado chileno.

Este artículo aborda el concepto de lo político de Carl Schmitt y la teoría populista de Ernesto Laclau. Se ofrece, primero, una crítica de la literatura sobre la supuesta recepción del pensamiento de Schmitt en Laclau, en relación a sus nociones de antagonismo, representación, unanimidad, e identificación. Luego se reconstruyen y comparan los argumentos de los dos autores sobre el enemigo, la referencia al pueblo como sujeto político y el carácter existencial de lo político. Sin pretensión de elaborar un análisis (...) conceptual exhaustivo para no exceder el espacio aquí disponible, se señala que a lo largo de su trayectoria Laclau ignoró a Schmitt (a excepción de un artículo sobre la guerra) y que, si bien Schmitt no fue una influencia intelectual en Laclau, hay algunas similitudes en sus modelos teóricos.

Pregnancy presents some interesting challenges for the philosophy of embodied cognition. Mother and fetus are generally considered to be passive during pregnancy, both individually and in their relation. In this paper, we use the enactive operational concepts of autonomy, agency, individuation, and participation to examine the relation between mother and fetus in utero. Based on biological, physiological, and phenomenological research, we explore the emergence of agentive capacities in embryo and fetus, as well as how maternal agency changes as pregnancy advances. (...) We show that qualitatively different kinds of agency have their beginnings already in utero, and to what extent fetal and maternal movement modulate affectivity and individuation in pregnancy. We thus propose that mother and fetus are both agents who participate in pregnancy. Pregnancy then emerges as a relational developmental organization that anchors and holds its developing participants. We end the paper with reflections on ethical implications of this proposal, and suggestions for future research. (shrink)

This paper develops a largely neglected parallel between prudence and population ethics. Prudence is generally understood to be concerned with the balancing of well-being over time. How, precisely, well-being ought to be balanced over time, however, is a fervently debated question. I argue that developing a standard guiding such evaluations is exceedingly challenging. This is due to an often overlooked fact about prudence, namely that it shares a structural similarity with population ethics: In both contexts, we assess the comparative value (...) of populations of personstages/people, which may vary in number and level of well-being. Based on this analogy, I show that the development of an adequate theory of prudence runs into very similar impossibility results as obtain in population ethics. In particular, I prove that Arrhenius’ fifth impossibility theorem can be applied to prudence. I develop and compare four possible answers to this challenge. First, I discuss the possibility of accepting the very repugnant conclusion intrapersonally. Second, I present and further develop Donald Bruckner’s Minimax Regret approach, which gives up Transitivity. Third, I apply Jacob Nebel’s Lexical Threshold View to prudence and critically evaluate it. Lastly, I introduce what I call the Negative Lexicality View, which is based on Lexical Threshold View but overcomes some of its problems. (shrink)

Certains des moments qui ont marqué la liesse de la révolte de 2019 et le rejet encore incompréhensible de la proposition constitutionnelle, qui reprenait une grande partie des revendications de la rue, sont déroulés sous forme de flashs. Passé, présent et futur se confondent dans ce récit et émergent d’une photographie autour de laquelle s’articulent ces mots : un homme en costume-cravate, un policier, une foule en révolte, un silence spectral.

Osip Mandel'štam belongs among the greatest Russian poets of the twentieth century. During the thirties, when he led a tragic existence and felt a premonition of his inevitable violent death, Mandel'štam saw in Dante not only the greatest poet, but also his own superior teacher, and his poems of that period contain a tormented meditation on the masterpiece of Dante's genius -- the "Divine Comedy". Epic poetry of Dante, Homer, Virgil and others was possible because the inner world of each (...) poet was essentially at one with the ethos of the society in which he lived. Mandel'štam's inner world was Judaeo-Christian, European, and rooted in classical and neo-Platonic philosophy, but his outer world, consisting of a new Marxist or pseudo-Marxist system, was totally at odds with it. Thus Mandel'štam could not embody the epic impulse of the society he opposed. He was left with the tormented lyric impulse. The fundamental conflict between Mandel'štam as a lyric poet and the society in which he had to live and work accounts for the fact that his vision of Stalinist society in a number of respects remarkably corresponds to Dante's vision of a perverted divine order in the Inferno.

In Mandel'štam's writing, artistic creativity is described as based on the indispensable yet contradictory modes of compliance and deviation. The artist, by his artistic nature, must be an "obedient disciple" to the tradition that inspires him, and, at the same time, a "violator" who renders what inspires him in an individual form. Thus, art implies iterability through novelty. In the totalitarian state, this double nature of art acquires a sinister context and brings the artist to an unavoidable conflict with the (...) state. He has a choice between a servile compliance with the state's command and artistic independence. If the artist complies, he loses his ingenuity; if, on the other hand, he has the courage to break away from the established order, his fate is martyrdom. The criteria of truth and falsehood, the issue of loyalty, of compromise and collaboration or resistance become most relevant. Such words as "outcast" or "non-contemporary" acquire the meaning of "non-collaborationist" or "enemy of the people". In the totalitarian state a genuine artist is viewed as a "law-breaker", and his art leads him to "crime". The notions of compliance and deviation cease being merely aesthetic terms and assume in Mandel'štam's poetry complex, subtle and tragic overtones. (shrink)

El presente trabajo reflexiona sobre la estructura dual del signo dada por la conjunción del significado, aquello que es objeto de comprensión, y el significante, el medio material que permite expresar lo comprendido. Sin embargo, considerando la vida de emociones despertadas por estímulos cargados de valoración estética, en particular el movimiento corporal y la música, la estabilidad y armonía de di-cha estructura dual son puestas en cuestión. En dicho contexto de inestabilidad, la creatividad y la transformación se manifiestan como condiciones (...) esenciales y necesarias para la marcha del lenguaje. (shrink)

At Universitat Politècnica de València, Meridies, an internship programme that places engineering students in countries of Latin America, is one of the few opportunities the students have to explore the implications of being a professional in society in a different cultural and social context. This programme was analyzed using the capabilities approach as a frame of reference for examining the effects of the programme on eight student participants. The eight pro-public-good capabilities proposed by Melanie Walker were investigated through semi-structured interviews. (...) The internship is an environment in which students can put into practice the knowledge they have acquired in undergraduate studies and to find practical relevance in what they studied. Occasionally, this also entails a critical questioning of what they have learned, a greater awareness of the limits of the contents of their studies and of the way things were taught, and interest in less explored issues that are closely linked to social justice. However, tensions can arise between the pro-public-good oriented perspectives of this programme, and a more instrumental vision. One way to overcome these tensions is to foster consideration of reflexivity, that is, the dynamic relationship between technology and society. To do so, the programme must create space before and during the internship, and upon the return of the students, to discuss and collectively reflect upon their lived experience. Additionally, it ought to engage supervisors in this educational journey, both at the university and in the host institutions, and also involve socially committed organisations in this task.

Este trabajo aborda algunos aspectos de la dimensión social y política del museo en la actualidad, a partir de la articulación de distintas perspectivas vinculadas con las políticas de los bienes comunes, la sociomuseología y la museología participativa. Este cruce teórico permitió diseñar un escenario o un subescenario -según qué lectura se pondere- político-museológico en el que, consideramos, existe una apuesta por una diferenciación de los modelos tradicionales.

Recent scientific studies suggest that the destabilisation of the earth's climate and biodiversity loss are not separate, but interdependent phenomena. In this context, some have proposed the creation of a ‘Global Safety Net’ of ecoregions that should be preserved to stop further biodiversity loss, preventing at the same time the growth of CO2 emissions produced by deforestation and allowing natural carbon removal. In this article, I suggest that a first step to achieve this might be to replace permanent sovereignty over (...) natural resources in these areas with permanent guardianship. I propose to take some inspiration from a model that has already been implemented over an entire continent with a fair degree of success. In 1959, the Antarctic Treaty froze the sovereign claims of seven countries over Antarctica. However, these countries plus 47 others today have been remarkably successful at jointly preserving the continent for peace, science, and the protection of the environment, especially since the signature of the Environmental Protocol in 1991. After outlining some principles that could give form to a Global Environmental Protocol for Ecoregions, I address a series of objections and offer some concluding remarks. (shrink)

Managers in ethnic businesses are confronted with ethical dilemmas when taking action based on ethnic ties; and often as a result, they increase the already vulnerable positions of these businesses and their stakeholders. Many of these dilemmas concern the capital that is generated through variations in the use of ethnic stakeholder social ties. The purpose of this paper is to suggest a stakeholder-based model of social capital formation, mediated by various forms of ethnic ties, to explore the duality of ethnicity: (...) it can aid and hinder an ethnic business. Drawing upon the social capital/economic development, stakeholder salience, ethnic businesses literatures, and on social identity theory, we develop a cyclical model of relationships among ethnic business stakeholder attributes and social capital, as mediated by three-way Simmelian bonding and bridging ties, which then, in turn, affects the ethnic stakeholder attributes. We argue that the development of bridging yet strong ties through this cyclical process is relevant for the improvement of the positions of ethnic businesses in terms of both economic success and social responsibility. Specifically, we suggest that, given the duality of ethnicity in business, managers can prioritize stakeholder relationships based upon how these stakeholder ties affect social capital. (shrink)

We show that in the Maxwell–Lorentz theory of classical electrodynamics most initial values for fields and particles lead to an ill-defined dynamics, as they exhibit singularities or discontinuities along light-cones. This phenomenon suggests that the Maxwell equations and the Lorentz force law ought rather to be read as a system of delay differential equations, that is, differential equations that relate a function and its derivatives at different times. This mathematical reformulation, however, leads to physical and philosophical consequences for the ontological (...) status of the electromagnetic field. In particular, fields cannot be taken as independent degrees of freedom, which suggests that one should not add them to the ontology. (shrink)
