Possibilities of scientific research about radio are explored, radio as mass media and contemporary language, within of an overview of radio studies. Two analytical traditions about radio are sketched, suggestioning that anthropology of radio should deepen early observations and reflections of Ru..

Conviene subrayar en la época de la ciencia, cuando las prácticas más aberrantes y las especulaciones más desaforadas compiten por arrogarse el título de ciencias, que la filosofía no es una ciencia, ni necesita serlo para ejercer sus funciones críticas. No obstante, mantiene una relación íntima y constante con las ciencias desde sus orígenes hasta nuestros días (relación histórica), utiliza el mismo instrumento metodológico, la razón crítica (relación metódica) y recorre el mismo ámbito de la experiencia cognoscitiva humana (relación sistemática). (...) En ese sentido, la filosofía no se arredra ante el discurso postmoderno de la deslegitimación —Lyotard, Baudrillard, Vattimo, etc.—. Aunque las soluciones filosóficas son legitimadoras, no se reducen a mera ideología, ni tecnocrática ni progresista. (shrink)

Estas líneas están escritas como homenaje a Ricardo Sánchez Ortiz de Urbina, con todo el cariño y con la esperanza de ser acogido con la benevolencia que demanda el ensayo. En todo caso, nunca podré dejar de agradecer a nuestro maestro que me permitiera salir sin brusquedad del encierro al que me había conducido el sujeto gnoseológico, el sujeto de la ciencia, siempre omnipresente en toda investigación. Siguiendo la estela de la matriz fenomenológica configurada por Urbina, entreví en el (...) nivel superior ―el nivel de máxima ambigüedad―, y mediante trasposiciones sucesivas, el origen humano de los celos, que desbordan el simple comportamiento o el mero afecto. Los celos como fondo siempre desbordante en el proceso que nunca concluye de fijación de la identidad humana. Un camino que habían recorrido, con los medios de que disponían, los escritores del Barroco español en el contexto de los conversos hispanos y Miguel de Cervantes como centro. (shrink)

En un artículo anterior, titulado «Del Diálogo del Guerrero al Diálogo del Hogar: para una fenomenología de los celos» y en homenaje a Ricardo Sánchez Ortiz de Urbina, concluía que el amor y los celos forman el arranque mismo de la condición humana en su dimensión del exceso: no es la dualidad discreta Amor/Odio la expresión de la base y el fundamento de los afectos, sino la dualidad continua Amor/Celos. Las preguntas surgen de suyo: ¿con qué concepto quedaría vinculado (...) por continuidad y exceso el odio? ¿Y cuál es la posición que le corresponde al odio respecto del amor? A partir de un comentario de Maimónides —en el que vincula la enemistad con el odio y del que sólo el conocimiento de la verdad puede alejarnos—, argumentaré que el odio es generado por la crítica, por el saber crítico, que destruye la verdad absoluta. Y propondré un cuadro semiótico-topológico explicativo con ejemplos literarios e históricos. (shrink)

This work, in English "Struggle for power, organic crisis and judicial independence", has its origin in research academics of the IAEN carried out to provide expert advise to the Inter American Court of Human Rights in the case Quintana and others (Supreme Court of Justice) vs the State of Ecuador. The research is about the nature of the evolution of the ecuadorian state, the dynamics of its institutions, its players, parties, laws, its factors of instability, the way rights have (...) been deployed since the return to democracy in 1979, those who have benefited from neoliberal democracy and those who have paid the costs, and where in all this was the Supreme Court of Justice. The Introduction takes a look at this origin of the work and its intellectual import, provides a brief characterization of the Inter American Sistem of Human Rights Protection, how the Quintana Case fits within it, and an overview of the chapters and their logic. The first chapter analyzes the institutional and sociological factors that have contributed to Ecuador's historically unstable state, based primarily in an antagonistic struggle for power between the Executive and Legislative branches. The second chapter analyzes the economic and political factors that provoked an organic crisis, or crisis of hegemony, between 1997 and 2007 in Ecuador. The third chapter analyzes the evolution of the way in which judges are selected in Europe, the outcomes they have generated, and how they compare with the ecuadorian systems of judge selection in terms of securing judicial independence. The fourth chapter develops a theory of judicial independence in democracy and analyzes how Ecuador measures up to that standard, from when it became a neoliberal minimal democracy in 1981, to when it became a neoliberal false democracy as a consequence of instalation of a system evidently lacking in the people's support under the guise of the 1998 Constitution and its system of judge selection, and the new democratic horizons set by the 2008 Constitution, and the judicial system that springs from it.

El autor pasa revista a la concepción de la historia como disciplina que exhibe el filósofo Fernando Miguel Pérez Herranz. El motivo de este concienzudo análisis es la publicación en marcha del magno proyecto Más allá de imperios y naciones (4 vols.) iniciado en 2023 y que ya cuenta con dos tomos en el mercado: Rutas, fronteras y complejidad y Singularidad imperial: del Mediterráneo al Atlántico. Esta concepción del estatuto gnoseológico de la historia tiene en Lindos y tornadizos (2016) (...) y en Ambiguus proetus (2019) dos momentos esenciales que dibujan el paso Herranz a su perspectiva (la morfología filosófica) en el debate entre Gustavo Bueno y Ricardo Sánchez Ortiz de Urbina a cuenta del sujeto trascendental. En tal contexto cobran relevancia las hipercategorías formuladas por Pérez Herranz y cuyo estatuto resulta problemático. (shrink)

Trust in vaccination is eroding, and attitudes about vaccination have become more polarized. This is an observational study of Twitter analyzing the impact that COVID-19 had on vaccine discourse. We identify the actors, the language they use, how their language changed, and what can explain this change. First, we find that authors cluster into several large, interpretable groups, and that the discourse was greatly affected by American partisan politics. Over the course of our study, both Republicans and Democrats entered the (...) vaccine conversation in large numbers, forming coalitions with Antivaxxers and public health organizations, respectively. After the pandemic was officially declared, the interactions between these groups increased. Second, we show that the moral and non-moral language used by the various communities converged in interesting and informative ways. Finally, vector autoregression analysis indicates that differential responses to public health measures are likely part of what drove this convergence. Taken together, our results suggest that polarization around vaccination discourse in the context of COVID-19 was ultimately driven by a trust-first dynamic of political engagement. (shrink)

Epidemiological models directly shape policy responses to public health crises. We argue that they also play a less obvious but important role in solving certain coordination problems and social dilemmas that arise during pandemics. This role is both ethically and epistemically valuable. However, it also gives rise to an underappreciated dilemma, as the features that make models good at solving coordination problems are often at odds with the features that make for a good scientific model. We examine and develop this (...) dilemma in the context of the COVID-19 pandemic, and suggest extensions to other domains. (shrink)

This paper addresses a neglected question in republican political philosophy: what are the conditions for a set of arguments to be considered republican? While republicanism traditionally confers a fundamental role to the democratic ideal of participation in decision-making, recent contributions argue that freedom could be promoted by facilitating exit where possible. The strong version of the latter argument states that when exit is possible, it constitutes the most important contribution to republican freedom, and it preserves the goal of isolating individual (...) choices, i.e. it precludes collective decision-making from interfering with them, and so it intends to limit the scope of public concern considered legitimate. I examine this argument to discuss the boundaries and varieties of republicanism: (i) the boundaries establish that an argument should be couched and substantively articulated in distinctively republican terms; (ii) the strong version of the exit argument does not fall within the boundaries because it is in tension with core republican commitments to self-government and civic virtues; (iii) once we abide by the boundaries we may encounter a diversity of proposals differing on the more concrete level of institutional design and empirical assumptions – these are the varieties of republicanism.

Todo el curso gravita sobre la función reproductiva de la trompa. La trompa, en fin de cuentas, es un oviducto. Ya bastante habrán dicho de todo ello Michel Idoate y Fernando de la Fuente. Yo lo que quiero hacer en mi charla es llamar la atención sobre los aspectos éticos de unos pocos hechos básicos: que, de ordinario, la fecundación tiene lugar en la ampolla tubárica y que aquí y en el istmo transcurren las primeras horas y los primeros días (...) del desarrollo embrionario. Estos hechos, tan conocidos, tienen implicaciones ético-médicas muy importantes. La principal de ellas, se refiere a quien sea el embrión humano que se engendra en la trompa y en ella habita cuatro o cinco días. Pero, no menos importante, es la que se refiere a cuáles son las relaciones éticas que han de establecerse entre el médico y la mujer en cuya trompa flota un embrión. (shrink)

The aim of this work is to discuss "Darwinism: its past, its present, its future", a lecture given in 1875 by Miranda Azevedo as one of the "Popular Lectures of the Gloria Neighborhood, Rio de Janeiro". In this lecture Azevedo elaborates the concepts of evolution, human evolution, progress and the idea of man as the pinnacle of evolution and the master of the selective laws governing nature. We will analyze the article, published in 1876, that contains the full text of (...) Azevedo's lecture. Of particular importance is his affiliation to Haeckel, something already commented on in Brazilian historiography. But, unlike other studies devoted to the theme, I will examine in detail Azevedo's text, attempting to show how he relates hereditary and selective evolutionary processes to thinking about how future Brazilian generations could progress.

s book, Hermeneutic Dialogue and Social Science: A critique of Gadamer and Habermas, intends to present an account of debates on objectivity in the social sciences, in stressing the political and epistemological responsibility, in public spheres, to those who want to create a fairer understanding of societies and history, without demonizing natural enterprises or leaving social studies out of acute critical questioning. Key Words: dialogue • hermeneutic • social sciences • natural sciences • method.

The aim of this work is to present the thesis “On the Ontogenetic Evolution of the Human Embryo in its Relations with Phylogenesis,” by Affonso Regulo de Oliveira Fausto, published in Brazil in 1890. To our knowledge, it was one of the first Brazilian academic works focused specifically on evolution. It was also the first doctoral thesis that addressed the topic of recapitulation in order to analyze what was then called the progressive evolution of the human species in tandem with (...) the embryological development of the individuals that would constitute the Brazilian “type.” In the present work, we analyze the author’s thesis in relation to its sources, concepts, as well as the country’s political context at the time of its publication. Fausto’s text, in which he explicitly recognized the influence of Ernst Haeckel’s recapitulation theory, represents a window to understand better a concept of nation based on science and on the idea of inexorable progress that was accepted in Brazil at the end of the nineteenth century.

Protests and counter-protests seek to draw and direct attention and concern with confronting images and slogans. In recent years, as protests and counter-protests have partially migrated to the digital space, such images and slogans have also gone online. Two main ways in which these images and slogans are translated to the online space is through the use of emoji and hashtags. Despite sustained academic interest in online protests, hashtag activism and the use of emoji across social media platforms, little is (...) known about the specific functional role that emoji and hashtags play in online social movements. In an effort to fill this gap, the current paper studies both hashtags and emoji in the context of the Twitter discourse around the Black Lives Matter movement. (shrink)

The question of how the probabilistic opinions of different individuals should be aggregated to form a group opinion is controversial. But one assumption seems to be pretty much common ground: for a group of Bayesians, the representation of group opinion should itself be a unique probability distribution, 410–414, [45]; Bordley Management Science, 28, 1137–1148, [5]; Genest et al. The Annals of Statistics, 487–501, [21]; Genest and Zidek Statistical Science, 114–135, [23]; Mongin Journal of Economic Theory, 66, 313–351, [46]; Clemen and (...) Winkler Risk Analysis, 19, 187–203, [7]; Dietrich and List [14]; Herzberg Theory and Decision, 1–19, [28]). We argue that this assumption is not always in order. We show how to extend the canonical mathematical framework for pooling to cover pooling with imprecise probabilities by employing set-valued pooling functions and generalizing common pooling axioms accordingly. As a proof of concept, we then show that one IP construction satisfies a number of central pooling axioms that are not jointly satisfied by any of the standard pooling recipes on pain of triviality. Following Levi, 3–11, [39]), we also argue that IP models admit of a much better philosophical motivation as a model of rational consensus. (shrink)

Precarious work is a growing and alarming phenomenon. This paper analyses two of its distinctive normative features. First, precarity increases the risks workers face, blurring their capacity for prospection and lessening their security in accessing the opportunities associated with their jobs. Second, precarious work challenges workers’ collective action capacity. I will argue that both features threaten workers’ republican freedom. I develop the second point by presenting a conception of solidarity between workers and then showing how precarious work erodes it. On (...) the one hand, when the labour market is dualised, precarity is distributed unevenly and the risks undergone by groups of workers are different. Thus, dual labour markets create a potential conflict of interest between the preferences of different groups, insiders and outsiders. On the other hand, various economic changes hinder workers from acting based on shared purposes due to increased coordination costs. To the extent that workers’ power depends on their bonds and collective action, primarily through unions, the eclipse of their solidarity leaves them powerless and thus increases their domination. Finally, I consider various scenarios that could boost workers’ collective power. (shrink)

The Author describes briefly how, through the confluence of trie new medical specialties of Reproductive Medicine and Molecular Genetics, a wide avenue has been opened to the genetic diagnosis and therapy of the preimplantation embryo. Today, the human embryo in its early stages has become the object of medical experimentation. In the next future, we will see the advent of new techniques for microsurgical manipulation and gene therapy Embryo-fetal Medicine will grow actively. The Author, after briefly analyzing the origin, and (...) criticizing the meaning, of the term preembryo, condueles, on the basis of unbiased observation of the continuum of human life, that only an attitude of respect for life and the determination to extend to the early human embryo the benefits of (gene)therapy are consistent with the deepest medical-deontological traditions.

Habermas shares with Kant the commitment to the posible, the ideal and duty to be moral, and with Hegel, the critique of the abstract carácter of kantian possibility and ought-be, as well as the realistic attention to the conditions of the really posible and the ideal. In this paper I intend to show that the confluence of such motifs, Kantian and Hegelian, in Habermas’ thought allows us to detect the keys to a conception of what should be and the ideal (...) that does justice to the two essential features of what is really posible: the refence to the future and to conditions embedded in the real.

The objectives of the present study were to adapt a grief intervention program to family caregivers of patients with dementia, and assess its effectiveness in improving the symptoms of grief and other health-related variables. The intervention was based on Shear and Bloom's grief intervention program, with the necessary adaptations for use in the grieving process for a family member's illness. A total of 52 family caregivers of individuals with dementia participated. They were evaluated using a battery of self-report measures assessing (...) grief, overload, resilience, post-traumatic growth, experiential avoidance, health-related quality of life, and benefits of care. The results suggest that the program is effective in improving grief symptoms, caregiver burden, resilience, post-traumatic growth, and quality of life of family caregivers. It is necessary to create and implement interventions targeting caregivers' feelings and manifestations of ambiguous grief, because there is a lack of programs providing an efficient solution for the mental and physical health of caregivers, and because of the human and socioeconomic cost involved in neglecting this group.

No cabe entender la filosofía como una mera rapsodia de opiniones, ni de comentarios ad hoc, ni de retóricas solemnes... por más que puedan ser originales o ingeniosos. Los conceptos filosóficos —al igual que los términos de la ciencia o del propio lenguaje ordinario— están trabados, forman un sistema y sólo cuando se ha controlado en mayor o menor medida un territorio de conceptos e ideas, es posible confrontar ese pensamiento con otros. Incluso, a veces, es el criterio mismo de (...) «sistematización» la clave de una filosofía. Porque una filosofía no sólo puede ser ejercida de hecho como un sistema, sino que puede apelar a cierta coherencia y completud, representándose a sí misma como tal sistema.

We uncover fundamental dimensions of the process through which organizations embed the practice of fraternity through embarking on an organizational journey in the direction of the common good. Building on the latest encyclical of Pope Francis, _Fratelli Tutti_, about fraternal and social friendship, we offer insight into the understanding of what it means to become a fraternal organization and reflect on the key ethical and paradoxical challenges for organizations aiming at collectively contributing to the common good. We add to previous (...) work by characterizing this journey as a process involving unique ethical challenges that emerge from the paradoxes associated with this process and how this might change the nature of the relationships between organizations and others within the organizational landscape.

Alrededor del «año cero» de la era cristiana se cruzaron en la cosmopolita ciudad de Alejandría (Alexandria ad Aegiptum) las ideas de Necesidad (ananké), de tradición griega, y de Dios Creador, de tradición hebrea.

Any plausibly just market exchange must balance two conflicting moral considerations: non-worseness (Wertheimer, 1999) and euvoluntariness (true voluntariness; Munger, 2011). We propose an analytical theory of just market exchange that partly resolves this conflict.

La cuestión de España es un problema complicado, a la vez, filosófico e histórico.

En el número 8 de la revista mexicana Cuadrivio, lamentablemente desaparecida, se incluía el artículo titulado «La astuta excepción de lo humano» que ahora se reproduce. Respondía a una creencia inferida del antiguo calendario mesoamericano conocido como cuenta larga, que situaba el fin de la humanidad en el solsticio de invierno de 2012. En el artículo nos preguntábamos si tenía sentido hablar de la posibilidad del fin total de lo humano. Recordábamos algunos momentos en los que la Humanidad quedaba en (...) suspenso: la «Solución final/definitiva» (Endlösung) que tenía como objetivo el exterminio del pueblo judío (1945); o el uso de la bomba nuclear en una guerra generalizada. Salvado este camino, nos preguntamos: ¿está asegurada la continuidad de la Humanidad? El proceso de globalización en el que sobrevivimos, nos conduce a una situación de equilibrio inestable en la que cualquier parámetro que sobrepase un cierto valor puede provocar rupturas y singularidades, y extraños vínculos entre democracias y estados totalitarios difíciles de prever. Quizá estemos viviendo ya plenamente ese momento de donde saldrá un nuevo sujeto de la historia. (shrink)

Cells in multicellular organisms often do not intermingle freely with each other. Differential cell affinities can contribute to organizing cells into different tissues. Drosophila limbs and the vertebrate central nervous system are subdivided into compartments. Cells in adjacent compartments do not mix. Cell interactions mediated by Notch-family receptors have been implicated in the specification of these compartment boundaries. Two recent reports analyze the role of the Notch signaling pathway in the generation of an affinity boundary in the Drosophila wing.1,2 The (...) first report1 analyzes the connection between Notch and the actin cytoskeleton. The second report2 analyzes the differential requirements of Notch and the transcription factor Supressor of Hairless in generating the affinity boundary.
