This paper examines folk theories of algorithmic recommendations on Spotify in order to make visible the cultural specificities of data assemblages in the global South. The study was conducted in Costa Rica and draws on triangulated data from 30 interviews, 4 focus groups with 22 users, and the study of “rich pictures” made by individuals to graphically represent their understanding of algorithmic recommendations. We found two main folk theories: one that personifies Spotify and another one that envisions it as a (...) system full of resources. Whereas the first theory emphasizes local conceptions of social relations to make sense of algorithms, the second one stresses the role of algorithms in providing a global experience of music and technology. We analyze why people espouse either one of these theories and how these theories provide users with resources to enact different modalities of power and resistance in relation to recommendation algorithms. We argue that folk theories thus offer a productive way to broaden understanding of what agency means in relation to algorithms. (shrink)

Ubico indicios de mitos nacionales analizando obras narrativas (de Borges y algunos otros autores), y dichos acerca de Borges, centrándome en cómo se verifica, en la narrativa de Borges, (y también en sus intervenciones públicas y en lo que se dice sobre su figura) la irrupción del peronismo. Propongo un cambio de escala: sin intentar interpretar los grandes momentos constitutivos entendiéndolos como mitos de origen, intento constituir series, de características cuasi-míticas, a partir de poner en relación a breves sintagmas que (...) se reiteran en distintas unidades narrativas. Elementos transversales, que van de un relato a otro. Sintagmas que se analizan tomando al conjunto de la obra de Borges como paradigma, y no sólo relatos aislados. En primer término, exploro ciertas constantes en algunos relatos del período 1945-54. Luego me detengo en una serie de versiones contemporáneas sobre un Borges ciego a quien un joven peronista ayuda a cruzar la calle. En tercer lugar. el tema de la aparición de relatos oníricos, literariamente enunciados, sobre personas con garra de pájaro, vinculándolos a los dilemas morales de la élite intelectual en los tiempos del primer peronismo. En tanto estos conjuntos tienen mucho en común con los mitos al ser reelaboraciones sucesivas de un elemento narrativo, podrían ser abordadas con métodos de análisis míticos propios de la antropología estructural. No obstante, el material utilizado tiene diferencias con las mitologías clásicas: a) tiene versiones orales, pero también escritas; b) hechos ficcionales, pero también históricos; c) admiten un orden cronológico verificable. Por lo tanto, arriesgo aquí una exploración metodológica y teórica más bien experimental, aunque deudora de Lévi-Strauss. Concluyo que en estos dos conjuntos se verifica el funcionamiento un sistema ideológico, que es el de la formación nacional argentina, con sus tensiones y crisis. (shrink)

Sexting has been defined as sending, receiving, or forwarding sexually explicit messages, images, or photos to others through digital platforms, and can assume more consensual or more abusive and violent forms. This study aims to explore the prevalence of abusive sexting in Portuguese adolescents and the psychological characteristics of sexting abusers in terms of emotional and behavioral problems, potential markers of psychopathy, childhood trauma and maltreatment, and different forms of aggression. A cross-sectional study was conducted with 4,281 participants, aged 12–20 (...) years, of whom 204 engaged in abusive sexting behaviors and 182 self-identified as being a non-consensual sexting victim. Abusive sexting was more common among boys and middle adolescents, and abusive sexting victims were more likely to be children of single-parent families. Engaging in abusive sexting and being a victim of abusive sexting were also related to behavioral and emotional problems, callousness, experiences of neglect and abuse in childhood, and various forms of aggression. Implications for future research and intervention are discussed. (shrink)

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.

El presente texto busca reflexionar en torno al mundo de las prácticas del cuerpo y su vínculo con cierto tipo de culturas juveniles que poseen como forma de vida la alteración corporal, y donde en la actualidad se puede observar –en nuestro país– una explosión de la experimentación con el tatuaje y con el piercing, y de manera más incipiente –pero también significativa– con los implantes, las escarificaciones, los branding, las expansiones y la variante de las suspensiones humanas; práctica sobre (...) la cual el artículo profundiza intentando dar cuenta del contexto social y cultural donde surge la suspensión humana; los procesos de apropiación que experimenta esta práctica a partir de la irrupción de culturas juveniles en las sociedades contemporáneas; los significados y procedimientos asociados a este ritual; y los nexos entre política, estética y modificación corporal.

La búsqueda de una educación ambiental basada en los principios de la sustentabilidad, está en el centro de la reflexión de la autora. El arte de educar implica, por parte de educadores y educandos, consiste en asumirse como seres sociales y complejos; inmersos en una realidad que exige un compromiso constante con el medioambiente. La libertad que podemos alcanzar en el mundo exterior -el cual habitamos en tanto cuerpos interrelacionados entre sí y respecto de su medio- tiene como requisito previo (...) el desarrollo de nuestra libertad interna. La propuesta implica una educación ambiental como proceso crítico de comunicación y reelaboración constante del conocimiento, donde se construyen realidades sobre la base de la paz y de un futuro compartido.

Este artículo reflexiona sobre algunas facetas de la descalificación al pensamiento libre, en paralelo a las inequidades de género. Se ejemplifica con la persecución a mujeres en distintas épocas a las que el poder destruyó, de un modo análogo a como la codicia del poder destruye la naturaleza. Realza el artículo la existencia de una diversidad de saberes, para los que se requieren puertas abiertas, superando los cerrojos excluyentes, cruzando los muros de la inequidad de género, de las injusticias sociales (...) y de los atropellos por razones étnicas y otras, y las actitudes destructoras de la naturaleza y de las culturas.

Amante de la verdad y de la libertad personal. Entre sus obras más profundas se encuentran las que componen su Curso de teoría del conocimiento y su Antropología trascendental.

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.

Mathematics is a critical part of much scientific research. Physics in particular weaves math extensively into its instruction beginning in high school. Despite much research on the learning of both physics and math, the problem of how to effectively include math in physics in a way that reaches most students remains unsolved. In this paper, we suggest that a fundamental issue has received insufficient exploration: the fact that in science, we don’t just use math, we make meaning with it in (...) a different way than mathematicians do. In this reflective essay, we explore math as a language and consider the language of math in physics through the lens of cognitive linguistics. We begin by offering a number of examples that show how the use of math in physics differs from the use of math as typically found in math classes. We then explore basic concepts in cognitive semantics to show how humans make meaning with language in general. The critical elements are the roles of embodied cognition and interpretation in context. Then, we show how a theoretical framework commonly used in physics education research, resources, is coherent with and extends the ideas of cognitive semantics by connecting embodiment to phenomenological primitives and contextual interpretation to the dynamics of meaning-making with conceptual resources, epistemological resources, and affect. We present these ideas with illustrative case studies of students working on physics problems with math and demonstrate the dynamical nature of student reasoning with math in physics. We conclude with some thoughts about the implications for instruction. (shrink)

In this paper I present a formalization of the theory of ideal concepts applied to the concept of God. It is done within a version of the Simplest Quantified Modal Logic (SQML) and attempts to solve three meta-problems related to the concept of God: the unicity of extension problem, the homogeneity/heterogeneity problem and the problem of conceptual unity.

La percepción de la vida se vincula a la actitud ante la muerte para abrirse a la experiencia estética en torno al Poema de Mio Cid y a las Coplas de Manrique. Los horizontes simbólicos que brotan de la épica y de la lírica acentúan la figura trágica del héroe, del caballero.

For more than a century the notion of a pre-established harmony between the mathematical and physical sciences has played an important role not only in the rhetoric of mathematicians and theoretical physicists, but also as a doctrine guiding much of their research. Strongly mathematized branches of physics, such as the vortex theory of atoms popular in Victorian Britain, were not unknown in the nineteenth century, but it was only in the environment of fin-de-siècle Germany that the idea of a pre-established (...) harmony really took off and became part of the mathematicians’ ideology. Important historical figures were in this respect David Hilbert, Hermann Minkowski and, somewhat later, Albert Einstein. Roughly similar ideas can be found also among British theorists, among whom Arthur Eddington, Arthur Milne, and Paul Dirac are singled out. Although largely limited to the period 1870–1940, the paper also considers Max Tegmark’s recent hypothesis of the universe being a one-to-one reflection of mathematical structures. (shrink)

In physics education, equations are commonly seen as calculation tools to solve problems or as concise descriptions of experimental regularities. In physical science, however, equations often play a much more important role associated with the formulation of theories to provide explanations for physical phenomena. In order to overcome this inconsistency, one crucial step is to improve physics teacher education. In this work, we describe the structure of a course that was given to physics teacher students at the end of their (...) master’s degree in two European universities. The course had two main goals: To investigate the complex interplay between physics and mathematics from a historical and philosophical perspective and To expand students’ repertoire of explanations regarding possible ways to derive certain school-relevant equations. A qualitative analysis on a case study basis was conducted to investigate the learning outcomes of the course. Here, we focus on the comparative analysis of two students who had considerably different views of the math-physics interplay in the beginning of the course. Our general results point to important changes on some of the students’ views on the role of mathematics in physics, an increase in the participants’ awareness of the difficulties faced by learners to understand physics equations and a broadening in the students’ repertoire to answer “Why?” questions formulated to equations. Based on this analysis, further implications for physics teacher education are derived. (shrink)

In a recent paper in this Journal, one of us argued against placing He above Be in Mendeleiev’s system of the elements. In it the goal was to dispute the notion that in Mendeleiev’s system of the elements the location of He should in fact lie above Be, which has a very similar electronic configuration, rather than above the noble gas column. That paper was based on rather old, Hartree–Fock limit studies on the strikingly limited non-additive contributions in the He3 (...) and He4 systems in contrast with the much larger non-additivity obtained for the Be3, Be4 and Be5 oligomers. In a recent benchmark multireference Averaged Quadratic Coupled Cluster results on Be2 and Be3 we showed that the delocalized non-additive contribution comprises 94 % of the binding energy of Be3. Here we use this and other pertinent information (drawn from the same paper) to conclude that He may not be associated with Be in Mendeleiev’s Table, despite their quite similar spectroscopic ground states. Furthermore, we use the new results to show that the large non-additivity implies that less than 2 % of the Be3 binding is located in each Be pair contained within the Be trimer. The rest of the interaction energy is necessarily delocalized over all three Be atoms. This might actually announce the bulk properties (i.e. “the electron gas”) that in solid-state physics explain the large electric and heat conduction for the solid Be metal. Thus, in the case of beryllium the metallic characteristics are already evident in Be3, a far cry from the monoatomic helium gas. (shrink)

O objetivo deste artigo é apresentar a relação entre Filosofia política e democracia na obra de Michael Walzer, a partir da influência exercida sobre ele por John Rawls. Para fazer isto, será feita uma breve apresentação das visões de Rawls sobre aquela relação. Após, será mostrado que Walzer corrobora e amplia a concepção de Rawls. Por último, será descrito o papel de crítica imanente que Walzer atribui à Filosofia política nas democracias contemporâneas, trazendo-a da pretensão de guia da política, baseada (...) na contemplação privilegiada de qualquer suposta ordem transcendente e vinculante, para um papel de engajamento comprometido apenas com a própria ordem democrática.

We prove that no restriction of the sine function to any (open and nonempty) interval is definable in $\langle\mathbf{R}, +, \cdot, , and that no restriction of the exponential function to an (open and nonempty) interval is definable in $\langle \mathbf{R}, +, \cdot, , where $\sin_0(x) = \sin(x)$ for x ∈ [ -π,π], and $\sin_0(x) = 0$ for all $x \not\in\lbrack -\pi,\pi\rbrack$.

Aurélio Agostinho, when he was consecrated bishop in Hippo, had contact with a community in a situation of extreme social inequality, and adding to his understanding of bidirectional love (to God and neighbor), translated into nonconformity with the suffering of others, in the function as a bishop he had the opportunity to fight with the weapons at his disposal for a less undignified life for the poorest. Therefore, the concept of poverty that appears between the lines of his texts and (...) sermons is translated as a lack of material resources that makes it impossible for people to get the basics for survival. Among the weapons used by the philosopher bishop is the exhortation in his sermons, which in addition to denouncing the intense inequality of society, pondered on ways to resolve this huge gap between rich and poor. Thus, in this article we will analyze Augustine's lucubrations in sermons: 345, 355, 60, 61, 161, 14, which critically reflect poverty and wealth. The aforementioned sermons stand out on the subject for their critical reflections, because, although they treat the rich and their accumulation of wealth very harshly, showing solidarity with the less favored, and at different times they also have a critical look at the poor they idealized as a dream., desire or life goal to possess riches.

We can communicate linguistic information by asserting sentences that are not explicitly about linguistic matters. Stalnaker offers a pragmatic account of this phenomenon. It is not clear that such an account is correct. In this article I offer an alternative account that does not rely on pragmatic mechanisms and which captures many of the insights in Stalnaker's theory of linguistic communication. The view is inspired by Barker's semantics of vague adjectives.

O presente artigo tem como objetivo investigar quais as diferenças epistêmicas entre a Fenomenologia do Espírito de Hegel e a Fenomenologia Pura de Husserl, possibilitando um comparativo de qual a relação entre a consciência de Deus nas possibilidades fenomenológicas. Inicialmente, o artigo se constitui pelos conceitos relacionados hegelianamente, que compõem a dimensão teológica de Hegel, realizando aprofundamento no modo como a consciência religiosa se presentifica e é vivida. Consequentemente, é abordado quais as questões essenciais que constituem a plataforma da fenomenologia (...) pura, como um ponto de partida apresentasse a intencionalidade e a epoché. Como conclusão, nota-se que o que constitui desvio significativo em cada fenomenologia é em Hegel o conceito de Deus e em Husserl o conceito de intencionalidade. (shrink)

In the broadest sense of the term, “Thomism” refers to a set of ideas and principles, both in philosophy and theology that can be considered as derivations or representations of the thought of Thomas Aquinas. However, Thomism should not be considered as a mere conceptual body. It also represents a certain view and way of doing philosophy and theology. Alasdair MacIntyre, in his book Three Rival Versions of Moral Enquiry, argues that the Thomistic approach provides a coherent and skillful point (...) of view for dealing creatively and critically with opposing views, contrasting this approach with the encyclopedic and the genealogical approaches. The former imposes a single worldview, enclosing knowledge and “truth” in a monolithic structure of “progress,” while the latter, following Nietzsche, devalues and relativizes knowledge, reducing it to a multiplicity of perspectives, each with its own claims to truth, leading to incommensurability and the consequent subjugation of “truth” to the law of the strongest. On the other hand, Thomists have adopted, from the end of the thirteenth century to the present day, different styles and ways of thinking while maintaining dialogue with their “predecessors” and at the same time with their contemporaries, that is, Thomists are capable of what MacIntyre called the “rationality of tradition”.

Relational Quantum Mechanics is an interpretation of quantum theory based on the idea of abolishing the notion of absolute states of systems, in favor of states of systems relative to other systems. Such a move is claimed to solve the conceptual problems of standard quantum mechanics. Moreover, RQM has been argued to account for all quantum correlations without invoking non-local effects and, in spite of embracing a fully relational stance, to successfully explain how different observers exchange information. In this work, (...) we carry out a thorough assessment of RQM and its purported achievements. We find that it fails to address the conceptual problems of standard quantum mechanics—related to the lack of clarity in its ontology and the rules that govern its behavior—and that it leads to serious conceptual problems of its own. We also uncover as unwarranted the claims that RQM can correctly explain information exchange among observers, and that it accommodates all quantum correlations without invoking non-local influences. We conclude that RQM is unsuccessful in its attempt to provide a satisfactory understanding of the quantum world. (shrink)

El artículo propone analizar algunos de los usos y relaciones que se establecen entre las nociones de norma y normatividad, tomadas en un sentido amplio, con los problemas tanto básicos como “aplicados” en el campo psicoeducativo. Para ello, se intentará una aproximación desde una perspectiva crítica y en el marco de los Enfoques Socio Culturales en psicología del desarrollo y educacional. La hipótesis de partida es que la psicología del desarrollo, abordada desde estos enfoques, y aún con mayor fuerza la (...) psicología educacional, poseen un ineludible componente normativo consistente con la caracterización de las prácticas pedagógicas como prácticas de gobierno del desarrollo, como prácticas que producen ciertos cursos de desarrollo subjetivo. Se procurará mostrar cómo la cuestión de lo normativo se imbrica, a su vez, con cuestiones básicas de la explicación del desarrollo. (shrink)

Sören Kierkegaard y Emmanuel Levinas son dos pensadores alejados en el tiempo y su pensamiento se desarrolla en contextos filosóficos diferentes. A pesar de esta primera divergencia, ambos pensadores coinciden en su defensa de la subjetividad. En la obra de Levinas se puede encontrar algún trabajo dedicado a valorar el significado y el alcance de la obra del pensador danés. En esos trabajos, Levinas se muestra crítico en relación con la defensa de la subjetividad de Kierkegaard y en relación a (...) su propuesta de la ¿suspensión religiosa de la ética¿. La defensa kierkegaardiana de la subjetividad es interpretada por Levinas como una variación de la concepción egológica del sujeto, dominante en la tradición occidental. Pese a esta valoración crítica, este trabajo pretende rastrear que en ambos autores el origen de la subjetividad remite a la experiencia de la temporalidad y, dentro de ella, a la cuestión del fluir temporal. Es en la interpretación del flujo temporal en donde el pensamiento de ambos autores vuelve a divergir. (shrink)

The ‘value-free ideal’ has been called into question for several reasons. It does not include “epistemic values”—viewed as characteristic of ‘good science’—and rejects the so-called ‘contextual’, ‘non-cognitive’ or ‘non-epistemic’ values—all of them personal, moral, or political values. This paper analyzes a possible complementary argument about the dubitable validity of the value-free ideal, specifically focusing on social sciences, with a two-fold strategy. First, it will consider that values are natural facts in a broad or ‘liberal naturalist’ sense and, thus, a legitimate (...) part of those sciences. Second, the paper will not reject the value-free ideal; rather, it will construe this ideal in a special way, not casting values aside in sciences, but bringing them to the table and rationally discussing them. Today’s predominant naturalistic view has tended to ‘naturalize’ values by looking for physicalist explanations for them—a move resisted by defenders of normativism in social sciences. At the same time, a contending ‘liberal naturalist’ stream has emerged, claiming that not all natural entities can be explained by the methods and concepts of physical sciences, and favors a non-materialist naturalism which includes mind, consciousness, meaning and value as fundamental parts of nature that cannot be reduced to matter. Hence, it may be posited that non-epistemic values could be ‘naturally’ included in the field of human sciences. (shrink)
