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)

This article seeks to reconsider some colonial and contemporary readings around a paradigmatic figure: Malintzin. With this objective I will divide our approach into four correlated sections. The first introduces some elements around the construction of the term Malintzin, highlighting those that are related with the Nahua cultural world. The second takes up the colonial chronicles of Bernal Díaz del Castillo and Diego Muñoz Camargo, identifying their specific contents related to her figure. The third delves into some contemporary contributions of (...) a literary, historiographical and philosophical nature. To this purpose I will recover the literary appreciations of Octavio Paz, the historical proposals of Matthew Restall, and the philosophical approach of Bolívar Echeverría. The fourth section functionalizes some final considerations related to Malintzin as useful perspective to problematize the contemporaneity of the conquest of Mexico. Lately, this article seeks to ask and reflect on Malintzin in terms of the construction of an imaginary that posits a multidirectional understanding of her figure. (shrink)

Many different arguments have been put forward in order to assign the best place for a given element within Mendeleev's Table: its spectroscopy, its chemical activity, the crystalline structure of its solid state, etc. We here propose another criterion; the nature of the few body corrections to the pairwise additive energy. This argument is used here to address a question often brought forward by Eric Scerri in Foundations of Chemistry, namely the rightful place of helium; either above the column of (...) the alkaline earths (beryllium, etc.) or rather above the noble gas elements.

The Periodic Table has the column of the noble gas atoms (He, Ne, Ar, Kr, Xe, Rn) as one of its main pillars. Indeed the inert chemical nature of their closed shell structure is so striking that it is sometimes extended to all such structures. Is it true however that any closed shell, say a closed d-subshell will denote a lack of chemical activity? Take the noble metals for instance, so renowned for their catalytic capacity. Platinum has 10 electrons in (...) its valence shell which makes one of its excited states to be a closed 5d10–6s0 state. Surely this state would not be expected to be crucial to the catalytic activity of platinum, or would it? Or take palladium whose ground state is precisely the 4d10–5s0 state, should we expect that an isolated Pd atom at near zero-point temperature would attack a closed-shell hydrogen molecule efficiently? We shall here show that this is precisely the case; the closed-shell excited states of nickel and platinum are indeed crucial, through symmetry avoided crossings, for their reactivity. Other valuable catalysts as ruthenium depend on their excited states with maximal d-shell occupancy for their activity. The most notable confirmation of this new finding; that closed d-shells are vital to the catalytic activity of noble metals however, is the case of palladium whose closed-shell ground state is indeed capable of attacking hydrogen and hydrocarbon molecules even at temperatures well below 10 K as was predicted theoretically and immediately confirmed experimentally.

Over the turn of the 21st century, the use of data from large electronic corpora has changed research on Spanish historical syntax, spurring interest in long-range evolutions and the shape of the correspondent diachronic curves. However, general reflections on diffusion and the factors that drive and influence it are still pretty much lacking. In this paper, I reflect on the research possibilities laid open by the availability of such large masses of data, focusing particularly on new knowledge on syntactic change (...) brought about by the study of low-frequency phenomena and of recessive changes, as well as on the exploration of changes conditioned by dialect contact and textual traditions. I conclude with some remarks on the general typology of diffusion in syntactic change. (shrink)

The literary genesis of Einbahnstraße by Walter Benjamin represents a very special case of the use of the procedures of surrealism in the philosophical-literary production of the author. The process of evolution of thinking that ended up in the writing of this piece is unveiled throughout the present analysis. This is a sign of both waiver and restart; the opening for a new productive dimension in the career of one of the most important —and misunderstood— philosophers of the 20th century. (...) More than enlightening a small master piece of philosophy from a literary perspective, or analyzing a small master piece of literature from the philosophy, what is being problematized here is the division, cultivated or figured throughout the years, between both disciplines. This work is intended to recover what is insoluble from the philosophical-literary labor of Walter Benjamin, besides tracing a possible reconfiguration for an interdisciplinary field of work to come up and contribute in the understanding of the problem called The Retreat of Metaphor by Jacques Derrida.

El propósito de este texto es tematizar la precariedad con las herramientas de la filosofía política. Buscaremos equilibrar horizontes conceptuales con prácticas políticas para pensar la acción democrática en nuestro contexto. Nuestro argumento se compone de cuatro premisas. Primero, que elfalso dilema entre teoría y práctica nos permite explorar una relación de tensión creativa entre ambas para conceptualizar la precariedad. Segundo, que la construcción teórica de la precariedad responde tanto a ideas y conceptos como a instituciones y discursos que configuran (...) las vidas de quienes la experimentan. Tercero, que los distintos usos del concepto de precariedad permiten reconocer una fuente común de vulneración de derechos relacionada con la configuración del trabajo en el orden neoliberal. Cuarto, que relacionar la conceptualización de lo plebeyo con la de lo precario nos permite pensar prácticas democráticas renovadas. (shrink)

This paper deals with the question of whether uncertainty regarding model structure, especially in climate modeling, exhibits a kind of “chaos.” Do small changes in model structure, in other words, lead to large variations in ensemble predictions? More specifically, does model error destroy forecast skill faster than the ordinary or “classical” chaos inherent in the real-world attractor? In some cases, the answer to this question seems to be “yes.” But how common is this state of affairs? Are there precise mathematical (...) results that can help us answer this question? And is dependence on model structure “sensitive” in that arbitrarily small errors can destroy forecast skill? We examine some efforts in the literature to answer this last question in the affirmative and find them to be unconvincing. (shrink)

En este trabajo se hace un análisis aproximativo del estudio fenomenológico hermenéutico del dolor en la facticidad del vivir propio. Su objetivo es visualizar el dolor como determinante en la apertura a la existencia del ser, del ser-ahí, en perspectiva heideggeriana. Se expone la experiencia de la vida dolorosa como experiencia fáctica del vivir en sí mismo, y el conflicto ético que plantea la alteridad: la dificultad de comprender el dolor de los otros desde su propio experimentar dolor. Este conflicto (...) ético aparece en la conciencia del médico cuando éste asume el compromiso de ir más allá de la ayuda instrumental e intenta ver el sufrimiento del enfermo desde la realidad del otro como sí mismo. La hipótesis que subyace en este análisis es que el sufrimiento del dolor abre camino a la existencia propia; sin embargo, evidencia el obstáculo de comprensión del otro. Se concluye ratificando la idea de que el dolor tiene carácter de «existenciario» (término de Martin Heidegger, que significa un modo de ser-en-el-mundo). (shrink)

Media ecology is not the theoretical stream of communication studies and it is not limited to Marshall McLuhan´s work and thinking; however, we focus on McLuhan’s approach to media ecology for this special issue on the philosophy of Marshall McLuhan. Media ecology is a complex and systemic metadiscipline whose object of study is the changes and effects that have occurred in society as a result of the evolution of technology and media throughout history.

Violence has long been assumed to be an intrinsic trait of female prostitution. However, it has been mostly associated with the locale in which the activity is exercised, i.e. with working time and space. In this article, based on data gathered by direct observations, in-depth interviews and the compilation of so-called time-budgets, the authors demonstrate that violence is as pervasive and omnipresent a feature of prostitutes’ ostensibly private ‘off-duty’ time and space, though it takes on varied and distinct forms and (...) configurations, compared to violence in the workplace.

This paper explores the political awakening of the Chilean people that began in October 2019. It puts forward an alternative reading of the people’s claim for a new constitution. The first section briefly describes the October outcry and provides some context with regards to the nature of the social movement at its root. The two following sections examine two periods in Chilean recent history, the Pinochet regime and the period that has come after its overturn, focusing on two elements: the (...) neoliberal model set up by the dictatorship and the Constitution of 1980, which was designed to block the people’s political agency for the purpose of protecting the model. The final section works with these two elements in order to provide an alternative scheme by which to examine Chile’s awakening, the central question being: what does the claim for a new constitution mean? And critical for these purposes: what constitution is being overturned? Pinochet’s political project distorted constitutional ideas in such a way that only by clarifying the conceptual horizon is it possible to visualize how the concept of constitution and its relationship with the idea of a constituent power of the people can be of help to understand Chile’s constitutional awakening.

In this essay I revise, based on the notion of the ‘enlightened ruler’ or mingzhu and his critique of the literati of his time, the common belief that Han Fei was an amoralist and an advocate of tyranny. Instead, I will argue that his writings are dedicated to advising those who ought to rule in order to achieve the goal of a peaceful and stable society framed by laws in accordance with the dao.

Argumentation represents a way of reasoning over a knowledge base containing possibly incomplete and/or inconsistent information, to obtain useful conclusions. As a reasoning mechanism, the way an argumentation reasoning engine reaches these conclusions resembles the cognitive process that humans follow to analyze their beliefs; thus, unlike other computationally reasoning systems, argumentation offers an intellectually friendly alternative to other defeasible reasoning systems. LogicProgrammingisacomputationalparadigmthathasproducedcompu- tationallyattractivesystemswithremarkablesuccessinmanyapplications. Merging ideas from both areas, Defeasible Logic Programming offers a computational reasoning system that uses an argumentation engine (...) to obtain answers from a knowledge base represented using a logic programming language extended with defeasible rules. This combination of ideas brings about a computationally effective system together with a human-like reasoning model facilitating its use in applications. (shrink)

The thought of Pierre Klossowski, praised by Foucault, Blanchot, Deleuze, has been scarcely addressed by the philosophical community. We argue in this article that this is largely due to the frequent difficulty of understanding his work as a whole: both his artistic and literary production and his interpretations of Nietzsche or Sade form a coherent whole, whose significance has a deeply critical political scope. The notion of unproductive spending, which occupies a central place in Bataille's work, will be rearticulated in (...) Klossowski's reflections through the concepts of drive, phantasm, simulacrum, value and consumption. In The Living Currency, the political dimension of these terms appears clearly: relying on a rereading of Fourier and Sade, the author shows the extreme degree of deformation of what we assume as a reality in modern industrial society. In this sense, his thinking takes on special relevance today, as a revelation of the excess and unhingedness of a society in which production and consumption are reproduced without limit through the infinite reflections produced by the game between drives, ghosts and simulacra.

In a recent issue of the Journal of Business Ethics, Filipe M. Santos posits that social entrepreneurs maximize not on value capture, but on value creation, only satisficing on value capture to fuel operations, reinvesting in growth, whatever the specific combination of institutional means is deemed appropriate. No doubt the analytical framework of value creation and value capture casts new light on the phenomenon of social entrepreneurship, but we think Santos is asking too much by advocating a shift in focus (...) away from the organization. On the contrary, we maintain that by refocusing the theory on the organizational level and away from the system it is possible to understand that not all organizational solutions available to social entrepreneurs are able to create value and not all value capture strategies can serve a social goal. Indeed, there is only one form of organization that fulfills the criteria of maximizing on value creation, while satisficing on value capture and that is the social enterprise. (shrink)

This paper critically explores the ethical dimensions of Behavioral Public Policy (BPP), a domain grounded in the understanding that human rationality is bounded and that this limitation often leads to behaviors deemed irrational. By applying the behavioral lens, which posits that people operate under bounded rationality, BPP aims to craft interventions that safeguard individuals against their biases. However, this approach raises significant ethical concerns, both in the scientific underpinnings of BPP and its application through policy interventions. Accordingly, this paper examines (...) two distinct ethical dimensions of BPP, both as a scientific discipline and through its intervention methodologies. The analysis of the first dimension argues that, viewing bounded rationality as only instrumental in decision-making processes, risks oversimplifying ethical complexities. Such simplification may ignore the moral and value-based rationalities underlying decisions, potentially misattributing instances of immorality and akrasia (the failure to act according to one's judgment) to mere deficiencies in rational thinking. Secondly, the paper examines the impact of BPP on moral behavior and character development, addressing ethical concerns like the evidentiary basis of BPP research, the bounded rationality of choice architects themselves, and the morality of behavior changes induced by policy. Overall, this article provides a much-needed examination of the moral considerations associated with behavioral strategies in public policy and its epistemological foundations, contributing to a more comprehensive understanding of their ethical implications .

Citizenship regimes are institutionalized systems of formal and informal norms that define access to membership, as well as associated rights and duties. This paper studies illegalized migration as one of the major tests to assess whether citizenship regimes are fair institutions, based on a historical analysis of legislation meant to reduce illegalized migration in the United States between 1995 and 2022. We build our empirical research starting from a simple observation: despite the great number of bills introduced to reduce illegalized (...) migration to the US, most of such initiatives fail to become law. In fact, 93.5% of all immigration initiatives did not even pass the chamber of Congress in which they were originally presented. Such a high rate of failure shows that these proposals are motivated by electoral aspirations, rather than coming from a genuine wish to help migrants or grant them citizenship. Furthermore, there is also an economic interest that justifies the maintenance of low-cost disposable immigrant labor, with no right to citizenship. Our analysis is an example of how state regulation processes seem to work to formalize, rather than alleviate or eradicate, the precarious legal statuses of illegalized migrants. We conclude that a globalized phenomenon such as citizenship requires going beyond merely institutional and formal conceptions. We need to rethink the institutional notion of citizenship, as a merely status held under the authority of a state and consider it from a cosmopolitan perspective and a multilateral basis. But as long as citizenship remains under the responsibility of states, illegalized migrants will continue to experience precarious citizenship. (shrink)

Nudging and sludging are forms of choice architecture that shape behavior. While it is generally believed that nudging should improve well-being and sludging should decrease it, there has been debate about how to distinguish between the two. Some have suggested that the difference lies in the ease with which behaviors are facilitated or hindered, but this criterion does not consider the normative distinction (nudges have a positive connotation and sludges a negative one) or the impact on well-being. This paper proposes (...) a normative approach to defining nudging and sludging that takes into account both well-being and the principle of autonomy. According to our proposal, the concept of nudging should involve interventions that aim to increase well-being while respecting individuals’ freedom of choice, while sludging involves interventions that decrease well-being while also respecting autonomy, whether intentionally or unintentionally.

Teacher quality, its effect on students’ outcomes, and the association of these with economic growth, is the core of recent discussions in Latin America given the region’s weak results in international learning assessments. This paper investigates whether there is an effect of philosophy on the outcomes of critical reading for students in B.Ed. programs in Colombia. Relying on exact matching combined with propensity score matching with regression adjustment, we use national data from Colombia to show that students in B.Ed. in (...) philosophy outperformed students in other B.Ed. in critical reading test (0.401–0.124 SD), and, importantly, with higher effects observed for students with lower prior academic achievement (0.44 SD). This suggests that philosophy can help to narrow educational outcomes of students whose socioeconomic conditions are disadvantageous, contributing to social justice in education. (shrink)
