Conspecific violence has been pervasive throughout evolutionary history. The current research tested the hypotheses that individuals implicitly categorize combative contexts (i.e., play fighting, status contests, warfare, and anti-exploitative violence) and use the associated contextual information to guide expectations of combative tactics. Using U.S. and non-U.S. samples, Study 1 demonstrated consistent classification of combative contexts from scenarios for which little information was given and predictable shifts in the acceptability of combative tactics across contexts. Whereas severe tactics (e.g., eye-gouging) were acceptable in (...) warfare and anti-exploitative violence, they were unacceptable in status contests and play fights. These results suggest the existence of implicit rules governing the contexts of combat. In Study 2, we explored the reputational consequences of violating these implicit rules. Results suggest that rule violators (e.g., those who use severe tactics in a status contest) are given less respect. These are the first studies to implicate specialized mechanisms for aggression that use contextual cues of violence to guide expectations and behavior. (shrink)

Los modelos de escritura están experimentando grandes transformaciones como consecuencia de la revolución tecnológica contemporánea. Aunque los cibertextos y los hipertextos no son realidades exclusivas de la cultura digital, pues se dan en contextos culturales precedentes, aportan formas de pensamiento alternativas, que pasan por implicaciones epistemológicas –el pensamiento en red–, estéticas –reformulación de la autoría– y éticas –exigen un compromiso por parte del receptor. En este trabajo se abordará dicha coyuntura comparando las escrituras literarias Hypertext Hotel (1992) y Leyenda mayor (...) de Ian Curtis (2017) con las escrituras audiovisuales +101 (2012) y Quién lo impide (2018) con el objetivo de comprender las transformaciones que suponen tanto en la experiencia estética como en el campo cultural digital. Para ello, se empleará una metodología comparatista que tenga en cuenta las concomitancias entre las dos series de escrituras. (shrink)

In this paper we describe an experimental test of the validity of the Pauli Exclusion Principle (for electrons) which is based on a straightforward idea put forward a few years ago by Ramberg and Snow (Phys. Lett. B 238:438, 1990). We perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a very simple structure, it poses deep conceptual and interpretational problems. Here we (...) describe the experimental method and recent experimental results, which we interpret in the framework of quon theory. We also present future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

Pathological tremor is a common but highly complex movement disorder, affecting ~5% of population older than 65 years. Different methodologies have been proposed for its quantification. Nevertheless, the discrimination between Parkinson’s disease tremor and essential tremor remains a daunting clinical challenge, greatly impacting patient treatment and basic research. Here, we propose and compare several movement-based and electromyography-based tremor quantification metrics. For the latter, we identified individual motor unit discharge patterns from high-density surface electromyograms and characterized the neural drive to a (...) single muscle and how it relates to other affected muscles in 27 Parkinson’s disease and 27 essential tremor patients. We also computed several metrics from the literature. The most discriminative metrics were the symmetry of the neural drive to muscles, motor unit synchronization, and the mean log power of the tremor harmonics in movement recordings. Noteworthily, the first two most discriminative metrics were proposed in this study. We then used decision tree modelling to find the most discriminative combinations of individual metrics, which increased the accuracy of tremor type discrimination to 94%. In summary, the proposed neural drive-based metrics were the most accurate at discriminating and characterizing the two most common pathological tremor types. (shrink)

ABSTRACT Data from digital technologies are increasingly integrated in public health research. In April of 2020, we interviewed a subset of participants who completed a survey approximately one month earlier. Using the survey, we contacted and interviewed participants who had expressed their willingness or unwillingness to share digital data for use in public health. We followed a directed content analysis approach for the analysis of the interview data. Among participants who had reported being unwilling to share data, concerns about privacy, (...) confidentiality, and the purpose of the research were cited. During the interviews, 76.9% of the participants who had who had previously indicated that they were unwilling to share their data, expressed willingness to share data in order to assist with COVID-19 prevention. Our results contribute to our understanding of people’s perspectives on sharing personal data and of the way their perspectives can vary as a function of potential uses of their personal information.

The chapter by Ana Romero-Iribas and Consuelo Martínez-Priego is both unique and timely insofar as it approaches the concern with atomisation and social connection from the perspective of a recent event: the Covid-19 pandemic. This has had a fragmenting consequence for both individuals and institutions, leading to loneliness and isolation. The chapter considers civic friendship to be a remedy to this. Civic friendship involves other-orientated emotions. It is a concern for both self and others, and aims at collective goods. (...) However, it is not just emotional—it also has a rational component. Thus conceived, civic friendship offers a solution to the problems of fragmentation from three perspectives. From the point of view of the sociological, it is a relationship that is based on trust between citizens and cooperating to promote shared interests’; from the point of view of political theory, it offers a defence to totalitarianism by promoting freedom; from a psychological point of view, civic friendship binds other-orientated emotions. Thus this chapter also illustrates how friendship transcends disciplines as the topic and discussion is situated between political philosophy and social and emotional psychology. Civic friendship cannot be reduced to the emotions—but it cannot exist without them either. According to Romero-Iribas and Martínez-Priego, civic friendship is characterised by other-orientated emotions. The action which results from these emotions is guided by concern for the shared life of the subject and the other. These emotions are therefore not utopian or altruistic (self-sacrificing), they are rational emotions and wholly suited to political life. In discussing civic friendship in these terms, this chapter does much to free the emotions from being confined to the personal view of friendship which would view than as idiosyncratic and irrational, and to put them on a rational and generalized basis in politics and society as a whole.

Counting models for a two conjunctive formula $F$, a problem known as $\sharp $2Sat, is a classic $\sharp $P complete problem. Given a 2-CF $F$ as input, its constraint graph $G$ is built. If $G$ is acyclic, then $\sharp $2Sat can be computed efficiently. In this paper, we address the case when $G$ has cycles. When $G$ is cyclic, we propose a decomposition on the constraint graph $G$ that allows the computation of $\sharp $2Sat in incremental way. Let $T$ be (...) a cactus graph of $G$ containing a maximal number of independent cycles, and let $\overline{T}=-E)$ be a subset of frond edges from $G$. The clauses in $\overline{T}$ are ordered in connected components $\{K_1, \ldots, K_r\}$. Each $, i=1,\ldots,r$ is a knot of the graph. The arrangement of the clauses of $\overline{T}$ allows the decomposition of $G$ in knots and provides a way of computing $\sharp $2Sat in an incremental way. Our procedure has a bottom-up orientation for the computation of $\sharp $2Sat. It begins with $F_0 = T$. In each iteration of the procedure, a new clause $C_i \in \overline{T}$ is considered in order to form $F_i = $ and then to compute $\sharp $2Sat$$ based on the computation of $\sharp $2Sat$$.

Friendship is an important bond in the personal and social growth of an individual and plays a prominent role during youth. Most scales to measure it are aimed at children and adolescents but none measure character friendship, a type of selfless friendship with ethical traits an d Aristotelian roots. Therefore, the aim of the research is to design and validate the youth Character Friendship Scale (CFS) in a sample of 1587 young Spanish people. The final version of the CFS is (...) composed of 35 items distributed over three dimensions: "Selfless love and intimacy" (21), "Trust" (7) and "Respect and forgiveness" (7) with ordinal reliability coefficients of 0.94, 0.79 and 0.7 respectively and good model fits (CFI = 0.986; TLI = 0.986; RMSEA = 0.043; SRMR = 0.054; GFI = 0.997). It is concluded that the CFS is a scale with good psychometric properties for measuring character friendship in young adults. The results obtained from its application will lead to a better understanding of the importance of character friendship for the socioemotional development or happiness of young adults and will enable the development of intervention programmes that enhance aspects of friendship such as trust, respect, forgiveness or mutual knowledge, which can facilitate collaborative relationships and contribute to social cohesion.

In this chapter I argue that one way in which friendship contributes to moral growth is by means of developing self-knowledge. The chapter starts out with an explanation of the privileged space that friendship offers for the cultivation of character. Next, the chapter develops the connection between friendship and self-knowledge. Here, the chapter makes a distinction between self-knowledge on the psychological level, and self-knowledge on the anthropological level. The chapter then turns to an analysis of the two proposed core texts (...) on friendship, Lewis' The Four Loves and Laín Entralgo's On Friendship, in order to articulate a pathway for character education at university.

This article studies the political dimension of friendship in Robert Guédiguian’s cinema, delving into the crucial role that conversation plays in this relationship, and taking Stanley Cavell’s thought as a main reference. Aristotle’s concept of civic friendship, along with its contemporary readings, and Cavell’s notion of conversation provide a theoretical frame for the analysis of three recent feature films directed by Guédiguian that present a strong thematic and narrative unity (and have barely received attention in previous scholarship): Les Neiges du (...) Kilimandjaro/The Snows of Kilimanjaro (2011), La Villa/The House by the Sea (2017) and Gloria Mundi (2019). Based on, but going beyond, Cavell’s moral theorisation of the filmic portrayal of human relationships, the analysis of these films has identified four milestones in the transformative process—both personal and political—that stems from conversation with friends: conformity, confrontation, acknowledgement and renewed community. In all three films, this process of change is not only presented as a progressive discovery of one’s own voice, but also as a progressive unmasking: both are necessary prerequisites for welcoming foreigners in need of acknowledgement and, consequently, for the renewal of community.

This essay discusses the idea that trust is a pre-rational, other-oriented emotion and it is constitutive of friendship practices regardless of the type of friendship. In particular, what we call ‘social friendship’ refers to a distinctive set of loose but lasting and cohesive bonds both among citizens within society (horizontal dimension) and between them and the state (vertical dimension), triggering solidarity and altruism. The other-oriented emotion of trust underpinning these social bonds–social friendship–in turn, is necessary for social justice to be (...) supported, legitimized, and furthermore demanded by society.

En la actualidad hay un renacer del interés académico por la amistad que se aborda desde múltiples disciplinas, tales como la Sociología (Spencer & Pahl, 2006), la Psicología (Hojjat & Moyer, 2017), la educación (Kristjánsson, 2022), la Política (Digeser, 2016) o las Relaciones Internacionales (Koschut & Oelsner, 2014). En filosofía, la amistad es un tema clásico que se ha abordado con interés variable en distintos momentos de la historia: para griegos y romanos fue relevante a nivel personal y político (Aristóteles, (...) 1994); los pre-modernos la concibieron como un vínculo fundamental para la estabilidad política y la administración de la justicia (Smith & Devere, 2010) y en la Ilustración siguió considerándose un vínculo valioso. A partir del siglo XIX se oscurece su papel social (Laín Entralgo, 1986) y solo a finales del XX se retoma su valor en el ámbito social, más allá del personal (Derrida, 1998). A pesar de esa atención renovada a la amistad, las investigaciones desde la antropología filosófica o la metafísica son hoy menos frecuentes que otras como las que se hacen desde la ética o la filosofía política, por lo que es relevante prestarle atención desde esta perspectiva que es la elegida en este capítulo. El objetivo es repensar la amistad en Leonardo Polo desde su antropología trascendental partiendo de una confluencia interesante entre este filósofo y Agamben: la apertura ontológica al plano existencial (trascendental, en terminología poliana). Argumentaré cómo, en continuidad con la antropología trascendental y prosiguiendo el pensamiento de Polo, la amistad puede incluirse de alguna forma en el ámbito trascendental, puede ser un “amor personal” que, como tal, radica en la persona, muestra a la persona y la hace crecer. De acuerdo con eso, la estructura del capítulo es la siguiente: explicaremos la confluencia metafísica entre ambos filósofos y el papel de la amistad en la apertura al ámbito existencial (epígrafe 2); seguiremos con los elementos de la antropología trascendental que permiten proseguir pensando la amistad (epígrafe 3); estudiaremos el amar personal y la posibilidad de los “amores personales” (epígrafe 4) y finalmente abordaremos la amistad como amor personal.

La irrupción de la inteligencia artificial, la consecución de los objetivos de inclusión, igualdad o de sostenibilidad económica, plantean en las sociedades occidentales diferentes alternativas de actuación educativa. Este nuevo entorno que habitamos ha provocado también una evolución en los desafíos éticos que se presentan en el mundo de la educación caracterizados por la complejidad de su resolución y por la pluralidad de escenarios y protagonistas involucrados en los mismos. Cuestiones referentes a ¿cómo posicionar al profesor ante la posibilidad del (...) aprendizaje y evaluación automatizada?, ¿cómo implementar el principio de no discriminación educativa en un aula en la que conviven alumnos con diferentes capacidades, habilidades e intereses?, ¿cómo replantear nuevos hábitos de vida en pro de la sostenibilidad planetaria?, ¿cómo integrar la enseñanza de los valores constitucionales del siglo XX con el progreso moral de la sociedad del siglo XXI? constituyen la hipótesis de partida. Se afirma por tanto, que la educación debe abrirse a otras cuestiones, relativamente novedosas y de origen tecnológico, político o económico, que trascienden ese horizonte e impactan directamente en ella, concretamente desde el punto de vista de la ética educativa. Se establece una análisis de los desafíos actuales y su prospectiva en el campo de la ética de la educación y se establecen tres nuevas categorías en el campo de estudio: triaje, digitalización y nuevos actores.

The question on guilt that Jaspers poses to the Germans was not only valid after the Holocaust, it can be raised to other peoples who must answer for the crimes committed by the state which act on behalf of the people that gave support to them. In this paper, I elaborate a notion of citizens’ political responsibility in order to argue to what extent—and under what circumstances—the citizens of a political community must respond for the deeds of the political institutions (...) that govern them. For that purpose, I try to explain Spinoza’s notion of political authority in relation to Jaspers’ notion of political guilt. This Spinozistic approach has the advantage of freeing us from moral guilt—a misleading notion in political arena as I will argue—but it demands from us a genuine self-reflective and therapeutic procedure that if applied to politics would reveal a different path from Jaspers’ guilt. The aim of this therapeutic is to bring about a profound change in the personal and political identity of both citizen and political community. (shrink)

This textbook presents the basics of philosophy that are necessary for the student and researcher in science in order to better understand scientific work. The approach is not historical but formative: tools for semantical analysis, ontology of science, epistemology, and scientific ethics are presented in a formal and direct way. The book has two parts: one with the general theory and a second part with application to some problems such as the interpretation of quantum mechanics, the nature of mathematics, and (...) the ontology of spacetime. The book addresses questions such as "What is meaning?", "What is truth?", "What are truth criteria in science?", "What is a theory?", "What is a model?" "What is a datum?", "What is information?", "What does it mean to understand something?", "What is space?", "What is time?", "How are these concepts articulated in science?" "What are values?" "What are the limits of science?", and many more. The philosophical views presented are "scientific" in the sense that they are informed by current science, they are relevant for scientific research, and the method adopted uses the hypothetical-deductive approach that is characteristic of science. The results and conclusions, as any scientific conclusion, are open to revision in the light of future advances. Hence, this philosophical approach opposes to dogmatic philosophy. Supported by end-of-chapter summaries and a list of special symbols used, the material will be of interest for students and researchers in both science and philosophy. The second part will appeal to physicists and mathematicians. (shrink)
