Achieving effective generalization in machine learning models is particularly challenging with small datasets that have high dimensionality. The combination of numerous features and few training instances often results in overfitting and poor performance on unseen data. This study conducts an in-depth analysis of HYB-PARSIMONY’s performance on high-dimensional datasets and introduces a novel methodology that integrates HYB-PARSIMONY with Bayesian Optimization (BO) to address this issue through iterative feature and hyperparameter selection. The methodology employs HYB-PARSIMONY with multiple random seeds to identify features with the highest mean probability, followed by hyperparameter tuning using BO to further enhance model performance. The experimental results demonstrate that this combined approach leads to models that are not only parsimonious but also capable of generalizing better compared to previous methods. By iteratively refining feature selection and hyperparameters, the proposed approach provides a more robust framework for building accurate machine learning models, even in challenging problems with a large number of features. In conclusion, the integration of HYB-PARSIMONY and BO significantly improves model generalization and reduces feature complexity, making it a promising methodology for small and high-dimensional datasets.

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.

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.

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.

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.

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.

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.

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 article considers friendship as a channel for education and as one of its objectives, as it is a necessary ingredient for a fulfilled life. This requires an initial study of interpersonal relationships in the postmodern context, considering their opportunities and risks. Our aim is to draw a topography of these relationships by analysing texts by major thinkers of the last four decades. The result of this analysis is the core of the article, namely, that there are four categories which seem to give a proper account of the characteristics of interpersonal relationships in postmodernity and are relevant in education: 1) the questioning of the individual; 2) the appearance of the internet; 3) the recoveryof emotions; and, finally; 4) the extension of the feminine space. As a conclusion, they may all be said to have an ambivalent character that requires central issues in education to be reconsidered: the awareness and emotional regulation; the new constitution of identity and intimacy on the internet; education for male-female relationships, which now exist outside the sexual sphere, and preventing violence in these relationships; as well as how to educate for cooperation in an individualistic society.

We aim to map out the points of confluence between phronesis and emotion, as well as the nature of this confluence. We do so based on philosophical and psychological explanations of emotions and phronesis. Making sound decisions, which requires phronesis, is an important matter, but its relationship with emotions has only just begun to be studied. We propose that the interplay between phronesis and emotion is possible (rather than inevitable) because both have a cognitive-behavioural structure and because emotions are hierarchical. In the case of emotion, there are no gaps between the cognitive and behavioural dimensions, while phronetic acts can only manifest if cognitive and behavioural aspects are activated simultaneously. The confluence we identify is bidirectional and involves mutual enrichment in this dual dimension. On the one hand, phronesis enriches emotion because it involves extra subjective knowledge and allows emotion to be directed towards higher goals. On the other hand, emotions enrich phronesis because phronesis makes decisions based on sensitive preferences and because emotions confirm correctness in the context of moral decision making. Methodologically, this study is theoretical and interdisciplinary, as our approach is both philosophical and psychological. Philosophy helps us to improve the conceptual foundation of the construct, while psychology provides an analysis of the emotional process, allowing philosophy to understand how emotional evaluation-assessment and motivation lead to decision making.

This article aims to theoretically analyse so-called character friendship from the perspective of emotions. From this angle, our research enables us to distinguish different types of emotions, and we propose a conceptual model of the hierarchy of the emotions of character friendship and their influence on social behaviour. With this model in hand, the article discusses whether other-oriented emotions fully explain the emotional underpinnings of character friendship. We find other-oriented emotions to be ambiguous because they may or may not be selfless. Thus we question whether these emotions can adequately explain the bonding content of character friendship. We conclude that there is a higher affective tier related to moral emotions and moral behaviour, which we have labelled the ‘bonding feeling’. This feeling is described with reference to its historical precedents (Rof Carballo’s ‘affective warp’), thus explaining its particularity.
