We estimate the influence of classmates? ability characteristics on student achievement in exogenously formed university student groups. The study uses administrative data on undergraduate students at a large selective university in Russia. The presence of high-ability classmates has a significant positive effect on individual grades in key economics and mathematics courses as well as on overall academic performance. While a simple linear-in-means model reveals moderate peer effects, non-linear specifications give strong evidence that students at the top of the ability distribution (...) derive the greatest benefit from high-ability classmates. Less able students are not affected by peers and have no significant influence on peers? outcomes. (shrink)

La discussione generale sulla filosofia della scienza contemporanea è complicata dal numero e dall’eterogeneità delle scienze, mentre lo studio di temi specifici porta inevitabilmente a dissertazioni specialistiche che mancano nel dare ragione della trama di senso sottostante. Questo Piccolo trattato di epistemologia intende occupare uno spazio vuoto, proponendo alcuni temi chiave per la comprensione dei meccanismi alla base della conoscenza scientifica: i rapporti tra filosofia e scienze, siano esse naturali o umane; la complessa relazione tra fatti e valori; la distinzione (...) tra scoperta e giustificazione; la necessità di un discorso etico sulla ricerca, che chiami in causa categorie come fiducia, empatia, altruismo ed egoismo. Con un approccio chiaro e rigoroso, il volume intende rivolgersi a quell’ampia fascia di pubblico interessata alle tematiche centrali dell’epistemologia, della filosofia e delle scienze. (shrink)

Previous research indicates positive effects of a person’s attractiveness on evaluations of opposite-sex persons, but less positive or even negative effects of attractiveness on same-sex evaluations. These biases are consistent with social motives linked to mate search and intrasexual rivalry. In line with the hypothesis that such motives should not become operative until after puberty, 6- to 12-year-old participants (i.e., children) displayed no evidence for biased social evaluations based on other people’s attractiveness. In contrast, 13- to 19-year-old participants (i.e., adolescents) (...) displayed positive and negative attractiveness biases toward opposite- and same-sex targets, respectively. Moreover, these biases increased with the age—and thus the reproductive relevance—of the targets being evaluated. Findings corroborate the relevance of mating-related motives for social judgment and illustrate how such biases can grow during human development. At a broader conceptual level, this research demonstrates the utility of investigating proximate social judgment processes through the lens of adaptationist thinking. (shrink)

Razón, poesía, historia.--La cuestión del estoicismo español.--El querer.

The passage of time seems to be a fundamental aspect of experience. However, most descriptions of the passage of time itself are incompatible with the four-dimensional block universe model of space and time, in which time is extended like space, and all states of affairs exist equally and eternally in this varied tapestry of space and time. The tension between temporal passage and the block universe seems to leave one with the option of either abandoning the block universe in favor (...) of a metaphysics that can accommodate our experience, or holding that this experience of passage is illusory. I argue for a third option: that we have certain dynamic experiences, which lend themselves to the view that time passes, those dynamic experiences can be accounted for within the block universe model without any additional mechanism, and those dynamic experiences are not illusory, but veridical.

This edited collection considers how feminist strategies and philosophies might initiate, reshape, and critique approaches to library reference services.

El estudio comparativo de la Ley de Prensa de Brasil y la ley de Servicios de Comunicación Audiovisual de Argentina es el análisis empírico de la construcción de un paradigma en la teoría de la comunicación basado en el estudio de la filosofía de G. W. Leibniz, tomando como pilares la filosofía y teoría de la comunicación de Jürgen Habermas y las ideas de complejidad y paradigma de Edgar Morin.

El punto de partida de este artículo es que tanto el trabajo de J. Rawls La teoría de la Justicia, como la Teoría Feminista han contribuido enormemente al resurgimiento de la Filosofía Moral y Política. Mi objetivo aquí es mostrar las relaciones existentes entre la Teoría de Rawls y la Teoría Feminista, y particularmente analizar las críticas feministas de "justice as fairness" en el contexto de un estudio más general sobre Teorías contemporáneas de la Justicia y sobre la relación de (...) la Justicia en Teorías Feministas.

El trabajo doméstico y las labores domésticas se asocian, incluso hoy, con “lo femenino”, desde una perspectiva esencialista del género. Gracias a la obra de Beauvoir podemos indagar el género como una construcción social que asigna los roles y papeles que cada quien debe cumplir en una sociedad, para comenzar a señalar que la idea del “ama de casa de tiempo completo”, no es en absoluto una categoría que ha existido siempre, sino que está situada dentro de un contexto histórico (...) que sirvió para impulsar el desarrollo capitalista, como señala Silvia Federici. La perspectiva del feminismo materialista de Christine Delphy ofrece una crítica al marxismo clásico que ignora las condiciones de opresión y explotación de las mujeres. Presentamos un análisis sobre la manera en que el desarrollo del capitalismo y, al mismo tiempo, del patriarcado, ha atado a las mujeres a situaciones de violencia a partir de la dependencia económica.

RESUMEN El texto explora, en mujeres mayores de 80 años, la experiencia vivida durante el pe ríodo conocido como La Violencia en Colombia. Se examina el "trauma" que, según la autora, se manifiesta como "rayones", lo que hace difícil traducirlo o interpretarlo, porque solo se percibe a través de la escucha. Se estudia lo que M. Heidegger exploró como "ser-ahí" y "ser-en-el-mundo", esto es, el estar lanzados al mundo en un de terminado contexto donde construimos nuestra subjetividad y aprendemos a (...) vivir, para entenderlo mediante estas experiencias femeninas singulares. ABSTRACT The text explores the experience lived during the period known as The Violence in Colombia by women now over 80. It examines the "trauma" that, according to the author, manifests itself in the form of "scratches", thus making it difficult to translate and interpret given that it is only perceptible through listening. The article discusses M. Heidegger's notions of Dasein and being-in-the-world, that is, our thrownness into the world in a specific context in which we construct our subjectivity and learn how to live, in order to understand them through these singular feminine experiences.

The proliferation of for-profit enterprises offering stem cell storage services for personal use illustrates one of the ways health is increasingly governed through uncertainty and speculative notions of risk. Without any firm guarantee of therapeutic utility, commercial stem cell banks offer to store a range of bodily tissues, signalling the further transformation of the living body into an accumulation strategy within biotechnology capitalism’s ‘tissue economies’. This article makes two related claims: first, it suggests that specifically gendered forms of identification with (...) the leading edge of the bioeconomy are embedded in the speculative practices of commercial stem cell banking and are particularly visible in the recent creation of a banking service for endometrial tissue marketed directly to women. Second, the article offers a novel analytic through which to explore the commercial banking of one’s own bodily tissues (or ‘autologous’ banking) through Marx’s discussion of money hoarding. The aim of the article is to thus further the conceptual claims linking emergent forms of economic and biomedical subjectivity to transformations in biotechnology capital. (shrink)

«Fortaleza» y «debilidad» son dos adjetivos que se han utilizado prolijamente en la literatura científica sobre institucionalismo para describir la permanencia o, por el contrario, la porosidad y maleabilidad de las reglas y principios rectores en los que están atrincheradas las instituciones que sobreviven en equilibrio y, por tanto, no son alteradas unilateralmente.

Alongside the renowned male pioneers of medical cytogenetics, many women participated in investigations at the laboratory bench and the bedside, both in Europe and the Americas. These women were committed to this new biological and clinical practice—cytogenetics, the origins of contemporary genetic diagnosis—and contributed to the creation of new biological concepts and settings centered on the study of chromosome imaging. This paper will review the contributions made by a group of woman scientists from a wide geographical distribution, situating their names (...) and research agendas within the history of a field dating back to early plant and insect cytogenetics. Rather than an exhaustive compendium of women geneticists, this essay presents a kind of historical reconstruction that can be achieved by placing women at center stage in their geographies and networks of circulating cytogenetic knowledge and practices thereby relating a history of genetic images though the work carried out by women, retrieving their agency and constructing an inclusive history of an influential contemporary biomedical practice as it gained increasing influence in the laboratory and the clinic.

'Ethics' was not developed as a separate branch of philosophy in Buddhist traditions until the modern period, though Buddhist philosophers have always been concerned with the moral significance of thoughts, emotions, intentions, actions, virtues, and precepts. Their most penetrating forms of moral reflection have been developed within disciplines of practice aimed at achieving freedom and peace. This Element first offers a brief overview of Buddhist thought and modern scholarly approaches to its diverse forms of moral reflection. It then explores two (...) of the most prominent philosophers from the main strands of the Indian Buddhist tradition – Buddhaghosa and Śāntideva – in a comparative fashion. (shrink)

Since the 1970s, many Anglo-American studies have investigated the theme of corporate social responsibility (CSR) and its costs and benefits. Most studies have tried to test, largely in samples of multiple industries, the relationship between corporate social performance (CSP) and corporate financial performance (CFP). These analyses, however, have produced conflicting results and any attempt to give a generalized and coherent conclusion has proved inadequate. This article examines the ways CSP can be proxied and investigates the possible relationship between CSP (measured (...) by ethical rating) and CFP (measured by market and accounting ratios) in the banking sector using correlation methodology. It emerges that there is no statistically significant link between CSP and CFP. (shrink)

The present paper stems from the biosemiotic modelling of individual artificial cognition proposed by Ferreira and Caldas (2012) but goes further by introducing the concept of Umwelt Overlap. The introduction of this concept is of fundamental importance making the present model closer to natural cognition. In fact cognition can only be viewed as a purely individual phenomenon for analytical purposes. In nature it always involves the crisscrossing of the spheres of action of those sharing the same environmental bubble. Plus, the (...) incorporation of that concept is vital to understand the complex semiosis that sustains collective tissues, societies, regulating collective cognition and consequently cooperative action. The concept of Umwelt Overlap broadens the range of applicability of the previous model to several distinct domains allowing for example for its application to multi-agent cooperative autonomous systems. In this paper a Middle Size League RoboCup soccer team is used as an example of a possible application. (shrink)

In current debates about coming to terms with individual and collective wrongdoing, the concept of forgiveness has played an important but controversial role. For a long time, the idea was widespread that a forgiving attitude — overcoming feelings of resentment and the desire for revenge — was always virtuous. Recently, however, this idea has been questioned. The contributors to this volume do not take sides for or against forgiveness but rather examine its meaning and function against the backdrop of a (...) more complex understanding of moral repair in a variety of social, circumstantial, and cultural contexts. The book aims to gain a differentiated understanding of the European traditions regarding forgiveness, revenge, and moral repair that have shaped our moral intuitions today whilst also examining examples from other cultural contexts (Asia and Africa, in particular) to explore how different cultural traditions deal with the need for moral repair after wrongdoing. -/- .

In Ennead III.5 On Love, Plotinus' discussion of erôs is underlined by Plato’s discourse on love in the Symposium and the Phaedrus.[1] Plotinus conceives erôs as a purified power, which directs the soul to the intelligible realm of beauty and the world of the Forms.[2] Modern scholarship considers the Plotinian erôs as an ascending power that is always directed to the higher realm of the Forms and never to the lower perceptible realm. Throughout the Enneads, the soul is described as (...) purely and originally an intelligible entity in all its manifestations and expressions (ex. Ennead IV.8).[3] Plotinus particularly supports a dual aspect theory of the soul, in which the homogenous psychē consists of two interrelated aspects - a higher intelligible part related to Intellect, and a lower perceptible part related to the sensible bodies (Caluori, 2015; Remes, 2007; Stamatellos, 2013; Stern-Gillet, 2009). However, limited attention has been paid to the intelligible aspects of the soul's desire in Plotinus' conception of erôs. In this context, this paper aims to revisit the view that Plotinus completely refuted the desire of the physical bodies, and consequently refuted erôs as a power directed to the lower perceptible realm (Ferwerda, 1965; Friedländer, 1964; Hadot, 1963; Wallis, 1995). It is argued that in light of the soul's intelligibility, desire also has an intelligible aspect when it is directed, along with the power of love, to the earthly realm and thus the true intelligible beauty of the perceptible bodies is recognized. [1] Hereafter, all quotations from Plotinus’ Enneads will solely refer to Armstrong’s (1966-1988) translations. [2] See Bertozzi (2012, 2021); Tatarkiewicz (1980); Wallis (1995); Wiitala (2013), Vasilakis (2021). [3] For Plotinus’ theory of the soul, see his treatises in Ennead IV. Also see Blumenthal (1971) and Caluori (2015). (shrink)

The social and cultural changes of the last century have transformed death from an everyday fact to something hidden from view. Shifting between the practical and the theoretical, the professional and the intimate, the real and the fictitious, this collection of essays explores the continued power of death over our lives. It examines the idea and experience of death from an interdisciplinary perspective, including studies of changing burial customs throughout Europe; an account of a"dying party" in the Netherlands; examinations of (...) the fascination with violent death in crime fiction and the phenomenon of serial killer art; analyses of death and bereavement in poetry, fiction, and autobiography; and a look at audience reactions to depictions of death on screen. By studying and considering how death is thought about in the contemporary era, we might restore the natural place it has in our lives. (shrink)

Para tanto, parte do modo fundamental de registro do tempo: o histórico, apoiado na experiência e na memória e secundado pelos sistemas sígnicos e pelos aparelhos ideológicos, e examina as transformações que a concepção de tempo sofre ao integrar uma narrativa literária (...) nos seus dois planos compositivos: o da fábula e o do emedo. São utilizados como textos-modelo fragmentos de um episódio da Ilíada, de Homero e de um capítulo do Ulisses, de Joyce. (shrink)

Abstractabstract:As part of a Christian-Buddhist-Muslim trialogue on comparative theological concepts, this article examines Islamic conceptions of both myth and history in relation to different theological conceptions of time. Focused particularly on a comparison with Jewish and Christian traditions, this article argues that myth, while present in the Islamic tradition, plays a comparatively minor role, and one that does not align with some theoretical conceptions of how myth functions in other religious traditions. By contrast, history, as the arena of God's agency (...) in the world, is as important and well developed in Islam as it is in Judaism and Christianity. Unlike these latter two traditions, however, the Islamic and especially Qur'anic conception of sacred history is not only structured on a predominantly linear, progressive conception of time, but also considers historical time as unfolding in cyclical and circular patterns. The effect is a more variegated conception of theological time, which effectively blurs the lines between myth, sacred history, and religious/communal history. (shrink)

Apresentação do Dossiê "Relações Étnico-raciais, Branquitude e Decolonialidade na Educação".

Counselling acts consist in indicating useful activities, remedying human deficiencies. Counselling acts are guided by practical cognition. Since counselling activities are oriented towards the future, their crucial element is foresight. It is cognitive reflection foreseeing the implementation of counselling acts. Counselling acts are actualised in rhetorical and communicational context which is associated with persuasive delivery of counselling content. Belonging to the rhetorical canon, invention disposes of factors that influence the justifying formulation of advisory content. Invention factors introduce the anticipatory determinations (...) and concretisations of counselling content. At rhetorical level, inventive methodology plays anticipatory functions which are convergent with tasks of foresight in practical cognition. (shrink)

This paper aims to trace the links between Leopardi’s linguistic reflection and his theory of assuefazione, a theory that focuses on the functions of perception and the imaginative faculty within cognitive mechanisms. This theory also explains the functioning of the modalities with which human knowledge is articulated, starting from the experiential data, and therefore linguistic knowledge, in terms of a metaphorical apperception of the world. Specific attention will also be given to the notion of semantic vagueness, closely linked to the (...) general concept of indefinite: a concept that Leopardi develops in his reflections on the theory of pleasure and which is fundamental to define the peculiarities of the imaginative faculty. Furthermore, through the Garronian study of metaoperativity a more in-depth reading of the leopardian theory of assuefazione and of the link between perception and imagination too, as well as the role these two last faculties play in language will be provided. Precisely the metaoperativity allows us to explain and define with greater clarity the disposizione a poter essere, that is a precondition in order to conceive the Leopardian notion of indefinite. This conceptual clarification will also be important to highlight how the thought of Leopardi – in spite of the asystematicity that characterizes Zibaldone – is structured and deeply coherent, in line with that unitary and global approach to human knowledge of its time: an approach in which linguistic reflection and the theory of knowledge mutually imply each other, tightened by a relationship of mutual relevance.
