We study preferences over lotteries which do not necessarily satisfy completeness. We provide a characterization which generalizes Expected Utility theory. We show in particular that various sure-thing axioms are needed to guaranteee the representability in terms of utility intervals rather than numbers, and to provide a linear interval order representation which is very much in the spirit of Expected Utility theory.

We formulate and investigate experimentally a model of how individuals choose between time sequences of monetary outcomes. The model assumes that a decision maker uses, sequentially, two criteria to screen options. Each criterion only permits a decision between some pairs of options, while the other options are incomparable according to that criterion. When the first criterion is not decisive, the decision maker resorts to the second criterion to select an alternative. We find that: (1) traditional economic models based on discounting (...) alone cannot explain a significant (almost 30%) proportion of the data no matter how much variability in the discount functions is allowed; (2) our model, despite considering only a specific (exponential) form of discounting, can explain the data much better solely thanks to the use of the secondary criterion; (3) our model explains certain specific patterns in the choices of the “irrational” people. We reject the hypothesis that anomalous behavior is due simply to random “mistakes” around the basic predictions of discounting theories: deviations are not random and there are clear systematic patterns of association between “irrational” choices.

In this paper, we examine the problems facing a policy maker who observes inconsistent choices made by agents who are boundedly rational. We contrast a model-less and a model-based approach to welfare economics. We make the case for the model-based approach and examine its advantages as well as some problematic issues associated with it.

The aim of the present study was to investigate the association between attachment dimensions and neural correlates in response to the Rorschach inkblots. Twenty-seven healthy volunteers were recruited for the electroencephalographic registration during a visual presentation of the Rorschach inkblots and polygonal shapes. The Attachment Style Questionnaire was administered to participants. Correlations between the ASQ scores and standardized low-resolution brain electromagnetic tomography intensities were performed. The Rorschach inkblots elicited several projective responses greater than the polygonal shapes. Only during the Rorschach (...) inkblots presentation, discomfort with closeness and relationships as secondary subscales were negatively correlated with the activation of right hippocampus, parahippocampus, amygdala, and insula; need for approval subscale was negatively correlated with the activation of orbital and prefrontal cortex and left hippocampus. Moreover, the correlations between attachment dimensions and neural activation during the Rorschach inkblots were significantly higher compared to the same correlations in response to polygonal shapes. These findings suggest that attachment style can modulate brain activation during the projective activity of the Rorschach inkblots. (shrink)

Frida Kahlo (1907–1954) was a Mexican artist who is remembered for her self-portraits, pain and passion, and bold, vibrant colors. This work aims to use her life story and her artistic production in a longitudinal study to examine with quantitative tools the effects of physical and emotional pain (rage) on artistic expression. Kahlo suffered from polio as a child, was involved in a bus accident as a teenager where she suffered multiple fractures of her spine and had 30 operations throughout (...) her lifetime. She also had a tempestuous relationship with her painter husband, Diego Rivera. Her physical and personal troubles however became the texture of her vivid visual vocabulary—usually expressed through the depiction of Mexican and indigenous culture or the female experience and form. We applied color analysis to a series of Frida's self-portraits and revealed a very strong association of physical pain and emotional rage with low wavelength colors (red and yellow), indicating that the expression of her ailments was, consciously or not, achieved by increasing the perceived luminance of the canvas. Further quantitative analysis that used the fractal dimension identified “The broken column” as the portrait with higher compositional complexity, which matches previous critical acclaim of this portrait as the climax of her art. These results confirm the ability of color analysis to extract emotional and cognitive features from artistic work. We suggest that these tools could be used as markers to support artistic and creative interventions in mental health. (shrink)

Narcolepsy type 1 deeply impacts on quality of life, especially during adolescence, with NT1 children and adolescents that frequently report difficulties in integration with peers and decreased participation in after-school activities. Here we describe the case of NT1 teenager girl presenting with severe physical and social withdrawal, fulfilling the proposed diagnostic criteria for hikikomori, together with the classic NT1 symptoms. Social withdrawal is an overlooked phenomenon among NT1 children and adolescents that, if present, require a multidisciplinary approach and personalized interventions, (...) but patients can benefit from NT1 pharmacological treatment.

In this paper we deal with the extension of Nash bargaining theory to nonconvex problems. By focussing on the Social Welfare Ordering associated with a bargaining solution, we characterize the symmetric Nash Bargaining Solution (NBS). Moreover, we obtain a unified method of proof of recent characterization results for the asymmetric single-valued NBS and the symmetric multivalued NBS, as well as their extensions to different domains.

Sufficientarianism is a prominent approach to distributive justice in political philosophy and in policy analyses. However, it is virtually absent from the formal normative economics literature. We analyze sufficientarianism axiomatically in the context of the allocation of 0–1 normalized well-being in society. We present three characterizations of the core sufficientarian criterion, which counts the number of agents who attain a “good enough” level of well-being. The main characterization captures the “hybrid” nature of the criterion, which embodies at the same time (...) a threshold around which the worst off in society is prioritized, and an indifference to equality in other regions. The other two characterizations relate sufficientarianism, respectively, to a liberal principle of noninterference and to a classic neutrality property. (shrink)

This perspective paper aims at discussing theoretical principles that could explain how emotion regulation and physical diseases mutually influence each other in the context of borderline personality disorder (BPD). Furthermore, this paper discusses the clinical implications of the functional relationships between emotion regulation, BPD and medical conditions considering dialectical behavior therapy (DBT) as a well-validated therapeutic intervention, which encompasses these issues. The inflexible use of maladaptive emotion regulation strategies (e.g., suppression, experiential avoidance, and rumination) might directly increase the probability of (...) developing physical diseases through a physiological pathway, or indirectly through a behavioral pathway. Some metabolic and chronic medical conditions could significantly impact emotional functioning through biological alterations involved in emotion regulation. Several empirical studies have shown high co-occurrence rates between BPD and several chronic physical diseases, especially ones linked to emotion-based maladaptive behaviors. DBT addresses physical diseases reported by individuals with BPD reducing problematic behaviors functionally associated to emotion dysregulation and identifying physical health as a goal forBuilding a Life Worth Living.

We propose a new principle of 'non-interference' applied to social welfare orderings. The principle, together with two other standard requirements, implies a strong egalitarian conclusion: the ordering must lexicographically maximize the welfare of the worst off.

We study a principle of ‘Non-Interference’ in social welfare judgements. Non-Interference captures aspects of liberal approaches (particularly a Millian approach) to social decision making. In its full generality, Non-Interference produces an impossibility result: together with Weak Pareto Optimality, it implies that a social welfare ordering must be dictatorial. However, interesting restricted versions of Non-Interference are compatible with standard social welfare orderings.

We model opportunities in society as ‘chances of success’, that is as they are commonly described by practitioners. We show that a classical liberal principle of justice together with a limited principle of social rationality imply that the social objective should be to maximise the chance that everybody in society succeeds. Technically, this means using a ‘Nash’ welfare criterion. A particular consequence is that the failure of even only one individual must be considered maximally detrimental. We also study a refinement (...) of this criterion and its extension to problems of intergenerational justice. (shrink)

We analyse the liberal ethics of noninterference in social choice. A liberal principle, capturing noninterfering views of society and inspired by John Stuart Mill's conception of liberty, is examined. The principle expresses the idea that society should not penalise individuals after changes in their situation that do not affect others. An impossibility for liberal approaches is highlighted: every social decision rule that satisfies unanimity and a general principle of noninterference must be dictatorial. This raises some important issues for liberal approaches (...) in social choice and political philosophy. (shrink)

Several charters of rights have been issued in Europe to solemnly proclaim the rights of children during their hospital stay. However, notwithstanding such general declarations, the actual implementation of hospitalized children’s rights is unclear. The purpose of this study was to understand to which extent such rights, as established by the two main existing charters of rights, are actually implemented and respected in Italian pediatric hospitals and the pediatric units of Italian general hospitals, as perceived by the nurses working in (...) them.

En el presente artículo, exploramos diversos interrogantes relacionados con la construcción de las sexualidades mediáticas mapeando las formas en que los medios masivos de comunicación y las tecnologías de la información y la comunicación forman, conforman, crean, re-crean y reproducen las sexualidades hoy, comprendiendo que ninguna sexualización queda por fuera de la política y lo normado. Profundizamos en quiénes son seres sexuados en los medios masivos de comunicación (en adelante, MMC), quiénes tienen derecho a visibilizar su sexualidad y si existen (...) diferencias en la sexualización de mujeres y hombres, heterosexuales y homosexuales, personas blancas y negras. Igualmente, ahondamos en el análisis de la construcción de sí como ser sexual y sexuado a través de las redes sociales, reality shows y otros tipos de plataformas actuales, que desestabilizan las fronteras entre lo público y lo privado al cambiar los regímenes de visibilidad de sí y de los/as otros/as. Partiendo del análisis de contenido de los mensajes mediáticos, buscamos comprender e interpretar las sexualidades dominantes y reflexionar sobre los cuerpos sexuados marginados de los MMC. Igualmente, a partir del marco conceptual y de una sistematización de la legislación vigente en la región y en el mundo, proponemos formas de escapar de las nuevas formas de producción y reproducción de desigualdad.

A conjectural inference is proposed, aimed at producing conjectural theorems from formal conjectures assumed as axioms, as well as admitting contradictory statements as conjectural theorems. To this end, we employ Paraconsistent Informational Logic, which provides a formal setting where the notion of conjecture formulated by an epistemic agent can be defined. The paraconsistent systems on which conjectural deduction is based are sequent formulations of the C-systems presented in Carnielli-Marcos [CAR 02b]. Thus, conjectural deduction may also be considered to be a (...) tool for investigating the properties of paraconsistency in general. (shrink)

El objetivo de este documento es presentar una aproximación a las disertaciones desarrolladas en el contexto colombiano que abordan, en sus marcos de referencia, asuntos relacionados al enfoque socio político de la educación matemática, en la idea de identificar por donde ha transitado la comunidad en este tipo de ejercicios académicos. Para ello, se tuvieron en cuenta 61 disertaciones desarrolladas en el periodo 2011-2021, en tres universidades colombianas con reconocimiento por el desarrollo de trabajos académicos e investigativos en torno al (...) estudio del enfoque socio político. Metodológicamente la revisión de las disertaciones se hizo teniendo en cuenta las fases propuestas por Valero y Planas (2016). La revisión preliminar permitió identificar siete categorías: i) montaje de escenarios de aprendizaje desde la Educación Matemática Crítica —EMC—, ii) tensiones y obstáculos que vivencia el profesor cuando desarrolla prácticas pedagógicas; iii) procesos de evaluación desde prácticas sociales fundamentadas en la EMC; iv) estudio de asuntos teóricos diversos desde la EMC; v) ambientes de modelación matemática, desde perspectivas sociocríticas; vi) asuntos sobre la Etnomatemática y el giro decolonial; y vii) revisiones documentales. Circunstancia que nos permite reconocer abordajes investigativos desde enfoques socio políticos que se están desarrollando en las disertaciones. Identificando reflexiones sobre prácticas pedagógicas desde la creación de escenarios de aprendizaje o de ambientes de modelación matemática; reflexiones de carácter teórico sobre pensamiento crítico, formación en valores democráticos; relación entre el micro y macro contexto en clase de matemáticas; reconocimiento y estudio de las tensiones que experimenta el profesor cuando decide salir de su zona de confort. Si bien, se reconocen elementos desde los enfoques socio políticos que aún no han sido explorados, relacionados por ejemplo con cuestiones de raza, identidad, cuestiones de género y justicia social, entre otras; resulta importante resaltar el trabajo que se viene realizando en distintas universidades colombianas en la búsqueda de ahondar en investigaciones que vinculen las matemáticas con asuntos sociales, económicos, políticos y culturales desde un trabajo colaborativo entre escuela y universidad.

El objetivo de este trabajo es examinar el modo en que Kant concibe la relación entre el derecho político, el derecho de gentes y el derecho cosmopolita, en dos de sus textos de madurez: Hacia la paz perpetua y La metafísica de las costumbre s. El análisis de esta cuestión no solo permite esclarecer principios fundamentales de su filosofía jurídico-política, sino que aporta además nociones relevantes para la actual discusión acerca de los derechos humanos, el cosmopolitismo y el derecho internacional; (...) temáticas que posicionan a Kant como uno de los autores modernos de mayor presencia en el marco del debate filosófico contemporáneo. En primer lugar, examinaré la posición asumida por el filósofo con respecto al intervencionismo, que resulta especialmente relevante para comprender la relación entre el derecho político y el derecho de gentes, ya que obliga a pensar el alcance y los límites del principio de soberanía estatal. En segundo lugar, haré referencia al modo en que este autor concibe la conexión entre el republicanismo y la institución de una comunidad jurídica internacional, e intentaré mostrar que se trata aquí de fines independientes —y a la vez, vinculados— a los que debemos aproximarnos en un proceso de perfeccionamiento gradual de las instituciones jurídicas.

This paper provides an ethical intepretation of the Nash choice rule. In a setting in which (cardinal) utilities are interpersonally comparable, this procedure is characterised by an impartiality requirement and by the assumption that choices are not responsive to the agents' relative ability to convert resources into utility.

In recent years, contemplative practices of meditation have become increasingly mainstream in American culture, part of a phenomenon that scholars call “Buddhist modernism.” Connecting the embodied practice of meditation with the embodied practice of democracy in everyday life, this essay puts the radical democratic theory of Jacques Rancière into conversation with the Zen writings of Shunryu Suzuki and Thomas Merton. I show how meditation can be understood as an aesthetic practice that cultivates modes of experience, perception, thinking, and feeling that (...) further radical democratic projects at the most fundamental level. Reading the landscape of Buddhist modernism to draw out democratic possibilities, we can understand contemplative practices like meditation as a form of political theorizing in a vernacular register. Buddhist modernism works as a practice of everyday life that ordinary users can employ to get through their days with more awareness and attentiveness, to reclaim and reauthorize their experience, and to generate more care and compassion in ways that enable, enact, and extend the project of democracy itself.

While moral perfectionists rank conscious beings according to their cognitive abilities, Paola Cavalieri launches a more inclusive defense of all forms of subjectivity. In concert with Peter Singer, J. M. Coetzee, Harlan B. Miller, and other leading animal studies scholars, she expands our understanding of the nonhuman in such a way that the derogatory category of "the animal" becomes meaningless. In so doing, she presents a nonhierachical approach to ethics that better respects the value of the conscious self. Cavalieri (...) opens with a dialogue between two imagined philosophers, laying out her challenge to moral perfectionism and tracing its influence on our attitudes toward the "unworthy." She then follows with a roundtable "multilogue" which takes on the role of reason in ethics and the boundaries of moral status. Coetzee, Nobel Prize winner for Literature and author of _The Lives of Animals_, emphasizes the animality of human beings; Miller, a prominent analytic philosopher at Virginia Polytechnic Institute, dismantles the rationalizations of human bias; Cary Wolfe, professor of English at Rice University, advocates an active exposure to other worlds and beings; and Matthew Calarco, author of _Zoographies: The Question of the Animal from Heidegger to Derrida_, extends ethical consideration to entities that traditionally have little or no moral status, such as plants and ecosystems. As Peter Singer writes in his foreword, the implications of this conversation extend far beyond the issue of the moral status of animals. They "get to the heart of some important differences about how we should do philosophy, and how philosophy can relate to our everyday life." From the divergences between analytical and continental approaches to the relevance of posthumanist thinking in contemporary ethics, the psychology of speciesism, and the practical consequences of an antiperfectionist stance, _The Death of the Animal_ confronts issues that will concern anyone interested in a serious study of morality.

Cross-situational statistical learning of words involves tracking co-occurrences of auditory words and objects across time to infer word-referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words, but it remains unknown whether learners can encode fine phonological differences during cross-situational statistical learning. This study examined learners’ cross-situational statistical learning of minimal pairs that differed on one consonant segment, minimal pairs that differed on one vowel segment, and non-minimal pairs that differed on two (...) or three segments. Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non-minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word-referent co-occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.

Neste artigo, propõe-se uma leitura das categorias no tratado aristotélico homônimo como um primeiro esboço de uma ontologia regional, centrada nas substâncias sensíveis. Tendo por foco substância, quantidade, qualidade, relativo, agir e sofrer, este trabalho busca expor as duas estratégias principais que Aristóteles parece empregar para chegar a uma lista das categorias: (a) características básicas, cuja satisfação ou não satisfação de cada uma determina a natureza categorial de cada item e (b) a propriedade única que caracteriza cada categoria em contraste (...) com todas as outras. São, então, feitas considerações para vincular esse primeiro esboço ontológico a temas discutidos nos livros Lambda e Zeta da Metafísica, de modo a sugerir as direções principais que a sua ontologia nova (e geral) seguirá ao evoluir para uma teoria unificada da substância.

German philosopher and social critic Theodor Adorno (1903--1969) is widely regarded as one of the twentieth century's most influential thinkers. A leading member of the Frankfurt School, Adorno advanced an unconventional type of Marxist analysis in books such as Dialectic of Enlightenment (1944), Minima Moralia (1951), and Negative Dialectics (1966). Forced out of Nazi Germany because of his Jewish heritage, Adorno lived in exile in the United States for nearly fifteen years. In Adorno and Democracy, Shannon Mariotti explores how (...) this extended visit prompted a concern for and commitment to democracy that shaped the rest of his work. Mariotti analyzes the extensive and undervalued works Adorno composed in English for an American audience and traces the development of his political theory during the World War II era. Her unique study examines how Adorno changed his writing style while in the United States in order to directly address the public, which lay at the heart of his theoretical concerns. Despite his apparent contempt for popular culture, his work during this period clearly engages with a broader public in ways that reflect a deep desire to understand the problems and possibilities of democracy as enacted through the customs and habits of Americans. Ultimately, Adorno advances a theory of democratic leadership that works through pedagogy to cultivate a more robust and meaningful practice of citizenship. Mariotti incisively demonstrates how Adorno's unconventional and challenging interpretations of US culture can add conceptual rigor to political theory and remind Americans of the normative promise of democracy. Adorno and Democracy is an innovative contribution to critical debates about contemporary US politics. (shrink)

Accelerating environmental uncertainty and the need to cope with increasingly complex market and social demands, combine to create high value for the intuitive approach to decision-making at the strategic level. Research on intuition suffers from marked fragmentation, due to the existence of disciplinary silos based on diverse, apparently irreconcilable, ontological and epistemological assumptions. Not surprisingly, there is no integrated interdisciplinary framework suitable for a rich account of intuition, contemplating how affect and cognition intertwine in the intuitive process, and how intuition (...) scales up from the individual to collective decision-making. This study contributes to the construction of a broad conceptual framework, suitable for a multi-level account of intuition and for a fruitful dialogue with distant research areas. It critically discusses two mainstream conceptualizations of intuition which claim to be grounded in a cross-disciplinary consensus. Drawing on the complexity paradigm, it then proposes a conceptualization of intuition as emergence. Finally, it explores the theoretical and practical implications. (shrink)

Two of the most well-known belief contraction operators are partial meet contractions (PMCs) and kernel contractions (KCs). In this paper we propose two new classes of contraction operators, namely the class of generalized partial meet contractions (GPMC) and the class of generalized kernel contractions (GKC), which strictly contain the classes of PMCs and of KCs, respectively. We identify some extra conditions that can be added to the definitions of GPMCs and of GKCs, which give rise to some interesting subclasses of (...) those classes of functions, namely the classes of extensional and of uniform GPMCs/GKCs. In the context of contractions on belief sets the classes of partial meet contractions, uniform GPMCs and extensional GPMCs are all identical. Nevertheless, when considered as operations on belief bases, the class of uniform GPMCs coincides with the class of partial meet contractions, but the extensional GPMCs constitute a new kind of belief base contraction functions whose characterizing postulate of irrelevance of syntax is extensionality—the same postulate of irrelevance of syntax which occurs in the classical axiomatic characterization of partial meet contractions for belief sets—rather than the postulate of uniformity—which is the irrelevance of syntax postulate used in the axiomatic characterization for partial meet contractions on belief bases. Analogous results are obtained regarding the classes of extensional and of uniform GKCs. We present the interrelations in the sense of inclusion among all the new classes of operators presented in this paper and several well known classes of PMCs and of KCs. (shrink)

To contribute to our understanding of the relationship between philosophical ideas and medical and healthcare models. A diachronic analysis is put in place in order to evaluate, from an innovative perspective, the influence over the centuries on medical and healthcare models of two philosophical concepts, particularly relevant for health: how Man perceives his identity and how he relates to Nature. Five epochs are identified—the Archaic Age, Classical Antiquity, the Middle Ages, the Modern Age, the ‘Postmodern’ Era—which can be seen, à (...) la Foucault, as ‘fragments between philosophical fractures’. From a historical background perspective, up to the early 1900s progress in medical and healthcare models has moved on a par with the evolution of philosophical debate. Following the Second World War, the Health Service started a series of reforms, provoked by anti-positivistic philosophical transformations. The three main reforms carried out however failed and the medical establishment remained anchored to a mechanical, reductionist approach, perfectly in line with the bureaucratic stance of the administrators. In this context, future scenarios are delineated and an anthropo-ecological model is proposed to re-align philosophy, medicine and health care. (shrink)
