Symbolic arithmetic is fundamental to science, technology and economics, but its acquisition by children typically requires years of effort, instruction and drill1,2. When adults perform mental arithmetic, they activate nonsymbolic, approximate number representations3,4, and their performance suffers if this nonsymbolic system is impaired5. Nonsymbolic number representations also allow adults, children, and even infants to add or subtract pairs of dot arrays and to compare the resulting sum or difference to a third array, provided that only approximate accuracy is required6–10. Here (...) we report that young children, who have mastered verbal counting and are on the threshold of arithmetic instruction, can build on their nonsymbolic number system to perform symbolic addition and subtraction11–15. Children across a broad socio-economic spectrum solved symbolic problems involving approximate addition or subtraction of large numbers, both in a laboratory test and in a school setting. Aspects of symbolic arithmetic therefore lie within the reach of children who have learned no algorithms for manipulating numerical symbols. Our findings help to delimit the sources of children’s difficulties learning symbolic arithmetic, and they suggest ways to enhance children’s engagement with formal mathematics. We presented children with approximate symbolic arithmetic problems in a format that parallels previous tests of non-symbolic arithmetic in preschool children8,9. In the first experiment, five- to six-year-old children were given problems such as ‘‘If you had twenty-four stickers and I gave you twenty-seven more, would you have more or less than thirty-five stickers?’’. Children performed well above chance (65.0%, t1952.77, P 5 0.012) without resorting to guessing or comparison strategies that could serve as alternatives to arithmetic. Children who have been taught no symbolic arithmetic therefore have some ability to perform symbolic addition problems. The children’s performance nevertheless fell short of performance on non-symbolic arithmetic tasks using equivalent addition problems with numbers presented as arrays of dots and with the addition operation conveyed by successive motions of the dots into a box (71.3% correct, F1,345 4.26, P 5 0.047)8..

Can rational agents coordinate in simultaneous interactions? According to standard game theory they cannot, even if there is a uniquely best way of doing so. To solve this problem we propose an argument in favor of ‘belief-less reasoning’, a mode of inference that leads to converge on the optimal solution ignoring the beliefs of the other players. We argue that belief-less reasoning is supported by a commonsensical Principle of Relevant Information that every theory of rational decision must satisfy. We show (...) that this principle can be used to justify (some versions of) team reasoning, as well as other schemes of practical reasoning that do not involve sophisticated meta-representation.

Introduction The starting point is that ethical competence is the basis for ethical healthcare practices and quality of care. Simultaneously, there is a need for research and development from a holistic multi-professional perspective. Aim The aim is to create a proposed model for multi-professional ethical competence grounded in clarified meanings and dimensions of ethical competence studied from a multi-professional healthcare perspective. The research questions are, what is ethical competence from a multi-professional healthcare perspective and what strengthens a multi-professional ethical healthcare (...) practice? Research design The research has a qualitative approach and hermeneutic application research design. Two groups with six participants from clinical practice and two scientific researchers in each group met four times for dialogue. Thematic analysis was used as an analysis method. Ethical considerations The research is approved by the Declaration of Helsinki, the General Data Protection Regulations, and ethical permission was asked from the Norwegian Centre for Research Data (NSD). Results The proposed model for multi-professional ethical competence encompasses a three-dimensional ethical value base that is underpinned by: Ethical attitude – a personal desire to do good; Ethical basis – the best for the patient as a common goal and Ethical culture – common goals and values in the organization. Multi-professional ethical competence is strengthened by: Reflection – to see with new wondering eyes; Time for talk – interdisciplinary teamwork and Leadership – an ethical role model and support. Discussion Ethical competence has a strong link to the core of caring ethics and a deeper personal value base and attitude. Ethical competence involves the whole culture and is seen as a shared value base and a responsibility to do the best for the patient as a multi-professional team and organization. Ethical competence becomes active in healthcare practice by opening up for meaningful multi-professional talks and reflections. (shrink)

The last 20 years or so has seen an intense search carried out within Dempster–Shafer theory, with the aim of finding a generalization of the Shannon entropy for belief functions. In that time, there has also been much progress made in credal set theory—another generalization of the traditional Bayesian epistemic representation—albeit not in this particular area. In credal set theory, sets of probability functions are utilized to represent the epistemic state of rational agents instead of the single probability function of (...) traditional Bayesian theory. The Shannon entropy has been shown to uniquely capture certain highly intuitive properties of uncertainty, and can thus be considered a measure of that quantity. This article presents two measures developed with the purpose of generalizing the Shannon entropy for (1) unordered convex credal sets and (2) possibly non-convex credal sets ordered by second order probability, thereby providing uncertainty measures for such epistemic representations. There is also a comparison with the results of the measure AU developed within Dempster–Shafer theory in a few instances where unordered convex credal set theory and Dempster–Shafer theory overlap.

Uncertainty is, it seems, more or less constantly present in our lives. Even so, grasping the concept philosophically is far from trivial. In this doctoral thesis, uncertainty and its conceptual companion information are studied. Axiomatic analyses are provided and numerical measures suggested. In addition to these basic conceptual analyses, the widespread practice of so-called safety factor use in societal regulation is analyzed along with the interplay between science and policy in European regulation of chemicals and construction.

Recent years have seen a renewed interest in the philosophical study of information. In this paper a two-part analysis of information gain—objective and subjective—in the context of doxastic change is presented and discussed. Objective information gain is analyzed in terms of doxastic movement towards true belief, while subjective information gain is analyzed as an agent’s expectation value of her objective information gain for a given doxastic change. The resulting expression for subjective information gain turns out to be a familiar one (...) with well-known formal properties: the Kullback–Leibler divergence. The two notions of information are discussed and the suggested measure of subjective information gain is then compared with the widely held view that information gain equals uncertainty reduction.

Several hundred thousand intellectually talented 12-to 13-year-olds have been tested nationwide over the past 16 years with the mathematics and verbal sections of the Scholastic Aptitude Test (SAT). Although no sex differences in verbal ability have been found, there have been consistent sex differences favoring males in mathematical reasoning ability, as measured by the mathematics section of the SAT (SAT-M). These differences are most pronounced at the highest levels of mathematical reasoning, they are stable over time, and they are observed (...) in other countries as well. The sex difference in mathematical reasoning ability can predict subsequent sex differences in achievement in mathematics and science and is therefore of practical importance. To date a primarily environmental explanation for the difference in ability has not received support from the numerous studies conducted over many years by the staff of Study of Mathematically Precocious Youth (SMPY) and others. We have studied some of the classical environmental hypotheses: attitudes toward mathematics, perceived usefulness of mathematics, confidence, expectations/ encouragement from parents and others, sex-typing, and differential course-taking. In addition, several physiological correlates of extremely high mathematical reasoning ability have been identified (left-handedness, allergies, myopia, and perhaps bilateral representation of cognitive functions and prenatal hormonal exposure). It is therefore proposed that the sex difference in SAT-M scores among intellectually talented students, which may be related to greater male variability, results from both environmental and biological factors.

Este artículo estudia la visión que Ibn Hazm de Córdoba (m. 456 / 1064) tenía del concepto de fitra, que aparece en el Corán (azora XXX, aleya 30) y en algunas tradiciones exegéticas. Basándose en este texto, Ibn Hazm afirma que todos los seres humanos nacen musulmanes, incluso los idólatras y otras clases de infieles, y que todos han de ser considerados musulmanes hasta que alcancen la mayoría de edad. En ese momento de sus vidas han de elegir entre reafirmar (...) su fe y, si no son hijos de musulmanes, de elegir entre la religión en la que han nacido o renunciar a ella. Su decisión afectará a su destino en el Más Allá. La creencia de Ibn Hazm de que todos los niños son musulmanes hasta la edad en que puedan discernir y, por tanto, de que en caso de que mueran niños irán al Paraíso, tiene también implicaciones legales y, a través de ellas, se puede observar cómo actúan los principios zahiríes. Ibn Hazm muestra una tendencia a otorgar a los musulmanes la custodia de niños no musulmanes, así como a evitar que los nacidos musulmanes queden desvinculados de su religión. Este es el caso de los niños expósitos o cuya paternidad es dudosa. Aunque, en general, no requiere que los niños no musulmanes fallecidos, que en el fondo son considerados creyentes, sean enterrados de acuerdo con el rito islámico, ordena que un niño, cuyos padres no sean musulmanes y hayan sido hechos cautivos, reciba un entierro musulmán. Aunque, a primera vista, estas normas parezcan confirmar las afirmaciones de Goldziher sobre "el fananatismo personal contra los seguidores de otras religiones" de Ibn Hazm, se observa también que, según su punto de vista, la indemnización que se debía pagar por la lesión del feto de una mujer no musulmana era igual al que le correspondía a una musulmana que hubiese perdido su hijo en las mismas circunstancias.

In this article, we explore the organization of assistance in multilingual interaction in Swedish residential care. The data that form the basis for the study cover care encounters involving three residents with a language background other than Swedish, totalling 13 hours and 14 minutes of video documentation. The empirical data consists of a collection of 134 instances where residents seek assistance with the realization of a practical action. For this article, three examples that involve the manipulation of an object have (...) been selected for analysis. We use the concept of ‘recruitment’ to encompass the various methods by which assistance is sought in the care encounter. In the first example, the need for assistance concerns the transfer of an object that is recognizable and physically available for both participants. This, in combination with the resident’s gestural work that pinpoints the description of the action, facilitates its realization. In the second and third examples, the realization of the action becomes more difficult because the object involved is not recognizable for the caregiver. The article highlights the collaborative ways in which residents manage to support their talk through bodily practices, and the strong and empathetic engagement with which caregivers become involved in interpreting the meaning of these practices. Finally, we discuss the implications of our findings for care provision in multilingual circumstances. (shrink)

This study aims to analyze what drives and prevents the purchasing of eco-friendly products across different consumer groups and develops a conceptual model embracing the positive altruistic, positive ego-centric, and negative ego-centric antecedents of eco-friendly product purchase intention and behavior. We empirically validate the conceptual model for green and non-green consumers. Data are analyzed using structural equation modeling and multi-group analysis of the two groups. The results confirm the relevance of the determining factors in the model and show significant differences (...) in eco-friendly product purchasing patterns between green and non-green consumers. Altruistic motives are more important for green than for non-green consumers. Negative ego-centric motives affect the purchase intentions of non-green consumers more than the intentions of green consumers, whereas the impact of negative motives on behavior is stronger for green than for non-green consumers. The first contribution of this paper is the development and testing of a parsimonious model of eco-friendly products purchasing that embraces both positive and negative antecedents, which have been theoretically suggested in the past but have rarely been empirically tested together. The second contribution of this study is that it develops insight into the specific antecedents of eco-friendly products purchasing for green and non-green consumers to assess potential similarities and differences in eco-friendly products purchasing process, the hypothesized antecedents, their impact on eco-friendly products purchase intention and behavior, and the intention–behavior relation.

Recent work on workplace narratives as a site for the discursive construction of professional identities has focused on speakers who can be considered experienced and knowledgeable experts in their fields. The present study, in contrast, explores two types of workplace narratives — reflective and relational narratives — produced by a group of professionals who are non-experts: in this case, novice language teachers. Specifically, the article illustrates how the moral stance that a novice constructs within a narrative may be formulated in (...) uncertain terms, may be destabilized by the primary narrator, or may be subject to revision by other participants. Finally, the study highlights the relationship between the narrative dimensions of moral stance and tellership, and suggests that participant structure, participants' role relationships, and institutional power asymmetry are especially relevant factors to consider in any further analyses of novices' workplace narratives.

Este artículo discute las opiniones de Ibn Ḥazm de Córdoba jurista y teólogo, acerca de la homosexualidad. Aunque se hace referencia a su obra literaria Ṭawq al-ḥamāma, rica en anécdotas sobre atracción homoerótica, el artículo se centra en su voluminosa obra legal zahirí Kitāb al-Muḥallā y analiza el razonamiento legal de Ibn Ḥazm sobre la homosexualidad tanto masculina como femenina comparándola con la de otros juristas, en particular, malikíes.A diferencia de sus contemporáneos malikíes, Ibn Hazm mantiene que la homosexualidad no (...) debe equipararse a la fornicación que incurre en la pena de muerte. Por el contrario, aboga por el relativamente suave castigo de diez latigazos por prácticas homosexuales, basado en su interpretación de las fuentes reveladas tal y como se expone en este artículo.Aunque algunos autores modernos han insinuado que el propio Ibn Ḥazm era homosexual, él condena categóricamente las relaciones entre miembros de un mismo sexo y mantiene que los homosexuales deben reformarse.

For Friedrich Hölderlin, the mediatory role of aesthetics was central to overcoming the challenges of modern life, in particular human beings’ antagonistic relationship to nature. This article claims that Hölderlin preserves and improves what is true in Kant’s conception of the beautiful: that the experience of beauty concerns recognizing our dependence on nature, and that this recognition resonates in the works of artistic geniality as well. The article furthermore argues that the twentieth-century philosopher Theodor W. Adorno’s interpretation of Hölderlin sheds (...) light on how Hölderlin’s late poetry constitutes a remembrance of nature that avoids fetishizing nature as an origin to which we should return, while still allowing for an acknowledgment of its priority. Hölderlin’s poetry, as a work of spirit or mind, is exemplary in its commemoration of the precondition for spirit’s achievements: finite, empirical life. In this way, the self-reflectivity of Hölderlin’s poems also constitute a corrective to subjectivist tendencies that still reverberate in post-Kantian idealism. (shrink)

In most countries in the global north, social differences in health status and disease prevalence and outcomes are persistent and growing. This is also the case in the welfare states of Scandinavia. In Denmark, the empirical point of departure for this article, income inequality is relatively low and social mobility is generally considered to be high. One of the ideals of the Danish welfare state is that all citizens have free and open access to the tax-funded health-care system. All Danish (...) citizens can register at a general practice, which serves as the gatekeeper for more specialized health-care... (shrink)

Abstract What sense are we to make of the promise of love against the contingency of human life? I discuss two replies to this question: (1) the suggestion that marriage, based on the probable success of this kind of relationship, is a more or less worthwhile endeavour (cf. Moller and Landau), and (2) Martha Nussbaum's Aristotelian proposal that we only live life fully if we embrace aspects of life, such as loving relationships, that are vulnerable to fortune. I show that (...) both responses, in different ways, depend on the presupposition that the sense of our promises to love is dependent on our ability to make predictions. The philosophers I discuss assume an epistemological standpoint from which we may attempt to judge whether it is in our general interest to love. I argue that embracing such a perspective by itself leads our attention away from the kind of personal and moral engagement in other people of which our promises to love are expressive. From the perspective of love, the attempt to calculate the risks and gains of loving itself appears as a moral failure to be present to the reality of other people. (shrink)

One of the standard examples in contemporary moral psychology originates in the works of social psychologist Jonathan Haidt. He treats people's responses to the story of Julie and Mark, two siblings who decide to have casual, consensual, protected sex, as facts of human morality, providing evidence for his social intuitionist approach to moral judgements. We argue that Haidt's description of the facts of the story and the reactions of the respondents as ‘morally dumbfounded’ presupposes a view about moral reasoning that (...) is more substantial than he acknowledges. Drawing on the philosophical work by Iris Murdoch and Cora Diamond, we explore how different descriptions of human morality, sexuality, and family relations engage us in evaluations about distinctive features of human life and language that go deeper than Haidt envisages. Thus, we show the need to attend to the concepts used to describe the facts of human moral psychology and the pictures of morality these concepts reveal about the researcher's own understanding of moral experience. This points to the particular responsibility any researcher into human moral psychology has for ensuring that the descriptions they offer are attuned to the complexities of the lives of those they form theories about and that these do not appear conceptually confounding.

All effective communication is based on the participants trusting that they share their basic orientations to the world – that is, they have a common ground. In this paper, however, we examine situations in which such trust is lacking. Drawing on conversation–analytic methodology and on 30 hours of video data featuring persons with dementia and their caregivers in a Swedish-language daycare center in Finland, we consider some of the social consequences resulting from a lack of trust. Our analysis focused on (...) three different interactional contexts, highlighting the relevance of different facets of the participants’ common ground. These facets are anchored in the deontic, epistemic, and emotional orders, respectively. We show that, with regard to each order, a lack of trust in the existence of common ground has drastic consequences, leading to problems related to getting one’s will acknowledged, a scarcity of conversational partners, and a lack of resources to maintain affection.

During evaluative conditioning, a neutral conditional stimulus becomes pleasant or unpleasant after pairings with a positive/negative unconditional stimulus. Measures of US expectancy are...

Negative conditional stimulus valence acquired during fear conditioning may enhance fear relapse and is difficult to remove as it extinguishes slowly and does not respond to the instruction that unconditional stimulus presentations will cease. We examined whether instructions targeting CS valence would be more effective. In Experiment 1, an image of one person was paired with an aversive US, while another was presented alone. After acquisition, participants were given positive information about the CS+ poser and negative information about the CS− (...) poser. Instructions reversed the pattern of differential CS valence present during acquisition and eliminated differential electrodermal responding. In Experiment 2, we compared positive and negative CS revaluation by providing positive/negative information about the CS+ and neutral information about CS−. After positive revaluation, differential valence was removed and differential electrodermal responding remained intact. After negative revaluation, differential valence was strengthened and differential electrodermal responding was eliminated. Unexpectedly, the instructions did not affect the reinstatement of differential electrodermal responding. (shrink)

In order to articulate an account of erotic love that does not attempt to transcend its personal features, Robert Solomon and Martha Nussbaum lean on the speeches by Aristophanes and Alcibiades in Plato’s Symposium. This leads them to downplay the sense in which love is not only for another person, but also for the good. Drawing on a distinction between relative and absolute senses of speaking about the good, I mediate between two features of love that at first may seem (...) irreconcilable. The first is the sense in which love is deeply personal in character. The second is the sense in which we in love come to articulate ethical demands. With the help of the Diotimian ascent of love that Socrates presents in his speech, I submit that these two can come together in the realization that our personally conditioned responses in love are transformed to accommodate demands that carry an unconditional meaning.

Does one’s love for a particular person, when it is pure, also constitute a love of life? The significance of speaking about leading a passionate life, I submit, is found in the spontaneous, embodied character of opening up to and finding meaning in one’s life rather than in heightened fleeting feelings or experiences of meaning that help one forget life’s meaninglessness. I contrast this view with Simone Weil’s suspicion that our passionate attachment to another person is an obstacle to attending (...) to him or her from the distance proper to love and friendship. From that perspective it appears as if the meaning with which personal love endows life is mostly illusory, including the loss of meaning characteristic of grief. I question whether Weil’s view should be seen as an unconditional, though for most unattainable, ideal of love, or if it is rather expressive of a rejection of one of the central features of love: the vulnerability that ensues from the recognition that when we love there are times where we stand in need of the other’s love to be able to embrace life as meaningful.

Skilled handwriting of single letters is associated not only with a neat final product but also with fluent pen-movement, characterized by a smooth pen-tip velocity profile. Our study explored fluency when writing single letters in children who were just beginning to learn to handwrite, and the extent to which this was predicted by the children’s pen-control ability and by their letter knowledge. 176 Norwegian children formed letters by copying and from dictation. Performance on these tasks was assessed in terms of (...) the counts of velocity inversions as the children produced sub-letter features that would be produced by competent handwriters as a single, smooth action. We found that there was considerable variation in these measures across writers, even when producing well-formed letters. Children also copied unfamiliar symbols, completed various pen-control tasks, and tasks that assessed knowledge of letter sounds and shapes. After controlling for pen-control ability, pen-movement fluency was affected by letter knowledge. This was the case when children retrieved letter forms from dictated letter sounds, but also when directly copying letters and, unexpectedly, when copying unfamiliar symbols. These findings suggest that familiarity with a letter affects movement fluency during letter production but may also point towards a more general ability to process new letter-like symbols in children with good letter knowledge.

The understanding of the meaning of Jewish identity in Clement Greenberg's work follows the deep relationship between the conception of Modernism and the interpretation of Franz Kafka's short story The Great Wall of China. Greenberg, whose role as one of the first american popularizers of Kafka's narratives has been relevant, ascribes to the bohemian author an halachic reasoning closely related to his jewish origins. This strictly firm and normative mindset finds resemblances in Greenberg's modernist theory and critical practice, which, according (...) to Susan Noyes-Platt's study, could be interpreted as a derivation, in many aspects, of his Jewish origins and, particularly, as the critic's need to preserve his intellectual thinking from the nazi-fascist advance. Moreover, the article proposes to interpret Greenberg's purism as a form of messianism, that is a faith in a future, but indefinitely belated, absolute purification of the medium. (shrink)
