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..

Este artículo estudia la visión que Ibn Ḥazm de Córdoba tenía del concepto de fiṭra, que aparece en el Corán y en algunas tradiciones exegéticas. Basándose en este texto, Ibn Ḥazm 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 Ḥazm 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 Ẓāhiríes. Ibn Ḥazm 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. Ese 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 fanatismo personal contra los seguidores de otras religiones» de Ibn Ḥazm, 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.

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)

This is the first book to unpack the legal and ethical issues surrounding unauthorised intimate examinations during labour. The book uses feminist, socio-legal and philosophical tools to explore the issues of power, vulnerability and autonomy. The collection challenges the perception that the law adequately addresses different manifestations of unauthorised medical touch through the lens of women's experiences of unauthorised vaginal examinations during labour. The book unearths several broader themes that are of huge significance to lawyers and healthcare professionals such as (...) the legal status of women and their bodies. The book raises questions about women's experiences during childbirth in hospital settings. It explores the status of women's bodies during labour and childbirth where too easily they become objectified, and it raises important issues around consent. The book highlights links to the law on sexual offences and women's loss of power under the medical gaze. The book includes contributions from leading feminist philosophers, medical professionals, and academics in medicine and law, and offers pioneering analysis relevant to lawyers and healthcare professionals with an interest in medical law and ethics; feminist theory; criminal law; tort law; and human rights law.

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.

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.

In 1906, Frigyes Riesz introduced a preliminary version of the notion of a topological space. He called it a mathematical continuum. This development can be traced back to the end of 1904 when, genuinely interested in taking up Hilbert’s foundations of geometry from 1902, Riesz aimed to extend Hilbert’s notion of a two-dimensional manifold to the three-dimensional case. Starting with the plane as an abstract point-set, Hilbert had postulated the existence of a system of neighbourhoods, thereby introducing the notion of (...) an accumulation point for the point-sets of the plane. Inspired by Hilbert’s technical approach, as well as by recent developments in analysis and point-set topology in France, Riesz defined the concept of a mathematical continuum as an abstract set provided with a notion of an accumulation point. In addition, he developed further elementary concepts in abstract point-set topology. Taking an abstract topological approach, he formulated a concept of three-dimensional continuous space that resembles the modern concept of a three-dimensional topological manifold. In 1908, Riesz presented his concept of mathematical continuum at the International Congress of Mathematicians in Rome. His lecture immediately won the attention of people interested in carrying on his research. They promoted his ideas, thus assuring their gradual reception by several future founders of general topology. In this way, Riesz’s work contributed significantly to the emergence of this discipline.

As I move through the garden, something, a strange species of writing, hovers before me like the perfume of a wild rose. I read the words: Metaphor is a plant. That is to say, plants are metaphors for metaphor. This message, then, this vegetal missive, appears to be constituted by a kind of phyto- or antho-morphism, reading by way of a metaphorical vegetal life. But as I continue to write, as I ‘extend’ myself, as Derrida does, ‘by force of play’, (...) I find that this, in the end, will have been an extended metaphor. (shrink)

Reindeer meat, traditional food and knowledge are vital for the culture, health, and economy of Sámi reindeer herders. Nevertheless, the practices of reindeer meat smoking have barely been part of scientific research or reindeer herding management. We investigated Sámi reindeer herders’ approach to meat smoking in Northern Norway performed in the traditional Sámi tent, the lávvu. The investigation included workshops, interviews, participatory observations, and co-analyze meetings. Our findings reveal a typology of the traditional Sámi smoking practices. Sámi reindeer herders use (...) a variety of wood species and plant parts to control the smoke based on a complex system of traditional knowledge. Yet there is a need for education, industry, and research acknowledging, supporting, and maintaining the Sámi meat-smoking process and associated worldviews, knowledge, and practices to ensure ethical, sustainable, and healthy food production.

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.

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)

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)

What is it to share the same concept? The question is an important one since sharing the same concept explains our ability to non-accidentally coordinate on the same topic over time and between individuals. Moreover, concept identity grounds key logical relations among thought contents such as samesaying, contradiction, validity, and entailment. Finally, an account of concept identity is crucial to explaining and justifying epistemic efforts to better understand the precise contents of our thoughts. The key question, then, is what psychological (...) and social facts could play these roles? Elsewhere, we have argued for a specific relational model of concept identity, the connectedness model (e.g. Schroeter 2012, Schroeter and Schroeter 2014, 2015). Our aim in this chapter is to further explain the motivations behind that account, to address worries about transitivity and vagueness, and to contrast our approach with closely related accounts of concept identity developed by François Recanati and Simon Prosser. -/- What’s distinctive of our approach is that we seek to vindicate the first-person epistemic perspective of concept users. Concepts, on our account, play a crucial normative role in setting regulative ideals for the representational practices in which individual subjects participate. This focus on the normative role of concepts – as opposed to a purely causal explanatory role – motivates our approach to concept identity and our toleration of vagueness and borderline cases.

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.

Questa ricerca, attraverso alcune letture incrociate di Michel Foucault e di Claude Lévi-Strauss, mette in luce l’attualità di due grandi pensatori che pongono al centro delle loro teorie il tema della distanza, dell’altro da sé e del ritorno a sé per comprendere il ruolo del soggetto nella civiltà occidentale. Al di là delle rilevanti differenze che li contraddistinguono, Foucault e Lévi-Strauss percorrono due cammini teorici volti a decostruire il rapporto tra verità e soggetto nella civiltà occidentale adottando una prospettiva della (...) distanza e dell’allontanamento da sé, quali tecniche per comprendere se stessi. Da una parte il concetto foucaultiano di eterotopia, in quanto «spazio assolutamente altro», permette di comprendere i meccanismi attraverso i quali ci si proietta in un altrove senza luogo preciso per localizzare se stessi. Il campo dell’etnologia, sarà dunque letto attraverso la lente foucaultiana, quale «eterotopologia», o scienza eterotopica, per eccellenza. Dall’altra, questo concetto sarà analizzato alla luce di quello che Lévi-Strauss ha definito nel saggio sui Tre umanesimi una «tecnica dello straniamento», ovvero un metodo che permette di pensare se stessi grazie al confronto con l’Altro, con culture di altri luoghi ed altri tempi: per conoscere il soggetto che è l’uomo, non si può non prescindere da un lavoro di continui raffronti e paragoni tra diverse società nel tempo e nello spazio.

The potential to collect brain data more directly, with higher resolution, and in greater amounts has heightened worries about mental and brain privacy. In order to manage the risks to individuals posed by these privacy challenges, some have suggested codifying new privacy rights, including a right to “mental privacy.” In this paper, we consider these arguments and conclude that while neurotechnologies do raise significant privacy concerns, such concerns are—at least for now—no different from those raised by other well-understood data collection (...) technologies, such as gene sequencing tools and online surveillance. To better understand the privacy stakes of brain data, we suggest the use of a conceptual framework from information ethics, Helen Nissenbaum’s “contextual integrity” theory. To illustrate the importance of context, we examine neurotechnologies and the information flows they produce in three familiar contexts—healthcare and medical research, criminal justice, and consumer marketing. We argue that by emphasizing what is distinct about brain privacy issues, rather than what they share with other data privacy concerns, risks weakening broader efforts to enact more robust privacy law and policy.

Why is there a felt asymmetry between cases in which agents defer to testifiers for certain moral beliefs, and cases in which agents defer on many other matters? One explanation influential in the literature is that having understanding of a proposition is both in tension with acquiring belief in the proposition by deferring to another's testimony and distinctively important when it comes to moral propositions, as compared with what we might think of as many ‘garden variety’ facts. My project in (...) this paper is to offer a new and more defensible version of this explanation. This will involve re-conceiving understanding as a richer state than it is commonly thought to be, requiring affective and motivational engagement with reasons as well as cognitive facility. I also offer a new explanation of the tension between understanding and deference to testimony. (shrink)

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.

This article deals with the concept of vulnerability in social work and how social work students understand the concept of professionalism. The article is based on an empirical study of social worker students and on analysis of the literature used in the education. Theoretically, the article rests upon vulnerability theory as elaborated by Martha Fineman. The analysis suggests that the social worker students share an understanding of the client as vulnerable, and of the social worker as not vulnerable. This entails (...) a view that the social worker is objective and somewhat distanced from his/her clients. The article argues that this understanding runs the risk of producing non-reflexive social work practitioners that are not aware of their own vulnerable position. In conclusion, we state that an understanding of professionalism centred on a shared vulnerability of all beings could bridge the often-used dichotomous understanding of the social worker as either “helper” or “authoritative bureaucrat” and thus lead to a more resilient concept of professionalism.

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)

In this comprehensive new study of human free agency, Laura Waddell Ekstrom critically surveys contemporary philosophical literature and provides a novel account of the conditions for free action. Ekstrom argues that incompatibilism concerning free will and causal determinism is true and thus the right account of the nature of free action must be indeterminist in nature. She examines a variety of libertarian approaches, ultimately defending an account relying on indeterministic causation among events and appealing to agent causation only in (...) a reducible sense. Written in an engaging style and incorporating recent scholarship, this study is critical reading for scholars and students interested in the topics of motivation, causation, responsibility, and freedom. In broadly covering the important positions of others along with its exposition of the author’s own view, Free Will provides both a significant scholarly contribution and a valuable text for courses in metaphysics and action theory.

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.
