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..

This volume represents the state of the art in research on the controversial Muslim legal scholar, theologian and man of letters Ibn azm of Cordoba (d. 456/1064), who is widely regarded as one of the most brilliant minds of Islamic Spain.

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.

The cries of Lamentations are desperate, wailing up from the darkest side of human existence. They will not be silenced. Lament harasses those who oppress and calls all to justice—even God.

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.

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.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.3 (2003) 426-427 [Access article in PDF] Timothy Smiley, editor. Mathematics and Necessity: Essays in the History of Philosophy. New York: Oxford University Press, 2000. Pp. ix + 166. Cloth, $35.00.Mathematics and Necessity contains essays by M. F. Burnyeat, Ian Hacking, and Jonathan Bennett based on lectures given to the British Academy in 1998. All concern the history of the philosophical treatment of (...) mathematics, necessity, or both, although there is no single thread running through all three essays.Burnyeat focuses on Plato's understanding of mathematics in the Republic, making use of the Timeaus in particular to defend his interpretation. Plato claimed that in the ideal society mathematics should be studied for a full ten years, which many have thought excessive. To explain it, Burnyeat argues that the role of mathematics is pervasive: ethics and politics are mathematical, because in Plato's view mathematics is a constitutive part of ethical understanding. On Burnyeat's interpretation, goodness is part of the objective world, and mathematics is a science of values. The link between mathematics and goodness in the objective world is forged by the concord, harmony, and unity of proportions, which express the goodness of the Divine Craftsman's beneficent design. Proportions are both intrinsically good and the proper study of mathematics.Burnyeat explains why Plato thinks abstract kinematics (the pure non-sensible counterpart to astronomy) and abstract harmonics lead to knowledge of the good. Abstract kinematics concerns the "harmony of the spheres" described in the Republic. Drawing heavily on the Timeaus, Burnyeat argues that the circular motions of the spheres are motions in the intelligence of the world soul and that there are similar motions in human souls. The world soul and human souls are spatial and have circular motions (invisibility and intangibility make them incorporeal). Souls are the most important subject matter of abstract harmonics—the study of good proportions. A soul that understands the various mathematical disciplines and their relations takes on the harmony and hence goodness of the world soul. Such a soul serves as a model for organizing the social world, a model which properly trained rulers can use to shape a community. Burnyeat's well-argued essay is compelling and exciting. [End Page 427]Ian Hacking's views provide a great contrast to Burnyeat's Plato. Hacking conducts a phenomenological inquiry into why some philosophers have become obsessed by mathematics as a source of philosophical inspiration. He holds that mathematics concerns a relatively minor part of human culture and that the influence of mathematics on philosophy is pernicious; he even describes it as an infection.Hacking examines the views of six philosophers: Plato, Leibniz, Mill, Descartes, Lakatos, and Wittgenstein. Hacking's assessment of the six philosophers is at times disputable, but it is also interesting and stimulating, and serves his phenomenological inquiry.Hacking traces philosophy's infection by mathematics to two factors. A mathematical proof can be perspicuous; that is, a proof can be "grasped," which requires seeing directly why something must be true and being able to recapitulate it. A mathematical proof can also anticipate facts about the world. He thinks that these two factors affect us in two ways: they give us the idea of a priori knowledge, and they dazzle us into unreasoned conviction in proofs. One might respond that, setting aside the feeling proofs give us, we are still justified in being impressed by them. Hacking argues that much of what impresses is based on a misunderstanding of their nature, which he attempts to correct.According to Hacking, a mathematical demonstration involves shifts of meaning that analytically bind the proof and the theorem it establishes. They thereby mutually support each other and provide what he calls self-authentication. The correctness of the proof is supported by the "analytified" truth of the theorem and the theorem is considered true because proven.This bootstrapping feature of mathematical proofs supports Hacking's deflationary account of necessity. Hacking suggests that the "must" of logical necessity rests upon our unwillingness to accept empirical counter-examples to the... (shrink)

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 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.

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)

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.

Engaging with the philosophical writings of Iris Murdoch, we submit that there are difficulties associated with providing a good description of morality that are intimately connected with difficulties in understanding other human beings. We suggest three senses in which moral philosophical reflection needs to account for our understanding of others: (1) the failure to understand someone is not merely an intellectual failure, but also engages us morally; (2) the moral question of understanding is not limited to the extent to which (...) we understand a particular person, but also presents itself in how we picture difficulties in understanding people; and (3) “philosophical pictures of morality” fundamentally shape the conceptual framework we use to investigate morality, as well as the analysis of morality we find illuminative and satisfactory. Exploring the implications of these claims, we ask what it means to think of others as the same, or as different, from ourselves. We then consider the ethical significance of finding, or not finding, our feet in our encounters with others, dwelling on how the metaphor of movement reveals one way in which we are never at peace in the exploration of morality.

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.

Dieser Band lotet vor dem Hintergrund einer krisenhaften Gegenwart das Verhältnis von Verletzbarkeit und Institutionen aus. Im Fokus stehen dabei die Fragen, wie Dimensionen der Verletzbarkeit durch Anrufungen und soziale, politische, kulturelle Praktiken (doing vulnerability) institutionell hergestellt und perpetuiert werden, in welchen Bedeutungszusammenhängen sie verankert und verstetigt sind und wie Anrufungen der Verletzbarkeit schließlich auch provoziert und subvertiert werden können. Institutionen werden dabei nicht als homogene Gebilde, sondern als Bündelung von Kräften verstanden, die es immer wieder neu zu entwerfen, zu (...) imaginieren, zu erstreiten und zu verteidigen gilt.

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.

The notion that eukaryotes are ancestrally sexual has been gaining attention. This idea comes in part from the discovery of sets of “meiosis‐specific genes” in the genomes of protists. The existence of these genes has persuaded many that these organisms may be engaging in sex, even though this has gone undetected. The involvement of sex in protists is supported by the view that asexual reproduction results in the accumulation of mutations that would inevitably result in the decline and extinction of (...) such lineages. It is argued that this phenomenon can be obviated by polyploidy and that the “meiosis‐specific genes” are used in other processes, including polyploidy control and homologous recombination, independent of meiosis. These phenomena account for the finding that these genes are expressed in cultures devoid of apparent cell fusion events. Hence, it is also proposed that asexual, and not sexual, reproduction is the ancestral condition. (shrink)

Eyewitnesses to crimes sometimes search for a culprit on social media before viewing a police lineup, but it is not known whether this affects subsequent lineup identification accuracy. The present online study was conducted to address this. Two hundred and eighty-five participants viewed a mock crime video, and after a 15–20 min delay either viewed a mock social media site including the culprit, viewed a mock social media site including a lookalike, or completed a filler task. A week later, participants (...) made an identification from a photo lineup. It was predicted that searching for a culprit on social media containing the lookalike would reduce lineup identification accuracy. There was a significant association between social media exposure and lineup accuracy for the Target Present lineup, but for the Target Absent lineup there was no significant association with lineup identification accuracy. The results suggest that if an eyewitness sees a lookalike when conducting a self-directed search on social media, they are less likely to subsequently identify the culprit in the formal ID procedure.

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.
