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..

ObjectiveOverweight and obesity [body mass index ≥ 25 kg/m2] are associated with poorer prognosis among women with breast cancer, and weight gain is common during treatment. Symptoms of depression and anxiety are also highly prevalent in women with breast cancer and may be exacerbated by post-diagnosis weight gain. Altered brain function may underlie psychological distress. Thus, this secondary analysis examined the relationship between BMI, psychological health, and resting state functional connectivity among women with breast cancer.MethodsThe sample included 34 post-menopausal women (...) newly diagnosed with Stage 0-IIa breast cancer who were enrolled in a 6-month randomized controlled trial of aerobic exercise vs. usual care. At baseline prior to randomization, whole-brain analyses were conducted to evaluate the relationship between BMI and seed-to-voxel rsFC of the hippocampus and amygdala. Connectivity values from significant clusters were then extracted and examined as predictors of self-reported depression and anxiety.ResultsMean BMI was in the obese range. For both seeds examined, higher BMI was associated with lower rsFC with regions of prefrontal cortex, including ventrolateral PFC, dorsolateral PFC, and superior frontal gyrus. Hippocampal connectivity with the vlPFC was negatively correlated with self-reported anxiety.ConclusionHigher BMI was associated with lower hippocampal and amygdala connectivity to regions of PFC implicated in cognitive control and emotion regulation. BMI-related differences in hippocampal and amygdala connectivity following a recent breast cancer diagnosis may relate to future worsening of psychological functioning during treatment and remission. Additional longitudinal research exploring this hypothesis is warranted. (shrink)

According to what Barry Dainton calls the 'Strong Introspectibility thesis', it is a necessary truth that mental states S and S* are co-conscious (experienced together) if and only if they are 'jointly introspectible', i.e., if and only if it is possible for there to be some single state of introspective awareness that represents both S and S*. Dainton offers two arguments for the conclusion that joint introspectibility is unnecessary for co-consciousness. In these comments I attempt to show, first, that Dainton's (...) arguments fail, and, second, that joint introspectibility is actually insufficient for co-consciousness. (As to whether it is also unnecessary, I take no stance.). (shrink)

It is a commonplace now among art historians that to say, with Ruskin, that an artist had an "innocent eye" was to give the artist an empty compliment. It would have been to say that the artist possessed something no one could possess, and that, if we follow E. H. Gombrich, the artist was not part of the history of art. Gombrich's goal was to show that the history of art was constituted by artists "making and matching" as they saw (...) and represented more accurately the objects with which their predecessors were only dimly acquainted. So an artist with an "innocent eye" would stand outside of history, or at least outside of history as Gombrich tells it; the artist's work being irrreconcilable with the works that flanked it before and after.

A dynamical analysis of standard procedures for subensemble selection is used to show that the state restriction violation proposal in Part I of the paper cannot be realized by employing familiar correlation schemes. However, it is shown that measurement of an observable not commuting with the superselection operator is possible, a violation of the observable restrictions. This is interpreted as supporting the position that each of these restrictions is sufficient but not necessary for the superselection rule. The results do constitute (...) a proposal for superselection rule violation in theories requiring both restrictions, e.g., the axiomatic treatment by Bogolubov, Logunov, and Todorov. It is also concluded that superselection rules place restrictions on procedures for selective state preparations using correlations. More generally, it is conjectured that a mathematically conceivable decomposition of a given density operator does not necessarily represent a possibility for partitioning of the corresponding ensemble into subensembles by any physically realizable means.

In the influential 1995 article “Social Conditions as Fundamental Causes of Disease,” Bruce Link and Jo Phelan described social and political factors as “fundamental causes” of death and disease. Whitney Pirtle has recently declared racial capitalism another such fundamental cause. Using the case of the water crisis in Flint, Michigan, she has argued that racial capitalism's role in that situation meets each of the criteria Link and Phelan's article outlines: racial capitalism influenced multiple disease outcomes, affected disease outcomes through multiple (...) risk factors, involved access to flexible resources that can be used to minimize both risks and the consequences of disease, and was reproduced over time through the continual replacement of intervening mechanisms. We argue for Pirtle's conclusion using the extensive literature on racial capitalism and case studies concerning housing in the United States and Brazil and what Naomi Klein has termed “corona capitalism” in India. If races correspond to hierarchies of material security, as suggested by Ruth Wilson Gilmore, then these hierarchies and their causal effects are fundamental determinants of public health. (shrink)

I formulate an account, in terms of essence and ground, that explains why atomic Russellian propositions have the truth conditions they do. The key ideas are that (i) atomic propositions are just 0-adic relations, (ii) truth is just the 1-adic version of the instantiation (or, as I will say, holding) relation (Menzel 1993: 86, note 27), and (iii) atomic propositions have the truth conditions they do for basically the same reasons that partially plugged relations, like being an x and a (...) y such that Philip gave x to y, have the holding conditions they do. The account is meant to be mainly of intrinsic interest, but I hope that it goes some distance toward answering an objection to classical theories of propositions put forward by King (2014), who writes that ‘since the classical conception of propositions as things that have truth conditions by their very natures and independently of minds and languages is incapable of explaining how or why propositions have truth conditions, it is unacceptable’ (2014: 47). Propositions do have their truth conditions ‘by their very natures’ and ‘independently of minds and languages’. But a fact about a given entity can hold by the very nature of that entity without being a fundamental fact. I argue that this is plausibly the case for atomic Russellian propositions and the facts about their truth conditions. A fact about the truth conditions of such a proposition holds by the very nature of the given proposition but is metaphysically grounded in facts about that proposition’s parts and their essences. If my account is correct, then the supposedly intractable problem of explaining why the given propositions have the truth conditions they do reduces to the problem of explaining why relations have the holding essences they do, which few seem to have found worrisome .

David Lewis defends the following "non-circular definition of personhood": "something is a continuant person if and only if it is a maximal R-interrelated aggregate of person-stages. That is: if and only if it is an aggregate of person-stages, each of which is R-related to all the rest (and to itself), and it is a proper part of no other such aggregate." I give a counterexample, involving a person who is a part of another, much larger person, with a separate mental (...) life. I then offer an easy repair, which preserves the virtues of Lewis's definition without introducing any new vices. (shrink)

The so-called Final Ranking of the Philebus offers Socrates’ final evaluation of the relative merits of pleasure and reason in the best life. I begin by examining two common lines of interpretation as they address the criterion according to which the final ranking is organized. I then discuss the role ‘similarity’ has in organizing the investigation throughout the dialogue, from the initial comparison of the two lives (of reason and pleasure singly) down through the final ranking. I then consider the (...) thematic discussions of pleasure and reason separately, arguing that their treatments display an intriguing structural similarity. Next, I propose my own reading of the final ranking, whereby the ‘dependence’ relation at work in those two specific discussions may be see as the through-line of all (now five) tiers of the final ranking. I conclude by suggesting that this interpretation is able to preserve what is worthwhile in the two traditional lines of interpretation, while avoiding the pitfalls that tend to accompany them.

In learning mathematics, children must master fundamental logical relationships, including the inverse relationship between addition and subtraction. At the start of elementary school, children lack generalized understanding of this relationship in the context of exact arithmetic problems: they fail to judge, for example, that 12 + 9 - 9 yields 12. Here, we investigate whether preschool children’s approximate number knowledge nevertheless supports understanding of this relationship. Five-year-old children were more accurate on approximate large-number arithmetic problems that involved an inverse transformation (...) than those that did not, when problems were presented in either non-symbolic or symbolic form. In contrast they showed no advantage for problems involving an inverse transformation when exact arithmetic was involved. Prior to formal schooling, children therefore show generalized understanding of at least one logical principle of arithmetic. The teaching of mathematics may be enhanced by building on this understanding. (shrink)

Comprised of 45 chapters, written especially for this volume by an international team of leading experts, The Routledge Companion to the Philosophies of Painting and Sculpture is the first handbook of its kind. The editors have organized the chapters helpfully across eight parts: I: Artforms II: History III: Questions of Form, Style, and Address IV: Art and Science V: Comparisons among the Arts VI: Questions of Value VII: Philosophers of Art VIII: Institutional Questions Individual topics include art and cognitive science, (...) evolutionary origins of art, art and perception, pictorial realism, artistic taste, style, issues of race and gender, art and religion, art and philosophy, and the end of art. The work of selected philosophers is also discussed, including Diderot, Hegel, Ruskin, Gombrich, Goodman, Wollheim, and Danto. With a volume introduction from the editors and comprehensively indexed, The Routledge Companion to the Philosophies of Painting and Sculpture serves as a point of entry to the subject for a broad range of students as well as an up-to-date reference for scholars in the field.

A medical information commons is a networked data environment utilized for research and clinical applications. At three deliberations across the U.S., we engaged 75 adults in two-day facilitated discussions on the ethical and social issues inherent to sharing data with an MIC. Deliberants made recommendations regarding opt-in consent, transparent data policies, public representation on MIC governing boards, and strict data security and privacy protection. Community engagement is critical to earning the public's trust.

I am grateful to Catharine Abell and Gregory Currie for their incisive and productive commentaries on Apt Imaginings. In what follows, I will try to respond to.

Speaks defends the view that propositions are properties: for example, the proposition that grass is green is the property being such that grass is green. We argue that there is no reason to prefer Speaks's theory to analogous but competing theories that identify propositions with, say, 2-adic relations. This style of argument has recently been deployed by many, including Moore and King, against the view that propositions are n-tuples, and by Caplan and Tillman against King's view that propositions are facts (...) of a special sort. We offer our argument as an objection to the view that propositions are unsaturated relations. (shrink)

We explore and critically reflect on the process of science and engineering research assistant skill development both within laboratory-based research teams and, when no team is present, within the faculty supervisor-research assistant interactions. Using a performance-based measure of research skill development, we identify research assistants who, over the course of an academic year of service as a researcher, markedly developed, modestly developed, or failed to develop their research skills. Interviews with these research assistants and their faculty supervisors, seen through the (...) lens of cognitive apprenticeship, provide insight into this variation. We found that within the contours of supervisory relationships and research teams, research skill development is indelibly shaped, for better or worse, by supervisor influence and abundant trial-and-error.

Relativity theory is often said to support something called ‘the four-dimensional view of reality’. But there are at least three different views that sometimes go by this name. One is ‘spacetime unitism’, according to which there is a spacetime manifold, and if there are such things as points of space or instants of time, these are just spacetime regions of different sorts: thus space and time are not separate manifolds. A second is the B-theory of time, according to which the (...) past, present, and future are all equally real and there is nothing metaphysically special about the present. A third is perdurantism, according to which persisting material objects are made up of different temporal parts located at different times. We sketch routes from relativity to unitism and to the B-theory. We then discuss some routes to perdurantism, via the B-theory and via unitism. (shrink)

Nonsymbolic comparison tasks are commonly used to index the acuity of an individual's Approximate Number System (ANS), a cognitive mechanism believed to be involved in the development of number skills. Here we asked whether the time that an individual spends observing numerical stimuli influences the precision of the resultant ANS representations. Contrary to standard computational models of the ANS, we found that the longer the stimulus was displayed, the more precise was the resultant representation. We propose an adaptation of the (...) standard model, and suggest that this finding has significant methodological implications for numerical cognition research. (shrink)

Do Russellian propositions have their constituents as parts? One reason for thinking not is that if they did, they would generate apparent counterexamples to plausible mereological principles. As Frege noted, they would be in tension with the transitivity of parthood. A certain small rock is a part of Etna but not of the proposition that Etna is higher than Vesuvius. So, if Etna were a part of the given proposition, parthood would fail to be transitive. As William Bynoe has noted (...) (speaking of facts rather than propositions), they would seem to violate certain supplementation principles. Consider the singular proposition, concerning identity, that it is identical with itself. Given the relevant form of Russellianism, this proposition would have identity as a proper part, but it would not have any parts disjoint from identity, and indeed it would not have even a single pair of disjoint parts, in violation of various supplementation principles. This chapter offers a unified solution to the problems about transitivity and supplementation. One key ingredient in the solution is the view that parthood is a four-place relation expressed by ‘x at y is a part of z at w’. Another key ingredient is the view that the semantic contents of predicates and sentential connectives have ‘slots’ or ‘argument positions’ in them. (Both ingredients are independently motivated elsewhere.) Four-place analogues of the transitivity and supplementation principles are set out, and it is argued that these are not threatened by the examples from Frege and Bynoe. (shrink)

In this acclaimed work, first published in 1986, world-renowned scholar Arthur C. Danto explored the inextricably linked but often misunderstood relationship between art and philosophy. In light of the book's impact -- especially the essay "The End of Art," which dramatically announced that art ended in the 1960s -- this enhanced edition includes a foreword by Jonathan Gilmore that discusses how scholarship has changed in response to it. Complete with a new bibliography of work on and influenced by Danto's (...) ideas, _The Philosophical Disenfranchisement of Art_ continues to be of interest to anyone who thinks seriously about art, as well as to philosophers, aestheticians, and art historians.

According to a recent argument due to Wasserman, endurantism does not qualify as an explanatory theory of persistence inasmuch as it either provides a circular account of persistence facts or merely rejects the perdurantist’s explanation of such facts. This paper challenges Wasserman’s conclusions by pointing out that an endurantist answer to his complaint is available thanks to the locational notions of persistence provided in the work of Gilmore, Parsons, Balashov among others. It then gives details as to how such (...) notions can be used to answer Wasserman’s specific argument for the idea that endurantism is either unexplanatory or circular. After a brief introduction (Sect. 1 ) we provide the technical notions that we need to answer Wasserman’s complaint (Sect. 2 ) and offer a phrasing of endurantism which is immune to that complaint in terms of locative notions (Sect. 3 ). We then prove that two further conceptions of endurantism are entailed by that phrasing. Crucially, such conceptions are phrased in terms that Wasserman himself cannot, on pain of inconsistency, dismiss, as those are the very terms in which he conceives of endurantism in the first place—that is, whole presence and the rejection of temporal parts (Sect. 4 ).

I formulate a theory of persistence in the endurantist family and pose a problem for the conjunction of this theory with orthodox versions of special or general relativity. The problem centers around the question: Where are things?

Exploring the connections between autobiography and postmodernism, this book addresses self-representation in a variety of literatures - Native American, British, Chicana, immigrant, and lesbian, among others - in genres as diverse as poetry, naming, confession, photography, and the manifesto. The essays examine how different writers respond to the culturally specific pressures of genre, how these constraints are negotiated, and what self-representation reveals about the politics of identity.

Ethics networks have emerged over the last few decades as a mechanism for individuals and institutions over various regions, cities and states to converge on healthcare-related ethical issues. However, little is known about the development and nature of such networks. In an effort to fill the gap in the knowledge about such networks, a survey was conducted that evaluated the organizational structure, missions and functions, as well as the outcomes/products of ethics networks across the country. Eighteen established bioethics networks were (...) identified via consensus of three search processes and were approached for participation. The participants completed a survey developed for the purposes of this study and distributed via SurveyMonkey. Responses were obtained from 10 of the 18 identified and approached networks regarding topic areas of: Network Composition and Catchment Areas; Network Funding and Expenses; Personnel; Services; and Missions and Accomplishments. Bioethics networks are designed primarily to bring ethics education and support to professionals and hospitals. They do so over specifically defined areas—states, regions, or communities—and each is concerned about how to stay financially healthy. At the same time, the networks work off different organizational models, either as stand-alone organizations or as entities within existing organizational structures. (shrink)

Slot theory is the view that (i) there exist such entities as argument places, or ‘slots’, in universals, and that (ii) a universal u is n-adic if and only if there are n slots in u. I argue that those who take properties and relations to be abundant, fine-grained, non-set-theoretical entities face pressure to be slot theorists. I note that slots permit a natural account of the notion of adicy. I then consider a series of ‘slot-free’ accounts of that notion (...) and argue that each of them has significant drawbacks.

Since scholarly interest in corporate social responsibility (CSR) has primarily focused on the synergies between social and economic performance, our understanding of how (and the conditions under which) companies use CSR to produce policy outcomes that work against public welfare has remained comparatively underdeveloped. In particular, little is known about how corporate decision-makers privately reconcile the conflicts between public and private interests, even though this is likely to be relevant to understanding the limitations of CSR as a means of aligning (...) business activity with the broader public interest . This study addresses this issue using internal tobacco industry documents to explore British-American Tobacco’s (BAT) thinking on CSR and its effects on the company’s CSR Programme. The article presents a three-stage model of CSR development, based on Sykes and Matza’s theory of techniques of neutralization, which links together: how BAT managers made sense of the company’s declining political authority in the mid-1990s; how they subsequently justified the use of CSR as a tool of stakeholder management aimed at diffusing the political impact of public health advocates by breaking up political constituencies working towards evidence-based tobacco regulation; and how CSR works ideologically to shape stakeholders’ perceptions of the relative merits of competing approaches to tobacco control. Our analysis has three implications for research and practice. First, it underlines the importance of approaching corporate managers’ public comments on CSR critically and situating them in their economic, political and historical contexts. Second, it illustrates the importance of focusing on the political aims and effects of CSR. Third, by showing how CSR practices are used to stymie evidence-based government regulation, the article underlines the importance of highlighting and developing matrices to assess the negative social impacts of CSR.

Existing puzzles about coinciding objects can be divided into two types, corresponding to the manner in which they bear upon the endurantism v. perdurantism debate. Puzzles of the first type, which involve temporary spatial co-location, can be solved simply by abandoning endurantism in favor of perdurantism, whereas those of the second type, which involve career-long spatial co-location, remain equally puzzling on both views. I show that the possibility of backward time travel would give rise to a new type of puzzle. (...) The new puzzles confront perdurantists and can be solved just by shifting to endurantism. (shrink)

This article seeks to consider the policing of anti-fracking protests at Barton Moss, Salford, from November 2013 to April 2014. We argue that women at Barton Moss were considered by the police to be transgressing the socio-geographical boundaries that establish the dominant cultural and social order, and were thus responded to as disruptive and disorderly subjects. The article draws upon recent work on pacification, which views police power as having both destructive and productive dimensions, to consider the impact of police (...) violence on women involved in protest. We seek to explore the ways in which this violence impacts not only on those involved in protest but also those on the peripheries. The article suggests that the threat and use of sexual violence by police towards women aims to enforce compliance within the protest movement and to send a message, specifically to those on the fringes of the movement, that protest is illegitimate and inherently dangerous. As such, sexual violence forms part of the social production and construction of gender and is instrumental in the making and remaking of subjectivities. The case study suggests that police brutality towards women at Barton Moss, therefore, operated as a disciplinary function to regulate acceptable forms of protest and acceptable forms of femininity.

How is the debate between endurantism and perdurantism affected by the transition from pre-relativistic spacetimes to relativistic ones? After suggesting that the endurance vs. perdurance distinction may run together a pair of cross-cutting distinctions, I discuss two recent attempts to show that the transition in question does serious damage to endurantism.

Many philosophical accounts of the emotions conceive of them as susceptible to assessments of rationality, fittingness, or some other notion of aptness. Analogous assumptions apply in cases of emotions directed at what are taken to be only fictional or only imagined. My question is whether the criteria governing the aptness of emotions we have toward what we take to be real things apply invariantly to those emotions we have toward what we take to be only fictional or imagined. I argue (...) that what counts as a reason justifying an emotion can differ across real, fictional, and imagined domains. (shrink)

Public service organization's increasingly are considering diversification into new “for-profit” or “high-profit” enterprises. Such undertakings offer a number of potential benefits to both the organization and the public. They also have potential problems. This article examines some of the major types of benefits and problems in hopes that both public service managers and public policy makers will give a balanced consideration to these diversification efforts.

Endurantism, the view that material objects are wholly present at each moment of their careers, is under threat from supersubstantivalism, the view that material objects are identical to spacetime regions. I discuss three compromise positions. They are alike in that they all take material objects to be composed of spacetime points or regions without being identical to any such point or region. They differ in whether they permit multilocation and in whether they generate cases of mereologically coincident entities.
