The Drake Relays are one of the iconic events of track and field in the United States. World and Olympic champions test their speed and stamina on the famed Blue Oval in Des Moines, Iowa, every April, and by spring 2013 they had set fourteen world records and fifty-one American records. But unlike most other top meets, this one also features college athletes from all over the country and high school athletes from across Iowa, giving them the experience of (...) a lifetime—competing on the same track with the elite in their sport. This mix brings many enthusiastic spectators to the stadium and makes for an unusually close bond between fans and athletes—it’s as if everyone’s family is there cheering. Pulitzer Prize–winning photographer David Peterson has been covering the Drake Relays for nearly forty years, but his love affair with the meet started earlier, when he ran on three winning relay teams there for Kansas State University. Now, drawing upon an unmatched personal archive, he offers the pictures of a lifetime spent on the Blue Oval. He captures on camera athletes of all levels in triumph and defeat, in mid-stride or leap, embracing their fans, their moms and dads, and their kids. In addition to the stars of the past, such as Carl Lewis, Suzy Favor Hamilton, and Herschel Walker, and those of the ’00s, like Lolo Jones and Jeremy Wariner, we see teenagers who may be the stars of the future, as well as the many athletes who will never be famous but nonetheless show themselves—and their sport—at their best. A beautiful celebration of the Drake Relays and the diverse sports that make up “track and field,” this book will evoke memories and inspire runners, throwers, and jumpers everywhere. (shrink)

This paper forms part of a wider campaign: to deny pointillisme, the doctrine that a physical theory's fundamental quantities are defined at points of space or of spacetime, and represent intrinsic properties of such points or point-sized objects located there; so that properties of spatial or spatiotemporal regions and their material contents are determined by the point-by-point facts. More specifically, this paper argues against pointillisme about the concept of velocity in classical mechanics; especially against proposals by Tooley, Robinson and Lewis. (...) A companion paper argues against pointillisme about -geometry, as proposed by Bricker. To avoid technicalities, I conduct the argument almost entirely in the context of "Newtonian" ideas about space and time, and the classical mechanics of point-particles, i.e. extensionless particles moving in a void. But both the debate and my arguments carry over to relativistic physics.

We survey some philosophical aspects of the search for a quantum theory of gravity, emphasising how quantum gravity throws into doubt the treatment of spacetime common to the two `ingredient theories' (quantum theory and general relativity), as a 4-dimensional manifold equipped with a Lorentzian metric. After an introduction (Section 1), we briefly review the conceptual problems of the ingredient theories (Section 2) and introduce the enterprise of quantum gravity (Section 3). We then describe how three main research programmes in quantum (...) gravity treat four topics of particular importance: the scope of standard quantum theory; the nature of spacetime; spacetime diffeomorphisms, and the so-called `problem of time' (Section 4). These programmes are the old particle-physics approach, superstring theory, and canonical quantum gravity. By and large, these programmes accept most of the ingredient theories' treatment of spacetime, albeit with a metric with some type of quantum nature; but they also suggest that the treatment has fundamental limitations. This prompts the idea of going further: either by quantizing structures other than the metric, such as the topology; or by regarding such structures as phenomenological. We discuss this in Section 5.

“Now, in calm weather, to swim in the open ocean is as easy to the practised swimmer as to ride in a spring-carriage ashore. But the awful lonesomeness is intolerable. The intense concentration of self in the middle of such a heartless immensity, my God! who can tell it? Mark, how when sailors in a dead calm bathe in the open sea—mark how closely they hug their ship and only coast along her sides.” (Herman Melville, Moby Dick, Chapter 94).

Theories of children's developing understanding of mind tend to emphasize either individualistic processes of theory formation, maturation, or introspection, or the process of enculturation. However, such theories must be able to account for the accumulating evidence of the role of social interaction in the development of social understanding. We propose an alternative account, according to which the development of children's social understanding occurs within triadic interaction involving the child's experience of the world as well as communicative interaction with others about (...) their experience and beliefs (Chapman 1991; 1999). It is through such triadic interaction that children gradually construct knowledge of the world as well as knowledge of other people. We contend that the extent and nature of the social interaction children experience will influence the development of children's social understanding. Increased opportunity to engage in cooperative social interaction and exposure to talk about mental states should facilitate the development of social understanding. We review evidence suggesting that children's understanding of mind develops gradually in the context of social interaction. Therefore, we need a theory of development in this area that accords a fundamental role to social interaction, yet does not assume that children simply adopt socially available knowledge but rather that children construct an understanding of mind within social interaction. Key Words: language; Piaget; social interaction; theories of mind; Vygotsky; Wittgenstein. (shrink)

Did Plato intend the laws of the Laws to change? While most scholars agree that there is to be legal change in Magnesia, I contend that this issue has been clouded by confusing three distinct questions: (1) whether there are legal mechanisms for changing the law in Magnesia, (2) what the attitudes of Magnesian citizens towards innovation and legal change are, and (3) whether Plato thinks the law is always the ultimate political authority. Once we separate these issues and look (...) at the relevant texts more closely, we see that the Athenian Visitor is primarily concerned with supplementing the original lawgiver’s laws and that any innovation that occurs should be consistent with this lawcode. This does not settle the question about whether it is always right to act in accordance with the existing laws, though it does provide a valuable framework for understanding a central aspect of Platonic political philosophy. Thus, although Plato’s ideal places knowledge above the law, in practice the laws of Magnesia will be fixed and authoritative for those people living under them. (shrink)

Properly understood, the instrumental rule says to take means that actually suffice for my end, not, as is nearly universally assumed, to intend means that I believe are necessary for my end. This alternative explains everything the standard interpretation can—and more, including grounding certain correctness conditions for exercises of our will unexplained by the standard interpretation.

This paper forms part of a wider campaign: to deny pointillisme. That is the doctrine that a physical theory's fundamental quantities are defined at points of space or of spacetime, and represent intrinsic properties of such points or point-sized objects located there; so that properties of spatial or spatiotemporal regions and their material contents are determined by the point-by-point facts. More specifically, this paper argues against pointillisme about the structure of space and-or spacetime itself, especially a paper by Bricker (1993). (...) A companion paper argues against pointillisme in mechanics, especially about velocity; it focusses on Tooley, Robinson and Lewis. To avoid technicalities, I conduct the argument almost entirely in the context of ``Newtonian'' ideas about space and time. But both the debate and my arguments carry over to relativistic, and even quantum, physics. (shrink)

Do property entitlements define the moral environment in which rights to well-being are defined, or do rights to well-being define the moral environment in which property entitlements are defined? Robert Nozick argued for the former alternative and he denied that any serious attempt had been made to state the latter alternative (what he called “the ‘reverse’ theory”). I actually think John Locke's approach to property can be seen as an instance of the “reverse” theory. And Nozick's can too, inasmuch as (...) it shares a number of features with the Lockean approach. But my paper is not intended as a criticism of Nozick; on the contrary, it acknowledges the integrity and the importance of his insistence that welfare, property, and justice be integrated into a single theory with clearly established priorities.

In The Metaphysics of Truth, Doug Edwards offers a sustained case against deflationism about truth and in favour of his preferred pluralist theory of truth. Here, I take up three of the main components of that case. The first is Edwards' account of the distinctive metaphysical commitments of deflationism. His views about this issue have changed over the past few years, and I detail these changes as well as a concern for the views that he develops in the book. Second, (...) I take up the argument that Edwards offers for thinking that deflationism is, in a certain sense, internally unstable. I explain why this argument is inconclusive, outlining three responses to it on behalf of the deflationist. Third, I consider Edwards' novel argument for truth pluralism, which acts as an indirect argument against deflationism. After sorting out some interpretive nuances related to the use of definite descriptions in this argument, I show how the deflationist can resist it. Having responded to Edwards' critique of deflationism, I close by briefly explaining why I take the methodology of deflationism to be especially promising, insofar as it underscores the significance of empirically-informed inquiry about truth.

The evidence for a positive, direct link between the representation of women on boards of directors and financial performance is tenuous. Given the importance of the gender diversity–financial performance debate, researchers are left to examine how, if at all, the two are linked. The present study takes the position that the link is indirect. Specifically, following stakeholder theory, an argument is made that women on boards’ attunement to stakeholder interests leads them to influence firms’ prosocial actions, which results in higher (...) levels of corporate social responsibility. In turn, following the extant literature, CSR is expected to be positively linked to financial performance. Relying on a sample of Australia’s largest publicly traded firms, the results demonstrate that women on boards are linked to CSR and that CSR is linked to financial performance. However, in the mediation test, CSR appears to fully mediate the link between women on boards and financial performance. The results are discussed along with limitations and future research directions. (shrink)

Although the pedagogy literature indicates significant relationships between cheating intentions and both personal and situational factors, no published research has examined the joint effect of personal moral philosophy and perceived moral intensity components on students’ cheating intentions. Hence, a structural equation model that relates magnitude of consequences, relativism, and idealism to willingness to cheat, is developed and tested. Using data from undergraduate business students, the empirical results provide insight into these relationships and evidence of mediation for magnitude of consequences on (...) idealism and students’ cheating intentions. Implications for educators are offered. (shrink)

We show that the theory ATR0 is equivalent to a second-order generalization of the theory $\widehat{ID}_{<\omega}$. As a result, ATR0 is conservative over $\widehat{ID}_{<\omega}$ for arithmetic sentences, though proofs in ATR0 can be much shorter than their $\widehat{ID}_{<\omega}$ counterparts.

We present a simple propositional proof system which consists of a single axiom schema and a single rule, and use this system to construct a sequence of combinatorial tautologies that, when added to any Frege system, p-simulates extended-Frege systems.

In 1985, van den Dries showed that the theory of the reals with a predicate for the integer powers of two admits quantifier elimination in an expanded language, and is hence decidable. He gave a model-theoretical argument, which provides no apparent bounds on the complexity of a decision procedure. We provide a syntactical argument that yields a procedure that is primitive recursive, although not elementary.

The rotating discs argument against perdurantism has been mostly discussed by metaphysicians, though the argument of course appeals to ideas from classical mechanics, especially about rotation. In contrast, I assess the RDA from the perspective of the philosophy of physics. I argue for three main conclusions. The first conclusion is that the RDA can be formulated more strongly than is usually recognized: it is not necessary to ‘imagine away’ the dynamical effects of rotation. The second is that in general relativity, (...) the RDA fails because of frame-dragging. The third conclusion is that even setting aside general relativity, the strong formulation of the RDA can after all be defeated, namely, by the perdurantist taking objects in classical mechanics to have only temporally extended temporal parts, which immediately blocks the RDA. Admittedly, this version of perdurantism defines persistence in a weaker sense of ‘definition’ than pointilliste versions that aim to define persistence assuming only instantaneous temporal parts. But I argue that temporally extended temporal parts can do the jobs within the endurantism– perdurantism debate that the perdurantist wants temporal parts to do and are supported by both classical and quantum mechanics. Introduction The story so far 2.1 The RDA 2.2 Intrinsic properties and the idea of velocity 2.2.1 The intrinsic–extrinsic distinction 2.2.2 Velocity to the rescue? 2.3 ‘Naturalism’ 2.4 The accompaniments of rotation 2.5 Two kinds of reply: against the consensus Describing rotation 3.1 Rotation is kinematic 3.2 Beware of rigidity 3.3 An improved RDA: allowing the actual accompaniments 3.4 The RDA fails in general relativity Perdurantism without tears: the classical case 4.1 Rejecting instantaneous temporal parts 4.2 Replying to the RDA 4.2.1 ‘Kinematics’ 4.2.2 ‘Dynamics’ 4.2.3 An ‘anti-pointilliste’ objection and reply 4.3 Intrinsic properties of non-instantaneous temporal parts 4.3.1 Can the perdurantist appeal to them? 4.3.2 Temporal intrinsicality at an instant is rare 4.3.3 A better reason for temporal intrinsicality 4.4 Non-instantaneous parts can do the jobs 4.4.1 Humean supervenience revisited 4.4.2 The problem of change 4.4.3 Puzzles of coincidence 4.5 Instantaneous velocity is hardly extrinsic Support from decoherence in quantum theory 5.1 Classical and quantum: relativizing the intrinsic–extrinsic distinction 5.1.1 Unitarity: momentum as temporally intrinsic 5.2 Position and existence as nomically extrinsic.

Hypnosis is considered a unique tool capable of modulating cognitive processes. The extent to which hypnotic suggestions intervenes is still under debate. This study was designed to provide a new insight into this issue, by focusing on an unintentional emotional process: attentional bias. In Experiment 1, highly suggestible participants performed three sessions of an emotional Stroop task where hypnotic suggestions aiming to increase and decrease emotional reactivity towards emotional stimuli were administered within an intra-individual design. Compared to a baseline condition (...) (without hypnotic suggestion), a significant increase in attentional bias was found when a hypnotic suggestion to increase emotional reactivity was administered. In contrast, the bias was eliminated when a suggestion to decrease emotional reactivity was administered. Experiment 2 investigated the effect of session repetition on attentional bias across three successive experimental sessions without hypnosis, and showed that the emotional Stroop effect did not vary across sessions. Hence, session repetition could not account for part of the modulation of attentional bias in Experiment 1. Taken together, the results suggest that specific hypnotic suggestions can influence elicitation of unintentional emotional processing. The implications are discussed regarding the locus of intervention of hypnotic suggestion in cognitive and emotional processes. (shrink)

Is there anything in the mind that was not first in the senses? According to the received view, the French empiricist Étienne Bonnot de Condillac’s answer to this was a firm “No”. Unlike Locke, who accepted the existence of innate faculties, Condillac rejected the existence of all innate structure and instinctive behaviours. Everything, therefore, is learned. In this article, I argue that from at least the writing of his 1754 Traité des sensations, this reading fails to capture the true nature (...) of his philosophy of mind. I present a genetic reading of Condillac’s philosophy that shows that from the 1750s until his death in 1780, he developed, by engaging closely with the life sciences of his day, an increasingly sophisticated understanding of the mind and perception. This understanding depends on the acceptance of the activity of the mind, innate structure, and a moderate defence of instincts—all characteristics of the mind that he is most commonly read as rejecting. Reading Condillac in this genetic way demonstrates that his philosophy of mind is much more original and powerful than has previously been recognised. (shrink)

Susan Hurley's shared circuits model (SCM) rightly begins in action and progresses through a series of layers; but it fails to reach action understanding because it relies on mirroring as a driving force, draws on heavily criticized theories, and neglects the need for shared experience in our grasp of social understanding.

The building of the transcontinental railroad in the US Central West in the late 1860s greatly improved access to this region and led to the expansion of scientific field work. The relationships between science and the railroad spanned a diverse spectrum, ranging from its practical advantages to more complex interactions such as the transformation of nature along railway corridors and the reciprocal exchange of favours between scientists and railway companies. The dominance of science along the railroad in the second half (...) of the nineteenth century continued into the early twentieth century, with a gradual shift to automobile travel beginning in the 1910s. By stimulating and shaping field research both on and off the railway corridor, the laying of iron tracks across the continent helped guide US science, just as it influenced so many other aspects of US life.

By the middle of the nineteenth century, it had become clear to mathematicians that the study of finite field extensions of the rational numbers is indispensable to number theory, even if one’s ultimate goal is to understand properties of diophantine expressions and equations in the ordinary integers. It can happen, however, that the “integers” in such extensions fail to satisfy unique factorization, a property that is central to reasoning about the ordinary integers. In 1844, Ernst Kummer observed that unique factorization (...) fails for the cyclotomic integers with exponent 23, i.e. the ring Z[ζ] of integers of the field Q(ζ), where ζ is a primitive twenty-third root of unity. In 1847, he published his theory of “ideal divisors” for cyclotomic integers with prime exponent. This was to remedy the situation by introducing, for each such ring of integers, an enlarged domain of divisors, and showing that each integer factors uniquely as a product of these. He did not actually construct these integers, but, rather, showed how one could characterize their behavior qua divisibility in terms of ordinary operations on the associated ring of integers.

As Newton realized, his absolute space was a ‘conspiracy of nature’ in the sense that his laws dictated that nobody could discover who, among all possible observers (in various states of motion relative to one another), was at rest in absolute space. So absolute space was an unverifiable element of his theory.

Despite a significant amount of literature debating the efficiency of high-risk pools in health insurance, dramatically less has been written about their normative implications. The present article takes the route less traveled by setting aside the question of efficiency to argue that the use of high-risk pools creates some serious normative concerns. The article explores these concerns by dividing them on two fronts. First, as regards the social-recognitional status of those who are forced into the high-risk pool. Second, as regards (...) a general concern of distributive justice, namely fairness in access to resources. The author argues that regardless of the veracity of arguments which laud the efficiency of high-risk pools, their use in health insurance is unjust because of the herein explained implications for social recognition and distributive justice.

By focusing on the caloric composition of hunted prey species, optimal foraging research has shown that hunters usually make economically rational prey choice decisions. However, research by meat scientists suggests that the gustatory appeal of wildlife meats may vary dramatically. In this study, behavioral research indicates that Mayangna and Miskito hunters in Nicaragua inconsistently pursue multiple prey types in the optimal diet set. We use cognitive methods, including unconstrained pile sorts and cultural consensus analysis, to investigate the hypothesis that these (...) partial preferences are influenced by considerations of meat flavor. Native informants exhibit high agreement on the relative appeal of different meats. Given the absence of other noteworthy differences between spider monkeys (Ateles geoffroyi) and howler monkeys (Alouatta palliata), the unappealing flavor of howler monkeys seems to be a factor in the partial preference for this species.

On New year's Eve 1992 a man suffering from schizophrenia climbed into a lions' cage at the London Zoo and was badly mauled. This event provoked a full-scale moral panic among the media and government, the tragedy seeming to violate many of the comfortable myths about progress in psychiatry, echoing the impact of the civil war in former Yugoslavia which had shattered the hope of an era of unbroken European peace following the end of the cold war. Whatever we may (...) wish in reality the lion does not lie down with the lamb.

Background Disaster scenarios challenge both novice and experienced nurses to navigate complex ethical dilemmas in resource-limited environments. Traditional nursing education often leaves new nurses unprepared for the ethical demands of disaster nursing. Utilitarianism must often guide triage ethics and decision-making. There is a critical need to equip nursing students with these ethical competencies. Research question/Aim This study explores nursing students’ lived experiences using introductory triage ethics in mass casualty incident simulation (MCIS). Research design A qualitative, interpretive phenomenological approach was employed, (...) analyzing reflective journal responses from senior nursing students following MCIS participation. Participants and research context Participants were senior-year nursing students from a private university in the U.S., engaging in MCIS as part of their curriculum, which simulated resource-limited disaster scenarios requiring real-time ethical decisions. Ethical considerations The study received Institutional Review Board (IRB) approval, and participants provided informed consent. Data were anonymized and did not affect academic evaluation. Findings Two major themes emerged: 1. Living in Ethical Dilemmas (subthemes: We Could Have Saved Them If…, Looking Past Obvious Suffering, How Can We Be Prepared?, We Can’t Abandon Them). 2. Development of Ethical Competency (subthemes: Knowing You’ve Done Enough, Finding New Perspectives, There Is No Right Answer). Students grew in moral reasoning and emotional resilience, transitioning from patient-centered care to utilitarian decision-making. Conclusions Participation in the mass casualty incident simulation allowed nursing students to confront and navigate complex ethical challenges in real time, fostering significant growth in moral reasoning and emotional resilience. Through immersion in simulated ethical dilemmas, students grappled with the tension between patient-centered care and the realities of utilitarian decision-making. This experience catalyzed a deeper understanding of ethical ambiguity and the development of moral clarity, equipping them with foundational skills for ethically navigating crises. Nursing curricula should recognize and incorporate opportunities that facilitate this ethical growth through experiential learning. (shrink)
