The Telchines, magical craftsmen and wizards, are best known for their criticism of Callimachus’ poetry in the prologue to the Aetia. The other two appearances of the Telchines are also in programmatic passages in Callimachus’ extant works. In the Hymn to Delos (30–3), the narrator asks an aporetic question about the theme of his song. There, the Telchines are the makers of the trident used to form every island but Delos, highlighting her singular status as uniquely created without force (30–3). (...) In Aet. fr. 75, the Telchines appear in Xenomedes’ history of Ceos. There, Callimachus explicitly names one source for his material, but omits direct citation of equally important sources, namely Pindar and Bacchylides, while still alluding to their songs. This article examines verbal and thematic parallels among these three passages and argues that Callimachus uses the Telchines not only to link the passages but also to comment on his authorial process, his use of sources and his poetic programme.

The authors mark the twentieth anniversary of the classic study by Weitzman et al., which found considerable gender stereotyping in picture books for preschool children, by replicating and extending their study with an updated sample that includes books by Black illustrators. The authors find evidence that female characters and female relationships receive considerably more attention in recent books by both conventional illustrators and Black illustrators than they did in the late 1960s. They also find, consistent with the liberal feminist aims (...) of Weitzman et al., evidence that male and female characters are shown in a more egalitarian fashion than they were in the late 1960s in books by mainstream authors. Finally, they discover that, consistent with the aims of recent Black feminist theorists, Black illustrators are more apt than others to highlight women's involvement in an ethic of caring and an ethic of personal accountability.

Ownership is universal and ubiquitous in human societies, yet the psychology underpinning ownership intuitions is generally not described in a coherent and computationally tractable manner. Ownership intuitions are commonly assumed to derive from culturally transmitted social norms, or from a mentally represented implicit theory. While the social norms account is entirelyad hoc, the mental theory requires prior assumptions about possession and ownership that must be explained. Here I propose such an explanation, arguing that the intuitions result from the interaction of (...) two cognitive systems. One of these handles competitive interactions for the possession of resources observed in many species including humans. The other handles mutually beneficial cooperation between agents, as observed in communal sharing, collective action and trade. Together, these systems attend to specific cues in the environment, and produce definite intuitions such as “this is hers,” “that is not mine.” This computational model provides an explanation for ownership intuitions, not just in straightforward cases of property, but also in disputed ownership (squatters, indigenous rights), historical changes (abolition of slavery), as well as apparently marginal cases, such as the questions, whether people own their seats on the bus, or their places in a queue, and how people understand “cultural appropriation” and slavery. In contrast to some previous theories, the model is empirically testable and free ofad hocstipulations. (shrink)

Recent work in biology, cognitive psychology, and archaeology has renewed evolutionary perspectives on the role of natural selection in the emergence and recurrent forms of religious thought and behavior, i.e., mental representations of supernatural agents, as well as artifacts, ritual practices, moral systems, ethnic markers, and specific experiences associated with these representations. One perspective, inspired from behavioral ecology, attempts to measure the fitness effects of religious practices. Another set of models, representative of evolutionary psychology, explain religious thought and behavior as (...) the output of cognitive systems (e.g., animacy detection, social cognition, precautionary reasoning) that are not exclusive to the religious domain. In both perpectives, the question remains open, whether religious thought and behavior constitute an adaptation or a by-product of adaptive cognitive function. (shrink)

Promoting ethical decisions and behaviors is challenging for any organization. Yet managers are still required to make ethical decisions under conditions which deplete their self-control resources, such as high stress and long hours. This study examines the relationships among symbolic and internal moral identity, self-control, and ethical behavior, and investigates whether self-control acts as the mechanism through which moral identity leads to ethical behavior. Findings indicate that internal moral identity overrides symbolic moral identity in the relationship with self-control and that (...) self-control fully mediates the relationship between internal moral identity and ethical behavior. The implications for organizations is that while rules, procedures, and ethics training are useful, managers with a strong moral compass will be more likely to practice self-control leading to more ethical behaviors.

Ritualized behavior, intuitively recognizable by its stereotypy, rigidity, repetition, and apparent lack of rational motivation, is found in a variety of life conditions, customs, and everyday practices: in cultural rituals, whether religious or non-religious; in many children's complicated routines; in the pathology of obsessive-compulsive disorders (OCD); in normal adults around certain stages of the life-cycle, birthing in particular. Combining evidence from evolutionary anthropology, neuropsychology and neuroimaging, we propose an explanation of ritualized behavior in terms of an evolved Precaution System geared (...) to the detection of and reaction to inferred threats to fitness. This system, distinct from fear-systems geared to respond to manifest danger, includes a repertoire of clues for potential danger as well as a repertoire of species-typical precautions. In OCD pathology, this system does not supply a negative feedback to the appraisal of potential threats, resulting in doubts about the proper performance of precautions, and repetition of action. Also, anxiety levels focus the attention on low-level gestural units of behavior rather than on the goal-related higher-level units normally used in parsing the action-flow. Normally automatized actions are submitted to cognitive control. This “swamps” working memory, an effect of which is a temporary relief from intrusions but also their long-term strengthening. Normal activation of this Precaution System explains intrusions and ritual behaviors in normal adults. Gradual calibration of the system occurs through childhood rituals. Cultural mimicry of this system's normal input makes cultural rituals attention-grabbing and compelling. A number of empirical predictions follow from this synthetic model.

Written from the perspective of a liberal intellectual who has spent a lifetime as a writer, editor, and college professor, The Tyranny of Virtue is a precise and nuanced insider's look at shifts in American culture--most especially in the American academy--that so many people find alarming. Part memoir and part polemic, an anatomy of important and dangerous ideas, and a cri de coeur lamenting the erosion of standard liberal values, Boyers's collection of essays is devoted to such subjects as tolerance, (...) identity, privilege, appropriation, diversity, and ableism that have turned academic life into a minefield. Why, Robert Boyers asks, are a great many liberals, people who should know better, invested in the drawing up of enemies lists and driven by the conviction that on critical issues no dispute may be tolerated? In stories, anecdotes, and character profiles, a public intellectual and longtime professor takes on those in his own progressive cohort who labor in the grip of a poisonous and illiberal fundamentalism. The end result is a finely tuned work of cultural intervention from the front lines."--Inside front book jacket flap. (shrink)

A part of the scientific literature consists of intermediate results within a longer project. Scientists often publish a first result in the course of their work, while aware that they should soon achieve a more advanced result from this preliminary result. Should they follow the proverb “a bird in the hand is worth two in the bush”, and publish any intermediate result they get? This is the normative question addressed in this paper. My aim is to clarify, to refine, and (...) to assess informal arguments about the choice whether to publish intermediate results. To this end, I adopt a rational decision framework, supposing some utility or preferences, and I propose a formal model. The best publishing strategy turns out to depend on the research situation. In some simple circumstances, even selfish and short-minded scientists should publish their intermediate results, and should thus behave like their altruistic peers, i. e. like society would like them to behave. In other research situations, with inhomogeneous reward or difficulty profiles, the best strategy is opposite. These results suggest qualified philosophical morals. (shrink)

Research ethics review is a critical aspect of the research governance framework for human subjects research. This usually requires that research protocols be submitted to a research ethics committee for review and approval. This has led to very rapid developments in the domain of research ethics, as RECs proliferate all over the globe in rhyme with the explosion in human subjects research. The work of RECs has increasingly become elaborate, complex, and in many cases urgent, necessitating supporting rules and procedures (...) of operation. Guidelines for elaborating standard operating procedures for the functioning of RECs have also been proposed. The SOPs of well-placed and well-resourced RECs have tended to pay much attention to details, resulting, as a consequence, in generally long, elaborate, intricate and complex SOPs; a model that can hardly be replicated by other committees, equally under ethics review pressures, but working under much more constraining conditions in resource-destitute environments. In this paper, we looked at the content and length of SOPs from African RECs and compared them to the World Health Organization ’s guidelines as the gold standard. We also looked at the SOPs from the Ethics Review and Consultancy Committee of the Cameroon Bioethics Initiative that we elaborated in a simplified way in 2013, and compared them to the WHO’s guidelines and to the other SOPs. Sixteen SOPs from 14 African countries were collected from various sources. Their average length was of 30 pages. By comparison to the guidance of the WHO, only six of them were found acceptable with more than 70 % of the criteria from the gold standard that were fully described. Among those six, two of them were very long and detailed, while the four remaining SOPs ranged from 16 to 24 pages. The ERCC SOPs are seven pages long but maintain all that is of essence for the rigorous, efficient and timely review of protocols. We are convinced that, because of their brevity, simplicity, clarity and user-friendliness, the ERCC SOPs recommend themselves as a model template to, at least, committees similarly situated and/or circumstanced as the ERCC of the Cameroon Bioethics Initiative is. In fact, brevity, clarity, simplicity and user-friendliness are recognized values. Whatever is brief and clear is better than what is not and saves time. What is simple and user-friendly is better than what is not even though the two have the same aims because it saves both time and mental energy. And if this be true in general, it is even truer of the context and its peculiar constraints that we are addressing. (shrink)

In some applications to human beings, the precautionary principle seems to raise specific ethical concerns. For instance, it has been used by a business owner in a court of justice to justify his refusal to hire applicants with a certain geographical origin for safety reasons. Or in public management, the precautionary principle has been used to exclude men who have sexual relations with men from donating blood on the basis of a higher HIV prevalence in this group. Does not the (...) precautionary principle here amount to justifying a form of discrimination? To help analyze what is at stake from a decision-theoretic viewpoint and to consider the possibility of ethical catastrophes, we offer a lexical utility model of the precautionary principle, which generalizes a previous model by Bartha and DesRoches (Synthese 199:8701–8740, 2021), Steel and Bartha (Risk Anal https://doi.org/10.1111/risa.13892, 2022). Traditional expected utility theory also comes out as a special case of the model. Our proposal opens new perspectives for considering ethical dilemmas within a precautionary approach. It is intended to serve as a guiding tool for management teams in socially responsible companies, public institutions, and government agencies. (shrink)

We draw a distinction between the Aharonov–Bohm phase shift and the Aharonov–Bohm effect. Although the Aharonov–Bohm phase shift occurring when an electron beam passes around a magnetic solenoid is well-verified experimentally, it is not clear whether this phase shift occurs because of classical forces or because of a topological effect occurring in the absence of classical forces as claimed by Aharonov and Bohm. The mathematics of the Schroedinger equation itself does not reveal the physical basis for the effect. However, the (...) experimentally observed Aharonov–Bohm phase shift is of the same form as the shift observed due to electrostatic forces for which the consensus view accepts the role of the classical forces. The Aharonov–Bohm phase shift may well arise from classical electromagnetic forces which are simply more subtle in the magnetic case since they involve relativistic effects of the order v 2 /c 2 . Here we first review the experimentally observable differences between phenomena arising from classical forces and phenomena arising from the quantum topological effect suggested by Aharonov and Bohm. Second we point out that most discussions of the classical electromagnetic forces involved when a charged particle passes a solenoid are inaccurate because they omit the Faraday induction terms. The subtleties of the relativisitic v 2 /c 2 classical electromagnetic forces between a point charge and a solenoid have been explored by Coleman and Van Vleck in their analysis of the Shockley–James paradox; indeed, we point out that an analysis exactly parallel to that of Coleman and Van Vleck suggests that the Aharonov–Bohm phase shift is actually due to classical electromagnetic forces. Finally we note that electromagnetic velocity fields penetrate even excellent conductors in a form which is unfamiliar to many physicists. An ohmic conductor surrounding a solenoid does not screen out the magnetic field of the passing charge, but rather the time-integral of the magnetic field is an invariant; this time integral is precisely what is involved in the classical explanation of the Aharonov–Bohm phase shift. Thus the persistence of the Aharonov–Bohm phase shift when the solenoid is surrounded by a conductor does not exclude a classical force-based explanation for the phase shift. At present there is no experimental evidence for the Aharonov–Bohm effect. (shrink)

In reply to commentary on our target article, we supply further evidence and hypotheses in the description of ritualized behaviors in humans. Reactions to indirect fitness threats probably activate specialized precaution systems rather than a unified form of danger-avoidance or causal reasoning. Impairment of precaution systems may be present in pathologies other than obsessive-compulsive disorder (OCD), autism in particular. Ritualized behavior is attention-grabbing enough to be culturally transmitted whether or not it is associated with group identity, cohesion, or with any (...) other social aspect of collective ceremonies.

Epistemic accounts of scientific collaboration usually assume that, one way or another, two heads really are more than twice better than one. We show that this hypothesis is unduly strong. We present a deliberately crude model with unfavorable hypotheses. We show that, even then, when the priority rule is applied, large differences in successfulness can emerge from small differences in efficiency, with sometimes increasing marginal returns. We emphasize that success is sensitive to the structure of competing communities. Our results suggest (...) that purely epistemic explanations of the efficiency of collaborations are less plausible but have much more powerful socioepistemic versions. (shrink)

Although there is good experimental evidence for the Aharonov–Bohm phase shift occurring when a solenoid is placed between the beams forming a double-slit electron interference pattern, there has been very little analysis of the relevant classical electromagnetic forces. These forces between a point charge and a solenoid involve subtle relativistic effects of order v 2 /c 2 analogous to those discussed by Coleman and Van Vleck in their treatment of the Shockley–James paradox. In this article we show that a treatment (...) exactly analogous to that given by Coleman and Van Vleck predicts classical electromagnetic forces which provide the basis for the Aharonov–Bohm phase shift. The magnetic force on the solenoid due to the passing charge leads to a displacement of the solenoid center of energy which must be balanced by the displacement of the passing charge. This classical displacement of the passing charge is exactly what is required to account for the Aharonov–Bohm phase shift. Also, we discuss a magnetic moment model which appears frequently in the literature and note that although the model provides conservation of linear momentum, it does not satisfy the general requirements for relativistic theories. We give an example suggesting that the new equation of motion for a magnetic moment proposed by Aharonov, Pearle, and Vaidman based upon the hidden momentum of the magnetic moment is completely inappropriate. Finally, we emphasize that the Aharonov–Casher phase shift is also explained by classical electromagnetic forces exactly parallel to those explaining the Aharonov–Bohm phase shift. (shrink)

Human agents happen to judge that a conjunction of two terms is more probable than one of the terms, in contradiction with the rules of classical probabilities—this is the conjunction fallacy. One of the most discussed accounts of this fallacy is currently the quantum-like explanation, which relies on models exploiting the mathematics of quantum mechanics. The aim of this paper is to investigate the empirical adequacy of major quantum-like models which represent beliefs with quantum states. We first argue that they (...) can be tested in three different ways, in a question order effect configuration which is different from the traditional conjunction fallacy experiment. We then carry out our proposed experiment, with varied methodologies from experimental economics. The experimental results we get are at odds with the predictions of the quantum-like models. This strongly suggests that this quantum-like account of the conjunction fallacy fails. Future possible research paths are discussed. (shrink)

We describe a proof by a computer program of the unsolvability of the halting problem. The halting problem is posed in a constructive, formal language. The computational paradigm formalized is Pure LISP, not Turing machines. The machine was led to the proof by the authors, who suggested certain function definitions and stated certain intermediate lemmas. The machine checked that every suggested definition was admissible and the machine proved the main theorem and every lemma. We believe this is the first instance (...) of a machine checking that a given problem is not solvable by machine. (shrink)

At present classical physics contains two contradictory groups of derivations of the equilibrium spectrum of random classical electromagnetic radiation. One group of derivations finds Planck's spectrum based upon the use of classical electromagnetic zero-point radiation and fundamental ideas of thermodynamics. The other group of derivations finds the Rayleigh-Jeans spectrum from scattering equilibrium for non-linear mechanical systems in the limit of small charge coupling to radiation. Here we examine the scaling symmetries of classical thermal radiation. We find that, in general, classical (...) mechanical systems do not share the scaling symmetries of thermal radiation. In particular, this is true for the mechanical scattering systems used in the derivations of the Rayleigh-Jeans law. Indeed, relativistic hydrogenlike systems with Coulomb potentials of fixed charge are the only mechanical potential systems which do share the scaling symmetries of thermal radiation. We propose that only these last mechanical systems are allowed in a classical electromagnetic description of nature. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Ethical, Legal, and Social Implications Research Program at the National Human Genome Research InstituteEric M. Meslin (bio), Elizabeth J. Thomson (bio), and Joy T. Boyer (bio)Organizers of the Human Genome Project (HGP) understood from the beginning that the scientific activities of mapping and sequencing the human genome would raise ethical, legal, and social issues that would require careful attention by scientists, health care professionals, government officials, and (...) the public. The establishment of the ELSI (ethical, legal, and social implications) programs at the National Human Genome Research Institute (NHGRI) and the Department of Energy (DOE) was thought to be vital to the success of the HGP in the United States. It also provided a novel approach to the simultaneous study of ethical, legal, and social issues and basic scientific issues. Eric Juengst, the first director of the ELSI program, described its origins in a previous issue of the Kennedy Institute of Ethics Journal (Juengst 1991). Now in its seventh year, the ELSI program has accomplished much. This article summarizes the evolution and goals of the ELSI program at NHGRI, outlines the program’s current research priorities with examples of activities within each priority area, and provides a look to the future, including the initiation of a strategic planning process.Evolution and Goals of the ELSI Research ProgramThe HGP’s “genomic” goals are unique: to map and sequence the entire human genome—some 3 billion base pairs that make up approximately 80–100,000 genes—and the genomes of related model organisms by the year 2005. This goal was particularly ambitious since, when it was proposed, the technologies for mapping and sequencing had yet to be developed. When the HGP was first established, its organizers also elaborated a set of ELSI goals, which they saw as vital to the success of the genome project. The original ELSI goals were: (1) to anticipate and address the implications of the HGP for individuals and society and (2) to examine the ELSI consequences of mapping and sequencing the human genome in order to stimulate public discussion. To meet these goals, the NHGRI created its ELSI research program in 1990. Along with mapping, sequencing, [End Page 291] and mammalian genetics, ELSI was one of four original branches in the NHGRI Division of Extramural Research that funded research in those areas. Although the individual “branches” no longer exist, the mechanisms for funding research remain much the same. While the overall goals of the program have not changed, the specific ways of achieving the goals have continued to evolve. The importance of the ELSI program lies not in the collection of a full set of data that will be valuable in and of itself, but in the value of using and interpreting this new set of information.Early on, the NHGRI described a set of somewhat more specific goals: (1) to develop a program to help understand the ethical, legal, and social implications of the human genome project and (2) to identify and define the major issues of concern and develop policy options to address them. These more specific goals have been largely met. As the most recent biennial NHGRI Progress Report notes, “a robust ELSI research and education program has been established, many of the most urgent ELSI issues have been identified, and many policy options to address these issues have been proposed” (NCHGR 1995, p. 21). Between 1990 and 1996, ELSI provided more than $32.5 million in funding through 128 research and education grants in more than 30 states and in Canada (Table 1). The ELSI research budget is unique in that when originally created, it was specifically tied to the amount of money provided for the overall NHGRI budget. The NHGRI originally devoted 3 percent of its extramural budget to fund ELSI projects, but in FY 1991, it increased the ELSI budget to 5 percent, a figure that remains today. Table 2 lists the expenditures for each fiscal year since 1990 and the cumulative expenditures to date. The ELSI research budget at NHGRI this year will be about $7 million. When other sources of funding—e.g., co-funding arrangements with other institutes and agencies and the funding of ELSI... (shrink)

Identifying objects as members of ontological domains activates category-specific processes. There is evidence that these processes include particular ways of “tracking” substances and could do all the “tracking” necessary for concept acquisition. There may be no functional need or evolutionary scenario for a general tracking capacity of the kind described by Millikan.

Classical electromagnetic forces can account for the experimentally observed phase shifts seen in an electron interference pattern when a line of electric dipoles or a line of magnetic dipoles (a solenoid) is placed between the electron beams forming the interference pattern.

Aristotelian commenters have long noted an apparent contradiction between what Aristotle says in Posterior Analytics I.2 and Physics I.1 about how we obtain first principles of a science. At Posterior 71b35–72a6, Aristotle states that what is most universal (καθόλου) is better-known by nature and initially less-known to us, while the particular (καθ’ ἕκαστον) is initially better-known to us, but less-known by nature. At Physics 184a21-30, however, Aristotle states that we move from what is better-known to us, which is universal (καθόλου), (...) to what is better-known absolutely, which is particular (καθ’ ἕκαστον). This paper turns to two of Aristotle’s most notable medieval commentators—Albertus Magnus and Thomas Aquinas—to resolve this apparent contradiction. The key to Thomas and Albert’s solutions, we will argue, is a twofold distinction between a sense-perceptive and scientific universal, and the particulars as sensed individuals and as differentiating attributes. Our Synthetic treatment of these distinctions contributes to the ongoing scholarly effort to understand the Stagyrite’s complex theory of knowledge. (shrink)

La mécanique quantique est une théorie physique contemporaine réputée pour ses défis au sens commun et ses paradoxes. Depuis bientôt un siècle, plusieurs interprétations de la théorie ont été proposées par les physiciens et les philosophes, offrant des images quantiques du monde, ou des métaphysiques, radicalement différentes. L'existence d'un hasard fondamental, ou d'une multitude de mondes en-dehors du nôtre, dépend ainsi de l'interprétation adoptée. Cet article, en s'appuyant sur le livre Boyer-Kassem (2015), Qu'est-ce que la mécanique quantique ?, présente (...) trois principales interprétations quantiques, empiriquement équivalentes : l'interprétation dite orthodoxe, l'interprétation de Bohm, et l'interprétation des mondes multiples.

A large amount of research in cognitive psychology is focused on memory distortions, understood as deviations from various (largely implicit) standards. Many alleged distortions actually suggest a highly functional system that balances the cost of acquiring new information with the benefit of relevant, contextually appropriate decision-making. In this sense many memories may be examples of functionally adaptive misbelief.

L’ Apologie de John Rawls a paru aux Puf en 2018. Son objectif principal était le suivant : à supposer que la critique rawlsienne de la notion (ou de l’absence de la notion) de la personne dans la pensée utilitariste soit fondée, est-il légitime, étant donné la caractérisation par Rawls de son « principe de différence », de retourner sa propre critique anti-utilitariste contre lui, en arguant que lui non plus ne permet pas de fonder une notion concrète et complexe (...) de personne, ne laissant au lecteur qu’un pseudo-soi, purifié, hyper-abstrait, nouménal, détaché et désencastré de tout, une personne sans qualités, sans talents, aussi peu épaisse que la pseudo-personne utilitariste justement dénoncée par l’auteur de la TJ lui-même? Il s’agit donc de prendre au sérieux et de réfuter un argument de type Tu Quoque!, lequel retourne contre un argumentateur l’un de ses arguments critiques, en montrant que, malgré qu’il en eût, il tombe lui-même sous la critique qu’il a émise contre une tierce position. Cette stratégie argumentative, légitime, a été utilisée contre la TJ d’abord par Nozick, puis reprise et approfondie par le « communautarien » républicain anti-libéral Michael Sandel, et considérée comme valide par de nombreux auteurs. L’Apologie tente donc de répondre à cette accusation, et l’acquittement de John Rawls est proposé au lecteur. Ce ne sont pas les talents qui appartiennent au collectif, mais leur distribution différente peut être utilisée par la société comme fournissant une base adéquate pour des complémentarités et des coopérations bénéfiques à tous et en particulier aux plus démunis. L’argument de Nozick selon lequel le principe de différence n’est pas compatible avec tous les concepts parétiens est repris comme étant quant à lui valide. Une erreur terminologique sur les progressions parétiennes forte/faibles est ici corrigée. De plus, on tente d’y résoudre une perplexité sensible à la fin du chapitre V de l’Apologie. Il y a trois interprétations possibles du principe de différence, dont l’une est le simple maximin, et l’autre le leximin. On argue que ce principe n’est ni l’un ni l’autre, mais qu’il est formé par le couple lexicalement ordonné maximin et minimisation des inégalités, ce qui rend le principe de différence décisif, comme le leximin, sans courbes d’indifférence, comme en a le maximin. Malheureusement, cette caractérisation ne fonctionne qu’avec deux classes. Il faut sans doute admettre qu’il y a moins d’intuitions fortes concernant le sort des différentes classes moyennes pour définir la justice que concernant les actifs sur tout une vie, respectivement, des plus riches et des plus pauvres. Mais dans ce cas simple, représentable sur le plan, l’ambiguïté qui persistait dans l’Apologie est ici éliminée. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Aviation and the Aerial View:Le Corbusier's Spatial Transformations in the 1930s and 1940sM. Christine Boyer (bio)Part One: The Aerial ViewAviation and Equipment. A London publishing house, The Studio, Ltd, sent Le Corbusier a letter in January 1935, inquiring whether he would be interested in collaborating on a new series of books to be titled The New Vision. The promoters explained that each book in the series would be (...) devoted to a unique event in industrial design, with specific attention paid to the designers, their aims, and the potential these designs held for social and human development. They would begin the series with a volume on the airplane. Le Corbusier was asked to write an introductory essay, supply captions for the images they had already collected, and offer a few suggestions for additional illustrations.1Accepting the invitation, Le Corbusier in his reply, however, transformed the project: instead of the word "airplane" he preferred "aviation," by which he meant all the prodigious phenomena opening vast new horizons in space and influencing the future of "equipment" in the broadest sense of the word.2 Already in Precisions (1930) he had written, "I replace the word 'urbanism' by the term 'equipment.' I have already replaced the term 'furniture' by that of 'equipment.' Such stubbornness shows well that we are purely and simply claiming tools for work, for we do not want to die of hunger facing the embroidered flowerbeds of aesthetic urbanism" [143]. To his bag of equipment, Le Corbusier now adds "aviation," a tool of modern communication forging new modes of exchange and new links between nations.3The material subsequently sent by the publishing house to Le Corbusier also met with lukewarm reception: he favored more lively documentation such as the view from an airplane as it flew over cities—vast open terrain, the sea, and the forests. And he wanted more picturesque treatment of the lives of aviators, their psychological and social attitudes including analysis of the great aerial routes being drawn between Europe and America, Africa, or Asia. The publishing house was unable to fulfill Le Corbusier's [End Page 93] expectations, reminding him that their focus was limited to "the airplane" and that they expected to receive all his material by May.4What did Le Corbusier mean by "aviation" and the "epic of the air," a phrase he used in the preface of the subsequent book Aircraft (1935)? What new horizons did aviation open and how did this affect the perception of space and the process of reading the terrain as a two-dimensional map or a plan? And what did aviation have to do with "equipment"? Just the year before Le Corbusier had seen the Exposition de l'Aéronautique in Milan for which Mussolini offered the maxim: "Aviation is grand, small, or nothing at all, depending on whether public awareness of aviation is grand, small, or nothing at all."5 Le Corbusier, ever the great publicist, accepted the challenge to spread the meaning of "aviation" in the inclusive sense of the word entailing adventure and service, organization, and machinery.The rapid growth of aviation during the interwar period was mercurial, dramatically reshaping perception of the world and of space. There were daring flights of aviators challenging the breath of oceans and deserts, the heights of Everest, the length of Africa, the uncharted terrain of the North and South Poles. The airplane not only internationalized cartography; it was a tool for exploring and controlling the colonies. While aerial photography, which recorded in precise detail the realistic shape of landmasses, coastlines, seas, deserts, and mountains, perfected the process of mapmaking and enriched the documentary archive of the planet.Yet even more stunning, aviation continually shrunk the size of the globe after the initial KLM flight between Amsterdam and Jakarta took off in 1924. Then the time needed to navigate the 9000 miles was 55 days; within five years it had been reduced to a mere 12 days. A world map criss-crossed with national air routes came into view. In the 1930s civil airlines began to offer passenger and mail service between London and the Middle East, then on to India and... (shrink)

Why do we understand media the way we do? Sometimes we think about media simply as means of communication and instruments of human creativity. At other times we understand media as powerful technologies that influence human culture and that can even govern how we think and act. Dominic Boyer grapples with these complexities in Understanding Media, where he questions what our different strategies of engaging media actually tell us about media, their messages and powers." "Understanding Media explores, in a (...) serious yet entertaining way, our common habits of thinking about the presence and significance of media in our lives. Offering analysis of the philosophical and social foundations of contemporary media theory as well as everyday strategies of knowing media, it addresses the advantages and limitations of different ways of understanding media. Boyer also reflects on the practical issue of how we can know media better than we do."--Jacket. (shrink)

We describe an extension to our quantifier-free computational logic to provide the expressive power and convenience of bounded quantifiers and partial functions. By quantifier we mean a formal construct which introduces a bound or indicial variable whose scope is some subexpression of the quantifier expression. A familiar quantifier is the Σ operator which sums the values of an expression over some range of values on the bound variable. Our method is to represent expressions of the logic as objects in the (...) logic, to define an interpreter for such expressions as a function in the logic, and then define quantifiers as "mapping functions." The novelty of our approach lies in the formalization of the interpreter and its interaction with the underlying logic. Our method has several advantages over other formal systems that provide quantifiers and partial functions in a logical setting. The most important advantage is that proofs not involving quantification or partial recursive functions are not complicated by such notions as "capturing," "bottom," or "continuity." Naturally enough, our formalization of the partial functions is nonconstructive. The theorem prover for the logic has been modified to support these new features. We describe the modifications. The system has proved many theorems that could not previously be stated in our logic. Among them are. (shrink)

Background Pediatric critical care physician attitudes about withdrawal of ventricular assist devices (VAD) and extracorporeal membrane oxygenation (ECMO) in cases of medical futility are poorly defined. Our aim was to define current attitudes regarding the withdrawal of these devices. Methods IRB-approved, cross-sectional observational survey conducted among pediatric critical care attending physicians and fellow physicians in the United States between 2016 and 2017. Data was collected anonymously and statistically analyzed. Results A total of 158 physicians responded with 67% being attending physicians. (...) Compared to a VAD, a higher percentage had taken care of a patient on ECMO where the device was turned off because care was believed to be futile (99% vs. 84%), including currently (95% vs. 57%). Nearly all reported that it can be ethically permissible to withdraw support from a patient with a VAD and on ECMO (97% vs. 99%), but varied opinions existed as to who should ultimately make this decision if the patient/their family disagrees. More respondents agreed that a patient/their family should agree to withdrawal of VAD or ECMO support prior to initiation if futility is later determined (60% vs. 58%) and that protocols should be created for VAD and ECMO withdrawal (77% vs. 76%). Conclusion Most pediatric critical care physicians felt that it can be ethically permissible to withdraw VAD and ECMO support. Our study indicates that pediatric VAD and ECMO withdrawal protocols are desired, but further investigation is needed to determine how to best design protocols that would incorporate multiple stakeholders.

The analysis of this article is entirely within classical physics. Any attempt to describe nature within classical physics requires the presence of Lorentz-invariant classical electromagnetic zero-point radiation so as to account for the Casimir forces between parallel conducting plates at low temperatures. Furthermore, conformal symmetry carries solutions of Maxwell’s equations into solutions. In an inertial frame, conformal symmetry leaves zero-point radiation invariant and does not connect it to non-zero-temperature; time-dilating conformal transformations carry the Lorentz-invariant zero-point radiation spectrum into zero-point radiation (...) and carry the thermal radiation spectrum at non-zero temperature into thermal radiation at a different non-zero temperature. However, in a non-inertial frame, a time-dilating conformal transformation carries classical zero-point radiation into thermal radiation at a finite non-zero-temperature. By taking the no-acceleration limit, one can obtain the Planck radiation spectrum for blackbody radiation in an inertial frame from the thermal radiation spectrum in an accelerating frame. Here this connection between zero-point radiation and thermal radiation is illustrated for a scalar radiation field in a Rindler frame undergoing relativistic uniform proper acceleration through flat spacetime in two spacetime dimensions. The analysis indicates that the Planck radiation spectrum for thermal radiation follows from zero-point radiation and the structure of relativistic spacetime in classical physics. (shrink)
