Efforts from diverse disciplines, including evolutionary studies and biomechanical experiments, have yielded new insights into the genetic, signaling, and mechanical control of tooth formation and functions. Evidence from fossils and non‐model organisms has revealed that a common set of genes underlie tooth‐forming potential of epithelia, and changes in signaling environments subsequently result in specialized dentitions, maintenance of dental stem cells, and other phenotypic adaptations. In addition to chemical signaling, tissue forces generated through epithelial contraction, differential growth, and skeletal constraints act (...) in parallel to shape the tooth throughout development. Here recent advances in understanding dental development from these studies are reviewed and important gaps that can be filled through continued application of evolutionary and biomechanical approaches are discussed.

Uchiyama et al. reveal how group-structured cultural variation influences measurements of trait heritability. We argue that understanding culture's influence on phenotypic heritability can clarify the impact of culture on genetic inheritance, which has implications for long-term gene–culture coevolution. Their analysis may provide guidance for testing our hypothesis that cultural adaptation is superseding genetic adaptation in the long term.

We link cleansing effects to contemporary cognitive theories via an account of event representation that provides an explicit, neurally plausible mechanism for encoding objects and their associations across time. It explains separation as resulting from weakening associations between the self in the present and the self in the past.

Television medical dramas frequently depict the practice of medicine and bioethical issues in a strikingly realistic but sometimes inaccurate fashion. Because these shows depict medicine so vividly and are so relevant to the career interests of medical and nursing students, they may affect these students' beliefs, attitudes, and perceptions regarding the practice of medicine and bioethical issues. We conducted a web-based survey of medical and nursing students to determine the medical drama viewing habits and impressions of bioethical issues depicted in (...) them. More than 80% of medical and nursing students watch television medical dramas. Students with more clinical experience tended to have impressions that were more negative than those of students without clinical experience. Furthermore, viewing of television medical dramas is a social event and many students discuss the bioethical issues they observe with friends and family. Television medical dramas may stimulate students to think about and discuss bioethical issues. (shrink)

Aim: Patients with advanced cancer need information about end-of-life treatment options in order to make informed decisions. Clinicians vary in the frequency with which they initiate these discussions.Patients and methods: As part of a long-term longitudinal study, patients with an expected 2-year survival of less than 50% who had advanced gastrointestinal or lung cancer or amyotrophic lateral sclerosis were interviewed. Each patient’s medical record was reviewed at enrollment and at 3 months for evidence of the discussion of patient wishes concerning (...) ventilator support, artificial nutrition and hydration , resuscitation and hospice care. A Kaplan–Meier analysis was also performed and 2-year survival calculated.Results: 60 cancer and 32 ALS patients were enrolled. ALS patients were more likely than cancer patients to have evidence of discussion about their wishes for ventilator support , ANH , DNR and hospice care . At 6 months, 91% of ALS patients were alive compared with 62% of cancer patients; at 2 years, 63% of ALS patients were alive compared with 23% of cancer patients .Conclusions: Cancer patients were less likely than ALS patients to have had documented advanced care planning discussions despite worse survival. This may reflect perceptions that ALS has a more predictable course, that advanced cancer has a greater number of treatment options, or differing views about hope. Nevertheless, cancer patients may be less adequately prepared for end-of-life decision-making. (shrink)

High-spin states have been studied in Pr-135(59), populated through the Cd-116(Na-23,4n) reaction at 115 MeV, using the Gammasphere gamma-ray spectrometer. The negative-parity yrast band has been significantly extended to spin similar to 45 (h) over bar and excitation energy 21.5 MeV, showing evidence for several rotational alignments. The positive-parity yrast band of Ce-135(58), populated through the p4n channel of this reaction, was also populated to spin similar to 38 (h) over bar and excitation energy 18 MeV. Cranking calculations indicate that (...) these nuclei are soft with respect to the triaxiality parameter gamma and that several competing nuclear shapes occur at high spin. (shrink)

When the COVID-19 surge hit New York City hospitals, the Division of Medical Ethics at Weill Cornell Medical College, and our affiliated ethics consultation services, faced waves of ethical issues sweeping forward with intensity and urgency. In this article, we describe our experience over an eight-week period (16 March through 10 May 2020), and describe three types of services: clinical ethics consultation (CEC); service practice communications/interventions (SPCI); and organizational ethics advisement (OEA). We tell this narrative through the prism of time, (...) describing the evolution of ethical issues and trends as the pandemic unfolded. We delineate three phases: anticipation and preparation, crisis management, and reflection and adjustment. The first phase focused predominantly on ways to address impending resource shortages and to plan for remote ethics consultation, and CECs focused on code status discussions with surrogates. The second phase was characterized by the dramatic convergence of a rapid increase in the number of critically ill patients, a growing scarcity of resources, and the reassignment/ redeployment of staff outside their specialty areas. The third phase was characterized by the recognition that while the worst of the crisis was waning, its medium- and long-term consequences continued to pose immense challenges. We note that there were times during the crisis that serving in the role of clinical ethics consultant created a sense of dis-ease as novel as the coronavirus itself. In retrospect we learned that our activities far exceeded the familiar terrain of clinical ethics consultation and extended into other spheres of organizational life in novel ways that were unanticipated before this pandemic. To that end, we defined and categorized a middle level of ethics consultation, which we have termed service practice communication intervention (SPCI). This is an underappreciated dimension of the work that ethics consult services are capable of in times of crisis. We believe that the pandemic has revealed the many enduring ways that ethics consultation services can more robustly contribute to the ethical life of their institutions moving forward. (shrink)

Much has been written about the ethics of eating meat. Far less has been said about the ethics of serving meat. In this paper I argue that we often shouldn’t serve meat, even if it is morally permissible for individuals to purchase and eat meat. Historically, the ethical conversation surrounding meat has been limited to individual diets, meat producers, and government actors. I argue that if we stop the conversation there, then the urgent moral problems associated with industrial animal agriculture (...) will go unsolved. Instead, we must also consider the important but overlooked role that midsized institutions play in addressing major collective problems. I focus mostly on the harms that industrial animal agriculture inflicts on humans, animals, and the environment, but the discussion bears on other global issues like climate change. Institutional choices are an underexplored avenue for driving social change—their power and influence outstrip individual actions, and they can shape behavior in modest ways that promote social goods. Here I highlight the paradigmatic case of catered events and suggest three ways that institutional actors can reduce meat consumption and shape cultural attitudes surrounding meat: large impact decisions, subtly shaping incentives, and consolidating burdens.

Jewish Agrarian Movements (JAM hereafter) in North America express the many different shapes and iterations of Jewish farming on the continent, grounded in historical perspectives that influence current practices and activities. From within this diversity, common threads emerge with much to contribute to agrarian social movements and scholarship. Jewish values of returning (_t_’_shuvah_), releasing (_shmitah_), and repairing (_tikkun_), along with theories of _doikayt_ (an anti-zionist movement around “hereness”) and radical diasporism, animate JAM’s critical engagement with agri-food systems. As researchers who (...) have both studied and participated in Jewish agrarianism in a variety of U.S. and Canadian contexts, we solidify a series of themes and tensions that emerge from JAM: diaspora and indigeneity, modernity and tradition, Jewish agroecological knowledge production, and lived religion. We argue that, while JAM has not yet been examined thoroughly within critical food scholarship, it has the potential to contribute to broader debates and frameworks within sub-fields such as radical food geographies, critical agrarianism, and decoloniality. Without consideration of JAM as a part the study of food and agriculture, there are risks of marginalization of farmers, activists and researchers of Jewish identity. (shrink)

Recently advocates of the propensity interpretation of fitness have turned critics. To accommodate examples from the population genetics literature they conclude that fitness is better defined broadly as a family of propensities rather than the propensity to contribute descendants to some future generation. We argue that the propensity theorists have misunderstood the deeper ramifications of the examples they cite. These examples demonstrate why there are factors outside of propensities that determine fitness. We go on to argue for the more general (...) thesis that no account of fitness can satisfy the desiderata that have motivated the propensity account. (shrink)

We discuss explanation of an earlier event by a later event, and argue that prima facie cases of backwards event explanation are ubiquitous. Some examples: (1) I am tidying my flat because my brother is coming to visit tomorrow. (2) The scarlet pimpernels are closing because it is about to rain. (3) The volcano is smoking because it is going to erupt soon. We then look at various ways people might attempt to explain away these prima facie cases by arguing (...) that in each case the 'real' explanation is something else. We argue that none of the explaining-away strategies are successful, and so any plausible account of explanation should either make room for backwards explanation, or have a good story to tell about why it doesn't have to.

Many of us have encountered a version of what Zachary Horton calls the "cosmic zoom"--a visual journey through the many scales of the universe, from the microscopic to the cosmic. Most of our daily perception operates at a level of scale somewhere between that of quarks and galaxies, and it is this comfort with the immediately visible everyday world that the cosmic zoom unsettles. In Mediating Scale, Horton uses the history of the cosmic zoom to explore how that scale (...) itself has been constructed over the past seventy years. How has cosmic zoom media influenced scientific and popular understanding of the unseen world and how it may be known, accessed, and exploited? Horton insists that scale is the key to understanding and addressing major contemporary issues including climate change and big data, but people working on issues of scale in various disciplines often talk past each other. Horton starts by sketching four common ways of thinking about scale derived from cartography, physics, engineering/biology, and mathematics. He then shows how these concepts operate in various disciplines, explains why they don't fit together, and puts forth a new, transdisciplinary theory and vocabulary of scale, one that links the natural sciences, humanities, and social sciences. In this ambitious work, scale becomes a foundation for rethinking the relationships between knowledge, mediation, and environment. (shrink)

Fourteen newly commissioned essays trace the historical development of the distinction between primary and secondary qualities, which lies at the intersection of issues in metaphysics, epistemology, and philosophy of perception. 'Primary and Secondary Qualities' focuses on the age of the Scientific Revolution, the 'locus classicus' of the distinction, but begins with chapters on ancient Greek and Scholastic accounts of qualities in an effort to identify its origins. The remainder of the volume is devoted to philosophical reflections on qualities from the (...) seventeenth century to the present day. Virtualliy every major figure is represented from Gassendi to Kant, and special attention is paid to Locke, Descartes, and Hume. The essays collected here cover a wide range of topics, including the foundation for the distinction, the question of whether it is lmetaphysical or merely epistemic, the status of secondary qualities, the nature of sensoriy representation, the relation between philosophy and science, the status of dispositions, and the semantics of sensible-quality terms"--Publisher's description, p.

We present a family of counter-examples to David Christensen's Independence Criterion, which is central to the epistemology of disagreement. Roughly, independence requires that, when you assess whether to revise your credence in P upon discovering that someone disagrees with you, you shouldn't rely on the reasoning that lead you to your initial credence in P. To do so would beg the question against your interlocutor. Our counter-examples involve questions where, in the course of your reasoning, you almost fall for an (...) easy-to-miss trick. We argue that you can use the step in your reasoning where you caught the trick as evidence that someone of your general competence level likely fell for it. Our cases show that it's permissible to use your reasoning about disputed matters to disregard an interlocutor's disagreement, so long as that reasoning is embedded in the right sort of explanation of why she finds the disputed conclusion plausible, even though it's false.

Aristotle's theory of moral character focuses on developing virtues, the deep internal dispositional traits from which external actions naturally flow. Aristotle describes moral virtue as a human excellence that can be developed through practice. The morally worst person is the vicious person who does the wrong thing, desires the wrong thing, and doesn't even know the right thing to do—perhaps even mistaking the wrong thing to do for the right thing. This was the sort of person Eleanor was when she (...) entered The Good Place. One objection to the possibility of moral development is called situationism: the claim that people don't really live according to moral character but are overwhelmingly shaped by the situations around them. As Eleanor learns in The Good Place, the road to being a better person starts with caring about those close to us. (shrink)

BackgroundThe rating of perceived exertion scales with respiratory and muscular illustrations are recognized as simple and practical methods to understand individual psychometric characteristics in breathing and muscle exertion during exercise. However, the implementation of respiratory and muscular RPE to quantify training load in futsal training camps has not been examined. This study investigates respiratory and muscular RPE relationships during domestic training camps and overseas training camps in an under 20 futsal national team.MethodsData collected from eleven field players were used for (...) comparison in this study. All players reported Borg CR10 RPE and 7-scales respiratory RPE and muscular RPE after training sessions and matches. Additionally, total distance covered and training impulse were used to quantify external and internal loads via the Polar Team Pro system. Paired-sample t-tests were used to compare the RPECR10, RPErespiration, RPEmuscle, TD, and TRIMP between DTC and OTC. Furthermore, linear regression was performed to determine the relationships among all RPE scales, TD, and TRIMP.ResultsThe RPECR10, TD, and TRIMP showed significant difference between DTC and OTC. Furthermore, linear regression analyses showed significant correlation between RPErespiration and RPEmuscle, RPECR10 and RPErespiration, and RPECR10 and RPEmuscle.ConclusionPictorial RPErespiration or RPEmuscle can be used as an alternative to quantify perceived measures of internal loads during DTC and OTC in futsal players. Interpretation of perceived measures of training load and cardiac-related responses in association with external training loads during short-term training camps would be useful in further understanding the demands of futsal players’ experience in these circumstances.

The Philosophy of Christopher Nolan collects sixteen essays written by philosophers and film theorists analyzing moral, metaphysical, epistemological, and political themes that characterize the films of Christopher Nolan.

Reasoning about situations we take to be impossible is useful for a variety of theoretical purposes. Furthermore, using a device of impossible worlds when reasoning about the impossible is useful in the same sorts of ways that the device of possible worlds is useful when reasoning about the possible. This paper discusses some of the uses of impossible worlds and argues that commitment to them can and should be had without great metaphysical or logical cost. The paper then provides an (...) account of reasoning with impossible worlds, by treating such reasoning as reasoning employing counterpossible conditionals, and provides a semantics for the proposed treatment.

Moral encroachment is the thesis that morality has an effect---unrecognized by traditional epistemology---on which doxastic states are epistemically appropriate. The thesis is increasingly popular among those who, in opposition to Gendler (2011), desire harmony between epistemic and moral demands on belief. This paper has three main goals. First, drawing on attractive structural principles concerning belief and justification, it is shown that a thoroughgoing harmony between moral and epistemic demands is implausible. This weakens the motivation for positing moral encroachment, but a (...) proponent might still hope that moral encroachment can have a significant effect, so that many of the central cases of apparent disharmony can be avoided. The next goal of the paper is to argue that any significant effect of moral encroachment would manifest itself in the credences which are most epistemically appropriate. Finally, it is shown that even a small effect of moral encroachment on credence is in tension with widely accepted basic constraints on epistemically appropriate credence. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:How Can Satan Cast Out Satan? Violence and the Birth of the Sacred in Christopher Nolan’s The Dark Knight1Nicholas Bott (bio)Last Summer, Christopher Nolan’s final installment of the Batman trilogy hit theaters. The Dark Knight Rises promised to be the epic conclusion of a hero’s journey, a journey of a man’s transformation into a legend. Little was revealed in the official trailers, except that evil was rising (...) in Gotham City, and so too must The Batman. But in this essay I’d like to suggest that we didn’t need to view The Dark Knight Rises before seeing either evil, or Batman rise; by the end of the second film, evil and Batman have already risen—and together—in the sacred form of The Dark Knight.This essay first elucidates how Bruce Wayne’s strategy to inspire good among the citizens of Gotham, first articulated in Batman Begins, encompasses the hallmarks of Girard’s mimetic theory, including: mimesis, rivalry, scandal, and, finally, the outworking of the mimetic mechanism of the surrogate victim—the scapegoat. Next, this essay takes a closer look at the goodness, or lack thereof, of Batman’s climactic self-sacrifice with its attendant resolution. Finally, this essay demonstrates that interpretations [End Page 239] of Batman’s self-sacrifice in the movie have mirrored the disparate interpretations of Christ’s self-sacrifice, in relation to the climax and resolution of the Passion accounts.Mimetic Structure in Bruce Wayne’s StrategyBeginning With the EndThe final visual the audience is given in The Dark Knight is of Batman escaping on his Batpod. The screenplay’s description of this final scene reads: “The batpod streaks through Gotham’s underground streets, the Batman’s cape fluttering behind. A wraith...”; (TDK, 140).2 Commissioner Gordon’s voice is overheard saying, “... He’s not our hero. He’s a silent guardian, a watchful protector, a dark knight” (TDK, 140). Bruce Wayne has sacrificed himself for the sake of Gotham. But what kind of sacrifice has he made?3 In the words of Alfred, “The sacrifice he’s making [is]—to not be a hero. To be something more” (TDK, 73). And Batman has become something more. No longer a hero, the language Commissioner Gordon uses to describe Batman on behalf of Gotham is mythical and sacred. Girard understands this sacralization to be the completion of the surrogate victim mechanism, the satanic process whereby the sacrifice of an innocent scapegoat reconciles a community in the midst of crisis and violent upheaval.4 This sacred vision of Batman represents the final stage of the surrogate victim mechanism, providing evidence that the satanic has been at work. But if this is the case, something has gone terribly awry in Bruce Wayne’s strategy to inspire good. With this conclusion in mind, the flaws in Wayne’s strategy as it develops throughout Batman Begins and The Dark Knight become apparent, and correspond with each step in the mimetic process.Mimesis as PlotMimesis, or imitation, stands at the heart of The Dark Knight’s plot because it stands at the heart of Bruce Wayne’s strategy to inspire good. We encounter this strategy in Nolan’s first film, Batman Begins, as Wayne explains to Alfred his reasons for returning to Gotham City:Alfred:Are you coming back to Gotham for long, sir? [End Page 240]Bruce:As long as it takes. I want to show the people their city doesn’t belong to the criminals and the corrupt.Alfred:In the depression, your father nearly bankrupted Wayne Enterprises combating poverty. He believed his example could inspire the wealthy of Gotham to save their city.Bruce:Did it?Alfred:In a way. Their murder shocked the wealthy and the powerful into action.Bruce:People need dramatic examples to shake them out of apathy. I can’t do that as Bruce Wayne. As a man... I’m flesh and blood, I can be ignored, destroyed. But as a symbol... As a symbol, I can be incorruptible. I can be everlasting.Alfred:What symbol?Bruce:Something elemental, something terrifying.(Batman Begins)5By invoking the symbolic, Bruce Wayne believes Batman will be... (shrink)

In the heart of southeast Texas, an industrial powerhouse often referred to as the 'Golden Triangle', the oil refineries and petrochemical plants stand as stalwart testaments to the region's economic evolution. Interestingly, before the discovery of oil at Spindletop, the lumber and cattle industries powered this region's economy. A profound shift occurred when the Lucas Gusher, a fountain of oil spurting thousands of feet into the air, struck the lands of Spindletop Hill on January 10, 1901. This remarkable discovery of (...) the Spindletop oilfield on a slat dome formation south of Beaumont, Texas, marked the birth of the modern petroleum industry and fundamentally transformed the region's geopolitical, economic, and cultural landscapes. People from all over the country relocated to Gladys City and Beaumont in search of work and new opportunities, creating a boomtown as the town's population swelled from 10,000 to 50,000. The newfound urbanization brought by the oil industry transformed the town and the surrounding areas, creating a ripple effect across the region that would be felt for generations to come. The surge in oil-driven economic activity transmuted the region into a vibrant nexus of commerce, with the oil industry emerging as a critical architect of growth and advancement. This newfound affluence incited by the petroleum sector ushered in an era of economic diversification, laying the groundwork for industrialization’s further evolution. The Spindletop Oil Fields not only underscored the United States’ ascent as the foremost petroleum-producing nation but also signaled the nation’s initiation into the Petroleum Age. It was Spindletop that solidified its position as America’s first significant oil field, becoming an enduring symbol of its industrial might. By 1985, over 153,000,000 barrels of oil had been produced and extracted from the Spindletop oil fields, underscoring the magnitude of this extraordinary resource. (shrink)

(Goodsell, Journal of Philosophical Logic, 51(1), 127-150 2022) establishes the noncontingency of sentences of first-order arithmetic, in a plausible higher-order modal logic. Here, the same result is derived using significantly weaker assumptions. Most notably, the assumption of rigid comprehension—that every property is coextensive with a modally rigid one—is weakened to the assumption that the Boolean algebra of properties under necessitation is countably complete. The results are generalized to extensions of the language of arithmetic, and are applied to answer a question (...) posed by Bacon and Dorr (2024). (shrink)

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

Moral fictionalism is the doctrine that the moral claims we accept should be treated as convenient fictions. One standard kind of moral fictionalism maintains that many of the moral claims we ordinarily accept are in fact false, but these claims are still useful to produce and accept, despite this falsehood. -/- Moral fictionalists claim they can recover many of the benefits of the use of moral concepts and moral language, without the theoretical costs incurred by rivals such as moral realism (...) or traditional moral noncognitivism.

It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, (...) turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.

Doxastic normativism is the thesis that norms are constitutive of or essential to belief, such that no mental state not subject to those norms counts as a belief. A common normativist view is that belief is essentially governed by a norm of truth. According to Krister Bykvist and Anandi Hattiangadi, truth norms for belief cannot be formulated without unpalatable consequences: they are either false or they impose unsatisfiable requirements on believers. I propose that we construe the fundamental norm of belief (...) as a knowledge norm, rather than a truth norm. I argue that a specific kind of knowledge norm—one that has a subject's obligation to believe that p depend on her being in a position to know that p—might avoid the well-known formulation problems with truth norms.

Assyriologists who have studied Mesopotamian commentary formation have drawn upon ideas from scholars of religion in treating the creation of a static canon at the end of the second millennium bce as a necessary precondition for the emergence of cuneiform commentaries. The present contribution argues against the idea that Mesopotamian commentaries emerged in response to a closed canon by marshaling evidence from Mesopotamian divinatory compositions, including the celestial-divinatory series Enūma Anu Enlil and its associated aḫû, or “extraneous” tradition, as well (...) as the extispical treatise Bārûtu. These compositions illustrate that commentaries could be written about texts that were still fluid and malleable in ancient Mesopotamia. Moreover, a brief look at the phenomenon of inner biblical exegesis in the Hebrew Bible supports the idea that texts need not be unchanging to be the subject of interpretation, whether in ancient Mesopotamia or elsewhere. In response to these conclusions, I outline an alternate theory for Mesopotamian commentary formation that eschews the importance of a closed canon and stresses instead ideas of scholarly bilingualism, divination, authority, and textual decorum in ancient Iraq.

Normativists about belief hold that belief formation is essentially rule- or norm-guided. On this view, certain norms are constitutive of or essential to belief in such a way that no mental state not guided by those norms counts as a belief, properly construed. In recent influential work, Kathrin Glüer and Åsa Wikforss develop novel arguments against normativism. According to their regress of motivations argument, not all belief formation can be rule- or norm-guided, on pain of a vicious infinite regress. I (...) argue that the regress of motivations argument is unsuccessful: an appeal to the notion of blind rule-following, drawn from a plausible interpretation of Ludwig Wittgenstein’s remarks on rule-following, stops the regress of motivations in its tracks.
