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.

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.

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)

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)

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.

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)

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.

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)

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.

Causal models of agents have been used to analyse the safety aspects of machine learning systems. But identifying agents is non-trivial -- often the causal model is just assumed by the modeler without much justification -- and modelling failures can lead to mistakes in the safety analysis. This paper proposes the first formal causal definition of agents -- roughly that agents are systems that would adapt their policy if their actions influenced the world in a different way. From this we (...) derive the first causal discovery algorithm for discovering agents from empirical data, and give algorithms for translating between causal models and game-theoretic influence diagrams. We demonstrate our approach by resolving some previous confusions caused by incorrect causal modelling of agents. (shrink)

Urban infrastructures serve as the backbone of modern economies, mediating global exchanges and responding to urban demands. Yet, our comprehension of these complex structures, particularly within diverse socio-political terrain, remains fragmented. In bridging this knowledge gap, this study delves into “boundary objects”—entities enabling diverse stakeholders to collaborate without a comprehensive consensus. Central to our investigation is the hypothesis that oceanic infrastructural developments are instrumental in molding the interface of urban, industrial, and energy sectors within marine contexts. Our lens is directed (...) at the Gulf of Mexico, which is distinguished by its industrial depth and expansive marine grid. We highlight the Gulf Intracoastal Waterway’s (GIWW) paramount role in regional movement and the ecological facets of practices such as dredging, which is vital for transport and coastal conservation. A striking revelation of our study is the transformation of offshore structures in the Gulf into vibrant marine habitats. Emphasizing the intertwined nature of marine infrastructures, we denote oceans as pivotal platforms for impending urban expansion, especially as land resources wane. Our research aspires to validate the role played by oceans as a nexus in the urban–industrial–energy fusion. (shrink)

Descartes maintains that we can love God and that it is pleasant and morally beneficial to do so. In this essay, I examine the necessary conditions for such an intellectual love of God. I argue that the intellectual love of God is incited by a judgment that we are joined to God in reality, which is constitutive of an intellectual joy. I go on to show that the intellectual love of God is, itself, constituted by a stripping of our private (...) interests in favor of God’s divine will. (shrink)

Research on economization processes is increasingly taking seriously the social and material processes through which various policy domains are transformed into economic problems and solutions. This article engages “Value Added Modeling” (VAM) in teacher evaluation systems as a case study in economization. VAM is a statistical technology for evaluating the effectiveness of schoolteachers using student test scores, which wrests authority for the determination of quality teaching away from education professionals and toward quantitative economic modelers. Mobilizing field theory, we trace a (...) half century of changing relationships among economists, other academics, and various policy audiences (from media to philanthropists to state and federal government) in struggles to define education policy concerning teacher quality. We show that economization is a set of overlapping, sometimes contradictory processes that can take different forms: in this case, the spread of an “economic style of reasoning” or the establishment of “economic policy devices.” The case of VAM shows stages of economization in which processes first proceeded independently of one another, then interacted in contradictory ways, and finally, mutually reinforced one another. What primarily drove these interactions was the struggle for scientific capital within the economics discipline and the changing place of education policy and VAM within it. Ultimately, VAM’s original role as a policy device for evaluating and selecting individual teachers has foundered even as it has become an important tool for economists to accrue scientific capital and expand their style of reasoning to broader audiences.

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.

Arguments from Silence have been used many times in attempts to discredit the foundations of religions. In this project, I demonstrate how one might judge the epistemic value of such arguments.

I then discuss a recently developed Bayesian approach for dealing with arguments from silence. Finally, using Cassels’s work and the work of some of the critics who replied (...) to his argument, I argue for what probabilities might be applied in the use of the Bayesian method for testing the epistemic value Cassels’s argument and demonstrate how one might respond to similar arguments.

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.

Paul Griffiths and John Matthewson argue that selected effects play the key role in determining whether a state is pathological. In response, it is argued that a selected effects account faces a number of difficulties in light of modern genomic research. Firstly, a modern history approach to selection is problematic as a basis for assigning function to human traits in light of the small population sizes in the hominin lineage, which imply that selection has played a limited role in shaping (...) these genomes in the evolutionarily recent past. Secondly, determining both the genetic basis of disease and selective histories of the various alleles involved may be experimentally intractable. Thirdly, the existence of “selected disorders” is well supported, and yet on the other hand many other common diseases may not reduce evolutionary fitness. In summary, the biological ends promoted by natural selection, as best modeled in recent research, do not adequately ground a concept of dysfunction that aligns well with the interests of human health.

The propensity interpretation of fitness (PIF) holds that evolutionary fitness is an objectively probabilistic causal disposition (i.e., a propensity) toward reproductive success. I characterize this as the conceptual foundation of the PIF. Reproductive propensities are meant to explain trends in actual reproductive outcomes. In this paper, I analyze the minimal theoretical and ontological commitments that must accompany the explanatory power afforded by the PIF’s foundation. I discuss three senses in which these commitments are less burdensome than has typically been recognized: (...) the PIF’s foundation is (i) compatible with a principled pluralism regarding the mathematical relationship between measures of individual and trait reproductive success; (ii) independent of the propensity interpretation of probability; and (iii) independent of microphysical indeterminism. The most substantive ontological commitment of the PIF’s foundation is to objective modal structures wherein macrophysical probabilities and causation can be found, but I hedge against metaphysically inflationary readings of this modality.

A semantic theory aims to make predictions that are accurate and comprehensive. Sometimes, though, a semantic theory falls short of this aim, and there is a mismatch between prediction and data. In such cases, defenders of the semantic theory often attempt to rescue it by appealing to Gricean pragmatics. The hope is that we can rescue the theory as long as we can use pragmatics to explain away its predictive failures. This pragmatic rescue strategy is one of the most popular (...) moves in philosophy of language, philosophical logic, and formal semantics. In this paper I argue that this strategy fails whenever the predictive failures at issue can be recast in epistemological or metaphysical terms. This general “reformulation argument” undermines a wide variety of pragmatic rescue attempts. (shrink)

Individualist normative theories appear inadequate for the complex moral challenges of climate change. In climate ethics, this is especially notable with the relative marginalization of Kant. I argue that Kant’s philosophy, understood through its historical and cosmopolitan dimensions, has untapped potential for the climate crisis. First, I situate Kant in climate ethics and evaluate his marginalization due to perceived individualism, interiority and anthropocentrism. Then, I explore aspects of Kant’s historical and cosmopolitan writings, which present a global, future-orientated picture of humanity. (...) Ultimately, Kant’s philosophy offers a unique take on the climate deadlock capable of sustaining the individual in the collective. (shrink)

Recently, Christine Bratu and Mortiz Dittmeyer have argued that Christine Korsgaard’s constitutive project fails to establish the normativity of practical principles because it fails to show why a principle’s being constitutive of a practice shows that one ought to conform to that principle. They argue that in many cases a principle’s being constitutive of a practice has no bearing on whether one ought to conform to it. In this paper I argue that Bratu and Dittmeyer’s argument fails in three important (...) respects. First, they fail to recognize the ways in which Korsgaard’s neo-Kantian view departs from more orthodox Kantian views. Second, they fail to recognize the respect in which Korsgaard’s view is a version of moral rationalism. Third, they overlook an important scope ambiguity in an important premise of their argument. A sensible way of resolving this ambiguity gives the constitutivist a reasonable response. (shrink)

For decades, scholars in the social sciences and humanities have questioned the appropriateness and utility of prior review of their research by human subjects' ethics committees. This essay seeks to organize thematically some of their published complaints and to serve as a brief restatement of the major critiques of ethics review.

By recovering the dependent, often enslaved, laborers who helped to make European medicines commercially available in the New England colonies, this article offers a new history of early American pharmaceutical knowledge and production. It does so by considering the life and labor of an unnamed, enslaved assistant who was said to make tinctures, elixirs, and other common remedies in a 1758 letter between two business partners, Silvester Gardiner, a successful surgeon and apothecary in Boston, Massachusetts, and William Jepson, his former (...) apprentice, in Hartford, Connecticut. Using strategies from slavery and critical archive studies, as well as from social history and the history of medicine, this article emphasizes the materiality and embodiment of pharmaceutical production and follows fragmentary evidence beyond the business archive to reverse the systemic erasure of enslaved and indentured laborers from the records of eighteenth-century manufacturers of medicines. The medicine trades of men like Gardiner and Jepson appear more reliant upon dependent laborers – named and unnamed – who not only performed rote tasks but brought their experience and judgment to their labors as well. Their contributions could be obviously medical (preparing remedies) or more ambiguous (stoking fires, shipping goods), but these actions together constituted early modern pharmacy, enabled the expansion of the transatlantic medicine trade, and laid the foundations for the more self-sufficient and industrialized pharmacy that developed in the nineteenth century. Centering the skill and knowledge among subordinated laborers in one facet of an emergent transatlantic care economy affirms the entanglement of slavery and science and underscores the necessity of asking new questions of old sources.

A number of thinkers have been wondering about the moral obligations humans have, or will have, to intelligent technologies. An underlying assumption is that “moral machines” are decades in the offing, and thus we have no pressing obligations now. But, in the context of technology, we are yet to consider that we might owe moral consideration to something that is not a member of the moral community but eventually will be as an outcome of human action. Do we have current (...) actual obligations to technologies that do not currently exist? If there are obligations to currently non-existing technologies, we must confront what might be called the Non-Identical Machines Problem. Can we harm or benefit an entity by making it one way rather than another? This paper presents the problem and argues that it is more challenging than the standard Non-Identity Problem. (shrink)

The principle of Anteriority says that prospects that are identical from the perspective of every possible person’s welfare are equally good overall. The principle enjoys prima facie plausibility, and has been employed for various theoretical purposes. Here it is shown using an analogue of the St Petersburg Paradox that Anteriority is inconsistent with central principles of axiology.

In this paper I argue that Kant’s pre-critical ontology, though generally dismissed by environmental philosophers, provides ecological lessons by way of its metaphysical affinities with environmental philosophy. First, I reference where environmental philosophy tends to place Kant and highlight his relative marginalization. This marginalization makes sense given focus on his critical works. I then outline Kant’s pre-critical ontological framework and characterize the ways in which it is ecological. Finally, I conclude with some ecological reflections on the pre-critical philosophy and its (...) possible relevance for contemporary environmental issues. (shrink)

Although scientists dating back to Darwin have noted the importance of the body in communicating emotion, current research on emotion communication tends to emphasize the face. In this article we review the evidence for bodily expressions of emotions—that is, the handful of emotions that are displayed and recognized from certain bodily behaviors.

Although no extant coding system provides an exhaustive list of bodily behaviors known to (...) communicate a panoply of emotions, our review provides the foundation for developing such a system.

This study tested four theoretical models of leadership with data from the ethnographic record. The first was a game-theoretical model of leadership in collective actions, in which followers prefer and reward a leader who monitors and sanctions free-riders as group size increases. The second was the dominance model, in which dominant leaders threaten followers with physical or social harm. The third, the prestige model, suggests leaders with valued skills and expertise are chosen by followers who strive to emulate them. The (...) fourth proposes that in small-scale, kin-based societies, men with high neural capital are best able to achieve and maintain positions of social influence (e.g., as headmen) and thereby often become polygynous and have more offspring than other men, which positively selects for greater neural capital. Using multiple search strategies we identified more than 1000 texts relevant to leadership in the Probability Sample of 60 cultures from the Human Relations Area Files (HRAF). We operationalized the model with variables and then coded all retrieved text records on the presence or absence of evidence for each of these 24 variables. We found mixed support for the collective action model, broad support for components of the prestige leadership style and the importance of neural capital and polygyny among leaders, but more limited support for the dominance leadership style. We found little evidence, however, of emulation of, or prestige-biased learning toward, leaders. We found that improving collective actions, having expertise, providing counsel, and being respected, having high neural capital, and being polygynous are common properties of leaders, which warrants a synthesis of the collective action, prestige, and neural capital and reproductive skew models. We sketch one such synthesis involving high-quality decision-making and other computational services. (shrink)

Markosian presents an argument against certain theories of time based on the aesthetic value of music.

I do this by appealing to spatial analogies (...) that highlight the similarities between spatial and temporal rotations. (shrink)
