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.

The “American-style” class action, when combined with private rights, is an important tool of American regulatory policy. And just as American regulation has global reach, the global class action is not unfamiliar to U.S. courts. Yet, global U.S. class actions are facing ever-stronger headwinds. In addition to the recent retrenchment of class actions and international litigation generally, U.S. courts have raised additional barriers to global class actions in particular. This Article’s first goal, therefore, is to document these developments and their (...) consequences for regulation. Against this backdrop, this Article also reviews the options available to foreign lawmakers, foreign courts, foreign litigants and litigation funders, and foreign public enforcers. Foreign lawmakers may provide alternatives to global U.S. class actions; foreign courts and foreign litigants may explicitly or implicitly coordinate to approximate global class resolution; and foreign public enforcers may achieve the goals of global regulatory litigation while avoiding some of its legal impediments. Finally, this Article evaluates these various foreign responses from an institutional perspective, with special attention to the institutional incentives for lawmakers and law enforcers. (shrink)

The medical biography of Ludwig van Beethoven remains enigmatic. Some of his health problems, such as his early and eventually profound deafness, are well documented and extensively discussed, although not necessarily well explained . Other medical problems, and his ultimate cause of death, remain unclear. Perhaps unsurprisingly for such an important musical figure, there has been no dearth of speculation about the illnesses that may have befallen Beethoven. Medical historians and physicians have suggested a myriad of illnesses, including but hardly (...) limited to .. (shrink)

This book is a qualitative, interpretive, phenomenological, and interdisciplinary, examination of food and food practices and their meanings in the modern world. Each chapter thematically focuses upon a particular food practice and on some key details of the examined practice, or on the practice’s social and cultural impact.

This article focuses upon answering the following question: Does corporate political activity stand as an academic field? Following Hambrick and Chen, we consider three elements of the emergence of an academic field—differentiation, mobilization, and legitimacy. Utilizing a variety of data sources, we find CPA to be well differentiated from other academic fields; to have undertaken a number of activities to mobilize CPA as a field, but short of large-scale unification; and to have earned low to moderate legitimacy within management, (...) but little legitimacy outside of management. All in all, at this time, CPA does not squarely meet the elements necessary to emerge as a field. (shrink)

Il s'agit de l'édition d'un catalogue de 24 sceaux de plomb sélectionnés à partir d'une collection privée américaine. Cette collection contient aussi deux bullae byzantines en or inclues aux sceaux. Les deux critères de sélection employés ont été l'unicité et la rareté, qualités reconnaissables notamment pour le sceau n° 6 qui comporte une représentation du prophète Zacharie.

One of the most important recent developments in the discussion of Kierkegaard's ethics is an interpretation defended, in different forms, by Philip Quinn and Stephen Evans. Both argue that a divine-command theory of moral obligation is to be found in Works of Love . Against this view, I argue that, despite significant overlap between DCT and the view of moral obligation found in Works of Love , there is at least one essential difference between the two: the former, but not (...) the latter, is committed to the claim that, necessarily, p is morally obligatory only if God commands that p.

Philosophers, psychologists, and economists have reached the consensus that one can use two different kinds of regulation to achieve self-control. Synchronic regulation uses willpower to resist current temptation. Diachronic regulation implements a plan to avoid future temptation. Yet this consensus may rest on contaminated intuitions. Specifically, agents typically use willpower (synchronic regulation) to achieve their plans to avoid temptation (diachronic regulation). So even if cases of diachronic regulation seem to involve self-control, this may be because they are contaminated by synchronic (...) regulation. We therefore developed a novel multifactorial method to disentangle synchronic and diachronic regulation. Using this method, we find that ordinary usage assumes that only synchronic––not diachronic––regulation counts as self-control. We find this pattern across four experiments involving different kinds of temptation, as well as a paradigmatic case of diachronic regulation based on the classic story of Odysseus and the Sirens. Our final experiment finds that self-control in a diachronic case depends on whether the agent uses synchronic regulation at two moments: when she (1) initiates and (2) follows-through on a plan to resist temptation. Taken together, our results strongly suggest that synchronic regulation is the sole difference maker in the folk concept of self-control. (shrink)

It is natural for those with permissive attitudes toward abortion to suppose that, if they have examined all of the arguments they know against abortion and have concluded that they fail, their moral deliberations are at an end. Surprisingly, this is not the case, as I argue. This is because the mere risk that one of those arguments succeeds can generate a moral reason that counts against the act. If this is so, then liberals may be mistaken about the morality (...) of abortion. However, conservatives who claim that considerations of risk rule out abortion in general are mistaken as well. Instead, risk-based considerations generate an important but not necessarily decisive reason to avoid abortion. The more general issue that emerges is how to accommodate fallibilism about practical judgment in our decision-making. (shrink)

The field of `science and religion' is exploding in popularity among both academics and the reading public. This is a comprehensive and authoritative introduction to the debate, written by the leading experts yet accessible to the general reader.

Although mind-wandering occupies up to half of our waking thoughts, it is seldom discussed in philosophy. My paper brings these neglected thoughts into focus. I propose that mind-wandering is unguided attention. Guidance in my sense concerns how attention is monitored and regulated as it unfolds over time. Roughly speaking, someone’s attention is guided if she would feel pulled back, were she distracted from her current focus. Because our wandering thoughts drift unchecked from topic to topic, they are unguided. One motivation (...) for my theory is what I call the “Puzzle of the Purposeful Wanderer”. On the one hand, mind-wandering seems essentially purposeless; almost by definition, it contrasts with goal-directed cognition. On the other hand, empirical evidence suggests that our minds frequently wander to our goals. My solution to the puzzle is this: mind-wandering is purposeless in one way—it is unguided—but purposeful in another—it is frequently caused, and thus motivated, by our goals. Another motivation for my theory is to distinguish mind-wandering from two antithetical forms of cognition: absorption and rumination. Surprisingly, previous theories cannot capture these distinctions. I can: on my view, absorption and rumination are guided, whereas mind-wandering is not. My paper has four parts. Section 1 spells out the puzzle. Sections 2 and 3 explicate two extant views of mind-wandering—the first held by most cognitive scientists, the second by Thomas Metzinger. Section 4 uses the limitations of these theories to motivate my own: mind-wandering is unguided attention. (shrink)

In this article, we develop an approach for the moral assessment of research and development networks on the basis of the reflective equilibrium approach proposed by Rawls and Daniels. The reflective equilibrium approach aims at coherence between moral judgments, principles, and background theories. We use this approach because it takes seriously the moral judgments of the actors involved in R & D, whereas it also leaves room for critical reflection about these judgments. It is shown that two norms, namely reflective (...) learning and openness and inclusiveness, which are used in the literature on policy and technological networks, contribute to achieving a justified overlapping consensus. We apply the approach to a case study about the development of an innovative sewage treatment technology and show how in this case the two norms are or could be instrumental in achieving a justified overlapping consensus on relevant moral issues.

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 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. 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)

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. We also review the previously developed coding systems available for identifying emotions from 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.

Markosian presents an argument against certain theories of time based on the aesthetic value of music. He argues that turning a piece of music sideways in time destroys its intrinsic value, which would not be possible if the Spacetime Thesis were true. In this paper I show that sideways music poses no problems for any theory of time by demonstrating that turning a piece of music sideways does not affect its intrinsic value. I do this by appealing to spatial analogies (...) that highlight the similarities between spatial and temporal rotations. (shrink)

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)

The notion of an extended simple region (henceforth ESR) has recently been marshalled in the service of arguments for a variety of conclusions. Exactly how to understand the idea of extendedness as it applies to simple regions, however, has been largely ignored, or, perhaps better, assumed. In this paper we first (§1) outline what we take to be the standard way that philosophers are thinking about extendedness, namely as an intrinsic property of regions. We then introduce an alternative picture (§2), (...) according to which extendedness is extrinsic. In §3 we argue that it matters which way of thinking about extendedness is the right one, since how ESRs behave is sensitive to what extendedness consists in, and various arguments that appeal to ESRs turn out to be unsound if extendedness is extrinsic rather than intrinsic.

A large body of research has indicated international students in the United States and abroad experience difficulties understanding what academic integrity is and how to avoid academic misconduct, 159–172 2011; Brown & Howell, 2001; Gullifer and Tyson Studies in Higher Education, 39, 1202-1218 2014). While most studies focus on academic misconduct and academic corruption in research ethics, 339-358 2014), this study analyzes the length, English-language readability, and translation of academic integrity policies of 453 four-year U.S. institutions of higher education. Findings (...) indicate average academic integrity policies are over 2000 words long, are written above the 16th-grade reading level, and are very rarely translated into a language other than English. In addition, no institutions published their academic integrity policies in full on their institutional international student website, possibly rendering the policy difficult to locate on the institution’s website for international students. Implications for research, policy, and practice are addressed. (shrink)

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.

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)

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)

Morgenbesser's Coin is a thought experiment that exemplifies a widespread disposition to infer counterfactual independence from causal independence. I argue that this disposition is mistaken by analysing a closely related thought experiment.
