Coral bleaching has impacted reefs worldwide and the predictions of near‐annual bleaching from over two decades ago have now been realized. While technology currently provides the means to predict large‐scale bleaching, predicting reef‐scale and within‐reef patterns in real‐time for all reef users is limited. In 2020, heat stress across the Great Barrier Reef underpinned the region's third bleaching event in 5 years. Here we review the heterogeneous emergence of bleaching across Heron Island reef habitats and discuss the oceanographic drivers that (...) underpinned variable bleaching emergence. We do so as a case study to highlight how reef end‐user groups who engage with coral reefs in different ways require targeted guidance for how, and when, to alter their use of coral reefs in response to bleaching events. Our case study of coral bleaching emergence demonstrates how within‐reef scale nowcasting of coral bleaching could aid the development of accessible and equitable bleaching response strategies on coral reefs.

Game-theoretic explanations of behavior need supplementation to be descriptive; behavior has multiple causes, only some governed by traditional rationality. An evolutionarily informed theory of action countenances overlapping causal domains: neurobiological, psychological, and rational. Colman's discussion is insufficient because he neither evaluates learning models nor qualifies under what conditions his propositions hold. Still, inability to incorporate emotions in axiomatic models highlights the need for a comprehensive theory of functional rationality.

Imaginative resistance refers to cases in which one’s otherwise flexible imaginative capacity is constrained by an unwillingness or inability to imaginatively engage with a given claim. In three studies, we explored which specific imaginative demands engender resistance when imagining morally deviant worlds and whether individual differences in emotion predict the degree of this resistance. In Study 1 (N = 176), participants resisted the notion that harmful actions could be morally acceptable in the world of a narrative regardless of the author’s (...) claims about these actions but did not resist imagining that a perpetrator of harm could believe their actions to be morally acceptable. In Study 2 (N = 167) we replicated the findings of Study 1 and showed that imaginative resistance is greatest among participants who experience more negative affect in response to imagining harm and are lower in either trait anxiety or trait psychopathy. In Study 3 (N = 210) we show that this is the case even when the harms assessed include both low-severity (i.e., emotional harm) and high-severity (i.e., killing) cases. Thus, people’s moral beliefs constrain their ability to imagine hypothetical moral alternatives, although this ability systematically varies on the basis of stable individual differences in emotion.

In Natural Ethical Facts William Casebeer argues that we can articulate a fully naturalized ethical theory using concepts from evolutionary biology and cognitive science, and that we can study moral cognition just as we study other forms of cognition. His goal is to show that we have "softly fixed" human natures, that these natures are evolved, and that our lives go well or badly depending on how we satisfy the functional demands of these natures. Natural Ethical Facts is a (...) comprehensive examination of what a plausible moral science would look like.Casebeer begins by discussing the nature of ethics and the possible relationship between science and ethics. He then addresses David Hume's naturalistic fallacy and G. E. Moore's open-question argument, drawing on the work of John Dewey and W. V. O. Quine. He then proposes a functional account of ethics, offering corresponding biological and moral descriptions. Discussing in detail the neural correlates of moral cognition, he argues that neural networks can be used to model ethical function. He then discusses the impact his views of moral epistemology and ontology will have on traditional ethical theory and moral education, concluding that there is room for other moral theories as long as they take into consideration the functional aspect of ethics; the pragmatic neo-Aristotelian virtue theory he proposes thus serves as a moral "big tent." Finally, he addresses objections to ethical naturalism that may arise, and calls for a reconciliation of the sciences and the humanities. "Living well," Casebeer writes, "depends upon reweaving our ethical theories into the warp and woof of our scientific heritage, attending to the myriad consequences such a project will have for the way we live our lives and the manner in which we structure our collective moral institutions.".

In lieu of an abstract, here is a brief excerpt of the content:What Do You Mean, Rhetoric Is Epistemic?William D. HarpineIn 1967, Robert L. Scott (1967) advocated that "rhetoric is epistemic." This concept has enriched the work of rhetorical theorists and critics. Scott's essay is founded in a concept of argumentative justification in rhetoric, viewed as an alternative to analytic logic. Other writers, including Brummett (1976), Railsback (1983), and Cherwitz and Hikins (1986), have offered variations on Scott's theme. The (...) thesis that rhetoric is epistemic has been controversial, however, and from the tone of the debate one may draw two conclusions: many rhetorical theorists feel that Scott was on to something important, and the thesis as it has been developed is flawed. Much of the dispute centers on what the thesis means. These discussions have not yet adequately clarified that issue.The philosopher's most fundamental obligation is to define terms with care. It is in precisely this respect that the rhetoric-is-epistemic theorists have fallen short. Some of the key terms in this literature include rhetoric, knowledge, certainty, and truth. In too many cases, the writers on rhetorical epistemology have not defined their key terms at all. In other cases, their definitions are inadequate or inconsistent. This essay undertakes to sort out the most important definitional problems, which center on the rhetoric-is-epistemic theorists' habit of equivocating about the meanings of "rhetoric" and "certainty." The result makes it possible to endorse the validity of Scott's essentially ethical conclusions, while dismissing a number of unnecessary complexities in the arguments made by rhetoric-as-epistemic theorists. Finally, a few alternatives that might lead to more robust foundations for the rhetoric-as-epistemic thesis are suggested.In 1978, after reviewing four distinct interpretations of the claim that rhetoric is epistemic, Leff concluded that clarification of what that claim means "deserves more disciplined treatment than it has received in the recent literature" (1978, 77). The same could still be said. After some [End Page 335] thirty years of active research and speculation on the topic, one now sees fewer publications specifically advocating that rhetoric is epistemic. The distinguished rhetorical theorist Barry Brummett (1990) has declared the thesis deceased (69-72).All the same, textbook authors treat the thesis as a given, despite their tendency to interpret it in wildly different ways. Foss, for example, puts forward a view that "in the field of communication, the idea that rhetoric creates reality is known as the notion that rhetoric is epistemic, which simply means that rhetoric creates knowledge; epistemology is the study of the origin and nature of knowledge" (1989, 122; emphasis in the original). This version of the thesis, claiming that rhetoric actually "creates reality," might be more ontological than it is epistemic.1 Herrick takes a dialectical view that "through rhetorical interaction, people come to accept some ideas as true and to reject others as false. Thus, rhetoric's epistemic function in society can be seen in some ways to be a result of its benefit of testing ideas." Herrick continues that "once an idea has been tested thoroughly by a group, community, and society, it becomes part of what these groups take to be knowledge." Herrick contrasts this with the rejected view that "knowledge is all objective in nature and comes to us by way of direct experience or education" (1997, 22). Both Herrick and Foss offer interesting theses, and both attribute their views to Scott, but their views are obviously very different. There can be no surer evidence of the failure to use terms precisely.Brummett (1990) attributes the demise of rhetoric-is-epistemic research to the failure of critics to employ the idea in rhetorical criticism. Brummett might be right to the extent that much of the rhetoric-is-epistemic literature is indeed exceptionally abstract. Specific discussions might clarify some issues. Nonetheless, some notable rhetorical critics have indeed employed a concept that rhetoric is epistemic (e.g., Scott and Klumpp 1984; Sullivan 1992). The issues remain unclear. Furthermore, rhetorical criticism per se cannot clarify the meanings of theoretical terms. More likely, one sees less and less published research about the thesis that rhetoric is epistemic precisely because the thesis has not been laid out clearly... (shrink)

Cet article a comme objetif analyser les liens possibles entre deux thèmes de grande relevance de la philosophie de Nicolas de Cues : la théophanie comme manifestation de Dieu et la filiatione dei ou visio Dei, comme modes de clairvoyance de l'infini divin. Cette « voie divine » de la connaissance est la fin d'un voyage où la créature « court » vers le fondement radical qui se révèle em tant que présence infinie dans le fini grâce une « vision (...) » intellectuelle. Le principe de la non-contradiction doit donc être remplacé par celui de la coïncidence des contraires ; cependant, ce dernier doit finalement être dépassé par l'ignorance savante. A son tour, selon Nicolas de Cues, dans cette vision théophanique, le « ne pas savoir » de la créature coincide avec le « savoir » que Dieu a de lui-même, c'est-à-dire de sa connaissance de soi comme infini et non pas en tant qu’une chose parmi d’autres. Dans la tradition néoplatonicienne latine, l’univers théorique où gravitent les concepts de monè, proódos et epistrophé (manence, procession et retour), Nicolas de Cues apporte cependant des nouveautés par rapport à ses prédécesseurs, comme Jean Scot Erigène, puisqu'il se lance dans une tentative ambitieuse d’utiliser la négativité comme outil d'un « discours ignorant » radical, c'est-à-dire un discours qui cherche une expression positive de la « racine » de cette relation paradoxale Créateur-créature. A travers l'itinéraire d'élaboration des noms divins et des énigmes de plus en plus « capables » d'orienter l'intellect vers cette vision du principe incompréhensible dans sa relation active de création/vision avec l'Univers, le Cardinal parcourt le chemin philosophique proposé dans son De coniecturis : une recherche sans fin de l'expression positive de Dieu à travers la négativité visant dépasser l’anonymat classique qui caractérise la tradition néoplatonicienne. Mots-clés : Nicolas de Cues, Visio de Dieu, Docte ignorance, infini, néoplatonisme. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Bernard Williams charges that the moral psychology built into R. M. Hare’s utilitarianism is incoherent in virtue of demanding a bifurcated kind of moral thinking that is possible only for agents who fail to reflect properly on their own practical decision making. I mount a qualified defence of Hare’s view by drawing on the account of the ‘reactive attitudes’ found in P. F. Strawson’s ‘Freedom and Resentment’. Against Williams, I argue that the ‘resilience’ of the reactive attitudes ensures that our (...) taking an instrumental view of our dispositions to experience guilt and compunction, as Hare calls for us to do while engaged in ‘critical’ moral thinking, will not prevent us from experiencing these feelings as people ordinarily do while we are thinking ‘intuitively’. I also consider the implications of my argument for consequentialism more generally and (briefly) Kantianism. (shrink)

An objection to reductionism in the epistemology of testimony that is often repeated but rarely defended in detail is that there is not enough positive evidence to provide the non-testimonial, positive reasons reductionism requires. Thus, on pain of testimonial skepticism, reductionism must be rejected. Call this argument the ‘Not Enough Evidence Objection’. I will defend reductionism about testimonial evidence against the NEEO by arguing that we typically have non-testimonial positive reasons in the form of evidence about our testifier's evidence. With (...) a higher-level evidence principle borrowed from recent work on the epistemology of disagreement, I argue that, granting some plausible assumptions about conversational norms, the NEEO is unsound.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Merleau-Ponty spent the summer of 1960 in the small French village of Le Tholonet writing Eye and Mind. His choice of location was no accident. Le Tholonet was the physical and emotional epicenter of Paul Cezanne’s late painting, the ultimate proving ground of his relentless quest to reveal the truth of landscape in art.It makes perfect sense that Merleau-Ponty wrote Eye and Mind in Le Tholonet. The essay is a philosophical meditation on vision and painting. But it also is a (...) meditation on place, in the deeply saturated sense that encompasses the landscape, its natural and human history, and the history of the painter who brought this part of Provence to universal visibility in his art. Le Tholonet is the terroir of Eye and Mind, the site and soil of this final, extraordinary expression of Merleau-Ponty’s thinking. Merleau-Ponty passa l’été 1960 dans le petit village français de Le Tholonet en écrivant L’OEil et l’Esprit. Le choix de ce lieu n’est pas accidentel. Le Tholonet était l’épicentre physique et émotionnel de la dernière peinture de Paul Cézanne, le terrain d’essai final de sa quête incessante pour arriver à révéler la vérité du paysage dans l’art. C’est tout à fait sensé que Merleau-Ponty ait écrit L’OEil et l’Esprit à Le Tholonet. L’essai est une méditation philosophique sur la vision et sur la peinture. Mais c’est aussi une méditation sur le lieu, sur le sens profondément saturé qui entoure le paysage, sur son histoire naturelle et humaine, et sur l’histoire du peintre qui porta, par son art, ce coin de la Provence à la visibilité universelle. On pourrait alors dire que Le Tholonet est le terroir de L’OEil et l’Esprit, le site et le sol de cette expression finale et extraordinaire de la réflexion de Merleau-Ponty. Merleau-Ponty trascorse l’estate del 1960 nel piccolo villaggio francese di Le Tholonet, dedicandosi alla scrittura de L’occhio e lo spirito. La scelta di questo luogo non fu casuale. Le Tholonet fu infatti l’epicentro fisico ed emotivo della pittura dell’ultimo Cézanne, il campo di prova finale del suo tentativo instancabile di rivelare la verità del paesaggio nell’arte. È del tutto coerente che Merleau-Ponty abbia scritto L’occhio e lo spirito a Le Tholonet. Il saggio costituisce una riflessione filosofica sulla visione e sulla pittura, ma rappresenta anche una meditazione sul senso di un luogo, secondo un’accezione densa che comprende il paesaggio, la sua storia naturale e umana, e la storia del pittore che attraverso la sua arte ha portato questa parte della Provenza a una visibilità universale. Le Tholonet è il terroir de L’occhio e lo spirito, il sito che ospita e il terreno che nutre quest’ultima straordinaria espressione del pensiero di Merleau-Ponty. (shrink)

The Appeal to Tradition, often considered to be unsound, frequently reflects sophisticated adaptations to the environment. Once developed, these adaptations are often transmitted culturally rather than as reasoned argument, so that people mayor may not be aware of why their traditions are wise. Tradition is more likely to be valid in a stable environment in which a wide range of variations have been available for past testing; however, traditions tend to become obsolete in a rapidly changing environment.

As scientific and engineering efforts become increasingly global in nature, the need to understand differences in perceptions of research ethics issues across countries and cultures is imperative. However, investigations into the connection between nationality and ethical decision-making in the sciences have largely generated mixed results. In Study 1 of this paper, a measure of biases and compensatory strategies that could influence ethical decisions was administered. Results from this study indicated that graduate students from the United States and international graduate students (...) studying in the US are prone to different biases. Based on these findings, recommendations are made for developing ethics education interventions to target these decision-making biases. In Study 2, we employed an ethics training intervention based on ethical sensemaking and used a well-established measure of ethical decision-making that more fully captures the content of ethical judgment. Similar to Study 1, the results obtained in this study suggest differences do exist between graduate students from the US and international graduate students in ethical decision-making prior to taking the research ethics training. However, similar effects were observed for both groups following the completion of the ethics training intervention. (shrink)

In the rod‐shaped cells of E. coli, chromosome segregation takes place immediately after replication has been completed. A septum then forms between the two sister chromosomes. In the absence of certain membrane proteins, cells grow instead as large, multichromosomal spheres that divide successively in planes that are at right angles to one another. Although multichromosomal, the spherical cells cannot be maintained as heterozygotes. These observations imply that, in these mutants, each individual chromosome gives rise to a separate clone of descendant (...) cells. This suggests a model in which sites for cell division form between pairs of sister chromosomes at the time of segregation, but are not used in spherical cells until further rounds of replication have taken place, thus ensuring clonal (‘hierarchical’) segregation of chromosomes into progeny cells. The role of the morphogenetic membrane proteins is to convert the basically spherical cell into a cylinder that is able to divide as soon as replication and segregation have been completed, and thus to maximise the number of viable cells per genome.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

The paper examines constraints and preferences employed by people in learning decision rules from preclassified examples. Results from four experiments with human subjects were analyzed and compared with artificial intelligence (AI) inductive learning programs. The results showed the people's rule inductions tended to emphasize category validity (probability of some property, given a category) more than cue validity (probability that an entity is a member of a category given that it has some property) to a greater extent than did the AI (...) programs. Although the relative proportions of different rule types (e.g., conjunctive vs. disjunctive) changed across experiments, a single process model provided a good account of the data from each study. These observations are used to argue for describing constraints in terms of processes embodied in models rather than in terms of products or outputs. Thus AI induction programs become candidate psychological process models and results from inductive learning experiments can suggest new algorithms. More generally, the results show that human inductive generalizations tend toward greater specificity than would be expected if conceptual simplicity were the key constraint on inductions. This bias toward specificity may be due to the fact that this criterion both maximizes inferences that may be drawn from category membership and protects rule induction systems from developing over‐generalizations.

The thymus is a unique primary lymphoid organ that supports the production of self‐tolerant T‐cells essential for adaptive immunity. Intrathymic microenvironments are microanatomically compartmentalised, forming defined cortical, and medullary regions each differentially supporting critical aspects of thymus‐dependent T‐cell maturation. Importantly, the specific functional properties of thymic cortical and medullary compartments are defined by highly specialised thymic epithelial cells (TEC). For example, in the medulla heterogenous medullary TEC (mTEC) contribute to the enforcement of central tolerance by supporting deletion of autoreactive T‐cell (...) clones, thereby counterbalancing the potential for random T‐cell receptor generation to contribute to autoimmune disease. Recent advances have further shed light on the pathways and mechanisms that control heterogeneous mTEC development and how differential mTEC functionality contributes to control self‐tolerant T‐cell development. Here we discuss recent findings in relation to mTEC development and highlight examples of how mTEC diversity contribute to thymus medulla function. (shrink)

If we are to ensure the persistence of species in an increasingly warm world, of interest is the identification of drivers that affect the ability of an organism to resist thermal stress. Underpinning any organism's capacity for resistance is a complex interplay between biological and physical factors occurring over multiple scales. Tropical coral reefs are a unique system, in that their function is dependent upon the maintenance of a coral–algal symbiosis that is directly disrupted by increases in water temperature. A (...) number of physical factors have been identified as affecting the biological responses of the coral organism under broadscale thermal anomalies. One such factor is water flow, which is capable of modulating both organismal metabolic functioning and thermal environments. Understanding the physiological and hydrodynamic drivers of organism response to thermal stress improves predictive capabilities and informs targeted management responses, thereby increasing the resilience of reefs into the future.

This study examines how codes of conduct, monitoring, and penalties for dishonest reporting affect reporting honesty in an online labor market setting. Prior research supports the efficacy of codes of conduct in promoting ethical behavior in a variety of contexts. However, the effects of such codes and other methods have not been examined in online labor markets, an increasingly utilized resource that differs from previously examined settings in several key regards (e.g., transient workforce, lack of an established culture). Leveraging social (...) norm activation theory, we predict and find experimental evidence that while codes of conduct and monitoring without economic penalties are ineffective in online settings, monitoring with economic penalties activates social norms for honesty and promotes honest reporting in an online setting. Further, we find that imposing penalties most effectively promotes honest reporting in workers who rate high in Machiavellianism, a trait that is highly correlated with dishonest reporting. In fact, while in the absence of penalties we observe significantly more dishonest reporting from workers who rate high versus low in Machiavellianism, this difference is eliminated in the presence of penalties. Implications of these findings for companies, researchers, online labor market administrators, and educators are discussed. (shrink)

Most words in English are ambiguous between different interpretations; words can mean different things in different contexts. We investigate the implications of different types of semantic ambiguity for connectionist models of word recognition. We present a model in which there is competition to activate distributed semantic representations. The model performs well on the task of retrieving the different meanings of ambiguous words, and is able to simulate data reported by Rodd, Gaskell, and Marslen‐Wilson [J. Mem. Lang. 46 (2002) 245] on (...) how semantic ambiguity affects lexical decision performance. In particular, the network shows a disadvantage forwords with multiple unrelated meanings (e.g., bark) that coexists with a benefit for words with multiple related word senses (e.g., twist). The ambiguity disadvantage arises because of interference between the different meanings, while the sense benefit arises because of differences in the structure of the attractor basins formed during learning. Words with few senses develop deep, narrow attractor basins, while words with many senses develop shallow, broad basins. We conclude that the mental representations of word meanings can be modelled as stable states within a high‐dimensional semantic space, and that variations in the meanings of words shape the landscape of this space.
