Language research has come to rely heavily on large‐scale, web‐based datasets. These datasets can present significant methodological challenges, requiring researchers to make a number of decisions about how they are collected, represented, and analyzed. These decisions often concern long‐standing challenges in corpus‐based language research, including determining what counts as a word, deciding which words should be analyzed, and matching sets of words across languages. We illustrate these challenges by revisiting “Word lengths are optimized for efficient communication” (Piantadosi, Tily, & Gibson, (...) 2011), which found that word lengths in 11 languages are more strongly correlated with their average predictability (or average information content) than their frequency. Using what we argue to be best practices for large‐scale corpus analyses, we find significantly attenuated support for this result and demonstrate that a stronger relationship obtains between word frequency and length for a majority of the languages in the sample. We consider the implications of the results for language research more broadly and provide several recommendations to researchers regarding best practices. (shrink)

Spoken communication occurs in a “noisy channel” characterized by high levels of environmental noise, variability within and between speakers, and lexical and syntactic ambiguity. Given these properties of the received linguistic input, robust spoken word recognition—and language processing more generally—relies heavily on listeners' prior knowledge to evaluate whether candidate interpretations of that input are more or less likely. Here we compare several broad-coverage probabilistic generative language models in their ability to capture human linguistic expectations. Serial reproduction, an experimental paradigm where (...) spoken utterances are reproduced by successive participants similar to the children's game of “Telephone,” is used to elicit a sample that reflects the linguistic expectations of English-speaking adults. When we evaluate a suite of probabilistic generative language models against the yielded chains of utterances, we find that those models that make use of abstract representations of preceding linguistic context (i.e., phrase structure) best predict the changes made by people in the course of serial reproduction. A logistic regression model predicting which words in an utterance are most likely to be lost or changed in the course of spoken transmission corroborates this result. We interpret these findings in light of research highlighting the interaction of memory-based constraints and representations in language processing. (shrink)

We will show that there is a strong form of emergence in cell biology. Beginning with C.D. Broad's classic discussion of emergence, we distinguish two conditions sufficient for emergence. Emergence in biology must be compatible with the thought that all explanations of systemic properties are mechanistic explanations and with their sufficiency. Explanations of systemic properties are always in terms of the properties of the parts within the system. Nonetheless, systemic properties can still be emergent. If the properties of the components (...) within the system cannot be predicted, even in principle, from the behavior of the system's parts within simpler wholes then there also will be systemic properties which cannot be predicted, even in principle, on basis of the behavior of these parts. We show in an explicit case study drawn from molecular cell physiology that biochemical networks display this kind of emergence, even though they deploy only mechanistic explanations. This illustrates emergence and its place in nature. (shrink)

Belief in substance dualism, the idea that mind and matter are two different kinds of substances, has been found to be a strong predictor of belief in free will. Why? Here, we test whether believing that mind and matter are different kinds of substance correlates with differences in how people think of free will and/or differences in how people interpret the scenarios used to test their conceptions. We provided participants (N = 515) with two hypothetical scenarios where the world was (...) presented either as deterministic or not and asked them whether they thought that a given decision could be free in that world. Incompatibilist free will requires that determinism, the idea that at any instant only one possible future can follow from the state of the world, is false. Compatibilists hold that free will is possible even if determinism is true. In this study, we investigate if substance dualists are more compatibilist. We find that they are not, and that both dualists and physicalists agree that free will is incompatible with determinism. In addition, we show that dualists and physicalists are equally likely to commit bypassing, i.e., to misinterpret determinism as excluding mental causation. We also show that dualists have a stronger tendency to commit intrusion, i.e., to misinterpret determinism by importing indeterministic metaphysics into their interpretation of deterministic descriptions.

This study explores how distributing the controls of a video game among multiple players affects the sociality and engagement experienced in game play. A video game was developed in which the distribution of game controls among the players could be varied, thereby affecting the abilities of the individual players to control the game. An experiment was set up in which eight groups of three players were asked to play the video game while the distribution of the game controls was increased (...) in three steps. After each playing session, the players’ experiences of sociality and engagement were assessed using questionnaires. The results showed that distributing game control among the players increased the level of experienced sociality and reduced the level of experienced control. The game in which the controls were partly distributed led to the highest levels of experienced engagement, because the game allowed social play while still giving the players a sense of autonomy. The implications for interaction design are discussed. (shrink)

Internet users have access to a multitude of science-related information – on journalistic news sites but also on blogs with user-generated content. In this context, we investigated in two studies the factors which influence laypersons’ selective exposure. In an experiment with a collection of online news, parents were asked to search for information about the controversy surrounding violence in the media. Texts from high-reputation sources were clicked on more frequently – regardless of content –, whereas ratings by others had limited (...) effects. In a second experiment, the expertise and gender of blog authors as well as valence and number of ratings were varied. In this setting, texts from sources with positive ratings were read for longer. Results show that laypersons make use of credibility cues when deciding which articles to read. For online news sites, media reputation is most important, whereas in blogs, ratings are taken into account more frequently. (shrink)

The volume documents, and makes an original contribution to, an astonishing period in twentieth-century philosophy—the progress of Arne Naess's ecophilosophy from its inception to the present. It includes Naess's most crucial polemics with leading thinkers, drawn from sources as diverse as scholarly articles, correspondence, TV interviews and unpublished exchanges. The book testifies to the skeptical and self-correcting aspects of Naess's vision, which has deepened and broadened to include third world and feminist perspectives. Philosophical Dialogues is an essential addition to the (...) literature on environmental philosophy. (shrink)

Formalised knowledge systems, including universities and research institutes, are important for contemporary societies. They are, however, also arguably failing humanity when their impact is measured against the level of progress being made in stimulating the societal changes needed to address challenges like climate change. In this research we used a novel futures-oriented and participatory approach that asked what future envisioned knowledge systems might need to look like and how we might get there. Findings suggest that envisioned future systems will need (...) to be much more collaborative, open, diverse, egalitarian, and able to work with values and systemic issues. They will also need to go beyond producing knowledge about our world to generating wisdom about how to act within it. To get to envisioned systems we will need to rapidly scale methodological innovations, connect innovators, and creatively accelerate learning about working with intractable challenges. We will also need to create new funding schemes, a global knowledge commons, and challenge deeply held assumptions. To genuinely be a creative force in supporting longevity of human and non-human life on our planet, the shift in knowledge systems will probably need to be at the scale of the enlightenment and speed of the scientific and technological revolution accompanying the second World War. This will require bold and strategic action from governments, scientists, civic society and sustained transformational intent. (shrink)

Biological evolution provides a creative fount of complex and subtle adaptations, often surprising the scientists who discover them. However, because evolution is an algorithmic process that transcends the substrate in which it occurs, evolution’s creativity is not limited to nature. Indeed, many researchers in the field of digital evolution have observed their evolving algorithms and organisms subverting their intentions, exposing unrecognized bugs in their code, producing unexpected adaptations, or exhibiting outcomes uncannily convergent with ones in nature. Such stories routinely reveal (...) creativity by evolution in these digital worlds, but they rarely fit into the standard scientific narrative. Instead they are often treated as mere obstacles to be overcome, rather than results that warrant study in their own right. The stories themselves are traded among researchers through oral tradition, but that mode of information transmission is inefficient and prone to error and outright loss. Moreover, the fact that these stories tend to be shared only among practitioners means that many natural scientists do not realize how interesting and lifelike digital organisms are and how natural their evolution can be. To our knowledge, no collection of such anecdotes has been published before. This paper is the crowd-sourced product of researchers in the fields of artificial life and evolutionary computation who have provided first-hand accounts of such cases. It thus serves as a written, fact-checked collection of scientifically important and even entertaining stories. In doing so we also present here substantial evidence that the existence and importance of evolutionary surprises extends beyond the natural world, and may indeed be a universal property of all complex evolving systems.

The role of chance in historiography is a major question for the analysis of cultural transformations. Its main subject are the transformations of contingentia itself, which has undergone substantial changes in its mythical forms (as Tyche or Fortuna) as well in its historical expressions in philosophy, theology, politics, sciences, literature and art.

Often, the behavior of animals can be better explained and predicted, it seems, if we ascribe the capacity to have beliefs, intentions, and concepts to them. Whether we really can do so, however, is a debated issue. Particularly, Donald Davidson maintains that there is no basis in fact for ascribing propositional attitudes or concepts to animals. I will consider his and rival views, such as Colin Allen's three-part approach, for determining whether animals possess concepts. To avoid pure theoretical debate, however, (...) I will test these criteria using characteristic examples from ethology that depict a broad range of animal behavior. This will allow us to detect a series of gradations in animals' capacities, in the course of which we can think over what would count for or against an attribution of concepts and propositional attitudes to them in each single case. Self-conceit is our natural hereditary disease. Of all creatures man is the most wretched and fragile, and at once the most supercilious. ... It is by this conceit that man arrogates to himself ... divine properties, that he segregates himself from the mass of other creatures and raises himself above them .. (shrink)

Vacuolar ATPases (V‐ATPases, V1Vo‐ATPases) are rotary motor proton pumps that acidify intracellular compartments, and, when localized to the plasma membrane, the extracellular space. V‐ATPase is regulated by a unique process referred to as reversible disassembly, wherein V1‐ATPase disengages from Vo proton channel in response to diverse environmental signals. Whereas the disassembly step of this process is ATP dependent, the (re)assembly step is not, but requires the action of a heterotrimeric chaperone referred to as the RAVE complex. Recently, an alternative pathway (...) of holoenzyme disassembly was discovered that involves binding of Oxidation Resistance 1 (Oxr1p), a poorly characterized protein implicated in oxidative stress response. Unlike conventional reversible disassembly, which depends on enzyme activity, Oxr1p induced dissociation can occur in absence of ATP. Yeast Oxr1p belongs to the family of TLDc domain containing proteins that are conserved from yeast to mammals, and have been implicated in V‐ATPase function in a variety of tissues. This brief perspective summarizes what we know about the molecular mechanisms governing both reversible (ATP dependent) and Oxr1p driven (ATP independent) V‐ATPase dissociation into autoinhibited V1 and Vo subcomplexes.

We compare various notions of algorithmic randomness. First we consider relativized randomness. A set is n-random if it is Martin-Löf random relative to ∅. We show that a set is 2-random if and only if there is a constant c such that infinitely many initial segments x of the set are c-incompressible: C ≥ |x|-c. The ‘only if' direction was obtained independently by Joseph Miller. This characterization can be extended to the case of time-bounded C-complexity. Next we prove some results (...) on lowness. Among other things, we characterize the 2-random sets as those 1-random sets that are low for Chaitin's Ω. Also, 2-random sets form minimal pairs with 2-generic sets. The r.e. low for Ω sets coincide with the r.e. K-trivial ones. Finally we show that the notions of Martin-Löf randomness, recursive randomness, and Schnorr randomness can be separated in every high degree while the same notions coincide in every non-high degree. We make some remarks about hyperimmune-free and PA-complete degrees. (shrink)

This article presents the results of research conducted with secondary school teachers in Quebec, specifically in the Mauricie region. The authors propose a reflection on the construction of professional identity in a context of institutional crisis. They argue that in this context, the teacher can not rely on stable and social frameworks to build up a strong professional identity and that work experience that becomes the primordial material from which that identity is developed. Therefore, the teacher has to build its (...) identity from a set of rational narrative experience of professional practice.contrastée des attentes et des représentations d'étudiants en formation initiale à l'enseignement secondaire en fonction de leur engagement ou non dans un établissement scolaire Cet article présente les résultats d’une recherche menée auprès d’enseignants du niveau secondaire au Québec, plus spécifiquement dans la région de la Mauricie. Les auteurs proposent une réflexion sur la construction de l’identité professionnelle dans un contexte de crise des institutions. Ils soutiennent que dans ce contexte l’enseignant ne peut compter sur des cadres sociaux stables et solides pour se constituer une identité professionnelle et que c’est l’expérience au travail qui devient le matériau primordial à partir duquel s’élabore cette identité. Par conséquent, l’enseignant a à construire son identité à partir d’une mise en récit rationnelle de son expérience de la pratique professionnelle. (shrink)

A la manière des expériences perceptuelles qui nous présentent des formes, des couleurs, des sons, des textures, etc. les émotions nous présentent des propriétés évaluatives. Ainsi, les émotions constituent un type d’expérience perceptuelle spécifique, un type qui nous donne accès à des valeurs (plutôt qu’à des propriétés non axiologiques). Cette théorie d’origine meinongienne doit beaucoup Christine Tappolet qui y consacre un second livre Emotions, Values and Agency que tous les amoureux des choses vraiment bien faites ne pourront qu’apprécier. Cet article (...) est consacré à deux problèmes auxquels est confronté le partisan de la théorie perceptuelle des émotions, c’est-à-dire, de la théorie selon laquelle les émotions constituent un type spécifique d’expériences perceptuelles. Ce sont les problèmes de la justification et de la rationalité des émotions. Loin d’ignorer ces difficultés, Tappolet y consacre une partie de son premier chapitre (pages 31-45). Cette contribution a plus précisément deux objectifs. Le premier est de montrer pourquoi la justification ne pose pas un problème aussi sérieux que la rationalité à la théorie perceptuelle des émotions. Son second but est d’expliquer pourquoi je doute que la solution de Tappolet au problème de la rationalité fonctionne. (shrink)

La question des instincts est une voie d’entrée privilégiée pour le rapport du pragmatisme au naturalisme. Le problème que soulève la théorie des instincts de William James et John Dewey vient du maintien, à première vue surprenant, de l’idée d’une « nature humaine ». Je soutiens que c’est au sein même de la théorie pragmatiste des instincts que l’on trouve des arguments pour montrer que la nature humaine ne détermine pas univoquement la conduite. Bien comprendre la naturalité de l’être humain (...) suffit à défaire toute tentative pour l’ériger en source d’autorité des principes de la conduite. (shrink)

To date the problem of finding a general characterization of injective enumerability of recursively enumerable (r.e) classes of r.e. sets has proved intractable. This paper investigates the problem for r.e. classes of cofinite sets. We state a suitable criterion for r.e. classesC such that there is a boundn∈ω with |ω-A|≤n for allA∈C. On the other hand an example is constructed which shows that Lachlan's condition (F) does not imply injective enumerability for r.e. classes of cofinite sets. We also look at (...) a certain embeddability property and show that it is equivalent with injective enumerability for certain classes of cofinite sets. At the end we present a reformulation of property (F). (shrink)

Une relation étroite existe entre la détermination du nom, opérée en mettant en œuvre des procédés grammaticaux, et la référenciation, qui relève du domaine cognitif : en utilisant la langue pour désigner des éléments extralinguistiques, c’est-à-dire des entités concrètes ou abstraites du monde réel, il importe de s’assurer que ses interlocuteurs puissent appréhender la nature et l’identité des entités désignées. Nous fondant sur l’étude d’un corpus oral, nous proposons ici une perspective phonologique sur la détermination nominale, nous attardant essentiellement sur (...) divers phénomènes prosodiques situés à l’interface entre la structure informationnelle du discours et la construction de la référence au moyen de la détermination obtenue par des moyens grammaticaux. Certains phénomènes observés au niveau segmental nous conduisent en outre à relativiser le rôle des articles dans le processus de référenciation. (shrink)

Cette conclusion cherche à restituer la psychologie associationniste du xixe siècle dans son projet épistémologique au-delà de la diversité des positions de l’époque. On y défend l’idée que l’importance de l’association des idées fut de permettre de prétendre fonder la psychologie comme science empirique de l’esprit. C’est la nouvelle fonction de l’association, dégagée en réalité dès l’œuvre de Hume, qui a permis un tel projet : non plus simple transition habituelle d’une idée à une autre, mais principe génétique de l’ensemble (...) de la vie mentale.

Cet article vise à présenter le pluralisme de William James par contraste avec celui de Bertrand Russell. En effet, malgré les rapprochements qu’ont pu faire Jean Wahl et Gilles Deleuze, les pluralismes de Russell et de James sont profondément différents et par certains aspects incompatibles. Le pluralisme de Russell est d’origine logique et constitue un argument en faveur du réalisme en théorie de la connaissance. Le pluralisme de James est d’origine métaphysique et ne trouve sa signification et sa valeur que (...) dans les conséquences pratiques auxquelles il aboutit en morale. Le critère du premier est la reconnaissance d’une multiplicité d’éléments irréductibles les uns aux autres. Le critère du second est la reconnaissance de la liberté et de la nouveauté dans le monde. Le premier peut bien trouver son origine dans l’empirisme atomiste de Hume, mais le second est plutôt le prolongement des philosophies de Kant et de Renouvier. Le rapprochement malheureux entre les deux est dû selon nous a une équivoque sur la question des relations extérieures, qui empêche de comprendre correctement la pensée de James. (shrink)

A large body of work has demonstrated the utility of the Bayesian framework for capturing inference in both specialist and everyday contexts. However, the central tool of the framework, conditionalization via Bayes’ rule, does not apply directly to a common type of learning: the acquisition of conditional information. How should an agent change her beliefs on learning that “If A, then C”? This issue, which is central to both reasoning and argumentation, has recently prompted considerable research interest. In this paper, (...) we critique a prominent proposal and provide a new, alternative, answer. -/- . (shrink)

Ce chapitre discute de la justification des croyances testimoniales, c’est-à-dire de la justification des croyances que nous adoptons en nous appuyant sur le témoignage d’autrui. Plus précisément, la question à laquelle cette contribution s’intéresse est celle des conditions nécessaires et suffisantes de la justification des croyances testimoniales. Il y a deux manières classiques, et soi-disant antagonistes, d’y répondre: la réponse réductionnisme et la réponse non-réductionniste.

La première partie de ce chapitre est consacrée à distinguer les croyances testimoniales des croyances perceptuelles (section 1. et 1.1). Dans la seconde partie (section 2 à 2.3), nous présentons la réponse réductionniste et la réponse non-réductionniste ainsi que quelques-unes des objections les plus importantes adressées à chacune d’elles. La troisième partie explique pourquoi le prétendu antagonisme entre le réductionnisme et le non-réductionnisme n’en est pas un en exploitant ce que nous appelons « la thèse du malentendu » (3 à 3.2).

L’objectif de cet article est de clarifier les relations qu’entretiennent trois théories de la justification des croyances, toutes considérées comme des théories internalistes 1 : la conception déontique (le déontologisme), la conception accessibiliste (l’accessibilisme) et la conception mentaliste (le mentalisme). Nous expliquerons qu’en dépit de ce que l’on pourrait penser à première vue l’adoption de l’accessibilisme n’implique pas celle du mentalisme. Dans un second temps, nous montrerons pourquoi on ne peut être un défenseur de la conception déontique de la justification (...) sans être également un partisan de l’accessibilisme.2 L’intérêt de ces démonstrations réside principalement dans le fait qu’elles nous permettent de délier —ou, au contraire d’unir— le sort de ces différentes conceptions de la justification vis- à-vis des objections qui leur sont adressées. Faire la preuve de l’autonomie du mentalisme vis- à-vis de l’accessibilisme, par exemple, c’est établir l’immunité du premier vis-à-vis des objections que l’on peut faire au second. L’examen proprement dit des relations qui rattachent ces trois conceptions internalistes de la justification occupe les sections 4 et 5. Les sections 1, 2 et 3 sont des sections introductives. Elles sont, pour leur part, consacrées à la description de ces conceptions. (shrink)

Cette contribution a deux objectifs principaux. Le premier est de montrer que les intuitions sont caractérisées par ce que j’appellerai « une capacité rationnelle », c’est-à-dire, qu’elles sont susceptibles d’être évaluées quant à leur rationalité ou leur irrationalité. Le second objectif de cet article est d’étayer l’hypothèse selon laquelle les intuitions seraient des états affectifs proches des émotions — et non pas des états doxastiques ou des expériences perceptuelles —, en montrant qu’une telle conception affective des intuitions est seule capable (...) de rendre compte de la spécificité phénoménologique, la modularité, et la capacité rationnelle des intuitions. This article has two purposes. First, it wants to show that intuitions possess, what I shall call, “a rational capacity” : they are mental states susceptible to be assessed as rational or irrational. Second, this contribution aims at providing some evidence supporting the view that intuitions are affective states similar to emotions rather than doxastic or perceptual states. Such an affective account of the intuitions is the only one able to capture the specific phenomenology, the modularity and the rational capacity of the intuitions. (shrink)

Here P is the density operator of the system under consideration, and σ ± and σ 3 are the usual Pauli matrices, acting on atom i whose states are |1 > or |0 >, representing, respectively, the atom being in an excited state or in the ground state. B and C are appropriate decay constants and s has been called the pumping parameter [1]. It varies from s = 0 for pure damping to s = 1 for full laser action. (...) To solve the corresponding quantum master equations, three approaches have been taken: First, one focuses on the case of one atom. Second, one truncates eq. (1) and derives semi-classical models. Third, one employs numerical simulation methods such as the quantum trajectory method. While the latter method is very popular, it should be noted that the numerical complexity of the problem increases exponentially with the number of atoms, and so numerical methods soon become unfeasible.

Causal queries about singular cases, which inquire whether specific events were causally connected, are prevalent in daily life and important in professional disciplines such as the law, medicine, or engineering. Because causal links cannot be directly observed, singular causation judgments require an assessment of whether a co‐occurrence of two events c and e was causal or simply coincidental. How can this decision be made? Building on previous work by Cheng and Novick (2005) and Stephan and Waldmann (2018), we propose (...) a computational model that combines information about the causal strengths of the potential causes with information about their temporal relations to derive answers to singular causation queries. The relative causal strengths of the potential cause factors are relevant because weak causes are more likely to fail to generate effects than strong causes. But even a strong cause factor does not necessarily need to be causal in a singular case because it could have been preempted by an alternative cause. We here show how information about causal strength and about two different temporal parameters, the potential causes' onset times and their causal latencies, can be formalized and integrated into a computational account of singular causation. Four experiments are presented in which we tested the validity of the model. The results showed that people integrate the different types of information as predicted by the new model. (shrink)

La théorie de la perception emprunte, chez Descartes, deux chemins différents. D’un côté, la perception interne se développe selon le paradigme visuel de l’intuitus ; de l’autre, la perception externe est pensée à l’aune d’un modèle discursif. À la présentation s’opposerait donc une signification. Or, contre les commentateurs qui ont fait de Descartes le philosophe ayant ouvert l’ère de la représentation, l’auteur montre que le modèle discursif prime sur le paradigme visuel et que bien que Descartes affirme que les idées (...) sont comme des images et des tableaux, son modèle de la perception est en fait celui de la fable, c’est-à-dire d’un texte.

Pour la phénoménologie de Jean-Luc Marion, Descartes est le philosophe ayant achevé la métaphysique. Mais il faut entendre toute la polyphonie de ce terme. D’un côté, il l’a achevée au sens où il l’a parachevée, la portant à son sommet en fixant ses concepts et ses enjeux pour la modernité à venir. De l’autre, il l’a achevée en montrant ses brisures, la rendant caduque par la mise au jour de son dépassement possible selon deux concepts qui déterminent aussi deux moments (...) cartésiens : l’infini puis la chair. Cette ambivalence eu égard à la métaphysique (fixation puis dépassement), résonne dans la phénoménologie de la donation puisqu’elle détermine la mise en place de la distinction entre les phénomènes saturés et les phénomènes de droit commun. Ainsi, Descartes est utilisé comme le philosophe qui fixe les frontières, non seulement entre philosophie et métaphysique, mais aussi celles qui passent au cœur même de la phénoménologie. Pourtant, à de nombreuses reprises, Marion montre que cette fixation des frontières n’est pas aussi aisée à opérer qu’il n’y paraît, et qu’il y a un brouillage essentiel et originaire de celles-là. Pour la phénoménologie de la donation, Descartes est donc à la fois un repoussoir et un aimant, ce qu’il faut dépasser et ce à partir de quoi on le dépasse, ce qui disparaît dans la mort de la métaphysique, mais aussi ce qui s’attarde dans ce qui lui survit.
