Temporal regularities in speech, such as interdependencies in the timing of speech events, are thought to scaffold early acquisition of the building blocks in speech. By providing on-line clues to the location and duration of upcoming syllables, temporal structure may aid segmentation and clustering of continuous speech into separable units. This hypothesis tacitly assumes that learners exploit predictability in the temporal structure of speech. Existing measures of speech timing tend to focus on first-order regularities among adjacent units, and are overly (...) sensitive to idiosyncrasies in the data they describe. Here, we compare several statistical methods on a sample of 18 languages, testing whether syllable occurrence is predictable over time. Rather than looking for differences between languages, we aim to find across languages (using clearly defined acoustic, rather than orthographic, measures), temporal predictability in the speech signal which could be exploited by a language learner. First, we analyse distributional regularities using two novel techniques: a Bayesian ideal learner analysis, and a simple distributional measure. Second, we model higher-order temporal structure—regularities arising in an ordered series of syllable timings—testing the hypothesis that non-adjacent temporal structures may explain the gap between subjectively-perceived temporal regularities, and the absence of universally-accepted lower-order objective measures. Together, our analyses provide limited evidence for predictability at different time scales, though higher-order predictability is difficult to reliably infer. We conclude that temporal predictability in speech may well arise from a combination of individually weak perceptual cues at multiple structural levels, but is challenging to pinpoint. (shrink)

In recent years, the genetic testing and selection of IVF embryos, known as preimplantation genetic testing (PGT), has gained much traction in clinical assisted reproduction for preventing transmission of genetic defects. However, a more recent ethically and morally controversial development in PGT is its possible use in selecting IVF embryos for optimal intelligence quotient (IQ) and other non–disease-related socially desirable traits, such as tallness, fair complexion, athletic ability, and eye and hair colour, based on polygenic risk scores (PRS), in what (...) is referred to as PGT-P. Artificial intelligence (AI) and machine learning–based analysis of big data sets collated from genome sequencing of specific human ethnic populations can be used to estimate an individual embryo’s likelihood of developing such multifactorial traits by analysing the combination of specific genetic variants within its genome. Superficially, this technique appears compliant with Islamic principles and ethics. Because there is no modification of the human genome, there is no tampering with Allah’s creation (taghyīr khalq Allah). Nevertheless, a more critical analysis based on the five maxims of Islamic jurisprudence (qawa'id fiqhiyyah) that are often utilized in discourses on Islamic bioethics, namely qaṣd (intention), yaqın̄ (certainty), ḍarar (injury), ḍarūra (necessity), and `urf (custom), would instead reveal some major ethical and moral flaws of this new medical technology in the selection of non–disease-related socially desirable traits, and its non-compliance with the spirit and essence of Islamic law (shariah). Muslim scholars, jurists, doctors, and biomedical scientists should debate this further and issue a fatwa on this new medical technology platform. (shrink)

This book contains an introduction to symbolic logic and a thorough discussion of mechanical theorem proving and its applications. The book consists of three major parts. Chapters 2 and 3 constitute an introduction to symbolic logic. Chapters 4–9 introduce several techniques in mechanical theorem proving, and Chapters 10 an 11 show how theorem proving can be applied to various areas such as question answering, problem solving, program analysis, and program synthesis.

Generalising what is learned about one stimulus to other but perceptually related stimuli is a basic behavioural phenomenon. We evaluated whether a rule learning mechanism may serve to explain such generalisation. To this end, we assessed whether inference rules communicated through verbal instructions affect generalisation. Expectancy ratings, but not valence ratings, proved sensitive to this manipulation. In addition to revealing a role for inference rules in generalisation, our study has clinical implications as well. More specifically, we argue that targeting inference (...) rules might prove to be an effective strategy to affect the excessive generalisation that is often observed in psychopathology. (shrink)

This research uses a normative approach to examine the relationship between basic income and migration. The decisive variable is the effect of labour automation, which increases economic insecurities globally, leaving some nation states in a position to cope with this and others not. The insecurities will increase migratory pressures on one hand but also justify the introduction of basic income on a nation state level on the other. The normative guideline is the republican conception of freedom as non-domination. This is (...) used to justify a basic income, analyse how labour automation creates dominating structures and how borders dominate migrants seeking to move to countries which introduce a basic income. The result is that nation states that introduce a basic income to counter internal domination through labour automation, also have to look outside of their nation state. The imposition of borders in order to keep a basic income sustainable as well as labour automation itself, establish a form of domination over less developed countries and thus demand international regulation.

In epistemology and philosophy of science, there has been substantial debate about truth’s relation to understanding. “Non-factivists” hold that radical departures from the truth are not always barriers to understanding; “quasi-factivists” demur. The most discussed example concerns scientists’ use of idealizations in certain derivations of the ideal gas law from statistical mechanics. Yet, these discussions have suffered from confusions about the relevant science, as well as conceptual confusions. Addressing this example, we shall argue that the ideal gas law is best (...) interpreted as favoring non-factivism about understanding, but only after delving a bit deeper into the statistical mechanics that has informed these arguments and stating more precisely what non-factivism entails. Along the way, we indicate where earlier discussions have gone astray, and highlight how a naturalistic approach furnishes more nuanced normative theses about the interaction of rationality, understanding, and epistemic value.

Dans ce pays où, à la façon du Dictionnaire des idées reçues, il convient de tonner contre les méfaits de l’État jacobin, nul ne s’avise de savoir au juste comment celui-ci fonctionne ni ce qu’il fait. J’adopte en quelque sorte la position en miroir de l’idée reçue : je ne suis pas sûr de savoir ce qu’il faut penser de l’État en général, mais je sais empiriquement et en détails ce qu’il fait et comment il fonctionne. Je ne déduis pas (...) de proposition de réforme d’une théorie de l’État mais je tire de mon expérience l’idée d’une nouvelle façon d’agir ; je ne dessine pas la cité idéale mais je cherche ce qui pourrait faire revenir l’action dans l’institution.

In 2012, the international PISA survey reinforced the observation that the French educational system is one of the most unequal among OECD countries. The observation of serious inequalities in access to educational success for pupils from disadvantaged backgrounds could lead to a pessimistic vision suggesting that any possibility of transformation of the system is doomed to failure. Thus, the fight against inequalities in access to educational success is a form of runaway object which constitutes a challenge for research which treats (...) the social context as evolving and susceptible to significant and novel transformations. Developmental work research aims to support the work of professionals in the re-elaboration of their practices by seeking to go beyond the status quo of an unequal school. Drawing on this framework within an institutional network of schools, we seek to show how the intervention has highlighted power issues inscribed in the structures and how the actors, through their commitment in the research collaborative process, seek to go beyond the power issues inscribed in their work routines and enacted during the research process by different kinds of antagonism. We will argue that the fight against educational inequality involves overcoming systemic power relations crystallized in institution. This systemic power is expressed by a form of episodic power. Our results show restrictive and constructive effect on the expansive learning process and on the construction of a collective in the formative interventions. The restrictive side of epistemic power should be linked to systemic power which is historically inherited. We discuss the results in the light of the emergence of a fourth generation of activity theory. Our research makes it possible to make conceptual and methodological progress in the construction of a fourth generation of activity theory by showing the need for analysis and expansively learn about problematic power relations in heterogeneous collectives.

Cadherins are a multigene family of proteins which mediate homophilic calcium‐dependent cell adhesion and are thought to play an important role in morphogenesis by mediating specific intercellular adhesion. Different lines of experimental evidence have recently indicated that the site responsible for mediating adhesive interactions is localized to the first extracellular domain of cadherin. Based upon an analysis of the sequence of this domain, I show that cadherins can be classified into three groups with distinct structural features. Furthermore, using this sequence (...) information a phylogenetic tree relating the known cadherins was assembled. This is the first such tree to be published for the cadherins. One cadherin subtype, neural cadherin (N‐cadherin), shows very little sequence divergence between species, whereas all other cadherin subtypes show more substantial divergence, suggesting that selective pressure upon this domain may be greater for N‐cadherin than for other cadherins. Phylogenetic analysis also suggests that the gene duplications which established the main branches leading to the different cadherin subtypes occurred very early in their history. These duplications set the stage for the diversified superfamily we now observe. (shrink)

To a large extent and one that is highly structuring, energy choices that are made in a society are political choices. This article aims at studying how these choices can be redirected by technological developments associated with renewable energy, thus contributing to a redistribution of opportunities and correspondingly to social reorganizations. In order to show that the development of alternative energies not only depends on technological advances but can also, in the process, reveal political potentialities, three steps are proposed. The (...) first step will clarify the theoretical arguments in favor of an approach in terms of “technological potentialism.” Second, we will extend this approach by identifying a set of potentialities linked with renewable energies and the model that could arise from these alternative forms or approaches. Finally, we will examine how these potentialities could find paths to become effective. (shrink)

Alors que le temps présent paraît marqué par une incertitude forte, voire croissante, comment trouver des prises sur ce qui est en devenir et qui pourrait composer le futur? Cette contribution propose de montrer que la science-fiction offre un matériau qui a aussi une pertinence et qui peut être travaillé pour être incorporé dans un processus de production de connaissance. Les textes de science-fiction peuvent en effet être pris à la fois comme un réservoir d’expériences de pensée et comme des (...) formes de problématisations. En s’appuyant sur un corpus de textes francophones et anglophones orientés vers un futur plus ou moins proche et généralement considérés comme porteurs de positions engagées, une première base de démonstration précisera d’abord l’appréhension réflexive qui peut être faite de la science-fiction au-delà de la forme culturelle et de son expression littéraire. Une seconde avancera ensuite une série de propositions méthodologiques pour saisir l’objet et pouvoir traduire cet imaginaire en prises expérimentales sur le futur. (shrink)

Optical distortions as a visual disturbance are inherent in many optical devices such as spectacles or virtual reality headsets. In such devices, distortions vary spatially across the visual field. In progressive addition lenses, for example, the left and right regions of the lens skew the peripheral parts of the wearers visual field in opposing directions. The human visual system adapts to homogeneous distortions and the respective aftereffects are transferred to non-retinotopic locations. This study investigates simultaneous adaptation to two opposing distortions (...) at different retinotopic locations. Two oppositely skewed natural image sequences were presented to 10 subjects as adaptation stimuli at two distinct locations in the visual field. To do so, subjects were instructed to keep fixation on a target. Eye tracking was used for gaze control. Change of perceived motion direction was measured in a direction identification task. The point of subjective equality, that is, the angle at which a group of coherently moving dots was perceived as moving horizontal, was determined for both retinal locations. The shift of perceived motion direction was evaluated by comparing PSE before and after adaptation. A significant shift at both retinal locations in the direction of the skew distortion of the corresponding adaptation stimulus is demonstrated. Consequently, parallel adaptation to two opposing distortions in a retinotopic reference frame was confirmed by this study. (shrink)

Introduction of O2 to Earth's early biosphere stimulated remarkable evolutionary adaptations, and a wide range of electron acceptors allowed diverse, energy-yielding metabolic pathways. Enzymatic reduction of O2 yielded a several-fold increase in energy production, enabling evolution of multi-cellular animal life. However, utilization of O2 also presented major challenges as O2 and many of its derived reactive oxygen species are highly toxic, possibly impeding multicellular evolution after the Great Oxidation Event. Remarkably, ROS, and especially hydrogen peroxide, seem to play a major (...) part in early diversification and further development of cellular respiration and other oxygenic pathways, thus becoming an intricate part of evolution of complex life. Hence, although harnessing of chemical and thermo-dynamic properties of O2 for aerobic metabolism is generally considered to be an evolutionary milestone, the ability to use ROS for cell signaling and regulation may have been the first true breakthrough in development of complex life. The importance of Earth's oxygen cycle and reactive oxygen species produced on the evolution of complex life. The ability to detoxify oxygen species is not a trait that emerged as a response to increased O2 levels but rather crucial adaptation to the early Earth's weakly oxic microenvironments. (shrink)

In 1984, Edward O. Wilson proposed the idea that natural selection has resulted in an adaptive love of life-forms and life-like processes ('biophilia') in humans. To date, the idea of biophilia has been viewed as an ultimate explanation of many conservation attitudes in humans. In this paper, we contend that environmental ethics has little to gain from the biophilia hypothesis. First, the notion is open to various and even conflicting interpretations. Second, the empirical findings that do seem to corroborate a (...) more well-defined version of the biophilia hypothesis can often be accounted for by alternative hypotheses. Third, the evolutionary reasoning behind the biophilia hypothesis tends to be unclear, and sometimes even inaccurate. (shrink)

Standard dual-process models in the action domain postulate that stimulus-driven processes are responsible for suboptimal behavior because they take them to be rigid and automatic and therefore the default. We propose an alternative dual-process model in which goal-directed processes are the default instead. We then transfer the dual- process logic from the action domain to the emotion domain. This reveals that emotional behavior is often attributed to stimulus-driven processes. Our alternative model submits that goal-directed processes could be the primary determinant (...) of emotional behavior instead. We evaluate the type of empirical evidence required for validating our model and we consider implications of our model for behavior change, encouraging strategies focused on the expectancies and values of action outcomes.

L’engagement évangélique à Singapour transforme le rapport pratique à la politique et les modalités de l’action missionnaire. Sans renoncer à certains combats – notamment autour des « valeurs familiales » – l’évangélisme local a dû se plier à une régulation étatique contraignante. Ses dirigeants ont eux-mêmes intériorisé l’idéologie officielle de « l’harmonie religieuse » comme une des composantes d’un ordre social conservateur, incarné depuis l’indépendance par le gouvernement du People’s Action Party. Cette affinité idéologique a néanmoins buté à partir de (...) 2007 sur une pierre d’achoppement : le débat sur la dépénalisation de l’homosexualité qui s’est conclu en 2022 par l’abrogation de la section 377A du code pénal sanctionnant l’homosexualité masculine.

Due to restrictions against the COVID-19 pandemic, spectators were not allowed to attend soccer matches at the end of the 2019/2020 season. Previous studies suggest that the absence of a home crowd changes the home field advantage in terms of match outcomes, offensive performance, and referee decisions. However, because of the small sample sizes, these changes may be random rather than meaningful. To test this, we created 1,000,000 randomized samples from the previous four seasons with the exact same number of (...) matches played behind closed doors in Europe’s four most elite soccer leagues at the end of the 2019/2020 season. We found that across countries, performance indices and referee decisions indeed changed to the detriment of the home team beyond the level of chance. However, this overall pattern could be ascribed to specific countries. Most importantly, the proportion of points won by the home teams declined significantly only in Germany, which was accompanied by a meaningful increase in the proportion of goals scored by the away teams and the proportion of yellow cards given to the home teams. We conclude that the home field advantage may indeed be lost when spectators are absent. However, in future studies, more detailed behavioral analyses are needed to determine the robustness and the behavioral determinants of this phenomenon across leagues and countries. (shrink)

We describe reversible adaptive trees, a class of stochastic algorithms modified from the formerly described adaptive trees. They evolve in time a finite subset of an ambient Euclidean space of any dimension, starting from a seed point and, accreting points to the evolving set, they grow branches towards a target set which can depend on time. In contrast with plain adaptive trees, which were formerly proven to have strong convergence properties to a static target, the points of reversible adaptive trees (...) are removed from the tree when they have not been used recently enough in a path from the root to an accreted point. This, together with a straightening process performed on the branches, permits the tree to follow some moving targets and still remain adapted to it. We then discuss in what way one can see such reversible trees as a model for a qualitative property of resilience, which leads us to discuss qualitative modeling. (shrink)

Résumé En prologue de cet article, nous rappelons les circonstances qui ont amené Jochen Hoock à contribuer à une nouvelle Histoire de Rouen. Il vise aussi à caractériser la spécificité de son approche par rapport à celle développée par Jean-Pierre Bardet dans la précédente Histoire de Rouen. Puis est envisagé, en deux temps, l’apport principal de l’auteur. Durant la première moitié du XVIIe siècle Rouen apparaît comme une grande ville marchande sous tension du fait notamment des guerres européennes. Les années (...) 1650-1700 sont marquées par des difficultés économiques liées à l’exacerbation des tensions religieuses avant que le commerce colonial et international serve d’appui à l’expansion industrielle des années 1680-1740. En conclusion, la démarche de Jochen Hoock paraît essentielle en ce qui concerne l’articulation entre commerce et industrie et aussi entre différents niveaux d’analyse, du local à l’international et au global.

The universal allowance became, in Belgium, the sole theme of the electoral campaign of a political party. During the general elections 0f13 June 1999, Vivant, until that point a small unknown party, united around its programme, 2% of the vote. Founded in 1997 by the businessman and member of the Basic Income European Network Roland Duchâtelet, V I VA NT participated nevertheless for the first time in the electoral game. Through an enormous campaign, financed entirely by Duchâtelet, this party without (...) an elected representative, succeeded in making its key concerns the focal point of public attention. With the slogan ’free yourself by giving yourself a basic income", VIVANT brought the universal allowance into public debate in the Low Countries. (shrink)
