La présence d'animaux au sein des structures d'accueil et ses apports pédagogiques

Cette recherche porte sur les apports bénéfiques de l’animal sur le développement des enfants âgés de 6 à 12 ans, au point de vue cognitif, affectif, social et moteur. Elle se s’intéresse également sur le lien qu’entretiennent l’enfant et l’animal afin de mieux le comprendre. Un parallèle avec la zoothérapie qui utilise ce contact à des fins thérapeutiques, semblait nécessaire. Cette recherche a été menée, tout d’abord, de manière bibliographique, puis sur le terrain afin de comprendre les divers enjeux d’une telle pratique. Grâce aux entretiens, un apport pratique ainsi que les points de vue de professionnels de différents domaines en contact avec l’animal ont pu être extraits. En conclusion, l’animal peut être un excellent outil dans les métiers en lien avec les enfants pour développer des apprentissages, en complément des diverses ressources déjà existantes, mais à condition que l’introduction de l’animal soit réfléchie et étudiée

Uncertainty-dependent Effects of Monetary Policy Shocks: A New Keynesian Interpretation

We estimate a nonlinear VAR model to study the real effects of monetary policy shocks in regimes characterized by high vs. low macroeconomic uncertainty. We find unexpected monetary policy moves to exert a substantially milder impact in presence of high un- certainty. We then exploit the set of impulse responses coming from the nonlinear VAR framework to estimate a medium-scale new-Keynesian DSGE model with a minimum- distance approach. The DSGE model is shown to be able to replicate the VAR evidence in both regimes thanks to different estimates of some crucial structural parameters. In particular, we identify a steeper new-Keynesian Phillips curve as the key factor behind the DSGE model\u2019s ability to replicate the milder macroeconomic responses to a monetary pol- icy shock estimated with our VAR in presence of high uncertainty. A version of the model featuring firm-specific capital is shown to be associated to estimates of the price frequency which are in line with some recent evidence based on micro data

An unusual case of loss of consciousness: when an epileptic brain let the heart slow down

The differential diagnosis of an episode of transient loss of consciousness can be sometimes very tricking, in particular when symptoms peculiar of syncope are mixed with focal neurological symptoms. We report the case of a 54-year-old woman who suddenly claimed, during a polygraphic recording (electroencephalography/electrocardiogram), a feeling of fear and tachycardia followed by loss of consciousness and then a tonic posturing of the left limbs. Polygraphic recording showed a critical electroencephalographic pattern starting from left temporo-zygomatic channels followed after few seconds by a sudden slowing of cortical background activity associated with an episode of asystole, as witnessed simultaneously by electrocardiogram. Muscular activity covered electroencephalographic activity of following minutes. This case provides an opportunity to highlight the existence of rare conditions such as ictal arrhythmias which should be considered in the differential diagnosis of episodes of transient loss of consciousness in particular when dysautonomic and neurological symptoms are intermingled. Autonomic symptoms (vomiting, tachycardia, cyanosis, bradycardia and asystole) may be also more frequent in idiopathic (more rarely symptomatic) epilepsies of childhood (Panayiotopoulos syndrome)

A model of the Fed’s view on inflation

view often expressed by the Fed is that three components matter in inflation dynamics: a trend anchored by long run inflation expectations; a cycle connecting nominal and real variables; and oil prices. This paper proposes an econometric structural model of inflation formalising this view. Our findings point to a stable expectational trend, a sizeable and well identified Phillips curve and an oil cycle which, contrary to the standard rational expectation model, affects inflation via expectations without being reflected in the output gap. The latter often overpowers the Phillips curve. In fact, the joint dynamics of the Phillips curve cycle and the oil cycles explain the inflation puzzles of the last ten years

Totally Geodesic and Parallel Hypersurfaces of Siklos Spacetimes

We classify and describe totally geodesic and parallel hypersurfaces for the entire class of Siklos spacetimes. A large class of minimal hypersurfaces is also described.Comment: 22 page

A model of the Fed’s view on inflation

We develop a medium-size semi-structural time series model of inflation dynamics that is consistent with the view – often expressed by central banks – that three components are important: a trend anchored by long-run expectations, a Phillips curve and temporary fluctuations in energy prices. We find that a stable long-term inflation trend and a well identified steep Phillips curve are consistent with the data, but they imply potential output declining since the new millennium and energy prices affecting headline inflation not only via the Phillips curve but also via an independent expectational channel

From rubber hands to neuroprosthetics: Neural correlates of embodiment

© 2023 The Authors. Published by Elsevier Ltd. This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/)Our interaction with the world rests on the knowledge that we are a body in space and time, which can interact with the environment. This awareness is usually referred to as sense of embodiment. For the good part of the past 30 years, the rubber hand illusion (RHI) has been a prime tool to study embodiment in healthy and people with a variety of clinical conditions. In this paper, we provide a critical overview of this research with a focus on the RHI paradigm as a tool to study prothesis embodiment in individuals with amputation. The RHI relies on well-documented multisensory integration mechanisms based on sensory precision, where parietal areas are involved in resolving the visuo-tactile conflict, and premotor areas in updating the conscious bodily representation. This mechanism may be transferable to prosthesis ownership in amputees. We discuss how these results might transfer to technological development of sensorised prostheses, which in turn might progress the acceptability by users.Peer reviewe

Helix surfaces for Berger-like metrics on the anti-de Sitter space

We consider the Anti-de Sitter space $\mathbb{H}^3_1$ equipped with Berger-like metrics, that deform the standard metric of $\mathbb{H}^3_1$ in the direction of the hyperbolic Hopf vector field. Helix surfaces are the ones forming a constant angle with such vector field. After proving that these surfaces have (any) constant Gaussian curvature, we achieve their explicit local description in terms of a one-parameter family of isometries of the space and some suitable curves. These curves turn out to be general helices, which meet at a constant angle the fibers of the hyperbolic Hopf fibration
