description: The Fisher Information Matrix formalism is extended to cases where the data is divided into two parts (X,Y), where the expectation value of Y depends on X according to some theoretical model, and X and Y both have errors with arbitrary covariance. In the simplest case, (X,Y) represent data pairs of abscissa and ordinate, in which case the analysis deals with the case of data pairs with errors in both coordinates, but X can be any measured quantities on which Y depends. The analysis applies for arbitrary covariance, provided all errors are gaussian, and provided the errors in X are small, both in comparison with the scale over which the expected signal Y changes, and with the width of the prior distribution. This generalises the Fisher Matrix approach, which normally only considers errors in the `ordinate' Y. In this work, we include errors in X by marginalising over latent variables, effectively employing a Bayesian hierarchical model, and deriving the Fisher Matrix for this more general case. The methods here also extend to likelihood surfaces which are not gaussian in the parameter space, and so techniques such as DALI (Derivative Approximation for Likelihoods) can be generalised straightforwardly to include arbitrary gaussian data error covariances. For simple mock data and theoretical models, we compare to Markov Chain Monte Carlo experiments, illustrating the method with cosmological supernova data. We also include the new method in the Fisher4Cast software.

description: In the simplest models of asymmetric dark matter (ADM) annihilation signals are not expected, since the DM is non-self-conjugate and the relic density of anti-DM is negligible. We investigate a new class of models in which a symmetric DM component, in the `low-mass' 1-10 GeV regime favoured for linking the DM and baryon asymmetries, is repopulated through decays. We find that, in models without significant velocity dependence of the annihilation cross section, observational constraints generally force these decays to be (cosmologically) slow. These late decays can give rise to gamma-ray signal morphologies differing from usual annihilation profiles. A distinctive feature of such models is that signals may be absent from dwarf spheroidal galaxies.

migration scenarios

description: This report is a part of deliverable “D.6.2. Report on migration and demographic patterns in the EU CEE countries and potential source countries” from the project FUME – Future Migration Scenarios for Europe (870649), financed with the Horizon 2020 programme. In particular, this country report focuses on critical analysis of migration data from Slovenia, and in particular - immigration data. The analysis consists of an overview of stock and flow data on migrants including such dimensions as age groups, gender, country of origin, types of permits and length of residence. This report is a first step in analytical task which aims to determine migration potential from and to Slovenia and furthermore, to provide necessary data input for fine-tuning of FUME migration projection model.
 Slovenia is a post-communist country with a long history of emigration and a relatively new waves of immigration from both within and outside of Europe. Prior to the declaration of independence from Yugoslavia in 1991, the country’s migration trends resembled to a large extent those of other Southern and South-European states. Mainly economically-driven, but also in many periods also politically, Slovene emigrants used to leave their ethnic lands since the mid-nineteenth century and settled abroad - mostly in Western Europe but also overseas, in North and South America, Australia and many other countries. In 1980s, when Slovenia was already also an immigrant country, emigration trends slowed down until 2004, when the accession to the European Union open new pathways and opportunities for potential migrants. Contemporary Slovenia is among the few countries in the region with an increase in population when compared to the period when the communist era ended in Europe. That demographic increase, observed especially after 2017, is largely attributed to immigrants who come to Slovenia mostly for work, but also for family reasons and education. Most of immigrants come from the countries of former Yugoslavia.
 This report presents the historical framework of migration transformation in Slovenia, diaspora dynamics and major national groups of immigrants and their demographic structure. It also provides critical analysis of the validity of the main statistical data sources, and suggests migration scenarios for the future.

description: Ce mémoire de Master porte le sentiment d’auto-efficacité des enseignant·e·s (SAE) et l’accompagnement d’un·e élève endeuillé·e. Il s’agit de questionner les enseignant·e·s sur leur propre sentiment de capacité à effectuer différentes tâches liées à ces situations particulières, ainsi que d’identifier les facteurs qui peuvent expliquer ce SAE. Notre méthodologie quantitative se base sur un questionnaire en deux parties. La première partie interroge des enseignant·e·s primaires en Suisse sur différents facteurs : leur expérience professionnelle, la formation, le vécu personnel et leur rapport à la mort. La deuxième partie constitue notre échelle d’évaluation du SAE, créée sur la base de notre cadre théorique. À l’issue de nos résultats, nous constatons que plus les enseignant·e·s gagnent en années d’expérience, plus ils/elles ont un SAE élevé. Par ailleurs, celles et ceux qui ont déjà accompagné un·e élève endeuillé·e se sentiraient également davantage capables si cette situation se présentait à nouveau dans le futur. Les enseignant·e·s ayant suivi une formation auraient également tendance à avoir un SAE plus élevé. Aussi, le rapport à la mort semble lié au SAE : les enseignant·e·s avec un rapport serein auraient davantage confiance en leur capacité à accompagner un enfant endeuillé·e que les personnes avec un rapport difficile. En outre, nous ne constatons pas de lien entre le vécu personnel d’un deuil durant l’enfance et l’adolescence.

description: We study the effect of the fast rotation and vertical viscosity on the lifespan of solutions to the three-dimensional primitive equations (also known as the hydrostatic Navier-Stokes equations) with impermeable and stress-free boundary conditions. Firstly, for a short time interval, independent of the rate of rotation | Ω | , we establish the local well-posedness of solutions with initial data that is analytic in the horizontal variables and only L 2 in the vertical variable. Moreover, it is shown that the solutions immediately become analytic in all the variables with increasing-in-time (at least linearly) radius of analyticity in the vertical variable for as long as the solutions exist. On the other hand, the radius of analyticity in the horizontal variables might decrease with time, but as long as it remains positive the solution exists. Secondly, with fast rotation, i.e., large | Ω | , we show that the existence time of the solution can be prolonged, with "well-prepared" initial data. Finally, in the case of two spatial dimensions with Ω = 0 , we establish the global well-posedness provided that the initial data is small enough. The smallness condition on the initial data depends on the vertical viscosity and the initial radius of analyticity in the horizontal variables.

description: We provide evidence for conjectural dualities between nonrelativistic Chern-Simons-matter theories and theories of (fractional, nonAbelian) quantum Hall fluids in $2+1$ dimensions. At low temperatures, the dynamics of nonrelativistic Chern-Simons-matter theories can be described in terms of a nonrelativistic quantum mechanics of vortices. At critical coupling, this may be solved by geometric quantisation of the vortex moduli space. Using localisation techniques, we compute the Euler characteristic ${\chi}(\mathcal{L}^\lambda)$ of an arbitrary power $\lambda$ of a quantum line bundle $\mathcal{L}$ on the moduli space of vortices in $U(N_c)$ gauge theory with $N_f$ fundamental scalar flavours on an arbitrary closed Riemann surface. We conjecture that this is equal to the dimension of the Hilbert space of vortex states when the area of the metric on the spatial surface is sufficiently large. We find that the vortices in theories with $N_c = N_f = \lambda$ behave as fermions in the lowest nonAbelian Landau level, with strikingly simple quantum degeneracy. More generally, we find evidence that the quantum vortices may be regarded as composite objects, made of dual anyons. We comment on potential links between the dualities and three-dimensional mirror symmetry. We also compute the expected degeneracy of local Abelian vortices on the $\Omega$-deformed sphere, finding it to be a $q$-analog of the undeformed case.

description: Abstract
Andri Ananta Yudhishthira. 2023. Dissertation of Doctor of Law Program, Diponegoro University Semarang.  Reformulation of Legal Policies in Increasing Local Revenues. The purpose of this study is to analyze; 1) How is the effectiveness of the formulation of legal policies to increase the original income of the current area? ; 2) How will the policy reformulation be to increase local income in the future?. The research method used is empirical juridical with a statutory approach, a concept approach, and a case study. The results showed that; 1) The effectiveness of the legal policy formulation to increase the current local indigenous income in Development in Jambi Province can be said to be quite good. This can be seen from the well-maintained inflation, GRDP that has returned to growth, the Gini Ratio which is getting closer to the target, and the Farmer Exchange Rate is getting better, the interest rate is still set low, the poverty rate is still quite high even though it has fallen from last year. In addition, the level of inequality must also be corrected even though it has dropped from last year. The challenges of regional economic development in Jambi Province are as follows; a) The impact of the Covid-19 Pandemic is still being felt; The economy of Jambi Province is still facing several challenges, especially for recovery from the COVID-19 pandemic; b) Infrastructure support needs to be improved; The problems faced by Jambi Province are related to the limited basic service infrastructure and the economy; c) Challenges of Environmentally Damaging Activities; activities that result in environmental damage, such as encroachment of forest areas, burning of forests and land for the benefit of agricultural cultivation and illegal mining activities d) Social Challenges of Population; the number of residents domiciled is different from the KK / KTP owned by 10.18% or around 361.37 thousand inhabitants e) Regional Geographical Challenges; The location of Jambi is geographically very strategic in the ASEAN and Interregional Regions of Sumatra which has not been supported by adequate infrastructure.  3) Reformulation of policies to increase local income in the future including; a) Increase in Gross Domestic Product, b) Control of Interest Rates, Inflation, Exchange Rate, c) Infrastructure Improvement, d) Employment Development and Reduction of Unemployment, e) Improvement of leading and potential sectors in the regions. The government should be more serious about developing leading and potential sectors in the regions. The leading sectors are the Agriculture, Forestry & Fisheries sector, the Mining & Quarrying Sector and the Education Services Sector. Meanwhile, the Water Procurement Business Sector, Waste Management, Waste and Recycling as well as the Information and Communication Sector are potential sectors to be developed in Jambi Province.

description: The first search for the rare radiative decay $\Xi_b^- \to \Xi^- \gamma$ is performed using data collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.4 fb$^{-1}$. The $\Xi_b- \to \Xi^- J/\psi$ channel is used as normalization. No $\Xi_b^- \to \Xi^- \gamma$ signal is found and an upper limit of $\mathcal{B}(\Xi_b^- \to \Xi^- \gamma) < 1.3 \times 10^{-4}$ at 95% confidence level is obtained.

description: Цель: изучить подверженность женщин репродуктивного возраста формированию избыточной массы тела и ожирению, а также причин, способствующих возникновению этих состояний. Материалы и методы исследования. При помощи опросника WHQ провели анкетирование среди женщин г. Баку. В анкеты был включен блок вопросов, отражающий состояние подверженности женщин избыточной массе тела и ожирению и способствующие им причины, а также потребность опрошенных в соответствующей информации. Проанализировано 1 748 анкет. Результаты исследования. Избыточная масса тела выявлена у 15,6 ± 0,9 % женщин, разные степени ожирения – у 25,5 ± 1,0 % (p < 0,001). Опрошенные выделили 13 основных причин формирования избыточной массы тела и ожирения, на 1 женщину с нормальной массой тела пришлось в среднем 2,06 ± 0,21 причин, на женщин с избыточной массой тела – 4,19 ± 0,23 причин (p < 0,001), на женщин с ожирением – 5,42 ± 0,22 причин (p < 0,001). Первая группа женщин высказала потребность в среднем в 2,51 ± 0,28 формах информации по контролю и коррекции избы-точной массы тела и ожирения, вторая группа, соответственно, в 5,43 ± 0,35 формах (p < 0,001), третья группа – в 8,01 ± 0,32 формах. Заключение. Путем доступной разъяснительной работы на постоянной основе и соответствующем информационном обеспечении можно ограничить распространенность формирования избыточной массы тела и ожирения среди женщин. Необходима активизация органов родовспоможения по контролю и коррекции избыточной массы тела и ожирения среди женщин.

description: Evaluer la satisfaction des parties prenantes d’un dispositif d’enseignement au terme de celuici est une pratique courante dans le monde de la formation. S’il existe de nombreux apports théoriques permettant de produire des évaluations de la satisfaction de qualité, peu de recherches en éducation amènent des précisions sur les méthodes et les outils à mobiliser pour exploiter les résultats de ces évaluations afin d’améliorer le dispositif d’enseignement. Ce travail a pour perspective de contribuer au développement d’une méthode d’amélioration continue des dispositifs de formation sur la base de l’évaluation de la satisfaction des parties prenantes. Notre recherche s’inscrit dans la démarche de recherche développement en éducation telle qu’elle est préconisée par Harvey et Loiselle. Nous présentons les étapes qui ont conduit à la création du prototype de notre méthode. Nous détaillons son opérationnalisation dans le contexte des modules de préparation aux épreuves cantonales de références (ECR) et aux examens de certificat organisés par l’entreprise FuturPlus, entreprise privé active dans le soutien à la formation en Suisse romande. Notre méthode est ensuite révisée en fonction des résultats obtenus, dans le but d’être généralisable à d’autres contextes. La volonté de proposer une méthode basée sur des modèles théoriques valides et qui s’inscrive dans les pratiques actuelles du monde de la formation a guidé l’ensemble de notre recherche développement. Notre méthode prend en compte les exigences du label eduQua en termes d’amélioration continue. Elle est par ailleurs fondée sur des modèles éprouvés par la recherche tels que le modèle de Kirkpatrick, le modèle de paramétrage des actions didactiques (PAD), le cycle de Construction et de Gestion de la Qualité des Evaluations de la Satisfaction (CGQES) et la roue de Deming. Enfin, notre méthode d’amélioration mobilise le système KISS ainsi que les matrices de compatibilité pour accompagner la prise de décision quant aux modifications effectives à apporter au dispositif de formation évalué.

description: (Abridged) In the presence of a light WIMP (< 30 MeV), there are degeneracies among the nature of the WIMP, its couplings to standard model particles, its mass m_chi, and the number of equivalent neutrinos beyond the standard model, Delta N_nu. These degeneracies cannot be broken by the CMB constraint on the effective number of neutrinos, N_eff. However, big bang nucleosynthesis (BBN) is affected by a light WIMP and equivalent neutrinos, so the combination of BBN and CMB can break some of the degeneracies. Here, BBN predictions for abundances in the presence of a light WIMP and equivalent neutrinos are explored, and estimates of their observationally determined relic abundances are used to limit m_chi, Delta N_nu, and the present Universe baryon density (Omega_B h^2). These constraints are explored for Majorana and Dirac fermion WIMPs, as well as for real and complex scalar WIMPs that couple to electrons, positrons, and photons. In a separate paper this analysis is repeated for WIMPs that couple only to the standard model neutrinos, and constraints for the two cases are contrasted. Without a light WIMP but allowing for equivalent neutrinos, the combined BBN and CMB constraints favor N_eff = 3.46 +/- 0.17, Omega_B h^2 = 0.0224 +/- 0.0003, and Delta N_nu = 0.40 +/- 0.17. In this case, standard BBN (Delta N_nu = 0) is disfavored at ~98% confidence, and the presence of one sterile neutrino (Delta N_nu = 1) is disfavored at > 99% confidence. Allowing a light WIMP and Delta N_nu equivalent neutrinos together, the combined BBN and CMB data provide lower limits to the WIMP masses (> 0.5 - 5 MeV) that depend on the nature of the WIMP, favor m_chi ~8 MeV slightly over no WIMP, and loosen constraints on equivalent neutrinos, Delta N_nu = 0.65+0.46-0.35. While Delta N_nu = 0 is still disfavored at ~95% confidence with a light WIMP, Delta N_nu = 1 is now allowed.

description: We study the dynamical properties and space distribution of dark energy in the weak and strong gravitational fields caused by inhomogeneities of matter in the static world of galaxies and clusters. We show that the dark energy in the weak gravitational fields of matter density perturbations can condense or dilute, but amplitudes of its perturbations remain very small on all scales. We illustrate also how the "accretion" of the phantom dark energy onto the matter overdensity forms the dark energy underdensity. We analyze the behavior of dark energy in the gravitational fields of stars and black holes with the Schwarzschild metric. It is shown that, in the case of stars, the static solution of the differential equations for energy-momentum conservation exists and describes the distribution of density of dark energy inside and outside of a star. We have found that for stars and galaxies its value differs slightly from the average and is a bit higher for the quintessential scalar field as dark energy and a bit lower for the phantom one. The difference grows with the decrease of the effective sound speed of dark energy and is large in the neighborhood of neutron stars. We obtain and analyze also the solutions of equations that describe the stationary accretion of the dark energy as a test component onto the Schwarzschild black hole. It is shown that the rate of change of mass of the dark energy is positive in the case of quintessential dark energy and is negative in the case of the phantom one.

Surprisingly, the maximum charge for given mass is a nonsingular hairy black hole with nonzero Hawking temperature. The implications for Hawking evaporation are discussed.

description: A population of intermediate-mass black holes (BHs) is predicted to be freely floating in the Milky Way (MW) halo, due to gravitational wave recoil, ejection from triple BH systems, or tidal stripping in the dwarf galaxies that merged to make the MW. As these BHs traverse the gaseous MW disk, a bow shock forms, producing detectable radio and mm/sub-mm synchrotron emission from accelerated electrons. We calculate the synchrotron flux to be $\sim \rm 0.01-10\, mJy$ at GHz frequency, detectable by Jansky Very Large Array, and $\sim 10-100\,μ\rm Jy$ at $\sim10^{10}-10^{12} \,\rm Hz$ frequencies, detectable by Atacama Large Millimeter/sub-millimter Array. The discovery of the floating BH population will provide insights on the formation and merger history of the MW as well as on the evolution of massive BHs in the early Universe.

description: Theories with Planck-scale deformed symmetries exhibit quantum time evolution in which purity of the density matrix is not preserved. In particular we show that the non-trivial structure of momentum space of these models is reflected in a deformed action of translation generators on operators. Such action in the case of time translation generators leads to a Lindblad-like evolution equation for density matrices when expanded at leading order in the Planckian deformation parameter. This evolution equation is covariant under the deformed realization of Lorentz symmetries characterizing these models.

description: In a semi-abelian context, we study the condition (NH) asking that Higgins commutators of normal subobjects are normal subobjects. We provide examples of categories that do or do not satisfy this property. We focus on the relationship with the "Smith is Huq" condition (SH) and characterise those semi-abelian categories in which both (NH) and (SH) hold in terms of reflection and preservation properties of the change of base functors of the fibration of points.

description: An SDW antiferromagnetic (SDW-AF) low temperature phase transition is generally observe and the AF spin fluctuations are considered to play an important role for the superconductivity paring mechanism in FeAs superconductors. However, a similar magnetic phase transition is not observed in FeSe superconductors, which has caused considerable discussion. We report on the intrinsic electronic states of FeSe as elucidated by transport measurements under magnetic fields using a high quality single crystal. A mobility spectrum analysis, an ab initio method that does not make assumptions on the transport parameters in a multicarrier system, provides very import and clear evidence that another hidden order, most likely the symmetry broken from the tetragonal C4 symmetry to the C2 symmetry nematicity associated with the selective d-orbital splitting, exists in the case of superconducting FeSe other than the AF magnetic order spin fluctuations. The intrinsic low temperature phase in FeSe is in the almost compensated semimetallic states but is additionally accompanied by Dirac cone like ultrafast electrons $\sim$ 10$^4$cm$^2$(VS)$^{-1}$ as minority carriers.

Majorana fermions from Shiba states in an antiferromagnetic chain on top of a superconductor

description: We propose a new mechanism for topological superconductivity based on an antiferromagnetically ordered chain of magnetic atoms on the surface of a conventional superconductor. In a weak Zeeman field, a supercurrent in the substrate generates a staggered spin-current, which converts the preexisting topologically-unprotected Shiba states into Majorana fermions (MFs). The two experimental knobs can be finely tuned providing a platform with enhanced functionality for applications. Remarkably, the electronic spin-polarization of the arising edge MF wavefunctions depends solely on the parity of the number of magnetic moments, which can serve as a distinctive signature of the MFs. We introduce the basic concepts within a minimal model and make contact with experiments by a microscopic analysis based on the Shiba states.

description: We discuss the formalism of Balian and Duplantier for the calculation of the Casimir energy for an arbitrary smooth compact surface, and use it to give some examples: a finite cylinder with hemispherical caps, the torus, ellipsoid of revolution, a "cube" with rounded corners and edges, and a "drum" made of disks and part of a torus. We propose a model function which approximately captures the shape dependence of the Casimir energy.

title: Untangling the Confounded Relationship between Perceiver Sex and Walker Sex on the Bistable Perception of Emotion Displaying Point-light Walkers
Creators: name: Halovic, Shaun
Publisher: name: University of Sydney
Year: 2022

description: This data set describes the experimental data collected and reported in the article "Untangling the Confounded Relationship between Perceiver Sex and Walker Sex on the Bistable Perception of Emotion Displaying Point-light Walkers". This data set describes perceiver identification rates of point-light walkers displaying anger and fear. All point-light walker stimuli are provided here. Half of the perceivers were told that the point-light walkers were showed approaching them, whilst the other half were told that the walkers were walking away from them. We have separated the data by the sex of both perceiver and walker. We have also collapsed the data across both emotions and across both walker sexes. The data scores are presented as percentages/proportions of the number of times the perceiver correctly identified the emotion displayed by the point-light walker relative to the total number of point-light walkers viewed for that emotion.

description: S’inscrivant dans le champ de recherche des relations école-famille, ce travail a pour but principal d’apporter quelques éléments nouveaux au sujet de la construction du lien de confiance entre parents et enseignant.e.s. En effet, ces questions n’ont que peu, voire pas été étudiées quantitativement en Suisse jusqu’à ce jour. Ce travail vise premièrement à faire un état des lieux sur le niveau de confiance des parents d’un établissement primaire fribourgeois envers l’enseignant.e de leur enfant et à identifier des éventuels facteurs qui y sont liés. Il met ensuite en évidence les éléments qui, selon les parents, pourraient conduire à une augmentation de la confiance vis-à-vis de l’enseignant.e. Ici aussi, l’influence de différentes variables sur les réponses données est testée. Enfin, il fait état des principaux facteurs conduisant, selon les parents, à une diminution de la confiance envers les enseignant.e.s. Les données ont été recueillies auprès de 215 parents par le biais d’un questionnaire en ligne comportant des questions fermées et une question ouverte. Les résultats révèlent que le niveau de confiance parental est généralement élevé, mais qu’il est significativement plus haut au cycle I qu’au cycle II, avec une tendance à diminuer au fur et à mesure que l’enfant évolue dans les degrés scolaires primaires. Aucune association n’a été trouvée entre le niveau de confiance et le degré de diplôme parental, le genre du parent ou celui de l’enfant. La qualité de la relation maître-élève (particulièrement importante au cycle II), une communication régulière et bidirectionnelle ou encore l’organisation d’une journée "portes ouvertes" (spécialement pour le cycle I) ont été identifiés comme des éléments permettant de renforcer la confiance parentale. Enfin, le manque de communication et de collaboration a été perçu comme le facteur principal conduisant à une diminution de la confiance des parents. Des implications pour la création de relations collaboratives entre la famille et l’école en lien avec le renforcement de la confiance parentale sont en outre discutées.

description: Contexte : Depuis quelques décennies, l’institution scolaire tente de favoriser la collaboration école-famille. Parallèlement, de nombreuses injonctions internationales, dont la déclaration de Salamanque, invitent l’école à repenser son fonctionnement afin de tendre vers une école à visée inclusive. La Suisse n’échappe pas à ces injonctions et des solutions ont été mise en œuvre par les cantons en vue d’un changement de paradigme. Le concept 360° vaudois s’inscrit donc pleinement dans ce mouvement en incitant notamment la collaboration au sein de l’équipe pédagogique par le biais de regards croisés. Ainsi, les assistant·e·s à l’intégration (AI), dont la fonction auprès des élèves à besoins éducatifs particuliers est relativement récente, sont partie prenante de cette collaboration, tout comme les parents qui deviennent des intervenant·e·s à part entière. Ce travail s’intéresse donc à la collaboration entre les parents et les assistant·e·s à l’intégration afin de comprendre quelle est la place de ces derniers au sein de la collaboration école-famille. Méthodologie : Cette recherche qualitative se base sur l’étude de cas et l’approche phénoménologique, ceci afin d’apporter une vision proche des représentations sociales, permettant la compréhension de la construction des perceptions, des interactions mais aussi la réalité des pratiques et des besoins des individus dans une approche systémique. L’outil de récolte choisi est l’entretien semi-dirigé. Echantillon : Neuf participant·e·s ont été sélectionnés au total. Ainsi, quatre d’entre eux, dont l’AI, l’enseignante, la maman et la doyenne chargée de direction, interviennent auprès d’une élève de 1-2P et constituent le cas 1. Quant aux cinq autres, dont l’AI, l’enseignante, l’enseignante spécialisée, la maman et le directeur, interviennent auprès d’une élève à besoins particuliers de 3- 4P et constituent le cas 2. Résultats : Les principaux résultats mettent en lumière une collaboration établie sous différentes formes entre l’AI et les parents dépassant ainsi le cadre du cahier des charges mais également une distinction des rôles entre les enseignant·e·s et l’AI au sein de cette même collaboration. Après avoir mis en évidence des facilitateurs et des obstacles à cette collaboration, les résultats interrogent également la légitimité de l’AI dans ce domaine qui diffère selon le contexte.
