Didactique des langues et droits linguistiques de première catégorie. Enjeux et facteurs de l’intégration des immigrés en France
Creators: name: Agresti, Giovanni

description: Learning the language of the host country, in this case French in France, is a fundamental stage in the integration of immigrants, both linguistically and otherwise. This learning represents a ‘first category’ linguistic right because it enables immigrants, if they are sufficiently proficient in French, to really benefit from all the other fundamental rights (right to health, to education, to a fair trial, to freedom of expression, etc.). But this right to learn the official language, insofar as it determines the quality of life in society, and therefore also contributes to the security of that same society, is also a duty, an obligation imposed by the public authorities. Consequently, any language learning for immigrants can only be based on a sort of pact, or contract, between the immigrant and the State, which must provide the immigrant with the conditions to learn the language of the country effectively. In this contribution, we propose a three-stage approach: a) general considerations of a legal-linguistic nature; b) the presentation of essential elements that emerged from an exploratory field study recently carried out in France with two private organizations; c) methodological conclusions concerning, first and foremost, how to make the data speak, and how to analyse the (socio)linguistic and extralinguistic factors that are supposed to determine the quality or effectiveness of this learning.

description: We prove the hydrodynamic limit of a totally asymmetric zero range process on a torus with two lanes and randomly oriented edges. The asymmetry implies that the model is non-reversible. The random orientation of the edges is constructed in a bistochastic fashion which keeps the usual product distribution stationary for the quenched zero range model. It is also arranged to have no overall drift along the Z direction, which suggests diffusive scaling despite the asymmetry present in the dynamics. Indeed, using the relative entropy method, we prove the quenched hydrodynamic limit to be the heat equation with a diffusion coefficient depending on ergodic properties of the orientation of the edges. The zero range process on this graph turns out to be non-gradient. Our main novelty is the introduction of a local equilibrium measure which decomposes the vertices of the graph into components of constant density. A clever choice of these components eliminates the non-gradient problems that normally arise during the hydrodynamic limit procedure.

description: This article focuses on the 3Lgames4Prevention project, funded by the Horizon Europe program. It aims to prevent neurodegenerative disorders related to the gut microbiota by using serious games for foreign language learning. The experimental model involves adults aged 45 to 55, compared to a control group, to assess linguistic and social integration in a European context. The project is based on immersive serious games, proven effective for language learning, using Linguistic Landscape and Digital Storytelling as didactic methodologies. The scenario exploits cooking as a lever for adult foreign language learning. The interactive and multimodal virtual reality environment, created by participating professors and researchers, allows learners to prepare Canadian Christmas cake recipes in English. Furthermore, this article proposes a working hypothesis for FLE using two recipes as pedagogical support, exploited through digital applications and platforms to enhance learners' linguistic, intercultural, and communicative skills. The use of these digital tools stimulates learning, reduces anxiety, and offers an effective and enjoyable educational experience.

description: As redes sociais online, tais como o Facebook, estão cada vez mais inseridas na vida cotidiana das pessoas. Nelas são desenvolvidas diversos tipos de atividades por parte de seus usuários, que se apropriam de suas estruturaras como uma forma de extensão de seu mundo offline. Esta apropriação leva ao desenvolvimento de comunidades que tem como finalidade a preservação e compartilhamento de registro da memória local de cidades. Tais comunidades, por estarem presentes no ambiente online, deixam rastros que são passíveis de serem analisados de forma a entender a relação do público com o registro de memória local e o impacto deste tipo de conteúdo. Neste sentido este trabalho pretende usar os conceitos de Social Media Analytics para entender como é a dinâmica de uma página de memória local e o seu impacto enquanto lugar de preservação/compartilhamento dos registros de memória local. Para tanto foi escolhida a página do Facebook “Recife de Antigamente”, que possui um acervo online e audiovisual da cidade brasileira Recife, para a realização de um estudo de caso no período de 01/06/2017 a 30/04/2018.

Subjects: Dimension of vocabulary; orthographic vocabulary; phonological vocabulary; formal similarities; cognates

description: The aim of this study is to provide an in-depth analysis of the lexical knowledge of Italian learners of English as a foreign language. On one hand, we examine the presence of differences between the orthographic and phonological vocabularies, and on the other hand, we explore the role of formal similarity with the native language (L1). To achieve this goal, we administered to a group of 76 students from secondary school aged between 15 and 19, the V_Yes/No test (Meara, Miralpeix 2017) which we manipulated to evaluate both orthographic and phonological vocabulary. The results highlighted a clear superiority of orthographic vocabulary for all learners, regardless of their English proficiency level. Additionally, students consistently applied formal similarity criteria in lexical decision, more frequently recognizing cognate words compared to non-cognates. Results provide important insights for the assessment of the learners' vocabulary and for the development of teaching strategies aimed to enhance lexical development in L2 learners, emphasizing the importance of reinforcing oral vocabulary and encouraging awareness of formal similarities between languages.

A Primer On Political Economy In Static General Equilibrium

Publisher: name: Unknown

Subjects: Public Economics
Research Methods/ Statistical Methods

description: This paper highlights, illustrates and pulls together in a single model notions of political economy that are common to the static -general equilibrium literature. Political authority acts as though it forms preferences over the welfare of private agents from which policy functions are obtained that give the rule for the level to set a pre­determined policy instrument. However, the preference weights of the authority can be influenced by the lobbying behavior of private agents. A Nash game can determine the level of the preference weights, which in turn leads to a solution to instrument levels and, instantaneously, a market equilibrium for the economy. A distorted economy can thus exist indefinitely. How "outside" policy actions might alter the political equilibrium conclude the paper.
Mapping Campus Landscape Change Over Time

description: The University of British Columbia Vancouver campus has gone through numerous shifts in natural assets throughout recent history. Understanding how the green and grey infrastructure on campus has changed over time will help inform future biodiversity land use policy decisions. Urban forests on the UBC campus increase biodiversity by providing habitats for a rich array of flora and fauna. Buildings decrease in monetary value overtime, whereas an urban forest increases in value by providing more ecosystem services as the urban forest grows older. Many of the heritage trees on campus help protect the UBC community from the consequences of climate change. Trees can help mitigate climate change through ecosystem resilience, carbon sequestration and flood water mitigation. The urban forest at UBC also provides mental health benefits by lowering stress levels in students and increasing social wellbeing. Not only can urban forests mitigate and help us adapt to the impacts of climate change on the UBC campus, they also can restore and create a sense of community among UBC faculty and students. Dry summers in Vancouver are becoming the new normal, therefore our trees are now more vulnerable to biotic and abiotic disturbances such as disease, pests and wind throw. We are at risk of losing many of the benefits that urban forests provide to the UBC community. We need to increase the resiliency of the UBC urban forest to disturbances by strengthening biodiversity locally on campus. This SEEDS report uses orthophotos of the campus landscape to measure the building footprint change overtime. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community. The reader should bear in mind that this is a student project/report and is not an official document of UBC.

description: A pesquisa apresenta as características da avaliação por pares realizada nas revistas coletadas pelo Portal Brasileiro de Publicações Científicas em Acesso Aberto (oasisbr), assim como, apreende a opinião dos editores dessas revistas em relação aos diferentes modelos de avaliação por pares utilizados por revistas científicas. Para cumprir os objetivos propostos optou-se pelo questionário como instrumento de coleta de dados e pela abordagem quantitativa. O universo da pesquisa foi delimitado pelas revistas coletadas pelo Portal oasisbr que possuem cadastro no Diretório de Políticas Editoriais das Revistas Científicas Brasileiras (Diadorim). O questionário foi enviado para 637 revistas, destas, obtiveram-se 109 respostas, o que representa 17,1% do universo da pesquisa. O questionário buscou levantar a opinião dos editores a respeito das diferentes características que podem justificar a preferência por determinado modelo de avaliação por pares em detrimento de outros. Identificou-se a hegemonia da avaliação duplo cega como modelo que se constitui como mais solidificado, tanto na prática das revistas, quanto e no imaginário dos editores. Como demonstrado pela opinião dos editores, a preferência por esse modelo de avaliação se justifica, em essência, pela imparcialidade do processo que caracteriza o modelo. Percebe-se que os editores demonstram apreensão em relação as consequências que podem ser geradas quando se suprime o anonimato de um ou de ambos os protagonistas do processo de avaliação. Compreendem que, tanto o enviesamento ad hominem quanto represálias decorrentes de avaliações passadas, constituem as ações mais prejudiciais para a eficiência da avaliação por pares. Percebe-se, também, que as justificativas para adoção de outros modelos de avaliação não conseguiram modificar, de forma significativa, a opinião dos editores em relação a avaliação duplo cega, e as afirmações que buscaram justificar a avaliação duplo cega acabaram por confirmar a preferência pelo modelo.

description: It is well known that helical magnetic fields undergo a so-called inverse cascade by which their correlation length grows due to the conservation of magnetic helicity in classical ideal magnetohydrodynamics (MHD). At high energies above approximately $10$ MeV, however, classical MHD is necessarily extended to chiral MHD and then the conserved quantity is $\langle\mathcal{H}\rangle + 2 \langleμ_5\rangle / λ$ with $\langle\mathcal{H}\rangle$ being the mean magnetic helicity and $\langleμ_5\rangle$ being the mean chiral chemical potential of charged fermions. Here, $λ$ is a (phenomenological) chiral feedback parameter. In this paper, we study the evolution of the chiral MHD system with the initial condition of nonzero $\langle\mathcal{H}\rangle$ and vanishing $μ_5$. We present analytic derivations for the time evolution of $\langle\mathcal{H}\rangle$ and $\langleμ_5\rangle$ that we compare to a series of laminar and turbulent three-dimensional direct numerical simulations. We find that the late-time evolution of $\langle\mathcal{H}\rangle$ depends on the magnetic and kinetic Reynolds numbers ${\rm Re}_{_\mathrm{M}}$ and ${\rm Re}_{_\mathrm{K}}$. For a high ${\rm Re}_{_\mathrm{M}}$ and ${\rm Re}_{_\mathrm{K}}$ where turbulence occurs, $\langle\mathcal{H}\rangle$ eventually evolves in the same way as in classical ideal MHD where the inverse correlation length of the helical magnetic field scales with time $t$ as $k_\mathrm{p} \propto t^{-2/3}$. For a low Reynolds numbers where the velocity field is negligible, the scaling is changed to $k_\mathrm{p} \propto t^{-1/2}\mathrm{ln}\left(t/t_\mathrm{log}\right)$. After being rapidly generated, $\langleμ_5\rangle$ always decays together with $k_\mathrm{p}$, i.e. $\langleμ_5\rangle \approx k_\mathrm{p}$, with a time evolution that depends on whether the system is in the limit of low or high Reynolds numbers.

description: We report magnetization, susceptibility, electrical transport, and electron spin resonance (ESR) studies of single crystals of beta-AgNpO2(SeO3). Here the valence of the Np sites is expected to be Np(V). We observe a magnetic transition below 8 K, where the transition temperature is dependent on the effective magnetic moment. Although the transition appears to be ferromagnetic, no hysteresis is seen in the magnetization, and the saturation moment above 0.1 T is found to be about 60% of the free NpO2 ion moment. The decrease in the Np moments determined experimentally is thought to arise from crystal field and spin-orbit effects. Although Np(V) is expected to be ESR silent, we observe temperature dependent ESR spectra at ~44 GHz (for fields above the saturation field) that show slight shifts in the g-factor and line width at low temperatures. Our results provide evidence that both Np(V) and Np(IV) valences are present, where the latter may be a minority population. The crystals, although dark in appearance, are electrically insulating (rho > 10^10 Ohm-cm) at room temperature.

description: Map labeling is a classical problem in cartography and geographic information systems (GIS) that asks to place labels for area, line, and point features, with the goal to select and place the maximum number of independent, i.e., overlap-free, labels. A practically interesting case is point labeling with axis-parallel rectangular labels of common size. In a fully dynamic setting, at each time step, either a new label appears or an existing label disappears. Then, the challenge is to maintain a maximum cardinality subset of pairwise independent labels with sub-linear update time. Motivated by this, we study the maximal independent set ((MIS)) and maximum independent set (Max-IS) problems on fully dynamic (insertion/deletion model) sets of axis-parallel rectangles of two types -- (i) uniform height and width and (ii) uniform height and arbitrary width; both settings can be modeled as rectangle intersection graphs. We present the first deterministic algorithm for maintaining an MIS (and thus a 4-approximate Max-IS) of a dynamic set of uniform rectangles with polylogarithmic update time. This breaks the natural barrier of $Ω(Δ)$ update time (where $Δ$ is the maximum degree in the graph) for \emph{vertex updates} presented by Assadi et al. (STOC 2018). We continue by investigating Max-IS and provide a series of deterministic dynamic approximation schemes with approximation factors between 2 and 4 and corresponding running-time trade-offs. We have implemented our algorithms and reported the results of an experimental comparison exploring the trade-off between solution quality and update time for synthetic and real-world map labeling instances.

description: We introduce and discuss the Minimum Capacity-Preserving Subgraph (MCPS) problem: given a directed graph and a retention ratio $α\in (0,1)$, find the smallest subgraph that, for each pair of vertices $(u,v)$, preserves at least a fraction $α$ of a maximum $u$-$v$-flow's value. This problem originates from the practical setting of reducing the power consumption in a computer network: it models turning off as many links as possible while retaining the ability to transmit at least $α$ times the traffic compared to the original network.
 First we prove that MCPS is NP-hard already on a restricted set of directed acyclic graphs (DAGs) with unit edge capacities. Our reduction also shows that a closely related problem (which only considers the arguably most complicated core of the problem in the objective function) is NP-hard to approximate within a sublogarithmic factor already on DAGs. In terms of positive results, we present two algorithms that solve MCPS optimally on directed series-parallel graphs (DSPs): a simple linear-time algorithm for the special case of unit edge capacities and a cubic-time dynamic programming algorithm for the general case of non-uniform edge capacities. Further, we introduce the family of laminar series-parallel graphs (LSPs), a generalization of DSPs that also includes cyclic and very dense graphs. Their properties allow us to solve MCPS on LSPs by employing our DSP-algorithms as subroutines. In addition, we give a separate quadratic-time algorithm for MCPS on LSPs with unit edge capacities that also yields straightforward quadratic time algorithms for several related problems such as Minimum Equivalent Digraph and Directed Hamiltonian Cycle on LSPs.

description: We investigate the gravitational lensing properties of dark matter halos with Burkert profiles. We derive an analytic expression for the lens equation and use it to compute the magnification, impact parameter and image separations for strong lensing. For the scaling relation that provides the best fits to spiral-galaxy rotation curve data, Burkert halos will not produce strong lensing, even if this scaling relation extends up to masses of galaxy clusters. Tests of a simple model of an exponential stellar disk superimposed on a Burkert-profile halo demonstrate that strong lensing is unlikely without an additional concentration of mass in the galaxy center (e.g. a bulge). The fact that most strong lenses on galactic scales are elliptical galaxies suggests that a strong central concentration of baryons is required to produce image splitting. This solution is less attractive for clusters of galaxies, which are generally considered to be dark-matter dominated even at small radii. There are three possible implications of these results: (1) dark halos may have a variety of inner profiles (2) dark matter halos may not follow a single scaling relation from galaxy scale up to cluster scale and/or (3) the splitting of images (even by clusters of galaxies) may in general be due to the central concentration of baryonic material in halos rather than dark matter.

description: A formação em Ciência da Informação (CI) caracteriza-se pela diversidade de modelos com repercussão nos respetivos cursos de Mestrado e Doutoramento. Dada a importância destes para a afirmação da área pretende-se fornecer subsídios para uma reflexão sobre a mesma, contextualizando-a na contemporaneidade a partir dos referenciais fornecidos pelos referidos cursos em Portugal e no Brasil. Objetivou-se: i. Identificar nestes dois países, os cursos ativos (2016) certificados pelas respetivas agências; ii. Verificar o enquadramento oficial; iii. Contextualizar a CI nas classificações em uso nas estruturas oficiais educativas. Seguiu-se uma metodologia qualitativa exploratória assente na análise e síntese dos dados obtidos nas fontes oficiais. Identificaram-se, respetivamente, em Portugal e no Brasil: mestrados – 4 e 16 e doutoramentos – 3 e 9. A área, em Portugal, apresenta-se como em passagem das «Ciências Documentais» para uma CI mais abrangente; no Brasil, observa-se um complexo relacionamento entre a Biblioteconomia, a Arquivologia e a CI, consubstanciado na procura da identidade da CI e, simultaneamente, na afirmação autónoma das disciplinas envolvidas. Infere-se uma relação entre este panorama e os distintos contextos geográficos Europa e América.

description: We consider the effective superpotentials of N=1 SU(N_c) and U(N_c) supersymmetric gauge theories that are obtained from the N=2 theory by adding a tree-level superpotential. We show that several of the techniques for computing the effective superpotential are implicitly regularized by 2N_c massive fundamental quarks, i.e. the theory is embedded in the finite theory with nontrivial UV fixed point. In order to study N=1 and N=2 theories with fundamentals, we explicitly factorize the Seiberg-Witten curve for N_f != 0 and compare to the known form of the N=1 superpotential. N=2 gauge theories have an underlying integrable structure, and we obtain results on a new Lax matrix for N_f = N_c.

description: Vários estudos têm referido o impacto positivo que o recurso à Leitura Assistida por Animais tem na aprendizagem da leitura. Integrado no programa “Ler + Feliz” da Biblioteca Municipal de Silves, o projeto “L.E.R. Cãofiante" em 2015-2016, apoiou alunos de duas turmas de 1º ano. Mensalmente, estes participavam numa sessão de mediação do livro e da leitura, com a bibliotecária e os seus cães, para além de terem acesso a livros diversificados e de qualidade. Neste estudo participaram 80 crianças do 1º ano, 47 das quais integradas nas turmas do projeto e 33 no grupo de controlo. As famílias responderam a questionários no início e final do ano letivo. As crianças e professoras fizeram o registo das leituras realizadas e como estas decorreram. Os dados foram tratados recorrendo à ANOVA para medidas repetidas. Pudemos constatar um aumento da frequência de práticas lúdicas em família e do tempo de leitura em casa, entre o início e o fim do ano letivo, significativamente superior nas crianças participantes no projeto. Os registos das professoras e dos alunos confirmam a regularidade da leitura durante a participação do projeto e a importância que a intervenção teve para a despoletar.

Stability of quantum Fourier transformation on Ising quantum computer

description: We analyze the influence of errors on the implementation of the quantum Fourier transformation (QFT) on the Ising quantum computer (IQC). Two kinds of errors are studied: (i) due to spurious transitions caused by pulses and (ii) due to external perturbation. The scaling of errors with system parameters and number of qubits is explained. We use two different procedures to fight each of them. To suppress spurious transitions we use correcting pulses (generalized $2πk$ method) while to suppress errors due to external perturbation we use an improved QFT algorithm. As a result, the fidelity of quantum computation is increased by several orders of magnitude and is thus stable in a much wider range of physical parameters.

Scaling limits of linear random fields on ${\mathbb{Z}}^2$ with general dependence axis
Creators: name: Pilipauskaitė, Vytautė

Publisher: name: arXiv
Year: 2020
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We discuss anisotropic scaling of long-range dependent linear random fields $X$ on ${\mathbb{Z}}^2$ with arbitrary dependence axis (direction in the plane along which the moving-average coefficients decay at a smallest rate). The scaling limits are taken over rectangles whose sides are parallel to the coordinate axes and increase as $λ$ and $λ^γ$ when $λ\to \infty$, for any $γ>0$. The scaling transition occurs at $γ^X_0 >0$ if the scaling limits of $X$ are different and do not depend on $γ$ for $γ> γ^X_0 $ and $γ< γ^X_0$. We prove that the fact of `oblique' dependence axis (or incongruous scaling) dramatically changes the scaling transition in the above model so that $γ_0^X = 1$ independently of other parameters, contrasting the results in Pilipauskaitė and Surgailis (2017) on the scaling transition under congruous scaling.
The Globular Cluster Luminosity Function: New Progress in Understanding an Old Distance Indicator

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: I review the Globular Cluster Luminosity Function (GCLF) with emphasis on recent observational data and theoretical progress. As is well known, the turn-over magnitude (TOM) is a good distance indicator for early-type galaxies within the limits set by data quality and sufficient number of objects. A comparison with distances derived from surface brightness fluctuations with the available TOMs in the V-band reveals, however, many discrepant cases. These cases often violate the condition that the TOM should only be used as a distance indicator in old globular cluster systems. The existence of intermediate age-populations in early-type galaxies likely is the cause of many of these discrepancies. The connection between the luminosity functions of young and old cluster systems is discussed on the basis of modelling the dynamical evolution of cluster systems. Finally, I briefly present the current ideas of why such a universal structure as the GCLF exists.

Load Balancing with Job-Size Testing: Performance Improvement or Degradation?

description: In the context of decision making under explorable uncertainty, scheduling with testing is a powerful technique used in the management of computer systems to improve performance via better job-dispatching decisions. Upon job arrival, a scheduler may run some \emph{testing algorithm} against the job to extract some information about its structure, e.g., its size, and properly classify it. The acquisition of such knowledge comes with a cost because the testing algorithm delays the dispatching decisions, though this is under control. In this paper, we analyze the impact of such extra cost in a load balancing setting by investigating the following questions: does it really pay off to test jobs? If so, under which conditions? Under mild assumptions connecting the information extracted by the testing algorithm in relationship with its running time, we show that whether scheduling with testing brings a performance degradation or improvement strongly depends on the traffic conditions, system size and the coefficient of variation of job sizes. Thus, the general answer to the above questions is non-trivial and some care should be considered when deploying a testing policy. Our results are achieved by proposing a load balancing model for scheduling with testing that we analyze in two limiting regimes. When the number of servers grows to infinity in proportion to the network demand, we show that job-size testing actually degrades performance unless short jobs can be predicted reliably almost instantaneously and the network load is sufficiently high. When the coefficient of variation of job sizes grows to infinity, we construct testing policies inducing an arbitrarily large performance gain with respect to running jobs untested.
