description: This paper provides a new method for decomposing segregation indices depending on two distinct set of unities. This method is applied to analyse how restrictive zoning and parental school choices impact social diversity in French middle schools. Using an exhaustive geolocalized dataset on three urban areas, segregation indices at the school level are decomposed into contributions of residential segregation and of circumvention. According to the results, for the three analysed urban areas, school choice accounts for one half of the social segregation across middle schools in Paris, and more than one third in the urban areas of Bordeaux and Clermond-Ferrand. This mostly stems from the fact that the social mix in "left behind" public schools is reduced as the parents who opt out of their neighborhood school for a private one are often the most advantaged ones locally.
description: Ce document propose une nouvelle méthode de décomposition des indices de ségrégation, lorsque les unités sont réparties suivant deux partitions non disjointes. Cette méthode est appliquée pour étudier comment la sectorisation et les choix parentaux contribuent à la ségrégation sociale dans les collèges français. A partir des données géolocalisées exhaustives sur trois zones urbaines, nous décomposons les indices de ségrégation entre collèges en fonction de la contribution de la ségrégation résidentielle et du contournement de la carte scolaire. Le choix d'une partie des parents de ne pas scolariser leur enfant dans le collège de secteur, contribue pour moitié à la ségrégation sociale à Paris, et pour plus de deux tiers dans les agglomérations de Bordeaux et de Clermond-Ferrand. Cet effet est surtout attribuable à la réduction de la diversité des origines sociales dans certains collèges publics, les familles évitant le collège de quartier pour un collège privé étant souvent les plus favorisées localement.

description: We introduce a Green's function method for handling radiative effects on false vacuum decay. In addition to the usual thin-wall approximation, we achieve further simplification by treating the bubble wall in the planar limit. As an application, we take the $λϕ^4$ theory, extended with $N$ additional heavier scalars, wherein we calculate analytically both the functional determinant of the quadratic fluctuations about the classical soliton configuration and the first correction to the soliton configuration itself.

description: In the early morning hours of 30 December 2020, thousands of protesters surrounded the Argentine parliament. With their masks and green handkerchiefs – the symbol of the National Campaign for Legal, Safe and Free Abortion (NCRLSA) – the crowds celebrated the vote that turned Argentina into the largest Latin American country to legalize abortion. Since the 1970s, Argentine feminist groups have struggled for the right over their own bodies. After decades of activism, the NCRLSA was founded in 2005 as a result of coordinated activities across more than 305 grassroots organizations, from catholic groups to leftist movements.

description: Supplementing palm kernel meal (PKM)-based diet with an exogenous enzyme can help to improve the utilization and minimize the negative consequences of the high fiber and antinutritional factors on the performance and health of animals. Forty weaned male pigs with an average initial weight of 7.85 ± 0.31 kg were used to determine the effects of supplementing a PKM-based diet with enzyme inclusion, on blood parameters, carcass, and organ characteristics. Pigs were allotted to four diets which include the control diet containing 55% PKM while the addition of 1, 2 and 3 g/kg enzyme cocktail was tested in a complete randomized design trial that lasted seven weeks. Feed and water were provided ad-lib and blood sampled via jugular vein after the trial. Pigs fed diets containing high PKM with or without enzyme, did not manifest any significant deviation in their haematology or serum variables. Enzyme inclusions reduce cholesterol concentrations (p<0.05), but no linear or quadratic effect of the enzyme was observed on alkaline phosphatase or creatinine concentration (p>0.05). Eviscerated weight increased (p<0.05) as enzyme inclusion increased but other carcass traits were not affected. Pancreas and empty stomach weights reduced quadratically with enzyme inclusion (p<0.05) and this may ostensibly be due to improved digestive activities of the organs. This study confirms that the inclusion of enzyme in diets containing high proportion of PKM does not have any nega?tive physiological effect on growing pig.

description: Recently, the dynamical and spectral properties of square-free integers, visible lattice points and various generalisations have received increased attention. One reason is the connection of one-dimensional examples such as $\mathscr B$-free numbers with Sarnak's conjecture on the `randomness' of the Möbius function, another the explicit computability of correlation functions as well as eigenfunctions for these systems together with intrinsic ergodicity properties. Here, we summarise some of the results, with focus on spectral and dynamical aspects, and expand a little on the implications for mathematical diffraction theory.

description: We have studied nuclear fusion reactions from the Coulomb explosion of deuterium clusters induced by high-intensity laser beams within a transport approach. By incorporating the D+D $\rightarrow$ n + He$^3$ channel as inelastic collisions based on the stochastic method, we have calibrated the neutron yield from the simulation in a box system with that from the reaction rate equation. After justifying the Coulomb explosion of a single cluster by comparing results with available theoretical limits, we have then investigated the dynamics from Coulomb explosions of systems with different cluster numbers and different deuteron numbers in clusters. We find that the kinetic energy spectrum of deuterons at the final stage is different from that when neutrons are abundantly produced, corresponding to significantly different reaction rates. We also extrapolate the neutron yield result from small systems to large systems based on an intuitive parameterized form and compare with the available experimental result. The present framework can be extended by incorporating more channels, and useful for further studies of nuclear fusion reactions in plasma systems at higher energies reached in more recent experiments.

description: Drawing on a unique, large sample survey from France, Trajectories and Origins (TeO), this article aims to disentangle the effects of migrants' initial legal status from their pre-migration characteristics on five outcomes : family income, unemployment, neighborhood income disadvantage, segregation and self-rated health. Findings show that outcomes vary by legal status, but that most of these disparities disappear once pre-migration variables are accounted for. Still, we find net effects of legal status for some categories. Asylum seekers tend to face greater disadvantage in terms of family income and segregation, while students report higher family income and lower neighborhood income disadvantage. Migrants with worker status or a French spouse permit also tend to experience less neighborhood income disadvantage and segregation. Yet interactions between legal status and country of origin show that these effects are not constant across groups. Sub-Saharan Africans and migrants from other non-European countries are the most strongly impacted by disadvantaged status.
Magnetic Drag and 3-D Effects in Theoretical High-Resolution Emission Spectra of Ultrahot Jupiters: the Case of WASP-76b

description: Ultrahot Jupiters are ideal candidates to explore with high-resolution emission spectra. Detailed theoretical studies are necessary to investigate the range of spectra we can expect to see from these objects throughout their orbit, because of the extreme temperature and chemical longitudinal gradients that exist across day and nightside regions. Using previously published 3D GCM models of WASP-76b with different treatments of magnetic drag, we post-process the 3D atmospheres to generate high-resolution emission spectra for two wavelength ranges and throughout the planet's orbit. We find that the high-resolution emission spectra vary strongly as a function of phase, at times showing emission features, absorption features, or both, which are a direct result of the 3D structure of the planet. At phases exhibiting both emission and absorption features, the Doppler shift differs in direction between the two spectral features, making them differentiable instead of canceling each other out. Through the use of cross-correlation, we find different patterns in net Doppler shift for models with different treatments of drag: the nightside spectra show opposite signs in their Doppler shift, while the dayside phases have a reversal in the trend of net shift with phase. Finally, we caution researchers from using a single spectral template throughout the planet's orbit; this can bias the corresponding net Doppler shift returned, as it can pick up on a bright region on the edge of the planet disk that is highly red- or blue-shifted.

description: Since mid-1990s social sciences have re-started to give attention to the role played by the state in promoting economic growth, with important contributions from economists, sociologists and political scientists. This attention further increased after the economic and financial crisis of 2007/08 with a rising strand of research that is focusing on the institutional foundations of different growth models in advanced economies. This paper is related to this wide strand of research and analyses how industrial policies can favor the emerging of institutional conditions that are conducive to economic growth. In particular, the paper analyzes the neglected relationship between public policies and labor productivity in OECD countries. The focus is on four policy arenas that have a direct impact on labor productivity: labor market, human capital, innovation and on the efficiency of public administration. The analysis underlines a strong association between labour productivity and public policies addressed to promote training and activation, tha quality of educational institutions and inter-institutional networks in innovation. Other kind of policies, such as those addressed to flexibilise the labour market or to reduce labour costs or to increase the average number of years of schooling seem to play a minor role.
THE EFFECTS OF ESTROGEN AND INFLAMMATION ON THE EXPRESSION, ACTIVITY, AND RELATIVE ABUNDANCE OF APO AND HOLO CERULOPLASMIN

description: Ceruloplasmin (Cp) is a 132 kDa glycoprotein involved in copper trafficking, iron oxidation, and reactive-oxygen-species neutralization. The vast majority of copper (50-80%) in mammalian blood plasma is associated with Cp, making it the primary mechanism of copper transport to cells. Cp is initially synthesized as the copper-less inactive Apo form in the liver, then metalated with six Cu1+ ions to form Holo Cp. Holo Cp is enzymatically active and reverts to the Apo form upon donation of copper to cells. Previous research has indicated that Apo and Holo Cp are roughly equally abundant under normal conditions, but their expression, abundance, and activity are altered by estrogen and acute inflammation. Our main goal was to establish an antibody-based method for detecting Apo and Holo Cp independently, and to study how their expression, activity, and relative abundance change during estrogen treatment and acute inflammation. It was found that 14 days of estrogen treatment induced a tripling in Cp enzyme activity and increased the abundance of Apo Cp relative to Holo Cp without changing Cp mRNA abundance in female Sprague Dawley rats. We also found that Cp mRNA levels spike 16 hours after induction of inflammation with turpentine and return to normal levels after 24 hours. This expression spike was followed by a tripling of Cp enzyme activity in the blood, which reached its maximum level after 48 hours and returned to control levels after 14 days. The abundance of Apo Cp relative to Holo Cp steadily decreased over the 48-hour period studied, suggesting that the ratio of the two forms changes during disruptions in homeostasis. Thus, the expression, activity, and relative abundance of Apo and Holo Cp are strongly modulated by both elevated estrogen levels and the inflammatory response in female Sprague Dawley rats.

description: This study investigated the living conditions of the eZakheleni informal settlement, Durban metropolis of Kwazulu-Natal, South Africa. The utilized data were collected with the use of a well-structured questionnaire through a multistage sampling of 255 households. The descriptive results indicated low levels of educational attainment, a large number of female-headed households, high unemployment rates, inadequate sources of income, the poor security and low government intervention programmes. The results of inferential analysis indicate that factors such as water accessibility, toilet accessibility, years of working experience, food security status, educational status and access to good health were the significant factors that were key to improving the living conditions of the residents in the study area. The study therefore concluded that education, basic housing services (water accessibility, toilet accessibility), food security, working experience, social connectivity and health are key contributors to households’ living condition in the study area and recommended several future research and policy directions which could improve the living conditions of the informal settlement.

description: Non-Planckian (NP) spectral modifications of the CMB radiation spectrum can be produced due to the existence of a non-zero value of the plasma frequency at the recombination epoch. We present here an analysis of NP effects on the radio cosmological background and we derive, for the first time, predictions of their amplitude on three different observables: the CMB spectrum, the Sunyaev-Zel'dovich (SZ) effect in cosmic structures, and the 21-cm background temperature brightness change. We find that NP effect can manifest in the CMB spectrum at $ν\simlt 400$ MHz as a drastic cut-off in the CMB intensity. Using the available CMB data in the relevant $ν$ range (i.e., mainly at $\simlt 1$ GHz and in the COBE-FIRAS data frequency range), we derive upper limits on the plasma frequency $ν_p$ = 206, 346 and 418 MHz at 1, 2 and 3 $σ$ confidence level, respectively. We find that the difference between the pure Planck spectrum and the one modified by NP effects is of the order of mJy/arcmin$^2$ at $ν\simlt 0.5$ GHz and it becomes smaller at higher frequencies where it is $\sim 0.1$ mJy/arcmin$^2$ at $ν\simgt 150$ GHz, thus indicating that the experimental route to probe NP effects in the early universe is to observe the radio cosmological background at very low frequencies.(abridged)

description: Robustness is becoming another important challenge of federated learning in that the data collection process in each client is naturally accompanied by noisy labels. However, it is far more complex and challenging owing to varying levels of data heterogeneity and noise over clients, which exacerbates the client-to-client performance discrepancy. In this work, we propose a robust federated learning method called FedRN, which exploits k-reliable neighbors with high data expertise or similarity. Our method helps mitigate the gap between low- and high-performance clients by training only with a selected set of clean examples, identified by their ensembled mixture models. We demonstrate the superiority of FedRN via extensive evaluations on three real-world or synthetic benchmark datasets. Compared with existing robust training methods, the results show that FedRN significantly improves the test accuracy in the presence of noisy labels.

description: For classical relativistic field theory in Minkowski space-time, the addition of a superpotential term to a conserved current density is trivial in the sense that it does not modify the local conservation law nor change the conserved charge, though it may allow us to obtain a current density with some improved properties. The addition of a total derivative term to a Lagrangian density is also trivial in the sense that it does not modify the equations of motion of the theory. These facts suggest that both operations are related and possibly equivalent to each other for any global symmetry of an action functional. We address this question following the study of two quite different (and well known) instances: the Callan-Coleman-Jackiw improvement of the canonical energy-momentum tensor for scalar and vector fields (providing an on-shell traceless energy-momentum tensor) and the construction of a current density satisfying a zero curvature condition for two-dimensional sigma models on deformed spaces (notably the squashed three-sphere and warped AdS spaces). These instances correspond to fairly different implementations of the general results. An appendix addresses the precise relationship between the approaches to local conservation laws based on active and passive symmetry transformations, respectively.

description: Can large immigration inflows impact electoral outcomes and specifically, what impact did immigration have on the vote in favour of leaving the European Union (Brexit) in the United Kingdom? In particular, I focus on how the increase in Polish immigration, the major group of immigrants post 2004, affected votes in favour of leaving the EU. I find a percentage point increase in Polish immigration to the UK to have caused an increase in votes in favour of Brexit of about 2.72-3.12 percentage points, depending on the specification. To obtain exogenous variation in Polish immigration, I collect data from the archives that reveals the location of Polish War Resettlement Camps after Word War II, which location is plausibly exogenous to current political outcomes. Discussing potential mechanisms, I examine public opinion data in the British Election Study 2015 and find evidence of adversity towards immigration to be a root cause. Other considerations such as the National Health Service (NHS), incumbency and the general trust in politicians as well as the political institutions seem not to play a role.

description: Machine learning and geostatistics are powerful mathematical frameworks for modeling spatial data. Both approaches, however, suffer from poor scaling of the required computational resources for large data applications. We present the Stochastic Local Interaction (SLI) model, which employs a local representation to improve computational efficiency. SLI combines geostatistics and machine learning with ideas from statistical physics and computational geometry. It is based on a joint probability density function defined by an energy functional which involves local interactions implemented by means of kernel functions with adaptive local kernel bandwidths. SLI is expressed in terms of an explicit, typically sparse, precision (inverse covariance) matrix. This representation leads to a semi-analytical expression for interpolation (prediction), which is valid in any number of dimensions and avoids the computationally costly covariance matrix inversion.

description: Modeling perception is critical for many applications and developments in computer graphics to optimize and evaluate content generation techniques. Most of the work to date has focused on central (foveal) vision. However, this is insufficient for novel wide-field-of-view display devices, such as virtual and augmented reality headsets. Furthermore, the perceptual models proposed for the fovea do not readily extend to the off-center, peripheral visual field, where human perception is drastically different. In this paper, we focus on modeling the temporal aspect of visual perception in the periphery. We present new psychophysical experiments that measure the sensitivity of human observers to different spatio-temporal stimuli across a wide field of view. We use the collected data to build a perceptual model for the visibility of temporal changes at different eccentricities in complex video content. Finally, we discuss, demonstrate, and evaluate several problems that can be addressed using our technique. First, we show how our model enables injecting new content into the periphery without distracting the viewer, and we discuss the link between the model and human attention. Second, we demonstrate how foveated rendering methods can be evaluated and optimized to limit the visibility of temporal aliasing.

description:  Le bruit médiatique autour des multinationales visées par la corruption affaiblit-il la capacité de leurs dirigeants à obtenir des gouvernements des décisions conformes à leurs préférences ? Pour répondre à cette question, cet article entreprend une comparaison intra-cas se déroulant au Québec et au Canada entre 2011 et 2018, et portant sur : les enquêtes et accusations de corruption touchant la multinationale du génie-conseil, SNC Lavalin; la couverture de ces événements dans la presse écrite, et les nouvelles règles de lutte à la corruption d'entreprise adoptées durant cette période par les gouvernements provincial et fédéral. Durant ces années, et malgré les mauvaises nouvelles concernant SNC Lavalin, les gouvernements provincial et fédéral ont pris des décisions permettant à la firme d'éviter une reconnaissance de culpabilité civile et criminelle, et de préserver ses contrats publics. Pour expliquer ces résultats, l'hypothèse du nationalisme économique comme "cadre" est mise de l'avant. Lorsque les sanctions pour punir les entreprises touchées par la corruption sont définies (framed) comme des coûts qui menacent l'économie nationale ou du pays, le bruit autour des scandales de corruption importe peu. Il est neutralisé par le nationalisme économique, que les dirigeants de firmes mobilisent pour construire des coalitions de soutien en faveur de politiques anticorruption plus clémentes; qui ne désavantagent pas "nos entreprises" face à leurs concurrents étrangers.

It is done by a direct resolution of the defining equation of the star-exponential and produces an expression with Bessel functions. This yields a continuous group homomorphism from SL(2,R) into the von Neumann algebra of multipliers of the Hilbert algebra underlied by this natural star-product. As an application, we prove a new identity on Bessel functions.

description: Reusing ontologies in practice is still very challenging, especially when multiple ontologies are (jointly) involved. Moreover, despite recent advances, the realization of systematic ontology quality assurance remains a difficult problem. In this work, the quality of thirty biomedical ontologies, and the Computer Science Ontology are investigated, from the perspective of a practical use case. Special scrutiny is given to cross-ontology references, which are vital for combining ontologies. Diverse methods to detect potential issues are proposed, including natural language processing and network analysis. Moreover, several suggestions for improving ontologies and their quality assurance processes are presented. It is argued that while the advancing automatic tools for ontology quality assurance are crucial for ontology improvement, they will not solve the problem entirely. It is ontology reuse that is the ultimate method for continuously verifying and improving ontology quality, as well as for guiding its future development. Specifically, multiple issues can be found and fixed primarily through practical and diverse ontology reuse scenarios.

description: We consider the dynamics of rotational excitations placed on a single molecule in spatially disordered 1D, 2D and 3D ensembles of ultracold molecules trapped in optical lattices. The disorder arises from incomplete populations of optical lattices with molecules. This leads to a model corresponding to a quantum particle with long-range tunnelling amplitudes moving on a lattice with the same on-site energy but with forbidden access to random sites (vacancies). We examine the time and length scales of Anderson localization for this type of disorder with realistic experimental parameters in the Hamiltonian. We show that for an experimentally realized system of KRb molecules on an optical lattice this type of disorder leads to disorder-induced localization in 1D and 2D systems on a time scale $t \sim 1$ sec. For 3D lattices with $55$ sites in each dimension and vacancy concentration $ 90~\%$, the rotational excitations diffuse to the edges of the lattice and show no signature of Anderson localization. We examine the role of the long-range tunnelling amplitudes allowing for transfer of rotational excitations between distant lattice sites. Our results show that the long-range tunnelling has little impact on the dynamics in the diffusive regime but affects significantly the localization dynamics in lattices with large concentrations of vacancies, enhancing the width of the localized distributions in 2D lattices by more than a factor of 2. Our results raise a general question whether quantum particles with long-range tunnelling can undergo quantum localization in 3D lattices with substitutional disorder.

description: Spatially homogeneous cosmological spacetimes, evolving in the presence of a positive cosmological constant and matter satisfying some reasonable energy conditions, typically approach the de Sitter geometry asymptotically (at least locally). In this work, we propose an alternate way to characterize this phenomena. We focus on a subset of such models admitting a generalized Kerr-Schild representation. We argue that the functions which define such a representation can be chosen, such that, their asymptotic behavior make the evolution towards the de Sitter spacetime manifest through the representation. We verify our claim for the Kantowski-Sachs family of cosmological spacetimes.

description: Cross-domain few-shot learning (CD-FSL), where there are few target samples under extreme differences between source and target domains, has recently attracted huge attention. Recent studies on CD-FSL generally focus on transfer learning based approaches, where a neural network is pre-trained on popular labeled source domain datasets and then transferred to target domain data. Although the labeled datasets may provide suitable initial parameters for the target data, the domain difference between the source and target might hinder fine-tuning on the target domain. This paper proposes a simple yet powerful method that re-randomizes the parameters fitted on the source domain before adapting to the target data. The re-randomization resets source-specific parameters of the source pre-trained model and thus facilitates fine-tuning on the target domain, improving few-shot performance.

description: The COVID-19 pandemic is the first to have emerged when Next Generation Sequencing was readily available and it has played the major role in following evolution of the causative agent, Severe Acute Respiratory Syndrome Coronavirus 2. Response to the pandemic was greatly facilitated though use of existing influenza surveillance networks: World Health Organization (WHO) Global Influenza Surveillance and Response System (GISRS), focussing largely on human influenza, and the OFFLU network of expertise on avian influenza established by the Food and Agricultural Organization of the United Nations (FAO) and the World Organization for Animal Health (WOAH). Data collection/deposition platforms associated with these networks, notably WHO's FluNet and the Global Initiative on Sharing All Influenza Data (GISAID) were/are being used intensely. Measures introduced to combat COVID-19 resulted in greatly decreased circulation of human seasonal influenza viruses for approximately 2 years, but circulation continued in the animal sector with an upsurge in the spread of highly pathogenic avian influenza subtype H5N1 with large numbers of wild bird deaths, culling of many poultry flocks and sporadic spill over into mammalian species, including humans, thereby increasing pandemic risk potential. While there are proposals/implementations to extend use of GISRS and GISAID to other infectious disease agents (e.g. Respiratory Syncytial Virus and Monkeypox), there is need to ensure that influenza surveillance is maintained and improved in both human and animal sectors in a sustainable manner to be truly prepared (early detection) for the next influenza pandemic.
Occupancy Flow Fields for Motion Forecasting in Autonomous Driving

description: We propose Occupancy Flow Fields, a new representation for motion forecasting of multiple agents, an important task in autonomous driving. Our representation is a spatio-temporal grid with each grid cell containing both the probability of the cell being occupied by any agent, and a two-dimensional flow vector representing the direction and magnitude of the motion in that cell. Our method successfully mitigates shortcomings of the two most commonly-used representations for motion forecasting: trajectory sets and occupancy grids. Although occupancy grids efficiently represent the probabilistic location of many agents jointly, they do not capture agent motion and lose the agent identities. To this end, we propose a deep learning architecture that generates Occupancy Flow Fields with the help of a new flow trace loss that establishes consistency between the occupancy and flow predictions. We demonstrate the effectiveness of our approach using three metrics on occupancy prediction, motion estimation, and agent ID recovery. In addition, we introduce the problem of predicting speculative agents, which are currently-occluded agents that may appear in the future through dis-occlusion or by entering the field of view. We report experimental results on a large in-house autonomous driving dataset and the public INTERACTION dataset, and show that our model outperforms state-of-the-art models.

description: Urban transformation has become a significant concept in the process of growth and change in modern cities. This doctoral thesis, titled "Preserving Urbanization and City Memory in Urban Transformation for the Future," explores the interaction between urban transformation and the process of urbanization, as well as how city memory can be preserved and sustained within this context. The thesis emphasizes the critical importance of city memory in preserving a city's identity and character. In this context, an analysis is presented that suggests urban transformation should consider not only the physical structures but also the cultural and historical elements. The study conducts a detailed examination of various urban transformation projects implemented in different cities and analyzes their impact on the local community's way of life, history, culture, and social dynamics. The research highlights the significance of a sustainable urbanization model that carries the past and culture into the future. The findings of the thesis reveal that city memory needs to be preserved during urban transformation, but it is often overlooked in favor of economic benefits. Furthermore, it is concluded that the city memory to be carried into the future must be integrated into transformation plans that address the social and cultural needs of the community. The study argues that urban transformation should be perceived and implemented as an integral part of the urbanization process. Additionally, it advocates for treating city memory as a strategic component within this process. This work can serve as a valuable reference for urban planners, architects, historians, and other relevant stakeholders, providing a comprehensive guide on how to consider and preserve city memory during urban transformation.

description: Over the past two decades, a growing number of randomised controlled trials have assessed the impact on children's language skills of interventions encouraging parents to read books to their children. We present the results of a meta-analysis of the impact of 30 such interventions. Results indicate that they are often ineffective, and that only one specific methodology (dialogic reading), displays systematically positive impacts. Moreover, effective interventions display weaker impacts on low-socioeconomic groups, thus raising equity issues, and on younger children. Our systematic analysis of the research designs of these studies points at three major weaknesses. First, only short-term outcomes are measured, most often within six months after the conclusion of the intervention, and even within such a narrow time window, we find indications that treatment impacts fade out. A second limitation concerns the limited range of outcomes measured (receptive or expressive vocabulary). Finally these studies display low external validity (ad hoc sampling, small sample sizes, lack of multi-site experiments, scant evidence outside Anglo-saxon countries).
