Análisis de conocimientos sobre aulas de comunicación y lenguaje de futuros/as maestros/as.
2021
Resumen basado en el de la publicación Título, resumen y palabras clave en español y en inglés Uno de los recursos regulados para la adecuada inclusión de alumnado con necesidades específicas de apoyo educativo (NEAE) en centros educativos ordinarios en la Comunidad Valenciana son las aulas de comunicación y lenguaje (CyL). El éxito de este recurso depende, entre otros aspectos, de los conocimientos que tenga el profesorado tanto generalista como especialista sobre su funcionamiento. Se analizan los conocimientos, los errores y las lagunas de los estudiantes de último curso de los grados de Maestro/a en Educación Infantil y de Maestro/a en Educación Primaria sobre el funcionamiento de estas…
Ecological Complex Systems
2008
Main aim of this topical issue is to report recent advances in noisy nonequilibrium processes useful to describe the dynamics of ecological systems and to address the mechanisms of spatio-temporal pattern formation in ecology both from the experimental and theoretical points of view. This is in order to understand the dynamical behaviour of ecological complex systems through the interplay between nonlinearity, noise, random and periodic environmental interactions. Discovering the microscopic rules and the local interactions which lead to the emergence of specific global patterns or global dynamical behaviour and the noises role in the nonlinear dynamics is an important, key aspect to unders…
Why do financial inclusion policies fail in mobilizing savings from the poor ? Lessons from rural south India
2017
© The Authors 2017. Development Policy Review © 2017 Overseas Development Institute Combining multivariate and qualitative analyses, this micro-level study suggests an explanation for the persistence of informal savings in rural south India despite publicly run large-scale programmes to promote bank savings. Gold, in particular, but also Rotating Saving and Credit Associations (ROSCAs) and private lending, remain the dominant forms of savings. We argue that cultural norms and social institutions, such as social class and caste, shape the nature of savings, and also the propensity and opportunities to save. Gold serves multiple purposes, financial, economic, socio-cultural and political. Fur…
Networked relationships in the e-MID Interbank market: A trading model with memory
2014
Interbank markets are fundamental for bank liquidity management. In this paper, we introduce a model of interbank trading with memory. Our model reproduces features of preferential trading patterns in the e-MID market recently empirically observed through the method of statistically validated networks. The memory mechanism is used to introduce a proxy of trust in the model. The key idea is that a lender, having lent many times to a borrower in the past, is more likely to lend to that borrower again in the future than to other borrowers, with which the lender has never (or has in- frequently) interacted. The core of the model depends on only one parameter representing the initial attractiven…
Do firms share the same functional form of their growth rate distribution? A statistical test
2014
We introduce a new statistical test of the hypothesis that a balanced panel of firms have the same growth rate distribution or, more generally, that they share the same functional form of growth rate distribution. We applied the test to European Union and US publicly quoted manufacturing firms data, considering functional forms belonging to the Subbotin family of distributions. While our hypotheses are rejected for the vast majority of sets at the sector level, we cannot rejected them at the subsector level, indicating that homogenous panels of firms could be described by a common functional form of growth rate distribution.
The effect of round-off error on long memory processes
2011
We study how the round-off (or discretization) error changes the statistical properties of a Gaussian long memory process. We show that the autocovariance and the spectral density of the discretized process are asymptotically rescaled by a factor smaller than one, and we compute exactly this scaling factor. Consequently, we find that the discretized process is also long memory with the same Hurst exponent as the original process. We consider the properties of two estimators of the Hurst exponent, namely the local Whittle (LW) estimator and the Detrended Fluctuation Analysis (DFA). By using analytical considerations and numerical simulations we show that, in presence of round-off error, both…
Urban segregation and unemployment: A case study of the urban area of Marseille – Aix-en-Provence (France)
2018
International audience; In this paper, we study the effects of the spatial organization of the urban area of Marseille – Aix-en-Provence on unemployment there. More specifically, differences in the characteristics of the residential population induce urban stratification with the result that urban structure may affect the probability of employment. In order to evaluate the effects of spatial structure on unemployment, we implement a spatial probit model to reveal the employment probabilities of young adults still living with their parents. Our results support the hypothesis that living in or near a deprived neighborhood decreases the probability of employment.
RENT CREATION AND RENT SHARING: NEW MEASURES AND IMPACTS ON TOTAL FACTOR PRODUCTIVITY
2019
International audience; This analysis proposes new measures of rent creation and rent sharing and assesses their impact on productivity on cross-country-industry panel data. We find first that: (1) anticompetitive product market regulations positively affect rent creation and (2) employment protection legislation boosts hourly wages, particularly for low-skill workers. However, we find no significant impact of this employment legislation on rent sharing, as the hourly wage increases are offset by a negative impact on hours worked. Second, using regulation indicators as instruments, we find that rent creation and rent sharing both have a substantial negative impact on total factor productivi…
The asset reallocation channel of quantitative easing. The case of the UK
2022
We investigate the impact of the Bank of England's asset purchase program (APP) on the composition of assets of UK banks with unique data on the received reserves injections. The Monetary Policy Committee (MPC) didn't expect there to be strong transmission of the APP's impact through the bank lending channel. We find that compared to the control group, treated banks reallocated their assets towards lower risk-weighted investments, such as government se-curities, but did not provide more credit to the real economy. Overall, our findings suggest that when banks are not adequately capitalised, risk-based capital constraints can limit the effec-tiveness of expansionary unconventional monetary p…
Determinants of success of donation-based crowdfunding through digital platforms : The influence of offline factors
2019
The purpose of this research consist of exploring the extent to which factors traditionally explaining the success of offline fundraising campaigns for social causes may also influence the success of donationbased crowdfunding (DCF) campaigns promoted by social economy organizations (SEO) through digital platforms. Firstly, factors determining the success of offline fundraising campaigns for social causes are identified from previous literature. Secondly, a set of hypotheses linking these determinants to DCF campaigns is proposed. Thirdly, their explanatory capacity is measured through quantitative analysis based on a database of 360 campaigns fostered by small, medium and large-size organi…
