International R&D spillovers in the multi-country Schumpeterian growth model

2007

en ligne : http://ungaro.u-bourgogne.fr/pages/Documents%20de%20travail/Economie/e2007-04.pdf; Document de travail du LEG 2007-04; This paper reconsiders the multi-country Schumpeterian growth model and its empirical implications. We first show that the model implies a spatial econometric reduced form. Indeed, the global interdependence implied by international R&D spillovers needs to betaken into account in the theoretical model as well as in the empirical model. The spatial econometric model we propose includes the neoclassical growth model as a particular case. We can therefore test explicitly the role of R&D investment in the long run growth processagainst the Solow growth model which is…

An Emulator Toolbox to Approximate Radiative Transfer Models with Statistical Learning

2015

Physically-based radiative transfer models (RTMs) help in understanding the processes occurring on the Earth’s surface and their interactions with vegetation and atmosphere. When it comes to studying vegetation properties, RTMs allows us to study light interception by plant canopies and are used in the retrieval of biophysical variables through model inversion. However, advanced RTMs can take a long computational time, which makes them unfeasible in many real applications. To overcome this problem, it has been proposed to substitute RTMs through so-called emulators. Emulators are statistical models that approximate the functioning of RTMs. Emulators are advantageous in real practice because…

Représentation, analyse et caractérisation de surfaces rugueuses

2020

Nous présentons un projet de recherche dans lequel, nous proposons d’aborder la problématique de la représentation numérique, de l’analyse et de la caractérisation de surfaces rugueuses. La rugosité est un concept complexe, par nature multi-échelle et reposant sur l’étude du comportement local d’une surface dans un voisinage donné. Son évaluation sur les surfaces est essentielle pour de nombreux problèmes expérimentaux. Cela explique les nombreuses études réalisées dans les domaines applicatifs liés à la physique et la mécanique, là où le contrôle et la maîtrise de l’état des surfaces constituent un besoin majeur pour les industriels. Un grand nombre de paramètres conventionnels normalisés …

Multicriteria Decision Aiding for Planning Renewable Power Production at Moroccan Airports

2022

This study is about multicriteria decision aiding (MCDA) for the green airports program of the Moroccan Airport Authority ONDA. The goal of the program is to develop significant amounts of renewable power at airports. In particular, ONDA wants to select airports at which large solar and wind power parks should be built. Multiple criteria, including economy, technical feasibility, and environmental concerns, must be considered simultaneously. In this study, we apply Stochastic Multicriteria Acceptability Analysis (SMAA) for ranking the candidates to be developed into green airports. The analysis is conducted in phases with different sets of criteria. This study is the first application of MC…

Valutazione multicriteriale del saggio di capitalizzazione per la revisione del catasto degli immobili urbani - Capitalization rate multidimensional …

2013

The new revision of the land register is intended to give each real estate unit an assessed value which approximates the market value. The provided approach has statistical nature. However, in the absence of a well-established market, the coming reform requires the use of the indirect estimation procedure.This paper proposes a method for estimating the capitalization rate that could usefully be applied in mass appraisal. The proposed model for the evaluation of the capitalization rate is intended as an alternative to traditional inferential processes that apply in real estate market. It can be used even in market segments that are not enough active and does not require the use of technical …

Multilevel Latent Profile Analysis With Covariates : Identifying Job Characteristics Profiles in Hierarchical Data as an Example

2018

Latent profile analysis (LPA) is a person-centered method commonly used in organizational research to identify homogeneous subpopulations of employees within a heterogeneous population. However, in the case of nested data structures, such as employees nested in work departments, multilevel techniques are needed. Multilevel LPA (MLPA) enables adequate modeling of subpopulations in hierarchical data sets. MLPA enables investigation of variability in the proportions of Level 1 profiles across Level 2 units, and of Level 2 latent classes based on the proportions of Level 1 latent profiles and Level 1 ratings, and the extent to which covariates drawn from the different hierarchical levels of th…

The competency-based approach in developing countries

2013

For decades, all analyzes converge on the idea of the relative inefficiency of education systems in sub-Saharan Africa. Dropout, repetition, overstaffing, low quality of learning student failure and obsolescence of facilities, teaching materials and teachers, including sometimes the levels and quality of education remain somewhat uncertain, inadequate educational programs. In short, these are some of the ills that plague these systems and confirm the findings made by many reports.Given this weakness finding, educational authorities, supported by international aid mobilized in many countries to improve their systems to qualitatively, but also quantitatively equity because we must not forget …
