The Effect of Migration on Income Growth and Convergence: Meta-Analytic Evidence We compare a set of econometric studies that measure the effect of net internal migration in neoclassical models of long-run real income convergence and derive 67 comparable effect sizes. The precision-weighted estimate of beta convergence is about 2.7%. An increase in the net migration rate of a region by one perc...

In this paper analytical study has been made to investigate a hybrid refrigerant consists of different refrigerants with mixing ratios and find out its effects on the performance cycle specify best that gives least environmental pollution. Firstly vapor compression refrigeration system analyzed several pure refrigerants( R11, R12, R13,R22,R23, R32, R41, R115, R116, R124, R125, R134a, R142a, R14...

recently, economists have attention to the brain drain as emigration of skilled and educated labor force from developing countries. in this case, we are dealing with one main question is: how brain drain can affect the human capital of source countries? based on existing theories, brain drain can affect the economy of source countries in different ways such as; direct reduction of human capital...

À partir des données issues du recensement général de la population 2014, nous analysons à l’échelle bassins vie, le lien entre migration résidentielle destination espaces ruraux et périurbains ségrégation socio-spatiale. Nos résultats montrent que les individus sont sensibles aux caractéristiques sociodémographiques voisina...

We define a new class of unitary solutions to the classical Yang-Baxter equation (CYBE). These “boundary solutions” are those which lie in the closure of the space of unitary solutions to the modified classical Yang-Baxter equation (MCYBE). Using the Belavin-Drinfel’d classification of the solutions to the MCYBE, we are able to exhibit new families of solutions to the CYBE. In particular, using...

We introduce super Yangian double DYh̄[gl(m|n)] and its central extension ̂ DYh̄[gl(m|n)]. We give their defining relations in terms of current generators and obtain Drinfeld comultiplication. Queen Elizabeth II Fellow; Email: yzz@maths.uq.edu.au This paper concerns with Drinfeld current realization [1] of super Yangian double DYh̄[gl(m|n)] and its central extension ̂ DYh̄[gl(m|n)]. The Yangian doubl...

ABSTRACT Strong line metallicity calibrations are widely used to determine the gas phase metallicities of individual H ii regions and entire galaxies. Over a decade ago, based on Sloan Digital Sky Survey Data Release 4, Kewley & Ellison published coefficients third-order polynomials that can be convert between different strong for global galaxy spectra. Here, we update work in three ways. F...

En Belgique, nombreux sont ceux qui ont été confrontés au télétravail intensif suite à la crise de Covid-19. À partir l’analyse données individuelles l’Enquête sur les Forces Travail, notre recherche s’est attachée approfondir connaissances propension avant cette crise, en Belgique et Bruxelles. Pour ce faire, nous avons é...
