Journal of International Development, EarlyView.ABSTRACT This study provides systematic review and meta‐analytical evidence on how parental migration affects children left behind. We reviewed 44 papers on education and child labour, plus 57 studies on remittances and aspirations. We find no meaningful average effect of parental migration on education or labour outcomes. However, after correcting for

Semi-analytical solutions of the nonlinear oscillator with a matrix Lagrange multiplier
Journal of Low Frequency Noise, Vibration and Active Control, 2019 In this paper, a semi-analytical method based on variational iteration formulae is proposed. Second-order nonlinear oscillator equations are numerically investigated by this method. A matrix Lagrange multiplier is given to derive analytical solutions and

Testing for Consistency using Artificial Regressions [PDF]
We consider several issues related to what Hausman (1978) called "specification tests", namely tests designed to verify the consistency of parameter estimates. We first review a number of results about these tests in linear regression models, and present

Land Degradation &Development, EarlyView.ABSTRACT Rainfall‐induced physical crusting is associated with degradation of near‐surface soil structure, but its pore‐scale structural and mechanical evolution during drying remains poorly resolved. We combined time‐resolved X‐ray computed tomography (XCT), digital volume correlation (DVC), and surface‐aligned stratification to track pore ...

Mathematical Methods in the Applied Sciences, EarlyView.A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Novel Approach for Dealing with Partial Differential Equations with Mixed Derivatives
Abstract and Applied Analysis, 2014 We propose a powerful iteration scheme for solving analytically a class of partial equations with mixed derivatives. Our approach is based upon the Lagrange multiplier in two-dimensional spaces. The local convergence and uniqueness of the proposed method

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT This paper focuses on optimal design problems in the context of the Kirchhoff‐Love model for pure bending of a thin, solid, symmetric plate under a transverse load. The objective is to simultaneously determine the optimal outer shape of the domain and the distribution of two isotropic materials within the domain in order to minimize compliance.
