Spatial effects and convergence theory in the Portuguese situation [PDF]
This study analyses, through cross-section estimation methods, the influence of spatial effects and human capital in the conditional productivity convergence (product per worker) in the economic sectors of NUTs III of mainland Portugal between 1995 and ...

EDUCATIONAL PERFORMANCE AND SPATIAL CONVERGENCE IN PERU [PDF]
While an enormous and growing literature exists on the topic of re-gional income convergence, other aspects of socioeconomic well-being and development have attracted much less attention. Social indicators are a valuable complement to economic indicators

Theoretical advances in two-step iterative schemes for nonlinear problems
Transactions on Computational Modeling and Intelligent SystemsThis study develops a two-step iterative method for solving nonlinear equations, focusing on its convergence properties. Using Taylor series expansion, the method assumes the nonlinear function is at least four times continuously differentiable with ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Fractional Output Convergence, with an Application to Nine Developed Countries [PDF]
We argue that cross-country convergence of output per capita should be examined in a fractional-integration time-series context and we propose a new empirical strategy to test it, which is the first one that discriminates between fractional long-run ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion
Advanced Engineering Materials, EarlyView.Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Local taxation in the EU: A convergence study
Investigaciones Regionales - Journal of Regional Research, 2019 In this note we study the convergence of local taxation in the EU-15 for 1975-2015 and two sub-periods, 1975-1994 and 1995-2015. Through a sigma convergence analysis, we find evidence of convergence for 1975-2015 and 1995-2015 but divergence for 1975-1994. In a club convergence approach, the countries are clustered into two clubs in the overall sample,
