Using large samples of estate tax returns, we construct new series on wealth concentration in Paris and France from 1807 to 1994. Inequality increased until 1914 because industrial and financial estates grew dramatically. Then, adverse shocks, rather than a Kuznets-type process, led to a massive decline in inequality. The very high wealth concentration prior to 1914 benefited retired individual...
Two approaches to improve the convergence of the multipole series were considered 1) an increase in the order of the expansion; 2) decomposition of the molecular charge density into smaller distributions. New decompositions of the molecular electronic density and a computational procedure to generate high-order moments are presented. The accuracy and timing of test calculations on the H2O ... H...
The aim of the present study was to develop and validate the Children's Depression Screener (ChilD-S) for use in pediatric care. In two pediatric samples, children aged 9-12 (N(I) = 200; N(II) = 246) completed an explorative item pool (subsample I) and a revised item pool (subsample II). Diagnostic accuracy of each of the 22 items from the revised pool was evaluated in order to select the best ...
This paper examines the implications of tax evasion for "scal competition and tax harmonization policies in an economic union. First, for symmetric countries, it proves that the equilibrium values of the tax and audit rates are less than optimal. Tax harmonization alone will also lead to a less than optimal audit rate. Second, for asymmetric countries, the paper shows that integration may turn ...

Previous research studies have demonstrated that the relationship between remote sensing-derived parameters and aboveground biomass (AGB) could vary across different species types. However, there are few studies that calibrate reliable statistical models for mangrove AGB. This study quantifies the differences of accuracy in AGB estimation between the results obtained with and without the consid...
هدف این کار به دست آوردن خواص ترمودینامیکی و اثر آمینواسیدهای آلانین و گلیسین بر روی محلول های آبی پلیمری است. در بخش اول این کار، داده های تجربی فعالیت آب در دمای 15/298 کلوین برای سیستم ¬های سه-تایی (alanine + ppg400 + h2o)، (alanine + peg400 + h2o)، (alanine + peg2000 + h2o)، (alanine + peg10000 + h2o)، ((glycine + ppg400 + h2o، (glycine + peg400 + h2o)، (glycine + peg2000 + h2o) و (glycine ...
