GROSS INLAND ENERGY CONSUMPTION INEQUALITY IN EUROPE: AN EMPIRICAL APPROACH

Revista de Economía Mundial, 2018
This paper analyses the gross inland energy consumption (EC) in the European Union countries (EU-15) over the period 2005-2014. The standard tools in the measurement of income inequality such as Lorenz curves, Gini index, Generalized Entropy indices and ...

Tsallis Log-Scale-Location Models. Moments, Gini Index and Some Stochastic Orders

Mathematics, 2021
In this article we give theoretical results for different stochastic orders of a log-scale-location family which uses Tsallis statistics functions. These results describe the inequalities of moments or Gini index according to parameters.

Lorenz Curves, Size Classification, and Dimensions of Bubble Size Distributions

Entropy, 2009
Lorenz curves of bubble size distributions and their Gini coefficients characterize demixing processes. Through a systematic size classification, bubble size histograms are generated and investigated concerning their statistical entropy.

Inequalities in out-of-pocket health expenditure among women of reproductive age: after-effects of national health insurance scheme initiation in Ghana

Journal of the Egyptian Public Health Association, 2021
Background Improvement in maternal healthcare is a public health priority. Unfortunately, in spite of the efforts made over time regarding universal coverage, there remain issues with accessibility and use of healthcare services up to now. In this study,

An Exponential Family of Lorenz Curves [PDF]

Southern Economic Journal, 2001
A new method for building parametric‐functional families of Lorenz curves, generated from an initial Lorenz curve (which satisfies some regularity conditions), is presented. The method is applied to the exponential family since they use the exponential Lorenz curves as their generating curves.

Estimating Lorenz and Concentration Curves [PDF]

The Stata Journal: Promoting communications on statistics and Stata, 2016
Lorenz and concentration curves are widely used tools in inequality research. In this article, I present a new command, lorenz, that estimates Lorenz and concentration curves from individual-level data and, optionally, displays the results in a graph.

Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

Advanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Comparison of five equations in describing the variation of leaf area distributions of Alangium chinense (Lour.) Harms

Frontiers in Plant Science
Previous studies have validated a performance equation (PE) and its generalized version (GPE) in describing the rotated and right-shifted Lorenz curves of organ size (e.g., leaf area and fruit volume) distributions of herbaceous plants.

Paracrine Factor Local Gradient‐Generating System for Engineering Perfusable Vascularized Hepatocyte Tissues with Perfusion‐Induced Proliferation

Advanced Healthcare Materials, EarlyView.
A paracrine factor local gradient (PFLG)‐generating system enables microvessel penetration across 3D hepatocyte tissues. The resulting vascularized constructs recapitulate hepatic sinusoidal hepatocyte—endothelial contact architecture and enhance hepatic functions in vitro.
