The Role of Certifications in Improving Household Food Security Among Peruvian Farmers
Agribusiness, EarlyView.ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.

Theil, Inequality Indices and Decomposition [PDF]
Theil’s approach to the measurement of inequality is set in the context of subsequent developments over recent decades. It is shown that Theil’s initial insight leads naturally to a very general class of decomposable inequality measures.

Groundings, 2015 The Gini coefficient, one of the most widely used inequality measures in economics, is thought to report income disparity with a reliable degree of objectivity. However, a critical assessment of the Gini’s implicit normative assumptions reveals that this

Indicators of Inequality and Poverty [PDF]
This essay aims at a broad, main-stream account of the literature on inequality and poverty measurement in the space of income and, additionally, deals with measures of disparity and deprivation in the more expanded domain of capabilities and ...

A multiscale Bayesian optimization framework for process and material codesign
AIChE Journal, EarlyView.Abstract The simultaneous design of processes and enabling materials such as solvents, catalysts, and adsorbents is challenging because molecular‐ and process‐level decisions are strongly interdependent. Sequential approaches often yield suboptimal results since improvements in material properties may not translate into superior process performance. We

Trust‐region filter algorithms utilizing Hessian information for gray‐box optimization
AIChE Journal, EarlyView.Abstract Optimizing industrial processes often involves gray‐box models that couple algebraic glass‐box equations with black‐box components lacking analytic derivatives. Such systems challenge derivative‐based solvers. The classical trust‐region filter (TRF) algorithm provides a robust framework but requires extensive parameter tuning and numerous ...

Desigualdade entre estados na distribuição da renda no Brasil
Economia Aplicada, 1997 Using data on income distribution among economically active persons it is shown that from 1970 to 1980 there was a substantial decrease in the interstate inequality in Brazil, ratifying results obtained from data on per capita product of the states ...

A trust‐region funnel algorithm for gray‐box optimization
AIChE Journal, EarlyView.Abstract Gray‐box optimization, where parts of optimization problems are represented by algebraic models while others are treated as black‐box models lacking analytic derivatives, remains a challenge. Trust‐region (TR) methods provide a robust framework for gray‐box problems through local reduced models (RMs) for black‐box components, but they are ...
