What Explains Racial Differences in Farm Succession Planning? Evidence From Decomposition and Counterfactual Analysis

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper examines racial differences in farm succession planning using survey data from Tennessee farmers. While observed differences between White and Black farmers are small, decomposition and counterfactual analyses show that structural characteristics, particularly farm size, would predict higher succession planning among White farmers ...

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

The Tikhonov Regularization Method for Set-Valued Variational Inequalities

open access: yesAbstract and Applied Analysis, 2012
This paper aims to establish the Tikhonov regularization theory for set-valued variational inequalities. For this purpose, we firstly prove a very general existence result for set-valued variational inequalities, provided that the mapping involved has ...

Economic Impact of Sustainability in Wine Sector: A Systematic Literature Review

open access: yesAgribusiness, EarlyView.
ABSTRACT Sustainability has become a key issue in the wine sector, raising questions about its compatibility with firms' economic performance. Despite growing attention to environmental and social practices, evidence on their economic implications remains fragmented.

Global Bounds for Cocoercive Variational Inequalities

open access: yesAbstract and Applied Analysis, 2007
By using the strong monotonicity of the perturbed fixed-point map and the normal map associated with cocoercive variational inequalities, we establish two new global bounds measuring the distance between any point and the solution set for cocoercive ...

A Cable‐Driven Parallel Wire Robot for Probe Positioning and Tissue Palpation on Curved Phantoms

open access: yesAdvanced Intelligent Systems, EarlyView.
A wearable cable‐driven parallel robot is introduced for autonomous ultrasound probe positioning and soft tissue palpation on curved surfaces. By combining visual feedback with tension‐optimized control, the system achieves millimeter‐scale positioning accuracy while enforcing safety force constraints.

AI‐Enabled RGB Light‐to‐Frequency Sensor for Nondestructive Salinity Stress Monitoring in Medicinal Plants

open access: yesAdvanced Intelligent Systems, EarlyView.
A distributed wireless sensing framework enables noninvasive monitoring of plant salinity stress through leaf reflectance measurements acquired with portable optical sensors. The collected data are processed using TinyML‐based neural network models deployed at the edge, enabling accurate, real‐time, and low‐cost classification of salinity levels, while

Regularization of Brezis pseudomonotone variational inequalities

open access: yes, 2020
In this paper we prove the existence of solutions of regularized set-valued variational inequalities involving Br ́ezis pseudomonotone operators in reflexive and locally uniformly convex Banach spaces. By taking advantage of this result, we approximate

Directional differentiability for elliptic quasi-variational inequalities of obstacle type [PDF]

open access: yes, 2018
The directional differentiability of the solution map of obstacle type quasi-variational inequalities (QVIs) with respect to perturbations on the forcing term is studied. The classical result of Mignot is then extended to the quasi-variational case under
