Heterogeneous Effects of Farm and Nonfarm Income on Household Consumption Expenditure and Inequality

Review of Development Economics, EarlyView.
ABSTRACT This study examines the heterogeneous effects of farm income and nonfarm income on household consumption expenditure and consumption expenditure inequality, using data from the 2016 China Labor Force Dynamics Survey. A two‐stage residual inclusion model is employed to address the endogeneity of nonfarm income.

How Input Subsidies Boost Food Security in Developing Countries: Micro‐Level Evidence From Zambia

Review of Development Economics, EarlyView.
ABSTRACT While previous studies have examined the effects of input subsidies on income and yields, we study their impact on food security, measured through household dietary diversity, a key dimension of nutritional well‐being—examined across specific pathways.

Large block coal detection algorithm for fully mechanized working face based on MES-YOLOv5s

Gong-kuang zidonghua
The objects in the fully mechanized working face have the features of high-speed motion, multi-scale, occlusion, etc. The existing object detection algorithms have problems such as low precision, large memory of models, and strong hardware dependence. In order to solve the above problems, a large block coal detection algorithm based on MES-YOLOv5s is ...

Heidegger and Levinas on the phenomenology of the hand: Between work and gesture

The Southern Journal of Philosophy, EarlyView.
Abstract This article explores how Heidegger and Levinas develop distinct phenomenological accounts of the hand. Both thinkers refuse to treat the hand as merely an anatomical organ, instead viewing it as an essential dimension of human existence. Yet their interpretations diverge sharply. In the first section, I show how Heidegger grounds the function
