Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Study on failure characteristics of coal sample under different unloading stress paths

open access: yesGong-kuang zidonghua, 2022
The existing research on the failure characteristics of coal samples has some problems, such as single mechanical parameter test and large limitation of stress loading direction.

Rock burst risk evaluation based on equivalent surrounding rock strength

open access: yesInternational Journal of Mining Science and Technology, 2019
On-site investigations consistently show that the rock burst inherent to coal seams varies greatly with coal seam thickness. In this study, impact factors related to coal seam thickness and surrounding rock strength were analyzed and a corresponding rock

‘Where are the adults?’: Troubling child‐activism and children's political participation

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Erwin Schrödinger und die Versuchungen der (Wissenschafts‐)Biografik: Vorurteilsgefüge und Mechanismen der Skandalisierung

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Experimental study on the overburden movement and stress evolution in multi‐seam mining with residual pillars

open access: yesEnergy Science & Engineering, 2019
When faced with multi‐seam mining, some coal pillars are left to support the overlying strata when mining the lower seam, where stress concentration usually occurs.

A Study on the Failure Characteristics of Coal–Rock Structures with Different Bursting Liabilities

open access: yesProcesses
Research on the deformation and failure behavior of coal is a key scientific issue in the study of coal–rock dynamic disaster prevention technology. It is a critical means to grasp the structural effect of coal–rock deformation and failure behavior to explore the effects of fracture structure on coal–rock deformation and failure behavior.

Carbon Footprint of Bank Loans: Opportunities and Risk Implications in the Banking Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether the carbon footprint of bank loan portfolios influences bank stability, profitability and cost efficiency and whether regulatory quality moderates these relationships. Using a balanced panel of 33 countries from 2005 to 2018, the analysis combines banking‐sector indicators from the World Bank Global Financial ...
