Does Productivity Growth Promote Environmental Sustainability? The Role of Financial Development
Sustainable Development, EarlyView.ABSTRACT This study investigates whether total factor productivity (TFP) promotes environmental sustainability and examines the moderating and mediating roles of financial development in shaping this relationship. Using balanced panel data for 92 countries from 2000 to 2023, the analysis employs dynamic two‐step Generalised Method of Moments (GMM ...

Shaping expectations, losing flexibility: A study of CEO promises as strategic communication tools
Strategic Management Journal, EarlyView.Abstract Research Summary CEO promises are powerful but understudied communication tools. We develop a dual‐mechanism framework theorizing that while CEO promises elevate stakeholder expectations, they simultaneously constrain strategic flexibility. We argue that CEO promise‐making is shaped by two competing pressures: making more promises when the ...

Small, EarlyView.An N, Sv‐ZnIn2S4/1T‐2H WS2 composite photocatalyst is constructed via an in situ hydrothermal‐solvothermal strategy, simultaneously forming a defect‐induced p‐n homojunction in ZnIn2S4 and a type‐II heterojunction with hybrid 1T/2H WS2. The coupled dual built‐in electric fields promote charge separation and direct photoexcited electrons toward sulfur ...

A Dyna_Q-learning Algorithm Used in Underground Path Planning
Gong-kuang zidonghua, 2012 The Euclidean distance is usually used in heuristic planning of Dyna_Q-learning based on reinforcement learning tasks of goal position. But it is not suitable for these tasks whose state space is not continuous in Euclidean space such as path planning of
