Realistic Representation, Dynamic Evolution and Determinants of Institutional Quality in China

International Studies of Economics, EarlyView.
ABSTRACT The paper delves into the role of institutional quality in bolstering China's economic resilience post‐COVID‐19, CITIC‐Entropy. It divides institutions into basic and changeable categories, establishing an index system via the CITIC‐Entropy TOPSIS model.

A Tale of Two Transitions: Mobility Dynamics in China and Russia After Central Planning

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper examines intergenerational mobility in China and Russia during their transitions from central planning to market systems. We consider mobility as movement, measured as changes in status between parents and children. We provide estimates of two key mobility measures: overall mobility, which captures total intergenerational movement ...

Semi-Markov decision problems and performance sensitivity analysis

, 2003
Recent research indicates that Markov decision processes (MDPs) can be viewed from a sensitivity point of view; and perturbation analysis (PA), MDPs, and reinforcement learning (RL) are three closely related areas in optimization of discrete-event ...

Mono-unireducible non-homogeneous semi-Markov processes applied to rating migration models [PDF]

, 2012
Monounireducible nonhomogeneous semi- Markov processes are defined and investigated. The mono- unireducible topological structure is a sufficient condition that guarantees the absorption of the semi-Markov process in a state of the process.

The Relationship Between Human Activities and Ecosystem Service Supply–Demand From the Perspective of Land Use Transformation

Land Degradation &Development, EarlyView.
ABSTRACT The equilibrium between ecosystem service supply and demand relationships (ESSDR) is essential for regional sustainable development. Understanding the relationship between human activity intensity (HAI) and ESSDR from the perspective of land use transformation (LT) is important for ecological management and governance.

Unraveling the Spatiotemporal Dynamics and Nonlinear Drivers of Green Transition of Farmland Use in Major Grain‐Producing Areas: A Case Study of Jiangsu Province, China

Land Degradation &Development, EarlyView.
ABSTRACT Promoting the green transition of farmland use (GTFU) in major grain‐producing areas is essential for ensuring food security and advancing sustainable agricultural development. However, existing studies on GTFU have predominantly relied on static cross‐sectional analyses, with insufficient attention paid to its nonlinear driving mechanisms. To

Land Use Spatial Optimization Based on Multi‐Objective Ant Colony Algorithm and FLUS Model: A Case Study of Korla City and Tiemenguan City, China

Land Degradation &Development, EarlyView.
ABSTRACT In southern Xinjiang, China, scarce land and water resources and fragile ecosystems have intensified land use conflicts, making land resource allocation optimization essential for sustainable development in arid oasis areas. Focusing on Korla and Tiemenguan, this study aims to coordinate economic benefits, ecological benefits, and food ...

Future Soil Erosion Under Combined CMIP6 Climate Projections and Land Use/Land Cover Change: A RUSLE‐Based Assessment of the Kampe Omi Dam Basin in Nigeria

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major environmental challenge in Nigeria, driven by the combined effects of climate variability and land use/land cover (LULC) changes. Understanding future dynamics is essential for effective soil conservation planning.

Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

Mathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.
