The karst hydrological processes are the response of karst groundwater system to precipitation. The precipitation penetrates through the vadose zone, the subsequent groundwater pressure wave propagates to a spring outlet, and then, the spring discharge changes. This paper proposes a grey...

Sustainable groundwater development must rely on a good understanding of hydrological processes, especially under effects of anthropogenic activities. This paper develops a piecewise analysis based on grey system model for study effects of anthropogenic activities on hydrological processes. The...

This study establishes a multi-tier framework to evaluate how fund manager characteristics systematically affect mutual fund performance. The framework includes three tiers of performance elements: 1) comprehensive performance, 2) return and risk, and 3) timing skill and picking ability. Using...
