Photocatalytic degradation is a promising means to restore the ever-growing pharmacological active compounds (PHACs) contamination in the water environment. Herein, the oxygen vacancies (OVs) modulated Z-scheme CuWO4/CuBi2O4 hybrid systems were fabricated at thermal treatment by in-situ loading...

Ridesharing has become popular over the last decade, bringing significant changes to residents’ travel patterns and city traffic. Relevant to the growth and impact of ridesharing activities in populous urban areas are the side effects, such as air pollution and traffic congestion. Despite a...

We investigate the joint effects of analyst reputation, uncertainty, and guidance news valence on analysts’ reliance on management guidance. We find that, compared to less reputable analysts, reputable analysts rely less on guidance when they issue earnings forecasts. This analyst reputation...

We construct two operational systems of a perishable firm, the traditional and quick-response systems, selling to strategic consumers with regrets or without regrets over two periods. When strategic consumers buy the product at the full-price period, they may experience high-price regret....

We propose a new set of stylized facts quantifying the structure of financial markets. The key idea is to study the combined structure of both investment strategies and prices in order to open a qualitatively new level of understanding of financial and economic markets. We study the detailed...

Using a sample of 1486 Chinese A-share listed companies for the period 2004–2008, this study empirically tests the impact of family control, institutional environment and their interaction on the cash dividend policy of listed companies. Our results indicate that (1) family firms have a lower...

We study fixed-dimensional stochastic dynamic programs in a discrete setting over a finite horizon. Under the primary assumption that the cost-to-go functions are discrete L♮-convex, we propose a pseudo-polynomial time approximation scheme that solves this problem to within an arbitrary...

We study several dynamic, stochastic inventory control models with integer demands: the newsvendor model, its multi-period extension and a single-product, multi-echelon assembly model. Equivalent linear programs are formulated for the corresponding stochastic dynamic programs, and integrality...
