Tremendous effort has been spent on the construction of reliable efficient frontiers. However, mean-variance efficient portfolios constructed using sample means and covariance often perform poorly out of sample. We prove that, the capital market line is the efficient frontier for the risky...

Whereas the technical feasibility of solar water heaters (SWHs) has long been established, the economic feasibility of SWHs in regional China remains to be examined. This paper constructs cost models to calculate costs per unit energy saving of SWHs in 27 Chinese provincial capital cities. The...

This paper attempts to explore key determinants of competitiveness in the textile and apparel industries, with special reference to Chinese Mainland. The authors conduct a survey that is designed to use productivity, supply-side and demand-side determinants to measure enterprises'...

Purpose The purpose of this paper is to design a multi-sensory anthropomorphic prosthetic hand and a grasping controller that can detect the slip and automatically adjust the grasping force to prevent the slip. Design/methodology/approach To improve the dexterity, sensing, controllability and...

Purpose – The paper seeks to develop an analytical theory of project investment. Design/methodology/approach – The authors derive a partial differential equation that the variable cost of a project should satisfy, determine a proper initial condition through a thought experiment, and solve...

Purpose – Contracting is an important issue in supply chain management. In this paper, the authors aim to discuss and compare the manufacturer's contracting options when the retailer faces a traditional newsvendor problem with a fixed retail price: a wholesale price only contract, a wholesale...

Over recent decades, China has risen to a preeminent global position in both solar photovoltaic (PV) adoption and production, a feat underpinned by a suite of pivotal policy measures. With a burgeoning demand for PV systems on the horizon, there is an urgent need to reassess past policies and...

Purpose The purpose of this paper is to examine the impacts of future climate change and the corresponding adaptation activities on grain production and its regional distribution in China. Design/methodology/approach This paper applied the Chinese Agricultural Policy Analysis model, in...
