On August 7 and 8, 2010, a catastrophic debris flow disaster occurred in Zhouqu County in northwestern China’s Gansu Province. The large-scale debris flow event destroyed more than 200 buildings, killing approximately 1,700 people. Field investigations showed that the debris flow disaster was...

During the process of urbanization and industrialization, groundwater has been extensively overexploited, with the direct result of continuously decreasing groundwater level, followed by the appearance of large scale of depression cones, which is furthermore followed by land subsidence, seawater...

In this paper, a full-Newton step feasible interior-point algorithm is proposed for solving <InlineEquation ID="IEq3"> <EquationSource Format="TEX">$$P_*(\kappa )$$</EquationSource> <EquationSource Format="MATHML"> <math xmlns:xlink="http://www.w3.org/1999/xlink"> <mrow> <msub> <mi>P</mi> <mo>∗</mo> </msub> <mrow> <mo stretchy="false">(</mo> <mi mathvariant="italic">κ</mi> <mo stretchy="false">)</mo> </mrow> </mrow> </math> </EquationSource> </InlineEquation>-linear complementarity problems. We prove that the full-Newton step to the central path is local quadratically convergent and the proposed algorithm has...</equationsource></equationsource></inlineequation>

Nonlocal effects on the energy conversion efficiency of the second-harmonic generation (SHG) for a p-polarized incident field in a Pöschl-Teller quantum well (PTQW) are investigated in detail. The numerical results show that the spatial distribution of the second-harmonic field is nonuniform,...

We study the risk-averse newsvendor model with a mean-variance objective function. We show that stockout cost has a significant impact on the newsvendor's optimal ordering decisions. In particular, with stockout cost, the risk-averse newsvendor does not necessarily order less than the...

The digital technologies that have made electronic commerce (EC) a reality have changed the landscape of operations management (OM). Past OM studies have focused on the relationship between information systems (IS) and OM strategy, however, there is a lack of investigation into the environmental...

This study investigates whether brand name has an impact on personal customers’ adoption of Internet banking (IB) in Hong Kong. Based on the Technology Acceptance Model (TAM) with proper adaptation to the online environment, we propose a model comprising an external factor, namely brand...

We consider a supply chain comprising a manufacturer and a retailer. The manufacturer supplies a product to the retailer, while the retailer sells the product bundled with after-sales service to consumers in a fully competitive market. The sales volume is affected by the retailer’s...

Many scholars and service practitioners perceive service recovery as an important means to retain customer after service failures, but in practice many service recovery efforts are unsuccessful. Studies on service recovery suggest that recovery activities are the core process of service...
