Patch management is a crucial component of information security management. An important problem within this context from a vendor's perspective is to determine how to release patches to fix vulnerabilities in its software. From a firm's perspective, the issue is how to update vulnerable systems...

Proper configuration of security technologies is critical to balance the access and protection requirements of information. The common practice of using a layered security architecture that has multiple technologies amplifies the need for proper configuration because the configuration decision...

Depression is a serious mental disorder which affects more than 350 million people of all ages worldwide in the 2012 and physical activity is generally believed to be effective in combating depressive symptoms. This study investigates the effects of regular physical activity and sociodemographic...

This work presents an efficient methodology for the Reliability Based Design Optimization (RBDO) of the tripod sub-structure of offshore wind turbines considering dynamic response requirements. The cost of supporting structure of offshore wind turbines is so high that optimization in the design...

How much do the market values of housing reflect its interior design? Does the interior design interact with other housing attributes? Following the recent research based on “graph theory,” this paper confirms the importance of internal design variables in a hedonic pricing model, which is...

Will generous return policies in auctions benefit bidders? We investigate this issue using second-price common-value auctions. Theoretically, we find that the bidding equilibrium is unique unless returns are free, in which case there exist multiple equilibria with different implications for...

This paper focuses on designing a hybrid generation bioethanol supply chain (HGBSC) that will account for economic, environmental and social aspects of sustainability under various uncertainties. A stochastic mixed integer linear programming model is proposed to design an optimal HGBSC. A case...

This note extends some of the key results of Dong and Rudi (2004) to general demand distributions. This generalization is achieved in two steps. First, we build on the analysis of Dong and Rudi to demonstrate that an inventory problem with transshipment is equivalent to a newsvendor problem with...
