摘要：Consumers are becoming more knowledgeable about companies' social responsibility (SR) practices. As a result, they are increasingly skeptical when companies do not provide clear information about these practices. One way to overcome this skepticism is to strengthen consumer trust through improved supply chain transparency. To create transparency requires a company to both gain visibility into its supply chain and disclose information to consumers. However, the current SR literature has only fo...

摘要：Many field office leaders contend that authoritarian leadership improves the performance of humanitarian operations. The common narrative is that authoritarian leadership helps aid workers more quickly adapt to changes and thus deliver better job performance (e.g., by improving operations in their field office). However, given that field reports often highlight extant leadership as the source of serious operational failures, could leaders with an authoritarian style be part of the problem? We ...

摘要：Prostate cancer (PCa) is common in American men with long latent periods, during which the disease is asymptomatic. Active surveillance is a monitoring strategy commonly used for patients diagnosed with low-risk PCa who may harbor latent high-risk PCa. The optimal monitoring strategy attempts to minimize the disutility of testing while ensuring that the patient is detected at the earliest time when the disease progresses. Unfortunately, guidelines for the active surveillance of PCa are often o...

摘要：Does the news media's reporting of the safety (or the lack thereof) of a firm's products impact managers' voluntary recalls of the products? The current article empirically answers this question in the context of safety defects in vehicles of 22 manufacturers from June 2009 to December 2020 in the United States. Results show that the volume of news reports about safety in a manufacturer's products increases voluntary recalls by managers. Further, the negativity in these news reports strengthen...

摘要：We study the problem of advance scheduling of ward admission requests in a public hospital, which affects the usage of critical resources such as operating theaters and hospital beds. Given the stochastic arrivals of patients and uncertain usage of resources, it is often infeasible for the planner to devise a risk-free schedule to meet these requests without violating resource capacity constraints and creating adverse effects that include healthcare overtime, long patient waiting times, and be...

摘要：In this paper, we discuss fleet size decisions of an equipment rental firm. The availability of the rental equipment depends on the fleet size of the firm and has a direct impact on its profitability. In our setting, we allow for partial backordering, reneging, and finite commitment capacity. Moreover, we explicitly consider the breakdown possibility of the available equipment fleet. We develop an efficient recursive algorithm to solve the underlying two-dimensional stochastic single-player mo...
