Dynamic Assignment of Flexible Service Resources

Resource flexibility is an important tool for firms to better match capacity with demand so as to increase revenues and improve service levels. However, in service contexts that require dynamically deciding whether to accept incoming jobs and what resource to assign to each accepted job, harnessing the benefits of flexibility requires using effective methods for making these operational decisions. Motivated by the resource deployment decisions facing a professional service firm in the workplace training industry, we address the dynamic job acceptance and resource assignment problem for systems with general resource flexibility structure, i.e., with multiple resource types that can each perform different overlapping subsets of job types. We first show that, for systems containing specialized resources for individual job types and a versatile resource type that can perform all job types, the exact policy uses a threshold rule. With more general flexibility structures, since the associated stochastic dynamic program is intractable, we develop and test three optimization‐based approximate policies. Our extensive computational tests show that one of the methods, which we call the Bottleneck Capacity Reservation policy, is remarkably effective in generating near‐optimal solutions over a wide range of problem scenarios. We also consider a model variant that requires dynamic job acceptance decisions but permits deferring resource assignment decisions until the end of the horizon. For this model, we discuss an adaptation of our approximate policy, establish the effectiveness of this policy, and assess the value of postponing assignment decisions.

Raising the Status of the Cashier: Latina–White Interactions in an Ethnic Market

Using a Latino-owned and -operated ethnic market in southern California as an ethnographic research site, we analyze and compare the interactions between foreign-born, Latina cashiers and their Latino and White customers. We ask two main questions: what is the nature of cashier–customer interactions, and what do they tell us about the social hierarchy in which they are embedded? While most studies of service interactions find that intraracial encounters are friendlier than interracial ones, the results of this study prove otherwise. We find that the Latina cashiers are routinely friendlier, more deferential, and extend the length of the interaction with their White customers. We conclude that Latina cashiers deliberately provide better service to their White customers because they feel that the patronage of White, middle-class shoppers raises their occupational status as well as the status of their workplace.

建国后30年浙江农村合作医疗制度的历史考察

从1950年代至1970年代,浙江农村合作医疗制度从萌芽、发展到兴盛经历了一个复杂的历史过程。浙江农村合作医疗制度是浙江农村合作化及人民公社化运动的衍生物,并相伴始终。此长彼长,此消彼消。考察这一段历史,有助于我们在理论及实践两方面对恢复和重建中国农村合作医疗制度作进一步思考。
