We consider a congestible system serving multiple classes of customers who differ in their delay sensitivity and valuation of service (or product). Customers are endowed with convex-concave delay cost functions. A system manager offers a menu of lead times and corresponding prices to arriving customers, who then choose the lead-time–price pair that maximizes their net utility (value minus disut...

When Nez Perce speakers were presented with a cartoon depicting the interactions between Sue, the classmate, and the teacher, they judged both (1) and (2) to be appropriate utterances by the classmate. In (1), a 3rd person pronoun in the embedded clause co-refers with the matrix subject, Sue. In (2), a 1st person pronoun replaces it, with the same reference. In English, this second pattern is a...

While there has been a wealth of research on verbs of quotation in recent decades (Butters 1980, Blyth et al. 1990, Tagliamonte and Hudson 1999, Buchstaller 2001, Singler 2001, Waksler 2001, Rickford et al. 2007, Vandelanotte 2012), including studies focusing on African American English (AAE) (Cukor-Avila 2002, 2012), the discussion has focused on a handful of variables, most notably be like, g...

In this paper, a newsboy model is developed under uniformly distributed lead-time and demand that is an appropriate assumption in obtaining optimal relief inventory of humanitarian disasters. It is noteworthy that limited historical data are in hand on relief operations. Hence, analytical and approximate solutions for optimal relief order quan­tity were derived. The effect of lead-time uncertai...
