Motivated by call center cosourcing problems, we consider a service network operated under an overflow mechanism. Calls are first routed to an in-house (or dedicated) service station that has a finite waiting room. If the waiting room is full, the call is overflowed to an outside provider (an overflow station) that might also be serving overflows from other stations. We establish approximations...

When undergraduate students return to on-campus residences in the fall, they will find a number of new faces leading them into the college houses of the 21st century. Alongside the twelve faculty masters — one each for the University's 12 college houses — and the accompanying faculty fellows, the University has named the dozen house deans that will be responsible for both the administrative and...

Many species of birds use alarm calls to signal information about predators, including the level threat. Previous playback experiments suggest that urgency response towards heterospecific is phylogenetically conserved, notably in Paridae family. Using conducted on European great tits (Parus major), we tested whether this perceives mobbing produced by an allopatric non-Paridae species, Southern ...

Male sexual displays provide females with information that is crucial to their reproductive decisions. That same information is available to eavesdroppers, with potential consequences for both signaller and receiver. We present empirical evidence for size-dependent responses to intersexual communication by conspecific rivals. Acoustic features of a male house cricket's (Acheta domesticus) matin...

We invited thousands of existing and prospective patients to tour our state-of-the-art facility. We wanted to show off the hard work we had invested in selecting the office location, designing the floor plan and decorating the interior. We owe...
