Tip-of-the-tongue states may represent the momentary unavailability of an otherwise accessible word or the weak activation of an otherwise inaccessible word. In three experiments designed to address these alternative views, subjects attempted to retrieve rare target words from their definitions. The definitions were followed by cues that were related to the targets in sound, by cues that were r...

Introduction, motivation and policy relevance The main objective of this paper is to provide a framework for the assessment of the research activity and its impacts. This is a difficult task. First of all, because of the heterogeneity, partial overlapping and fragmentation of the different streams of literature. Secondly, due to the need of applying a systemic approach to account for the comple...

We consider voting situations in which some candidates may turn out to be unavailable. When determining availability is costly (e.g., in terms of money, time, or computation), voting prior to determining candidate availability and testing the winner’s availability after the vote may be beneficial. However, since few voting rules are robust to candidate deletion, winner determination requires a ...

Modern telecommunications systems are dependent on software for their successful operation. In many cases, the software operates on an established hardware platform and subsequent releases of the system differ primarily in the software component. Because of the increased dependence of the society on advanced telecommunications systems, the reliability and availability of network switching eleme...

Touch is a critical channel of communication used by mothers to communicate and interact with their infants and to contribute to their infants' socio-emotional development. The present study examined maternal touching in 41 mothers with and without depressive symptomatology. Mothers and their 4-month-old infants participated in the Still-Face (maternal emotional unavailability) and Separation (...

Cloud computing apparently helps in reducing costs and providing the scheduling optimal level. In practice however it may confront the problem of unavailability of resources. Taking into consideration the cloud computing bank with its somehow commercial nature, the resources unavailability, such as liquidity risk, remains. In this paper, an attempt to show through a solution so far applied in e...

In Cognitive Radio Mesh Networks (CogMesh), Secondary Mesh Routers (SMRs) can opportunistically utilize the licensed spectrums for the traffic of the Secondary Mesh Users (SMUs). How to guarantee Quality of Service (QoS) for real-time services over CogMesh is still an opening issue. In this paper, we present a discrete-time vacation queueing system to abstract the Primary User (PU) interruption...
