“A Transient Popularity”

A Popularity-driven Caching Scheme

Caching issues in meta-search engines are considered. We propose a popularity-driven cache algorithm that utilizes both popularities and reference counters of queries to determine cache data to be purged. We show how to calculate query popularity. Empirical evaluations and performance comparisons of popularity-driven caching with the least recently used (LRU) and least frequently used (LFU) sch...

Individual Popularity, Peer Group Popularity Composition and Adolescents’ Alcohol Consumption

Previous studies have convincingly shown associations between popularity and adolescent drinking. This study examined whether the popularity composition of the peer group and the relative difference in popularity between adolescents and their peers are also associated with adolescent drinking. Participants were 800 adolescents (M age = 14.73; SDage = 1.00; 51.6 % girls) from 31 classrooms who c...

A neural predictor of cultural popularity

We use neuroimaging to predict cultural popularity — something that is popular in the broadest sense and appeals to a large number of individuals. Neuroeconomic research suggests that activity in reward-related regions of the brain, notably the orbitofrontal cortex and ventral striatum, is predictive of future purchasing decisions, but it is unknown whether the neural signals of a small group o...

Sociometric Popularity in a School Context

Distributed Popularity Indices

Distributed hash tables (DHTs) are a distributed, peer-topeer analogue of hash indices in database systems. Given a key, a DHT returns a pointer to the associated object. DHTs have also be extended to support “keyword” queries [5, 2] (object identified by multiple keys). Fundamentally, however, these approaches all return a undirected sample of the full result set. Unfortunately, most applicati...
