In a Peer Data Management System (PDMS), autonomous peers share semantically rich data. For queries to be translated across peers, a peer must provide a mapping to other peers in the PDMS; peers connected by such mappings are called acquaintances. To maximize query answering ability, a peer needs to optimize its choice of acquaintances. This paper introduces a novel framework for performing acq...

This article explores the dynamics of cases involving family and acquaintance sexual offenders who used the Internet to commit sex crimes against minors. Although the stereotype of Internet crimes involves unknown adults meeting juvenile victims online, Internet use can also play a role in sexual crimes against minors by family members and acquaintances. Data were collected from a national samp...

In this paper, we study the acquaintance time AC(G) defined for a connected graph G. We focus on G(n, r, p), a random subgraph of a random geometric graph in which n vertices are chosen uniformly at random and independently from [0, 1], and two vertices are adjacent with probability p if the Euclidean distance between them is at most r. We present asymptotic results for the acquaintance time of...

We tested the hypothesis that gifts act as markers of interpersonal similarity for both acquaintances and close relationship partners. Participants were led to believe that a new opposite sex acquaintance (Experiment 1) or romantic partner (Experiment 2) had selected either a desirable or undesirable gift for them. In Experiment 1, men viewed themselves as less similar to their new acquaintance...

The WWW has become the most important information system. But the demand of Web-based human interaction in a lot of situations, scenarios and applications e.g. electronic commerce and tele-learning, is still unsupported. Founding on a scenario-based requirements analysis we developed concepts, a client server architecture and a prototype of a basic group interaction system (gia-system). It curr...

That observers tend to agree in their ratings of a target even if they have never interacted with that target has been called consensus at zero acquaintance. The basic finding that consensus is highest for judgments concerning a target's degree of extraversion (EV) and somewhat weaker for judgments of conscientiousness is replicated. Several potential observable cues that might be used by judge...

Using a sample of 1010 women from a southeastern state university, we explore whether associations between fear of sexual assault and other crime-specific fears vary based on presumed victim-offender relationship. More specifically, we assess the extent to which fear of stranger- and acquaintance-perpetrated sexual assaults differ in the extent to which they are correlated with fear of other cr...

Interactions are a core part of all multi-agent systems. They occur because of the inter-dependencies which inevitably exist between the agents and they manifest themselves in many different forms—including cooperation, coordination, collaboration. However perhaps the most fundamental and powerful mechanism for managing these inter-agent dependencies at run-time is negotiation—the process by wh...
