The paper presents a visual notation for the Web Ontology Language (OWL) providing an integrated view on the classes and individuals of ontologies. The classes are displayed as circles, with the size of each circle representing its connectivity in the ontology. The individuals are represented as sections in the circles so that it is immediately clear from the visualization how many individuals ...

Instead of delegating control over private data to single large corporations, in friend-to-friend (F2F) systems users take control over their data into their own hands and they communicate only with users whom they know. In this paper we propose a push-pull-clone model for trust-based collaborative editing with contract deployed over F2F network. People specify contracts when they share data to...

Individual privacy settings allow members of Social Networking Sites (SNS) to share personal data with specifically selected contacts, such as close friends. This allows members to use SNS for sharing even more private data they would otherwise not want to share with all of their contacts. Although a considerable part of data sharing activities on SNS is limited to the direct contacts of its me...

Which friend do you want to spend time with—a happy friend who performs better than you or an unhappy friend who performs worse than you? The present research demonstrates that in such conflicting situations, when the desires for companionship and comparison are pitted against each other, one’s level of happiness plays an important role in one’s choice. Using hypothetical scenarios, we found th...

The erythroleukemia induced by Friend virus complex in adult mice is a multistage malignancy characterized by the emergence, late in the disease, of tumorigenic cell clones. We have previously shown that a significant proportion of these clones have unique rearrangements in their cellular p53 oncogene. The clonal relationships among Friend tumor cells isolated in the late stages of Friend eryth...

We conducted two studies to examine gender differences in response to Facebook status updates from same and opposite gender friends. Study 1 surveyed 522 undergraduate students (216 females and 306 males), and compared males’ and females’ responses to two Facebook status updates: one from a same gender friend and one from an opposite gender friend. Females’ public replies and private messages t...

Swiss mice injected subcutaneously with suspensions of spleen cells or an extract of spleens from mice infected with Friend virus develop resistance to subsequent intravenous inoculation of Friend virus. A single injection of either Friend virus or Friend cells induces resistance. Immunized mice display resistance when challenged 6 months after immunization and survive for at least 20 weeks aft...
