Neighborhoods are good communities
The communities of a social network are sets of vertices with more connections inside the set than outside. We theoretically demonstrate that two commonly observed properties of social networks, heavy-tailed degree distributions and large clustering coefficients, imply the existence of vertex neighborhoods (also known as egonets) that are themselves good communities. We evaluate these neighborh...
متن کاملA Dynamical System for Neighborhoods in Plant Communities
How should plant ecologists scale up from the fine-scale events affecting individual plants in small neighborhoods to the coarse-scale dynamics of plant communities? We give here a dynamical system, derived from an individual-based model, that captures the main effects of spatial structure. The individual-based model describes a multispecies plant community, living in a spatial domain, containi...
متن کاملEnclosed residential neighborhoods in Israel: from landscapes of heritage and frontier enclaves to new gated communities
Contemporary studies of gated communities largely associate this phenomenon with global forces, emphasizing recent urban processes that operate across national borders. However, the Israeli experience demonstrates that multiple forces work simultaneously to produce various forms of enclosed residential communities that follow very different evolutionary routes. Older forms of gated spaces such ...
متن کاملNeighborhoods and Adolescent Development.
Researchers are increasingly interested in identifying specific aspects of adolescents' lives that are positively or adversely affected by their place of residence. This body of work suggests that it is important to consider neighborhoods when examining their 1) engagement in risk-related behaviors; 2) educational outcomes; 3) physical and mental health; and 4) their integration within social i...
متن کاملNeighborhoods, Ultrafilters, and Canonicity
This paper will remind the reader of neighborhood semantics for modal logics, compare them with relational semantics, and then look at some questions about neighborhood semantics that have been answered, and some which are still open. We will then introduce “ultrafilter semantics,” a way of expressing all sets over a canonical frame in an ‘effable’ way. This provides us with a conceptually easy...
