STUDY OBJECTIVE s: This study examines the influence of individual and neighbourhood socioeconomic status (SES) on mortality among black, Mexican-American, and white women and men in the US. The authors had three study objectives. Firstly, they examined mortality rates by both individual level SES (measured by income, education, and occupational/employment status) and neighbourhood level SES (i...

“Humanization of Neighborhoods Initiative” was launched in 2020, under the QoL program aiming at improving and adapting public spaces city Riyadh into pedestrian-friendly ones fewer cars' dependent which can help accomplish Saudi Vision 2030. This research aims investigating reflections on urban social life neighborhoods focusing streets to promote activities walkability a prime physical activi...

The main result shows that a small perturbation of a univalent function is again a univalent function, hence a univalent function has a neighbourhood consisting entirely of univalent functions. For the particular choice of a linear function in the hypothesis of the main theorem, we obtain a corollary which is equivalent to the classical Noshiro–Warschawski–Wolff univalence criterion. We also pr...

Full proofs of results announced here are to be found in [lO]. We consider the problem of classifying germs of neighbourhoods of locally flat topological submanifolds. Let M be a fixed topological manifold. An r-neighbourhood of M is a pair (i, N) where N is a topological manifold of dimension n+r and i:M—*N a locally flat embedding satisfying i^ÇdN) —dM. Denote the set of germs of r-neighbourh...

Closure theorems in graph theory are of the following type: Let G be a graph, P a graph theoretic property, and let u and v be two non-adjacent vertices of G. If condition c(u, v) holds, then G has property P if and only if G+ uv has P. We discuss several such results of the above type where the condition c(u, v) refers to neighbourhood properties of u and v.

This paper discusses results from an experimental study of concept neighbourhoods in WordNet and Roget’s Thesaurus. The general aim of this research is to determine ways in which neighbourhood lattices can be derived in real time from a lexical database and displayed on the web. In order to be readable the lattices must not be too large, not contain overlapping concepts or labels and must be ca...
