Measuring the geography of opportunity [PDF]
Quantitative segregation research focuses almost exclusively on the spatial sorting of demographic groups. This research largely ignores the structural characteristics of neighborhoods – such as crime, job accessibility, and school quality – that likely ...

Neighborhoods and health [PDF]
Features of neighborhoods or residential environments may affect health and contribute to social and race/ethnic inequalities in health. The study of neighborhood health effects has grown exponentially over the past 15 years. This chapter summarizes key work in this area with a particular focus on chronic disease outcomes (specifically obesity and ...

Predictors of Academic Achievement among Physical Education and Sports Undergraduate Students
Although a number of studies have attempted to determine the antecedents, correlates, and consequences of students’ academic performance, there are few studies in the literature that examine the correlates of academic achievement for physical education ...

A Remark on the Second Neighborhood Problem [PDF]
Seymour's second neighborhood conjecture states that every simple digraph (without digons) has a vertex whose first out-neighborhood is at most as large as its second out-neighborhood. Such a vertex is said to have the second neighborhood property (SNP).

We define the block neighborhood of a reversible CA, which is related both to its decomposition into a product of block permutations and to quantum computing. We give a purely combinatorial characterization of the block neighborhood, which helps in two ways. First, it makes the computation of the block neighborhood of a given CA relatively easy. Second,

Cylindrically symmetric and plane-symmetric solutions in f(R) theory via Noether symmetries
The f(R) theory is considered for static cylindrically symmetric and plane-symmetric spacetimes. In order to find solutions to the field equations of these models, the Noether symmetry method is used.
