BACKGROUND The effects of ambient air pollution on pregnancy outcomes are under debate. Previous studies have used different air pollution exposure assessment methods. The considerable traffic-related intra-urban spatial variation needs to be considered in exposure assessment. Residential proximity to traffic is a proxy for traffic-related exposures that takes into account within-city contrasts...

Thirty nests of Hammond’s (Empidonax hammondii) and 88 nests of Pacificslope (E. difficilis) Flycatchers were located in different-aged Douglas-fir (Pseudotsuga menziesii)/tanoak (Lithocarpus densiflorus) dominated forests at 12 study sites in northwestern California during the breeding seasons of 1984, 1985, 1987, and 1988. In contrast to Pacificslope Flycatchers, Hammond’s used nest trees tha...

BACKGROUND Although many studies have reported the association between neighborhood built environment (BE) and physical activity (PA), less is known about the associations for older populations or in countries besides the US and Australia. The aim of this paper is to examine the associations for older adult populations in Japan. METHODS Our analyses were based on cross-sectional data from the...

BACKGROUND When measuring neighbourhood effects on health, it is both incorrect to treat individuals as if they were static and tied to their residential neighbourhood and to consider neighbourhoods rigid places whose geographical scales can be delineated a priori. We propose here to investigate the effects of residential medical density on health-seeking behaviours, taking into account the mon...

It is well known that the density and anisotropy profile in the inner regions of a stellar system with positive phase-space distribution function are not fully independent. Here we study the interplay between density profile and orbital anisotropy at large radii in physically admissible (consistent) stellar systems. The analysis is carried out by using two-component (n-γ,γ1) spherical self-cons...

This experiment tested whether locus equation coefficients, slope, and y-intercept could serve as indices of place of articulation for obstruents sharing the same place of articulation across different manner classes. Locus equations for 22 speakers were derived from CV/t/ words with initial voiced stop /d/, voiceless aspirated stop /t/, nasal /n/, voiced fricative /z/, and voiceless fricative ...
