What kind of housing choices will families with two paid workers make? Will higher income families still tend to live further away from the central city, as is the current U.S. pattern, leaving one worker (presumably the male) with a longer home-to-work commute, the other worker (presumably the female) with the shorter worktrip commute? Or will two salaried worker households locate homes, or ev...

BACKGROUND Few data exist on the risk of injury while commuting to work or school by bicycle. The proportion of commuters choosing to travel by bike is increasing in the United States, and information on injury incidence and the influences of rider characteristics and environmental factors may suggest opportunities for prevention actions. METHODS Bicycle commuters in the Portland, OR, metropo...

Abstract This study investigated the impact of extreme climate events on work absence in Jamaica. To this end, we constructed a quarterly individual level dataset labor market and climatic data for 2004–2014. We find that while excess rainfall increases odds being temporarily absent from work, heat is unlikely to have an effect. The estimated outcome reasonable given possibility flooded roads, ...

Active commuting could contribute to increasing physical activity. The objective of this study was to characterise patterns of active commuting to and from schools in children and adolescents in Chile. A total of 453 Chilean children and adolescents aged between 10 and 18 years were included in this study. Data regarding modes of commuting and commuting distance was collected using a validated ...

The rapid development of urban areas in surrounding regions has led to an increasing number commuters within and between core-peripheral regions. However, variation jobs economic levels exacerbated the socio-economic inequalities metropolitan residents. Using commuter data Jakarta Metropolitan Area, this study examines disparities commuting behaviour, spatial patterns, health with incomes lower...

OBJECTIVE To investigate the associations between body composition, cardiorespiratory and muscular fitness in relation to travel mode to school in children and adolescents. METHOD Children and adolescents from 40 elementary schools and 23 high schools representing all regions in Norway were invited to participate in the study. Anthropometry, cardiorespiratory and muscular fitness were tested ...

The spin 1/2 Calogero-Gaudin system and its q-deformation are exactly solved: a complete set of commuting observables is diagonalized, and the corresponding eigenvectors and eigenvalues are explicitly calculated. The method of solution is purely algebraic and relies on the co-algebra symmetry of the model. Running T itle: Spin 1/2 CG System and its q−Deformation P.A.C.S.: 03.65 Fd, 02.20 Sv

The exact scattering solutions of the Klein-Gordon equation in cylindrically symmetric field are constructed as eigenfunctions of a complete set of commuting operators. The matrix elements and the corresponding differential scattering cross-section are calculated. Properties of the pair production at various limits are discussed.

OBJECTIVE To assess whether prevalence of active commuting and regular car trips to school varies across communities and language regions in Switzerland and to determine personal and environmental correlates. METHODS During the school year 2004/2005, 1345 parental questionnaires (response rate 65%) of children attending 1st, 4th and 8th grades were completed, 1031 could be linked to a GIS env...
