ObjectivesPromoting cycling as a means of transport is now on multiple policy agendas, including health, and climate change. In this work, we use administrative data to explore whether cycle paths, particularly off road compared road, might increase the proportion people choosing work.
 MethodsOur work used from Edinburgh Glasgow, Scotland in 2011 at time population census. We limited our ...

With the development of information and communications technology, user-generated content and crowdsourced data are playing a large role in studies of transport and public health. Recently, Strava, a popular website and mobile app dedicated to tracking athletic activity (cycling and running), began offering a data service called Strava Metro, designed to help transportation researchers and urba...

Abstract Suppose that G is a finite group and X -conjugacy classes of involutions. The commuting involution graph $${\mathcal {C}}(G,X)$$ C ( G , X ) the whose vertex set with $$x, y \in X$$ x</...

OBJECTIVE To investigate the longitudinal associations between active commuting (walking and cycling to work) and body mass index (BMI). METHOD We used self-reported data on height, weight and active commuting from the Commuting and Health in Cambridge study (2009 to 2012; n=809). We used linear regression to test the associations between: a) maintenance of active commuting over one year and ...

BACKGROUND Promoting daily routine activities, such as active commuting to school, may have important health implications for young people. PURPOSE The aim of the study was to examine the secular trend of active commuting to school in Spanish adolescents over a 6-year period (2001-2002 to 2006-2007). We also examined several factors that might explain this trend. METHODS Data comes from two...

In a preceding paper the theory of nonsymmetric Macdonald polynomials taking values in modules Hecke algebra type A (Dunkl and Luque SLC 2012) was applied to such consisting anti-commuting variables, define superpolynomials. These depend on two parameters q,t are defined by means Yang–Baxter graph. The present determines subclass at special points 1,t,t2,… or 1,t−1,t−2,…. arguments use inductio...

Human mobility is a key component of large-scale spatial-transmission models of infectious diseases. Correctly modeling and quantifying human mobility is critical for improving epidemic control, but may be hindered by data incompleteness or unavailability. Here we explore the opportunity of using proxies for individual mobility to describe commuting flows and predict the diffusion of an influen...

BACKGROUND Active commuting is a good opportunity to accumulate physical activity (PA) across the lifespan that potentially might influence central body fat. We aimed to examine the prospective associations of active commuting at 11, 15 and 18 years of age with central body fat at 18 years. METHODS Participants were part of a large birth cohort study in Pelotas, Brazil (n = 3,649 participants...

We assessed commuting patterns in adolescents from 10 European cities and examined associations with physical activity (PA). A total of 3112 adolescents were included. PA was objectively measured with accelerometry. Commuting patterns and overall PA were self-reported using questions from the International Physical Activity Questionnaire modified for adolescents (IPAQ-A). Adolescents reported t...

Two operations commute if the result of their execution is independent of the order in which they execute. Commuting operations can be executed concurrently provided they execute atomically on the objects they access. Statically recognizing commuting operations is of great interest because they increase the amount of concurrency a compiler can exploit. In this document we introduce commutativit...
