With the continuous improvement of people’s living standards, travel demand for vehicles increases rapidly during weekends and holidays. This situation leads to a number negative impacts on transport network, such as traffic congestion, carbon emissions, long queues at refueling stations. The impact requiring energy replenishment effect is nonlinear. Therefore, data working days cannot be direc...

Ambient ozone (O3) concentrations tend to be higher on weekends than on weekdays in urban areas, a phenomenon known as the weekend effect. Nevertheless, its downwind influence could be diverse. The MM5-CMAQ model has been used to assess the causes of weekday/weekend O3 differences in the north-eastern Iberian Peninsula during an episode of photochemical pollution covering the whole Western Medi...

BACKGROUND Vigorous-intensity physical activity (VPA) may confer superior health benefits for children compared to moderate-intensity physical activity (MPA), but the correlates of MPA and VPA may differ. The study purpose was to investigate associations between selected enabling, predisposing, and demographic physical activity correlates, and MPA and VPA during weekdays and at weekends. METH...

Some seabird species have learnt to efficiently exploit fishing discards from trawling activities. However, a discard ban has been proposed as necessary in Europe to ensure the sustainability of the seas. It is of crucial importance for the management and conservation purposes to study the potential consequences of a discard ban on the foraging ecology of threatened seabirds. We assessed the in...

BACKGROUND Little is known about how sitting time, alone or in combination with markers of physical activity (PA), influences mental well-being and work productivity. Given the need to develop workplace PA interventions that target employees' health related efficiency outcomes; this study examined the associations between self-reported sitting time, PA, mental well-being and work productivity i...

OBJECTIVE We assessed the EDs' characteristics associated with the offer and acceptance rates of a nontargeted HIV rapid-test screening in 29 Emergency Departments (EDs) in the metropolitan Paris region (11.7 million inhabitants), where half of France's new HIV cases are diagnosed annually. METHODS EDs nurses offered testing to all patients 18-64-year-old, able to provide consent, either with...

BACKGROUND AND PURPOSE Hip fractures are associated with high mortality, but the cause of this is still not entirely clear. We investigated the effect of surgical delay, weekends, holidays, and time of day admission on mortality in hip fracture patients. PATIENTS AND METHODS Using data from the Danish National Indicator Project, we identified 38,020 patients admitted from 2003 to 2010. Logist...
