Rebound eff ects measure the behaviorally induced off set in the reduction of energy consumption following effi ciency improvements. Using panel estimation methods and household travel diary data collected in Germany between 1997 and 2009, this study identifi es the rebound eff ect in private transport by allowing for the possibility that fuel price elasticities – from which rebound eff ects ca...

Th e addition of predators can play a key role in structuring ecological communities through both consumptive and nonconsumptive eff ects. Stocking of piscivorous fi sh in lakes and similar experimental introductions have provided fundamental evidence in support of trophic cascade theory. Yet, the impact of piscivore addition on cross ecosystem subsidies and meso-predator resource use has not b...

Sexually transmitted infections other than HIV are important global health issues. They have, however, been neglected as a public-health priority and control eff orts continue to fail. Sexually transmitted infections, by their nature, aff ect individuals, who are part of partnerships and larger sexual networks, and in turn populations. We propose a framework of individual, partnership, and popu...

Eff ect of a quality-improvement intervention on end-of-life care in the intensive care unit: a randomized trial.

After publication of our recent article [1], it was brought to our attention that an inaccurate observation was made in the Results section. We stated that diff erent concentrations of SF have no eff ect on normal chondrocytes viability. However, Figure 1 demonstrates that SF concentra tions 500 and 1000 μmol/L signifi cantly increase chondrocytes viability compared with the control group. Th e...

1426 www.thelancet.com Vol 384 October 18, 2014 Authors’ reply We agree with Sally Blower and Brian Coburn that the aim of HIV prevention programmes is to reduce HIV incidence among men and women and that focusing resources on those locations with the greatest intensity of transmission can increase the eff ect of these programmes. When limited resources are allocated in a way that maximises the...

Evidence from clinical studies emphasizes the relevance of contextual psychosocial variables, including physicianpatient interactions, for treatment outcome [1]. Positive psychosocial infl uences on treatment outcomes are termed placebo eff ects, whereas negative infl uences are termed nocebo eff ects. Experimental research reveals that the psychosocial context of therapy induces biochemical ch...

Methods With primary care data from individuals in the Clinical Practice Research Datalink with BMI data, we fi tted Cox models to investigate associations between BMI and 22 of the most common cancers, adjusting for potential confounders. We fi tted linear then non-linear (spline) models; investigated eff ect modifi cation by sex, menopausal status, smoking, and age; and calculated population ...
