Global climate and atmospheric changes may interact in their effects on the diversity and composition of natural communities. We followed responses of an annual grassland to three years of all possible combinations of experimentally elevated CO 2 (ϩ300 ␮L/L), warming (ϩ80 W/m 2 , ϩϳ1ЊC), nitrogen deposition (ϩ7 g N·m Ϫ2 ·yr Ϫ1), and precipitation (ϩ50%).(More)
In this paper, we outline the three main concepts of 'ageism'; health maximisation ageism, productivity ageism, and fair innings ageism. We provide a methodological overview of the existing empirical literature on people's preferences regarding age and classify these studies according to the types of questions that have been asked. We consider some of the(More)
BACKGROUND Scotland has a policy aimed at increasing physical activity levels in the population, but evidence on how to achieve this is still developing. Studies that focus on encouraging real world participants to start physical activity in their settings are needed. The Walking for Well-being in the West study was designed to assess the effectiveness of a(More)

Contrary to empirical reports of inhibitory dysfunction in ADHD, parental reports suggest that when playing computer games, the inhibitory abilities of children with ADHD are unimpaired. This small-scale preliminary investigation into this phenomenon looks at inhibition of an ongoing response and activity exhibited by children with ADHD between 6 and 14(More)
Using conversation analysis (CA), we studied conversations between one United Kingdom-based epilepsy specialist and 13 patients with seizures in whom there was uncertainty about the diagnosis and for whom different treatment and investigational options were being considered. In line with recent communication guidance, the specialist offered some form of(More)
In cost-utility analysis, the numbers of quality-adjusted life years (QALYs) gained are aggregated according to the sum-ranking (or QALY maximisation) rule. This requires that the social value from health improvements is a simple product of gains in quality of life, length of life and the number of persons treated. The results from a systematic review of(More)
