Response Conversion for improving comparability of International Physical Activity data.
BACKGROUND Many questionnaires for measuring physical activity (PA) exist. This complicates the comparison of outcomes. METHODS In 8 European countries, PA was measured in random samples of 600 persons, using the IPAQ as a 'bridge' to historical sets of country-specific questions. We assume that a unidimensional scale of PA ability exists on which items and respondents can be placed, irrespec...
متن کاملProcesses and patterns of oceanic nutrient limitation
1 The biomass of all living organisms consists of around 30 of the 92 naturally occurring elements (Fig. 1a and Supplementary Table S1)1,2. All organisms must obtain chemical forms of these essential elements, termed nutrients, from their external environment. The key role that nutrients play in controlling upper-ocean productivity has long been recognized3–5. Research over recent decades, howe...
متن کاملInorganic nutrient limitation of oceanic bacterioplankton
Although it is commonly accepted that dissolved organic carbon (DOC) of algal origin limits bacterial growth in pelagic systems, there arc relatively few empirical studies documenting this effect. Depending on site and season, both organic and inorganic nutrients can limit the growth of freshwater bacteria. By contrast, inorganic nutrients have only recently been implicated as potentially growt...
متن کاملComparability and reproducibility of biomedical data
With the development of novel assay technologies, biomedical experiments and analyses have gone through substantial evolution. Today, a typical experiment can simultaneously measure hundreds to thousands of individual features (e.g. genes) in dozens of biological conditions, resulting in gigabytes of data that need to be processed and analyzed. Because of the multiple steps involved in the data...
متن کاملMulti-nutrient, multi-group model of present and future oceanic phytoplankton communities
Phytoplankton community composition profoundly affects patterns of nutrient cycling and the dynamics of marine food webs; therefore predicting present and future phytoplankton community structure is crucial to understand how ocean ecosystems respond to physical forcing and nutrient limitations. We develop a mechanistic model of phytoplankton communities that includes multiple taxonomic groups (...
