BACKGROUND AND AIMS The concept of national drinking culture is well established in research and policy debate, but rarely features in contemporary alcohol policy analysis. We aim to demonstrate the value of the alternative concept of social practices for quantitatively operationalizing drinking culture. We discuss how a practice perspective addresses limitations in existing analytical approach...

This article identifies a semantically motivated typology of lexicalization paths to account for the formation of nominal compounds from complex noun phrases. The typology includes coordination, semantic roles and possession, which, systematically, seems to be the origin of various subclasses of appositional, copulative and endocentric compounds, and the typology has serious implications for li...

Differential 2.2μm (K-band) luminosity functions are presented for a complete sample of 1570 nearby (Vgsr ≤ 3000 km/s, where Vgsr is the velocity measured with respect to the Galactic standard of rest), bright (K ≤ 10 mag), galaxies segregated by visible morphology. The K-band luminosity function for late-type spirals follows a power law that rises towards low luminosities whereas the K-band lu...

Data warehouse systems integrate data from heterogeneous sources. These sources are autonomous in nature and change independently of a data warehouse. Owing to changes in data sources, the content and the schema of a data warehouse may need to be changed for accurate decision making. Slowly changing dimensions and temporal data warehouses are the available solutions to manage changes in the con...

Pollen and charcoal analyses of sediments from northern coastal Taranaki, New Zealand, show that Maori settlement impacts on the vegetation began with the burning of tall coastal forest in the mid-17th century. Forest was replaced with a fern-shrubland, and small wetlands expanded with changing hydrological conditions. This forest clearance was much later than in most regions of the country, wh...

Amid widespread reports of deforestation, some nations have nevertheless experienced transitions from deforestation to reforestation. In a causal relationship, the Forest Identity relates the carbon sequestered in forests to the changing variables of national or regional forest area, growing stock density per area, biomass per growing stock volume, and carbon concentration in the biomass. It qu...
