The Art of Nursing in a Postmodern Context

Notions of the "postmodern" pervade various fields of study, but have rarely been applied to the practice and theory of nursing. This paper uses some conceptions of the "postmodern" to remedy this. Though there are many contested usages of the term, here "postmodern" will be used broadly in a periodical sense to trace changes in society and culture from the "modernism" of the 18th and 19th centuries to current concerns about "postmodernism". How these changes have been reflected in nursing practice and nursing theory will be explored. The changing use of the term "modern" to describe up-to-date practice will be addressed in the course of this. It is suggested that contextualizing nursing as a social/cultural activity in this way offers perspectives which will help us untangle the conflicting agendas and issues which form the fabric of the social world in which current nursing takes place, enabling us to act more effectively in promoting our own professional agendas.

Modelling Atmospheric Concentrations of Ragweed Pollen From Local and Distant Sources

Pollen grains from the genus ragweed (Ambrosia spp.) are important aeroallergens. In Europe, the largest sources of atmospheric ragweed pollen are the Rhône Valley (France), parts of Northern Italy, the Pannonian Plain and Ukraine. Episodes of Long Distance Transport (LDT) of ragweed pollen from these centres can cover large parts of Europe and are predominantly studied using receptor based models (Smith et al., (2013) and references therein). The clinical impact of allergenic ragweed pollen arriving from distant sources remains unclear (Cecchi et al. 2010). Although a recent study has found the major allergens of ragweed in air samples collected in Poznań, Poland, during episodes of long-distance transport from the Pannonian Plain (Grewling et al. 2013). The source orientated models SILAM, DEHM, COSMO-Art, METRAS and ENVIRO-HIRLAM currently report having the capability of modelling atmospheric concentrations of pollen in Europe. The performance of such source-orientated models is strongly dependent on the quality of the emissions data, which is a focus of current research (e.g. Thibaudon et al. (2014)). The output from these models are important for warning allergy sufferers in areas polluted by ragweed, but could also be used to warn the public of ragweed pollen being transported into areas where the plant is not abundant. Areas outside of the main areas of ragweed infection that contain considerable local populations must, however, also include local scale models. These models can be used to predict local concentrations, even when LDT is not present. This concept of combined LDT and local scale calculations has been shown to be work for air pollutants and is considered usable for urban scale calculations of aeroallergens once urban scale maps of aeroallergen sources have been produced.
