Legionella and risk management in hospitals - A bibliographic research methodology for people responsible for built environments and facility management

An ongoing research project investigates the roles and duties of persons responsible for the built environment with respect to risk management of water systems and Legionella prevention from a facility management’s perspective. Our literature review provides an approach for selecting and analysing abstracts of initially 177 journal articles, subjected to certain topic-specific inclusion and exclusion criteria. Different decision strategies of either logic ‘yes/no’, Boolean operators ‘OR’ or ‘AND’ and decisions for single counts or cumulative counts of the identified three principal keywords ‘Legionella’, ‘hospital’ and ‘water’, were completed. A final list of ten principal reference articles from 29 journals was compiled. It suggests that the interconnected perspective of water systems, Legionella and hospitals seems to be underrepresented in the field of the built environment and facility management. The term ‘stakeholder’, which would refer to decision-makers, was not found more than once. Our result is a useful summary of established sources of information on environmental Legionella research. The results can be helpful for those new to the topic

Mesoscale Atmospheric Transport of Ragweed Pollen Allergens from Infected to Uninfected Areas

Allergenic ragweed (Ambrosia spp.) pollen grains, after being released from anthers, can be dispersed by air masses far from their source. However, the action of air temperature,humidity and solar radiation on pollen grains in the atmosphere could impact on the ability of long distance transported (LDT) pollen to maintain allergenic potency. Here, we report that the major allergen of Ambrosia artemisiifolia pollen (Amb a 1) collected in ambient air during episodes of LDT still have immunoreactive properties. The amount of Amb a 1 found in LDT ragweed pollen grains was not constant and varied between episodes. In addition to allergens in pollen sized particles, we detected reactive Amb a 1 in subpollen sized respirable particles. These findings suggest that ragweed pollen grains have the potential to cause allergic reactions, not only in the heavily infested areas but, due to LDT episodes, also in the regions unaffected by ragweed populations

Outsourcing and its implications for market success : negative curvilinearity, firm resources, and competition

Over the past few decades, outsourcing has become a widely discussed and researched means for firms to change their performance. In this article, we attempt to link outsourcing to the market success of firms, specifically their market share. We argue that although firms may be able to increase their market share through outsourcing, this is only true up to a point, beyond which market share actually decreases as a consequence of further outsourcing. There is, in other words, a negatively curvilinear (inverted U) relationship between outsourcing and market share. We also hypothesize that the outsourcing–market share relationship is moderated negatively by both the strength of firm resources and the extent of competition in a firm‘s market. We empirically confirm these arguments through a panel data analysis containing over 19,000 observations on manufacturing firms, and offer some case examples to illustrate the mechanisms driving these results. We discuss implications for marketing research and practice
