The Met Office weather game: investigating how different methods for presenting probabilistic weather forecasts influence decision-making

To inform the way probabilistic forecasts would be displayed on their website, the UK Met Office ran an online game as a mass participation experiment to highlight the best methods of communicating uncertainty in rainfall and temperature forecasts, and to widen public engagement in uncertainty in weather forecasting. The game used a hypothetical “ice-cream seller” scenario and a randomized structure to test decision-making ability using different methods of representing uncertainty and to enable participants to experience being “lucky” or “unlucky” when the most likely forecast scenario did not occur. Data were collected on participant age, gender, educational attainment, and previous experience of environmental modelling. The large number of participants (n > 8000) that played the game has led to the collation of a unique large dataset with which to compare the impact on the decision-making ability of different weather forecast presentation ormats. This analysis demonstrates that within the game the provision of information regarding forecast uncertainty greatly improved decision-making ability and did not cause confusion in situations where providing the uncertainty added no further information

Perceptive responses and familiar staff facilitate meaningful engagement of older adults and family/care partners in long-term care home implementation science research during COVID-19

A novel registered practical nurse-led video conferencing approach using PIECESTM for team-based care planning was developed to engage family/care partners in the care of older adults. The objectives were to: (a) explore the experiences of older adults and family/care partners in collaborating in implementation science research in long-term care (LTC); (b) identify facilitators and barriers to engaging older adults and family/care partners in implementation science research; and (c) share recommendations to support the engagement of older adults and family/care partners in research. A qualitative descriptive design was used. Two older adults and two family/care partners from two Canadian LTC homes were involved in the research. Data, comprised of interviews with older adults and family/care partners, and notes from research team meetings, were analyzed using thematic analysis. Older adults and family/care partners perceived they made valuable contributions to the research project. They expressed beliefs that care delivery required improvements for older adults with responsive behaviours in LTC, which served as motivation to participate in the research project. Facilitating factors included the support of familiar LTC staff for older adults to engage in research activities and understanding the value of PIECES. A barrier to engagement for older adults was research terminology and processes described during team meetings. This research highlighted taken-for-granted factors in a collaborative research endeavour with older adults and family/care partners. One-on-one interaction, follow-up \u27reporting\u27 and presence of familiar LTC staff are needed to support meaningful engagement of older adults and family/care partners in research.

Complementary shifts in photoreceptor spectral tuning unlock the full adaptive potential of ultraviolet vision in birds

Color vision in birds is mediated by four types of cone photoreceptors whose maximal sensitivities (λmax) are evenly spaced across the light spectrum. In the course of avian evolution, the λmax of the most shortwave-sensitive cone, SWS1, has switched between violet (λmax > 400 nm) and ultraviolet (λmax < 380 nm) multiple times. This shift of the SWS1 opsin is accompanied by a corresponding short-wavelength shift in the spectrally adjacent SWS2 cone. Here, we show that SWS2 cone spectral tuning is mediated by modulating the ratio of two apocarotenoids, galloxanthin and 11',12'-dihydrogalloxanthin, which act as intracellular spectral filters in this cell type. We propose an enzymatic pathway that mediates the differential production of these apocarotenoids in the avian retina, and we use color vision modeling to demonstrate how correlated evolution of spectral tuning is necessary to achieve even sampling of the light spectrum and thereby maintain near-optimal color discrimination

Behaviour and Climate Change: Consumer Perceptions of Responsibility

This paper explores the under-researched notion of consumer responsibility, a potentially significant influence on consumer behaviour that marketers and policymakers may be able to harness as they attempt to respond to environmental challenges such as climate change. The paper uses data derived from a commercially motivated survey (n = 1513) to explore domestic consumption behaviours most closely associated with the issue of disruptive climate change. A measure of 'General Environmental Responsiveness' (GER) is used to test: (1) the effects of consumers both taking responsibility for their actions and placing responsibility on others for the consequences of their consumption behaviour; and (2) whether sociodemographic variables can aid the targeting of consumers by the level and type of responsibility and pro-environmental behavioural intentions expressed. The study's findings demonstrate clear, if not strong, relationships between consumer conceptions of responsibilities for causing and tackling climate change and environment-related consumer behaviour. The study's implications both challenge accepted wisdom about environment-related consumer behaviour and suggest avenues for future research

Community-associated Methicillin-resistant Staphylococcus aureus and Healthcare Risk Factors

To determine frequency of methicillin-resistant Staphylococcus aureus infections caused by strains typically associated with community-acquired infections (USA300) among persons with healthcare-related risk factors (HRFs), we evaluated surveillance data. Of patients with HRFs, 18%–28% had a "community-associated" strain, primarily USA300; of patients without HRFs, 26% had a "healthcare-associated" strain, typically USA100
