Lay People Representations on the Common Good and Its Financial Provision

The financial contribution to the common good is a relevant issue to contemporary societies, especially in the wake of the Global Financial Crisis. In the economic literature, taxes and monetary donations have been regarded as two complementary ways of financially providing for the common good. In the psychological literature, instead, they have not been studied in conjunction. In-depth interviews have been conducted using interpretative phenomenological analysis (IPA) approach and a photo-elicitation technique to investigate the representations people share on the financial provision for the common good. Results suggest that both taxes and donations are seen as indirect, rather than direct, ways of providing for the common good. From a formal and cognitive level, paying taxes and making donations can be seen as two sides of the same coin, but they present differences at the affective level. When paying taxes, people are concerned mostly about the effects and expect a material exchange in return; when making a monetary donation, people are concerned mostly about the motivations and expect an emotional exchange in return

Sources and transfers of methylmercury in adjacent river and forest food webs

Nearly all ecosystems are contaminated with highly toxic methylmercury (MeHg), but the specific sources and pathways leading to the uptake of MeHg within and among food webs are not well understood. In this study, we report stable mercury (Hg) isotope compositions in food webs in a river and an adjacent forest in northern California and demonstrate the utility of Hg isotopes for studying MeHg sources and cross-habitat transfers. We observed large differences in both delta Hg-202 (mass-dependent fractionation) and Delta Hg-199 (mass-independent fractionation) within both food webs. The majority of isotopic variation within each food web could be accounted for by differing proportions of inorganic Hg [Hg(II)] and MeHg along food chains. We estimated mean isotope values of Hg(II) and MeHg in each habitat and found a large difference in delta Hg-202 between Hg(II) and MeHg (similar to 2.7 parts per thousand) in the forest but not in the river (similar to 0.25 parts per thousand). This is consistent with in situ Hg(II) methylation in the study river but suggests Hg(II) methylation may not be important in the forest. In fact, the similarity in delta Hg-202 between MeHg in forest food webs and Hg(II) in precipitation suggests that MeHg in forest food webs may be derived from atmospheric sources (e.g., rainfall, fog). Utilizing contrasting delta Hg-202 values between MeHg in river food webs (-1.0 parts per thousand) and MeHg in forest food webs (+0.7 parts per thousand), we estimate with a two-source mixing model that similar to 55% of MeHg in two riparian spiders is derived from riverine sources while similar to 45% of MeHg originates from terrestrial sources. Thus, stable Hg isotopes can provide new information on subtle differences in sources of MeHg and trace MeHg transfers within and among food webs in natural ecosystems.1148sciescopu

The facilitators and challenges of dying at home with dementia: a narrative synthesis

Background: It is reported that, given the right support, most people would prefer to die at home, yet a very small minority of people with dementia do so. At present, knowledge gaps remain on how best to support end-of-life care at home for people with dementia. Aim: To identify and understand the challenges and facilitators of providing end-of-life care at home for people with dementia. Design: Narrative synthesis of qualitative and quantitative data. Data sources: The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A systematic literature search was conducted across six electronic databases (AMED, BNI, CINAHL, EMBASE, MEDLINE and PsycINFO) and reference lists of key journals were searched up to July 2017. Results: Searches returned 1949 unique titles, of which seven studies met all the eligibility criteria (four quantitative and three qualitative). Six key themes were identified – four facilitators and two challenges. Facilitators included ‘support from health care professionals’, ‘informal caregiver resilience and extended social networks’, ‘medications and symptom management’ and ‘appropriate equipment and home adaptations’. Challenges included ‘issues with professional services’ and ‘worsening of physical or mental health’. Conclusion: People with dementia may not always require specialist palliative care at the end of life. Further research is required to overcome the methodological shortcomings of previous studies and establish how community development approaches to palliative care, such as compassionate communities, can support families to allow a greater number of people with dementia to die at home
