No full textHealth literacy and education: evidence from the English Longitudinal Study of Ageing
No full textWe estimate the causal effect of compulsory schooling on health literacy using data from the English Longitudinal Study of Ageing. We exploit the quasi-experimental setting produced by the UK’s 1944 Education Act. We estimate a positive effect of one additional year of schooling on health literacy among women, no significant effects among men. This result is in line with previous findings about the positive effects of compulsory schooling on own health among women and supports the idea that more schooling might have generated efficiency gains in the health production due to improved health literacy
Light-induced changes in photosynthesis and structure of cyanobacteria cultured biofilms from an Italian wastewater treatment plant
No full textThe photosynthetic and light acclimation capability of phototrophic biofilms collected seasonally from the wastewater treatment plant (WWTP) of Fiumicino Airport (Rome, Italy) was tested in culture at different irradiance conditions. Photosynthesis versus Irradiance (P/I) curves were recorded on 15, 30 and 45 day aged communities and chlorophylls, carotenoids and phycobiliproteins quantified. Light microscopy observations were performed to evaluate inoculum species composition and taxonomic shifts over time in cultured biofilms. Phototrophs acclimated to different irradiances by varying the photosynthetic efficiency, maximum photosynthetic rate and pigment content. Community age and biomass variation also affected photosynthesis-light response. Marked shifts towards the prevalence of cyanobacteria were observed in summer and autumn biofilms kept at the highest experimental irradiances. Data indicated high productivity and acclimation potential of cultured phototrophic biofilms in view of their application for bioremediation technologies
Influence of light and flow on taxon composition and photosynthesis of marine phototrophic biofilm in photobioreactors
No full textIn this study, marine biofilms were cultured in a flow-lane, semi-continuous photobioreactor at different irradiances and flows to evaluate their combined effect on biofilms' phototrophic composition and photosynthetic activity. Taxon richness, evaluated by different microscopy techniques, including transmission and scanning electron microscopy, resulted to be heavily reduced from source communities to mature cultures. The strongest decrease was observed for diatoms, which were overcome by cyanobacteria and green algae over time. Photosynthetic performance was investigated by pulse amplitude modulated fluorescence. Irradiance was the main driver of data distribution of the photosynthetic parameters rel.ETRmax and Ik, while flow rate affected alpha and Delta F/ Fm'. The combination of irradiance and flow rate affected Delta F/Fm' reflecting the photosynthetic performance of the most relatively abundant taxa. Higher Delta F/Fm' was attained when cyanobacteria and green algae were dominating, whilst lower Delta F/Fm' when diatoms occurred in the initial phase of biofilm development
Italian seaside destinations in comparison. The brand image assessment for destination branding co-creation.
No full textThe purpose of this paper is to propose a methodology for the assessment of a destination's image on the web. The study builds up a picture of 26 Italian coastal destinations through indexes and highlighting the reputation of the tourism services (attractions, restaurants, and accommodation). This can be a useful tool for destination managers to help monitor their destination's online reputation and support the brand building and management through a co-creation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
