The Impact of Obesity on Wages: the Role of Personal Interactions and Job Selection
No full textWe estimate the effects of obesity on wages accounting for the workers' sorting into jobs requiring different levels of personal interactions in the workplace. Using data from the National Longitudinal Survey of Youth 1979 combined with detailed information about jobs from O*Net, we find a wage penalty for obese white women. This penalty is higher in jobs that require a high level of personal interactions. Accounting for job selection does not significantly change the estimated wage penalty
Elucidating the composition and the state of conservation of nitrocellulose-based animation cells by means of non-invasive and micro-destructive techniques
No full textThis paper presents the first study on Rodovetri, animation cels produced between the 1950s and the 1970s for the Italian television and conserved at the Museum of Industry and Labour “Musil” (Italy). Although these cels are considered as works of art and witnesses of Italian animation design, they have never been studied before. The study of one of the most endangered cel groups of the Musil collection is presented here. The main aims were to investigate the composition of these animation cels, to identify the materials used for painting the characters, and to assess the state of conservation of the cels. The results, which were obtained by means of a multi-analytical non-invasive and micro-destructive approach, underline the composition of the plastic substrate as nitrocellulose, while the painted layers – which contain a variety of pigments and dyes – were found to be bound with a mixture of plant gum and animal glue. This study also provides information on their state of conservation, in particular in relation to the de-nitration of plastic sheets. Important issues on the preventive conservation are also raised
Assessing eutrophication in transitional waters: a performance analysis of the Transitional Water Quality Index (TWQI) under seasonal fluctuations.
No full textThe Transitional Water Quality Index (TWQI) is a simple tool for assessing the trophic status in shallow transitional water ecosystems, that can be easily implemented from basic monitoring activities. It integrates six metrics: the main causal factors of eutrophication (N and P concentrations), key biological
elements (phytoplankton chlorophyll-a, benthic phanerogams and macroalgal cover) and an indicator of the eutrophication effects (dissolved oxygen saturation). This paper investigates the effectiveness of the TWQI to increase the confidence in trophic status assessment and to reduce the uncertainty due to temporal variability. The temporal variability of TWQI and its six single metrics, individually considered, were investigated in Venice Lagoon using data from 29 stations, sampled in July and October 2010, and 8 stations sampled monthly from April 2014 to March 2015. TWQI resulted less affected by seasonal fluctuations than the individual metrics, generally reducing the mean temporal variability by at least 50%. The influence of monitoring frequency on the uncertainty of the trophic status assessment was investigated as percent error of the TWQI annual mean. Means were firstly obtained from 12-monthly
samplings. Lower sampling frequencies were also simulated and the deviation from the annual mean derived by monthly sampling was estimated. Overall, the annual mean values of TWQI was much less affected by the sampling frequency than individual indicators (e.g. Dissolved Inorganic Nitrogen). Based on the performance analysis of this study that demonstrates its reliability and efficiency, the TWQI can be recommended as a routine index to be used in large-scale monitoring of the trophic status in shallow
transitional water ecosystems
La castidad de la doncella: erotismo y poesía en Cervantes
No full textThe question of eroticism on Cervantes’ poetry is a tricky point, which has to be analyzed in the light of the editorial works of the author, its poetical bet in a series of key parliaments, and the revision of some spicy elements in his poems, as well as a brief confrontation to contemporary poetry. To sum up, Cervantes’ eroticism (esthetic, moral, and sexual) is a question of genre which has no space on his poetry, so that its discard and its reflections about the subject are significant.La cuestión del erotismo en la poesía de Cervantes es un asunto peliagudo, que se tiene que examinar a la luz de las labores editoriales del ingenio, su apuesta poética en una serie de parlamentos clave y la revisión de los elementos picantes de sus poemas, así como en un rápido careo con la poesía de su tiempo. En breve, el erotismo cervantino (estético, moral y sexual) es una cuestión de género que no tenía entrada en la poesía, de modo que tanto su descarte como sus reflexiones al respecto son significativas de su idea poética

Characterization of the water soluble fraction in ultrafine, fine, and coarse atmospheric aerosol
No full textWater soluble organic carbon significantly contributes to aerosol's carbon mass and its chemical composition is poorly characterized due to the huge number of species. In this study, we determined 94 water-soluble compounds: inorganic ions (Cl−, Br−, I−, NO3−, SO42−,K+, Mg+, Na+, NH4+, Ca2+), organic acids (methanesulfonic acid and C2-C7 carboxylic acids), monosaccharides, alcohol-sugars, levoglucosan and its isomers, sucrose, phenolic compounds, free l- and d-amino acids and photo-oxidation products of α-pinene (cis-pinonic acid and pinic acid). The sampling was conducted using a micro-orifice uniform deposit impactor (MOUDI) at the urban area of Mestre-Venice from March to May 2016. The main aim of this work is to identify the source of each detected compound, evaluating its particle size distribution. Clear differences in size distributions were observed for each class of analyzed compounds.
The positive matrix factorization (PMF) model was used to identify six factors related to different sources: a) primary biogenic aerosol particles with particle size > 10 μm; b) secondary sulfate contribution; c) biomass burning; d) primary biogenic aerosol particles distributed between 10 and 1 μm; e) an aged sea salt input and f) SOA pinene. Each factor was also characterized by different composition in waters soluble compounds and different particles size distribution
