“L’isola è un bell’organismo che si cura da sé”: percezioni e prospettive sulla salute dall’Isola del Giglio
No full textL’articolo si focalizza sull’analisi dei bisogni di salute percepiti dalla comunità in contesti di difficile accesso, quali le isole minori, argomento sempre più centrale nella ricerca scientifica e nell’agenda politica nazionale. Attraverso la descrizione dei risultati di un focus group tenutosi all’Isola del Giglio (Grosseto) nel mese di novembre 2018 con le principali istituzioni locali, si evidenziano le eventuali potenzialità e criticità del sistema salute dell’isola e i bisogni di salute e di assistenza così come percepiti dalla comunità. La metodologia qualitativa del community health needs assessment (valutazione dei bisogni di salute da parte della comunità) è utile per investigare percezioni e vissuti delle popolazioni di riferimento. I risultati fotografano una realtà isolana soddisfatta dei servizi legati alla salute presenti sull’isola, ma sottolineano, direttamente o indirettamente, altrettanti bisogni e fattori di rischio legati al contesto. In particolare, il tema del bisogno di potenziare le connessioni, e con esse il capitale sociale è il tema centrale della discussione. Il progetto di ottimizzazione dell’assistenza sanitaria nelle isole minori portato avanti dal Ministero della salute e dalle regioni interessate rappresenta un percorso fondamentale in questo senso
Evaluation of Cardiovascular Risk in Childhood: Data from a Survey of Dyslipidaemic Children
No full textDyslipidaemia is a well-known risk factor in developing cardiovascular disease (CVD) already in childhood
The Risk of Metabolic Syndrome among Dyslipidemic Children and Adolescents
No full textIn our outpatient setting of dyslipidemic children, the finding of high TG and low HDL levels helps in discriminating patients with MetS, especially when associated with increased BMI-SDS, insulin resistance and high SBP. Our data highlight the presence of a cluster of conditions that concurrently increased the cardiovascular risk already in childhood and, therefore, that had to be globally investigated
Life cycle assessment of lattice structures: Balancing mass saving and productivity
Full text linkAdditive Manufacturing has revolutionized manufacturing processes, offering design flexibility and advances in various applications. The integration of lattice structures into lightweight designs has attracted attention due to their ability to optimize properties such as stiffness, strength and energy absorption. This paper explores the trade-off between mass reduction and productivity while evaluating the environmental sustainability of lattice structures manufactured with Laser-based powder bed fusion for metals Using Life Cycle Assessment, two design variants for an automotive component are compared: a topologically optimized version with a solid bulk section, and a second design with lattice structures for additional weight reduction. Experimental measurements and a detailed analysis of the laser strategy were performed to build the Life Cycle Assessment inventory. The integration of lattice structures allowed a weight reduction of 6 %, but resulted in a significant decrease in productivity and a higher environmental impact. Surprisingly, lattice geometries, often perceived as green solutions, can have negative sustainability implications due to longer manufacturing times and impact of auxiliary equipment. Successful implementation of environmentally sustainable designs requires a balance between mass reduction and productivity while addressing potential environmental consequences
Detection of sub-superficial defects by infrared thermography in parts made by powder bed fusion with electron beam
Full text linkThe study explores Joule heating infrared thermography as a cost-effective alternative to computed tomography (CT) for detecting subsurface defects in parts produced by powder bed fusion with electron beam (PBF-EB). The primary objective was to quantify how surface roughness typical of different build orientations in PBF-EB affects thermographic data reliability. Simplified intentional defects of various sizes and depths were created in Ti6Al4V custom-samples under various target surfaces, whose morphology was characterized by confocal microscopy. CT scans provided accurate defect dimensions and revealed that sintered powder within defects does not significantly affect thermographic detection and can be treated as voids, paving the way to the application of the method to closed defects. The research led to the development and calibration of a reliable automated thermographic inspection protocol, the definition of best practices and key performance indicators for detectability, and the initiation of defect detectability maps tailored to the distinctive anisotropic features of additively manufactured parts

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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
