    Heritage and landscape education is crucial to training young people in active and responsible citizenship, protection of the public assets, appreciation of the cultural diversity and intergenerational dialogue. Therefore, it cannot be limited to sporadic experiences and on outstanding heritage and contexts but must be transdisciplinary, inclusive and practicable everywhere. This book relates the research and action project “Scuola Attiva Risorse” (ScAR), winner of the Polisocial Award that recognizes research for social purposes at the Politecnico di Milano. The text describes an experimental and innovative action delivered within the fragile context of the urban peripheries. This participatory process involved schools, universities, cultural institutions, administrations and private actors in interpreting and enhancing the “hidden” cultural heritage in Milan’s fringe neighbourhoods

    Neste trabalho, buscamos evidenciar a concepção de História da Biologia que é veiculada nos livros didáticos. Para tanto, analisamos três coleções de livros de Biologia destinados ao Ensino Médio, e alguns livros universitários usados em cursos de formação de professores. Ao analisar este material curricular foi possível observar que a história apresentada é desvinculada do contexto cultural de cada período histórico, o que pode levar o aluno a construir uma falsa representação da ciência e do fazer científico.In this work, we search forto evidences the conception of the History of Biology being is propagated in textbooks. We analyze three Biology book collections designed estined forto middle schooledium education, and some university books used in teacher education courses. When analyzing this curricular material it was possible to observe that the history of biology presented is disengaged from entailedofthe cultural context of each historical period, and this what can lead the student to construct a false representation of science and of scientific meaning making

    A model‐based protocol for the diagnosis of von Willebrand disease

    Von Willebrand disease (VWD) is one of the main inherited coagulation disorders. It is caused by a deficiency and/or a dysfunction of the von Willebrand factor (VWF), a fundamental multimeric glycoprotein involved in the hemostasis process. Correct detection of the disease is not an easy task because the disease manifests itself in many variants and a high intra-subject variability is observed. For these reasons, the diagnostic clinical trials typically rely on a 24-h sampling protocol, which makes the overall test long, stressful, and costly. Using a new pharmacokinetic model derived from Galvanin et al.'s 2014 study, this study aims at i) assessing the theoretical possibility to perform a shorter clinical test and ii) proposing a set of model-based diagnostic methods as a support for the clinical team. A preliminary information analysis is performed in order to understand which sampling instants are more informative for model identification. This allowed us to propose a novel, 8-h diagnostic protocol, which is still able to ensure model identifiability. Three alternative diagnostic methods are then proposed based on this short-length clinical protocol. One of them directly uses the pharmacokinetic model, whereas the other two are based on the use of three indices (two pharmacokinetic indices, namely clearance, total VWF released, and as third index the basal multimer ratio) to formulate the diagnosis problem as a classification one. The classification problem is then solved using K-nearest neighbours and linear discriminant analysis. Results show the theoretical feasibility of a VWD diagnosis based on a shorter protocol

    REVEALING THE EVERYDAY LANDSCAPE: INNOVATIVE SYSTEMS FOR HERITAGE EDUCATION IN SCHOOLS. THE SCAR (SCHOOL ACTIVATES RESOURCES) PROJECT

    Get PDF
    The Italian Plan for Cultural Heritage Education identifies in the training related to cultural heritage the possibility of contributing to the cultural and social improvement of the life of every person, also developing, through a conscious use, the sense of belonging to one or more cultures and territory.Given these potentialities, the document reveals a lack of responses to training needs and underlines how the launch of educational courses that put school and university in synergy in the places of culture are among the priorities to be achieved in the period 2016-2018. The Italian Digital School Plan also stresses the importance of a renewed educational approach and effort to promote heritage and provides that all students are offered courses on the digital management of Cultural Heritage. The interest in the heritage, after all, is identified by European policies as part of the right of every citizen to freely participate in cultural life.The ScAR (School Activates Resources) project, aims to respond to these requests with an experimental and methodologically innovative action, set in a context rich in critical issues and on a fragile and ScARcely recognized heritage such as that of a part of the Milanese urban periphery. The aim of the project is to promote the shared knowledge of the latent urban patrimony and increase, especially in young people, the sense of belonging to the neighbourhoods, the sense of active citizenship and the responsibility in the common good’s care. Another priority is to provide schools with tools for educational innovation, inclusion, and technological update, to limit early school leaving.</p

    The development of parental monitoring during adolescence : A meta-analysis

    Get PDF
    As adolescents grow up, one of the important developmental tasks is to individuate themselves and to become more autonomous from parents. This requires a realignment of the parent-adolescent communication. The current meta-analytic study aims at identifying developmental changes in parent-adolescent communication, conceptualized within the parental monitoring framework, as entailing parental solicitation, control and knowledge, and adolescent’s disclosure and secrecy. Thirty-one longitudinal studies published between 2000 and 2015 were identified and included in the current meta-analysis. Informants, age at assessment and study duration were tested as moderators. Results showed a low to medium normative decline in parental control (Cohen’s d = −.395, 95% CI [−.541, −.249]), knowledge (d = −.245,95% CI [−.331, −.160] and adolescence disclosure (d = −.147, 95% CI [−.204, −.090]), and an increase in adolescent’s secrecy (d = .194, CI [031, .356]). Parental solicitation decreased based on parents’ (d = −.242, 95% CI[−.376, −.109]) but not on adolescents’ reports (d = .038, 95% CI[−.099, .175]). Another significant moderator was the duration of the study, with studies longer than 2 years being able to detect a more pronounced change in parental control than studies lasting less than 2 years (≤2 years, d = −.139 vs. duration > 2 years, d = −.581). Limitations of the current knowledge and new directions of studies are discussed.Peer reviewe

Santarpia · J. Tellène · M. Carrier Résumé Objectif : Cette étude pilote de type qualitative et exploratoire vise à décrire les effets d'un nouveau protocole d'écriture poético-érotique (nommée SANTEL) sur la rééro-tisation de l'image du corps chez une femme, ayant vécu un cancer. Matériel et méthodes : Il s'agit d'un protocole composé de quatre étapes : une liste des phrases à caractères poétiques et érotiques à choisir, un texte à trous à remplir, des amorces de phrases ciblées sur le corps et en fin un poème libre. Madame V. a subi un cancer du sein nécessitant une ablation complète. Madame V. et son conjoint exécutent le protocole d'écriture séparément. Nous montrons les variations discursives des métaphores utilisées avant et après l'expérience de l'écriture, à travers le logiciel d'analyse qualitative QSR NVivo10. Résultats : Madame V. passera de la métaphore initiale « je me sens une extraterrestre » vers la plus atténuée « Non. Je me dis qu'extraterrestre c'était peut-être un peu énorme ». En plus, elle utilisera de nouvelles métaphores linguistiques du corps pour raconter son image du corps telles que « ce corps de chair blanche » et « une fleur qui s'ouvre délicatement ». Conclusion : Cet exercice spécifique d'écriture promet un type de « chirurgie perceptive-littéraire » dans le processus d'investissement sensuel et affectif après la rémission, une reconstruction perceptive et poétique de l'image érotique du corps.

We analyzed the linguistic metaphors of the body by QSR Nvivo10 software. Results: Using this protocol, we showed discourse variations of metaphors before and after the experience of writing. Patient V used " I feel like an alien " as a starting metaphor to describe her cancer experience and after poetic writing sessions, she used other bodily metaphors like " My body is a flower " and " My sensual and white flesh ". Conclusion: This poetic perspective promises a type of " perceptive-literary surgery " , characterized by a sensual investment process after remission: a poetic reconstruction of erotic body image.

    While the genetics of autism spectrum disorders (ASD) has been intensively studied, resulting in the identification of over 100 putative risk genes, the epigenetics of ASD has received less attention, and results have been inconsistent across studies. We aimed to investigate the contribution of DNA methylation (DNAm) to the risk of ASD and identify candidate biomarkers arising from the interaction of epigenetic mechanisms with genotype, gene expression, and cellular proportions. We performed DNAm differential analysis using whole blood samples from 75 discordant sibling pairs of the Italian Autism Network collection and estimated their cellular composition. We studied the correlation between DNAm and gene expression accounting for the potential effects of different genotypes on DNAm. We showed that the proportion of NK cells was significantly reduced in ASD siblings suggesting an imbalance in their immune system. We identified differentially methylated regions (DMRs) involved in neurogenesis and synaptic organization. Among candidate loci for ASD, we detected a DMR mapping to CLEC11A (neighboring SHANK1) where DNAm and gene expression were significantly and negatively correlated, independently from genotype effects. As reported in previous studies, we confirmed the involvement of immune functions in the pathophysiology of ASD. Notwithstanding the complexity of the disorder, suitable biomarkers such as CLEC11A and its neighbor SHANK1 can be discovered using integrative analyses even with peripheral tissues

    Background: Physical stress triggers the endothelium to release von Willebrand Factor (VWF) from the Weibel Palade bodies. Since VWF is a risk factor for arterial thrombosis, it is of great interest to discover determinants of VWF response to physical stress. We aimed to determine the main mediators of the VWF increase by exhaustive physical exercise. Methods: 105 healthy individuals (18-35 years) were included in this study. Each participant performed an incremental exhaustive exercise test on a cycle ergometer. Respiratory gas exchange measurements were obtained while cardiac function was continuously monitored. Blood was collected at baseline and directly after exhaustion. VWF antigen (VWF:Ag) levels, VWF collagen binding (VWF:CB) levels, ADAMTS13 activity and common variations in Syntaxin Binding Protein-5 (STXBP5, rs1039084 and rs9399599), Syntaxin-2 (STX2, rs7978987) and VWF (promoter, rs7965413) were determined. Results: The median VWF:Ag level at baseline was 0.94 IU/mL [IQR 0.8-1.1] and increased with 47% [IQR 25-73] after exhaustive exercise to a median maximum VWF:Ag of 1.38 IU/mL [IQR 1.1-1.8] (p<0.0001). VWF:CB levels and ADAMTS13 activity both also increased after exhaustive exercise (median increase 43% and 12%, both p<0.0001). The strongest determinants of the VWF:Ag level increase are performance related (p<0.0001). We observed a gender difference in VWF:Ag response to exercise (females 1.2 IU/mL; males 1.7 IU/mL, p = 0.001), which was associated by a difference in performance. Genetic variations in STXBP5, STX2 and the VWF promoter were not associated with VWF:Ag levels at baseline nor with the VWF:Ag increase. Conclusions: VWF:Ag levels strongly increase upon exhaustive exercise and this increase is strongly determined by physical fitness level and the intensity of the exercise, while there is no clear effect of genetic variation in STXBP5, STX2 and the VWF promoter

    HIF-driven SF3B1 induces KHK-C to enforce fructolysis and heart disease.

    Fructose is a major component of dietary sugar and its overconsumption exacerbates key pathological features of metabolic syndrome. The central fructose-metabolising enzyme is ketohexokinase (KHK), which exists in two isoforms: KHK-A and KHK-C, generated through mutually exclusive alternative splicing of KHK pre-mRNAs. KHK-C displays superior affinity for fructose compared with KHK-A and is produced primarily in the liver, thus restricting fructose metabolism almost exclusively to this organ. Here we show that myocardial hypoxia actuates fructose metabolism in human and mouse models of pathological cardiac hypertrophy through hypoxia-inducible factor 1α (HIF1α) activation of SF3B1 and SF3B1-mediated splice switching of KHK-A to KHK-C. Heart-specific depletion of SF3B1 or genetic ablation of Khk, but not Khk-A alone, in mice, suppresses pathological stress-induced fructose metabolism, growth and contractile dysfunction, thus defining signalling components and molecular underpinnings of a fructose metabolism regulatory system crucial for pathological growth
