Media(ting) Between Generations: Common Sense and Perceptions of New Media by Young People and Teachers

The wide spread of mobile communication devices, the expansion of social media and participatory media platforms, the ease to edit, share and produce media content, indicate a trend of change in the media system that influences the production and consumption of knowledge and generates new paths for the young\u2019s identity construction. This raises necessary questions about the ways not only young, but also the education agencies \u2013 school in particular \u2013 relate to these transformations, starting from taking into account the production of common sense on the use, risks and opportunities of the media. Based on these considerations, in this paper, we will discuss the results of a qualitative case study carried out in the Veneto Region (Italy) on upper secondary school students and teachers in order to detect and compare the perception that young and educators have of the media, trying to identify boundaries or land on which to build exchange opportunities for dialogue between the generations

Pediatric blood cancer survivors and tobacco use across adolescence and emerging adulthood: A narrative review

Scholars underline the pivotal role of tobacco cigarette smoking in carcinogenesis process for blood tumors. A controversial debate is represented by the diffusion of tobacco use in young cancer survivors that had a previous diagnosis of blood tumor during the childhood. Compared with their peers, scientific evidence highlights that pediatric survivors have more difficult to give-up cigarette smoking. Furthermore, tobacco-smoking is frequently linked with others risk behaviors as drinking or substance abuse. In reviewing the main knowledge on this topic, authors affirm the need for increasing research on blood cancer survivors in order to depict psychological characteristics of pediatric blood cancer survivors. Improving health decision-making skills in young survivors could reduce the risk to adopt un-healthy behaviors and increase psychological wellbeing. Furthermore, authors propose tailored antismoking interventions based on the knowledge of the psychological and cognitive factors that support smoking during the transition toward emerging-adulthood

The Social Appearance Anxiety Scale in Italian adolescent populations: Construct validation and group discrimination in community and clinical eating disorders samples

Anxiety in situations where one’s overall appearance (including body shape) may be negatively evaluated is hypothesized to play a central role in Eating Disorders (EDs) and in their co-occurrence with Social Anxiety Disorder (SAD). Three studies were conducted among community (N = 1995) and clinical (N = 703) ED samples of 11- to 18-year-old Italian girls and boys to (a) evaluate the psychometric qualities and measurement equivalence/invariance (ME/I) of the Social Appearance Anxiety (SAA) Scale (SAAS) and (b) determine to what extent SAA or other situational domains of social anxiety related to EDs distinguish adolescents with an ED only from those with SAD. Results upheld the one-factor structure and ME/I of the SAAS across samples, gender, age categories, and diagnostic status (i.e., ED participants with and without comorbid SAD). The SAAS demonstrated high internal consistency and 3-week test–retest reliability. The strength of the inter-relationships between SAAS and measures of body image, teasing about appearance, ED symptoms, depression, social anxiety, avoidance, and distress, as well as the ability of SAAS to discriminate community adolescents with high and low levels of ED symptoms and community participants from ED participants provided construct validity evidence. Only SAA strongly differentiated adolescents with any ED from those with comorbid SAD (23.2 %). Latent mean comparisons across all study groups were performed and discussed

Technology options for earthquake resistant, eco-efficient buildings in Europe: Research needs

The built environment corresponds to the largest industrial sector not only in economic terms, but also in terms of resource flow. Moreover, European citizens spend most of their lives inside buildings, therefore buildings turn out to be at the centre of social and economic activity. In that light, Europe is involved in several initiatives and strategies aimed to make this sector one of the most competitive and innovative, focusing on the achievement of the environmental and energy targets in line with 2020 Europe Strategy and EU 2050 Roadmap, but also ensuring safety both in ordinary conditions and in presence of exceptional events, such as earthquakes. While new buildings can be constructed with high performance levels, the older buildings which are predominantly characterized by low energy performance and seismic vulnerability, typically need renovation measures. This report has the aim to define the research needs for exploiting old buildings potential to deliver energy and CO2-emission savings, as well as societal and economic benefits, so that energy efficient and earthquake resistant buildings can have a pivotal role in a sustainable future. In the first part of the report, a detailed analysis of the main characteristics of European buildings in terms of age, size, ownership, location, structural typology is presented in order to define the predominant typology of the European existing building stock. Secondly, the seismic hazard in Europe and the earthquake vulnerability of European buildings are analysed. Finally, energy consumptions and environmental impacts in terms of use of resources, construction and demolition (C&D) wastes and CO2 emissions are described. The analysis of the present situation turns out to be essential in order to define the starting point to assess the current and new technology options, examined in the second part of the report and necessary to obtain eco-efficient and seismic resistant buildings. In addition, the benefits that a renovation project could bring against a demolition and reconstruction programme have been underlined. Once these inputs have been defined, the requalification needs and the importance to improve renovation strategies, considered as outputs of the analysis, are examined for each of the two above-mentioned parts of this study. Finally, a critical discussion on the importance of considering research needs for this topic, with a focus on barriers and challenges which a renovation programme has to face, has been carried out.JRC.G.5-European laboratory for structural assessmen

Statistical Characterization of Heterogeneous Dissolution Rates of Calcite from In situ and Real-Time AFM Imaging

Abstract The evolution of the surface topography of a calcite crystal subject to dissolution is documented through in situ real-time imaging obtained via atomic force microscopy (AFM). The dissolution process takes place by exposing the crystal surface to deionized water. AFM data allow detection of nucleation and expansion of mono- and multilayer rhombic etch pits and are employed to estimate the spreading rate of these structures. Spatially heterogeneous distributions of local dissolution rate are evaluated from the difference between topographic measurements taken at prescribed time intervals. We rest on a stochastic framework of analysis viewing the dissolution rate as a generalized sub-Gaussian (GSG) spatially correlated random process. Our analysis yields: (i) a quantitative assessment of the temporal evolution of the statistics of the dissolution rates as well as their spatial increments; (ii) a characterization of the degree of spatial correlation of dissolution rates and of the way this is linked to the various mechanisms involved in the dissolution process and highlighted through the experimental evidences. Our results indicate that the parameters driving the statistics of the GSG distribution and the spreading rate of the multilayer pits display a similar trend in time, thus suggesting that the evolution of these structures imprints the statistical features of local dissolution rates. Article Highlights We investigate dynamics of dissolution patterns on a calcite crystal in contact with deionized water via AFM imaging Temporal behavior of parameters of our statistical model is consistent with surface pattern evolution A nested model for the spatial correlation of rates embeds multiple mechanisms driving dissolution rate

Chapter The languages of wine: negotiating intercultural exchanges through translation

This paper discusses the cultural and linguistic mediation strategies involved in the compilation of a terminological tool aimed at facilitating the intercultural exchanges between Italy and China in the field of oenology, by taking the Dictionary of Italian wines and grape varieties (Italian - Chinese) (Bosc et al. 2019) as a case study. The main objectives of the dictionary compilation were the popularization of specialized wine language, the standardization of the names of Italian wines and grape varieties, and the translation of the Italian lexicographical definitions in Chinese. For this process to be effective in terms of intercultural communication and mediation, the negotiation of standardization and translation strategies needed to take into account the differences between the two cultures and languages involved as well as the constraints of the lexicographical genre. After delineating the historical background and presenting the purpose of the dictionary from the lexicographical perspective, the paper delves into the choices made in the compilation of the Chinese text

Solid biofuels production from agricultural residues and processing by-products by means of torrefaction treatment: the case of sunflower chain

The high heterogeneity of some residual biomasses makes rather difficult their energy use. Their standardisation is going to be a key aspect to get good quality biofuels from those residues. Torrefaction is an interesting process to improve the physical and chemical properties of lignocellulosic biomasses and to achieve standardisation. In the present study torrefaction has been employed on residues and by-products deriving from sunflower production chain, in particular sunflower stalks, husks and oil press cake. The thermal behaviour of these materials has been studied at first by thermogravimetric analysis in order to identify torrefaction temperatures range. Afterwards, different residence time and torrefaction temperatures have been tested in a bench top torrefaction reactor. Analyses of raw and torrefied materials have been carried out to assess the influence of the treatment. As a consequence of torrefaction, the carbon and ash contents increase while the volatilisation range reduces making the material more stable and standardised. Mass yield, energy yield and energy densification reach values of about 60%, 80% and 1.33 for sunflower stalks and 64%, 85% and 1.33 for sunflower oil press cake respectively. As highlighted by the results, torrefaction is more interesting for sunflower stalks than oil cake and husks due to their different original characteristics. Untreated oil press cake and husks, in fact, already show a good high heating value and, for this reason, their torrefaction should be mild to avoid an excessive ash concentration. On the contrary, for sunflower stalks the treatment is more useful and could be more severe
