    The role of urban built heritage in qualify and quantify resilience. Specific issues in Mediterranean city

    Get PDF
    The Mediterranean city represents a significant example of urban organism, based on masonry construction and characterized by typological processes of growth. The material consistency and the temporal continuity of built heritage in Mediterranean city make relevant its interpretation and analysis according to the resilient approach. The declination of this approach in many disciplines generated a substantial diversity among the definitions of resilience (Francis and Bekera, 2014). Consequently, frameworks, adopted for a quantitative or qualitative assessment, underline the lack of standardization and rigor in defining resilience measurements. A review of resilience literature and actual applications in urban context permit to understand that there are different operators working on the field: on the one hand there are international organizations, on the other hand there are academics. The review of both the two ambits of investigation intends to clarify specific properties and convergence points in order to trace an evolution of conceptual framework and to identify general features of urban resilience. This process is fundamental in focusing the main aims of the research program: the definition of the role of urban built heritage, given by the close correlation between masonry constructive technique, typologies and morphologies, its material value in urban system, and its relevance in Mediterranean city in constitution of urban resilience (UNISDR, 2012a). Despite an increasing number of academic studies concerning the role of built environment in defining and improving cities resilience, their major attention is still focused on street patterns and lifelines infrastructures. The paper concludes how the role of built heritage remains insufficiently explored and a correct definition of urban structure is still missing inside the domain of infrastructural resilience

    Bounds on Dark Matter annihilations from 21 cm data

    Get PDF
    The observation of an absorption feature in the 21 cm spectrum at redshift z17z\approx 17 implies bounds on Dark Matter annihilations for a broad range of masses, given that significant heating of the intergalactic medium would have erased such feature. The resulting bounds on the DM annihilation cross sections are comparable to the strongest ones from all other observables.Comment: 8 pages. v2: improved treatment of energy depositio

    Urban disaster resilience. The role of built heritage in historical Italian towns

    Get PDF
    The concept of Resilience is now closely related to Disaster Risk Reduction (DRR). The built heritage plays an increasingly important role in the definition and implementation of urban resilience to disasters. In particular, historical Italian towns represent a significant example of urban organism, evolved and adapted itself a result of the seismic history of the country, which has characterized morphologies, typologies and masonry construction techniques. The objective of the research is to provide a proposal for preventive strategies for the post-crisis reconstruction, aimed to the implementation of urban resilience

    Sex differences in emotional and meta-emotional intelligence in pre-adolescents and adolescents

    The study focuses on sex differences in emotional and meta-emotional intelligence in a sample of 355 pre-adolescents and 164 adolescents. Emotional and meta-emotional intelligence were measured using the multi-trait multi-method IE-ACCME test, allowing to define individuals' profiles of ability EI, emotional self-concept, meta-emotional knowledge, meta-emotional ability in self-evaluation and meta-emotional beliefs. Meta-emotional dimensions refer to the awareness of individuals about their emotional abilities and to their beliefs about the functioning of emotions in everyday life. Results demonstrated that girls scored better than boys in ability-EI, in particular in adolescents' group, whereas boys reported higher score than girls in emotional self-concept in both groups of age. Result about meta-emotional knowledge and meta-emotional ability in self-evaluation revealed that boys systematically overestimate their emotional abilities whereas girls, particularly in the adolescent group, tend to underestimate them. Finally, in both age groups, girls scored higher than males in metaemotional beliefs. The adoption of the meta-emotional intelligence framework may help to explain the discordances about sex differences found in previous studies using self-report vs. performance measures of EI. Moreover, it may contribute to shed light on the nature-nurture debate and on the role of meta-emotional variables for explaining sex differences in EI

    Beyond emotional intelligence: The new construct of meta-emotional intelligence

    Get PDF
    Meta-emotional intelligence is a recently developed multidimensional construct that, starting from the original ability model of emotional intelligence, focuses on the cognitive aspects of emotional abilities and on the metacognitive and meta-emotional processes that influence our emotional life. Thus, meta-emotional intelligence is the combination of emotional abilities and meta-emotional dimensions, such as the beliefs about emotions, the self-concept about one's emotional abilities, and the self-evaluation of performance. This article aims to illustrate the theoretical and methodological background of this construct and to describe the IE-ACCME test, an original multi-method tool that has been developed to measure the different variables that compose meta-emotional intelligence. Applications of this construct will be discussed, as well as future directions

    Misura della velocità della luce in argon liquido con il rivelatore ICARUS a Fermilab

    Get PDF
    Le camere a proiezione temporale ad argon liquido (LArTPC) sono rivelatori utilizzati per studiare le interazioni dei neutrini. Come suggerisce il nome, questi rivelatori usano come mezzo di interazione l'argon liquido, il quale, se eccitato, emette luce di scintillazione. Alcune proprietà fisiche della luce di scintillazione dell'argon liquido non sono ancora state studiate. L'esperimento ICARUS, attualmente in fase di presa dati a Fermilab negli Stati Uniti, può essere sfruttato per effettuare alcune di queste misure. In questo lavoro di tesi viene presentata una misura preliminare della velocità di gruppo della luce di scintillazione dell'argon liquido, sfruttando i diversi sotto-rivelatori di questo esperimento

    The Relationship between Coping Strategies and State Anxiety during COVID-19 Lockdown: The Role of Perceived Emotional Intelligence

    Get PDF
    Background: The outbreak of the COVID-19 pandemic has caused an unprecedented and unexpected change all around the globe. The long-term effects are still ongoing, especially those related to the confinement measures. The study took place during the first COVID-19 lockdown in Italy, where everyone was forced to stay home in order to reduce the spread of the virus. The aim was to investigate the role of perceived emotional intelligence abilities (PEI) in coping with COVID-19-related anxiety. Methods: A cross-sectional study design was employed, and this study used an online survey launched through social networks, inviting adults to participate. The participants anonymously completed a three-scale online measurement of self-reported emotional abilities, coping strategies (approach and avoidance), and state anxiety towards COVID-19. Results: perceived emotional intelligence and approach coping significantly predicted state anxiety. In addition, perceived emotional intelligence mediated the relationship between approach coping and state anxiety. Conclusions: the study highlights the positive role of perceived emotional abilities in dealing with the unprecedented event represented by the COVID-19 pandemic, and in particular, in coping with anxiety related to lockdown and confinement. Their results highlight the importance of fostering emotional intelligence for navigating critical life events

    On-site inspections of pavement damages evolution using GPR

    Ground-penetrating radar (GPR) is being increasingly used for pavements maintenance due to the wide range of applications spanning from physical to geometrical inspections, thereby allowing for a reliable diagnosis of the main causes of road structural damages. In this work, an off-ground GPR system was used to investigate a large-scale rural road network. Two sets of surveys were carried out in different time periods, with the main goals to i) localize the most critical sections; ii) monitor the evolution of previous damages and localize newborn deep faults, although not revealed at the pavement surface level; iii) analyze the causes of both evolution and emergence of faults by considering environmental and human factors. A 1-GHz GPR air-launched antenna was linked to an instrumented van for collecting data at traffic speed. Other support techniques (e.g. GPS data logger, odometer, HD video camera) were used for cross-checking,. Such centre frequency of investigation along with a 25-ns time window allow for a signal penetration of 900 mm, consistent with the deepest layer interfaces. The bottom of the array was 400 mm over the surface, with a minimum distance of 1200 mm from the van body. Scan length of maximum 10 km were provided for avoiding heavy computational loads. The rural road network was located in the District of Rieti, 100 km north from Rome, Italy, and mostly develops in a hilly and mountainous landscape. In most of the investigated roads, the carriageway consists in two lanes of 3.75 meters wide and two shoulders of 0.50 meters wide. A typical road section includes a HMA layer (65 mm average thickness), a base layer (100 mm average thickness), and a subbase layer (300 mm average thickness), as described by pavement design charts. The first set of surveys was carried out in two days at the beginning of spring in moderately dry conditions. Overall, 320-km-long inspections were performed in both travel directions, thereby showing a productivity of approximately 160 km/day at 40 km/h speed, on the average. After processing and first-checking, GPR profiles were divided into homogeneous sections according to the combination of different parameters (e.g. route analyzed, long distance conditions of regularity/irregularity in layers arrangement). In such context, a high consistency between surface damages, mismatches from the GPR scans, and boundary environmental conditions was demonstrated. In addition, deep mismatches were detected even for early-stage or unrevealed faults. The second set of surveys was carried out in autumn in high humidity conditions, due to recent rainfalls. 160 km of relevant routes from the same road network were investigated. Results showed a high consistency with those collected during the first-stage of surveys. Minor changes were found in those sections with low traffic loads (e.g. farther away from the biggest town of Rieti), whereas major mismatches were detected in wetlands (e.g. close to rivers), work zones, and nearby those sections already deeply damaged in the past. This work benefited from networking activities carried out within the EU funded COST Action TU1208 “Civil Engineering Applications of Ground Penetrating Radar”
