Post-fire practices benefits on vegetation recovery and soil conservation in a Mediterranean area
2021
Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG. [Abstract] Post-fire practices (PFP) aim to reduce soil erosion and favour vegetation recovery, but their effectiveness is spatially heterogeneous and under debate because of the economic and environmental costs. This study evaluates the different changes (Δ) of canopy cover (CC), sediment connectivity (SC) and local topography in four areas affected by the Pinet fire in eastern Spain (August 8th, 2018) and managed with: totally burnt with tree removal and long log erosion barriers (LEBs) (Pinet-1), partially burnt without PFP (Pinet-2), totally burnt with tree removal and short LEBs (Pinet-3), and totally burnt wit…
Magmatic signature in acid rain at Masaya volcano, Nicaragua: Inferences on element volatility during lava lake degassing
2021
Abstract Major, minor and trace element concentrations of single rainfall events were investigated at Masaya volcano (Nicaragua) in order to determine the relative contributions of volcanogenic elements. Most of the samples were collected in the summit area of the volcano around the Santiago crater, and two samples, representative of the local background, were collected at a 4.3 km upwind site. Samples from the summit are very acidic with pH down to 2.14 and contain large amounts of volcanogenic elements that can be clearly distinguished from the local background. These elements are released into the atmosphere from the continuously degassing lava lake of the Santiago crater, Masaya volcano…

Influence of bond deterioration on shear-flexure failure of prestressed girders with post-tensioned tendons
2021
Internal prestressing with bonded tendons suffers corrosion of wires and bond deterioration due to the bad infill of grouted sheaths. Many bridge girders show this state through cracking, deflections and in the worst cases, sudden failures. In Italy these are common situations, and the internal tendon corrosion is among the major causes of bridge degradation and damage, especially for grouted post-tensioned tendons. This paper presents the analysis of failure of prestressed cross-sections considering shear and flexure in the case of bond deterioration due to corrosion of internal post-tensioned tendons. The structural behaviour is analysed for different typologies of bridge deck composed of…
Ketone body 3-hydroxybutyrate as a biomarker of aggression
2021
Human aggression is a complex behaviour, the biological underpinnings of which remain poorly known. To gain insights into aggression biology, we studied relationships with aggression of 11 low-molecular-weight metabolites (amino acids, ketone bodies), processed using 1H nuclear magnetic resonance spectroscopy. We used a discovery sample of young adults and an independent adult replication sample. We studied 725 young adults from a population-based Finnish twin cohort born 1983–1987, with aggression levels rated in adolescence (ages 12, 14, 17) by multiple raters and blood plasma samples at age 22. Linear regression models specified metabolites as the response variable and aggression ratings…
Il profilo professionale dell’educatore dell’accoglienza: note pedagogiche sul valore dell’orientamento per i migranti
2021
Riflettere sui professionisti dell’accoglienza è un compito impegnativo e complesso. La complessità è dovuta al fatto che vi sono molteplici figure professionali che ruotano attorno al sistema di accoglienza dei migranti. Tra queste figure troviamo quella dell’educatore, il quale agisce nei contesti educativi multiculturali extrascolastici grazie alla propria formazione personale e al mandato istituzionale. Nei contesti educativi, fortemente segnati dalla presenza di adolescenti migranti soli, l’educatore esercita una funzione di ascolto e aiuto, e lo fa affiancandosi nel percorso di crescita e maturazione dell’educando, mettendo al centro la relazione di cura e di fiducia. Soprattutto, egl…
A Process-Oriented View of Procedural Memory Can Help Better Understand Tourette’s Syndrome
2021
Tourette’s syndrome (TS) is a neurodevelopmental disorder characterized by repetitive movements and vocalizations, also known as tics. The phenomenology of tics and the underlying neurobiology of the disorder have suggested that the altered functioning of the procedural memory system might contribute to its etiology. However, contrary to the robust findings of impaired procedural memory in neurodevelopmental disorders of language, results from TS have been somewhat mixed. We review the previous studies in the field and note that they have reported normal, impaired, and even enhanced procedural performance. These mixed findings may be at least partially be explained by the diversity of the s…

Crisi globali, nuove diseguaglianze e co-produzione di spazi: una prospettiva di ricerca
2021
L’articolo propone una riflessione critica sul rischio di negazione sostanziale di diritti di cittadinanza a partire dalle forme di discriminazione nell’uso e fruizione dello spazio pubblico introdotte dalle crisi globali. La co-produzione di nuovi spazi alla micro-scala e alla scala di quartiere (a partire dagli spazi pubblici o semipubblici spesso privatizzati o sottoutilizzati) può divenire l’occasione per la generazione di nuovi luoghi di condivisione e socialità che rispondano alla richiesta di nuovi servizi e definiscano al contempo il profilo di una pratica urbanistica innovativa, fondata sul pieno riconoscimento del diritto alla città e sul patto istituzionicittadini This article pr…
Acceptance towards digital health interventions – Model validation and further development of the Unified Theory of Acceptance and Use of Technology
2021
Internet- and mobile-based interventions (IMI) offer an effective way to complement health care. Acceptance of IMI, a key facilitator of their implementation in routine care, is often low. Based on the Unified Theory of Acceptance and Use of Technology (UTAUT), this study validates and adapts the UTAUT to digital health care. Following a systematic literature search, 10 UTAUT-grounded original studies (N = 1588) assessing patients' and health professionals' acceptance of IMI for different somatic and mental health conditions were included. All included studies assessed Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions and acceptance as well as age, gender,…
Exploring the mediator role of self-critical rumination between emotion regulation and psychopathology: A validation study of the Self-Critical Rumin…

Network design for surface water quality monitoring in a road construction project using Gamma Test theory
2021
Road construction has a negative environmental impact on the surrounding aquatic environment, requiring the continuous monitoring of surface water quality. Here, optimization of the water quality monitoring network (WQMN) is an essential step in supporting the sustainable development of road construction projects. This study introduces Gamma Test theory (GTT) as a practical method for optimizing the WQMN of surface waters during road construction. The water quality index (WQI) was computed in 48 monitoring stations for six monitoring periods from 2017 to 2019; data was acquired from a primary monitoring network over a new highway in southern Norway. Based on the results, it is possible to r…
L'identità delle popolazioni anelleniche d'Occidente nel Peri Italias di Antioco di Siracusa
2021
Dealing with the origins of the populations settled in southern Italy and eastern Sicily Antiochus focuses on the theme of the autochthony of the Oenotrians, as well as other ethne originated from those, such as Italoi, Sicels and Morgetes. This can be especially inferred by the narrative context of fragment 2 (Jacoby), reported by Dionysius of Halicarnassus. The sketchy reference to the Italic Archaeology made by Antiochus, who mentions the Oenotrians as the oldest people in Italy, contrasts with traditions absorbed into Pherecydes’ work, according to which the Oenotrians were an ethnos of a distant Arcadian kinship, descending from the eponymous Lycaon, son of Oenotrus. Antiochus’ portray…

The right to education during the Italian pandemic. E-learning and inequality before the law
2021
Since the beginning of 2020 Italy have tried to give specific and rapid answers to the pandemic crisis, even if with strong compressions and limitations of constitutional fundamental rights, which has led to a huge debate among scholars about: the legislative instruments applied, the kind of legislation used, and on the merit of the measures enacted, having regard to their content and their compatibility with the constitutional principles and provisions, their legitimacy, their proportionality and the (un)fair balancing with the fundamental rights compressed and limited under their effects. Mostly, the crucial balancing work has involved, on one side, the right to health in its individual (…
Lipocalin-2 Regulates Hippocampal Microglial Activation in Poststroke Depression

2021
To compare perceived enjoyment (PE), % of heart rate peak (%HRpeak), blood lactate (La), rating of perceived exertion (RPE), and technical-tactical performance of soccer players after four-a-side (4vs4) and three-a-side (3vs3) small-sided games (SSGs) with goalkeepers.Sixteen males (20.7 ± 0.7 years; experience: 6.9 ± 1.2 years) completed and were measured after six sessions of SSGs (one twelve-minute bout (1x12), two six-minute bouts (2x6), and three four-minute bouts (3x4), both 3vs3 and 4vs4). Repeated measurements ANOVA evaluated significant differences (There was higher PE for 1 × 12 compared to 2 × 6 (effect sizes [ES] = 1.53 [3vs3 and 4vs4]) and 3 × 4 (ES = 3.13 [4vs4] and 4.16 [3vs3…
La necesidad de la teoría
2021
The need for theory is particularly necessary in our time, uncertain due to the crisis of foundations and knowledge for which architecture itself has become complex, full of contradictions, marked by infinite paths and sometimes unstable. The project cannot be entrusted to the contingencies of each case; creativity itself, daughter of intuition and chance, needs to be "worked" within the law, which is born from the mind and is built with logic so that the forms are appropriate and that everything is in the right place and to the extent. Especially in the Project Courses/Workshops of the first years, which constitute an "initiation" to the project, facing the theoretical moment is necessary …
Ecological dependencies make remote reef fish communities most vulnerable to coral loss
2021
Ecosystems face both local hazards, such as over-exploitation, and global hazards, such as climate change. Since the impact of local hazards attenuates with distance from humans, local extinction risk should decrease with remoteness, making faraway areas safe havens for biodiversity. However, isolation and reduced anthropogenic disturbance may increase ecological specialization in remote communities, and hence their vulnerability to secondary effects of diversity loss propagating through networks of interacting species. We show this to be true for reef fish communities across the globe. An increase in fish-coral dependency with the distance of coral reefs from human settlements, paired with…
On Defining the Participatory Museum: The Case of the Museum of the Second World War in Gdansk
2021
This article seeks to contribute to the current debate on the new definition of the “museum” – a debate which led to turmoil at the 2019 ICOM General Assembly in Kyoto. With reference to the case study of the Museum of the Second World War in Gdansk (MSWW), it analyses the new and very successful genre of the narrative museum, a genre which arguably fulfils the core elements of the definition currently being discussed by ICOM. In this regard, it brings into focus the paramount importance of community involvement in creating and managing narrative museums – an aspect that has been virtually absent in the academic and media debates over the nature of the MSWW and its programme. By pointing ou…
Personal Social Networks of Community-Dwelling Oldest Old During the Covid-19 Pandemic—A Qualitative Study
2021
The COVID-19 pandemic and its related restrictions have affected the everyday life of older people. Advanced age is a significant predisposing factor for a more severe COVID-19 infection, increasing the risk for hospitalization and mortality. Even though restrictions have been, thus, well-grounded, they may also have had detrimental effects on the social well-being of older people. Personal networks and social activity are known protective factors against the premature decline in health and functioning, and it is widely acknowledged that social isolation increases feelings of loneliness, poor quality of life, and even the risk for diseases and disabilities among older adults. This qualitati…

Cocleo-labirintopatie nel bambino. Come non perdere l'equilibrio.
2021
Cochleo-labyrinthopathy (CL) is an affection that involves cochlea and vestibular system. It occurs with the association of auditory symptoms (sensorineural hearing loss and tinnitus), vestibular symptoms (objective vertigo, unidirectional horizontal-rotary nystagmus and static or dynamic balance disorders) and neurovegetative signs (nausea, vomiting, pallor, sweating, etc.). The diagnosis may be difficult in paediatric age since the child is unable to clearly express their discomfort and symptoms. Multiple causes have been recognized but, in acute cases, infection is the most frequent etiological agent. The paper describes a case of CL due to Herpes Virus 1-2 infection responsive to acyclo…

Results: Multivariable models were based on 1183 patients with comple…
Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…
2021
Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…
Immune biomarkers to predict SARS-CoV-2 vaccine effectiveness in patients with hematological malignancies
2021
AbstractThere is evidence of reduced SARS-CoV-2 vaccine effectiveness in patients with hematological malignancies. We hypothesized that tumor and treatment-related immunosuppression can be depicted in peripheral blood, and that immune profiling prior to vaccination can help predict immunogenicity. We performed a comprehensive immunological characterization of 83 hematological patients before vaccination and measured IgM, IgG, and IgA antibody response to four viral antigens at day +7 after second-dose COVID-19 vaccination using multidimensional and computational flow cytometry. Health care practitioners of similar age were the control group (n = 102). Forty-four out of 59 immune cell types …
Performance-based characterization of recycled polymer modified asphalt mixture
2021
Due to the introduction of secondary materials, the asphalt mixtures to be designed and tested in our laboratories are constantly becoming much more complex than traditional asphalt mixtures making difficult to use conventional laboratory procedure and/or predict expected results. This study proposes a comprehensive characterization of asphalt mixture modified with recycled polymer compound by using both wet and dry process proposing adjustments to laboratory mixing and sample compaction procedure. Accordingly, three AC20 Hot Asphalt Mixture (HMA) were designed and their conventional and performance related properties were assessed by looking at a) Indirect Tensile test (ITS) a) moisture da…
