Educar en la escuela infantil del siglo XXI: diálogo, inclusión y tecnología
2021
The objectives of education for the 21st century seek to guarantee an inclusive, quality and equitable process that fosters educational opportunities for all infants. Increasingly, minors are exposed for a longer time of digital consumption. Because of the increase in the number of screens in the home, as well as digital resources, we ask ourselves: What are the characte ristics of today's childhood? What place do technologies occupy in children and preschool teachers' lives? This article makes a bibliographic review that tries to answer these questions. The main objective is to elaborate the state of the art in relation to the development and implementation of digital technology in childho…
Green entrepreneurship and SME performance: the moderating effect of firm age
2021
AbstractGreen entrepreneurship has been increasing with growing attention to environment protection by a variety of stakeholders. Green innovation, as the essence of green entrepreneurship, has attracted a broad range of scholarly attention with yet inconclusive findings regarding its effect on firm performance. According to our analyses of 1667 firms listed on SME board and GEM in China during the period from 2010 to 2019, we find interesting results regarding the type of green innovation involved and the moderating effect of firm age on the link between green innovation and SME performance. More precisely, we find green utility-model innovation positively influences firm performance for S…
Reopening the Conversation Between Music Psychology and Music Therapy
2021
Although the fields of music psychology and music therapy share many common interests, research collaboration between the two fields is still somewhat rare. Previous work has identified that disciplinary identities and attitudes towards those in other disciplines are challenges to effective interdisciplinary research. The current study explores such attitudes in music therapy and music psychology. A sample of 123 music therapists and music psychologists answered an online survey regarding their attitudes towards potential interdisciplinary work between the two fields. Analysis of results suggested that participants’ judgements of the attitudes of members of the other discipline were not alw…

COVID-19 Prevention Measures Implemented by Tennis Coaches: The Role of Continent, Experience, and Type of Facility
2021
The prevention strategies used by tennis coaches when delivering tennis lessons during the COVID-19 pandemic were analyzed in this study. An ad hoc questionnaire collected data from 655 Spanish and Portuguese speaking tennis coaches working in Latin America and Europe. Differences in the prevention measures were analyzed according to the continent, the coaches’ experience, and the type of facility they worked in. Results showed that coaches used information provided from local and national organizations more than from international ones. Hand hygiene, communication of preventive strategies, and changes in the coaching methodology were the most used prevention measures. Latin American coache…
Exclusive heavy vector meson production at next-to-leading order in the dipole picture
2021
We calculate exclusive production of a longitudinally polarized heavy vector meson at next-to-leading order in the dipole picture. The large quark mass allows us to separately include both the first QCD correction proportional to the coupling constant $\alpha_s$, and the first relativistic correction suppressed by the quark velocity $v^2$. Both of these corrections are found to be numerically important in $\mathrm{J}/\psi$ production. The results obtained are directly suitable for phenomenological calculations. We also demonstrate how vector meson production provides complementary information to structure function analyses when one extracts the initial condition for the energy evolution of …
Determination of 60 Migrant Substances in Plastic Food Contact Materials by Vortex-Assisted Liquid-Liquid Extraction and GC-Q-Orbitrap HRMS
2021
A GC-HRMS analytical method for the determination of 60 migrant substances, including aldehydes, ketones, phthalates and other plasticizers, phenol derivatives, acrylates, and methacrylates, in plastic food contact materials (FCM) has been developed and validated. The proposed method includes migration tests, according to Commission Regulation (EU) 10/2011, using four food simulants (A, B, C, and D1), followed by vortex-assisted liquid–liquid extraction (VA-LLE) and GC-Q-Orbitrap HRMS analysis in selected ion monitoring (SIM) mode, with a resolving power of 30,000 FWHM and a mass accuracy ≤5 ppm. The method was validated, showing satisfactory linearity (R2 ≥ 0.98 from 40 to 400 …
Exhaled metabolite patterns to identify recent asthma exacerbations
2021
Asthma is a chronic respiratory disease that can lead to exacerbations, defined as acute episodes of worsening respiratory symptoms and lung function. Predicting the occurrence of these exacerbations is an important goal in asthma management. The measurement of exhaled breath by electronic nose (eNose) may allow for the monitoring of clinically unstable asthma and exacerbations. However, data on its ability to perform this is lacking. We aimed to evaluate whether eNose could identify patients that recently had asthma exacerbations. We performed a cross-sectional study, measuring exhaled breath using the SpiroNose in adults with a physician-reported diagnosis of asthma. Patients were randoml…
Per una archeologia dello spazio sepolcrale
2021
Attraverso questo contributo si intende sviluppare una sperimentale “misurazione critica”, di tipo strutturalista, finalizzata all’individuazione dei “principi formali” sottesi al progetto architettonico della tomba Brion. Sulla base delle argomentazioni teoriche elaborate da Vittorio Ugo in riferimento al problema degli archetipi dell’architettura, si propone una “archeo-logia” del complesso sepolcrale, con lo scopo di effettuare una “classificazione” delle forme interne al monumento. Due le macro-famiglie alle quali si fanno appartenere gli archetipi individuati: quella dell’“archeologia della natura” e quella dell’ “archeologia dell’architettura.
The Dynamic Relationship between Response Processes and Self-Regulation in Critical Thinking Assessments
2021
Our aim was to explore higher education students’ response and self-regulatory processes plus the relationship between these, as evidenced in two types of performance-based critical thinking tasks included in the Collegiate Learning Assessment (CLA+) International instrument. The data collection consisted of 20 cognitive laboratories. The data were analyzed using a qualitative approach. The tasks were found to trigger different response and self-regulatory processes. Overall, the performance task evoked more holistic processes than the selected-response questions, in which students’ processes were more question-oriented. The results also indicated the entanglement of students’ response and …
VPP: A Communication Schema for Population Protocols in VANET
2021
Population protocols are a new paradigm that aims to model distributed systems composed of randomly interacting mobile agents. The main advantage of this model is that, when certain theoretical assumptions hold, it is possible to formally demonstrate their convergence. We consider the problem of adopting Population Protocols in a real-world scenario that does not guarantee these assumptions. In particular, we consider the application domain of Vehicular Ad-Hoc Networks (VANETs) which are characterized by dynamic network topologies, and where wireless communications can be affected by interferences and errors. In this work, we analyze the main features of VANET agents and the communications …
Il docente universitario: personalizzazione ed autoefficacia percepita
2021
Per rispettare le misure di distanziamento imposte dal COVID-19, le Università hanno dovuto adottare la didattica a distanza (DaD). L’occasione è stata propizia per cercare di personalizzare il processo di insegnamento-apprendimento, vale a dire per centrare meglio la formazione erogata dalle Università sulle esigenze dei singoli studenti. L’attuazione dei principi della didattica personalizzata ha richiesto un impegno non indifferente ai docenti che vi si sono cimentati. È stato ipotizzato che la percezione della propria capacità di personalizzare la formazione degli studenti con il supporto delle tecnologie dell’informazione e della comunicazione, influisse sull’efficacia didattica dei do…

Beyond the screen
2021
Our didactic experiences in the field of architectural design, in courses that have always had a strong workshop character, have been varied in recent years and have been carried out in different variants that, when considered as a whole, allow us to reflect on the problems and the challenges faced during the pandemic. Indeed, a didactic normally conducted with compulsory attendance suffered in a sudden and unexpected way from the cancellation of physical presence, the loss of contact with people and the “corporeality” of the project. Moreover, the absence of the physical space of the classroom (a scene inherent to the laboratory) soon led to the search for new tools and appropriate methods…
Al di là dell’opposizione tra “malessere concettuale” e “cattiva coscienza”. Sul disagio dell’antropologia contemporanea di fronte al maltrattamento …
2021
In this paper I propose a critical examination of the ways in which the intersections between violence, suffering and domination in some of the main new directions of the anthropological study of the relationships between humans and other animals, notably Ingold's approach, Descola’s theory of “schemas of the practice”, and multispecies ethnography. Apparently, and despite the emphasis given to the sentience and forms of agency of non-human animals, as well as to their being active coparticipants, together with humans, in the construction of social networks and the habitats that bind both, these intersections do not occupy a prominent place in these approaches, both from the point of view o…
The Synbiotic Combination of Akkermansia muciniphila and Quercetin Ameliorates Early Obesity and NAFLD through Gut Microbiota Reshaping and Bile Acid…
2021
Gut microbiota plays a key role in obesity and non-alcoholic fatty liver disease (NAFLD), so synbiotics could be a therapeutic alternative. We aim to evaluate a nutritional intervention together with the administration of the bacteria Akkermansia muciniphila and the antioxidant quercetin in an in vivo model of early obesity and NAFLD. 21-day-old rats were fed with control or high-fat diet for six weeks. Then, all animals received control diet supplemented with/without quercetin and/or A. muciniphila for three weeks. Gut microbiota, NAFLD-related parameters, circulating bile acids (BAs) and liver gene expression were analyzed. The colonization with A. muciniphila was associated with less bod…
Recensione di Transizioni metropolitane : declinazioni locali delle dinamiche posturbane in Sicilia
2021
Sono trascorsi quasi vent’anni dalla pubblicazione di Postmetropolis (2000), il libro dell’urbanista statunitense Edward Soja che segnò il definitivo passaggio di testimone dalla scuola di studi urbani di Chicago a quella di Los Angeles. Da qui ripartono gli autori e le autrici di Transizioni postmetropolitane, il volume curato da Francesco Lo Piccolo, Marco Picone e Vincenzo Todaro per Franco Angeli (2018), che si inscrive all’interno del Progetto di Interesse Nazionale 2010-2011 dal titolo “Territori Postmetropolitani come forme urbane emergenti”. L’operazione teorica e analitica che sottende i singoli contributi è ambiziosa e può essere così riassunta: è possibile utilizzare i celebri se…
Fungal Contaminants and Mycotoxins in Nuts
2021
Contamination by fungi and mycotoxins in nuts has achieved much attention in recent years. In fact, the fungal metabolites produced by the species of Aspergillus, Penicillium (aflatoxins and ochratoxins), Fusarium (trichothecenes, zearalenones and fumonisins) and Alternaria (alternariotoxins) with toxic and/or carcinogenic effects are considered a threat to human and animal health. In this chapter we will discuss the main fungal taxa and related mycotoxins most frequently associated with these materials. In this regard, the first results on the level of contamination by fungi and mycotoxins in samples of almonds and pistachios of different origins will be reported. The main strategies to re…
Transcriptomic autophagy-related gene signature investigation for type 2 diabetes in Mediterranean subjects
2021
Abstract Background Autophagy (involving degradation and clearance of damaged organelles and compounds) plays a role in type 2 diabetes (T2D). There are three main types of autophagy and several genes involved. These genes have been well studied in animal models, but there are few transcriptomic studies in humans. Our aim is to analyze the differential gene expression, and the functional enrichment of the main autophagy-related genes (ARG) in T2D subjects from a Mediterranean population Methods We analyzed 120 White-European subjects (mean age 61,4 years; 50% women; 24 T2D) from Valencia, Spain. Clinical and lifestyle data were obtained. ARN was isolated from blood. Transcriptome-wide gene …

Ciprofloxacin carrier systems based on hectorite/halloysite hybrid hydrogels for potential wound healing applications
2021
The design of multifunctional nanomaterials which can help the healing processes of skin, preventing the bacterial infections, is crucial for the development of suitable therapy for the treatment of chronic lesions. The use of clay minerals in wound healing applications is well documented since the prehistoric period and offers several advantages due to their intrinsic properties. Herein, we report the development of ciprofloxacin carrier systems based on hectorite/halloysite (Ht/Hal) hybrid hydrogels for potential wound healing applications. To achieve this objective firstly the ciprofloxacin molecules were loaded onto Hal by a supramolecular and covalent approach. The so obtained fillers …
How important is culture to understand political protest?
2021
Abstract The literature considers nonviolent protests among the most important predictors of transitions towards democracy and democratic reforms. This study addresses the conditionsmaking countries more likely to experience nonviolent instead of violent forms of protest. While the literature emphasizes economic and political predictors of protest at the country level, we expand the study of nonviolent-vs-violent protest by incorporating cultural predictors. To do so, we use a newly developed time-pooled cross-sectional database covering an established set of orientations from the World Values Survey, known as “emancipative values”. Estimating the prevalence of these values at the country l…
Estimation of the effective diffusivity of blowing agents in closed-cell low-density polyurethane foams based on thermal aging data
2021
Abstract Low-density closed-cell polyurethane (PU) foams are applied as thermal insulation materials due to their low thermal conductivity imparted by that of the physical blowing agent (PBA) used in foam production. However, foam conductivity tends to gradually increase with time, primarily due to changes in the gas composition in foam cells brought about by gas diffusion. To enable predicting the variation of conductivity during the service life of foam insulation, gas diffusivities are usually determined by measuring the gas composition in foams at different aging times. This study considers an alternative approach of estimating the effective diffusivities of gases in PU foams, which is …
Understanding Different Approaches to ECE Pedagogy through Tensions
2021
Publisher Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland. The concept of pedagogy is the key to understanding pedagogy in early childhood education (ECE) in the Nordic countries, which are known for their high quality of life and education. However, in ECE, there are several different approaches toward pedagogy and it can be said that pedagogy is a multidimensional and dynamic concept. In this paper, the different approaches to pedagogy are defined and reconceptualized through an integrative literature analysis focusing on scientific papers and research reports of the concept. Five approaches to pedagogy were constructed: pedagogy through interaction, pedagogy through s…

The interplay of interoceptive accuracy, facets of interoceptive sensibility, and trait anxiety: A network analysis
2021
Abstract Interoception is the sense of the body's physiological state. Both the ability to accurately perceive bodily signals, and the self-reported sensibility for the body were assumed to be reciprocally associated with negative affect. Up to now, the specific interplay between dimensions of interoception and negative affect remains largely unknown. We investigated the interplay of cardioceptive accuracy assessed by a heartbeat tracking task, facets of interoceptive sensibility as measured by the Multidimensional Assessment of Interoceptive Awareness, and trait anxiety as measured by the trait version of the State-Trait-Anxiety inventory across two studies (n = 243) using a network analyt…

First light observations of the solar wind in the outer corona with the Metis coronagraph
2021
In this work, we present an investigation of the wind in the solar corona that has been initiated by observations of the resonantly scattered ultraviolet emission of the coronal plasma obtained with UVCS-SOHO, designed to measure the wind outflow speed by applying Doppler dimming diagnostics. Metis on Solar Orbiter complements the UVCS spectroscopic observations that were performed during solar activity cycle 23 by simultaneously imaging the polarized visible light and the H I Lyman-α corona in order to obtain high spatial and temporal resolution maps of the outward velocity of the continuously expanding solar atmosphere. The Metis observations, taken on May 15, 2020, provide the first H I …

Identification of Partner Proteins of the Algae Klebsormidium nitens NO Synthases: Toward a Better Understanding of NO Signaling in Eukaryotic Photos…
2021
In animals, NO is synthesized from L-arginine by three isoforms of nitric oxide synthase (NOS) enzyme. NO production and effects have also been reported in plants but the identification of its sources, especially the enzymatic ones, remains one of the critical issues in the field. NOS-like activities have been reported, although there are no homologs of mammalian NOS in the land plant genomes sequenced so far. However, several NOS homologs have been found in algal genomes and transcriptomes. A first study has characterized a functional NOS in the chlorophyte Ostreococcus tauri and the presence of NOS homologs was later confirmed in a dozen algae. These results raise the questions of the sig…
Model emulation to understand the joint effects of ice-nucleating particles and secondary ice production on deep convective anvil cirrus
2021
Abstract. Ice crystal formation in the mixed-phase region of deep convective clouds can affect the properties of climatically important convectively generated anvil clouds. Small ice crystals in the mixed-phase cloud region can be formed by heterogeneous ice nucleation by ice-nucleating particles (INP) and secondary ice production (SIP) by, for example, the Hallett-Mossop process. We quantify the effects of INP number concentration, the temperature dependence of the INP number concentration at mixedphase temperatures, and the Hallett-Mossop splinter production efficiency on the anvil of an idealised deep convective cloud using a Latin hypercube sampling method, which allows optimal coverage…

FANCD2 modulates the mitochondrial stress response to prevent common fragile site instability
2021
Common fragile sites (CFSs) are genomic regions frequently involved in cancer-associated rearrangements. Most CFSs lie within large genes, and their instability involves transcription- and replication-dependent mechanisms. Here, we uncover a role for the mitochondrial stress response pathway in the regulation of CFS stability in human cells. We show that FANCD2, a master regulator of CFS stability, dampens the activation of the mitochondrial stress response and prevents mitochondrial dysfunction. Genetic or pharmacological activation of mitochondrial stress signaling induces CFS gene expression and concomitant relocalization to CFSs of FANCD2. FANCD2 attenuates CFS gene transcription and pr…
