A Systematic Review on the Impact of the Social Confinement on People with Autism Spectrum Disorder and Their Caregivers during the COVID-19 Pandemic.
2021
The COVID-19 pandemic had imposed a variety of containment measures on the general population for prolonged periods. Confinement has had, and still has, social, economic, educational, health, and psychological consequences on the entire population. Objective: In this article, a systematic search has been performed based on studies carried out since the beginning of the pandemic, regarding the impact of these containment measures on the autism spectrum disorder (ASD) population and their caregivers. Method: We consulted six databases (i.e., PubMed, Medline, Embase, Scopus, Web of Science, and Science Direct) and selected ten studies that met the inclusion criteria. The chosen studies have be…
Losing DNA methylation at repetitive elements and breaking bad
2021
Abstract Background DNA methylation is an epigenetic chromatin mark that allows heterochromatin formation and gene silencing. It has a fundamental role in preserving genome stability (including chromosome stability) by controlling both gene expression and chromatin structure. Therefore, the onset of an incorrect pattern of DNA methylation is potentially dangerous for the cells. This is particularly important with respect to repetitive elements, which constitute the third of the human genome. Main body Repetitive sequences are involved in several cell processes, however, due to their intrinsic nature, they can be a source of genome instability. Thus, most repetitive elements are usually meth…
Scad-elastic net and the estimation of individual tourism expenditure determinants
2014
This paper introduces the use of scad-elastic net in the assessment of the determinants of individual tourist spending. This technique approaches two main estimation-related issues of primary importance. So far studies of tourism literature have made a wide use of classic regressions, whose results might be affected by multicollinearity. In addition, because of the absence of robust economic theory on tourism behavior, regressor selection is often left to researcher's choice when not driven by non-optimal automatic criteria. Scad-elastic net is an OLS model that accounts for both these problems by including two types of parameters constraints, namely the smoothly clipped absolute deviation …
Dispersal rate and parasitism by Closterocerus chamaeleon (Girault) after its release in Sicily to control Ophelimus maskelli (Ashmead) (Hymenoptera,…
2011
Abstract Spread of the exotic parasitoid Closterocerus chamaeleon (Girault) and its parasitism on the Eucalyptus gall wasp Ophelimus maskelli (Ashmead) (Hymenoptera, Eulophidae) were studied in Sicily after C. chamaeleon introduction in May 2006. Parasitoid spread was evaluated by sampling sites at increasing distances from the five release sites. C. chamaeleon quickly established and spread; within 5 months, it caused 62% parasitism at release sites and 38% parasitism at sites 2 km from release sites. One year after its introduction (spring 2007), C. chamaeleon was detected more than 50 km distant from release sites. By winter 2007–08, the parasitoid was recovered throughout Sicily and in …
Musikmoderne als Mittel der Standortbestimmung eines "geistigen deutschen Juden". Ein Blick auf Arnold Schönberg in einer Vorkriegsnovelle Arnold Zwe…
2020
The aim of this article is to present the concept of "Europamüdigkeit" described by the German-Jewish writer Arnold Zweig (1887-1968) in his early work. The analysed novella titled "Quartettsatz von Schönberg" from 1913 is focused on a young emigrant who is exhausted with the European culture and encounters the music of Viennese modernism, bringing a totally new perception of the old continent.
Towards Nearly Zero Energy and Environmentally Sustainable Agritourisms: The Effectiveness of the Application of the European Ecolabel Brand
2020
Tourism represents an important economic driver in Italy, being responsible for approximately 13.2% of the total GDP (a value higher than the reference European average) and for nearly 10% of the regional GDP. Among the touristic sectors, the agritourist ones show a persistent growth, experiencing in 2019 a 6.7 point percentage improvement compared to the 2017 figures. Given this situation, the transition towards a low-carbon path, affecting the building sector for some time, should also involve agritourist buildings, through the release of EU directives, member state laws, and technical rules. On the other hand, agritourism sites could be awarded the Community EU Ecolabel. Unfortunately, a…
Effectiveness of Virtual Reality for Children and Adolescents with Autism Spectrum Disorder: An Evidence-Based Systematic Review
2018
Autism Spectrum Disorder (ASD) is a neurodevelopmental disease that is specially characterized by impairments in social communication and social skills. ASD has a high prevalence in children, affecting 1 in 160 subjects. Virtual reality (VR) has emerged as an effective tool for intervention in the health field. Different recent papers have reviewed the VR-based treatments in ASD, but they have an important limitation because they only use clinical databases and do not include important technical indexes such as the Web of Science index or the Scimago Journal & Country Rank. To our knowledge, this is the first contribution that has carried out an evidence-based systematic review includin…
Ar ceļošanas vajadzībām saistītās informācijas sociālā tīklā FaceBook novērtējums
2019
Maģistra darba „Ar ceļošanas vajadzībām saistītās informācijas sociālā tīklā FaceBook novērtējums” ietvaros tika analizēta tūrisma informācijas satura sociālajā tīklā FaceBook atbilstība patērētāju vēlmēm un vajadzībām. Darba teorētiskā bāze balstās uz tūrisma nozares, patērētāju uzvedības un informācijas laikmeta komunikācijas teorijām, īpaši izceļot sociālo mediju teorijas, savukārt pētījuma veikšanai izmantotā metodoloģija ir kontentanalīze, aptaujas un eksperta intervija. Pētījuma gaitā tika analizēti 2091 FaceBook publikācijas, 300 aptaujas un viens eksperta viedoklis. Rezultātā tika izprastas ceļotāju vēlmes un vajadzības par tūrisma informācijas saturu sociālajā tīklā FaceBook, kuras…

Border surveys and Time Location Sampling (TLS): an application on incoming tourism in Sicily
2012
The increasing need of reliable and detailed information at a regional and subregional level poses some challenges related with the measurement of tourists flows, for tourism destination management, planning and promotion purposes,. The aim of this work is twofold; first, it intends to analyse and discuss the main features and limits of the official border surveys conducted in the majority of world’s countries, within the framework of Time Location Sampling (TLS) design; second, it suggests the implementation of TLS design at a subnational level, by presenting the sampling design of the survey on incoming tourists in Sicily, carried out between 2009-2010, aimed at estimating the unobserved …
