Published: June 2021

The routine detection, surveillance, and reporting of novel SARS-CoV-2 variants is crucial, as these threaten to hinder global vaccination efforts. Herein we report a novel local variant with a non-synonymous mutation in the spike (S) protein P681H. This local Israeli variant was not associated with a higher infection rate or higher prevalence. Furthermore, the local variant was successfully neutralized by sera from fully vaccinated individuals at a comparable level to the B.1.1.7 variant and an Israel wild-type strain. While it is not a variant of concern, routine monitoring by sequencing is still required.

Published: June 2021

The Oxford-AstraZeneca ChAdOx1 nCoV-19 is a vaccine against the COVID-19 infection that was granted a conditional marketing authorization by the European Commission in January 2021. However, following a report from the Pharmacovigilance Risk Assessment Committee (PRAC) of European Medicines Agency, which reported an association with thrombo-embolic events (TEE), in particular disseminated intravascular coagulation (DIC) and cerebral venous sinus thrombosis (CVST), many European countries either limited it to individuals older than 55–60 years or suspended its use. We used publicly available data to carry out a quantitative benefit–risk analysis of the vaccine among people under 60 in Italy. Specifically, we used data from PRAC, Eudravigilance and ECDC to estimate the excess number of deaths for TEE, DIC and CVST expected in vaccine users, stratified by age groups. We then used data from the National Institute of Health to calculate age-specific COVID-19 mortality rates in Italy. Preventable deaths were calculated assuming a 72% vaccine efficacy over an eight-month period. Finally, the benefit–risk ratio of ChAdOx1 nCoV-19 vaccination was calculated as the ratio of preventable COVID-19 deaths to vaccine-related deaths, using Monte-Carlo simulations. We found that among subjects aged 20–29 years the benefit–risk (B-R) ratio was not clearly favorable (0.70; 95% Uncertainty Interval (UI): 0.27–2.11). However, in the other age groups the benefits of vaccination largely exceeded the risks (for age 30–49, B-R ratio: 22.9: 95%UI: 10.1–186.4). For age 50–59, B-R ratio: 1577.1: 95%UI: 1176.9–2121.5). Although many countries have limited the use of the ChAdOx1 nCoV-19 vaccine, the benefits of using this vaccine clearly outweigh the risks in people older than 30 years. Study limitations included risk of underreporting and that we did not provide age-specific estimates. The use of this vaccine should be a strategic and fundamental part of the immunization campaign considering its safety and efficacy in preventing COVID-19 and its complications.
Design-Based Approach for Analysing Survey Data in Veterinary Research
Authors: Yang D. Aaron , Laven Richard A.
Published: June 2021

Sample surveys are an essential approach used in veterinary research and investigation. A sample obtained from a well-designed sampling process along with robust data analysis can provide valuable insight into the attributes of the target population. Two approaches, design-based or model-based, can be used as inferential frameworks for analysing survey data. Compared to the model-based approach, the design-based approach is usually more straightforward and directly makes inferences about the finite target population (such as the dairy cows in a herd or dogs in a region) rather than an infinite superpopulation. In this paper, the concept of probability sampling and the design-based approach is briefly reviewed, followed by a discussion of the estimations and their justifications in the context of several different elementary sampling methods, including simple random sampling, stratified random sampling, and one-stage cluster sampling. Finally, a concrete example of a complex survey design (involving multistage sampling and stratification) is demonstrated, illustrating how finding unbiased estimators and their corresponding variance formulas for a complex survey builds on the techniques used in elementary sampling methods.

Authors: Velmatov A. A. , Dunin I. M.
Published: June 2021

The purpose of the research was to study the milk productivity and quality of milk crossbreds of Simmental × Ayrshire × Holstein cows different genotypes. The results of crossbreeding cows of Simmental breed with sires of Ayrshire and Red-and-White Holstein breeds have been presented in the article. In terms of milk yield cows of the genotype 1/16S×1/16A×7 / 8HRW surpassed their herdmates with the genotype 1/8S×1/8A×3/4HRW by 300 kg of milk, and cows with the genotype 1/4S×1/4A×1/2HRW by 703 kg (P ≥ 0,95). In animals with high-blood of Holstein breed a significant decrease in the protein content in milk has been observed by 0,1 abs.% (P ≥ 0,999), but in terms of milk protein yield they exceeded their herdmates by 3,9–13,6 kg. In terms of fat content in milk the advantage of cows of the genotype 1/4S×1/4A×1/2HRW has not been so significant and was 0,04–0,05 abs.%, and in terms of milk fat yield on the contrary crossbred cows with the genotype 1/16S×1/16A×7/8HRW exceeded their herdmates by 11,5–25,0 kg (P ≥ 0,95). According to the casein content milk cows with genotype 1/4S×1/4A×1/2HRW exceeded their herdmates by 0,05–0,08 abs.% (P ≥ 0,95), there were practically no differences in the concentration of serum proteins between the groups. Cows of genotype 1/16S×1/16A×7/8HRW were inferior to cows of genotype 1/4S×1/4A×1/2HRW in dry matter by 0,10–0,26 abs.% (P ≥ 0,05), SOMO by 0,06–0,21 abs.% (P ≥ 0,999). In the milk of cows the content of calcium ranged from 127,0 to 128,1 mg/%, phosphorus from 97,4 to 99,1 mg/%. Rennet clotting time is one of the technological indicators of milk quality was shorter in cows with the genotype 1/4S×1/4A×1/2HRW by 2,5–10,2 %. Thus, with the increase of part od blood of Holstein breed from 50,0 to 87,5 % the milk productivity and live weight of cows also increase, but at the same time the quality indicators of milk decrease. However, due to the high milk yield for lactation crossbreds with high-blood of Holstein breed produce more nutrients.

Authors: Dmitrik I. I. , Zavgorodnyaya G. V. , Pavlova M. I.
Published: June 2021

Increasing the production of wool and improving its quality characteristics for a number of years remains an urgent issue in breeding work with fine-fleeced sheep. In this regard the main purpose of the research was a comparative assessment of the age dynamics of the main properties of wool and the histostructure of the skin of the young ewes of Artlukh merino breed in the farm AC “Krasny Oktyabr” in the Kazbekov district in the Republic of Dagestan. It has been found that at the age of one year in the experemental young ewes the epidermis increased by 21,2 %, the pilar and reticular layers by 2,9 and 12,8 %, respectively, and the total skin thickness by 6,1 %. The biggest increase in skin thickness was due to the epidermis and the reticular layer as the number of fat cells increased. The width of the secretory parts of the sweat glands increased by 7,1 %, the sebaceous glands by 9,6 %, in this regard the amount of wool fat increased by 7,6 %. The studied parameters of the skin histostructure revealed that the number of hair follicles decreased by 6,8 % with age. This is due to the increase in the area of the skin due to the growth of the animal. The change in the basic properties of wool was as follows: the diameter of wool fibers increased by 5,6 %, the strength of wool decreased by 13,8 %. Comprehensive studies allowed us to recommend testing the main properties of wool and indicators of the histostructure of the skin of experimental animals when improving existing breeds and breeding new breeds and lines of sheep. Histological studies of the skin should be carried out at the age of 4,5 months, and the most objective indicators are the ratio of secondary and primary follicles, this will allow for early selection of lambs by wool density.

Tax risks as a threat to the economic security of the state tax burden, economic security
Authors: Gadzhiev N. G. , Konovalenko S. A. , Shogenov B. A.
Published: June 2021

In the modern economy, tax risks are far from the last in importance. First of all, this is due to the fact that taxes are the main sources of formation of the country’s budget and thereby create an economic basis for the existence of a state that can perform its functions only if there is adequate funding. The size and condition of the budget, in turn, have a regulatory effect on the economy. Taxation is an integral part of the modern system of redistributing funds between economic entities, and therefore the urgency of the problem of tax risks is beyond doubt. From the point of view of the state (represented by the tax authorities), tax risks are the likelihood of a taxpayer’s non-compliance with tax legislation, i.e. financial losses of budgets of all levels and the state as a whole. In other words, the tax risks of the state consist in the likelihood of receipt of smaller amounts of taxes in comparison with the planned volumes, which can lead to negative consequences, for example, to an unplanned budget deficit. Such consequences can limit the possibility of financing many budget expenditures, which will lead to a slowdown in economic growth as a whole. The purpose of the scientific article was to study the influence of the role of tax risks as an effective threat to ensure the functioning of the state’s economic security system. The theoretical and methodological basis of the study was the work of both Russian and foreign experts in the field of economic security of the state, as well as materials from the periodicals of leading economists. The main research methods used in writing the work were the method of theoretical systemic economic analysis, the monographic (descriptive) method.

Problems of analysis and forecasting of the level of technical equipment of agricultural enterprises (on the example of the Ryazan region)
Authors: Khudyakova Elena Viktorovna , Nikanorov Mikhail , Butyrin Vasilij Vladimirovich
Published: June 2021

Currently, the level of technical equipment of agricultural enterprises in the Russian Federation remains at a low level. On average, tractor availability in the country is 2–3 times less than in Kazakhstan and Belarus, and 20–30 times lower than in Western Europe and the United States. At the same time, agricultural production is faced with the task of achieving the level defined by the Food Security Doctrine in a number of industries, and increasing exports in a number of industries (production of cereals and industrial crops). In the Ryazan region, there is an appropriate resource potential for solving these problems. But the main factor constraining the increase in production is the insufficient development of the material and technical base. The dynamics of the number of major types of equipment over the past 10 years remains negative. At the same time, the region has a State program of the Ryazan region “Development of the agro-industrial complex until 2025”, which provides for a number of measures to maintain the level of technical equipment of agriculture. In this regard, the issue of scientific justification of the required amount of equipment and forecasting for the near future becomes relevant. On the regional scale, this is a difficult task, since traditional forecasting methods are not fully suitable for solving this problem due to the wide variety of production conditions in farms — soil fertility, climatic conditions, economic situation, specialization, etc. Therefore, we propose a method for determining the required amount of equipment and the amount of investment, based on the allocation of cluster groups and, then, the development of economic and mathematical models for the use of machine and tractor fleet for typical farms of each cluster group. This article analyzes the level of technical equipment of agriculture in the Ryazan region and identifies cluster groups of farms.
Multifunctional Indocyanine Green Applications for Fluorescence-Guided Laparoscopic Colorectal Surgery
Authors: Son Gyung Mo , Ahn Hong-min , Lee In Young , Ha Gi Won
Published: June 2021

Indocyanine green (ICG) could be applied for multiple functions such as fluorescent tumor localization, fluorescence lymph node mapping (FLNM), and intraoperative angiography in colorectal cancer surgery. With the near-infrared (NIR) systems, colonoscopic ICG tattooing can be used to define the early colorectal cancer that cannot be easily distinguished through the serosal surface. The lymphatic pathways can be visualized under the NIR system when ICG is injected through the submucosal or subserosal layer around the tumor. Intraoperative ICG angiography can be applied to find a favorable perfusion segment before the colon transection. Although all fluorescence functions are considered essential steps in image-guided surgery, it is difficult to perform multifunctional ICG applications in a single surgical procedure at once because complex protocols could interfere with each other. Therefore, we review the multifunctional ICG applications for fluorescent tumor localization, FLNM, and ICG angiography. We also discuss the optimal protocol for fluorescence-guided colorectal surgery.

«Non so scrivere inglese, a momenti neppure italiano… datemi una “giobba” qualsiasi»: gli emigrati italiani nel teatro di Nino Randazzo
Authors: Caria Marzia
Published: June 2021

L'articolo prende in esame la rappresentazione culturale, sociale e linguistica degli italiani emigrati in Australia nella scrittura per il teatro di Nino Randazzo, drammaturgo di origine eoliana, emigrato a Melbourne nel 1952, considerato uno degli autori più importanti e prolifici nel contesto della cosiddetta “letteratura dell'emigrazione”, e più in particolare della letteratura italo-australiana in lingua italiana. Di particolare interesse è il tema dei pregiudizi culturali e sociali degli anglo-australiani nei confronti delle persone di origine italiana, etichettati come ignoranti, impossibili da acculturare e disciplinare, in gran parte legati alle organizzazioni criminali, che parlano per lo più una varietà mista di italiano e inglese. Così, in particolare, nella commedia Il Sindaco d'Australia (1981), in cui l'immagine stereotipata (ma esilarante) dell'emigrante del sud Italia, impulsiva e ambiziosa, caratterizzata a livello linguistico dall'uso di termini italo-australiani; e nella commedia Victoria Market (1982), concepita da Randazzo come protesta contro la tendenza degli anglo-australiani a costruire stereotipi nei confronti degli italo-australiani, in questo caso quello del'italiano mafioso. Il teatro di Randazzo, tuttavia, riesce a distinguersi dalle opere della maggior parte dei drammaturghi italo-australiani di prima generazione per il suo tentativo di demistificare in modo divertente tali pregiudizi e luoghi comuni. È nella scelta di un tono popolare della commedia, ottenuta anche attraverso la sapiente mescolanza di forme italiane più tradizionali con termini italo-australiani tipici degli anni in cui sono ambientati gli eventi narrati, che risiedono gli aspetti specifici di questo autore.
Contatti linguistici e culturali tra le due sponde dell’Adriatico. L’italiano degli scrittori di origine albanese
Authors: Shabaj Flora
Published: June 2021

La letteratura migrante è un potente mezzo di espressione che offre una grande varietà di interpretazioni e una grande fonte di ispirazione per gli studiosi per indagare i diversi aspetti della vita e quelli della società. Trovandosi nel mezzo, gli autori migranti hanno l'opportunità di vivere (in) due o più lingue e culture unendole, cambiandole e plasmandole. È proprio qui che avviene il contatto linguistico e dove si svolgono diverse strategie che diventano una parte interessante di una ricerca linguistica e letteraria. Questo articolo indaga il contatto tra la lingua albanese e quella italiana attraverso l'analisi di alcune opere di Ornela Vorpsi, Artur Spanjolli, Ron Kubati e Anilda Ibrahimi. Considerando il fatto che questi autori hanno deciso di utilizzare l'italiano come lingua di espressione, questa indagine offre alcune considerazioni su cosa questo significhi per loro e sull'impatto su entrambe le lingue. Considerando il fatto che questi scrittori trasferiscono nei loro testi non solo aspetti importanti della cultura ma anche alcune caratteristiche della lingua albanese, è interessante vedere il modo in cui avviene il transfert e cosa succede al testo quando due lingue diverse e distanti come albanese e italiano si incontrano.

Manokwari Regency is one of the districts in West Papua Province which has the potential for moderate to high Tsunami vulnerability. One of the vulnerable districts is East Manokwari District. Potential disaster vulnerability in an area should be followed by community preparedness. This is because when a disaster occurs, the community already understands what steps to take. This study aims to determine the level of overall preparedness of the community in Pasirido Village, East Manokwari District. This research was conducted for one month in January 2021 in Pasirido Village, East Manokwari District, Manokwari Regency. This research uses quantitative methods. The sample was determined using the method of puposive sampling with the category of the head of the family and has lived for 10 years in Kampung Pasirido so that a total sample of 30 respondents. Data collection was carried out by distributing questionnaires and interviews to respondents. The questionnaire used is a standard from LIPI-UNESCO / ISDR 2006 with parameters of knowledge and attitude (KA), emergency response plan (EP), disaster warning (WS), and resource mobilization (RMC). The results showed that the level of community preparedness on the parameters of knowledge and attitude was mostly in the very ready category of 67%. The level of community preparedness in the parameters of the emergency response plan was mostly in the very ready category of 60%. The level of community preparedness for disaster warning parameters in the very ready category was 93%. The level of community preparedness on the parameter of resource mobilization was mostly in the ready category of 80%. Based on these four categories, overall community preparedness for flood disasters is included in the very ready category of 77%. The recommendation of this study is the need to increase community preparedness by conducting training to simulations from related agencies to the community. This is so that all people in Pasirido Village are in the category of being very prepared to face the Tsunami disaster.

Fracciones de carbono y nitrógeno del suelo y productividad del trigo en el sudeste bonaerense, Argntina.
Authors: Landriscini Maria Rosa , Galantini Juan Alberto , Forján Horacio , García Ramiro Javier
Published: June 2021

El uso del suelo, las labranzas y las secuencias estivales, afectan la distribución y el contenido de carbono orgánico (CO), nitrógeno total (NT) y sus fracciones con diferente grado de labilidad. En la Chacra Experimental Integrada Barrow (INTA), se condujo un ensayo de larga duración, donde se evaluaron tres secuencias de cultivos, alternando leguminosas, oleaginosas y gramíneas, fertilización nitrogenada y labranza convencional. Los objetivos fueron: 1) determinar el efecto de las rotaciones y la fertilización sobre las fracciones orgánicas de C y N, 2) evaluar los cambios en el contenido de las fracciones con distinto grado de recalcitrancia (carbono orgánico mineral, COM y carbono orgánico recalcitrante, COR) e Índice de Recalcitrancia de C y N 3) evaluar la labilidad del C a través de las relaciones entre algunas fracciones de C y 4) estudiar el N potencialmente mineralizable, Nan, para conocer la capacidad de aportar N. La hidrólisis ácida separó las fracciones lábiles y recalcitrantes y se calculó el IR. Los cultivos aportaron diferentes cantidades de residuos ocasionando que cada sistema se comporte diferente aún con niveles semejantes de CO. Las secuencias con gramíneas y leguminosas, presentaron mayores concentraciones COT y de carbono orgánico particulado grueso, COPg, con 18% de labilidad. La secuencia con soja, cuyos residuos presentaron menor relación C:N, podría tener mayor susceptibilidad a la degradación química. El N potencialmente mineralizable no se asoció a las fracciones de C y fue más abundante en la secuencia con soja. Las oleaginosas resultan ser mejores antecesores que las gramíneas de verano en el rendimiento del trigo.

Authors: Pintos Garance Milton , Arbeletche Pedro
Published: June 2021

La soja ha tenido un importante crecimiento en los últimos 20 años, convirtiéndose en uno de los principales productos de exportación del Uruguay. Este trabajo se centra en describir y analizar la fase agrícola inserta en la cadena de valor de la soja, correspondiente a la zafra 2016/2017, planteando como objetivos cuantificar el valor agregado bruto (VAB) generado por esta fase y toda la cadena y elaborar el mapa de valor bruto de producción (VBP). Se identifica el principal producto, y a partir de este, se describe, cuantifican y analizan los costos (servicios o insumos intermedios utilizados) y el VBP generado por dicho producto. Se analizan los resultados en una matriz insumo-producto, obteniendo un VAB de 1.519 mill. U$S, representando este, un 39% del VBP total de la cadena. La fase agrícola es la que mayor aporta al VAB total (51%). La relación VAB/VBP generado en esta fase, indica que ésta, en su proceso de producción, agrega valor en un 55%, generando ganancias, después de impuestos, de 37%, rentas 12% y genera empleo a 1,9 trabajadores/1000 ha. Es una fase muy desarrollada e importante en la cadena, pero, no es la fase que ejerce poder y control sobre las demás.
Transformaciones productivas en la Cuenca del Salado y persistencia de la ganadería familiar (1999-2019)
Authors: Cieza Ramón Isidro
Published: June 2021

Este estudio analiza los cambios ocurridos en la Cuenca del Salado, en los últimos veinte años en un contexto de transformaciones para el sector agropecuario pampeano. El trabajo se basó en fuentes secundarias de información y entrevistas a informantes clave, tomando el Partido de Las Flores como estudio de caso. Los resultados presentan diferencias en las dinámicas productivas de la zona bajo estudio, con respecto a otras subregiones de la pampa húmeda. Del análisis de la información se desprende que el número de unidades productivas se mantiene en el periodo analizado, incluso con un aumento de las más pequeñas, planteando un proceso divergente al resto de la Región Pampeana. Las causales de estas diferencias se asocian a la cría bovina como actividad productiva predominante, el modelo tecnológico que la sostiene y la imposibilidad de desarrollo del capital concentrado. Las características de esta subregión han frenado, al menos parcialmente, el modelo tecnológico capital intensivo y el desarrollo de economías de escala, por lo que los sistemas productivos familiares continúan vigentes con base en la ganadería vacuna y el trabajo familiar.

Las ciudades reales del Reino de Cerdeña a lo largo de los siglos tuvieron que gestionar la casi permanente ausencia de sus reyes y señores. Para ello frecuentemente enviaron sus delegados para tratar asuntos de diversa índole con el monarca quien debía ser el centro de su gobierno. A lo largo del presente trabajo se exponen numerosos ejemplos de ello que permiten hacer un recorrido desde la conquista de la isla de Cerdeña por los reyes de Aragón y Cerdeña en los siglos XIV y XV hasta el fin del Regnum Sardiniae en 1847. Todo ello permite comprobar que las embajadas a la corte fueron una práctica reconocida y utilizada por las ciudades reales sardas durante más de cinco siglos.

New Pathogenic Viruses of Natural Foci in Primorye Isolated over the 80-Year History of the Institute: A Review of Virological Studies
Authors: Leonova GN , Belikov SI , Kondratov IG
Published: June 2021

Background: The discovery of a new viral disease called tick-borne encephalitis (TBE) in the Far East in 1937 triggered the thematic virology research on the Eurasian continent. The purpose of our study was to conduct a virological and epidemiological monitoring of tick-borne viral infections in the Primorsky Krai over an 80-year period. Materials and methods: Several hundreds of strains belonging to the viruses of the TBE complex (Flaviviridae family) and other families have been isolated; their biological, antigenic and molecular genetic characteristics have been studied. Results: The most complete picture of the Far Eastern population of the TBE virus was obtained in the 1990s based on whole genome sequencing of 50 TBEV strains isolated from patients with different clinical manifestations of the disease and from ixodid ticks. It was established that all the strains belong to the same Far Eastern subtype of TBEV with three clusters (Oshima-, Sofjin-, and Senzhang-). In 1972, the Powassan virus was first isolated from Haemaphisalis longicornis ticks on the Eurasian continent. Phylogenetic analysis based on the whole genome characteristics of the Spassk-9, Nadezdinsk-1991 and Partizansk-2006 strains, as well as the characteristics of five fragments of other Powassan virus strains, indicated that they all belong to the Powassan virus lineage I. The first comparative description of three strains Primorye-155-77, Primorye-20-79 and Primorye-185-91 of the Louping ill virus was given. A comprehensive study of the isolated Ozernoe strain of a deceased female patient enabled identification of the first clinical case of the lyssavirus disease in the Asian part of Russia. This strain is genetically close and has a common ancestor with the Irkut strain and is attributed to pathogens of the genus Lyssavirus, family Rhabdoviridae. Conclusion: Isolation of a highly pathogenic lyssavirus and several viruses of the TBE complex indicates the importance of such virology surveillance and proves the necessity of its continuation.

This study aims to determine the increase in the ability of teachers in preparing RPP Curriculum 2013 through academic supervision at SMP Negeri 2 Tanjungpinang in 2018. Academic supervision is a model of coaching carried out by principals or supervisors to teachers to help solve problems related to learning activities for quality. learning can be achieved optimally. School action research (PTS) is a type of quantitative research using Comparative Descriptive Analysis by comparing the results of the initial conditions with the results of the first cycle of local level upgrading techniques (In House Training) and the results of the second cycle with private conversation techniques. This research was conducted in two cycles. Academic supervision as a group (In House Training), with the results of the research cycle I RPP Curriculum 2013 made by teachers is still not optimal, it is necessary to carry out further supervision in cycle II, namely the implementation of supervision measures individually (individual conversation). The average result of the teacher's ability to prepare RPP Curriculum 2013 in the initial conditions is 67.38 (sufficient category). The average result of the quality of the lesson plans compiled by the teacher in the first cycle was 75.02 (good category). The increase in the yield of cycle I compared to the initial conditions was 7.64. Meanwhile, the average quality of RPP Curriculum 2013 compiled by the teacher in cycle II was 81.89 (good category). The increase in the yield of cycle II compared to the result of cycle I was 6.37.

Performance Enhanced Coded OFDM with Almost Linear Interleaver over Rayleigh Fading Channels
Authors: han chenggao
Published: June 2021

This paper presents a comprehensive performance analysis of coded orthogonal frequency division multiplexing (COFDM) over the quasi-static multipath Rayleigh fading channels. We first analyze the pairwise error probability (PEP) of COFDM and then consider the union bound on bit error rate (BER) by introducing the notion of diversity guard (DG) and a novel interleaver class, named almost linear interleaver (ALI). A construction of ALI is also introduced with its parameter selection. Simulation results show that the COFDM with ALI outperforms that with random interleaver (RI) and the block interleaver (BI) adopted in the IEEE industry standards.

Published: June 2021

The present work focuses on the construct of digital citizenship from an educational and inclusive point of view. Considering the general European interest in implementing citizens’ digital skills and with particular care for the contemporary situation of overall emergency, due to the Covid 19 pandemic case, the idea is that of considering a possible conceptual link between digital skills and the Capability Approach. In the light of an ‘Education for all’, the aware development of teachers and, particularly support teachers’ digital skills, may be a crucial key to enact inclusive processes able to guarantee any pupil and student the chance to become a capable and valuable citizen, despite his/her frailties and social failures. This paper is part of a wider research project entitled “Best practices and tools of analysis in schools and community contexts: learning, teaching & inclusion”, started in March 2019 and funded by the Department of Psychological, Pedagogical Sciences, Physical Exercise and Training, of the University of Palermo, and of which just a segment related to the analysis of support teachers’ digital competence is reported here.
