    Get PDF
    AGENDA will be the main tool used in running the SPOT 4 Earth Observation Satellite's Operational Control Center. It will reduce the operator's work load and make the task easier. AGENDA sets up the work plan for a day of operations, automatically puts the day's tasks into sequence and monitors their progress in real time. Monitoring is centralized, and the tasks are run on different computers in the Center. Once informed of any problems, the operator can intervene at any time while an activity is taking place. To carry out the various functions, the operator has an advanced, efficient, ergonomic graphic interface based on X11 and OSF/MOTIF. Since AGENDA is the heart of the Center, it has to satisfy several constraints that have been taken into account during the various development phases. AGENDA is currently in its final development stages

    Astaxanthin is a carotenoid extracted from several seaweeds with ascertained therapeutic activity. With specific reference, astaxanthin is widely used in clinical practice to improve ocular tissue health and skin protection from UV ray damages. Despite its well-documented pleiotropic actions and demonstrated clinical efficacy, its bioavailability in humans is low and limited because of its hydrophobicity and poor dissolution in enteric fluids. Furthermore, astaxanthin is very unstable molecule and very sensitive to light exposure and thermal stress. Taken together, these pharmacological and chemical\u2013physical features strongly limit pharmaceutical and nutraceutical development of astaxanthin-based products and as a consequence its full clinical usage. This work describes the preliminary in vitro investigation of sublingual absorption of astaxanthin through a novel ascorbyl palmitate (ASP) based nanoemulsion

    Secondo alcune recenti indagini gli studenti del XXI secolo, pur avendo familiarità con le tecnologie, non possono essere definiti digital learnes, ovvero studenti che utilizzano la tecnologia anche per la formazione, e in particolare essi prediligono l’utilizzo di materiali cartacei per lo studio delle lingue. Con il presente contributo si intende fornire un ulteriore aggiornamento del profilo digitale degli studenti universitari stranieri confrontandolo con quello di studenti universitari italiani, al fine di verificare eventuali variazioni dipendenti sia dalla variabile tempo sia dall’ulteriore diffusione delle tecnologie nel campo della formazione. In generale i risultati emersi dal presente studio, pur rilevando una maggiore permeabilità della tecnologia nel settore della formazione linguistica, confermano la preferenza del tipo di supporti tradizionali e sono anche in linea con diversi studi di tipo cognitivo relativi alla comprensione del testo e ai supporti digitali secondo i quali gli apprendenti, indipendentemente dall’età, e anche dalla nazionalità, per il loro studio preferiscono l’utilizzo di supporti cartacei. Italian l2 study materials preferences: paper or digital? According to some recent surveys, although students in the 21st century are familiar with technology, they cannot be defined as digital learners, i.e. students who also use technology for studying, and in particular they prefer using paper materials to study languages. The purpose of this contribution is to provide a further update of the digital profile of foreign university students in comparison to Italian university students, in order to verify possible differences depending on both the time variable and the further spread of technology in the field of education. In general, the results of this study, while noting a greater presence of technology in the field of language training, confirm the preference for traditional media,. This is in line with several cognitive studies related to the understanding of texts and digital media according to which learners, regardless of age, and nationality, prefer the use of paper resources to study language

    Scopo della presente ricerca \ue8 testare la validit\ue0 dell\u2019Ipotesi del Mapping Lessicale della Teoria della Processabilit\ue0 per l\u2019italiano L2 secondo la recente formulazione (Pienemann, Di Biase, Kawaguchi 2005; Bettoni, Di Biase in stampa). In particolare verr\ue0 verificata l\u2019implicazionalit\ue0 dei tre stadi dell\u2019Ipotesi del Mapping Lessicale, focalizzando successivamente l\u2019attenzione sul terzo stadio dello sviluppo sintattico, lo stadio della mappatura non di default (NDF). In questo stadio la ricerca si concentrer\ue0 nello studio delle \uabcostruzioni con il si\ubb che richiedono mappature non canoniche. Partendo dalla descrizione dei verbi e delle costruzioni con il si secondo le tre strutture di rappresentazione della frase (struttura argomentale, struttura funzionale e struttura dei costituenti) formulate dalla Grammatica Lessico Funzionale (Bresnan 2001; Dalrymple 2001; Falk 2001), si proceder\ue0 nella classificazione degli stessi sulla base del tipo di mappature richieste (canoniche vs non canoniche). Lo studio \ue8 basato su un corpus learner di italiano L2 di 24 apprendenti adulti con varie L1. Con il presente lavoro si mostrer\ue0 come, a causa della diversa natura delle costruzioni con il si, l\u2019acquisizione delle stesse non avvenga\ua0 in modo uniforme e contemporaneo, ma segua una sequenza di acquisizione determinata da elementi che riguardano la natura degli argomenti del predicato verbale e la loro mappatura sulle funzioni grammaticali e che interessano anche il piano pragmatico di tali costruzioni.This research paper aims to test the plausibility of the Lexical Mapping Hypothesis of Processability Theory for Italian L2 according to its recent formulation (Pienemann, Di Biase, Kawaguchi 2005; Bettoni, Di Biase in press). In particular, we will test the implicationality of the three stages of the Lexical Mapping Hypothesis, later focusing our attention on the third stage of syntactic development, the stage of non-default mapping (NDF). For this stage, the research will focus on the study of \uabsi-constructions\ubb that require non-canonical mapping. Starting from the description of \uabsi-constructions\ubb according to the three structures of sentence representation (argument structure, functional structure and constituent structure) set out by Lexicon Functional Grammar (Bresnan 2001; Dalrymple 2001; Falk 2001), we will then proceed upon their classification on the basis of the type of mapping required (canonical vs non-canonical). The study is based on a corpus of Italian L2 learners made up of 24 adult learners with various L1s. With this paper we will demonstrate how the acquisition of the \uabsi-constructions\ubb does not happen in a uniform and simultaneous manner, but follows a sequence of acquisition determined by factors that relate to the nature of the topics of the verbal predicate and their mapping onto grammatical functions, and that also affect the pragmatic level of such constructions

    LE LIFE SKILLS NEL VOLUME COMPLEMENTARE DEL QCER

    Il presente contributo focalizza l’attenzione sulla dimensione relazionale e interpersonale dell’apprendimento linguistico attraverso una lettura di tipo trasversale dei descrittori di Mediazione del Volume complementare del QCER (2020). Un’attenta analisi dei descrittori “Mediare a livello concettuale” e “Mediare a livello comunicativo” ha permesso di evidenziare come in essi si faccia riferimento a competenze non solo strettamente linguistiche ma anche a competenze piĂą generali, le life skills, come illustrato nel documento dell’Organizzazione Mondiale della Salute Life Skills Education for children and adolescents in Schools (OMS, 1997). «Assumere diversi ruoli in funzione dei bisogni dei partecipanti», come recita uno dei descrittori di mediazione del QCER Volume complementare (2020: 121), implica anche che gli apprendenti siano in grado di usare la lingua in modo efficace in relazione al ruolo da loro assunto in contesti sociali differenti. Usare la lingua efficacemente chiama in causa una competenza piĂą ampia che riguarda la capacitĂ  di usare una comunicazione efficace (effective communication), e sapere usare una comunicazione efficace è anche una delle dieci life skills richieste dall’OMS (1997). Dunque, passando dai descrittori del QCER Volume complementare e alle life skills del documento dell’OMS, nel presente contributo si farĂ  riferimento ad alcuni possibili percorsi trasversali che danno il giusto peso alla formazione linguistica nella sua dimensione piĂą ampia del termine.   Life skills in the CEFR Companion volume This paper focuses on the relational and interpersonal dimension of language learning through a transversal reading of the CEFR Companion volume (2020). A careful analysis of the “Mediating concepts” and “Mediating communication” underlying the new descriptors highlights how they are not limited to language skills, but also include more general skills, namely life skills. These are set out in the Document by the World Health Organization entitled Life Skills Education for children and adolescents in Schools (WHO, 1997). One of the objectives of mediation in the CEFR Companion volume descriptors (2020: 121) is the ability to assume different roles corresponding to individual needs within a given social context. They require that learners be able to use the language effectively in different social contexts. Using language effectively underlies the need for boosting overall communication ability,  one of the ten life skills set out in the WHO document (1997). Starting from the CEFR Companion volume descriptors and Life Skills in the WHO document, this contribution will refer to interconnecting paths that give due weight to language training in the broadest sense

    Una proposta per integrare autovalutazione e valutazione in entrata dell'italiano L2 rivolta a studenti universitari stranieri in scambio con l'UniversitĂ  di Padova

    The project aims to present the results of an experimental research study conducted during the academic years 2015-2016, 2016-2017 at the University of Padova Language Centre (CLA). The objectives of this study are to examine the results of the proposal to integrate self-evaluation and entrance evaluation aimed at foreign incoming students enrolled at our University. In the first phase an initial review of the placement test results carried out at the CLA combined with an examination of language certificates presented by the students has raised some critical issues related to incongruous data among the various tests/certifications. Other situations have shown different results regarding language skills within the same test, which has reinforced the decision to also introduce a system of self-assessment to grant greater autonomy and responsibility to the students when choosing their class. To this end, in the second phase, two different self-assessment tools have been assigned to the students with the attempt to answer the questions whether students can be good "self-assessors" and if self-assessment tools based on Common European Framework of Reference (CEFR) "can do" descriptors and on the Syllabus adopted in our language Centre can be used as reliable diagnostic tools in an academic environment in which learners are expected to have some experience with self-rating. The results have shown that the self-assessment instruments we used may function as a placement tools, but that this is true especially in the case of learners who are familiar with self-assessment and with the teacher's guidance. The third phase, described in detail in this contribution, is to overcome the previously emerging critical issues by providing an interactive guided syllabus, since it effectively integrates evaluation and self-assessment and actively engages the student in choosing the proper language level through online activities

    ComposizionalitĂ  delle 'locuzioni congiuntive' con significato finale: tedesco, francese e italiano a confronto

    Get PDF
    ENThis paper presents a comparative analysis of the compositionality of the conjunctive phrases that introduce final clauses in German, French and Italian, a phenomenon that is seldom described in dictionaries and traditional grammars. Based on several fundamental studies on conjunctive phrases of purpose in the abovementioned languages, the phenomenon in question is first defined and then several representative examples of conjunctive phrases belonging to semantic classes that express purpose are described. This description highlights the fact that in German, French and Italian, the conjunctive phrases of purpose are free structures, as the complex sentences in which they occur can be restructured, largely analogously in the three compared languages, when their complex sentences of origin have equally similar structures. In this case, the applicability of the transformations to the constructions considered is based on the possibility of actualizing the nominal predicate present in the conjunctive phrase by means of verbs that maintain the predicative value of the noun within the phrase, which therefore turns out to be a sentence reduction. Keywords: 1. relationships of purpose; 2. conjunctive phrases, 3. nominal predicates, 4. semantic classes; 5. transformations. ITIn questo contributo si illustra a livello comparativo, con riferimento al tedesco, al francese e all'italiano, la composizionalità delle “locuzioni congiuntive” che introducono frasi finali, fenomeno sostanzialmente non descritto nelle grammatiche tradizionali e nei dizionari. Sulla base di alcuni studi fondamentali esistenti sulle locuzioni congiuntive con significato finale nelle lingue sunnominate, si definisce dapprima il fenomeno in oggetto e successivamente si descrivono alcune occorrenze rappresentative di locuzioni congiuntive appartenenti alle classi semantiche che esprimono la finalità. La descrizione metterà in luce che le locuzioni congiuntive con valore finale del tedesco, del francese e dell'italiano sono strutture libere, in quanto le frasi complesse in cui esse occorrono sono passibili di ristrutturazioni, per lo più analoghe nelle tre lingue comparate, quando le frasi complesse originarie hanno del pari struttura simile. Nella fattispecie, l'applicabilità delle trasformazioni ai costrutti considerati si basa sulla possibilità di attualizzare il predicato nominale presente nella locuzione congiuntiva originaria tramite verbi che mantengono il valore predicativo del nome presente nella locuzione, la quale risulta quindi una riduzione di frase. Parole chiave: 1. locuzioni congiuntive; 2. trasformazioni; 3. predicato nominale ; 4. finalità; 5 classi semantich

    INSEGNAMENTO LINGUISTICO ED EMERGENZA SANITARIA: RIFLESSIONI SULLA DAD

    Get PDF
    La prima fase di emergenza sanitaria determinata dal COVID-19 ha avuto come effetto l’avvio esteso di pratiche di didattica a distanza (DAD) nel settore educativo a ogni grado di istruzione e di formazione. Durante questa fase i docenti hanno avuto l’opportunitĂ  di confrontarsi, in modo piĂą o meno consapevole, con ambienti di apprendimento non sempre familiari, affinando o sperimentando in alcuni casi per la prima volta approcci e-learning focalizzati sull’uso di risorse digitali per l’apprendimento a distanza. Il presente lavoro intende proporre alcune riflessioni sull’insegnamento dell'Italiano L2 online, maturate dall’analisi dei dati di un questionario elaborato attraverso lo strumento Moduli di Google Suite e somministrato online nel mese di maggio 2020 a docenti con profili professionali diversificati. L’esame delle risposte ai quesiti del questionario ha restituito informazioni quantitative e qualitative su atteggiamenti e comportamenti degli insegnanti. Tali informazioni sono state trattate nel contributo focalizzando l’attenzione su tre macroaree di interesse: modalitĂ  di interazione online e gestione della classe “virtuale”, formazione degli insegnanti e approcci adottati nell’e-learning, pratiche tradizionali e nuove modalitĂ  di valutazione.   Language teaching and the health emergency: reflections on DL The first phase of the COVID-19 health emergency had a widespread effect on the start of distance learning practices (DL) in the educational sector at every level of education and on training. During this phase, teachers had the opportunity to deal, more or less consciously, with learning environments that were not always familiar, refining or experimenting in some cases for the first time with e-learning approaches focused on the use of digital resources for distance learning. The aim of this work is to offer some reflections on the teaching of Italian L2 online. These reflections are based on the analysis of data from a questionnaire developed using the Google Suite Modules tool, and conducted online in May 2020 with teachers with different professional profiles. The answers to the questionnaire returned quantitative and qualitative information on teacher attitudes and behaviors. This information presented in the article focuses on three macro areas of interest: online interaction methods and “virtual” classroom management, teacher training and e-learning approaches, traditional practices and new evaluation methods

    This paper offers an opportunity to reflect on developing new skills and competences to respond to the new challenges and transformations posed by changes in the world of education and training in our knowledge-based society. In particular, the paper aims at analysing and reflecting on the so-called 'transversal key competences' and their application to Italian L2 teaching in universities. These skills and competences are needed to succeed in an ever-changing world not only to support the development of language skills, but also to promote personal development, employability, mobility and active citizenship
