Analytics dei testi riflessivi scritti dai docenti neoassunti nel portfolio digitale

In this paper, we present the preliminary results of the analysis performed on 50,000texts written by the Newly Qualified Teachers to reflect on their practice. The Italian InductionProgramme for NQT includes online activities to be carried out in the E-portfoliomanaged by Indire. As part of the training monitoring with the aim to evaluate our supportand to improve instructional scaffolding to teachers, we analysed teachers’ reflectivewriting mixing a new developed framework for teachers’ reflective writing andNatural Language Processing (NLP) techniques. In providing a case study of a large-scaleanalysis of textual teachers’ data in an institutional setting, this paper wants to contributeto the field of learning analytics. We will describe the context, the characteristics of thedata analysed, how all of this has shaped the analytics design. We will describe its implementationand therefore the procedures, tools and metrics developed to representthe content of the teachers’ reflective writing, and we will try to evaluate if and howthese preliminary results can help us to reach the research goals and to understand thestrengths and weaknesses of different methodologies.Presentiamo i risultati preliminari e l’analisi svolta su circa 50.000 testi scritti dai docentineo nominati in ruolo per riflettere su due attività didattiche svolte con gli studenti, nelcontesto del percorso dell’anno di formazione e prova 2016/17. Il percorso prevede attivitàin presenza e attività a distanza completate sul portfolio digitale, ospitato nell’ambienteonline gestito dall’Indire. Nell’ambito del monitoraggio della formazione, con il fine di ottimizzaregli strumenti e il supporto fornito, abbiamo interrogato i dati testuali prodottidai docenti nell’interazione con l’ambiente per capire se i testi presentassero evidenze riconducibilialle scritture riflessive. Obiettivi dell’indagine sono stati la definizione di unoschema per la classificazione dei testi sulla base del livello di riflessività evidenziato e l’impiego di strumenti di Trattamento Automatico del Linguaggio (TAL) per l’analisi dell’interocorpus testuale prodotto dai docenti. Descriveremo il contesto scientifico e progettuale,le caratteristiche dei dati analizzati, come questo abbia determinato il disegno d’indagine;descriveremo inoltre la sua implementazione e dunque le procedure, gli strumenti e lemetriche adottate o elaborate per rappresentare il contenuto dei dati; infine discuteremoi primi risultati e alcuni vantaggi e limiti dell’approccio adottato

Proceedings of the Fifth Italian Conference on Computational Linguistics CLiC-it 2018

On behalf of the Program Committee, a very warm welcome to the Fifth Italian Conference on Computational Linguistics (CLiC-­‐it 2018). This edition of the conference is held in Torino. The conference is locally organised by the University of Torino and hosted into its prestigious main lecture hall “Cavallerizza Reale”. The CLiC-­‐it conference series is an initiative of the Italian Association for Computational Linguistics (AILC) which, after five years of activity, has clearly established itself as the premier national forum for research and development in the fields of Computational Linguistics and Natural Language Processing, where leading researchers and practitioners from academia and industry meet to share their research results, experiences, and challenges

Studio linguistico-computazionale sulla persuasione: il caso dei discorsi politici e delle recensioni online

Il presente lavoro indaga le caratteristiche linguistiche che caratterizzano fenomeni persuasivi all’interno di un corpus di discorsi politici in inglese annotati con le reazioni del pubblico (quali applausi e risate) e uno di recensioni in italiano estratte da un portale di viaggi online insieme ai voti di utilità ottenuti dagli altri utenti. In particolare, ci si concentra sul ruolo di un ampio spettro di caratteristiche volte a modellare la “forma” del testo e sul loro impatto su compiti di classificazione rispetto a caratteristiche tradizionalmente impiegate per modellarne il contenuto. Gli esperimenti sono stati condotti in scenari cross-domain, che coinvolgono nella fase di valutazione domini progressivamente più lontani da quello di addestramento, in modo da verificare se le caratteristiche linguistiche che contraddistinguono i testi persuasivi (quelli in grado di suscitare applausi e risate oppure ottenere voti dagli utenti) siano generalizzabili anche a testi diversi per il contenuto

Real-World Use and Predictors of Response to Disopyramide in Patients with Obstructive Hypertrophic Cardiomyopathy

Background: Although disopyramide has been widely used to reduce left ventricular outflow obstruction (LVOTO) and to improve symptoms in patients with obstructive hypertrophic cardiomyopathy (oHCM), its use in real world as well as patient characteristics associated with a positive treatment response are still unclear. Methods: From 1980 to 2021, 1527 patients with HCM were evaluated and 372 (23%) had a LVOTO with active follow-up. The efficacy and safety of disopyramide were assessed systematically during 12 months (2-, 6-, and 12-month visits). Responders were patients with a final NYHA = I and a LVOTO I and a LVOTO 30 mmHg. Results: Two-hundred-fifty-four (66%) patients were in functional class NYHA I/II and 118 (34%) in NYHA III/IV. A total of 118/372 (32%, 55 ± 16 years) underwent disopyramide therapy. Twenty-eight (24%) patients responded to therapy, 39 (33%) were incomplete responders, and 51 (43%) did not respond. Responder were mainly patients in functional NYHA class I/II (24/28, 86%), whereas incomplete responders and non-responders were more often in functional NYHA class III/IV (50/54 (93%)). An independent predictor of response to disopyramide treatment was the presence of NYHA I/II at the initiation of therapy (HR 1.5 (95% CI 1.1–4.5), p = 0.03). No major life-threatening arrhythmic events or syncope occurred, despite 19 (16%) patients showing reduced QTc from baseline, 19 (16%) having no difference, while 80 (69%) patients had prolonged QTc interval. Thirty-one (26%) patients experienced side effects, in particular, 29 of the anticholinergic type. Conclusions: Disopyramide was underused in oHCM but effective in reducing LVOTO gradients and symptoms in slightly symptomatic patients with less severe disease phenotype with a safe pro-arrhythmic profile

MEDICAL SCIENCE. GISSI-2: A factorial randomised trial of alteplase versus streptokinase and heparin versus no heparin among 12 490 patients with acute myocardial infarction

A multicentre, randomised, open trial with a 2 x 2 factorial design was conducted to compare the benefits and risks of two thrombolytic agents, streptokinase (SK, 1\ub75 MU infused intravenously over 30-60 min) and alteplase (tPA, 100 mg infused intravenously over 3 h) in patients with acute myocardial infarction admitted to coronary care units within 6 h from onset of symptoms. The patients were also randomised to receive heparin (12 500 U subcutaneously twice daily until discharge from hospital, starting 12 h after beginning the tPA or SK infusion) or usual therapy. All patients without specific contraindications were given atenolol (5-10 mg iv) and aspirin (300-325 mg a day). The end-point of the study was the combined estimate of death plus severe left ventricular damage. 12 490 patients were randomised to four treatment groups (SK alone, SK plus heparin, tPA alone, tPA plus heparin). No specific differences between the two thrombolytic agents were detected as regards the combined end-point (tPA 23\ub71%; SK 22\ub75%; relative risk 1\ub704, 95% Cl 0\ub795-1\ub713), nor after the addition of heparin to the aspirin treatment (hep 22\ub77%, no hep 22\ub79%; RR 0\ub799, 95% Cl 0\ub791-1\ub708). The outcome of patients allocated to the four treatment groups was similar with respect to baseline risk factors such as age, Killip class, hours from onset of symptoms, and site and type of infarct. The rates of major in-hospital cardiac complications (reinfarction, post-infarction angina) were also similar. The incidence of major bleeds was significantly higher in SK and heparin treated patients (respectively, tPA 0\ub75%, SK 1\ub70%, RR 0\ub757, 95% Cl 0\ub738-0\ub785; hep 1\ub70%, no hep 0\ub76%, RR 1\ub764, 95% Cl 1\ub709-2\ub745), whereas the overall incidence of stroke was similar in all groups. SK and tPA appear equally effective and safe for use in routine conditions of care, in all infarct patients who have no contraindications, with or without post-thrombolytic heparin treatment. The 8\ub78% hospital mortality of the study population (compared with approximately 13% in the control cohort of the GISSI-1 trial) indicates the beneficial impact of the proven acute treatments for AMI. \ua9 1990
