An Integrated Solution among Social, Personal and Formal Learning for Lifelong Competences

In the Knowledge Society the worker should benefit from learning experiences which intersect formal learning moments with both individual and collaborative informal learning, according to a vision of authentic lifelong edu-cation” The paper suggests an innovative answer to the “lifelong competence” management approach. In this context a Lifelong Learning Model (LLM) finds its realization through an integrated solution among the personal, social and formal learning. The vision is sustained by a conceptual architecture, which represents a distinctive and enabling factor for the management of competence allowing to customize training paths on the worker profile. The idea is related to the integration between a Personal Learning Environment (PLE), a learning community and the solution of the Polo di Eccellenza L&K, the learning plat-form IWT (Intelligent Web Teacher)

Personalization and Contextualization of Learning Experiences based on Semantics

Context-aware e-learning is an educational model that foresees the selection of learning resources to make the e-learning content more relevant and suitable for the learner in his/her situation. The purpose of this paper is to demonstrate that an ontological approach can be used to define leaning contexts and to allow contextualizing learning experiences finding out relevant topics for each context. To do that, we defined a context model able to formally describe a learning context, an ontology-based model enabling the representation of a teaching domain (including context information) and a methodology to generate personalized and context-aware learning experiences starting from them. Based on these theoretical components we improved an existing system for personalized e-learning with contextualisation features and experimented it with real users in two University courses. The results obtained from this experimentation have been compared with those achieved by similar systems

"Classi in rete". Un modello internazionale per innovare la didattica nelle piccole scuole.

L’apprendimento a distanza rappresenta un grande potenziale per le piccole scuole, richiede però di ripensare la forme scolaire per queste ultime. Indire, in collaborazione con il Centre scolaire du Fleuve et des Lacs (Ministère de l’éducation et de l’enseignement supérieur du Québec), la Italian University Line (IUL), l’Ufficio Scolastico Regionale (USR) Abruzzo e un esperto dell’Università della Valle d’Aosta, ha promosso un intervento di formazione e sperimentazione per aiutare i docenti delle piccole scuole ad attuare il modello “Classi in rete” sviluppato dall’École éloignée en Réseau (Allaire et al., 2009) e basato sull’approccio teorico delle Knowledge Building Communities

A Cultural Re-mediation Model for Storytelling in Pre-school Education

The use of the emotional language of stories and the amplification of the empathic driver thanks to the identification with story characters, makes the storytelling a valuable educational approach, especially for children. In accordance with embodied and situated cognition theories, manipulative storytelling proposes interactive environments where it is also possible for learners to manipulate the story through objects and tangible interfaces. In line with this vision, we propose in this paper a new model enabling the design and the execution of educational stories for children aged from 3 to 6. Stories are seen as sequences of missions: game experiences where children can interact to reach the educational objective. A re-mediation strategy, able to adapt the story on three different axis (immediacy-hypermediation, similarity-dissimilarity and aggregation-disaggregation) on the basis of assessment results, is also presented. A proof of concept based on the popular Brother Grimm's Hansel and Gretel tale is then discussed to demonstrate the capabilities of the model in the construction and deconstruction of the building blocks of a story

CMR T2* Technique for Segmental and Global Quantification of Myocardial Iron: Multicentre Transferability and Healthcare Impact Evaluation

The multislice multiecho T2* technique is transferable among scanners with good reproducibility. The network seems to be a robust and scalable system in which T2* CMR based cardiac iron overload assessment is available, accessible and reachable for a significant and increasing number of thalassemia patients, reducing the mean distance from the patients\u27 locations to the CMR sites

Antibiotic use among 8-month-old children in Malmö, Sweden – in relation to child characteristics and parental sociodemographic, psychosocial and lifestyle factors

In the county of Scania, Sweden, antibiotic use among small children is among the highest in the country. The aim of this study was to investigate the associations between antibiotic use among 8-month-old children in Malmö and characteristics of the child as well as parental sociodemographic characteristics, lifestyle factors, and psychosocial support. The study was a population-based cross-sectional survey. The study population consisted of children who visited the Child Health Care (CHC) centres in Malmö for their 8-month health checkup during 2003–2006 and whose parents answered a self-administered questionnaire (n = 7266 children). The questionnaire was distributed to parents of children registered with the CHC and invited for an 8-month checkup during the study period. The odds of using antibiotics increased as parental educational level decreased. Using high educational level as a reference group, low maternal educational level was associated with an increased antibiotic use for the child, odds ratio (OR) = 1.61 (95% CI: 1.34–1.93). Furthermore, children whose parents were born outside Sweden showed higher antibiotic use, OR = 1.43 (95% CI: 1.24–1.65), in comparison with children whose parents were born in Sweden. Exposure to environmental smoking, parental experience of economic stress, and a low level of emotional support increased the odds for antibiotic use. Boys had higher odds of use of antibiotics than girls, OR = 1.40 (95% CI: 1.25–1.57). Having a low birth weight, having an allergy and having siblings also increased the odds for early antibiotic use, while breastfeeding seemed to have a protective role. Conclusion There were clear associations between parental factors such as sociodemographic, psychosocial and lifestyle factors and antibiotic use at this early stage of life. Several characteristics of the child also affected the use of antibiotics

Quality of Reporting and Study Design of CKD Cohort Studies Assessing Mortality in the Elderly Before and After STROBE:A Systematic Review

BACKGROUND:The STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement was published in October 2007 to improve quality of reporting of observational studies. The aim of this review was to assess the impact of the STROBE statement on observational study reporting and study design quality in the nephrology literature. STUDY DESIGN:Systematic literature review. SETTING & POPULATION:European and North American, Pre-dialysis Chronic Kidney Disease (CKD) cohort studies. SELECTION CRITERIA FOR STUDIES:Studies assessing the association between CKD and mortality in the elderly (>65 years) published from 1st January 2002 to 31st December 2013 were included, following systematic searching of MEDLINE & EMBASE. PREDICTOR:Time period before and after the publication of the STROBE statement. OUTCOME:Quality of study reporting using the STROBE statement and quality of study design using the Newcastle Ottawa Scale (NOS), Scottish Intercollegiate Guidelines Network (SIGN) and Critical Appraisal Skills Programme (CASP) tools. RESULTS:37 papers (11 Pre & 26 Post STROBE) were identified from 3621 potential articles. Only four of the 22 STROBE items and their sub-criteria (objectives reporting, choice of quantitative groups and description of and carrying out sensitivity analysis) showed improvements, with the majority of items showing little change between the period before and after publication of the STROBE statement. Pre- and post-period analysis revealed a Manuscript STROBE score increase (median score 77.8% (Inter-quartile range [IQR], 64.7-82.0) vs 83% (IQR, 78.4-84.9, p = 0.05). There was no change in quality of study design with identical median scores in the two periods for NOS (Manuscript NOS score 88.9), SIGN (Manuscript SIGN score 83.3) and CASP (Manuscript CASP score 91.7) tools. LIMITATIONS:Only 37 Studies from Europe and North America were included from one medical specialty. Assessment of study design largely reliant on good reporting. CONCLUSIONS:This study highlights continuing deficiencies in the reporting of STROBE items and their sub-criteria in cohort studies in nephrology. There was weak evidence of improvement in the overall reporting quality, with no improvement in methodological quality of CKD cohort studies between the period before and after publication of the STROBE statement

Multicentre multi-device hybrid imaging study of coronary artery disease: results from the EValuation of INtegrated Cardiac Imaging for the Detection and Characterization of Ischaemic Heart Disease (EVINCI) hybrid imaging population

AIMS: Hybrid imaging provides a non-invasive assessment of coronary anatomy and myocardial perfusion. We sought to evaluate the added clinical value of hybrid imaging in a multi-centre multi-vendor setting. METHODS AND RESULTS: Fourteen centres enrolled 252 patients with stable angina and intermediate (20-90%) pre-test likelihood of coronary artery disease (CAD) who underwent myocardial perfusion scintigraphy (MPS), CT coronary angiography (CTCA), and quantitative coronary angiography (QCA) with fractional flow reserve (FFR). Hybrid MPS/CTCA images were obtained by 3D image fusion. Blinded core-lab analyses were performed for CTCA, MPS, QCA and hybrid datasets. Hemodynamically significant CAD was ruled-in non-invasively in the presence of a matched finding (myocardial perfusion defect co-localized with stenosed coronary artery) and ruled-out with normal findings (both CTCA and MPS normal). Overall prevalence of significant CAD on QCA (>70% stenosis or 30-70% with FFR 640.80) was 37%. Of 1004 pathological myocardial segments on MPS, 246 (25%) were reclassified from their standard coronary distribution to another territory by hybrid imaging. In this respect, in 45/252 (18%) patients, hybrid imaging reassigned an entire perfusion defect to another coronary territory, changing the final diagnosis in 42% of the cases. Hybrid imaging allowed non-invasive CAD rule-out in 41%, and rule-in in 24% of patients, with a negative and positive predictive value of 88% and 87%, respectively. CONCLUSION: In patients at intermediate risk of CAD, hybrid imaging allows non-invasive co-localization of myocardial perfusion defects and subtending coronary arteries, impacting clinical decision-making in almost one every five subjects
