Online education based on small self‐managing groups, with slight supervision by a professional tutor, is a strategically interesting methodology for lifelong learning. This solution may combine aspects of cost‐effectiveness (reducing tutors' work) with the demands for active and engaging learning methods based on the exchange and sharing of experiences. In such a context, how can information on collaborative attitudes and behaviour be gathered? A typical tool for online learning activities is the threaded web forum. This study proposes a methodology for assessing effective collaborative interactions within the add‐on module, Forum Plus, for the Moodle learning management system (LMS). The methodology here presented is able to supply an early overview of the level of effectiveness of the collaborative group and therefore it may provide a useful instrument to guide further qualitative observations conducted directly in the web forum. 相似文献

ABSTRACTThe church of San Diego de Alcalá, located in Pitiquito, Sonora , in Mexico, lies on a missionary road founded by the Jesuit Eusebio F. Kino, which, with the expulsion of the Jesuit order in 1767, passed into the care of the Franciscans. It contains wallpaintings which presented deterioration problems whose cause was not easy to determine, since the damage appeared to be inconsistent with the techniques used and the environmental conditions. With an interdisciplinary team, a methodology was designed for a combined study of the environment of the church and its wallpaintings. Thermal imaging of the exterior and interior walls indicated that the building was made up of different materials, and the junctions between them explained the different deterioration pathologies between one zone and another. Hydrological maps for groundwater in the locality were studied, to elucidate the presence of water in a desert zone; abundant sources of water in the subsoil were identified, which, because of overexploitation of the land, have been diminishing over time. This allowed the elaboration of a plan for site management, through the identification of those deterioration factors that can be mitigated by simple maintenance actions that are inherent to the environment and the materials, which enabled a scheduled maintenance scheme to be implemented. This improved the condition of the building and its wallpaintings, while reducing the resource invested to achieve this goal. 相似文献

This article explores the role of voluntary quality assessments in higher education, underscoring their main features and potentialities, and showing that basic principles and guidelines can be customised in different countries or single institutions. The article extensively presents an assessment project developed at the University of Siena, the first integrated assessment of teaching and research quality of a whole university carried out in Italy. The article clearly highlights the relevance of quality assurance and performance measurement systems and the behavioural and organisational impacts they may have. 相似文献

IntroductionSeveral laboratory tests are characteristically altered in Coronavirus Disease 2019 (COVID-19), but are not totally accurate in predicting the disease outcome. The long pentraxin 3 (PTX3) is quickly released directly at inflammation sites by many immune cell types. Previous studies have shown that PTX3 correlated with disease severity in various inflammatory conditions. Our study investigated the use of PTX3 as a potential marker of COVID-19 severity and compared its performance in detecting a more severe form of the disease with that of routine laboratory parameters.Materials and methodsStored serum samples of RT-PCR confirmed COVID-19 cases that had been obtained at hospital admission were retrospectively analysed. Intensive care unit (ICU) stay was considered a surrogate endpoint of severe COVID-19. Pentraxin 3 was measured by a commercial enzyme-linked immunosorbent assay.ResultsA total of 96 patients were recruited from May 1st, 2020 to June 30th, 2020; 75/96 were transferred to ICU. Pentraxin 3 was higher in ICU vs non-ICU patients (35.86 vs 10.61 ng/mL, P < 0.001). Univariate and multivariate logistic regression models demonstrated that the only significant laboratory predictor of ICU stay was PTX3 (OR: 1.68 (1.19-2.29), P = 0.003), after controlling for comorbidities. The Receiver Operator Characteristic curve analysis showed that PTX3 had a higher accuracy compared to C-reactive protein (CRP), lactate dehydrogenase (LD), ferritin in identifying ICU patients (AUC of PTX3 = 0.98; CRP = 0.66; LD = 0.70; ferritin = 0.67, P < 0.001). A cut-off of PTX3 > 18 ng/mL yielded a sensitivity of 96% and a specificity of 100% in identifying patients requiring ICU.ConclusionHigh values of PTX3 predict a more severe COVID-19. 相似文献

Developing oral presentation skills requires both practice and expert feedback. Several systems have been developed during the last 20 years to provide ample practice opportunities and automated feedback for novice presenters. However, a comprehensive literature review discovered that none of those systems have been adequately evaluated in real learning settings. This work is the first randomised controlled evaluation of the impact that one of these systems has in developing oral presentation skills during a real semester-long learning activity with 180 students. The main findings are that (1) the development of different dimensions of the oral presentations are not affected equally by the automated feedback and (2) there is a small but statistically significant effect of the use of the tool when a subsequent presentation is evaluated by a human expert. 相似文献

Who are the NEET? How much do we know about this? What do institutions and the media know about them? How different definitions could get to shared policies? This paper tries to provide an initial overview of the situation regarding the NEET, through an analysis of the emerging international literature on the subject. Different definitions across nations are analyzed in order to reflect on the cultural differences and economics-work policies, in order to then analyze more in deep the Italian situation. In Italy, the phenomenon is still little known in society and, often, not recognized by the acronym NEET, with the many variables that define it, despite statistics showing a rise in numbers (26 % of the total population for the age group considered). 相似文献

The paper reports a case study where a relatively lightweight technology in the form of a Web-based questionnaire was used to support members of a real community of professionals in externalizing and sharing their good practices and achieving a better awareness of and agreement on topics of common interest. We focused on an important medical association that counts more 1000 doctors all around the world as its members. In particular, we report how this association used the occasion of the on-line survey enabled by our technology to increase the awareness of its members about the actual heterogeneity of preferences existing in their daily clinical practice, and to trigger discussion toward a better consensus on best practices, appropriate indications, and treatments of choice for their profession and practice. We also report the result of a post-hoc evaluation of the Web-based technology employed, and draw some implications for the better design of this kind of tool in order to collect and share collective knowledge in specific professional domains. 相似文献

Governments worldwide are encouraging public agencies to join e-Government initiatives in order to provide better services to their citizens and businesses; hence, methods of evaluating the readiness of individual public agencies to execute specific e-Government programs and directives are a key ingredient in the successful expansion of e-Government. To satisfy this need, a model called the eGovernment Maturity Model (eGov-MM) was developed, integrating the assessment of technological, organizational, operational, and human capital capabilities, under a multi-dimensional, holistic, and evolutionary approach. The model is strongly supported by international best practices, and provides tuning mechanisms to enable its alignment with nation-wide directives on e-Government. This article describes how the model was conceived, designed, developed, field tested by expert public officials from several government agencies, and finally applied to a selection of 30 public agencies in Chile, generating the first formal measurements, assessments, and rankings of their readiness for e-Government. The implementation of the model also provided several recommendations to policymakers at the national and agency levels. 相似文献
