“Il nostro impegno consiste nel portare la scuola del Novecento in questo secolo. Ciò significa saper innovare contenuti e metodi senza stravolgere un modello educativo che funziona e che ha prodotto eccellenze nei secoli, da Galileo a Fabiola Gianotti. Perciò non intendiamo sostituire il modello knowledge-based su cui si fonda la scuola italiana con il modello skill-based più tipico del mondo anglosassone. Il nostro obiettivo è di sviluppare nuove competenze e nuove abilità pratiche, sulla base di una solida conoscenza teorica”. Così afferma il Ministro Stefania Giannini in una intervista con Armando Massarenti pubblicata il 22 febbraio 2015 su “Il Sole 24 ore”. Con tatto e al tempo stesso con ferma decisione, Giannini pone una questione di fondo per lo sviluppo economico e culturale del nostro Sistema-Paese: se è vero che l’educazione scolastica (e universitaria) in Italia è basata sulla trasmissione di conoscenze, è altresì fondamentale riconoscere come la trasmissione di conoscenze non basta più, da sola, per formare il personale oggi necessario a sostenere nel lungo periodo la competitività delle aziende e, più in generale, di tutte quelle organizzazioni (Istituzioni, Terzo settore etc.), dove prendono corpo i processi di creazione di valore. Ciò che urge sempre di più, in un mercato del lavoro dove la flessibilità è metodo, è un personale dotato di competenze trasversali, ovvero di competenze che hanno una base metacognitiva, più che cognitiva

Caching Historical Embeddings in Conversational Search

Rapid response, namely low latency, is fundamental in search applications; it is particularly so in interactive search sessions, such as those encountered in conversational settings. An observation with a potential to reduce latency asserts that conversational queries exhibit a temporal locality in the lists of documents retrieved. Motivated by this observation, we propose and evaluate a client-side document embedding cache, improving the responsiveness of conversational search systems. By leveraging state-of-the-art dense retrieval models to abstract document and query semantics, we cache the embeddings of documents retrieved for a topic introduced in the conversation, as they are likely relevant to successive queries. Our document embedding cache implements an efficient metric index, answering nearest-neighbor similarity queries by estimating the approximate result sets returned. We demonstrate the efficiency achieved using our cache via reproducible experiments based on TREC CAsT datasets, achieving a hit rate of up to 75% without degrading answer quality. Our achieved high cache hit rates significantly improve the responsiveness of conversational systems while likewise reducing the number of queries managed on the search back-end

Religious Pilgrimage: Experiencing Places, Objects and Events

This article explores the concept of the Eventization of faith (Pfadenhauer, 2010) through application of three case studies, to identify learning that might be applied to a traditional pilgrimage destination, such as Jerusalem. This Holy City is held sacred by the three Abrahamic religions, and faith-based tourism is central both to the Holy Land and to the city of Jerusalem (Leppakari & Griffin, 2017). This paper builds on research that identifies processes and models that provide insight into the developing concept of the eventization of faith. The work examines outcomes from three different perspectives: - The impact of traditional church-led pilgrimages to places in the Holy Land, on participants and their local church communities. - The successful eventization of the Lindisfarne Gospels as part of their release to Durham University in 2013, and the impact on local historical, cultural and religious identity and heritage (Dowson, 2019). - The shared pilgrimage experience of thousands of Christian women participating in the annual Cherish Conference in Leeds, Yorkshire, held in a secular event venue (Dowson, 2016). In analysing these three case study examples, this paper aims to identify factors that might enhance our understanding of the concept of eventization of faith. Utilising face to face interviews and online survey results, the research focuses on the aspects of community, identity and authenticity. Events enable shared experiences in a faith context (Lee et al., 2015), and so this research develops a model that captures and expresses approaches that might encourage pilgrimages to traditional destinations, through the medium of events, adding insight into the development of the academic concept of Eventization of Faith

Anti-PD1 Consolidation in Patients with Hodgkin Lymphoma at High Risk of Relapse after Autologous Stem Cell Transplantation: A Multicenter Real-Life Study

(1) Background: Consolidation therapy is an emerging strategy for patients with relapsed/refractory (RR) Hodgkin Lymphoma (HL) at high risk of failing salvage autologous stem cell transplantation (ASCT). (2) Objectives: To assess the safety and effectiveness of PD1-blockade consolidation for these high-risk patients. (3) Design: Multi-center retrospective analysis. (4) Methods: We identified 26 patients given anti-PD1 consolidation, from June 2016 to May 2020. (5) Results: Patients displayed the following risk factors: refractory disease (69%), relapse 3, occurred in 12 patients (46.15%) and mainly included skin rashes (41.7%), transaminitis (33.3%), and thyroid hypofunction (25%). Patients completed a median of 13 courses (range 6–30). At a median follow-up of 25.8 months post-ASCT, the median progression-free (PFS) was 42.6 months, with a 2-year PFS and overall survival rates of 79% and 87%, respectively. (6) Conclusions: Post-ASCT consolidation with anti-PD1 is feasible and effective. Further studies are warranted to define the optimal treatment length and patients’ subsets more likely to benefit from this approach

Evidence-based tailored nutrition educational intervention improves adherence to dietary guidelines, anthropometric measures and serum metabolic biomarkers in early-stage breast cancer patients: A prospective interventional study

Purpose: The impact of the adherence to dietary guidelines of early-stage breast cancer (EBC) patients on body composition changes during treatment is not entirely defined. This study aimed to evaluate the role of an evidence-based nutrition educational intervention, according to adherence to dietary guidelines, in EBC patients. Methods: This prospective study included EBC patients, candidates for neoadjuvant/adjuvant therapy. Patients received an evidence-based tailored nutrition educational intervention. The adherence to dietary guidelines, anthropometric and dietary assessments, and blood glucose and lipid profile tests were evaluated at baseline and after a 12-months nutritional intervention. Results: Two hundred and forty-three patients were enrolled. At baseline, 38.3% and 23.9% of patients were overweight and obese, weight gain ≥5% (compared to 6-months before enrollment) and central obesity were observed in 47.3% and 52.7% of patients, respectively. Adherence to dietary guidelines was low (median Med-Diet score: 6 [IQR 4-8]). After the nutritional intervention (median follow-up: 22 months [range 12-45]), adherence to dietary guidelines significantly increased (median Med-Diet score: 12 [IQR 8-13]), p < 0.0001). High adherence to dietary guidelines (defines as Med-Diet score ≥10) significantly correlated with: 1) overall weight loss ≥5% (21.8% vs. 2.5%, p = 0.003); 2) median BMI drop (from 25.6 kg/m2 to 24.4 kg/m2, p = 0.003); 3) lower prevalence of central obesity (38.2% vs. 7.2%, p = 0.01); 4) improvement in blood glucose levels and lipid profile. Conclusion: This study suggests that an evidence-based tailored nutrition educational intervention during treatment for EBC significantly increases overall adherence to dietary guidelines, and it improves both anthropometric measures and serum metabolic biomarkers in patients with high adherence

Nutrition and IBD: Malnutrition and/or Sarcopenia? A Practical Guide

Malnutrition is a major complication of inflammatory bowel disease (IBD). This mini review is focusing on main determinants of malnutrition in IBD, the most important components of malnutrition, including lean mass loss and sarcopenia, as an emerging problem. Each one of these components needs to be well considered in a correct nutritional evaluation of an IBD patient in order to build a correct multidisciplinary approach. The review is then focusing on possible instrumental and clinical armamentarium for the nutritional evaluation

Low transmission of SARS-CoV-2 derived from children in family clusters: An observational study of family households in the Barcelona Metropolitan Area, Spain

Background: Family clusters offer a good opportunity to study viral transmission in a stable setting. We aimed to analyze the specific role of children in transmission of SARS-CoV-2 within households. Methods: A prospective, longitudinal, observational study, including children with documented acute SARS-CoV-2 infection attending 22 summer-schools in Barcelona, Spain, was performed. Moreover, other patients and families coming from other school-like environments that voluntarily accessed the study were also studied. A longitudinal follow-up (5 weeks) of the family clusters was conducted to determine whether the children considered to be primary cases were able to transmit the virus to other family members. The household reproduction number (Re*) and the secondary attack rate (SAR) were calculated. Results: 1905 children from the summer schools were screened for SARS-CoV-2 infection and 22 (1.15%) tested positive. Moreover, 32 additional children accessed the study voluntarily. Of these, 37 children and their 26 households were studied completely. In half of the cases (13/26), the primary case was considered to be a child and secondary transmission to other members of the household was observed in 3/13, with a SAR of 14.2% and a Re* of 0.46. Conversely, the SAR of adult primary cases was 72.2% including the kids that gave rise to the contact tracing study, and 61.5% without them, and the estimated Re* was 2.6. In 4/13 of the paediatric primary cases (30.0%), nasopharyngeal PCR was persistently positive > 1 week after diagnosis, and 3/4 of these children infected another family member (p<0.01). Conclusions: Children may not be the main drivers of the infection in household transmission clusters in the study population. A prolonged positive PCR could be associated with higher transmissibility.Peer ReviewedObjectius de Desenvolupament Sostenible::3 - Salut i BenestarPostprint (published version

Terrorism, Tourism and Religious Travellers

Curiously, while tourism is cited as the world’s largest industry (UNWTO, 2016), it is simultaneously a fragile industry that is highly vulnerable to the impact of the ongoing threat of terrorism. Internationally, terrorism influences the tourist mind-set in a number of ways, in particular it creates fear for travellers and causes economic and social impacts to change the behaviour of people and dissuade them from visiting certain places in the world. Thus, the impact of terrorism has caused tremendous damage to the travel industry. A number of countries which previously depended quite heavily on the tourism industry are suffering in terms of economic development. This paper discusses critical issues related to terrorism, that are faced by travellers to religious and sacred sites. The paper will illustrate the impact of recent terrorism phenomena upon travellers in two ways: first, the potential personal hazards to travellers caused by terrorist incidents; second, the impacts caused by stringent anti-terrorism laws and security measures, to travellers while they are in transit

Clinical Impact of Nutritional Status and Sarcopenia in Pediatric Patients with Bone and Soft Tissue Sarcomas: A Pilot Retrospective Study (SarcoPed)

Background: We evaluated nutritional and sarcopenia status and their clinical impact in pediatric patients affected by bone and soft tissue sarcomas. Methods: Body mass index (BMI), prognostic nutritional index (PNI), and total psoas muscle area (tPMA) at diagnosis and after 12 months were analyzed. tPMA was measured from single cross-sectional computed tomography (CT) images at L4-L5. Age-specific and sex-specific tPMA Z-scores were retrieved from an online calculator. Results: A total of 21 patients were identified between February 2013 and December 2018. Twelve patients (57.1%) experienced sarcopenia at diagnosis, although not statistically associated with overall survival (OS) (p = 0.09). BMI Z-score, PNI, and tPMA Z-score significantly decreased between diagnosis and after 12 months of treatment (p &lt; 0.05). Univariate analysis showed significant associations between poor OS and the presence of metastasis (p = 0.008), the absence of surgery (p = 0.005), PNI decrease (p = 0.027), and the reduction in tPMA &gt; 25% (p = 0.042) over the 12 months. Conclusions: Sarcopenia affects more than half of the patients at diagnosis. Decreased PNI during 12 months of treatment has significant predictive value for OS. The role of tPMA derived from CT scan among pediatric patients with sarcoma should be investigated in further prospective and larger studies

Roadmap on thermoelectricity

The increasing energy demand and the ever more pressing need for clean technologies of energy conversion pose one of the most urgent and complicated issues of our age. Thermoelectricity, namely the direct conversion of waste heat into electricity, is a promising technique based on a long-standing physical phenomenon, which still has not fully developed its potential, mainly due to the low efficiency of the process. In order to improve the thermoelectric performance, a huge effort is being made by physicists, materials scientists and engineers, with the primary aims of better understanding the fundamental issues ruling the improvement of the thermoelectric figure of merit, and finally building the most efficient thermoelectric devices. In this Roadmap an overview is given about the most recent experimental and computational results obtained within the Italian research community on the optimization of composition and morphology of some thermoelectric materials, as well as on the design of thermoelectric and hybrid thermoelectric/photovoltaic devices
