The SARS-CoV-2 pandemic has affected also the school environment. Prolonged closures and the weakness of available data prevent a definitive answer to the question of school transmission. We report ...our experience of responding to COVID-19 cases in the school setting, presenting a case study of the management of an outbreak in a large school.
The LHA/ASL Roma 1 has organized the School Units with a structure firmly rooted in the territory. At the local level, the District Unit mainly manages the relationship with schools, while the Hygiene and Public Health Service of the Prevention Department holds a coordinating and facilitating role. The HPHS carries out contact tracing activities facilitated by the schools, through the figure of the COVID-19 Contact Person, who is specifically trained to manage the preliminary stages of the reports.
Following several reports of COVID-19 suspect cases from two schools and, after a complex phase of contact tracing, it was possible to identify the major transmission chains. Furthermore, we performed a population-based screening on the entire school. Beyond the known transmission chains, for which quarantine was already in place, only five additional cases emerged, all asymptomatic, out of 1,231 swabs tested with RT-PCR.
Our experience confirms that an active interaction between the school and the School Unit made it possible to quickly control a potentially dangerous outbreak. The large-scale screening test demonstrated the substantial absence of collateral transmission chains. Effective contact tracing allowed to set forth a successful response. Our model of intervention can be used to support public health protocols regarding school outbreaks.
Abstract Digital platforms have the ability to connect people, organizations and resources with the aim of facilitating the core interactions between businesses and consumers as well as assuring a ...greater efficiency for the business management. New business concepts, such as innovative start-ups, are therefore created based on innovation, scalability and the relationships within the community around them. The purpose of this work is to deeply understand the evolution of business models brought by innovative and dynamic companies operating through online platforms. In order to achieve the objectives set, an exploratory multiple-case study was designed based on in-depth structured interviews. The aim was to conduct a mixed analysis, in order to rely both on qualitative and quantitative data. The structured interview protocol was therefore designed to collect and then analyse data concerning the company profile and managers’ perspectives on the phenomenon of interest. The interview protocol was submitted in advance and then face-to-face interviews were carried out with the following professional figures: Chief Executive Officer (CEO), General Manager, Chief Technology Officer (CTO), Marketing Manager and Developers. Collected data were analysed and processed through the Canvas Business Model in order to clearly outline similarities and differences among the sample. Results can be considered under two viewpoints. On the one hand, this work provides a detailed overview of the companies interviewed, according to the dimensions of: reference market dynamics, type and number of customers, scalability. On the other one, they allow to identify some success patterns regarding key activities, key resources, channel mix strategy, costs management, value proposition, customer segmentation, key partners and the way to obtain revenues. Results from the multiple-case study with 15 Italian start-ups provide interesting insights by comparing the innovative business models developed and highlighting key differences and similarities. Overall, the start-ups analyzed, operating in several sectors, showed great growth prospects and the possibility to create value for their customers through innovative products and services offered through digital platforms.
Psycholinguistic research on metaphor has focused on verbal material. Yet, metaphors frequently occur in a multimodal format, blending words and pictures to convey meaning. Here we compared verbal ...and multimodal metaphors by using item pairs where stimulus one was always a word (e.g., language in the metaphorical conditions and river in the literal conditions) and stimulus two was either a word (bridge) or a picture (the image of a bridge). The two types of metaphors elicited a similar N400 effect compared to literal pairs; at later latencies, visual metaphors were associated with a more pronounced negativity compared to literal pictures, whereas no effect was observed in the verbal domain. These findings indicate that both visual and verbal metaphors recruit conceptual operations reflected in the N400, but for visual metaphors, elaboration lasts longer. This difference in time course was driven by the low number of alternative interpretations and their closedness, pointing to the costs, rather than the facilitation, of integrating visual signs at an abstract level of representation.
Healthcare workers (HCWs) are an important group of professionals exposed to biological risk during their work activities. So, the aim of this study is to perform a survey on the knowledge, attitude ...and behaviour of Italian HCWs towards the vaccinations recommended by the Ministry of Health. A cross-sectional study was carried out during the period September 2014-August 2015 in the Lazio region. The study was conducted by recruiting HCWs and biomedical students. The sample was comprised of 571 responders, of whom 12.4% were physicians, 18.9% were nurses, 34.3% were other HCW, and 34.3% were biomedical students (medical and nurses students). Hepatitis B virus (HBV) is perceived as a risk for personal health by 457 (80%) participants; TB is also worrying (434; 76%). Moreover, HBV (70.9%) and tuberculosis (TB) (79.2%) are perceived as a risk for health, while influenza is not considered so by most participants (46.2%). There is an underestimation of the role of influenza, perceived as a risk for 137 respondents (24%). The vaccination rate among these HCWs is highest for Hepatitis B virus (HBV) (82%), and lowest for influenza (28.5%) and varicella (40.3%). The vast majority of responders are in favour of HBV (77.8%) and TB (64.8%) vaccines. For other vaccinations there is less interest (between 33% and 40% for measles, mumps, rubella, pertussis and influenza). This study shows that knowledge of recommended occupational vaccinations is insufficient in HCWs, with few exceptions represented by HBV and TB. There is a need for novel approaches in this field, with the aim of enhancing vaccine coverage among HCW.
Spectrum crowdsensing systems do not provide labeled data near real-time yet. We propose a framework that addresses this challenge and relies solely on Power Spectrum Density (PSD) data collected by ...low-cost receivers. A major hurdle is to design a system that is computationally efficient for near real-time operation, yet using only the limited 2 MHz bandwidth of low-cost spectrum sensors. First, we present a method for unsupervised transmission detection that works with PSD data already collected by the backend of the crowdsensing platform, and that provides stable detection of transmission boundaries. Second, we introduce a data-driven deep learning solution to classify the wireless technology used by the transmitter, using transmission features in a compressed space extracted from single PSD measurements over at most 2 MHz band. We build an experimental platform, and evaluate our framework with real-world data collected from 47 different sensors deployed across Europe. We show that our framework yields an average classification accuracy close to 94.25% over the testing dataset, with a maximum latency of 3.4 seconds when integrated in the backend of a major crowdsensing network. Code and data have been released for reproducibility and further studies.
Academics often have to face with burnout syndrome at work. This cross-sectional study evaluates the reliability of the Italian version of the Copenhagen Burnout Inventory (CBI) in a sample of ...Academics of Sapienza University of Faculty of Medicine and Pharmacy, through an online questionnaire composed of the CBI, SF12 Health Survey, and Positivity Scale. Univariate, bivariate, multivariate analyses, and Cronbach α coefficients of CBI were performed. Ninety-five participants completed the questionnaire (response rate 85%). Cronbach's α of the three domains were high (0.892, 0.868, and 0.836). Women, younger and part time professors reported higher score in personal (
= 0.025; 0.060) and work burnout. In multivariate analysis decreasing age (β = -0.263;
= 0.001); being a professor in environmental technicians (β = -0.120;
= 0.098); and low mental (β = -0.263;
= 0.020), physical (β = -0.319;
≤ 0.001) and positivity scores (β = -0.237;
= 0.031) predict significantly higher personal burnout. Low physical (β = -0.346;
< 0.001) and mental (β = - 0.249;
= 0.013) positivity (β = -0.345;
= 0.001) scores; fewer years of work (β = -0.269;
≤ 0.001); and being a medical or nursing professor (β = 0.169;
= 0.016) predicts high work burnout. Low MCS predicts a high level of student burnout. Results suggest that the Italian version of the CBI is a reliable instrument. Further research should focus on the prevalence of burnout in academics.
The paper is part of a broader research project studying consumer’s attitude towards “Made in Italy” products through empirical investigation. The research questions addressed are: 1) Does ...recognition in terms of the qualitative characterization of “Made in Italy” products exist? And if so, 2) are people willing to pay, in quantitative terms, a premium price for such products? From a theoretical standpoint, the research seeks to fill a gap in the literature, since studies combining the “made in” characteristic with measured “willingness to pay” are neither conventional nor numerous. The specific purpose of this contribution is to analyze the relationship between the purchase of “Made in Italy” products, recognition of the quality and willingness to pay a premium price on the part of Italian consumers, reporting the results of an empirical research. The survey involved a total of 315 Italian consumers while three commodity sectors were analysed: food, fashion and mechanical automation. The results confirm that there is a propensity to purchase “Made in Italy” products which does not seem to be a matter of irrational consumer behaviour. “Made in Italy” is confirmed as a conceptual category consolidated in the minds of consumers, since there is clear recognition of these products in terms of qualitative characterization. These and other results of the research (which need to be confirmed and extended with further empirical investigations) should prove relevant both to the literature and as indications for public policies and the strategies of companies operating in the sectors examined. For the literature this research can be useful because there is no complete overview of quantitative data on the premium price. It can also serve for public policies because quantification of the premium price can influence the choices and strategies of companies. This study shows a significant willingness to pay a premium price for the three sectors analyzed, although the premium price is not homogeneous: while the measures range mostly between 10 and 30%, higher values appear for products in the food sector.
The State Route 520/Evergreen Point Floating in Seattle, Washington, is vulnerable to windstorms and earthquakes and needs to be replaced. The Washington State Department of Transportation (WSDOT) ...recognizes the need to have a plan in place to manage traffic and communications if the SR 520 floating bridge were lost in such an event. The plan was developed in collaboration with regional jurisdictions, transit agencies, emergency responders, and businesses, as a toolkit of strategies that could be implemented quickly and effectively to benefit the region. WSDOT also invited engineers from Minnesota DOT to contribute to the plan by sharing their experience from I-35W bridge collapse and recovery. The main components of the plan are the Transportation Management Plan and the Communications Plan. A regional tabletop exercise focusing on a SR 520 catastrophic failure scenario helped to inform the development of the plan. The SR 520 Catastrophic Failure Plan provides a basis for WSDOT to prepare for a catastrophic bridge failure and for local jurisdictions to develop their own emergency response plans.
