Emotional Reactions to the Perception of Risk in the Pompeii Archaeological Park

The assessment of perceived risk by people is extremely important for safety and security management. Each person is based on the opinion of others to make a choice and the Internet represents the place where these opinions are mostly researched, found and reviewed. Social networks have a decisive impact: 92% of consumers say they have more trust in social media reviews than in any other form of advertising. For this reason, Opinion Mining and Sentiment Analysis have found interesting applications in the most diverse context, among which the most innovative is certainly represented by public safety and security. Security managers can use the perceptions expressed by people to discover the unexpected and potential weaknesses of a controlled environment or otherwise the risk and security perception of people that sometimes can be very different from real level of risk and security of a given site. Since the perceptions are the result of mostly unconscious elaborations, it is necessary to go deeper and to search for the emotions, triggered by the sensorial stimuli, that determine them. The objective of this paper is to study the perception of risk within the Pompeii Archaeological Park, giving emphasis to the emotional components, using the semantic analysis of the textual contents present in Twitter.Peer reviewe

The role of cognitive frames towards circular economy practices in SMEs

Frame of the research: The paper explores how organizations are able to manage potential competing logics in the HORECA and Hospitality sectors. In such sectors, mainly characterized by SMEs and where the effect of brand and corporate reputation is not comparable with some manufacturing sectors operating in the B2B market, finding an equilibrium between the economic and environmental need is crucial in order to truly embrace environmental sustainability. Purpose of the paper: The development of an integrative cognitive framework in management where environmental and economic views are strictly enwound, is crucial for supporting the transition towards a more circular economy. The paper explores the drivers for developing such integrative view for the managers of SMEs operating in the hospitality sectors. Methodology: The research is grounded on original data collected by a survey of 252 Italian SMEs operating in the hospitality sector. Adopting a structural equation model, we tested the drivers that can contribute to create respectively an environmental and economic logic in managers, whether the co-presence of these logics is able to generate an integrative view and, as a consequence, the influence of such view on the adoption of pro-environmental practices. Findings: The results confirm the environmental concern being a driver of environmental logic, the importance of the environmental logic and the economic one as determinants of the integrative view and the importance of such view in adopting pro-environmental practices. Research limits: The study is focused on a specific geographical context. The number of drivers of environmental internalization could be expanded. Practical implications: The study contributes to the steam of research on sustainability among SMEs by stressing how intangible factors are crucial for reaching environmental embeddedness. Originality of the paper: Understanding how organizations are able to manage potential competing logics in an integrative cognitive framework is still unexplored, mainly in the Hospitality sectors. In such sectors finding an equilibrium between the economic and the environmental need is crucial for really embracing environmental sustainability

Monitoring Appropriate Monoclonal Antibodies Prescribing via Administrative Data: An Application to Psoriasis

: The Italian Medicines Agency (AIFA) and the Italian Regional Health Systems have implemented measures together with data collection and analysis to improve medicines' appropriate prescription. Administrative databases represent rich Real-World Evidence (RWE) sources that may be leveraged for research purposes. Thus, such heritage may allow for appropriate prescription studies to be carried out on complex pharmaceutical molecules, as the appropriateness of prescriptions is essential both for patients' treatment and to ensure healthcare systems' sustainability. This study analyzed the appropriate monoclonal antibodies (mAbs) prescribed in psoriasis treatment across Tuscany, Italy. Data were extracted from several large administrative databases collected by the Tuscan Regional Healthcare System through record linkages. The analysis showed that over 30% of the 2020 cohort of psoriatic patients could be regarded as potentially inappropriate treated, signaling that mAbs are often prescribed as first-line treatment contrary to guidelines. Variation was observed in the appropriate prescription of mAbs, across different types of mAbs and areas. The study revealed potential inappropriate prescription, and its geographic variation should raise awareness among managers about the appropriate use of resources. Despite limitations, this could represent a pilot for future studies to evaluate the appropriate prescription of mAbs in other clinic conditions and across time

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (https://creativecommons.org/licenses/by/4.0/).This paper proposes a methodology for sentiment analysis with emphasis on the emotional aspects of people visiting the Herculaneum Archaeological Park. The methodology provides a valuable means of continuous feedback on perceived risk of the site. A semantic analysis on Twitter text messages provides input to the risk management team with which they can respond immediately mitigating any apparent risk and reducing the perceived risk. In addition, we analyse the sentiments of people of such a cultural heritage before and during the Covid pandemic. Whilst suffering from the disease, equally people suffered due to loneliness from isolation as declared by the World Health Organisation. Despite such conditions, people’s sentiments demonstrated a positive effect from the online discussions on the Herculaneum site. This is what we have demonstrated in this work through sentiment analysis.Peer reviewe

The impact of multisensory integration and perceptual load in virtual reality settings on performance, workload and presence

Real-world experience is typically multimodal. Evidence indicates that the facilitation in the detection of multisensory stimuli is modulated by the perceptual load, the amount of information involved in the processing of the stimuli. Here, we used a realistic virtual reality environment while concomitantly acquiring Electroencephalography (EEG) and Galvanic Skin Response (GSR) to investigate how multisensory signals impact target detection in two conditions, high and low perceptual load. Different multimodal stimuli (auditory and vibrotactile) were presented, alone or in combination with the visual target. Results showed that only in the high load condition, multisensory stimuli significantly improve performance, compared to visual stimulation alone. Multisensory stimulation also decreases the EEG-based workload. Instead, the perceived workload, according to the "NASA Task Load Index" questionnaire, was reduced only by the trimodal condition (i.e., visual, auditory, tactile). This trimodal stimulation was more effective in enhancing the sense of presence, that is the feeling of being in the virtual environment, compared to the bimodal or unimodal stimulation. Also, we show that in the high load task, the GSR components are higher compared to the low load condition. Finally, the multimodal stimulation (Visual-Audio-Tactile-VAT and Visual-Audio-VA) induced a significant decrease in latency, and a significant increase in the amplitude of the P300 potentials with respect to the unimodal (visual) and visual and tactile bimodal stimulation, suggesting a faster and more effective processing and detection of stimuli if auditory stimulation is included. Overall, these findings provide insights into the relationship between multisensory integration and human behavior and cognition

Dissolved Inorganic Nutrients in the Western Mediterranean Sea (2004-2017)

Abstract. Long-term time-series are a fundamental prerequisite to understand and detect climate shifts and trends. Understanding the complex interplay of changing ocean variables and the biological implication for marine ecosystems requires extensive data collection for monitoring and hypothesis testing and validation of modelling products. In marginal seas, such as Mediterranean Sea, there are still monitoring gaps, both in time and in space. To contribute filling these gaps, an extensive dataset of dissolved inorganic nutrients profiles (nitrate, NO3; phosphate, PO4 ; and silicate, SiO2) have been collected between 2004 and 2017 in the Western Mediterranean Sea and subjected to quality control techniques to provide to the scientific community a publicly available, long-term, quality controlled, internally consistent biogeochemical data product. The database includes 27 870 stations of dissolved inorganic nutrients sampled during 24 cruises, including temperature and salinity. Details of the quality control (primary and secondary quality control) applied are reported. The data are available in PANGAEA (https://doi.pangaea.de/10.1594/PANGAEA.904172, Belgacem et al. 2019) Keywords: Mediterranean Sea, Dissolved Inorganic Nutrient, biogeochemistr

Microbial community of the deep-sea brine Lake <em>Kryos </em>seawater-brine interface is active below the chaotropicity limit of life as revealed by recovery of mRNA

Within the complex of deep, hypersaline anoxic lakes (DHALs) of the Mediterranean Ridge we identified a new, unexplored DHAL and named it "Lake Kryos" after a nearby depression. This lake is filled with MgCl2-rich, athalassohaline brine (salinity >470 practical salinity units), presumably formed by the dissolution of Messinian bischofite. Compared to the DHAL Discovery, it contains elevated concentrations of kosmotropic sodium and sulfate ions, which are capable of reducing the net chaotropicily of MgCl2-rich solutions. The brine of Lake Kryos may therefore be biologically permissive at MgCl2 concentrations previously considered incompatible with life. We characterized the microbiology of the seawater-Kryos brine interface and managed to recover mRNA from the 2.27-3.03 M MgCl2 layer (equivalent to 0.747-0.631 water-activity) thereby expanding the established chaotropicity window-for-life. The primary bacterial taxa present there were KB1 candidate division and DHAL-specific group of organisms, distantly related to Desulfohalobium. Two euryarchaeal candidate divisions MSBL1 and HC1, detected in minority in the overlaying layers, accounted for more than 85% of the rRNA-containing archaeal clones analyzed in 2.27-3.03 M MgCl2 layer. These findings shed light on the plausibility of life in highly chaotropic environments, geochemical windows for microbial extremophiles, and have implications for habitability elsewhere in the Solar System

SOS - Piattaforme e Impatti Offshore Report tecnico. I Campagna oceanografica 13-19 maggio 2018

Nell’ambito della convenzione stipulata tra il Ministero dell’Ambiente e della Tutela del Territorio e del Mare (MATTM) e il Dipartimento Scienze del Sistema Terra e Tecnologie per l’Ambiente del CNR (DTA), “SOS-Piattaforme & Impatti Off-Shore” è stata prevista un’indagine ambientale nell’area di interesse di 10 piattaforme off-shore ENI presenti nella zona costiera compresa tra Ravenna e Pescara. In particolare, le attività previste fanno riferimento alla sezione Macro-Attività D della convenzione. Obiettivo principale delle attività di indagine è lo studio della modalità di dispersione in mare delle acque di produzione e una caratterizzazione chimico-fisica ed ecotossicologica delle stesse e delle matrici ambientali (acqua, sedimenti, biota) che ricevono lo scarico. L’attività di ricerca prevede un approccio di analisi ‘integrato’ di tipo chimico, e fisico per lo studio degli effetti della dispersione in mare delle acque di produzione ed ecotossicologico per la valutazione di eventuali danni a organismi selezionati dopo la loro esposizione all’acqua di produzione e all’acqua di mare prelevata a diverse distanze dal punto di scarico. Inoltre, l’azione di ricerca è volta alla definizione di un approccio metodologico innovativo per le future attività di monitoraggio da effettuare attorno alle piattaforme off-shore per la verifica di processi e meccanismi di impatto sull’ambiente e l’ecosistema principalmente da parte dello scarico di acque di produzione. Questa relazione descrive le attività di campionamento e acquisizione dati effettuate durante la I Campagna Oceanografica nell’ambito della convenzione “SOS-Piattaforme & Impatti Off-Shore”. La campagna di campionamento si è svolta nel periodo 13-19 maggio 2018 a bordo del mezzo navale ROCCO UNO della Marine Consulting International e dei mezzi navali ENI KING DAVID e MARE GRIGIO
