Diversity in Teams : Perceptions of Team Learning Behaviour in a Military Staff Exercise

2020

The aim of this study is to analyse diversity in team learning behaviour between and among national respondents’ perceptions during a military staff exercise (CJSE). Edmondson’s team learning behaviour model is used as the theoretical basis of the study. The results showed statistically significant differences both between and among national respondents’ perceptions. The research results indicate that team leader coaching, team psychological safety, the importance of obtaining expert knowledge as well as pre-exercise training are perceived to be crucial for team learning behaviour. The study has theoretical and practical implications for a more nuanced understanding of the diversity of team…

Microbial strategies to improve the final quality of traditional Sicilian cheeses

Preliminary thermal-hydraulic analysis of the EU-DEMO Helium-Cooled Pebble Bed fusion reactor by using the RELAP5-3D system code

2021

Abstract In the frame of the activities promoted and encouraged by the EUROfusion Consortium aimed at developing the EU-DEMO fusion reactor, great emphasis has been placed at a very early stage of the design to incorporate the provisions needed to improve the overall plant safety and reliability performances as well as to analyse possible mitigation actions. In this framework, the research activity has been focused on the representative and safety relevant cooling loop of the Helium Cooled Pebble Bed (HCPB) Breeding Blanket (BB) Primary Heat Transfer System (PHTS), purposely selected by the safety team, in order to assess its thermal-hydraulic behaviour during normal operational conditions …

'Where Have I Heard It?' Assessing the Recall of Traffic Safety Campaigns in the Dominican Republic

2021

Although traffic crashes are the eighth leading cause of death in the world, and are linked to vehicle and infrastructure-related factors, crash-related fatality rates are much higher in lowincome countries. Particularly, the Dominican Republic is the country with the highest accident rate in the whole American continent. Therefore, in the past few years, public agencies have been developing different measures aimed at reducing traffic fatalities, including road safety campaigns. The aim of the present study was to assess the recalling of such campaigns among the Dominican population, which may serve as an additional indicator to evaluate their effectiveness in this and other countries of t…

Graphical and Analytical Quantitative Comparison in the Domes Assessment: The Case of San Francesco di Paola

2021

(1) Methods for checking the condition of monumental masonry structures can still be considered understudied. Among the different approaches available in the literature, the graphical ones have a special role, due to their simplicity and effectiveness. (2) In this work, a 2D method (Thrust Line Analysis (TLA)), the Modified Thrust Line Method (MTLM), and the 3D Membrane Equilibrium Analysis (MEA) method are compared. All methods have the same starting concept: no tensile strength, no sliding between the stone blocks, infinite compressive strength. (3) The methods are compared in terms of stress distribution (for the same—or similar—thrust line), and in terms of the Geometrical Safety Factor…

Education for Road Safety: What is the State of Affairs in Three Groups of Vulnerable Road Users in Spain?

2021

RSE (Road Safety Education) is well recognized as a reliable predictor of future safety and health outcomes. However, most countries have been slow to develop it, which has contributed to the sensitivity of the situation, as traffic accidents continue to be a major concern for community health. This paper aims to describe and compare key variables related to the RSE among three critical segments of the population, using the data provided by: 477 high school students, 843 university students and 476 older adults. Differential coverage rates were found. Perceived quality, aroused interest and attributed utility for RSE interventions were also compared among groups, finding substantial differe…

Integrated design of breeding blanket and ancillary systems related to the use of helium or water as a coolant and impact on the overall plant design

2021

Currently, for the EU DEMO, two Breeding Blankets (BBs) have been selected as potential candidates for the integration in the reactor. They are the Water Cooled Lithium Lead and the Helium Cooled Pebble Bed BB concepts. The two BB variants together with the associated ancillary systems drive the design of the overall plant. Therefore, a holistic investigation of integration issues derived by the BB and the installation of its ancillary systems has been performed. The issues related to the water activation due to the 16N and 17N isotopes and the impact on the primary heat transfer systems have been investigated providing guidelines and dedicated solution for the integration of safety devices…

Citizens’ perceptions in relation to transport systems and infrastructures: a nationwide study in the dominican republic

2021

One of the challenges currently faced by emerging countries is to get their citizens to decide to use sustainable transport for their regular trips, in order to reduce the current vehicular pollution rates. The objective of this descriptive research is to examine the perceptions of Dominicans regarding the state of the country’s transport systems and road infrastructure. For this purpose, a nationwide survey procedure was performed. This cross-sectional research used the data retrieved from a sample of 1260 citizens aged over 18, proportional in gender, age, habitat, and province of the Dominican Republic. The results showed how Dominicans believe that, compared to other road features, pede…

How to Prevent SARS-CoV-2 Transmission in the Agri-Food Industry during the First Pandemic Wave: Effects on Seroprevalence

2021

During the SARS-CoV-2 pandemic, many workplaces were forced to interrupt their activities or alternatively had to prefer a smart way of working, if this was compatible with their activities, to contain the spread of the virus. Some production activities, on the other hand, continued, such as those belonging to the agri-food sector. The aim of the study was to investigate seroprevalence in the workers of an Italian agri-food company following prevention interventions developed in concert with an occupational physician. An observational cohort study was conducted on a population of 328 (100%) workers of a company in the agri-food sector, located in the Sicilian region, which specialized in th…

Dissesto idrogeologico e urban eco-planning. Una proposta per contrastare la fragilità del territorio urbano di Agrigento

2017

I più recenti fenomeni naturali calamitosi che hanno interessato l’Italia si sono verificati in concomitanza di anomali cambiamenti climatici la cui causa è il riscaldamento globale. Il V rapporto dell’IPCC 2014 afferma che il global warming è determinato dalle attività antropiche. A livello mondiale, l’Italia è realmente minacciato dalla “desertificazione” per circa 1/5 del territorio nazionale, soprattutto al Sud: la Sicilia con una percentuale del 70% risulta, in tal senso, la regione più a rischio (“Convegno sulla siccità”, CNR per Expo 2015). Con l’innalzamento delle temperature si ha una diminuzione delle precipitazioni e un aumento dell’intensità delle stesse con pericolo di dissesto…
