Personal and Environmental Risk Factors at Birth and Hospital Admission: Direct and Vitamin D-Mediated Effects on Bronchiolitis Hospitalization
2021
Abstract: Seasonal variations in UV-B radiation may influence vitamin D status, and this, in turn, may influence the risk of bronchiolitis hospitalization. The aim of this study was using a causal inference approach to investigate, simultaneously, the interrelationships between personal and environmental risk factors at birth/hospital admission (RFBH), serum vitamin D levels and bronchiolitis hospitalization. A total of 63 children (<2 years old) hospitalized for bronchiolitis (34 RSV-positive) and 63 controls were consecutively enrolled (2014-2016). Vitamin D levels and some RFBH (birth season, birth weight, gestational age, gender, age, weight, hospitalization season) were recorded. The d…
Innovative In Situ and Ex Situ Conservation Strategies of the Madonie Fir Abies nebrodensis
2022
Abies nebrodensis (Lojac.) Mattei is an endemic species of the north-west of Sicily located in an 84 ha area in the Madonie Regional park. The current population is limited to 30 relic adult trees and a fluctuating number of juveniles of natural regeneration. The species is defined as “Critically Endangered” in the Italian list of threatened plants and is classified as CR-D in the 2000 IUCN Red List of Threatened Species. This article reports the key action undertaken by the LIFE4FIR project aimed at preserving A. nebrodensis, and the results obtained so far in three years of activity. OpenArrays SNPs genotyping revealed a high rate of inbreeding in the natural population and that the adult…

La biodiversità dei boschi siciliani. Parte I: l’avifauna
2014
È stata censita la diversità delle specie ornitiche presente in alcune tipologie forestali della Regione Siciliana e la relazione tra le ornitocenosi, le scelte gestionali ed i diversi fattori abiotici e biotici. L’analisi della species richness (= numero delle specie) dimostra che essa è correlata con il bioclima, il diametro massimo degli individui arborei, il valore trofico di tutti gli strati di vegetazione ed il valore trofico dello strato arboreo. I boschi meso-supramediterranei sono più ricchi di specie rispetto ai boschi termomesomediterranei. L’importanza del diametro massimo degli individui arborei, che esprime indirettamente anche il tipo di gestione di un bosco, viene spiegata d…
Le processus de choix alimentaire et ses déterminants : vers une prise en compte des caractéristiques psychologiques du consommateur
2006
This thesis aims to explore new research opportunities in the food field, proposing to explicitly include psychological factors as potential determinants of food choice process. It notes the consequences of the central role of pleasure in the mechanisms of ingestion, and the specific role of taste: the highly emotional nature of food consumption leads then to retain experiential approach and more specifically sensory marketing as a framework. The issue of research aims to investigate how sensory stimuli and the information associated with the product combine to influence, in a differentiated manner depending on the individual, consumption behavior.Methodologically, the research combines con…
Effects of Using Standing Versus Sitting Workstations on the Well-Being at Work of Software Professionals
2016
Although people admittedly are one of the most valuable assets of many software companies, relatively little academic research has been done from the well-being at work aspect of software professionals. This intervention study aims to address this gap in prior research by examining the potential effects of using standing instead of sitting workstations on the well-being at work of software professionals in terms of physical activity, mental alertness, and stress. The two measurements before and after the intervention were conducted in June and September 2015 for 29 employees of a local site of a large Finnish software company by using questionnaires and the Firstbeat Lifestyle Assessment se…
Afforestation and reforestation: the Sicilian case study
2014
In some regions of the world such as the Northern Hemisphere, the abandonment of agricultural land is one of the most widespread forms of land use change. In general, abandonment is followed by colonization by herbaceous and woody plants. Since the 1950s, wide areas of Southern Italy have been afforested for soil conservation improvement. In order to quantify the effects of agricultural abandonment and artificial afforestation on soil organic carbon (SOC), a dataset of 48 Sicilian sites has been analyzed. Because of their high environmental variability, these sites can be considered as representative of Southern Italy and in general of the Mediterranean basin. Soil samples were taken throug…
Muscle activity patterns and spinal shrinkage in office workers using a sit–stand workstation versus a sit workstation
2016
Reducing sitting time by means of sit–stand workstations is an emerging trend, but further evidence is needed regarding their health benefits. This cross-sectional study compared work time muscle activity patterns and spinal shrinkage between office workers (aged 24–62, 58.3% female) who used either a sit–stand workstation (Sit–Stand group, n = 10) or a traditional sit workstation (Sit group, n = 14) for at least the past three months. During one typical workday, muscle inactivity and activity from quadriceps and hamstrings were monitored using electromyography shorts, and spinal shrinkage was measured using stadiometry before and after the workday. Compared with the Sit group, the Sit–Stan…
An equation to calculate the availability for the k-out-of-n system
2016
Reliability and availability (R&A) analyses are primary phases in management of complex systems and play a fundamental role in products and services quality. Management of maintenance activities has to be based on optimisation to simultaneously improve the operative conditions of the system. Maintenance optimization can be effeectively pursued by the RCM (Reliability-centered maintenance) approach. The authors demonstrate the global improvement of R&A by applying the RCM to the results derived by the FMECA (Failure Modes Effects and Criticality Analysis). Many efforts have been made to improve traditional methodologies of analysis, mainly tending to reduce the imprecision on data related to…
Le stationnement à Besançon
1999
Depuis les années 1950, le recours à l'automobile pour de courts trajets quotidiens ne cesse de croître au détriment des autres moyens de transport, ce qui occasionne divers désagréments :encombrements qui engendrent la disparition des fonctions sociales de la rue, atteintes à l'environnement urbain qui dégradent la qualité de vie, accidents de la route générés par la densité et la rapidité du trafic.
