Cross-sectional association between active commuting and perceived commuting stress in Austrian adults: Results from the HOTway study
2020
Abstract Objective Little is known about the acute psychological stress responses caused by commuting. Evidence for the benefits of active commuting (e.g., walking, cycling) is usually based on studies without measurements in free-living environments and without consideration of daily variations in stress. This study investigated the association between commuting mode (active, passive) and perceived commuting stress, assessed on multiple days immediately after commuting. Methods Adults participating in the cross-sectional ‘Healthy On The way’ (HOTway) study between 2016 and 2017 in Graz, Austria, were included. Participants completed an online survey and responded to statements about percei…

A new child-centered approach to the organization of extra-curricular activities in Finnish schools
2017
Extracurricular activities are currently included in Finnish school legislation, but their organization is fragmented. History: Club activities at school led by teachers have been arranged since 1947 on extra pay, but their amount and content have depended on available funding and often on teachers’ willingness to lead club activities. Schools have also had a possibility to use cultural or sport operators. However, system has preferred teacher-led club activities. A dramatic change occurred in the early 1990s when economic recession reduced extra funding for schools and day care. Consequently, club activities after school hours were reduced to less than half, and afternoon care services wit…
Adaptation to a seasonally varying environment: a strong latitudinal cline in reproductive diapause combined with high gene flow in Drosophila montan…
2011
Adaptation to seasonal changes in the northern hemisphere includes an ability to predict the forthcoming cold season from gradual changes in environmental cues early enough to prepare for the harsh winter conditions. The magnitude and speed of changes in these cues vary between the latitudes, which induces strong selection pressures for local adaptation. We studied adaptation to seasonal changes in Drosophila montana, a northern maltfly, by defining the photoperiodic conditions leading to adult reproductive diapause along a latitudinal cline in Finland and by measuring genetic differentiation and the amount of gene flow between the sampling sites with microsatellites. Our data revealed a cl…
Geoarchaeological evidence of marshland destruction in the area of Rungholt, present-day Wadden Sea around Hallig Südfall (North Frisia, Germany), by…
2018
Abstract Geophysical and geoarchaeological investigations were carried out in the Wadden Sea of North Frisia (Schleswig-Holstein, Germany) to elucidate major environmental changes that considerably altered the coastal landscape since medieval times. Between the 12 th and 14 th cent. AD, the present-day tidal flats around the marsh island Hallig Sudfall belonged to the historical Edomsharde district and its main settlement Rungholt . For North Frisia, it is well known that during medieval and early modern times, extreme storm surges caused major land losses associated with a massive landward shift of the coastline. Today, cultural traces like remains of dikes, drainage ditches, terps or even…
Considerations about an indicator aimed at describing the energy efficiency of buildings with innovative envelope components at different climatic co…
2020
Green roofs are building components that have become increasingly common in urban contexts because other than the general improvement of the aesthetics of the buildings equipped with them, they have demonstrated to positively improve the building energy performance. Consequently, it would be useful for technicians to have easy and reliable indicators to achieve a synthetic quantitative judgement about the effectiveness of green roofs by an energy perspective compared to others building envelope technologies, for different climates. In sight of the definition of such an indicator, or at least of its properties, some considerations aimed at this purpose, especially concerning the use of new c…
Prolonging in utero-like oxygenation after birth diminishes oxidative stress in the lung and brain of mice pups☆
2013
Background Fetal-to-neonatal transition is associated with oxidative stress. In preterm infants, immaturity of the antioxidant system favours supplemental oxygen-derived morbidity and mortality. Objectives To assess if prolonging in utero-like oxygenation during the fetal-to-neonatal transition limits oxidative stress in the lung and brain, improving postnatal adaptation of mice pups. Material and methods Inspiratory oxygen fraction (FiO2) in pregnant mice was reduced from 21% (room air) to 14% (hypoxia) 8–12 h prior to delivery and reset to 21% 6–8 h after birth. The control group was kept at 21% during the procedure. Reduced (GSH) and oxidized (GSSG) glutathione and its precursors [γ-glut…
Alcione e l'alcione. Archeologia del mito: nuclei tematici, funzioni simboliche, storia di contaminazioni
2021
Lo studio prende in considerazione le più antiche testimonianze della letteratura greca riguardanti il mito di Alcione e dell’uccello omonimo, per tentare di enuclearne funzione culturale e nuclei tematici originari. Rientrano nel quadro dell’analisi considerazioni sulla figura di Cleopatra Alcione in Hom. Il. 9, 561, sulle stratificazioni del mito post-omeriche con particolare riguardo per la tradizione esiodea del mito, con un’analisi del fr. 26 Davies di Alcmane (cerili e alcioni) nonché del fr. 508 Page di Simonide, quest’ultimo valutato rispetto agli aspetti ornitologici del mito (i giorni alcionii). Chiude l’indagine una proposta di interpretazione etimologica del nome Alcione (connes…
La resistenza di interfaccia calcestruzzo poroso-terreni a grana fina per il consolidamento di pendii mediante trincee drenanti profonde
2022
Le trincee drenanti profonde rappresentano uno dei metodi più efficaci per la mitigazione del rischio da frana, in pendii con falda idrica. Esse sono realizzate mediante pannelli o pali secanti. Il riempimento è costituito di calcestruzzo poroso o materiale granulare. Se le trincee sono adeguatamente “innestate” nel terreno stabile e il materiale di riempimento ha sufficiente resistenza e rigidezza come il calcestruzzo poroso, si ha ulteriore in-cremento di resistenza a taglio per effetto shear keys, oltre a quello derivante dalla riduzione delle pressioni in-terstiziali. L’incremento di resistenza è dovuto sia alla resistenza all’interfaccia calcestruzzo–terreni sia a quella intrinseca del…
