Using Heart Rate Variability Methods for Health-Related Outcomes in Outdoor Contexts : A Scoping Review of Empirical Studies
2023
Heart rate variability (HRV) is a psychophysiological variable that is often used in applied analysis techniques to indicate health status because it provides a window into the intrinsic regulation of the autonomic nervous system. However, HRV data analysis methods are varied and complex, which has led to different approaches to data collection, analysis, and interpretation of results. Our scoping review aimed to explore the diverse use of HRV methods in studies designed to assess health outcomes in outdoor free-living contexts. Four database indexes were searched, which resulted in the identification of 17,505 candidate studies. There were 34 studies and eight systematic reviews that met t…
Ultra-High Energy Neutrinos at the Pierre Auger Observatory
2013
The observation of ultrahigh energy neutrinos (UHE nu s) has become a priority in experimental astroparticle physics. UHE nu s can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going nu) or in the Earth crust (Earth-skimming nu), producing air showers that can be observed with arrays of detectors at the ground. With the surface detector array of the Pierre Auger Observatory we can detect these types of cascades. The distinguishing signature for neutrino events is the presence of very inclined showers produced close to the ground (i.e., after having traversed a large amount of atmosphere). In this work we review the procedure and …
Experimental Constraints on the Deep Magma Feeding System at StromboliVolcano, Italy
2009
International audience; New experiments have been performed on a high-K basalt (PST-9) from Stromboli volcano, Italy, to constrain the physical conditions of golden pumice magmas at their storage level and discuss their petrogenesis. Fluid-present, H2O- and CO2-bearing, near-liquidus experiments were performed at 11508C between 100 and 400MPa and under oxidizing conditions. Glasses were analyzed by Fourier transform IR spectroscopy and their H2O and CO2 concentrations compared with those in glass inclusions.Most glass inclusions cluster near the 200MPa isobar, suggesting entrapment at a depth of ~8 km. Golden pumice magmas have viscosities of 7.9 Pa s and densities of 2.48-2.57 g/cm3. Compo…
Ultra-high temperature metamorphism recorded in Fe-rich olivine-bearing migmatite from the Khondalite Belt, North China Craton
2018
International audience; We document the first occurrence of Fe‐rich olivine‐bearing migmatitic metapelite in the Khondalite Belt, North China Craton. Petrological analyses revealed two exotic assemblages of orthopyroxene+spinel+olivine and orthopyroxene+spinel+cordierite. Phase relation modelling suggests that these assemblages are diagnostic of ultra‐high temperature (UHT) metamorphism in the Fe‐rich system, with temperatures from 1,000 to 1,050°C at 0.6 GPa. U–Th–Pb SIMS analyses on zircon reveal a similar age of c. 1.92 Ga for the olivine‐bearing migmatite and an adjacent gabbronoritic intrusion that is therefore identified as the heat source for the UHT metamorphism. These results, coup…
Alteration-Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)
2021
International audience; Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability. We present a study that combines laboratory experiments, geophysical data, and large-scale numerical modeling to better understand the influence of alteration on volcano stability, using La Soufrière de Guadeloupe (Eastern Caribbean) as a case study. Laboratory experiments on variably altered (advanced argillic alteration) blocks show that uniaxial compressive strength, Young's modulus, and cohesion decrease as a function of increasing alteration, but that …
Estetica urbana. Atmosfere e artificazione degli spazi della città
2023
Ancora uno studio su questo argomento, infatti i pochi saggi su temi analoghi non adottano una prospettiva filosofica. Il volume mira a colmare questa lacuna affrontando l’estetica urbana attraverso due paradigmi interpretativi, che talvolta nel libro vengono intrecciati: i concetti di atmosfera e di artificazione. La nozione di “atmosfera” nasce in seno alla nuova fenomenologia tedesca di Hermann Schmitz ed è declinata verso l’estetica dal filosofo Gernot Böhme che la considera un paradigma privilegiato per indagare gli spazi emozionali, intesi come frutto di relazioni affettive tra il soggetto percipiente e l’oggetto percepito. Pertanto l’estetica delle atmosfere si rivela uno strumento t…
More nature in the city
2020
According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
Ti år med EQ i skolen : en case-studie av forholdet mellom EQ og måloppnåelse i skolen
2016
Masteroppgave ledelse ORG917 - Universitetet i Agder 2016 Purpose and Research The goal of this thesis has been to find out to what extent the systematic introduction of "EQ in school" has succeeded, and in which areas. I have also focused on finding out through theory and examination of a selected unit whether EQ has a connection with achievement. For Norwegian schools to be able to adopt new methods that promote a positive in-school learning environment, it is important that those responsible can make informed decisions, and that information on new methods are based on research and results. According to Norwegian school researcher Thomas Nordahl, the learning environment is crucial for st…
Darbaspēka struktūra potenciālas darbavietu automatizācijas apstākļos
2020
Tehnoloģiskajam progresam arvien paātrinoties, jautājums par automatizācijas ietekmi uz darbaspēku kļuvis arvien aktuālāks. Pētījuma mērķis ir apzināt Latvijas darbaspēka struktūru potenciālas darbavietu automatizācijas apstākļos un noskaidrot, kā profesijas automatizācijas varbūtība korelē ar darba samaksu Latvijā. Pētījumā izmantotas divas pieejas sniedz ļoti atšķirīgus rezultātus. Saskaņā ar uzdevumos balstīto pieeju augsts automatizācijas potenciāls raksturo 11% Latvijas darbavietu, bet profesijā balstītās pieejas rezultāti liecina, ka riskam pakļauts 43% Latvijas darbavietu. Tāpat secināts, ka grūti automatizējamas profesijas kopumā raksturo būtiski plašāks darba samaksas diapazons, ne…
