Rapid sensing of volcanic SO₂ fluxes using a dual ultraviolet camera system: new techniques and measurements at Southern Italian volcanoes
2012
Volatiles carry crucial information on pre- to sin-eruptive processes at active volcanoes. Measurements of gas emission rates (crater plumes, fumaroles, diffuse soil degassing) therefore improve our understanding of degassing processes and subsurface magmatic and hydrothermal conditions, and contribute to eruption forecasting. Recent technological developments in spectroscopy have allowed, over the last 30 years, the remote sensing of magmatic volatile emissions from quiescent and erupting degassing volcanoes. These data-sets have contributed to discovering cyclic gas flux components due to periodic magma supply and replenishment in magma storage zones, and/or timescales of magma migration …
Els canvis del discurs nacionalista espanyol com a conseqüència de l'auge de Vox
2021
L’actualitat política i social del nostre país ens porta necessàriament a parar atenció en l’auge del partit ultradretà Vox. Aquest partit va sorgir al desembre del 2013, com a conseqüència de les disputes internes del Partit Popularoriginades per l’erosió del partit arrelde la crisi econòmica del 2008. No obstant, no va ser fins a les eleccions andaluses del 2018 que Vox va aconseguir representació parlamentaria (llevat d’algunes eleccions d’àmbit local on va obtenir alguns regidors al 2015) tot i haver-se presentat sistemàticament. En aquest treball es fa una anàlisi del discurs de Vox a les seues xarxes socials per tal d'observar de quina manera contribueix als canvis en el discurs nacio…
Miten opettaja rakentaa pedagogisen auktoriteetin? Otteita opettajan arjesta
2002
Laadullisen tutkimuksen päätavoitteena oli pureutua siihen, miten opettaja ymmärtää ja rakentaa pedagogisen auktoriteettinsa koulun arjessa. Koska auktoriteettisuhde ei todennu ajatuksissa, puheessa ja kuvitelmissa, tutkin myös, miten auktoriteetti toimii ja saa oikeutuksen luokkatilanteessa. Pedagoginen auktoriteetti liitetään taustakirjallisuudessa toisaalta varsinaisen vallankäytön ulkopuoliseen, kasvatukseen liittyvään auktoriteettisuhteeseen, toisaalta korostetaan henkilösuhteen merkitystä auktoriteettisuhteen muotoutumisessa. Työn peruskysymys on sama kuin työn nimi: Miten opettaja rakentaa pedagogisen auktoriteetin? Osakysymyksiä ovat seuraavat: Mitä ilmiöön pedagoginen auktoriteetti…

The Effects of Cold Water Immersion on the Recovery of Drop Jump Performance and Mechanics : A Pilot Study in Under-20 Soccer Players
2020
Cold water immersion (CWI) is a popular method used for enhancing recovery from exercise. However, the efficacy of this approach is inconclusive and studies investigating variables contributing to overall performance are scarce. Additionally, few studies have investigated the recovery of stretch-shortening cycle (SSC) performance after a fatiguing SSC task. The SSC occurs naturally in human locomotion and induces a recovery pattern different from isolated muscle contractions (e.g., pure eccentric exercise). Therefore, the main aim of this study was to investigate the effects of a single CWI on jumping performance and mechanics after exhaustive SSC exercise. On a sledge apparatus, 10 male un…
Hip and wrist accelerometers showed consistent associations with fitness and fatness in children aged 8‐12 years
2020
Aim. Physical activity (PA) has traditionally been measured wearing accelerometers on the hip, but they are increasingly being worn on the wrist. We compared hip and wrist accelerometers with regard to their acceptability and any associations between PA and fatness and fitness. Methods. This cross‐sectional study comprised 103 children aged 8‐12 years (62% boys) who participated in the ActiveBrains trial by the University of Granada, Spain, in 2014‐2016. The children wore both ActiGraph GT3X+ hip and wrist accelerometers round the clock for seven days. The acceptability of both placements was evaluated by a questionnaire, while the children' fat mass index, waist circumference, and cardiore…
The effect of aquatic exercise on symptoms, function, body composition and cartilage in knee osteoarthritis
2016
Knee osteoarthritis (OA) is the most common joint disease associated with pain and loss of functional capacity. The management of knee OA is multifaceted and covers the whole OA continuum from injury prevention to the end stage of the disease. Recently, specific focus has been on preventing the progression of cartilage degeneration and avoiding loss of function in the early phase of the disease via the provision of exercise interventions. Aquatic exercise is a popular but under-researched exercise option. Therefore, the purpose of this dissertation was to investigate the role of aquatic exercise in the management of knee OA, focusing especially the effect it evokes on both functional capaci…
Effects of Physical and Cognitive Training on Gait Speed and Cognition in Older Adults : A Randomized Controlled Trial
2021
Gait speed is a measure of health and functioning. Physical and cognitive determinants of gait are amenable to interventions, but best practices remain unclear. We investigated the effects of a 12‐month physical and cognitive training (PTCT) on gait speed, dual‐task cost in gait speed, and executive functions (EFs) compared to physical training (PT) (ISRCTN52388040). Community‐dwelling older adults, who did not meet physical activity recommendations, were recruited (n=314). PT included supervised walking/balance (once weekly) and resistance/balance training (once weekly), home exercises (2‐3 times weekly) and moderate aerobic activity 150 minutes/week in bouts of >10 minutes. PTCT included …

Inspiratory Muscle Strength and Cardiorespiratory Fitness Association With Health-Related Quality of Life in Healthy Older Adults
2021
The main purpose of this study was to explore similarities and differences in the association between two capabilities affecting the cardiorespiratory system (overall and multifactorial cardiorespiratory fitness and inspiratory muscle strength) and the health-related quality of life (HRQoL), in a group of active healthy seniors. Sixty-five individuals (age, 73.01 ± 5.27 years; 53 women) who participated regularly in a multicomponent training program completed the EuroQol 5D-5L questionnaire, the 6-min walking test (6MWT), and the maximum inspiratory pressure test (MIP). Non-parametric correlations (Spearman's rho) were conducted to analyze the association between HRQoL indices (EQindex and …
