La "Nueva Filología" de Ortega: de su teorización histórico-conceptual a su praxis
2021
La filosofía de José Ortega y Gasset está marcada por una clara voluntad de estilo, que es personalísima y creativa. Este modo de pensar la filosofía vinculado a su desarrollo estético y retórico se muestra en las diferentes figuras literarias a las que recurría constantemente, como las metáforas o las etimologías. La intuición de que la filosofía precisa de un ejercicio anterior, el filológico, para realizar su tarea atraviesa todo su pensamiento. La tradición humanista y Nietzsche lo habían puesto en esta coordenada según la cual la filosofía debe empezar en el quehacer filológico. Hay una necesidad filológica, Platón había dicho “necesidad logográfica”, para vertebrar la filosofía y des-…
Restitusjonsvaner hos unge toppidrettsutøvere i Sør-Norge : En kartleggingsstudie av utholdenhet- og ballspillutøvere
2018
Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2018 Background: In order to perform optimally in training and competition, the recovery inbetween, through adequate diet and sufficient sleep/rest, is of great importance. Up until now, most studies have only featured adult athletes. Similarly, studies conducted on young athletes, as well as across sports, are limited. Purpose: The purpose of this study was to assess the habits of recovery, in terms of diet and sleep, with regards to the recommendations given by Helsedirektoratet and Olympiatoppen. Further investigating the use of different recovery strategies, among young elite athletes in southern Norway. Method: A total of 36 …

Behaviour of Extractives in Norway Spruce (Picea abies) Bark during Pile Storage
2022
The current practices regarding the procurement chain of forest industry sidestreams, such as conifer bark, do not always lead to optimal conditions for preserving individual chemical compounds. This study investigates the standard way of storing bark in large piles in an open area. We mainly focus on the degradation of the most essential hydrophilic and hydrophobic extractives and carbohydrates. First, two large 450 m3 piles of bark from Norway spruce (Picea abies) were formed, one of which was covered with snow. The degradation of the bark extractives was monitored for 24 weeks. Samples were taken from the middle, side and top of the pile. Each sample was extracted at 120 °C with both n-h…
Pašefektivitātes un sociālā atbalsta saistība ar uztverto stresu dažādu intensitāšu fizisko aktivitāšu grupās
2019
Pētījuma mērķis: Izpētīt saistību starp uztverto stresu, pašefektivitāti, uztverto sociālo atbalstu un dažāda veida fizisko aktivitāšu veikšanu. Koens un Heilija parādīja sociālā atbalsta un pašefektivitātes pozitīvo ietekmi uz dzīves kvalitāti. Turklāt sociālajm atbalstam var būt labvēlīga ietekme uz veselību briesmu laikā, jo notiek buferizācija stresa situācijām (Haugland, Wahl, Hofoss, DeVon, 2016). Teorētiskā asociācija starp stresu, paškontroli un sociālo atbalstu ir sabiedrībā plaši pētīta. Kā piemēram, kad indivīdiem ir augsta paškontroles sajūta (t.i. ticība spējai pašam ietekmēt savas dzīves notikumus) un saskarsme ar stresu izraisošām situācijām, tie ir tendēti uz aktīvu darbību …
Frequency and Density-Dependent Selection on Life-History Strategies - A Field Experiment
2008
Negative frequency-dependence, which favors rare genotypes, promotes the maintenance of genetic variability and is of interest as a potential explanation for genetic differentiation. Density-dependent selection may also promote cyclic changes in frequencies of genotypes. Here we show evidence for both density-dependent and negative frequency-dependent selection on opposite life-history tactics (low or high reproductive effort, RE) in the bank vole (Myodes glareolus). Densitydependent selection was evident among the females with low RE, which were especially favored in low densities. Instead, both negative frequency-dependent and density-dependent selection were shown in females with high RE…
Oppilaiden näkemykset keskiössä : kyselytutkimus oppilaiden osallisuudesta
2017
Tutkimuksessa selvitettiin erään keskisuomalaisen koulun oppilaiden näkemyksiä osallisuudesta. Tässä tutkimuksessa keskiössä olivat oppilaiden näkemykset heidän mielipiteensä huomioinnista päätöksenteossa ja mahdollisista eroista eri ryhmien kesken. Lisäksi selvitettiin oppilaiden näkemyksiä oppilaskunnan hallituksesta, asioista, joihin he haluaisivat vaikuttaa jatkossa ja mielipiteen ilmaisuun kannustamisesta koulussa. Tiedon saaminen käytännön tason osallisuudesta on ajankohtaista, sillä osallisuutta on pyritty edistämään kouluissa mm. uusissa perusopetuksen opetussuunnitelmien perusteissa. Kyselytutkimukseen osallistui noin kolmasosa koulun oppilaista (N = 117). Sähköisen kyselylomakkeen…
Referee efficacy in the context of Norwegian soccer referees – A meaningful construct?
2018
Abstract Objectives The purpose of this study was two-fold. Firstly, to examine the measurement/factorial validity and invariance of the Referee Self-Efficacy Scale (REFS) among Norwegian soccer referees. Secondly, extending scale validation, we also tested a structural model in which a second-order version of the REFS was modelled to mediate a set of theoretically informed antecedents and outcomes. Design Cross-sectional. Method One hundred and eleven Norwegian elite referees and 81 non-elite referees completed an electronic questionnaire measuring expected antecedents and outcomes of perceived self-efficacy in the role as referees. Results Analyses provided support for the first – and sec…
Adaption and validation of the German version of the basic psychological needs in physical education scale
2013
It is important to understand students’ motivation regarding physical activity to investigate the global issue physical inactivity. Based on the self-determination theory (SDT: Ryan & Deci, 2002), which is one of the most important frameworks in explaining motivation, students need to be emotionally satisfied in order to put effort towards a certain goal. The Basic Psychological Needs Theory is one sub-theory of the self-determination theory, which explains that constructs of autonomy, competence, and relatedness need to be satisfied in all humans in order to increase well-being. It is important to understand students’ motivation regarding physical activity to investigate the global issue o…
