The importance of psychological variables in the perceived exertion of young football players
2017
Las escalas para medir la percepción del esfuerzo están entre los métodos que han sido utilizados para el control y la evaluación de la carga interna del entrenamiento en deportes de equipo como el fútbol. Debido a su naturaleza psicofisiológica, su registro proporciona información proveniente tanto de indicadores fisiológicos como psicológicos del deportista. Dentro del marco de la Teoría de la Autodeterminación (SDT, Self Determination Theory; Deci & Ryan, 1985; Ryan & Deci, 2017) y de la Teoría de las Metas de Logro (AGT, Achievement Goal Theory; Ames, 1992; Nicholls, 1989), en esta tesis doctoral se estudian tanto las variables contextuales desadaptativas (dimensiones del clima motivaci…
Students' self-determined motivation in physical education and intention to be physically active after graduation : the role of perceived competence …
2014
Purpose: This study examined whether high school students' degree of self-determined motivation in school physical education predicted their intentions to be physically active after graduation, and whether perceived physical competence and physical activity identity mediated this hypothesized cross-sectional relationship. Additionally, the possibility of conditional effects of gender on these associations was considered. Method: A cross sectional study involving 1650 high-school students allowed for the examination of indirect effects using a bias-corrected bootstrapping technique. Results: Results showed that self-determination in PE may positively affect adolescents' intentions to be phys…
The Basic Psychological Needs in Physical Education Scale in Filipino: An Exploratory Factor Analysis
2014
Fulfillment of students’ basic psychological needs in school physical education is essential for their optimal motivation and well-being. The present study aimed to: (1) translate the Basic Psychological Needs in Physical Education Scale (BPNPE Scale; Vlachopoulos, Katarzi, & Kontou, 2011) to Filipino, and (2) examine the reliability and validity of the Filipino version. Instrument translation was conducted using a committee-approach back-translation procedure. The Filipino version was then administered to 408 public high school students from Metro Manila during one of their PE classes. Results showed that internal consistency reliabilities of the subscales were adequate with alphas ranging…
Weryfikacja kinetycznego modelu polimeryzacji etylenu wobec metaloorganicznych katalizatorów wanadowych na nośniku magnezowym
1998
The kinetic studies are reviewed on low-pressure polymerization of ethylene over two types of organovanadium catalysts, viz., MgCl 2(THF) 2/VCl 4/Et 2AlCl and MgCl 2(THF) 2VOCl 3Et 2AlCl, each deposited on a magnesium carrier. The polymerization rate was found to be directly related to the catalyst and monomer concentrations (Figs. 2 and 3), unless when the access of the monomer to the reactive V-C bond is restricted by diffusion. Polymer chain termination step was found to result from the reaction of the transfer onto the monomer and to be associated with the regeneration of the active site on which a new macromolecule can be formed. A kinetic model was developed for the ethylene polymeriz…
The economic causes of the failure of the "socialist" system
1994
Le but de ce travail est de démontrer pourquoi les pays qui se prétendaient socialistes n'ont pas atteint leurs deux principaux objectifs: justice sociale et démocratie. En ce qui concerne le premier, dans ces pays, l'organisation de la production et la détermination des prix, centralement planifiés, nepermettaient pas toujours de réaliser la production en fonction de l'utilité sociale. Cette façon de déterminer les prix engendre une demande sans offre qui se révèle être, d'une part, une cause de dysfonctionnement du système car le marché ne joue pas alors l'un de ses principaux rôles qui est detransmettre l'information aux responsables de la production, d'autre part, une cause d'insatisfac…
KOSMOS 2017 Peru Side Experiment: nutrients, phytoplankton abundances, enzyme rates, photophysiology
2022
This data was collected during an short-term incubation experiment in March 2017 that investigated the response of a surface plankton community to upwelling. This experiment was carried in the framework of the SFB754-funded KOSMOS mesocosm study that took place in La Punta, Callao, Peru between February-April 2017. A total of six different treatments were used to disentangle chemical and biological characteristics of deep water that influence surface plankton blooms: 2 different deep water sources with different nutrient concentrations; 3 treatments to distinguish the effects of inorganic nutrients, organic nutrients and deep water microbial populations. Measured variables include inorganic…
Prejudice and need for relatedness expressed in the narratives of Finnish Roma early school leavers: A multi-case study
2023
AbstractSchool discontinuation in Finland is more common among the Finnish Roma than among the population as a whole. We lack knowledge of the perspective of those of the Roma, representing a minority inside a minority, who have left compulsory school without a leaving certificate. Within a study about school experiences of imprisoned early school leavers in Finland we had six participants with a Finnish Roma background, whose experiences of relatedness, and frustration of it, we examine in this paper. We conducted narrative interviews with the participants, applying a co-operative narrative interpretation to the meanings of what was told. After the field process, we interpreted the narrati…
Revisiting the Narratives of Finnish Early School Leavers: Mapping Experiences of Detachment through a Self-determination Theory Lens
2022
Basic psychological needs and people’s experiences affect the choices they make, and further shape the trajectories followed through school. The present study focuses on the perspectives of people who left school without graduating. Through narrative interviewing processes we collected the storied experiences of eleven imprisoned early school leavers in Finland. We triangulated data-driven themes and used as theory the concept of three basic psychological needs: autonomy, competence, and relatedness. Of these, relatedness was the most common and a shared topic brought forth by the participants. Experiencing dissatisfaction and frustration as a result of the need for relatedness played a cru…

La normativa emergenziale in materia di obbligazioni e di contratti
2020
Il saggio esamina le principali disposizioni in materia di obbligazioni e di contratti introdotte dalla normativa emergenziale al fine di fronteggiare la pandemia di Covid-19 e tenta di ricondurle a sistema. Più nel particolare, molte delle norme esaminate, a dispetto della loro natura eccezionale, non fanno che applicare istituti del diritto generale delle obbligazioni e dei contratti, come l’impossibilità definitiva o temporanea, la risoluzione per impossibilità, la revisione volontaria del contratto etc. Di particolare interesse - anche per l’impatto applicativo - si rivelano le questioni relative alla gestione dei rapporti contrattuali di durata e ai riflessi delle misure restrittive de…
