Maternally‐transferred thyroid hormones and life‐history variation in birds
2022
1. In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early-phase embryonic development when embryos are not able to produce endogenous THs. Previous studies have shown that variation in maternal THs within the physiological range can influence offspring phenotype. 2. Given the essential functions of maternal THs in development and metabolism, THs may be a mediator of life-history variation across species. 3. We tested the hypothesis that differences in life histories are associated with differences in maternal TH transfer across species…
Initial validation of the Psychobiosocial States in Physical Education (PBS-SPE) scale
2018
The purpose of this cross-sectional investigation was to examine the item characteristics, factor structure, reliability, convergent validity, and nomological validity of the Psychobiosocial States in Physical Education (PBS-SPE) scale. In Study 1, a sample of 1,030 students (582 girls and 448 boys, 10 to 19-year-olds), drawn from middle or high schools, rated the intensity of the 20 items version of the PBS-SPE scale thinking about the feelings they had usually experienced in physical education classes. In Study 2, an additional sample of 1,025 students (578 girls, 447 boys, 10 to 19-year-olds), rated the 16 items of the final version of the scale. Two subsamples also completed an affectiv…
Motorisen oppimisen vaikeuden tunnistaminen ja tukeminen kouluympäristössä
2018
Motorisen oppimisen vaikeudella, kuten kehityksellisellä koordinaatiohäiriöllä (DCD), tarkoitetaan huomattavaa vaikeutta oppia uusia motorisia taitoja ja soveltaa jo opittuja taitoja uusiin tilanteisiin. Tämän tutkimuksen tarkoituksena oli kehittää opettajien käyttöön havainnointityökalu, joka auttaa tunnistamaan motorisen oppimisen vaikeuden esi- ja alkuopetusikäisillä lapsilla. Lisäksi tutkimus selvitti, miten opettajat voivat kouluympäristössä tukea lapsia, joilla on haasteita motorisessa oppimisessa. Tutkimus muodostui neljästä osatutkimuksesta. Ensimmäisessä tutkittiin systemaattisen kirjallisuuskatsauksen avulla maailmalla käytössä olevien havainnointilomakkeiden psykometrisiä ominais…

Design of New Polyaspartamide Copolymers for siRNA Delivery in Antiasthmatic Therapy
2020
Here, a novel protonable copolymer was realized for the production of polyplexes with a siRNA (inhibitor of STAT6 expression in asthma), with the aim of a pulmonary administration. The polycation was synthesized by derivatization of &alpha
Endocrine disrupters: the new players able to affect the epigenome
2015
Epigenetics represents the way by which the environment is able to program the genome; there are three main levels of epigenetic control on genome: DNA methylation, post-translational histone modification and microRNA expression. The term Epigenetics has been widened by NIH to include “both heritable changes in gene activity and expression but also stable, long-term alterations in the transcriptional potential of a cell that are not necessarily heritable.” These changes might be produced mostly by the early life environment and might affect health influencing the susceptibility to develop diseases, from cancer to mental disorder, during the entire life span. The most studied environmental i…

La crisis economica sufrida en los ultimos anos, y en concreto en Espana, ha transmitido una cierta desconfianza en la sociedad acerca del valor que posee la educacion para la integracion y promocion socio-laboral de los jovenes, asi como en relacion al impacto que esta tiene para prevenir de la exclusion social a lo largo de la vida. Por desgracia en Espana, aun en la actualidad, que se considera que la crisis economica esta en proceso de superacion, hay una gran cantidad de jovenes que se les identifica como “sobre - formados” y que no encuentran un empleo adecuado a su formacion. Unos acaban trabajando en empleos que requieren menor formacion academica, mientras que otros acaban en el p…
Bordón : revista de pedagogía
2014
Resumen tomado de la publicación. El artículo forma parte de un monográfico titulado : educación supranacional. Se analiza cómo, a partir de los discursos en materia de política educativa establecidos en torno a la literatura de género y a términos como “capacitación de género” y “equidad de género”, así como la consolidación de políticas de mainstreaming (transversalidad de la perspectiva de género) se lleva a reconocer, a través de la Educación Comparada, interesantes hallazgos en este ámbito de estudio e investigación, con un revelador estado de la cuestión supranacional. Desde el enfoque de los sistemas educativos actuales se legitiman, en efecto, las consecuencias de la política global…
External Developmental Assets and Positive Identity Among Emerging Adults in Norway, Romania, Slovenia, and Turkey
2021
The present study adopts The Developmental Assets and Positive Youth Development (PYD) perspectives which (in contrast to the deficit-based approaches which highlight risks and deficit in youth development) claim that young people have potencies to achieve optimal development if supported by their social environment. Extant research indicates that developmental assets are linked with a variety of thriving indicators. The present research aimed to contribute to the PYD research by examining the external developmental assets (support, empowerment, and boundaries and expectations) emerging adults (N= 2055; age range = 18–28) perceived in their social environment and the level of their positive…
