DEVELOPMENT AND QUALIFICATION OF BIOANALYTICAL METHODS FOR DEAMIDATED IFNβ-1a AND INVESTIGATION ABOUT THE MECHANISM OF ACTION
2021
Interferon beta-1a (IFNβ-1a) is a recombinant IFNβ with the tradename Rebif involved in several biological activities. Recently, it has been reported that artificial deamidation of IFNb-1a increases its biological response. Given the therapeutical potential, an investigation on the deamidated variant has been carried out via different approaches to discover the mechanism underlying this biological effect. The antiviral and immunomodulatory activity of deamidated cytokine was assessed using two precise and accurate cell-based assays. As expected, deamidated IFNβ-1a showed an increase in the biological response and its canonical pathway and receptor binding affinity were thorough analysed. De…
Snacktivity™ to promote physical activity and reduce future risk of disease in the population: protocol for a feasibility randomised controlled trial…
2023
Abstract Background Many people do not regularly participate in physical activity, which may negatively impact their health. Current physical activity guidelines are focused on promoting weekly accumulation of at least 150 min of moderate to vigorous intensity physical activity (MVPA). Whilst revised guidance now recognises the importance of making small changes to physical activity behaviour, guidance still focuses on adults needing to achieve at least 150 min of MVPA per week. An alternative ‘whole day’ approach that could motivate the public to be more physically active, is a concept called Snacktivity™. Instead of focusing on achieving 150 min per week of physical activity, for example …
Teenage Time Use and Educational Attainment in Adulthood in Finland
2021
We investigated the role of teenage everyday social ties in educational outcomes by examining the association between teenage time use and educational attainment in adulthood. The sample consisted of young people aged 10–18 from the 1979 Finnish Time Use Survey, and the same respondents’ educational attainment later in life recorded from population register data at the year of 40th birthday (n = 366 men and 393 women). We assessed the associations of time spent with the parents, on studying, leisure activities, as well as social connectedness with friends and participation in extracurricular activities, with educational outcomes. Our findings indicated that time spent with the father is pos…
Integrating Self-Reports and Electrodermal Activity (EDA) Measurement in Studying Emotions in Professional Learning
2022
Studies on emotions in learning have been mostly conducted through self-reporting questionnaires and interviews conducted after the learning situation, which seldom focus on professional workplace learning. Meanwhile, workplace and professional learning research has been introduced with emerging methods to capture the learning processes at multiple levels. Previous research on emotions has suggested that self-reports should be supplemented with psychophysiological data. Challenged by this, this chapter aims to present and discuss the integration of self-reported and psychophysiological data in studying emotions and professional learning. The empirical research data are obtained from five Fi…
Being active in pregnancy : Theory-based factors associated with physical activity among pregnant women
2019
Although regular physical activity is recommended for pregnant women, compared to pre-pregnancy, antenatal physical activity often reduces or ceases completely. Drawing from the theory of planned behavior, self-determination theory, and theory on self-control, we aimed to test an integrative model of physical activity in a sample of pregnant women. The current study was conducted in Brisbane, Australia, in 2014–2015 using a prospective-correlational design with a one-week follow-up. Participants (N = 207, Time 1; Meanage = 30.03 years, SDage = 4.49 years) completed an initial survey measuring: intrinsic motivation from the self-determination theory, social cognitive constructs from the theo…
Application of the trans-contextual model to predict change in leisure time physical activity
2021
Objective: This study tested effects of changes in the psychological constructs of the trans-contextual model (TCM) on changes in adolescents' outside of school moderate-to-vigorous physical activity (PA) measured using self-report and accelerometer-based device. Design: A three-wave longitudinal design was used. High school students (N = 331) completed measures of all the TCM constructs at Time1 and at Time2, five weeks apart. Self-reported PA behaviour was measured also at Time3, five weeks after Time2. PA was measured using accelerometer-based devices for seven days following Time1 and Time3 for a census week. Results: A structural equation model using residual change scores revealed tha…
Student intention to engage in leisure-time physical activity: The interplay of task-involving climate, competence need satisfaction and psychobiosoc…
2018
Grounded in achievement goal theory and basic psychological needs theory, the aim of this study was to examine the impact of the interaction of perceived motivational climate in physical education with psychological needs satisfaction (relatedness, competence and autonomy) and psychobiosocial states on student intention to engage in leisure-time physical activity. Participants ( N = 470 Italian students, 287 boys and 183 girls, aged 16–19 years) completed the Teacher-Initiated Motivational Climate in Physical Education Questionnaire, the Psychological Needs Satisfaction Scale in Physical Education, the Psychobiosocial States Questionnaire, and a measure of intention to engage in leisure-tim…
Testing a physical education-delivered autonomy supportive intervention to promote leisure-time physical activity in lower secondary school students:…
2020
© 2020 The Author(s). Background: Inadequate physical activity in young people is associated with several physical and mental health concerns. Physical education (PE) is a potentially viable existing network for promoting physical activity in this population. However, little research has been conducted on whether PE teachers can influence students' engagement in leisure-time physical activity. The present study therefore examined the efficacy of an intervention aimed at increasing PE teachers' autonomy support on students' leisure-time physical activity (the PETALS trial). The intervention was guided by the trans-contextual model (TCM) explaining the processes by which PE teachers' provisio…
Romanian educational system - component of the national economy
2009
National economy as a stand-alone entity, is a set of resources (natural, material, human, etc..), production activities, trade, service etc. that have established branches, sectors, etc. at a country’s level, between which are established reciprocal links which is based on the material and spiritual movement values, ensures the operation and economic development of society. Thus, the national economy’s system appears as a set of interconnected elements through economic, educational, informational, technological, cultural, etc. relations according to a predetermined goal, or serving the same goal.
STRATEGIC ROLE OF ACTIVITY IN THE EFFECTIVE MANAGEMENT OF A COMPANY FROM THE SME SECTOR IN THE ERA OF GLOBAL CRISIS
2012
The year 2009 ended in Poland and other EU countries under the sign of the Great Depression, which began on the other side of the ocean but it covered almost the whole world. The most vulnerable to the crisis turned out to be companies from the SME sector which, in the European Union SMEs represent 99.8% companies operating within the Union, and their sales account for about 56.2% total revenues. EU small and medium-sized companies employ more than 66% workforce and they are the ones most heavily affected by the crisis. In Poland the company from the SME sector accounts for over 90% of all businesses operating in our country. And they were faced in front of the huge challenge which was how …
