The relationship between teachers' work motivation and classroom goal orientation
2018
We investigated the relationship between teachers’ work motivation and their self-reported endorsement of mastery goals - i.e. goals focusing on learning and effort-, instead of performance goals - i.e. goals focusing on competition-, in the classroom. 154 secondary school teachers in the Netherlands completed a questionnaire on background characteristics, work motivation, and classroom goal structures. We found that teachers with higher levels of autonomous motivation, scored high on their self-reported endorsement of mastery goals. Controlled motivation was a significant predictor of performance goals, but not of mastery goals. In contrast, autonomous motivation was found to be a small ye…
Genomic characterization of the Atlantic cod sex-locus
2016
AbstractA variety of sex determination mechanisms can be observed in evolutionary divergent teleosts. Sex determination is genetic in Atlantic cod (Gadus morhua), however the genomic location or size of its sex-locus is unknown. Here, we characterize the sex-locus of Atlantic cod using whole genome sequence (WGS) data of 227 wild-caught specimens. Analyzing more than 55 million polymorphic loci, we identify 166 loci that are associated with sex. These loci are located in six distinct regions on five different linkage groups (LG) in the genome. The largest of these regions, an approximately 55 Kb region on LG11, contains the majority of genotypes that segregate closely according to a XX-XY s…

Sample size planning of two-arm superiority and noninferiority survival studies with discrete follow-up
2016
In clinical trials using lifetime as primary outcome variable, it is more the rule than the exception that even for patients who are failing in the course of the study, survival time does not become known exactly since follow-up takes place according to a restricted schedule with fixed, possibly long intervals between successive visits. In practice, the discreteness of the data obtained under such circumstances is plainly ignored both in data analysis and in sample size planning of survival time studies. As a framework for analyzing the impact of making no difference between continuous and discrete recording of failure times, we use a scenario in which the partially observed times are assig…
Influence of GSM signals on human peripheral lymphocytes: study of genotoxicity.
2013
Exposure to radiofrequency (RF) electromagnetic fields (EMF) is continuously increasing worldwide. Yet, conflicting results of a possible genotoxic effect of RF EMF continue to be discussed. In the present study, a possible genotoxic effect of RF EMF (GSM, 1,800 MHz) in human lymphocytes was investigated by a collaboration of six independent institutes (institutes a, b, c, d, e, h). Peripheral blood of 20 healthy, nonsmoking volunteers of two age groups (10 volunteers 16-20 years old and 10 volunteers 50-65 years old) was taken, stimulated and intermittently exposed to three specific absorption rates (SARs) of RF EMF (0.2 W/kg, 2 W/kg, 10 W/kg) and sham for 28 h (institute a). The exposures…
Psychobiosocial States as Mediators of the Effects of Basic Psychological Need Satisfaction on Burnout Symptoms in Youth Sport
2020
Sport participation in youngsters has been associated with long-lasting psychosocial and health-related benefits as well as increased levels of physical exercise in adulthood. The objective of this study was to examine some psychological factors of fundamental importance in enhancing sport participation and preventing burnout. A sample of 520 girls and boys aged 13–18 years, practicing individual or team sports, took part in a cross-sectional study to assess basic psychological need satisfaction, psychobiosocial states, and burnout symptoms. The specific purpose was to examine the mediation effects of emotion-related (i.e., functional/dysfunctional) psychobiosocial states on the relationshi…

The Father in Youth Baseball: A Self-Determination Theory Approach
2021
This study based on the self-determination theory aims to examine the relationship among the aspirations that fathers have about their children’s youth baseball practice, the children’s basic psychological needs (satisfaction and frustration), and their intentions to either continue or drop out of baseball practice in a sample of children from Hermosillo, Mexico. A cross-sectional study was carried out involving 533 fathers (M = 44.30, SD = 5.18) and 533 children (M = 13.09, SD = 1.68). The results showed that the intrinsic aspirations of fathers were positively correlated to the satisfaction of the children’s psychological needs, whereas the extrinsic aspirations of fathers were positively…
Effects of a School-Based Intervention on Motivation for Out-of-School Physical Activity Participation.
2020
Purpose: We tested the effects of an autonomy-supportive intervention in physical education (PE) on high-school students’ autonomous motivation in PE, and their autonomous motivation, intentions, a...
Applying the trans-contextual model to promote sport injury prevention behaviors among secondary school students.
2021
The current study tested the effects of an intervention based on the trans-contextual model (TCM) on secondary school PE students' sport injury prevention behavior and on theory-based motivational and social cognition mediators. Participants were PE students (N = 1168; Mage = 13.322 ± 1.045, range = 12-16; female = 51.721%) who participated in a 3-month cluster-randomized controlled trial. Schools were randomly assigned to a treatment group, in which PE teachers received training to be more supportive of psychological needs in teaching sport injury prevention, or a control group, in which PE teachers received no training. Participants completed survey measures of TCM variables and self-rep…
