The dynamics of the extreme right support: A growth curve model of the populist vote in Flanders-Belgium in 1987-2007 KU Leuven
In the last 20 years, extreme right parties have gained a substantial share of electorate in a number of Western European countries. Despite of substantial research interest, the reasons for the popularity of the Extreme Right parties presented in the studies are often contradictory. Our study has a two-fold contribution to the topic. First, we show that studies based on aggregate data analysis may yield biased results that are not confirmed ...
The impact of education and intergroup friendship on the development of ethnocentrism. A latent growth curve model analysis of a five year panel study among Belgian late adolescents KU Leuven
In this paper, we investigate individual level changes in ethnocentrism during adolescence and pre-adulthood. We use structural equation modeling for longitudinal designs on data from the Belgian Political Panel Survey (BPPS, 2006-2011). In this panel, 2,428 Belgian adolescents were questioned at three points in time: at the ages of 16, 18 and 21. Individual change is analyzed by using Latent Growth Curve Modeling. Individual variability was ...
Divergent selection for shape of growth curve in Japanese quail. 4. Carcase composition and thyroid hormones KU Leuven
1. Changes in the relative weights of carcase, abdominal fat, breast and leg muscles, and plasma thyroid hormone concentrations occurring during the first 6 weeks of postnatal growth were analysed in males of HG and LG lines divergently selected for high and low relative body weight (BW) gain between 11 and 28 d of age, respectively, and constant adult BW. 2. The second week of postnatal life was a critical age at which the HG males exhibited a ...
A growth curve to model changes in sport participation in adolescent boys KU Leuven
The aims of this study are twofold: (1) to present the latent growth model, its strategy and usefulness in modelling sport participation over a 6-year period in youngsters (2) and to study the impact of biological maturation in sport participation changes. A standardized sport participation questionnaire using h/week/year as the unit of analysis was applied to 588 Belgium boys 13-18 years of age followed longitudinally for 6 years. Skeletal age ...
Growth in virologically suppressed HIV positive children on antiretroviral therapy: individual and population-level references KU Leuven
Background Combination antiretroviral therapy (ART) suppresses viral replication in HIV-infected children. The growth of virologically suppressed children on ART has not been well documented. We aimed to develop dynamic reference curves for weight-for-age z scores (WAZ) and height-for-age z scores (HAZ). Methods Children aged <11 years at ART initiation with continuously undetectable viral loads (<400 copies/ml) treated at seven South ...
Time-course of the tDCS antidepressant effect : an individual participant data meta-analysis Universiteit Gent
Introduction: Prefrontal transcranial direct current stimulation (tDCS) shows promise as an effective treatment for depression. However, factors influencing treatment and the time-course of symptom improvements remain to be elucidated. Methods: Individual participant data was collected from ten randomised controlled trials of tDCS in depression. Depressive symptom scores were converted to a common scale, and a linear mixed effects individual ...
Individual differences in training gains and transfer measures Universiteit Antwerpen
Currently, evidence for the beneficial effects of working memory (WM) training on transfer measures in children with attention-deficit/hyperactivity disorder (ADHD) is inconsistent. Although there is accumulating evidence for the role of individual differences in training and transfer gains of cognitive training, this area has been left unexplored for children with ADHD. In the current study, an advanced latent growth curve model analysis was ...
A principled method to identify individual differences and behavioral shifts in signaled active avoidance KU Leuven
Signaled active avoidance (SigAA) is the key experimental procedure for studying the acquisition of instrumental responses toward conditioned threat cues. Traditional analytic approaches (e.g., general linear model) often obfuscate important individual differences, although individual differences in learned responses characterize both animal and human learning data. However, individual differences models (e.g., latent growth curve modeling) ...
Determinants of female adolescents’ quality of life before, during and after detention : a four-wave follow-up study examining a theory of individual quality of life Universiteit Gent
Quality of Life (QoL) has become an important indicator of health care needs and treatment outcomes. Yet studies on this topic among detained girls are still very scarce. This study aimed to fill this void by examining a theory of individual QoL, focussing on determinants of detained girls’ QoL over time. A four-wave follow-up study was conducted among 147 detained girls (Mage = 16.20). Participants rated their self-perceived QoL (i.e., physical ...
