Interpersonal Neural Synchrony During Father–Child Problem Solving: An fNIRS Hyperscanning Study

Interpersonal neural synchrony (INS) has been previously evidenced in mother–child interactions, yet findings concerning father–child interaction are wanting. The current experiment examined whether fathers and their 5- to 6-year-old children (N = 66) synchronize their brain activity during a naturalistic interaction, and addressed paternal and child factors related to INS. Compared to individual problem solving and rest, father–child dyads showed increased INS in bilateral dorsolateral prefrontal cortex and left temporo-parietal junction during cooperative problem solving. Furthermore, the father’s attitude toward his role as a parent was positively related to INS during the cooperation condition. These results highlight the implication of the father’s attitude to parenting in INS processes for the first time.     

No Need to be Discrete: A Method for Continuous Time Mediation Analysis

Mediation is one concept that has shaped numerous theories. The list of problems associated with mediation models, however, has been growing. Mediation models based on cross-sectional data can produce unexpected estimates, so much so that making longitudinal or causal inferences is inadvisable. Even longitudinal mediation models have faults, as parameter estimates produced by these models are specific to the lag between observations, leading to much debate over appropriate lag selection. Using continuous time models (CTMs) rather than commonly employed discrete time models, one can estimate lag-independent parameters. We demonstrate methodology that allows for continuous time mediation analyses, with attention to concepts such as indirect and direct effects, partial mediation, the effect of lag, and the lags at which relations become maximal. A simulation compares common longitudinal mediation methods with CTMs. Reanalysis of a published covariance matrix demonstrates that CTMs can be fit to data used in longitudinal mediation studies.     

London is Just Around the Corner: Belgium,Britain and Sport

Answering the legitimate call for a more transnational approach to the history of sport in Europe, we seize upon the 2012 Olympic Games as an opportunity to look back on Belgo-British contacts in sport since the Middle Ages. Contextualising this history within the wider Belgo-British political, economic and cultural contacts is, indeed, much more revealing than recounting a superficial story about the three medals the Belgian Olympic delegation actually obtained in London. We illustrate that transnational flows and contacts – crucial to the shaping and diffusion of sport – are not always reflected at the level of the Olympic Games. The cases of cycle racing and soccer demonstrate the divergent adoption and adaptation processes of specific sporting disciplines in Belgium and Britain. At the end of the paper, we also reflect on David Cameron's competitive sport policy in primary education, and raise the question whether the dissipation of public funds for elite sport – to the detriment of ‘Sport for All’ – is still defendable in times of government budgetary scarcity.     

Impact of early code‐skill and oral‐comprehension training on reading achievement in first grade

In a 3‐year longitudinal study, we examined the relationships between oral language development, early training and reading acquisition on word‐identification and reading‐comprehension tests administered to a sample of 687 French children. Hierarchical linear models showed that both phonological awareness and oral comprehension at the age of 4 years were relevant to reading acquisition 2 years later. These two broad skills explained separate parts of the variance on both outcome measures, while revealing opposite effects: phonological skills explained more variance for alphabetic reading skills and oral comprehension explained more variance for reading comprehension. We also assessed the effects of two preschool training programmes focusing on either phonological awareness or comprehension skills. The results showed that phonological awareness training had a positive effect on alphabetic scores, and comprehension training had a positive effect on reading comprehension. These results provide insight into early oral instruction and contribute to the theoretical debate about the linguistic predictors of literacy acquisition.     

The Effects of Teachers’ Training on Pupils’ Achievement: The Case of Elementary Schools in France

This investigation examines the effects of teachers’ training on pupils’ achievement in French and mathematics. The aim of the research is to compare the effectiveness of three samples of elementary school teachers with different levels of experience and training. Using a multilevel model, the results demonstrate that training enhances the effectiveness of novice teachers. In addition, experience was also found to have a positive effect. Neither training nor experience have a significant effect on equity, defined as the capacity of reducing the initial gap between high and low achieving pupils.

Media-specific rate allocation in heterogeneous wireless networks

INTRODUCTION With the development of novel wireless tech- nologies and increasing available bandwidth, multi- media applications over wireless networks become attractive for both businesses and end users. Fast de- ployment of Wi-Fi HotSpots, increase in wireless coverage of remote habitable areas (Wi-Max, or wireless mesh networks), improved data services over the 2G cellular systems and the long awaited debut of 3G wireless services offer many potential and inter- operable communicatio…
