Visualizing individual dynamics:The case of a talented adolescent

Research on talent and performance development has primarily focused on inter-individual differences. However, research suggests that performance and the underlying determinants change over time, in an individual-specific dynamic way. This chapter illustrates a method to measure, understand, and visualize the performance- and psychosocial dynamics of a talented adolescent athlete. During one season, a talented tennis player filled out an online diary questionnaire twice a week. We visualized the results using R-scripts that we made openly available. This facilitated the interpretation of the athlete’s performance- and psychosocial dynamics, which are influenced by particular events in the athlete’s life. Altogether, the current study provides insight into how the adolescent and the context interact and mutually affect each other in successive iterations

Collecting marine litter during regular fish surveys

This report presents the results of the marine litter monitoring on the IBTS survey of 2014 and the BTS survey of 2013. Since 2013 marine litter is collected during the International Bottom Trawl Survey (IBTS) and Dutch Beam Trawl Survey (BTS) following a protocol developed by ICES. The composition and the distribution of the sea floor marine litter from the catch is analysed and the results are compared with the results from the IBTS and BTS surveys of last year
