In elite sports, a case is increasingly made for the structural inclusion of what we label as planned disruptions. These are structured and deliberate training activities whereby athletes are exposed to increased and/or changing demands under controlled circumstances. Despite the growing body of evidence in support of planned disruptions (Sarkar & Fletcher, 2017), there is a lack of knowledge on which strategies coaches use in an applied context and why they use them. The present study, therefore, aimed at exploring the different types of planned disruptions high-performance coaches use and the desired outcomes of these disruptions. To this end, thematic analysis (Braun, Clarke, & Weate, 2016) was used to analyze semistructured interviews with 9 talent development and elite-level coaches (M age = 42.9, SD = 8.3; 6 male, 3 female). Results indicated that coaches use a combination of 9 types of planned disruptions (i.e., location, competition simulation, punishments and rewards, physical strain, stronger competition, distractions, unfairness, restrictions, and outside the box). These strategies were used to familiarize athletes to pressure, create awareness, develop or refine personal resources, and promote team processes. Three additional themes emerged, namely, the surprise use of planned disruptions, periodization, and the impact on personal relationships. The findings in the present study can guide further applied and theoretical explorations of the use of planned disruptions.
Like many countries, the COVID-19 pandemic has forced Statistics Netherlands to make changes in its fieldwork strategy. Since mid-March 2020, there have been limited opportunities to conduct face-to-face interviews. Therefore, from September 2020, CAPI sampled people are offered the opportunity to respond by telephone. For this purpose, face-to-face interviewers are instructed to persuade the potential respondent at the doorway. When people refuse a face-to-face interview, interviewers ask for a telephone number and try to make an appointment to conduct the interview by telephone. The aim of our study was to investigate the effects of conducting the interview by telephone instead of face-to-face on important survey outcome variables. We were particularly interested in whether differences are due to selection effects or caused by mode-specific measurement errors. Because we did not have the time or capacity to set up a controlled experiment, we performed regression analyses to decompensate the differences between selection effects and mode-specific measurement errors. We used data of the Labour Force Survey (LFS) and the Housing Survey (WoON). Our analysis showed that there were differences in important target variables, for both LFS and WoON. These differences were, however, mainly caused by selection effects – which can be taken into account for during weighting – and were less likely to be caused by mode specific measurement errors. Although there are important limitations and caveats, these findings are supportive to further implement this field strategy.
For a number of years now, NGO Milieu Centraal has been running the website www.klimaatwijsopreis.nl, which informs Dutch consumers about the climate impact of holidays and also allows them to calculate the climate impact of their own holiday. This calculator is based on, among other things, a number of calculation models and a series of emission factors for transport, accommodation, activities, and holiday types. These emission factors are subject to change and should be updated regularly. This project provides an update and substantiation of emission factors for a number of accommodation types, activities, and holiday types.Societal issueThe contribution of holidays to climate change is substantial, depending on choices regarding transport, distance, accommodation, and activities.Benefit to societywww.klimaatwijsopreis.nl informs consumers about the climate impact of holidays, so they can make more informed choices. Up to date and sound emission factors enable giving the most accurate advice.
