Can the tumble turn performance be improved by aligning the push-off force vector to the centre of mass trajectory? Open
The freestyle tumble turn is a critical element of competitive swimming, because an effective push-off from the wall combined with proper body alignment may contribute significantly to overall performance. Previous analyses have focused on…

An investigation of the emittance of escaping fast electron beams from planar and nanowire targets Open
Fast electron generation and transport in high-intensity laser–solid interactions induces X-ray emission and drives ion acceleration. Effective production of these sources hinges on an efficient laser absorption into the fast electron popu…

Preference estimation from point allocation experiments Open
Point allocation experiments are widely used in the social sciences. In these experiments, survey respondents distribute a fixed total number of points across a fixed number of alternatives. This paper reviews the different perspectives in…

Implications of the choice of distance-based measures in assessing and investigating tumble turn performance Open
Although the tumble turn in swimming has been studied extensively, no consensus exists about which measure is best suited to capture its performance. The aim of this study was to better understand the implications of choosing a particular …

Improving tumble turn performance in swimming—the impact of wall contact time and tuck index Open
Race time can be shortened by improving turn performance in competitive swimming, but this requires insight into the optimal turn technique. The aim of the present study was to examine the effect of Wall Contact Time (WCT) and Tuck Index o…

Participatory value evaluation for the evaluation of flood protection schemes Open
Participatory Value Evaluation (PVE) is a new survey method which elicits citizens' preferences over the allocation of public budgets as well as their private income. In a PVE, citizens are asked to choose the best portfolio of projects gi…

Raadsleden in lokale rekenkamers: de gevolgen voor de doorwerking van rekenkameronderzoek Open
Counselors in local audit offices. The effects for the impact of audit investigation The Dutch minister of Home Affairs, Ronald Plasterk, has resolved to obligate municipalities to set up an independent audit office. Other variants of the …

Study of shock waves generation, hot electron production and role of parametric instabilities in an intensity regime relevant for the shock ignition Open
We present experimental results at intensities relevant to Shock Ignition obtained at the sub-ns Prague Asterix Laser System in 2012. We studied shock waves produced by laser-matter interaction in presence of a pre-plasma. We used a first …

LONG‐RUN VERSUS SHORT‐RUN PERSPECTIVES ON CONSUMER SCHEDULING: EVIDENCE FROM A REVEALED‐PREFERENCE EXPERIMENT AMONG PEAK‐HOUR ROAD COMMUTERS Open
Earlier studies on scheduling behavior have mostly ignored that consumers have more flexibility to adjust their schedule in the long run than in the short run. We introduce the distinction between long‐run choices of travel routines and sh…
