COVID-19 Lockdown
2022
Purpose: To investigate differences in athletes’ knowledge, beliefs, and training practices during COVID-19 lockdowns with reference to sport classification and sex. This work extends an initial descriptive evaluation focusing on athlete classification. Methods: Athletes (12,526; 66% male; 142 countries) completed an online survey (May–July 2020) assessing knowledge, beliefs, and practices toward training. Sports were classified as team sports (45%), endurance (20%), power/technical (10%), combat (9%), aquatic (6%), recreational (4%), racquet (3%), precision (2%), parasports (1%), and others (1%). Further analysis by sex was performed. Results: During lockdown, athletes practiced body-weigh…
Coaches' reflections on the meaning and value of Masters athletics
2019
Masters sport is a growing social movement offering the opportunity to participate in competitive sports in later life. Although many studies have explored Masters athletes' experiences, little is known about how other actors in the sport subcultures construct meaning in Masters sport and whether their stories work to support or hinder participation. Our study explored the cultural narrative resources and life scripts surrounding sport and ageing that coaches draw upon in two European countries, England and Finland, where sport policy has put different emphasis on elite sport and sport for all. We analysed interviews from 23 athletics (track and field) coaches (8 women) to understand how th…
Sprint Conditioning of Junior Soccer Players: Effects of Training Intensity and Technique Supervision
2015
The aims of the present study were to compare the effects of 1) training at 90 and 100% sprint velocity and 2) supervised versus unsupervised sprint training on soccer-specific physical performance in junior soccer players. Young, male soccer players (17 ± 1 yr, 71 ± 10 kg, 180 ± 6 cm) were randomly assigned to four different treatment conditions over a 7-week intervention period. A control group (CON, n = 9) completed regular soccer training according to their teams' original training plans. Three training groups performed a weekly repeated-sprint training session in addition to their regular soccer training sessions performed at A) 100% intensity without supervision (100UNSUP, n = 13), B)…
Human newborns match tongue protrusion of disembodied human and robotic mouths
2011
International audience; No evidence had been provided so far of newborns' capacity to give a matching response to 2D stimuli. We report evidence from 18 newborns who were presented with three types of stimuli on a 2D screen. The stimuli were video-recorded displays of tongue protrusion shown by: (a) a human face, (b) a human tongue from a disembodied mouth, and (c) an artificial tongue from a robotic mouth. Compared to a baseline condition, neonates increased significantly their tongue protrusion when seeing disembodied human and artificial tongue movements, but not when seeing a 2D full-face protruding tongue. This result was interpreted as revealing the exploration of top-heavy patterns o…
Setting-up tension in the style of Marantaceae
2008
The Marantaceae stand out from other plant families through their unique style movement which is combined with a highly derived form of secondary pollen presentation. Although known for a long time, the mechanism underlying the movement is not yet understood. In this paper, we report an investigation into the biomechanical principles of this movement. For the first time we experimentally confirm that, in Maranta noctiflora, longitudinal growth of the maturing style within the 'straitjacket' of the hooded staminode involves both arresting of the style before tripping and building up of potential for the movement. The longer the style grows in relation to the enclosing hooded staminode, the m…
Insights Into the Inside - A Quantitative Histological Study of the Explosively Moving Style in Marantaceae.
2018
This study aims to identify the histological basis for the extraordinary, fast movement of the style in Marantaceae. Although this explosive pollination mechanism was subject of many studies, quantitative measurements to document volumetric changes have never been conducted. Based on physical parameters and limitations (poroelastic time), the movement itself is by far too fast to be explained by turgor changes solely. Therefore, we address the hypothesis that the style contains elastic structures to store energy allowing the fast movement. We provide an experimental approach in Goeppertia bachemiana to identify histological differences of styles in various states, i.e., steady, unreleased, …

Conservation, Spillover and Gene Flow within a Network of Northern European Marine Protected Areas
2013
Published version of an article in the journal: PLoS ONE. Also available from the publisher at: http://dx.doi.org/10.1371/journal.pone.0073388 Open access To ensure that marine protected areas (MPAs) benefit conservation and fisheries, the effectiveness of MPA designs has to be evaluated in field studies. Using an interdisciplinary approach, we empirically assessed the design of a network of northern MPAs where fishing for European lobster (Homarus gammarus) is prohibited. First, we demonstrate a high level of residency and survival (50%) for almost a year (363 days) within MPAs, despite small MPA sizes (0.5-1 km2). Second, we demonstrate limited export (4.7%) of lobsters tagged within MPAs…
Spatial Extent of vertical tectonic motions in northern Sicily using Holocene and Last Interglacial sea level markers: a case study between Acquedolc…
2010
Vertical position of sea-level, related deposits and morphologies (e.g., last interglacial, LIG, 125ka,) provide useful markers to utilize with this purpose (LAMBECK et alii, 2004; FERRANTI et alii, 2006, ANTONIOLI et alii, 2009). Using published (ANTONIOLI et alii, 2006) and new data we provide a review of the northern coast of Sicily uplift rates. The markers used in this study are: terraces inner margin, tidal notches, etc., and, for the last millennia archaeological markers and fossil beaches and vermetid reef. Data on vertical movements calculated for the coastal area developing in the north-Sicilian continental margin indicate that, from East to West, a strong variation of vertical ra…
Corporate Governance Configurations and Corporate Social Responsibility Disclosure: Qualitative Comparative Analysis of Audit Committee and Board cha…
2020
[EN] Drawing on the complexity theory and responding to the recent calls to use such creative methods that mix between a quantitative and qualitative approach. Therefore, this study fills the literature gap, adding novelties, showing evidence from the unexplored (or underexplored) European context and, consequently, shedding light to inconclusive results in previous research concerning the effect of audit committee (AC) and board characteristics on corporate social responsibility (CSR) disclosure by applying a novel research methodology: the fuzzy set qualitative comparative analysis. The data were collected from Eikon database for a sample of the top 69 non¿financial European companies (ba…
