Prosodic Structure as a Parallel to Musical Structure

Funding for Open Access provided by the UMD Libraries Open Access Publishing Fund.What structural properties do language and music share? Although early speculation identified a wide variety of possibilities, the literature has largely focused on the parallels between musical structure and syntactic structure. Here, we argue that parallels between musical structure and prosodic structure deserve more attention. We review the evidence for a link between musical and prosodic structure and find it to be strong. In fact, certain elements of prosodic structure may provide a parsimonious comparison with musical structure without sacrificing empirical findings related to the parallels between language and music. We then develop several predictions related to such a hypothesis

The teaching of anatomy in Montpellier University during VIII centuries (1220–2020)

International audienceSince 1220 in Montpellier the human cadaver dissection had been used for the teaching of anatomy. In the first time the anatomy was based on animal knowledge. Vesalius student in Montpellier then in Italy, written the first book on human anatomy. Among teachers some of them made discoveries such as Pecquet on cisterna chyli, Vieussens on brain and hearth. Wax anatomy was used for teaching and Laumonier and B. Delmas presented some very nice pieces. Progressively a lot of anatomical preparations were exposed in a conservatory with 2330 human cadavers' dissections obtained during a lot of examinations. Anatomy and pathology were developed by Delpech about growing of bones with laws. In 1953 two anatomist surgeons, Rapp and Couinaud, described the segmentation of the liver with using techniques of corrosion. In the conservatory 250 corrosions of the livers are exposed, this is certainly the most numerous in the world and it represents a huge basis for surgery and liver transplantation. Since 1900 the teaching of anatomy continued with blackboard lectures and Human cadavers dissections. Therefore, a new approach of anatomy with computer is going to be used in the future

Settings of demersal longlines reveal acoustic cues that can inform toothed whales where and when to depredate

International audienceFishing boats produce acoustic cues while hauling longlines. These acoustic signals are known to be used by odontocetesto detect the fishing activity and to depredate. However, very little is known about potential interactions before hauling.This article describes the acoustic signature of the setting activity. Using passive acoustic recorders attached to the buoys oflonglines, this work demonstrates an increase in the ambient sound of 6dB re 1 lPa2 Hz1 within 2–7 kHz during the settingactivity. This could also be used as an acoustic cue by depredating species, suggesting that predators can detect longlinesas soon as they are set

Acoustic measurements of post-dive cardiac responses in southern elephant seals ( Mirounga leonina ) during surfacing at sea

International audienceMeasuring physiological data in free-ranging marine mammals remains challenging, owing to their far-ranging foraging habitat. Yet, it is important to understand how these divers recover from effort expended underwater, as marine mammals can perform deep and recurrent dives. Among them, southern elephant seals (Mirounga leonina) are one of the most extreme divers, diving continuously at great depth and for long duration while travelling over large distances within the Southern Ocean. To determine how they manage post-dive recovery, we deployed hydrophones on four post-breeding female southern elephant seals. Cardiac data were extracted from sound recordings when the animal was at the surface breathing. Mean heart rate at the surface was 102.4±4.9 beats.min(-1) and seals spent on average 121±20 s breathing. During these surface intervals, the instantaneous heart rate is increasing with time. Elephant seals are supposed to drastically slow their heart rate (bradycardia) while they are deep underwater, and increase it (tachycardia) during the ascent towards the surface. Our finding suggests that tachycardia continues while the animal stays breathing at the surface. Also, the measured mean heart rate at the surface was unrelated to the duration and swimming effort of the dive prior to the surface interval. Recovery (at the surface) after physical effort (underwater) appears to be related to the overall number of heart beats performed at the surface, and therefore total surface duration. Southern elephant seals recover from dives by adjusting the time spent at the surface rather than their heart rat

Soundscape analysis in the Southern Ocean using elephant seals as acoustic glider of opportunity

International audienceThe underwater ambient sound field contains quantifiable information about the physical and biological marine environment. Since 2011, we have been annually collecting underwater data over the migratory routes of bio-logged Southern Elephant Seal (SES). As done with classical underwater gliders, we extract from these data very high resolution (approximately 30 min/400 m) ocean ambient noise measurements. In this conference, we present an overall picture of the low-to-medium frequency (10–6000 Hz) ambient noise distribution and its variability in time and space at a regional scale within the Indian Ocean. We detail our methodology to extract robustly the measurements usually performed on ocean ambient noise, such as sound pressure level over different frequency bands and their statistical percentiles. Also, we present our first attempts of exploiting acoustic recordings from bio-logged SES to infer surface wind speed. Wind maps from the ASCAT satellite (IFREMER, France) were used to study correlation relations between surface wind speed and acoustic content (e.g., the ratio of sound pressure levels at 1 and 6 kHz). In complement, we test SVM and Neural Network methods to estimate the presence of different classes of winds (e.g., below and above 10 m/s) from underwater ocean noise

Do commercial fisheries display optimal foraging? The case of longline fishers in competition with odontocetes

International audienceDepredation in longline fisheries by odontocete whales is a worldwide growing issue, having substantial socio-economic consequences for fishers as well as conservation implications for both fish resources and the depredating odontocete populations. An example of this is the demersal longline fishery operating around the Crozet Archipelago and Kerguelen Island, southern Indian Ocean, where killer whales (Orcinus orca) and sperm whales (Physeter macrocephalus) depredate hooked Patagonian toothfish (Dissostichus eleginoides). It is of great interest to better understand relationships of this modern fishery with its environment. Thus, we examined the factors influencing the decision making process of fishers facing such competition while operating on a patch. Using optimal foraging theory as the underlying hypothesis, we determined that the probability captains left an area decreases with increasing fishing success whereas, in presence of competition from odontocete whales, it increases. Our study provides strong support that fishers behave as optimal foragers in this specific fishery. Considering that captains are optimal foragers and thus aim at maximising the exploitation of the resources, we highlight possible risks for the long-term sustainability of the local ecosystem

Identifying innovations produced by primary health care centers and evaluating their scalability: the SPRINT Occitanie cross-sectional study in France

International audienceAbstract Background Practice-based research is one of the levers identified by the World Health Organization (WHO) to strengthen primary health care. The scaling of health and social care innovations has the potential to reduce inequities in health and to expand the benefits of effective innovations. It is now rapidly gaining the attention of decision-makers in health and social care, particularly in high-income countries. To meet the challenge of declining numbers of primary care physicians in France, Multi-professional Healthcare Centers (MHC) were created to bring together medical and paramedical professionals. They are a source of innovation in meeting the health challenges facing our populations. Specific methodology exists to identify health innovations and assess their scalability. A working group, including end-users and specialists, has adapted this methodology to the French context and the University department of general practice of Montpellier-Nîmes (France) launched a pilot study in Occitanie, a French region. Objective To identify and evaluate the scalability of innovations produced in pluri-professional healthcare centers in the Occitanie region. Methods A pilot, observational, cross-sectional study was carried out. The SPRINT Occitanie study was based on a questionnaire with two sections: MHC information and the modified Innovation Scalability Self-Administered Questionnaire (ISSaQ), version 2020. The study population was all 279 MHC in the Occitanie region. Results 19.3% (54) of MHC in the Occitanie region, responded fully or incompletely to the questionnaire. Four out of 5 U-MHCs were represented. Five MHC presented multiple innovations. The average per MHC was 1.94 (± 2.4) innovations. 26% of them ( n = 9) had high scalability, 34% ( n = 12) medium scalability and 40% ( n = 14) low scalability. The main innovation represented (86%) were healthcare program, service, and tool. Conclusions In our cross-sectional study, a quarter of the innovations were highly scalable. We were able to demonstrate the importance of MHC teams in working on primary care research through the prism of innovations. Primary-care innovations must be detected, evaluated, and extracted to improve their impact on their healthcare system

Evidence of deep-sea interactions between toothed whales and longlines

International audienceToothed whales (odontocetes) feeding on fish caught on hooks in longline fisheries is a growing issue worldwide. The substantial impacts that this behaviour, called depredation, can have on the fishing economy, fish stocks and odontocetes populations, raise a critical need for mitigation solutions to be developed. However, information on when, where and how odontocete depredation occurs underwater is still limited, especially in demersal longline fisheries (fishing gear set on the seafloor). In the present study, we investigated depredation by killer whales (Orcinus orca) and sperm whales (Physeter macrocephalus) on demersal longlines in the French Patagonian toothfish fishery (Southern Ocean). Using a combination of animal-borne behavioural and longline-attached data loggers, we demonstrated that both species are able to depredate longlines on the seafloor. This study, therefore, suggests that odontocetes whales-longline interaction events at depth may be unrecorded when assessing depredation rates from surface observations during hauling phases only. This result has implications for the management of fisheries facing similar depredation issues as underestimated depredation rates may result in unaccounted fish mortality in fish-stock assessments. Therefore, while further research should be conducted to assess the extent of deep-sea whale-longline interaction events during soaking, the evidence that depredation can occur at any time during the whole fishing process as brought out by this study should be considered in future developments of mitigation solutions to the issue
