Local scale high frequency monitoring of seaweed strandings along an intertidal shore of the English Channel (Luc-sur-Mer, Normandy France) – Effect of biotic and abiotic factors

Seaweed strandings on Luc-sur-Mer beach (Bay of Seine, English Channel, France) were monitored from March2017 to October 2018 once or twice a week to investigate the wrack deposit dynamics linked to biotic andenvironmental parameters. The extent of stranded seaweed, algal biomass and composition of algal wrack weremonitored through 99 field surveys. Forty-seven macroalgae taxa (14 Phaeophyta, 28 Rhodophyta, and 5Chlorophyta) were identified in strandings. Almost 83% of the 35 taxa (8 Phaeophyta, 23 Rhodophyta, and 4Chlorophyta) inventoried on the nearby intertidal rocky shore during the same period were also identified in thewrack deposits, suggesting their local origin. Analysis of wrack composition revealed the dominance of sheet-likespecies and annual algae mainly represented by Ulva in spring and summer, and by perennial and brown sea-weeds in winter. The same stranding dynamics was observed in the two years with largest deposits in spring andsummer but strandings occurred earlier in 2017, due to contrasted environmental parameters in the two years.Large wrack deposits (> 4.5 Ha) were mainly observed in spring when the wind speed was greater than 2.6 m.

Dynamics of δ15N isotopic signatures of different intertidal macroalgal species: Assessment of bioindicators of N sources in coastal areas

International audienceδ15N of annual (Ulva sp., Porphyra sp.) and perennial intertidal seaweed species (Chondrus crispus, Fucus sp.) collected on 17 sampling points along the French coast of the English Channel in 2012 and 2013 were assessed on their suitability as bioindicators of N pollution in coastal areas. A sine function applied for δ15N time series data showed for all the species the same seasonal trend with lowest δ15N values in April and highest in summer but with no significant interspecific differences of amplitude (α) and phase angle (ϕ). This model provides a useful tool for monitoring the inter-annual changes of N pollution. An interspecific variability of δ15N values was observed, probably due to their tolerance to emersion. An in vitro study for comparing the kinetic acquisition of the isotopic signal and N uptake mechanisms of each species underlined the influence of algal physiology on the δ15N interspecific variability

L’invention de la gestion des finances publiques

Le vote et la mise en œuvre de la loi organique relative aux lois de finances du 1er août 2001 ont rappelé l’importance de la régulation et de la gestion des finances publiques. Pour ses promoteurs, la LOLF introduirait de manière inédite des préoccupations managériales dans le droit budgétaire et comptable, volontiers présenté comme peu soucieux de considérations d’efficacité ou d’efficience. Cette actualité de la LOLF incite l’historien, le juriste ou le politiste à prendre de la distance en réinscrivant ces mutations dans la longue durée. À travers une série d’études inédites, cet ouvrage retrace l’histoire mal connue des principes, des règles, des instruments et des pratiques qui ont façonné le droit budgétaire et compta ble tout au long du XIXe siècle, depuis sa refondation sous la Restauration jusqu’au début de la Première Guerre mondiale. Comment et à travers quels enjeux sont produites les normes du droit budgétaire et comptable ? Quels débats de doctrine suscitentelles ? Que nous apporte la perspective historique pour (re)penser les relations entre la mise en place d’un droit des finances publiques et les préoccupations gestionnaires ? Quelles pratiques ce droit génère-t-il ? Telles sont les grandes questions auxquelles s’efforce de répondre ce livre sur la période 1815-1914. Les analyses et hypothèses avancées dans l’ouvrage sont issues de la confrontation féconde de plusieurs champs disciplinaires, l’histoire, le droit et la science politique. Premier tome d’une « Histoire de la gestion des finances publiques de 1815 à nos jours », ce volume contribue à une histoire de l’État qui s’inscrit au cœur d’un dialogue passé-présent et qui suit le fil riche et complexe du développement de la gestion des finances publiques.The passing and the implementation of the constitutional bylaw on budget acts [LOLF] of 1 August 2001 reminded us of the importance of the regulation and management of public finances. For its sponsors, the LOLF was an unprecedented move to introduce managerial concerns into budgetary and accounting law, readily presented as caring little for effectiveness or efficiency. As the LOLF is relatively recent, this prompts historians, law specialists or political analysts to take the longer view, by putting these changes into perspective. Through a series of groundbreaking studies, this work traces the little known history of the principles, the rules, the instruments and the practices which moulded budgetary and accounting law throughout the course of the 19th century, from the time it was recast under the Reformation up to the beginning of the First World War. How were the rules of budgetary and accounting law developed and which issues helped to form them? What debates on legal theory have they provoked? How does the historical perspective help us to think about (or to re-think) the relationship between the introduction of a public finance law and managerial concerns? What sort of practices does this law give rise to? These are the major questions which this book covering the period 1815-1914 attempts to answer. The analyses and hypotheses put forward in this work are the result of a fruitful debate between several disciplines: history, law and political science. As the first volume in a series entitled ‘Histoire de la gestion des finances publiques de 1815 à nos jours’ [History of public finance management from 1815 to the present], this book is a contribution towards the history of the State, which lies at the heart of the dialogue between the past and the present, and which traces the rich and complex history of the development of public financial management.La votación y puesta en vigor de la Ley Orgánica relativa a las Leyes de Presupuestos (LOLF) de 1 de agosto de 2001 recordaron la importancia de la regulación y gestión de las finanzas públicas. Para sus impulsores, esta LOLF tuvo como novedad el introducir criterios gestores en el derecho presupuestario y contable, a menudo presentado como poco preocupado por consideraciones de eficacia o eficiencia. Esta actualidad de la LOLF invita al historiador, el jurista o el politólogo a tomar distancia enmarcando dichos cambios en el largo plazo. La obra retoma así una serie de estudios inéditos para trazar la historia mal conocida de los principios, reglas, mecanismos y prácticas que a lo largo del s. XIX, desde su refundación en tiempos de la Restauración hasta el estallido de la I Guerra Mundial, fueron dando forma al derecho presupuestario y contable. Cómo e impulsadas por qué desafíos se fueron forjando las normas del derecho presupuestario y contable; qué debates disciplinarios abren; qué nos aporta la perspectiva histórica para (re)pensar las relaciones entre la puesta en vigor de un derecho de las finanzas públicas y las preocupaciones propias del gestor; qué prácticas genera dicho derecho… Éstas son las grandes cuestiones a las que el libro intenta dar respuesta durante el periodo 1815-1914. Los análisis e hipótesis expuestos en la obra son el fruto de la fértil confrontación entre varios campos disciplinarios: la historia, el derecho y la ciencia política. Primer tomo de una “Historia de la gestión de las finanzas públicas desde 1815 a nuestros días”, este volumen es la aportación a una historia del Estado que se inscribe en el núcleo mismo del diálogo entre el pasado y el presente y que sigue el hilo rico y complejo del desarrollo de la gestión de las finanzas públicas.La mission du département Histoire économique et financière de l’Institut de la gestion publique et du développement économique est de contribuer à une meilleure connaissance de l’histoire de l’État et de son rôle en matière économique et financière depuis le Moyen Âge jusqu’à nos jours, de susciter des travaux scientifiques et d’en aider la diffusion. Le Comité pour l’histoire économique et financière de la France est rattaché à l’Institut de la gestion publique et du développement économique, il a pour mission de l’assister dans ses activités de recherches historiques

Neuropsychological outcome after carbon monoxide exposure following a storm: a case-control study.

International audienceBACKGROUND: The cognitive consequences of carbon monoxide (CO) poisoning are well described. However, most studies have been carried out without an ad-hoc group of control subjects. The main aim of this study was to evaluate cognitive and psychiatric outcome after CO exposure during the storm Klaus in the South West of France (January 2009) in a homogeneous group of patients compared to a group of 1:1 paired controls. METHODS: Patients and controls were asked to fill out questionnaires about quality of life and cognitive complaints. They then underwent a cognitive assessment derived from the Carbon Monoxide Neuropsychological Screening Battery. Psychiatric assessment was performed using subtests of the Mini International Neuropsychiatric Interview. RESULTS: 38 patients and 38 paired controls were included (mean age 38.8 years) and evaluated 51 days after the poisoning. No difference was found between groups on the cognitive complaint questionnaire but patients had a lower quality of life than controls. Patients showed significantly lower cognitive performance than controls on processing speed, mental flexibility, inhibition and working and verbal episodic memories. Patients were more depressed than controls, and suffered more from post-traumatic stress disorder. CONCLUSIONS: We report the first study investigating cognitive and psychiatric outcome in consecutive patients after CO poisoning during a natural disaster, using a group comparison method. CO poisoning during storms needs to be dealt with adequately and clinicians should be aware of its possible consequences
