L'action privée en droit des pratiques anticoncurrentielles : pour un recours effectif des entreprises et des consommateurs en droits français et canadien

Regulation of competition is dualistic in France and Canada. On one side, public authority frame the market and impose sanction, if appropriate, to the practices contrary to existing legislation, and, on other side, the victims injured by antitrust practices, that is consumers and company, may bring a private procecussion based on the liability to obtain a compensation for the antitrust injury. They are respectively of public action and private action, also referred to as public enforcement and private enforcement of competition law. However, in the European Union, and particularly in France, the antitrust harm has no effective remedy. Indeed, in France, consumers had not, until the adoption of the collective redress, procedural means to access the judge of compensation. In addition, the French civil law proves too rigid to allow compensation for something as complex as the competitive harm. For its thinking about it, the French legislator has often turned to the Canadian and Quebec models to reform its bicentenary civil law. Indeed, the Quebec civil law is particularly flexible in disputes related to competition law. In addition, the Canadian Competition Act provides a right to compensation adapted to the constraints of the victims of anticompetitive practices. The author has sought to understand how the Canadian private enforcement mechanism works to assess whether this model, through the Quebec civil law, could inspire a reform of French civil law model adopted by the legislature in particular during the introduction of collective redress. The analysis is primarily civil law to allow a reading of private action that departs from conventional stereotypes of the American experience in this field. The ultimate goal of this comparison is to make effective use of the private businesses and consumers in French and Canadian rights following an injury resulting from a violation of anti-competitive practices.La régulation de la concurrence est dualiste en France et au Canada. D’un côté, des autorités publiques de régulation encadrent le marché et sanctionnent le cas échéant les pratiques contraires aux dispositions législatives en vigueur, et, d’un autre côté, les victimes de pratiques anticoncurrentielles, c'est-à-dire les consommateurs et les entreprises, peuvent intenter des poursuites privées sur le fondement d’une action en responsabilité civile afin d’obtenir la réparation du préjudice concurrentiel subi. Il s’agit respectivement de l’action publique et de l’action privée en matière de concurrence, qualifiées aussi de public enforcement et de private enforcement du droit de la concurrence. Cependant, dans l’Union européenne, et en France particulièrement, le préjudice concurrentiel reste sans réparation effective. En effet, en France, les consommateurs n’avaient pas, jusqu’à l’adoption de l’action de groupe, de moyen procédural d’accéder au juge de la réparation. De plus, le droit civil français se montre trop rigide pour permettre l’indemnisation d’un préjudice économique aussi complexe que le préjudice concurrentiel. Pour alimenter sa réflexion à ce sujet, le législateur français s’est souvent tourné vers les modèles canadien et québécois pour réformer son droit civil bicentenaire. En effet, le droit civil québécois se montre particulièrement souple dans les litiges liés au droit de la concurrence. De plus, la Loi sur la concurrence canadienne offre un droit à réparation adapté aux contraintes des victimes de pratiques anticoncurrentielles. L’auteur a ainsi cherché à comprendre comment fonctionne le mécanisme canadien de private enforcement pour évaluer si ce modèle, par le truchement du droit civil québécois, pourrait inspirer une réforme du modèle civiliste français adopté par le législateur notamment lors de l’introduction de l’action de groupe. L’analyse se situe principalement en droit civil pour permettre une lecture de l’action privée qui s’éloigne des stéréotypes classiques tirés de l’expérience américaine dans ce domaine. L’objectif ultime de cette comparaison est de rendre effectif le recours privé des entreprises et des consommateurs en droits français et canadien à la suite d’un préjudice découlant d’une violation du droit des pratiques anticoncurrentielles

Suivi scientifique de vingt-sept régénérations naturelles de chêne sessile et de hêtre en Ardenne: retour d'expérience

National audienceRégénérer naturellement le chêne apparaît très délicat en Ardenne et cela se traduit déjà par un déficit marqué de jeunes chênes au niveau régional. Afin de rechercher des solutions sylvicoles à ce problème, vingt-sept régénérations naturelles de hêtre et de chêne ont été suivies entre 2007 et 2011. L’analyse montre clairement les besoins en lumière des chênes par rapport aux hêtres et, surtout, l’importance d’effectuer des nettoiements afin de réduire les effets de la compétition des hêtres sur les chênes

Game species monitoring using road-based distance sampling in association with thermal imagers: a covariate analysis

Monitorización de especies cinegéticas utilizando el muestreo a distancia con base en una carretera, en combinación con imágenes termográficas: un análisis de covariables La monitorización de las poblaciones de especies cinegéticas es necesaria para evaluar adecuadamente las capturas de los cazadores, en zonas que carecen de los grandes depredadores naturales. Sin embargo, los gestores de la caza deben controlar diversas especies y a menudo carecen de un método de control con un diseño conveniente. Por lo tanto, la monitorización de diversas especies al mismo tiempo en áreas muy grandes podría ser eficaz desde el punto de vista de los costes y del tiempo. Estudiamos la influencia de diversos factores durante la monitorización de tres especies cinegéticas comunes (el jabalí, el corzo y el zorro rojo) utilizando un muestreo a distancia desde la carretera, en asociación con imágenes termográficas. Este examen piloto basado en 20 recuentos nocturnos en cinco lugares contrastantes estudió el efecto de diversas covariables (especie, termografía, observador, tamaño del grupo y tipo de hábitat) sobre las probabilidades de detección (dp). No se hallaron diferencias entre las imágenes termográficas (dpJENOPTIK: 0,186, dpFLIR: 0,193) y el tamaño de los grupos (dp1ind.: 0,243, dp2ind.: 0,259, dp> 2ind.: 0,223), pero sí entre los observadores (dpobs1: 0,207, dpobs2: 0,274, dpobs3: 0,159). También se observaron diferencias esperadas entre las especies (dpwild boar: 0,22, dproe deer: 0,35, dpred fox: 0,32) y entre los tipos de hábitat (dpforest: 0,27, dpedge: 0,74, dpopen: 0,35). Nuestros resultados demuestran que la detectabilidad de los equipos de termografía de bajo coste es similar a la de otros métodos caros, destacando nuevas posibilidades del uso de la termografía para los gestores de la caza. Aunque deberían realizarse ajustes en el diseño del estudio, nuestros hallazgos sugieren que la monitorización de múltiples especies a gran escala podría ser un método eficaz para las especies cinegéticas comunes.Monitorización de especies cinegéticas utilizando el muestreo a distancia con base en una carretera, en combinación con imágenes termográficas: un análisis de covariables La monitorización de las poblaciones de especies cinegéticas es necesaria para evaluar adecuadamente las capturas de los cazadores, en zonas que carecen de los grandes depredadores naturales.

However, game managers have to control several species and they often lack of an efficient and convenient survey design method. Monitoring several species at that same time over large areas could thus be cost– and time–effective. We tested the influence of several factors during monitoring of three common game species, (wild boar, roe deer and red fox, using road–based distance sampling in association with thermal imagers. This pilot survey based on 20 night counts in five contrasting sites studied the effect of several covariates (species, thermal imaging, observer, group size, and habitat type) on the detection probabilities (= dp). No differences were observed between thermal imagers (dpJENOPTIK: 0.186, dpFLIR: 0.193) and group sizes (dp1ind.: 0.243, dp2ind.: 0.259, dp> 2ind.: 0.223), but we found differences between observers (dpobs1: 0.207, dpobs2: 0.274, dpobs3: 0.159). Expected differences were also observed between species (dpwild boar: 0.22, dproe deer: 0.35, dpred fox: 0.32) and between habitat type (dpforest: 0.27, dpedge: 0.74, dpopen: 0.35). Our results show that the detectability of low cost thermal imaging equipment is similar to that of more expensive methods, highlighting new possibilities for the use of thermal imagery by game managers. Although adjustments should be made to the study design our findings suggest that large–scale multi–species monitoring could be an efficient method for common game species

Voltammetric Characterization of Redox-Inactive Guest Binding to Ln III [15-Metallacrown-5] Hosts Based on Competition with a Redox Probe

A novel competitive binding assay was implemented to monitor the binding of a redox inactive substrate to a redox inactive metallacrown host based on its competition with ferrocene carboxylate (FcC − ) using cyclic voltammetry (CV). First, the binding of FcC − to Ln III [15-MC Cu II ,N,L-pheHA -5] (LnMC) hosts was characterized by cyclic voltammetry. It was shown that the voltammetric half wave potentials, E 1/2 , shifted to more positive potentials upon the addition of LnMC. The explicit dependence of E 1/2 with the concentration of LnMC was used to determine the association constants for the complex. The FcC − binding strength decreased with larger central lanthanide metals in the LnMC hosts, and substantially weaker binding was observed with La III . X-ray crystallography revealed that the hydrophobic host cavity incompletely encapsulated FcC − when the guest was bound to the nine-coordinate La III , suggesting the LnMC’s ligand side chains play a substantial role in guest recognition. With knowledge of the MC-FcC − solution thermodynamics, the binding affinity of a redox inactive guest was then assessed. Addition of sodium benzoate to a LnMC and FcC − mixture resulted in E 1/2 shifting back to the value observed for FcC − in the absence of LnMC. The association constants between benzoate and LnMC’s were calculated via the competitive binding approach. Comparison with literature values suggests this novel assay is a viable method for determining association constants for host–guest systems that exhibit the proper electrochemical behavior. Notably, this CV competitive binding approach does not require the preparation of a modified electrode or a tethered guest, and thus can be generalized to a number of host–guest systems.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/77442/1/chem_200903015_sm_miscellaneous_information.pd

A survey on computational intelligence approaches for predictive modeling in prostate cancer

Predictive modeling in medicine involves the development of computational models which are capable of analysing large amounts of data in order to predict healthcare outcomes for individual patients. Computational intelligence approaches are suitable when the data to be modelled are too complex forconventional statistical techniques to process quickly and eciently. These advanced approaches are based on mathematical models that have been especially developed for dealing with the uncertainty and imprecision which is typically found in clinical and biological datasets. This paper provides a survey of recent work on computational intelligence approaches that have been applied to prostate cancer predictive modeling, and considers the challenges which need to be addressed. In particular, the paper considers a broad definition of computational intelligence which includes evolutionary algorithms (also known asmetaheuristic optimisation, nature inspired optimisation algorithms), Artificial Neural Networks, Deep Learning, Fuzzy based approaches, and hybrids of these,as well as Bayesian based approaches, and Markov models. Metaheuristic optimisation approaches, such as the Ant Colony Optimisation, Particle Swarm Optimisation, and Artificial Immune Network have been utilised for optimising the performance of prostate cancer predictive models, and the suitability of these approaches are discussed

Chronique – La conformité en droit pénal des affaires : l'exemple du droit de la concurrence

L'auteur aborde la question de la prise en compte des programmes de conformité par le droit criminel dans le domaine du droit des affaires en prenant comme exemple le droit de la concurrence. Il montre que si les autorités publiques tendent à valoriser l'utilisation de programmes de conformité par les entreprises, la répression des infractions économiques ne prend que très peu en compte les efforts de conformité des organisations
