    Interest in independent schools has been growing in Canada, partly as a result of some parental dissatisfaction with public schools. The Canadian province of Alberta has legislation in place that permits development of independent schools while simultaneously imposing controls on their operations. A recent study used interviews, observations, and documents to examine the perceptions of principals in eight accredited, funded, independent schools in Alberta about the major factors that affected their leadership role. They especially identified philosophical congruence enhanced by respect and trust, as well as personal relationships, school culture, symbolism, and support from staff of the government's regional offices.Au Canada, on manifeste de plus en plus d'intĂ©rĂȘt dans les Ă©coles indĂ©pendantes; il s'agit d'un phĂ©nomĂšne qui est en partie dĂ» Ă  la l'insatisfaction que certains parents ressentent vis-Ă -vis des Ă©coles publiques. Dans la province de l'Alberta (Canada), la lĂ©gislation actuelle permet l'Ă©tablissement d'Ă©coles indĂ©pendantes tout en imposant certains contrĂŽles quant Ă  leur fonctionnement.

    (Certified) Humane Violence? Animal Production, the Ambivalence of Humanizing the Inhumane, and What International Humanitarian Law Has to Do with It

    Get PDF
    The chapter draws a comparison with the self-certifying of production methods as ‘humane’ or animal-friendly in the labelling of animal products—that is, according to companies’ own self-imposed codes of conduct. It likens the idea of humanizing animal slaughter, factory farms, and other forms of production to the notion of humanizing warfare. Like international humanitarian law (IHL), animal welfare law is marked by the tension inherent in its attempt to humanize innately inhumane practices. Given these parallels, the analysis of animal welfare law might benefit from existing insights into the potential and limits of IHL. Both areas of law endorse a principle of ‘humanity’ while arguably facilitating and legitimizing the use of violence, and might thereby ultimately perpetuate the suffering of living beings. The implicit justification of violence percolating from the IHL-like animal ‘protection’ laws could only be outweighed by complementing this body of law with a ius contra bellum for animals

    Biodiversity conservation: local and global consequences of the application of “rights of nature” by Ecuador

    Get PDF
    In 2008, Ecuador recognized the Constitutional Rights of Nature in a global first. This recognition implies a major shift in the human-nature relationship, from one between a subject with agency (humans) and an exploitable object (nature), to a more equilibrated relationship. However, the lack of a standard legal framework has left room for subjective interpretations and variable implementation. The recent widespread concessioning of pristine ecosystems to mining industries has set up an unprecedented conflict and test of these rights. Currently, a landmark case involving Los Cedros Protected Forest and mining companies has reached the Constitutional Court of Ecuador. If Ecuador’s highest Court rules in favor of Los Cedros and the Rights of Nature, it would set a legal precedent with enormous impact on biological conservation. Such a policy shift offers a novel conservation strategy, through citizen oversight and action. A ruling against Los Cedros and the Rights of Nature, while a major setback for biodiversity conservation, would be taken in stride by the active social movement supporting these goals, with the case likely moving into international courts. Meanwhile, extractive activities would continue and expand, with known consequences for biodiversity

    Lightweight convolutional neural network for real-time 3D object detection in road and railway environments

    International audienceFor smart mobility, and autonomous vehicles (AV), it is necessary to have a very precise perception of the environment to guarantee reliable decision-making, and to be able to extend the results obtained for the road sector to other areas such as rail. To this end, we introduce a new single-stage monocular real-time 3D object detection convolutional neural network (CNN) based on YOLOv5, dedicated to smart mobility applications for both road and rail environments. To perform the 3D parameter regression, we replace YOLOv5’s anchor boxes with our hybrid anchor boxes. Our method is available in different model sizes such as YOLOv5: small, medium, and large. The new model that we propose is optimized for real-time embedded constraints (lightweight, speed, and accuracy) that takes advantage of the improvement brought by split attention (SA) convolutions called small split attention model (Small-SA). To validate our CNN model, we also introduce a new virtual dataset for both road and rail environments by leveraging the video game Grand Theft Auto V (GTAV). We provide extensive results of our different models on both KITTI and our own GTAV datasets. Through our results, we show that our method is the fastest available 3D object detection with accuracy results close to state-of-the-art methods on the KITTI road dataset. We further demonstrate that the pre-training process on our GTAV virtual dataset improves the accuracy on real datasets such as KITTI, thus allowing our method to obtain an even greater accuracy than state-of-the-art approaches with 16.16% 3D average precision on hard car detection with inference time of 11.1 ms/image on an RTX 3080 GPU.Pour la mobilitĂ© intelligente, et les vĂ©hicules autonomes (VA), il est nĂ©cessaire d'avoir une perception trĂšs prĂ©cise de l'environnement pour garantir une prise de dĂ©cision fiable, et de pouvoir Ă©tendre les rĂ©sultats obtenus pour le secteur routier Ă  d'autres domaines comme le ferroviaire. À cette fin, nous introduisons un nouveau rĂ©seau de neurones convolutif (CNN) monoculaire de dĂ©tection d'objets 3D en temps rĂ©el basĂ© sur YOLOv5, dĂ©diĂ© aux applications de mobilitĂ© intelligente pour les environnements routiers et ferroviaires. Pour effectuer la rĂ©gression des paramĂštres 3D, nous remplaçons les boĂźtes d'ancrage de YOLOv5 par nos boĂźtes d'ancrage hybrides. Notre mĂ©thode est disponible dans diffĂ©rentes tailles de modĂšles comme YOLOv5 : petit, moyen et grand. Le nouveau modĂšle que nous proposons est optimisĂ© pour les contraintes de l'embarquĂ© en temps rĂ©el (lĂ©gĂšretĂ©, vitesse et prĂ©cision) qui tire profit de l'amĂ©lioration apportĂ©e par les convolutions d'attention fractionnĂ©e (SA) appelĂ© petit modĂšle d'attention fractionnĂ©e (Small-SA). Pour valider notre modĂšle CNN, nous introduisons Ă©galement un nouvel ensemble de donnĂ©es virtuelles pour les environnements routiers et ferroviaires en exploitant le jeu vidĂ©o Grand Theft Auto V (GTAV). Nous fournissons des rĂ©sultats dĂ©taillĂ©s de nos diffĂ©rents modĂšles Ă  la fois sur KITTI et sur nos propres jeux de donnĂ©es GTAV. Nous montrons que notre mĂ©thode est la plus rapide pour la dĂ©tection d'objets en 3D, avec une prĂ©cision proche de celle des mĂ©thodes les plus avancĂ©es sur le jeu de donnĂ©es KITTI. Nous dĂ©montrons Ă©galement que le processus de prĂ©-entraĂźnement sur notre jeu de donnĂ©es virtuel GTAV amĂ©liore la prĂ©cision sur les jeux de donnĂ©es rĂ©els tels que KITTI, permettant ainsi Ă  notre mĂ©thode d'obtenir une prĂ©cision encore plus grande que les approches de l'Ă©tat de l'art avec 16,16% de prĂ©cision moyenne 3D sur la dĂ©tection de voitures avec un temps d'infĂ©rence de 11,1 ms/image sur un GPU RTX 3080
