Transcending sovereignty : locating Indigenous peoples in transboundary water law

All people rely upon water for life. Indigenous peoples are especially vulnerable to water conflicts and yet lack recognition in international water law. This thesis adopts Critical Race Theory to examine the intersection between transboundary water law, the doctrine of sovereignty and the international law of Indigenous peoples. The methodology adopted in this thesis includes: (i) a deconstruction of the UN Watercourse Convention and the doctrine of sovereignty; (ii) a review of Indigenous perspectives on sovereignty; and (iii) a proposal for the reconstruction of transboundary water law in a manner that recognizes the internationally affirmed rights of Indigenous peoples. A deconstruction of the UN Watercourse Convention and related discourse reveals that state-centric approaches to transboundary water law fail to recognize Indigenous peoples’ international rights or the pivotal role that Indigenous peoples’ traditional knowledge might play in transcending conflict. Case examples are provided (Columbia River and Tsangpo-Brahmaputra River) that illustrate the vulnerability of Indigenous peoples in the face of state development agreements. The inequities that exist in international water law are rooted in the historical doctrine of sovereignty which has evolved to subordinate Indigenous peoples’ interests to state interests. Indigenous perspectives regarding sovereignty provide a counter-point to the dominant legal discourse and weave an alternate narrative that challenges the myth of objectivity and neutrality that surrounds the doctrine of sovereignty and international law generally. Once we recognize that sovereignty is a social construct, we can recognize our collective ability to reconstruct international laws in a manner that transcends the sovereign discourse and recognizes the rights of Indigenous peoples. Endorsement of the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) is indicative of states’ commitment to recognize Indigenous peoples’ rights throughout the international legal system. This thesis concludes by offering a proposal for reconstructing transboundary water law through a return to ethics and coalition building. Future reform should be directed towards (a) articulating an international water ethic with the critical engagement of Indigenous peoples; and (b) ensuring that river basin organizations are established on every transboundary river in a manner consistent with this shared international water ethic.Law, Faculty ofGraduat

Reconstruction of interactions in the ProtoDUNE-SP detector with Pandora

International audienceThe Pandora Software Development Kit and algorithm libraries provide pattern-recognition logic essential to the reconstruction of particle interactions in liquid argon time projection chamber detectors. Pandora is the primary event reconstruction software used at ProtoDUNE-SP, a prototype for the Deep Underground Neutrino Experiment far detector. ProtoDUNE-SP, located at CERN, is exposed to a charged-particle test beam. This paper gives an overview of the Pandora reconstruction algorithms and how they have been tailored for use at ProtoDUNE-SP. In complex events with numerous cosmic-ray and beam background particles, the simulated reconstruction and identification efficiency for triggered test-beam particles is above 80% for the majority of particle type and beam momentum combinations. Specifically, simulated 1 GeV/$c$ charged pions and protons are correctly reconstructed and identified with efficiencies of 86.1$\pm0.6$% and 84.1$\pm0.6$%, respectively. The efficiencies measured for test-beam data are shown to be within 5% of those predicted by the simulation
