The Lisbon Treaty: A Brief Outline
The story of the Lisbon Treaty cannot be told--nor can a brief outline thereof be sketched--without going back to the Constitutional Treaty, which represents the background to the Lisbon Treaty and against which the Lisbon Treaty ought to be assessed. That is why the present outline will first refer to the Constitutional Treaty, before addressing the structure and the content of the Lisbon Treaty
Seeking asylum in Europe
This post is the third of four articles to be published as part of this week’s intensive series on refugee and migration rights. Stay tuned for tomorrow’s article on safe passage for asylum seekers in the Aegean Crossing
Can we predict a humanitarian emergency?
Since the end of the Cold War, the humanitarian field has witnessed the emergence of new early warning systems, as well as the improvement of old ones, the purpose being to alert us of imminent humanitarian emergencies. To date, notwithstanding the proliferation of these instruments, their capacity to function effectively within the framework of humanitarianism is questionable. In discussing whether or not early warning systems can be made to function as planned, I argue that their current dysfunction within the humanitarian field is due the existence of a particular emergency imaginary
Epim Policy Update December 2019
This Policy Update’s Special Focus considers the
situation in Greece, where asylum seekers face rapidly
deteriorating reception conditions while being
targeted by toughened asylum laws and plans to
reintroduce systematic detention. Whereas Greece and
the European Commission have urged for greater
returns from Greece to Turkey, other actors are calling
the future of the EU-Turkey Statement into question
Iterated maps for clarinet-like systems
The dynamical equations of clarinet-like systems are known to be reducible to
a non-linear iterated map within reasonable approximations. This leads to time
oscillations that are represented by square signals, analogous to the Raman
regime for string instruments. In this article, we study in more detail the
properties of the corresponding non-linear iterations, with emphasis on the
geometrical constructions that can be used to classify the various solutions
(for instance with or without reed beating) as well as on the periodicity
windows that occur within the chaotic region. In particular, we find a regime
where period tripling occurs and examine the conditions for intermittency. We
also show that, while the direct observation of the iteration function does not
reveal much on the oscillation regime of the instrument, the graph of the high
order iterates directly gives visible information on the oscillation regime
(characterization of the number of period doubligs, chaotic behaviour, etc.)
ICDP Workshop on the Lake Tanganyika Scientific Drilling Project: A Late Miocene–Present Record of Climate, Rifting, and Ecosystem Evolution from the World\u27s Oldest Tropical Lake
The Neogene and Quaternary are characterized by enormous changes in global climate and environments, including global cooling and the establishment of northern high-latitude glaciers. These changes reshaped global ecosystems, including the emergence of tropical dry forests and savannahs that are found in Africa today, which in turn may have influenced the evolution of humans and their ancestors. However, despite decades of research we lack long, continuous, well-resolved records of tropical climate, ecosystem changes, and surface processes necessary to understand their interactions and influences on evolutionary processes. Lake Tanganyika, Africa, contains the most continuous, long continental climate record from the mid-Miocene (∼10 Ma) to the present anywhere in the tropics and has long been recognized as a top-priority site for scientific drilling. The lake is surrounded by the Miombo woodlands, part of the largest dry tropical biome on Earth. Lake Tanganyika also harbors incredibly diverse endemic biota and an entirely unexplored deep microbial biosphere, and it provides textbook examples of rift segmentation, fault behavior, and associated surface processes. To evaluate the interdisciplinary scientific opportunities that an ICDP drilling program at Lake Tanganyika could offer, more than 70 scientists representing 12 countries and a variety of scientific disciplines met in Dar es Salaam, Tanzania, in June 2019. The team developed key research objectives in basin evolution, source-to-sink sedimentology, organismal evolution, geomicrobiology, paleoclimatology, paleolimnology, terrestrial paleoecology, paleoanthropology, and geochronology to be addressed through scientific drilling on Lake Tanganyika. They also identified drilling targets and strategies, logistical challenges, and education and capacity building programs to be carried out through the project. Participants concluded that a drilling program at Lake Tanganyika would produce the first continuous Miocene–present record from the tropics, transforming our understanding of global environmental change, the environmental context of human origins in Africa, and providing a detailed window into the dynamics, tempo and mode of biological diversification and adaptive radiations
Lynx: A knowledge-based AI service platform for content processing, enrichment and analysis for the legal domain
The EU-funded project Lynx focuses on the creation of a knowledge graph for the legal domain (Legal Knowledge Graph, LKG) and its use for the semantic processing, analysis and enrichment of documents from the legal domain. This article describes the use cases covered in the project, the entire developed platform and the semantic analysis services that operate on the documents. © 202
