Les Ammonoïdes (Mollusca, Cephalopoda) : avancées et contributions récentes à la paléobiologie évolutive.
2009
12 pages; Les ammonoïdes qui perdurent 335 Ma constituent un modèle de choix dans l'analyse du fait évolutif. Cet article de synthèse se propose d'aborder (1) : leur place phylogénétique au sein des céphalopodes et le choix d'un modèle actuel de référence ; (2) : la construction d'espaces phénotypiques qui offrent un angle d'étude pertinent de l'évolution biologique ; (3) : les concordances et discordances entre reconstruction phylogénétique et registre fossile et (4) : les reconquêtes postcrises, modèles d'étude de l'évolution à grande échelle. Il ressort que les ammonoïdes peuvent servir d'appui à de nombreuses thématiques paléontologiques (dynamique de la biodiversité, analyse phylogénét…
L'apport du sentiment de l'investisseur dans l'explication des crises boursières : Une analyse en données de panel
2011
Un debat tres anime portant sur le lien entre les aspects comportementaux des investisseurs et les marches financiers s’est largement developpe au cours de la derniere decennie.

Intranasal midazolam for treating acute respiratory crises in a woman with stiff person syndrome.
2020
Stiff person syndrome (SPS) is a rare neurologic disorder characterized by progressively worsening rigidity and spasms of the axial and limb muscles. Dyspnea has been recently recognized as a common symptom in SPS,1 and life-threatening respiratory crises have been occasionally reported and suspected to be responsible for sudden death in these patients.2,3 The pathophysiologic mechanisms of these respiratory manifestations remain unclear. Some authors have hypothesized that rigidity and/or spasm of the muscles of the trunk could prevent normal rib cage movements and excursion of the diaphragm.1
Climate fluctuations and trajectories to complexity in the neolithic: towards a theory:
2009
Theories about the emergence and spread of farming in western Eurasia have a long research history. Occasionally, climate fluctuations have served as explanations for short-term culture change. However, the entire Holocene climate fluctuation sequence has so far not been regarded. First steps towards a theory which combines the successive stages in Neolithization and early to Mid-Holocene climate fluctuations are described.
The Consequences of Banking Crises for Public Debt
2010
The aim of this paper is to assess the consequences of banking crises for public debt. Using an unbalanced panel of 154 countries from 1980 to 2006, the paper shows that banking crises are associated with a significant and long-lasting increase in government debt. The effect is a function of the severity of the crisis. In particular, for severe crises, comparable to the most recent one in terms of output losses, banking crises are followed by a medium-term increase of about 37 percentage points in the government gross debt-to-GDP ratio. Measuring the increase in debt in this manner seems more appropriate than some of the measures used in the literature that have provided off-quoted and very…

Contingent convertible bonds for sovereign debt risk management
2015
We consider convertible bonds that contractually stipulate payment standstill, contingent on a market indicator of a sovereign's creditworthiness breaching a distress threshold. This financial innovation limits ex-ante the likelihood of debt crises and imposes ex-post risk sharing between creditors and the debtor. Drawing from literature on contingent contracts, neglected risks, and bank CoCo, we extend prevailing arguments in favor of sovereign CoCo (S-CoCo). We discuss issues relating to their design: which market trigger, market discipline and sovereign incentives, and errors of false alarms or missed crises, and provide supporting evidence with eurozone data and a simple simulation on t…
