Le génocide des Arméniens et l'opinion publique française durant la Première Guerre Mondiale

Durant la Première Guerre Mondiale, la presse parisienne de l'arrière évoque abondamment le génocide des Arméniens, tant pour dénoncer les massacres que pour alimenter un discours propagandiste visant à la mobilisation de guerre de la société civile. Les journaux voient en l'Allemagne l'instigatrice du génocide, plaçant la souffrance arménienne dans la continuité des exactions commises à l'encontre des Belges. Certains journaux parisiens se servent également du génocide des Arméniens pour opposer musulmans et chrétiens dans un discours aux accents de guerre de religion tandis que la presse de droite fait occasionnellement preuve de xénophobie à l'encontre des réfugiés et des victimes. La situation s'inverse même à la fin du conflit; le génocide des Arméniens étant dénoncé comme « bourrage de crâne » dans le but de promouvoir le rapprochement Franco-Turc.     

What can supraspecies richness tell us?

Biogeographers, ecologists, palaeontologists, and conservation managers often deal with checklists in which not all individuals have been identified to a species level, or the accuracy of species identification is questionable. Is it possible and credible to investigate species richness based on such checklists? Studies on macrofauna in the Far Eastern seas, eastern Arctic seas, and adjacent waters of the Pacific and Arctic Oceans suggest that in different habitats and for diverse taxa, species, and higher taxa richness strongly correlate with each other and increase with an expansion in the study area and sample size according to the species–area law. Such an increase is higher in the bottom zone than in the pelagic. Species and higher taxa richness also show a decrease from lower to higher latitudes, which is in line with the Humboldt–Wallace’s law. According to Willis’ law and self-similarity in the organisation of taxonomic levels, species richness can be assessed based on the genus, family, and order richness. In other words, supraspecies richness itself can tell us the same as species richness and therefore certain global patterns revealed at the species level may also be revealed at the supraspecies level. Such a concordance in general trends among richness parameters at different taxonomic levels in practice implies that species richness can be studied based on lists that lack species identifications or lists with doubtful species identification. We suggest bolder use of supraspecies richness in science and practice, discussing the disadvantages and advantages of this approach.     

Leçons Privées

While numerous signs and traces remain from the public lectures given during the early modern era in German universities, mentions of the private lessons held by the teachers at their homes are seldom found. This study intends to appraise the importance of these private lectures both for teachers and students as well as for the functioning of the universities. In addition, a close look at these lessons appears to enable us to understand how the seminar form was born and how it became rooted in German universities during the 19^th century.     

What do aqueous geothermometers really tell us?

The application of chemical geothermometry to shallow groundwaters or spring discharge assumes that there is minimal mixing or re-equilibration of water as it travels from depth to the surface. In this study, we examine the potential for mixing and re-equilibration by examining heat and fluid flow along crustal-scale faults in tectonic geothermal systems. Numerical modeling results indicate that maximum in situ temperatures could be under-predicted by up to 30% due to mixing of fluids that enter the fault at different depths. This, coupled with the depression of isotherms by downward groundwater flow in the hanging wall, could cause underestimates of maximum circulation depth of greater than 80% in extreme cases. Kinetics does not favor re-equilibration in the shallower portions of faults due to low temperatures and higher fluid velocities. However, in areas of deeper circulation or higher heat flow such reactions are possible.     

Should we allow terrorists to terrify us?

These two books focus not on terrorism as such, but on its psychological impact on society. Stuart Croft traces the formation of American public opinion on terrorism in the aftermath of 9/11. He argues that public opinion might have followed a different course, but stresses that attitudes to terrorism were formed not just by government or the media, but were linked to other forces such as fundamentalist religion and were even reflected in works of fiction. John Mueller asks which is the greater threat: terrorism or our reaction to it? He cites numerous cases in the past where Americans overreacted to perceived dangers; and points out that terrorism causes far fewer deaths than, for example, road accidents. He ends by suggesting that the best way to disarm terrorists is to persuade Americans to stop worrying about them—while conceding that this advice is unlikely to be followed. Critics of this book may object that it implicitly underrates the terrorist threat. But this in no way invalidates the message of both these books—namely that a genuine, or genuinely perceived, threat can sometimes lead to a disastrous response. Therefore, reports of alleged threats require more careful scrutiny by both politicians and the media.
