L’auteur s’est proposé d’étudier dans ce livre « la religion la plus primitive et la plus simple qui soit actuellement connue, d’en faire l’analyse, d’en tenter l’explication »[]. M. Durkheim a entrepris, nous dit-il, cette étude parce qu’elle lui a paru plus apte que toute autre à faire comprendre la nature religieuse de l’humanité. Les religions primitives comportent en effet un minimum de variations. Le groupe réalise une uniformité intellectuelle rare dans les sociétés plus avancées. En p..

De la tombe au territoire : les pratiques funéraires en Normandie durant l’âge du Bronze ancien et moyen

La Normandie a fait l’objet, depuis une vingtaine d’années, de nombreux programmes de recherche centrés sur l’âge du Bronze (entre 2300 et 800 avant notre ère) et abordant les notions de chronologie, d’habitat et d’emprise territoriale. Dans ces travaux résolument multiscalaires, la variable funéraire, sans être minorée, n’a jamais fait l’objet d’un travail complet et ce, malgré un fort potentiel. Les contextes funéraires de l’âge du Bronze mis au jour en Normandie se sont en effet multiplié..

Swim-Training Changes the Spatio-Temporal Dynamics of Skeletogenesis in Zebrafish Larvae (Danio rerio)

Fish larvae experience many environmental challenges during development such as variation in water velocity, food availability and predation. The rapid development of structures involved in feeding, respiration and swimming increases the chance of survival. It has been hypothesized that mechanical loading induced by muscle forces plays a role in prioritizing the development of these structures. Mechanical loading by muscle forces has been shown to affect larval and embryonic bone development in vertebrates, but these investigations were limited to the appendicular skeleton. To explore the role of mechanical load during chondrogenesis and osteogenesis of the cranial, axial and appendicular skeleton, we subjected zebrafish larvae to swim-training, which increases physical exercise levels and presumably also mechanical loads, from 5 until 14 days post fertilization. Here we show that an increased swimming activity accelerated growth, chondrogenesis and osteogenesis during larval development in zebrafish. Interestingly, swim-training accelerated both perichondral and intramembranous ossification. Furthermore, swim-training prioritized the formation of cartilage and bone structures in the head and tail region as well as the formation of elements in the anal and dorsal fins. This suggests that an increased swimming activity prioritized the development of structures which play an important role in swimming and thereby increasing the chance of survival in an environment where water velocity increases. Our study is the first to show that already during early zebrafish larval development, skeletal tissue in the cranial, axial and appendicular skeleton is competent to respond to swim-training due to increased water velocities. It demonstrates that changes in water flow conditions can result into significant spatio-temporal changes in skeletogenesis

A global corporate census: publicly traded and close companies in 1910

In 1910 the world had almost half a million corporations, only one-hundredth of today's total. About one-fifth—with over half of corporate capital—were publicly tradable, higher portions than today. Most publicly quoted corporations traded in Europe and the British Empire, but most close (private) corporations operated in the US, which, until the 1940s, had more corporations per capita than anywhere else. The 83 countries surveyed here differed markedly in company numbers, corporate capital/GDP ratios, and average corporate size. Enclave economies—dominated by quoted (and often foreign-owned) companies—had the largest average sizes, while other nations had more varied mixes of large quoted corporations and close company small and medium enterprises
