The fear of population decline in France is deep-rooted and complex. With a renewed decline in fertility in the 1970s, fresh concern has shown itself in the multiplication of books and comments, fitting into a pronatalist tradition which can be traced back at least one hundred and fifty years. In reviewing these works, and other new works on the history of population ideas in France, this paper emphasizes both the uniqueness of the French demographic case and the continuity of reactions both official and private. It isolates key periods of concern in the years before the First World War, in the 1930s and the late 1970s. It also draws attention to the proliferation of propaganda, four examples of which are re-published here. 相似文献

ABSTRACTThe introduction of railway transportation in Great Britain in the early-nineteenth century saw an increased frequency of trauma cases involving persisting symptoms without objective evidence of injury. In 1866, a prominent surgeon, Sir John Eric Erichsen, attributed such symptoms to concussion of the spine (popularized as “railway spine”) that involved an organic pathology, inflammation of the spinal cord in the absence of spinal fracture, with potential psychological overlay. This was widely accepted within the medico-legal context throughout the 1870s, whereby passengers sought compensation for collision-related injuries. In 1883, a railway surgeon named Herbert William Page countered the assertion that many of Erichsen’s cases likely had sustained direct physical injury to the spine, the cord, and/or the spinal nerves; and in cases without such injury, the symptoms were psychogenic, as in traumatic neurasthenia and/or hysteria. Similarities between Erichsen’s and Page’s medico-legal positions, such as conscious and unconscious forms of symptom exaggeration that would both resolve upon settlement of the case, ushered in the era of medical injury compensation. 相似文献

A group of six radiocarbon dates for human skeletons found at the Iron Age hillfort of Danebury are suggestive of a major killing event. We consider here how the dates, mitigated by a careful consideration of the archaeological evidence for context, can be used in constructing site history. 相似文献
