Despite there being several estimates for famine-related deaths in the west of The Netherlands during the last stage of World War II, no such information exists for war-related excess mortality among the civilian population from other areas of the country. Previously unavailable data files from Statistics Netherlands allow researchers to estimate the number of war-related excess deaths during the last stage of the war in the whole country. This study uses a seasonal-adjusted mortality model combined with a difference-in-difference approach to estimate the number of excess deaths in the period between January 1944 and July 1945 at a total of close to 91,000 (75%) excess deaths. Almost half of all war-related excess mortality during the last year of the war occurred outside the west.  相似文献

This article addresses the Maltese traditional family, taking St. Mary's (Qrendi) as a test case. It results that couples married in their early twenties, while a high proportion of men and women never married at all. Marriage was not popular so that one-fifth of all marriages were remarriages. Very few widows remarried and it was only for some economic reason that they sought another man. There is no evidence though that a high rate of celibacy resulted in flagrant promiscuity even if there is evidence that the Qrendin were not so particular about their sex life. No birth control was practiced within marriage and children followed one another regularly. This brings into relief the parents' unconcern for their offspring's future as well as the inferior status of women because husbands made their wives several offspring. Relations between the spouses were poor so that dissatisfied couples went their own ways.  相似文献

Researchers are increasingly aware that nonlinear perspectives of the transition into adulthood and non-economic motives, such as family and friends, may help to improve our understanding of young adults' migration decisions. This paper combines these new insights with the traditional economic success–failure arguments in order to explain young adults' return migration to their rural home region. We present four orientations in return motives: the social, family, functional and partner orientation. They consist of different combinations of the stereotypical success–failure arguments with non-serial transitional stages, and with different attachments to the home region. They also show that in some cases, return migration should actually be interpreted as staying in the home region, because the young adult returnees had not mentally left the region. We therefore state that our results provide a solid argument for reinterpreting the out-migration of young people from rural areas.  相似文献

The notion of heredity of degenerative constitutions of human beings contributed in the nineteenth century to the fear for deterioration of the human race and in the twentieth century to attempts by several Western Countries, particularly Germany, to improve the inborn qualities of their populations by eugenic measures. In the years following World War II, the term eugenics was eradicated from medicine. The qualification degenerative disappeared from genetics and psychiatry but remained in use to denote decay of tissues and cells. The adjective neurodegenerative came in vogue in neurology and was mostly applied to brain diseases. Definitions in the literature indicate that neurodegenerative diseases are considered as to be age related, incurable, and largely untreatable chronic progressive diseases of the central nervous system. Scrutiny of available data shows that the notion concerns an ill-defined group of genetic and idiopathic disorders. Genetic central nervous system diseases may become manifest at all ages and are accessible for symptomatic treatment. Investigations of animal models suggest that not all neurodegenerative diseases are inherently incurable. Alternatives for the terms neurodegenerative and degenerative are available.  相似文献
