Archibald Watson was an Australian anatomist and surgeon who kept operating theater diaries. He made detailed notes on the work of surgeons that he observed in Britain and North America, as well as in Australia. Watson's diaries provide significant evidence that early twentieth-century surgeons did not just apply scientific knowledge produced somewhere else. They generated new surgical knowledge themselves and worked within a culture that valued innovation. Some of the surgeons observed by Watson practiced in academic centers and regularly engaged in laboratory research, but most did not. Nevertheless, it is clear that whether in Australia, Britain, or North America, the active search for improved techniques was a routine feature of the practice of full-time surgeons. In the process, they often made mistakes--or rather, they often did things with which at least some of their colleagues did not agree. Much of surgical practice was contestable. Doing things the "right" way and finding better ways to do things were overlapping categories; but it is often difficult or impossible to draw any distinction at all between doing things the "wrong" way and failed attempts at finding a better way to perform an operation. This article examines some aspects of the relationship between scientific ideas, clinical experience, contestable errors, and the generation of new knowledge through surgical practice. 相似文献

Long-term trends in the spatial distribution of the population of Sweden are analyzed in this study. "Two geographical levels, the national and the local, are analysed in a long term perspective, [from] 1750 until 1990. The measure of concentration used is the Hoover-index on [the] county level. Some major determinants affecting population distribution are stressed; demographic components, economic geographic conditions, socio-economic structure, attitudes and population policy. During the last few decades the traditional trend of population has been broken and one finding is that concentration and dispersion is going on simultaneously on the national and the local level." 相似文献

In 1776, the Sienese botanist Biagio Bartalini (1750-1822) published a catalogue of wild plants growing around Siena, adding an appendix on fossils found in the same area, that is the first monograph on Sienese fossils and one of the first works of its kind in Italy. This paper provides tentative identifications of the species and an analysis of the value and meaning of Bartalini's work. The catalogue reports 72 species, each denoted by a list of names applied to analogous living taxa. Identification of single entities is extremely problematical because it can only be attempted through analysis of the literature, since the original material cannot be traced. The most interesting report is the first record of a Euro-Mediterranean Pliocene species of Sthenorytis (Gastropoda, Epitoniidae). Though important, the catalogue is incomplete, with oversights and mistakes, suggesting little familiarity with the subject. Shortcomings include some inconsistencies in the species sequence, the report of giant clams and the absence of molluscs ubiquitous in the Sienese Pliocene and sharks. Nor is it true that it is the first Italian palaeontological work in which binomial nomenclature was used, as sometimes claimed. 相似文献

A systematic sample of the petitions presented to the English Divorce Court from 1858 through 1908 makes it possible to assess the differential contribution of discrete social and economic subgroups to the litigation the Court oversaw. An examination of four of these -- the titled aristocracy, those employed in the theater, those in receipt of financial aid, and laborers -- shows that English divorce litigants exhibited a broader social profile than commonly attributed to it by the newspaper coverage of divorce litigation, which gave a skewed impression of its social profile. Analysis of these cases underscores the gendered, class, and geographically inflected demand for divorce in a judicial setting that imposed severe restrictions on access to divorce as a remedy for marital breakdown. 相似文献

Abandoning a child was no rare deed in European towns in the nineteenth century, mostly among single women in underprivileged environments. On the other hand, taking this same child back was more unusual. By analyzing the registers of the Lyon hospitals, it is possible to determine the percentage of children taken back by their mothers, how this was actually achieved, and to examine the family status of the mothers at the time of both events. Both of these acts -- abandoning a child and then taking it back -- can be put back in their context in these women's lives, for instance, by looking into the length of time separating the two procedures. To finish with, it appears that the 'Hospices civils de Lyon' encouraged mothers to take the children back and generally had a conciliatory attitude toward them, supposedly in the children's interest. 相似文献
