The emergence of neurology as a separate specialty from internal medicine and psychiatry took several decades, starting at the end of the nineteenth century. This can be adequately reconstructed by focusing on the establishment of specialized journals, societies, university chairs, the invention and application of specific instruments, medical practices, and certainly also the publication of pivotal textbooks in the field. Particularly around 1900, the German-speaking countries played an integral role in this process. In this article, one aspect is extensively explored, notably the publication (in the twentieth century) of three comprehensive and influential multivolume and multiauthor handbooks entirely devoted to neurology. All available volumes of Max Lewandowsky's Handbuch der Neurologie (1910–1914) and the Handbuch der Neurologie (1935–1937) of Oswald Bumke and Otfrid Foerster were analyzed. The handbooks were then compared with Pierre Vinken's and George Bruyn's Handbook of Clinical Neurology (1968–2002).

Over the span of nearly a century these publications became ever more comprehensive and developed into a global, encompassing project as is reflected in the increasing number of foreign authors. Whereas the first two handbooks were published mainly in German, “Vinken & Bruyn” was eventually published entirely in English, indicating the general changes in the scientific language of neurology after World War II. Distinctions include the uniformity of the series, manner of editorial involvement, thematic comprehensiveness, inclusion of volume editors in “Vinken & Bruyn,” and the provision of index volumes. The increasing use of authorities in various neurological subspecialties is an important factor by which these handbooks contrast with many compact neurological textbooks that were available at the time.

For historiographical purposes, the three neurological handbooks considered here were important sources for the general study of the history of medicine and science and the history of neurology in particular. Moreover, they served as important catalyzers of the emergence of neurology as a new clinical specialty during the first decades of the twentieth century.  相似文献

This article investigates a commonly held critical conception of Leopold Bloom by questioning where his cognitive processes are situated. It argues that throughout Joyce's “Hades” episode, Bloom's mind seeps out into the storyworld, offloading onto his material setting. Bloom reflects on his dilemmas using different cognitive markers throughout his environment. As representational cues, they allow him to process his insecurities about his paternal and conjugal roles. A cognitive frame reveals how Bloom's kind acts often originate from his personal and familial preoccupations rather than what has been previously represented as genuine human sympathies. It shows Bloom as even more purposefully strategic than the Homeric parallels identified by most critics have traditionally conceived. Not only do we gain a greater depth of understanding about Bloom's character through an analysis of the situated mind; we also see thematic threads unfolding through objects and characters in ways previous scholarship has not seen. These thematic threads constitute substrata that further disclose the complexity and depth not only to Bloom's character but also Ulysses as a whole.  相似文献

In a recent two‐part article on the nature of kinship, Marshall Sahlins maintains that performative criteria for kin‐reckoning are at least as salient as procreative ones, and that, at conception, an individual is endowed with a wide circle of kin, including the ancestral dead. For both reasons, he argues, there is no warrant for granting privileged status to what anthropologists have called ‘primary’ kinship. The contentions here are that performative criteria are modeled upon procreative ones; that ties to ancestral figures are seen as antithetical to procreative ties; and that, therefore, all kinship constructs are derived from nuclear family relationships. Evidence in support of these contentions is provided from the Mae Enga, Fiji, the Trobriands, and Aboriginal Australia.  相似文献

Heterogeneous quartzite artefact finds from North America's Late Paleoindian period occur in several areas throughout the Northern Great Lakes region. Standard petrographic analysis, back-scatter scanning electron microscopy and cathodoluminescence are used to identify the properties of a regionally abundant, high-quality orthoquartzite stone as compared with high-quality Hixton silicified sandstone from the Silver Mound Archeological District in Jackson, Wisconsin. The results demonstrate the potential for reducing misidentification among material sources, and also exhibit the acutely discerning tendencies of pre-contact peoples. Lithological interpretations of thin sections identify the different properties of the Hixton material. Conversely, Mesnard quartzite, while it functions adequately as a tool stone, is fundamentally compromised of a tightly packed microstructure. This microstructure produces a hard, less tractable material with erratic breakage, possibly explaining Mesnard quartzite's limited distribution prehistorically.  相似文献

渭河流域的大地湾文化诞生了迄今为止我国最早的一批彩陶,彩陶的制作不但反映了当时人们认识自然、利用自然的程度,也反映了大地湾先民的精神世界。为了了解大地湾先民对彩陶白色颜料的认识情况,采用扫描电子显微镜(SEM-EDS)、X射线衍射(XRD)、拉曼光谱(Raman)、红外光谱(RTIR)、热分析(TG-DSC)方法,分析了大地湾遗址出土4块白(浅)色块状颜料的化学组成、物相组成、热性能。结果发现,白色块状颜料主要分为两类:一类是碳酸盐类,QD1(大地湾二期)和QD2(大地湾四期)主要含有石英、白云石、白云母、绿泥石等;另一类是铝硅酸盐黏土矿类,其中,QD3(大地湾四期)白色部分主要含有石英、无定型的高铝硅酸盐(可能为偏高岭石和钾长石)、方石英、莫来石、钛铁矿等,红色部分为赤铁矿小颗粒,样品表面有碳酸钙沉积,而QD4(具体分期不详)主要含有石英、白云母、钠长石、高岭石等,样品表面有碳酸钙沉积。研究结果可为探讨大地湾先民对彩陶颜料原料的处理、加工情况,制陶工艺水平提供数据支撑。  相似文献

Through qualitative comparative analysis of policy documents and official statements over the last 10 years (2008–2018), this paper examines Australian and PRC government conceptions of the international order and the associated policy implications. Their understandings of the international order are informed by their self-defined national role conceptions and perceptions of other states, and are manifested in discussions of institutional reform, international law and human rights. Australia's self-conception as a middle power informs its emphasis on maintenance and US leadership of the existing order, while the PRC's self-conceptions as both a developing and established power enable it to frame itself as either an upholder or reformer of the order. Both governments highlight the ‘rules-based’ mechanisms of the WTO, and are more likely to agree on trade and economic issues than on other matters. Their responses to the 2016 South China Sea arbitration tribunal decision and discussions of the role of human rights in the international order suggest less agreement is likely on international law and human rights norms. While Australia considers the PRC a potential challenger to the existing order, Australia does not feature in PRC discussions of international order, suggesting its limited ability to affect PRC foreign policy decisions.  相似文献

Much has been said about what philosophy of history should be. This bibliometric assessment of research in the philosophy of history examines what scholars in this field have actually produced. The study covers a dataset—a subsection of the bibliography of the International Network for Theory of History—of 13,953 books, articles, book chapters, dissertations, and other scholarly publications, encompassing materials written in seven different languages published between 1945 and 2014. This material was classified according to a multilayered system of taxonomy consisting of keywords representative of themes discussed in the field. Separate quantitative analyses were made to elucidate characteristics about the publication outputs in the field in the different language groups. Changes in paradigm, often referred to as “turns” or “trends,” have been mapped in this study, according to a quantitative analysis of the most recurrent keywords within a five‐year interval, which give an indication of the most debated themes in each period. ?Religion/theology/secularization? is the most frequent keyword during the period 1945 to 1969, followed by ?Marxism/historical‐materialism?1 from 1970 to 1984, in what can be considered a second period of the field. Although many of the key publications of the linguistic turn were written within this second period, our dataset shows that it is not until the third period (1985–2014) that their writing goes on to influence other authors in the field.  相似文献

This paper investigates the dynamics of school quality capitalization during the boom–bust cycle of the housing market. We find that the housing downturn led to a sharp increase in capitalization for high‐quality schools, whereas the boom and recovery periods saw a decline in valuation for top schools. Hence, the capitalization of school quality exhibits a strong countercyclical trend with the overall housing market. We test whether our findings are driven by households “trading down” from private schools during downturns or the fact that the housing supply responds asymmetrically during the boom and bust, but we find little support for these propositions.  相似文献
