This article examines how the practice of learning geography, and the arenas in which knowledge-making takes place, can be usefully positioned within changing histories of the discipline. It contends that networks of action – understood through the intersection of social sites, subjects and sources – present a conceptual framework and narrative focus for the re-consideration of specific episodes from geography's past. The interventions made here are informed and illustrated by a 'small story' about the doing of geography. Based on different personal accounts, the story revives a series of events, encounters, dialogues and images dating back to the winter of 1951 at Glenmore Lodge, Scotland. This educational institution in the Cairngorm mountains offered children from urban areas the opportunity to learn field studies and the skills of 'outdoor citizenship'. Initially, the focus falls on Margaret Jack, a 14-year-old field-course participant. Her learning experiences are traced through personal letters, a diary and a field journal dating from that time, and her recent recollections of this event. Margaret's account dovetails with the story of her field studies instructor, Robin Murray. Robin's role is traced through his learning experiences as a geography undergraduate at Aberdeen University, and the recent recollections of Catriona Murray, his wife.  相似文献

The Knowledge of Debt: Law, Media Technique, and Everyday Experience in Liberal Capitalism. Performing an object such as ‘the economy’ hinges on practices of formatting knowledge. The article proposes to look at such instituting moments in connection with social conflicts over the legitimate rules of exchange. This is exemplified by way of recounting the story of the codification of Swiss bankruptcy law in 1889. In order to homogenize the legal procedures of debt collection and bankruptcy, two subject categories were instituted: ‘merchants’ and ‘non-merchants’. These different categories were thought to account for the diverging temporalities and spaces of credit exchange in everyday economic life. The introduction of the commercial register, a media-technical apparatus, enabled a formal distinction between ‘merchants’ and ‘non-merchants’. However, this boundary was contested and proved to be porose.  相似文献

Shells of two species of freshwater bivalve (Unio willcocksi Bullen Newton and Etheria elliptica Lamarck) from the predynastic Gerzean (Nagada II) Decorated Tomb at Hierakonpolis, Egypt have given dates of 5000±90 bp for the tomb, and 12,900±120 bp for an episode of Nile terrace accumulation (correlated here with the Sahaba-Darau aggradation event). The archaeological and geological significance of these results is discussed, together with an outline of problems associated with radiocarbon dating of shell. Comparisons are made with the few other radiocarbon dates available for the Predynastic period in Egypt and possible reasons for the presence of shells in the tomb are considered.  相似文献

The later post-glacial history of a valley in the chalk escarpment near Brook, Kent, is described, based on molluscan stratigraphy, archaeological evidence and radio-carbon dating. Differences in size and colour banding, respectively, of fossil and living representatives of two species of land snails, Pomatias elegans (Müller) and Cepaea nemoralis (L.), are correlated with climatic change during the post-glacial period. The problems of the use of fossil shells of these species as samples for radiocarbon dating are discussed.  相似文献

A Singapore-based economic geographer explores and analyzes the spatially uneven evolution of the Internet industry in China, arguing that the country's immense regional disparity in the provision of Internet services is best explained by the interplay of place- and path-dependence. The author demonstrates how the highly uneven regional endowments in relevant industrial and entrepreneurial resources have led to the substantial and persistent regional imbalance within China's emerging "new economy." His initial survey of the country's 100 leading Internet content providers (firms), identified from a listing of ca. 11,700 commercial websites, is selectively augmented to reflect an increase of over 70 million Internet users in 2007, reaching a total of 253 million in June 2008, and thus overtaking the United States as the world's largest Internet market.

This paper discusses the 1911 International Exposition in Rome and illustrates how this patriotic celebration of the fiftieth anniversary of the Italian Sate utilized symbolic landscapes of architecture and archaeology to promote nationalist sentiments of italianità and romanità centered on the young capital of Rome. Through modern art exhibitions at the Valle Giulia, scientific conferences at the Castel Sant’Angelo, archaeological exhibits on the Roman Empire in the Baths of Diocletian, and regional Italian pavilions in the Piazza d’Armi, exposition officials offered a complex representation of Italian national identity that was modern yet ancient, cosmopolitan yet bucolic, European yet regional, and imperial yet developing.  相似文献

Alexander the Great died in 323 B.C. from an unknown cause. By elucidating the nature of his death, we can better interpret various aspects of Alexandrian history. Alexander’s death may have ensued from the sequelae of a congenital scoliotic syndrome. It would therefore be of significance to note that one of the greatest leaders in history who conquered much of the then known world may have been suffering from a physical disability.  相似文献

Lead isotope analyses have been undertaken on a group of Islamic lead‐glazed pottery artefacts from Fustat, Egypt, spanning the period from the eighth to the 14th century ad , that had previously been the subject of a comprehensive typological, chronological, petrographic and technological study. Comparison of the lead isotope ratios for the glazes with those for lead ores from Egypt, Iran, Tunisia, Anatolia, Greece, Sardinia and Spain provided information on the possible sources of the lead used in the production of the glazes. The results show that the lead used in glaze production by the Islamic potters at Fustat was most probably obtained from distant ore sources in Iran or Tunisia, Sardinia, Spain and the Taurus Mountains. Different ore sources were favoured in different periods and, to a limited extent, for different types of pottery, but at no time did the Fustat potters use the potentially more accessible Egyptian ore sources.  相似文献

Schmidt, R., March 2007. Australian Cenozoic Bryozoa, 2: Free-living Cheilostomata of the Eocene St. Vincent Basin, S.A., including Bonellina gen. nov. Alcheringa 31, 67-84. ISSN 0311-5518.

Free-living bryozoans are diverse in the Eocene sediments of the St. Vincent Basin, South Australia. They include Bonellina pentagonalis gen. et sp. nov., Otionellina sp. cf. O. exigua (Tenison Woods), Otionellina sp. cf. O. cupola (Tenison Woods), Tubiporella magna (Tenison Woods), Celleporaria nummularia (Tenison Woods), and an indeterminate species only found as moulds. This diversity and abundance is highest in the sediments representing the initial transgressive marine facies, where they occur in ‘sand fauna’ bryozoan assemblages (e.g. with Melicerita and Siphonicytara). Free-living bryozoans decrease up-section and are absent from latest Eocene sediments, indicating a significant environmental shift.

Der Denkstil der Chemiker. Der Aufsatz diskutiert die Tragfähigkeit des Begriffes “Denkstil”, wie er von Alistair Crombie eingeführt und Ian Hacking aufgegriffen wurde, für das Verständnis dessen, wie das Fach Chemie historisch seine Identität ausgeprägt hat. Obwohl weder Crombie noch Hacking den Begriff “Denkstil” in Bezug auf einzelne Disziplinen verwendet haben, erscheint im Fall der Chemie seine Anwendung besonders vielversprechend, weil er hier hilft, ein zentrales Problem zu thematisieren – nämlich die Frage, wie es Chemikern trotz wechselnder Gegenstandsbereiche und theoretischer Umbrüche gelang, eine eigenständige und stabile Identität auszubilden. Nach einer Einführung in den Begriff “Denkstil”, argumentiert der Aufsatz, dass die Beständigkeit der Chemie als eines Faches wesentlich in ihren Laborpraktiken gründet, die ihrerseits wiederum die spezifische Art der Fragen bestimmten, die Chemiker in ihren Forschungen stellten bzw. die Form der Antworten, nach denen sie suchten. Folgende Merkmale kennzeichnen diesen “chemischen Denkstil” (1) eine spezifische, im Herstellen begründete Form des Wissens, (2) die Befassung mit einzelnen Stoffen und Materialien statt mit Materie im Allgemeinen und (3) eine Beobachtung von Natur besonders im Hinblick auf Transformationsprozesse. The Chemists' Style of Thinking. This paper discusses the relevance of the notion of “styles of scientific thinking” introduced by Alistair Crombie and revisited by Ian Hacking, for understanding how chemistry shaped its identity. Although neither Crombie nor Hacking applied this notion to individual disciplines, it seems appropriate to use it in the case of chemistry because it helps to address a puzzling issue: how did chemists manage to shape an identity of their own, despite shifting territories and theoretical transformations? Following a presentation of the notion of style, I will argue that the stable identity of chemistry is rooted in laboratory practices, which determined the specific questions that chemists put to nature as well as the answers to their questions. The “chemical style of thinking” is characterized by i) a specific way of knowing through making, ii) the concern with individual materials rather than matter in general and iii) a specific commitment to nature.  相似文献

Frequently, in spatial interaction analysis, researchers are forced to use destinations that are zonal aggregates of the ‘real’ destinations perceived by the participants in the interaction process. Previous simulation studies demonstrated that, under certain circumstances, the aggregated spatial choice model can outperform the popular ordinary multinomial logit model, both in explanatory power and predictive ability. In this paper, the two models are compared with interprovincial migration microdata for the time period 1990-91, obtained from the 1991 Canadian census. Since this is not meant to be a migration study, the analysis is limited to out-migrants from Ontario. The results indicate that, at least with the data used, the multinomial logit model performed reasonably well. The paper, however, highlights some practical advantages that can accrue from the use of the aggregated model. Dans l'analyse de l'interaction à référence spatiale, il arrive fréquemment que les chercheurs soient contraints de se servir de destinations qui regroupent les?vraies?destinations perçues par les participants dans le processus d'interaction. Les études en simulations antérieures ont démontré que, dans certaines circonstances, le modèle groupé des choix à référence spatiale peut donner de meilleurs résultats que le modèle ordinaire commun du logit multinomial, sur le plan de la capacité d'explication comma sur celui de la valeur de prévision. Dans la présente étude, on fait la comparaison entre les deux modèles en utilisant les microdonnées sur l'émigration interprovinciale en 1990-91 obtenues par le recensement de 1991. L'analyse ne porte que sur les émigrants de l'Ontario puisqu'elle ne vise pas particulièrement l'étude de l'émigration. D'après les résultats, le modèle employant le logit multinomial fonctionne relativement bien, au moins avec les données utilisées. Toutefois, l'étude souligne certains avantages pratiques pouvant inciter à se servir davantage du modèle groupé.  相似文献

In this work we report a pre‐restoration spectroscopic study by a multi‐technique approach on the green pigment and the binder used in illuminations in a codex of the late 15th century. Our analysis aimed to characterize the badly deteriorated parts of the codex, mainly the green parts, by electron paramagnetic resonance (EPR), X‐ray diffraction (XRD), X‐ray fluorescence (XRF) and infrared spectroscopy (ATR‐IR). We will show that a combined study by EPR and IR spectroscopies on model systems allowed us to refine the general information obtained with the other techniques and to identify the binding media surrounding the chromophore Cu(II) ion.  相似文献

The purpose of this article is (i) to propose the concept of policy analysis as a clinical profession, (ii) to relate to the clinical intellectual processes involved in policy analysis, and (iii) following studies in other clinical disciplines, to infer implications for policy analysis and policy analysis instruction. The article will highlight notions of clinical reasoning and clinical cognitive processes relevant to policy analysis and will address reasoning errors associated with bounded rationality and uncertainty in the clinical analytic process. The article seeks to promote awareness of clinical notions and of their relevance for policy analysis practice and instruction.  相似文献

The ‘Krüppelfürsorge’ during the Weimar Republic. Oscillating between an Own Position and the Adoption of Eugenic Arguments. This article examines the discourse about physical disability led by the German ‘Krüppelfürsor‐ge’. It deals with the exhibition GeSoLei (Gesundheitspflege, soziale Fürsorge and Leibesübungen), which took place in Düsseldorf in 1926. The GeSoLei was one of the most popular platforms of the healthy and aesthetic body in the 1920s. It stood in the context of the German ‘national recovery’ after World War I and collected all types of medical, social and athletic professionals to expose their work to a broader audience. Also representatives of the so called ‘Krüppelfürsorge’ presented themselves and at the same time their perspective on people with physical disabilities on this exhibition. The article points out the ambivalent character of their perspective and shows the mixture of including and excluding people with physical disabilities, which was typical for the view of the ‘Krüppelfürsorge’. It demonstrates that the ‘Krüppelfürsorger’ on the one hand were quite progressive towards people with disabilities, but on the other hand showed a striking openness towards eugenic values.  相似文献

During the ten years covered by this review, the foci of studies in palaeobotany of plant megafossils and certain non-palynological plant microfossils included Precambrian palaeobotany, early vascular plants, Palaeozoic pteridosperms, conifers, and angiosperms. Botanically orientated investigations displayed an increasing use of the electron microscope. Interpretations of palaeoecology and reproductive biology of fossil plants gained increasing momentum. Biostratigraphic studies underwent some new activation but generally took second place to the amount of morphological work. The number of palaeobotanists who completed or received their training during the decade augurs well for the future; there is still much to be done.  相似文献

Previous research has shown that Iznik glazes are characterized by low potash and magnesia contents. It was therefore suggested that the flux used was either a purified plant ash or some unidentified mineral source of soda. More recently, as a result of the detection of small, but significant, amounts of boron and lithium in Byzantine glasses from western Turkey, which also exhibit low potash and magnesia contents, it has been suggested that the source of the flux used was a soda‐rich evaporite associated in some way with the extensive borax deposits in the region. LA–ICP–MS has been used to establish that Iznik glazes also contain similarly small amounts of boron and lithium. The Na/K, Na/Mg, Na/Ca and Na/B ratios for these Iznik glazes are shown to be comparable to the equivalent ratios calculated from published data for waters from a range of Na–HCO3 type hot springs in western Turkey, with the closest match being to the hot springs around Afyon‐Gazligöl, which is consistent with documentary evidence. It is therefore proposed that the soda‐rich salts produced by evaporating water from these springs to dryness would have provided the flux required for the production of Iznik glazes and high‐boron Byzantine glasses.  相似文献
