Although resection of cervical “chondromas” had been reported since the late twenties, the true nature of this condition was not recognized at that time. This paper reports a case of “inferior cervical radiculitis by herniation of nucleus pulposus” operated by Prof. Angelo Chiasserini Sr, one of the founders of Italian neurosurgery, in January 1937. To our knowledge this represents one of the first examples of correct etiopathogenetic interpretation of cervical disc disease. Surgery was followed by excellent recovery, a quite remarkable result in those times. The case history is reported in detail, and a short historical sketch of cervical disc disease is depicted. 相似文献

This paper presents the results of strontium (Sr) isotope analysis of modern and archaeological animal remains and modern plant samples from the Caribbean region. The goal is to assess if patterns of human mobility can be determined from the archaeological record in an archipelagic setting. The range of variability and spatial distribution of biologically available strontium isotope signatures is reported and data evaluated to determine if sufficient heterogeneity exists to permit the identification of mobility despite the presence of potentially large contributions of marine strontium in island and coastal ecosystems. The (is)landscape is divided into several sub-regions based on the age and lithology of underlying geology and the variability of 87Sr/86Sr ratios is reported as; mean 87Sr/86Sr ± 2 standard deviations, number of samples: 1) Volcanic and Intrusive rocks (0.7077 ± 0.0019; n = 162); 2) Cretaceous–Miocene Limestone (0.7085 ± 0.0009; n = 50); 3) Pliocene–Quaternary Limestone (0.7091 ± 0.0004; n = 54); 4) Sedimentary Deposits (0.7094 ± 0.0015; n = 16); 5) Metamorphic Deposits (0.7104 ± 0.0014; n = 6). There are substantial differences between expected 87Sr/86Sr values based on associated geology and measured 87Sr/86Sr in flora and fauna samples. These differences emphasize the importance of focusing on bioavailable strontium, as opposed to geological proxies, for estimations of Sr isotope ranges, especially in archipelagic environments. While some overlap exists between the 87Sr/86Sr ranges of certain sub-regions, other sub-regions possessed limited variation and could be distinguished based on strontium isotope data. This spatial patterning of biologically available strontium indicates that strontium isotope analyses can be successfully applied to the archaeological study of human mobility within the Caribbean region. 相似文献

This article examines the causes and subsequent cover-up of the massacre of Algerians by French security forces on 17 October 1961, and assesses the place and symbolic importance the memory of this massacre has come to occupy within Algerian immigrant communities and antiracist groups since the 1970s. These groups have actively campaigned for official recognition of the extent of and responsibility for the massacre. Finally, the article reflects on the way in which the 17 October massacre is often discussed in relation to Vichy, and the ambivalent conclusions which can be drawn from this in relation to France's coming-to-terms with its colonial past. 相似文献

Seismic performance of historical vaulted adobe constructions: a numerical case study from Yazd,Iran

Past earthquakes have demonstrated that historical vaulted adobe buildings are highly vulnerable to seismic actions. Hence, it is crucial for such building typologies to be evaluated in terms of seismic capacity. To this end, this article deals with the seismic performance of historical vaulted adobe houses from the city of Yazd, Iran as one of the seismically active areas of the world and possessing a very rich adobe heritage. Thus, and based on a detailed geometrical survey, a representative sample of adobe houses from Yazd was studied using a simplified in-plane analysis based on three geometric indexes. Concerning the out-of-plane behavior, a deeper assessment was conducted by performing a numerical study, where the main influential parameters on the seismic behavior of vaulted adobe buildings were considered. The numerical analyses were carried out by adopting the limit analysis theory implemented in the Block2D software. The results obtained indicate the safe in-plane behavior of most of the houses and the safe out-of-plane response of the sample under gravitational loads. However, the sample out-of-plane safety under earthquake-induced loads seems to be a matter of concern. 相似文献

Clinical examination of the reliability and coherence of the evidence concerning modern neurochemical theories of mental disorders has led some scholars to conclude that support for many of these theories is weak. Nevertheless, these theories continue to be widely promoted. One explanation that has been offered for continued adherence to questionable theory is that it stimulates and gives direction to research. The heuristic value of theory is examined in the present paper by tracing the discoveries that followed from an old theory of schizophrenia, which is--by current consensus--false. It is shown that the original serotonin hypothesis of schizophrenia did, in fact, lead to significant advances in neuropharmacology, neurology and psychiatry. 相似文献

I review the taxonomic history of two problematic mosasaur species, Clidastes liodontus and Clidastes moorevillensis. The genus Clidastes is thought to represent an early radiation of a diverse clade known as the Mosasaurinae. However, most phylogenetic analyses recover the genus as paraphyletic with respect to more highly nested mosasaurines such as Mosasaurus, Prognathodon, and Globidens. The fragmentary holotype of Clidastes liodontus was never figured or fully described, and was destroyed in World War II. Over 20 years after destruction of the holotype, relatively complete specimens were referred to Clidastes liodontus based upon a single, variable character. Another taxon, originally designated Clidastes liodontus moorevillensis in a master’s thesis and then elevated to Clidastes moorevillensis in a separate dissertation, has never been formally described and lacks definitive diagnostic characters that differentiate it from the contemporary concept of Clidastes liodontus. Clidastes provides an excellent example of how historical inertia in taxonomic nomenclature can build over decades and skew our interpretations of the diversity, paleobiology, biogeography, and biostratigraphy of a taxon. Clidastes liodontus is a nomen dubium and Clidastes moorevillensis a nomen nudum. I recommend that both names be abandoned. Removal of those names frees us from a burdensome taxonomy and eliminates cognitive biases that hinder objective understanding and exploration of early-diverging mosasaurines, and is a necessary first step toward a taxonomic revision of the lineage(s) involved. 相似文献

Excavation of an early historical (circa 1900) church cemetery in Cochrane, Alberta, Canada, revealed the graves of six individuals. All but one had been previously excavated and the individuals were re‐interred elsewhere. The remaining grave contained a coffin burial of an infant including most of the skeleton, crowns of forming deciduous teeth, scalp and hair. The remains were excavated and historical research was carried out to determine possible families who had used the cemetery. Skeletal and dental age estimates pointed to a particular individual described in historical records. This identification was confirmed through more precise ageing by dental microstructure, sex determination using DNA, and finally, maternal relatedness by comparison of mtDNA with a living female relative. In addition to describing the analytical methods used, this paper demonstrates the importance of accurately identifying historical burials, particularly when living relatives remain in the community.

Botanical assemblage including charred and mineralized macro plant remains were examined from tell Kedesh in the Upper Galilee, Israel. Flotation samples were collected from various contexts within and outside a large Persian-Hellenistic administrative building complex at tell Kedesh, dated to the 5th to the 2nd century BC, based on the archaeological material. Four AMS radiocarbon dates were obtained on plant macro remains recovered from the flotation samples from the complex. The radiocarbon dates range from the 9th century BC to 17th century AD. The discrepancy among the radiocarbon dates obtained from plant remains and those based on archaeological material can be attributed to bioturbation, including the deep burrowing of harvester ants. The study demonstrates the need for direct radiocarbon dating of the charred plant remains generally assumed to be of ancient origin. This research improves the understanding of depositional and postdepositional processes of plant macro remains and explains their mode of arrival, relevant for the sites with a long occupational history by humans and animals. 相似文献

Burt Green Wilder (1841–1925) was a pioneering naturalist and anatomist who is historically known for his brain collection and for his contributions to neuroanatomical nomenclature. During his 42-year career, Wilder also used brain measurements for education and outreach, especially in regard to issues of race and gender. Additionally, Wilder influenced neuroscience education and acted as a scientific liaison to the public. For example, he designed early implementations of the sheep brain dissections that are still being conducted today, as well as likely conducted the first “Brain Day.” This article reviews each of these topics, as well as others, with the aim of accurately placing Wilder in the history of neuroscience as a naturalist and anatomist who, among other achievements, pioneered the use of brain measurements for education and outreach. 相似文献

Strontium isotope ratio (87Sr/86Sr) analysis of archaeological human skeletal remains is an efficient method of investigating past population movement and residential mobility by determining probable geographical origins for the individuals examined. For this to be achieved, however, a map of biologically available 87Sr/86Sr signatures across the region investigated is needed. This paper presents a first such map for the Aegean, based on 87Sr/86Sr values recovered mainly from archaeological animal dental enamel and modern snail shells from sites largely distributed in the southern part of this region. Although not exhaustive, this comprehensive dataset of local biologically available 87Sr/86Sr signatures shows a marked difference between Mainland sites of the Pindos and Parnassos zones and the islands of south-eastern Aegean crossed by the Sub-Pelagonian zone (0.70808–0.70869), and sites in the central Cyclades and the north-eastern Aegean islands falling into the Attic-Cycladic metamorphic belt and the Vardar zone, respectively (0.70926–0.71187). Biologically available 87Sr/86Sr values from sites on central Euboea in the Pelagonian zone, south-eastern Attica and the western Cyclades in the Attic-Cycladic metamorphic belt, and on Crete in the Gavrovo zone are also relatively high (0.70853–0.70931), but lower than those recorded for the central Cyclades and the north-eastern Aegean. 相似文献

It is essential to combine genealogical and collective biographical approaches with network analysis if one wants to take full advantage of the evidence provided by (hereditary) personal names in historical and linguistic onomastic research. The naming practices of rural families and clans from the 18th to the 20th century can bring us much fresh information about their enduring attitudes and values, as well as about other mentalities of everyday life. Personal names were cultural symbols that contained socially shared meanings. With the help of genealogical method it is possible to obtain a more nuanced understanding of these past naming practices, for example by comparing the conventions of different communities. A long-term and systematic empirical research also enables us to dispute certain earlier assumptions that have been taken for granted in historical onomastics. Therefore, the genealogical method is crucial in studying the criteria for the choices of personal names in the past. 相似文献

One of the main challenges affecting the archaeological study of alluvial landscapes is the intensity of change these environments experience over time. Quick and dramatic alterations in geomorphological dynamics and land exploitation determine the visibility and conservation of the archaeological record. This study proposes an approach to the problem of studying these evolving environments based on the analysis and treatment of a series aerial photographs taken between the 1950s and the present day. This paper is particularly interested in looking at the process of photogrammetric restitution and in validating and comparing the digital terrain models and orthoimages produced. The quantitative analysis and visual interpretation of these results can provide valuable information about the transformation of landscapes and factors affecting surface evidence. The intended final result is to develop the ability to map the most problematic or best preserved areas. Nevertheless, it is considered in terms of a relative measure of change magnitude, rather than trying to provide absolute figures. 相似文献

This is a study of the cults of two holy deacons at Rome: St Stephen and St Laurence. It is argued that the narratives associated with these saints were a medium for the resolution of two key, overlapping areas of tension: status anxiety within the clerical hierarchy, and relations between clergy and wealthy lay patrons. Controlling the ambitions of lesser clergy on the one hand, and on the other commanding the attention of major donors, absorbed a great deal of the energies of Roman priests and their bishop in this period. These issues converged on the figure of the deacon, understood in its early Christian sense as the helper/patron of the bishop. Defining the role of ‘deacons’ through the medium of saint cult was a necessary condition of the institutional development of the Roman church, and of church property. 相似文献

This paper investigates a greenfield mining project in a peripheral region in northern Sweden through the analysis of how different actor groups formed their own ‘horizons of expectations’ that temporally became fused, only to crumble together with the mining company in a short period of time. By focusing on the co-evolvement of expectations, we show how expectations are differentiated along geographical and temporal scales, reflect upon how these differences relate to interests and historical memory, and finally what these differences mean for the development of large-scale, long-term, raw materials-based projects devoted to industrial production in depopulating areas in an economy otherwise orientated towards neoliberal governance and post-industrial development. By doing so, we make a theoretical contribution to the literature on expectations through the introduction of the concept ‘horizon of expectations’, and a contribution to the literature on neoliberalism and its cultural-geographical implications. 相似文献
