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

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

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

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

Instrumental neutron activation analysis (INAA) of the bones of a 6th century case (AD ) of hypertrophic osteoarthropathy (HOA) showed high levels of Zn, Mn and K in the periosteal new bone. The concentration of Zn in the periosteal new bone appeared to be biogenetic in origin and connected with active mineralization processes in the abnormal bone tissue. Manganese and potassium concentrations were, at least partly, related to diagenetic processes.  相似文献

ABSTRACT

To assess tourist motivations at the battlefield site on Kinmen Island of Taiwan, an empirical investigation was conducted. From a convenience sample, we collected 437 effective responses of respondents including domestic and international tourists with different cultural background in Kinmen. The structure of motivation was first examined via factor analysis. Then ANOVA analysis was applied to address the influence from demographic aspects such as gender, age, and nationality. Our results show that personal, spiritual, experience, physical, and emotional perspectives are five major sources of motivations. More importantly, age and nationality are confirmed to be two major dimensions to segment tourists in the context of battlefield tourism. Tourists with older age have higher motivations toward the battlefield site in comparison with young tourists. In addition, tourists with different cultural background based on different nationalities are significantly motivated by various motivational factors. The example of Kinmen contributes theoretically to a better understanding of the motivational attributes in a battlefield site, and how they represent a basis for increasing tourist perceptions. The motivational mechanisms and factors explored in this case can be incorporated into marketing strategies. Additionally, our results also provide a viable basis for the tourism authorities concerned to reevaluate the essence of its tourism industry in the context of battlefield resources and attractions.  相似文献

Traumatic dental injuries, although apparently rare in archaeological populations, can be found under certain circumstances affecting the dentition in a variety of ways. This paper contributes to the paleopathology literature by reporting one case of dental trauma. Evidence for differentiating antemortem/perimortem dental trauma from postmortem damage is presented, and it is suggested that these injuries were sustained due to an accidental fall, supported by the morphology, location and extension of the injuries and characterization of the impact. These data provide a valuable information for a reconstruction of past behaviors in the Samnitic necropolis of Opi Val Fondillo (VI-V century BC; Central Italy).  相似文献

This article aims to integrate discourse analysis of politically instrumental imagined identity geographies with the relational and territorial geography of the communities of praxis and interpretation that produce them. My case study is the international community of nationalist scientists who classified Europe's biological races in the 1820s-1940s. I draw on network analysis, relational geography, historical sociology and the historical turn to problematize empirically how spatial patterns of this community's shifting disciplinary and political coalitions, communication networks and power relations emerged, were structured, persisted, changed, interacted and disappeared. I focus especially on core-periphery relations. I argue that if local historical spatial patterns affect those of later phenomena, geographies like that of European integration should be understood in the context of Europe's complex historical cultural geography. Unlike discourse deconstruction alone, this complementary relational de-essentialization of geography can identify large-scale, enduring associations of cultural patterns as well as cultural flux and ambiguity.  相似文献

This paper examines the causes and process of return migration from the coastal region to the inland provinces in China since the early 2010s, based on the case study of Zhumadian city in Henan Province. Surveys administered to both rural migrants from Zhumadian to Shenzhen and recent returnees to Zhumadian are presented. Industrial relocation and the development of inland provinces trigger the current wave of return migration. Family obligations, better prospects of the hometown, and barriers to settle in Shenzhen because of the hukou system are the principal reasons to return. Most of the migrants return to work in a factory or start a business. Some migrants purchase apartments in Zhumadian as a prelude to returning and starting a business at a future date. Returnees prefer settling down in urban areas rather than in their rural origins. In light of the empirical findings, the authors argue that return migration will ease the mismatch of labor supply and demand between the inland and coastal provinces, such that the Lewis Turning Point has not been reached yet. The continuing process of rural migrants returning to and settling down in Zhumadian suggests a way to achieve some of the goals in China’s new-type urbanization plan, as local governments may address the two major challenges of the plan, namely, local job creation and financing for increased demand for public services.  相似文献

Effective Teaching of Research Design in Physical Geography: a case study   总被引:1,自引:0,他引:1  
A problem-solving approach to the teaching of research design in physical geography is introduced. Focusing on the study of the effectiveness of a local river restoration scheme, students are empowered with the responsibility for and control of their learning by means of group discussions and decision making in a series of workshops. With carefully staged guidance by tutors, students devise research questions and execute their project, analysing data collected on a field day. Although students may find this approach to be challenging and demanding, they acquire research experience and develop key skills, such as visualisation of problems and capacity for logical thought, aided by critical self-appraisal of their performance. Such an approach is particularly relevant today because of subject benchmarking skills. Developing transferable skills, such as initiative and teamwork, valued by employers also promotes self-confidence. Using a case study, this paper considers the experiences of students and staff with this approach, identifying its strengths and weaknesses, and offers possible options for its development.  相似文献

儿童或者说童年是每一个成年个体生命最初的“身份”,这已经是我们今天习以为常的认识。然而,在过去半个多世纪的儿童史研究者眼里,儿童(Child)概念却并非如此简单,它被认为是一个由成年人“建构”的文化概念,童年(Childhood)则是一种“结构性”存在,而不是指生理上或年龄上可以与成年人一分为二的自然而然的人生阶段。儿童史研究者正是从与儿童相关的一切历史现象的社会文化史意义出发,将目光转向被历史书写者和史学研究者长期有意或无意忽视的儿童主题。  相似文献
