We present the palaeopathological analysis of a right fourth metatarsal (ATD6‐124) recovered from the Atapuerca–Gran Dolina site (Spain). This fossil, ca. 1 Ma, belongs to Homo antecessor, the earliest known European hominin species. The metatarsal exhibits a proliferative lesion on its medial periosteal surface. Periosteal reaction can be the bone response to a wide number of injurious processes. We describe a lesion on the basis of macroscopic and microscopic analyses, including microtomography and scanning electron microscopy. Externally, the osteoblastic lesion presents a highly porotic and disorganised morphology. Internally, we observe a series of micro‐fractures on the compact bone that do not affect the medullary canal. We provide a differential diagnosis and suggest that the ATD6‐124 lesion could correspond to a pedal stress fracture, also known as fatigue or march fracture. Stress fractures have been related to a load increase and muscular fatigue. This type of fracture has been widely reported in the foot of soldiers and athletes, which are usually engaged in strenuous, excessive or prolonged locomotive activities. Despite its high frequency in these groups, stress fractures have not been reported as such in fossil collections, with the exception of a metatarsal belonging to the Sima de los Huesos site (Atapuerca).

Beginning in the early 1950s, a series of epidemiological, biochemical, pathological, and animal studies demonstrated a link between cigarette smoking and lung cancer. A number of reputable scientists challenged these findings, but for a variety of reasons, including the behavior of the tobacco industry, historians have assumed that these objections were insubstantial and disingenuous. Viewing these objections in scientific and medical perspective, however, suggests that there was a legitimate and reasonable scientific controversy over cigarette smoking and lung cancer in the 1950s and early 1960s. That controversy had important consequences. A new chronic disease epidemiology emerged, transforming the role and importance of epidemiology to medical research. This new epidemiology supplemented Koch's postulates, establishing a statistical method that allowed for linking environmental factors to the etiology of chronic diseases. The 1964 report to the surgeon general, Smoking and Health, represented the denouement and codification of these developments. This reexamination of the scientific controversy over smoking in the 1950s and early 1960s provides an important context for understanding the subsequent public relations battles between the tobacco industry and public health after 1964. 相似文献

During the past decade research into the German Final Paleolithic and Mesolithic has experienced an important revival. One clear sign of this renewed interest in the periods are the annual meetings of the Arbeitsgruppe Mesolithikum (Mesolithic Working Group) which have taken place every spring since 1992. At these meetings, which take place at changing venues, topical themes of Final Paleolithic and Mesolithic interest are presented by informal lectures and it is also possible to study regional collections (artifacts, raw materials) at first hand. Numerous contributions were subsequently published together in one volume (Conard and Kind (1998) Aktuelle Forschungen zum Mesolithikum/Current Mesolithic Research, Mo Vince, Tübingen). The present paper intends to complement that collection of papers with a synthesis of developments and perspectives and to present recent research highlights in the German Final Paleolithic and Mesolithic, together with a comprehensive bibliography, to a wider international audience. 相似文献

In medieval miracles of the Virgin Mary that feature images, gazing at Mary and being seen by her can shape or change the identity of the miracle's protagonist. Such miracles often feature figures who have the potential to be adult male Christians but do not yet hold that status; they are transformed by their encounters with the malleable materiality of Marian images. Narratives of a Muslim devoted to a Marian statue and an English child who has to have an image of the Crucifixion explained to him show how questioning the nature of such images, and their material implications, could lead to belief. The widely popular story of “The Jewish Boy” extends the power of the image to suggest that merely looking upon it without understanding is sufficient to create a circuit of likeness and recognition that ultimately leads to conversion. In such miracles, an ostensibly surface-oriented or simplistic mode of religious devotion engages with gendered bodies in powerfully transformative ways that touch on complex theological issues. 相似文献

The article proposes that unfree labour was an integral part of Bronze Age society. The presence of the unfree (thralls or even slaves) in prehistoric societies has rarely been discussed and never in the light of archaeological evidence. The article is based on empirical material from 333 fully excavated house remains from 120 sites in the Viborg area in northwest Jutland, Denmark. Based on the reconstructed size of these longhouses, the location of fireplaces, entrances and the subdivision of space, it is suggested that farmsteads, in general, had two, often clearly separated habitation units. In the Early Bronze Age, a longhouse was usually subdivided into two parts, and during the Late Bronze Age, this subdivision manifested in the construction of two longhouses. After a thorough analysis of the archaeological record, it is suggested that the owner of the land had occupied one habitation unit, while the other was reserved for the unfree. 相似文献

Ungulate footprint-tracks provide information regarding the species and age of animals. Combined with other datasets, this contributes to interpretation of seasonal husbandry patterns in the Severn Estuary, focusing on Bronze Age intertidal footprint-tracks at Redwick and Goldcliff East and the Late Neolithic site of Oldbury. Metric dimensions and morphology of modern contemporary ungulate footprint-tracks are used as analogues to help understand the species and age of prehistoric ungulates. Findings indicate that Dexter cattle and Soay sheep are metrically similar to British prehistoric ungulates. The prehistoric sites have a concentration of neonatal and juvenile individuals. Along with evidence provided by environmental data, faunal skeletal assemblages and lipid and isotopic analysis, this leads to the conclusion that the presence of younger animals and evidence at Brean Down for dairying is consistent with saltmarsh grazing activity in spring and summer. 相似文献

After years in the wilderness, economic history is becoming fashionable once more. Intellectual shifts by its parent disciplines of history and economics, the failed experiment of economic history as a separate discipline, and the impact of major economic events have conspired to produce a renaissance in the field of study in the last decade and a half. We explain these changes and show that economic history derives its main strength from its role as an interdisciplinary research field that draws upon and integrates with its closest disciplines. We analyse the nature and recent progress of economic history in Australia and offer a prospective for its future role. 相似文献
