In September 2014, the University of New England (UNE), Australia, began a three‐year programme of archaeological fieldwork and post‐excavation analyses focused on the site of Saruq al‐Hadid. In this paper, we present the initial results of our current field and laboratory research particularly related to site stratigraphy and formation processes, relative and absolute chronology, and the preliminary results of various programmes of post‐excavation analyses including archaeobotanical, zooarchaeological, ceramic and archaeometallurgical studies. These studies provide new data to build into the archaeological understanding of Saruq al‐Hadid that has, to date, focused largely on intensive excavation.  相似文献

The decline in fertility that has taken place in most countries of Asia over the past few decades has presented a challenge to demographic theory. While most families have shrunk considerably in size and the desire for only a few children is shared by most, the importance of producing a male child has persisted in some regions and strata of many Asian societies. The clash between the desire for only a few children and for a male child causes many individuals to experience conflicting reproductive aspirations, particularly women, who are generally held responsible for the sex of their children and whose status depends on their production of male heirs. Based on ethnographic material, I document the different strategies women in rural northern Vietnam use throughout their reproductive years in their quest to have a son. I discuss the construction of reproductive desires with special attention to the need for a son, as such need was the most central element of discourses on reproductive desire in the narratives collected. The article also elaborates on how women maneuver to negotiate these desires between different scales: the local, particularly family, kin and community members; the national, more specifically Vietnam's two-child family planning policy; and the global, with its notions of a good family and of ‘good quality’ children.

Hijos Indispensables: Negociando los deseos reproductivos en Vietnam rural

La disminución de fertilidad que ha ocurrido en la mayor parte de países asiáticos durante las últimas tres décadas ha planteado un desafió a la teoría demográfica. Mientras que la mayoría de familias se ha reducido el tamaño y desean menos hijos, en algunos regiones y estratos de las sociedades asiáticas la importancia de producir un niño masculino ha persistido. El choque entre el deseo de tener menos hijos y un niño masculino resulta en que muchos individuos tengan aspiraciones contradictorias de reproducción, en particular las mujeres quien se responsabilizan generalmente del sexo de sus hijos y también quien depende en la producción de herederos masculinos para su posición social. Haciendo uso de material etnográfica, documento las estrategias distintas que utilizan las mujeres del campo de Vietnam del Norte en sus búsquedas de tener un hijo durante sus años reproductivos. Discuto la construcción de deseos reproductivos, fijándose en la necesidad de un hijo, ya que aquella necesidad era el elemento más central de los discursos de deseos reproductivos en las narraciones recopiladas. Este artículo elabora también en cómo las mujeres manejan negociar estos deseos entre diferentes escalas: la local, especialmente la familia, parientes, y miembros de la comunidad; la nacional, mas específico, la política vietnamesa de dos hijos por familia; y el global, con sus ideas de la familia buena y de niños ‘bien educados’.  相似文献

The major challenge of photography has been freezing movement, to transform it into a fixed image or series of images. Very soon, photographers became interested in movement itself and tried to use photography as a tool to analyze movement. At the early stages, physicians interested in movement, perhaps surprisingly, made important technical contributions. Mécanisme de la physionomie humaine, by Duchenne, the first book with physiological experiments illustrated by photographs, is a landmark in this historical development. At the Salpêtrière, thanks to Charcot, photography officially entered clinical neurology. Medical journals with photographs were actively developed by Bourneville. Londe established a clinical photographic laboratory and published the first book on medical photography. The study of animal and human movement by Muybridge and Marey in the 1880s led to chronophotography and later cinematography. Clinicians such as Dercum and Richer took advantage of these new techniques to study pathological movement and gait in neurological diseases.  相似文献

Scepticism is generally considered as leading to political conformity. But obedience to custom is not the only consequence of the separation between the private and the public spheres. The main result of this separation is to create an area of private life which is a space of freedom, away from the crowd and the authorities. It is thus easier to understand the sceptical stance in politics, advising the Prince secretly, while keeping out of the limelight. Above all, this helps us to appreciate the contribution of scepticism to modern conceptions of liberty in providing a social model for the free pursuit of truth.  相似文献

The distribution of dental caries was determined in complete and partial human dentitions from a 17th century (1621–1640) city graveyard excavated in Gothenburg, Sweden. Sixty‐three adults and two children, divided into five different age groups, were studied. Altogether 949 teeth (943 permanent and six deciduous) were examined macroscopically using a dental probe and X‐rays. A high number of teeth had been lost post‐mortem. An increase in ante‐mortem tooth loss was found with increasing age. Sixty per cent of all individuals and 12% of all teeth showed signs of caries. The number of carious teeth per subject increased with increasing age. The highest prevalence of individuals with caries was found for the age group 26–35 (69%). Caries were most prevalent in the first, second and third lower molars (60%), while the incisors and canines in the upper and lower jaws were the least affected teeth (1%). The occlusal surface was the area most susceptible to caries (45%), followed by the buccal cemento–enamel junction (16%) and the approximal contact point (11%). This study shows that, although consuming a diet believed to have been lower in sugar content compared to modern populations, caries did affect a rather high number of individuals living in Sweden during the early 17th century.
