This article presents a method for investigating the spatial distribution of vehicle and pedestrian traffic crashes relative to the volume of vehicle and pedestrian movement in urban areas. This method consists of two phases. First, vehicle and pedestrian traffic volumes on the street network are modeled using a space syntax configurational analysis of the network, land use data, and observed traffic data. Second, crash prediction models are fitted to the traffic crash data, using negative binomial regression models and based on traffic volume estimates and street segment lengths. The method was applied in two areas in Tel Aviv, Israel, which differ in their morphological and traffic characteristics. The case‐studies illustrated the method's capability in identifying hazardous locations on the network and examining relative crash risks. The analysis shows that an increase in vehicle or pedestrian traffic volume tends to be associated with a decrease in relative crash risk. Moreover, the spatial patterns of relative crash risks are associated with the design characteristics of urban space: areas characterized by dense street networks encourage more walking, and are generally safer for pedestrians, while those with longer street segments encourage more driving, are less safe for pedestrians, but safer for vehicles. 相似文献
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 domestic architecture in the rural villages of ?zmir comprises a unique built environment with their masonry wall textures, semi-open sofas, round tiled-hipped roofs, and chimneys, and represents an important part of the cultural and architectural heritage. This assessment is mainly based on field observations that focus on the architectural and structural layout of intact, damaged, and destroyed houses. During field observation and the analysis of data certain plan typologies and relationships between the geological formations of the region and choice of materials and construction techniques were observed. While load-bearing masonry and timber skeleton systems are common, extensive use of timber laces, stone, and fired or adobe brick masonry with mud mortar and timber frames infilled with masonry materials were frequently seen. Generally, round timber elements such as wall plates, laces, lintels, posts, and frames of flooring systems are used. Architectural degenerations in authentic houses, defective details and partially due to the earthquake-prone nature of the region seismicity have been evaluated. An overall approach for the preservation and sustainability of this heritage is suggested. 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
