Evaluating Crash Risk in Urban Areas Based on Vehicle and Pedestrian Modeling

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.     

Matthew Flinders through French Eyes: Nicolas Baudin’s Lessons from Encounter Bay

The encounter between Nicolas Baudin and Matthew Flinders off the south coast of New Holland in April 1802 has attracted considerable attention. For many, it has come to symbolise the triumph of the spirit of international scientific cooperation over national rivalries and personal ambitions. Scholarly analysis of the complexities of the encounter moment itself has, however, served to modify this idealised image. The injustice subsequently done to Flinders by François Péron and Louis de Freycinet, who failed to acknowledge his discoveries on this coast in the published account of the French voyage, has also generated much discussion. The impact of the encounter on Baudin and his men, on the other hand, has not been subjected to the same scrutiny. Through a close examination of the archival documentation, this essay offers the French perspective on Matthew Flinders and highlights the ramifications for the Baudin expedition of this fateful meeting with him.     

From the Parish to the Publich Realm

The parish church held a central place in local communities in the 18th century, both physically and symbolically; however, the institutions and practices governing the churches differed significantly between the Scandinavian countries. This article traces the development of local church government in Norway from its position under 18th-century absolutism to its inclusion into the new system of local self-government, established in 1837. It is compared to the very different institutions of self-government in Sweden in the same period. Although there were many lines of continuity within local government across the political dividing line marked by the Norwegian constitution of 1814, both local church offices and the parish community underwent conceptual changes related to the new constitutional system. Local church government therefore provides an example of how the notion of the population in general changed from absolutism to constitutional rule; from commoners in contradistinction to the state to communities constituting the very foundation of the state.     

Recent archaeological research at Saruq al‐Hadid,Dubai, UAE

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.     

In the lure of Geistesgeschichte: the theme of decline in Hungarian historiography and historical thinking in the first half of the twentieth century

Decline was the fundamental issue in Hungarian historiography and historical thinking between the two world wars. This article primarily analyses the views of historian Gyula Szekf?, the writers and essayists Dezs? Szabó and László Németh, and those of philosophers Lajos Fülep and György Lukács. In this period, the so-called spiritual history (Geistesgeschichte) prevailed in Hungarian intellectual circles, in which the themes of decline and even fall were fundamental. Of the most important representatives of Geistesgeschichte, Spengler, Ortega, Huizinga, Croce and Maritain had significant influence on the authors mentioned above. Historians were ready to reject the ideas of these thinkers regarding the criticism of culture, and rather followed the power- and state-centred streams of Geistesgeschichte, conceived by Ranke, Troeltsch and Meinecke. At the same time it is also true that the decline and generation theory developed by the historian Gyula Szekf? (e.g., in his book Three Generations), is one of the most original interpretations of modern Hungarian history. It was shared by many Hungarian intellectuals of the period. Paradoxically, the theme of decline also appeared in the views of the so-called ‘Századok’ (Centuries) circle, mainly in the writings of the historians István Hajnal and István Szabó. They rather followed the social-history-oriented French Annales School, and even attempted to offer a solution to the problems of the so-called ‘third way’ alternative. Almost all of the above-mentioned concepts were tied in the later political discourse to the so-called right-wing tradition of Hungarian political–historical thinking, but the author also touches briefly upon the notion of decline in the leftist (Marxist) tradition of György Lukács, whose ideas had an impact on the beginnings of the Frankfurt School. The article also offers a brief overview of the main ideas of spiritual history/Geistesgeschichte, since the author suggests that this was a common feature in all the interpretations of decline in the period treated here.     

Application of Particle Motion Technique to Structural Modal Identification of Heritage Buildings

Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).     

In Situ Characterization of Rammed Earth Wall Renders

The Algarve region in southern Portugal has one of the most significant rammed earth construction legacies in the country. This construction method is characterized by its high susceptibility to water damage and external renderings are essential to the longevity of these constructions. This study collects and organizes data that provides the basis for the conservation and repair of renderings. Five earth buildings from western Algarve were selected to represent this heritage and its diversity of composition and susceptibility to water damage. Some of their commonest anomalies result from the interaction between the earth substrate and the traditional external renderings, given their distinct characteristics and behavior. The selected sample is described and the mechanical strength of the rammed earth walls and their renderings are evaluated through in situ tests. Samples of the external renderings and earth substrate of the five buildings comprising the sample were also collected and characterized in the laboratory. The characteristics of these two materials and their behavior as an assembly were analyzed. The results of the in situ and laboratory tests are compared and the viability of using a method based on in situ tests for the wider characterization of the type of construction under analysis evaluated.
